Industry Segments and Geographic Area Results

See Note Z to the Consolidated Financial Statements for information by operating segment and geographic area.

Competition

Historically, the chemical industry has operated in a competitive environment, and that environment is expected to continue. The Company experiences substantial competition in each of its operating segments and in each of the geographic areas in which it operates. In addition to other chemical companies, the chemical divisions of major national and international oil companies, advanced material suppliers, and producers of crop protection chemicals and agricultural biotechnology provide substantial competition in the United States and abroad. Dow competes worldwide on the basis of quality, technology, price and customer service, and for 2010, continued to be the largest U.S. producer of chemicals and plastics, in terms of sales.

Raw Materials

The Company operates in an integrated manufacturing environment. Basic raw materials are processed through many stages to produce a number of products that are sold as finished goods at various points in those processes.

The two major raw material streams that feed the integrated production of the Company’s finished goods are chlorine-based and hydrocarbon-based raw materials.

Salt, limestone and natural brine are the base raw materials used in the production of chlor-alkali products and derivatives. The Company owns salt deposits in Louisiana and Texas; Alberta, Canada; Brazil; and Germany.

The Company purchases hydrocarbon raw materials including liquefied petroleum gases, crude oil, naphtha, natural gas and condensate. These raw materials are used in the production of both saleable products and energy. The Company also purchases electric power, benzene, ethylene and propylene to supplement internal production. Expenditures for hydrocarbon feedstocks and energy accounted for 41 percent of the Company’s production costs and operating expenses for the year ended December 31, 2010. The Company purchases these raw materials on both short- and long-term contracts.

8

Other significant raw materials include acetone, aniline, phenol, styrene, methanol, carbon black, ammonia, formaldehyde and acetic acid. The Company purchases these raw materials on both short- and long-term contracts.

The Company had adequate supplies of raw materials during 2010, and expects to continue to have adequate supplies of raw materials in 2011.

Method of Distribution

All products and services are marketed primarily through the Company’s sales force, although in some instances more emphasis is placed on sales through distributors.

Twelve percent of the sales of the Feedstocks and Energy segment in 2010 were to one customer, with which the Company has an ongoing supply contract. In addition, excess ethylene glycol produced in Dow’s plants in the United States and Europe is sold to MEGlobal, a 50:50 joint venture with Petrochemical Industries Company (K.S.C.) of Kuwait. Sales to MEGlobal represented approximately 6 percent of the sales in the Feedstocks and Energy segment in 2010. Nineteen percent of the sales of the Feedstocks and Energy segment in 2010 were to two other customers with which the Company has ongoing supply contracts. Other than the sales to these customers, no significant portion of the business of any operating segment is dependent upon a single customer.

No single product accounted for more than 5 percent of the Company’s consolidated net sales in 2010.

Research and Development

The Company is engaged in a continuous program of basic and applied research to develop new products and processes, to improve and refine existing products and processes, and to develop new applications for existing products. Research and development expenses were $1,660 million in 2010, $1,492 million in 2009 and $1,310 million in 2008. At December 31, 2010, the Company employed approximately 6,300 people in various research and development activities.

Patents, Licenses and Trademarks

The Company continually applies for and obtains U.S. and foreign patents. At December 31, 2010, the Company owned 3,609 active U.S. patents and 14,028 active foreign patents as follows:

Patents Owned at December 31, 2010
	U.S.	Foreign
Electronic and Functional Materials	899	2,677
Coatings and Infrastructure Solutions	630	2,972
Agricultural Sciences	573	1,882
Performance Materials	588	2,659
Performance Plastics	673	3,095
Feedstocks and Energy	40	200
Corporate	206	543
Total	3,609	14,028

Dow’s primary purpose in obtaining patents is to protect the results of its research for use in operations and licensing. Dow is also party to a substantial number of patent licenses and other technology agreements. The Company had revenue related to patent and technology royalties totaling $191 million in 2010, $269 million in 2009 and $307 million in 2008. The Company incurred royalties to others of $111 million in 2010, $102 million in 2009 and $60 million in 2008. Dow also has a substantial number of trademarks and trademark registrations in the United States and in other countries, including the “Dow in Diamond” trademark. Although the Company considers that its patents, licenses and trademarks in the aggregate constitute a valuable asset, it does not regard its business as being materially dependent upon any single patent, license or trademark.

Financial Information About Foreign and Domestic Operations and Export Sales

In 2010, the Company derived 67 percent of its sales and had 52 percent of its property investment outside the United States. While the Company’s international operations may be subject to a number of additional risks, such as changes in currency exchange rates, the Company does not regard its foreign operations, on the whole, as carrying any greater risk than its operations in the United States. Information on sales and long-lived assets by geographic area for each of the last three years appears in Note Z to the Consolidated Financial Statements, and discussions of the Company’s risk management program for foreign exchange and interest rate risk management appear in Part I, Item 1A. Risk Factors and Part II, Item 7A. Quantitative and Qualitative Disclosures About Market Risk of the Company's Annual Report on Form 10-K for the year ended December 31, 2010 ("2010 Form 10-K") and Note J to the Consolidated Financial Statements.

Protection of the Environment

Matters pertaining to the environment are discussed in Part I, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations; and Notes A and N to the Consolidated Financial Statements.

Employees

Personnel count was 49,505 at December 31, 2010, 52,195 at December 31, 2009 and 46,102 at December 31, 2008. Headcount decreased from year-end 2009 primarily due to divestitures, including Styron, the Powder Coatings business and a portion of the Company’s acrylic monomer and specialty latex businesses, as well as actions taken related to the integration of Rohm and Haas and previously announced restructuring plans. Personnel count at December 31, 2009 was up from 46,102 at December 31, 2008, primarily due to the acquisition of Rohm and Haas, offset by declines related to restructuring activities, business divestitures and personnel transfers to a joint venture.

Other Activities

Dow engages in the property and casualty insurance and reinsurance business primarily through its Liana Limited subsidiaries.

ABOUT DOW

Dow combines the power of science and technology with the “Human Element” to passionately innovate what is essential to human progress. The Company connects chemistry and innovation with the principles of sustainability to help address many of the world’s most challenging problems such as the need for clean water, renewable energy generation and conservation, and increasing agricultural productivity. Dow’s diversified industry-leading portfolio of specialty chemical, advanced materials, agrosciences and plastics businesses deliver a broad range of technology-based products and solutions to customers in approximately 160 countries and in high growth sectors such as electronics, water, energy, coatings and agriculture. In 2010, Dow had annual sales of $53.7 billion. The Company conducts its worldwide operations through global businesses, which are reported in six operating segments: Electronic and Functional Materials, Coatings and Infrastructure Solutions, Agricultural Sciences, Performance Materials, Performance Plastics, and Feedstocks and Energy.

15

In 2010, 36 percent of the Company’s sales were to customers in North America; 34 percent were in Europe, Middle East and Africa (“EMEA”); while the remaining 30 percent were to customers in Asia Pacific and Latin America. The Company employs approximately 50,000 people and has a broad, global reach with 188 manufacturing sites in 35 countries.

2010 OVERVIEW

In 2010, Dow and the chemical industry as a whole experienced another year of improving economic conditions. Economies across much of the developed world showed signs of ongoing recovery in most end-markets as the year progressed. Meanwhile, the emerging geographies continued to lead in economic growth and, as a result, were a critical area of focus for new business opportunities and investments. As the year came to a close, however, some challenges remained, such as high unemployment in developed geographies and weakness in construction end-markets, particularly in the United States and Europe. In the face of these challenges, Dow delivered a reshaped and transformed business portfolio in 2010 – one that is increasingly targeted to growing geographic areas and end-markets, and well-balanced to mitigate uncertainties.

Dow’s reported sales increased 20 percent from 2009 to $53.7 billion, an increase of 15 percent from pro forma⁽¹⁾ 2009 sales. Excluding the impact of divestitures,⁽²⁾ sales rose 26 percent versus pro forma 2009 sales. The Company reported quarterly sequential sales gains throughout the year, excluding divestitures. Sales improvements were broad-based, with notable gains in emerging geographies around the world. Dow’s reported sales in the emerging geographies surpassed $16 billion. As the global economic recovery continued, feedstock and energy costs rose throughout the year and remained volatile. The Company’s purchased feedstock and energy costs were $5.0 billion higher than 2009, an increase of 31 percent.

The Company reported volume growth of 2 percent over 2009 pro forma sales. Excluding the impact of divestitures, Dow reported a 12 percent improvement in volume, with gains in all operating segments and geographic areas. Volume growth was notable in Electronic and Functional Materials, Agricultural Sciences, Performance Materials, and Feedstocks and Energy, all of which reported double-digit volume growth. Coatings and Infrastructure Solutions and Performance Plastics also reported solid volume gains; however, Coatings and Infrastructure Solutions continued to be impacted by continued weakness in the construction industry. Compared with 2009 pro forma sales, price rose 13 percent on a reported basis and 14 percent excluding divestitures. Price gains were most significant in Feedstocks and Energy, Performance Plastics and Performance Materials, which together reported a 21 percent improvement compared with 2009. Dow’s results from joint ventures returned to the level of earnings reported before the global economic recession, totaling $1.1 billion for the year, an increase of more than 75 percent from 2009. Earnings available for common stockholders increased from $0.32 per share in 2009 to $1.72 per share in 2010.

The Company continued to invest for growth in the year, reinforcing its strategic focus on science-based innovation and technology integration. Research and development (“R&D”) expenses rose to nearly $1.7 billion, an increase of 6 percent versus pro forma spending in the prior year, as the Company invested in growth projects in its innovation pipeline. Selling, General and Administrative (“SG&A”) expenses fell 5 percent versus 2009 pro forma spending, despite increased spending in Agricultural Sciences to support new product launches and commercial activities related to recent seed acquisitions.

Finally, the Company delivered $4.1 billion of cash from operating activities, nearly double that of 2009, and surpassed its goal to divest $2 billion in non-strategic assets in 2010. Dow ended the year with $7.0 billion of cash and cash equivalents. Throughout the year the Company had sufficient liquidity and financial flexibility to meet all of its financial obligations.

(1) The unaudited pro forma historical information is based on the historical consolidated financial statements and accompanying notes of both Dow and Rohm and Haas and has been prepared to illustrate the effects of the Company’s acquisition of Rohm and Haas, assuming the acquisition of Rohm and Haas had been consummated on January 1, 2008, and the treatment of Dow’s Calcium Chloride business as discontinued operations due to the sale of the business on June 30, 2009.

(2) Excludes sales of the Salt business of Rohm and Haas Company divested on October 1, 2009, sales related to TRN divested on September 1, 2009, sales of the acrylic monomer business and a portion of the specialty latex business divested on January 25, 2010, sales of the Powder Coatings business divested on June 1, 2010 and sales of Styron divested on June 17, 2010.

Dow focused on the execution of its strategy and delivering on the promise of its new portfolio, as well as investing for growth in businesses tied to fast-growing geographic areas and end-markets. Actions taken during 2010 included:

• Dow completed the sale of Styron to an affiliate of Bain Capital Partners for $1.6 billion. The Company also finalized the sale of its acrylic acid and esters business in Clear Lake, Texas, and its UCAR Emulsion Systems specialty latex business in North America to Arkema. With the completion of the sale of Styron, Dow exceeded its goal of divesting $5 billion in non-strategic assets in less than two years. See Note E to the Consolidated Financial Statements for additional information on divestitures.

• Dow successfully completed a two-year, multimillion-dollar project to transform its STYROFOAM™ brand insulation to a more sustainable manufacturing technology in North America, reducing the greenhouse gas emissions from production at all of its converted facilities in the region by one half.

• Dow AgroSciences announced the first planting of a SmartStax™ corn hybrid for commercial production. A revolutionary new seed trait combination, SmartStax™ received the AgProfessional Readers’ Choice 2009 New Product of the Year award.

• Dow Kokam LLC, a joint venture of Dow and Kokam America, broke ground on a world-scale lithium ion battery manufacturing facility in Michigan. The plant is expected to employ more than 800 people and have the capacity to manufacture 1.2 billion watt-hours of large format affordable lithium ion batteries.

• Dow Electronic Materials announced a multi-phase plan to expand its trimethylgallium (“TMG”) production capacity to serve the fast-growing light emitting diode (“LED”) industry. Plans include adding significant TMG capacity at existing U.S. facilities and building a new manufacturing plant in Cheonan, Korea.

• Dow and BASF received a 2010 Presidential Green Chemistry Challenge Award for jointly developed hydrogen peroxide to propylene oxide technology. The technology improves the production process of a key chemical intermediate, propylene oxide.

• Dow and Mitsui formed a 50:50 manufacturing joint venture to construct, own and operate a new membrane chlor-alkali facility at Dow’s manufacturing complex in Freeport, Texas.

• Dow became an official Worldwide Olympic Partner. This top sponsorship extends through 2020 and will allow Dow to showcase its people, products, scientific excellence and commitment to sustainable solutions on a global stage.

• Dow announced a technology breakthrough project that will increase polyolefin elastomers manufacturing capacity at its production facilities in Freeport, Texas, and Tarragona, Spain.

• Dow AgroSciences showcased a new refuge-in-the-bag concept. Pending registration by the U.S. Environmental Protection Agency, the concept will be commercialized as SmartStax™ Refuge Advanced™ and will provide a single-bag solution for refuge reduction in the U.S. Corn Belt as early as 2012.

• Dow introduced ENLIGHT™ Polyolefin Encapsulant Films that can enhance efficiencies in photovoltaic module production and lead to lower conversion costs. Commercial-scale manufacturing of the films began in Findlay, Ohio, in the fourth quarter of the year.

• Dow announced the successful startup of the Solution Linear Low Density Polyethylene II train (“SPE II”) in Thailand. SPE II is owned by Siam Polyethylene Company Limited, a joint venture of Dow and Siam Cement Group.

• Dow AgroSciences was granted a U.S. patent for crop plants that contain one of Dow AgroSciences’ new class of herbicide tolerant traits.

• DOW™ POWERHOUSE™ solar shingle received Underwriters Laboratories safety certification. The certification is a milestone toward its planned 2011 commercialization.

• Dow Electronic Materials announced it will construct a new manufacturing facility in Eastern China to meet the growing material demand to serve printed circuit board, electronic and industrial finishing, and photovoltaic industries in Asia Pacific.

17

• Dow broke ground on a new manufacturing facility in southern Vietnam for the production of polymers used in the paint, coatings, construction, packaging, home and personal care industries.

Looking to 2011, Dow expects growth in the emerging geographies to continue, driven by a broad range of leading end-markets. The Company projects that these geographic areas will continue their high rate of growth, although year-over-year comparisons will be subdued relative to recent years. Signs of improvement in industrial end-markets in North America and Europe, coupled with ongoing strength in higher-growth sectors, such as electronics, agriculture and packaging, give Dow greater optimism that growth will continue in the developed geographies. Despite these more favorable business conditions, the Company expects lingering challenges to remain, particularly slow employment growth in developed geographies. Consequently, the Company’s plans do not assume an accelerated rebound in business conditions. Dow’s success will continue to be driven by its transformed business portfolio, balanced geographic presence and investments in innovations aimed at the intersection of greatest societal need and business opportunity.

Dow’s results of operations and financial condition for the year ended December 31, 2010 are described in further detail in the following discussion and analysis.

ACQUISITION OF ROHM AND HAAS COMPANY

On April 1, 2009, the Company completed the acquisition of Rohm and Haas. Pursuant to the July 10, 2008 Agreement and Plan of Merger (the “Merger Agreement”), Ramses Acquisition Corp., a direct wholly owned subsidiary of the Company, merged with and into Rohm and Haas (the “Merger”), with Rohm and Haas continuing as the surviving corporation becoming a direct wholly owned subsidiary of the Company.

The Company pursued the acquisition of Rohm and Haas to make the Company a leading specialty chemicals and advanced materials company, combining the two organizations’ best-in-class technologies, broad geographic reach and strong industry channels to create a business portfolio with significant growth opportunities.

Pursuant to the terms and conditions of the Merger Agreement, each outstanding share of Rohm and Haas common stock was converted into the right to receive cash of $78 per share, plus additional cash consideration of $0.97 per share. The additional cash consideration represented 8 percent per annum on the $78 per share consideration from January 10, 2009 to the closing of the Merger, less dividends declared by Rohm and Haas with a dividend record date between January 10, 2009 and the closing of the Merger. All options to purchase shares of common stock of Rohm and Haas granted under the Rohm and Haas stock option plans and all other Rohm and Haas equity-based compensation awards, whether vested or unvested as of April 1, 2009, became fully vested and converted into the right to receive cash of $78.97 per share, less any applicable exercise price. Total cash consideration paid to Rohm and Haas shareholders was $15.7 billion.

The Company achieved its synergy targets related to the acquisition a full quarter ahead of schedule, with realized savings of $1.4 billion including increased purchasing power for raw materials; manufacturing and supply chain work process improvements; and the elimination of redundant corporate overhead for shared services and governance. The integration of Rohm and Haas was substantially complete at December 31, 2010.

On July 31, 2009, the Company entered into a definitive agreement for the sale of certain acrylic monomer and specialty latex assets, as required by the United States Federal Trade Commission (“FTC”), for approval of the April 1, 2009 acquisition of Rohm and Haas (see Note E to the Consolidated Financial Statements). The transaction closed on January 25, 2010.

RESULTS OF OPERATIONS

Results of Rohm and Haas are included in the Company’s consolidated results from the April 1, 2009 acquisition forward. In order to provide the most meaningful comparison of results of operations, some of the comparisons made in this section are presented on a pro forma basis, reflecting the combination of Dow and Rohm and Haas assuming the transaction had been consummated on January 1, 2008.

Net sales for 2010 were $53.7 billion, up 20 percent from reported net sales of $44.9 billion in 2009 and up 15 percent from pro forma net sales of $46.6 billion in 2009. Sales increased in 2010 across all segments and geographic areas, with higher prices contributing 13 percent of the improvement and increased volume adding 2 percent over 2009 pro forma results. The increase in price was largely driven by higher feedstock and energy costs, and was most pronounced in Feedstocks and Energy (up 28 percent), Performance Plastics (up 20 percent) and Performance Materials (up 12 percent). Double-digit price increases were reported in all geographic areas. Volume was mixed across the segments, with significant gains in Electronic and Functional Materials (up 20 percent) and Agricultural Sciences (up 11 percent) tempered by the impact of recent divestitures, which resulted in declines in Coatings and Infrastructure Solutions (down 3 percent) and Performance Plastics

18

(down 3 percent). The Company’s recent divestitures included the Styron business unit (“Styron”) divested on June 17, 2010; the Powder Coatings business divested on June 1, 2010; a portion of the acrylic monomer business and a portion of the specialty latex business divested on January 25, 2010; the Salt business of Rohm and Haas Company divested on October 1, 2009; and the Company’s ownership interest in Total Raffinaderij Nederland N.V. (“TRN”) divested on September 1, 2009. See Note E to the Consolidated Financial Statements for additional information concerning the Company’s divestitures. Excluding these divestitures, volume increased 12 percent compared with 2009 on a pro forma basis, with volume improvement in all segments and geographic areas.

On a pro forma basis, net sales for 2009 were down 30 percent from $66.9 billion in 2008. Compared with 2008, prices fell 17 percent, with decreases in all segments and double-digit declines in all geographic areas. Price declines were most pronounced in Feedstocks and Energy (down 28 percent), Performance Plastics (down 23 percent) and Performance Materials (down 15 percent), driven by significantly lower feedstock and energy costs. Volume decreased 13 percent as a result of the continued weakness in the global economy, with declines in all operating segments except Agricultural Sciences, which reported growth of 4 percent. From a geographic perspective, the volume decrease was most pronounced in North America, down 18 percent from 2008 levels, which were already reduced due to Hurricanes Gustav and Ike which hit the U.S. Gulf Coast, resulting in temporary plant outages.

Sales in the United States accounted for 33 percent of total sales in 2010 and 32 percent of total sales in 2009 and 2008. See the Sales Price and Volume tables at the end of the section titled “Segment Results” for details regarding the change in sales by operating segment and geographic area. In addition, sales and other information by operating segment and geographic area are provided in Note Z to the Consolidated Financial Statements.

Gross margin for 2010 was $7.9 billion, compared with $5.7 billion in 2009 and $5.4 billion in 2008. The improvement in gross margin compared with 2009 reflected higher prices, which more than offset a $5.0 billion increase in purchased feedstock and energy costs; increased volume in Electronic and Functional Materials, Agricultural Sciences, and other higher margin product lines; and significantly higher operating rates. In 2010, gross margin was reduced by a $50 million labor-related litigation matter that was included in “Cost of Sales” and reflected in Corporate, and $91 million in asset impairments and related costs in the Polyurethanes business, the Epoxy business and Dow Automotive Systems included in “Cost of Sales” and reflected in Performance Materials.

In 2009, despite a significant drop in sales compared with 2008, gross margin increased as a result of the acquisition of Rohm and Haas, a $10.2 billion decrease in feedstock and energy costs, lower other raw material and freight costs, and the favorable impact of currency on costs. In 2009, gross margin was reduced by a one-time increase in cost of sales of $209 million related to the fair value step-up of inventories acquired from Rohm and Haas on April 1, 2009, and sold in the second quarter of 2009. The increase was included in “Cost of sales” and reflected in the operating segments as follows: $75 million in Electronic and Functional Materials, $81 million in Coatings and Infrastructure Solutions and $53 million in Performance Plastics. Gross margin in 2009 was also reduced by hedging losses of $56 million related to the sale of the Company’s 45 percent ownership interest in TRN (see Note E to the Consolidated Financial Statements), reflected in the Feedstocks and Energy segment.

Gross margin in 2008 was negatively impacted by Hurricanes Gustav and Ike, which hit the U.S. Gulf Coast, causing temporary outages for several of the Company’s Gulf Coast production facilities and resulting in $181 million in additional manufacturing expenses, including the repair of property damage, clean-up costs, unabsorbed fixed costs and inventory write-offs. The expenses were included in “Cost of sales” and reflected in the operating segments as follows: $2 million in Electronic and Functional Materials, $3 million in Coatings and Infrastructure Solutions, $2 million in Agricultural Sciences, $74 million in Performance Materials, $22 million in Performance Plastics, $69 million in Feedstocks and Energy, with the remaining $9 million in Corporate. In addition, gross margin in 2008 was reduced by legal expenses and other costs of $69 million related to the K-Dow transaction; these costs were expensed (to “Cost of sales”) upon Petrochemical Industries Company (K.S.C.) of Kuwait’s refusal to close the K-Dow transaction (reflected in Corporate).

Dow’s global plant operating rate was 83 percent of capacity in 2010, compared with 74 percent in 2009 and 77 percent in 2008. Operating rates improved in 2010, with both increased demand and actions taken by management to rationalize capacity through shutdowns and divestitures contributing to the improvement. In 2009, operating rates were down from 2008, reflecting the downturn in the global economy. In 2008, operating rates were impacted by lower demand resulting from the slowing global economy, especially in the second half of the year, as well as by Hurricanes Gustav and Ike which hit the U.S. Gulf Coast in the third quarter of 2008. Depreciation expense was $2,289 million in 2010, $2,291 million in 2009 and $2,016 million in 2008.

19

Personnel count was 49,505 at December 31, 2010, down from 52,195 at December 31, 2009. Headcount decreased from year-end 2009 primarily due to divestitures, including Styron, the Powder Coatings business and a portion of the Company’s acrylic monomer and specialty latex businesses, as well as restructuring activities associated with the integration of Rohm and Haas and previously announced restructuring plans. Personnel count at December 31, 2009 was up from 46,102 at December 31, 2008, primarily due to the acquisition of Rohm and Haas, offset by declines related to restructuring activities, business divestitures and personnel transfers to a joint venture.

Research and development (“R&D”) expenses were $1,660 million in 2010, compared with $1,492 million in 2009 and $1,310 million in 2008. The increase in R&D expenses in 2010 reflected the Company’s planned spending on strategic corporate growth initiatives and continued investments in the Agricultural Sciences segment, partially offset by the elimination of R&D expenses related to the divestiture of Styron. In 2009, R&D expenses increased compared with 2008, due to the acquisition of Rohm and Haas and planned growth initiatives in the Agricultural Sciences segment, partially offset by cost savings in other segments.

Selling, general and administrative (“SG&A”) expenses were $2,609 million in 2010, compared with $2,487 million in 2009 and $1,966 million in 2008. SG&A expenses increased 5 percent from 2009, as selling expenses for all segments increased commensurate with higher sales and the full-year impact of the Rohm and Haas acquisition in 2010. In 2009, SG&A expenses increased compared with 2008, primarily due to the acquisition of Rohm and Haas, partially offset by cost savings initiatives.

The following table illustrates the relative size of the primary components of total production costs and operating expenses of Dow. More information about each of these components can be found in other sections of Management’s Discussion and Analysis of Financial Condition and Results of Operations, Notes to the Consolidated Financial Statements, and Part II, Item 6. Selected Financial Data of the 2010 Form 10-K.

Amortization of intangibles was $509 million in 2010, $399 million in 2009 and $92 million in 2008. The increase in amortization of intangibles in 2010 reflected the full-year impact of the amortization of intangible assets acquired from Rohm and Haas. Amortization of intangibles in 2009 increased from 2008 due to amortization of the fair value of intangible assets acquired from Rohm and Haas from the April 1, 2009 acquisition date forward. See Notes D and I to the Consolidated Financial Statements for additional information regarding the acquisition of Rohm and Haas and goodwill and other intangible assets.

The Company performs annual goodwill impairment tests during the fourth quarter of the year. During the fourth quarter of 2010, no impairment indicators related to the carrying value of goodwill were identified. During the fourth quarter of 2009, it was determined that goodwill associated with the Dow Haltermann business unit was impaired. The impairment was based on a review performed by management in which discounted cash flows did not support the carrying value of the goodwill. As a result, the Company recorded a goodwill impairment loss of $7 million, impacting the Performance Materials segment. During the fourth quarter of 2008, it was determined that goodwill associated with the Dow Automotive Systems and Polypropylene reporting units was impaired. The impairment was based on a review performed by management in which discounted cash flows did not support the carrying value of the goodwill. The Company recorded charges totaling $239 million for goodwill impairment losses, including $209 million for the Dow Automotive Systems reporting unit (impacting the Performance Materials segment) and $30 million for the Polypropylene reporting unit (impacting the Performance Plastics segment). See Note I to the Consolidated Financial Statements for additional information regarding goodwill.

20

During 2010, the Company recorded adjustments of $29 million to the 2009 restructuring charge for additional asset impairments, exit and disposal activities, and severance; and adjustments of $3 million to the 2008 restructuring charge to reduce the severance reserve. The adjustments were reflected in Electronic and Functional Materials ($8 million charge), Coatings and Infrastructure Solutions ($20 million charge) and Corporate ($2 million credit).

In June 2009, Dow’s Board of Directors approved a restructuring plan that incorporated actions related to the Company’s acquisition of Rohm and Haas as well as additional actions to advance the Company’s strategy and to respond to continued weakness in the global economy. The restructuring plan included the shutdown of a number of facilities and a global workforce reduction. As a result, the Company recorded restructuring charges totaling $677 million in the second quarter of 2009, which included asset write-downs and write-offs of $454 million, severance costs of $155 million and costs associated with exit or disposal activities of $68 million. The impact of the charges was shown as “Restructuring charges” in the consolidated statements of income and was reflected in the Company’s segment results as follows: $48 million in Electronic and Functional Materials, $262 million in Coatings and Infrastructure Solutions, $2 million in Performance Materials, $1 million in Performance Plastics and $140 million in Feedstocks and Energy, with the remaining $224 million in Corporate.

During 2009, the Company recorded the following adjustments to its restructuring plans: in the first quarter of 2009, the Company recorded additional severance of $19 million related to 2008 restructuring activities, reflected in Corporate; in the second quarter of 2009, the Company recorded a $15 million reduction in the 2007 restructuring reserve, reflected in the Agricultural Sciences segment; and in the fourth quarter of 2009, the Company recorded a $5 million reduction to the 2007 restructuring reserve and $13 million in additional charges related to the 2009 restructuring activities, both reflected in Corporate.

On December 5, 2008, the Company’s Board of Directors approved a restructuring plan as part of a series of actions to advance the Company’s strategy and respond to the severe economic downturn that began in the latter part of 2008. The restructuring plan included the shutdown of a number of facilities and a global workforce reduction, which were substantially complete by the end of 2010. As a result of the shutdowns and global workforce reduction, the Company recorded restructuring charges of $785 million in the fourth quarter of 2008. The charges consisted of asset write-downs and write-offs of $336 million, costs associated with exit or disposal activities of $128 million and severance costs of $321 million. The impact of the charges is shown as “Restructuring charges” in the consolidated statements of income and was reflected in the Company’s segment results as follows: $10 million in Electronic and Functional Materials, $16 million in Coatings and Infrastructure Solutions, $120 million in Performance Materials, $122 million in Performance Plastics and $87 million in Feedstocks and Energy, with the remaining $430 million in Corporate. In addition to the charges related to the 2008 restructuring plan, in the fourth quarter of 2008, the Company recorded additional adjustments of $54 million related to the 2007 and 2006 restructuring plans, primarily impacting the Performance Plastics segment.

See Note C to the Consolidated Financial Statements for details on the restructuring charges.

During 2009, a charge of $7 million was recorded for purchased in-process research and development (“IPR&D”) related to the purchase of lithium ion battery technology by the Ventures business, impacting Corporate. During 2008, charges totaling $44 million were recorded for purchased IPR&D related to acquisitions within the Agricultural Sciences segment. See Note D to the Consolidated Financial Statements for information regarding these charges.

Charges totaling $143 million in 2010, $166 million in 2009 and $49 million in 2008 were recorded for integration costs, legal expenses and other transaction costs related to the acquisition of Rohm and Haas; these charges were reflected in Corporate. In 2009, the Company also recorded $60 million in acquisition-related retention costs. These costs were recorded in “Cost of sales,” “Research and development expenses,” and “Selling, general and administrative expenses” in the consolidated statements of income and reflected in Corporate. The integration of Rohm and Haas was substantially complete at December 31, 2010.

Dow’s share of the earnings of nonconsolidated affiliates in 2010 was $1,112 million, compared with $630 million in 2009 and $787 million in 2008. In 2010, increased earnings at Dow Corning Corporation (“Dow Corning”), EQUATE Petrochemical Company K.S.C. (“EQUATE”), MEGlobal, The Kuwait Olefins Company K.S.C. and The Kuwait Styrene Company K.S.C. more than offset a decline in earnings resulting from the September 2009 divestitures of the Company’s ownership interests in TRN and the OPTIMAL Group of Companies (“OPTIMAL”), and the June 2010 divestiture of the Company’s ownership interest in Americas Styrenics LLC. See Note E to the Consolidated Financial Statements for additional information concerning the Company’s recent divestitures. In 2009, equity earnings declined compared with 2008, reflecting the overall decrease in global demand and poor economic conditions, with EQUATE, Dow Corning and OPTIMAL reporting the largest declines. Improved results were reported by The Kuwait Olefins Company K.S.C. in 2009 following the successful startup of additional production capacity for ethylene oxide/ethylene glycol and increased production of ethylene in support of additional polyethylene capacity. Equity earnings for 2009 were negatively impacted by a $65 million impairment charge related to Equipolymers and the Company’s $29 million share of a restructuring charge related to Dow Corning. See Note H to the Consolidated Financial Statements for additional information on nonconsolidated affiliates.

Sundry income - net includes a variety of income and expense items such as the gain or loss on foreign currency exchange, dividends from investments, and gains and losses on sales of investments and assets. Sundry income - net for 2010 was $125 million, compared with $891 million in 2009 and $89 million in 2008. In 2010, sundry income - net included a net $27 million gain on the Styron divestiture, reflected in the following operating segments: Performance Materials ($20 million) and Performance Plastics ($7 million). In addition to the net gain on the Styron divestiture, Sundry income - net for 2010 included net gains on several other divestitures, partially offset by a loss of $46 million related to the early extinguishment of debt and a charge of $47 million for an obligation related to a past divestiture (both reflected in Corporate). Sundry income - net in 2009 included a gain of $513 million on the sale of the Company’s ownership interest in TRN and related inventory on September 1, 2009 (reflected in Feedstocks and Energy) and a gain of $339 million on the sale of the Company’s ownership interest in OPTIMAL on September 30, 2009 (reflected in Performance Materials ($146 million) and Feedstocks and Energy ($193 million)). Sundry income - net in 2009 was reduced by a loss of $56 million related to the Company’s early extinguishment of debt in the third quarter of 2009 (reflected in Corporate). In 2008, sundry income - net reflected net gains on several small divestitures and asset sales, partially offset by unfavorable foreign exchange hedging results. See Note E to the Consolidated Financial Statements for additional information concerning the Company’s recent divestitures. See “Liquidity and Capital Resources” for additional information on the Company’s early extinguishment of debt.

Net interest expense (interest expense less capitalized interest and interest income) was $1,436 million in 2010, down from $1,532 million in 2009, reflecting lower debt financing costs during the year. In 2009, net interest expense increased compared with net interest expense of $562 million in 2008, due to debt financing activity for the April 1, 2009 acquisition of Rohm and Haas. Interest expense (net of capitalized interest) and amortization of debt discount totaled $1,473 million in 2010, $1,571 million in 2009 and $648 million in 2008. See “Liquidity and Capital Resources” for additional information regarding debt financing activity. Interest income was $37 million in 2010, down from $39 million in 2009 and $86 million in 2008. Interest rates on investments in 2010 were consistent with those of 2009, following a decline from 2008 rates, resulting in lower interest income in 2010 and 2009 compared with 2008.

The provision for income taxes was $481 million, compared with a credit of $97 million in 2009 and a provision of $651 million in 2008. The Company’s effective tax rate fluctuates based on, among other factors, where income is earned and the level of income relative to tax credits available. For example, as the percentage of foreign sourced income increases, the Company’s effective tax rate declines. The Company’s tax rate is also influenced by the level of equity earnings, since most of the earnings from the Company’s equity company investments are taxed at the joint venture level.

The tax rate for 2010 was positively impacted by a high level of equity earnings as a percentage of total earnings, the release of a tax valuation allowance, a tax law change, and improved financial results in jurisdictions with tax rates that are lower than the U.S. statutory rate. These factors resulted in an effective tax rate of 17.2 percent for 2010.

In 2009, the effective tax rate was negative 20.7 percent, and was reduced by several factors: a significantly higher level of equity earnings as a percent of total earnings, favorable accrual-to-return adjustments in various geographies, the recognition of domestic losses and an improvement in financial results in jurisdictions with tax rates that are lower than the U.S. statutory rate. In 2008, the effective tax rate was 51.0 percent, reflecting the negative impact of goodwill impairment losses that were not deductible for tax purposes.

On June 30, 2009, the Company sold the Calcium Chloride business and recognized a $162 million pretax gain. The results of operations related to the Calcium Chloride business have been reclassified and reported as income from discontinued operations for all periods presented. Income from discontinued operations (net of income taxes) was $110 million ($0.10 per share) in 2009, compared with $28 million ($0.03 per share) in 2008.

Net income attributable to noncontrolling interests was $11 million in 2010, $28 million in 2009 and $75 million in 2008. Net income attributable to noncontrolling interests declined in 2010 compared with 2009 as a result of the July 2009 redemption of the Tornado Finance V.O.F. preferred partnership units. Net income attributable to noncontrolling interests declined in 2009 compared with 2008 as a result of the third quarter of 2008 redemption by the outside partner of its ownership interest in Hobbes Capital S.A. See Note U to the Consolidated Financial Statements for additional information concerning these noncontrolling interests.

Preferred stock dividends of $340 million were recognized in 2010, compared with preferred stock dividends of $312 million in 2009. Dividends related to the Company’s Cumulative Convertible Perpetual Preferred Stock, Series A were $340 million in 2010 and $255 million in 2009. The remaining $57 million of dividends in 2009 related to the Cumulative Perpetual Preferred Stock, Series B and Cumulative Convertible Perpetual Preferred Stock, Series C, both of which were retired in the second quarter of 2009. See Notes W and X to the Consolidated Financial Statements for additional information.

Net income available for common stockholders was $1,970 million ($1.72 per share) in 2010, compared with $336 million ($0.32 per share) in 2009 and $579 million ($0.62 per share) in 2008.

The reported results by operating segment can be found in Note Z to the Consolidated Financial Statements. The Company uses EBITDA (which Dow defines as earnings (i.e. "Net Income") before interest, income taxes, depreciation and amortization) as its measure of profit/loss for segment reporting purposes. EBITDA by operating segment includes all operating items relating to the businesses, except depreciation and amortization; items that principally apply to the Company as a whole are assigned to Corporate. Note Z also includes a reconciliation of EBITDA to “Income from Continuing Operations Before Income Taxes.”

In order to provide the most meaningful comparison of results by operating segment, the following discussion and analysis compares actual results for 2010 to actual results for the last nine months of 2009 plus pro forma historical results for the first quarter of 2009 and pro forma historical results for 2008. The unaudited pro forma historical segment information is based on the historical consolidated financial statements and accompanying notes of both Dow and Rohm and Haas and was prepared to illustrate the effects of the Company’s acquisition of Rohm and Haas, assuming the acquisition of Rohm and Haas had been consummated on January 1, 2008. In addition, the unaudited pro forma historical segment information reflects the impact of increased depreciation and amortization expense resulting from the fair valuation of assets acquired from Rohm and Haas assuming that the transaction had been consummated on January 1, 2008.

The unaudited pro forma historical segment information, prepared following the April 1, 2009 acquisition of Rohm and Haas, is not necessarily indicative of the results of operations that would have actually occurred had the acquisition been completed as of the date indicated, nor is it indicative of the future operating results of the combined company. The unaudited

2010 Actual Versus 2009 Pro Forma

Electronic and Functional Materials sales were $4,203 million for 2010, up 20 percent from $3,509 million in 2009, entirely due to volume. Volume was strong across all geographic areas and all businesses, reflecting improved economic conditions in the food and nutrition, personal care and electronics industries. Prices were flat for the segment, as competitive pricing pressure on more mature products was countered by the introduction of new products with higher margins and targeted price increases in response to escalating raw materials costs. EBITDA for 2010 was $1,052 million, a significant increase from $656 million in 2009, primarily due to higher volume and higher equity earnings from Dow Corning. Results for 2010 were negatively impacted by an $8 million adjustment to the 2009 restructuring charge related to the closure of a small manufacturing facility. EBITDA for 2009 was negatively impacted by an increase in cost of sales of $75 million related to the fair valuation of Rohm and Haas inventories, restructuring charges of $48 million (see Note C to the Consolidated Financial Statements) and $8 million of the Company's share of a restructuring charge recognized by Dow Corning.

Dow Electronic Materials sales in 2010 were up 29 percent from 2009, driven by higher volume, especially in Asia Pacific, primarily due to strong underlying demand in the electronics industry and new product introductions. Semiconductor foundry utilization rates across the industry improved significantly compared with 2009 and were running in excess of 90 percent throughout most of 2010, supporting higher demand for chemical mechanical planarization pads and materials used in printed circuit boards. Demand for liquid crystal display (“LCD”) chemicals and film materials that replace glass used in plasma display panels also increased. New product launches and strategic customer wins helped drive a 39 percent volume growth for Dow Electronic Materials in Asia Pacific.

Functional Materials sales in 2010 were up 13 percent from 2009, entirely related to volume. Volume increased in all geographic areas and all major businesses due to higher demand for specialty biocides and cellulosics used in food, nutrition and personal care products.

2009 Versus 2008 (Pro Forma Comparison)

Electronic and Functional Materials sales were $3,509 million for 2009, down 20 percent from $4,371 million in 2008, as volume dropped 16 percent and prices declined 4 percent. The decrease in volume was broad-based, the result of the global downturn in the electronics and construction industries. EBITDA for 2009 was $656 million, compared with $999 million for 2008. Despite the impact of lower SG&A expenses and lower raw material costs during 2009, EBITDA declined as a result of lower volume; a decrease in equity earnings from Dow Corning, which included $8 million of the Company's share of a restructuring charge; an increase in cost of sales of $75 million related to the fair valuation of Rohm and Haas inventories; and restructuring charges of $48 million. EBITDA for 2008 included a gain on the sale of Rohm and Haas’ investment in UP Chemical Company of $87 million, restructuring charges of $22 million and hurricane-related costs of $3 million.

Dow Electronic Materials sales for 2009 were down 23 percent versus 2008, driven by a 22 percent decrease in volume and a 1 percent decline in prices. Volume declined in all geographic areas reflecting the global economic downturn. Asia Pacific, however, reported signs of recovery in the second half of 2009 due to a rebound in electronics demand and re-stocking within the value chain.

Functional Materials sales for 2009 were down 17 percent versus 2008, as volume decreased 11 percent and prices declined 6 percent. Volume declined across all major businesses. Volume declines in cellulosics were driven by weaker construction industry conditions.

Electronic and Functional Materials Outlook for 2011

Electronic and Functional Materials sales are expected to increase in 2011, driven by continued demand in the electronics and health care industries, especially in emerging geographies.

Dow Electronic Materials sales volume is expected to increase, driven by higher demand across electronics end-markets especially in mobile phones, LCD televisions and tablet devices. Industry semiconductor foundry utilization rates are expected to remain near current levels in 2011. In the fourth quarter of 2010, Dow Electronic Materials broke ground on two new manufacturing facilities in Asia Pacific. The construction of the new metalorganic precursor manufacturing plant in Cheonan, Korea is part of a multi-phase plan announced in June 2010 to expand trimethylgallium production capacity to meet the surging demand for the material in LED and related electronics applications. The facility is expected to be operational in early 2011. A new Eastern China manufacturing facility at the Company’s Zhangjiagang site will meet growing demand for materials for printed circuit boards, electronic and industrial finishing and photovoltaics in Asia. Start-up is planned for late 2011.

Functional Materials sales are also expected to increase, especially in emerging geographies, due to higher demand for specialty biocides used in personal care and cosmetics applications. Higher demand for cellulosics used in food and nutrition is also expected. Several innovation projects across the business are anticipated to drive higher sales.

COATINGS AND INFRASTRUCTURE SOLUTIONS

The Coatings and Infrastructure Solutions segment consists of the following businesses: Dow Building and Construction, Dow Coating Materials, Dow Water and Process Solutions, and Performance Monomers; and includes a portion of the Company's share of the results of Dow Corning Corporation, a joint venture of the Company. These businesses produce a wide variety of products with a broad range of applications – adhesives and sealants, construction materials (insulation, weatherization and vinyl applications), cellulosic-based construction additives, raw materials for architectural paints and industrial coatings, and technologies used for water purification.

2010 Actual Versus 2009 Pro Forma

Coatings and Infrastructure Solutions sales were $6,596 million for 2010, up 6 percent from $6,243 million in 2009. Compared with 2009, price was up 9 percent, while volume declined 3 percent. Price improved in all geographic areas. The price improvement was most pronounced in Performance Monomers, driven by higher raw material costs, and Dow Coating Materials, where raw material supply constraints led to a favorable pricing environment during 2010. Volume declined due to the United States Federal Trade Commission ("FTC") required divestiture of certain specialty latex assets on January 25, 2010 (related to the April 1, 2009 acquisition of Rohm and Haas) and the June 1, 2010 divestiture of the Powder Coatings business. Excluding these divestitures, volume increased 7 percent compared with 2009. The increase in volume was primarily driven by Performance Monomers as well as higher demand for insulation products, ion exchange resins and reverse osmosis membranes.

EBITDA for 2010 was $1,230 million, up from $648 million in 2009. EBITDA was negatively impacted in 2010 by $15 million in adjustments to the 2009 restructuring plan and $5 million in restructuring charges related to the divestiture of the specialty latex assets. EBITDA for 2009 was negatively impacted by $262 million of restructuring charges primarily related to the Company’s actions to optimize facilities following the acquisition of Rohm and Haas, an increase in cost of sales of $81 million related to the fair valuation of Rohm and Haas inventories and $21 million of the Company's share of a restructuring charge recognized by Dow Corning. Compared with last year, higher prices, improved operating rates, lower SG&A expenses and higher equity earnings from Dow Corning more than offset increases in raw material costs. See Notes C and D to the Consolidated Financial Statements for additional information on restructuring charges and the acquisition of Rohm and Haas.

2009 Versus 2008 (Pro Forma Comparison)

Coatings and Infrastructure Solutions sales were $6,243 million for 2009, down 25 percent from $8,358 million in 2008, as volume dropped 16 percent and prices fell 9 percent. The volume decline was due to weak demand for architectural and industrial coatings and other materials used in residential and commercial construction. Demand for coatings and construction materials was down significantly due to the downturn in the housing industry, particularly in North America and EMEA. Volume declines in ion exchange resins and reverse osmosis membranes, particularly for large industrial water projects, were principally due to lower infrastructure spending and cautious capital spending by customers. The decrease in price was largely driven by a decline in feedstock and energy and other raw material costs.

27

EBITDA for 2009 was $648 million compared with $1,082 million for 2008. EBITDA for 2009 was reduced by $262 million of restructuring charges, an $81 million increase in cost of sales related to the fair valuation of Rohm and Haas inventories and $21 million of the Company's share of a restructuring charge recognized by Dow Corning. EBITDA declined in 2009 as a result of these charges, the decrease in sales and lower equity earnings from Dow Corning despite lower raw material and freight costs and lower SG&A expenses. EBITDA for 2008 was negatively impacted by $30 million of restructuring charges and $22 million of hurricane-related costs.

Coatings and Infrastructure Solutions Outlook for 2011

Coatings and Infrastructure Solutions sales are expected to increase in 2011, driven by the gradual recovery of new residential construction in the United States and continued growth in insulation products due to more stringent energy codes. Innovation projects, like POWERHOUSE^™ solar shingles, are expected to commercially launch in the second half of 2011. Dow Coating Materials sales are also expected to increase, especially in emerging geographies, driven by higher demand for architectural coatings. Demand for industrial coatings is expected to remain flat. Dow Water and Process Solutions sales are expected to increase, driven by higher demand for ion exchange resins and reverse osmosis membranes used in large industrial water desalination projects. Price increases are expected across most businesses in response to projected higher raw material costs in 2011.

2010 Actual Versus 2009 Pro Forma

Agricultural Sciences sales were a record $4,869 million in 2010, up from $4,537 million in 2009. Sales increased 7 percent, with volume up 11 percent and price down 4 percent. With the launch of SmartStax^™ technology, growth in the corn, soybean and cotton portfolios, and new seed acquisitions, the Seeds, Traits and Oils business reported a 25 percent increase in volume. New agricultural chemicals products also posted strong volume growth, increasing 34 percent as pyroxsulam cereal herbicide sales doubled, and penoxsulam rice herbicide, aminopyralid range and pasture herbicide and spinetoram insecticide recorded double-digit growth. The price decline when compared with the same period last year was the result of continued generic competition on commodity agricultural chemicals. AgroFresh reported modest volume growth in all geographic areas in 2010.

EBITDA for 2010 was $640 million, compared with $577 million in 2009. EBITDA increased as sales volume gains in the Seeds, Traits and Oils business, new product growth, and continued portfolio management more than offset lower pricing on commodity agricultural chemicals and increased investment in R&D and SG&A to support growth initiatives. Results for 2009 were favorably impacted by a $15 million reduction in the 2007 restructuring reserve, originally related to pre-acquisition contract termination fees between the Company and Rohm and Haas. See Note C to the Consolidated Financial Statements for information on restructuring charges.

2009 Versus 2008 (Pro Forma Comparison)

Agricultural Sciences sales were $4,537 million in 2009, down from $4,609 million in 2008. Sales decreased 2 percent as prices declined 6 percent (half due to currency), while volume increased 4 percent. Reduced farm income and tighter credit markets in many regions created significant downward pricing pressure during 2009. Prices declined as farm income was negatively impacted by falling crop commodity prices combined with the relatively higher costs of purchases made earlier in the year. The commodity product glyphosate accounted for the vast majority of the overall decline in prices compared with 2008. Volume increased as new seed acquisitions and growth in the corn, soybean and sunflower portfolios resulted in 33 percent sales growth in the Seeds, Traits and Oils business. Volume for new agricultural chemicals products also increased as pyroxsulam sales more than tripled and penoxsulam and spinetoram had continued strong growth. AgroFresh posted record sales volume growth compared with 2008 as SMARTFRESH™ technology for maintaining the just-harvested quality and freshness of fruits and vegetables continued to receive excellent channel support in all geographic areas.

EBITDA for 2009 was $577 million, compared with $892 million in 2008. EBITDA was negatively impacted by higher costs associated with the valuation of inventory based on reduced raw material prices, unfavorable currency exchange rates, glyphosate price declines, and increased R&D and SG&A expenses to support growth initiatives. Results for 2009 were favorably impacted by a $15 million reduction in the 2007 restructuring reserve, originally related to pre-acquisition contract termination fees between the Company and Rohm and Haas. EBITDA for 2008 was negatively impacted by charges of $44 million for IPR&D related to seed acquisitions, $3 million in restructuring charges and $2 million related to the 2008 hurricanes.

Agricultural Sciences Outlook for 2011

Agricultural Sciences sales for 2011 are expected to grow above the levels achieved in 2010. Volume is anticipated to increase in key regions as the agricultural industry benefits from strong global demand for agricultural products. SmartStax™technology, which is already considered an industry leading corn stacked trait, will enter its second year of commercial production in 2011. Continued sales growth of new products pyroxsulam, spinetoram, penoxsulam, and aminopyralid is also anticipated in 2011. Investments in technology, capacity and geographic reach in the Seeds, Traits and Oils business remain a priority.

2010 Actual Versus 2009 Pro Forma

Performance Materials sales for 2010 were $13,957 million, up 17 percent from $11,900 million in 2009. Price increased 12 percent and volume increased 5 percent, with price and volume improvements reported in all geographic areas and most businesses. Chlorinated Organics experienced a double-digit price increase due to improved pricing in refrigerants, fluoropolymers and solvent applications. Epoxy, Dow Plastic Additives, Oxygenated Solvents and Polyurethanes also experienced double-digit price increases driven primarily by increased feedstock and energy and other raw material costs. Compared with last year, volume was negatively impacted by the sale of Emulsion Polymers, Synthetic Rubber and certain Dow Automotive Systems assets as part of the Styron divestiture completed on June 17, 2010. Excluding the impact of this divestiture, volume was up 15 percent with double-digit increases in all geographies. Particularly strong growth was reported by the Epoxy business, up 30 percent driven by improved demand for resins used in the automotive and electronic industries and new product supply agreements with Styron. Dow Automotive Systems reported significant volume growth of 24 percent due to strong demand in the automotive industry. Demand for formulations related to alternative energy and energy efficiency rebounded from the global economic slowdown, contributing to a 21 percent volume gain in Dow Formulated Systems. Oxygenated Solvents also reported a 21 percent volume increase driven by the economic recovery, especially in North America and Asia Pacific.

EBITDA for 2010 was $1,714 million, compared with $1,567 million in 2009. Compared with last year, EBITDA improved as higher prices and volume, and the benefits of improved operating rates and lower R&D expenses more than offset higher raw material costs, higher manufacturing and supply chain costs and lower equity earnings related to costs associated with the start-up of a new joint venture. EBITDA in 2010 was negatively impacted by $48 million of asset impairment charges and related costs in the Polyurethanes business, a $34 million charge for the write-off of capital project spending and related costs in the Epoxy business, and a $9 million write-off of capital spending in Dow Automotive Systems. EBITDA in 2010 was favorably impacted by a $20 million net gain on the sale of Styron. EBITDA in 2009 was positively impacted by a $146 million gain on the sale of the Company's ownership interest in OPTIMAL, partially reduced by a $7 million charge related to the impairment of goodwill associated with the Dow Haltermann reporting unit (see Note I to the Consolidated Financial Statements) and $2 million of restructuring charges. See Note C to the Consolidated Financial Statements for information on restructuring charges.

2009 Versus 2008 (Pro Forma Comparison)

Performance Materials sales were $11,900 million in 2009, down from $16,845 million in 2008. Sales declined 29 percent with prices declining 15 percent and volume declining 14 percent. Price decreased in all businesses, driven by lower feedstock and energy and other raw material costs. The decrease in volume was broad-based, impacting all businesses, driven by weak global demand especially in the automotive and construction industries.

EBITDA for 2009 was $1,567 million, compared with $1,066 million in 2008. EBITDA increased from 2008 as a decrease in feedstock and energy and other raw material costs, lower freight costs, and lower R&D and SG&A expenses more than offset the declines in selling prices and volume. EBITDA in 2009 was positively impacted by a $146 million gain on the sale of the Company's ownership interest in OPTIMAL, partially reduced by a $7 million charge related to the impairment of goodwill associated with the Dow Haltermann reporting unit and $2 million of restructuring charges. EBITDA for 2008 was negatively impacted by a goodwill impairment loss of $209 million associated with Dow Automotive Systems (See Note I to the Consolidated Financial Statements), restructuring charges of $122 million related to the closure or impairment of several manufacturing facilities and costs of $74 million related to the U.S. Gulf Coast hurricanes.

Performance Materials Outlook for 2011

Performance Materials sales are expected to increase across most businesses in 2011 as recovery in the transportation, building and construction, and infrastructure-related industries continues, particularly in emerging geographies. Moderate volume growth is expected, with continued strong demand and the anticipated start-up of propylene oxide production at a consolidated joint venture in Thailand. Dow Formulated Systems volume is expected to continue to grow, with increased demand in energy efficiency and alternative energy applications. The Performance Materials segment expects increased prices in 2011, driven by projected higher feedstock and energy and other raw material costs.

PERFORMANCE PLASTICS

The Performance Plastics segment includes the following businesses: Dow Elastomers; Dow Electrical and Telecommunications; Dow Packaging and Converting; Plastics Licensing and Catalyst; Polyethylene; and Polypropylene. These world-leading businesses provide a broad range of products and solutions by leveraging Dow’s leading manufacturing and application technology, research and product development expertise, extensive market knowledge and strong customer relationships.

2010 Actual Versus 2009 Pro Forma

Performance Plastics sales for 2010 were $15,260 million, up 17 percent from $13,026 million in 2009, with price up 20 percent and volume down 3 percent. Global economic conditions began to improve during the second half of 2009 and this momentum carried over into 2010. Feedstock and energy costs were significantly higher than in 2009, driving double-digit price increases in all geographic areas. The decline in volume for the segment reflected the divestiture of the Styrenics and Polycarbonate and Compounds and Blends businesses as part of the June 17, 2010 divestiture of Styron. Sales volume, excluding the impact of the Styron divestiture, was up 4 percent from 2009. Sales volume during the first half of 2010 was negatively impacted by planned maintenance turnarounds at the Company’s polyethylene and polypropylene production facilities in North America and Europe. Production was also negatively impacted during the first half of the year by an unplanned site outage at the Company’s polypropylene production facility in Schkopau, Germany, and by ethylene supply limitations at the Company’s Bahia Blanca polyethylene facility in Argentina. With the completion of the maintenance

31

turnarounds and resolution of the outages, production returned to normal levels during the second half of 2010 and demand was strong. Polypropylene volume was significantly higher in North America and EMEA as demand in the consumer goods, automotive and packaging sectors was particularly strong. Dow Elastomers reported strong, double-digit volume increases in all geographic areas due to tight supply/demand balances during the year. Dow Packaging and Converting also achieved strong volume increases in all geographic areas as the global economic recovery increased demand for adhesives and other packaging materials.

EBITDA for 2010 was $3,565 million, up from $2,147 million in 2009. While feedstock and energy and other raw materials costs were significantly higher than 2009, the increases were more than offset by higher prices and improved equity earnings from the Company’s joint ventures in Kuwait. EBITDA for 2010 included a $7 million net gain on the divestiture of Styron. EBITDA in 2009 was negatively impacted by $65 million of impairment charges related to the Company’s investment in Equipolymers, a nonconsolidated affiliate; an increase in cost of sales of $53 million related to the fair valuation of Rohm and Haas inventories; and $2 million of restructuring charges. See Note C to the Consolidated Financial Statements for information on restructuring charges.

2009 Versus 2008 (Pro Forma Comparison)

Performance Plastics sales for 2009 were $13,026 million, down 29 percent from $18,435 million in 2008. The decline in feedstock costs and the weak pricing environment that developed in late 2008 carried forward into 2009, resulting in prices that were 23 percent lower than those of 2008. After reaching a low point during the first quarter of 2009, prices improved during the remainder of the year. Volume was negatively impacted by weak global economic conditions, declining 6 percent for the year. Polyethylene and polypropylene volumes improved in Asia Pacific and Latin America and as the economic recovery began to gather momentum, demand increased. Lower natural gas and other feedstock prices in North America, as well as delays in the startup of new Middle East industry production capacity, resulted in economic conditions that favored the export of North American production into these geographic areas. Dow Elastomers and Dow Electrical and Telecommunications volume decreased in all geographic areas, the result of continued weakness in the global automotive and construction industries. Volume was also reduced in North America due to the May 2008 formation of Americas Styrenics LLC.

EBITDA for 2009 was $2,147 million, down from $2,154 million in 2008. While Performance Plastics benefited from a significant decline in feedstock costs, lower raw material and freight costs and lower SG&A expenses, these favorable impacts were more than offset by the decline in prices. Equity earnings were down slightly from 2008 as improved earnings from Americas Styrenics LLC, The Kuwait Olefins Company K.S.C., LG DOW Polycarbonate Limited and Siam Polyethylene were more than offset by lower earnings from EQUATE and $65 million of impairment charges related to the Company’s investment in Equipolymers. EBITDA in 2009 was impacted by an increase in cost of sales of $53 million related to the fair valuation of Rohm and Haas inventories and $2 million of restructuring charges. EBITDA in 2008 was reduced by restructuring charges totaling $183 million, which reflected the write-down of the Company’s investment in a project to form a joint venture in Oman with the Oman Petrochemicals Industries Company LLC; costs related to the shutdown of production facilities (Terneuzen, The Netherlands; Freeport, Texas; Seadrift, Texas; and Riverside, Missouri); as well as costs associated with the permanent shutdown of the operations of the Pétromont and Company, Limited Partnership (“Pétromont”) joint venture in Varennes, Canada. EBITDA in 2008 also included a goodwill impairment loss of $30 million associated with the polypropylene reporting unit (see Note I to the Consolidated Financial Statements), as well as costs of $22 million related to the U.S. Gulf Coast hurricanes.

Performance Plastics Outlook for 2011

Feedstock and energy costs are expected to increase in 2011 as global economic conditions continue to improve. In North America, stable natural gas prices are expected to help U.S. Gulf Coast polyethylene production maintain a competitive position globally. The Company will continue to focus on higher margin, differentiated products and operating efficiencies to minimize the potential impact of higher and volatile propylene costs. Both polyethylene and polypropylene are expected to face increased competition from new industry capacity that came on-line in 2009 and 2010 and additional industry capacity expected to come on-line during 2011. Dow Elastomers is expected to experience continued growth with the introduction of the ENLIGHT™ encapsulant films, which began commercial-scale production in late 2010 in Findlay, Ohio. The segment is also expected to be favorably impacted by projects at the SCG-Dow Group’s facilities in Thailand where a new solutions polyethylene plant came on-line in the fourth quarter of 2010 and the start-up of a new specialty elastomers production train is anticipated to take place in 2011. These facilities will increase capacity and expand the Company's presence in Asia Pacific. Equity earnings from the Company’s joint ventures in Kuwait and Univation Technologies, LLC are also expected to improve in 2011.

FEEDSTOCKS AND ENERGY

The Feedstocks and Energy segment includes the following businesses: Chlor-Alkali/Chlor-Vinyl; Energy; Ethylene Oxide/Ethylene Glycol; and Hydrocarbons. The Chlor-Alkali/Chlor-Vinyl business focuses on the production of chlorine for consumption by downstream Dow derivatives, as well as production, marketing and supply of ethylene dichloride, vinyl chloride monomer and caustic soda. These products are used for applications such as alumina production, pulp and paper manufacturing, soaps and detergents, and building and construction. The Energy business supplies power, steam and other utilities, principally for use in Dow’s global operations. The Ethylene Oxide/Ethylene Glycol business is the world’s largest producer of purified ethylene oxide, principally used in Dow’s downstream performance derivatives. Dow is also a key supplier of ethylene glycol to MEGlobal, a 50:50 joint venture and world leader in the manufacture and marketing of merchant monoethylene glycol and diethylene glycol. Ethylene glycol is used in polyester fiber, polyethylene terephthalate (PET) for food and beverage container applications, polyester film, and aircraft and runway deicers. TheHydrocarbonsbusiness encompasses the procurement of natural gas liquids and crude oil-based raw materials, as well as the supply of monomers, principally for use in Dow's global operations. The business regularly sells its by-products and buys and sells products in order to balance regional production capabilities and derivative requirements. The business also sells products to certain Dow joint ventures. Also included in the Feedstocks and Energy segment are the results of Compañia Mega S.A., MEGlobal and a portion of the results of EQUATE Petrochemical Company K.S.C., The Kuwait Olefins Company K.S.C., and the SGC-Dow Group, all joint ventures of the Company.

On March 2, 2010, Dow announced the entry into a definitive agreement to sell Styron to an affiliate of Bain Capital Partners; the transaction closed on June 17, 2010. Businesses and products sold within the Feedstocks and Energy segment included certain styrene monomer assets, which were reported in the Feedstocks and Energy segment through the date of the divestiture. On September 30, 2009, the Company completed the sale of its ownership interest in the OPTIMAL Group of Companies, nonconsolidated affiliates, to Petroliam Nasional Berhad; a portion of the results were reported in the Feedstocks and Energy segment through the date of the divestiture. See Note E to the Consolidated Financial Statements for additional information on these divestitures.

For the Feedstocks and Energy segment, there was no difference between actual and pro forma sales and EBITDA for 2009 and 2008.

2010 Versus 2009

Feedstocks and Energy sales were $8,457 million in 2010, up 33 percent from $6,346 million in 2009. Compared with last year, price was up 28 percent, with increases reported across all businesses and geographic areas. Volume improved 5 percent for the segment, as volume gains in the Hydrocarbons, Chlor-Alkali/Chlor-Vinyl and Energy businesses more than offset declines in the Ethylene Oxide/Ethylene Glycol (“EO/EG”) business. Excluding divestitures, volume improved 23 percent. Sales for the Hydrocarbons business were up 40 percent with prices increasing 35 percent and volume increasing 5 percent. The increase in selling prices for the Hydrocarbons business was a result of higher feedstock and energy costs, driven by demand improvement across the industry, while product supply agreements with Styron led to an increase in trade sales volume compared with 2009. Sales for the Chlor-Alkali/Chlor-Vinyl business increased 28 percent over 2009, driven by a 19 percent increase in price and 9 percent increase in volume. Within the business, vinyl chloride monomer (“VCM”) price and volume increased in response to higher ethylene costs and strong U.S. polyvinyl chloride (“PVC”) export demand, and caustic soda volume improved due to increased demand in the alumina and pulp and paper industries. Sales for the EO/EG business were down compared with 2009, as a 21 percent decrease in volume more than offset a 19 percent increase in price. EO/EG volume declined as expected, due to the business’ strategic shift to supply purified ethylene oxide to internal derivative businesses, and the closure of the Company’s Wilton, England facility in January 2010.Sales for the Energy business increased 34 percent compared with 2009, with volume up 31 percent and price up 3 percent. Sales for the Energy business are primarily opportunistic merchant sales driven by market conditions and sales to customers located on Dow manufacturing sites. Sales fluctuate as the Company

33

balances energy supply and demand at its manufacturing sites; however, the improving economy offered more opportunities for merchant sales in 2010.

The Company uses derivatives of crude oil and natural gas as feedstock in its ethylene facilities. The Company's cost of purchased feedstock and energy increased $5.0 billion in 2010. Crude oil prices increased, and on average, 2010 prices were $18 per barrel (29 percent) higher than 2009 levels. North American natural gas prices also increased in 2010, and were approximately $0.50 per million Btu higher than in 2009, an increase of 13 percent.

The Hydrocarbons business transfers materials to Dow's derivative businesses and the Energy business supplies utilities to Dow’s businesses at net cost, resulting in EBITDA that is at or near break-even for both businesses. For the segment, EBITDA for 2010 was $471 million, down slightly from $477 million in 2009, which included a $457 million gain on the sale of the Company's ownership interest in TRN and a $193 million gain on the sale of the Company’s ownership interest in OPTIMAL partially offset by $140 million of restructuring costs (see Note C to the Consolidated Financial Statements for information on restructuring charges). EBITDA in 2010 was impacted by higher prices and volume, improved operating rates and higher equity earnings from EQUATE, MEGlobal and The Kuwait Olefins Company K.S.C.

2009 Versus 2008

Feedstocks and Energy sales were $6,346 million in 2009, down 50 percent from $12,781 million in 2008. Both volume and prices were down across all businesses, primarily due to unfavorable supply/demand balances. Hydrocarbons sales were down 53 percent, the result of a 28 percent decrease in price and a 25 percent drop in volume. The decrease in selling prices in 2009 was driven by the impact of the global economic recession and the unprecedented decline of crude oil and other commodity prices that began in the fourth quarter of 2008 and continued into 2009. Volume declined sharply in 2009 due to lower ethylene cracker operating rates and lower refinery sales as a result of a planned maintenance and turnaround at TRN and the September 1, 2009 sale of the Company's ownership interest in TRN. Chlor-Alkali/Chlor-Vinyl sales decreased 41 percent compared with 2008, with a 33 percent decrease in prices and an 8 percent decrease in volume. Prices for VCM were down compared with 2008 on weak demand in the housing and construction industries; volume was essentially unchanged as increased sales to customers exporting polyvinyl chloride offset the decline in North American domestic demand. Caustic soda sales were impacted by weak demand in the alumina, chemical processing and pulp and paper industries, driving both prices and volume down. Sales for the EO/EG business decreased 55 percent versus 2008, with a 32 percent decrease in volume and a 23 percent decrease in prices, as EG volume declined due to pressure from new industry capacity, and prices declined due to lower ethylene prices and weak demand.

The Company's cost of purchased feedstock and energy declined $10.2 billion (40 percent) in 2009. Crude oil prices decreased, and on average, 2009 prices were $36 per barrel (37 percent) lower than 2008 levels. North American natural gas prices also decreased significantly, and were approximately $5.04 per million Btu lower than in 2008, a decrease of 56 percent.

EBITDA for 2009 was $477 million, compared with $207 million in 2008. EBITDA for 2009 was positively impacted by a $457 million gain on the sale of the Company's ownership interest in TRN, a $193 million gain on the sale of the Company’s ownership interest in OPTIMAL, offset by $140 million of restructuring costs. EBITDA in 2008 was negatively impacted by hurricane-related costs of $69 million and $84 million of restructuring charges related to the impairment or closure of several manufacturing facilities and (see Note C to the Consolidated Financial Statements for information on restructuring charges).

Feedstocks and Energy Outlook for 2011

The Feedstocks and Energy segment expects overall market conditions to be consistent with 2010. Crude oil and feedstocks are expected to remain volatile and sensitive to external factors such as economic activity and geopolitical tensions. In 2011, the Company expects crude oil prices, on average, to be higher than 2010. Demand is expected to grow in line with, or above, gross domestic product. Ethylene margins are expected to fluctuate due to variability in economic recovery and new industry capacity. VCM sales are expected to decline in 2011 due to the Company’s planned reduction of North American VCM production capacity. Additional chlor-alkali industry capacity is expected to come on-line during the second half of 2011, but increasing global demand should keep supply and demand consistent with 2010. The EO/EG business is completing a strategic shift to produce purified EO for the internal Dow derivative businesses; this will result in lower sales volume in 2011.

In the fourth quarter of 2010, Dow and Mitsui & Co., Ltd. formed a 50:50 manufacturing joint venture to construct, own and operate a new membrane chlor-alkali facility located at Dow’s Freeport, Texas, integrated manufacturing complex. Construction is slated to begin in early 2011, and operations are expected to begin in mid-2013. The new facility will have an annual capacity of approximately 800 kilotons. Under contract to the joint venture, Dow will operate and maintain the facility and the joint venture is consolidated into Dow’s consolidated financial statements.

2010 Actual Versus 2009 Pro Forma

Sales for Corporate, which for 2010 primarily related to the Company’s insurance operations, were $332 million in 2010, down from $1,083 million in 2009, which also included the sales of Morton International, Inc. (“Morton,” the Salt business acquired with the Rohm and Haas acquisition) through the fourth quarter of 2009 divestiture of the business.

EBITDA for 2010 was a loss of $1,472 million, compared with a loss of $1,127 million in the same period last year.EBITDA for 2010 was lower due to increased performance-based compensation (including stock-based compensation and increased expense related to higher employee participation in the Employees’ Stock Purchase Plan) and the absence of earnings from Morton. Additionally, EBITDA was reduced by integration costs of $143 million related to the acquisition of Rohm and Haas, $50 million of labor-related litigation costs, a charge of $47 million for an obligation related to a past divestiture, and a $46 million loss on the early extinguishment of debt. EBITDA for 2010 was favorably impacted by a $54 million reduction in the asbestos-related liability and $2 million in net adjustments to prior year restructuring plans.

EBITDA for 2009 was reduced by costs related to the April 1, 2009 acquisition of Rohm and Haas of $362 million, including $166 million of other transaction and integration costs expensed in accordance with the accounting guidance for business combinations, $60 million of acquisition-related retention expenses, a $56 million loss on the early extinguishment of debt, and $80 million of transaction and other acquisition costs incurred by Rohm and Haas prior to the April 1, 2009 acquisition. EBITDA was also impacted by $224 million of 2009 restructuring charges, including employee-related severance expenses of $155 million, environmental obligations of $64 million, and $5 million of asset write-offs; plus $28 million in adjustments related to prior year restructuring plans. EBITDA for 2009 was further reduced by $7 million of IPR&D write-offs and $2 million of costs related to the 2008 hurricanes.

2009 Versus 2008 (Pro Forma Comparison)

Sales for Corporate, which for 2009 and 2008 primarily related to Morton and the Company’s insurance operations, were $1,083 million in 2009, down from $1,525 million in 2008, reflecting the fourth quarter 2009 divestiture of Morton.

EBITDA for 2009 was a loss of $1,127 million, compared with a loss of $1,089 million in 2008. EBITDA for 2009 was reduced by costs related to the April 1, 2009 acquisition of Rohm and Haas of $362 million, $224 million of 2009 restructuring charges, $28 million in adjustments related to prior year restructuring plans, $7 million of IPR&D write-offs, and $2 million of costs related to the 2008 hurricanes.

EBITDA for 2008 was negatively impacted by $594 million of 2008 restructuring charges, including employee-related severance expense of $321 million, pension curtailment costs and termination benefits of $88 million, asset write-offs and environmental obligations of $21 million, Rohm and Haas restructuring charges of $162 million and net adjustments to prior year restructuring plans of $2 million. EBITDA for 2008 was also negatively impacted by legal expenses and other costs related to the K-Dow transaction of $69 million and the acquisition of Rohm and Haas of $103 million; and costs associated with the U.S. Gulf Coast hurricanes of $18 million. EBITDA for 2008 was favorably impacted by a $54 million reduction in the asbestos-related liability.

LIQUIDITY AND CAPITAL RESOURCES

The Company’s cash flows from operating, investing and financing activities, as reflected in the Consolidated Statements of Cash Flows, are summarized in the following table:

Cash Flow Summary In millions	2010			2009			2008
Cash provided by (used in):
Operating activities	$	4,102		$	2,075		$	4,711
Investing activities	135			(14,767		)	(2,737		)
Financing activities	(178		)	12,659			(978		)
Effect of exchange rate changes on cash	88			79			68
Cash assumed in initial consolidation of variable interest entities	46			—			—
Net increase in cash and cash equivalents	$	4,193		$	46		$	1,064

Cash provided by operating activities in 2010 increased significantly compared with 2009 primarily due to increased earnings. Cash provided by operating activities in 2009 declined compared with 2008 due to an increase in working capital requirements primarily driven by an increase in trade accounts receivable. The increase in trade accounts receivable reflected the increase in sales toward the end of 2009 versus the end of 2008 primarily due to the acquisition of Rohm and Haas in 2009.

Cash provided by investing activities in 2010 reflected proceeds from the divestiture of Styron, as well as other smaller divestitures, proceeds from the change in restricted cash related to the consolidation of a variable interest entity (see Note S to the Consolidated Financial Statements) and the usage of cash for capital expenditures. Cash used in investing activities in 2009 increased over 2008, reflecting the April 1, 2009 acquisition of Rohm and Haas for $15,681 million and the purchase of a previously leased ethylene plant in Canada for $713 million, partially offset by the proceeds from the sale of the Company’s interest in nonconsolidated affiliates (TRN for $742 million and OPTIMAL for $660 million), net proceeds from the sale of Morton ($1,576 million) and lower capital expenditures.

Cash used in financing activities in 2010 included payments on long-term debt and commercial paper, payments on notes payable related to the monetization of accounts receivable in Europe, and the payment of dividends to stockholders, partially offset by the proceeds from issuance of long-term debt. Cash provided by financing activities increased significantly in 2009, reflecting the funding for the acquisition of Rohm and Haas as discussed in further detail below, partially offset by the redemption of the preferred partnership units and accrued dividends of Tornado Finance V.O.F. of $520 million.

Management expects that the Company will continue to have sufficient liquidity and financial flexibility to meet all of its business obligations.

The Company has undertaken several restructuring plans during the past three years as follows:

• On December 5, 2008, the Board of Directors approved a restructuring plan (the “2008 Plan”) that included the shutdown of a number of facilities and a global workforce reduction. At the end of 2010, these restructuring activities were substantially complete with remaining liabilities primarily related to pension and environmental remediation to be paid over time.

• Included in the liabilities assumed with the April 1, 2009 acquisition of Rohm and Haas was a reserve of $122 million for severance and employee benefits for the separation of 1,255 employees associated with Rohm and Haas’ 2008 restructuring initiatives. The separations resulted from plant shutdowns, production schedule adjustments, productivity improvements and reductions in support services. These restructuring activities are scheduled to be completed primarily by the third quarter of 2011.

• On June 30, 2009, following the acquisition of Rohm and Haas, the Board of Directors approved a restructuring plan (the “2009 Plan”) that includes the elimination of approximately 2,500 positions and the shutdown of a number of manufacturing facilities. These restructuring activities are scheduled to be completed primarily by the end of 2011.

The restructuring activities related to the 2008 Plan, the severance reserve assumed from Rohm and Haas and the 2009 Plan are expected to result in additional cash expenditures of approximately $240 million related to severance costs, contract termination fees, asbestos abatement and environmental remediation (see Note C to the Consolidated Financial Statements). The Company expects to incur future costs related to its restructuring activities, as the Company continually looks for ways to

38

enhance the efficiency and cost effectiveness of its operations to ensure competitiveness across its businesses and across geographic areas. Future costs are expected to include demolition costs related to the closed facilities, which will be recognized as incurred. The Company also expects to incur additional employee-related costs, including involuntary termination benefits and pension plan settlement costs, related to its other optimization activities. These costs cannot be reasonably estimated at this time.

Working Capital at December 31  In millions	2010		2009
Current assets	$	24,130	$	19,542
Current liabilities	13,896		13,105
Working capital	$	10,234	$	6,437
Current ratio	1.74:1		1.49:1

Working capital increased from December 31, 2009 to December 31, 2010 principally due to increased cash and cash equivalents. At December 31, 2010, trade receivables were $4.6 billion, down from $5.7 billion at December 31, 2009, primarily due to a change in the way the sale of accounts receivable facilities are being recorded (see Note O to the Consolidated Financial Statements), as well as the divestiture of Styron (see Note E to the Consolidated Financial Statements). Days-sales-outstanding-in-receivables (excluding the impact of sales of receivables) was 43 days at December 31, 2010 compared with 45 days at December 31, 2009. At December 31, 2010, total inventories were $7.1 billion, up from $6.8 billion at December 31, 2009. Days-sales-in-inventory at December 31, 2010 was 62 days versus 64 days at December 31, 2009.

At the end of 2009, the Company’s net debt as a percent of total capitalization had risen to 48.0 percent, due to increased financing related to the acquisition of Rohm and Haas. As shown in the following table, net debt is equal to total debt minus “Cash and cash equivalents.” As Dow continues to strengthen its balance sheet and increase financial flexibility, management is principally focused on net debt, as Dow believes this is the best measure of the Company’s financial leverage. By the end of 2010, net debt as a percent of total capitalization had been reduced to 42.6 percent.

Total Debt at December 31  In millions	2010			2009
Notes payable	$	1,467		$	2,139
Long-term debt due within one year	1,755			1,082
Long-term debt	20,605			19,152
Gross debt	$	23,827		$	22,373
Cash and cash equivalents	$	7,039		$	2,846
Net debt	$	16,788		$	19,527
Gross debt as a percent of total capitalization	51.3		%	51.4		%
Net debt as a percent of total capitalization	42.6		%	48.0		%

Financing Activities

As part of its ongoing financing activities, Dow has the ability to issue promissory notes under its U.S. and Euromarket commercial paper programs. At December 31, 2010, the Company had no commercial paper outstanding. Through January 2011, the Company maintained access to the commercial paper market at competitive rates.

In the event Dow has short-term liquidity needs and is unable to issue commercial paper under these programs for any reason, Dow has the ability to access liquidity through its committed and available $3 billion Three Year Competitive Advance and Revolving Credit Facility Agreement dated June 4, 2010 (the “Revolving Credit Facility”) with various U.S. and foreign banks. The Revolving Credit Facility has a maturity date in June 2013 and provides for interest at a LIBOR-plus rate or Base Rate as defined in the Agreement. The Revolving Credit Facility replaces the previous facility dated April 24, 2006. On March 9, 2009, the Company borrowed $3 billion under the previous facility, and the Company used the funds to finance its day-to-day operations, to repay indebtedness maturing in the ordinary course of business and for other general corporate purposes. At December 31, 2009, all outstanding balances had been repaid. At December 31, 2010, the full $3 billion Revolving Credit Facility was available to the Company.

39

As a well-known seasoned issuer, the Company filed an automatic shelf registration for an unspecified amount of mixed securities with the SEC on February 19, 2010. Under this shelf registration, the Company may offer common stock, preferred stock, depositary shares, debt securities, warrants, stock purchase contracts and stock purchase units with pricing and availability dependent on market conditions; and, on February 19, 2010, registered an unlimited amount of securities for issuance under the Company’s U.S. retail medium-term note program (InterNotes). At December 31, 2010, the Company had Euro 5 billion (approximately $6.7 billion) available for issuance under the Company’s Euro Medium Term Note Program, as well as Japanese yen 50 billion (approximately $600 million) of securities available for issuance under a shelf registration renewed with the Tokyo Stock Exchange effective September 8, 2010, which will expire on September 7, 2012.

During 2010, the Company issued $537 million in InterNotes with varying maturities in 2015, 2017 and 2020, at various interest rates averaging 4.70 percent.

On September 8, 2010, the Company concluded a tender offer for any and all of $145 million of debentures acquired from Rohm and Haas, due June 2020. As a result of the tender offer, the Company redeemed $123 million of the debentures and recognized a $46 million pretax loss on this early extinguishment, included in “Sundry income – net.”

On November 4, 2010, the Company issued $2.5 billion of debt securities in a public offering. The offering included $750 million aggregate principal amount of 2.50 percent notes due 2016 and $1.75 billion aggregate principal amount of 4.25 percent notes due 2020.

On June 4, 2009, the preferred partner of Tornado Finance V.O.F., a consolidated foreign subsidiary of the Company, notified Tornado Finance V.O.F. that the preferred partnership units would be redeemed in full on July 9, 2009 as permitted by the terms of the partnership agreement. On July 9, 2009, the preferred partnership units and accrued dividends were redeemed for a total of $520 million. See Note V to the Consolidated Financial Statements.

On August 21, 2009, the Company executed a buy-back of Euro 175 million of private placement debt acquired from Rohm and Haas and recognized a $56 million pretax loss on early extinguishment, included in “Sundry income – net.”

Between May and December 2009, the Company issued $640 million in InterNotes with varying maturities in 2014, 2016 and 2019, at various interest rates averaging 6.45 percent.

Dow’s public debt instruments and documents for its private funding transactions contain, among other provisions, certain covenants and default provisions. The Company’s most significant debt covenant with regard to its financial position is the obligation to maintain the ratio of the Company’s consolidated indebtedness to consolidated capitalization at no greater than 0.65 to 1.00 at any time the aggregate outstanding amount of loans under the Revolving Credit Facility exceeds $500 million. The ratio of the Company’s consolidated indebtedness to consolidated capitalization as defined in the credit agreements was 0.493 to 1.00 at December 31, 2010. At December 31, 2010, management believes the Company was in compliance with all covenants and default provisions. For information on Dow’s covenants and default provisions, see Note P to the Consolidated Financial Statements.

The Company’s credit rating is investment grade. The Company’s long-term credit ratings are BBB- with a positive outlook (Standard & Poor’s), Baa3 with a stable outlook (Moody’s) and BBB with a stable outlook (Fitch). In the third quarter of 2010, Standard & Poor’s upgraded the Company’s outlook from stable to positive, and in the fourth quarter of 2010, Moody’s upgraded the Company’s outlook from negative to stable. The Company’s short-term credit ratings are A-3 (Standard & Poor’s), P-3 (Moody’s) and F2 (Fitch). If the Company’s credit ratings are downgraded, borrowing costs will increase on certain indentures, and it could have a negative impact on the Company’s ability to access credit markets.

Financing Activities Related to the Acquisition of Rohm and Haas

On April 1, 2009, the Company completed the acquisition of Rohm and Haas. Pursuant to the July 10, 2008 Agreement and Plan of Merger (the “Merger Agreement”), Ramses Acquisition Corp., a direct wholly owned subsidiary of the Company, merged with and into Rohm and Haas (the “Merger”), with Rohm and Haas continuing as the surviving corporation and a direct wholly owned subsidiary of the Company. Financing for the April 1, 2009 transaction included debt of $9.2 billion obtained through a Term Loan Agreement (“Term Loan”), as well as equity investments by Berkshire Hathaway Inc. (“BHI”) and the Kuwait Investment Authority (“KIA”) in the form of Cumulative Convertible Perpetual Preferred Stock, Series A of 3 million shares for $3 billion (BHI) and 1 million shares for $1 billion (KIA).

40

In connection with the closing of the Merger, the Company entered into an Investment Agreement with certain trusts established by members of the Haas family (the “Haas Trusts”) and Paulson & Co. Inc. (“Paulson”), each of whom was a significant shareholder of Rohm and Haas common stock at the time of the Merger. Under the Investment Agreement, the Haas Trusts and Paulson purchased from the Company 2.5 million shares (Haas Trusts - 1.5 million shares; Paulson - 1.0 million shares) of Cumulative Perpetual Preferred Stock, Series B (“preferred series B”) for an aggregate price of $2.5 billion, with $1.5 billion from the Haas Trusts and $1.0 billion from Paulson. The Haas Trusts made an additional investment in 0.5 million shares of Cumulative Convertible Perpetual Preferred Stock, Series C (“preferred series C”) for an aggregate price of $500 million.

In May 2009, the Company entered into a purchase agreement with the Haas Trusts and Paulson, whereby the Haas Trusts and Paulson agreed to sell to the Company their shares of the preferred series B in consideration for shares of the Company’s common stock and/or notes at the discretion of the Company.

On May 6, 2009, the Company launched a public offering of 150.0 million shares of its common stock. Included in the 150.0 million shares offered to the public were 83.3 million shares issued to the Haas Trusts and Paulson in a private transaction in consideration for 1.2 million shares of preferred series B, at par plus accrued dividends, held by the Haas Trusts and Paulson. Gross proceeds were $2,250 million, of which the Company’s net proceeds (after underwriting discounts and commissions) were $966 million for the sale of the Company’s 66.7 million shares.

On May 7, 2009, the Company issued $6 billion of debt securities in a public offering. The offering included $1.75 billion aggregate principal amount of 7.6 percent notes due 2014; $3.25 billion aggregate principal amount of 8.55 percent notes due 2019; and $1 billion aggregate principal amount of 9.4 percent notes due 2039. An aggregate principal amount of $1.35 billion of the 8.55 percent notes due 2019 were offered by accounts and funds managed by Paulson and the Haas Trusts. These investors received notes from the Company in payment for 1.3 million shares of preferred series B, at par plus accrued dividends. The Company used the net proceeds received from this offering for refinancing, renewals, replacements and refunding of outstanding indebtedness, including repayment of a portion of the Term Loan.

Upon the consummation of the above transactions, all shares of preferred series B were retired.

On May 26, 2009, the Company entered into an underwriting agreement and filed the corresponding shelf registration statement to effect the conversion of preferred series C into the Company’s common stock. On June 9, 2009, following the end of the sale period and determination of the share conversion amount, the Company issued 31.0 million shares of common stock to the Haas Trusts and all shares of preferred series C were retired.

On August 4, 2009, the Company issued $2.75 billion of debt securities in a public offering. The offering included $1.25 billion aggregate principal amount of 4.85 percent notes due 2012; $1.25 billion aggregate principal amount of 5.90 percent notes due 2015; and $0.25 billion aggregate principal amount of floating rate notes due 2011. The Company used the net proceeds received from this offering for refinancing, renewals, replacements and refunding of outstanding indebtedness, including repayment of a portion of the Term Loan.

On October 1, 2009, the remaining balance of the Term Loan was fully repaid using proceeds from the sale of the Salt business. See Note E to the Consolidated Financial Statements for more information on the divestiture of the Salt business.

See Notes D, P, W and X to the Consolidated Financial Statements for more information on the acquisition of Rohm and Haas and the corresponding financing activities.

Capital Expenditures

Capital spending for the year was $2,130 million (including $548 million of capital spending by consolidated variable interest entities); see Note B to the Consolidated Financial Statements for information on variable interest entities consolidated at January 1, 2010. Capital spending in 2009 was $1,683 million (including $273 million of capital spending by a consolidated variable interest entity); see Note S to the Consolidated Financial Statements for information on a variable interest entity consolidated in 2009. Capital spending in 2008 was $2,276 million. In 2010, approximately 39 percent of the Company’s capital expenditures were directed toward additional capacity for new and existing products, compared with 43 percent in 2009 and 40 percent in 2008. In 2010, approximately 17 percent was committed to projects related to environmental protection, safety, loss prevention and industrial hygiene compared with 20 percent in 2009 and 18 percent in 2008. The remaining capital was utilized to maintain the Company’s existing asset base, including projects related to productivity improvements, energy conservation and facilities support.

41

Major projects underway during 2010 included: construction of a new propylene oxide production facility using hydrogen peroxide to propylene oxide technology, a distribution terminal and related infrastructure and utilities in Thailand; conversion of the St. Charles, Louisiana facility to produce only ethylene oxide to support the Company’s business strategy to supply purified ethylene oxide to internal derivative customers; the design and construction of a new chlor-alkali production facility to replace existing facilities in Freeport, Texas; the installation of two new steam boilers in Stade, Germany; and the enhancement of caustic production assets in Freeport, Texas. Additional major projects included construction of a storage cavern for feedstock supply in Canada; new area headquarters and laboratory facilities in Brazil; new brine wells in Brazil; furnace rehabilitations to increase energy utilization in ethylene production at St. Charles, Louisiana; a new centrifugal ethylene compressor in Freeport, Texas to reduce spot purchases of ethylene; and the design and construction of the new Midland Business Process Service Center. Because the Company designs and builds most of its capital projects in-house, it had no material capital commitments other than for the purchase of materials from fabricators and construction labor. The Company expects capital spending in 2011 to be approximately $2.4 billion.

Contractual Obligations

The following tables summarize the Company’s contractual obligations, commercial commitments and expected cash requirements for interest at December 31, 2010. Additional information related to these obligations can be found in Notes N, P, Q, R and Y to the Consolidated Financial Statements.

Contractual Obligations at December 31, 2010	Payments Due by Year

(1) Excludes unamortized debt discount of $458 million.

(2) Deferred income tax liabilities may vary according to changes in tax laws, tax rates and the operating results of the Company. As a result, it is impractical to determine whether there will be a cash impact to an individual year. All noncurrent deferred income tax liabilities have been reflected in “2016 and beyond.”

(3) Annual payments to resolve asbestos litigation will vary based on changes in defense strategies, changes in state and national law, and claims filing and resolution rates. As a result, it is impractical to determine the anticipated payments in any given year. Therefore, the majority of the noncurrent asbestos-related liability of $663 million has been reflected in “2016 and beyond.”

(4) Due to uncertainties in the timing of the effective settlement of tax positions with the respective taxing authorities, the Company is unable to determine the timing of payments related to its uncertain tax positions, including interest and penalties. Amounts beyond the current year are therefore reflected in “2016 and beyond.”

(5) Includes outstanding purchase orders and other commitments greater than $1 million, obtained through a survey conducted within the Company.

Off-Balance Sheet Arrangements

On January 1, 2010, the Company adopted ASU 2009-17, “Consolidations (Topic 810): Improvements to Financial Reporting by Enterprises Involved with Variable Interest Entities.” ASU 2009-17 amends the consolidation guidance applicable to variable interest entities (“VIEs”) and requires additional disclosures concerning an enterprise’s continuing involvement with VIEs. The Company evaluated the impact of this guidance and determined that the adoption resulted in the January 1, 2010 consolidation of two additional joint ventures, an owner trust and an entity that was used to monetize accounts receivable. The Company also holds a variable interest in another joint venture accounted for under the equity method of accounting. The Company is not the primary beneficiary of the joint venture and therefore is not required to consolidate this entity. See Notes B and S to the Consolidated Financial Statements.

42

Guarantees arise during the ordinary course of business from relationships with customers and nonconsolidated affiliates when the Company undertakes an obligation to guarantee the performance of others if specific triggering events occur. The Company had outstanding guarantees at December 31, 2010 of $836 million, down from $1,053 million at December 31, 2009. The decrease in maximum future payments from year-end 2009 was due to the consolidation of the Company’s variable interest in an owner trust in the first quarter of 2010, with the adoption of ASU 2009-17 (see Notes B and S to the Consolidated Financial Statements). Additional information related to these guarantees can be found in the “Guarantees” section of Note N to the Consolidated Financial Statements.

See Note O to the Consolidated Financial Statements for information regarding the impact of adopting ASU 2009-16, “Transfers and Servicing (Topic 860): Accounting for Transfers of Financial Assets,” on January 1, 2010 and for additional information regarding the transfer of financial assets.

Fair Value Measurements

The Company’s assets and liabilities measured at fair value are classified in the fair value hierarchy (Level 1, 2 or 3) based on the inputs used for valuation. Assets and liabilities that are traded on an exchange with a quoted price are classified as Level 1. Assets and liabilities that are valued based on a bid or bid evaluation are classified as Level 2. The custodian of the Company’s debt and equity securities uses multiple industry-recognized vendors for pricing information and established processes for validation and verification to assist the Company in its process for determining and validating fair values for these assets. For pension or other post retirement benefit plan assets classified as Level 3, the total fair value is based on significant unobservable inputs including assumptions where there is little, if any, market activity for the investment. The sensitivity of fair value estimates is immaterial relative to the assets and liabilities measured at fair value, as well as to the total equity of the Company. See Note K to the Consolidated Financial Statements for the Company’s disclosures about fair value measurements.

Portfolio managers and external investment managers regularly review all of the Company’s holdings to determine if any investments are other-than-temporarily impaired. The analysis includes reviewing the amount of the temporary impairment, as well as the length of time it has been impaired. In addition, specific guidelines for each instrument type are followed to determine if an other-than-temporary impairment has occurred. For debt securities, the credit rating of the issuer, current credit rating trends and the trends of the issuer’s overall sector are considered in determining whether unrealized losses represent an other-than-temporary impairment. For equity securities, the Company’s investments are primarily in Standard & Poor’s (“S&P”) 500 companies; however, the Company also allows investments in companies outside of the S&P 500. The Company considers the evidence to support the recovery of the cost basis of a security including volatility of the stock, the length of time the security has been in a loss position, value and growth expectations, and overall market and sector fundamentals, as well as technical analysis, in determining impairment. In 2010, other-than-temporary impairment write-downs were $5 million ($93 million in 2009).

Dividends

On December 8, 2010, the Board of Directors declared a quarterly dividend of $0.15 per share, payable January 28, 2011, to stockholders of record on December 31, 2010. On February 9, 2011, the Board of Directors declared a quarterly dividend of $0.15 per share, payable April 29, 2011, to stockholders of record on March 31, 2011. Since 1912, the Company has paid a cash dividend every quarter and, in each instance prior to February 12, 2009, had maintained or increased the amount of the dividend, adjusted for stock splits. During this 97-year period, Dow has increased the amount of the quarterly dividend 47 times (approximately 12 percent of the time), and maintained the amount of the quarterly dividend approximately 88 percent of the time. The dividend was reduced in February 2009, for the first time in the 97-year period, due to uncertainty in the credit markets, unprecedented lower demand for chemical products and the ongoing global recession. The Company declared dividends of $0.60 per share in 2010, $0.60 per share in 2009 and $1.68 per share in 2008.

On December 8, 2010, the Board of Directors declared a quarterly dividend of $85 million to Cumulative Convertible Perpetual Preferred Stock, Series A shareholders of record on December 15, 2010, which was paid on January 3, 2011. On February 9, 2011, the Board of Directors declared a quarterly dividend of $85 million to these shareholders, payable on April 1, 2011. Ongoing dividends related to Cumulative Convertible Perpetual Preferred Stock, Series A will accrue at the rate of $85 million per quarter, and are payable quarterly subject to Board of Directors’ approval.

Outlook for 2011

In 2010, Dow and the chemical industry as a whole experienced another year of improving economic conditions. Economies across much of the developed world showed signs of ongoing recovery in most end-markets as the year progressed. Meanwhile, the emerging geographies continued to lead in economic growth and, as a result, were a critical area of focus for new business opportunities and investments. As the year came to a close, however, some challenges remained, such as high unemployment in developed geographies and weakness in construction end-markets, particularly in the United States and Europe. In the face of these challenges, Dow delivered a reshaped and transformed business portfolio in 2010 - one that is increasingly targeted to growing geographic areas and end-markets, and well-balanced to mitigate uncertainties. Furthermore, the Company continued to emphasize its commitment to financial discipline, completing capital market transactions and divesting non-core assets to reduce financial expense and strengthen its balance sheet.

Looking to 2011, Dow expects growth in the emerging geographies to continue, driven by a broad range of leading end-markets. The Company projects that these geographic areas will continue their high rate of growth, although year-over-year comparisons will be subdued relative to recent years. Signs of improvement in industrial end-markets in North America and Europe, coupled with ongoing strength in higher-growth sectors such as electronics, agriculture and packaging, give Dow greater optimism that growth will continue in the developed geographies. Despite these more favorable business conditions, the Company expects lingering challenges to remain, particularly slow employment growth in developed geographies. Furthermore, amid an environment of improving economic conditions, Dow expects feedstock and energy costs to remain at elevated levels, and volatility in these costs to continue. Within the chemical industry, the growing supply of natural gas liquids is expected to continue to benefit the competitiveness of U.S. chemical assets. Meanwhile, the start-up of new ethylene capacity outside of the United States and Europe remains a challenge to supply fundamentals across the ethylene chain and could put downward pressure on the profitability of higher-cost production assets within the industry.

The Company will continue to implement its strategic transformation while remaining focused on strengthening its balance sheet and preferentially investing in its Performance businesses and in emerging geographies. The Company’s plans do not assume an accelerated rebound in business conditions. Rather, Dow’s success will continue to be driven by its transformed business portfolio, balanced geographic presence, and continued investments in innovations aimed at the intersection of greatest societal need and business opportunity.

The Company expects to generate positive cash flow from operations in 2011. Capital spending is expected to increase approximately $300 million from 2010 levels. Research and development spending is projected to remain at approximately the same level as 2010. Equity in earnings of Dow’s nonconsolidated affiliates is expected to improve above pre-recession levels, driven by robust fundamentals at the Company’s principal joint ventures, particularly Dow Corning, EQUATE and The Kuwait Olefins Company K.S.C.

Recent Accounting Guidance

See Note B to the Consolidated Financial Statements for a summary of recent accounting guidance.

Critical Accounting Policies

The preparation of financial statements and related disclosures in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make judgments, assumptions and estimates that affect the amounts reported in the consolidated financial statements and accompanying notes. Note A to the Consolidated Financial Statements describes the significant accounting policies and methods used in the preparation of the consolidated financial statements. Following are the Company’s critical accounting policies impacted by judgments, assumptions and estimates:

Litigation

The Company is subject to legal proceedings and claims arising out of the normal course of business. The Company routinely assesses the likelihood of any adverse outcomes to these matters, as well as ranges of probable losses. A determination of the amount of the reserves required, if any, for these contingencies is made after thoughtful analysis of each known claim. Dow has an active risk management program consisting of numerous insurance policies secured from many carriers. These policies provide coverage that is utilized to minimize the financial impact, if any, of the legal proceedings. The required reserves may change in the future due to new developments in each matter. For further discussion, see Note N to the Consolidated Financial Statements.

Asbestos-Related Matters of Union Carbide Corporation

Union Carbide Corporation (“Union Carbide”), a wholly owned subsidiary of the Company, and a former Union Carbide subsidiary, Amchem Products, Inc. (“Amchem”), are and have been involved in a large number of asbestos-related suits filed primarily in state courts during the past three decades. Based on a study completed by Analysis, Research & Planning Corporation (“ARPC”) in January 2003, Union Carbide increased its December 31, 2002 asbestos-related liability for pending and future claims for the 15-year period ending in 2017 to $2.2 billion, excluding future defense and processing costs. Union Carbide also increased the receivable for insurance recoveries related to its asbestos liability to $1.35 billion at December 31, 2002. Since then, Union Carbide has compared current asbestos claim and resolution activity to the results of the most recent ARPC study at each balance sheet date to determine whether the asbestos-related liability continues to be appropriate. In addition, Union Carbide has requested ARPC to review Union Carbide’s historical asbestos claim and resolution activity each November since 2004 to determine the appropriateness of updating the most recent ARPC study.

In November 2010, Union Carbide requested ARPC to review Union Carbide’s historical asbestos claim and resolution activity and determine the appropriateness of updating its then most recent study completed in December 2008. In response to that request, ARPC reviewed and analyzed data through October 31, 2010. The resulting study, completed by ARPC in December 2010, stated that the undiscounted cost of resolving pending and future asbestos-related claims against Union Carbide and Amchem, excluding future defense and processing costs, through 2025 was estimated to be between $744 million and $835 million. As in its earlier studies, ARPC provided estimates for a longer period of time in its December 2010 study, but also reaffirmed its prior advice that forecasts for shorter periods of time are more accurate than those for longer periods of time.

In December 2010, based on ARPC’s December 2010 study and Union Carbide’s own review of asbestos claim and resolution activity, Union Carbide decreased its asbestos-related liability for pending and future claims to $744 million. The reduction was $54 million and is shown as “Asbestos-related credits” in the consolidated statements of income. At December 31, 2010, the asbestos-related liability for pending and future claims was $728 million.

Union Carbide’s receivable for insurance recoveries related to its asbestos liability was $50 million at December 31, 2010. At December 31, 2010, all of the receivable for insurance recoveries was related to insurers that are not signatories to the Wellington Agreement and/or do not otherwise have agreements in place regarding their asbestos-related insurance coverage.

The amounts recorded by Union Carbide for the asbestos-related liability and related insurance receivable were based upon current, known facts. However, future events, such as the number of new claims to be filed and/or received each year, the average cost of disposing of each such claim, coverage issues among insurers, and the continuing solvency of various insurance companies, as well as the numerous uncertainties surrounding asbestos litigation in the United States, could cause the actual costs and insurance recoveries for Union Carbide to be higher or lower than those projected or those recorded.

For additional information, see Legal Proceedings in the 2010 10-K, Asbestos-Related Matters of Union Carbide Corporation in Management’s Discussion and Analysis of Financial Condition and Results of Operations, and Note N to the Consolidated Financial Statements.

Environmental Matters

The Company determines the costs of environmental remediation of its facilities and formerly owned facilities based on evaluations of current law and existing technologies. Inherent uncertainties exist in such evaluations primarily due to unknown environmental conditions, changing governmental regulations and legal standards regarding liability, and emerging remediation technologies. The recorded liabilities are adjusted periodically as remediation efforts progress, or as additional technical or legal information becomes available. In the case of landfills and other active waste management facilities, Dow recognizes the costs over the useful life of the facility. At December 31, 2010, the Company had accrued obligations of $607 million for probable environmental remediation and restoration costs, including $59 million for the remediation of Superfund sites. This is management’s best estimate of the costs for remediation and restoration with respect to environmental matters for which the Company has accrued liabilities, although the ultimate cost with respect to these particular matters could range up to approximately twice that amount. The Company had accrued obligations of $619 million at December 31, 2009 for probable environmental remediation and restoration costs, including $80 million for the remediation of Superfund sites. For further discussion, see Environmental Matters in Management’s Discussion and Analysis of Financial Condition and Results of Operations and Notes A and N to the Consolidated Financial Statements.

Goodwill

The Company assesses goodwill recoverability through business financial performance reviews, enterprise valuation analysis, and impairment tests.

Annual goodwill impairment tests are completed during the Company’s fourth quarter of the year in accordance with the subsequent measurement provisions of the accounting guidance for goodwill. The tests are performed at the reporting unit level which is defined as one level below operating segment with the exception of Agricultural Sciences, which is both an operating segment and a reporting unit. Reporting units are the level at which discrete financial information is available and reviewed by business management on a regular basis. The Company has defined six operating segments and 31 reporting units. Goodwill is carried by 19 of the Company’s 31 reporting units.

In addition to the annual goodwill impairment tests, the Company reviews the financial performance of its reporting units over the course of the year to assess whether circumstances have changed that would more likely than not indicate that the fair value of a reporting unit has declined below its carrying value. In cases where an indication of impairment is determined to exist, the Company completes an interim goodwill impairment test specifically for that reporting unit.

The Company utilizes a discounted cash flow methodology to calculate the fair value of its reporting units. This valuation technique has been selected by management as the most meaningful valuation method due to the limited number of market comparables for the Company’s reporting units. However, where market comparables are available, the Company includes EBIT/EBITDA multiples as part of the reporting unit valuation analysis.

The discounted cash flow valuations are completed with the use of key assumptions, including projected revenue growth rate, discount rate, tax rate, currency exchange rates, terminal value, and long-term hydrocarbons and energy prices. These key assumptions are reevaluated with each annual impairment test and updated based on current facts and circumstances. Currency exchange rates, and long-term hydrocarbons and energy prices are established for the Company as a whole and applied consistently to all reporting units, while tax rates, revenue growth rates, terminal values (calculated using the key value driver implementation of the Gordon growth model), and discount rates are established by reporting unit to account for differences in business fundamentals and industry risk.

For the 2010 annual impairment test, currency exchange rates were projected by year for 66 currencies, and long-term hydrocarbons and energy prices were forecast by geographic area by year and included all key feedstocks as well as natural gas and crude oil (due to the correlation to naphtha). Tax rates varied by reporting unit with the average rate being 27 percent. Discount rates ranged from 8.1 percent to 10.5 percent based on an assessment of likely market participants and relative industry risk of each reporting unit. Terminal values were differentiated based on the cash flow projections of each reporting unit and the projected Net Operating Profit After Tax (“NOPAT”) growth rate, which ranged from negative 2.2 percent to positive 4.5 percent. Revenue growth rates, or Compounded Annual Growth Rates (“CAGR”) over a ten-year cash flow forecast period, varied by reporting unit based on underlying business fundamentals and future expectations with rates ranging from 1 percent to 15 percent.

Changes in key assumptions can affect the results of goodwill impairment tests. The changes made to key assumptions in 2010 did not result in a significant change in the impairment analysis conclusion. The key assumptions with the most significant impact on reporting unit fair value calculations include the discount rate and terminal value NOPAT growth rate. For the 2010 impairment test, management completed sensitivity analyses on both of these key assumptions. An increase of 100 basis points in the discount rate would have resulted in a fair value, based on discounted cash flows, which exceeded the carrying value for all of the Company’s reporting units that carry goodwill. For the terminal value NOPAT growth rate, a decrease of 100 basis points would have resulted in a fair value, based on discounted cash flows, which exceeded the carrying value for all of the Company’s reporting units that carry goodwill. Additional sensitivity analysis was completed on the combined impact of a 100 basis point increase in the discount rate and a 100 basis point decrease in the terminal value NOPAT growth rate. This analysis resulted in fair values, based on discounted cash flows, that exceeded carrying values for all reporting units that carry goodwill.

In completing the annual impairment test for 2010, management evaluated the reasonableness of differences noted between the fair value and carrying value of each reporting unit. All differences were determined to be reasonable.

Based on the fair value analysis completed by the Company in the fourth quarter of 2010, using the key assumptions defined for the Company as well as the key assumptions defined specifically for each reporting unit, management concluded that fair value exceeded carrying value for all reporting units that carry goodwill.

46

The same analysis was completed by the Company in the fourth quarter of 2009 and management concluded that the fair value exceeded carrying value for all reporting units that carry goodwill except the Dow Haltermann reporting unit. As a result, the Company recorded a goodwill impairment charge of $7 million in the fourth quarter of 2009, which represented the total amount of goodwill carried by the Dow Haltermann reporting unit. Due to the conclusion that the goodwill associated with the Dow Haltermann reporting unit was impaired, management also initiated a review of the underlying assets of the reporting unit to assess whether or not any additional asset impairment existed. Based on the undiscounted cash flow analysis completed in accordance with ASC Topic 360, “Property, Plant, and Equipment,” no further impairment existed.

The Company also monitors and evaluates its market capitalization relative to book value. When the market capitalization of the Company falls below book value, management undertakes a process to evaluate whether a change in circumstances has occurred that would indicate it is more likely than not that the fair value of any of its reporting units has declined below carrying value. This evaluation process includes the use of third-party market-based valuations and internal discounted cash flow analysis. As part of the annual goodwill impairment test, the Company also compares market capitalization with the total estimated fair value of its reporting units to ensure that significant differences are understood. At December 31, 2010 and December 31, 2009, Dow’s market capitalization exceeded book value.

Pension and Other Postretirement Benefits

The amounts recognized in the consolidated financial statements related to pension and other postretirement benefits are determined from actuarial valuations. Inherent in these valuations are assumptions including expected return on plan assets, discount rates at which the liabilities could have been settled at December 31, 2010, rate of increase in future compensation levels, mortality rates and health care cost trend rates. These assumptions are updated annually and are disclosed in Note Q to the Consolidated Financial Statements. In accordance with U.S. GAAP, actual results that differ from the assumptions are accumulated and amortized over future periods and, therefore, affect expense recognized and obligations recorded in future periods. The U.S. pension plans represent approximately 71 percent of the Company’s pension plan assets and 72 percent of the pension obligations.

The following information relates to the U.S. plans only; a similar approach is used for the Company’s non-U.S. plans.

The Company determines the expected long-term rate of return on assets by performing a detailed analysis of historical and expected returns based on the strategic asset allocation approved by the Board of Directors and the underlying return fundamentals of each asset class. The Company’s historical experience with the pension fund asset performance is also considered. The expected return of each asset class is derived from a forecasted future return confirmed by historical experience. The expected long-term rate of return is an assumption and not what is expected to be earned in any one particular year. The weighted-average long-term rate of return assumption used for determining net periodic pension expense for 2010 was 8.16 percent. This assumption was unchanged for determining 2011 net periodic pension expense. Future actual pension expense will depend on future investment performance, changes in future discount rates and various other factors related to the population of participants in the Company’s pension plans.

The discount rates utilized to measure the pension and other postretirement obligations of the U.S. qualified plans are based on the yield on high-quality fixed income instruments at the measurement date. Future expected actuarially determined cash flows of Dow’s major U.S. plans are matched against the Towers Watson RATE:Link yield curve (based on 60th to 90th percentile bond yields) to arrive at a single discount rate by plan. The weighted average discount rate was 5.51 percent at December 31, 2010 and 5.97 percent at December 31, 2009.

At December 31, 2010, the U.S. qualified plans were underfunded on a projected benefit obligation basis by $3.3 billion. The underfunded amount increased by approximately $100 million compared with December 31, 2009. The increase was primarily due to lower discount rates partially offset by favorable plan asset returns and contributions during the year. The Company contributed $435 million to the U.S. qualified plans in 2010.

The assumption for the long-term rate of increase in compensation levels for the principal U.S. qualified plans was 4.50 percent. Since 2002, the Company has used a generational mortality table to determine the duration of its pension and other postretirement obligations.

47

The following discussion relates to all of the Company’s pension plans.

The Company bases the determination of pension expense or income on a market-related valuation of plan assets that reduces year-to-year volatility. This market-related valuation recognizes investment gains or losses over a five-year period from the year in which they occur. Investment gains or losses for this purpose represent the difference between the expected return calculated using the market-related value of plan assets and the actual return based on the market value of plan assets. Since the market-related value of plan assets recognizes gains or losses over a five-year period, the future value of plan assets will be impacted when previously deferred gains or losses are recorded. Over the life of the plan, both gains and losses have been recognized and amortized. At December 31, 2010, net losses of $827 million remain to be recognized in the calculation of the market-related value of plan assets. These net losses will result in increases in future pension expense as they are recognized in the market-related value of assets and are a component of the total net loss of $6,696 million for 2010 shown under “Pretax amounts recognized in AOCI at December 31” in the table entitled “Change in Projected Benefit Obligations, Plan Assets and Funded Status of All Significant Plans” included in Note Q to the Consolidated Financial Statements. The other $5,869 million of net losses represents cumulative changes in plan experience and actuarial assumptions. The net decrease or increase in the market-related value of assets due to the recognition of prior gains and losses is presented in the following table:

Net Decrease (Increase) in Market-Related Asset Value Due to Recognition of Prior Gains and Losses In millions
2011	$	566
2012	628
2013	(271		)
2014	(96		)
Total	$	827

Based on the 2011 pension assumptions and the changes in the market-related value of assets due to the recognition of prior asset losses, the Company expects net periodic benefit costs to increase by approximately $60 million for all pension and other postretirement benefits in 2011 compared with 2010.

A 25 basis point increase or decrease in the long-term return on assets assumption would change the Company’s total pension expense for 2011 by approximately $41 million. A 25 basis point increase or decrease in the discount rate assumption would change the Company’s total pension expense for 2011 by approximately $50 million. A 25 basis point change in the long-term return and discount rate assumptions would have an immaterial impact on the other postretirement benefit expense for 2011.

Income Taxes

Deferred tax assets and liabilities are determined based on temporary differences between the financial reporting and tax bases of assets and liabilities, applying enacted tax rates expected to be in effect for the year in which the differences are expected to reverse. Based on the evaluation of available evidence, both positive and negative, the Company recognizes future tax benefits, such as net operating loss carryforwards and tax credit carryforwards, to the extent that realizing these benefits is considered to be more likely than not.

At December 31, 2010, the Company had a net deferred tax asset balance of $1,290 million, after valuation allowances of $682 million.

In evaluating the ability to realize the deferred tax assets, the Company relies on, in order of increasing subjectivity, taxable income in prior carryback years, the future reversals of existing taxable temporary differences, tax planning strategies and forecasted taxable income using historical and projected future operating results.

At December 31, 2010, the Company had deferred tax assets for tax loss and tax credit carryforwards of $1,957 million, $62 million of which is subject to expiration in the years 2011-2015. In order to realize these deferred tax assets for tax loss and tax credit carryforwards, the Company needs taxable income of approximately $6,790 million across multiple jurisdictions. The taxable income needed to realize the deferred tax assets for tax loss and tax credit carryforwards that are subject to expiration between 2011-2015 is approximately $469 million.

48

The Company recognizes the financial statement effects of an uncertain income tax position when it is more likely than not, based on technical merits, that the position will be sustained upon examination. At December 31, 2010, the Company had uncertain tax positions for both domestic and foreign issues of $319 million.

The Company accrues for non-income tax contingencies when it is probable that a liability to a taxing authority has been incurred and the amount of the contingency can be reasonably estimated. At December 31, 2010, the Company had a non-income tax contingency reserve for both domestic and foreign issues of $156 million.

Environmental Policies

Dow is committed to world-class environmental, health and safety (“EH&S”) performance, as demonstrated by industry-leading performance, a long-standing commitment to Responsible Care^®, and a strong commitment to achieve the Company’s 2015 Sustainability Goals – goals that set the standard for sustainability in the chemical industry by focusing on improvements in Dow’s local corporate citizenship and product stewardship, and by actively pursuing methods to reduce the Company’s environmental impact.

To meet the Company’s public commitments, as well as the stringent laws and government regulations related to environmental protection and remediation to which its global operations are subject, Dow has well-defined policies, requirements and management systems. Dow’s EH&S Management System (“EMS”) defines the “who, what, when and how” needed for the businesses to achieve the Company’s policies, requirements, performance objectives, leadership expectations and public commitments. To ensure effective utilization, the EMS is integrated into a company-wide management system for EH&S, Operations, Quality and Human Resources.

It is Dow’s policy to adhere to a waste management hierarchy that minimizes the impact of wastes and emissions on the environment. First, Dow works to eliminate or minimize the generation of waste and emissions at the source through research, process design, plant operations and maintenance. Second, Dow finds ways to reuse and recycle materials. Finally, unusable or non-recyclable hazardous waste is treated before disposal to eliminate or reduce the hazardous nature and volume of the waste. Treatment may include destruction by chemical, physical, biological or thermal means. Disposal of waste materials in landfills is considered only after all other options have been thoroughly evaluated. Dow has specific requirements for waste that is transferred to non-Dow facilities, including the periodic auditing of these facilities.

Dow believes third-party verification and transparent public reporting are cornerstones of world-class EH&S performance and building public trust. As such, numerous Dow sites in Europe, Latin America, Asia Pacific and North America have received third-party verification of Dow’s compliance with Responsible Care^® and with outside specifications such as ISO-14001. Dow continues to be a global champion of Responsible Care^® and has worked to broaden the application and impact of Responsible Care^® around the world through engagement with suppliers, customers and joint venture partners.

Dow’s EH&S policies helped the Company achieve excellent EH&S performance in 2010. In recognition, the Company was presented the esteemed National Safety Council’s Robert W. Campbell Award for 2010. Dow’s injury/illness rates and process safety performance were excellent in 2010, and the Company is favorably positioned to achieve its 2015 sustainability goals in these key areas. Further improvement in these areas, as well as environmental compliance, remains a top management priority, with initiatives underway to further improve performance and compliance in 2011.

Detailed information on Dow’s performance regarding environmental matters and goals can be found online on Dow’s Sustainability webpage at www.dow.com.

Chemical Security

Public and political attention continues to be placed on the protection of critical infrastructure, including the chemical industry, from security threats. Terrorist attacks and natural disasters have increased concern about the security and safety of chemical production and distribution. Many, including Dow and the American Chemistry Council, have called for uniform risk-based and performance-based national standards for securing the U.S. chemical industry. The Maritime Transportation Security Act (“MTSA”) of 2002 and its regulations further set forth risk-based and performance-based standards that must be met at U.S. Coast Guard-regulated facilities. U.S. Chemical Plant Security legislation was passed in 2006 and the Department of Homeland Security (“DHS”) is now implementing the regulations known as the Chemical Facility Anti-Terrorism Standards. The Company is complying with the requirements of the Rail Transportation Security Rule issued by the U.S. Transportation Security Administration (“TSA”). Dow continues to support uniform risk-based national standards for securing the chemical industry.

49

The focus on security is not new to Dow. A comprehensive, multi-level security plan for the Company has been maintained since 1988. This plan, which has been activated in response to significant world and national events since then, is reviewed on an annual basis. Dow continues to improve its security plans, placing emphasis on the safety of Dow communities and people by being prepared to meet risks at any level and to address both internal and external identifiable risks. The security plan includes regular vulnerability assessments, security audits, mitigation efforts and physical security upgrades designed to reduce vulnerability. Dow’s security plans also are developed to avert interruptions of normal business work operations that could materially and adversely affect the Company’s results of operations, liquidity and financial condition.

Dow played a key role in the development and implementation of the American Chemistry Council’s Responsible Care^® Security Code, which requires that all aspects of security – including facility, transportation and cyberspace – be assessed and gaps addressed. Through the Company’s global implementation of the Security Code, Dow has permanently heightened the level of security – not just in the United States, but worldwide. Dow employs several hundred employees and contractors in its Emergency Services and Security department worldwide.

Through the implementation of the Security Code, including voluntary security enhancements and upgrades made since 2002, Dow is well-positioned to comply with the new U.S. chemical facility regulations and other regulatory security frameworks. In addition, Dow was the first chemical company to receive coverage under the Support Anti-terrorism by Fostering Effective Technologies Act (“SAFETY Act”) from the DHS in 2007 for the Company’s MTSA regulated sites, and the first to receive coverage under SAFETY Act in 2008 for the Company’s Rail Transportation Security Services. This unprecedented certification helps validate Dow’s efforts and provides additional liability coverage in the event of a terrorist attack.

Dow continues to work collaboratively across the supply chain on Responsible Care^®, Supply Chain Design, Emergency Preparedness, Shipment Visibility and transportation of hazardous materials. Dow is cooperating with public and private entities to lead the implementation of advanced tank car design, and track and trace technologies. Further, Dow’s Distribution Risk Review process that has been in place for decades was expanded to address potential threats in all modes of transportation across the Company’s supply chain. To reduce vulnerabilities, Dow maintains security measures that meet or exceed regulatory and industry security standards in all areas in which the Company operates.

Dow continually works to strengthen partnerships with local responders, law enforcement and security agencies, and to enhance confidence in the integrity of the Company’s security and risk management program, as well as strengthen its preparedness and response capabilities. Dow also works closely with its supply chain partners and strives to educate lawmakers, regulators and communities about the Company’s resolve and actions to date that mitigate security and crisis threats.

Climate Change

Dow is committed to reducing its greenhouse gas (“GHG”) intensity (pounds of GHG per pound of product), developing climate-friendly products and processes and, over the longer term, implementing technology solutions to achieve even greater climate change improvements. Since 1990, Dow has reduced its absolute GHG emissions by more than 20 percent, a more rapid reduction than required by Kyoto Protocol targets. Since 1994, Dow has achieved a 22 percent improvement in energy intensity (the amount of energy required to produce one pound of product). In doing so, it has avoided consuming more than 1,700 trillion Btus, a savings that when converted to electricity would more than supply the residential electrical energy needs of California for one year. Through its energy savings, Dow has prevented approximately 90 million metric tons of carbon dioxide from entering the atmosphere. This trend could change, depending on business growth, capacity utilization and the pace of new technology development.

Dow, through its science and technology capabilities, is committed to bringing solutions to the challenge of climate change by producing products that help others reduce GHG emissions, such as lightweight plastics for automobiles and insulation for energy efficient homes and appliances. For example, Dow’s building insulation materials and air-sealing products can save up to 20 percent on heating and cooling costs and significantly reduce GHG emissions. The Company’s STYROFOAM™ insulation is installed in over 20 million buildings worldwide, saving over $10 billion in energy costs annually. Dow’s DOWTHERM™ A heat transfer fluids are used in 14 large concentrating solar power plants, with a total capacity of over 700 megawatts. These plants will provide power for the equivalent of approximately 415,000 homes and save 1.6 million metric tons of carbon dioxide emissions per year.

Gains made toward Dow’s Energy Efficiency goal will directly impact progress in reducing GHG intensity. Dow is studying the life cycle impact of its products on climate change and additional global projects that could offset the Company’s overall GHG emissions through carbon dioxide reduction. Although the Company has some units subject to the European

50

Union’s Emissions Trading Scheme (“EU ETS”), the Company has not experienced any considerable impact in regard to regulated GHG emissions from the EU ETS. Dow will continue to evaluate and monitor future developments that may affect operations in the region.

Dow’s Energy & Climate Change Policy and Issue Management Team is tasked with developing and implementing a comprehensive strategy that addresses the challenges of climate change and energy security and is advocating an international framework that establishes clear pathways to help slow, stop and reverse the rate of GHG emissions globally.

Environmental Remediation

Dow accrues the costs of remediation of its facilities and formerly owned facilities based on current law and existing technologies. The nature of such remediation includes, for example, the management of soil and groundwater contamination and the closure of contaminated landfills and other waste management facilities. In the case of landfills and other active waste management facilities, Dow recognizes the costs over the useful life of the facility. The accounting policies adopted to properly reflect the monetary impacts of environmental matters are discussed in Note A to the Consolidated Financial Statements. To assess the impact on the financial statements, environmental experts review currently available facts to evaluate the probability and scope of potential liabilities. Inherent uncertainties exist in such evaluations primarily due to unknown environmental conditions, changing governmental regulations and legal standards regarding liability, and emerging remediation technologies. These liabilities are adjusted periodically as remediation efforts progress or as additional technical or legal information becomes available. Dow had an accrued liability of $548 million at December 31, 2010, related to the remediation of current or former Dow-owned sites. At December 31, 2009, the liability related to remediation was $539 million.

In addition to current and former Dow-owned sites, under the Federal Comprehensive Environmental Response, Compensation and Liability Act and equivalent state laws (hereafter referred to collectively as “Superfund Law”), Dow is liable for remediation of other hazardous waste sites where Dow allegedly disposed of, or arranged for the treatment or disposal of, hazardous substances. Because Superfund Law imposes joint and several liability upon each party at a site, Dow has evaluated its potential liability in light of the number of other companies that also have been named potentially responsible parties (“PRPs”) at each site, the estimated apportionment of costs among all PRPs, and the financial ability and commitment of each to pay its expected share. The Company’s remaining liability for the remediation of Superfund sites was $59 million at December 31, 2010 ($80 million at December 31, 2009). The Company has not recorded any third-party recovery related to these sites as a receivable.

Information regarding environmental sites is provided below:

Environmental Sites	Dow-owned Sites (1)				Superfund Sites (2)
	2010		2009		2010		2009
Number of sites at January 1	291		252		124		85

Sites closed during year	(4	)	(5	)	(7	)	(6	)
Number of sites at December 31	289		291		120		124

(1) Dow-owned sites are sites currently or formerly owned by Dow, where remediation obligations are imposed in the United States by the Resource Conservation Recovery Act or analogous state law. 152 of these sites were formerly owned by Dowell Schlumberger, Inc., a group of companies in which the Company previously owned a 50-percent interest. Dow sold its interest in Dowell Schlumberger in 1992.

(2) Superfund sites are sites, including sites not owned by Dow, where remediation obligations are imposed by Superfund Law.

Additional information is provided below for the Company’s manufacturing sites in Freeport, Texas; Midland, Michigan; and Philadelphia, Pennsylvania, the sites for which the Company has the largest environmental remediation accruals; as well as a Superfund site in Wood-Ridge, New Jersey.

From the start of operations at the Freeport site in the 1940s until the mid-1970s, manufacturing wastes were typically placed in on-site pits and landfills. The resulting soil and groundwater contamination is being assessed and remediated under the provisions of the Resource Conservation Recovery Act (“RCRA”), in concert with the state of Texas. At December 31, 2010, the Company had an accrual of $28 million ($29 million at December 31, 2009) related to environmental remediation at the Freeport manufacturing site. In 2010, $3 million ($3 million in 2009) was spent on environmental remediation at the Freeport site.

51

Similar to the Freeport site, in the early days of operations at the Midland site, manufacturing wastes were usually disposed of on-site, resulting in soil and groundwater contamination, which has been contained and managed on-site under a series of RCRA permits and regulatory agreements. The most recent Hazardous Waste Operating License for the Midland site, issued in 2003, also included provisions for the Company to conduct an investigation to determine the nature and extent of off-site contamination from historic Midland site operations. The scope of the investigation includes Midland area soils; the Tittabawassee and Saginaw River sediment and floodplain soils; and Saginaw Bay, and requires the Company to conduct interim response actions. In January 2010, the Company entered into a Federal Comprehensive Environmental Response, Compensation, and Liability Act Administrative Order on Consent to perform a Remedial Investigation, Feasibility Study and Remedial Design for the Tittabawassee and Saginaw River sediment and floodplain soils, and Saginaw Bay. See Note N to the Consolidated Financial Statements for additional information. At December 31, 2010, the Company had an accrual of $71 million ($64 million at December 31, 2009) for environmental remediation and investigation associated with the Midland site. In 2010, the Company spent $16 million ($19 million in 2009) on environmental remediation at the Midland site.

On April 1, 2009, the Company acquired Rohm and Haas’ Philadelphia Plant, which has been an industrial site since the early 1700s, and since the 1920s used by Rohm and Haas for the manufacture of a wide range of chemical products. Chemical disposal practices in the early years resulted in soil and groundwater contamination at the site and in the sediments of the adjacent Frankford Inlet. The site has undergone a number of investigations and interim cleanup measures under the RCRA Corrective Action Program, and in 2009, was transferred to the regulatory management of the Pennsylvania One Cleanup Program. At December 31, 2010, the Company had an accrual of $56 million ($58 million at December 31, 2009) for environmental remediation at the Philadelphia Plant. In 2010, the Company spent $1 million ($1 million in 2009, following the April 1, 2009 acquisition) on environmental remediation at the Philadelphia Plant.

Rohm and Haas is a lead PRP at the Wood-Ridge, New Jersey Ventron/Velsicol Superfund Site, and the adjacent Berry’s Creek Study Area. Rohm and Haas is a successor in interest to a company that owned and operated a mercury processing facility, where wastewater and waste handling resulted in contamination of soils and adjacent creek sediments. The Ventron/Velsicol site is currently undergoing remediation. The Berry’s Creek Study Area is under the preliminary remedial investigation phase and the PRP group is conducting an investigation of sediment contamination in Berry’s Creek. Sediment removal was undertaken by the PRP group in 2009 in connection with an unrelated project to replace a flood control tidegate in the creek. At December 31, 2010, the Company had an accrual of $9 million ($25 million at December 31, 2009) for environmental remediation at the two Wood-Ridge sites. In 2010, the Company spent $22 million ($24 million in 2009, following the April 1, 2009 acquisition) on environmental remediation at the two Wood-Ridge sites.

In total, the Company’s accrued liability for probable environmental remediation and restoration costs was $607 million at December 31, 2010, compared with $619 million at the end of 2009. This is management’s best estimate of the costs for remediation and restoration with respect to environmental matters for which the Company has accrued liabilities, although the ultimate cost with respect to these particular matters could range up to approximately twice that amount. Consequently, it is reasonably possible that environmental remediation and restoration costs in excess of amounts accrued could have a material adverse impact on the Company’s results of operations, financial condition and cash flows. It is the opinion of the Company’s management, however, that the possibility is remote that costs in excess of the range disclosed will have a material adverse impact on the Company’s results of operations, financial condition and cash flows.

The amounts charged to income on a pretax basis related to environmental remediation totaled $158 million in 2010, $269 million in 2009 and $140 million in 2008. The amounts charged to income on a pretax basis related to operating the Company’s current pollution abatement facilities totaled $706 million in 2010, $675 million in 2009 and $723 million in 2008. Capital expenditures for environmental protection were $173 million in 2010, $219 million in 2009 and $193 million in 2008.

Asbestos-Related Matters of Union Carbide Corporation

Introduction

Union Carbide Corporation (“Union Carbide”), a wholly owned subsidiary of the Company, is and has been involved in a large number of asbestos-related suits filed primarily in state courts during the past three decades. These suits principally allege personal injury resulting from exposure to asbestos-containing products and frequently seek both actual and punitive damages. The alleged claims primarily relate to products that Union Carbide sold in the past, alleged exposure to asbestos-containing products located on Union Carbide’s premises, and Union Carbide’s responsibility for asbestos suits filed against a former Union Carbide subsidiary, Amchem Products, Inc. (“Amchem”). In many cases, plaintiffs are unable to demonstrate that they have suffered any compensable loss as a result of such exposure, or that injuries incurred in fact resulted from exposure to Union Carbide’s products.

52

Influenced by the bankruptcy filings of numerous defendants in asbestos-related litigation and the prospects of various forms of state and national legislative reform, the rate at which plaintiffs filed asbestos-related suits against various companies, including Union Carbide and Amchem, increased in 2001, 2002 and the first half of 2003. Since then, the rate of filing has significantly abated. Union Carbide expects more asbestos-related suits to be filed against Union Carbide and Amchem in the future, and will aggressively defend or reasonably resolve, as appropriate, both pending and future claims.

The table below provides information regarding asbestos-related claims filed against Union Carbide and Amchem:

	2010		2009		2008
Claims unresolved at January 1	75,030		75,706		90,322
Claims filed	7,731		8,455		10,922
Claims settled, dismissed or otherwise resolved	(20,179	)	(9,131	)	(25,538	)
Claims unresolved at December 31	62,582		75,030		75,706
Claimants with claims against both UCC and Amchem	18,890		24,146		24,213
Individual claimants at December 31	43,692		50,884		51,493

Plaintiffs’ lawyers often sue numerous defendants in individual lawsuits or on behalf of numerous claimants. As a result, the damages alleged are not expressly identified as to Union Carbide, Amchem or any other particular defendant, even when specific damages are alleged with respect to a specific disease or injury. In fact, there are no personal injury cases in which only Union Carbide and/or Amchem are the sole named defendants. For these reasons and based upon Union Carbide’s litigation and settlement experience, Union Carbide does not consider the damages alleged against Union Carbide and Amchem to be a meaningful factor in its determination of any potential asbestos-related liability.

Estimating the Liability

Based on a study completed by Analysis, Research & Planning Corporation (“ARPC”) in January 2003, Union Carbide increased its December 31, 2002 asbestos-related liability for pending and future claims for the 15-year period ending in 2017 to $2.2 billion, excluding future defense and processing costs. Since then, Union Carbide has compared current asbestos claim and resolution activity to the results of the most recent ARPC study at each balance sheet date to determine whether the accrual continues to be appropriate. In addition, Union Carbide has requested ARPC to review Union Carbide’s historical asbestos claim and resolution activity each November since 2004 to determine the appropriateness of updating the most recent ARPC study.

In November 2008, Union Carbide requested ARPC to review Union Carbide’s historical asbestos claim and resolution activity and determine the appropriateness of updating its then most recent study completed in December 2006. In response to that request, ARPC reviewed and analyzed data through October 31, 2008. The resulting study, completed by ARPC in December 2008, stated that the undiscounted cost of resolving pending and future asbestos-related claims against Union Carbide and Amchem, excluding future defense and processing costs, through 2023 was estimated to be between $952 million and $1.2 billion. As in its earlier studies, ARPC provided estimates for a longer period of time in its December 2008 study, but also reaffirmed its prior advice that forecasts for shorter periods of time are more accurate than those for longer periods of time.

In December 2008, based on ARPC’s December 2008 study and Union Carbide’s own review of the asbestos claim and resolution activity, Union Carbide decreased its asbestos-related liability for pending and future claims to $952 million, which covered the 15-year period ending 2023, excluding future defense and processing costs. The reduction was $54 million and is shown as “Asbestos-related credits” in the consolidated statements of income. At December 31, 2008, the asbestos-related liability for pending and future claims was $934 million.

In November 2009, Union Carbide requested ARPC to review Union Carbide’s 2009 asbestos claim and resolution activity and determine the appropriateness of updating its December 2008 study. In response to that request, ARPC reviewed and analyzed data through October 31, 2009. In December 2009, ARPC stated that an update of its study would not provide a more likely estimate of future events than the estimate reflected in its study of the previous year and, therefore, the estimate in that study remained applicable. Based on Union Carbide’s own review of the asbestos claim and resolution activity and ARPC’s response, Union Carbide determined that no change to the accrual was required. At December 31, 2009, Union Carbide’s asbestos-related liability for pending and future claims was $839 million.

In November 2010, Union Carbide requested ARPC to review Union Carbide’s historical asbestos claim and resolution activity and determine the appropriateness of updating its December 2008 study. In response to that request, ARPC reviewed and analyzed data through October 31, 2010. The resulting study, completed by ARPC in December 2010, stated that the undiscounted cost of resolving pending and future asbestos-related claims against Union Carbide and Amchem, excluding

53

future defense and processing costs, through 2025 was estimated to be between $744 million and $835 million. As in its earlier studies, ARPC provided estimates for a longer period of time in its December 2010 study, but also reaffirmed its prior advice that forecasts for shorter periods of time are more accurate than those for longer periods of time.

In December 2010, based on ARPC’s December 2010 study and Union Carbide’s own review of the asbestos claim and resolution activity, Union Carbide decreased its asbestos-related liability for pending and future claims to $744 million, which covered the 15-year period ending 2025, excluding future defense and processing costs. The reduction was $54 million and was shown as “Asbestos-related credits” in the consolidated statements of income. At December, 31, 2010, the asbestos-related liability for pending and future claims was $728 million.

At December 31, 2010, approximately 21 percent of the recorded liability related to pending claims and approximately 79 percent related to future claims. At December 31, 2009, approximately 23 percent of the recorded liability related to pending claims and approximately 77 percent related to future claims.

Defense and Resolution Costs

The following table provides information regarding defense and resolution costs related to asbestos-related claims filed against Union Carbide and Amchem:

Defense and Resolution Costs							Aggregate Costs
In millions	2010		2009		2008		to Date as of Dec.  31, 2010
Defense costs	$	87	$	62	$	60	$	774
Resolution costs	$	43	$	94	$	116	$	1,523

The average resolution payment per asbestos claimant and the rate of new claim filings has fluctuated both up and down since the beginning of 2001. Union Carbide’s management expects such fluctuations to continue in the future based upon a number of factors, including the number and type of claims settled in a particular period, the jurisdictions in which such claims arose, and the extent to which any proposed legislative reform related to asbestos litigation is being considered.

Union Carbide expenses defense costs as incurred. The pretax impact for defense and resolution costs, net of insurance, was $73 million in 2010, $58 million in 2009 and $53 million in 2008, and was reflected in “Cost of sales” in the consolidated statements of income.

Insurance Receivables

At December 31, 2002, Union Carbide increased the receivable for insurance recoveries related to its asbestos liability to $1.35 billion, substantially exhausting its asbestos product liability coverage. The insurance receivable related to the asbestos liability was determined by Union Carbide after a thorough review of applicable insurance policies and the 1985 Wellington Agreement, to which Union Carbide and many of its liability insurers are signatory parties, as well as other insurance settlements, with due consideration given to applicable deductibles, retentions and policy limits, and taking into account the solvency and historical payment experience of various insurance carriers. The Wellington Agreement and other agreements with insurers are designed to facilitate an orderly resolution and collection of Union Carbide’s insurance policies and to resolve issues that the insurance carriers may raise.

In September 2003, Union Carbide filed a comprehensive insurance coverage case, now proceeding in the Supreme Court of the State of New York, County of New York, seeking to confirm its rights to insurance for various asbestos claims and to facilitate an orderly and timely collection of insurance proceeds (the “Insurance Litigation”). The Insurance Litigation was filed against insurers that are not signatories to the Wellington Agreement and/or do not otherwise have agreements in place with Union Carbide regarding their asbestos-related insurance coverage, in order to facilitate an orderly resolution and collection of such insurance policies and to resolve issues that the insurance carriers may raise. Since the filing of the case, Union Carbide has reached settlements with several of the carriers involved in the Insurance Litigation, including settlements reached with two significant carriers in the fourth quarter of 2009. The Insurance Litigation is ongoing.

Union Carbide’s receivable for insurance recoveries related to its asbestos liability was $50 million at December 31, 2010 and $84 million at December 31, 2009. At December 31, 2010 and December 31, 2009, all of the receivable for insurance recoveries was related to insurers that are not signatories to the Wellington Agreement and/or do not otherwise have agreements in place regarding their asbestos-related insurance coverage.

54

In addition to the receivable for insurance recoveries related to its asbestos liability, Union Carbide had receivables for defense and resolution costs submitted to insurance carriers that have settlement agreements in place regarding their asbestos-related insurance coverage. The following table summarizes Union Carbide’s receivables related to its asbestos-related liability:

Receivables for Asbestos-Related Costs at December 31  In millions	2010		2009
Receivables for defense costs – carriers with settlement agreements	$	12	$	91
Receivables for resolution costs – carriers with settlement agreements	236		357
Receivables for insurance recoveries – carriers without settlement agreements	50		84
Total	$	298	$	532

After a review of its insurance policies, with due consideration given to applicable deductibles, retentions and policy limits, after taking into account the solvency and historical payment experience of various insurance carriers; existing insurance settlements; and the advice of outside counsel with respect to the applicable insurance coverage law relating to the terms and conditions of its insurance policies, Union Carbide continues to believe that its recorded receivable for insurance recoveries from all insurance carriers is probable of collection.

Summary

The amounts recorded by Union Carbide for the asbestos-related liability and related insurance receivable described above were based upon current, known facts. However, future events, such as the number of new claims to be filed and/or received each year, the average cost of disposing of each such claim, coverage issues among insurers, and the continuing solvency of various insurance companies, as well as the numerous uncertainties surrounding asbestos litigation in the United States, could cause the actual costs and insurance recoveries for Union Carbide to be higher or lower than those projected or those recorded.

Because of the uncertainties described above, Union Carbide’s management cannot estimate the full range of the cost of resolving pending and future asbestos-related claims facing Union Carbide and Amchem. Union Carbide’s management believes that it is reasonably possible that the cost of disposing of Union Carbide’s asbestos-related claims, including future defense costs, could have a material adverse impact on Union Carbide’s results of operations and cash flows for a particular period and on the consolidated financial position of Union Carbide.

It is the opinion of Dow’s management that it is reasonably possible that the cost of Union Carbide disposing of its asbestos-related claims, including future defense costs, could have a material adverse impact on the Company’s results of operations and cash flows for a particular period and on the consolidated financial position of the Company.

Matters Involving the Formation of K-Dow Petrochemicals

Introduction

On December 13, 2007, the Company and Petrochemical Industries Company (K.S.C.) (“PIC”) of Kuwait, a wholly owned subsidiary of Kuwait Petroleum Corporation (“KPC”), announced plans to form a 50:50 global petrochemicals joint venture. The proposed joint venture, K-Dow Petrochemicals (“K-Dow”), was expected to have revenues of more than $11 billion and employ more than 5,000 people worldwide.

On November 28, 2008, the Company entered into a Joint Venture Formation Agreement (the “JVFA”) with PIC that provided for the establishment of K-Dow. To form the joint venture, the Company would transfer by way of contribution and sale to K-Dow, assets used in the research, development, manufacture, distribution, marketing and sale of polyethylene, polypropylene, polycarbonate, polycarbonate compounds and blends, ethyleneamines, ethanolamines, and related licensing and catalyst technologies; and K-Dow would assume certain related liabilities. PIC would receive a 50-percent equity interest in K-Dow in exchange for the payment by PIC of the initial purchase price, estimated to be $7.5 billion. The purchase price was subject to certain post-closing adjustments.

Failure to Close

On December 31, 2008, the Company received a written notice from PIC with respect to the JVFA advising the Company of PIC’s position that certain conditions to closing were not satisfied and, therefore, PIC was not obligated to close the transaction. On January 2, 2009, PIC refused to close the K-Dow transaction in accordance with the JVFA. The Company disagrees with the characterizations and conclusions expressed by PIC in the written notice and the Company has informed PIC that it breached the JVFA. On January 6, 2009, the Company announced that it would seek to fully enforce its rights under the terms of the JVFA and various related agreements.

Arbitration

The Company’s claims against PIC are subject to an arbitration agreement between the parties, which provides for arbitration under the Rules of Arbitration of the International Chamber of Commerce. On February 18, 2009, the Company initiated arbitration proceedings against PIC alleging that PIC breached the JVFA by failing to close the transaction on January 2, 2009. The Company is seeking damages in excess of $2.5 billion in the arbitration proceeding.

NOTE A – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation and Basis of Presentation

The accompanying consolidated financial statements of The Dow Chemical Company and its subsidiaries (“Dow” or the “Company”) were prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and include the assets, liabilities, revenues and expenses of all majority-owned subsidiaries over which the Company exercises control and, when applicable, entities for which the Company has a controlling financial interest or is the primary beneficiary. Intercompany transactions and balances are eliminated in consolidation. Investments in nonconsolidated affiliates (20-50 percent owned companies, joint ventures and partnerships) are accounted for using the equity method.

Certain changes to prior year balance sheet amounts have been made in accordance with the accounting guidance for business combinations to reflect adjustments made during the measurement period to provisional amounts recorded for assets acquired and liabilities assumed from Rohm and Haas Company (“Rohm and Haas”) on April 1, 2009. Certain changes have been made to geographic area information for prior years to reflect changes made in the first quarter of 2010. Certain changes have been made to operating segment information to reflect changes made in the third quarter of 2011 related to changes in the Company’s organization. A change to current year balance sheet amounts has been made to properly classify the current portion of "Deferred charges and other assets" of $349 million to "Other current assets."

63

Use of Estimates in Financial Statement Preparation

The preparation of financial statements in accordance with U.S. GAAP requires the use of estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. The Company’s consolidated financial statements include amounts that are based on management’s best estimates and judgments. Actual results could differ from those estimates.

Foreign Currency Translation

The local currency has been primarily used as the functional currency throughout the world. Translation gains and losses of those operations that use local currency as the functional currency are included in the consolidated balance sheets in “Accumulated other comprehensive income (loss)” (“AOCI”). Where the U.S. dollar is used as the functional currency, foreign currency gains and losses are reflected in income.

Environmental Matters

Accruals for environmental matters are recorded when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated based on current law and existing technologies. These accruals are adjusted periodically as assessment and remediation efforts progress or as additional technical or legal information becomes available. Accruals for environmental liabilities are included in the consolidated balance sheets in “Accrued and other current liabilities” and “Other noncurrent obligations” at undiscounted amounts. Accruals for related insurance or other third-party recoveries for environmental liabilities are recorded when it is probable that a recovery will be realized and are included in the consolidated balance sheets as “Accounts and notes receivable - Other.”

Environmental costs are capitalized if the costs extend the life of the property, increase its capacity, and/or mitigate or prevent contamination from future operations. Environmental costs are also capitalized in recognition of legal asset retirement obligations resulting from the acquisition, construction and/or normal operation of a long-lived asset. Costs related to environmental contamination treatment and cleanup are charged to expense. Estimated future incremental operations, maintenance and management costs directly related to remediation are accrued when such costs are probable and reasonably estimable.

Cash and Cash Equivalents

Cash and cash equivalents include time deposits and readily marketable securities with original maturities of three months or less.

Financial Instruments

The Company calculates the fair value of financial instruments using quoted market prices whenever available. When quoted market prices are not available for various types of financial instruments (such as forwards, options and swaps), the Company uses standard pricing models with market-based inputs that take into account the present value of estimated future cash flows.

The Company utilizes derivatives to manage exposures to currency exchange rates, commodity prices and interest rate risk. The fair values of all derivatives are recognized as assets or liabilities at the balance sheet date. Changes in the fair value of these instruments are reported in income or AOCI, depending on the use of the derivative and whether it qualifies for hedge accounting treatment.

Gains and losses on derivatives that are designated and qualify as cash flow hedging instruments are recorded in AOCI, to the extent the hedges are effective, until the underlying transactions are recognized in income. To the extent effective, gains and losses on derivative and nonderivative instruments used as hedges of the Company’s net investment in foreign operations are recorded in AOCI as part of the cumulative translation adjustment. The ineffective portions of cash flow hedges and hedges of net investment in foreign operations, if any, are recognized in income immediately.

Gains and losses on derivatives designated and qualifying as fair value hedging instruments, as well as the offsetting losses and gains on the hedged items, are reported in income in the same accounting period. Derivatives not designated as hedging instruments are marked-to-market at the end of each accounting period with the results included in income.

Inventories

Inventories are stated at the lower of cost or market. The method of determining cost for each subsidiary varies among last-in, first-out (“LIFO”); first-in, first-out (“FIFO”); and average cost, and is used consistently from year to year.

64

Property

Land, buildings and equipment, including property under capital lease agreements, are carried at cost less accumulated depreciation. Depreciation is based on the estimated service lives of depreciable assets and is calculated using the straight-line method, unless the asset was capitalized before 1997 when the declining balance method was used. Fully depreciated assets are retained in property and accumulated depreciation accounts until they are removed from service. In the case of disposals, assets and related accumulated depreciation are removed from the accounts, and the net amounts, less proceeds from disposal, are included in income.

Impairment and Disposal of Long-Lived Assets

The Company evaluates long-lived assets and certain identifiable intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. When undiscounted future cash flows are not expected to be sufficient to recover an asset’s carrying amount, the asset is written down to its fair value based on bids received from third parties or a discounted cash flow analysis based on market participant assumptions.

Long-lived assets to be disposed of by sale are classified as held for sale and are reported at the lower of carrying amount or fair value less cost to sell, and depreciation is ceased. Long-lived assets to be disposed of other than by sale are classified as held and used until they are disposed of and are reported at the lower of carrying amount or fair value, and depreciation is recognized over the remaining useful life of the assets.

Goodwill and Other Intangible Assets

The Company records goodwill when the purchase price of a business acquisition exceeds the estimated fair value of net identified tangible and intangible assets acquired. Goodwill is tested for impairment at the reporting unit level annually, or more frequently when events or changes in circumstances indicate that the fair value of a reporting unit has more likely than not declined below its carrying value. The Company primarily utilizes a discounted cash flow methodology to calculate the fair value of its reporting units.

Finite-lived intangible assets such as purchased customer lists, licenses, intellectual property, patents, trademarks and software, are amortized over their estimated useful lives, generally on a straight-line basis for periods ranging primarily from three to twenty years. Finite-lived intangible assets are reviewed for impairment or obsolescence annually, or more frequently when events or changes in circumstances indicate that the carrying amount of an intangible asset may not be recoverable. If impaired, intangible assets are written down to fair value based on discounted cash flows.

Asset Retirement Obligations

The Company records asset retirement obligations as incurred and reasonably estimable, including obligations for which the timing and/or method of settlement are conditional on a future event that may or may not be within the control of the Company. The fair values of obligations are recorded as liabilities on a discounted basis and are accreted over time for the change in present value. Costs associated with the liabilities are capitalized and amortized over the estimated remaining useful life of the asset, generally for periods of 10 years or less.

Investments

Investments in debt and marketable equity securities (including warrants), primarily held by the Company’s insurance operations, are classified as trading, available-for-sale or held-to-maturity. Investments classified as trading are reported at fair value with unrealized gains and losses included in income. Those classified as available-for-sale are reported at fair value with unrealized gains and losses recorded in AOCI. Those classified as held-to-maturity are recorded at amortized cost. The cost of investments sold is determined by specific identification. The Company routinely reviews available-for-sale and held-to-maturity securities for other-than-temporary declines in fair value below the cost basis, and when events or changes in circumstances indicate the carrying value of an asset may not be recoverable, the security is written down to fair value, establishing a new cost basis.

Revenue

Sales are recognized when the revenue is realized or realizable, and the earnings process is complete. Approximately 99 percent of the Company’s sales in 2010 related to sales of product. The remaining 1 percent in 2010 related to the Company’s service offerings, insurance operations, and licensing of patents and technology. Revenue for product sales is recognized as risk and title to the product transfer to the customer, which usually occurs at the time shipment is made. As such, title to the product passes when the product is delivered to the freight carrier. Dow’s standard terms of delivery are included in its contracts of sale, order confirmation documents and invoices. Freight costs and any directly related costs of transporting finished product to customers are recorded as “Cost of sales.”

65

Revenue related to the Company’s insurance operations includes third-party insurance premiums, which are earned over the terms of the related insurance policies and reinsurance contracts. Revenue related to the initial licensing of patents and technology is recognized when earned; revenue related to running royalties is recognized according to licensee production levels.

Legal Costs

The Company expenses legal costs, including those legal costs expected to be incurred in connection with a loss contingency, as incurred.

Severance Costs

The Company routinely reviews its operations around the world in an effort to ensure competitiveness across its businesses and geographic areas. When the reviews result in a workforce reduction related to the shutdown of facilities or other optimization activities, severance benefits are provided to employees primarily under Dow’s ongoing benefit arrangements. These severance costs are accrued under the guidance of the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification™ (“ASC”) Topic 712, “Compensation – Nonretirement Postemployment Benefits,” once management commits to a plan of termination including the number of employees to be terminated, their job classifications or functions, their locations and the expected completion date.

Income Taxes

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 of temporary differences between the carrying amounts and tax bases of assets and liabilities using enacted rates. The effect of a change in tax rates on deferred tax assets is recognized in income in the period that includes the enactment date.

Annual tax provisions include amounts considered sufficient to pay assessments that may result from examinations of prior year tax returns; however, the amount ultimately paid upon resolution of issues raised may differ from the amounts accrued.

The Company recognizes the financial statement effects of an uncertain income tax position when it is more likely than not, based on the technical merits, that the position will be sustained upon examination. The Company accrues for other tax contingencies when it is probable that a liability to a taxing authority has been incurred and the amount of the contingency can be reasonably estimated. The current portion of uncertain income tax positions is included in “Income taxes payable” and the long-term portion is included in “Other noncurrent obligations” in the consolidated balance sheets.

Provision is made for taxes on undistributed earnings of foreign subsidiaries and related companies to the extent that such earnings are not deemed to be permanently invested.

Earnings per Common Share

The calculation of earnings per common share is based on the weighted-average number of the Company’s common shares outstanding for the applicable period. The calculation of diluted earnings per common share reflects the effect of all potential dilutive common shares that were outstanding during the respective periods, unless the effect of doing so is antidilutive.

NOTE B – RECENT ACCOUNTING GUIDANCE

Recently Adopted Accounting Guidance

On January 1, 2010, the Company adopted Accounting Standards Update (“ASU”) 2009-16, “Transfers and Servicing (Topic 860): Accounting for Transfers of Financial Assets.” This ASU is intended to improve the information provided in financial statements concerning transfers of financial assets, including the effects of transfers on financial position, financial performance and cash flows, and any continuing involvement of the transferor with the transferred financial assets. The Company evaluated the impact of adopting the guidance and the terms and conditions in place at January 1, 2010 and determined that certain sales of accounts receivable would be classified as secured borrowings. Under the Company’s sale of accounts receivable arrangements, $915 million was outstanding at January 1, 2010. The maximum amount of receivables available for participation in these programs was $1,939 million at January 1, 2010. See Note O for additional information about transfers of financial assets.

On January 1, 2010, the Company adopted ASU 2009-17, “Consolidations (Topic 810): Improvements to Financial Reporting by Enterprises Involved with Variable Interest Entities,” which amended the consolidation guidance applicable to variable interest entities and required additional disclosures concerning an enterprise’s continuing involvement with variable interest entities. The Company evaluated the impact of this guidance and determined that the adoption resulted in the consolidation of two additional joint ventures, an owner trust and an entity that was used to monetize accounts receivable. At January 1, 2010, $793 million in assets (net of tax, including the impact on “Investment in nonconsolidated affiliates”), $941 million in liabilities, $100 million in noncontrolling interests and a cumulative effect adjustment to retained earnings of $248 million were recorded as a result of the adoption of this guidance. See Note S for additional information about variable interest entities.

On January 1, 2010, the Company adopted ASU 2010-06, “Fair Value Measurements and Disclosures (Topic 820): Improving Disclosures about Fair Value Measurements,” which added disclosure requirements about transfers in and out of Levels 1 and 2 and separate disclosures about activity relating to Level 3 measurements and clarifies existing disclosure requirements related to the level of disaggregation and input and valuation techniques. See Note K for additional disclosures about fair value measurements.

Accounting Guidance Issued But Not Adopted as of December 31, 2010

In October 2009, the FASB issued ASU 2009-13, “Revenue Recognition (Topic 605): Multiple-Deliverable Revenue Arrangements – a consensus of the FASB Emerging Issues Task Force,” which amends the criteria for when to evaluate individual delivered items in a multiple deliverable arrangement and how to allocate consideration received. This ASU is effective for fiscal years beginning on or after June 15, 2010. The adoption of the guidance on January 1, 2011 is not expected to have a material impact on the Company’s consolidated financial statements.

NOTE C – RESTRUCTURING

2009 Restructuring

On June 30, 2009, the Company’s Board of Directors approved a restructuring plan related to the Company’s acquisition of Rohm and Haas Company (“Rohm and Haas”) as well as actions to advance the Company’s strategy and to respond to continued weakness in the global economy. The restructuring plan included the elimination of approximately 2,500 positions primarily resulting from synergies to be achieved as a result of the acquisition of Rohm and Haas. In addition, the plan included the shutdown of a number of manufacturing facilities. These actions are expected to be completed primarily by the end of 2011. As a result of the restructuring activities, the Company recorded pretax restructuring charges of $677 million in the second quarter of 2009, consisting of asset write-downs and write-offs of $454 million, costs associated with exit or disposal activities of $68 million and severance costs of $155 million. The impact of the charges is shown as “Restructuring charges” in the consolidated statements of income and was reflected in the Company’s segment results as shown in the following table, which also reflects adjustments made in 2009 to the 2009 plan, the 2008 plan (as discussed below and in the sections titled “2008 Restructuring”) and the 2007 plan.

Details regarding the components of the 2009 restructuring charges and adjustments to restructuring charges are discussed below:

Impairment of Long-Lived Assets and Other Assets

The restructuring charges related to the write-down or write-off of assets totaled $454 million. Write-downs were related to Dow’s facilities located in Hahnville and Plaquemine, Louisiana; the United States Federal Trade Commission (“FTC”) required divestiture of certain acrylic monomer and specialty latex assets in North America; and other small manufacturing facilities where the acquisition of Rohm and Haas resulted in overlapping manufacturing capabilities. Details regarding these write-downs or write-offs are as follows:

• Due to continued weakness in the global economy, the decision was made to shut down a number of hydrocarbon and basic chemicals facilities, with an impact of $126 million, including the following:

◦ Ethylene manufacturing facility in Hahnville, Louisiana. A write-off of the net book value of the related buildings, machinery and equipment against the Feedstocks and Energy segment was recorded. The facility shut down in the second quarter of 2009.

◦ Ethylene oxide/ethylene glycol manufacturing facility in Hahnville, Louisiana. A write-off of the net book value of the related buildings, machinery and equipment against the Feedstocks and Energy segment was recorded. The facility shut down in the second quarter of 2009.

◦ Ethylene dichloride and vinyl chloride monomer manufacturing facility in Plaquemine, Louisiana. A write-down of the net book value of the related buildings, machinery and equipment against the Feedstocks and Energy segment was recorded. The facility will shut down in mid-2011.

• With the completion of the Company’s acquisition of Rohm and Haas, the following charges were recognized:

◦ Due to an expected loss arising from the FTC required divestitures of certain acrylic monomer and specialty latex assets within eight months of the closing of the acquisition of Rohm and Haas, the Company recognized an impairment charge of $205 million against the Coatings and Infrastructure Solutions segment in the second quarter of 2009. The divestiture of the assets was completed in January 2010 (see Note E).

◦ The decision was made to shut down a number of small manufacturing facilities to optimize the assets of the Company. Write-downs of $96 million were recorded in the second quarter of 2009, primarily impacting the Electronic and Functional Materials ($46 million) and Coatings and Infrastructure Solutions ($48 million) segments.

The restructuring charges in the second quarter of 2009 also included the write-off of capital project spending ($20 million) and other assets ($7 million) associated with plant closures. These charges were reflected in the results of the operating segments impacted by the restructuring activities.

Costs Associated with Exit or Disposal Activities

The restructuring charges for costs associated with exit or disposal activities totaled $68 million in the second quarter of 2009 and included environmental remediation of $64 million, impacting Corporate, with the remainder relating to contract termination fees and other charges. In the fourth quarter of 2009, the Company increased the reserve by $13 million to reflect additional expense for pension settlements related to the Rohm and Haas acquisition.

Severance Costs

The restructuring charges included severance of $155 million for the separation of approximately 2,500 employees under the terms of the Company’s ongoing benefit arrangements, primarily over two years. These costs were charged against Corporate. At December 31, 2009, severance of $72 million had been paid and a currency adjusted liability of $84 million remained for approximately 1,221 employees. At December 31, 2010, severance of $149 million had been paid and a currency adjusted liability of $6 million remained for approximately 189 employees, with anticipated departure dates scheduled primarily in the first quarter of 2011.

Dow expects to incur future costs related to its restructuring activities, as the Company continually looks for ways to enhance the efficiency and cost effectiveness of its operations, and to ensure competitiveness across its businesses and across geographic areas. Future costs are expected to include demolition costs related to the closed facilities, which will be recognized as incurred. The Company also expects to incur additional employee-related costs, including involuntary termination benefits, related to its other optimization activities. These costs cannot be reasonably estimated at this time.

2010 Adjustments to 2009 and 2008 Restructuring Plans

In the first quarter of 2010, the Company recorded an additional $8 million charge to adjust the impairment of long-lived assets and other assets related to the FTC required divestitures completed in the first quarter of 2010, and an additional $8 million charge related to the shutdown of a small manufacturing facility under the 2009 restructuring plan. The impact of these charges is shown as “Restructuring charges” in the consolidated statements of income and was reflected in the following operating segments: Electronic and Functional Materials ($8 million) and Coatings and Infrastructure Solutions ($8 million).

In the second quarter of 2010, the Company recorded additional restructuring charges of $13 million, which included the write-off of other assets of $5 million, additional costs associated with exit or disposal activities of $7 million and additional severance of $1 million related to the FTC required divestitures that were included in the 2009 restructuring plan. The impact of these charges is shown as “Restructuring charges” in the consolidated statements of income and was reflected in Coatings and Infrastructure Solutions ($12 million) and Corporate ($1 million).

In the fourth quarter of 2010, the Company decreased the severance reserve for the 2008 restructuring plan by $3 million to adjust the reserve to the remaining future payments. The impact of this adjustment is shown as “Restructuring charges” in the consolidated statements of income and was reflected in Corporate.

2009 Adjustments to 2008 and 2007 Restructuring Plans

In the first quarter of 2009, the Company increased the severance reserve for the 2008 restructuring plan by $19 million, for an additional workforce reduction of approximately 500 employees. The increase was reflected in Corporate.

In the second quarter of 2009, the Company reduced the 2007 restructuring reserve related to contract termination fees by $15 million as a result of the Company’s acquisition of Rohm and Haas, impacting the Agricultural Sciences segment. The initial liability established in 2007 included contract termination fees related to the cancellation of contract manufacturing agreements between the Company and Rohm and Haas. Following completion of the acquisition, the liability for these fees was reversed.

In the fourth quarter of 2009, the Company reduced the severance reserve for the 2007 restructuring plan by $5 million as redeployment opportunities for affected employees were identified. The decrease was reflected in Corporate.

69

Restructuring Reserve Assumed from Rohm and Haas

Included in liabilities assumed in the April 1, 2009 acquisition of Rohm and Haas was a reserve of $122 million for severance and employee benefits for the separation of 1,255 employees under the terms of Rohm and Haas’ ongoing benefit arrangement. The separations resulted from plant shutdowns, production schedule adjustments, productivity improvements and reductions in support services. In the fourth quarter of 2009, the Company decreased the severance reserve assumed from Rohm and Haas by $9 million, recorded in “Cost of sales,” to adjust the reserve to the expected future severance payments. In the nine-month period following the acquisition, severance of $43 million was paid, leaving a currency adjusted liability of $68 million for approximately 552 employees at December 31, 2009.

In the second quarter of 2010, the Company decreased the restructuring reserve $10 million due to the divestiture of the Powder Coatings business and to adjust the reserve to expected future severance payments. In the second half of 2010, the Company decreased the restructuring reserve $24 million to adjust the reserve to expected future severance payments. The impact of these adjustments is shown as “Cost of sales” in the consolidated statements of income and was reflected in Corporate. In 2010, severance of $25 million was paid, leaving a currency adjusted liability of $12 million at December 31, 2010; $5 million for employees who have left the Company and will continue to receive annuity payments primarily through the third quarter of 2011 and $7 million for approximately 44 employees. Cash payments are expected to be complete by mid-2011.

2008 Restructuring

On December 5, 2008, the Company’s Board of Directors approved a restructuring plan as part of a series of actions to advance the Company’s strategy and respond to the severe economic downturn. The restructuring plan included the shutdown of a number of facilities and a global workforce reduction, which were substantially completed in 2010. As a result of the shutdowns and global workforce reduction, the Company recorded pretax restructuring charges of $785 million in the fourth quarter of 2008. The charges consisted of asset write-downs and write-offs of $336 million, costs associated with exit or disposal activities of $128 million and severance costs of $321 million. The impact of the charges is shown as “Restructuring charges” in the consolidated statements of income and was reflected in the Company’s segment results as shown in the following table, which also reflects adjustments made in 2008 to the 2007 and 2006 restructuring charges.

Details regarding the components of the 2008 restructuring charges are discussed below:

Impairment of Long-Lived Assets and Other Assets

The restructuring charges related to the write-down or write-off of assets in 2008 totaled $336 million and included the impact of plant closures and impairments of $288 million. The most significant write-downs were related to Dow’s facilities located in Oyster Creek, Freeport, Seadrift and Texas City, Texas; Pittsburg, California; Terneuzen, The Netherlands; Varennes, Quebec, Canada; Plaquemine, Louisiana; Aratu, Brazil; King’s Lynn and Wilton, England; assets related to the pending sale of the automotive sealants business in Europe; and project investment costs related to a potential joint venture in Oman. Details regarding these write-downs or write-offs are as follows:

• Due to a severe economic downturn, the Company decided in the fourth quarter of 2008 to shut down a number of facilities, including the following:

◦ Chlor-alkali manufacturing facility in Oyster Creek, Texas. A $31 million write-off of the net book value of the related buildings, machinery and equipment against the Feedstocks and Energy segment was recorded in the fourth quarter of 2008. This facility was shut down in the first quarter of 2009.

◦ Styrene and styrene derivatives manufacturing facilities principally in Freeport, Texas; Pittsburg, California; Terneuzen, The Netherlands; King’s Lynn, England; and Varennes, Canada. A $37 million write-off of the net book value of the related buildings, machinery and equipment was recorded in the fourth quarter of 2008 against the Feedstocks and Energy ($14 million), Performance Plastics ($6 million), Performance Materials ($10 million) and Coatings and Infrastructure Solutions ($2 million) segments, as well as Corporate ($5 million). The facilities were shut down in the fourth quarter of 2009.

◦ Facilities that manufacture NORDEL^TM hydrocarbon rubber in Seadrift, Texas, and TYRIN^TM chlorinated polyethylene in Plaquemine, Louisiana. A $36 million write-down of the net book value of the related buildings, machinery and equipment against the Performance Plastics ($22 million) and Performance Materials ($14 million) segments was recorded in the fourth quarter of 2008. Both facilities were closed in the first quarter of 2009.

◦ Solution vinyl resin manufacturing facilities in Texas City, Texas. A $26 million write-down of the net book value of the related buildings, machinery and equipment against the Performance Materials segment was recorded in the fourth quarter of 2008. This plant was shut down in the third quarter of 2009.

◦ Perchloroethylene/carbon tetrachloride manufacturing facility in Aratu, Brazil. An $11 million write-off of the net book value of the related buildings, machinery and equipment against the Performance Materials segment was recorded in the fourth quarter of 2008. This facility was closed in the second quarter of 2010.

71

◦ In addition to the locations described above, the restructuring charges for plant closures included $26 million related to the shutdown of several small production facilities.

• The Company decided in the fourth quarter of 2008 to pursue strategic alternatives regarding its Wilton, England, ethylene oxide/ethylene glycol (“EO/EG”) plant. Based on the results of asset impairment testing, an impairment charge of $30 million against the Feedstocks and Energy segment was recorded in the fourth quarter of 2008. The plant was shut down in January 2010.

• Due to an expected loss on the pending sale of the automotive sealants business in Europe, an impairment charge of $8 million against the Performance Materials segment was recorded in the fourth quarter of 2008. The business was sold in the first quarter of 2009.

• Due to a change in scope, the Company’s investment (primarily engineering costs) in a project to form a joint venture to design, build and operate a petrochemical complex in Oman was written down. An $83 million write-down of the project-related spending against the Performance Plastics segment was recorded in the fourth quarter of 2008.

The restructuring charges in the fourth quarter of 2008 also included the write-off of capital project spending ($13 million); spare parts ($9 million) and catalysts ($6 million) associated with plant closures; other assets ($5 million); as well as a loss on the sale of inventory ($15 million) associated with the divestiture of the automotive sealants business in Europe. These write-offs were related to the businesses involved in the shutdown of assets and were therefore reflected in the results of various operating segments.

Costs Associated with Exit or Disposal Activities

The restructuring charges for costs associated with exit or disposal activities totaled $128 million in 2008 and included pension curtailment costs and termination benefits of $88 million reflected in Corporate; and environmental remediation and asbestos abatement of $40 million primarily impacting Performance Materials and Corporate.

Severance Costs

As a result of the Company’s decision to shut down assets around the world and implement a global workforce reduction, the restructuring charges included severance of $321 million for the separation of approximately 3,000 employees under the terms of Dow’s ongoing benefit arrangements. These costs were charged against Corporate. In the first quarter of 2009, the Company increased the severance reserve by $19 million, including approximately 500 additional employees. At December 31, 2009, severance of $289 million had been paid and a currency adjusted liability of $53 million remained for approximately 293 employees. In the fourth quarter of 2010, the Company decreased the severance reserve by $3 million to adjust the reserve to the remaining future payments. The impact of this adjustment is shown as “Restructuring charges” in the consolidated statements of income and was reflected in Corporate. At December 31, 2010, severance of $316 million had been paid and employee separations were substantially complete. A currency adjusted liability of $22 million remained at December 31, 2010, largely for employees who have left the Company and will continue to receive annuity payments primarily through 2018.

The shutdowns and optimization activities related to the 2008 restructuring plan were substantially complete in 2010, with remaining liabilities primarily related to pension, environmental remediation and severance to be paid over time.

2008 Adjustments to 2007 and 2006 Restructuring Plans

In 2008, adjustments were made to the 2007 restructuring plan to increase the reserve for environmental remediation $5 million (impacting Corporate). The 2007 restructuring reserve was also increased $5 million for contract termination fees, reflected in Performance Materials ($2 million) and Agricultural Sciences ($3 million). In the fourth quarter of 2008, Pétromont, a nonconsolidated affiliate, announced the permanent shutdown of its operations. As a result of this announcement, the Company recorded an additional charge of $50 million against the 2007 restructuring plan (impacting the Performance Plastics segment).

In 2008, adjustments were made to the 2006 restructuring plan to decrease the reserve for environmental remediation $3 million (impacting the Feedstocks and Energy segment) and to decrease the severance reserve $3 million (impacting Corporate).

NOTE D – ACQUISITIONS

Acquisition of Rohm and Haas

On April 1, 2009, the Company completed the acquisition of Rohm and Haas. Pursuant to the July 10, 2008 Agreement and Plan of Merger (the “Merger Agreement”), Ramses Acquisition Corp., a direct wholly owned subsidiary of the Company, merged with and into Rohm and Haas (the “Merger”), with Rohm and Haas continuing as the surviving corporation and becoming a direct wholly owned subsidiary of the Company.

The Company pursued the acquisition of Rohm and Haas to make the Company a leading specialty chemicals and advanced materials company, combining the two organizations’ best-in-class technologies, broad geographic reach and strong industry channels to create a business portfolio with significant growth opportunities.

Pursuant to the terms and conditions of the Merger Agreement, each outstanding share of Rohm and Haas common stock was converted into the right to receive cash of $78 per share, plus additional cash consideration of $0.97 per share. The additional cash consideration represented 8 percent per annum on the $78 per share consideration from January 10, 2009 to the closing of the Merger, less dividends declared by Rohm and Haas with a dividend record date between January 10, 2009 and the closing of the Merger. All options to purchase shares of common stock of Rohm and Haas granted under the Rohm and Haas stock option plans and all other Rohm and Haas equity-based compensation awards, whether vested or unvested as of April 1, 2009, became fully vested and converted into the right to receive cash of $78.97 per share, less any applicable exercise price. Total cash consideration paid to Rohm and Haas shareholders was $15,681 million. As part of the purchase price, $552 million in cash was paid to the Rohm and Haas Company Employee Stock Ownership Plan (“Rohm and Haas ESOP”) on April 1, 2009 for 7.0 million shares of Rohm and Haas common stock held by the Rohm and Haas ESOP.

73

As a condition of the FTC’s approval of the Merger, the Company was required to divest a portion of its acrylic monomer business, a portion of its specialty latex business and its hollow sphere particle business. The Company completed the sale of these businesses in 2010 (see Note E). Total net sales and cost of sales for these businesses amounted to approximately one percent of the Company’s 2008 net sales and cost of sales.

The following table provides net sales and results of operations from the Rohm and Haas acquired businesses included in the Company’s 2009 results since the April 1, 2009 acquisition. Included in the results from Rohm and Haas was $257 million of restructuring charges (see Note C), a one-time increase in cost of sales of $209 million related to the fair value step-up of inventories acquired from Rohm and Haas and sold in the second quarter of 2009 and a pretax loss of $56 million on the early extinguishment of debt.

The following table provides pro forma net sales and results of operations for the years ended December 31, 2009 and December 31, 2008, as if Rohm and Haas had been acquired on January 1 of each year. The unaudited pro forma results reflect certain adjustments related to the acquisition, such as increased depreciation and amortization expense on assets acquired from Rohm and Haas resulting from the fair valuation of assets acquired and the impact of acquisition financing in place at December 31, 2009. The pro forma results do not include any anticipated cost synergies or other effects of the planned integration of Rohm and Haas. Accordingly, such pro forma amounts are not necessarily indicative of the results that actually would have occurred had the acquisition been completed on the dates indicated, nor are they indicative of the future operating results of the combined company.

The following table summarizes the fair values of the assets acquired and liabilities assumed from Rohm and Haas on April 1, 2009. During the measurement period, which ended on March 31, 2010, net adjustments of $145 million were made to the fair values of the assets acquired and liabilities assumed with a corresponding adjustment to goodwill. These adjustments are summarized in the table presented below. The balance sheet at December 31, 2009 has been retrospectively adjusted to reflect these adjustments as required by the accounting guidance for business combinations. No further adjustments have been made to the acquisition-date fair values of assets acquired and liabilities assumed since the end of the measurement period.

The fair value of receivables acquired from Rohm and Haas on April 1, 2009 (net of the Salt business) was $1,001 million, with gross contractual amounts receivable of $1,048 million. Liabilities assumed from Rohm and Haas on April 1, 2009 included certain contingent environmental liabilities valued at $159 million and a liability of $185 million related to Rohm and Haas Pension Plan matters (see Note N), which were valued in accordance with the accounting guidance for contingencies. Operating loss carryforwards of $2,189 million were acquired from Rohm and Haas on April 1, 2009, $137 million of which were subject to expiration in 2009 through 2013.

The following table summarizes the major classes of assets and liabilities underlying the deferred tax liabilities resulting from the acquisition of Rohm and Haas:

Deferred Tax Liabilities Assumed on April 1, 2009 In millions	As Adjusted
Intangible assets	$	1,754
Property	526
Long-term debt	191
Inventory	80
Other accruals and reserves	324
Total Deferred Tax Liabilities	$	2,875

The acquisition resulted in the recognition of $9,707 million of goodwill, which is not deductible for tax purposes. See Note I for further information on goodwill, including the allocation by segment.

Goodwill largely consists of expected synergies resulting from the acquisition. Key areas of cost savings include increased purchasing power for raw materials; manufacturing and supply chain work process improvements; and the elimination of redundant corporate overhead for shared services and governance. The Company also anticipates that the transaction will produce significant growth synergies through the application of each company’s innovative technologies and through the combined businesses’ broader product portfolio in key industry segments with strong global growth rates.

Financing for the Rohm and Haas Acquisition

Financing for the acquisition of Rohm and Haas included debt and equity financing (see Notes P, W and X).

Rohm and Haas Acquisition and Integration Related Expenses

During 2010, pretax charges totaling $143 million were recorded for integration expenses related to the April 1, 2009 acquisition of Rohm and Haas. During 2009, pretax charges totaling $166 million ($49 million in 2008) were recorded for legal expenses and other transaction and integration costs related to the acquisition. These charges, which were expensed in accordance with the accounting guidance for business combinations, were recorded in “Acquisition and integration related expenses” and reflected in Corporate. An additional $60 million of acquisition-related retention expenses were incurred during 2009 and recorded in “Cost of sales,” “Research and development expenses,” and “Selling, general and administrative expenses” and reflected in Corporate.

Purchased In-Process Research and Development

Purchased in-process research and development (“IPR&D”) represents the value assigned to acquired research and development projects that, as of the date of the acquisition, had not established technological feasibility and had no alternative future use. Prior to January 1, 2009, amounts assigned to IPR&D meeting these criteria were charged to expense as part of the allocation of the purchase price of the business combination. With the adoption of ASC Topic 805, “Business Combinations,” on January 1, 2009, IPR&D acquired in a business combination is capitalized and tested for impairment annually.

The Company recorded pretax charges totaling $7 million in 2009 for IPR&D projects associated with the purchase of technology that was not part of a business combination. The Company recorded pretax charges totaling $44 million in 2008 for IPR&D projects associated with several acquisitions. The estimated values assigned to the IPR&D projects were determined primarily based on a discounted cash flow model and are shown below:

In-Process Research and Development Projects Acquired In millions	Date of Acquisition	Estimated   Value Assigned   to IPR&D
2009
Lithium ion battery technology purchase	October 30, 2009	$	7
2008
Germplasm from Triumph Seed Co., Inc.	February 29, 2008	$	4
Germplasm from Dairyland Seed Co., Inc. and Bio-Plant Research Ltd.	August 29, 2008	23
Germplasm from Südwestsaat GbR	December 16, 2008	17
Total 2008 IPR&D		$	44

The IPR&D charges outlined above are shown as “Purchased in-process research and development charges” in the consolidated statements of income. The 2009 IPR&D charges related to a technology purchase for projects within the Ventures business, impacting Corporate. The 2008 IPR&D charges were related to projects within the Agricultural Sciences segment.

NOTE E – DIVESTITURES

Divestiture of the Styron Business Unit

On March 2, 2010, the Company announced the entry into a definitive agreement to sell the Styron business unit (“Styron”) to an affiliate of Bain Capital Partners. The definitive agreement specified the assets and liabilities related to the businesses and products to be included in the sale. On June 17, 2010, the sale was completed for $1,561 million, net of working capital adjustments and costs to sell, with proceeds subject to customary post-closing adjustments. The proceeds included a $75 million long-term note receivable. In addition, the Company elected to acquire a 7.5 percent equity interest in the resulting privately held, global materials company. Businesses and products sold included: Styrenics – polystyrene, acrylonitrile butadiene styrene, styrene acrylonitrile and expandable polystyrene; Emulsion Polymers; Polycarbonate and Compounds and Blends; Synthetic Rubber; and certain products from Dow Automotive Systems. Also included in the sale were certain styrene monomer assets and the Company’s 50 percent ownership interest in Americas Styrenics LLC, a nonconsolidated affiliate. The transaction also resulted in several long-term supply, service and purchase agreements between Dow and Styron.

76

Styron’s results of operations were not classified as discontinued operations, as the Company has continuing cash flows as a result of the supply, service and purchase agreements, and continues to hold an equity interest.

The following table presents the major classes of assets and liabilities divested by operating segment:

Styron Assets and Liabilities Divested on June 17, 2010 In millions	Perf Materials		Perf Plastics		Feedstocks and Energy		Corp			Total

Post-closing adjustments were finalized in the fourth quarter of 2010. In 2010, the Company recognized a pretax gain of $27 million on the sale, net of post-closing adjustments of $24 million and including a net gain on the sale of two small, related joint ventures, working capital adjustments and additional costs to sell. The net gain was included in “Sundry income – net” and reflected in the following operating segments: Performance Materials ($20 million) and Performance Plastics ($7 million). The sale resulted in an after-tax loss of $56 million, primarily because goodwill related to the divestiture was not tax deductible.

On February 3, 2011, Styron repaid the $75 million long-term note receivable, plus interest.

Divestitures Required as a Condition to the Acquisition of Rohm and Haas

As a condition of the FTC’s approval of the April 1, 2009 acquisition of Rohm and Haas, the Company was required to divest a portion of its acrylic monomer business, a portion of its specialty latex business and its hollow sphere particle business. As a result, the Company recognized an impairment charge of $205 million related to these assets in the second quarter of 2009 restructuring charge (see Note C).

On July 31, 2009, the Company entered into a definitive agreement that included the sale of the portion of its acrylic monomer business and the portion of its specialty latex business. The sale was completed on January 25, 2010. Additional impairment charges of $8 million related to these assets were recognized in the first quarter of 2010. In the second quarter of 2010, additional severance costs of $1 million and the write-off of other assets of $5 million were recognized (see Note C).

The Company completed the sale of its hollow sphere particle business in the second quarter of 2010 and recognized additional costs associated with disposal activities of $7 million, related to contract termination fees (see Note C).

Divestiture of the Rohm and Haas Salt Business

On April 1, 2009, the Company announced the entry into a definitive agreement to sell the stock of Morton International, Inc. (“Morton”), the Salt business of Rohm and Haas, to K+S Aktiengesellschaft (“K+S”). On October 1, 2009, the Company completed the divestiture of its interest in Morton to K+S and received net proceeds of $1,576 million, with proceeds subject to customary post-closing adjustments. As a result, the Company recognized a pretax $37 million gain on the sale in the fourth quarter of 2009, included in “Sundry income – net,” and reflected in Corporate. One billion dollars in proceeds from this transaction were used to pay off the Term Loan Agreement used to fund the acquisition of Rohm and Haas (see Note P). The results of operations for the Salt business were reported in Corporate and were not material to the consolidated financial statements.

On September 1, 2009, the Company completed the sale of its ownership interest in Total Raffinaderij Nederland N.V. (“TRN”), a nonconsolidated affiliate, and related inventory to Total S.A. for $742 million. This sale resulted in a pretax net gain of $457 million, which consisted of a gain of $513 million reflected in “Sundry income – net” and a charge of $56 million related to the recognition of hedging losses which were recorded to “Cost of sales.” The gain impacted the Feedstocks and Energy segment.

On September 30, 2009 the Company completed the sale of its ownership interest in the OPTIMAL Group of Companies (“OPTIMAL”), nonconsolidated affiliates, to Petroliam Nasional Berhad for net proceeds of $660 million.

NOTE H – NONCONSOLIDATED AFFILIATES AND RELATED COMPANY TRANSACTIONS

The Company’s investments in related companies accounted for using the equity method (“nonconsolidated affiliates”) were $3,453 million at December 31, 2010 and $3,224 million at December 31, 2009. At December 31, 2010, the carrying amount of the Company’s investments in nonconsolidated affiliates was $74 million more than its share of the investees’ net assets, exclusive of additional differences for Dow Corning Corporation (“Dow Corning”), MEGlobal and Equipolymers, which are discussed separately below. At December 31, 2009, the carrying amount of the Company’s investments in nonconsolidated affiliates was $52 million more than its share of the investees’ net assets, exclusive of additional differences for Dow Corning, MEGlobal, Equipolymers and Americas Styrenics LLC. Dividends received from the Company’s nonconsolidated affiliates were $668 million in 2010, $690 million in 2009 and $836 million in 2008.

On May 15, 1995, Dow Corning, in which the Company is a 50 percent shareholder, voluntarily filed for protection under Chapter 11 of the U.S. Bankruptcy Code (see Note N). As a result, the Company fully reserved its investment in Dow Corning and reserved its 50 percent share of equity earnings from that time through the third quarter of 2000. In November 2000, following affirmation of the Bankruptcy Court’s order confirming the Joint Plan of Reorganization (the “Joint Plan”), the Company reviewed the value of its investment in Dow Corning, revised its assessment of the recoverability of its investment, and determined that it had adequately provided for the other-than-temporary decline associated with the bankruptcy. On June 1, 2004, Dow Corning’s Joint Plan became effective and Dow Corning emerged from bankruptcy. Since May 1995, a difference between the Company’s 50 percent share of the underlying equity of Dow Corning and the carrying value of this investment has existed, and the Company considers the difference to be permanent. The Company’s investment in Dow Corning was $227 million less than the Company’s proportionate share of Dow Corning’s underlying net assets at December 31, 2010 and December 31, 2009.

At December 31, 2010, the Company’s investment in MEGlobal was $250 million less than the Company’s proportionate share of MEGlobal’s underlying net assets ($257 million less at December 31, 2009). This amount represents the difference between the value of certain assets of the joint venture and the Company’s related valuation on a U.S. GAAP basis, of which $60 million is being amortized over the remaining useful lives of the assets and $190 million represents the Company’s share of the joint venture’s goodwill.

79

At December 31, 2010, the Company’s investment in Equipolymers was $7 million less than the Company’s proportionate share of Equipolymers’ underlying net assets ($8 million less at December 31, 2009). This amount represents the difference between the value of certain assets of the joint venture and the Company’s related valuation on a U.S. GAAP basis, all of which is being amortized over the remaining useful lives of the assets. In the fourth quarter of 2009, the Company recognized an impairment loss of $65 million related to its investment in Equipolymers.

At December 31, 2009, the Company’s investment in Americas Styrenics LLC was $136 million less than the Company’s proportionate share of Americas Styrenics LLC’s underlying net assets. This amount represented the difference between the book value of assets contributed to the joint venture by the Company at the time of formation (May 1, 2008) and the Company’s 50 percent share of the total recorded value of the joint venture’s assets. The Company’s investment in Americas Styrenics LLC was sold on June 17, 2010, as part of the divestiture of Styron (see Note E).

See Note E for information regarding the divestiture of the Company’s investment in two additional nonconsolidated affiliates in 2009.

All of the nonconsolidated affiliates in which the Company has investments are privately held companies; therefore, quoted market prices are not available.

The recording of the April 1, 2009 acquisition of Rohm and Haas (see Note D) resulted in goodwill of $9,707 million, which is not deductible for tax purposes. During the first quarter of 2010, goodwill related to the acquisition of Rohm and Haas increased $99 million for net adjustments made during the measurement period to the fair values of the assets acquired and liabilities assumed. In the table above, these adjustments have been retrospectively reflected in the goodwill at January 1, 2010, in accordance with the accounting guidance for business combinations. The adjustments increased goodwill for the operating segments as follows: Electronic and Functional Materials ($33 million), Coatings and Infrastructure Solutions ($47 million), Agricultural Sciences ($2 million), Performance Materials ($4 million) and Performance Plastics ($13 million).

As a result of the June 17, 2010 divestiture of Styron, $141 million of associated goodwill and $16 million of intangible assets were divested (see Note E). On June 1, 2010, the Company divested its Powder Coatings business, including $4 million of associated goodwill, and on October 1, 2010, the Company divested its Hydrocarbon Resins business, including $9 million of associated goodwill.

Goodwill Impairments

During the fourth quarter of 2010, the Company performed its annual impairment tests for goodwill. As a result of this review, it was determined that no additional goodwill impairments existed.

During the fourth quarter of 2009, the Company performed its annual impairment tests for goodwill. As a result of this review, it was determined that the goodwill associated with the Dow Haltermann reporting unit was impaired. The impairment was based on a review of the Dow Haltermann reporting unit performed by management, in which discounted cash flows did not support the carrying value of the goodwill due to poor future projections for the business. As a result, an impairment loss of $7 million was recognized in the fourth quarter of 2009 against the Performance Materials segment.

During the fourth quarter of 2008, the Company performed its annual impairment tests for goodwill. As a result of this review, it was determined that the goodwill associated with the Dow Automotive Systems reporting unit was impaired. The impairment was based on a review of the Dow Automotive Systems reporting unit performed by management, in which discounted cash flows did not support the carrying value of the goodwill due to the severe downturn in the automotive industry and the future projections for the business. As a result, an estimated impairment loss of $209 million was recognized in the fourth quarter of 2008 against the Performance Materials segment. The second step of goodwill impairment testing to determine the implied fair value of goodwill for the Dow Automotive Systems reporting unit was finalized in the first quarter of 2009. No adjustment was required to be made to the estimated impairment loss based on completion of the allocation process.

82

Also as a result of the 2008 annual tests, it was determined that the goodwill associated with the Polypropylene reporting unit was impaired. The impairment was based on a review of the Polypropylene reporting unit performed by management, in which discounted cash flows did not support the carrying value of the goodwill due to demand decline in North America and Western Europe, as well as significant new industry capacity that came on stream in 2008 and additional industry capacity that was expected in 2009. As a result, an impairment loss of $30 million was recognized in the fourth quarter of 2008 against the Performance Plastics segment.

At December 31, 2010, the Company had $3,200 million of held-to-maturity securities (primarily Treasury Bills) classified as cash equivalents, as these securities had original maturities of three months or less. At December 31, 2009, the Company had no such securities. The Company’s investments in held-to-maturity securities are held at amortized cost, which approximates fair value. At December 31, 2010, the Company had investments in money market funds of $35 million classified as cash equivalents ($164 million at December 31, 2009).

The net unrealized gain recognized during 2010 on trading securities held at December 31, 2010 was $14 million ($7 million at December 31, 2009).

Portfolio managers regularly review the Company’s holdings to determine if any investments are other-than-temporarily impaired. The analysis includes reviewing the amount of the impairment, as well as the length of time it has been impaired. In addition, specific guidelines for each instrument type are followed to determine if an other-than-temporary impairment has occurred.

For debt securities, the credit rating of the issuer, current credit rating trends, the trends of the issuer’s overall sector, the ability of the issuer to pay expected cash flows and the length of time the security has been in a loss position are considered in determining whether unrealized losses represent an other-than-temporary impairment. The Company did not have any credit-related losses during 2010 or 2009.

For equity securities, the Company’s investments are primarily in Standard & Poor’s (“S&P”) 500 companies; however, the Company’s policies allow investments in companies outside of the S&P 500. The largest holdings are Exchange Traded Funds that represent the S&P 500 index or an S&P 500 sector or subset. The Company considers the evidence to support the recovery of the cost basis of a security including volatility of the stock, the length of time the security has been in a loss position, value and growth expectations, and overall market and sector fundamentals, as well as technical analysis, in determining whether unrealized losses represent an other-than-temporary impairment. In 2010, other-than-temporary impairment write-downs on investments still held by the Company were $5 million ($93 million in 2009).

The aggregate cost of the Company's cost method investments totaled $171 million at December 31, 2010 ($129 million at December 31, 2009). Due to the nature of these investments, the fair market value is not readily determinable. These investments are reviewed for impairment indicators. During 2010, the Company's impairment analysis identified indicators that resulted in a reduction in the cost basis of these investments of $16 million; the analysis resulted in a reduction of $10 million for the year ended December 31, 2009.

Risk Management

Dow’s business operations give rise to market risk exposure due to changes in interest rates, foreign currency exchange rates, commodity prices and other market factors such as equity prices. To manage such risks effectively, the Company enters into hedging transactions, pursuant to established guidelines and policies, which enable it to mitigate the adverse effects of financial market risk. Derivatives used for this purpose are designated as cash flow, fair value or net foreign investment hedges where appropriate. The guidance requires companies to recognize all derivative instruments as either assets or liabilities at fair value. A secondary objective is to add value by creating additional nonspecific exposures within established limits and policies; derivatives used for this purpose are not designated as hedges. The potential impact of creating such additional exposures is not material to the Company’s results.

The Company’s risk management program for interest rate, foreign currency and commodity risks is based on fundamental, mathematical and technical models that take into account the implicit cost of hedging. Risks created by derivative instruments and the mark-to-market valuations of positions are strictly monitored at all times, using value at risk and stress tests. Credit risk arising from these contracts is not significant because the Company minimizes counterparty concentration, deals primarily with major financial institutions of solid credit quality, and the majority of its hedging transactions mature in less than three months. In addition, the Company minimizes concentrations of credit risk through its global orientation in diverse businesses with a large number of diverse customers and suppliers. It is the Company’s policy not to have credit-risk-related contingent features in its derivative instruments. The Company does not anticipate losses from credit risk and the net cash requirements arising from counterparty risk associated with risk management activities are not expected to be material in 2011. No significant concentration of credit risk existed at December 31, 2010.

The Company reviews its overall financial strategies and the impacts from using derivatives in its risk management program with the Company’s Board of Directors and revises its strategies as market conditions dictate.

Interest Rate Risk Management

The Company enters into various interest rate contracts with the objective of lowering funding costs or altering interest rate exposures related to fixed and variable rate obligations. In these contracts, the Company agrees with other parties to exchange, at specified intervals, the difference between fixed and floating interest amounts calculated on an agreed-upon notional principal amount. At December 31, 2010, the Company had no open interest rate swaps.

Foreign Currency Risk Management

The Company’s global operations require active participation in foreign exchange markets. The Company enters into foreign exchange forward contracts and options, and cross-currency swaps to hedge various currency exposures or create desired exposures. Exposures primarily relate to assets, liabilities and bonds denominated in foreign currencies, as well as economic exposure, which is derived from the risk that currency fluctuations could affect the dollar value of future cash flows related to operating activities. The primary business objective of the activity is to optimize the U.S. dollar value of the Company’s assets,

86

liabilities and future cash flows with respect to exchange rate fluctuations. Assets and liabilities denominated in the same foreign currency are netted, and only the net exposure is hedged. At December 31, 2010, the Company had forward contracts, options and cross-currency swaps to buy, sell or exchange foreign currencies. These contracts had various expiration dates, primarily in the first quarter of 2011.

Commodity Risk Management

The Company has exposure to the prices of commodities in its procurement of certain raw materials. The primary purpose of commodity hedging activities is to manage the price volatility associated with these forecasted inventory purchases. At December 31, 2010, the Company had futures contracts, options and swaps to buy, sell or exchange commodities. These agreements had various expiration dates primarily in 2011.

Accounting for Derivative Instruments and Hedging Activities

Cash Flow Hedges

For derivatives that are designated and qualify as cash flow hedging instruments, the effective portion of the gain or loss on the derivative is recorded in “Accumulated other comprehensive income (loss)” (“AOCI”); it is reclassified to “Cost of sales” in the same period or periods that the hedged transaction affects income. The unrealized amounts in AOCI fluctuate based on changes in the fair value of open contracts at the end of each reporting period. The Company anticipates volatility in AOCI and net income from its cash flow hedges. The amount of volatility varies with the level of derivative activities and market conditions during any period. Gains and losses on the derivative representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness are recognized in current period income.

The net loss from previously terminated interest rate cash flow hedges included in AOCI at December 31, 2010 was $2 million after tax ($2 million after tax at December 31, 2009). During 2010, 2009 and 2008, there was no material impact on the consolidated financial statements due to interest rate hedge ineffectiveness. The Company had no open interest rate derivatives at December 31, 2010 (notional U.S. dollar equivalent of $30 million at December 31, 2009).

Current open foreign currency forward contracts hedge the currency risk of forecasted feedstock purchase transactions until April 2011. The effective portion of the mark-to-market effects of the foreign currency forward contracts is recorded in AOCI; it is reclassified to income in the same period or periods that the underlying feedstock purchase affects income. The net loss from the foreign currency hedges included in AOCI at December 31, 2010 was $4 million after tax (net loss of $5 million after tax at December 31, 2009). During 2010, 2009 and 2008, there was no material impact on the consolidated financial statements due to foreign currency hedge ineffectiveness. At December 31, 2010, the Company had open forward contracts with various expiration dates to buy, sell or exchange foreign currencies with a notional U.S. dollar equivalent of $827 million ($645 million at December 31, 2009).

Commodity swaps, futures and option contracts with maturities of not more than 36 months are utilized and designated as cash flow hedges of forecasted commodity purchases. Current open contracts hedge forecasted transactions until December 2011. The effective portion of the mark-to-market effect of the cash flow hedge instrument is recorded in AOCI; it is reclassified to income in the same period or periods that the underlying commodity purchase affects income. Due to the September 1, 2009 sale of TRN, the Company recognized a pretax loss of $56 million for cash flow hedges of forecasted purchases that will not occur as a result of the sale (see Note E). The net gain from commodity hedges included in AOCI at December 31, 2010 was $3 million after tax (zero at December 31, 2009). During 2010, 2009 and 2008, there was no material impact on the consolidated financial statements due to commodity hedge ineffectiveness. At December 31, 2010 and 2009, the Company had the following aggregate notionals of outstanding commodity forward contracts to hedge forecasted purchases:

Commodity	2010	2009	Notional Volume Unit
Crude Oil	0.1	0.7	million barrels
Ethane	1.6	—	million barrels
Naphtha	—	50	kilotons
Natural Gas	2.7	2.0	million million British thermal units

Fair Value Hedges

For derivative instruments that are designated and qualify as fair value hedges, the gain or loss on the derivative as well as the offsetting loss or gain on the hedged item attributable to the hedged risk are recognized in current period income and reflected as “Interest expense and amortization of debt discount” in the consolidated statements of income. The short-cut method is used when the criteria are met. The Company had no open interest rate swaps designated as fair value hedges of underlying fixed rate debt obligations at December 31, 2010 and 2009.

87

Net Foreign Investment Hedges

For derivative instruments that are designated and qualify as net foreign investment hedges, the effective portion of the gain or loss on the derivative is included in “Cumulative Translation Adjustments” in AOCI. The results of hedges of the Company’s net investment in foreign operations included in “Cumulative Translation Adjustments” in AOCI was a net gain of $70 million after tax at December 31, 2010 (net loss of $56 million after tax at December 31, 2009). During 2010, 2009 and 2008 there was no material impact on the consolidated financial statements due to hedge ineffectiveness. At December 31, 2010 and 2009, the Company had no open forward contracts or outstanding options to buy, sell or exchange foreign currencies. At December 31, 2010, the Company had outstanding foreign-currency denominated debt designated as a hedge of net foreign investment of $1,250 million ($1,879 million at December 31, 2009).

Other Derivative Instruments

The Company utilizes futures, options and swap instruments that are effective as economic hedges of commodity price exposures, but do not meet the hedge accounting criteria in the accounting guidance for derivatives and hedging. At December 31, 2010 and 2009, the Company had the following aggregate notionals of outstanding commodity contracts:

Commodity	2010	2009	Notional Volume Unit
Ethane	3.8	0.9	million barrels
Natural Gas	12.0	2.8	million million British thermal units

The Company also uses foreign exchange forward contracts, options, and cross-currency swaps that are not designated as hedging instruments primarily to manage foreign currency and interest rate exposure. The Company had open foreign exchange contracts with various expiration dates to buy, sell or exchange foreign currencies and a notional U.S. dollar equivalent of $13,944 million at December 31, 2010 ($15,312 million at December 31, 2009).

(1) Cash collateral is classified as “Accounts and notes receivable – Other” in the consolidated balance sheets. Amounts represent the estimated net settlement amount when applying netting and set-off rights included in master netting arrangements between the Company and its counterparties and the payable or receivable for cash collateral held or placed with the same counterparty.

(2) Included in “Accounts and notes receivable – Other” in the consolidated balance sheets. See Note O for additional information on transfers of financial assets.

(3) The Company’s investments in equity and debt securities are primarily classified as available-for-sale and are included in “Other investments” in the consolidated balance sheets.

(4) U.S. Treasury obligations, U.S. agency obligations, agency mortgage-backed securities and other municipalities’ obligations.

(5) See Note J for the classification of derivatives in the consolidated balance sheets.

90

Assets and liabilities related to forward contracts, interest rate swaps, currency swaps, options and other conditional or exchange contracts executed with the same counterparty under a master netting arrangement are netted. Collateral accounts are netted with corresponding assets and liabilities. The Company posted cash collateral of $4 million at December 31, 2010, classified as “Accounts and notes receivable – Other” in the consolidated balance sheets.

For assets and liabilities classified as Level 1 measurements (measured using quoted prices in active markets), total fair value is either the price of the most recent trade at the time of the market close or the official close price, as defined by the exchange on which the asset is most actively traded on the last trading day of the period, multiplied by the number of units held without consideration of transaction costs.

For assets and liabilities classified as Level 2 measurements, where the security is frequently traded in less active markets, fair value is based on the closing price at the end of the period; where the security is less frequently traded, fair value is based on the price a dealer would pay for the security or similar securities, adjusted for any terms specific to that asset or liability. Market inputs are obtained from well-established and recognized vendors of market data and subjected to tolerance/quality checks. For derivative assets and liabilities, standard industry models are used to calculate the fair value of the various financial instruments based on significant observable market inputs, such as foreign exchange rates, commodity prices, swap rates, interest rates and implied volatilities obtained from various market sources.

For all other assets and liabilities for which observable inputs are used, fair value is derived through the use of fair value models, such as a discounted cash flow model or other standard pricing models. See Note J for further information on the types of instruments used by the Company for risk management.

There were no significant transfers between Levels 1 and 2 during the year ended December 31, 2010.

For assets classified as Level 3 measurements, fair value is based on significant unobservable inputs including assumptions where there is little, if any, market activity. The fair value of the Company’s interests held in trade receivable conduits is determined by calculating the expected amount of cash to be received using the key input of anticipated credit losses in the portfolio of receivables sold that have not yet been collected (1.42 percent for North America and zero for Europe at December 31, 2010). Given the short-term nature of the underlying receivables, discount rate and prepayments are not factors in determining the fair value of the interests. See Note O for further information on assets classified as Level 3 measurements.

The following table summarizes the changes in fair value measurements using Level 3 inputs for the year ended December 31, 2010:

After evaluating expected future investments in conjunction with expected future cash flows, a $48 million asset impairment charge was recognized in the Polyurethanes business in the fourth quarter of 2010. The Company’s evaluation of strategic alternatives for Epoxy capacity resulted in an $18 million asset impairment charge in the fourth quarter of 2010. Due to a change in the scope of a capital project, a $9 million asset impairment charge was recognized in Dow Automotive Systems in the fourth quarter of 2010. In all cases, the assets were written down to zero. The charges were included in “Cost of sales” in the consolidated statements of income and reflected in the Performance Materials ($75 million) segment.

The following table summarizes the bases used to measure certain assets and liabilities at fair value on a nonrecurring basis in 2009:

Basis of Fair Value Measurements on a Nonrecurring Basis in 2009	Significant Other Observable Inputs		Significant Other Unobservable Inputs				Total Losses
In millions	(Level 2)		(Level 3)		Total		2009
Assets at fair value:
Long-lived and other assets	$	—	$	30	$	30	$	(464	)

Goodwill	—		—		—		(7		)
Total assets at fair value	$	1,657	$	30	$	1,687	$	(471	)

As part of the restructuring plan that was approved on June 30, 2009, the Company will shut down a number of manufacturing facilities by the end of 2011. As a result, long-lived assets with a carrying value of $425 million were written down to the fair value of $26 million, resulting in an impairment charge of $399 million, which was included in the second quarter of 2009 restructuring charge (see Note C). In the fourth quarter of 2009, the Company recognized an impairment loss of $65 million (against the Performance Plastics segment) related to its investment in Equipolymers with a remaining fair value of the investment of $4 million. The long-lived assets were valued based on bids received from third parties and using discounted cash flow analysis based on assumptions that market participants would use. Key inputs included anticipated revenues, associated manufacturing costs, capital expenditures and discount, growth and tax rates.

On April 1, 2009, the Company announced the entry into a definitive agreement to sell the newly acquired stock of Morton International, Inc., the Salt business of Rohm and Haas, to K+S Aktiengesellschaft. The assets were classified as held for sale with a net carrying value of $1,657 million at September 30, 2009. The held for sale assets were valued based on the definitive agreement with K+S Aktiengesellschaft, less estimated cost to sell. The assets were sold on October 1, 2009 (see Note E).

During the fourth quarter of 2009, the Company performed its annual impairment tests for goodwill. As a result of this review, it was determined that the goodwill associated with the Dow Haltermann reporting unit was impaired. The impairment was based on a review of the Dow Haltermann reporting unit performed by management, in which discounted cash flows did not support the carrying value of the goodwill due to poor future projections for the business. As a result, an impairment loss of $7 million was recognized in the fourth quarter of 2009 against the Performance Materials segment.

NOTE N – COMMITMENTS AND CONTINGENT LIABILITIES

Litigation

Breast Implant Matters

On May 15, 1995, Dow Corning Corporation (“Dow Corning”), in which the Company is a 50 percent shareholder, voluntarily filed for protection under Chapter 11 of the Bankruptcy Code to resolve litigation related to Dow Corning’s breast implant and other silicone medical products. On June 1, 2004, Dow Corning’s Joint Plan of Reorganization (the “Joint Plan”) became effective and Dow Corning emerged from bankruptcy. The Joint Plan contains release and injunction provisions resolving all tort claims brought against various entities, including the Company, involving Dow Corning’s breast implant and other silicone medical products.

To the extent not previously resolved in state court actions, cases involving Dow Corning’s breast implant and other silicone medical products filed against the Company were transferred to the U.S. District Court for the Eastern District of Michigan (the “District Court”) for resolution in the context of the Joint Plan. On October 6, 2005, all such cases then pending in the District Court against the Company were dismissed. Should cases involving Dow Corning’s breast implant and other silicone medical products be filed against the Company in the future, they will be accorded similar treatment. It is the opinion of the Company’s management that the possibility is remote that a resolution of all future cases will have a material adverse impact on the Company’s consolidated financial statements.

As part of the Joint Plan, Dow and Corning Incorporated agreed to provide a credit facility to Dow Corning in an aggregate amount of $300 million, which was reduced to $200 million effective June 1, 2010. The Company’s share of the credit facility was originally $150 million, but was reduced to $100 million effective June 1, 2010, and is subject to the terms and conditions stated in the Joint Plan. At December 31, 2010, no draws had been taken against the credit facility.

DBCP Matters

Numerous lawsuits have been brought against the Company and other chemical companies, both inside and outside of the United States, alleging that the manufacture, distribution or use of pesticides containing dibromochloropropane (“DBCP”) has caused personal injury and property damage, including contamination of groundwater. It is the opinion of the Company’s management that the possibility is remote that the resolution of such lawsuits will have a material adverse impact on the Company’s consolidated financial statements.

Environmental Matters

Accruals for environmental matters are recorded when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated based on current law and existing technologies. At December 31, 2010, the Company had accrued obligations of $607 million for probable environmental remediation and restoration costs, including $59 million for the remediation of Superfund sites. This is management’s best estimate of the costs for remediation and restoration with respect to environmental matters for which the Company has accrued liabilities, although the ultimate cost with respect to these particular matters could range up to approximately twice that amount. Consequently, it is reasonably possible that environmental remediation and restoration costs in excess of amounts accrued could have a material adverse impact on the Company’s results of operations, financial condition and cash flows. It is the opinion of the Company’s management, however, that the possibility is remote that costs in excess of the range disclosed will have a material adverse impact on the Company’s results of operations, financial condition and cash flows. Inherent uncertainties exist in these estimates primarily due to unknown conditions, changing governmental regulations and legal standards regarding liability, and emerging remediation technologies for handling site remediation and restoration. At December 31, 2009, the Company had accrued obligations of $619 million for probable environmental remediation and restoration costs, including $80 million for the remediation of Superfund sites.

The following table summarizes the activity in the Company's accrued obligations for environmental matters for the years ended December 31, 2010 and 2009:

Accrued Obligations for Environmental Matters

The amounts charged to income on a pretax basis related to environmental remediation totaled $158 million in 2010, $269 million in 2009 and $140 million in 2008. Capital expenditures for environmental protection were $173 million in 2010, $219 million in 2009 and $193 million in 2008.

Midland Off-Site Environmental Matters

On June 12, 2003, the Michigan Department of Natural Resources and Environment ("MDNRE," formerly the Michigan Department of Environmental Quality or MDEQ) issued a Hazardous Waste Operating License (the “License”) to the Company’s Midland, Michigan manufacturing site (the “Midland site”), which included provisions requiring the Company to conduct an investigation to determine the nature and extent of off-site contamination in the City of Midland soils; the Tittabawassee River and Saginaw River sediment and floodplain soils; and the Saginaw Bay; and, if necessary, undertake remedial action.

City of Midland

Matters related to the City of Midland remain under the primary oversight of the State of Michigan (the “State”) under the License, and the Company and the State are in ongoing discussions regarding the implementation of the requirements of the License.

Tittabawassee and Saginaw Rivers, Saginaw Bay

The Company, the U.S. Environmental Protection Agency (“EPA”) and the State entered into an administrative order on consent (“AOC”), effective January 21, 2010, that requires the Company to conduct a remedial investigation, a feasibility study and a remedial design for the Tittabawassee River, the Saginaw River and the Saginaw Bay, and pay the oversight costs of the EPA and the State under the authority of the Comprehensive Environmental Response, Compensation, and Liability Act (“CERCLA”). These actions, to be conducted under the lead oversight of the EPA, will build upon the investigative work completed under the State Resource Conservation Recovery Act (“RCRA”) program from 2005 through 2009. The Tittabawassee River, beginning at the Midland Site and extending down to the first six miles of the Saginaw River, are designated as the first Operable Unit for purposes of conducting the remedial investigation, feasibility study and remedial design work. This work will be performed in a largely upriver to downriver sequence for eight geographic segments of the Tittabawassee and upper Saginaw Rivers. The remainder of the Saginaw River and the Saginaw Bay are designated as a second Operable Unit and the work associated with that unit may also be geographically segmented. The AOC does not obligate the Company to perform removal or remedial action; that action can only be required by a separate order. The Company and the EPA will be negotiating orders separate from the AOC that will obligate the Company to perform remedial actions under the scope of work of the AOC.

Alternative Dispute Resolution Process

The Company; the EPA; the U.S. Department of Justice; and the natural resource damage trustees (the Michigan Office of the Attorney General; the MDNRE; the U.S. Fish and Wildlife Service; the U.S. Bureau of Indian Affairs and the Saginaw-Chippewa tribe), have been engaged in negotiations to seek to resolve potential governmental claims against the Company related to historical off-site contamination associated with the City of Midland, the Tittabawassee and Saginaw Rivers and the Saginaw Bay. The Company and the governmental parties started meeting in the fall of 2005 and entered into a Confidentiality Agreement in December 2005. The Company continues to conduct negotiations under the Federal Alternative Dispute Resolution Act with all of the governmental parties, except the EPA which withdrew from the alternative dispute resolution process on September 12, 2007.

On September 28, 2007, the Company and the natural resource damage trustees entered into a Funding and Participation Agreement that addressed the Company’s payment of past costs incurred by the natural resource damage trustees, payment of the costs of a trustee coordinator and a process to review additional cooperative studies that the Company might agree to fund or conduct with the natural resource damage trustees. On March 18, 2008, the Company and the natural resource damage trustees entered into a Memorandum of Understanding to provide a mechanism for the Company to fund cooperative studies related to the assessment of natural resource damages. On April 7, 2008, the natural resource damage trustees released their “Natural Resource Damage Assessment Plan for the Tittabawassee River System Assessment Area.”

At December 31, 2010, the accrual for these off-site matters was $32 million (included in the total accrued obligation of $607 million). At December 31, 2009, the Company had an accrual for these off-site matters of $25 million (included in the total accrued obligation of $619 million).

Environmental Matters Summary

It is the opinion of the Company’s management that the possibility is remote that costs in excess of those disclosed will have a material adverse impact on the Company’s results of operations, financial condition and cash flows.

Asbestos-Related Matters of Union Carbide Corporation

Union Carbide Corporation (“Union Carbide”), a wholly owned subsidiary of the Company, is and has been involved in a large number of asbestos-related suits filed primarily in state courts during the past three decades. These suits principally allege personal injury resulting from exposure to asbestos-containing products and frequently seek both actual and punitive damages. The alleged claims primarily relate to products that Union Carbide sold in the past, alleged exposure to asbestos-containing products located on Union Carbide’s premises, and Union Carbide’s responsibility for asbestos suits filed against a former Union Carbide subsidiary, Amchem Products, Inc. (“Amchem”). In many cases, plaintiffs are unable to demonstrate that they have suffered any compensable loss as a result of such exposure, or that injuries incurred in fact resulted from exposure to Union Carbide’s products.

Influenced by the bankruptcy filings of numerous defendants in asbestos-related litigation and the prospects of various forms of state and national legislative reform, the rate at which plaintiffs filed asbestos-related suits against various companies, including Union Carbide and Amchem, increased in 2001, 2002 and the first half of 2003. Since then, the rate of filing has significantly abated. Union Carbide expects more asbestos-related suits to be filed against Union Carbide and Amchem in the future, and will aggressively defend or reasonably resolve, as appropriate, both pending and future claims.

Based on a study completed by Analysis, Research & Planning Corporation (“ARPC”) in January 2003, Union Carbide increased its December 31, 2002 asbestos-related liability for pending and future claims for the 15-year period ending in 2017 to $2.2 billion, excluding future defense and processing costs. Since then, Union Carbide has compared current asbestos claim and resolution activity to the results of the most recent ARPC study at each balance sheet date to determine whether the accrual continues to be appropriate. In addition, Union Carbide has requested ARPC to review Union Carbide’s historical asbestos claim and resolution activity each November since 2004 to determine the appropriateness of updating the most recent ARPC study.

In November 2008, Union Carbide requested ARPC to review Union Carbide’s historical asbestos claim and resolution activity and determine the appropriateness of updating its then most recent study completed in December 2006. In response to that request, ARPC reviewed and analyzed data through October 31, 2008. The resulting study, completed by ARPC in December 2008, stated that the undiscounted cost of resolving pending and future asbestos-related claims against Union Carbide and Amchem, excluding future defense and processing costs, through 2023 was estimated to be between $952 million and $1.2 billion. As in its earlier studies, ARPC provided estimates for a longer period of time in its December 2008 study, but also reaffirmed its prior advice that forecasts for shorter periods of time are more accurate than those for longer periods of time.

In December 2008, based on ARPC’s December 2008 study and Union Carbide’s own review of the asbestos claim and resolution activity, Union Carbide decreased its asbestos-related liability for pending and future claims to $952 million, which covered the 15-year period ending 2023, excluding future defense and processing costs. The reduction was $54 million and is shown as “Asbestos-related credits” in the consolidated statements of income. At December 31, 2008, the asbestos-related liability for pending and future claims was $934 million.

In November 2009, Union Carbide requested ARPC to review Union Carbide’s 2009 asbestos claim and resolution activity and determine the appropriateness of updating its December 2008 study. In response to that request, ARPC reviewed and analyzed data through October 31, 2009. In December 2009, ARPC stated that an update of its study would not provide a more likely estimate of future events than the estimate reflected in its study of the previous year and, therefore, the estimate in that study remained applicable. Based on Union Carbide’s own review of the asbestos claim and resolution activity and ARPC’s response, Union Carbide determined that no change to the accrual was required. At December 31, 2009, Union Carbide’s asbestos-related liability for pending and future claims was $839 million.

In November 2010, Union Carbide requested ARPC to review Union Carbide’s historical asbestos claim and resolution activity and determine the appropriateness of updating its December 2008 study. In response to that request, ARPC reviewed and analyzed data through October 31, 2010. The resulting study, completed by ARPC in December 2010, stated that the undiscounted cost of resolving pending and future asbestos-related claims against Union Carbide and Amchem, excluding future defense and processing costs, through 2025 was estimated to be between $744 million and $835 million. As in its earlier studies, ARPC provided estimates for a longer period of time in its December 2010 study, but also reaffirmed its prior advice that forecasts for shorter periods of time are more accurate than those for longer periods of time.

In December 2010, based on ARPC’s December 2010 study and Union Carbide’s own review of the asbestos claim and resolution activity, Union Carbide decreased its asbestos-related liability for pending and future claims to $744 million, which covered the 15-year period ending 2025, excluding future defense and processing costs. The reduction was $54 million and was

97

shown as “Asbestos-related credits” in the consolidated statements of income. At December 31, 2010, the asbestos-related liability for pending and future claims was $728 million.

At December 31, 2010, approximately 21 percent of the recorded liability related to pending claims and approximately 79 percent related to future claims. At December 31, 2009, approximately 23 percent of the recorded liability related to pending claims and approximately 77 percent related to future claims.

At December 31, 2002, Union Carbide increased the receivable for insurance recoveries related to its asbestos liability to $1.35 billion, substantially exhausting its asbestos product liability coverage. The insurance receivable related to the asbestos liability was determined by Union Carbide after a thorough review of applicable insurance policies and the 1985 Wellington Agreement, to which Union Carbide and many of its liability insurers are signatory parties, as well as other insurance settlements, with due consideration given to applicable deductibles, retentions and policy limits, and taking into account the solvency and historical payment experience of various insurance carriers. The Wellington Agreement and other agreements with insurers are designed to facilitate an orderly resolution and collection of Union Carbide’s insurance policies and to resolve issues that the insurance carriers may raise.

In September 2003, Union Carbide filed a comprehensive insurance coverage case, now proceeding in the Supreme Court of the State of New York, County of New York, seeking to confirm its rights to insurance for various asbestos claims and to facilitate an orderly and timely collection of insurance proceeds (the “Insurance Litigation”). The Insurance Litigation was filed against insurers that are not signatories to the Wellington Agreement and/or do not otherwise have agreements in place with Union Carbide regarding their asbestos-related insurance coverage, in order to facilitate an orderly resolution and collection of such insurance policies and to resolve issues that the insurance carriers may raise. Since the filing of the case, Union Carbide has reached settlements with several of the carriers involved in the Insurance Litigation, including settlements reached with two significant carriers in the fourth quarter of 2009. The Insurance Litigation is ongoing.

Union Carbide’s receivable for insurance recoveries related to its asbestos liability was $50 million at December 31, 2010 and $84 million at December 31, 2009. At December 31, 2010 and December 31, 2009, all of the receivable for insurance recoveries was related to insurers that are not signatories to the Wellington Agreement and/or do not otherwise have agreements in place regarding their asbestos-related insurance coverage.

In addition to the receivable for insurance recoveries related to its asbestos liability, Union Carbide had receivables for defense and resolution costs submitted to insurance carriers that have settlement agreements in place regarding their asbestos-related insurance coverage. The following table summarizes Union Carbide’s receivables related to its asbestos-related liability:

Receivables for Asbestos-Related Costs at December 31 In millions	2010		2009
Receivables for defense costs – carriers with settlement agreements	$	12	$	91
Receivables for resolution costs – carriers with settlement agreements	236		357
Receivables for insurance recoveries – carriers without settlement agreements	50		84
Total	$	298	$	532

Union Carbide expenses defense costs as incurred. The pretax impact for defense and resolution costs, net of insurance, was $73 million in 2010, $58 million in 2009 and $53 million in 2008, and was reflected in “Cost of sales.”

After a review of its insurance policies, with due consideration given to applicable deductibles, retentions and policy limits, after taking into account the solvency and historical payment experience of various insurance carriers; existing insurance settlements; and the advice of outside counsel with respect to the applicable insurance coverage law relating to the terms and conditions of its insurance policies, Union Carbide continues to believe that its recorded receivable for insurance recoveries from all insurance carriers is probable of collection.

The amounts recorded by Union Carbide for the asbestos-related liability and related insurance receivable described above were based upon current, known facts. However, future events, such as the number of new claims to be filed and/or received each year, the average cost of disposing of each such claim, coverage issues among insurers, and the continuing solvency of various insurance companies, as well as the numerous uncertainties surrounding asbestos litigation in the United States, could cause the actual costs and insurance recoveries for Union Carbide to be higher or lower than those projected or those recorded.

Because of the uncertainties described above, Union Carbide’s management cannot estimate the full range of the cost of resolving pending and future asbestos-related claims facing Union Carbide and Amchem. Union Carbide’s management believes that it is reasonably possible that the cost of disposing of Union Carbide’s asbestos-related claims, including future defense costs, could have a material adverse impact on Union Carbide’s results of operations and cash flows for a particular

98

period and on the consolidated financial position of Union Carbide.

It is the opinion of Dow’s management that it is reasonably possible that the cost of Union Carbide disposing of its asbestos-related claims, including future defense costs, could have a material adverse impact on the Company’s results of operations and cash flows for a particular period and on the consolidated financial position of the Company.

Synthetic Rubber Industry Matters

In 2003, the U.S., Canadian and European competition authorities initiated separate investigations into alleged anticompetitive behavior by certain participants in the synthetic rubber industry. Certain subsidiaries of the Company (but as to the investigation in Europe only) have responded to requests for documents and are otherwise cooperating in the investigations.

On June 10, 2005, the Company received a Statement of Objections from the European Commission (the “EC”) stating that it believed that the Company and certain subsidiaries of the Company (the “Dow Entities”), together with other participants in the synthetic rubber industry, engaged in conduct in violation of European competition laws with respect to the butadiene rubber and emulsion styrene butadiene rubber businesses. In connection therewith, on November 29, 2006, the EC issued its decision alleging infringement of Article 81 of the Treaty of Rome and imposed a fine of Euro 64.575 million (approximately $85 million at that time) on the Dow Entities; several other companies were also named and fined. As a result, the Company recognized a loss contingency of $85 million related to the fine in the fourth quarter of 2006. The Company has appealed the EC’s decision. On October 13, 2009, the Court of First Instance held a hearing on the appeal of all parties. Subsequent to the imposition of the fine, the Company and/or certain subsidiaries of the Company became named parties in various related U.S., United Kingdom and Italian civil actions. The U.S. matter was settled in March 2010 through a confidential settlement agreement, with an immaterial impact on the Company’s consolidated financial statements.

Additionally, on March 10, 2007, the Company received a Statement of Objections from the EC stating that it believed that DuPont Dow Elastomers L.L.C. (“DDE”), a former 50:50 joint venture with E.I. du Pont de Nemours and Company (“DuPont”), together with other participants in the synthetic rubber industry, engaged in conduct in violation of European competition laws with respect to the polychloroprene business. This Statement of Objections specifically names the Company, in its capacity as a former joint venture owner of DDE. On December 5, 2007, the EC announced its decision to impose a fine on the Company, among others, in the amount of Euro 48.675 million (approximately $65 million). The Company previously transferred its joint venture ownership interest in DDE to DuPont in 2005, and DDE then changed its name to DuPont Performance Elastomers L.L.C. (“DPE”). In February 2008, DuPont, DPE and the Company each filed an appeal of the December 5, 2007 decision of the EC. Based on the Company’s allocation agreement with DuPont, the Company’s share of this fine, regardless of the outcome of the appeals, will not have a material adverse impact on the Company’s consolidated financial statements.

Rohm and Haas Pension Plan Matters

In December 2005, a federal judge in the U.S. District Court for the Southern District of Indiana (the “District Court”) issued a decision granting a class of participants in the Rohm and Haas Pension Plan (the “Rohm and Haas Plan”) who had retired from Rohm and Haas, now a wholly owned subsidiary of the Company, and who elected to receive a lump sum benefit from the Rohm and Haas Plan, the right to a cost-of-living adjustment (“COLA”) as part of their retirement benefit. In August 2007, the Seventh Circuit Court of Appeals affirmed the District Court’s decision, and in March 2008, the U.S. Supreme Court denied the Rohm and Haas Plan’s petition to review the Seventh Circuit’s decision. The case was returned to the District Court for further proceedings. In October 2008 and February 2009, the District Court issued rulings that have the effect of including in the class all Rohm and Haas retirees who received a lump sum distribution without a COLA from the Rohm and Haas Plan since January 1976. These rulings are subject to appeal, and the District Court has not yet determined the amount of the COLA benefits that may be due to the class participants. The Rohm and Haas Plan and the plaintiffs entered into a settlement agreement that, in addition to settling the litigation with respect to the Rohm and Haas retirees, provides for the amendment of the complaint and amendment of the Rohm and Haas Plan to include active employees in the settlement benefits. The District Court preliminarily approved the settlement on November 24, 2009 and, following a hearing on March 12, 2010, issued a final order approving the settlement on April 12, 2010. A group of objectors to the settlement filed an appeal from the final order. In November 2010, the District Court issued an order approving class counsel’s fee award petition in an amount consistent with the terms of the settlement. The same objectors also appealed this order. Both appeals are pending.

A pension liability associated with this matter of $185 million was recognized as part of the acquisition of Rohm and Haas on April 1, 2009. The liability, which was determined in accordance with the accounting guidance for contingencies, recognized the estimated impact of the above described judicial decisions on the long-term Rohm and Haas Plan obligations owed to the applicable Rohm and Haas retirees and active employees. At December 31, 2010, the Company had a liability of $186 million ($183 million at December 31, 2009) associated with this matter.

Other Litigation Matters

In addition to breast implant, DBCP, environmental and synthetic rubber industry matters, the Company is party to a number of other claims and lawsuits arising out of the normal course of business with respect to commercial matters, including product liability, governmental regulation and other actions. Certain of these actions purport to be class actions and seek damages in very large amounts. All such claims are being contested. Dow has an active risk management program consisting of numerous insurance policies secured from many carriers at various times. These policies provide coverage that will be utilized to minimize the financial impact, if any, of the contingencies described above.

Summary

Except for the possible effect of Union Carbide’s asbestos-related liability described above, it is the opinion of the Company’s management that the possibility is remote that the aggregate of all claims and lawsuits will have a material adverse impact on the Company's consolidated financial statements.

Purchase Commitments

The Company has numerous agreements for the purchase of ethylene-related products globally. The purchase prices are determined primarily on a cost-plus basis. Total purchases under these agreements were $714 million in 2010, $784 million in 2009 and $1,502 million in 2008. The Company’s take-or-pay commitments associated with these agreements at December 31, 2010 are included in the table below.

The Company also has various commitments for take-or-pay and throughput agreements. Such commitments are at prices not in excess of current market prices. The terms of all but two of these agreements extend from one to 25 years. One agreement has terms extending to 35 years and another has terms extending to 80 years. The determinable future commitments for these agreements are included for 10 years in the following table which presents the fixed and determinable portion of obligations under the Company’s purchase commitments at December 31, 2010:

Fixed and Determinable Portion of Take-or-Pay and Throughput Obligations at December 31, 2010 In millions
2011	$	3,603
2012	3,261
2013	2,647
2014	2,055
2015	1,341
2016 and beyond	8,203
Total	$	21,110

In addition to the take-or-pay obligations at December 31, 2010, the Company had outstanding commitments which ranged from one to ten years for materials, services and other items used in the normal course of business of approximately $180 million. Such commitments were at prices not in excess of current market prices.

Guarantees

The Company provides a variety of guarantees, as described more fully in the following sections.

Guarantees

Guarantees arise during the ordinary course of business from relationships with customers and nonconsolidated affiliates when the Company undertakes an obligation to guarantee the performance of others (via delivery of cash or other assets) if specified triggering events occur. With guarantees, such as commercial or financial contracts, non-performance by the guaranteed party triggers the obligation of the Company to make payments to the beneficiary of the guarantee. The majority of the Company’s guarantees relate to debt of nonconsolidated affiliates, which have expiration dates ranging from less than one year to ten years, and trade financing transactions in Latin America and Asia Pacific, which typically expire within one year of their inception. The Company’s current expectation is that future payment or performance related to the non-performance of others is considered unlikely.

Residual Value Guarantees

The Company provides guarantees related to leased assets specifying the residual value that will be available to the lessor at lease termination through sale of the assets to the lessee or third parties.

The following tables provide a summary of the final expiration, maximum future payments and recorded liability reflected in the consolidated balance sheets for each type of guarantee:

Asset Retirement Obligations

Dow has 188 manufacturing sites in 35 countries. Most of these sites contain numerous individual manufacturing operations, particularly at the Company’s larger sites. Asset retirement obligations are recorded as incurred and reasonably estimable, including obligations for which the timing and/or method of settlement are conditional on a future event that may or may not be within the control of the Company. The retirement of assets may involve such efforts as remediation and treatment of asbestos, contractually required demolition, and other related activities, depending on the nature and location of the assets, and retirement obligations are typically realized only upon demolition of those facilities. In identifying asset retirement obligations, the Company considers identification of legally enforceable obligations, changes in existing law, estimates of potential settlement dates and the calculation of an appropriate discount rate to be used in calculating the fair value of the obligations. Dow has a well-established global process to identify, approve and track the demolition of retired or to-be-retired facilities; and no assets are retired from service until this process has been followed. Dow typically forecasts demolition projects based on the usefulness of the assets; environmental, health and safety concerns; and other similar considerations. Under this process, as demolition projects are identified and approved, reasonable estimates are determined for the time frames during which any related asset retirement obligations are expected to be settled. For those assets where a range of potential settlement dates may be reasonably estimated, obligations are recorded. Dow routinely reviews all changes to items under consideration for demolition to determine if an adjustment to the value of the asset retirement obligation is required.

The Company has recognized asset retirement obligations for the following activities: demolition and remediation activities at manufacturing sites in the United States, Canada, Brazil, Chile, China and Europe; and capping activities at landfill sites in the United States, Canada, Brazil and Europe. The Company has also recognized conditional asset retirement obligations related to asbestos encapsulation as a result of planned demolition and remediation activities at manufacturing and administrative sites in the United States, Canada, Brazil, Chile, China and Europe. The aggregate carrying amount of conditional asset retirement obligations recognized by the Company (included in the asset retirement obligations balance) was $40 million at December 31, 2010 ($41 million at 2009).

The following table shows changes in the aggregate carrying amount of the Company’s asset retirement obligations:

101

The discount rate used to calculate the Company’s asset retirement obligations at December 31, 2010 was 1.78 percent (2.45 percent at December 31, 2009). These obligations are included in the consolidated balance sheets as “Other noncurrent obligations.”

The Company has not recognized conditional asset retirement obligations for which a fair value cannot be reasonably estimated in its consolidated financial statements. Assets that have not been submitted/reviewed for potential demolition activities are considered to have continued usefulness and are generally still operating normally. Therefore, without a plan to demolish the assets or the expectation of a plan, such as shortening the useful life of assets for depreciation purposes in accordance with the accounting guidance related to property, plant and equipment, the Company is unable to reasonably forecast a time frame to use for present value calculations. As such, the Company has not recognized obligations for individual plants/buildings at its manufacturing sites where estimates of potential settlement dates cannot be reasonably made. In addition, the Company has not recognized conditional asset retirement obligations for the capping of its approximately 60 underground storage wells and 130 underground brine mining and other wells at Dow-owned sites when there are no plans or expectations of plans to exit the sites. It is the opinion of the Company’s management that the possibility is remote that such conditional asset retirement obligations, when estimable, will have a material adverse impact on the Company’s consolidated financial statements based on current costs.

NOTE O – TRANSFERS OF FINANCIAL ASSETS

On January 1, 2010, the Company adopted ASU 2009-16, “Transfers and Servicing (Topic 860): Accounting for Transfers of Financial Assets.” This ASU is intended to improve the information provided in financial statements concerning transfers of financial assets, including the effects of transfers on financial position, financial performance and cash flows, and any continuing involvement of the transferor with the transferred financial assets. The Company evaluated the impact of adopting the guidance and the terms and conditions in place at January 1, 2010 and determined that certain sales of accounts receivable would be classified as secured borrowings. Under the Company’s sale of accounts receivable arrangements, $915 million was outstanding at January 1, 2010. The maximum amount of receivables available for participation in these programs was $1,939 million at January 1, 2010.

In January 2010, the Company terminated the North American arrangement and replaced it with a new arrangement that qualified for treatment as a sale under ASU 2009-16. The arrangement related to $294 million of the $915 million outstanding at January 1, 2010 and $1,100 million of the $1,939 million maximum participation.

In June 2010, the Company terminated the European arrangement and replaced it with a new arrangement that qualified for treatment as a sale under ASU 2009-16. The arrangement related to $584 million of the $915 million outstanding at January 1, 2010 and $721 million of the $1,939 million maximum participation.

Sale of Trade Accounts Receivable in North America

In January 2010, the Company terminated its previous facilities used in North America for the transfers of trade accounts receivable by entering into an agreement to repurchase the outstanding receivables for $264 million and replacing it with a new arrangement. During the year ended December 31, 2010, under the new arrangement, the Company sold the trade accounts receivable of select North America entities on a revolving basis to certain multi-seller commercial paper conduit entities. The Company maintains servicing responsibilities and the related costs are insignificant. The proceeds received are comprised of cash and interests in specified assets (the receivables sold by the Company) of the conduits that entitle the Company to the residual cash flows of such specified assets in the conduits after the commercial paper has been repaid. Neither the conduits nor the investors in those entities have recourse to other assets of the Company in the event of nonpayment by the debtors.

During the year ended December 31, 2010, the Company recognized a loss of $19 million on the sale of these receivables, which is classified as “Interest expense and amortization of debt discount” in the consolidated statements of income. The Company classifies its interests in the conduits as “Accounts and notes receivable – Other” on the consolidated balance sheets and those interests are carried at fair value. Fair value of the interests is determined by calculating the expected amount of cash to be received and is based on unobservable inputs (a Level 3 measurement). The key input in the valuation is percentage of anticipated credit losses, which was 1.42 percent, in the portfolio of receivables sold that have not yet been collected. Given the short-term nature of the underlying receivables, discount rates and prepayments are not factors in determining the fair value of the interests. At December 31, 2010, the carrying value of the interests held was $1,110 million, which is the Company’s maximum exposure to loss related to the receivables sold.

102

The sensitivity of the fair value of the interests held to hypothetical adverse changes in the anticipated credit losses are as follows (amounts shown are the corresponding hypothetical decreases in the carrying value of the interests):

Delinquencies on the sold receivables that were still outstanding at December 31, 2010 were $127 million. Trade accounts receivable outstanding and derecognized from the Company’s consolidated balance sheets at December 31, 2010 were $1,930 million. Credit losses, net of any recoveries, on receivables sold during the year ended December 31, 2010 were $2 million. During 2010, the Company repurchased $13 million of previously sold receivables related to a divestiture.

Sale of TradeAccounts Receivable in Europe

In June 2010, the Company terminated its previous facility used in Europe for the transfers of trade accounts receivable by entering into an agreement to repurchase the outstanding receivables for $11 million and replacing it with a new arrangement. Since June 2010, under the new arrangement, the Company sold qualifying trade accounts receivable of select European entities on a revolving basis to certain multi-seller commercial paper conduit entities. The Company maintains servicing responsibilities and the related costs are insignificant. The proceeds received are comprised of cash and interests in specified assets (the receivables sold by the Company) of the conduits that entitle the Company to the residual cash flows of such specified assets in the conduits after the commercial paper has been repaid. Neither the conduits nor the investors in those entities have recourse to other assets of the Company in the event of nonpayment by the debtors.

During the period from the June 2010 inception of the new arrangement through December 31, 2010, the Company recognized a loss of $7 million on the sale of these receivables, which is classified as “Interest expense and amortization of debt discount” in the consolidated statements of income. The Company classifies its interests in the conduits as “Accounts and notes receivable – Other” on the consolidated balance sheets and those interests are carried at fair value. Fair value of the interests is determined by calculating the expected amount of cash to be received and is based on unobservable inputs (a Level 3 measurement). The key input in the valuation is percentage of anticipated credit losses, which was zero, in the portfolio of receivables sold that have not yet been collected. Given the short-term nature of the underlying receivables, discount rates and prepayments are not factors in determining the fair value of the interests. At December 31, 2010, the carrying value of the interests held was $157 million, which is the Company’s maximum exposure to loss related to the receivables sold.

Following is an analysis of certain cash flows between the Company and the European conduits:

Delinquencies on the sold receivables still outstanding at December 31, 2010 were $42 million. Trade accounts receivable outstanding and derecognized from the Company’s consolidated balance sheets at December 31, 2010 were $405 million. There were no credit losses on receivables sold since June 2010.

103

Sale of Trade Accounts Receivable in Asia Pacific

During the year ended December 31, 2010, the Company sold participating interests in trade accounts receivable of select Asia Pacific entities for which the Company received cash. The Company maintains servicing responsibilities for the participating interests sold and the related costs are insignificant. The third-party holders of the participating interests do not have recourse to the Company’s assets in the event of nonpayment by the debtors.

During the year ended December 31, 2010, the Company recognized a loss of less than $1 million on the sale of the participating interests in the receivables, which is classified as “Interest expense and amortization of debt discount” in the consolidated statements of income.

Following is an analysis of certain cash flows between the Company and the third-party holders of the participating interests:

Cash Proceeds
In millions	2010
Sale of participating interests	$	218
Collections reinvested in revolving receivables	$	195

On November 4, 2010, the Company issued $2.5 billion of debt securities in a public offering. The offering included $750 million aggregate principal amount of 2.50 percent notes due 2016 and $1.75 billion aggregate principal amount of 4.25 percent notes due 2020.

On March 9, 2009, the Company borrowed $3 billion under its Five Year Competitive Advance and Revolving Credit Facility Agreement, dated April 24, 2006 (“Agreement”); $1.6 billion of the funds were repaid on May 15, 2009; $0.5 billion of the funds were repaid on June 30, 2009; and the remaining $0.9 billion of the funds were repaid on December 30, 2009. The funds were due in April 2011 and bore interest at a variable London Interbank Offered Rate (“LIBOR”)-plus rate or Base Rate as defined in the Agreement. The Company used the funds to finance day-to-day operations, to repay indebtedness maturing in the ordinary course of business and for other general corporate purposes. In 2010, the Company replaced the Agreement with a new $3 billion Three Year Competitive Advance and Revolving Credit Facility Agreement dated June 4, 2010 (“Revolving Credit Facility”) with various U.S. and foreign banks. The Revolving Credit Facility has a maturity date in June 2013 and provides for interest at a LIBOR-plus rate or Base Rate as defined in the Revolving Credit Facility. At December 31, 2010, the full $3 billion credit facility was available to the Company.

Debt financing for the acquisition of Rohm and Haas was provided by a $9,226 million draw on a Term Loan Agreement dated September 8, 2008 (“Term Loan”) on April 1, 2009. The original maturity date of the Term Loan was April 1, 2010, provided however, that the maturity date could have been extended for an additional year at the option of the Company, for a maximum outstanding balance of $8.0 billion. Prepaid up-front debt issuance costs of $304 million were paid. Amortization of the prepaid costs was accelerated concurrent with the repayment of the Term Loan. The Term Loan was repaid through a combination of proceeds obtained through asset sales and the issuance of debt and equity securities. At December 31, 2009, the Term Loan balance was zero and the Term Loan was terminated.

105

On May 7, 2009, the Company issued $6 billion of debt securities in a public offering. The offering included $1.75 billion aggregate principal amount of 7.6 percent notes due 2014; $3.25 billion aggregate principal amount of 8.55 percent notes due 2019; and $1 billion aggregate principal amount of 9.4 percent notes due 2039. Aggregate principal amount of $1.35 billion of the 8.55 percent notes due 2019 were offered by accounts and funds managed by Paulson & Co. Inc. and trusts created by members of the Haas family. These investors received notes from the Company in payment for 1.3 million shares of the Company’s Perpetual Preferred Stock, Series B, at par plus accrued dividends (see Note W for further information). The Company used the net proceeds received from this offering for refinancing, renewals, replacements and refunding of outstanding indebtedness, including repayment of a portion of the Term Loan.

On August 4, 2009, the Company issued $2.75 billion of debt securities in a public offering. The offering included $1.25 billion aggregate principal amount of 4.85 percent notes due 2012; $1.25 billion aggregate principal amount of 5.90 percent notes due 2015; and $0.25 billion aggregate principal amount of LIBOR-plus based floating rate notes due 2011. The Company used the net proceeds received from this offering for refinancing, renewals, replacements and refunding of outstanding indebtedness, including repayment of a portion of the Term Loan.

The fair value of debt assumed from Rohm and Haas on April 1, 2009 of $2,576 million is reflected in the long-term debt table above. On August 21, 2009, the Company executed a buy-back of Euro 175 million of private placement debt acquired from Rohm and Haas and recognized a $56 million pretax loss on this early extinguishment, included in “Sundry income – net.” On September 8, 2010, the Company concluded a tender offer for any and all of $145 million of debentures acquired from Rohm and Haas, due June 2020. As a result of the tender offer, the Company redeemed $123 million of the debentures and recognized a $46 million pretax loss on this early extinguishment, included in “Sundry income – net.”

On September 28, 2009, Calvin Capital LLC, a wholly owned subsidiary of the Company, repaid a $674 million note payable, which was issued in September 2008.

The Company’s outstanding debt of $22.4 billion has been issued under indentures which contain, among other provisions, covenants with which the Company must comply while the underlying notes are outstanding. Such covenants include obligations to not allow liens on principal U.S. manufacturing facilities, enter into sale and lease-back transactions with respect to principal U.S. manufacturing facilities, or merge or consolidate with any other corporation, or sell or convey all or substantially all of the Company’s assets. The outstanding debt also contains customary default provisions. Failure of the Company to comply with any of these covenants could result in a default under the applicable indenture, which would allow the note holders to accelerate the due date of the outstanding principal and accrued interest on the subject notes.

The Company’s primary credit agreements contain covenant and default provisions in addition to the covenants set forth above with respect to the Company’s debt. Significant other covenants and default provisions related to these agreements include:

(a) the obligation to maintain the ratio of the Company’s consolidated indebtedness to consolidated capitalization at no greater than 0.65 to 1.00 at any time the aggregate outstanding amount of loans under the Revolving Credit Facility exceeds $500 million,

(b) a default if the Company or an applicable subsidiary fails to make any payment on indebtedness of $50 million or more when due, or any other default under the applicable agreement permits the acceleration of $200 million or more of principal, or results in the acceleration of $100 million or more of principal, and

(c) a default if the Company or any applicable subsidiary fails to discharge or stay within 30 days after the entry of a final judgment of more than $200 million.

Failure of the Company to comply with any of the covenants or default provisions could result in a default under the applicable credit agreement which would allow the lenders to not fund future loan requests and to accelerate the due date of the outstanding principal and accrued interest on any outstanding loans.

At December 31, 2010, management believes the Company was in compliance with all of the covenants and default provisions referred to above.

NOTE Q – PENSION PLANS AND OTHER POSTRETIREMENT BENEFITS

Acquisition of Rohm and Haas

With the April 1, 2009 acquisition of Rohm and Haas (see Note D), the Company assumed sponsorship of qualified and non-qualified pension and other postretirement benefit plans that provide defined benefits to U.S. and non-U.S. employees. As a result, the Company acquired the following plan assets and obligations from Rohm and Haas:

Plan Assets and Obligations Acquired from Rohm and Haas  on April 1, 2009 (1)
In millions	Defined Benefit Pension Plans		Other Postretirement Benefits
Fair value of plan assets	$	1,439	$	18
Projected benefit obligation	$	2,168	$	338

(1) Does not include plan assets and obligations of Morton that were sold to K+S on October 1, 2009; see Note E.

Pension Plans

The Company has defined benefit pension plans that cover employees in the United States and a number of other countries. The U.S. qualified plan covering the parent company is the largest plan. Benefits are based on length of service and the employee’s three highest consecutive years of compensation. Employees hired after January 1, 2008 earn benefits that are based on a set percentage of annual pay, plus interest.

The Company’s funding policy is to contribute to the plans when pension laws and/or economics either require or encourage funding. In 2010, Dow contributed $708 million to its pension plans, including contributions to fund benefit payments for its non-qualified supplemental plans. Dow expects to contribute approximately $700 million to its pension plans in 2011.

The weighted-average assumptions used to determine pension plan obligations and net periodic benefit costs for the plans are provided in the two tables below:

Weighted-Average Assumptions  for All Pension Plans	Benefit Obligations at December 31				Net Periodic Costs for the Year
	2010		2009		2010		2009
Discount rate	5.38	%	5.71	%	5.71	%	6.53	%
Rate of increase in future compensation levels	4.13	%	4.14	%	4.17	%	4.01	%
Expected long-term rate of return on plan assets	—		—		7.74	%	8.03	%

Weighted-Average Assumptions  for U.S. Pension Plans	Benefit Obligations at December 31				Net Periodic Costs for the Year
	2010		2009		2010		2009
Discount rate	5.51	%	5.97	%	5.97	%	6.82	%
Rate of increase in future compensation levels	4.50	%	4.50	%	4.50	%	4.31	%
Expected long-term rate of return on plan assets	—		—		8.16	%	8.46	%

The Company determines the expected long-term rate of return on plan assets by performing a detailed analysis of key economic and market factors driving historical returns for each asset class and formulating a projected return based on factors in the current environment. Factors considered include, but are not limited to, inflation, real economic growth, interest rate yield, interest rate spreads, and other valuation measures and market metrics. The expected long-term rate of return for each asset class is then weighted based on the strategic asset allocation approved by the governing body for each plan. The Company’s historical experience with the pension fund asset performance is also considered. A similar process is followed in determining the expected long-term rate of return for assets held in the Company’s other postretirement benefit plan trusts. The discount rates utilized to measure the pension and other postretirement obligations of the U.S. qualified plans are based on the yield on high-quality fixed income investments at the measurement date. Future expected actuarially determined cash flows of Dow’s major U.S. plans are matched against the Towers Watson RATE:Link yield curve (based on 60th to 90th percentile bond yields) to arrive at a single discount rate for each plan.

107

The accumulated benefit obligation for all defined benefit pension plans was $20.1 billion at December 31, 2010 and $18.9 billion at December 31, 2009.

Pension Plans with Accumulated Benefit Obligations in Excess  of Plan Assets at December 31

In addition to the U.S. qualified defined benefit pension plan, U.S. employees may participate in defined contribution plans (Employee Savings Plans or 401(k) plans) by contributing a portion of their compensation, which is partially matched by the Company. Defined contribution plans also cover employees in some subsidiaries in other countries, including Australia, Brazil, Canada, Italy, Spain and the United Kingdom. Expense recognized for all defined contribution plans was $184 million in 2010, $156 million in 2009 and $49 million in 2008.

Other Postretirement Benefits

The Company provides certain health care and life insurance benefits to retired employees. The Company’s plans outside of the United States are not significant; therefore, this discussion relates to the U.S. plans only. The plans provide health care benefits, including hospital, physicians’ services, drug and major medical expense coverage, and life insurance benefits. In general, for employees hired before January 1, 1993, the plans provide benefits supplemental to Medicare when retirees are eligible for these benefits. The Company and the retiree share the cost of these benefits, with the Company portion increasing as the retiree has increased years of credited service, although there is a cap on the Company portion. The Company has the ability to change these benefits at any time. Employees hired after January 1, 2008 are not covered under the plans.

The Company funds most of the cost of these health care and life insurance benefits as incurred. In 2010, Dow did not make any contributions to its other postretirement benefit plan trusts. Likewise, Dow does not expect to contribute assets to its other postretirement benefits plan trusts in 2011.

The weighted-average assumptions used to determine other postretirement benefit obligations and net periodic benefit costs for the U.S. plans are provided below:

U.S. Plan Assumptions for Other  Postretirement Benefits	Benefit Obligations at December 31				Net Periodic Costs for the Year
	2010		2009		2010		2009
Discount rate	5.15	%	5.69	%	5.69	%	7.11	%
Expected long-term rate of return on plan assets	—		—		4.35	%	5.15	%
Initial health care cost trend rate	8.70	%	9.13	%	9.13	%	9.71	%
Ultimate health care cost trend rate	5.00	%	5.00	%	5.00	%	6.00	%
Year ultimate trend rate to be reached	2019		2019		2019		2018

Increasing the assumed medical cost trend rate by one percentage point in each year would increase the accumulated postretirement benefit obligation at December 31, 2010 by less than $1 million and decrease the net periodic postretirement benefit cost for the year by $1 million. Decreasing the assumed medical cost trend rate by one percentage point in each year would increase the accumulated postretirement benefit obligation at December 31, 2010 by $23 million and the net periodic postretirement benefit cost for the year by $1 million.

Plan Assets

Plan assets consist mainly of equity and fixed income securities of U.S. and foreign issuers, and may include alternative investments such as real estate, private equity and absolute return strategies. At December 31, 2010, plan assets totaled $15.9 billion and included Company common stock with a value of $13 million (less than 1 percent of total plan assets). At December 31, 2009, plan assets totaled $14.6 billion and included Company common stock with a value of $11 million (less than 1 percent of total plan assets).

Investment Strategy and Risk Management for Plan Assets

The Company’s investment strategy for the plan assets is to manage the assets in relation to the liability in order to pay retirement benefits to plan participants while minimizing cash contributions from the Company over the life of the plans. This is accomplished by identifying and managing the exposure to various market risks, diversifying investments across various asset classes and earning an acceptable long-term rate of return consistent with an acceptable amount of risk, while considering the liquidity needs of the plans.

The plans are permitted to use derivative instruments for investment purposes, as well as for hedging the underlying asset and liability exposure and rebalancing the asset allocation. The plans use value at risk, stress testing, scenario analysis and Monte Carlo simulation to monitor and manage both risk in the portfolios and surplus risk.

Equity securities primarily include investments in large- and small-cap companies located in both developed and emerging markets around the world. Fixed income securities are primarily U.S. dollar based and include investment grade corporate bonds of companies diversified across industries, U.S. treasuries, non-U.S. developed market securities and U.S. agency mortgage-backed securities. Alternative investments primarily include investments in real estate, private equity limited partnerships and absolute return strategies. Other significant investment types include various insurance contracts; and interest rate, equity, commodity and foreign exchange derivative investments and hedges.

Strategic Weighted-Average Target Allocation of Plan Assets for All Significant Plans
Asset Category	Target Allocation
Equity securities	45	%
Fixed Income securities	35	%
Alternative investments	15	%
Other investments	5	%
Total	100	%

Concentration of Risk

The Company mitigates the credit risk of investments by establishing guidelines with investment managers that limit investment in any single issue or issuer to an amount that is not material to the portfolio being managed. These guidelines are monitored for compliance both by the Company and external managers. Credit risk related to derivative activity is mitigated by utilizing multiple counterparties and through collateral support agreements.

The JP Morgan Federal Agency money market fund is utilized as the sweep vehicle for the two largest U.S. plans, which from time to time can represent a significant investment. For one U.S. plan, approximately half of the liability is covered by a participating group annuity issued by Prudential Insurance Company.

For pension or other postretirement benefit plan assets classified as Level 1 measurements (measured using quoted prices in active markets), total fair value is either the price of the most recent trade at the time of the market close or the official close price, as defined by the exchange on which the asset is most actively traded on the last trading day of the period, multiplied by the number of units held without consideration of transaction costs.

For pension or other postretirement benefit plan assets classified as Level 2 measurements, where the security is frequently traded in less active markets, fair value is based on the closing price at the end of the period; where the security is less frequently traded, fair value is based on the price a dealer would pay for the security or similar securities, adjusted for any terms specific to that asset or liability. Market inputs are obtained from well-established and recognized vendors of market data and subjected to tolerance/quality checks. For derivative assets and liabilities, standard industry models are used to calculate the fair value of the various financial instruments based on significant observable market inputs, such as foreign exchange rates, commodity prices, swap rates, interest rates and implied volatilities obtained from various market sources.

Some pension or other postretirement benefit plan assets are held in funds where a net asset value is calculated based on the fair value of the underlying assets and the number of shares owned. The classification of the fund (Level 1, 2 or 3 measurements) is determined based on the classification of the significant holdings within the fund. For all other pension or other postretirement benefit plan assets for which observable inputs are used, fair value is derived through the use of fair value models, such as a discounted cash flow model or other standard pricing models.

113

For pension or other postretirement benefit plan assets classified as Level 3 measurements, total fair value is based on significant unobservable inputs including assumptions where there is little, if any, market activity for the investment. Investment managers or fund managers provide valuations of the investment on a monthly or quarterly basis. These valuations are reviewed for reasonableness based on applicable sector, benchmark and company performance. Adjustments to valuations are made where appropriate. Where available, audited financial statements are obtained and reviewed for the investments as support for the manager’s investment valuation.

The following tables summarize the changes in fair value of Level 3 pension plan assets for the years ended December 31, 2009 and 2010:

NOTE R – LEASED PROPERTY

Leased Property

The Company routinely leases premises for use as sales and administrative offices, warehouses and tanks for product storage, motor vehicles, railcars, computers, office machines, and equipment under operating leases. In addition, the Company leases aircraft in the United States. At the termination of the leases, the Company has the option to purchase certain leased equipment and buildings based on a fair market value determination. In 2009, the Company purchased a previously leased ethylene plant in Canada for $713 million.

Rental expenses under operating leases, net of sublease rental income, were $404 million in 2010, $459 million in 2009 and $439 million in 2008. Future minimum rental payments under operating leases with remaining noncancelable terms in excess of one year are as follows:

NOTE S – VARIABLE INTEREST ENTITIES

On January 1, 2010, the Company adopted ASU 2009-17, “Consolidations (Topic 810): Improvements to Financial Reporting by Enterprises Involved with Variable Interest Entities.” ASU 2009-17 amends the consolidation guidance applicable to variable interest entities (“VIEs”) and requires additional disclosures concerning an enterprise’s continuing involvement with VIEs. The Company evaluated the impact of this guidance and determined that the adoption resulted in the January 1, 2010 consolidation of two additional joint ventures, an owner trust and an entity that is used to monetize accounts receivable. The Company elected prospective application of this guidance at adoption.

The following table summarizes the carrying amount of the assets and liabilities of the two additional joint ventures and the owner trust entity included in the Company’s consolidated balance sheet at January 1, 2010.

Assets and Liabilities of Newly Consolidated VIEs Included in the  Consolidated Balance Sheet In millions	Jan 1, 2010
Current assets	$	37
Property	209
Other noncurrent assets	3
Total assets	$	249
Current liabilities	$	76
Long-term debt	346
Total liabilities	$	422

The carrying amounts of assets and liabilities pertaining to the entity used to monetize accounts receivable, included in the Company’s consolidated balance sheet at January 1, 2010, were current assets of $817 million (including $436 million of restricted cash) and current liabilities of $589 million.

Consolidated Variable Interest Entities

The Company holds a variable interest in five joint ventures for which the Company is the primary beneficiary. Three of the joint ventures are development stage enterprises, which will produce propylene oxide and hydrogen peroxide and provide terminal services in Thailand. The Company’s variable interest in these joint ventures relates to cost-plus arrangements between the joint venture and the Company, involving the majority of the output on take-or-pay terms and ensuring a guaranteed return

115

to the joint ventures.

Another joint venture will construct, own and operate a membrane chlor-alkali facility to be located at the Company’s Freeport, Texas integrated manufacturing complex. The Company’s variable interests in this joint venture relate to equity options between the partners and a cost-plus off-take arrangement between the joint venture and the Company, involving proportional purchase commitments on take-or-pay terms and ensuring a guaranteed return to the joint venture. The Company will provide the joint venture with operation and maintenance services, utilities and raw materials; market the joint venture’s co-products; and toll convert the other partner’s proportional purchase commitments into ethylene dichloride. The joint venture is expected to begin operations in mid-2013.

The fifth joint venture was acquired through the acquisition of Rohm and Haas on April 1, 2009. This joint venture manufactures products in Japan for the semiconductor industry. Each joint venture partner holds several equivalent variable interests, with the exception of a royalty agreement held exclusively between the joint venture and the Company. In addition, the entire output of the joint venture is sold to the Company for resale to third-party customers.

The Company also holds a variable interest in an owner trust, for which the Company is the primary beneficiary. The owner trust leases an ethylene facility in The Netherlands to the Company, whereby substantially all of the rights and obligations of ownership are transferred to the Company. The Company’s variable interest in the owner trust relates to a residual value guarantee provided to the owner trust. Upon expiration of the lease, which matures in 2014, the Company may purchase the facility for an amount based on a fair market value determination. At December 31, 2010, the Company had provided to the owner trust a residual value guarantee of $363 million, which represents the Company’s maximum exposure to loss under the lease.

As the primary beneficiary of these VIEs, the entities’ assets, liabilities and results of operations are included in the Company’s consolidated financial statements. The other equity holders’ interests are reflected in “Net income attributable to noncontrolling interests” in the consolidated statements of income and “Noncontrolling interests” in the consolidated balance sheets. The following table summarizes the carrying amounts of the entities’ assets and liabilities included in the Company’s consolidated balance sheets at December 31, 2010 and December 31, 2009:

Assets and Liabilities of Consolidated VIEs  In millions	Dec 31, 2010		Dec 31, 2009
Current assets (restricted 2010: $228)	$	228	$	102

The Company holds a variable interest in an entity created in June 2010 to monetize accounts receivable of select European entities. The Company is the primary beneficiary of this entity as a result of holding subordinated notes while maintaining servicing responsibilities for the accounts receivable. The carrying amounts of assets and liabilities pertaining to this entity, included in the Company’s consolidated balance sheet at December 31, 2010, were current assets of $158 million (zero restricted) and current liabilities of $1 million ($1 million nonrecourse). Prior to the creation of this entity, the Company held a variable interest in another entity that was also used to monetize accounts receivable originated by several European subsidiaries. That arrangement was terminated in June 2010. No gain or loss was recognized as a result of terminating the arrangement.

Amounts presented in the consolidated balance sheets and the table above as restricted assets or nonrecourse obligations relating to consolidated VIEs at December 31, 2010 are adjusted for intercompany eliminations, parental guarantees and residual value guarantees.

In September 2001, Hobbes Capital S.A. (“Hobbes”), a former consolidated foreign subsidiary of the Company, issued $500 million of preferred securities in the form of equity certificates. The certificates provided a floating rate of return (which could be reinvested) based on LIBOR. Under the accounting guidance for consolidation, Hobbes was a VIE and the Company was the primary beneficiary. During the third quarter of 2008, the other partner of Hobbes redeemed its $674 million ownership in Hobbes. The minority ownership was redeemed in a non-cash transaction in exchange for a three-year note payable with a

floating rate based on LIBOR, which was repaid in September 2009. Prior to redemption, the preferred return was included in “Net income attributable to noncontrolling interests” in the consolidated statements of income.

Nonconsolidated Variable Interest Entity

The Company holds a variable interest in a joint venture accounted for under the equity method of accounting, acquired through the acquisition of Rohm and Haas on April 1, 2009. The joint venture manufactures crude acrylic acid in the United States and Germany on behalf of the Company and the other joint venture partner. The variable interest relates to a cost-plus arrangement between the joint venture and each joint venture partner. The Company is not the primary beneficiary, as a majority of the joint venture’s output is sold to the other joint venture partner, and therefore the entity is not consolidated. At December 31, 2010, the Company’s investment in the joint venture was $144 million, classified as “Investment in nonconsolidated affiliates” in the consolidated balance sheets, representing the Company’s maximum exposure to loss.

NOTE T – STOCK-BASED COMPENSATION

The Company grants stock-based compensation to employees and non-employee directors in the form of the Employees’ Stock Purchase Plan (“ESPP”) and stock option plans, which include deferred and restricted stock. Information regarding these plans is provided below.

Accounting for Stock-Based Compensation

The Company grants stock-based compensation awards that vest over a specified period or upon employees meeting certain performance and/or retirement eligibility criteria. The fair value of equity instruments issued to employees is measured on the grant date. The fair value of liability instruments issued to employees (specifically, performance deferred stock awards, which are granted to executive employees subject to stock ownership requirements, that provide the recipient the option to elect to receive a cash payment equal to the value of the stock award on the date of delivery) is measured at the end of each quarter. The fair value of equity and liability instruments is expensed over the vesting period or, in the case of retirement, from the grant date to the date on which retirement eligibility provisions have been met and additional service is no longer required.

The Company uses a lattice-based option valuation model to estimate the fair value of stock options, the Black-Scholes option valuation model for subscriptions to purchase shares under the ESPP and Monte Carlo simulation for the market portion of performance deferred stock awards. The weighted-average assumptions used to calculate total stock-based compensation are included in the following table:

	2010		2009		2008
Dividend yield	2.5	%	3.8	%	4.4	%
Expected volatility	47.35	%	43.78	%	29.57	%
Risk-free interest rate	1.28	%	1.61	%	3.42	%
Expected life of stock options granted during period (years)	6.5		6.25		6
Life of Employees’ Stock Purchase Plan (months)	5		9		6.5

The dividend yield assumption for 2010 was based on a 30 percent / 70 percent blend of the Company’s current declared dividend as a percentage of the stock price on the grant date and a 10-year dividend yield average. The dividend yield assumption for 2009 was based on a 10-year dividend yield average. The dividend yield assumption for 2008 was based on the Company’s current declared dividend as a percentage of the stock price on the grant date. The expected volatility assumption for 2009 was based entirely on historical daily volatility, while the expected volatility assumption for 2010 and 2008 was based on an equal weighting of the historical daily volatility and current implied volatility from exchange-traded options for the contractual term of the options. The risk-free interest rate for all years was based on the weighted-average of U.S. Treasury strip rates over the contractual term of the options. The expected life of stock options granted was based on an analysis of historical exercise patterns.

Employees’ Stock Purchase Plan

On February 13, 2003, the Board of Directors authorized a 10-year ESPP, which was approved by stockholders at the Company’s annual meeting on May 8, 2003. Under the 2010 annual offering, most employees were eligible to purchase shares of common stock of the Company valued at up to 10 percent of their annual base earnings. The value is determined using the plan price multiplied by the number of shares subscribed to by the employee. The plan price of the stock is set each year at no less than 85 percent of market price.

Stock Option Plans

Under the 1988 Award and Option Plan (the “1988 Plan”), a plan approved by stockholders, the Company may grant options or shares of common stock to its employees subject to certain annual and individual limits. The terms of the grants are fixed at the grant date. At December 31, 2010, there were 22,612,549 shares available for grant under this plan.

Under the 1994 Non-Employee Directors’ Stock Plan, the Company was previously allowed to grant up to 300,000 options to non-employee directors; however, no additional grants will be made under this plan. At December 31, 2010, there were 34,650 options outstanding under this plan.

Under the 1998 Non-Employee Directors’ Stock Plan, the Company was previously allowed to grant up to 600,000 options to non-employee directors; however, no additional grants will be made under this plan. At December 31, 2010, there were 85,000 options outstanding under this plan.

The exercise price of each stock option equals the market price of the Company’s stock on the date of grant. Options vest from one to three years, and have a maximum term of 10 years.

Total unrecognized compensation cost related to deferred stock awards of $82 million at December 31, 2010 is expected to be recognized over a weighted-average period of 0.88 years. At December 31, 2010, approximately 178,288 deferred shares with a grant date weighted-average fair value per share of $29.88 had previously vested, but were not issued. These shares are scheduled to be issued to employees within one to four years or upon retirement.

Also under the 1988 Plan, the Company has granted performance deferred stock awards that vest when the Company attains specified performance targets over a predetermined period, generally one to three years. Compensation expense related to performance deferred stock awards is recognized over the lesser of the service or performance period. Changes in the fair value of liability instruments are recognized as compensation expense each quarter. The following table shows the performance deferred stock awards granted:

Performance Deferred Stock Awards		Target Shares Granted (1)	Grant Date Fair Value (2)

At December 31, 2010, approximately 0.9 million performance deferred shares with a grant date weighted-average fair value of $38.38 per share were vested, but not issued. These shares are scheduled to be issued in April 2011.

In addition, the Company is authorized to grant up to 300,000 deferred shares of common stock to executive officers of the Company under the 1994 Executive Performance Plan.

Under the 2003 Non-Employee Directors’ Stock Incentive Plan, a plan approved by stockholders, the Company may grant up to 1.5 million shares (including options, restricted stock and deferred stock) to non-employee directors over the 10-year duration of the program, subject to an annual aggregate award limit of 25,000 shares for each individual director. In 2010, 38,940 shares of restricted stock with a weighted-average fair value of $30.00 per share were issued under this plan. The restricted stock issued under this plan cannot be sold, assigned, pledged or otherwise transferred by the non-employee director, until the director is no longer a member of the Board.

NOTE U – LIMITED PARTNERSHIP

In early 1998, a subsidiary of the Company purchased the 20 percent limited partner interests of outside investors in a consolidated subsidiary, Chemtech Royalty Associates L.P., for a fair value of $210 million in accordance with wind-up provisions in the partnership agreement. The limited partnership was renamed Chemtech II L.P. (“Chemtech II”). In June 1998, the Company contributed assets with an aggregate fair value of $783 million (through a wholly owned subsidiary) to Chemtech II and an outside investor acquired a limited partner interest in Chemtech II totaling 20 percent in exchange for $200 million. In September 2000, the Company contributed additional assets with an aggregate fair value of $18 million (through a wholly owned subsidiary) to Chemtech II. During the second quarter of 2008, the minority outside investor presented the Company with a liquidation notice, resulting in Dow’s election to purchase the outside investor’s share in the partnership for $200 million. The transaction was completed in the second quarter of 2008.

120

Prior to the sale of its interest, the outside investor in Chemtech II received a cumulative annual priority return on its investment and participated in residual earnings. For financial reporting purposes, the assets (other than intercompany loans, which were eliminated), liabilities, results of operations and cash flows of the partnership and subsidiaries were included in the Company’s consolidated financial statements, and the outside investor’s limited partner interest was included in “Noncontrolling interests” in the consolidated balance sheets.

NOTE V – PREFERRED SECURITIES OF SUBSIDIARIES

The following transactions were entered into for the purpose of providing diversified sources of funds to the Company.

In July 1999, Tornado Finance V.O.F., a former consolidated foreign subsidiary of the Company, issued $500 million of preferred securities in the form of preferred partnership units. The units provided a distribution of 7.965 percent, could be redeemed in 2009 or thereafter, and could be called at any time by the subsidiary. On June 4, 2009, the preferred partner notified Tornado Finance V.O.F. that the preferred partnership units would be redeemed in full on July 9, 2009, as permitted by the terms of the partnership agreement. On July 9, 2009, the preferred partnership units and accrued dividends were redeemed for a total of $520 million. Upon redemption, Tornado Finance V.O.F. was dissolved. The distributions were included in “Net income attributable to noncontrolling interests” in the consolidated statements of income.

In September 2001, Hobbes Capital S.A. (“Hobbes”), a former consolidated foreign subsidiary of the Company, issued $500 million of preferred securities in the form of equity certificates. The certificates provided a floating rate of return (which could be reinvested) based on LIBOR. During the third quarter of 2008, the other partner of Hobbes redeemed its $674 million ownership in Hobbes. The minority ownership was redeemed in a non-cash transaction in exchange for a three-year note payable with a floating rate based on LIBOR, which was repaid in September 2009. Prior to redemption, the preferred return was included in “Net income attributable to noncontrolling interests” in the consolidated statements of income.

NOTE W – REDEEMABLE PREFERRED STOCKS

Cumulative Perpetual Preferred Stock, Series B

With the April 1, 2009 acquisition of Rohm and Haas, certain trusts established by members of the Haas family (the “Haas Trusts”) and Paulson & Co. Inc. (“Paulson”) purchased from the Company Cumulative Perpetual Preferred Stock, Series B (“preferred series B”) in the amount of 2.5 million shares (Haas Trusts – 1.5 million shares; Paulson – 1.0 million shares) for an aggregate price of $2.5 billion (Haas Trusts – $1.5 billion; Paulson – $1.0 billion). Under the terms of the preferred series B, the holders were entitled to cumulative dividends at a rate of 7 percent per annum in cash and 8 percent per annum either in cash or as an increase in the liquidation preference of the preferred series B, at the Company’s option.

In May 2009, the Company entered into a purchase agreement with the Haas Trusts and Paulson, whereby the Haas Trusts and Paulson agreed to sell to the Company their shares of the preferred series B in consideration for shares of the Company’s common stock and/or notes, at the discretion of the Company. Pursuant to the purchase agreement, the Company issued 83.3 million shares of its common stock to the Haas Trusts and Paulson in consideration for the purchase of 1.2 million shares of preferred series B held by the Haas Trusts and Paulson. In a separate transaction as part of a $6 billion offering of senior notes, the Company issued $1.35 billion aggregate principal amount of 8.55 percent notes due 2019 to the Haas Trusts and Paulson in consideration for the purchase of the remaining 1.3 million shares of preferred series B at par plus accrued dividends. Upon the consummation of these transactions, all shares of preferred series B were retired. For additional information concerning the common stock and debt issuances, see Notes P and X.

Cumulative Convertible Perpetual Preferred Stock, Series C

With the April 1, 2009 acquisition of Rohm and Haas, the Haas Trusts invested $500 million in Cumulative Convertible Perpetual Preferred Stock, Series C (“preferred series C”). Under the terms of the preferred series C, prior to June 8, 2009, the holders were entitled to cumulative dividends at a rate of 7 percent per annum in cash and 8 percent per annum either in cash or as an increase in the liquidation preference of the preferred series C, at the Company’s option. On and after June 8, 2009, the Company would have been required to pay cumulative dividends of 12 percent per annum in cash.

The preferred series C shares would automatically convert to common stock on the date immediately following the ten full trading days commencing on the date on which there was an effective shelf registration statement relating to the common stock underlying the preferred series C, if such registration statement was effective prior to June 8, 2009. On May 26, 2009, the Company entered into an underwriting agreement and filed the corresponding shelf registration statement to effect the conversion of preferred series C into the Company’s common stock in accordance with the terms of the preferred series C.

121

Under the terms of the preferred series C, the shares of preferred series C would convert into shares of the Company’s common stock at a conversion price per share of common stock based upon 95 percent of the average of the common stock volume-weighted average price for the ten trading days preceding the conversion. After ten full trading days and upon the automatic conversion of the preferred series C, the Company issued 31.0 million shares of the Company’s common stock to the Haas Trusts on June 9, 2009, and all shares of preferred series C were retired (see Note X).

NOTE X – STOCKHOLDERS’ EQUITY

Cumulative Convertible Perpetual Preferred Stock, Series A

Equity securities in the form of Cumulative Convertible Perpetual Preferred Stock, Series A (“preferred series A”) were issued on April 1, 2009 to Berkshire Hathaway Inc. in the amount of $3 billion (3 million shares) and the Kuwait Investment Authority in the amount of $1 billion (1 million shares). The Company will pay cumulative dividends on preferred series A at a rate of 8.5 percent per annum in either cash, shares of common stock, or any combination thereof, at the option of the Company. Dividends may be deferred indefinitely, at the Company’s option. If deferred, common stock dividends must also be deferred. Any past due and unpaid dividends will accrue additional dividends at a rate of 10 percent per annum, compounded quarterly. If dividends are deferred for any six quarters, the preferred series A shareholders may elect two directors to the Company’s Board of Directors until all past due dividends are paid. Ongoing dividends related to preferred series A are $85 million per quarter; no dividends had been deferred at December 31, 2010.

Shareholders of preferred series A may convert all or any portion of their shares, at their option, at any time, into shares of the Company’s common stock at an initial conversion rate of 24.2010 shares of common stock for each share of preferred series A. Under certain circumstances, the Company will be required to adjust the conversion rate. On or after the fifth anniversary of the issuance date, if the common stock price exceeds $53.72 per share for any 20 trading days in a consecutive 30-day window, the Company may, at its option, at any time, in whole or in part, convert preferred series A into common stock at the then applicable conversion rate. Upon conversion, accrued and unpaid dividends will be payable, at the option of the Company, in either cash, shares of common stock, or any combination thereof.

Common Stock

On May 6, 2009, the Company launched a public offering of 150.0 million shares of its common stock at a price of $15.00 per share. Included in the 150.0 million shares offered to the public were 83.3 million shares issued to the Haas Trusts and Paulson in consideration for shares of preferred series B held by the Haas Trusts and Paulson (see Note W). Gross proceeds were $2,250 million, of which the Company’s net proceeds (after underwriting discounts and commissions) were $966 million for the sale of the Company’s 66.7 million shares.

On May 26, 2009, the Company entered into an underwriting agreement and filed the corresponding shelf registration statement to effect the conversion of the preferred series C into shares of the Company’s common stock (see Note W). On June 9, 2009, following the end of the sale period and determination of the share conversion amount, the Company issued 31.0 million shares to the Haas Trusts.

The Company issues common stock shares for purchases under the Employees’ Stock Purchase Plan (“ESPP”) out of treasury stock or as new common stock shares. The number of new common stock shares issued to employees under the Company’s ESPP was 10.0 million in 2010. No new common shares were issued to ESPP participants in 2009 or 2008, as all share issuances were satisfied from treasury stock.

Retained Earnings

There are no significant restrictions limiting the Company’s ability to pay dividends.

Undistributed earnings of nonconsolidated affiliates included in retained earnings were $2,264 million at December 31, 2010 and $1,826 million at December 31, 2009.

Employee Stock Ownership Plan

The Company has the Dow Employee Stock Ownership Plan (the “ESOP”), which is an integral part of The Dow Chemical Company Employees’ Savings Plan (the “Plan”). A significant majority of full-time employees in the United States are eligible to participate in the Plan. The Company uses the ESOP to provide the Company’s matching contribution in the form of the Company’s stock to Plan participants.

In connection with the acquisition of Rohm and Haas (see Note D), $552 million in cash was paid to the Rohm and Haas Company Employee Stock Ownership Plan (the “Rohm and Haas ESOP”) for 7.0 million shares of Rohm and Haas common stock held by the Rohm and Haas ESOP on April 1, 2009. On the date of the acquisition, the Rohm and Haas ESOP was

122

merged into the Plan, and the Company assumed the $78 million balance of debt at 9.8 percent interest with final maturity in 2020 that was used to finance share purchases by the Rohm and Haas ESOP in 1990. The outstanding balance of the debt was $64 million at December 31, 2010.

On May 11, 2009, the Company sold 36.7 million shares of common stock (from treasury stock) to the ESOP at a price of $15.0561 per share for a total of $553 million. The treasury stock was carried at an aggregate historical cost of $1,529 million.

Dividends on unallocated shares held by the ESOP are used by the ESOP to make debt service payments. Dividends on allocated shares are used by the ESOP to make debt service payments to the extent needed; otherwise, they are paid to the Plan participants. Shares are released for allocation to participants based on the ratio of the current year’s debt service to the sum of the principal and interest payments over the life of the loan. The shares are allocated to Plan participants in accordance with the terms of the Plan.

Compensation expense for allocated shares is recorded at the fair value of the shares on the date of allocation. ESOP shares that have not been released or committed to be released are not considered outstanding for purposes of computing basic and diluted earnings per share.

Compensation expense for ESOP shares allocated to plan participants was $81 million for the year ended December 31, 2010 ($48 million for the year ended December 31, 2009); no shares were allocated to plan participants in 2008. At December 31, 2010, 14.4 million shares out of a total 46.0 million shares held by the ESOP had been allocated to participants’ accounts; 0.9 million shares were released but unallocated; and 30.7 million shares, at a fair value of $1,050 million, were considered unearned.

Treasury Stock

On October 26, 2006, the Company announced that its Board of Directors had approved a share buy-back program, authorizing up to $2 billion to be spent on the repurchase of the Company’s common stock (the “2006 Program”). Purchases under the 2006 Program began in March 2007. In 2008, the Company purchased 21.9 million shares under the 2006 Program, bringing the total number of shares purchased under this program to 48.1 million and bringing the program to a close.

The total number of treasury shares purchased by the Company, including shares received from employees and non-employee directors to pay taxes owed to the Company as a result of the exercise of stock options or the delivery of deferred stock, was 0.5 million in 2010, 0.5 million in 2009 and 23.0 million in 2008.

The Company issues shares for options exercised as well as for the release of deferred and restricted stock out of treasury stock or as new common stock shares. The number of treasury shares issued to employees and non-employee directors under the Company’s option and purchase programs was 7.5 million in 2010, 8.7 million in 2009 and 7.0 million in 2008.

NOTE Y – INCOME TAXES

Operating loss carryforwards amounted to $4,572 million at December 31, 2010 and $4,550 million at December 31, 2009. At December 31, 2010, $405 million of the operating loss carryforwards were subject to expiration in 2011 through 2015. The remaining operating loss carryforwards expire in years beyond 2015 or have an indefinite carryforward period. Tax credit carryforwards at December 31, 2010 amounted to $479 million ($656 million at December 31, 2009), net of uncertain tax positions, of which $12 million is subject to expiration in 2011 through 2015. The remaining tax credit carryforwards expire in years beyond 2015.

Undistributed earnings of foreign subsidiaries and related companies that are deemed to be permanently invested amounted to $9,798 million at December 31, 2010, $8,707 million at December 31, 2009 and $8,043 million at December 31, 2008. It is not practicable to calculate the unrecognized deferred tax liability on those earnings.

123

The Company had valuation allowances that primarily related to the realization of recorded tax benefits on tax loss carryforwards from operations in the United States, Brazil and Asia Pacific of $682 million at December 31, 2010; valuation allowances of $721 million at December 31, 2009 primarily related to the realization of recorded tax benefits on tax loss carryforwards from operations in the United States, Brazil, Asia Pacific and Denmark.

The tax rate for 2010 was positively impacted by a high level of equity earnings as a percentage of total earnings, the release of a tax valuation allowance, a tax law change, and improved financial results in jurisdictions with tax rates that are lower than the U.S. statutory rate. These factors resulted in an effective tax rate of 17.2 percent for 2010.

The tax rate for 2009 was reduced by several factors: a significantly higher level of equity earnings as a percent of total earnings, favorable accrual-to-return adjustments in various geographies, the recognition of domestic losses and an improvement in financial results in jurisdictions with tax rates that are lower than the U.S. statutory rate. These factors resulted in an effective tax rate of negative 20.7 percent for 2009.

The tax rate for 2008 was negatively impacted by increased foreign taxes, declining financial results in jurisdictions with lower tax rates than the United States and goodwill impairment losses that are not deductible for tax purposes (see Note I). Additionally, during 2008, the Company determined that it was more likely than not that certain tax loss carryforwards in the United States and Asia Pacific would not be utilized due to deteriorating market conditions for the Company’s products in these areas, which resulted in increases in valuation allowances of $48 million in the United States and $24 million in Asia Pacific. These events resulted in an effective tax rate for 2008 that was higher than the U.S. statutory rate. The Company’s reported effective tax rate for 2008 was 51.0 percent.

Uncertain Tax Positions

At December 31, 2010, the total amount of unrecognized tax benefits was $319 million ($650 million at December 31, 2009), of which $297 million would impact the effective tax rate, if recognized ($610 million at December 31, 2009). The reduction in 2010 was primarily due to settlements of uncertain tax positions with tax authorities.

Interest and penalties associated with uncertain tax positions are recognized as components of the “Provision (Credit) for income taxes,” and totaled $6 million in 2010, $10 million in 2009 and $3 million in 2008. The Company’s accrual for interest and penalties was $58 million at December 31, 2010 and $68 million at December 31, 2009.

The Company is currently under examination in a number of tax jurisdictions. It is reasonably possible that these examinations may be resolved within twelve months. As a result, it is reasonably possible that the total gross unrecognized tax benefits of the Company at December 31, 2010 may be reduced by approximately $30 million to $60 million. The impact on the Company’s results of operations is not expected to be material.

The reserve for non-income tax contingencies related to issues in the United States and foreign locations was $156 million at December 31, 2010 and $189 million at December 31, 2009. This is management’s best estimate of the potential liability for non-income tax contingencies. Inherent uncertainties exist in estimates of tax contingencies due to changes in tax law, both legislated and concluded through the various jurisdictions’ tax court systems. It is the opinion of the Company’s management that the possibility is remote that costs in excess of those accrued will have a material adverse impact on the Company’s consolidated financial statements.

COMMITMENTS AND CONTINGENT LIABILITIES

Litigation

Breast Implant Matters

On May 15, 1995, Dow Corning Corporation (“Dow Corning”), in which the Company is a 50 percent shareholder, voluntarily filed for protection under Chapter 11 of the Bankruptcy Code to resolve litigation related to Dow Corning’s breast implant and other silicone medical products. On June 1, 2004, Dow Corning’s Joint Plan of Reorganization (the “Joint Plan”) became effective and Dow Corning emerged from bankruptcy. The Joint Plan contains release and injunction provisions resolving all tort claims brought against various entities, including the Company, involving Dow Corning’s breast implant and other silicone medical products.

To the extent not previously resolved in state court actions, cases involving Dow Corning’s breast implant and other silicone medical products filed against the Company were transferred to the U.S. District Court for the Eastern District of Michigan (the “District Court”) for resolution in the context of the Joint Plan. On October 6, 2005, all such cases then pending in the District Court against the Company were dismissed. Should cases involving Dow Corning’s breast implant and other silicone medical products be filed against the Company in the future, they will be accorded similar treatment. It is the opinion of the Company’s management that the possibility is remote that a resolution of all future cases will have a material adverse impact on the Company’s consolidated financial statements.

As part of the Joint Plan, Dow and Corning Incorporated agreed to provide a credit facility to Dow Corning in an aggregate amount of $300 million, which was reduced to $200 million effective June 1, 2010. The Company’s share of the credit facility was originally $150 million, but was reduced to $100 million effective June 1, 2010, and is subject to the terms and conditions stated in the Joint Plan. At December 31, 2010, no draws had been taken against the credit facility.

DBCP Matters

Numerous lawsuits have been brought against the Company and other chemical companies, both inside and outside of the United States, alleging that the manufacture, distribution or use of pesticides containing dibromochloropropane (“DBCP”) has caused personal injury and property damage, including contamination of groundwater. It is the opinion of the Company’s management that the possibility is remote that the resolution of such lawsuits will have a material adverse impact on the Company’s consolidated financial statements.

Environmental Matters

Accruals for environmental matters are recorded when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated based on current law and existing technologies. At December 31, 2010, the Company had accrued obligations of $607 million for probable environmental remediation and restoration costs, including $59 million for the remediation of Superfund sites. This is management’s best estimate of the costs for remediation and restoration with respect to environmental matters for which the Company has accrued liabilities, although the ultimate cost with respect to these particular matters could range up to approximately twice that amount. Consequently, it is reasonably possible that environmental remediation and restoration costs in excess of amounts accrued could have a material adverse impact on the Company’s results of operations, financial condition and cash flows. It is the opinion of the Company’s management, however, that the possibility is remote that costs in excess of the range disclosed will have a material adverse impact on the Company’s results of operations, financial condition and cash flows. Inherent uncertainties exist in these estimates primarily due to unknown conditions, changing governmental regulations and legal standards regarding liability, and emerging remediation technologies for handling site remediation and restoration. At December 31, 2009, the Company had accrued obligations of $619 million for probable environmental remediation and restoration costs, including $80 million for the remediation of Superfund sites.

The following table summarizes the activity in the Company's accrued obligations for environmental matters for the years ended December 31, 2010 and 2009:

Accrued Obligations for Environmental Matters
In millions	2010			2009
Balance at January 1	$	619		$	312
Additional accruals	159			271
Assumed from Rohm and Haas	—			159
Charges against reserve	(171		)	(143		)
Foreign currency impact	—			20
Balance at December 31	$	607		$	619

The amounts charged to income on a pretax basis related to environmental remediation totaled $158 million in 2010, $269 million in 2009 and $140 million in 2008. Capital expenditures for environmental protection were $173 million in 2010, $219 million in 2009 and $193 million in 2008.

Midland Off-Site Environmental Matters

On June 12, 2003, the Michigan Department of Natural Resources and Environment ("MDNRE," formerly the Michigan Department of Environmental Quality or MDEQ) issued a Hazardous Waste Operating License (the “License”) to the Company’s Midland, Michigan manufacturing site (the “Midland site”), which included provisions requiring the Company to conduct an investigation to determine the nature and extent of off-site contamination in the City of Midland soils; the Tittabawassee River and Saginaw River sediment and floodplain soils; and the Saginaw Bay; and, if necessary, undertake remedial action.

City of Midland

Matters related to the City of Midland remain under the primary oversight of the State of Michigan (the “State”) under the License, and the Company and the State are in ongoing discussions regarding the implementation of the requirements of the License.

Tittabawassee and Saginaw Rivers, Saginaw Bay

The Company, the U.S. Environmental Protection Agency (“EPA”) and the State entered into an administrative order on consent (“AOC”), effective January 21, 2010, that requires the Company to conduct a remedial investigation, a feasibility study and a remedial design for the Tittabawassee River, the Saginaw River and the Saginaw Bay, and pay the oversight costs of the EPA and the State under the authority of the Comprehensive Environmental Response, Compensation, and Liability Act (“CERCLA”). These actions, to be conducted under the lead oversight of the EPA, will build upon the investigative work completed under the State Resource Conservation Recovery Act (“RCRA”) program from 2005 through 2009. The Tittabawassee River, beginning at the Midland Site and extending down to the first six miles of the Saginaw River, are designated as the first Operable Unit for purposes of conducting the remedial investigation, feasibility study and remedial design work. This work will be performed in a largely upriver to downriver sequence for eight geographic segments of the Tittabawassee and upper Saginaw Rivers. The remainder of the Saginaw River and the Saginaw Bay are designated as a second Operable Unit and the work associated with that unit may also be geographically segmented. The AOC does not obligate the Company to perform removal or remedial action; that action can only be required by a separate order. The Company and the EPA will be negotiating orders separate from the AOC that will obligate the Company to perform remedial actions under the scope of work of the AOC.

Alternative Dispute Resolution Process

The Company; the EPA; the U.S. Department of Justice; and the natural resource damage trustees (the Michigan Office of the Attorney General; the MDNRE; the U.S. Fish and Wildlife Service; the U.S. Bureau of Indian Affairs and the Saginaw-Chippewa tribe), have been engaged in negotiations to seek to resolve potential governmental claims against the Company related to historical off-site contamination associated with the City of Midland, the Tittabawassee and Saginaw Rivers and the Saginaw Bay. The Company and the governmental parties started meeting in the fall of 2005 and entered into a Confidentiality Agreement in December 2005. The Company continues to conduct negotiations under the Federal Alternative Dispute Resolution Act with all of the governmental parties, except the EPA which withdrew from the alternative dispute resolution process on September 12, 2007.

On September 28, 2007, the Company and the natural resource damage trustees entered into a Funding and Participation Agreement that addressed the Company’s payment of past costs incurred by the natural resource damage trustees, payment of the costs of a trustee coordinator and a process to review additional cooperative studies that the Company might agree to fund or conduct with the natural resource damage trustees. On March 18, 2008, the Company and the natural resource damage trustees entered into a Memorandum of Understanding to provide a mechanism for the Company to fund cooperative studies related to the assessment of natural resource damages. On April 7, 2008, the natural resource damage trustees released their “Natural Resource Damage Assessment Plan for the Tittabawassee River System Assessment Area.”

At December 31, 2010, the accrual for these off-site matters was $32 million (included in the total accrued obligation of $607 million). At December 31, 2009, the Company had an accrual for these off-site matters of $25 million (included in the total accrued obligation of $619 million).

Environmental Matters Summary

It is the opinion of the Company’s management that the possibility is remote that costs in excess of those disclosed will have a material adverse impact on the Company’s results of operations, financial condition and cash flows.

Asbestos-Related Matters of Union Carbide Corporation

Union Carbide Corporation (“Union Carbide”), a wholly owned subsidiary of the Company, is and has been involved in a large number of asbestos-related suits filed primarily in state courts during the past three decades. These suits principally allege personal injury resulting from exposure to asbestos-containing products and frequently seek both actual and punitive damages. The alleged claims primarily relate to products that Union Carbide sold in the past, alleged exposure to asbestos-containing products located on Union Carbide’s premises, and Union Carbide’s responsibility for asbestos suits filed against a former Union Carbide subsidiary, Amchem Products, Inc. (“Amchem”). In many cases, plaintiffs are unable to demonstrate that they have suffered any compensable loss as a result of such exposure, or that injuries incurred in fact resulted from exposure to Union Carbide’s products.

Influenced by the bankruptcy filings of numerous defendants in asbestos-related litigation and the prospects of various forms of state and national legislative reform, the rate at which plaintiffs filed asbestos-related suits against various companies, including Union Carbide and Amchem, increased in 2001, 2002 and the first half of 2003. Since then, the rate of filing has significantly abated. Union Carbide expects more asbestos-related suits to be filed against Union Carbide and Amchem in the future, and will aggressively defend or reasonably resolve, as appropriate, both pending and future claims.

Based on a study completed by Analysis, Research & Planning Corporation (“ARPC”) in January 2003, Union Carbide increased its December 31, 2002 asbestos-related liability for pending and future claims for the 15-year period ending in 2017 to $2.2 billion, excluding future defense and processing costs. Since then, Union Carbide has compared current asbestos claim and resolution activity to the results of the most recent ARPC study at each balance sheet date to determine whether the accrual continues to be appropriate. In addition, Union Carbide has requested ARPC to review Union Carbide’s historical asbestos claim and resolution activity each November since 2004 to determine the appropriateness of updating the most recent ARPC study.

In November 2008, Union Carbide requested ARPC to review Union Carbide’s historical asbestos claim and resolution activity and determine the appropriateness of updating its then most recent study completed in December 2006. In response to that request, ARPC reviewed and analyzed data through October 31, 2008. The resulting study, completed by ARPC in December 2008, stated that the undiscounted cost of resolving pending and future asbestos-related claims against Union Carbide and Amchem, excluding future defense and processing costs, through 2023 was estimated to be between $952 million and $1.2 billion. As in its earlier studies, ARPC provided estimates for a longer period of time in its December 2008 study, but also reaffirmed its prior advice that forecasts for shorter periods of time are more accurate than those for longer periods of time.

In December 2008, based on ARPC’s December 2008 study and Union Carbide’s own review of the asbestos claim and resolution activity, Union Carbide decreased its asbestos-related liability for pending and future claims to $952 million, which covered the 15-year period ending 2023, excluding future defense and processing costs. The reduction was $54 million and is shown as “Asbestos-related credits” in the consolidated statements of income. At December 31, 2008, the asbestos-related liability for pending and future claims was $934 million.

In November 2009, Union Carbide requested ARPC to review Union Carbide’s 2009 asbestos claim and resolution activity and determine the appropriateness of updating its December 2008 study. In response to that request, ARPC reviewed and analyzed data through October 31, 2009. In December 2009, ARPC stated that an update of its study would not provide a more likely estimate of future events than the estimate reflected in its study of the previous year and, therefore, the estimate in that study remained applicable. Based on Union Carbide’s own review of the asbestos claim and resolution activity and ARPC’s response, Union Carbide determined that no change to the accrual was required. At December 31, 2009, Union Carbide’s asbestos-related liability for pending and future claims was $839 million.

In November 2010, Union Carbide requested ARPC to review Union Carbide’s historical asbestos claim and resolution activity and determine the appropriateness of updating its December 2008 study. In response to that request, ARPC reviewed and analyzed data through October 31, 2010. The resulting study, completed by ARPC in December 2010, stated that the undiscounted cost of resolving pending and future asbestos-related claims against Union Carbide and Amchem, excluding future defense and processing costs, through 2025 was estimated to be between $744 million and $835 million. As in its earlier studies, ARPC provided estimates for a longer period of time in its December 2010 study, but also reaffirmed its prior advice that forecasts for shorter periods of time are more accurate than those for longer periods of time.

In December 2010, based on ARPC’s December 2010 study and Union Carbide’s own review of the asbestos claim and resolution activity, Union Carbide decreased its asbestos-related liability for pending and future claims to $744 million, which covered the 15-year period ending 2025, excluding future defense and processing costs. The reduction was $54 million and was shown as “Asbestos-related credits” in the consolidated statements of income. At December 31, 2010, the asbestos-related liability for pending and future claims was $728 million.

At December 31, 2010, approximately 21 percent of the recorded liability related to pending claims and approximately 79 percent related to future claims. At December 31, 2009, approximately 23 percent of the recorded liability related to pending claims and approximately 77 percent related to future claims.

At December 31, 2002, Union Carbide increased the receivable for insurance recoveries related to its asbestos liability to $1.35 billion, substantially exhausting its asbestos product liability coverage. The insurance receivable related to the asbestos liability was determined by Union Carbide after a thorough review of applicable insurance policies and the 1985 Wellington Agreement, to which Union Carbide and many of its liability insurers are signatory parties, as well as other insurance settlements, with due consideration given to applicable deductibles, retentions and policy limits, and taking into account the solvency and historical payment experience of various insurance carriers. The Wellington Agreement and other agreements with insurers are designed to facilitate an orderly resolution and collection of Union Carbide’s insurance policies and to resolve issues that the insurance carriers may raise.

In September 2003, Union Carbide filed a comprehensive insurance coverage case, now proceeding in the Supreme Court of the State of New York, County of New York, seeking to confirm its rights to insurance for various asbestos claims and to facilitate an orderly and timely collection of insurance proceeds (the “Insurance Litigation”). The Insurance Litigation was filed against insurers that are not signatories to the Wellington Agreement and/or do not otherwise have agreements in place with Union Carbide regarding their asbestos-related insurance coverage, in order to facilitate an orderly resolution and collection of such insurance policies and to resolve issues that the insurance carriers may raise. Since the filing of the case, Union Carbide has reached settlements with several of the carriers involved in the Insurance Litigation, including settlements reached with two significant carriers in the fourth quarter of 2009. The Insurance Litigation is ongoing.

Union Carbide’s receivable for insurance recoveries related to its asbestos liability was $50 million at December 31, 2010 and $84 million at December 31, 2009. At December 31, 2010 and December 31, 2009, all of the receivable for insurance recoveries was related to insurers that are not signatories to the Wellington Agreement and/or do not otherwise have agreements in place regarding their asbestos-related insurance coverage.

In addition to the receivable for insurance recoveries related to its asbestos liability, Union Carbide had receivables for defense and resolution costs submitted to insurance carriers that have settlement agreements in place regarding their asbestos-related insurance coverage. The following table summarizes Union Carbide’s receivables related to its asbestos-related liability:

Receivables for Asbestos-Related Costs at December 31 In millions	2010		2009
Receivables for defense costs – carriers with settlement agreements	$	12	$	91
Receivables for resolution costs – carriers with settlement agreements	236		357
Receivables for insurance recoveries – carriers without settlement agreements	50		84
Total	$	298	$	532

Union Carbide expenses defense costs as incurred. The pretax impact for defense and resolution costs, net of insurance, was $73 million in 2010, $58 million in 2009 and $53 million in 2008, and was reflected in “Cost of sales.”

After a review of its insurance policies, with due consideration given to applicable deductibles, retentions and policy limits, after taking into account the solvency and historical payment experience of various insurance carriers; existing insurance settlements; and the advice of outside counsel with respect to the applicable insurance coverage law relating to the terms and conditions of its insurance policies, Union Carbide continues to believe that its recorded receivable for insurance recoveries from all insurance carriers is probable of collection.

The amounts recorded by Union Carbide for the asbestos-related liability and related insurance receivable described above were based upon current, known facts. However, future events, such as the number of new claims to be filed and/or received each year, the average cost of disposing of each such claim, coverage issues among insurers, and the continuing solvency of various insurance companies, as well as the numerous uncertainties surrounding asbestos litigation in the United States, could cause the actual costs and insurance recoveries for Union Carbide to be higher or lower than those projected or those recorded.

Because of the uncertainties described above, Union Carbide’s management cannot estimate the full range of the cost of resolving pending and future asbestos-related claims facing Union Carbide and Amchem. Union Carbide’s management believes that it is reasonably possible that the cost of disposing of Union Carbide’s asbestos-related claims, including future defense costs, could have a material adverse impact on Union Carbide’s results of operations and cash flows for a particular period and on the consolidated financial position of Union Carbide.

It is the opinion of Dow’s management that it is reasonably possible that the cost of Union Carbide disposing of its asbestos-related claims, including future defense costs, could have a material adverse impact on the Company’s results of operations and cash flows for a particular period and on the consolidated financial position of the Company.

Synthetic Rubber Industry Matters

In 2003, the U.S., Canadian and European competition authorities initiated separate investigations into alleged anticompetitive behavior by certain participants in the synthetic rubber industry. Certain subsidiaries of the Company (but as to the investigation in Europe only) have responded to requests for documents and are otherwise cooperating in the investigations.

On June 10, 2005, the Company received a Statement of Objections from the European Commission (the “EC”) stating that it believed that the Company and certain subsidiaries of the Company (the “Dow Entities”), together with other participants in the synthetic rubber industry, engaged in conduct in violation of European competition laws with respect to the butadiene rubber and emulsion styrene butadiene rubber businesses. In connection therewith, on November 29, 2006, the EC issued its decision alleging infringement of Article 81 of the Treaty of Rome and imposed a fine of Euro 64.575 million (approximately $85 million at that time) on the Dow Entities; several other companies were also named and fined. As a result, the Company recognized a loss contingency of $85 million related to the fine in the fourth quarter of 2006. The Company has appealed the EC’s decision. On October 13, 2009, the Court of First Instance held a hearing on the appeal of all parties. Subsequent to the imposition of the fine, the Company and/or certain subsidiaries of the Company became named parties in various related U.S., United Kingdom and Italian civil actions. The U.S. matter was settled in March 2010 through a confidential settlement agreement, with an immaterial impact on the Company’s consolidated financial statements.

Additionally, on March 10, 2007, the Company received a Statement of Objections from the EC stating that it believed that DuPont Dow Elastomers L.L.C. (“DDE”), a former 50:50 joint venture with E.I. du Pont de Nemours and Company (“DuPont”), together with other participants in the synthetic rubber industry, engaged in conduct in violation of European competition laws with respect to the polychloroprene business. This Statement of Objections specifically names the Company, in its capacity as a former joint venture owner of DDE. On December 5, 2007, the EC announced its decision to impose a fine on the Company, among others, in the amount of Euro 48.675 million (approximately $65 million). The Company previously transferred its joint venture ownership interest in DDE to DuPont in 2005, and DDE then changed its name to DuPont Performance Elastomers L.L.C. (“DPE”). In February 2008, DuPont, DPE and the Company each filed an appeal of the December 5, 2007 decision of the EC. Based on the Company’s allocation agreement with DuPont, the Company’s share of this fine, regardless of the outcome of the appeals, will not have a material adverse impact on the Company’s consolidated financial statements.

Rohm and Haas Pension Plan Matters

In December 2005, a federal judge in the U.S. District Court for the Southern District of Indiana (the “District Court”) issued a decision granting a class of participants in the Rohm and Haas Pension Plan (the “Rohm and Haas Plan”) who had retired from Rohm and Haas, now a wholly owned subsidiary of the Company, and who elected to receive a lump sum benefit from the Rohm and Haas Plan, the right to a cost-of-living adjustment (“COLA”) as part of their retirement benefit. In August 2007, the Seventh Circuit Court of Appeals affirmed the District Court’s decision, and in March 2008, the U.S. Supreme Court denied the Rohm and Haas Plan’s petition to review the Seventh Circuit’s decision. The case was returned to the District Court for further proceedings. In October 2008 and February 2009, the District Court issued rulings that have the effect of including in the class all Rohm and Haas retirees who received a lump sum distribution without a COLA from the Rohm and Haas Plan since January 1976. These rulings are subject to appeal, and the District Court has not yet determined the amount of the COLA benefits that may be due to the class participants. The Rohm and Haas Plan and the plaintiffs entered into a settlement agreement that, in addition to settling the litigation with respect to the Rohm and Haas retirees, provides for the amendment of the complaint and amendment of the Rohm and Haas Plan to include active employees in the settlement benefits. The District Court preliminarily approved the settlement on November 24, 2009 and, following a hearing on March 12, 2010, issued a final order approving the settlement on April 12, 2010. A group of objectors to the settlement filed an appeal from the final order. In November 2010, the District Court issued an order approving class counsel’s fee award petition in an amount consistent with the terms of the settlement. The same objectors also appealed this order. Both appeals are pending.

A pension liability associated with this matter of $185 million was recognized as part of the acquisition of Rohm and Haas on April 1, 2009. The liability, which was determined in accordance with the accounting guidance for contingencies, recognized the estimated impact of the above described judicial decisions on the long-term Rohm and Haas Plan obligations owed to the applicable Rohm and Haas retirees and active employees. At December 31, 2010, the Company had a liability of $186 million ($183 million at December 31, 2009) associated with this matter.

Other Litigation Matters

In addition to breast implant, DBCP, environmental and synthetic rubber industry matters, the Company is party to a number of other claims and lawsuits arising out of the normal course of business with respect to commercial matters, including product liability, governmental regulation and other actions. Certain of these actions purport to be class actions and seek damages in very large amounts. All such claims are being contested. Dow has an active risk management program consisting of numerous insurance policies secured from many carriers at various times. These policies provide coverage that will be utilized to minimize the financial impact, if any, of the contingencies described above.

Summary

Except for the possible effect of Union Carbide’s asbestos-related liability described above, it is the opinion of the Company’s management that the possibility is remote that the aggregate of all claims and lawsuits will have a material adverse impact on the Company's consolidated financial statements.

Purchase Commitments

The Company has numerous agreements for the purchase of ethylene-related products globally. The purchase prices are determined primarily on a cost-plus basis. Total purchases under these agreements were $714 million in 2010, $784 million in 2009 and $1,502 million in 2008. The Company’s take-or-pay commitments associated with these agreements at December 31, 2010 are included in the table below.

The Company also has various commitments for take-or-pay and throughput agreements. Such commitments are at prices not in excess of current market prices. The terms of all but two of these agreements extend from one to 25 years. One agreement has terms extending to 35 years and another has terms extending to 80 years. The determinable future commitments for these agreements are included for 10 years in the following table which presents the fixed and determinable portion of obligations under the Company’s purchase commitments at December 31, 2010:

In addition to the take-or-pay obligations at December 31, 2010, the Company had outstanding commitments which ranged from one to ten years for materials, services and other items used in the normal course of business of approximately $180 million. Such commitments were at prices not in excess of current market prices.

Guarantees

The Company provides a variety of guarantees, as described more fully in the following sections.

Guarantees

Guarantees arise during the ordinary course of business from relationships with customers and nonconsolidated affiliates when the Company undertakes an obligation to guarantee the performance of others (via delivery of cash or other assets) if specified triggering events occur. With guarantees, such as commercial or financial contracts, non-performance by the guaranteed party triggers the obligation of the Company to make payments to the beneficiary of the guarantee. The majority of the Company’s guarantees relate to debt of nonconsolidated affiliates, which have expiration dates ranging from less than one year to ten years, and trade financing transactions in Latin America and Asia Pacific, which typically expire within one year of their inception. The Company’s current expectation is that future payment or performance related to the non-performance of others is considered unlikely.

Residual Value Guarantees

The Company provides guarantees related to leased assets specifying the residual value that will be available to the lessor at lease termination through sale of the assets to the lessee or third parties.

The following tables provide a summary of the final expiration, maximum future payments and recorded liability reflected in the consolidated balance sheets for each type of guarantee:

Guarantees at December 31, 2010 In millions	Final Expiration	Maximum Future Payments		Recorded   Liability
Guarantees	2020	$	445	$	80

Asset Retirement Obligations

Dow has 188 manufacturing sites in 35 countries. Most of these sites contain numerous individual manufacturing operations, particularly at the Company’s larger sites. Asset retirement obligations are recorded as incurred and reasonably estimable, including obligations for which the timing and/or method of settlement are conditional on a future event that may or may not be within the control of the Company. The retirement of assets may involve such efforts as remediation and treatment of asbestos, contractually required demolition, and other related activities, depending on the nature and location of the assets, and retirement obligations are typically realized only upon demolition of those facilities. In identifying asset retirement obligations, the Company considers identification of legally enforceable obligations, changes in existing law, estimates of potential settlement dates and the calculation of an appropriate discount rate to be used in calculating the fair value of the obligations. Dow has a well-established global process to identify, approve and track the demolition of retired or to-be-retired facilities; and no assets are retired from service until this process has been followed. Dow typically forecasts demolition projects based on the usefulness of the assets; environmental, health and safety concerns; and other similar considerations. Under this process, as demolition projects are identified and approved, reasonable estimates are determined for the time frames during which any related asset retirement obligations are expected to be settled. For those assets where a range of potential settlement dates may be reasonably estimated, obligations are recorded. Dow routinely reviews all changes to items under consideration for demolition to determine if an adjustment to the value of the asset retirement obligation is required.

The Company has recognized asset retirement obligations for the following activities: demolition and remediation activities at manufacturing sites in the United States, Canada, Brazil, Chile, China and Europe; and capping activities at landfill sites in the United States, Canada, Brazil and Europe. The Company has also recognized conditional asset retirement obligations related to asbestos encapsulation as a result of planned demolition and remediation activities at manufacturing and administrative sites in the United States, Canada, Brazil, Chile, China and Europe. The aggregate carrying amount of conditional asset retirement obligations recognized by the Company (included in the asset retirement obligations balance) was $40 million at December 31, 2010 ($41 million at 2009).

The following table shows changes in the aggregate carrying amount of the Company’s asset retirement obligations:

Balance at December 31	$	99		$	101

(2) See Note E.

The discount rate used to calculate the Company’s asset retirement obligations at December 31, 2010 was 1.78 percent (2.45 percent at December 31, 2009). These obligations are included in the consolidated balance sheets as “Other noncurrent obligations.”

The Company has not recognized conditional asset retirement obligations for which a fair value cannot be reasonably estimated in its consolidated financial statements. Assets that have not been submitted/reviewed for potential demolition activities are considered to have continued usefulness and are generally still operating normally. Therefore, without a plan to demolish the assets or the expectation of a plan, such as shortening the useful life of assets for depreciation purposes in accordance with the accounting guidance related to property, plant and equipment, the Company is unable to reasonably forecast a time frame to use for present value calculations. As such, the Company has not recognized obligations for individual plants/buildings at its manufacturing sites where estimates of potential settlement dates cannot be reasonably made. In addition, the Company has not recognized conditional asset retirement obligations for the capping of its approximately 60 underground storage wells and 130 underground brine mining and other wells at Dow-owned sites when there are no plans or expectations of plans to exit the sites. It is the opinion of the Company’s management that the possibility is remote that such conditional asset retirement obligations, when estimable, will have a material adverse impact on the Company’s consolidated financial statements based on current costs.

PENSION PLANS AND OTHER POSTRETIREMENT BENEFITS

Acquisition of Rohm and Haas

With the April 1, 2009 acquisition of Rohm and Haas (see Note D), the Company assumed sponsorship of qualified and non-qualified pension and other postretirement benefit plans that provide defined benefits to U.S. and non-U.S. employees. As a result, the Company acquired the following plan assets and obligations from Rohm and Haas:

Plan Assets and Obligations Acquired from Rohm and Haas  on April 1, 2009 (1)
In millions	Defined Benefit Pension Plans		Other Postretirement Benefits
Fair value of plan assets	$	1,439	$	18
Projected benefit obligation	$	2,168	$	338

(1) Does not include plan assets and obligations of Morton that were sold to K+S on October 1, 2009; see Note E.

Pension Plans

The Company has defined benefit pension plans that cover employees in the United States and a number of other countries. The U.S. qualified plan covering the parent company is the largest plan. Benefits are based on length of service and the employee’s three highest consecutive years of compensation. Employees hired after January 1, 2008 earn benefits that are based on a set percentage of annual pay, plus interest.

The Company’s funding policy is to contribute to the plans when pension laws and/or economics either require or encourage funding. In 2010, Dow contributed $708 million to its pension plans, including contributions to fund benefit payments for its non-qualified supplemental plans. Dow expects to contribute approximately $700 million to its pension plans in 2011.

The weighted-average assumptions used to determine pension plan obligations and net periodic benefit costs for the plans are provided in the two tables below:

Weighted-Average Assumptions  for All Pension Plans	Benefit Obligations at December 31				Net Periodic Costs for the Year
	2010		2009		2010		2009
Discount rate	5.38	%	5.71	%	5.71	%	6.53	%
Rate of increase in future compensation levels	4.13	%	4.14	%	4.17	%	4.01	%
Expected long-term rate of return on plan assets	—		—		7.74	%	8.03	%

Weighted-Average Assumptions  for U.S. Pension Plans	Benefit Obligations at December 31				Net Periodic Costs for the Year
	2010		2009		2010		2009
Discount rate	5.51	%	5.97	%	5.97	%	6.82	%
Rate of increase in future compensation levels	4.50	%	4.50	%	4.50	%	4.31	%
Expected long-term rate of return on plan assets	—		—		8.16	%	8.46	%

The Company determines the expected long-term rate of return on plan assets by performing a detailed analysis of key economic and market factors driving historical returns for each asset class and formulating a projected return based on factors in the current environment. Factors considered include, but are not limited to, inflation, real economic growth, interest rate yield, interest rate spreads, and other valuation measures and market metrics. The expected long-term rate of return for each asset class is then weighted based on the strategic asset allocation approved by the governing body for each plan. The Company’s historical experience with the pension fund asset performance is also considered. A similar process is followed in determining the expected long-term rate of return for assets held in the Company’s other postretirement benefit plan trusts. The discount rates utilized to measure the pension and other postretirement obligations of the U.S. qualified plans are based on the yield on high-quality fixed income investments at the measurement date. Future expected actuarially determined cash flows of Dow’s major U.S. plans are matched against the Towers Watson RATE:Link yield curve (based on 60th to 90th percentile bond yields) to arrive at a single discount rate for each plan.

The accumulated benefit obligation for all defined benefit pension plans was $20.1 billion at December 31, 2010 and $18.9 billion at December 31, 2009.

Pension Plans with Accumulated Benefit Obligations in Excess  of Plan Assets at December 31
In millions	2010		2009
Projected benefit obligations	$	18,424	$	18,113
Accumulated benefit obligations	$	17,571	$	17,277
Fair value of plan assets	$	12,912	$	12,679

In addition to the U.S. qualified defined benefit pension plan, U.S. employees may participate in defined contribution plans (Employee Savings Plans or 401(k) plans) by contributing a portion of their compensation, which is partially matched by the Company. Defined contribution plans also cover employees in some subsidiaries in other countries, including Australia, Brazil, Canada, Italy, Spain and the United Kingdom. Expense recognized for all defined contribution plans was $184 million in 2010, $156 million in 2009 and $49 million in 2008.

Other Postretirement Benefits

The Company provides certain health care and life insurance benefits to retired employees. The Company’s plans outside of the United States are not significant; therefore, this discussion relates to the U.S. plans only. The plans provide health care benefits, including hospital, physicians’ services, drug and major medical expense coverage, and life insurance benefits. In general, for employees hired before January 1, 1993, the plans provide benefits supplemental to Medicare when retirees are eligible for these benefits. The Company and the retiree share the cost of these benefits, with the Company portion increasing as the retiree has increased years of credited service, although there is a cap on the Company portion. The Company has the ability to change these benefits at any time. Employees hired after January 1, 2008 are not covered under the plans.

The Company funds most of the cost of these health care and life insurance benefits as incurred. In 2010, Dow did not make any contributions to its other postretirement benefit plan trusts. Likewise, Dow does not expect to contribute assets to its other postretirement benefits plan trusts in 2011.

The weighted-average assumptions used to determine other postretirement benefit obligations and net periodic benefit costs for the U.S. plans are provided below:

U.S. Plan Assumptions for Other  Postretirement Benefits	Benefit Obligations at December 31				Net Periodic Costs for the Year
	2010		2009		2010		2009
Discount rate	5.15	%	5.69	%	5.69	%	7.11	%
Expected long-term rate of return on plan assets	—		—		4.35	%	5.15	%
Initial health care cost trend rate	8.70	%	9.13	%	9.13	%	9.71	%
Ultimate health care cost trend rate	5.00	%	5.00	%	5.00	%	6.00	%
Year ultimate trend rate to be reached	2019		2019		2019		2018

Increasing the assumed medical cost trend rate by one percentage point in each year would increase the accumulated postretirement benefit obligation at December 31, 2010 by less than $1 million and decrease the net periodic postretirement benefit cost for the year by $1 million. Decreasing the assumed medical cost trend rate by one percentage point in each year would increase the accumulated postretirement benefit obligation at December 31, 2010 by $23 million and the net periodic postretirement benefit cost for the year by $1 million.

Plan Assets

Plan assets consist mainly of equity and fixed income securities of U.S. and foreign issuers, and may include alternative investments such as real estate, private equity and absolute return strategies. At December 31, 2010, plan assets totaled $15.9 billion and included Company common stock with a value of $13 million (less than 1 percent of total plan assets). At December 31, 2009, plan assets totaled $14.6 billion and included Company common stock with a value of $11 million (less than 1 percent of total plan assets).

Investment Strategy and Risk Management for Plan Assets

The Company’s investment strategy for the plan assets is to manage the assets in relation to the liability in order to pay retirement benefits to plan participants while minimizing cash contributions from the Company over the life of the plans. This is accomplished by identifying and managing the exposure to various market risks, diversifying investments across various asset classes and earning an acceptable long-term rate of return consistent with an acceptable amount of risk, while considering the liquidity needs of the plans.

The plans are permitted to use derivative instruments for investment purposes, as well as for hedging the underlying asset and liability exposure and rebalancing the asset allocation. The plans use value at risk, stress testing, scenario analysis and Monte Carlo simulation to monitor and manage both risk in the portfolios and surplus risk.

Equity securities primarily include investments in large- and small-cap companies located in both developed and emerging markets around the world. Fixed income securities are primarily U.S. dollar based and include investment grade corporate bonds of companies diversified across industries, U.S. treasuries, non-U.S. developed market securities and U.S. agency mortgage-backed securities. Alternative investments primarily include investments in real estate, private equity limited partnerships and absolute return strategies. Other significant investment types include various insurance contracts; and interest rate, equity, commodity and foreign exchange derivative investments and hedges.

Strategic Weighted-Average Target Allocation of Plan Assets for All Significant Plans
Asset Category	Target Allocation
Equity securities	45	%
Fixed Income securities	35	%
Alternative investments	15	%
Other investments	5	%
Total	100	%

Concentration of Risk

The Company mitigates the credit risk of investments by establishing guidelines with investment managers that limit investment in any single issue or issuer to an amount that is not material to the portfolio being managed. These guidelines are monitored for compliance both by the Company and external managers. Credit risk related to derivative activity is mitigated by utilizing multiple counterparties and through collateral support agreements.

The JP Morgan Federal Agency money market fund is utilized as the sweep vehicle for the two largest U.S. plans, which from time to time can represent a significant investment. For one U.S. plan, approximately half of the liability is covered by a participating group annuity issued by Prudential Insurance Company.

For pension or other postretirement benefit plan assets classified as Level 1 measurements (measured using quoted prices in active markets), total fair value is either the price of the most recent trade at the time of the market close or the official close price, as defined by the exchange on which the asset is most actively traded on the last trading day of the period, multiplied by the number of units held without consideration of transaction costs.

For pension or other postretirement benefit plan assets classified as Level 2 measurements, where the security is frequently traded in less active markets, fair value is based on the closing price at the end of the period; where the security is less frequently traded, fair value is based on the price a dealer would pay for the security or similar securities, adjusted for any terms specific to that asset or liability. Market inputs are obtained from well-established and recognized vendors of market data and subjected to tolerance/quality checks. For derivative assets and liabilities, standard industry models are used to calculate the fair value of the various financial instruments based on significant observable market inputs, such as foreign exchange rates, commodity prices, swap rates, interest rates and implied volatilities obtained from various market sources.

Some pension or other postretirement benefit plan assets are held in funds where a net asset value is calculated based on the fair value of the underlying assets and the number of shares owned. The classification of the fund (Level 1, 2 or 3 measurements) is determined based on the classification of the significant holdings within the fund. For all other pension or other postretirement benefit plan assets for which observable inputs are used, fair value is derived through the use of fair value models, such as a discounted cash flow model or other standard pricing models.

For pension or other postretirement benefit plan assets classified as Level 3 measurements, total fair value is based on significant unobservable inputs including assumptions where there is little, if any, market activity for the investment. Investment managers or fund managers provide valuations of the investment on a monthly or quarterly basis. These valuations are reviewed for reasonableness based on applicable sector, benchmark and company performance. Adjustments to valuations are made where appropriate. Where available, audited financial statements are obtained and reviewed for the investments as support for the manager’s investment valuation.

The following tables summarize the changes in fair value of Level 3 pension plan assets for the years ended December 31, 2009 and 2010:

RESTRUCTURING

2009 Restructuring

On June 30, 2009, the Company’s Board of Directors approved a restructuring plan related to the Company’s acquisition of Rohm and Haas Company (“Rohm and Haas”) as well as actions to advance the Company’s strategy and to respond to continued weakness in the global economy. The restructuring plan included the elimination of approximately 2,500 positions primarily resulting from synergies to be achieved as a result of the acquisition of Rohm and Haas. In addition, the plan included the shutdown of a number of manufacturing facilities. These actions are expected to be completed primarily by the end of 2011. As a result of the restructuring activities, the Company recorded pretax restructuring charges of $677 million in the second quarter of 2009, consisting of asset write-downs and write-offs of $454 million, costs associated with exit or disposal activities of $68 million and severance costs of $155 million. The impact of the charges is shown as “Restructuring charges” in the consolidated statements of income and was reflected in the Company’s segment results as shown in the following table, which also reflects adjustments made in 2009 to the 2009 plan, the 2008 plan (as discussed below and in the sections titled “2008 Restructuring”) and the 2007 plan.

Details regarding the components of the 2009 restructuring charges and adjustments to restructuring charges are discussed below:

Impairment of Long-Lived Assets and Other Assets

The restructuring charges related to the write-down or write-off of assets totaled $454 million. Write-downs were related to Dow’s facilities located in Hahnville and Plaquemine, Louisiana; the United States Federal Trade Commission (“FTC”) required divestiture of certain acrylic monomer and specialty latex assets in North America; and other small manufacturing facilities where the acquisition of Rohm and Haas resulted in overlapping manufacturing capabilities. Details regarding these write-downs or write-offs are as follows:

• Due to continued weakness in the global economy, the decision was made to shut down a number of hydrocarbon and basic chemicals facilities, with an impact of $126 million, including the following:

◦ Ethylene manufacturing facility in Hahnville, Louisiana. A write-off of the net book value of the related buildings, machinery and equipment against the Feedstocks and Energy segment was recorded. The facility shut down in the second quarter of 2009.

◦ Ethylene oxide/ethylene glycol manufacturing facility in Hahnville, Louisiana. A write-off of the net book value of the related buildings, machinery and equipment against the Feedstocks and Energy segment was recorded. The facility shut down in the second quarter of 2009.

◦ Ethylene dichloride and vinyl chloride monomer manufacturing facility in Plaquemine, Louisiana. A write-down of the net book value of the related buildings, machinery and equipment against the Feedstocks and Energy segment was recorded. The facility will shut down in mid-2011.

• With the completion of the Company’s acquisition of Rohm and Haas, the following charges were recognized:

◦ Due to an expected loss arising from the FTC required divestitures of certain acrylic monomer and specialty latex assets within eight months of the closing of the acquisition of Rohm and Haas, the Company recognized an impairment charge of $205 million against the Coatings and Infrastructure Solutions segment in the second quarter of 2009. The divestiture of the assets was completed in January 2010 (see Note E).

◦ The decision was made to shut down a number of small manufacturing facilities to optimize the assets of the Company. Write-downs of $96 million were recorded in the second quarter of 2009, primarily impacting the Electronic and Functional Materials ($46 million) and Coatings and Infrastructure Solutions ($48 million) segments.

The restructuring charges in the second quarter of 2009 also included the write-off of capital project spending ($20 million) and other assets ($7 million) associated with plant closures. These charges were reflected in the results of the operating segments impacted by the restructuring activities.

Costs Associated with Exit or Disposal Activities

The restructuring charges for costs associated with exit or disposal activities totaled $68 million in the second quarter of 2009 and included environmental remediation of $64 million, impacting Corporate, with the remainder relating to contract termination fees and other charges. In the fourth quarter of 2009, the Company increased the reserve by $13 million to reflect additional expense for pension settlements related to the Rohm and Haas acquisition.

Severance Costs

The restructuring charges included severance of $155 million for the separation of approximately 2,500 employees under the terms of the Company’s ongoing benefit arrangements, primarily over two years. These costs were charged against Corporate. At December 31, 2009, severance of $72 million had been paid and a currency adjusted liability of $84 million remained for approximately 1,221 employees. At December 31, 2010, severance of $149 million had been paid and a currency adjusted liability of $6 million remained for approximately 189 employees, with anticipated departure dates scheduled primarily in the first quarter of 2011.

The following table summarizes the activities related to the Company’s restructuring reserve:

Reserve balance at December 31, 2010	$	—		$	68		$	6		$	74

Dow expects to incur future costs related to its restructuring activities, as the Company continually looks for ways to enhance the efficiency and cost effectiveness of its operations, and to ensure competitiveness across its businesses and across geographic areas. Future costs are expected to include demolition costs related to the closed facilities, which will be recognized as incurred. The Company also expects to incur additional employee-related costs, including involuntary termination benefits, related to its other optimization activities. These costs cannot be reasonably estimated at this time.

2010 Adjustments to 2009 and 2008 Restructuring Plans

In the first quarter of 2010, the Company recorded an additional $8 million charge to adjust the impairment of long-lived assets and other assets related to the FTC required divestitures completed in the first quarter of 2010, and an additional $8 million charge related to the shutdown of a small manufacturing facility under the 2009 restructuring plan. The impact of these charges is shown as “Restructuring charges” in the consolidated statements of income and was reflected in the following operating segments: Electronic and Functional Materials ($8 million) and Coatings and Infrastructure Solutions ($8 million).

In the second quarter of 2010, the Company recorded additional restructuring charges of $13 million, which included the write-off of other assets of $5 million, additional costs associated with exit or disposal activities of $7 million and additional severance of $1 million related to the FTC required divestitures that were included in the 2009 restructuring plan. The impact of these charges is shown as “Restructuring charges” in the consolidated statements of income and was reflected in Coatings and Infrastructure Solutions ($12 million) and Corporate ($1 million).

In the fourth quarter of 2010, the Company decreased the severance reserve for the 2008 restructuring plan by $3 million to adjust the reserve to the remaining future payments. The impact of this adjustment is shown as “Restructuring charges” in the consolidated statements of income and was reflected in Corporate.

2009 Adjustments to 2008 and 2007 Restructuring Plans

In the first quarter of 2009, the Company increased the severance reserve for the 2008 restructuring plan by $19 million, for an additional workforce reduction of approximately 500 employees. The increase was reflected in Corporate.

In the second quarter of 2009, the Company reduced the 2007 restructuring reserve related to contract termination fees by $15 million as a result of the Company’s acquisition of Rohm and Haas, impacting the Agricultural Sciences segment. The initial liability established in 2007 included contract termination fees related to the cancellation of contract manufacturing agreements between the Company and Rohm and Haas. Following completion of the acquisition, the liability for these fees was reversed.

In the fourth quarter of 2009, the Company reduced the severance reserve for the 2007 restructuring plan by $5 million as redeployment opportunities for affected employees were identified. The decrease was reflected in Corporate.

Restructuring Reserve Assumed from Rohm and Haas

Included in liabilities assumed in the April 1, 2009 acquisition of Rohm and Haas was a reserve of $122 million for severance and employee benefits for the separation of 1,255 employees under the terms of Rohm and Haas’ ongoing benefit arrangement. The separations resulted from plant shutdowns, production schedule adjustments, productivity improvements and reductions in support services. In the fourth quarter of 2009, the Company decreased the severance reserve assumed from Rohm and Haas by $9 million, recorded in “Cost of sales,” to adjust the reserve to the expected future severance payments. In the nine-month period following the acquisition, severance of $43 million was paid, leaving a currency adjusted liability of $68 million for approximately 552 employees at December 31, 2009.

In the second quarter of 2010, the Company decreased the restructuring reserve $10 million due to the divestiture of the Powder Coatings business and to adjust the reserve to expected future severance payments. In the second half of 2010, the Company decreased the restructuring reserve $24 million to adjust the reserve to expected future severance payments. The impact of these adjustments is shown as “Cost of sales” in the consolidated statements of income and was reflected in Corporate. In 2010, severance of $25 million was paid, leaving a currency adjusted liability of $12 million at December 31, 2010; $5 million for employees who have left the Company and will continue to receive annuity payments primarily through the third quarter of 2011 and $7 million for approximately 44 employees. Cash payments are expected to be complete by mid-2011.

2008 Restructuring

On December 5, 2008, the Company’s Board of Directors approved a restructuring plan as part of a series of actions to advance the Company’s strategy and respond to the severe economic downturn. The restructuring plan included the shutdown of a number of facilities and a global workforce reduction, which were substantially completed in 2010. As a result of the shutdowns and global workforce reduction, the Company recorded pretax restructuring charges of $785 million in the fourth quarter of 2008. The charges consisted of asset write-downs and write-offs of $336 million, costs associated with exit or disposal activities of $128 million and severance costs of $321 million. The impact of the charges is shown as “Restructuring charges” in the consolidated statements of income and was reflected in the Company’s segment results as shown in the following table, which also reflects adjustments made in 2008 to the 2007 and 2006 restructuring charges.

Details regarding the components of the 2008 restructuring charges are discussed below:

Impairment of Long-Lived Assets and Other Assets

The restructuring charges related to the write-down or write-off of assets in 2008 totaled $336 million and included the impact of plant closures and impairments of $288 million. The most significant write-downs were related to Dow’s facilities located in Oyster Creek, Freeport, Seadrift and Texas City, Texas; Pittsburg, California; Terneuzen, The Netherlands; Varennes, Quebec, Canada; Plaquemine, Louisiana; Aratu, Brazil; King’s Lynn and Wilton, England; assets related to the pending sale of the automotive sealants business in Europe; and project investment costs related to a potential joint venture in Oman. Details regarding these write-downs or write-offs are as follows:

• Due to a severe economic downturn, the Company decided in the fourth quarter of 2008 to shut down a number of facilities, including the following:

◦ Chlor-alkali manufacturing facility in Oyster Creek, Texas. A $31 million write-off of the net book value of the related buildings, machinery and equipment against the Feedstocks and Energy segment was recorded in the fourth quarter of 2008. This facility was shut down in the first quarter of 2009.

◦ Styrene and styrene derivatives manufacturing facilities principally in Freeport, Texas; Pittsburg, California; Terneuzen, The Netherlands; King’s Lynn, England; and Varennes, Canada. A $37 million write-off of the net book value of the related buildings, machinery and equipment was recorded in the fourth quarter of 2008 against the Feedstocks and Energy ($14 million), Performance Plastics ($6 million), Performance Materials ($10 million) and Coatings and Infrastructure Solutions ($2 million) segments, as well as Corporate ($5 million). The facilities were shut down in the fourth quarter of 2009.

◦ Facilities that manufacture NORDEL^TM hydrocarbon rubber in Seadrift, Texas, and TYRIN^TM chlorinated polyethylene in Plaquemine, Louisiana. A $36 million write-down of the net book value of the related buildings, machinery and equipment against the Performance Plastics ($22 million) and Performance Materials ($14 million) segments was recorded in the fourth quarter of 2008. Both facilities were closed in the first quarter of 2009.

◦ Solution vinyl resin manufacturing facilities in Texas City, Texas. A $26 million write-down of the net book value of the related buildings, machinery and equipment against the Performance Materials segment was recorded in the fourth quarter of 2008. This plant was shut down in the third quarter of 2009.

◦ Perchloroethylene/carbon tetrachloride manufacturing facility in Aratu, Brazil. An $11 million write-off of the net book value of the related buildings, machinery and equipment against the Performance Materials segment was recorded in the fourth quarter of 2008. This facility was closed in the second quarter of 2010.

◦ In addition to the locations described above, the restructuring charges for plant closures included $26 million related to the shutdown of several small production facilities.

• The Company decided in the fourth quarter of 2008 to pursue strategic alternatives regarding its Wilton, England, ethylene oxide/ethylene glycol (“EO/EG”) plant. Based on the results of asset impairment testing, an impairment charge of $30 million against the Feedstocks and Energy segment was recorded in the fourth quarter of 2008. The plant was shut down in January 2010.

• Due to an expected loss on the pending sale of the automotive sealants business in Europe, an impairment charge of $8 million against the Performance Materials segment was recorded in the fourth quarter of 2008. The business was sold in the first quarter of 2009.

• Due to a change in scope, the Company’s investment (primarily engineering costs) in a project to form a joint venture to design, build and operate a petrochemical complex in Oman was written down. An $83 million write-down of the project-related spending against the Performance Plastics segment was recorded in the fourth quarter of 2008.

The restructuring charges in the fourth quarter of 2008 also included the write-off of capital project spending ($13 million); spare parts ($9 million) and catalysts ($6 million) associated with plant closures; other assets ($5 million); as well as a loss on the sale of inventory ($15 million) associated with the divestiture of the automotive sealants business in Europe. These write-offs were related to the businesses involved in the shutdown of assets and were therefore reflected in the results of various operating segments.

Costs Associated with Exit or Disposal Activities

The restructuring charges for costs associated with exit or disposal activities totaled $128 million in 2008 and included pension curtailment costs and termination benefits of $88 million reflected in Corporate; and environmental remediation and asbestos abatement of $40 million primarily impacting Performance Materials and Corporate.

Severance Costs

As a result of the Company’s decision to shut down assets around the world and implement a global workforce reduction, the restructuring charges included severance of $321 million for the separation of approximately 3,000 employees under the terms of Dow’s ongoing benefit arrangements. These costs were charged against Corporate. In the first quarter of 2009, the Company increased the severance reserve by $19 million, including approximately 500 additional employees. At December 31, 2009, severance of $289 million had been paid and a currency adjusted liability of $53 million remained for approximately 293 employees. In the fourth quarter of 2010, the Company decreased the severance reserve by $3 million to adjust the reserve to the remaining future payments. The impact of this adjustment is shown as “Restructuring charges” in the consolidated statements of income and was reflected in Corporate. At December 31, 2010, severance of $316 million had been paid and employee separations were substantially complete. A currency adjusted liability of $22 million remained at December 31, 2010, largely for employees who have left the Company and will continue to receive annuity payments primarily through 2018.

The following table summarizes the activities related to the Company’s restructuring reserve:

The shutdowns and optimization activities related to the 2008 restructuring plan were substantially complete in 2010, with remaining liabilities primarily related to pension, environmental remediation and severance to be paid over time.

2008 Adjustments to 2007 and 2006 Restructuring Plans

In 2008, adjustments were made to the 2007 restructuring plan to increase the reserve for environmental remediation $5 million (impacting Corporate). The 2007 restructuring reserve was also increased $5 million for contract termination fees, reflected in Performance Materials ($2 million) and Agricultural Sciences ($3 million). In the fourth quarter of 2008, Pétromont, a nonconsolidated affiliate, announced the permanent shutdown of its operations. As a result of this announcement, the Company recorded an additional charge of $50 million against the 2007 restructuring plan (impacting the Performance Plastics segment).

In 2008, adjustments were made to the 2006 restructuring plan to decrease the reserve for environmental remediation $3 million (impacting the Feedstocks and Energy segment) and to decrease the severance reserve $3 million (impacting Corporate).

On November 4, 2010, the Company issued $2.5 billion of debt securities in a public offering. The offering included $750 million aggregate principal amount of 2.50 percent notes due 2016 and $1.75 billion aggregate principal amount of 4.25 percent notes due 2020.

On March 9, 2009, the Company borrowed $3 billion under its Five Year Competitive Advance and Revolving Credit Facility Agreement, dated April 24, 2006 (“Agreement”); $1.6 billion of the funds were repaid on May 15, 2009; $0.5 billion of the funds were repaid on June 30, 2009; and the remaining $0.9 billion of the funds were repaid on December 30, 2009. The funds were due in April 2011 and bore interest at a variable London Interbank Offered Rate (“LIBOR”)-plus rate or Base Rate as defined in the Agreement. The Company used the funds to finance day-to-day operations, to repay indebtedness maturing in the ordinary course of business and for other general corporate purposes. In 2010, the Company replaced the Agreement with a new $3 billion Three Year Competitive Advance and Revolving Credit Facility Agreement dated June 4, 2010 (“Revolving Credit Facility”) with various U.S. and foreign banks. The Revolving Credit Facility has a maturity date in June 2013 and provides for interest at a LIBOR-plus rate or Base Rate as defined in the Revolving Credit Facility. At December 31, 2010, the full $3 billion credit facility was available to the Company.

Debt financing for the acquisition of Rohm and Haas was provided by a $9,226 million draw on a Term Loan Agreement dated September 8, 2008 (“Term Loan”) on April 1, 2009. The original maturity date of the Term Loan was April 1, 2010, provided however, that the maturity date could have been extended for an additional year at the option of the Company, for a maximum outstanding balance of $8.0 billion. Prepaid up-front debt issuance costs of $304 million were paid. Amortization of the prepaid costs was accelerated concurrent with the repayment of the Term Loan. The Term Loan was repaid through a combination of proceeds obtained through asset sales and the issuance of debt and equity securities. At December 31, 2009, the Term Loan balance was zero and the Term Loan was terminated.

On May 7, 2009, the Company issued $6 billion of debt securities in a public offering. The offering included $1.75 billion aggregate principal amount of 7.6 percent notes due 2014; $3.25 billion aggregate principal amount of 8.55 percent notes due 2019; and $1 billion aggregate principal amount of 9.4 percent notes due 2039. Aggregate principal amount of $1.35 billion of the 8.55 percent notes due 2019 were offered by accounts and funds managed by Paulson & Co. Inc. and trusts created by members of the Haas family. These investors received notes from the Company in payment for 1.3 million shares of the Company’s Perpetual Preferred Stock, Series B, at par plus accrued dividends (see Note W for further information). The Company used the net proceeds received from this offering for refinancing, renewals, replacements and refunding of outstanding indebtedness, including repayment of a portion of the Term Loan.

On August 4, 2009, the Company issued $2.75 billion of debt securities in a public offering. The offering included $1.25 billion aggregate principal amount of 4.85 percent notes due 2012; $1.25 billion aggregate principal amount of 5.90 percent notes due 2015; and $0.25 billion aggregate principal amount of LIBOR-plus based floating rate notes due 2011. The Company used the net proceeds received from this offering for refinancing, renewals, replacements and refunding of outstanding indebtedness, including repayment of a portion of the Term Loan.

The fair value of debt assumed from Rohm and Haas on April 1, 2009 of $2,576 million is reflected in the long-term debt table above. On August 21, 2009, the Company executed a buy-back of Euro 175 million of private placement debt acquired from Rohm and Haas and recognized a $56 million pretax loss on this early extinguishment, included in “Sundry income – net.” On September 8, 2010, the Company concluded a tender offer for any and all of $145 million of debentures acquired from Rohm and Haas, due June 2020. As a result of the tender offer, the Company redeemed $123 million of the debentures and recognized a $46 million pretax loss on this early extinguishment, included in “Sundry income – net.”

On September 28, 2009, Calvin Capital LLC, a wholly owned subsidiary of the Company, repaid a $674 million note payable, which was issued in September 2008.

The Company’s outstanding debt of $22.4 billion has been issued under indentures which contain, among other provisions, covenants with which the Company must comply while the underlying notes are outstanding. Such covenants include obligations to not allow liens on principal U.S. manufacturing facilities, enter into sale and lease-back transactions with respect to principal U.S. manufacturing facilities, or merge or consolidate with any other corporation, or sell or convey all or substantially all of the Company’s assets. The outstanding debt also contains customary default provisions. Failure of the Company to comply with any of these covenants could result in a default under the applicable indenture, which would allow the note holders to accelerate the due date of the outstanding principal and accrued interest on the subject notes.

The Company’s primary credit agreements contain covenant and default provisions in addition to the covenants set forth above with respect to the Company’s debt. Significant other covenants and default provisions related to these agreements include:

(a) the obligation to maintain the ratio of the Company’s consolidated indebtedness to consolidated capitalization at no greater than 0.65 to 1.00 at any time the aggregate outstanding amount of loans under the Revolving Credit Facility exceeds $500 million,

(b) a default if the Company or an applicable subsidiary fails to make any payment on indebtedness of $50 million or more when due, or any other default under the applicable agreement permits the acceleration of $200 million or more of principal, or results in the acceleration of $100 million or more of principal, and

(c) a default if the Company or any applicable subsidiary fails to discharge or stay within 30 days after the entry of a final judgment of more than $200 million.

Failure of the Company to comply with any of the covenants or default provisions could result in a default under the applicable credit agreement which would allow the lenders to not fund future loan requests and to accelerate the due date of the outstanding principal and accrued interest on any outstanding loans.

At December 31, 2010, management believes the Company was in compliance with all of the covenants and default provisions referred to above.

Equity Method Investments and Joint Ventures [Abstract]

Equity Method Investments Disclosure [Text Block]

NONCONSOLIDATED AFFILIATES AND RELATED COMPANY TRANSACTIONS

The Company’s investments in related companies accounted for using the equity method (“nonconsolidated affiliates”) were $3,453 million at December 31, 2010 and $3,224 million at December 31, 2009. At December 31, 2010, the carrying amount of the Company’s investments in nonconsolidated affiliates was $74 million more than its share of the investees’ net assets, exclusive of additional differences for Dow Corning Corporation (“Dow Corning”), MEGlobal and Equipolymers, which are discussed separately below. At December 31, 2009, the carrying amount of the Company’s investments in nonconsolidated affiliates was $52 million more than its share of the investees’ net assets, exclusive of additional differences for Dow Corning, MEGlobal, Equipolymers and Americas Styrenics LLC. Dividends received from the Company’s nonconsolidated affiliates were $668 million in 2010, $690 million in 2009 and $836 million in 2008.

On May 15, 1995, Dow Corning, in which the Company is a 50 percent shareholder, voluntarily filed for protection under Chapter 11 of the U.S. Bankruptcy Code (see Note N). As a result, the Company fully reserved its investment in Dow Corning and reserved its 50 percent share of equity earnings from that time through the third quarter of 2000. In November 2000, following affirmation of the Bankruptcy Court’s order confirming the Joint Plan of Reorganization (the “Joint Plan”), the Company reviewed the value of its investment in Dow Corning, revised its assessment of the recoverability of its investment, and determined that it had adequately provided for the other-than-temporary decline associated with the bankruptcy. On June 1, 2004, Dow Corning’s Joint Plan became effective and Dow Corning emerged from bankruptcy. Since May 1995, a difference between the Company’s 50 percent share of the underlying equity of Dow Corning and the carrying value of this investment has existed, and the Company considers the difference to be permanent. The Company’s investment in Dow Corning was $227 million less than the Company’s proportionate share of Dow Corning’s underlying net assets at December 31, 2010 and December 31, 2009.

At December 31, 2010, the Company’s investment in MEGlobal was $250 million less than the Company’s proportionate share of MEGlobal’s underlying net assets ($257 million less at December 31, 2009). This amount represents the difference between the value of certain assets of the joint venture and the Company’s related valuation on a U.S. GAAP basis, of which $60 million is being amortized over the remaining useful lives of the assets and $190 million represents the Company’s share of the joint venture’s goodwill.

At December 31, 2010, the Company’s investment in Equipolymers was $7 million less than the Company’s proportionate share of Equipolymers’ underlying net assets ($8 million less at December 31, 2009). This amount represents the difference between the value of certain assets of the joint venture and the Company’s related valuation on a U.S. GAAP basis, all of which is being amortized over the remaining useful lives of the assets. In the fourth quarter of 2009, the Company recognized an impairment loss of $65 million related to its investment in Equipolymers.

At December 31, 2009, the Company’s investment in Americas Styrenics LLC was $136 million less than the Company’s proportionate share of Americas Styrenics LLC’s underlying net assets. This amount represented the difference between the book value of assets contributed to the joint venture by the Company at the time of formation (May 1, 2008) and the Company’s 50 percent share of the total recorded value of the joint venture’s assets. The Company’s investment in Americas Styrenics LLC was sold on June 17, 2010, as part of the divestiture of Styron (see Note E).

See Note E for information regarding the divestiture of the Company’s investment in two additional nonconsolidated affiliates in 2009.

All of the nonconsolidated affiliates in which the Company has investments are privately held companies; therefore, quoted market prices are not available.

DIVESTITURES

Divestiture of the Styron Business Unit

On March 2, 2010, the Company announced the entry into a definitive agreement to sell the Styron business unit (“Styron”) to an affiliate of Bain Capital Partners. The definitive agreement specified the assets and liabilities related to the businesses and products to be included in the sale. On June 17, 2010, the sale was completed for $1,561 million, net of working capital adjustments and costs to sell, with proceeds subject to customary post-closing adjustments. The proceeds included a $75 million long-term note receivable. In addition, the Company elected to acquire a 7.5 percent equity interest in the resulting privately held, global materials company. Businesses and products sold included: Styrenics – polystyrene, acrylonitrile butadiene styrene, styrene acrylonitrile and expandable polystyrene; Emulsion Polymers; Polycarbonate and Compounds and Blends; Synthetic Rubber; and certain products from Dow Automotive Systems. Also included in the sale were certain styrene monomer assets and the Company’s 50 percent ownership interest in Americas Styrenics LLC, a nonconsolidated affiliate. The transaction also resulted in several long-term supply, service and purchase agreements between Dow and Styron.

Styron’s results of operations were not classified as discontinued operations, as the Company has continuing cash flows as a result of the supply, service and purchase agreements, and continues to hold an equity interest.

The following table presents the major classes of assets and liabilities divested by operating segment:

Post-closing adjustments were finalized in the fourth quarter of 2010. In 2010, the Company recognized a pretax gain of $27 million on the sale, net of post-closing adjustments of $24 million and including a net gain on the sale of two small, related joint ventures, working capital adjustments and additional costs to sell. The net gain was included in “Sundry income – net” and reflected in the following operating segments: Performance Materials ($20 million) and Performance Plastics ($7 million). The sale resulted in an after-tax loss of $56 million, primarily because goodwill related to the divestiture was not tax deductible.

On February 3, 2011, Styron repaid the $75 million long-term note receivable, plus interest.

Divestitures Required as a Condition to the Acquisition of Rohm and Haas

As a condition of the FTC’s approval of the April 1, 2009 acquisition of Rohm and Haas, the Company was required to divest a portion of its acrylic monomer business, a portion of its specialty latex business and its hollow sphere particle business. As a result, the Company recognized an impairment charge of $205 million related to these assets in the second quarter of 2009 restructuring charge (see Note C).

On July 31, 2009, the Company entered into a definitive agreement that included the sale of the portion of its acrylic monomer business and the portion of its specialty latex business. The sale was completed on January 25, 2010. Additional impairment charges of $8 million related to these assets were recognized in the first quarter of 2010. In the second quarter of 2010, additional severance costs of $1 million and the write-off of other assets of $5 million were recognized (see Note C).

The Company completed the sale of its hollow sphere particle business in the second quarter of 2010 and recognized additional costs associated with disposal activities of $7 million, related to contract termination fees (see Note C).

Divestiture of the Rohm and Haas Salt Business

On April 1, 2009, the Company announced the entry into a definitive agreement to sell the stock of Morton International, Inc. (“Morton”), the Salt business of Rohm and Haas, to K+S Aktiengesellschaft (“K+S”). On October 1, 2009, the Company completed the divestiture of its interest in Morton to K+S and received net proceeds of $1,576 million, with proceeds subject to customary post-closing adjustments. As a result, the Company recognized a pretax $37 million gain on the sale in the fourth quarter of 2009, included in “Sundry income – net,” and reflected in Corporate. One billion dollars in proceeds from this transaction were used to pay off the Term Loan Agreement used to fund the acquisition of Rohm and Haas (see Note P). The results of operations for the Salt business were reported in Corporate and were not material to the consolidated financial statements.

Divestiture of the Calcium Chloride Business

On June 30, 2009, the Company completed the sale of the Calcium Chloride business for net proceeds of $204 million and recognized a pretax gain of $162 million. The results of the Calcium Chloride business, including the second quarter of 2009 gain on the sale, are reflected as “Income from discontinued operations, net of income taxes” in the consolidated statements of income.

The following table presents the results of discontinued operations:

Divestiture of Investments in Nonconsolidated Affiliates

On September 1, 2009, the Company completed the sale of its ownership interest in Total Raffinaderij Nederland N.V. (“TRN”), a nonconsolidated affiliate, and related inventory to Total S.A. for $742 million. This sale resulted in a pretax net gain of $457 million, which consisted of a gain of $513 million reflected in “Sundry income – net” and a charge of $56 million related to the recognition of hedging losses which were recorded to “Cost of sales.” The gain impacted the Feedstocks and Energy segment.

On September 30, 2009 the Company completed the sale of its ownership interest in the OPTIMAL Group of Companies (“OPTIMAL”), nonconsolidated affiliates, to Petroliam Nasional Berhad for net proceeds of $660 million. This sale resulted in a pretax gain of $339 million included in “Sundry income – net,” and reflected in the operating segments as follows: $146 million in Performance Materials and $193 million in Feedstocks and Energy.

At December 31, 2010, the Company had $3,200 million of held-to-maturity securities (primarily Treasury Bills) classified as cash equivalents, as these securities had original maturities of three months or less. At December 31, 2009, the Company had no such securities. The Company’s investments in held-to-maturity securities are held at amortized cost, which approximates fair value. At December 31, 2010, the Company had investments in money market funds of $35 million classified as cash equivalents ($164 million at December 31, 2009).

The net unrealized gain recognized during 2010 on trading securities held at December 31, 2010 was $14 million ($7 million at December 31, 2009).

The following tables provide the fair value and gross unrealized losses of the Company’s investments that were deemed to be temporarily impaired at December 31, 2010 and 2009, aggregated by investment category and length of time that individual securities had been in a continuous unrealized loss position:

Portfolio managers regularly review the Company’s holdings to determine if any investments are other-than-temporarily impaired. The analysis includes reviewing the amount of the impairment, as well as the length of time it has been impaired. In addition, specific guidelines for each instrument type are followed to determine if an other-than-temporary impairment has occurred.

For debt securities, the credit rating of the issuer, current credit rating trends, the trends of the issuer’s overall sector, the ability of the issuer to pay expected cash flows and the length of time the security has been in a loss position are considered in determining whether unrealized losses represent an other-than-temporary impairment. The Company did not have any credit-related losses during 2010 or 2009.

For equity securities, the Company’s investments are primarily in Standard & Poor’s (“S&P”) 500 companies; however, the Company’s policies allow investments in companies outside of the S&P 500. The largest holdings are Exchange Traded Funds that represent the S&P 500 index or an S&P 500 sector or subset. The Company considers the evidence to support the recovery of the cost basis of a security including volatility of the stock, the length of time the security has been in a loss position, value and growth expectations, and overall market and sector fundamentals, as well as technical analysis, in determining whether unrealized losses represent an other-than-temporary impairment. In 2010, other-than-temporary impairment write-downs on investments still held by the Company were $5 million ($93 million in 2009).

The aggregate cost of the Company's cost method investments totaled $171 million at December 31, 2010 ($129 million at December 31, 2009). Due to the nature of these investments, the fair market value is not readily determinable. These investments are reviewed for impairment indicators. During 2010, the Company's impairment analysis identified indicators that resulted in a reduction in the cost basis of these investments of $16 million; the analysis resulted in a reduction of $10 million for the year ended December 31, 2009.

Risk Management

Dow’s business operations give rise to market risk exposure due to changes in interest rates, foreign currency exchange rates, commodity prices and other market factors such as equity prices. To manage such risks effectively, the Company enters into hedging transactions, pursuant to established guidelines and policies, which enable it to mitigate the adverse effects of financial market risk. Derivatives used for this purpose are designated as cash flow, fair value or net foreign investment hedges where appropriate. The guidance requires companies to recognize all derivative instruments as either assets or liabilities at fair value. A secondary objective is to add value by creating additional nonspecific exposures within established limits and policies; derivatives used for this purpose are not designated as hedges. The potential impact of creating such additional exposures is not material to the Company’s results.

The Company’s risk management program for interest rate, foreign currency and commodity risks is based on fundamental, mathematical and technical models that take into account the implicit cost of hedging. Risks created by derivative instruments and the mark-to-market valuations of positions are strictly monitored at all times, using value at risk and stress tests. Credit risk arising from these contracts is not significant because the Company minimizes counterparty concentration, deals primarily with major financial institutions of solid credit quality, and the majority of its hedging transactions mature in less than three months. In addition, the Company minimizes concentrations of credit risk through its global orientation in diverse businesses with a large number of diverse customers and suppliers. It is the Company’s policy not to have credit-risk-related contingent features in its derivative instruments. The Company does not anticipate losses from credit risk and the net cash requirements arising from counterparty risk associated with risk management activities are not expected to be material in 2011. No significant concentration of credit risk existed at December 31, 2010.

The Company reviews its overall financial strategies and the impacts from using derivatives in its risk management program with the Company’s Board of Directors and revises its strategies as market conditions dictate.

Interest Rate Risk Management

The Company enters into various interest rate contracts with the objective of lowering funding costs or altering interest rate exposures related to fixed and variable rate obligations. In these contracts, the Company agrees with other parties to exchange, at specified intervals, the difference between fixed and floating interest amounts calculated on an agreed-upon notional principal amount. At December 31, 2010, the Company had no open interest rate swaps.

Foreign Currency Risk Management

The Company’s global operations require active participation in foreign exchange markets. The Company enters into foreign exchange forward contracts and options, and cross-currency swaps to hedge various currency exposures or create desired exposures. Exposures primarily relate to assets, liabilities and bonds denominated in foreign currencies, as well as economic exposure, which is derived from the risk that currency fluctuations could affect the dollar value of future cash flows related to operating activities. The primary business objective of the activity is to optimize the U.S. dollar value of the Company’s assets, liabilities and future cash flows with respect to exchange rate fluctuations. Assets and liabilities denominated in the same foreign currency are netted, and only the net exposure is hedged. At December 31, 2010, the Company had forward contracts, options and cross-currency swaps to buy, sell or exchange foreign currencies. These contracts had various expiration dates, primarily in the first quarter of 2011.

Commodity Risk Management

The Company has exposure to the prices of commodities in its procurement of certain raw materials. The primary purpose of commodity hedging activities is to manage the price volatility associated with these forecasted inventory purchases. At December 31, 2010, the Company had futures contracts, options and swaps to buy, sell or exchange commodities. These agreements had various expiration dates primarily in 2011.

Accounting for Derivative Instruments and Hedging Activities

Cash Flow Hedges

For derivatives that are designated and qualify as cash flow hedging instruments, the effective portion of the gain or loss on the derivative is recorded in “Accumulated other comprehensive income (loss)” (“AOCI”); it is reclassified to “Cost of sales” in the same period or periods that the hedged transaction affects income. The unrealized amounts in AOCI fluctuate based on changes in the fair value of open contracts at the end of each reporting period. The Company anticipates volatility in AOCI and net income from its cash flow hedges. The amount of volatility varies with the level of derivative activities and market conditions during any period. Gains and losses on the derivative representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness are recognized in current period income.

The net loss from previously terminated interest rate cash flow hedges included in AOCI at December 31, 2010 was $2 million after tax ($2 million after tax at December 31, 2009). During 2010, 2009 and 2008, there was no material impact on the consolidated financial statements due to interest rate hedge ineffectiveness. The Company had no open interest rate derivatives at December 31, 2010 (notional U.S. dollar equivalent of $30 million at December 31, 2009).

Current open foreign currency forward contracts hedge the currency risk of forecasted feedstock purchase transactions until April 2011. The effective portion of the mark-to-market effects of the foreign currency forward contracts is recorded in AOCI; it is reclassified to income in the same period or periods that the underlying feedstock purchase affects income. The net loss from the foreign currency hedges included in AOCI at December 31, 2010 was $4 million after tax (net loss of $5 million after tax at December 31, 2009). During 2010, 2009 and 2008, there was no material impact on the consolidated financial statements due to foreign currency hedge ineffectiveness. At December 31, 2010, the Company had open forward contracts with various expiration dates to buy, sell or exchange foreign currencies with a notional U.S. dollar equivalent of $827 million ($645 million at December 31, 2009).

Commodity swaps, futures and option contracts with maturities of not more than 36 months are utilized and designated as cash flow hedges of forecasted commodity purchases. Current open contracts hedge forecasted transactions until December 2011. The effective portion of the mark-to-market effect of the cash flow hedge instrument is recorded in AOCI; it is reclassified to income in the same period or periods that the underlying commodity purchase affects income. Due to the September 1, 2009 sale of TRN, the Company recognized a pretax loss of $56 million for cash flow hedges of forecasted purchases that will not occur as a result of the sale (see Note E). The net gain from commodity hedges included in AOCI at December 31, 2010 was $3 million after tax (zero at December 31, 2009). During 2010, 2009 and 2008, there was no material impact on the consolidated financial statements due to commodity hedge ineffectiveness. At December 31, 2010 and 2009, the Company had the following aggregate notionals of outstanding commodity forward contracts to hedge forecasted purchases:

Commodity	2010	2009	Notional Volume Unit
Crude Oil	0.1	0.7	million barrels
Ethane	1.6	—	million barrels
Naphtha	—	50	kilotons
Natural Gas	2.7	2.0	million million British thermal units

Fair Value Hedges

For derivative instruments that are designated and qualify as fair value hedges, the gain or loss on the derivative as well as the offsetting loss or gain on the hedged item attributable to the hedged risk are recognized in current period income and reflected as “Interest expense and amortization of debt discount” in the consolidated statements of income. The short-cut method is used when the criteria are met. The Company had no open interest rate swaps designated as fair value hedges of underlying fixed rate debt obligations at December 31, 2010 and 2009.

Net Foreign Investment Hedges

For derivative instruments that are designated and qualify as net foreign investment hedges, the effective portion of the gain or loss on the derivative is included in “Cumulative Translation Adjustments” in AOCI. The results of hedges of the Company’s net investment in foreign operations included in “Cumulative Translation Adjustments” in AOCI was a net gain of $70 million after tax at December 31, 2010 (net loss of $56 million after tax at December 31, 2009). During 2010, 2009 and 2008 there was no material impact on the consolidated financial statements due to hedge ineffectiveness. At December 31, 2010 and 2009, the Company had no open forward contracts or outstanding options to buy, sell or exchange foreign currencies. At December 31, 2010, the Company had outstanding foreign-currency denominated debt designated as a hedge of net foreign investment of $1,250 million ($1,879 million at December 31, 2009).

Other Derivative Instruments

The Company utilizes futures, options and swap instruments that are effective as economic hedges of commodity price exposures, but do not meet the hedge accounting criteria in the accounting guidance for derivatives and hedging. At December 31, 2010 and 2009, the Company had the following aggregate notionals of outstanding commodity contracts:

Commodity	2010	2009	Notional Volume Unit
Ethane	3.8	0.9	million barrels
Natural Gas	12.0	2.8	million million British thermal units

The Company also uses foreign exchange forward contracts, options, and cross-currency swaps that are not designated as hedging instruments primarily to manage foreign currency and interest rate exposure. The Company had open foreign exchange contracts with various expiration dates to buy, sell or exchange foreign currencies and a notional U.S. dollar equivalent of $13,944 million at December 31, 2010 ($15,312 million at December 31, 2009).

REDEEMABLE PREFERRED STOCKS

Cumulative Perpetual Preferred Stock, Series B

With the April 1, 2009 acquisition of Rohm and Haas, certain trusts established by members of the Haas family (the “Haas Trusts”) and Paulson & Co. Inc. (“Paulson”) purchased from the Company Cumulative Perpetual Preferred Stock, Series B (“preferred series B”) in the amount of 2.5 million shares (Haas Trusts – 1.5 million shares; Paulson – 1.0 million shares) for an aggregate price of $2.5 billion (Haas Trusts – $1.5 billion; Paulson – $1.0 billion). Under the terms of the preferred series B, the holders were entitled to cumulative dividends at a rate of 7 percent per annum in cash and 8 percent per annum either in cash or as an increase in the liquidation preference of the preferred series B, at the Company’s option.

In May 2009, the Company entered into a purchase agreement with the Haas Trusts and Paulson, whereby the Haas Trusts and Paulson agreed to sell to the Company their shares of the preferred series B in consideration for shares of the Company’s common stock and/or notes, at the discretion of the Company. Pursuant to the purchase agreement, the Company issued 83.3 million shares of its common stock to the Haas Trusts and Paulson in consideration for the purchase of 1.2 million shares of preferred series B held by the Haas Trusts and Paulson. In a separate transaction as part of a $6 billion offering of senior notes, the Company issued $1.35 billion aggregate principal amount of 8.55 percent notes due 2019 to the Haas Trusts and Paulson in consideration for the purchase of the remaining 1.3 million shares of preferred series B at par plus accrued dividends. Upon the consummation of these transactions, all shares of preferred series B were retired. For additional information concerning the common stock and debt issuances, see Notes P and X.

Cumulative Convertible Perpetual Preferred Stock, Series C

With the April 1, 2009 acquisition of Rohm and Haas, the Haas Trusts invested $500 million in Cumulative Convertible Perpetual Preferred Stock, Series C (“preferred series C”). Under the terms of the preferred series C, prior to June 8, 2009, the holders were entitled to cumulative dividends at a rate of 7 percent per annum in cash and 8 percent per annum either in cash or as an increase in the liquidation preference of the preferred series C, at the Company’s option. On and after June 8, 2009, the Company would have been required to pay cumulative dividends of 12 percent per annum in cash.

The preferred series C shares would automatically convert to common stock on the date immediately following the ten full trading days commencing on the date on which there was an effective shelf registration statement relating to the common stock underlying the preferred series C, if such registration statement was effective prior to June 8, 2009. On May 26, 2009, the Company entered into an underwriting agreement and filed the corresponding shelf registration statement to effect the conversion of preferred series C into the Company’s common stock in accordance with the terms of the preferred series C. Under the terms of the preferred series C, the shares of preferred series C would convert into shares of the Company’s common stock at a conversion price per share of common stock based upon 95 percent of the average of the common stock volume-weighted average price for the ten trading days preceding the conversion. After ten full trading days and upon the automatic conversion of the preferred series C, the Company issued 31.0 million shares of the Company’s common stock to the Haas Trusts on June 9, 2009, and all shares of preferred series C were retired (see Note X).

ACQUISITIONS

Acquisition of Rohm and Haas

On April 1, 2009, the Company completed the acquisition of Rohm and Haas. Pursuant to the July 10, 2008 Agreement and Plan of Merger (the “Merger Agreement”), Ramses Acquisition Corp., a direct wholly owned subsidiary of the Company, merged with and into Rohm and Haas (the “Merger”), with Rohm and Haas continuing as the surviving corporation and becoming a direct wholly owned subsidiary of the Company.

The Company pursued the acquisition of Rohm and Haas to make the Company a leading specialty chemicals and advanced materials company, combining the two organizations’ best-in-class technologies, broad geographic reach and strong industry channels to create a business portfolio with significant growth opportunities.

Pursuant to the terms and conditions of the Merger Agreement, each outstanding share of Rohm and Haas common stock was converted into the right to receive cash of $78 per share, plus additional cash consideration of $0.97 per share. The additional cash consideration represented 8 percent per annum on the $78 per share consideration from January 10, 2009 to the closing of the Merger, less dividends declared by Rohm and Haas with a dividend record date between January 10, 2009 and the closing of the Merger. All options to purchase shares of common stock of Rohm and Haas granted under the Rohm and Haas stock option plans and all other Rohm and Haas equity-based compensation awards, whether vested or unvested as of April 1, 2009, became fully vested and converted into the right to receive cash of $78.97 per share, less any applicable exercise price. Total cash consideration paid to Rohm and Haas shareholders was $15,681 million. As part of the purchase price, $552 million in cash was paid to the Rohm and Haas Company Employee Stock Ownership Plan (“Rohm and Haas ESOP”) on April 1, 2009 for 7.0 million shares of Rohm and Haas common stock held by the Rohm and Haas ESOP.

As a condition of the FTC’s approval of the Merger, the Company was required to divest a portion of its acrylic monomer business, a portion of its specialty latex business and its hollow sphere particle business. The Company completed the sale of these businesses in 2010 (see Note E). Total net sales and cost of sales for these businesses amounted to approximately one percent of the Company’s 2008 net sales and cost of sales.

The following table provides net sales and results of operations from the Rohm and Haas acquired businesses included in the Company’s 2009 results since the April 1, 2009 acquisition. Included in the results from Rohm and Haas was $257 million of restructuring charges (see Note C), a one-time increase in cost of sales of $209 million related to the fair value step-up of inventories acquired from Rohm and Haas and sold in the second quarter of 2009 and a pretax loss of $56 million on the early extinguishment of debt.

The following table provides pro forma net sales and results of operations for the years ended December 31, 2009 and December 31, 2008, as if Rohm and Haas had been acquired on January 1 of each year. The unaudited pro forma results reflect certain adjustments related to the acquisition, such as increased depreciation and amortization expense on assets acquired from Rohm and Haas resulting from the fair valuation of assets acquired and the impact of acquisition financing in place at December 31, 2009. The pro forma results do not include any anticipated cost synergies or other effects of the planned integration of Rohm and Haas. Accordingly, such pro forma amounts are not necessarily indicative of the results that actually would have occurred had the acquisition been completed on the dates indicated, nor are they indicative of the future operating results of the combined company.

The following table summarizes the fair values of the assets acquired and liabilities assumed from Rohm and Haas on April 1, 2009. During the measurement period, which ended on March 31, 2010, net adjustments of $145 million were made to the fair values of the assets acquired and liabilities assumed with a corresponding adjustment to goodwill. These adjustments are summarized in the table presented below. The balance sheet at December 31, 2009 has been retrospectively adjusted to reflect these adjustments as required by the accounting guidance for business combinations. No further adjustments have been made to the acquisition-date fair values of assets acquired and liabilities assumed since the end of the measurement period.

The fair value of receivables acquired from Rohm and Haas on April 1, 2009 (net of the Salt business) was $1,001 million, with gross contractual amounts receivable of $1,048 million. Liabilities assumed from Rohm and Haas on April 1, 2009 included certain contingent environmental liabilities valued at $159 million and a liability of $185 million related to Rohm and Haas Pension Plan matters (see Note N), which were valued in accordance with the accounting guidance for contingencies. Operating loss carryforwards of $2,189 million were acquired from Rohm and Haas on April 1, 2009, $137 million of which were subject to expiration in 2009 through 2013.

The following table summarizes the major classes of assets and liabilities underlying the deferred tax liabilities resulting from the acquisition of Rohm and Haas:

Deferred Tax Liabilities Assumed on April 1, 2009 In millions	As Adjusted
Intangible assets	$	1,754
Property	526
Long-term debt	191
Inventory	80
Other accruals and reserves	324
Total Deferred Tax Liabilities	$	2,875

The acquisition resulted in the recognition of $9,707 million of goodwill, which is not deductible for tax purposes. See Note I for further information on goodwill, including the allocation by segment.

Goodwill largely consists of expected synergies resulting from the acquisition. Key areas of cost savings include increased purchasing power for raw materials; manufacturing and supply chain work process improvements; and the elimination of redundant corporate overhead for shared services and governance. The Company also anticipates that the transaction will produce significant growth synergies through the application of each company’s innovative technologies and through the combined businesses’ broader product portfolio in key industry segments with strong global growth rates.

Financing for the Rohm and Haas Acquisition

Financing for the acquisition of Rohm and Haas included debt and equity financing (see Notes P, W and X).

Rohm and Haas Acquisition and Integration Related Expenses

During 2010, pretax charges totaling $143 million were recorded for integration expenses related to the April 1, 2009 acquisition of Rohm and Haas. During 2009, pretax charges totaling $166 million ($49 million in 2008) were recorded for legal expenses and other transaction and integration costs related to the acquisition. These charges, which were expensed in accordance with the accounting guidance for business combinations, were recorded in “Acquisition and integration related expenses” and reflected in Corporate. An additional $60 million of acquisition-related retention expenses were incurred during 2009 and recorded in “Cost of sales,” “Research and development expenses,” and “Selling, general and administrative expenses” and reflected in Corporate.

Purchased In-Process Research and Development

Purchased in-process research and development (“IPR&D”) represents the value assigned to acquired research and development projects that, as of the date of the acquisition, had not established technological feasibility and had no alternative future use. Prior to January 1, 2009, amounts assigned to IPR&D meeting these criteria were charged to expense as part of the allocation of the purchase price of the business combination. With the adoption of ASC Topic 805, “Business Combinations,” on January 1, 2009, IPR&D acquired in a business combination is capitalized and tested for impairment annually.

The Company recorded pretax charges totaling $7 million in 2009 for IPR&D projects associated with the purchase of technology that was not part of a business combination. The Company recorded pretax charges totaling $44 million in 2008 for IPR&D projects associated with several acquisitions. The estimated values assigned to the IPR&D projects were determined primarily based on a discounted cash flow model and are shown below:

In-Process Research and Development Projects Acquired In millions	Date of Acquisition	Estimated   Value Assigned   to IPR&D
2009
Lithium ion battery technology purchase	October 30, 2009	$	7
2008
Germplasm from Triumph Seed Co., Inc.	February 29, 2008	$	4
Germplasm from Dairyland Seed Co., Inc. and Bio-Plant Research Ltd.	August 29, 2008	23
Germplasm from Südwestsaat GbR	December 16, 2008	17
Total 2008 IPR&D		$	44

The IPR&D charges outlined above are shown as “Purchased in-process research and development charges” in the consolidated statements of income. The 2009 IPR&D charges related to a technology purchase for projects within the Ventures business, impacting Corporate. The 2008 IPR&D charges were related to projects within the Agricultural Sciences segment.

The following transactions were entered into for the purpose of providing diversified sources of funds to the Company.

In July 1999, Tornado Finance V.O.F., a former consolidated foreign subsidiary of the Company, issued $500 million of preferred securities in the form of preferred partnership units. The units provided a distribution of 7.965 percent, could be redeemed in 2009 or thereafter, and could be called at any time by the subsidiary. On June 4, 2009, the preferred partner notified Tornado Finance V.O.F. that the preferred partnership units would be redeemed in full on July 9, 2009, as permitted by the terms of the partnership agreement. On July 9, 2009, the preferred partnership units and accrued dividends were redeemed for a total of $520 million. Upon redemption, Tornado Finance V.O.F. was dissolved. The distributions were included in “Net income attributable to noncontrolling interests” in the consolidated statements of income.

In September 2001, Hobbes Capital S.A. (“Hobbes”), a former consolidated foreign subsidiary of the Company, issued $500 million of preferred securities in the form of equity certificates. The certificates provided a floating rate of return (which could be reinvested) based on LIBOR. During the third quarter of 2008, the other partner of Hobbes redeemed its $674 million ownership in Hobbes. The minority ownership was redeemed in a non-cash transaction in exchange for a three-year note payable with a floating rate based on LIBOR, which was repaid in September 2009. Prior to redemption, the preferred return was included in “Net income attributable to noncontrolling interests” in the consolidated statements of income.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Accounting Policies [Abstract]

Significant Accounting Policies [Text Block]

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation and Basis of Presentation

The accompanying consolidated financial statements of The Dow Chemical Company and its subsidiaries (“Dow” or the “Company”) were prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and include the assets, liabilities, revenues and expenses of all majority-owned subsidiaries over which the Company exercises control and, when applicable, entities for which the Company has a controlling financial interest or is the primary beneficiary. Intercompany transactions and balances are eliminated in consolidation. Investments in nonconsolidated affiliates (20-50 percent owned companies, joint ventures and partnerships) are accounted for using the equity method.

Certain changes to prior year balance sheet amounts have been made in accordance with the accounting guidance for business combinations to reflect adjustments made during the measurement period to provisional amounts recorded for assets acquired and liabilities assumed from Rohm and Haas Company (“Rohm and Haas”) on April 1, 2009. Certain changes have been made to geographic area information for prior years to reflect changes made in the first quarter of 2010. Certain changes have been made to operating segment information to reflect changes made in the third quarter of 2011 related to changes in the Company’s organization. A change to current year balance sheet amounts has been made to properly classify the current portion of "Deferred charges and other assets" of $349 million to "Other current assets."

Use of Estimates in Financial Statement Preparation

The preparation of financial statements in accordance with U.S. GAAP requires the use of estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. The Company’s consolidated financial statements include amounts that are based on management’s best estimates and judgments. Actual results could differ from those estimates.

Foreign Currency Translation

The local currency has been primarily used as the functional currency throughout the world. Translation gains and losses of those operations that use local currency as the functional currency are included in the consolidated balance sheets in “Accumulated other comprehensive income (loss)” (“AOCI”). Where the U.S. dollar is used as the functional currency, foreign currency gains and losses are reflected in income.

Environmental Matters

Accruals for environmental matters are recorded when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated based on current law and existing technologies. These accruals are adjusted periodically as assessment and remediation efforts progress or as additional technical or legal information becomes available. Accruals for environmental liabilities are included in the consolidated balance sheets in “Accrued and other current liabilities” and “Other noncurrent obligations” at undiscounted amounts. Accruals for related insurance or other third-party recoveries for environmental liabilities are recorded when it is probable that a recovery will be realized and are included in the consolidated balance sheets as “Accounts and notes receivable - Other.”

Environmental costs are capitalized if the costs extend the life of the property, increase its capacity, and/or mitigate or prevent contamination from future operations. Environmental costs are also capitalized in recognition of legal asset retirement obligations resulting from the acquisition, construction and/or normal operation of a long-lived asset. Costs related to environmental contamination treatment and cleanup are charged to expense. Estimated future incremental operations, maintenance and management costs directly related to remediation are accrued when such costs are probable and reasonably estimable.

Cash and Cash Equivalents

Cash and cash equivalents include time deposits and readily marketable securities with original maturities of three months or less.

Financial Instruments

The Company calculates the fair value of financial instruments using quoted market prices whenever available. When quoted market prices are not available for various types of financial instruments (such as forwards, options and swaps), the Company uses standard pricing models with market-based inputs that take into account the present value of estimated future cash flows.

The Company utilizes derivatives to manage exposures to currency exchange rates, commodity prices and interest rate risk. The fair values of all derivatives are recognized as assets or liabilities at the balance sheet date. Changes in the fair value of these instruments are reported in income or AOCI, depending on the use of the derivative and whether it qualifies for hedge accounting treatment.

Gains and losses on derivatives that are designated and qualify as cash flow hedging instruments are recorded in AOCI, to the extent the hedges are effective, until the underlying transactions are recognized in income. To the extent effective, gains and losses on derivative and nonderivative instruments used as hedges of the Company’s net investment in foreign operations are recorded in AOCI as part of the cumulative translation adjustment. The ineffective portions of cash flow hedges and hedges of net investment in foreign operations, if any, are recognized in income immediately.

Gains and losses on derivatives designated and qualifying as fair value hedging instruments, as well as the offsetting losses and gains on the hedged items, are reported in income in the same accounting period. Derivatives not designated as hedging instruments are marked-to-market at the end of each accounting period with the results included in income.

Inventories

Inventories are stated at the lower of cost or market. The method of determining cost for each subsidiary varies among last-in, first-out (“LIFO”); first-in, first-out (“FIFO”); and average cost, and is used consistently from year to year.

Property

Land, buildings and equipment, including property under capital lease agreements, are carried at cost less accumulated depreciation. Depreciation is based on the estimated service lives of depreciable assets and is calculated using the straight-line method, unless the asset was capitalized before 1997 when the declining balance method was used. Fully depreciated assets are retained in property and accumulated depreciation accounts until they are removed from service. In the case of disposals, assets and related accumulated depreciation are removed from the accounts, and the net amounts, less proceeds from disposal, are included in income.

Impairment and Disposal of Long-Lived Assets

The Company evaluates long-lived assets and certain identifiable intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. When undiscounted future cash flows are not expected to be sufficient to recover an asset’s carrying amount, the asset is written down to its fair value based on bids received from third parties or a discounted cash flow analysis based on market participant assumptions.

Long-lived assets to be disposed of by sale are classified as held for sale and are reported at the lower of carrying amount or fair value less cost to sell, and depreciation is ceased. Long-lived assets to be disposed of other than by sale are classified as held and used until they are disposed of and are reported at the lower of carrying amount or fair value, and depreciation is recognized over the remaining useful life of the assets.

Goodwill and Other Intangible Assets

The Company records goodwill when the purchase price of a business acquisition exceeds the estimated fair value of net identified tangible and intangible assets acquired. Goodwill is tested for impairment at the reporting unit level annually, or more frequently when events or changes in circumstances indicate that the fair value of a reporting unit has more likely than not declined below its carrying value. The Company primarily utilizes a discounted cash flow methodology to calculate the fair value of its reporting units.

Finite-lived intangible assets such as purchased customer lists, licenses, intellectual property, patents, trademarks and software, are amortized over their estimated useful lives, generally on a straight-line basis for periods ranging primarily from three to twenty years. Finite-lived intangible assets are reviewed for impairment or obsolescence annually, or more frequently when events or changes in circumstances indicate that the carrying amount of an intangible asset may not be recoverable. If impaired, intangible assets are written down to fair value based on discounted cash flows.

Asset Retirement Obligations

The Company records asset retirement obligations as incurred and reasonably estimable, including obligations for which the timing and/or method of settlement are conditional on a future event that may or may not be within the control of the Company. The fair values of obligations are recorded as liabilities on a discounted basis and are accreted over time for the change in present value. Costs associated with the liabilities are capitalized and amortized over the estimated remaining useful life of the asset, generally for periods of 10 years or less.

Investments

Investments in debt and marketable equity securities (including warrants), primarily held by the Company’s insurance operations, are classified as trading, available-for-sale or held-to-maturity. Investments classified as trading are reported at fair value with unrealized gains and losses included in income. Those classified as available-for-sale are reported at fair value with unrealized gains and losses recorded in AOCI. Those classified as held-to-maturity are recorded at amortized cost. The cost of investments sold is determined by specific identification. The Company routinely reviews available-for-sale and held-to-maturity securities for other-than-temporary declines in fair value below the cost basis, and when events or changes in circumstances indicate the carrying value of an asset may not be recoverable, the security is written down to fair value, establishing a new cost basis.

Revenue

Sales are recognized when the revenue is realized or realizable, and the earnings process is complete. Approximately 99 percent of the Company’s sales in 2010 related to sales of product. The remaining 1 percent in 2010 related to the Company’s service offerings, insurance operations, and licensing of patents and technology. Revenue for product sales is recognized as risk and title to the product transfer to the customer, which usually occurs at the time shipment is made. As such, title to the product passes when the product is delivered to the freight carrier. Dow’s standard terms of delivery are included in its contracts of sale, order confirmation documents and invoices. Freight costs and any directly related costs of transporting finished product to customers are recorded as “Cost of sales.”

Revenue related to the Company’s insurance operations includes third-party insurance premiums, which are earned over the terms of the related insurance policies and reinsurance contracts. Revenue related to the initial licensing of patents and technology is recognized when earned; revenue related to running royalties is recognized according to licensee production levels.

Legal Costs

The Company expenses legal costs, including those legal costs expected to be incurred in connection with a loss contingency, as incurred.

Severance Costs

The Company routinely reviews its operations around the world in an effort to ensure competitiveness across its businesses and geographic areas. When the reviews result in a workforce reduction related to the shutdown of facilities or other optimization activities, severance benefits are provided to employees primarily under Dow’s ongoing benefit arrangements. These severance costs are accrued under the guidance of the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification™ (“ASC”) Topic 712, “Compensation – Nonretirement Postemployment Benefits,” once management commits to a plan of termination including the number of employees to be terminated, their job classifications or functions, their locations and the expected completion date.

Income Taxes

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 of temporary differences between the carrying amounts and tax bases of assets and liabilities using enacted rates. The effect of a change in tax rates on deferred tax assets is recognized in income in the period that includes the enactment date.

Annual tax provisions include amounts considered sufficient to pay assessments that may result from examinations of prior year tax returns; however, the amount ultimately paid upon resolution of issues raised may differ from the amounts accrued.

The Company recognizes the financial statement effects of an uncertain income tax position when it is more likely than not, based on the technical merits, that the position will be sustained upon examination. The Company accrues for other tax contingencies when it is probable that a liability to a taxing authority has been incurred and the amount of the contingency can be reasonably estimated. The current portion of uncertain income tax positions is included in “Income taxes payable” and the long-term portion is included in “Other noncurrent obligations” in the consolidated balance sheets.

Provision is made for taxes on undistributed earnings of foreign subsidiaries and related companies to the extent that such earnings are not deemed to be permanently invested.

Earnings per Common Share

The calculation of earnings per common share is based on the weighted-average number of the Company’s common shares outstanding for the applicable period. The calculation of diluted earnings per common share reflects the effect of all potential dilutive common shares that were outstanding during the respective periods, unless the effect of doing so is antidilutive.

VARIABLE INTEREST ENTITIES

VARIABLE INTEREST ENTITIES [Abstract]

Variable Interest Entities Disclosure [Text Block]

NOTE S – VARIABLE INTEREST ENTITIES

On January 1, 2010, the Company adopted ASU 2009-17, “Consolidations (Topic 810): Improvements to Financial Reporting by Enterprises Involved with Variable Interest Entities.” ASU 2009-17 amends the consolidation guidance applicable to variable interest entities (“VIEs”) and requires additional disclosures concerning an enterprise’s continuing involvement with VIEs. The Company evaluated the impact of this guidance and determined that the adoption resulted in the January 1, 2010 consolidation of two additional joint ventures, an owner trust and an entity that is used to monetize accounts receivable. The Company elected prospective application of this guidance at adoption.

The following table summarizes the carrying amount of the assets and liabilities of the two additional joint ventures and the owner trust entity included in the Company’s consolidated balance sheet at January 1, 2010.

Assets and Liabilities of Newly Consolidated VIEs Included in the  Consolidated Balance Sheet In millions	Jan 1, 2010
Current assets	$	37
Property	209
Other noncurrent assets	3
Total assets	$	249
Current liabilities	$	76
Long-term debt	346
Total liabilities	$	422

The carrying amounts of assets and liabilities pertaining to the entity used to monetize accounts receivable, included in the Company’s consolidated balance sheet at January 1, 2010, were current assets of $817 million (including $436 million of restricted cash) and current liabilities of $589 million.

Consolidated Variable Interest Entities

The Company holds a variable interest in five joint ventures for which the Company is the primary beneficiary. Three of the joint ventures are development stage enterprises, which will produce propylene oxide and hydrogen peroxide and provide terminal services in Thailand. The Company’s variable interest in these joint ventures relates to cost-plus arrangements between the joint venture and the Company, involving the majority of the output on take-or-pay terms and ensuring a guaranteed return to the joint ventures.

Another joint venture will construct, own and operate a membrane chlor-alkali facility to be located at the Company’s Freeport, Texas integrated manufacturing complex. The Company’s variable interests in this joint venture relate to equity options between the partners and a cost-plus off-take arrangement between the joint venture and the Company, involving proportional purchase commitments on take-or-pay terms and ensuring a guaranteed return to the joint venture. The Company will provide the joint venture with operation and maintenance services, utilities and raw materials; market the joint venture’s co-products; and toll convert the other partner’s proportional purchase commitments into ethylene dichloride. The joint venture is expected to begin operations in mid-2013.

The fifth joint venture was acquired through the acquisition of Rohm and Haas on April 1, 2009. This joint venture manufactures products in Japan for the semiconductor industry. Each joint venture partner holds several equivalent variable interests, with the exception of a royalty agreement held exclusively between the joint venture and the Company. In addition, the entire output of the joint venture is sold to the Company for resale to third-party customers.

The Company also holds a variable interest in an owner trust, for which the Company is the primary beneficiary. The owner trust leases an ethylene facility in The Netherlands to the Company, whereby substantially all of the rights and obligations of ownership are transferred to the Company. The Company’s variable interest in the owner trust relates to a residual value guarantee provided to the owner trust. Upon expiration of the lease, which matures in 2014, the Company may purchase the facility for an amount based on a fair market value determination. At December 31, 2010, the Company had provided to the owner trust a residual value guarantee of $363 million, which represents the Company’s maximum exposure to loss under the lease.

As the primary beneficiary of these VIEs, the entities’ assets, liabilities and results of operations are included in the Company’s consolidated financial statements. The other equity holders’ interests are reflected in “Net income attributable to noncontrolling interests” in the consolidated statements of income and “Noncontrolling interests” in the consolidated balance sheets. The following table summarizes the carrying amounts of the entities’ assets and liabilities included in the Company’s consolidated balance sheets at December 31, 2010 and December 31, 2009:

Assets and Liabilities of Consolidated VIEs  In millions	Dec 31, 2010		Dec 31, 2009
Current assets (restricted 2010: $228)	$	228	$	102

The Company holds a variable interest in an entity created in June 2010 to monetize accounts receivable of select European entities. The Company is the primary beneficiary of this entity as a result of holding subordinated notes while maintaining servicing responsibilities for the accounts receivable. The carrying amounts of assets and liabilities pertaining to this entity, included in the Company’s consolidated balance sheet at December 31, 2010, were current assets of $158 million (zero restricted) and current liabilities of $1 million ($1 million nonrecourse). Prior to the creation of this entity, the Company held a variable interest in another entity that was also used to monetize accounts receivable originated by several European subsidiaries. That arrangement was terminated in June 2010. No gain or loss was recognized as a result of terminating the arrangement.

Amounts presented in the consolidated balance sheets and the table above as restricted assets or nonrecourse obligations relating to consolidated VIEs at December 31, 2010 are adjusted for intercompany eliminations, parental guarantees and residual value guarantees.

In September 2001, Hobbes Capital S.A. (“Hobbes”), a former consolidated foreign subsidiary of the Company, issued $500 million of preferred securities in the form of equity certificates. The certificates provided a floating rate of return (which could be reinvested) based on LIBOR. Under the accounting guidance for consolidation, Hobbes was a VIE and the Company was the primary beneficiary. During the third quarter of 2008, the other partner of Hobbes redeemed its $674 million ownership in Hobbes. The minority ownership was redeemed in a non-cash transaction in exchange for a three-year note payable with a floating rate based on LIBOR, which was repaid in September 2009. Prior to redemption, the preferred return was included in “Net income attributable to noncontrolling interests” in the consolidated statements of income.

Nonconsolidated Variable Interest Entity

The Company holds a variable interest in a joint venture accounted for under the equity method of accounting, acquired through the acquisition of Rohm and Haas on April 1, 2009. The joint venture manufactures crude acrylic acid in the United States and Germany on behalf of the Company and the other joint venture partner. The variable interest relates to a cost-plus arrangement between the joint venture and each joint venture partner. The Company is not the primary beneficiary, as a majority of the joint venture’s output is sold to the other joint venture partner, and therefore the entity is not consolidated. At December 31, 2010, the Company’s investment in the joint venture was $144 million, classified as “Investment in nonconsolidated affiliates” in the consolidated balance sheets, representing the Company’s maximum exposure to loss.

Stockholders' Equity Note [Abstract]

STOCKHOLDERS' EQUITY

STOCKHOLDERS’ EQUITY

Cumulative Convertible Perpetual Preferred Stock, Series A

Equity securities in the form of Cumulative Convertible Perpetual Preferred Stock, Series A (“preferred series A”) were issued on April 1, 2009 to Berkshire Hathaway Inc. in the amount of $3 billion (3 million shares) and the Kuwait Investment Authority in the amount of $1 billion (1 million shares). The Company will pay cumulative dividends on preferred series A at a rate of 8.5 percent per annum in either cash, shares of common stock, or any combination thereof, at the option of the Company. Dividends may be deferred indefinitely, at the Company’s option. If deferred, common stock dividends must also be deferred. Any past due and unpaid dividends will accrue additional dividends at a rate of 10 percent per annum, compounded quarterly. If dividends are deferred for any six quarters, the preferred series A shareholders may elect two directors to the Company’s Board of Directors until all past due dividends are paid. Ongoing dividends related to preferred series A are $85 million per quarter; no dividends had been deferred at December 31, 2010.

Shareholders of preferred series A may convert all or any portion of their shares, at their option, at any time, into shares of the Company’s common stock at an initial conversion rate of 24.2010 shares of common stock for each share of preferred series A. Under certain circumstances, the Company will be required to adjust the conversion rate. On or after the fifth anniversary of the issuance date, if the common stock price exceeds $53.72 per share for any 20 trading days in a consecutive 30-day window, the Company may, at its option, at any time, in whole or in part, convert preferred series A into common stock at the then applicable conversion rate. Upon conversion, accrued and unpaid dividends will be payable, at the option of the Company, in either cash, shares of common stock, or any combination thereof.

Common Stock

On May 6, 2009, the Company launched a public offering of 150.0 million shares of its common stock at a price of $15.00 per share. Included in the 150.0 million shares offered to the public were 83.3 million shares issued to the Haas Trusts and Paulson in consideration for shares of preferred series B held by the Haas Trusts and Paulson (see Note W). Gross proceeds were $2,250 million, of which the Company’s net proceeds (after underwriting discounts and commissions) were $966 million for the sale of the Company’s 66.7 million shares.

On May 26, 2009, the Company entered into an underwriting agreement and filed the corresponding shelf registration statement to effect the conversion of the preferred series C into shares of the Company’s common stock (see Note W). On June 9, 2009, following the end of the sale period and determination of the share conversion amount, the Company issued 31.0 million shares to the Haas Trusts.

The Company issues common stock shares for purchases under the Employees’ Stock Purchase Plan (“ESPP”) out of treasury stock or as new common stock shares. The number of new common stock shares issued to employees under the Company’s ESPP was 10.0 million in 2010. No new common shares were issued to ESPP participants in 2009 or 2008, as all share issuances were satisfied from treasury stock.

Retained Earnings

There are no significant restrictions limiting the Company’s ability to pay dividends.

Undistributed earnings of nonconsolidated affiliates included in retained earnings were $2,264 million at December 31, 2010 and $1,826 million at December 31, 2009.

Employee Stock Ownership Plan

The Company has the Dow Employee Stock Ownership Plan (the “ESOP”), which is an integral part of The Dow Chemical Company Employees’ Savings Plan (the “Plan”). A significant majority of full-time employees in the United States are eligible to participate in the Plan. The Company uses the ESOP to provide the Company’s matching contribution in the form of the Company’s stock to Plan participants.

In connection with the acquisition of Rohm and Haas (see Note D), $552 million in cash was paid to the Rohm and Haas Company Employee Stock Ownership Plan (the “Rohm and Haas ESOP”) for 7.0 million shares of Rohm and Haas common stock held by the Rohm and Haas ESOP on April 1, 2009. On the date of the acquisition, the Rohm and Haas ESOP was merged into the Plan, and the Company assumed the $78 million balance of debt at 9.8 percent interest with final maturity in 2020 that was used to finance share purchases by the Rohm and Haas ESOP in 1990. The outstanding balance of the debt was $64 million at December 31, 2010.

On May 11, 2009, the Company sold 36.7 million shares of common stock (from treasury stock) to the ESOP at a price of $15.0561 per share for a total of $553 million. The treasury stock was carried at an aggregate historical cost of $1,529 million.

Dividends on unallocated shares held by the ESOP are used by the ESOP to make debt service payments. Dividends on allocated shares are used by the ESOP to make debt service payments to the extent needed; otherwise, they are paid to the Plan participants. Shares are released for allocation to participants based on the ratio of the current year’s debt service to the sum of the principal and interest payments over the life of the loan. The shares are allocated to Plan participants in accordance with the terms of the Plan.

Compensation expense for allocated shares is recorded at the fair value of the shares on the date of allocation. ESOP shares that have not been released or committed to be released are not considered outstanding for purposes of computing basic and diluted earnings per share.

Compensation expense for ESOP shares allocated to plan participants was $81 million for the year ended December 31, 2010 ($48 million for the year ended December 31, 2009); no shares were allocated to plan participants in 2008. At December 31, 2010, 14.4 million shares out of a total 46.0 million shares held by the ESOP had been allocated to participants’ accounts; 0.9 million shares were released but unallocated; and 30.7 million shares, at a fair value of $1,050 million, were considered unearned.

Treasury Stock

On October 26, 2006, the Company announced that its Board of Directors had approved a share buy-back program, authorizing up to $2 billion to be spent on the repurchase of the Company’s common stock (the “2006 Program”). Purchases under the 2006 Program began in March 2007. In 2008, the Company purchased 21.9 million shares under the 2006 Program, bringing the total number of shares purchased under this program to 48.1 million and bringing the program to a close.

The total number of treasury shares purchased by the Company, including shares received from employees and non-employee directors to pay taxes owed to the Company as a result of the exercise of stock options or the delivery of deferred stock, was 0.5 million in 2010, 0.5 million in 2009 and 23.0 million in 2008.

The Company issues shares for options exercised as well as for the release of deferred and restricted stock out of treasury stock or as new common stock shares. The number of treasury shares issued to employees and non-employee directors under the Company’s option and purchase programs was 7.5 million in 2010, 8.7 million in 2009 and 7.0 million in 2008.

Partners' Capital Notes [Abstract]

Limited Partnership [Text Block]

LIMITED PARTNERSHIP

In early 1998, a subsidiary of the Company purchased the 20 percent limited partner interests of outside investors in a consolidated subsidiary, Chemtech Royalty Associates L.P., for a fair value of $210 million in accordance with wind-up provisions in the partnership agreement. The limited partnership was renamed Chemtech II L.P. (“Chemtech II”). In June 1998, the Company contributed assets with an aggregate fair value of $783 million (through a wholly owned subsidiary) to Chemtech II and an outside investor acquired a limited partner interest in Chemtech II totaling 20 percent in exchange for $200 million. In September 2000, the Company contributed additional assets with an aggregate fair value of $18 million (through a wholly owned subsidiary) to Chemtech II. During the second quarter of 2008, the minority outside investor presented the Company with a liquidation notice, resulting in Dow’s election to purchase the outside investor’s share in the partnership for $200 million. The transaction was completed in the second quarter of 2008.

Prior to the sale of its interest, the outside investor in Chemtech II received a cumulative annual priority return on its investment and participated in residual earnings. For financial reporting purposes, the assets (other than intercompany loans, which were eliminated), liabilities, results of operations and cash flows of the partnership and subsidiaries were included in the Company’s consolidated financial statements, and the outside investor’s limited partner interest was included in “Noncontrolling interests” in the consolidated balance sheets.

The recording of the April 1, 2009 acquisition of Rohm and Haas (see Note D) resulted in goodwill of $9,707 million, which is not deductible for tax purposes. During the first quarter of 2010, goodwill related to the acquisition of Rohm and Haas increased $99 million for net adjustments made during the measurement period to the fair values of the assets acquired and liabilities assumed. In the table above, these adjustments have been retrospectively reflected in the goodwill at January 1, 2010, in accordance with the accounting guidance for business combinations. The adjustments increased goodwill for the operating segments as follows: Electronic and Functional Materials ($33 million), Coatings and Infrastructure Solutions ($47 million), Agricultural Sciences ($2 million), Performance Materials ($4 million) and Performance Plastics ($13 million).

As a result of the June 17, 2010 divestiture of Styron, $141 million of associated goodwill and $16 million of intangible assets were divested (see Note E). On June 1, 2010, the Company divested its Powder Coatings business, including $4 million of associated goodwill, and on October 1, 2010, the Company divested its Hydrocarbon Resins business, including $9 million of associated goodwill.

Goodwill Impairments

During the fourth quarter of 2010, the Company performed its annual impairment tests for goodwill. As a result of this review, it was determined that no additional goodwill impairments existed.

During the fourth quarter of 2009, the Company performed its annual impairment tests for goodwill. As a result of this review, it was determined that the goodwill associated with the Dow Haltermann reporting unit was impaired. The impairment was based on a review of the Dow Haltermann reporting unit performed by management, in which discounted cash flows did not support the carrying value of the goodwill due to poor future projections for the business. As a result, an impairment loss of $7 million was recognized in the fourth quarter of 2009 against the Performance Materials segment.

During the fourth quarter of 2008, the Company performed its annual impairment tests for goodwill. As a result of this review, it was determined that the goodwill associated with the Dow Automotive Systems reporting unit was impaired. The impairment was based on a review of the Dow Automotive Systems reporting unit performed by management, in which discounted cash flows did not support the carrying value of the goodwill due to the severe downturn in the automotive industry and the future projections for the business. As a result, an estimated impairment loss of $209 million was recognized in the fourth quarter of 2008 against the Performance Materials segment. The second step of goodwill impairment testing to determine the implied fair value of goodwill for the Dow Automotive Systems reporting unit was finalized in the first quarter of 2009. No adjustment was required to be made to the estimated impairment loss based on completion of the allocation process.

Also as a result of the 2008 annual tests, it was determined that the goodwill associated with the Polypropylene reporting unit was impaired. The impairment was based on a review of the Polypropylene reporting unit performed by management, in which discounted cash flows did not support the carrying value of the goodwill due to demand decline in North America and Western Europe, as well as significant new industry capacity that came on stream in 2008 and additional industry capacity that was expected in 2009. As a result, an impairment loss of $30 million was recognized in the fourth quarter of 2008 against the Performance Plastics segment.

Recent Accounting Guidance [Text Block]

RECENT ACCOUNTING GUIDANCE

Recently Adopted Accounting Guidance

On January 1, 2010, the Company adopted Accounting Standards Update (“ASU”) 2009-16, “Transfers and Servicing (Topic 860): Accounting for Transfers of Financial Assets.” This ASU is intended to improve the information provided in financial statements concerning transfers of financial assets, including the effects of transfers on financial position, financial performance and cash flows, and any continuing involvement of the transferor with the transferred financial assets. The Company evaluated the impact of adopting the guidance and the terms and conditions in place at January 1, 2010 and determined that certain sales of accounts receivable would be classified as secured borrowings. Under the Company’s sale of accounts receivable arrangements, $915 million was outstanding at January 1, 2010. The maximum amount of receivables available for participation in these programs was $1,939 million at January 1, 2010. See Note O for additional information about transfers of financial assets.

On January 1, 2010, the Company adopted ASU 2009-17, “Consolidations (Topic 810): Improvements to Financial Reporting by Enterprises Involved with Variable Interest Entities,” which amended the consolidation guidance applicable to variable interest entities and required additional disclosures concerning an enterprise’s continuing involvement with variable interest entities. The Company evaluated the impact of this guidance and determined that the adoption resulted in the consolidation of two additional joint ventures, an owner trust and an entity that was used to monetize accounts receivable. At January 1, 2010, $793 million in assets (net of tax, including the impact on “Investment in nonconsolidated affiliates”), $941 million in liabilities, $100 million in noncontrolling interests and a cumulative effect adjustment to retained earnings of $248 million were recorded as a result of the adoption of this guidance. See Note S for additional information about variable interest entities.

On January 1, 2010, the Company adopted ASU 2010-06, “Fair Value Measurements and Disclosures (Topic 820): Improving Disclosures about Fair Value Measurements,” which added disclosure requirements about transfers in and out of Levels 1 and 2 and separate disclosures about activity relating to Level 3 measurements and clarifies existing disclosure requirements related to the level of disaggregation and input and valuation techniques. See Note K for additional disclosures about fair value measurements.

Accounting Guidance Issued But Not Adopted as of December 31, 2010

In October 2009, the FASB issued ASU 2009-13, “Revenue Recognition (Topic 605): Multiple-Deliverable Revenue Arrangements – a consensus of the FASB Emerging Issues Task Force,” which amends the criteria for when to evaluate individual delivered items in a multiple deliverable arrangement and how to allocate consideration received. This ASU is effective for fiscal years beginning on or after June 15, 2010. The adoption of the guidance on January 1, 2011 is not expected to have a material impact on the Company’s consolidated financial statements.

STOCK-BASED COMPENSATION

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

Disclosure of Compensation Related Costs, Share-based Payments [Text Block]

STOCK-BASED COMPENSATION

The Company grants stock-based compensation to employees and non-employee directors in the form of the Employees’ Stock Purchase Plan (“ESPP”) and stock option plans, which include deferred and restricted stock. Information regarding these plans is provided below.

Accounting for Stock-Based Compensation

The Company grants stock-based compensation awards that vest over a specified period or upon employees meeting certain performance and/or retirement eligibility criteria. The fair value of equity instruments issued to employees is measured on the grant date. The fair value of liability instruments issued to employees (specifically, performance deferred stock awards, which are granted to executive employees subject to stock ownership requirements, that provide the recipient the option to elect to receive a cash payment equal to the value of the stock award on the date of delivery) is measured at the end of each quarter. The fair value of equity and liability instruments is expensed over the vesting period or, in the case of retirement, from the grant date to the date on which retirement eligibility provisions have been met and additional service is no longer required.

The Company uses a lattice-based option valuation model to estimate the fair value of stock options, the Black-Scholes option valuation model for subscriptions to purchase shares under the ESPP and Monte Carlo simulation for the market portion of performance deferred stock awards. The weighted-average assumptions used to calculate total stock-based compensation are included in the following table:

	2010		2009		2008
Dividend yield	2.5	%	3.8	%	4.4	%
Expected volatility	47.35	%	43.78	%	29.57	%
Risk-free interest rate	1.28	%	1.61	%	3.42	%
Expected life of stock options granted during period (years)	6.5		6.25		6
Life of Employees’ Stock Purchase Plan (months)	5		9		6.5

The dividend yield assumption for 2010 was based on a 30 percent / 70 percent blend of the Company’s current declared dividend as a percentage of the stock price on the grant date and a 10-year dividend yield average. The dividend yield assumption for 2009 was based on a 10-year dividend yield average. The dividend yield assumption for 2008 was based on the Company’s current declared dividend as a percentage of the stock price on the grant date. The expected volatility assumption for 2009 was based entirely on historical daily volatility, while the expected volatility assumption for 2010 and 2008 was based on an equal weighting of the historical daily volatility and current implied volatility from exchange-traded options for the contractual term of the options. The risk-free interest rate for all years was based on the weighted-average of U.S. Treasury strip rates over the contractual term of the options. The expected life of stock options granted was based on an analysis of historical exercise patterns.

Employees’ Stock Purchase Plan

On February 13, 2003, the Board of Directors authorized a 10-year ESPP, which was approved by stockholders at the Company’s annual meeting on May 8, 2003. Under the 2010 annual offering, most employees were eligible to purchase shares of common stock of the Company valued at up to 10 percent of their annual base earnings. The value is determined using the plan price multiplied by the number of shares subscribed to by the employee. The plan price of the stock is set each year at no less than 85 percent of market price.

Stock Option Plans

Under the 1988 Award and Option Plan (the “1988 Plan”), a plan approved by stockholders, the Company may grant options or shares of common stock to its employees subject to certain annual and individual limits. The terms of the grants are fixed at the grant date. At December 31, 2010, there were 22,612,549 shares available for grant under this plan.

Under the 1994 Non-Employee Directors’ Stock Plan, the Company was previously allowed to grant up to 300,000 options to non-employee directors; however, no additional grants will be made under this plan. At December 31, 2010, there were 34,650 options outstanding under this plan.

Under the 1998 Non-Employee Directors’ Stock Plan, the Company was previously allowed to grant up to 600,000 options to non-employee directors; however, no additional grants will be made under this plan. At December 31, 2010, there were 85,000 options outstanding under this plan.

The exercise price of each stock option equals the market price of the Company’s stock on the date of grant. Options vest from one to three years, and have a maximum term of 10 years.

The following table provides stock option activity for 2010:

TRANSFERS OF FINANCIAL ASSETS

Transfers and Servicing [Abstract]

Transfers and Servicing of Financial Assets [Text Block]

TRANSFERS OF FINANCIAL ASSETS

On January 1, 2010, the Company adopted ASU 2009-16, “Transfers and Servicing (Topic 860): Accounting for Transfers of Financial Assets.” This ASU is intended to improve the information provided in financial statements concerning transfers of financial assets, including the effects of transfers on financial position, financial performance and cash flows, and any continuing involvement of the transferor with the transferred financial assets. The Company evaluated the impact of adopting the guidance and the terms and conditions in place at January 1, 2010 and determined that certain sales of accounts receivable would be classified as secured borrowings. Under the Company’s sale of accounts receivable arrangements, $915 million was outstanding at January 1, 2010. The maximum amount of receivables available for participation in these programs was $1,939 million at January 1, 2010.

In January 2010, the Company terminated the North American arrangement and replaced it with a new arrangement that qualified for treatment as a sale under ASU 2009-16. The arrangement related to $294 million of the $915 million outstanding at January 1, 2010 and $1,100 million of the $1,939 million maximum participation.

In June 2010, the Company terminated the European arrangement and replaced it with a new arrangement that qualified for treatment as a sale under ASU 2009-16. The arrangement related to $584 million of the $915 million outstanding at January 1, 2010 and $721 million of the $1,939 million maximum participation.

Sale of Trade Accounts Receivable in North America

In January 2010, the Company terminated its previous facilities used in North America for the transfers of trade accounts receivable by entering into an agreement to repurchase the outstanding receivables for $264 million and replacing it with a new arrangement. During the year ended December 31, 2010, under the new arrangement, the Company sold the trade accounts receivable of select North America entities on a revolving basis to certain multi-seller commercial paper conduit entities. The Company maintains servicing responsibilities and the related costs are insignificant. The proceeds received are comprised of cash and interests in specified assets (the receivables sold by the Company) of the conduits that entitle the Company to the residual cash flows of such specified assets in the conduits after the commercial paper has been repaid. Neither the conduits nor the investors in those entities have recourse to other assets of the Company in the event of nonpayment by the debtors.

During the year ended December 31, 2010, the Company recognized a loss of $19 million on the sale of these receivables, which is classified as “Interest expense and amortization of debt discount” in the consolidated statements of income. The Company classifies its interests in the conduits as “Accounts and notes receivable – Other” on the consolidated balance sheets and those interests are carried at fair value. Fair value of the interests is determined by calculating the expected amount of cash to be received and is based on unobservable inputs (a Level 3 measurement). The key input in the valuation is percentage of anticipated credit losses, which was 1.42 percent, in the portfolio of receivables sold that have not yet been collected. Given the short-term nature of the underlying receivables, discount rates and prepayments are not factors in determining the fair value of the interests. At December 31, 2010, the carrying value of the interests held was $1,110 million, which is the Company’s maximum exposure to loss related to the receivables sold.

The sensitivity of the fair value of the interests held to hypothetical adverse changes in the anticipated credit losses are as follows (amounts shown are the corresponding hypothetical decreases in the carrying value of the interests):

Impact to Carrying Value In millions
10% adverse change	$	2
20% adverse change	$	5

Following is an analysis of certain cash flows between the Company and the North American conduits:

Sale of receivables	$	264
Collections reinvested in revolving receivables	$	18,952
Interests in conduits (1)	$	974

(1) Presented in "Operating Activities" in the consolidated statements of cash flows.

Delinquencies on the sold receivables that were still outstanding at December 31, 2010 were $127 million. Trade accounts receivable outstanding and derecognized from the Company’s consolidated balance sheets at December 31, 2010 were $1,930 million. Credit losses, net of any recoveries, on receivables sold during the year ended December 31, 2010 were $2 million. During 2010, the Company repurchased $13 million of previously sold receivables related to a divestiture.

Sale of TradeAccounts Receivable in Europe

In June 2010, the Company terminated its previous facility used in Europe for the transfers of trade accounts receivable by entering into an agreement to repurchase the outstanding receivables for $11 million and replacing it with a new arrangement. Since June 2010, under the new arrangement, the Company sold qualifying trade accounts receivable of select European entities on a revolving basis to certain multi-seller commercial paper conduit entities. The Company maintains servicing responsibilities and the related costs are insignificant. The proceeds received are comprised of cash and interests in specified assets (the receivables sold by the Company) of the conduits that entitle the Company to the residual cash flows of such specified assets in the conduits after the commercial paper has been repaid. Neither the conduits nor the investors in those entities have recourse to other assets of the Company in the event of nonpayment by the debtors.

During the period from the June 2010 inception of the new arrangement through December 31, 2010, the Company recognized a loss of $7 million on the sale of these receivables, which is classified as “Interest expense and amortization of debt discount” in the consolidated statements of income. The Company classifies its interests in the conduits as “Accounts and notes receivable – Other” on the consolidated balance sheets and those interests are carried at fair value. Fair value of the interests is determined by calculating the expected amount of cash to be received and is based on unobservable inputs (a Level 3 measurement). The key input in the valuation is percentage of anticipated credit losses, which was zero, in the portfolio of receivables sold that have not yet been collected. Given the short-term nature of the underlying receivables, discount rates and prepayments are not factors in determining the fair value of the interests. At December 31, 2010, the carrying value of the interests held was $157 million, which is the Company’s maximum exposure to loss related to the receivables sold.

Following is an analysis of certain cash flows between the Company and the European conduits:

Cash Proceeds
In millions	2010
Sale of receivables	$	554
Collections reinvested in revolving receivables	$	3,914
Interests in conduits (1)	$	64

(1) Presented in "Operating Activities" in the consolidated statements of cash flows.

Delinquencies on the sold receivables still outstanding at December 31, 2010 were $42 million. Trade accounts receivable outstanding and derecognized from the Company’s consolidated balance sheets at December 31, 2010 were $405 million. There were no credit losses on receivables sold since June 2010.

Sale of Trade Accounts Receivable in Asia Pacific

During the year ended December 31, 2010, the Company sold participating interests in trade accounts receivable of select Asia Pacific entities for which the Company received cash. The Company maintains servicing responsibilities for the participating interests sold and the related costs are insignificant. The third-party holders of the participating interests do not have recourse to the Company’s assets in the event of nonpayment by the debtors.

During the year ended December 31, 2010, the Company recognized a loss of less than $1 million on the sale of the participating interests in the receivables, which is classified as “Interest expense and amortization of debt discount” in the consolidated statements of income.

Following is an analysis of certain cash flows between the Company and the third-party holders of the participating interests:

Cash Proceeds
In millions	2010
Sale of participating interests	$	218
Collections reinvested in revolving receivables	$	195

Following is additional information related to the sale of participating interests in the receivables under this facility:

Trade Accounts Receivable In millions	Dec 31, 2010
Derecognized from the consolidated balance sheet	$	25
Outstanding in the consolidated balance sheet	281
Total accounts receivable in select Asia Pacific entities	$	306

There were no credit losses on receivables relating to the participating interests sold during the year ended December 31, 2010. There were no delinquencies on the outstanding receivables related to the participating interests sold at December 31, 2010.

INCOME TAXES

Income Tax Expense (Benefit) [Abstract]

Income Tax Disclosure [Text Block]

INCOME TAXES

Operating loss carryforwards amounted to $4,572 million at December 31, 2010 and $4,550 million at December 31, 2009. At December 31, 2010, $405 million of the operating loss carryforwards were subject to expiration in 2011 through 2015. The remaining operating loss carryforwards expire in years beyond 2015 or have an indefinite carryforward period. Tax credit carryforwards at December 31, 2010 amounted to $479 million ($656 million at December 31, 2009), net of uncertain tax positions, of which $12 million is subject to expiration in 2011 through 2015. The remaining tax credit carryforwards expire in years beyond 2015.

Undistributed earnings of foreign subsidiaries and related companies that are deemed to be permanently invested amounted to $9,798 million at December 31, 2010, $8,707 million at December 31, 2009 and $8,043 million at December 31, 2008. It is not practicable to calculate the unrecognized deferred tax liability on those earnings.

The Company had valuation allowances that primarily related to the realization of recorded tax benefits on tax loss carryforwards from operations in the United States, Brazil and Asia Pacific of $682 million at December 31, 2010; valuation allowances of $721 million at December 31, 2009 primarily related to the realization of recorded tax benefits on tax loss carryforwards from operations in the United States, Brazil, Asia Pacific and Denmark.

The tax rate for 2010 was positively impacted by a high level of equity earnings as a percentage of total earnings, the release of a tax valuation allowance, a tax law change, and improved financial results in jurisdictions with tax rates that are lower than the U.S. statutory rate. These factors resulted in an effective tax rate of 17.2 percent for 2010.

The tax rate for 2009 was reduced by several factors: a significantly higher level of equity earnings as a percent of total earnings, favorable accrual-to-return adjustments in various geographies, the recognition of domestic losses and an improvement in financial results in jurisdictions with tax rates that are lower than the U.S. statutory rate. These factors resulted in an effective tax rate of negative 20.7 percent for 2009.

The tax rate for 2008 was negatively impacted by increased foreign taxes, declining financial results in jurisdictions with lower tax rates than the United States and goodwill impairment losses that are not deductible for tax purposes (see Note I). Additionally, during 2008, the Company determined that it was more likely than not that certain tax loss carryforwards in the United States and Asia Pacific would not be utilized due to deteriorating market conditions for the Company’s products in these areas, which resulted in increases in valuation allowances of $48 million in the United States and $24 million in Asia Pacific. These events resulted in an effective tax rate for 2008 that was higher than the U.S. statutory rate. The Company’s reported effective tax rate for 2008 was 51.0 percent.

(1) Included in current deferred tax assets are prepaid tax assets totaling $100 million in 2010 and $151 million in 2009.

(2) The Company assumed $2,875 million of deferred tax liabilities with the April 1, 2009 acquisition of Rohm and Haas; see Note D.

Uncertain Tax Positions

At December 31, 2010, the total amount of unrecognized tax benefits was $319 million ($650 million at December 31, 2009), of which $297 million would impact the effective tax rate, if recognized ($610 million at December 31, 2009). The reduction in 2010 was primarily due to settlements of uncertain tax positions with tax authorities.

Interest and penalties associated with uncertain tax positions are recognized as components of the “Provision (Credit) for income taxes,” and totaled $6 million in 2010, $10 million in 2009 and $3 million in 2008. The Company’s accrual for interest and penalties was $58 million at December 31, 2010 and $68 million at December 31, 2009.

The Company is currently under examination in a number of tax jurisdictions. It is reasonably possible that these examinations may be resolved within twelve months. As a result, it is reasonably possible that the total gross unrecognized tax benefits of the Company at December 31, 2010 may be reduced by approximately $30 million to $60 million. The impact on the Company’s results of operations is not expected to be material.

Tax years that remain subject to examination for the Company’s major tax jurisdictions are shown below:

Tax Years Subject to Examination by Major Tax Jurisdiction at December 31

The reserve for non-income tax contingencies related to issues in the United States and foreign locations was $156 million at December 31, 2010 and $189 million at December 31, 2009. This is management’s best estimate of the potential liability for non-income tax contingencies. Inherent uncertainties exist in estimates of tax contingencies due to changes in tax law, both legislated and concluded through the various jurisdictions’ tax court systems. It is the opinion of the Company’s management that the possibility is remote that costs in excess of those accrued will have a material adverse impact on the Company’s consolidated financial statements.

(1) Cash collateral is classified as “Accounts and notes receivable – Other” in the consolidated balance sheets. Amounts represent the estimated net settlement amount when applying netting and set-off rights included in master netting arrangements between the Company and its counterparties and the payable or receivable for cash collateral held or placed with the same counterparty.

(2) Included in “Accounts and notes receivable – Other” in the consolidated balance sheets. See Note O for additional information on transfers of financial assets.

(3) The Company’s investments in equity and debt securities are primarily classified as available-for-sale and are included in “Other investments” in the consolidated balance sheets.

(4) U.S. Treasury obligations, U.S. agency obligations, agency mortgage-backed securities and other municipalities’ obligations.

(5) See Note J for the classification of derivatives in the consolidated balance sheets.

Assets and liabilities related to forward contracts, interest rate swaps, currency swaps, options and other conditional or exchange contracts executed with the same counterparty under a master netting arrangement are netted. Collateral accounts are netted with corresponding assets and liabilities. The Company posted cash collateral of $4 million at December 31, 2010, classified as “Accounts and notes receivable – Other” in the consolidated balance sheets.

For assets and liabilities classified as Level 1 measurements (measured using quoted prices in active markets), total fair value is either the price of the most recent trade at the time of the market close or the official close price, as defined by the exchange on which the asset is most actively traded on the last trading day of the period, multiplied by the number of units held without consideration of transaction costs.

For assets and liabilities classified as Level 2 measurements, where the security is frequently traded in less active markets, fair value is based on the closing price at the end of the period; where the security is less frequently traded, fair value is based on the price a dealer would pay for the security or similar securities, adjusted for any terms specific to that asset or liability. Market inputs are obtained from well-established and recognized vendors of market data and subjected to tolerance/quality checks. For derivative assets and liabilities, standard industry models are used to calculate the fair value of the various financial instruments based on significant observable market inputs, such as foreign exchange rates, commodity prices, swap rates, interest rates and implied volatilities obtained from various market sources.

For all other assets and liabilities for which observable inputs are used, fair value is derived through the use of fair value models, such as a discounted cash flow model or other standard pricing models. See Note J for further information on the types of instruments used by the Company for risk management.

There were no significant transfers between Levels 1 and 2 during the year ended December 31, 2010.

For assets classified as Level 3 measurements, fair value is based on significant unobservable inputs including assumptions where there is little, if any, market activity. The fair value of the Company’s interests held in trade receivable conduits is determined by calculating the expected amount of cash to be received using the key input of anticipated credit losses in the portfolio of receivables sold that have not yet been collected (1.42 percent for North America and zero for Europe at December 31, 2010). Given the short-term nature of the underlying receivables, discount rate and prepayments are not factors in determining the fair value of the interests. See Note O for further information on assets classified as Level 3 measurements.

The following table summarizes the changes in fair value measurements using Level 3 inputs for the year ended December 31, 2010:

Basis of Fair Value Measurements  on a Nonrecurring Basis in 2010	Significant Other Unobservable Inputs		Total Losses
In millions	(Level 3)		2010
Assets at fair value:
Long-lived and other assets	$	—	$	(75	)

After evaluating expected future investments in conjunction with expected future cash flows, a $48 million asset impairment charge was recognized in the Polyurethanes business in the fourth quarter of 2010. The Company’s evaluation of strategic alternatives for Epoxy capacity resulted in an $18 million asset impairment charge in the fourth quarter of 2010. Due to a change in the scope of a capital project, a $9 million asset impairment charge was recognized in Dow Automotive Systems in the fourth quarter of 2010. In all cases, the assets were written down to zero. The charges were included in “Cost of sales” in the consolidated statements of income and reflected in the Performance Materials ($75 million) segment.

The following table summarizes the bases used to measure certain assets and liabilities at fair value on a nonrecurring basis in 2009:

Basis of Fair Value Measurements on a Nonrecurring Basis in 2009	Significant Other Observable Inputs		Significant Other Unobservable Inputs				Total Losses
In millions	(Level 2)		(Level 3)		Total		2009
Assets at fair value:

Goodwill	—		—		—		(7		)
Total assets at fair value	$	1,657	$	30	$	1,687	$	(471	)

As part of the restructuring plan that was approved on June 30, 2009, the Company will shut down a number of manufacturing facilities by the end of 2011. As a result, long-lived assets with a carrying value of $425 million were written down to the fair value of $26 million, resulting in an impairment charge of $399 million, which was included in the second quarter of 2009 restructuring charge (see Note C). In the fourth quarter of 2009, the Company recognized an impairment loss of $65 million (against the Performance Plastics segment) related to its investment in Equipolymers with a remaining fair value of the investment of $4 million. The long-lived assets were valued based on bids received from third parties and using discounted cash flow analysis based on assumptions that market participants would use. Key inputs included anticipated revenues, associated manufacturing costs, capital expenditures and discount, growth and tax rates.

On April 1, 2009, the Company announced the entry into a definitive agreement to sell the newly acquired stock of Morton International, Inc., the Salt business of Rohm and Haas, to K+S Aktiengesellschaft. The assets were classified as held for sale with a net carrying value of $1,657 million at September 30, 2009. The held for sale assets were valued based on the definitive agreement with K+S Aktiengesellschaft, less estimated cost to sell. The assets were sold on October 1, 2009 (see Note E).

During the fourth quarter of 2009, the Company performed its annual impairment tests for goodwill. As a result of this review, it was determined that the goodwill associated with the Dow Haltermann reporting unit was impaired. The impairment was based on a review of the Dow Haltermann reporting unit performed by management, in which discounted cash flows did not support the carrying value of the goodwill due to poor future projections for the business. As a result, an impairment loss of $7 million was recognized in the fourth quarter of 2009 against the Performance Materials segment.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policy)

12 Months Ended

Dec. 31, 2010

Accounting Policies [Abstract]

Consolidation, Policy [Policy Text Block]

Principles of Consolidation and Basis of Presentation

The accompanying consolidated financial statements of The Dow Chemical Company and its subsidiaries (“Dow” or the “Company”) were prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and include the assets, liabilities, revenues and expenses of all majority-owned subsidiaries over which the Company exercises control and, when applicable, entities for which the Company has a controlling financial interest or is the primary beneficiary. Intercompany transactions and balances are eliminated in consolidation. Investments in nonconsolidated affiliates (20-50 percent owned companies, joint ventures and partnerships) are accounted for using the equity method.

Certain changes to prior year balance sheet amounts have been made in accordance with the accounting guidance for business combinations to reflect adjustments made during the measurement period to provisional amounts recorded for assets acquired and liabilities assumed from Rohm and Haas Company (“Rohm and Haas”) on April 1, 2009. Certain changes have been made to geographic area information for prior years to reflect changes made in the first quarter of 2010. Certain changes have been made to operating segment information to reflect changes made in the third quarter of 2011 related to changes in the Company’s organization. A change to current year balance sheet amounts has been made to properly classify the current portion of "Deferred charges and other assets" of $349 million to "Other current assets."

Use of Estimates, Policy [Policy Text Block]

Use of Estimates in Financial Statement Preparation

The preparation of financial statements in accordance with U.S. GAAP requires the use of estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. The Company’s consolidated financial statements include amounts that are based on management’s best estimates and judgments. Actual results could differ from those estimates.

Foreign Currency Transactions and Translations Policy [Policy Text Block]

Foreign Currency Translation

The local currency has been primarily used as the functional currency throughout the world. Translation gains and losses of those operations that use local currency as the functional currency are included in the consolidated balance sheets in “Accumulated other comprehensive income (loss)” (“AOCI”). Where the U.S. dollar is used as the functional currency, foreign currency gains and losses are reflected in income.

Environmental Costs, Policy [Policy Text Block]

Environmental Matters

Accruals for environmental matters are recorded when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated based on current law and existing technologies. These accruals are adjusted periodically as assessment and remediation efforts progress or as additional technical or legal information becomes available. Accruals for environmental liabilities are included in the consolidated balance sheets in “Accrued and other current liabilities” and “Other noncurrent obligations” at undiscounted amounts. Accruals for related insurance or other third-party recoveries for environmental liabilities are recorded when it is probable that a recovery will be realized and are included in the consolidated balance sheets as “Accounts and notes receivable - Other.”

Environmental costs are capitalized if the costs extend the life of the property, increase its capacity, and/or mitigate or prevent contamination from future operations. Environmental costs are also capitalized in recognition of legal asset retirement obligations resulting from the acquisition, construction and/or normal operation of a long-lived asset. Costs related to environmental contamination treatment and cleanup are charged to expense. Estimated future incremental operations, maintenance and management costs directly related to remediation are accrued when such costs are probable and reasonably estimable.

Cash and Cash Equivalents, Policy [Policy Text Block]

Cash and Cash Equivalents

Cash and cash equivalents include time deposits and readily marketable securities with original maturities of three months or less.

Financial Instruments Accounting Policies [Text Block]

Financial Instruments

The Company calculates the fair value of financial instruments using quoted market prices whenever available. When quoted market prices are not available for various types of financial instruments (such as forwards, options and swaps), the Company uses standard pricing models with market-based inputs that take into account the present value of estimated future cash flows.

The Company utilizes derivatives to manage exposures to currency exchange rates, commodity prices and interest rate risk. The fair values of all derivatives are recognized as assets or liabilities at the balance sheet date. Changes in the fair value of these instruments are reported in income or AOCI, depending on the use of the derivative and whether it qualifies for hedge accounting treatment.

Gains and losses on derivatives that are designated and qualify as cash flow hedging instruments are recorded in AOCI, to the extent the hedges are effective, until the underlying transactions are recognized in income. To the extent effective, gains and losses on derivative and nonderivative instruments used as hedges of the Company’s net investment in foreign operations are recorded in AOCI as part of the cumulative translation adjustment. The ineffective portions of cash flow hedges and hedges of net investment in foreign operations, if any, are recognized in income immediately.

Gains and losses on derivatives designated and qualifying as fair value hedging instruments, as well as the offsetting losses and gains on the hedged items, are reported in income in the same accounting period. Derivatives not designated as hedging instruments are marked-to-market at the end of each accounting period with the results included in income.

Inventory, Policy [Policy Text Block]

Inventories

Inventories are stated at the lower of cost or market. The method of determining cost for each subsidiary varies among last-in, first-out (“LIFO”); first-in, first-out (“FIFO”); and average cost, and is used consistently from year to year.

Property, Plant and Equipment, Policy [Policy Text Block]

Property

Land, buildings and equipment, including property under capital lease agreements, are carried at cost less accumulated depreciation. Depreciation is based on the estimated service lives of depreciable assets and is calculated using the straight-line method, unless the asset was capitalized before 1997 when the declining balance method was used. Fully depreciated assets are retained in property and accumulated depreciation accounts until they are removed from service. In the case of disposals, assets and related accumulated depreciation are removed from the accounts, and the net amounts, less proceeds from disposal, are included in income.

Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block]

Impairment and Disposal of Long-Lived Assets

The Company evaluates long-lived assets and certain identifiable intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. When undiscounted future cash flows are not expected to be sufficient to recover an asset’s carrying amount, the asset is written down to its fair value based on bids received from third parties or a discounted cash flow analysis based on market participant assumptions.

Long-lived assets to be disposed of by sale are classified as held for sale and are reported at the lower of carrying amount or fair value less cost to sell, and depreciation is ceased. Long-lived assets to be disposed of other than by sale are classified as held and used until they are disposed of and are reported at the lower of carrying amount or fair value, and depreciation is recognized over the remaining useful life of the assets.

Goodwill and Intangible Assets, Policy [Policy Text Block]

Goodwill and Other Intangible Assets

The Company records goodwill when the purchase price of a business acquisition exceeds the estimated fair value of net identified tangible and intangible assets acquired. Goodwill is tested for impairment at the reporting unit level annually, or more frequently when events or changes in circumstances indicate that the fair value of a reporting unit has more likely than not declined below its carrying value. The Company primarily utilizes a discounted cash flow methodology to calculate the fair value of its reporting units.

Finite-lived intangible assets such as purchased customer lists, licenses, intellectual property, patents, trademarks and software, are amortized over their estimated useful lives, generally on a straight-line basis for periods ranging primarily from three to twenty years. Finite-lived intangible assets are reviewed for impairment or obsolescence annually, or more frequently when events or changes in circumstances indicate that the carrying amount of an intangible asset may not be recoverable. If impaired, intangible assets are written down to fair value based on discounted cash flows.

Asset Retirement Obligations, Policy [Policy Text Block]

Asset Retirement Obligations

The Company records asset retirement obligations as incurred and reasonably estimable, including obligations for which the timing and/or method of settlement are conditional on a future event that may or may not be within the control of the Company. The fair values of obligations are recorded as liabilities on a discounted basis and are accreted over time for the change in present value. Costs associated with the liabilities are capitalized and amortized over the estimated remaining useful life of the asset, generally for periods of 10 years or less.

Investment, Policy [Policy Text Block]

Investments

Investments in debt and marketable equity securities (including warrants), primarily held by the Company’s insurance operations, are classified as trading, available-for-sale or held-to-maturity. Investments classified as trading are reported at fair value with unrealized gains and losses included in income. Those classified as available-for-sale are reported at fair value with unrealized gains and losses recorded in AOCI. Those classified as held-to-maturity are recorded at amortized cost. The cost of investments sold is determined by specific identification. The Company routinely reviews available-for-sale and held-to-maturity securities for other-than-temporary declines in fair value below the cost basis, and when events or changes in circumstances indicate the carrying value of an asset may not be recoverable, the security is written down to fair value, establishing a new cost basis.

Revenue Recognition, Policy [Policy Text Block]

Revenue

Sales are recognized when the revenue is realized or realizable, and the earnings process is complete. Approximately 99 percent of the Company’s sales in 2010 related to sales of product. The remaining 1 percent in 2010 related to the Company’s service offerings, insurance operations, and licensing of patents and technology. Revenue for product sales is recognized as risk and title to the product transfer to the customer, which usually occurs at the time shipment is made. As such, title to the product passes when the product is delivered to the freight carrier. Dow’s standard terms of delivery are included in its contracts of sale, order confirmation documents and invoices. Freight costs and any directly related costs of transporting finished product to customers are recorded as “Cost of sales.”

Revenue related to the Company’s insurance operations includes third-party insurance premiums, which are earned over the terms of the related insurance policies and reinsurance contracts. Revenue related to the initial licensing of patents and technology is recognized when earned; revenue related to running royalties is recognized according to licensee production levels.

Legal Costs, Policy [Policy Text Block]

Legal Costs

The Company expenses legal costs, including those legal costs expected to be incurred in connection with a loss contingency, as incurred.

Severance Costs [Policy Text Block]

Severance Costs

The Company routinely reviews its operations around the world in an effort to ensure competitiveness across its businesses and geographic areas. When the reviews result in a workforce reduction related to the shutdown of facilities or other optimization activities, severance benefits are provided to employees primarily under Dow’s ongoing benefit arrangements. These severance costs are accrued under the guidance of the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification™ (“ASC”) Topic 712, “Compensation – Nonretirement Postemployment Benefits,” once management commits to a plan of termination including the number of employees to be terminated, their job classifications or functions, their locations and the expected completion date.

Income Tax, Policy [Policy Text Block]

Income Taxes

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 of temporary differences between the carrying amounts and tax bases of assets and liabilities using enacted rates. The effect of a change in tax rates on deferred tax assets is recognized in income in the period that includes the enactment date.

Annual tax provisions include amounts considered sufficient to pay assessments that may result from examinations of prior year tax returns; however, the amount ultimately paid upon resolution of issues raised may differ from the amounts accrued.

The Company recognizes the financial statement effects of an uncertain income tax position when it is more likely than not, based on the technical merits, that the position will be sustained upon examination. The Company accrues for other tax contingencies when it is probable that a liability to a taxing authority has been incurred and the amount of the contingency can be reasonably estimated. The current portion of uncertain income tax positions is included in “Income taxes payable” and the long-term portion is included in “Other noncurrent obligations” in the consolidated balance sheets.

Provision is made for taxes on undistributed earnings of foreign subsidiaries and related companies to the extent that such earnings are not deemed to be permanently invested.

Earnings Per Share, Policy [Policy Text Block]

Earnings per Common Share

The calculation of earnings per common share is based on the weighted-average number of the Company’s common shares outstanding for the applicable period. The calculation of diluted earnings per common share reflects the effect of all potential dilutive common shares that were outstanding during the respective periods, unless the effect of doing so is antidilutive.
