PRODUCTS, SERVICES AND STRATEGIES

Chlor Alkali Products

Products and Services

We have been involved in the U.S. chlor alkali industry for more than 100 years and are a major participant in the North American chlor alkali market. Chlorine, caustic soda and hydrogen are co-produced commercially by the electrolysis of salt. These co-products are produced simultaneously, and in a fixed ratio of 1.0 ton of chlorine to 1.1 tons of caustic soda. The industry refers to this as an Electrochemical Unit or ECU. With a demonstrated capacity as of the end of 2009 of 1.95 million ECUs per year, including 50% of the production from our partnership with PolyOne Corporation (PolyOne), which we refer to as SunBelt, we are the third largest chlor alkali producer, measured by production volume of chlorine and caustic soda, in North America, according to data from Chemical Market Associates, Inc. (CMAI). CMAI is a global petrochemical, plastics and fibers consulting firm established in 1979. Approximately 55% of our caustic soda production is high purity membrane and rayon grade, which, according to CMAI data, normally commands a premium selling price in the market. According to data from CMAI, we are the largest North American producer of industrial bleach, which is manufactured using both chlorine and caustic soda.

Our manufacturing facilities in Augusta, GA; McIntosh, AL; Charleston, TN; St. Gabriel, LA; Henderson, NV; Becancour, Quebec; and a portion of our facility in Niagara Falls, NY are ISO 9002 certified. In addition, Augusta, GA; McIntosh, AL; Charleston, TN; and Niagara Falls, NY are ISO 14001 certified. ISO 9000 (which includes ISO 9001 and ISO 9002) and ISO 14000 (which includes ISO 14001) are sets of related international standards on quality assurance and environmental management developed by the International Organization for Standardization to help companies effectively document the quality and environmental management system elements to be implemented to maintain effective quality and environmental management systems. Our facilities in Augusta, GA; McIntosh, AL; Charleston, TN; Niagara Falls, NY; and St. Gabriel, LA have also achieved Star status in the Voluntary Protection Program (VPP) of the Occupational Safety and Health Administration (OSHA). OSHA’s VPP is a program in which companies voluntarily participate that recognizes facilities for their exemplary safety and health programs. Our Augusta, GA; McIntosh, AL; Charleston, TN; and Niagara Falls, NY chlor alkali manufacturing sites and the division headquarters are accredited under the RC 14001 Responsible Care® (RC 14001) standard. Supported by the chemical industry and recognized by government and regulatory agencies, RC 14001 establishes requirements for the management of safety, health, environmental, security, transportation, product stewardship, and stakeholder engagement activities for the business.

Chlorine is used as a raw material in the production of thousands of products for end-uses including vinyls, chlorinated intermediates, isocyanates, and water treatment. A significant portion of U.S. chlorine production is consumed in the manufacture of ethylene dichloride, or EDC, a precursor for polyvinyl chloride, or PVC. PVC is a plastic used in applications such as vinyl siding, plumbing and automotive parts. We estimate that approximately 11% of our chlorine produced, including the production from our share of SunBelt, is consumed in the manufacture of EDC. While much of the chlorine produced in the U.S. is consumed by the producing company to make downstream products, we sell most of the chlorine we produce to third parties in the merchant market.

Caustic soda has a wide variety of end-use applications, the largest of which is in the pulp and paper industry used in the delignification and bleaching portion of the pulping process. Caustic soda is also used in the production of detergents and soaps, alumina and a variety of other inorganic and organic chemicals.

The chlor alkali industry is cyclical, both as a result of changes in demand for each of the co-products and as a result of the large increments in which new capacity is added and removed. Because chlorine and caustic are produced in a fixed ratio, the supply of one product can be constrained both by the physical capacity of the production facilities and/or by the ability to sell the co-product. Prices for both products respond rapidly to changes in supply and demand. Our ECU netbacks (defined as gross selling price less freight and discounts) averaged approximately $520, $635 and $535 per ECU in 2009, 2008 and 2007, respectively.

Beginning in late 2006, driven by reduced levels of chlorine demand and a series of planned and unplanned plant maintenance outages, chlor alkali plant operating rates for the industry were reduced. While this allowed chlorine supply to stay balanced, it caused caustic soda demand, which did not experience a decline, to exceed supply. This led to industry-wide caustic soda price increases. During the first three quarters of 2008, North American demand for caustic soda remained strong. However, caustic soda supply continued to be constrained by the weakness in chlorine demand, which caused operating rates to be reduced. This resulted in a significant supply and demand imbalance for caustic soda in North America. This imbalance, combined with increased freight and energy costs, resulted in our achieving record levels of caustic soda pricing. During the fourth quarter of 2008, North American caustic soda demand weakened but less than the decline in chlorine demand. This caused the caustic soda supply and demand imbalance to continue, which continued to support record levels of caustic soda prices. The result was a record ECU netback, in our system, in the first quarter of 2009.

Our 2009 ECU netbacks of $520 were 18% lower than the 2008 netbacks of $635, reflecting the changes in the pricing dynamics in North America. Beginning late in the fourth quarter of 2008 and continuing through 2009, demand for caustic soda weakened significantly, and fell below the demand for chlorine. This created excess supply in North America, which has caused caustic soda prices to fall. The over supply of caustic soda caused industry operating rates to be constrained, which resulted in chlorine price increase announcements of $300 per ton during the second quarter of 2009. Caustic soda prices declined precipitously in the second quarter of 2009 and these declines continued into the third quarter of 2009. During the third quarter of 2009, chlorine and caustic soda demand became more balanced eliminating the oversupply of caustic soda. We began realizing increases in chlorine prices in the third quarter of 2009 with most of the improvement in the fourth quarter of 2009. We believe that ECU netbacks, in our system, have bottomed out in the third quarter of 2009. During the fourth quarter of 2009, as caustic soda demand improved, chlorine production declined due to seasonally weaker demand. This resulted in a supply and demand imbalance for caustic soda in North America. As a result of this imbalance, in December 2009, a $75 per ton caustic soda price increase was announced. We expect to begin realizing this price increase in caustic soda in the second quarter of 2010.

Electricity and salt are the major purchased raw materials for our Chlor Alkali Products segment. Raw materials represent approximately 48% of the total cost of producing an ECU. Electricity is the single largest raw material component in the production of chlor alkali products. During the past five years, we experienced an increase in the cost of electricity from our suppliers due primarily to energy cost increases and regulatory requirements. We are supplied by utilities that primarily utilize coal, hydroelectric, natural gas, and nuclear power. The commodity nature of this industry places an added emphasis on cost management and we believe that we have managed our manufacturing costs in a manner that makes us one of the low cost producers in the industry. During the fourth quarter of 2009, we completed a conversion and expansion project at our St. Gabriel, LA facility and initiated production. This project increased capacity at this location from 197,000 ECUs to 246,000 ECUs and will significantly reduce the site’s manufacturing costs. In addition, as market demand requires, we believe the design of the SunBelt plant, as well as the new design of the St. Gabriel, LA facility, will enable us to expand capacity cost-effectively at these locations.

We also manufacture and sell other chlor alkali-related products. These products include chemically processed salt, hydrochloric acid, sodium hypochlorite (bleach), hydrogen, sodium hydrosulfite, and potassium hydroxide. We have recently invested in capacity and product upgrades in bleach and hydrochloric acid. In the fourth quarter of 2009, we initiated bleach manufacturing and shipping by railroad expansion projects at three of our chlor alkali facilities. We are also actively developing a low salt, high strength bleach facility that will double the concentration of the bleach we manufacture, which should significantly reduce transportation costs. During 2010, we expect to initiate a $15 million to $20 million capital project to construct a low salt, high strength bleach facility to be co-located at one of our existing chlor alkali facilities.

The following table lists products of our Chlor Alkali Products business, with principal products on the basis of annual sales highlighted in bold face.

Strategies

Continued Role as a Preferred Supplier to Merchant Market Customers. Based on our market research, we believe our Chlor Alkali Products business is viewed as a preferred supplier by our merchant market customers. We will continue to focus on providing quality customer service support and developing relationships with our valued customers.

Pursue Incremental Expansion Opportunities. We have invested in capacity and product upgrades in our chemically processed salt, hydrochloric acid, bleach, potassium hydroxide and hydrogen businesses. These expansions increase our captive use of chlorine while increasing the sales of these co-products. These niche businesses provide opportunities to upgrade chlorine and caustic to higher value-added applications. We also have the opportunity, when business conditions permit, to pursue incremental expansion through our SunBelt and St. Gabriel, LA facilities.

Winchester

Products and Services

Winchester is in its 143rd year of operation and its 79th year as part of Olin. Winchester is a premier developer and manufacturer of small caliber ammunition for sale to domestic and international retailers (commercial customers), law enforcement agencies and domestic and international militaries. We believe we are a leading U.S. producer of ammunition for recreational shooters, hunters, law enforcement agencies and the U.S. Armed Forces. As an example of our law enforcement business, the Federal Bureau of Investigation (FBI) awarded Winchester a five-year contract in 2007 for bonded pistol ammunition and, in 2009, we received a Department of Homeland Security (DHS) contract for pistol ammunition. Our legendary Winchester® product line includes all major gauges and calibers of shotgun shells, rimfire and centerfire ammunition for pistols and rifles, reloading components and industrial cartridges. We believe we are the leading U.S. supplier of small caliber commercial ammunition. In support of our continuous improvement initiatives, our manufacturing facilities in East Alton, IL, achieved ISO recertification to the ISO 9001:2008 standard in December 2009. Additionally our facility in Australia was upgraded to the ISO 9001:2008 standard in February 2009 and our manufacturing facility in Oxford, MS achieved ISO 9001:2008 recertification in January 2010.

Winchester has strong relationships throughout the sales and distribution chain and strong ties to traditional dealers and distributors. Winchester has also built its business with key high volume mass merchants and specialty sporting goods retailers. We have consistently developed industry-leading ammunition. In 2009, Winchester was named “Ammunition Manufacturer of the Year” for the second consecutive year by the National Association of Sporting Goods Wholesalers, the carton for Winchester’s 2008 Theodore Roosevelt Commemorative Ammunition was honored with a “2009 Excellence Award” from the Paperboard Packaging Council, the International Hunter Education Association (IHEA) presented Winchester with the “Gladney Davidson Memorial Award,” its most prestigious honor, and Winchester’s new web-based ballistics calculator received the 2009 SHOT Show “Editor’s Choice” award from Shooting Sports Retailer magazine. In 2010, the Winchester® Supreme Elite™ Bonded PDX1™ product line will receive the National Rifle Association’s “Golden Bullseye Award” in the ammunition category from its Shooting Illustrated magazine and Winchester has additionally been honored with the “2010 Cabela Lifetime Business Achievement Award” from the U.S. Sportsmen’s Alliance (USSA).

Winchester purchases raw materials such as copper-based strip and ammunition cartridge case cups and lead from vendors based on a conversion charge or premium. These conversion charges or premiums are in addition to the market prices for metal as posted on exchanges such as the Commodity Exchange, or COMEX, and London Metals Exchange, or LME. Winchester’s other main raw material is propellant, which is purchased predominantly from one of the United States’ largest propellant suppliers.

The following table lists products and services of our Winchester business, with principal products on the basis of annual sales highlighted in bold face.

Strategies

Leverage Existing Strengths. Winchester plans to seek new opportunities to leverage the legendary Winchester brand name and will continue to offer a full line of ammunition products to the markets we serve, with specific focus on investments that lower our costs and that make Winchester ammunition the retail brand of choice.

Focus on Product Line Growth. With a long record of pioneering new product offerings, Winchester has built a strong reputation as an industry innovator. This includes the introduction of reduced-lead and non-lead products, which are growing in popularity for use in indoor shooting ranges and for outdoor hunting.

INTERNATIONAL OPERATIONS

Our subsidiary, PCI Chemicals Canada Company/Société PCI Chimie Canada, operates one chlor alkali facility in Becancour, Quebec, which sells chlor alkali-related products within Canada and to the United States. Our subsidiary, Winchester Australia Limited, loads and packs sporting and industrial ammunition in Australia. See the Note “Segment Information” of the notes to consolidated financial statements in Item 8, for geographic segment data. We are incorporating our segment information from that Note into this section of our Form 10-K.

CUSTOMERS AND DISTRIBUTION

During 2009, no single customer accounted for more than 10% of sales. Sales to all U.S. government agencies and sales under U.S. government contracting activities in total accounted for approximately 5% of sales in 2009. Products we sell to industrial or commercial users or distributors for use in the production of other products constitute a major part of our total sales. We sell some of our products, such as caustic soda and sporting ammunition, to a large number of users or distributors, while we sell others, such as chlorine, in substantial quantities to a relatively small number of industrial users. We discuss the customers for each of our two businesses in more detail above under “Products and Services.”

We market most of our products and services primarily through our sales force and sell directly to various industrial customers, wholesalers, other distributors, and the U.S. Government and its prime contractors.

Because we engage in some government contracting activities and make sales to the U.S. Government, we are subject to extensive and complex U.S. Government procurement laws and regulations. These laws and regulations provide for ongoing government audits and reviews of contract procurement, performance and administration. Failure to comply, even inadvertently, with these laws and regulations and with laws governing the export of munitions and other controlled products and commodities could subject us or one or more of our businesses to civil and criminal penalties, and under certain circumstances, suspension and debarment from future government contracts and the exporting of products for a specified period of time.

BACKLOG

The total amount of contracted backlog was approximately $231.2 million and $228.8 million as of January 31, 2010 and 2009, respectively. The backlog orders are in our Winchester business. Backlog is comprised of all open customer orders not yet shipped. Approximately 70% of contracted backlog as of January 31, 2010 is expected to be filled during 2010.

COMPETITION

We are in active competition with businesses producing the same or similar products, as well as, in some instances, with businesses producing different products designed for the same uses.

Chlor alkali manufacturers in North America, with approximately 15.2 million tons of chlorine and 16.2 million tons of caustic soda capacity, account for approximately 20% of worldwide chlor alkali production capacity. According to CMAI, the Dow Chemical Company (Dow), and the Occidental Chemical Corporation (OxyChem), are the two largest chlor alkali producers in North America. Approximately 75% of the total North American capacity is located in the U.S. Gulf Coast region.

Many of our competitors are integrated producers of chlorine, using some, or all, of their chlorine production in the manufacture of other downstream products. In contrast, we are primarily a merchant producer of chlorine and sell the majority of our chlorine to merchant customers. We do utilize chlorine to manufacture industrial bleach and hydrochloric acid. As a result, we supply a greater share of the merchant chlorine market than our share of overall industry capacity. There is a worldwide market for caustic soda, which attracts imports and allows exports depending on market conditions. All of our competitors sell caustic soda into the North American merchant market.

The chlor alkali industry in North America is highly competitive, and many of our competitors, including Dow and OxyChem, are substantially larger and have greater financial resources than we do. While the technologies to manufacture and transport chlorine and caustic soda are widely available, the production facilities require large capital investments, and are subject to significant regulatory and permitting requirements.

We are among the largest manufacturers in the United States of commercial small caliber ammunition based on independent market research sponsored by the Sporting Arms and Ammunition Manufacturers’ Institute (SAAMI) and the National Shooting Sports Foundation. Founded in 1926, SAAMI is an association of the nation’s leading manufacturers of sporting firearms, ammunition and components. According to SAAMI, our Winchester business, Alliant Techsystems Inc. (ATK) and Remington Arms Company, Inc. (Remington) are the three largest commercial ammunition manufacturers in the United States. The ammunition industry is highly competitive with us, ATK, Remington, numerous smaller domestic manufacturers and foreign producers competing for sales to the commercial ammunition customers. Many factors influence our ability to compete successfully, including price, delivery, service, performance, product innovation and product recognition and quality, depending on the product involved.

EMPLOYEES

As of December 31, 2009, we had approximately 3,700 employees, with 3,500 working in the United States and 200 working in foreign countries, primarily Canada. Various labor unions represent a majority of our hourly-paid employees for collective bargaining purposes.

The following labor contract is scheduled to expire in 2010:

Location		Number of Employees		Expiration Date
Henderson, NV (Chlor Alkali)		70		March 2010

While we believe our relations with our employees and their various representatives are generally satisfactory, we cannot assure that we can conclude this labor contract or any other labor agreements without work stoppages and cannot assure that any work stoppages will not have a material adverse effect on our business, financial condition, or results of operations.

RESEARCH ACTIVITIES; PATENTS

Our research activities are conducted on a product-group basis at a number of facilities. Company-sponsored research expenditures were $2.2 million in 2009 and $2.0 million in 2008 and 2007.

We own or license a number of patents, patent applications, and trade secrets covering our products and processes. We believe that, in the aggregate, the rights under our patents and licenses are important to our operations, but we do not consider any individual patent or license or group of patents and licenses related to a specific process or product to be of material importance to our total business.

RAW MATERIALS AND ENERGY

We purchase the major portion of our raw material requirements. The principal basic raw materials for our production of chlor alkali products are salt, electricity, potassium chloride, sulfur dioxide, and hydrogen. A portion of the salt used in our Chlor Alkali Products segment is produced from internal resources. Lead, brass, and propellant are the principal raw materials used in the Winchester business. We typically purchase our electricity, salt, potassium chloride, sulfur dioxide, ammunition cartridge case cups and copper-based strip, and propellants pursuant to multi-year contracts. We provide additional information with respect to specific raw materials in the tables set forth under “Products and Services.”

Electricity is the predominant energy source for our manufacturing facilities. Most of our facilities are served by utilities which generate electricity principally from coal, hydroelectric and nuclear power except at St. Gabriel, LA and Henderson, NV which predominantly use natural gas.

ENVIRONMENTAL AND TOXIC SUBSTANCES CONTROLS

In the United States, the establishment and implementation of federal, state and local standards to regulate air, water and land quality affect substantially all of our manufacturing locations. Federal legislation providing for regulation of the manufacture, transportation, use and disposal of hazardous and toxic substances, and remediation of contaminated sites has imposed additional regulatory requirements on industry, particularly the chemicals industry. In addition, implementation of environmental laws, such as the Resource Conservation and Recovery Act and the Clean Air Act, has required and will continue to require new capital expenditures and will increase operating costs. Our Canadian facility is governed by federal environmental laws administered by Environment Canada and by provincial environmental laws enforced by administrative agencies. Many of these laws are comparable to the U.S. laws described above. We employ waste minimization and pollution prevention programs at our manufacturing sites and we are a party to various governmental and private environmental actions associated with former waste disposal sites and past manufacturing facilities. Charges or credits to income for investigatory and remedial efforts were material to operating results in the past three years and may be material to operating results in future years.

See our discussion of our environmental matters in Item 3, “Legal Proceedings” below, the Note “Environmental” of the notes to consolidated financial statements contained in Item 8, and Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

Item 1A. RISK FACTORS

In addition to the other information in this Form 10-K, the following factors should be considered in evaluating Olin and our business. All of our forward-looking statements should be considered in light of these factors. Additional risks and uncertainties that we are unaware of or that we currently deem immaterial also may become important factors that affect us.

Sensitivity to Global Economic Conditions and Cyclicality—Our operating results could be negatively affected during economic downturns.

The business of most of our customers, particularly our vinyl, urethanes, and pulp and paper customers are, to varying degrees, cyclical and have historically experienced periodic downturns. These economic and industry downturns have been characterized by diminished product demand, excess manufacturing capacity and, in some cases, lower average selling prices. Therefore, any significant downturn in our customers’ businesses or in global economic conditions could result in a reduction in demand for our products and could adversely affect our results of operations or financial condition.

Although we do not generally sell a large percentage of our products directly to customers abroad, a large part of our financial performance is dependent upon a healthy economy beyond North America. Our customers sell their products abroad. As a result, our business is affected by general economic conditions and other factors in Western Europe and most of East Asia, particularly China and Japan, including fluctuations in interest rates, customer demand, labor costs, currency changes, and other factors beyond our control. The demand for our customers’ products, and therefore, our products, is directly affected by such fluctuations. In addition, our customers could decide to move some or all of their production to lower cost, offshore locations, and this could reduce demand in North America for our products. We cannot assure you that events having an adverse effect on the industries in which we operate will not occur or continue, such as a downturn in the Western European, Asian or world economies, increases in interest rates, or unfavorable currency fluctuations. Economic conditions in other regions of the world, predominantly Asia and Europe, can increase the amount of caustic soda produced and available for export to North America. The increased caustic soda supply can put downward pressure on our caustic soda prices, negatively impacting our profitability.

Cyclical Pricing Pressure—Our profitability could be reduced by declines in average selling prices of our products, particularly declines in the ECU netback for chlorine and caustic.

Our historical operating results reflect the cyclical and sometimes volatile nature of the chemical and ammunition industries. We experience cycles of fluctuating supply and demand in each of our business segments, particularly in Chlor Alkali Products, which result in changes in selling prices. Periods of high demand, tight supply and increasing operating margins tend to result in increases in capacity and production until supply exceeds demand, generally followed by periods of oversupply and declining prices. The significant North American chlor alkali capacity (over 100,000 annual ECU’s) which became operational during 2009 was at the Shintech, Inc. facility in Plaquemine, LA. In North America, because Shintech consumes the chlorine it produces, this expansion may result in more caustic soda supply in the market. Dow announced the permanent closure in 2009 of a portion of their Oyster Creek (Freeport), TX facility. Another factor influencing demand and pricing for chlorine and caustic soda is the price of natural gas. Higher natural gas prices increase our customers’ and competitors’ manufacturing costs, and depending on the ratio of crude oil to gas prices, could make them less competitive in world markets. Continued expansion offshore, particularly in Asia, will continue to have an impact on the ECU values as imported caustic soda replaces some capacity in the U.S.

Price in the chlor alkali industry is the major supplier selection criterion. We have little or no ability to influence prices in this large commodity market. Decreases in the average selling prices of our products could have a material adverse effect on our profitability. For example, assuming all other costs remain constant and internal consumption remains approximately the same, a $10 per ECU selling price change equates to an approximate $17 million annual change in our revenues and pretax profit when we are operating at full capacity. While we strive to maintain or increase our profitability by reducing costs through improving production efficiency, emphasizing higher margin products, and by controlling transportation, selling, and administration expenses, we cannot assure you that these efforts will be sufficient to offset fully the effect of decreases in pricing on operating results.

Because of the cyclical nature of our businesses, we cannot assure you that pricing or profitability in the future will be comparable to any particular historical period, including the most recent period shown in our operating results. We cannot assure you that the chlor alkali industry will not experience adverse trends in the future, or that our operating results and/or financial condition will not be adversely affected by them.

Our Winchester segment is also subject to changes in operating results as a result of cyclical pricing pressures, but to a lesser extent than the Chlor Alkali Products segment. Selling prices of ammunition are affected by changes in raw material costs and availability and customer demand, and declines in average selling prices of our Winchester segment could adversely affect our profitability.

Imbalance in Demand for Our Chlor Alkali Products—A loss of a substantial customer for our chlorine or caustic soda could cause an imbalance in demand for these products, which could have an adverse effect on our results of operations.

Chlorine and caustic soda are produced simultaneously and in a fixed ratio of 1.0 ton of chlorine to 1.1 tons of caustic soda. The loss of a substantial chlorine or caustic soda customer could cause an imbalance in demand for our chlorine and caustic soda products. An imbalance in demand may require us to reduce production of both chlorine and caustic soda or take other steps to correct the imbalance. Since we cannot store chlorine, we may not be able to respond to an imbalance in demand for these products as quickly or efficiently as some of our competitors. If a substantial imbalance occurred, we would need to reduce prices or take other actions that could have a negative impact on our results of operations and financial condition.

Environmental Costs—We have ongoing environmental costs, which could have a material adverse effect on our financial position or results of operations.

The nature of our operations and products, including the raw materials we handle, exposes us to the risk of liabilities or claims with respect to environmental matters. In addition, we are party to various governmental and private environmental actions associated with past manufacturing facilities and former waste disposal sites. We have incurred, and expect to incur, significant costs and capital expenditures in complying with environmental laws and regulations.

The ultimate costs and timing of environmental liabilities are difficult to predict. Liabilities under environmental laws relating to contaminated sites can be imposed retroactively and on a joint and several basis. One liable party could be held responsible for all costs at a site, regardless of fault, percentage of contribution to the site or the legality of the original disposal. We could incur significant costs, including cleanup costs, natural resources damages, civil or criminal fines and sanctions and third-party lawsuits claiming, for example, personal injury and/or property damage, as a result of past or future violations of, or liabilities under, environmental or other laws.

In addition, future events, such as changes to or more rigorous enforcement of environmental laws, could require us to make additional expenditures, modify or curtail our operations and/or install pollution control equipment.

Accordingly, it is possible that some of the matters in which we are involved or may become involved may be resolved unfavorably to us, which could materially adversely affect our financial position or results of operations. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations-Environmental Matters.”

Effects of Regulation—Changes in legislation or government regulations or policies, including tax policies, could have a material adverse effect on our financial position or results of operations.

Legislation that may be passed by Congress or other legislative bodies or new regulations that may be issued by federal and other administrative agencies could significantly affect the sales, costs and profitability of our business. The chemical and ammunition industries are subject to legislative and regulatory actions, which could have a material adverse effect on our financial position or results of operations.

During the second and third quarters of 2009, a bill was introduced in the United States House of Representatives and the Senate, respectively, which, if enacted, would ban the production of chlor alkali products using mercury cell technology two years from the date it is enacted into law. On October 21, 2009, the House of Representatives Committee on Energy and Commerce passed a bill that would require chlor alkali producers using mercury cell technology to make a decision by June 30, 2012 as to whether to shutdown or convert these facilities. If the decision is to convert, the mercury cell plants would be required to be converted by June 30, 2015. If the decision is not to convert, the plants would be required to be shutdown by June 30, 2013. For this bill to become law it must be passed by the full House of Representatives and the full Senate. No additional action has been taken on this bill since October in the House of Representatives and no action has yet been taken by the Senate on its bill. We currently operate two facilities which utilize mercury cell technology totaling approximately 350,000 ECUs of capacity (approximately 18% of our capacity). We are closely monitoring the progress of these bills, but it is too soon to estimate the likelihood of enactment, and therefore to determine what impact there will be on us and the chlor alkali industry. We operate our mercury cell facilities in full compliance with all environmental rules and regulations.

Litigation and Claims—We are subject to litigation and other claims, which could cause us to incur significant expenses.

We are a defendant in a number of pending legal proceedings relating to our present and former operations. These include proceedings alleging injurious exposure of plaintiffs to various chemicals and other substances (including proceedings based on alleged exposures to asbestos). Frequently, such proceedings involve claims made by numerous plaintiffs against many defendants. However, because of the inherent uncertainties of litigation, we are unable to predict the outcome of these proceedings and therefore cannot determine whether the financial impact, if any, will be material to our financial position or results of operations.

Security and Chemicals Transportation—New regulations on the transportation of hazardous chemicals and/or the security of chemical manufacturing facilities and public policy changes related to transportation safety could result in significantly higher operating costs.

The chemical industry, including the chlor alkali industry, has proactively responded to the issues related to national security and environmental concerns by starting new initiatives relating to the security of chemicals industry facilities and the transportation of hazardous chemicals in the United States. Government at the local, state, and federal levels also has begun regulatory processes which could lead to new regulations that would impact the security of chemical plant locations and the transportation of hazardous chemicals. Our Chlor Alkali business could be adversely impacted by the cost of complying with any new regulations. Our business also could be adversely affected because of an incident at one of our facilities or while transporting product. The extent of the impact would depend on the requirements of future regulations and the nature of an incident, which are unknown at this time.

Production Hazards—Our facilities are subject to operating hazards, which may disrupt our business.

We are dependent upon the continued safe operation of our production facilities. Our production facilities are subject to hazards associated with the manufacture, handling, storage and transportation of chemical materials and products and ammunition, including leaks and ruptures, explosions, fires, inclement weather and natural disasters, unexpected utility disruptions or outages, unscheduled downtime and environmental hazards. From time to time in the past, we have had incidents that have temporarily shut down or otherwise disrupted our manufacturing, causing production delays and resulting in liability for workplace injuries and fatalities. Some of our products involve the manufacture and/or handling of a variety of explosive and flammable materials. Use of these products by our customers could also result in liability if an explosion, fire, spill or other accident were to occur. We cannot assure you that we will not experience these types of incidents in the future or that these incidents will not result in production delays or otherwise have a material adverse effect on our business, financial condition or results of operations.

Cost Control—Our profitability could be reduced if we continue to experience increasing raw material, utility, transportation or logistics costs, or if we fail to achieve our targeted cost reductions.

Our operating results and profitability are dependent upon our continued ability to control, and in some cases further reduce, our costs. If we are unable to do so, or if costs outside of our control, particularly our costs of raw materials, utilities, transportation and similar costs, increase beyond anticipated levels, our profitability will decline.

Credit Facilities—Weak industry conditions could affect our ability to comply with the financial maintenance covenants in our senior revolving credit facility and our Accounts Receivable Facility.

Our senior revolving credit facility and our Accounts Receivable Facility include certain financial maintenance covenants requiring us to not exceed a maximum leverage ratio and to maintain a minimum coverage ratio. Depending on the magnitude and duration of chlor alkali cyclical downturns, including deterioration in prices and volumes, there can be no assurance that we will continue to be in compliance with these ratios. If we failed to comply with either of these covenants in a future period and were not able to obtain waivers from the lenders thereunder, we would need to refinance our current senior revolving credit facility and Accounts Receivable Facility. However, there can be no assurance that such refinancing would be available to us on terms that would be acceptable to us or at all.

Pension Plans—The impact of declines in global equity and fixed income markets on asset values and any declines in interest rates used to value the liabilities in our pension plan may result in higher pension costs and the need to fund the pension plan in future years in material amounts.

In May 2007 and September 2006, we made voluntary pension plan contributions of $100.0 million and $80.0 million, respectively.

Under Accounting Standard Codification (ASC) 715 “Compensation–Retirement Benefits” (ASC 715), formerly Statement of Financial Accounting Standards (SFAS) No. 158, “Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans,” (SFAS No. 158), we recorded an after-tax charge of $27.3 million ($41.7 million pretax) to shareholders’ equity as of December 31, 2009 for our pension and other postretirement plans. This charge reflected a 50-basis point decrease in the plans discount rate, partially offset by the favorable performance on plan assets during 2009. In 2008, we recorded an after-tax charge of $99.4 million ($162.7 million pretax) to shareholders’ equity as of December 31, 2008 for our pension and other postretirement plans. This charge reflected the unfavorable performance on plan assets during 2008. In 2007, we recorded a $138.3 million after-tax credit ($226.6 million pretax) to shareholders’ equity as of December 31, 2007 for our pension and other postretirement plans. This credit reflected a 25-basis point increase in the plans’ discount rate, combined with an increase in the value of the plan assets from favorable plan performance and the $100.0 million contribution. The non-cash charges or credits to shareholders’ equity do not affect our ability to borrow under our senior revolving credit agreement.

During 2007, the asset allocation in the plan was adjusted to attempt to insulate the plan from discount rate risk and reduce the plan’s exposure to equity investments. Effective January 1, 2005, our defined benefit pension plan was closed to new salaried and certain non-bargained hourly employees. Subsequently, as new collective bargaining agreements were negotiated, by January 1, 2009, our defined benefit pension plan was closed to all our new union-represented employees. Effective January 1, 2008, we froze our defined benefit pension plan for salaried and certain non-bargained hourly workers and these employees began to participate in a defined contribution pension plan. In 2010, we expect pension income associated with the defined benefit pension plan to be similar compared to 2009.

The determinations of pension expense and pension funding are based on a variety of rules and regulations. Changes in these rules and regulations could impact the calculation of pension plan liabilities and the valuation of pension plan assets. They may also result in higher pension costs, additional financial statement disclosure, and accelerate the need to fully fund the pension plan. During the third quarter of 2006, the “Pension Protection Act of 2006” became law, amended by “The Worker, Retiree, and Employer Recovery Act,” during the fourth quarter of 2008. Among the stated objectives of the laws were the protection of both pension beneficiaries and the financial health of the Pension Benefit Guaranty Corporation (PBGC). To accomplish these objectives, the new laws required sponsors to fund defined benefit pension plans earlier than previous requirements and to pay increased PBGC premiums. Based on the combination of the asset allocation adjustment, the favorable asset performance in 2006, 2007 and 2009, the $100.0 million and $80.0 million voluntary contributions, and the benefits from the plan freeze, offset by the unfavorable performance on plan assets in 2008, we will not be required to make any cash contributions to the domestic defined benefit pension plan at least through 2010. We do have a small Canadian defined benefit pension plan to which we made $4.5 million of contributions in 2009 and we anticipate approximately $4 million of contributions in 2010. At December 31, 2009, the market value of assets in our defined benefit pension plans of $1,722.0 million exceeded the projected benefit obligation by $5.0 million.

In addition, the impact of declines in global equity and fixed income markets on asset values may result in higher pension costs and may increase and accelerate the need to fund the pension plan in future years. For example, holding all other assumptions constant, a 100-basis point decrease or increase in the assumed rate of return on plan assets would have decreased or increased, respectively, the 2009 defined benefit pension plan income by approximately $15.6 million.

Holding all other assumptions constant, a 50-basis point decrease in the discount rate used to calculate pension income for 2009 and the projected benefit obligation as of December 31, 2009 would have decreased pension income by $1.4 million and increased the projected benefit obligation by $82.0 million. A 50-basis point increase in the discount rate used to calculate pension income for 2009 and the projected benefit obligation as of December 31, 2009 would have increased pension income by $2.7 million and decreased the projected benefit obligation by $83.0 million.

Indebtedness—Our indebtedness could adversely affect our financial condition and limit our ability to grow and compete, which could prevent us from fulfilling our obligations under our indebtedness.

As of December 31, 2009, we had $398.4 million of indebtedness outstanding, including $1.4 million representing the fair value related to $26.6 million of interest rate swaps and $5.5 million representing the unrecognized gain related to $75 million of interest rate swaps at December 31, 2009. This outstanding indebtedness excludes our guarantee of $48.8 million of indebtedness of SunBelt. This does not include our $240.0 million senior revolving credit facility of which we had $219.6 million available on that date because we had issued $20.4 million of letters of credit or our $75 million accounts receivable securitization facility (Accounts Receivable Facility). As of December 31, 2009, our indebtedness represented 32.6% of our total capitalization. At December 31, 2009, none of our indebtedness was due within one year.

Our indebtedness could adversely affect our financial condition and limit our ability to fund working capital, capital expenditures and other general corporate purposes, to accommodate growth by reducing funds otherwise available for other corporate purposes, and to compete, which in turn could prevent us from fulfilling our obligations under our indebtedness. In addition, our indebtedness could make us more vulnerable to any continuing downturn in general economic conditions and reduce our ability to respond to changing business and economic conditions. Despite our level of indebtedness, the terms of our senior revolving credit facility, our Accounts Receivable Facility, and our existing indentures permit us to borrow additional money. If we borrow more money, the risks related to our indebtedness could increase.

Debt Service—We may not be able to generate sufficient cash to service our debt, which may require us to refinance our indebtedness or default on our scheduled debt payments.

Our ability to generate sufficient cash flow from operations to make scheduled payments on our debt depends on a range of economic, competitive and business factors, many of which are outside our control. We cannot assure you that our business will generate sufficient cash flow from operations. If we are unable to meet our expenses and debt obligations, we may need to refinance all or a portion of our indebtedness on or before maturity, sell assets or raise equity. We cannot assure you that we would be able to refinance any of our indebtedness, sell assets or raise equity on commercially reasonable terms or at all, which could cause us to default on our obligations and impair our liquidity. Our inability to generate sufficient cash flow to satisfy our debt obligations, or to refinance our obligations on commercially reasonable terms, would have an adverse effect on our business, financial condition and results of operations, as well as on our ability to satisfy our debt obligations. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations.” See Item 7A—“Quantitative and Qualitative Disclosures about Market Risk” and “Liquidity and Other Financing Arrangements.”

Credit and Capital Market Conditions—Adverse conditions in the credit and capital markets may limit or prevent our ability to borrow or raise capital.

While we believe we have facilities in place that should allow us to borrow funds as needed, adverse conditions in the credit and financial markets could prevent us from obtaining financing, if the need arises. Our ability to invest in our businesses and refinance maturing debt obligations could require access to the credit and capital markets and sufficient bank credit lines to support cash requirements. If we are unable to access the credit and capital markets, we could experience a material adverse effect on our financial position or results of operations.

Labor Matters—We cannot assure you that we can conclude future labor contracts or any other labor agreements without work stoppages.

Various labor unions represent a majority of our hourly-paid employees for collective bargaining purposes. The following labor contract is scheduled to expire in 2010:

Location		Number of Employees		Expiration Date
Henderson, NV (Chlor Alkali)		70		March 2010

Item 1B. UNRESOLVED STAFF COMMENTS

Not applicable.

Item 2. PROPERTIES

We have manufacturing sites at 13 separate locations in ten states, Canada and Australia. Most manufacturing sites are owned although a number of small sites are leased. We listed the locations at or from which our products and services are manufactured, distributed, or marketed in the tables set forth under the caption “Products and Services.”

We lease warehouses, terminals and distribution offices and space for executive and branch sales offices and service departments.

Item 3. LEGAL PROCEEDINGS

Saltville

We have completed all work in connection with remediation of mercury contamination at the site of our former mercury cell chlor alkali plant in Saltville, VA required to date. In mid-2003, the Trustees for natural resources in the North Fork Holston River, the Main Stem Holston River, and associated floodplains, located in Smyth and Washington Counties in Virginia and in Sullivan and Hawkins Counties in Tennessee notified us of, and invited our participation in, an assessment of alleged damages to natural resources resulting from the release of mercury. The Trustees also notified us that they have made a preliminary determination that we are potentially liable for natural resource damages in said rivers and floodplains. We have agreed to participate in the assessment. We and the Trustees have agreed to enter into discussions concerning a resolution of this matter. In light of the ongoing discussions and inherent uncertainties of the assessment, we cannot at this time determine whether the financial impact, if any, of this matter will be material to our financial position or results of operations. See “Environmental Matters” contained in Item 7—“Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

St. Gabriel, LA Mercury Vapor Emissions Release

Our subsidiary, Pioneer, discovered in October 2004 that the carbon-based system used to remove mercury from the hydrogen gas stream at the St. Gabriel, LA facility was not at that time sufficiently effective, resulting in mercury vapor emissions that were above the permit limits approved by the Louisiana Department of Environmental Quality (LDEQ). Pioneer immediately reduced the plant’s operating rate and, in late November 2004, completed the installation of the necessary equipment and made the other needed changes, and the plant resumed its normal operations. Pioneer’s emissions monitoring since that time confirmed that the air emissions are below the permit limits. In January 2005, the LDEQ issued a violation notice to Pioneer as a result of this mercury vapor emissions release. In December 2005, the LDEQ issued a penalty assessment of $0.4 million with respect to the notice of violation. Pioneer has administratively appealed the penalty assessment. Given the facts and circumstances, Pioneer requested that the LDEQ reconsider the penalty assessment.

Other

As part of the continuing environmental investigation by federal, state, and local governments of waste disposal sites, we have entered into a number of settlement agreements requiring us to participate in the investigation and cleanup of a number of sites. Under the terms of such settlements and related agreements, we may be required to manage or perform one or more elements of a site cleanup, or to manage the entire remediation activity for a number of parties, and subsequently seek recovery of some or all of such costs from other Potentially Responsible Parties (PRPs). In many cases, we do not know the ultimate costs of our settlement obligations at the time of entering into particular settlement agreements, and our liability accruals for our obligations under those agreements are often subject to significant management judgment on an ongoing basis. Those cost accruals are provided for in accordance with generally accepted accounting principles and our accounting policies set forth in the environmental matters section in Item 7—“Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

We, and our subsidiaries, are defendants in various other legal actions (including proceedings based on alleged exposures to asbestos) incidental to our past and current business activities. While we believe that none of these legal actions will materially adversely affect our financial position, in light of the inherent uncertainties of litigation, we cannot at this time determine whether the financial impact, if any, of these matters will be material to our results of operations.

Item 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

We did not submit any matter to a vote of security holders during the three months ended December 31, 2009.

On April 30, 1998, we announced a share repurchase program approved by our board of directors for the purchase of up to 5 million shares of common stock. Through December 31, 2009, 4,845,924 shares had been repurchased, and 154,076 shares remain available for purchase under that program, which has no termination date.

Performance Graph

This graph compares the total shareholder return on our common stock with the total return on the (i) Standard and Poor’s 1000 Index (the “S&P 1000”) and (ii) the Peer Group. Our Peer Group is comprised of Georgia Gulf Corporation, Occidental Petroleum Corporation, Alliant Techsystems, PPG Industries, Inc., The Dow Chemical Company and Westlake Chemical Corporation.

Data is for the five-year period from December 31, 2004 through December 31, 2009. The cumulative return includes reinvestment of dividends. The Peer Group is weighted in accordance with market capitalization (closing stock price multiplied by the number of shares outstanding) as of the beginning of each of the five years covered by the performance graph. We calculated the weighted return for each year by multiplying (a) the percentage that each corporation’s market capitalization represented of the total market capitalization for all corporations in the Peer Group for such year by (b) the total shareholder return for that corporation for such year.

Item 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

BUSINESS BACKGROUND

The Metals business was classified as discontinued operations during 2007 and was excluded from the segment results for all periods presented. As a result, our manufacturing operations are concentrated in two business segments: Chlor Alkali Products and Winchester. Both are capital intensive manufacturing businesses with operating rates closely tied to the general economy. Each segment has a commodity element to it, and therefore, our ability to influence pricing is quite limited on the portion of the segment’s business that is strictly commodity. Our Chlor Alkali Products business is a commodity business where all supplier products are similar and price is the major supplier selection criterion. We have little or no ability to influence prices in this large, global commodity market. Cyclical price swings, driven by changes in supply/demand, can be abrupt and significant and, given capacity in our Chlor Alkali Products business, can lead to very significant changes in our overall profitability. Winchester also has a commodity element to its business, but a majority of Winchester ammunition is sold as a branded consumer product where there are opportunities to differentiate certain offerings through innovative new product development and enhanced product performance. While competitive pricing versus other branded ammunition products is important, it is not the only factor in product selection.

RECENT DEVELOPMENTS AND HIGHLIGHTS

2009 Year

In 2009, Chlor Alkali Products’ segment income was $125.4 million, a decline of 62% compared with the prior year. Chlor Alkali Products continued to experience the weak product demand that began in the fourth quarter of 2008. Volumes for chlorine and caustic soda decreased 22% compared to 2008. Volumes for bleach, which accounted for approximately 12% of Chlor Alkali Products’ sales, increased 17% compared to 2008. Operating rates in Chlor Alkali Products for 2009 and 2008 were 70% and 82%, respectively. These operating rates assume that 100% of our demonstrated capacity was available for use. The capacity of our St. Gabriel, LA facility had been shutdown since late November 2008 and the facility was not available for use until the conversion and expansion project was completed in the fourth quarter of 2009. In addition, in response to low levels of customer demand for chlorine and caustic soda, an additional 5% of our chlorine and caustic soda capacity has been idled by us. After taking these capacity reduction actions into consideration, our effective operating rate for 2009 was 78%.

Our 2009 ECU netbacks of $520 were 18% lower than the 2008 netbacks of $635, reflecting the changes in the pricing dynamics in North America. During 2008, North American demand for caustic soda remained strong, while supply continued to be constrained by the weakness in chlorine demand. This resulted in a significant supply and demand imbalance for caustic soda in North America, which resulted in record caustic soda pricing. The result was a record ECU netback, in our system, in the first quarter of 2009 of approximately $765. Beginning late in the fourth quarter of 2008 and continuing through 2009, demand for caustic soda weakened significantly, and fell below the demand for chlorine. This created excess supply in North America, which has caused caustic soda prices to fall. The over supply of caustic soda caused industry operating rates to be constrained, which resulted in chlorine price increase announcements of $300 per ton during the second quarter of 2009. Caustic soda prices declined precipitously in the second quarter of 2009 and these declines continued into the third quarter of 2009. During the third quarter of 2009, chlorine and caustic soda demand became more balanced eliminating the oversupply of caustic soda. We began realizing increases in chlorine prices in the third quarter of 2009 with most of the improvement in the fourth quarter of 2009. We believe that ECU netbacks, in our system, have bottomed out in the third quarter of 2009. During the fourth quarter of 2009, as caustic soda demand improved, chlorine production declined due to seasonally weaker demand. This resulted in a supply and demand imbalance for caustic soda in North America. As a result of this imbalance, in December 2009, a $75 per ton caustic soda price increase was announced. We expect to begin realizing this price increase in caustic soda in the second quarter of 2010.

Winchester segment income of $68.6 million in 2009, which represented the highest level of segment income in at least the last two decades, improved 110% compared to the prior year segment income of $32.6 million. Winchester continues to experience the above normal levels of demand that began around the November 2008 presidential election. The increase in demand has been across the majority of Winchester’s product offerings, including rifle, pistol and rimfire ammunition. On a volume basis, Winchester’s unit shipments increased 14% in 2009 compared to 2008, which was driven by the higher level of commercial sales. Winchester’s results reflected the impact of increased volumes and higher selling prices, and lower commodity and other material costs.

Income from continuing operations before taxes for 2009 included $82.1 million of recoveries from third parties for environmental costs incurred and expensed in prior periods.

On August 19, 2009, we sold $150.0 million of 8.875% Senior Notes (2019 Notes) with a maturity date of August 15, 2019. The 2019 Notes were issued at 99.19% of par value, providing a yield to maturity to investors of 9.0%. Interest will be paid semi-annually beginning on February 15, 2010. Proceeds of $145.5 million, after expenses of $3.3 million, from the 2019 Notes will be used to further strengthen our long-term liquidity given uncertain economic times.

During the fourth quarter of 2009, we completed a conversion and expansion project at our St. Gabriel, LA facility and initiated production. This project increased capacity at this location from 197,000 ECUs to 246,000 ECUs and will significantly reduce the site’s manufacturing costs. Our capital spending included $69.6 million and $87.2 million for the St. Gabriel, LA facility conversion and expansion project in 2009 and 2008, respectively.

2008 Year

In 2008, Chlor Alkali Products had record segment income of $328.3 million, an improvement of 38% compared with 2007. This improvement reflects the combination of the full year contributions from the Pioneer acquisition of $72.7 million, including synergies, and improved pricing of $108.4 million. These were partially offset by the effect from lower chlorine and caustic soda volumes of $46.7 million. Operating rates in our Chlor Alkali Products business were 82% for 2008, which were negatively impacted during the fourth quarter of 2008 by lower levels of demand from all major customer groups, and by hurricane-related outages at our St. Gabriel, LA facility and our SunBelt joint venture during the third quarter of 2008. In response to the low level of demand during the fourth quarter of 2008, we announced that the St. Gabriel, LA facility, which was shutdown for scheduled maintenance in late November 2008, would not resume operations until the current conversion and expansion project was completed. The project was completed in the fourth quarter of 2009. The St. Gabriel, LA facility represents approximately 10% of our chlorine and caustic soda capacity.

During the first three quarters of 2008, North American demand for caustic soda remained strong. In addition, caustic soda supply was constrained by the weakness in chlorine demand, which caused operating rates to be reduced. This created an imbalance between caustic soda supply and demand. This imbalance, combined with increased freight and energy costs, resulted in our achieving record levels of caustic soda pricing. During the fourth quarter of 2008, North American caustic soda demand weakened but less than the decline in chlorine demand. This caused the caustic soda supply and demand imbalance to continue, which continued to support record levels of caustic soda prices.

On March 12, 2008, we announced that, in connection with our plans to streamline Chlor Alkali Products manufacturing operations in Canada in order to serve our customer base in a more cost effective manner, we would close the acquired Dalhousie, New Brunswick, Canada chlorine, caustic soda, sodium chlorate, and bleach operations. We substantially completed the closure of the Dalhousie facility by June 30, 2008. We expect to incur cash expenditures of $2.5 million associated with the shutdown, which were previously included in current liabilities on the Pioneer acquisition balance sheet. We have paid $2.2 million of costs associated with this shutdown as of December 31, 2009. This action is expected to generate $8 million to $10 million of annual pretax savings.

Winchester segment income was $32.6 million in 2008, which represented record earnings for the Winchester business, an increase of 23% compared with 2007. Winchester’s results for 2008 reflected the combination of improved pricing and increased law enforcement volumes which more than offset higher commodity, material and manufacturing costs.

In 2008, other income (expense) included an impairment charge of the full value of a $26.6 million investment in corporate debt securities. On October 1, 2008, the issuer of these debt securities announced it would cease trading and appoint a receiver as a result of financial market turmoil. The decline in the market value of the assets supporting these debt securities negatively impacted the liquidity of the issuer. During the third quarter of 2008, we determined that these debt securities had no fair market value due to the actions taken by the issuer, turmoil in the financial markets, the lack of liquidity of the issuer, and the lack of trading in these debt securities. We are currently unable to utilize the capital loss resulting from the impairment of these corporate debt securities; therefore, no tax benefit has been recognized for the impairment loss.

In 2008, the domestic defined benefit pension plan’s investment portfolio declined by approximately 1%. The decline reflected the weakness in the domestic and international equity markets and increases in interest rate spreads, which reduced the value of certain corporate fixed income investments. The 2008 pension plan’s investment performance reflects the actions taken in 2007 to reduce the defined benefit pension plan’s exposure to equity investments and increase its exposure to fixed income investments. During the same period, interest rates on corporate bonds, used to determine the defined benefit pension plan’s liability discount rate, fluctuated dramatically during the year but ended comparable with the levels at December 31, 2007, which resulted in no change to the discount rate for 2008. We recorded an after-tax charge of $99.4 million ($162.7 million pretax) to shareholders’ equity as of December 31, 2008 for our pension and other postretirement plans, which reduced the over funded position in our pension plan that existed at December 31, 2007. This charge reflected the unfavorable performance on pension plan assets and the unchanged discount rate during 2008.

2007 Year

Discontinued Operations

In 2001, the industry in which the Metals business operates experienced a 25% decline in volumes that created over capacity in the marketplace, which reduced our financial returns in the Metals business. Volumes did not return to pre-2001 levels. Since 2001, we had undertaken a number of restructuring and downsizing actions, including multiple plant closures. The benefits of these actions were more than offset by the escalation of both energy and commodity metal prices, specifically copper, zinc, and nickel. As a result, we were unable to realize acceptable returns in the business. During the second half of 2006 and first half of 2007, we evaluated a number of strategic alternatives for the Metals business, and we made the decision in mid-2007 to engage Goldman, Sachs & Co. to conduct a formal strategic evaluation process, including the alternative of selling the business. The sale of Metals provides us with the financial flexibility to pursue investments in areas where we can earn the best returns.

On October 15, 2007, we announced we entered into a definitive agreement to sell the Metals business to Global for $400 million, payable in cash. The price received was subject to a customary working capital adjustment. The sale was subject to Hart-Scott-Rodino Antitrust Improvement Act clearance, but not shareholder approval. The transaction closed on November 19, 2007. Based on the Metals assets held for sale, we recognized a pretax loss of $160.0 million partially offset by a $21.0 million income tax benefit, resulting in a net loss on disposal of discontinued operations of $139.0 million for 2007. The loss on disposal of discontinued operations included a pension curtailment charge of $6.9 million, other postretirement benefits curtailment credit of $1.1 million and transaction fees of $24.6 million. The final loss recognized related to this transaction did not change upon the final determination of the value of working capital in the business. The loss on the disposal, which included transaction costs, reflected a book value of the Metals business of approximately $564 million and a tax basis of approximately $396 million. The difference between the book and tax values of the business reflected primarily goodwill of $75.8 million and intangibles of $10.4 million. Based on the final working capital adjustment, we received net cash proceeds from the transaction of $380.8 million, which was in addition to the $98.1 million of after-tax cash flow realized from the operation of Metals during 2007.

In April 2008, we and Global entered into binding arbitration regarding the final working capital adjustment. The arbitration was concluded in 2009 and resulted in a payment of $20.6 million, which was consistent with the estimated working capital adjustment we anticipated from the transaction.

The Metals business was a reportable segment comprised of principal manufacturing facilities in East Alton, IL and Montpelier, OH. Metals produced and distributed copper and copper alloy sheet, strip, foil, rod, welded tube, fabricated parts, and stainless steel and aluminum strip. Sales for the Metals business were $1,891.7 million for the period of our ownership in 2007. The Metals business sales included commodity metal price changes that are primarily a pass-through. Intersegment sales of $81.4 million for the period of our ownership in 2007, representing the sale of ammunition cartridge case cups to Winchester from Metals, at prices that approximate market, have been eliminated from Metals sales. In conjunction with the sale of the Metals business, Winchester agreed to purchase the majority of its ammunition cartridge case cups and copper-based strip requirements from Global under a multi-year agreement with pricing, terms, and conditions which approximate market. The Metals business employed approximately 2,900 hourly and salaried employees. The results of operations from the Metals business have been presented as discontinued operations for all periods presented.

In conjunction with the sale of the Metals business, we retained certain assets and liabilities including certain assets co-located with our Winchester business in East Alton, IL, assets and liabilities associated with former Metals manufacturing locations, pension assets and pension and postretirement healthcare and life insurance liabilities associated with Metals employees for service earned through the date of sale, and certain environmental obligations existing at the date of closing associated with current and past Metals manufacturing operations and waste disposal sites.

Pioneer Acquisition

On August 31, 2007, we acquired Pioneer, a manufacturer of chlorine, caustic soda, bleach, sodium chlorate, and hydrochloric acid. Pioneer owned and operated four chlor-alkali plants and several bleach manufacturing facilities in North America. Under the merger agreement, each share of Pioneer common stock was converted into the right to receive $35.00 in cash, without interest. The aggregate purchase price for all of Pioneer’s outstanding shares of common stock, together with the aggregate payment due to holders of options to purchase shares of common stock of Pioneer, was $426.1 million, which includes direct fees and expenses. We financed the merger with cash and $110.0 million of borrowings against our Accounts Receivable Facility. At the date of acquisition, Pioneer had cash and cash equivalents of $126.4 million. We assumed $120.0 million of Pioneer’s convertible debt which was redeemed in the fourth quarter of 2007 and January 2008. We paid a conversion premium of $25.8 million on the Pioneer convertible debt.

For 2008 and the last four months of 2007, Pioneer sales were $552.7 million and $183.6 million, respectively, and segment income was $101.9 million and $29.2 million, respectively, which were included in our Chlor Alkali Products segment results.

Between August 2007 and December 2008, Chlor Alkali Products segment earnings included approximately $47 million of realized cost savings from integrating the Pioneer operations and our operations . The ability to optimize freight costs has been a key synergy realized as part of the Pioneer acquisition. In 2007 and 2008, we identified and implemented changes in ship-to and ship-from of both operations’ locations that have reduced annual chlorine ton miles shipped by approximately 5%. The opportunity to rationalize selling and administration costs was also a significant cost savings realized as part of the Pioneer acquisition. During the first quarter of 2008, the Pioneer corporate office in Houston was closed, the space was subleased, and all of those activities were consolidated into our existing functions and facilities.

Financing

In August 2007, we entered into a $35 million letter of credit facility to assume the various Pioneer letters of credit issued principally to support the acquisition of materials for the St. Gabriel, LA facility conversion and expansion project.

On June 26, 2007, we entered into the $100 million 364-day revolving credit facility ($100 million Credit Facility) and the $150 million 364-day revolving credit facility ($150 million Credit Facility). According to their terms, the $100 million Credit Facility matured on the earlier of June 24, 2008 or upon an increase in the lending commitments under our existing senior revolving credit facility and the establishment of an accounts receivable securitization facility, and the $150 million Credit Facility would have matured on June 24, 2008. In the fourth quarter of 2007, the $100 million Credit Facility expired as all conditions for early termination were met and the $150 million Credit Facility was terminated as we no longer needed the credit commitment.

On July 25, 2007, we established a $250 million, 364-day Accounts Receivable Facility, renewable annually for five years, which expires in July 2012. As a result of the sale of Metals, the Accounts Receivable Facility was reduced from $250 million to $100 million. In July 2008, the Accounts Receivable Facility was further reduced from $100 million to $75 million. The $75 million Accounts Receivable Facility provides for the sale of our eligible trade receivables to a third party conduit through a wholly-owned, bankruptcy-remote, special purpose entity that is consolidated for financial statement purposes. The Accounts Receivable Facility contains specific covenants relating to the ability of the lender to obtain or maintain a first priority lien on the receivables. In addition, the Accounts Receivable Facility incorporates the leverage and coverage covenants that are contained in the senior revolving credit facility.

CHLOR ALKALI PRODUCTS PRICING

In accordance with industry practice, we compare ECU prices on a netback basis, reporting and analyzing prices net of the cost of transporting the products to customers to allow for a comparable means of price comparisons between periods and with respect to our competitors. For purposes of determining our ECU netback, we use prices that we realize as a result of sales of chlorine and caustic soda to our customers, and we do not include the value of chlorine and caustic soda that is incorporated in other products that we manufacture and sell.

Quarterly and annual average ECU netbacks, excluding SunBelt, for 2009, 2008 and 2007 were as follows, which includes Pioneer ECU netbacks subsequent to August 31, 2007:

	2009		2008		2007
First quarter	$	765	$	580	$	500
Second quarter		585		590		510
Third quarter		375		660		550
Fourth quarter		425		740		555
Annual average		520		635		535

PENSION AND POSTRETIREMENT BENEFITS

In October 2007, we announced that we were freezing our domestic defined benefit pension plan for salaried and certain non-bargained hourly employees. Affected employees were eligible to accrue pension benefits through December 31, 2007, but are not accruing any additional benefits under the plan after that date. Employee service after December 31, 2007 does count toward meeting the vesting requirements for such pension benefits and the eligibility requirements for commencing a pension benefit, but not toward the calculation of the pension benefit amount. Compensation earned after December 31, 2007 similarly does not count toward the determination of the pension benefit amounts under the defined benefit pension plan. In lieu of continuing pension benefit accruals for the affected employees under the pension plan, starting in 2008, we provide a contribution to an individual retirement contribution account maintained with the Contributing Employee Ownership Plan (CEOP) equal to 5% of the employee’s eligible compensation if such employee is less than age 45, and 7.5% of the employee’s eligible compensation if such employee is age 45 or older. Freezing the domestic defined benefit pension plan for salaried and certain non-bargained hourly employees was accounted for as a curtailment under ASC 715, formerly SFAS No. 88, “Employer’s Accounting for Settlements and Curtailments of Defined Benefit Pension Plan and for Termination Benefits” (SFAS No. 88). As a result of freezing the domestic defined benefit pension plan, we recorded a curtailment charge of $1.9 million for the defined benefit pension plan and a corresponding curtailment credit of $1.9 million for the non-qualified pension plan in 2007.

We account for our defined benefit pension plans and non-pension postretirement benefit plans using actuarial models required by ASC 715, formerly SFAS No. 87, “Employers’ Accounting for Pensions” (SFAS No. 87) and SFAS No. 106 "Employers' Accounting for Postretirement Benefits Other than Pension," (SFAS No. 106), respectively. This model uses an attribution approach that generally spreads the financial impact of changes to the plan and actuarial assumptions over a period of time. Changes in liability due to changes in actuarial assumptions such as discount rate, rate of compensation increases and mortality, as well as annual deviations between what was assumed and what was experienced by the plan are treated as gains or losses. The principle underlying the required attribution approach is that employees render service over their average remaining service lives on a relatively smooth basis and, therefore, the accounting for benefits earned under the pension or non-pension postretirement benefits plans should follow the same relatively smooth pattern. With the closure of our defined benefit pension plan to new entrants, the freezing of our domestic defined benefit pension plan for salaried and certain non-bargained hourly employees that became effective January 1, 2008 and the sale of the Metals business, substantially all defined benefit pension plan participants beginning in 2008 were inactive; therefore, actuarial gains and losses are now being amortized based upon the remaining life expectancy of the inactive plan participants rather than the future service period of the active participants, which was the amortization period used prior to 2008. For the years ended December 31, 2009 and 2008, the average remaining life expectancy of the inactive participants in the defined benefit pension plan was 19 years.

During the third quarter of 2006, the “Pension Protection Act of 2006”, amended by “The Worker, Retiree, and Employer Recovery Act,” during the fourth quarter of 2008, became law. Among the stated objectives of the laws are the protection of both pension beneficiaries and the financial health of the PBGC. To accomplish these objectives, the new laws require sponsors to fund defined benefit pension plans earlier than previous requirements and to pay increased PBGC premiums. The laws require defined benefit pension plans to be fully funded in 2011. In September 2006, we made a voluntary pension plan contribution of $80.0 million and in May 2007, we made an additional $100.0 million voluntary contribution to our defined benefit pension plan. During 2007, the asset allocation in the plan was adjusted to attempt to insulate the plan from discount rate risk and reduce the plan’s exposure to equity investments. Based on the combination of these actions and favorable asset performance in 2006, 2007 and 2009 offset by the unfavorable performance on plan assets in 2008, we will not be required to make any cash contributions to the domestic defined benefit pension plan at least through 2010. We do have a small Canadian defined benefit pension plan to which we made $4.5 million of contributions in 2009 and we anticipate approximately $4 million of contributions in 2010. At December 31, 2009, the market value of assets in our defined benefit pension plans of $1,722.0 million exceeded the projected benefit obligation by $5.0 million.

Under ASC 715, formerly SFAS No. 158, we recorded an after-tax charge of $27.3 million ($41.7 million pretax) to shareholders’ equity as of December 31, 2009 for our pension and other postretirement plans. This charge reflected a 50-basis point decrease in the plans’ discount rate, partially offset by the favorable performance on plan assets during 2009. In 2008, we recorded an after-tax charge of $99.4 million ($162.7 million pretax) to shareholders’ equity as of December 31, 2008 for our pension and other postretirement plans. This charge reflected the unfavorable performance on plan assets during 2008. In 2007, we recorded a $138.3 million after-tax credit ($226.6 million pretax) to shareholders’ equity as of December 31, 2007 for our pension and other postretirement plans. This credit reflected a 25-basis point increase in the plans’ discount rate, combined with an increase in the value of the plan assets from favorable plan performance and the $100.0 million contribution. The non-cash credits or charges to shareholders’ equity do not affect our ability to borrow under our senior revolving credit agreement.

Components of net periodic benefit (income) costs were:

Pension benefits	$	(16.7	)	$	(7.6	)	$	33.5
Other postretirement benefits		7.3			8.5			10.8

In 2008, we recorded curtailment charges of $4.1 million associated with the transition of a portion of our East Alton, IL Winchester hourly workforce and our McIntosh, AL Chlor Alkali hourly workforce from a defined benefit pension plan to a defined contribution pension plan. In 2007, we recorded a defined benefit pension curtailment charge of $6.9 million and other postretirement benefits curtailment credit of $1.1 million related to the sale of the Metals business, which were included in the loss on disposal of discontinued operations. Also during 2007, we recorded a curtailment charge of $0.5 million resulting from the conversion of a portion of the Metals hourly workforce from a defined benefit pension plan to a defined contribution pension plan. This curtailment charge was included in income from discontinued operations.

After giving effect to the changes in curtailment charges and credits, the decrease in 2008 net periodic pension expense from 2007 was due to the favorable impact of the $100 million voluntary contribution made in May 2007, the favorable 2007 investment returns, a 25-basis point increase in the liability discount rate in 2007, the impact of the plan freeze for salaried and certain non-bargained hourly employees that became effective January 1, 2008, and an increase in the amortization period for actuarial losses.

The service cost and the amortization of prior service cost components of pension expense related to employees of the operating segments are allocated to the operating segments based on their respective estimated census data. Therefore, the allocated portion of net periodic benefit costs for the Metals business of $7.9 million for the period of our ownership in 2007 was included in income from discontinued operations. The portion of other postretirement benefit costs for the Metals business employees of $4.4 million for the period of our ownership in 2007 was also included in income from discontinued operations.

2009 Compared to 2008

Our total sales for 2009 were $1,531.5 million compared to $1,764.5 million last year, a decrease of $233.0 million, or 13%. Chlor Alkali Products’ sales decreased by $311.6 million, or 24%, primarily due to decreased shipment volumes and lower ECU prices. Our ECU netbacks, excluding SunBelt, decreased 18% compared to last year. Winchester sales increased by $78.6 million, or 16%, from 2008 primarily due to increased volumes.

Gross margin decreased $78.5 million, or 20%, from 2008, due to decreased Chlor Alkali gross margin resulting from lower volumes and decreased ECU netbacks, partially offset by improved Winchester gross margin resulting from higher volumes and lower commodity and other material costs. The 2009 gross margin was positively impacted by recoveries from third parties for environmental costs incurred and expensed in prior periods of $82.1 million. Gross margin as a percentage of sales decreased to 20% in 2009 from 22% in 2008.

Selling and administration expenses in 2009 decreased $2.0 million, or 1%, from 2008, primarily due to lower non-income taxes of $5.3 million, primarily due to a favorable resolution of a Canadian capital tax matter, lower recruiting and relocation charges of $4.3 million, and decreased management incentive compensation expense of $2.5 million, which includes mark-to-market adjustments on stock-based compensation, partially offset by a higher level of legal and legal-related settlement expenses of $3.6 million, which included costs for recovery actions for environmental costs previously incurred and expensed, a higher provision for doubtful customer accounts receivable of $2.6 million related to a deterioration in customer credit, increased consulting and professional fees of $2.3 million and higher salary and benefit costs of $1.6 million. Selling and administration expenses as a percentage of sales were 9% in 2009 and 8% in 2008.

Other operating income in 2009 increased by $7.9 million from 2008. Other operating income for 2009 included gains of $6.5 million on the disposition of property, plant, and equipment compared to a loss of $0.7 million for 2008. The 2009 gains were primarily associated with sales of real estate and dispositions of assets associated with the St. Gabriel, LA facility conversion and expansion project. Other operating income for 2009 also included a gain of $0.8 million for the sale of other assets.

The earnings of non-consolidated affiliates were $37.7 million for 2009, a decrease of $1.7 million from 2008, primarily due to lower ECU prices at SunBelt, partially offset by increased earnings at our bleach joint venture.

Interest expense decreased by $1.7 million, or 13%, in 2009 primarily due to an increase of $4.7 million in capitalized interest associated with our St. Gabriel, LA facility conversion and expansion project and a major maintenance capital project at our McIntosh, AL facility, partially offset by a higher level of outstanding debt.

Interest income decreased by $5.1 million, or 82%, in 2009 primarily due to lower short-term interest rates.

The effective tax rate for 2009 included a $2.8 million reduction in expense primarily associated with the finalization of the 2008 income tax returns, which resulted in lower state tax expense, and a $3.2 million reduction in expense primarily associated with the expiration of statutes of limitation in domestic and foreign jurisdictions. After giving consideration to these two items of $6.0 million, the effective tax rate for 2009 of 38.2%, was higher than the 35% U.S. federal statutory rate primarily due to state income taxes, which were offset in part by the utilization of certain state tax credits. The effective tax rate for 2008 included expense of $10.4 million for a valuation allowance required against the deferred tax benefit resulting from the $26.6 million capital loss carryforward generated from the impairment of corporate debt securities. The effective tax rate for 2008 also included a $2.1 million reduction in expense primarily associated with the finalization of the 2007 income tax returns, which resulted in an increased benefit for the domestic manufacturing deduction. After giving consideration to these two items of $8.3 million, the effective tax rate for 2008 of 35.5% was higher than the 35% U.S. federal statutory rate primarily due to state income taxes, which were offset in part by the benefit of the domestic manufacturing deduction and the utilization of certain state tax credits.

2008 Compared to 2007

For 2008, total company sales were $1,764.5 million compared with $1,276.8 million in 2007, an increase of $487.7 million, or 38%. Chlor Alkali Products sales increased by $430.3 million, or 51%, primarily due to the inclusion of a full year of Pioneer sales in 2008 compared with four months in 2007 and higher ECU prices. The acquisition of Pioneer contributed to an increase in 2008 sales of $369.1 million compared to 2007. Winchester sales increased by $57.4 million, or 13%, from 2007 primarily due to increased selling prices and improved law enforcement volumes.

Gross margin increased $146.0 million, or 61%, from 2007, as a result of improved Chlor Alkali Products gross margin, primarily due to the contribution from Pioneer, and improved Winchester gross margin from higher selling prices. Gross margin was also positively impacted by decreased environmental costs in 2008 of $10.2 million primarily associated with a charge in 2007 related to costs at a former waste disposal site based on revised remediation estimates resulting from negotiations with a government agency and the reduction in defined benefit pension expense of $13.7 million, which was partially offset by an increase in defined contribution pension expense of $7.6 million. Gross margin as a percentage of sales increased to 22% in 2008 from 19% in 2007.

Selling and administration expenses as a percentage of sales were 8% in 2008 and 10% in 2007. Selling and administration expenses in 2008 were $8.1 million higher than 2007 primarily due to expenses associated with the acquired Pioneer operations, net of synergies of $10.5 million, a higher provision for doubtful customer accounts receivable of $3.0 million, increased stock-based compensation expense of $2.3 million, primarily resulting from mark-to-market adjustments, higher consulting costs of $1.3 million and increased salary and benefit costs of $1.4 million. These increases were partially offset by decreased defined benefit pension expense of $12.1 million, offset by increased defined contribution pension expense of $1.0 million.

Other operating income for 2008 included $1.0 million for a portion of a 2007 gain realized on an intangible asset sale in Chlor Alkali Products, which is recognized ratably through 2012, $0.9 million for a portion of a gain realized on the sale of equipment, which is recognized ratably through June 2009, and $0.2 million of a gain on the disposition of land associated with a former manufacturing facility. These gains were partially offset by a loss of $0.9 million on the disposition of property, plant and equipment. Other operating income for 2007 included the receipt of a $1.3 million contingent payment associated with a 1995 divestiture and $0.6 million for a portion of a 2007 gain realized on an intangible asset sale in Chlor Alkali Products.

The earnings of non-consolidated affiliates were $39.4 million for 2008, a decrease of $6.6 million from 2007. Lower volumes at SunBelt, due to the impact of hurricane-related outages and other force majeure events at one of its chlorine customers, were partially offset by higher ECU prices.

Interest expense decreased by $8.8 million, or 40%, in 2008, primarily due to a lower level of outstanding debt and capitalization of $5.0 million of interest in 2008 associated with our St. Gabriel, LA facility conversion and expansion project and a major maintenance capital project at our McIntosh, AL facility.

Interest income decreased by $5.4 million, or 47%, in 2008 primarily due to lower short-term interest rates.

Other income (expense) for 2008 included an impairment charge of the full value of a $26.6 million investment in corporate debt securities.

The effective tax rate for continuing operations for 2008 included expense of $10.4 million for a valuation allowance required against the deferred tax benefit generated from the impairment of corporate debt securities. As we are currently unable to utilize the capital loss resulting from the impairment of the $26.6 million of corporate debt securities, no tax benefit was recognized during 2008 for the impairment loss. Additionally, the effective tax rate for continuing operations for 2008 included a $2.1 million reduction in expense primarily associated with the finalization of the 2007 income tax returns which resulted in an increased benefit for the domestic manufacturing deduction. The effective tax rate for continuing operations for 2008 of 35.5%, which was increased by the effect of these two items of $8.3 million, was higher than the 35% U.S. federal statutory rate primarily due to state income taxes, which were offset in part by the benefit of the domestic manufacturing deduction and the utilization of certain state tax credits. The effective tax rate for continuing operations for 2007 of 33.1% was lower than the 35% U.S. federal statutory rate primarily due to the benefit of the domestic manufacturing deduction and the utilization of certain state tax credits, offset in part by state income taxes and income in certain foreign jurisdictions being taxed at higher rates.

SEGMENT RESULTS

We define segment results as income (loss) from continuing operations before interest expense, interest income, other income (expense), and income taxes and include the results of non-consolidated affiliates. Consistent with the guidance in ASC 280 “Segment Reporting” (ASC 280), formerly SFAS No. 131, “Disclosures About Segments of an Enterprise and Related Information,” (SFAS No. 131), we have determined it is appropriate to include the operating results of non-consolidated affiliates in the relevant segment financial results. Our management considers SunBelt to be an integral component of the Chlor Alkali Products segment. They are engaged in the same business activity as the segment, including joint or overlapping marketing, management, and manufacturing functions.

(1)

Earnings of non-consolidated affiliates are included in the Chlor Alkali Products segment results consistent with management’s monitoring of the operating segment. The earnings from non-consolidated affiliates were $37.7 million, $39.4 million, and $46.0 million for the years ended 2009, 2008 and 2007, respectively.

(2)

The service cost and the amortization of prior service cost components of pension expense related to the employees of the operating segments are allocated to the operating segments based on their respective estimated census data. All other components of pension costs are included in corporate/other and include items such as the expected return on plan assets, interest cost and recognized actuarial gains and losses. Pension income (expense) for the year ended December 31, 2008 included curtailment charges of $4.1 million associated with the transition of a portion of our East Alton, IL Winchester hourly workforce and our McIntosh, AL Chlor Alkali hourly workforce from a defined benefit pension plan to a defined contribution pension plan.

(3)	Environmental income (expense) in 2009 included $82.1 million of recoveries from third parties for costs incurred and expensed in prior periods. Environmental income (expense) is included in cost of goods sold in the consolidated statements of operations.

(4)	Other operating income for 2009 included a $3.7 million gain on the sale of land, a $1.2 million gain on the disposition of a former manufacturing facility and $1.6 million of gains on the disposal of assets primarily associated with the St. Gabriel, LA conversion and expansion project.

(5)	Interest expense was reduced by capitalized interest of $9.7 million, $5.0 million and $0.2 million for the years ended 2009, 2008 and 2007, respectively.

(6)

Other income (expense) in 2008 included an impairment charge of the full value of a $26.6 million investment in corporate debt securities. We are currently unable to utilize the capital loss resulting from the impairment of these corporate debt securities; therefore, no tax benefit has been recognized for the impairment loss.

Chlor Alkali Products

2009 Compared to 2008

Chlor Alkali Products’ sales for 2009 were $963.8 million compared to $1,275.4 million for 2008, a decrease of $311.6 million, or 24%. The sales decrease was primarily due to lower chlorine and caustic soda volumes of 22%, and lower ECU pricing, which decreased 18% from 2008. Volumes for bleach, which accounted for approximately 12% of Chlor Alkali Products’ sales, increased 17% compared to 2008. Our ECU netbacks, excluding SunBelt, were approximately $520 compared to approximately $635 for 2008. Freight costs included in the ECU netback increased 9% for 2009 compared to 2008. Our operating rate for 2009 was 70%, compared to our operating rate of 82% for 2008. The lower operating rate for 2009 was the result of lower caustic soda and chlorine demand.

Chlor Alkali posted segment income of $125.4 million for 2009 compared to $328.3 million for 2008, a decrease of $202.9 million, or 62%. Chlor Alkali segment income was lower primarily due to lower ECU netbacks ($126.9 million), decreased volumes ($69.1 million), higher operating costs ($5.2 million), and lower earnings of non-consolidated affiliates ($1.7 million). The lower earnings of non-consolidated affiliates primarily resulted from lower ECU prices at SunBelt, partially offset by increased earnings at our bleach joint venture. The operating results from SunBelt included interest expense of $4.0 million and $4.4 million in 2009 and 2008, respectively, on the SunBelt Notes.

2008 Compared to 2007

Chlor Alkali Products’ sales for 2008 were $1,275.4 million compared to $845.1 million for 2007, an increase of $430.3 million, or 51%. Pioneer sales for 2008 were $552.7 million compared to $183.6 million for the last four months of 2007, an increase of $369.1 million. Chlor Alkali Products’ sales, excluding Pioneer, increased $61.2 million, or 9%. The sales increase was due to increased ECU pricing, partially offset by lower volumes. The combined Olin and Pioneer chlorine and caustic soda ECU netback, excluding SunBelt, increased 19% to approximately $635 for 2008 compared to approximately $535 in 2007, which included Pioneer for the last four months. Freight costs included in the ECU netback increased 28% in 2008 compared to 2007. The combined Olin and Pioneer operating rate for 2008 was 82%, compared to the operating rate of 92% in 2007. The lower operating rate for 2008 was the result of lower chlorine demand and was also negatively affected by two hurricanes, which caused production and customer outages and disruptions to the transportation system.

Chlor Alkali posted segment income of $328.3 million for 2008 compared to $237.3 million for 2007. Chlor Alkali segment income included Pioneer income of $101.9 million and $29.2 million for 2008 and 2007, respectively. Chlor Alkali segment income, excluding Pioneer, was higher in 2008 by $18.3 million, or 9%, primarily because of increased selling prices ($108.4 million), partially offset by decreased volumes ($46.7 million), higher operating costs ($35.2 million), and lower SunBelt results ($7.5 million). Chlor Alkali segment income for 2008 also included a $2.6 million gain from a litigation recovery. Operating expenses increased primarily due to increases in distribution costs and manufacturing costs, which included higher electricity prices. The lower SunBelt earnings primarily resulted from lower volumes due to the impact of hurricane-related outages and other force majeure events at one of its chlorine customers partially offset by higher ECU selling prices in 2008. The operating results from SunBelt included interest expense of $4.4 million and $4.8 million in 2008 and 2007, respectively, on the SunBelt Notes.

Winchester

2009 Compared to 2008

Winchester sales were $567.7 million for 2009 compared to $489.1 million for 2008, an increase of $78.6 million, or 16%. Sales of ammunition to domestic and international commercial customers increased $66.1 million. Winchester continues to experience the above normal levels of demand that began around the November 2008 presidential election. The increase in demand has been across the majority of Winchester’s product offerings, including rifle, pistol and rimfire ammunition. Shipments to military customers also increased $20.3 million. These increases were partially offset by lower shipments to industrial customers, who primarily supply the construction sector, of $7.8 million and decreased shipments to law enforcement agencies of $3.3 million. On a volume basis, Winchester’s overall unit shipments increased 14%, which was driven by the higher level of commercial sales.

Winchester reported segment income of $68.6 million for 2009 compared to $32.6 million for 2008, an increase of $36.0 million, or 110%. The increase was primarily due to the impact of increased volumes and higher selling prices ($24.7 million) and decreased commodity and other material costs partially offset by higher operating costs ($10.7 million).

2008 Compared to 2007

Sales were $489.1 million in 2008 compared to $431.7 million for 2007, an increase of $57.4 million, or 13%. Sales of ammunition to domestic and international commercial customers increased $31.1 million. Shipments to law enforcement agencies increased $19.4 million for 2008 compared to 2007. Shipments to military customers increased $2.8 million.

Winchester reported segment income of $32.6 million for 2008 compared to $26.4 million for 2007, an increase of $6.2 million, or 23%. The increase was due to the impact of higher selling prices and increased volumes to law enforcement agencies ($56.1 million), which were partially offset by increased commodity and other material costs and higher operating costs ($46.0 million) and lower volumes primarily with commercial customers ($6.7 million). For 2008, the actual copper cost for Winchester increased by 11% compared to 2007, while the average price of lead increased 75% compared to 2007. The Winchester business consumes approximately four times as much lead as it does copper, and the year-over-year increase in the actual lead cost equates to approximately $25 million of annual expense.

Corporate/Other

2009 Compared to 2008

For 2009, pension income included in corporate/other was $22.3 million compared to $14.8 million for 2008. Pension income for 2008 included a curtailment charge of $4.1 million associated with the transition of a portion of our East Alton, IL Winchester hourly workforce and our McIntosh, AL Chlor Alkali hourly workforce from a defined benefit pension plan to a defined contribution pension plan. On a total company basis, defined benefit pension income for 2009 was $16.7 million compared to $7.6 million for 2008.

Credits to income for environmental investigatory and remedial activities were $58.0 million for 2009, which includes $82.1 million of recoveries from third parties of costs incurred and expensed in prior periods. Without these recoveries in 2009, charges to income for environmental investigatory and remedial activities would have been $24.1 million for 2009 compared with $27.7 million for 2008. These charges relate primarily to expected future investigatory and remedial activities associated with past manufacturing operations and former waste disposal sites.

For 2009, other corporate and unallocated costs were $63.1 million compared with $58.6 million in 2008, an increase of $4.5 million, or 8%. The increase was primarily due to higher asset retirement obligation charges of $4.4 million, primarily related to increases in estimated costs for certain assets, increased legal and legal-related settlement expenses of $3.3 million, which included costs for recovery actions for environmental costs previously incurred and expensed, increased consulting and professional fees of $1.5 million and higher salary and benefit costs of $1.3 million, partially offset by lower non-income taxes of $5.1 million, primarily due to a favorable resolution of a Canadian capital tax matter, and decreased management incentive compensation costs of $1.1 million, which includes mark-to-market adjustments on stock-based compensation.

2008 Compared to 2007

For 2008, pension income included in corporate/other was $14.8 million compared to pension expense of $3.9 million for 2007. The $18.7 million decrease in corporate pension expense was due to the combination of a 25-basis point increase in the liability discount rate in 2007, the $100 million voluntary contribution made to our defined benefit pension plan in May 2007, the favorable performance on plan assets in 2007, the benefits of the plan freeze for salary and certain non-bargained hourly employees, which became effective January 1, 2008, and the increase in the amortization period of actuarial losses. These decreases were partially offset by curtailment charges of $4.1 million associated with the transition of a portion of our East Alton, IL Winchester hourly workforce and our McIntosh, AL Chlor Alkali hourly workforce from a defined benefit pension plan to a defined contribution pension plan.

On a total company basis, defined benefit pension income for 2008 was $7.6 million compared to defined benefit pension expense of $33.5 million for 2007. The decrease in total company pension expense reflected curtailment charges of $7.4 million for 2007 relating to the Metals business and $7.9 million for the Metals allocated portion of service cost and the amortization of prior service cost components of pension expense, which were included in discontinued operations. This defined benefit pension cost reduction was partially offset by higher defined contribution pension costs. Total company defined contribution pension expense for 2008 was $11.3 million compared to $2.7 million for 2007.

Charges to income for environmental investigatory and remedial activities were $27.7 million for 2008, compared with $37.9 million in 2007. This provision related primarily to expected future investigatory and remedial activities associated with past manufacturing operations and former waste disposal sites. The decrease of $10.2 million was primarily due to a $7.9 million charge in 2007 related to costs at a former waste disposal site based on revised remediation estimates resulting from negotiations with a government agency.

For 2008, other corporate and unallocated costs were $58.6 million compared with $63.8 million in 2007, a decrease of $5.2 million, or 8%. The decrease was primarily due to lower asset retirement obligation charges of $3.6 million, primarily related to a reduction in the liability for a former chemical manufacturing location, lower legal and legal-related settlement expenses of $2.9 million, and lower consulting charges of $0.8 million, partially offset by increased management incentive compensation costs of $1.9 million, primarily resulting from mark-to-market adjustments on stock-based compensation.

2010 OUTLOOK

Net income in the first quarter of 2010 is projected to be in the $0.10 per diluted share range compared with $0.60 per diluted share in the first quarter of 2009.

In Chlor Alkali Products, the first quarter of 2010 segment earnings are expected to improve slightly compared to the fourth quarter of 2009 as we are anticipating some improvement in demand as compared to the fourth quarter of 2009. We also expect the first quarter 2010 chlorine and caustic soda shipments to improve from the first quarter of 2009. Chlor Alkali Products’ operating rates in the first quarter of 2010 are forecast to be in the low to mid 70% range, which is an improvement from both the fourth quarter of 2009 level of 70% and the first quarter of 2009 level of 65%. Fourth quarter 2009 ECU netbacks were approximately $425, which was an improvement from the approximately $375 experienced in the third quarter of 2009. First quarter 2010 ECU netbacks are anticipated to be comparable to the fourth quarter of 2009. The first quarter of 2009 ECU netback was a record, in our system, of approximately $765. We believe that ECU netbacks, in our system, bottomed out in the third quarter of 2009. In December 2009, a $75 per ton caustic soda price increase was announced. We expect to begin realizing this price increase in caustic soda in the second quarter of 2010.

Winchester first quarter 2010 segment earnings are expected to be similar to the first quarter of 2009 segment earnings of $17.0 million as higher than normal levels of demand are expected to continue in the first quarter of 2010. During the first quarter of 2010, Winchester announced price increases to be effective at the end of the first quarter of 2010. Similar increases were announced by Winchester’s major competitors. These increases are in reaction to the escalation in the prices of both copper and lead.

Winchester continues to experience the above normal levels of demand that began around the November 2008 presidential election. The increase in demand has been across the majority of Winchester’s product offerings, including rifle, pistol and rimfire ammunition. Additionally, we believe there is an industry-wide lack of ammunition inventory in the customer supply chain system. Winchester anticipates that higher than normal levels of demand will continue past the first quarter of 2010.

Without the 2009 recoveries of $82.1 million of environmental costs incurred and expensed in prior periods, we anticipate that 2010 charges for environmental investigatory and remedial activities will be 10% to 20% greater than the 2009 level of $24.1 million. As we look beyond 2009, we do not believe that there will be meaningful additional recoveries of environmental costs incurred and expensed in prior periods.

In 2010, we expect defined benefit pension income will be similar to the 2009 level. Based on the December 31, 2009 funding status, we will not be required to make any cash contributions to our domestic defined benefit pension plan in 2010, and we also believe it is unlikely we will be required to make any contributions in 2011. We do have a small Canadian defined benefit pension plan to which we made $4.5 million of contributions in 2009 and we anticipate approximately $4 million of contributions in 2010.

We believe the 2010 effective tax rate will be in the 37% to 38% range, before discrete items. During periods of low earnings, our effective tax rate can be significantly impacted by permanent tax deduction items, return to provision adjustments, changes in tax contingencies and valuation allowances, and tax credits.

In 2010, we expect our capital spending to be in the $70 million to $80 million range, which includes bleach manufacturing and shipping by railroad expansion projects at three of our chlor alkali facilities. This anticipated 2010 capital spending compares with the 2009 capital spending of $137.9 million. We are also actively developing a low salt, high strength bleach facility that will double the concentration of the bleach we manufacture, which should significantly reduce transportation costs. During 2010, we expect to initiate a $15 million to $20 million capital project to construct a low salt, high strength bleach facility to be co-located at one of our existing chlor alkali facilities. Additional investments in low salt, high strength bleach could follow in future years. As a result of the capitalization of the St. Gabriel, LA conversion and expansion project in late 2009, we expect 2010 depreciation expense to be approximately $90 million.

Total environmental-related cash outlays in 2009 decreased compared to 2008 and 2007 due to the recoveries from third parties of costs incurred and expensed in prior periods. Remedial and investigatory spending was lower in 2009 than 2008 due to reduced spending at two former Pioneer sites and principally completing an expansive investigation at a former manufacturing site in 2009 partially offset by spending in 2009 to complete remedial action at a site. Remedial and investigatory spending was lower in 2008 than 2007 due to an expansive investigation at a former manufacturing site and the implementation of remedial actions at five other sites in 2007. Total environmental-related cash outlays for 2010 are estimated to be approximately $63 million, of which $35 million is expected to be spent on investigatory and remedial efforts, $3 million on capital projects and $25 million on normal plant operations. Historically, we have funded our environmental capital expenditures through cash flow from operations and expect to do so in the future.

Cash outlays for remedial and investigatory activities associated with former waste sites and past operations were not charged to income but instead were charged to reserves established for such costs identified and expensed to income in prior years. Cash outlays for normal plant operations for the disposal of waste and the operation and maintenance of pollution control equipment and facilities to ensure compliance with mandated and voluntarily imposed environmental quality standards were charged to income.

In the United States, the establishment and implementation of federal, state, and local standards to regulate air, water and land quality affect substantially all of our manufacturing locations. Federal legislation providing for regulation of the manufacture, transportation, use, and disposal of hazardous and toxic substances, and remediation of contaminated sites, has imposed additional regulatory requirements on industry, particularly the chemicals industry. In addition, implementation of environmental laws, such as the Resource Conservation and Recovery Act and the Clean Air Act, has required and will continue to require new capital expenditures and will increase plant operating costs. Our Canadian facility is governed by federal environmental laws administered by Environment Canada and by provincial environmental laws enforced by administrative agencies. Many of these laws are comparable to the U.S. laws described above. We employ waste minimization and pollution prevention programs at our manufacturing sites.

We are party to various governmental and private environmental actions associated with past manufacturing facilities and former waste disposal sites. Associated costs of investigatory and remedial activities are provided for in accordance with generally accepted accounting principles governing probability and the ability to reasonably estimate future costs. Our ability to estimate future costs depends on whether our investigatory and remedial activities are in preliminary or advanced stages. With respect to unasserted claims, we accrue liabilities for costs that, in our experience, we may incur to protect our interests against those unasserted claims. Our accrued liabilities for unasserted claims amounted to $3.4 million at December 31, 2009. With respect to asserted claims, we accrue liabilities based on remedial investigation, feasibility study, remedial action and operation, maintenance and monitoring (OM&M) expenses that, in our experience, we may incur in connection with the asserted claims. Required site OM&M expenses are estimated and accrued in their entirety for required periods not exceeding 30 years, which reasonably approximates the typical duration of long-term site OM&M. Charges or credits to income for investigatory and remedial efforts were material to operating results in 2009, 2008 and 2007 and may be material to operating results in future years.

Environmental provisions (credited) charged to income, which are included in cost of goods sold, were as follows:

Recoveries from third parties of costs incurred and expensed in prior periods		(82.1	)		―		―
Total environmental (income) expense	$	(58.0	)	$	27.7	$	37.9

These charges relate primarily to remedial and investigatory activities associated with past manufacturing operations and former waste disposal sites.

Our total estimated environmental liability at the end of 2009, was attributable to 68 sites, 16 of which were USEPA National Priority List (NPL) sites. Ten sites accounted for 79% of our environmental liability and, of the remaining 58 sites, no one site accounted for more than 2% of our environmental liability. At one of these ten sites a remedial action plan is being implemented. At five of the ten sites, part of the site is subject to a remedial investigation and another part is in the long-term OM&M stage. At one of these ten sites, part of the site is subject to a remedial investigation, part to a remedial action plan, and another part is in the long-term OM&M stage. At two sites, part of the site is subject to a remedial action plan and part of the site to long-term OM&M. The one remaining site is in long-term OM&M. All ten sites are either associated with past manufacturing operations or former waste disposal sites. None of the ten largest sites represents more than 20% of the liabilities reserved on our consolidated balance sheet at December 31, 2009 for future environmental expenditures.

Our consolidated balance sheets included liabilities for future environmental expenditures to investigate and remediate known sites amounting to $166.1 million at December 31, 2009, and $158.9 million at December 31, 2008, of which $131.1 million and $123.9 million, respectively, were classified as other noncurrent liabilities. Our environmental liability amounts did not take into account any discounting of future expenditures or any consideration of insurance recoveries or advances in technology. These liabilities are reassessed periodically to determine if environmental circumstances have changed and/or remediation efforts and our estimate of related costs have changed. As a result of these reassessments, future charges to income may be made for additional liabilities. Of the $166.1 million included on our consolidated balance sheet at December 31, 2009 for future environmental expenditures, we currently expect to utilize $98.7 million of the reserve for future environmental expenditures over the next 5 years, $20.2 million for expenditures 6 to 10 years in the future, and $47.2 million for expenditures beyond 10 years in the future. These estimates are subject to a number of risks and uncertainties, as described in Item 1A “Risk Factors—Environmental Costs.”

Annual environmental-related cash outlays for site investigation and remediation, capital projects, and normal plant operations are expected to range between $50 million to $70 million over the next several years, $20 million to $40 million of which is for investigatory and remedial efforts, which are expected to be charged against reserves recorded on our balance sheet. While we do not anticipate a material increase in the projected annual level of our environmental-related cash outlays, there is always the possibility that such an increase may occur in the future in view of the uncertainties associated with environmental exposures. Environmental exposures are difficult to assess for numerous reasons, including the identification of new sites, developments at sites resulting from investigatory studies, advances in technology, changes in environmental laws and regulations and their application, changes in regulatory authorities, the scarcity of reliable data pertaining to identified sites, the difficulty in assessing the involvement and financial capability of other PRPs, and our ability to obtain contributions from other parties and the lengthy time periods over which site remediation occurs. It is possible that some of these matters (the outcomes of which are subject to various uncertainties) may be resolved unfavorably to us, which could materially adversely affect our financial position or results of operations. At December 31, 2009, we estimate we may have additional contingent environmental liabilities of $50 million in addition to the amounts for which we have already recorded as a reserve.

LEGAL MATTERS AND CONTINGENCIES

We, and our subsidiaries, are defendants in various legal actions (including proceedings based on alleged exposures to asbestos) incidental to our past and current business activities. We describe some of these matters in “Item 3—Legal Proceedings.” While we believe that none of these legal actions will materially adversely affect our financial position, in light of the inherent uncertainties of litigation, we cannot at this time determine whether the financial impact, if any, of these matters will be material to our results of operations.

During the ordinary course of our business, contingencies arise resulting from an existing condition, situation, or set of circumstances involving an uncertainty as to the realization of a possible gain contingency. In certain instances such as environmental projects, we are responsible for managing the cleanup and remediation of an environmental site. There exists the possibility of recovering a portion of these costs from other parties. We account for gain contingencies in accordance with the provisions of ASC 450 “Contingencies” (ASC 450), formerly SFAS No. 5, “Accounting for Contingencies,” (SFAS No. 5), and therefore do not record gain contingencies and recognize income until it is earned and realizable.

Operating Activities

For 2009, cash provided by operating activities increased by $84.6 million from 2008 primarily due to a smaller increase in working capital than the prior year. In 2009, working capital increased $22.6 million compared with an increase of $97.8 million in 2008. Receivables decreased from December 31, 2008 by $29.7 million, primarily due to lower sales. Our days sales outstanding was consistent with prior year. Accounts payable and accrued liabilities decreased from December 31, 2008 by $43.5 million, primarily as a result of the timing of payments and a $20.6 million payment for the final settlement of working capital on the sale of the Metals business, which was consistent with the estimated working capital adjustment we anticipated from the transaction. The 2009 cash from operations was also affected by a $57.9 million decrease in cash tax payments. In 2009, we made contributions to our foreign defined benefit pension plan of $4.5 million.

For 2008, cash provided by operating activities from continuing operations increased by $16.8 million from 2007 primarily due to the $100 million voluntary contribution to our domestic defined benefit pension plan made in 2007 and higher earnings in 2008, mostly offset by increased working capital. In 2008, working capital increased $97.8 million compared with a decrease of $47.3 million in 2007. Receivables increased from December 31, 2007 by $9.5 million, as a result of increased selling prices in both our Chlor Alkali and Winchester businesses and improved volumes at Winchester partially offset by lower December 2008 chlorine and caustic soda volumes compared with 2007. Our days sales outstanding decreased by approximately two days from 2007. Inventories increased from December 31, 2007 by $25.0 million primarily due to increased ammunition inventories and higher raw material costs in Winchester. Accounts payable and accrued liabilities decreased from December 31, 2007 by $66.1 million, primarily as a result of payments of retained Metals liabilities. The 2008 cash from operations was also affected by a $24.6 million increase in cash tax payments.

Capital Expenditures

Capital spending was $137.9 million, $180.3 million, and $76.1 million in 2009, 2008 and 2007, respectively. Capital spending in 2009 included $69.6 million for the St. Gabriel, LA facility conversion and expansion project and also increased investments in our bleach operations. The increase in 2008 was primarily due to spending of $87.2 million for the St. Gabriel, LA facility conversion and expansion project and increased spending for a major maintenance capital project at our McIntosh, AL facility. Capital spending in 2007 included $9.1 million for the St. Gabriel, LA facility conversion and expansion project and also spending required to increase bleach capacity in our Chlor Alkali Products operations. Capital spending was 196%, 265%, and 161% of depreciation in 2009, 2008 and 2007, respectively.

In 2010, we expect our capital spending to be in the $70 million to $80 million range, which includes bleach manufacturing and shipping by railroad expansion projects at three of our Chlor Alkali facilities. We are also actively developing a low salt, high strength bleach facility that will double the concentration of the bleach we manufacture, which should significantly reduce transportation costs. During 2010, we expect to initiate a $15 million to $20 million capital project to construct a low salt, high strength bleach facility to be co-located at one of our existing chlor alkali facilities.

During the first quarter of 2007, we entered into a sale/leaseback transaction for chlorine railcars that were acquired in 2005 and 2006. This transaction reduced our fixed assets by approximately $16.0 million.

Investing Activities

On August 31, 2007, we acquired Pioneer and paid cash of $426.1 million. We also acquired cash of $126.4 million with the Pioneer acquisition.

On November 19, 2007, we completed the sale of the Metals business to Global. We received net proceeds from the sale of $380.8 million.

During 2007, we sold $50.0 million of short-term investments in corporate debt securities, which were purchased during 2006.

On January 31, 2007, we entered into a sale/leaseback agreement for chlorine railcars in our Chlor Alkali Products segment that were acquired in 2005 and 2006. We received proceeds from the sale of $14.8 million.

The 2009, 2008 and 2007 distributions from affiliated companies, net, represented primarily our share of the SunBelt joint venture’s operating results, net of cash payments to the affiliates. Also, included in 2007 was our purchase for cash of $11.6 million for an equity interest in a limited liability company that owns a bleach and related chemical manufacturing facility (bleach joint venture).

Financing Activities

In August 2009, we sold $150.0 million of 2019 Notes with a maturity date of August 15, 2019. The 2019 Notes were issued at 99.19% of par value, providing a yield to maturity to investors of 9.0%. Interest will be paid semi-annually beginning on February 15, 2010. Proceeds of $145.5 million, after expenses of $3.3 million, from the 2019 Notes will be used to further strengthen our long-term liquidity given uncertain economic times.

In February 2009, we reissued $1.5 million of variable rate Mississippi industrial revenue bonds, which were redeemed by us at par value in October 2008. These were originally issued in 2005 in conjunction with our relocation of a portion of our Winchester operations to Oxford, MS.

In March 2008, we repaid industrial development and environmental improvement tax exempt bonds, which matured totaling $7.7 million that were issued through the parish of Calcasieu, LA and the town of McIntosh, AL. In January 2008, we repaid the remaining $2.1 million of the 2.75% Convertible Senior Subordinated Notes due 2027 (Convertible Notes) acquired from Pioneer.

During 2007, $117.9 million of the Convertible Notes issued by Pioneer and the related $25.8 million premium were repaid using drawings from our Accounts Receivable Facility and cash.

During 2009, 2008 and 2007, we issued 1,260,693; 947,643; and 836,131 shares of common stock, respectively, with a total value of $16.9 million, $18.1 million and $15.5 million, respectively, to the Olin CEOP. These shares were issued to satisfy the investment in our common stock resulting from employee contributions, our matching contributions, retirement contributions and re-invested dividends.

The percent of total debt to total capitalization increased to 32.6% at December 31, 2009, from 26.4% at year-end 2008 and 28.1% at year-end 2007. The 2009 increase from 2008 was due primarily to the higher level of long-term debt at December 31, 2009 resulting from the issuance of the 2019 Notes in August 2009, partially offset by higher shareholders’ equity resulting from the net income for the year ended December 31, 2009. The 2008 decrease from 2007 was due primarily to a lower level of outstanding debt resulting from repayments and the higher shareholders’ equity resulting from net income offset by the non-cash charge for our pension and other postretirement plans.

Dividends per common share were $0.80 in 2009, 2008 and 2007. Total dividends paid on common stock amounted to $62.5 million, $60.6 million and $59.2 million in 2009, 2008 and 2007, respectively.

The payment of cash dividends is subject to the discretion of our board of directors and will be determined in light of then-current conditions, including our earnings, our operations, our financial condition, our capital requirements and other factors deemed relevant by our board of directors. In the future, our board of directors may change our dividend policy, including the frequency or amount of any dividend, in light of then-existing conditions.

LIQUIDITY AND OTHER FINANCING ARRANGEMENTS

Our principal sources of liquidity are from cash and cash equivalents, cash flow from operations and short-term borrowings under our senior revolving credit facility and borrowings under our Accounts Receivable Facility. Additionally, we believe that we have access to the debt and equity markets.

Cash flow from operations is variable as a result of both the seasonal and the cyclical nature of our operating results, which have been affected by seasonal and economic cycles in many of the industries we serve, such as the vinyls, urethanes, bleach, ammunition and pulp and paper. The seasonality of the ammunition business, which is typically driven by the fall hunting season, and the seasonality of the vinyls and bleach businesses, which are stronger in periods of warmer weather, typically cause working capital to fluctuate between $50 million to $100 million over the course of the year. Cash flow from operations is affected by changes in ECU selling prices caused by the changes in the supply/demand balance of chlorine and caustic, resulting in the chlor alkali business having significant leverage on our earnings. For example, assuming all other costs remain constant and internal consumption remains approximately the same, a $10 per ECU selling price change equates to an approximate $17 million annual change in our revenues and pretax profit when we are operating at full capacity.

The cash increase of $212.0 million for 2009, reflects the cash proceeds from the $150.0 million of 2019 Notes issued in August 2009, and the receipt of the majority of the proceeds from the recoveries of environmental costs incurred and expensed in prior periods, offset by both the normal seasonal growth in working capital, one-time items mentioned above, and capital spending associated with the conversion and expansion project at our St. Gabriel, LA facility. Based on these factors, we believe the December 31, 2009 cash balance of $458.5 million, and the availability of approximately $294.6 million of liquidity from our senior revolving credit facility and our Accounts Receivable Facility is sufficient liquidity to meet our short-term and long-term needs. Additionally, we believe that we have access to the debt and equity markets.

Since 2006, we held corporate debt securities with a par value of $26.6 million. On October 1, 2008, the issuer of these debt securities announced it would cease trading and appoint a receiver as a result of financial market turmoil. The decline in the market value of the assets supporting these debt securities negatively impacted the liquidity of the issuer. We determined that these debt securities had no fair market value due to the actions taken by the issuer, turmoil in the financial markets, the lack of liquidity of the issuer, and the lack of trading in these debt securities. Because of the unlikelihood that these debt securities would recover in value, we recorded an after-tax impairment loss of $26.6 million in other income (expense) in the third quarter of 2008. We are currently unable to utilize the capital loss resulting from the impairment of these corporate debt securities; therefore, no tax benefit has been recognized for the impairment loss.

On October 29, 2007, we entered into a new $220 million five-year senior revolving credit facility, which replaced the $160 million senior revolving credit facility. During the first quarter of 2008, we increased our senior revolving credit facility by $20 million to $240 million by adding an additional lending institution. The new senior revolving credit facility will expire in October 2012. We have the option to expand the $240 million senior revolving credit facility by an additional $60 million through adding a maximum of two additional lending institutions each year. At December 31, 2009, we had $219.6 million available under this senior revolving credit facility, because we had issued $20.4 million of letters of credit under a $110 million subfacility. Under the senior revolving credit facility, we may select various floating rate borrowing options. The actual interest rate paid on borrowings under the senior revolving credit facility is based on a pricing grid which is dependent upon the leverage ratio as calculated under the terms of the facility at the end of the prior fiscal quarter. The facility includes various customary restrictive covenants, including restrictions related to the ratio of debt to earnings before interest expense, taxes, depreciation and amortization (leverage ratio) and the ratio of earnings before interest expense, taxes, depreciation and amortization to interest expense (coverage ratio). Compliance with these covenants is determined quarterly based on the operating cash flows for the last four quarters. We were in compliance with all covenants and restrictions under all our outstanding credit agreements as of December 31, 2009 and 2008, and no event of default had occurred that would permit the lenders under our outstanding credit agreements to accelerate the debt if not cured. In the future, our ability to generate sufficient operating cash flows, among other factors, will determine the amounts available to be borrowed under these facilities. As of December 31, 2009, there were no covenants or other restrictions that limited our ability to borrow.

At December 31, 2009, we had letters of credit of $46.7 million outstanding, of which $20.4 million were issued under our $240 million senior revolving credit facility. In addition to our senior revolving credit facility, we have a $35 million letter of credit facility. These letters of credit were used to support certain long-term debt, capital expenditure commitments, certain workers compensation insurance policies, and plant closure and post-closure obligations.

We have a $75 million, 364-day Accounts Receivable Facility, renewable annually for five years, which expires in July 2012. The Accounts Receivable Facility provides for the sale of our eligible trade receivables to a third party conduit through a wholly-owned, bankruptcy-remote, special purpose entity that is consolidated for financial statement purposes. As of December 31, 2009, we had nothing drawn under the Accounts Receivable Facility. At December 31, 2009, we had $75 million available under the Accounts Receivable Facility based on eligible trade receivables. The Accounts Receivable Facility contains specific covenants relating to the ability of the lender to obtain or maintain a first priority lien on the receivables. In addition, the Accounts Receivable Facility incorporates the leverage and coverage covenants that are contained in the senior revolving credit facility.

Our current debt structure is used to fund our business operations. As of December 31, 2009, we had long-term borrowings of $398.4 million of which $4.7 million was at variable rates. Annual maturities of long-term debt are none in 2010, $80.5 million in 2011, none in 2012, $11.4 million in 2013, $1.8 million in 2014 and a total of $304.7 million thereafter. Commitments from banks under our senior revolving credit facility and Accounts Receivable Facility are additional sources of liquidity.

We have entered into interest rate swaps on $26.6 million of our underlying fixed-rate debt obligations whereby we agree to pay variable rates to a counterparty who, in turn, pays us fixed rates. The counterparty to these agreements is Citibank, N.A., a major financial institution. We have designated the swap agreements as fair value hedges of the risk of changes in the value of fixed rate debt due to changes in interest rates for a portion of our fixed rate borrowings. Accordingly, the swap agreements have been recorded at their fair market value of $1.4 million and are included in other assets on the accompanying consolidated balance sheet, with a corresponding increase in the carrying amount of the related debt. No gain or loss has been recorded as the swaps met the criteria to qualify for hedge accounting treatment with no ineffectiveness.

In 2001 and 2002, we entered into interest rate swaps on $75 million of our underlying fixed-rate debt obligations, whereby we agreed to pay variable rates to a counterparty who, in turn, pays us fixed rates. The counterparty to these agreements is Citibank, N.A., a major financial institution. In January 2009, we entered into a $75 million fixed interest rate swap with equal and opposite terms as the $75 million variable interest rate swaps on the 9.125% senior notes due in 2011 (2011 Notes). We have agreed to pay a fixed rate to a counterparty who, in turn, pays us variable rates. The counterparty to this agreement is Bank of America, a major financial institution. The result was a gain of $7.9 million on the $75 million variable interest rate swaps, which will be recognized through 2011. As of December 31, 2009, $5.5 million of this gain was included in long-term borrowings. In January 2009, we de-designated our $75 million interest rate swaps that had previously been designated as fair value hedges. The $75 million variable interest rate swaps and the $75 million fixed interest rate swap do not meet the criteria for hedge accounting. All changes in the fair value of these interest rate swaps are recorded currently in earnings.

We have registered an undetermined amount of securities with the SEC, so that, from time-to-time, we may issue debt securities, preferred stock and/or common stock and associated warrants in the public market under that registration statement.

OFF-BALANCE SHEET ARRANGEMENTS

We use operating leases for certain properties, such as railroad cars; distribution, warehousing and office space; and data processing and office equipment. Virtually none of our lease agreements contain escalation clauses or step rent provisions. Assets under capital leases are not significant. During the first quarter of 2007, we entered into a $16.0 million sale/leaseback transaction for chlorine railcars that were acquired in 2005 and 2006.

In conjunction with the St. Gabriel conversion and expansion project, we entered into a twenty-year brine and pipeline supply agreement with PetroLogistics Olefins, LLC (PetroLogistics). PetroLogistics installed, owns and operates, at its own expense, a pipeline supplying brine to the St. Gabriel, LA facility. Beginning November 2009, we are obligated to make a fixed annual payment over the life of the contract of $2.0 million for use of the pipeline, regardless of the amount of brine purchased. We also have a minimum usage requirement for brine of $8.4 million over the first five-year period of the contract. After the first five-year period, the contract contains a buy out provision exercisable by us for $12.0 million.

On December 31, 1997, we entered into a long-term, sulfur dioxide supply agreement with Alliance Specialty Chemicals, Inc. (Alliance), formerly known as RFC SO2, Inc. Alliance has the obligation to deliver annually 36,000 tons of sulfur dioxide. Alliance owns the sulfur dioxide plant, which is located at our Charleston, TN facility and is operated by us. The price for the sulfur dioxide is fixed over the life of the contract and, under the terms of the contract, we are obligated to make a monthly payment of $0.2 million regardless of the amount of sulfur dioxide purchased. Commitments related to this agreement are $2.4 million per year for 2010 and 2011 and $0.6 million in 2012. This supply agreement expires in 2012.

We and our partner, PolyOne, own equally SunBelt. Oxy Vinyls is required to purchase 250 thousand tons of chlorine based on a formula related to its market price. Prior to July 2007, PolyOne had an ownership interest in Oxy Vinyls. We market the excess chlorine and all of the caustic soda produced. The construction of this plant and equipment was financed by the issuance of $195.0 million of Guaranteed Senior Secured Notes due 2017. SunBelt sold $97.5 million of Guaranteed Senior Secured Notes due 2017, Series O, and $97.5 million of Guaranteed Senior Secured Notes due 2017, Series G. We refer to these notes as the SunBelt Notes. The SunBelt Notes bear interest at a rate of 7.23% per annum payable semiannually in arrears on each June 22 and December 22.

We have guaranteed the Series O Notes, and PolyOne has guaranteed the Series G Notes, in both cases pursuant to customary guaranty agreements. Our guarantee and PolyOne’s guarantee are several, rather than joint. Therefore, we are not required to make any payments to satisfy the Series G Notes guaranteed by PolyOne. An insolvency or bankruptcy of PolyOne will not automatically trigger acceleration of the SunBelt Notes or cause us to be required to make payments under our guarantee, even if PolyOne is required to make payments under its guarantee. However, if SunBelt does not make timely payments on the SunBelt Notes, whether as a result of a failure to pay on a guarantee or otherwise, the holders of the SunBelt Notes may proceed against the assets of SunBelt for repayment. If we were to make debt service payments under our guarantee, we would have a right to recover such payments from SunBelt.

Beginning on December 22, 2002 and each year through 2017, SunBelt is required to repay $12.2 million of the SunBelt Notes, of which $6.1 million is attributable to the Series O Notes. After the payment of $6.1 million on the Series O Notes in December 2009, our guarantee of these notes was $48.8 million. In the event SunBelt cannot make any of these payments, we would be required to fund the payment on the Series O Notes. In certain other circumstances, we may also be required to repay the SunBelt Notes prior to their maturity. We and PolyOne have agreed that, if we or PolyOne intend to transfer our respective interests in SunBelt and the transferring party is unable to obtain consent from holders of 80% of the aggregate principal amount of the indebtedness related to the guarantee being transferred after good faith negotiations, then we and PolyOne will be required to repay our respective portions of the SunBelt Notes. In such event, any make whole or similar penalties or costs will be paid by the transferring party.

Excluding our guarantee of the SunBelt Notes described above, our long-term contractual commitments, including the on and off-balance sheet arrangements, consisted of the following:

	Payments Due by Period
Contractual Obligations	Total		Less than 1 Year		1-3 Years		3-5 Years		More than 5 Years

Total	$	1,073.6	$	140.0	$	244.8	$	131.6	$	557.2

(a)

For the purposes of this table, we have assumed for all periods presented that there are no changes in the principal amount of any variable rate debt from the amounts outstanding on December 31, 2009 and that there are no changes in the rates from those in effect at December 31, 2009 which ranged from 0.3% to 9.125%.

(b)

These amounts are only estimated payments assuming an annual expected rate of return on pension plan assets of 8.5%, and a discount rate on pension plan obligations of 5.75%. These estimated payments are subject to significant variation and the actual payments may be more than the amounts estimated. Given the inherent uncertainty as to actual minimum funding requirements for qualified defined benefit pension plans, no amounts are included in this table for any period beyond one year. As a result of the asset allocation adjustment, the favorable asset performance in 2006, 2007 and 2009, the $100.0 million and $80.0 million voluntary contributions made in 2007 and 2006, respectively, and the benefits from the plan freeze, offset by the unfavorable performance on plan assets in 2008, based on the current funding requirements, we will not be required to make any cash contributions to the domestic defined benefit pension plan at least through 2010. We do have a small Canadian defined benefit pension plan to which we made $4.5 million of contributions in 2009 and we anticipate approximately $4.0 million of contributions in 2010. See discussion on “Pension Protection Act of 2006” amended by “The Worker, Retiree, and Employer Recovery Act” in “Pension Plans” in the notes to the consolidated financial statements.

Non-cancelable operating leases and purchasing commitments are utilized in our normal course of business for our projected needs. For losses that we believe are probable and which are estimable we have accrued for such amounts in our consolidated balance sheets. In addition to the table above, we have various commitments and contingencies including: defined benefit and postretirement healthcare plans (as described below), environmental matters (see “Environmental Matters” included in Item 7—“Management’s Discussion and Analysis of Financial Condition and Results of Operations”), and litigation claims (see Item 3—“Legal Proceedings”).

We have several defined benefit and defined contribution pension plans, as described in the “Pension Plans” note in the notes to consolidated financial statements. We fund the defined benefit pension plans based on the minimum amounts required by law plus such amounts we deem appropriate. We have postretirement healthcare plans that provide health and life insurance benefits to certain retired employees and their beneficiaries, as described in the "Postretirement Benefits" note in the notes to consolidated financial statements. These other postretirement plans are not pre-funded and expenses are paid by us as incurred.

We also have standby letters of credit of $46.7 million of which $20.4 million have been issued through our senior revolving credit facility. At December 31, 2009, we had $219.6 million available under our senior revolving credit facility.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Our discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, sales and expenses, and related disclosure of contingent assets and liabilities. Significant estimates in our consolidated financial statements include goodwill recoverability, environmental, restructuring and other unusual items, litigation, income tax reserves including deferred tax asset valuation allowances, pension, postretirement and other benefits and allowance for doubtful accounts. We base our estimates on prior experience, facts and circumstances and other assumptions. Actual results may differ from these estimates.

We believe the following critical accounting policies affect the more significant judgments and estimates used in the preparation of the consolidated financial statements.

Goodwill

Goodwill is not amortized, but is reviewed annually in the fourth quarter and/or when circumstances or other events indicate that impairment may have occurred. Circumstances that could trigger an impairment test include but are not limited to: a significant adverse change in the business climate; a significant adverse legal judgment; adverse cash flow trends; an adverse action or assessment by a government agency; unanticipated competition; decline in our stock price; and a significant restructuring charge within a reporting unit. The annual impairment test involves the comparison of the estimated fair value of a reporting unit to its carrying amount. We define reporting units at the business segment level or one level below the business segment, which for our Chlor Alkali Products segment are the U.S. operations and Canadian operations. For purposes of testing goodwill for impairment, goodwill has been allocated to these reporting units to the extent it relates to each reporting unit.

We use a discounted cash flow approach to develop the estimated fair value of a reporting unit. Management judgment is required in developing the assumptions for the discounted cash flow model. We also corroborate our discounted cash flow analysis by evaluating a market-based approach that considers earnings before interest, taxes, depreciation and amortization (EBITDA) multiples from a representative sample of comparable public companies in the chemical industry. An impairment would be recorded if the carrying amount exceeded the estimated fair value. No impairment charges were recorded for 2009, 2008 or 2007.

The discount rate, profitability assumptions, terminal growth rate and cyclical nature of our chlor alkali business are the material assumptions utilized in the discounted cash flow model used to estimate the fair value of each reporting unit. The discount rate reflects a weighted-average cost of capital, which is calculated based on observable market data. Some of these data (such as the risk free or treasury rate and the pretax cost of debt) are based on the market data at a point in time. Other data (such as the equity risk premium) are based upon market data over time for a peer group of companies in the chemical manufacturing industry with a market capitalization premium added, as applicable.

The discounted cash flow analysis requires estimates, assumptions and judgments about future events. Our analysis uses our internally generated long-range plan. Our discounted cash flow analysis uses the assumptions in our long-range plan about terminal growth rates, forecasted capital expenditures, and changes in future working capital requirements to determine the implied fair value of each reporting unit. The long-range plan reflects management judgment, supplemented by independent chemical industry analyses which provide multi-year chlor alkali industry operating and pricing forecasts.

We believe the assumptions used in our discounted cash flow analysis are appropriate and result in reasonable estimates of the implied fair value of each reporting unit. However, given the economic environment and the uncertainties regarding the impact on our business, there can be no assurance that our estimates and assumptions, made for purposes of our goodwill impairment testing during the fourth quarter of 2009, will prove to be an accurate prediction of the future. In order to evaluate the sensitivity of the fair value calculations on the goodwill impairment test, we applied a hypothetical 10% decrease to the fair value of each reporting unit. In all cases, the estimated fair value of the reporting units exceeded the carrying value of the reporting units by a substantial amount. We also applied a hypothetical decrease of 100-basis points in our terminal growth rate or an increase of 100-basis points in our weighted-average cost of capital to test the fair value calculation. The estimated fair value of the reporting units derived in these calculations also exceeded our book value by a substantial amount for each of our reporting units. If our assumptions regarding forecasted sales or gross margins are not achieved, we may be required to record goodwill impairment charges in future periods. It is not possible at this time to determine if any such future impairment charge would result or, if it does, whether such charge would be material.

Environmental

Accruals (charges to income) 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 upon current law and existing technologies. These amounts, which are not discounted and are exclusive of claims against third parties, are adjusted periodically as assessments and remediation efforts progress or additional technical or legal information becomes available. Environmental costs are capitalized if the costs increase the value of the property and/or mitigate or prevent contamination from future operations. Environmental costs and recoveries are included in costs of goods sold.

Environmental exposures are difficult to assess for numerous reasons, including the identification of new sites, developments at sites resulting from investigatory studies, advances in technology, changes in environmental laws and regulations and their application, changes in regulatory authorities, the scarcity of reliable data pertaining to identified sites, the difficulty in assessing the involvement and financial capability of other PRPs and our ability to obtain contributions from other parties and the lengthy time periods over which site remediation occurs. It is possible that some of these matters (the outcomes of which are subject to various uncertainties) may be resolved unfavorably to us, which could materially adversely affect our financial position or results of operations.

Pension and Postretirement Plans

We account for our defined benefit pension plans and non-pension postretirement benefit plans using actuarial models required by ASC 715, formerly SFAS No. 87 and SFAS No. 106, respectively. These models use an attribution approach that generally spreads the financial impact of changes to the plan and actuarial assumptions over the average remaining service lives of the employees in the plan. Changes in liability due to changes in actuarial assumptions such as discount rate, rate of compensation increases and mortality, as well as annual deviations between what was assumed and what was experienced by the plan are treated as gains or losses. The principle underlying the required attribution approach is that employees render service over their average remaining service lives on a relatively smooth basis and, therefore, the accounting for benefits earned under the pension or non-pension postretirement benefits plans should follow the same relatively smooth pattern. With the closure of our defined benefit pension plan to new entrants, the freezing of our domestic defined benefit pension plan for salaried and certain non-bargained hourly employees that became effective January 1, 2008 and the sale of the Metals business, substantially all defined benefit pension plan participants beginning in 2008 were inactive; therefore, actuarial gains and losses are now being amortized based upon the remaining life expectancy of the inactive plan participants rather than the future service period of the active participants, which was the amortization period used prior to 2008. For the year ended December 31, 2007, the average remaining life expectancy of the inactive participants in the defined benefit pension plan was 19 years; compared to the average remaining service lives of the active employees in the defined benefit pension plan of 10.7 years. The increase in the amortization period of actuarial losses had the effect of increasing 2008 defined benefit pension income compared to 2007. For the years ended December 31, 2009 and 2008, the average remaining life expectancy of the inactive participants in the defined benefit pension plan was 19 years.

One of the key assumptions for the net periodic pension calculation is the expected long-term rate of return on plan assets, used to determine the “market-related value of assets.” (The “market-related value of assets” recognizes differences between the plan’s actual return and expected return over a five year period). The required use of an expected long-term rate of return on the market-related value of plan assets may result in recognized pension income that is greater or less than the actual returns of those plan assets in any given year. Over time, however, the expected long-term returns are designed to approximate the actual long-term returns and, therefore, result in a pattern of income and expense recognition that more closely matches the pattern of the services provided by the employees. As differences between actual and expected returns are recognized over five years, they subsequently generate gains and losses that are subject to amortization over the average remaining life expectancy of the inactive plan participants, as described in the preceding paragraph.

We use long-term historical actual return information, the mix of investments that comprise plan assets, and future estimates of long-term investment returns by reference to external sources to develop the expected return on plan assets as of December 31.

The discount rate assumptions used for pension and non-pension postretirement benefit plan accounting reflect the rates available on high-quality fixed-income debt instruments on December 31 of each year. The rate of compensation increase is based upon our long-term plans for such increases. For retiree medical plan accounting, we review external data and our own historical trends for healthcare costs to determine the healthcare cost trend rates.

Changes in pension costs may occur in the future due to changes in these assumptions resulting from economic events. For example, holding all other assumptions constant, a 100-basis point decrease or increase in the assumed rate of return on plan assets would have decreased or increased, respectively, the 2009 defined benefit pension plan income by approximately $15.6 million. Holding all other assumptions constant, a 50-basis point decrease in the discount rate used to calculate pension income for 2009 and the projected benefit obligation as of December 31, 2009 would have decreased pension income by $1.4 million and increased the projected benefit obligation by $82.0 million. A 50-basis point increase in the discount rate used to calculate pension income for 2009 and the projected benefit obligation as of December 31, 2009 would have increased pension income by $2.7 million and decreased the projected benefit obligation by $83.0 million. For additional information on long-term rates of return, discount rates and projected healthcare costs projections, see “Pension Plans” and “Postretirement Benefits” in the notes to the consolidated financial statements.

NEW ACCOUNTING PRONOUNCEMENTS

In January 2010, the FASB issued Accounting Standards Update (ASU) 2010-06 “Improving Disclosures About Fair Value Measurements” (ASU 2010-06), which amends ASC 820 “Fair Value Measurements and Disclosures” (ASC 820). This update adds new fair value disclosure requirements about transfers into and out of Level 1 and 2 and separate disclosures about purchases, sales, issuances, and settlements related to Level 3 measurements. This update expands disclosures on valuation techniques and inputs used to measure fair value. This update is effective for fiscal years beginning after December 15, 2009, except for the requirement to provide the Level 3 activity of purchases, sales, issuances, and settlements, which will be effective for fiscal years beginning after December 15, 2010. We will adopt the provisions of ASU 2010-06 in 2010, except for the requirement to provide the additional Level 3 activity, which will be adopted in 2011. This update will require additional disclosure in our first quarter 2010 condensed financial statements. The adoption of this update will not have a material effect on our consolidated financial statements.

In July 2009, the FASB issued SFAS No. 168, “The FASB Accounting Standards Codification™ and the Hierarchy of Generally Accepted Accounting Principles,” (the Codification), which was incorporated into ASC 105 “Generally Accepted Accounting Principles” (ASC 105). The Codification will be the single source of authoritative U.S. generally accepted accounting principles. The Codification does not change generally accepted accounting principles, but is intended to make it easier to find and research issues. The Codification introduces a new structure that takes accounting pronouncements and organizes them by approximately 90 accounting topics. The Codification was effective for interim and fiscal years ending after September 15, 2009. We adopted the Codification on July 1, 2009. The adoption of this statement did not have a material effect on our consolidated financial statements but changed our reference to generally accepted accounting principles beginning in the third quarter of 2009.

In June 2009, the FASB issued SFAS No. 166, “Accounting for Transfers of Financial Assets” (SFAS No. 166), which was incorporated into ASC 860 “Transfers and Servicing” (ASC 860) and SFAS No. 167, “Amendments to FASB Interpretation No. 46(R)” (SFAS No. 167), which was incorporated into ASC 810 “Consolidation” (ASC 810). These statements changed the way entities account for securitizations and special-purpose entities. The new standards eliminate existing exceptions, strengthen the standards relating to securitizations and special-purpose entities, and enhance disclosure requirements. Both of these statements are effective for fiscal years beginning after November 15, 2009. The adoption of these statements will not have a material effect on our consolidated financial statements.

In May 2009, the FASB issued SFAS No. 165, “Subsequent Events” (SFAS No. 165), which was incorporated into ASC 855 “Subsequent Events” (ASC 855). ASC 855 provides guidance on management’s assessment of subsequent events. The statement is not expected to significantly change practice because its guidance is similar to that in American Institute of Certified Public Accountants Professional Standards U.S. Auditing Standards Section 560, “Subsequent Events,” with some modifications. This statement became effective for us on June 15, 2009. The adoption of this statement did not have a material effect on our consolidated financial statements.

In April 2009, the FASB issued three Staff Positions (FSP) intended to provide additional application guidance and enhance disclosures regarding fair value measurements and impairments of securities. FSP SFAS No. 157-4, “Determining Fair Value When the Volume and Level of Activity for the Asset or Liability Have Significantly Decreased and Identifying Transactions That Are Not Orderly” (SFAS No. 157-4) provided guidelines for making fair value measurements more consistent with the principles presented in ASC 820. FSP SFAS No. 107-1 and APB 28-1, “Interim Disclosures about Fair Value of Financial Instruments” (SFAS No. 107-1 and APB 28-1), which were incorporated into ASC 825 “Financial Instruments” (ASC 825), enhanced consistency in financial reporting by increasing the frequency of fair value disclosures. FSP SFAS No. 115-2 and SFAS No. 124-2, “Recognition and Presentation of Other-Than-Temporary Impairments” (SFAS No. 115-2 and SFAS No. 124-2), which were incorporated into ASC 320 “Investments – Debt and Equity Securities” (ASC 320), provided additional guidance designed to create greater clarity and consistency in accounting for and presenting impairment losses on securities.

The position updating ASC 820 related to determining fair values when there is no active market or where the price inputs being used represent distressed sales. This position stated that the objective of fair value measurement is to reflect how much an asset would be sold for in an orderly transaction (as opposed to a distressed or forced transaction) at the date of the financial statements under current market conditions.

The position updating ASC 825 related to fair value disclosures for any financial instruments that are not currently reflected on the balance sheet at fair value. Prior to issuing this position, fair values for these assets and liabilities were only disclosed once a year. This position required these disclosures on a quarterly basis, providing qualitative and quantitative information about fair value estimates for all those financial instruments not measured on the balance sheet at fair value.

The position updating ASC 320 on other-than-temporary impairments is intended to bring greater consistency to the timing of impairment recognition, and provide greater clarity to investors about the credit and noncredit components of impaired debt securities that are not expected to be sold. The measure of impairment in comprehensive income remains fair value. This position also required increased and more timely disclosures sought by investors regarding expected cash flows, credit losses, and an aging of securities with unrealized losses.

These positions became effective for interim and fiscal years ending after June 15, 2009, with early adoption permitted. We adopted these positions as of March 31, 2009. The adoption of these positions did not have a material effect on our consolidated financial statements.

In December 2008, the FASB issued FSP SFAS No. 132R-1, “Employers’ Disclosures about Postretirement Benefit Plan Assets,” (SFAS No. 132R-1), an amendment of SFAS No. 132 (revised 2003), “Employers’ Disclosures about Pensions and Other Postretirement Benefits,” (SFAS No. 132R), which were both incorporated into ASC 715. This position required more detailed disclosures regarding defined benefit pension plan assets including investment policies and strategies, major categories of plan assets, valuation techniques used to measure the fair value of plan assets and significant concentrations of risk within plan assets. This position became effective for fiscal years ending after December 15, 2009. Upon initial application, the provisions of this position were not required for earlier periods that are presented for comparative purposes. The adoption of this statement did not have a material impact on our consolidated financial statements.

In March 2008, the FASB issued SFAS No. 161, “Disclosures about Derivative Instruments and Hedging Activities,” (SFAS No. 161), an amendment to SFAS No. 133, “Accounting for Derivative Instruments and Hedging Activities,” (SFAS No. 133), which were both incorporated into ASC 815 “Derivatives and Hedging” (ASC 815). The statement required enhanced disclosures that expand the previous disclosure requirements about an entity’s derivative instruments and hedging activities. It required more robust qualitative disclosures and expanded quantitative disclosures. This statement became effective for financial statements issued for fiscal years and interim periods beginning after November 15, 2008, with early application encouraged. We adopted the provisions of this statement on January 1, 2009, which required additional disclosure in our 2009 financial statements. The adoption of this statement did not have a material impact on our consolidated financial statements.

In December 2007, the FASB issued SFAS No. 141R, “Business Combinations,” (SFAS No. 141R), which was incorporated into ASC 805 “Business Combinations” (ASC 805). This statement required the acquiring entity in a business combination to recognize all (and only) the assets acquired and liabilities assumed in the transaction, established the acquisition-date fair value as the measurement objective for all assets acquired and liabilities assumed, and required additional disclosures by the acquirer. Under this statement, all business combinations are accounted for by applying the acquisition method. This statement became effective for us on January 1, 2009. Earlier application was prohibited. The effect of the adoption of this statement on our consolidated financial statements will be on adjustments made to pre-acquisition Pioneer income tax contingencies, which will no longer be reflected as an adjustment to goodwill but recognized through income tax expense.

In December 2007, the FASB issued SFAS No. 160, “Noncontrolling Interests in Consolidated Financial Statements,” (SFAS No. 160), which was incorporated into ASC 810. This statement required noncontrolling interests (previously referred to as minority interests) to be treated as a separate component of equity, not as a liability or other item outside of permanent equity. The statement applied to the accounting for noncontrolling interests and transactions with noncontrolling interest holders in consolidated financial statements. This statement became effective for us on January 1, 2009. Earlier application was prohibited. This statement was applied prospectively to all noncontrolling interests, including any that arose before the effective date except that comparative period information must be recast to classify noncontrolling interests in equity, attribute net income and other comprehensive income to noncontrolling interests, and provide additional required disclosures. The adoption of this statement did not have a material effect on our consolidated financial statements.

In September 2006, the FASB issued SFAS No. 157, “Fair Value Measurements,” (SFAS No. 157), which was incorporated into ASC 820. This statement did not require any new fair value measurements, but rather, it provided enhanced guidance to other pronouncements that require or permit assets or liabilities to be measured at fair value. The changes to current practice resulting from the application of this statement related to the definition of fair value, the methods used to estimate fair value, and the requirement for expanded disclosures about estimates of fair value. This statement became effective for fiscal years beginning after November 15, 2007, and interim periods within those fiscal years. The effective date for this statement for all nonfinancial assets and nonfinancial liabilities, except for items that are recognized or disclosed at fair value in the financial statements on a recurring basis was delayed by one year. Nonfinancial assets and nonfinancial liabilities that were impacted by this deferral included assets and liabilities initially measured at fair value in a business combination, and intangible assets and goodwill tested annually for impairment. We adopted the provisions of this statement related to financial assets and financial liabilities on January 1, 2008, which required additional disclosure in our financial statements. The partial adoption of this statement did not have a material impact on our consolidated financial statements. We adopted the remaining provisions of this statement related to nonfinancial assets and nonfinancial liabilities on January 1, 2009. The adoption of the remaining provisions of this statement did not have a material impact on our consolidated financial statements.

DERIVATIVE FINANCIAL INSTRUMENTS

ASC 815, formerly SFAS No. 133, required an entity to recognize all derivatives as either assets or liabilities in the statement of financial position and measure those instruments at fair value. We use hedge accounting treatment for substantially all of our business transactions whose risks are covered using derivative instruments. The accounting treatment of changes in fair value is dependent upon whether or not a derivative instrument is designated as a hedge and, if so, the type of hedge. For derivatives designated as a fair value hedge, the changes in the fair value of both the derivative and the hedged item are recognized in earnings. For derivatives designated as a cash flow hedge, the change in fair value of the derivative is recognized in other comprehensive loss until the hedged item is recognized in earnings. Ineffective portions are recognized currently in earnings. Unrealized gains and losses on derivatives not qualifying for hedge accounting are recognized currently in earnings. All derivatives recognized in earnings impact the expense line item on our consolidated statement of operations that is consistent with the nature of the underlying hedged item.

We enter into forward sales and purchase contracts to manage currency risk resulting from purchase and sale commitments denominated in foreign currencies (principally Canadian dollar and Euro). All of the currency derivatives expire within two years and are for United States dollar equivalents. At December 31, 2009, we had forward contracts to sell foreign currencies with a fair value of $0.3 million and forward contracts to buy foreign currencies with a fair value of $1.7 million. At December 31, 2008, we had no forward contracts to buy or to sell foreign currencies.

We use cash flow hedges for certain raw material and energy costs such as copper, zinc, lead, and natural gas to provide a measure of stability in managing our exposure to price fluctuations associated with forecasted purchases of raw materials and energy costs used in our manufacturing process. For derivative instruments that are designated and qualify as a cash flow hedge, the change in fair value of the derivative is recognized as a component of other comprehensive loss until the hedged item is recognized into earnings. Gains and losses on the derivatives representing hedge ineffectiveness are recognized currently in earnings. Losses on settled futures contracts were $20.4 million, ($12.5 million, net of taxes) and $8.1 million, ($5.0 million, net of taxes) in 2009 and 2008, respectively, which were included in cost of goods sold. Gains on settled futures contracts were $23.4 million, ($14.3 million, net of taxes), in 2007, which were included in cost of goods sold. At December 31, 2009, we had open positions in futures contracts through 2013 totaling $61.4 million (2008—$84.0 million). If all open futures contracts had been settled on December 31, 2009, we would have recognized a pretax gain of $18.7 million.

At December 31, 2009, accumulated other comprehensive loss included a gain, net of taxes, in fair value on commodity forward contracts of $11.6 million. If commodity prices were to remain at the levels they were at December 31, 2009, approximately $7.7 million of deferred gains, net of tax, would be reclassified into earnings during the next twelve months. The actual effect on earnings will be dependent on commodity prices when the forecasted transactions occur. At December 31, 2008, accumulated other comprehensive loss included a loss, net of taxes, in fair value on commodity forward contracts of $25.0 million.

We use interest rate swaps as a means of managing interest expense and floating interest rate exposure to optimal levels. The accounting for gains and losses associated with changes in fair value of the derivative and the effect on the consolidated financial statements will depend on the hedge designation and whether the hedge is effective in offsetting changes in fair value of cash flows of the asset or liability being hedged. For derivative instruments that are designated and qualify as a fair value hedge, 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 earnings. We include the gain or loss on the hedged items (fixed-rate borrowings) in the same line item, interest expense, as the offsetting loss or gain on the related interest rate swaps. As of December 31, 2009 and December 31, 2008, the total notional amount of our interest rate swaps designated as fair value hedges were $26.6 million and $101.6 million, respectively.

In 2001 and 2002, we entered into interest rate swaps on $75 million of our underlying fixed-rate debt obligations, whereby we agreed to pay variable rates to a counterparty who, in turn, pays us fixed rates. In January 2009, we entered into a $75 million fixed interest rate swap with equal and opposite terms as the $75 million variable interest rate swaps on the 2011 Notes. We have agreed to pay a fixed rate to a counterparty who, in turn, pays us variable rates. The result was a gain of $7.9 million on the $75 million variable interest rate swaps, which will be recognized through 2011. In January 2009, we de-designated our $75 million interest rate swaps that had previously been designated as fair value hedges. The $75 million variable interest rate swaps and the $75 million fixed interest rate swap do not meet the criteria for hedge accounting. All changes in the fair value of these interest rate swaps are recorded currently in earnings.

The fair value of our derivative asset and liability balances were:

	December 31,
	2009		2008
	($ in millions)
Other current assets	$	17.5	$	―
Other assets		7.4		11.3
Total derivative asset	$	24.9	$	11.3
Accrued liabilities	$	0.1	$	40.9
Other liabilities		0.9		―
Long-term debt		6.9		11.3
Total derivative liability	$	7.9	$	52.2

The ineffective portion of changes in fair value resulted in $0.1 million, zero and $(0.1) million credited (charged) to earnings for the years ended December 31, 2009, 2008 and 2007, respectively.

Our foreign currency forward contracts, certain commodity derivatives, and our $75 million fixed and variable interest rate swaps did not meet the criteria to qualify for hedge accounting. The effect on operating results of items not qualifying for hedge accounting was a charge of $2.7 million for 2009 and zero for 2008 and 2007.

Item 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Energy costs including electricity used in our Chlor Alkali Products segment, and certain raw materials and energy costs, namely copper, lead, zinc, electricity, and natural gas used primarily in our Winchester segment are subject to price volatility. Depending on market conditions, we may enter into futures contracts and put and call option contracts in order to reduce the impact of commodity price fluctuations. As of December 31, 2009, we maintained open positions on futures contracts totaling $61.4 million ($84.0 million at December 31, 2008). Assuming a hypothetical 10% increase in commodity prices, which are currently hedged, we would experience a $6.1 million ($8.4 million at December 31, 2008) increase in our cost of inventory purchased, which would be substantially offset by a corresponding increase in the value of related hedging instruments.

We are exposed to changes in interest rates primarily as a result of our investing and financing activities. The effect of interest rates on investing activity is not material to our consolidated financial position, results of operations, or cash flows. Our current debt structure is used to fund business operations, and commitments from banks under our senior revolving credit facility and our Accounts Receivable Facility are sources of liquidity. As of December 31, 2009, we had long-term borrowings of $398.4 million ($252.4 million at December 31, 2008) of which $4.7 million ($3.1 million at December 31, 2008) was issued at variable rates. As a result of our fixed-rate financings, we entered into floating interest rate swaps in order to manage interest expense and floating interest rate exposure to optimal levels. We have entered into $26.6 million of such swaps, whereby we agree to pay variable rates to a counterparty who, in turn, pays us fixed rates. The counterparty to these agreements is Citibank, N.A., a major financial institution. In all cases the underlying index for the variable rates is six-month London InterBank Offered Rate (LIBOR). Accordingly, payments are settled every six months and the terms of the swaps are the same as the underlying debt instruments.

In 2001 and 2002, we entered into interest rate swaps on $75 million of our underlying fixed-rate debt obligations, whereby we agreed to pay variable rates to a counterparty who, in turn, pays us fixed rates. The counterparty to these agreements is Citibank, N.A., a major financial institution. In January 2009, we entered into a $75 million fixed interest rate swap with equal and opposite terms as the $75 million variable interest rate swaps on the 2011 Notes. We have agreed to pay a fixed rate to a counterparty who, in turn, pays us variable rates. The counterparty to this agreement is Bank of America, a major financial institution. The result was a gain of $7.9 million on the $75 million variable interest rate swaps, which will be recognized through 2011. In January 2009, we de-designated our $75 million interest rate swaps that had previously been designated as fair value hedges. The $75 million variable interest rate swaps and the $75 million fixed interest rate swap do not meet the criteria for hedge accounting. All changes in the fair value of these interest rate swaps are recorded currently in earnings.

Assuming no changes in the $31.3 million of variable-rate debt levels from December 31, 2009, we estimate that a hypothetical change of 100-basis points in the LIBOR interest rates from 2009 would impact annual interest expense by $0.3 million.

The following table reflects the swap activity related to certain debt obligations:

Underlying Debt Instrument	Swap Amount		Date of Swap	December 31, 2009
	($ in millions)			Olin Pays Floating Rate:
9.125%, due 2011	$	50.0	December 2001	3.92	%
9.125%, due 2011	$	25.0	March 2002	3-4	%(a)
Industrial development and environmental improvement obligations at interest rates of 6.625% to 6.75%, due 2016-2017	$	21.1	March 2002	0.89	%
	$	5.5	March 2002	1.03	%
				Olin Receives Floating Rate:
9.125%, due 2011	$	75.0	January 2009	7.35	%

(a)	Actual rate is set in arrears. We project the rate will fall within the range shown.

These interest rate swaps reduced interest expense by $5.1 million, $2.5 million and $0.6 million in 2009, 2008 and 2007, respectively.

If the actual change in interest or commodities pricing is substantially different than expected, the net impact of interest rate risk or commodity risk on our cash flow may be materially different than that disclosed above.

We do not enter into any derivative financial instruments for speculative purposes.

Item 8. CONSOLIDATED FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

MANAGEMENT REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

The management of Olin Corporation is responsible for establishing and maintaining adequate internal control over financial reporting. Olin’s internal control system was designed to provide reasonable assurance to the company’s management and board of directors regarding the preparation and fair presentation of published financial statements.

All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation, and may not prevent or detect all misstatements.

The management of Olin Corporation has assessed the effectiveness of the company’s internal control over financial reporting as of December 31, 2009. In making this assessment, we used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control—Integrated Framework to guide our analysis and assessment. Based on our assessment as of December 31, 2009, the company’s internal control over financial reporting was effective based on those criteria.

Our independent registered public accountants, KPMG LLP, have audited and issued a report on our internal controls over financial reporting, which appears in this Form 10-K.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders of Olin Corporation:

We have audited the accompanying consolidated balance sheets of Olin Corporation and subsidiaries as of December 31, 2009 and 2008, and the related consolidated statements of operations, shareholders’ equity and cash flows for each of the years in the three-year period ended December 31, 2009. We also have audited Olin Corporation’s internal control over financial reporting as of December 31, 2009, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Olin Corporation’s management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on these consolidated financial statements and an opinion on the Company's internal control over financial reporting based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the consolidated financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

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

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Olin Corporation and subsidiaries as of December 31, 2009 and 2008, and the results of their operations and their cash flows for each of the years in the three-year period ended December 31, 2009, in conformity with U.S. generally accepted accounting principles. Also in our opinion, Olin Corporation maintained, in all material respects, effective internal control over financial reporting as of December 31, 2009, based on criteria established in Internal Control - Integrated Framework issued by the COSO.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

DESCRIPTION OF BUSINESS

Olin Corporation is a Virginia corporation, incorporated in 1892. We are a manufacturer concentrated in two business segments: Chlor Alkali Products and Winchester. Chlor Alkali Products, with nine U.S. manufacturing facilities and one Canadian manufacturing facility, produces chlorine and caustic soda, sodium hydrosulfite, hydrochloric acid, hydrogen, bleach products and potassium hydroxide. Winchester, with its principal manufacturing facility in East Alton, IL, produces and distributes sporting ammunition, reloading components, small caliber military ammunition and components, and industrial cartridges.

On October 15, 2007, we announced we entered into a definitive agreement to sell the Metals business to Global. The transaction closed on November 19, 2007. Accordingly, for all periods presented prior to the sale, Metals' operating results and cash flows are reported as discontinued operations in the consolidated statements of operations and consolidated statements of cash flows, respectively.

On August 31, 2007 we acquired Pioneer, whose operating results are included in the accompanying consolidated financial statements since the date of acquisition.

ACCOUNTING POLICIES

The preparation of the consolidated financial statements requires estimates and assumptions that affect amounts reported and disclosed in the financial statements and related notes. Actual results could differ from those estimates.

Basis of Presentation

The consolidated financial statements include the accounts of Olin Corporation and all majority-owned subsidiaries. Investment in our 50% owned affiliate and other affiliates are accounted for on the equity method. Accordingly, we include only our share of earnings or losses of these affiliates in consolidated net income. Certain reclassifications were made to prior year amounts to conform to the 2009 presentation. In 2009, the December 31, 2008 goodwill amount was reduced by $1.6 million, which reflected a reclassification of deferred taxes associated with the resolution of a Canadian capital tax matter.

We have evaluated all subsequent events through February 24, 2010, which represents the filing date of this Form 10-K with the SEC, to ensure that this Form 10-K includes subsequent events that should be recognized in the consolidated financial statements as of December 31, 2009, and appropriate disclosure of subsequent events, which were not recognized in the consolidated financial statements.

Revenue Recognition

Revenues are recognized on sales of product at the time the goods are shipped and the risks of ownership have passed to the customer. Shipping and handling fees billed to customers are included in sales. Allowances for estimated returns, discounts and rebates are recognized when sales are recorded and are based on various market data, historical trends and information from customers. Actual returns, discounts and rebates have not been materially different from estimates.

Cost of Goods Sold and Selling and Administration Expenses

Cost of goods sold includes the costs of inventory sold, related purchasing, distribution and warehousing costs, costs incurred for shipping and handling, depreciation and amortization expense related to these activities, and environmental remediation costs and recoveries. Selling and administration expenses include personnel costs associated with sales, marketing and administration, research and development, legal and legal-related costs, consulting and professional services fees, advertising expenses, depreciation expense related to these activities and other similar costs and foreign currency translation.

Other Operating Income

Other operating income consists of miscellaneous operating income items, which are related to our business activities, and gains (losses) on disposition of property, plant and equipment. Other operating income for 2009 included a $3.7 million gain on the sale of land, a $1.2 million gain on the disposition of a former manufacturing facility and $1.6 million of gains on the disposal of assets primarily associated with the St. Gabriel, LA facility conversion and expansion project. Other operating income for 2009 also included $1.0 million for a portion of a 2007 gain realized on an intangible asset sale in Chlor Alkali Products, which is recognized ratably through 2012, $0.8 million for the sale of other assets and $0.4 million for a portion of a gain realized on the sale of equipment, which was recognized ratably through June 2009. Other operating income for 2008 included $1.0 million for a portion of a 2007 gain realized on an intangible asset sale in Chlor Alkali Products, which is recognized ratably through 2012, $0.9 million for a portion of a gain realized on the sale of equipment, which is recognized ratably through June 2009, and $0.2 million of a gain on the disposition of land associated with a former manufacturing facility. These gains were partially offset by a loss of $0.9 million on the disposition of property, plant and equipment. Other operating income for 2007 included the receipt of a $1.3 million contingent payment associated with a 1995 divestiture and $0.6 million for a portion of a 2007 gain realized on an intangible asset sale in Chlor Alkali Products, which is be recognized ratably through 2012.

Other Income (Expense)

Other income (expense) consists of non-operating income items which are not related to our primary business activities. Other income (expense) for 2008 included an impairment charge of the full value of a $26.6 million investment in corporate debt securities.

Foreign Currency Translation

The functional currency for our Canadian chlor alkali subsidiary is the U.S. dollar; accordingly, gains and losses resulting from balance sheet translations are included in selling and administration. Other foreign affiliates’ balance sheet amounts are translated at the exchange rates in effect at year-end, and operations statement amounts are translated at the average rates of exchange prevailing during the year. Translation adjustments are included in accumulated other comprehensive loss.

Cash and Cash Equivalents

All highly liquid investments, with a maturity of three months or less at the date of purchase, are considered to be cash equivalents.

Short-Term Investments

We classify our marketable securities as available-for-sale, which are reported at fair market value with unrealized gains and losses included in accumulated other comprehensive loss, net of applicable taxes. The fair value of marketable securities is determined by quoted market prices. Realized gains and losses on sales of investments, as determined on the specific identification method, and declines in value of securities judged to be other-than-temporary are included in other income (expense) in the consolidated statements of operations. Interest and dividends on all securities are included in interest income and other income (expense), respectively.

Allowance for Doubtful Accounts Receivable

We evaluate the collectibility of accounts receivable based on a combination of factors. We estimate an allowance for doubtful accounts as a percentage of net sales based on historical bad debt experience. This estimate is periodically adjusted when we become aware of a specific customer's inability to meet its financial obligations (e.g., bankruptcy filing) or as a result of changes in the overall aging of accounts receivable. While we have a large number of customers that operate in diverse businesses and are geographically dispersed, a general economic downturn in any of the industry segments in which we operate could result in higher than expected defaults, and, therefore, the need to revise estimates for the provision for doubtful accounts could occur.

Inventories

Inventories are valued at the lower of cost or market, with cost being determined principally by the dollar value last-in, first-out (LIFO) method of inventory accounting. Cost for other inventories has been determined principally by the average-cost (primarily operating supplies, spare parts and maintenance parts) method. Elements of costs in inventories include raw materials, direct labor and manufacturing overhead.

Property, Plant and Equipment

Property, plant and equipment are recorded at cost. Depreciation is computed on a straight-line basis over the estimated useful lives of the related assets. Interest costs incurred to finance expenditures for major long-term construction projects are capitalized as part of the historical cost and included in property, plant and equipment and are depreciated over the useful lives of the related assets. Leasehold improvements are amortized over the term of the lease or the estimated useful life of the improvement, whichever is shorter. Start-up costs are expensed as incurred. Expenditures for maintenance and repairs are charged to expense when incurred while the costs of significant improvements, which extend the useful life of the underlying asset, are capitalized.

Property, plant and equipment are reviewed for impairment when conditions indicate that the carrying values of the assets may not be recoverable. Such impairment conditions include an extended period of idleness or a plan of disposal. If such impairment indicators are present or other factors exist that indicate that the carrying amount of an asset may not be recoverable, we determine whether impairment has occurred through the use of an undiscounted cash flow analysis at the lowest level for which identifiable cash flows exist. The amount of impairment loss, if any, is measured by the difference between the net book value of the assets and the estimated fair value of the related assets.

Asset Retirement Obligations

We record the fair value of an asset retirement obligation associated with the retirement of a tangible long-lived asset as a liability in the period incurred. The liability is measured at discounted fair value and is adjusted to its present value in subsequent periods as accretion expense is recorded. The corresponding asset retirement costs are capitalized as part of the carrying amount of the related long-lived asset and depreciated over the asset’s useful life. Asset retirement obligations are reviewed annually in the fourth quarter and/or when circumstances or other events indicate that changes underlying retirement assumptions may have occurred.

The activity of our asset retirement obligation was as follows:

	December 31,
	2009			2008
	($ in millions)
Beginning balance	$	72.1		$	71.4
Accretion		5.0			5.1
Spending		(10.9	)		(6.2	)
Currency translation adjustments		1.3			(1.7	)
Pioneer acquisition		―			4.5
Adjustments		2.7			(1.0	)
Ending balance	$	70.2		$	72.1

At December 31, 2009 and 2008, our consolidated balance sheets included an asset retirement obligation of $53.1 million and $46.6 million, respectively, which were classified as other noncurrent liabilities.

In 2009, we had net adjustments that increased the asset retirement obligation by $2.7 million, which were primarily comprised of increases in estimated costs for certain assets.

In 2008, we had net adjustments that decreased the asset retirement obligation by $1.0 million. These adjustments were primarily comprised of a decrease in the estimated liabilities by $2.9 million, primarily based on a higher probability of reducing the retirement obligation at a former chemical location than was previously assessed, partially offset by an increase of $1.9 million in estimated costs for certain assets.

Comprehensive Income (Loss)

Accumulated other comprehensive loss consists of foreign currency translation adjustments, pension and postretirement liability adjustments, amortization of prior service costs and actuarial losses net unrealized gains (losses) on derivative contracts, and net unrealized gains (losses) on marketable securities. We do not provide for U.S. income taxes on foreign currency translation adjustments since we do not provide for such taxes on undistributed earnings for foreign subsidiaries.

Goodwill

We use a discounted cash flow approach “income approach” to develop the estimated fair value of a reporting unit. Management judgment is required in developing the assumptions for the discounted cash flow model. We also corroborate our discounted cash flow analysis by evaluating a market-based approach that considers earnings before interest, taxes, depreciation and amortization (EBITDA) multiples from a representative sample of comparable public companies in the chemical industry. An impairment would be recorded if the carrying amount exceeded the estimated fair value.

All of our recorded goodwill, which is associated with acquisitions, is included in the Chlor Alkali Products segment. Given the economic environment and the uncertainties regarding the impact on our business, there can be no assurance that our estimates and assumptions, made for purposes of our goodwill impairment testing during the fourth quarter of 2009, will prove to be an accurate prediction of the future. If our assumptions regarding forecasted sales or gross margins are not achieved, we may be required to record goodwill impairment charges in future periods. It is not possible at this time to determine if any such future impairment charge would result or, if it does, whether such charge would be material.

Other Assets

Included in other assets were the following:

	December 31,
	2009		2008
	($ in millions)
Investments in non-consolidated affiliates	$	19.6	$	19.0
Intangible assets (less accumulated amortization of $3.5 million and $2.0 million, respectively)		16.7		18.2
Deferred debt issuance costs		17.4		16.3
Interest rate swaps		7.4		11.3
Other		9.9		6.0
Other assets	$	71.0	$	70.8

The August 31, 2007 valuation of identifiable intangible assets that were obtained from the Pioneer acquisition included $19.0 million associated with customers, customer contracts and relationships, and $1.2 million associated with internally developed and purchased software. These assets will be amortized over fifteen years and five years, respectively, on a straight-line basis. Amortization expense was $1.5 million in both 2009 and 2008. Intangible assets are reviewed annually in the fourth quarter and/or when circumstances or other events indicate that impairment may have occurred.

Environmental Liabilities and Expenditures

Accruals (charges to income) 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 upon current law and existing technologies. These amounts, which are not discounted and are exclusive of claims against third parties, are adjusted periodically as assessment and remediation efforts progress or additional technical or legal information becomes available. Environmental costs are capitalized if the costs increase the value of the property and/or mitigate or prevent contamination from future operations.

Discontinued Operations

We present the results of operations, financial position and cash flows that have either been sold or that meet the criteria for "held for sale" accounting as discontinued operations. At the time an operation qualifies for “held for sale” accounting, the operation is evaluated to determine whether or not the carrying value exceeds its fair value less cost to sell. Any loss as a result of carrying value in excess of fair value less cost to sell is recorded in the period the operation meets “held for sale” accounting. Management judgment is required to assess the criteria required to meet “held for sale” accounting, and estimate fair value. Changes to the operation could cause it to no longer qualify for “held for sale” accounting and changes to fair value could result in an increase or decrease to previously recognized losses.

Income Taxes

Deferred taxes are provided for differences between the financial statement and tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. A valuation allowance is provided to offset deferred tax assets if, based on the available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized.

Derivative Financial Instruments

We are exposed to market risk in the normal course of our business operations due to our purchases of certain commodities, our ongoing investing and financing activities, and our operations that use foreign currencies. The risk of loss can be assessed from the perspective of adverse changes in fair values, cash flows and future earnings. We have established policies and procedures governing our management of market risks and the use of financial instruments to manage exposure to such risks. We use hedge accounting treatment for substantially all of our business transactions whose risks are covered using derivative instruments. The hedge accounting treatment provides for the deferral of gains or losses (included in other comprehensive loss) on derivative instruments until such time as the related transactions occur.

Concentration of Credit Risk

Accounts receivable is the principal financial instrument which subjects us to a concentration of credit risk. Credit is extended based upon the evaluation of a customer’s financial condition and, generally, collateral is not required. Concentrations of credit risk with respect to receivables are somewhat limited due to our large number of customers, the diversity of these customers’ businesses and the geographic dispersion of such customers. The majority of our accounts receivable are derived from sales denominated in U.S. dollars. We maintain an allowance for doubtful accounts based upon the expected collectibility of all trade receivables.

Fair Value

Fair value is defined as the price at which an asset could be exchanged in a current transaction between knowledgeable, willing parties or the amount that would be paid to transfer a liability to a new obligor, not the amount that would be paid to settle the liability with the creditor. Where available, fair value is based on observable market prices or parameters or derived from such prices or parameters. Where observable prices or inputs are not available, valuation models are applied. These valuation techniques involve some level of management estimation and judgment, the degree of which is dependent on the price transparency for the instruments or market and the instruments’ complexity.

o	Level 1 — Inputs were unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date.

o	Level 2 — Inputs (other than quoted prices included in Level 1) were either directly or indirectly observable for the asset or liability through correlation with market data at the measurement date and for the duration of the instrument’s anticipated life.

o	Level 3 — Inputs reflected management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. Consideration was given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model.

Retirement-Related Benefits

We account for our defined benefit pension plans and non-pension postretirement benefit plans using actuarial models required by ASC 715, formerly SFAS No. 87 and SFAS No. 106, respectively. These models use an attribution approach that generally spreads the financial impact of changes to the plan and actuarial assumptions over the average remaining service lives of the employees in the plan. Changes in liability due to changes in actuarial assumptions such as discount rate, rate of compensation increases and mortality, as well as annual deviations between what was assumed and what was experienced by the plan are treated as gains or losses. The principle underlying the required attribution approach is that employees render service over their average remaining service lives on a relatively smooth basis and, therefore, the accounting for benefits earned under the pension or non-pension postretirement benefits plans should follow the same relatively smooth pattern. With the closure of our defined benefit pension plan to new entrants, the freezing of our domestic defined benefit pension plan for salaried and certain non-bargained hourly employees that became effective January 1, 2008 and the sale of the Metals business, substantially all defined benefit pension plan participants beginning in 2008 were inactive; therefore, actuarial gains and losses are now being amortized based upon the remaining life expectancy of the inactive plan participants rather than the future service period of the active participants, which was the amortization period used prior to 2008. For the year ended December 31, 2007, the average remaining life expectancy of the inactive participants in the defined benefit pension plan was 19 years; compared to the average remaining service lives of the active employees in the defined benefit pension plan of 10.7 years. For the years ended December 31, 2009 and 2008, the average remaining life expectancy of the inactive participants in the defined benefit pension plan was 19 years.

One of the key assumptions for the net periodic pension calculation is the expected long-term rate of return on plan assets, used to determine the “market-related value of assets.” The “market-related value of assets” recognizes differences between the plan’s actual return and expected return over a five year period. The required use of an expected long-term rate of return on the market-related value of plan assets may result in a recognized pension income that is greater or less than the actual returns of those plan assets in any given year. Over time, however, the expected long-term returns are designed to approximate the actual long-term returns and, therefore, result in a pattern of income and expense recognition that more closely matches the pattern of the services provided by the employees. As differences between actual and expected returns are recognized over five years, they subsequently generate gains and losses that are subject to amortization over the average remaining life expectancy of the inactive plan participants, as described in the preceding paragraph.

Stock-Based Compensation

We measure the cost of employee services received in exchange for an award of equity instruments, such as stock options, performance shares, and restricted stock, based on the grant-date fair value of the award. This cost is recognized over the period during which an employee is required to provide service in exchange for the award, the requisite service period (usually the vesting period). An initial measurement is made of the cost of employee services received in exchange for an award of liability instruments based on its current fair value and the value of that award is subsequently remeasured at each reporting date through the settlement date. Changes in fair value of liability awards during the requisite service period are recognized as compensation cost over that period.

The fair value of each option granted, which typically vests ratably over three years, but not less than one year, was estimated on the date of grant, using the Black-Scholes option-pricing model with the following weighted-average assumptions used:

	2009			2008			2007
Dividend yield		4.26	%		4.34	%		4.37	%
Risk-free interest rate		2.32	%		3.21	%		4.81	%
Expected volatility		40	%		32	%		35	%
Expected life (years)		7.0			7.0			7.0
Grant fair value (per option)	$	3.85		$	4.52		$	4.46
Exercise price	$	14.28		$	20.29		$	16.52
Shares granted		866,250			523,350			739,550

Dividend yield was based on a historical average. Risk-free interest rate was based on zero coupon U.S. Treasury securities rates for the expected life of the options. Expected volatility was based on our historical stock price movements, and we believe that historical experience is the best available indicator of the expected volatility. Expected life of the option grant was based on historical exercise and cancellation patterns, and we believe that historical experience is the best estimate for future exercise patterns.

RECENT ACCOUNTING PRONOUNCEMENTS

In January 2010, the FASB issued ASU 2010-06, which amends ASC 820. This update adds new fair value disclosure requirements about transfers into and out of Level 1 and 2 and separate disclosures about purchases, sales, issuances, and settlements related to Level 3 measurements. This update expands disclosures on valuation techniques and inputs used to measure fair value. This update is effective for fiscal years beginning after December 15, 2009, except for the requirement to provide the Level 3 activity of purchases, sales, issuances, and settlements, which will be effective for fiscal years beginning after December 15, 2010. We will adopt the provisions of ASU 2010-06 in 2010, except for the requirement to provide the additional Level 3 activity, which will be adopted in 2011. This update will require additional disclosure in our first quarter 2010 condensed financial statements. The adoption of this update will not have a material effect on our consolidated financial statements.

In July 2009, the FASB issued the Codification, which was incorporated into ASC 105. The Codification will be the single source of authoritative U.S. generally accepted accounting principles. The Codification does not change generally accepted accounting principles, but is intended to make it easier to find and research issues. The Codification introduces a new structure that takes accounting pronouncements and organizes them by approximately 90 accounting topics. The Codification was effective for interim and fiscal years ending after September 15, 2009. We adopted the Codification on July 1, 2009. The adoption of this statement did not have a material effect on our consolidated financial statements but changed our reference to generally accepted accounting principles beginning in the third quarter of 2009.

In June 2009, the FASB issued SFAS No. 166, which was incorporated into ASC 860, and SFAS No. 167, which was incorporated into ASC 810. These statements changed the way entities account for securitizations and special-purpose entities. The new standards eliminate existing exceptions, strengthen the standards relating to securitizations and special-purpose entities, and enhance disclosure requirements. Both of these statements are effective for fiscal years beginning after November 15, 2009. The adoption of these statements will not have a material effect on our consolidated financial statements.

In May 2009, the FASB issued SFAS No. 165, which was incorporated into ASC 855. ASC 855 provides guidance on management’s assessment of subsequent events. The statement is not expected to significantly change practice because its guidance is similar to that in American Institute of Certified Public Accountants Professional Standards U.S. Auditing Standards Section 560, “Subsequent Events,” with some modifications. This statement became effective for us on June 15, 2009. The adoption of this statement did not have a material effect on our consolidated financial statements.

In April 2009, the FASB issued three FSP’s intended to provide additional application guidance and enhance disclosures regarding fair value measurements and impairments of securities. SFAS No. 157-4 provided guidelines for making fair value measurements more consistent with the principles presented in ASC 820. SFAS No. 107-1 and APB 28-1, which were incorporated into ASC 825, enhanced consistency in financial reporting by increasing the frequency of fair value disclosures. SFAS No. 115-2 and SFAS No. 124-2, which were incorporated into ASC 320, provided additional guidance designed to create greater clarity and consistency in accounting for and presenting impairment losses on securities.

In December 2008, the FASB issued SFAS No. 132R-1, an amendment of SFAS No. 132R, which was incorporated into ASC 715. This position required more detailed disclosures regarding defined benefit pension plan assets including investment policies and strategies, major categories of plan assets, valuation techniques used to measure the fair value of plan assets and significant concentrations of risk within plan assets. This position became effective for fiscal years ending after December 15, 2009. Upon initial application, the provisions of this position were not required for earlier periods that are presented for comparative purposes. The adoption of this statement did not have a material impact on our consolidated financial statements.

In March 2008, the FASB issued SFAS No. 161, an amendment to SFAS No. 133, which were both incorporated into ASC 815. The statement required enhanced disclosures that expand the previous disclosure requirements about an entity’s derivative instruments and hedging activities. It required more robust qualitative disclosures and expanded quantitative disclosures. This statement became effective for financial statements issued for fiscal years and interim periods beginning after November 15, 2008, with early application encouraged. We adopted the provisions of this statement on January 1, 2009, which required additional disclosure in our 2009 financial statements. The adoption of this statement did not have a material impact on our consolidated financial statements.

In December 2007, the FASB issued SFAS No. 141R, which was incorporated into ASC 805. This statement required the acquiring entity in a business combination to recognize all (and only) the assets acquired and liabilities assumed in the transaction, established the acquisition-date fair value as the measurement objective for all assets acquired and liabilities assumed, and required additional disclosures by the acquirer. Under this Statement, all business combinations are accounted for by applying the acquisition method. This statement became effective for us on January 1, 2009. Earlier application was prohibited. The effect of the adoption of this statement on our consolidated financial statements will be on adjustments made to pre-acquisition Pioneer income tax contingencies, which will no longer be reflected as an adjustment to goodwill but recognized through income tax expense.

In December 2007, the FASB issued SFAS No. 160, which was incorporated into ASC 810. This statement required noncontrolling interests (previously referred to as minority interests) to be treated as a separate component of equity, not as a liability or other item outside of permanent equity. The statement applied to the accounting for noncontrolling interests and transactions with noncontrolling interest holders in consolidated financial statements. This statement became effective for us on January 1, 2009. Earlier application was prohibited. This statement was applied prospectively to all noncontrolling interests, including any that arose before the effective date except that comparative period information must be recast to classify noncontrolling interests in equity, attribute net income and other comprehensive income to noncontrolling interests, and provide additional required disclosures. The adoption of this statement did not have a material effect on our consolidated financial statements.

In September 2006, the FASB issued SFAS No. 157, which was incorporated into ASC 820. This statement did not require any new fair value measurements, but rather, it provided enhanced guidance to other pronouncements that require or permit assets or liabilities to be measured at fair value. The changes to current practice resulting from the application of this statement related to the definition of fair value, the methods used to estimate fair value, and the requirement for expanded disclosures about estimates of fair value. This statement became effective for fiscal years beginning after November 15, 2007, and interim periods within those fiscal years. The effective date for this statement for all nonfinancial assets and nonfinancial liabilities, except for items that are recognized or disclosed at fair value in the financial statements on a recurring basis was delayed by one year. Nonfinancial assets and nonfinancial liabilities that were impacted by this deferral included assets and liabilities initially measured at fair value in a business combination, and intangible assets and goodwill tested annually for impairment. We adopted the provisions of this statement related to financial assets and financial liabilities on January 1, 2008, which required additional disclosure in our financial statements. The partial adoption of this statement did not have a material impact on our consolidated financial statements. We adopted the remaining provisions of this statement related to nonfinancial assets and nonfinancial liabilities on January 1, 2009. The adoption of the remaining provisions of this statement did not have a material impact on our consolidated financial statements.

ACQUISITIONS

For segment reporting purposes, Pioneer has been included in Chlor Alkali Products. Our results for 2008 and 2007 included $552.7 million and $183.6 million, respectively, of Pioneer sales and $101.9 million and $29.2 million, respectively, of Pioneer segment income.

We finalized our purchase price allocation during 2008. The adjustments to the purchase price allocation were primarily the result of finalizing estimates for environmental expenditures to investigate and remediate known sites and asset retirement obligations, partially offset by a resolution of certain tax audit issues. These adjustments resulted in no change to goodwill. The following table summarizes the final allocation of the purchase price to Pioneer’s assets and liabilities:

	August 31, 2007
	($ in millions)
Total current assets	$	222.7
Property, plant and equipment		238.1
Other assets		30.1
Goodwill		301.9
Total assets acquired		792.8
Total current liabilities		(72.6	)
Long-term debt		(147.7	)
Deferred income taxes		(14.8	)
Other liabilities		(131.6	)
Total liabilities assumed		(366.7	)
Net assets acquired	$	426.1

Included in total current assets is cash and cash equivalents of $126.4 million. Included in other liabilities are liabilities for future environmental expenditures to investigate and remediate known sites of $57.5 million, liabilities for unrecognized tax benefits of $29.3 million, accrued pension and postretirement liabilities of $15.0 million, asset retirement obligations of $23.6 million and other liabilities of $6.2 million.

During the fourth quarter of 2007, we completed our valuation of identifiable intangible assets that resulted from the Pioneer acquisition. We allocated $19.0 million of purchase price to intangible assets relating to customers, customer contracts and relationships, which management estimates to have a useful life of fifteen years, and $1.2 million to intangible assets associated with internally developed and purchased software, which management estimates to have a useful life of five years. These identifiable intangible assets were included in other assets.

Based on the valuation, $301.9 million was assigned to goodwill. In 2009, the December 31, 2008 goodwill amount was reduced by $1.6 million, which reflected a reclassification of deferred taxes associated with the resolution of a Canadian tax matter. None of the goodwill is deductible for tax purposes. The goodwill represents the portion of the purchase price that is in excess of the fair values of the other net assets acquired. The primary reason for the acquisition and the principal factors that contributed to a Pioneer purchase price that resulted in the recognition of goodwill are the cost savings available from the combination of the two businesses, the geographic diversification the Pioneer locations provide us, and the strengthened position in the industrial bleach segment. The cost-saving opportunities included the elimination of duplicate administrative activities and improved operational efficiencies in logistics, purchasing, and manufacturing.

Goodwill recorded in the acquisition is not amortized but is reviewed annually in the fourth quarter and/or when circumstances or other events indicate that impairment may have occurred.

On March 12, 2008, we announced that, in connection with our plans to streamline our Chlor Alkali Products manufacturing operations in Canada in order to serve our customer base in a more cost effective manner, we would close the acquired Dalhousie, New Brunswick, Canada chlorine, caustic soda, sodium chlorate, and bleach operations. We substantially completed the closure of the Dalhousie facility by June 30, 2008. We expect to incur cash expenditures of $2.5 million associated with the shutdown, which were previously included in current liabilities on the August 31, 2007 balance sheet. We have paid $2.2 million of costs associated with this shutdown as of December 31, 2009.

The following pro forma summary presents the condensed statement of operations as if the acquisition of Pioneer had occurred at the beginning of the period (unaudited):

	Year ended December 31,
	2007
	($ in millions, except per share data)
Sales	$	1,625.0
Income from continuing operations		116.1
Net income		6.1
Income from continuing operations per common share:
Basic	$	1.57
Diluted		1.56
Net income per common share:
Basic	$	0.08
Diluted		0.08

The pro forma statement of operations includes an increase to interest expense of $4.3 million. This adjustment is calculated assuming that our borrowings of $110.0 million at an interest rate of 5.76% at the time of the merger were outstanding from January 1, 2007. The pro forma statement of operations uses estimates and assumptions based on information available at the time. Management believes the estimates and assumptions to be reasonable; however, actual results may differ significantly from this pro forma financial information. The pro forma information does not reflect any cost savings that might be achieved from combining the operations and is not intended to reflect the actual results that would have occurred had the companies actually been combined during the period presented.

DISCONTINUED OPERATIONS

On October 15, 2007, we announced we entered into a definitive agreement to sell the Metals business to Global for $400 million, payable in cash. The price received was subject to a customary working capital adjustment. The transaction closed on November 19, 2007. We recognized a pretax loss of $160.0 million partially offset by a $21.0 million income tax benefit, resulting in a net loss on disposal of discontinued operations of $139.0 million for 2007. The loss on disposal of discontinued operations included a pension curtailment charge of $6.9 million, other postretirement benefits curtailment credit of $1.1 million, and transaction fees of $24.6 million. The final loss recognized related to this transaction did not change upon the final determination of the value of working capital in the business. The loss on the disposal, which included transaction costs, reflected a book value of the Metals business of approximately $564 million and a tax basis of approximately $396 million. The difference between the book and tax values of the business reflected primarily goodwill of $75.8 million and intangibles of $10.4 million. Based on the final working capital adjustment, we received net cash proceeds from the transaction of $380.8 million, which was in addition to the $98.1 million of after-tax cash flow realized from the operation of Metals during 2007.

In April 2008, we and Global entered into a binding arbitration regarding the final working capital adjustment. The arbitration was concluded in 2009 and resulted in a payment of $20.6 million, which was consistent with the estimated working capital adjustment we anticipated from the transaction.

The Metals business was a reportable segment comprised of principal manufacturing facilities in East Alton, IL and Montpelier, OH. Metals produced and distributed copper and copper alloy sheet, strip, foil, rod, welded tube, fabricated parts, and stainless steel and aluminum strip. Sales for the Metals business were $1,891.7 million for the period of our ownership in 2007. Intersegment sales of $81.4 million for the period of our ownership in 2007 representing the sale of ammunition cartridge case cups to Winchester from Metals, at prices that approximate market, have been eliminated from Metals sales. In conjunction with the sale of the Metals business, Winchester agreed to purchase the majority of its ammunition cartridge case cups and copper-based strip requirements from Global under a multi-year agreement with pricing, terms, and conditions which approximate market. The Metals business employed approximately 2,900 hourly and salaried employees. The results of operations from the Metals business have been presented as discontinued operations for all periods presented.

EARNINGS PER SHARE

Basic and diluted income (loss) per share are computed by dividing net income (loss) by the weighted average number of common shares outstanding. Diluted earnings per share reflect the dilutive effect of stock-based compensation.

Depreciation expense was $70.2 million, $68.1 million, and $47.3 million for 2009, 2008 and 2007, respectively. Leased assets capitalized and included above are not significant. Interest capitalized was $9.7 million, $5.0 million, and $0.2 million for 2009, 2008 and 2007, respectively. Maintenance and repairs charged to operations amounted to $135.0 million, $124.1 million, and $88.8 million in 2009, 2008 and 2007, respectively. The increase in depreciation expense and maintenance and repair charges from 2007 primarily relate to Pioneer.

The consolidated statements of cash flows for the years ended December 31, 2009 and 2008, included a $2.6 million and $(16.2) million, respectively, increase (reduction) to capital expenditures, with the corresponding change to accounts payable and accrued liabilities, related to purchases of property, plant and equipment included in accounts payable at December 31, 2009 and 2008.

INVESTMENTS—AFFILIATED COMPANIES

We have a 50% ownership interest in SunBelt which is accounted for using the equity method of accounting. Condensed financial positions and results of operations of this equity-basis affiliate in its entirety were as follows:

Gross profit		79.9		87.4		103.4
Net income		59.4		65.1		82.0

The amount of cumulative unremitted earnings of SunBelt was $3.5 million and $12.9 million at December 31, 2009 and 2008, respectively. We received distributions from SunBelt totaling $34.4 million, $29.4 million, and $35.1 million in 2009, 2008 and 2007, respectively. We have not made any contributions in 2009, 2008 or 2007.

In accounting for our ownership interest in SunBelt, we adjust the reported operating results for depreciation expense in order to conform SunBelt’s plant and equipment useful lives to ours. Beginning January 1, 2007, the original machinery and equipment of SunBelt had been fully depreciated in accordance with our useful asset lives, thus resulting in lower depreciation expense. The lower depreciation expense increased our share of SunBelt’s operating results by $3.5 million, $4.8 million and $3.8 million in 2009, 2008 and 2007, respectively. The operating results from Sunbelt included interest expense of $4.0 million, $4.4 million, and $4.8 million in 2009, 2008 and 2007, respectively, on the SunBelt Notes. Finally, we provide various administrative, management and logistical services to SunBelt for which we received fees totaling $8.4 million, $8.2 million, and $8.3 million in 2009, 2008 and 2007, respectively.

Pursuant to a note purchase agreement dated December 22, 1997, SunBelt sold $97.5 million of Guaranteed Senior Secured Notes Due 2017, Series O, and $97.5 million of Guaranteed Senior Secured Notes Due 2017, Series G. We refer to these notes as the SunBelt Notes. The SunBelt Notes bear interest at a rate of 7.23% per annum, payable semiannually in arrears on each June 22 and December 22.

We have guaranteed the Series O Notes, and PolyOne, our partner in this venture, has guaranteed the Series G Notes, in both cases pursuant to customary guarantee agreements. Our guarantee and PolyOne’s guarantee are several, rather than joint. Therefore, we are not required to make any payments to satisfy the Series G Notes guaranteed by PolyOne. An insolvency or bankruptcy of PolyOne will not automatically trigger acceleration of the SunBelt Notes or cause us to be required to make payments under our guarantee, even if PolyOne is required to make payments under its guarantee. However, if SunBelt does not make timely payments on the SunBelt Notes, whether as a result of failure to pay on a guarantee or otherwise, the holders of the SunBelt Notes may proceed against the assets of SunBelt for repayment. If we were to make debt service payments under our guarantee, we would have a right to recover such payments from SunBelt.

In addition to SunBelt, we have two other investments, which are accounted for under the equity method.

On November 16, 2007, we purchased for cash an $11.6 million equity interest in a limited liability company that owns a bleach and related chemical manufacturing facility (bleach joint venture). As part of the investment we also entered into several commercial agreements, including agreements by which we will supply raw materials and services, and we will have marketing responsibility for bleach and caustic soda.

We hold a 9.1% limited partnership interest in Bay Gas Storage Company, Ltd. (Bay Gas), an Alabama limited partnership, in which EnergySouth, Inc. (EnergySouth), which was acquired in 2008 by Sempra Energy, is the general partner with interest of 90.9%. Bay Gas owns, leases, and operates underground gas storage and related pipeline facilities, which are used to provide storage in the McIntosh, AL area and delivery of natural gas to EnergySouth customers.

DEBT

Credit Facility

On October 29, 2007, we entered into a new $220 million five-year senior revolving credit facility, which replaced the $160 million senior revolving credit facility. During the first quarter of 2008, we increased our senior revolving credit facility by $20 million to $240 million by adding a new lending institution. The new senior revolving credit facility will expire in October 2012. We have the option to expand the $240 million senior revolving credit facility by an additional $60 million by adding a maximum of two additional lending institutions each year. At December 31, 2009 we had $219.6 million available under this senior revolving credit facility, because we had issued $20.4 million of letters of credit under a $110 million subfacility. Under the senior revolving credit facility, we may select various floating rate borrowing options. The actual interest rate paid on borrowings under the senior revolving credit facility is based on a pricing grid which is dependent upon the leverage ratio as calculated under the terms of the facility at the end of the prior fiscal quarter. The facility includes various customary restrictive covenants, including restrictions related to the ratio of debt to earnings before interest expense, taxes, depreciation and amortization (leverage ratio) and the ratio of earnings before interest expense, taxes, depreciation and amortization to interest expense (coverage ratio). Compliance with these covenants is determined quarterly based on the operating cash flows for the last four quarters. We were in compliance with all covenants and restrictions under all our outstanding credit agreements as of December 31, 2009 and 2008, and no event of default had occurred that would permit the lenders under our outstanding credit agreements to accelerate the debt if not cured. In the future, our ability to generate sufficient operating cash flows, among other factors, will determine the amounts available to be borrowed under these facilities. As of December 31, 2009, there were no covenants or other restrictions that limited our ability to borrow.

At December 31, 2009, we had letters of credit of $46.7 million outstanding, of which $20.4 million were issued under our $240 million senior revolving credit facility. In addition to our senior revolving credit facility, we have a $35 million letter of credit facility. These letters of credit are used to support certain long-term debt, capital expenditure commitments, certain workers compensation insurance policies, and plant closure and post-closure obligations.

We have a $75 million, 364-day Accounts Receivable Facility, renewable annually for five years, which expires in July 2012. The Accounts Receivable Facility provides for the sale of our eligible trade receivables to a third party conduit through a wholly-owned, bankruptcy-remote, special purpose entity that is consolidated for financial statement purposes. At December 31, 2009, we had $75 million available under the Accounts Receivable Facility based on eligible trade receivables. At December 31, 2009, we had no securitized accounts receivable or the corresponding debt on the consolidated balance sheet. Interest expense under this facility was zero in 2009 and 2008 and $1.0 million for 2007. The Accounts Receivable Facility contains specific covenants relating to the ability of the lender to obtain or maintain a first priority lien on the receivables. In addition, the Accounts Receivable Facility incorporates the leverage and coverage covenants that are contained in the senior revolving credit facility.

Annual maturities of long-term debt are none in 2010, $80.5 million in 2011, none in 2012, $11.4 million in 2013, $1.8 million in 2014 and a total of $304.7 million thereafter.

As a result of our fixed-rate financings, we entered into floating interest rate swaps in order to manage interest expense and floating interest rate exposure. We have entered into swaps, as disclosed below, whereby we agree to pay variable and fixed rates to a counterparty who, in turn, pays us fixed and variable rates. In all cases the underlying index for variable rates is the six-month LIBOR. Accordingly, payments are settled every six months and the terms of the swaps are the same as the underlying debt instruments.

The following table reflects the swap activity related to certain debt obligations:

Underlying Debt Instrument	Swap Amount		Date of Swap	December 31, 2009
		($ in millions)		Olin Pays Floating Rate:
9.125%, due 2011	$	50.0	December 2001	3.92	%
9.125%, due 2011	$	25.0	March 2002	3-4	%(a)

		5.5	March 2002	1.03	%
				Olin Receives Floating Rate:
9.125%, due 2011	$	75.0	January 2009	7.35	%

(a)	Actual rate is set in arrears. We project the rate will fall within the range shown.

In 2001 and 2002, we entered into interest rate swaps on $75 million of our underlying fixed-rate debt obligations, whereby we agreed to pay variable rates to a counterparty who, in turn, pays us fixed rates. The counterparty to these agreements is Citibank, N.A., a major financial institution. In January 2009, we entered into a $75 million fixed interest rate swap with equal and opposite terms as the $75 million variable interest rate swaps on the 2011 Notes. We have agreed to pay a fixed rate to a counterparty who, in turn, pays us variable rates. The counterparty to this agreement is Bank of America, a major financial institution. The result was a gain of $7.9 million on the $75 million variable interest rate swaps, which will be recognized through 2011. As of December 31, 2009, $5.5 million of this gain was included in long-term borrowings as an increase to the carrying amount of the 2011 Notes.

The remaining $26.6 million of interest rate swaps have been designated as fair value hedges of the risk of changes in the value of our fixed-rate debt due to changes in interest rates, for a portion of our fixed-rate borrowings. Accordingly, the interest rate swaps have been recorded at their fair market value of $1.4 million at December 31, 2009 and are included in other assets on the accompanying consolidated balance sheet, with a corresponding increase in the carrying amount of the industrial development and environmental improvement obligations. No gain or loss has been recorded as the swaps meet the criteria to qualify for hedge accounting treatment with no ineffectiveness. The counterparty to these interest rate swap contracts is Citibank, N.A., a major financial institution.

Our loss in the event of nonperformance by these counterparties could be significant to our financial position and results of operations. These interest rate swaps reduced interest expense by $5.1 million, $2.5 million, and $0.6 million for 2009, 2008 and 2007, respectively. The difference between interest paid and interest received is included as an adjustment to interest expense.

PENSION PLANS

In October 2007, we announced that we were freezing our domestic defined benefit pension plan for salaried and certain non-bargained hourly employees. Affected employees were eligible to accrue pension benefits through December 31, 2007, but are not accruing any additional benefits under the plan after that date. Employee service after December 31, 2007 does count toward meeting the vesting requirements for such pension benefits and the eligibility requirements for commencing a pension benefit, but not toward the calculation of the pension benefit amount. Compensation earned after December 31, 2007 similarly does not count toward the determination of the pension benefit amounts under the defined benefit pension plan. In lieu of continuing pension benefit accruals for the affected employees under the pension plan, starting in 2008, we provide a contribution to an individual retirement contribution account maintained with the CEOP equal to 5% of the employee’s eligible compensation if such employee is less than age 45, and 7.5% of the employee’s eligible compensation if such employee is age 45 or older. Freezing the domestic defined benefit pension plan for salaried and certain non-bargained hourly employees was accounted for as a curtailment under ASC 715, formerly SFAS No. 88. As a result of freezing the domestic defined benefit plan, we recorded a curtailment charge of $1.9 million for the defined benefit pension plan and a corresponding curtailment credit of $1.9 million for the non-qualified pension plan in 2007. Beginning in 2008, most of our employees participate in defined contribution pension plans. Expenses of the defined contribution pension plans were $12.7 million, $11.3 million and $2.7 million for 2009, 2008 and 2007, respectively.

A portion of our bargaining hourly employees continue to participate in our domestic defined benefit pension plans under a flat-benefit formula. Our funding policy for the defined benefit pension plans is consistent with the requirements of federal laws and regulations. Our foreign subsidiaries maintain pension and other benefit plans, which are consistent with statutory practices. Our defined benefit pension plan provides that if, within three years following a change of control of Olin, any corporate action is taken or filing made in contemplation of, among other things, a plan termination or merger or other transfer of assets or liabilities of the plan, and such termination, merger or transfer thereafter takes place, plan benefits would automatically be increased for affected participants (and retired participants) to absorb any plan surplus (subject to applicable collective bargaining requirements).

During the third quarter of 2006, the “Pension Protection Act of 2006,” amended by “The Worker, Retiree, and Employer Recovery Act,” during the fourth quarter of 2008, became law. Among the stated objectives of the laws were the protection of both pension beneficiaries and the financial health of the PBGC. To accomplish these objectives, the new laws require sponsors to fund defined benefit pension plans earlier than previous requirements and to pay increased PBGC premiums. The laws require defined benefit pension plans to be fully funded in 2011. This will accelerate and potentially increase our pension plan funding requirements.

Under ASC 715, formerly SFAS No. 158, we recorded a $23.0 million after-tax charge ($35.0 million pretax) to shareholders’ equity as of December 31, 2009 for our pension plans. This charge reflected a 50-basis point decrease in the plans’ discount rate, partially offset by the favorable performance on plan assets during 2009. In 2008, we recorded a $103.2 million after-tax charge ($168.9 million pretax) to shareholders’ equity as of December 31, 2008 for our pension plans. This charge reflected the unfavorable performance on plan assets during 2008.

Amounts recognized in the consolidated balance sheets consisted of:

The $93.0 million actuarial loss for 2009 was the result of actuarial losses, primarily due to a 50-basis point decrease in the plans’ discount rate. The $3.1 million actuarial gain for 2008 was the result of actuarial gains due to plan experience.

At December 31, 2009 and 2008, the benefit obligation of non-qualified pension plans was $60.4 million and $56.5 million, respectively, and was included in the above pension benefit obligation. There were no plan assets for these non-qualified pension plans. Benefit payments for the non-qualified pension plans are expected to be as follows: 2010—$4.2 million; 2011—$4.0 million; 2012—$10.4 million; 2013—$4.4 million; and 2014—$3.4 million. Benefit payments for the qualified plans are projected to be as follows: 2010—$118.0 million; 2011—$108.3 million; 2012—$103.6 million; 2013—$99.6 million; and 2014—$96.1 million.

The service cost and the amortization of prior service cost components of pension expense related to the employees of the operating segments are allocated to the operating segments based on their respective estimated census data. Therefore, the allocated portion of net periodic pension benefit costs for the Metals business of $7.9 million for the period of our ownership in 2007 was included in income from discontinued operations.

In 2008, we recorded curtailment charges of $4.1 million associated with the transition of a portion of our East Alton, IL Winchester hourly workforce and our McIntosh, AL Chlor Alkali hourly workforce from a defined benefit pension plan to a defined contribution pension plan. In 2007, we recorded a defined benefit pension curtailment charge of $6.9 million related to the sale of the Metals business, which was included in the loss on disposal of discontinued operations. Also during 2007, we recorded a curtailment charge of $0.5 million resulting from the conversion of a portion of the Metals hourly workforce from a defined benefit pension plan to a defined contribution pension plan, which was included in income from discontinued operations.

Pension Plan Assumptions

Certain actuarial assumptions, such as discount rate and long-term rate of return on plan assets, have a significant effect on the amounts reported for net periodic benefit cost and accrued benefit obligation amounts. We use a measurement date of December 31 for our pension plans.

	Pension Benefits
Weighted Average Assumptions:	2009			2008			2007
Discount rate—periodic benefit cost		6.25	%		6.25	%		6.0	%
Expected return on assets		8.5	%		8.5	%		9.0	%
Rate of compensation increase		3.0	%		3.0	%		3.0	%
Discount rate—benefit obligation		5.75	%		6.25	%		6.25	%

The discount rate is based on a hypothetical yield curve represented by a series of annualized individual zero-coupon bond spot rates for maturities ranging from one-half to thirty years. The bonds used in the yield curve must have a rating of AA or better per Standard & Poor’s, be non-callable, and have at least $150 million par outstanding. The yield curve is then applied to the projected benefit payments from the plan. Based on these bonds and the projected benefit payment streams, the single rate that produces the same yield as the matching bond portfolio, rounded to the nearest quarter point, is used as the discount rate.

The long-term expected rate of return on plan assets represents an estimate of the long-term rate of returns on the investment portfolio consisting of equities, fixed income, and alternative investments. We use long-term historical actual return information, the allocation mix of investments that comprise plan assets, and forecast estimates of long-term investment returns by reference to external sources. The historic rate of return on plan assets has been 10.3% for the last 5 years, 6.8% for the last 10 years, and 10.5% for the last 15 years. The following rates of return by asset class were considered in setting the long-term rate of return assumption:

U.S. equities	9	%	to	13	%
Non-U.S. equities	10	%	to	14	%
Fixed income/cash	5	%	to	9	%
Alternative investments	5	%	to	15	%
Absolute return strategies	8	%	to	12	%

Plan Assets

Our pension plan asset allocation at December 31, 2009 and 2008, by asset class is as follows:

	Percentage of Plan Assets
Asset Class	2009			2008
U.S. equities		4	%		4	%
Non-U.S. equities		10	%		5	%
Fixed income/cash		52	%		55	%
Alternative investments		15	%		17	%
Absolute return strategies		19	%		19	%
Total		100	%		100	%

The Alternative Investments asset class includes hedge funds, real estate, and private equity investments. The Alternative Investment class is intended to help diversify risk and increase returns by utilizing a broader group of assets.

Absolute Return Strategies further diversify the plan’s assets through the use of asset allocations that seek to provide a targeted rate of return over inflation. The investment managers allocate funds within asset classes that they consider to be undervalued in an effort to preserve gains in overvalued asset classes and to find opportunities in undervalued asset classes.

A master trust was established by our pension plan to accumulate funds required to meet benefit payments of our plan and is administered solely in the interest of our plan’s participants and their beneficiaries. The master trust’s investment horizon is long term. Its assets are managed by professional investment managers or invested in professionally managed investment vehicles.

Our pension plan maintains a portfolio of assets designed to achieve an appropriate risk adjusted return. The portfolio of assets is also structured to protect the funding level from the negative impacts of interest rate changes on the asset and liability values. This is accomplished by investing in a portfolio of assets with a maturity duration that approximately matches the duration of the plan liabilities. Risk is managed by diversifying assets across asset classes whose return patterns are not highly correlated, investing in passively and actively managed strategies and in value and growth styles, and by periodic rebalancing of asset classes, strategies and investment styles to objectively set targets.

The following target allocation and ranges have been set for each asset class:

Asset Class	Target Allocation		Target Range
U.S. equities	8	%	0-16	%
Non-U.S. equities	8	%	0-16	%
Fixed income/cash	56	%	24-72	%
Alternative investments	8	%	0-28	%
Absolute return strategies	20	%	10-30	%

Ranges recognize the tendency of trends to persist and are designed to minimize transaction costs associated with rebalancing. Asset class target allocations are reviewed periodically and adjusted as appropriate. In September 2006, we made a voluntary pension plan contribution of $80.0 million and in May 2007, we made an additional $100.0 million voluntary contribution to our defined benefit pension plan. As a result of these voluntary contributions and favorable asset performance during 2006 and 2007, the asset allocation in our pension plan was adjusted to insulate the plan from discount rate risk and to reduce the plan’s exposure to equity investments.

For our domestic qualified pension plans, based on current funding requirements, we will not be required to make any cash contributions at least through 2010. We do have a small Canadian defined benefit pension plan to which we made $4.5 million of contributions in 2009 and we anticipate approximately $4 million of contributions in 2010.

Determining which hierarchical level an asset or liability falls within requires significant judgment. The following table summarizes our defined benefit pension plan assets measured at fair value as of December 31, 2009:

U.S. equities—This class included actively and passively managed common equity securities comprised primarily of large-capitalization stocks with value, core and growth strategies.

Non-U.S. equities—This class included actively managed common equity securities comprised primarily of international large-capitalization stocks from both developed and emerging markets.

Fixed income and cash—This class included debt instruments issued by the US and Canadian Treasury, U.S. Agencies, corporate debt instruments, asset- and mortgage-backed securities and cash.

Event driven hedge funds—This class included hedge funds that invest in securities to capture excess returns that are driven by market or specific company events including activist investment philosophies and the arbitrage of equity and private and public debt securities.

Market neutral hedge funds—This class included investments in U.S. and international equities and fixed income securities while maintaining a market neutral position in those markets.

Real estate funds—This class included several funds that invest primarily in U.S. commercial real estate.

Private equity funds—This class included several private equity funds that invest primarily in infrastructure and U.S. power generation and transmission assets.

Other hedge funds—This class primarily included uninvested cash, long-short equity strategies and a global macro fund which invested in fixed income, equity, currency, commodity and related derivative markets.

Absolute return strategies—This class included multiple strategies which use asset allocations that seek to provide a targeted rate of return over inflation. The investment managers allocate funds within asset classes that they consider to be undervalued in an effort to preserve gains in overvalued asset classes and to find opportunities in undervalued asset classes. At December 31, 2009, the asset allocation included investment in approximately 30% equities, 60% cash and fixed income, and 10% alternative investments.

U.S. equities and non-U.S. equities are primarily valued based on the closing price reported in an active market on which the individual securities are traded. Fixed income investments are primarily valued at the closing price reported, if traded on an active market, values derived from comparable securities of issuers with similar credit ratings, or under a discounted cash flow approach that utilizes observable inputs, such as current yields of similar instruments, but includes adjustments for risks that may not be observable such as certain credit and liquidity risks. Alternative investments are primarily valued at the net asset value as determined by the independent administrator or custodian of the fund. The net asset value is based on the underlying investments, which are valued using inputs such as quoted market prices of identical instruments, discounted future cash flows, independent appraisals, and market-based comparable data. Absolute return strategies are commingled funds which reflect the fair value of our ownership interest in these funds. The investments in these commingled funds include some or all of the above asset classes and are primarily valued at net asset values based on the underlying investments, which are valued consistent with the methodologies described above for each asset class.

The following table summarizes the activity for our defined benefit pension plan level 3 assets for the year ended December 31, 2009:

POSTRETIREMENT BENEFITS

We provide certain postretirement health care (medical) and life insurance benefits for eligible active and retired domestic employees. The health care plans are contributory with participants’ contributions adjusted annually based on medical rates of inflation and plan experience. We use a measurement date of December 31 for our postretirement plans.

Under ASC 715, formerly SFAS No. 158, we recorded a $4.3 million after-tax charge ($6.7 million pretax) to shareholders’ equity as of December 31, 2009 for our other postretirement plans. In 2008, we recorded a $3.8 million after-tax credit ($6.2 million pretax) to shareholders’ equity as of December 31, 2008 for our other postretirement plans.

The service cost and amortization of prior service cost components of postretirement benefit expense related to the employees of the operating segments are allocated to the operating segments based on their respective estimated census data. Therefore, the portion of other postretirement benefit costs for the Metals business employees of $4.4 million for the period of our ownership in 2007 was included in income from discontinued operations.

In 2007, we recorded an other postretirement benefits curtailment credit of $1.1 million related to the sale of the Metals business, which was included in the loss on disposal of discontinued operations.

Other Postretirement Benefits Plan Assumptions

Certain actuarial assumptions, such as discount rate, have a significant effect on the amounts reported for net periodic benefit cost and accrued benefit obligation amounts.

	Other Postretirement Benefits
Weighted Average Assumptions:	2009			2008			2007
Discount rate—periodic benefit cost		6.25	%		6.25	%		6.0	%
Discount rate—benefit obligation		5.25	%		6.25	%		6.25	%

We review external data and our own internal trends for healthcare costs to determine the healthcare cost for the post retirement benefit obligation. The assumed healthcare cost trend rates for pre-65 retirees were as follows:

	Other Postretirement Benefits
	2009			2008
Healthcare cost trend rate assumed for next year		9.5	%		9.0	%
Rate that the cost trend rate gradually declines to		5.0	%		5.0	%
Year that the rate reaches the ultimate rate	2019			2014

For post-65 retirees, we provide a fixed dollar benefit, which is not subject to escalation.

Assumed healthcare cost trend rates have an effect on the amounts reported for the healthcare plans. A one-percentage-point change in assumed healthcare cost trend rates would have the following effects:

	One-Percentage Point Increase		One-Percentage Point Decrease
	($ in millions)
Effect on total of service and interest costs	$	0.3	$	(0.2	)
Effect on postretirement benefit obligation		3.9		(4.9	)

We expect to make payments of approximately $8 million in 2010 and $7 million for each of the next four years under the provisions of our other postretirement benefit plans.

Realization of the net deferred tax assets is dependent on future reversals of existing temporary differences and adequate future taxable income, exclusive of reversing temporary differences and carryforwards. Although realization is not assured, we believe that it is more likely than not that the net deferred tax assets will be realized.

At December 31, 2009, refundable income taxes of $19.4 million were included in other current assets in the consolidated balance sheet.

At December 31, 2009 and 2008, we had federal tax benefits of $3.8 million and $8.5 million, respectively, relating to actual foreign tax credit carryforwards. At December 31, 2009 and 2008, we had a valuation allowance of $3.8 million and $3.5 million, respectively, due to uncertainties regarding the realization of the tax benefits of our actual foreign tax credit carryforwards. Our tax benefits for the foreign tax credit carryforwards and the associated valuation allowance were as follows:

	Foreign Tax Benefit			Valuation Allowance

In 2007, we acquired federal tax benefits of $4.8 million as part of the Pioneer acquisition associated with the expected future foreign tax credits that will be generated by the deferred tax liabilities of Pioneer’s Canadian subsidiary. At December 31, 2009, we had federal tax benefits of $3.5 million recorded associated with the expected future foreign tax credits. Realization of the tax benefits associated with such foreign tax credits is dependent upon reversal of Canadian temporary differences, future U.S. taxable income and future foreign source taxable income. We believe that it is more likely than not that the deferred tax benefits will be realized and no valuation allowance is necessary.

We acquired a U.S. net operating loss carryforward (NOL) of approximately $6.6 million (representing $2.3 million of deferred tax assets) as part of the Pioneer acquisition. At December 31, 2009, we had approximately $5.1 million (representing $1.8 million of deferred tax assets) remaining, that will expire in years 2017 through 2020, if not utilized. The utilization of this NOL is limited under Section 382 of the Internal Revenue Code to $0.5 million in each year through 2020. We believe that it is more likely than not that the NOL will be realized and no valuation allowance is necessary.

At December 31, 2009, we had deferred state tax benefits of $1.5 million relating to state NOLs, which are available to offset future state taxable income through 2023. Due to uncertainties regarding realization of the tax benefits, a valuation allowance of $0.8 million has been applied against the deferred state tax benefits at December 31, 2009.

At December 31, 2009, we had deferred state tax benefits of $7.5 million relating to state tax credits that are available to offset future state tax liabilities. Due to uncertainties regarding the realization of these state tax credits, a valuation allowance of $7.1 million has been applied against the deferred state tax credits at December 31, 2009.

At December 31, 2009, we had a capital loss carryforward of $43.2 million (representing $16.6 million of deferred tax assets) that is available to offset future consolidated capital gains. Due to uncertainties regarding the realization of the capital loss carryforward, a valuation allowance of $16.6 million has been applied against the deferred tax benefit at December 31, 2009.

The total amount of undistributed earnings of foreign subsidiaries was approximately $33.3 million at December 31, 2009. The Company has not provided deferred taxes on foreign earnings because such earnings are indefinitely reinvested outside the United States. Deferred taxes have not been provided on the excess book basis in the shares of certain foreign subsidiaries because these basis differences are not expected to reverse in the foreseeable future. The undistributed earnings and excess book basis differences could reverse through a sale, receipt of dividends from the subsidiaries, as well as various other events. It is not practical to calculate the residual income tax that would result if these basis differences reversed due to the complexities of the tax law and the hypothetical nature of the calculations.

The American Jobs Creation Act (AJCA), signed into law in October 2004, made a number of changes to the income tax laws which will affect us in future years. The most significant change for us was a new deduction for qualifying domestic production activity, which replaced the extraterritorial income exclusion. As a result of AJCA, we expect a modest decline in our effective tax rate in 2010 and future years when the qualifying domestic production activity deduction increases.

In July 2006, the FASB issued Interpretation No. 48, “Accounting for Uncertainty in Income Taxes,” (FIN No. 48), which was incorporated into ASC 740 “Income Taxes” (ASC 740). This interpretation clarified the accounting for uncertainty in income taxes recognized in the financial statements in accordance with FASB No. 109. FIN No. 48 prescribed a recognition threshold and required a measurement of a tax position taken or expected to be taken in a tax return. This interpretation also provided guidance on the treatment of derecognition, classification, interest and penalties, accounting in interim periods, and disclosure. We adopted the provisions of FIN No. 48 on January 1, 2007. As a result of the implementation, we recognized a $0.1 million increase in the liability for unrecognized tax benefits, which was accounted for as an increase to Accumulated Deficit. In addition, FIN No. 48 required a reclassification of unrecognized tax benefits and related interest and penalties from deferred income taxes to current and long-term liabilities. At January 1, 2007, we reclassified $19.8 million from Deferred Income Taxes to Accrued Liabilities ($3.1 million) and Other Liabilities ($16.7 million).

We acquired $29.8 million of gross unrecognized tax benefits in conjunction with the Pioneer acquisition, all of which would have been a reduction to goodwill, if recognized prior to 2009. During third quarter 2008, we favorably resolved $7.6 million of Pioneer unrecognized tax benefits associated with certain audits, which was recorded as a reduction to goodwill. After adopting ASC 805, formerly SFAS No. 141R in 2009, any remaining balance of unrecognized tax benefits will affect our effective tax rate instead of goodwill, if recognized. If these tax benefits are not realized, the result, as of December 31, 2009, would be cash tax payments of $11.4 million.

As of December 31, 2009, we had $50.8 million of gross unrecognized tax benefits (including Pioneer), of which $48.3 million would impact the effective tax rate, if recognized. If these tax benefits are not recognized, the result would be cash tax payments of $31.8 million. As of December 31, 2008, we had $50.2 million of gross unrecognized tax benefits (including Pioneer), all of which would have impacted the effective rate, if recognized. The change for 2009 relates to additional gross unrecognized benefits for ongoing income tax audits by various taxing jurisdictions and current year tax positions, as well as the expiration of the statute of limitations in domestic jurisdictions and settlements of ongoing audits. In 2009, the decrease for prior year tax positions included $0.4 million of foreign currency translation. The amounts of unrecognized tax benefits were as follows:

	December 31,
	2009			2008
	($ in millions)
Beginning balance	$	50.2		$	51.8
Increase for prior year tax positions		4.7			2.2
Decrease for prior year tax positions		(1.8	)		(2.3	)
Acquired from Pioneer		―			(7.4	)
Increase for current year tax positions		0.8			7.4
Decrease due to tax settlements		(0.4	)		(0.4	)
Reductions due to statute of limitations		(2.7	)		(1.1	)
Ending balance	$	50.8		$	50.2

In 2006, the IRS commenced an examination of our U.S. income tax return for 2004. In June 2007, we reached an agreement in principle with the IRS for the 2004 tax examination. The settlement resulted in a reduction of income tax expense of $0.6 million in 2007 related primarily to a favorable adjustment to our extraterritorial income exclusion. In connection with the settlement, we paid $3.2 million to the IRS in June 2007.

We recognize interest and penalty expense related to unrecognized tax positions as a component of the income tax provision. As of December 31, 2009, interest and penalties accrued was $3.8 million. For 2009, 2008 and 2007, we expensed interest and penalties of $1.1 million, $1.5 million, and $1.4 million, respectively.

As of December 31, 2009, we believe it is reasonably possible that our total amount of unrecognized tax benefits will decrease by approximately $10.5 million over the next twelve months. The reduction primarily relates to settlements with tax authorities and the lapse of federal, state, and foreign statutes of limitation.

Our federal and Canadian income tax returns for 2006 to 2008 are open tax years under statute of limitations. We file in numerous states, Canadian provinces, and foreign jurisdictions with varying statutes of limitation open from 2004 through 2008 depending on each jurisdiction’s unique statute of limitation. The IRS has commenced an audit of our U.S. income tax return for 2006. We believe we have adequately provided for all tax positions; however, amounts asserted by taxing authorities could be greater than our accrued position.

Pioneer filed income tax returns in the U.S., various states, Canada, and various Canadian provinces. Pioneer income tax returns are open for examination for the years 2005 and forward. The IRS commenced an audit of Pioneer’s 2006 and 2007 tax years in the fourth quarter of 2008. The IRS audit of Pioneer’s 2006 and 2007 tax years was closed in the fourth quarter of 2009 and resulted in no change to taxable income as originally reported. The Canada Revenue Agency has commenced an audit of Pioneer’s Canadian tax returns for its 2005 to 2007 tax years. No issues have arisen to date that would suggest an additional tax liability should be recognized.

CONTRIBUTING EMPLOYEE OWNERSHIP PLAN

The CEOP is a defined contribution plan available to essentially all domestic employees. Company matching contributions are invested in the same investment allocation as the employee’s contribution. The matching contributions for salaried employees were contingent upon our financial performance through 2007. Beginning in 2008, the matching contributions for salaried employees were no longer contingent upon financial performance. During 2007, a performance match was earned. Our matching contributions for eligible employees amounted to $5.0 million, $4.6 million, and $7.7 million in 2009, 2008 and 2007, respectively. Effective January 1, 2010, we suspended the match on all salaried and certain non-bargained hourly employees’ contributions.

Employees become vested in the value of the contributions we make to the CEOP according to a schedule based on service. After two years of service, participants are 25% vested. They vest in increments of 25% for each additional year and after five years of service, they are 100% vested in the value of the contributions that we have made to their accounts.

Employees may transfer any or all of the value of the investments, including Olin common stock, to any one or combination of investments available in the CEOP. Employees may transfer balances daily and may elect to transfer any percentage of the balance in the fund from which the transfer is made. However, when transferring out of a fund, employees are prohibited from trading out of the fund to which the transfer was made for seven calendar days. This limitation does not apply to trades into the money market fund or the Olin Common Stock Fund.

STOCK-BASED COMPENSATION

Stock-based compensation expense was allocated to the operating segments for the portion related to employees whose compensation would be included in cost of goods sold with the remainder recognized in corporate/other. There were no significant capitalized stock-based compensation costs. Total stock-based compensation expense was $9.4 million for 2009 and 2008, and $7.1 million for 2007.

Stock Plans

Under the stock option and long-term incentive plans, options may be granted to purchase shares of our common stock at an exercise price not less than fair market value at the date of grant, and are exercisable for a period not exceeding ten years from that date. Stock options, restricted stock and performance shares typically vest over three years. We issue shares to settle stock options, restricted stock, and share-based performance awards. On April 23, 2009, the shareholders approved the 2009 Long Term Incentive Plan which authorized an additional 3.0 million shares available for grant. In 2009, long-term incentive awards included stock options, performance share awards, and restricted stock. The stock option exercise price was set at the fair market value of common stock on the date of the grant, and the options have a ten-year term.

In 2000, a one-time grant of Performance Accelerated Vesting Stock Options was granted with an exercise price of $18.97, which was the fair market value of our common stock on the date of grant. These options had a term of 120 months and would vest in 119 months, and could vest early, but only if the stock price increased to $28 per share or more for 10 days in any 30 day calendar period. During 2008, the criteria for early vesting was met; therefore, all of the outstanding Performance Accelerated Vesting Stock Options are vested. Performance Accelerated Vesting Stock Options of 295,000 shares were outstanding at December 31, 2009.

Stock option transactions were as follows:

At December 31, 2009, the average exercise period for all outstanding and exercisable options was 65 months and 45 months, respectively. At December 31, 2009, the aggregate intrinsic value (the difference between the exercise price and market value) for outstanding options was $4.2 million and exercisable options was $1.1 million. The total intrinsic value of options exercised during the years ended December 31, 2009 and 2008 was zero and $15.9 million, respectively.

The total unrecognized compensation cost related to unvested stock options at December 31, 2009 was $3.1 million and was expected to be recognized over a weighted average period of 1.2 years.

The following table provides certain information with respect to stock options exercisable at December 31, 2009:

(1)	All available to be issued as stock options, but includes a sub-limit for all types of stock awards of 2,590,294 shares.

Under the stock purchase plans, our non-employee directors may defer certain elements of their compensation into shares of our common stock based on fair market value of the shares at the time of deferral. Non-employee directors annually receive stock grants as a portion of their director compensation. Of the shares reserved under the stock purchase plans at December 31, 2009, 254,244 shares were committed.

Performance share awards are denominated in shares of our stock and are paid half in cash and half in stock. Payouts are based on Olin’s average annual return on capital over a three-year performance cycle in relation to the average annual return on capital over the same period among a portfolio of public companies which are selected in concert with outside compensation consultants. The expense associated with performance shares is recorded based on our estimate of our performance relative to the respective target. If an employee leaves the company before the end of the performance cycle, the performance shares may be prorated based on the number of months of the performance cycle worked and are settled in cash instead of half in cash and half in stock when the three-year performance cycle is completed. Performance share transactions were as follows:

At December 31, 2009, the liability recorded for performance shares to be settled in cash totaled $4.4 million. The total unrecognized compensation cost related to unvested performance shares at December 31, 2009 was $4.0 million and was expected to be recognized over a weighted average period of 1.1 years.

SHAREHOLDERS’ EQUITY

During 2009 and 2008, we issued 1,260,693 shares and 947,643 shares of common stock, respectively, with a total value of $16.9 million and $18.1 million, respectively, to the CEOP. These shares were issued to satisfy the investment in our common stock resulting from employee contributions, our matching contributions, retirement contributions and re-invested dividends.

There were no share repurchases in 2009, 2008 and 2007. Under programs previously approved by our board of directors, 154,076 shares remained to be repurchased as of December 31, 2009.

The following table represents the activity included in accumulated other comprehensive loss:

Pension and postretirement benefits (net of taxes) activity in other comprehensive loss included the amortization of prior service costs and actuarial losses and pension and postretirement liability adjustments.

As a result of the sale of the Metals business in 2007, we recognized an after-tax loss on previously unrecognized foreign currency translation adjustments and net unrecognized losses on derivative contracts of $4.4 million and $3.6 million, respectively, which were included in the loss on disposal of discontinued operations.

Unrealized gains and losses on derivative contracts (net of taxes) activity in other comprehensive loss included a deferred tax provision (benefit) for 2009, 2008 and 2007 of $23.2 million, $(16.6) million and $2.0 million, respectively. Pension and postretirement benefits (net of taxes) activity in other comprehensive loss included a deferred tax provision (benefit) for 2009, 2008 and 2007 of $(9.7) million, $(56.3) million and $105.4 million, respectively.

SEGMENT INFORMATION

We define segment results as income (loss) from continuing operations before interest expense, interest income, other income (expense), and income taxes, and include the results of non-consolidated affiliates. Consistent with the guidance in ASC 280, formerly SFAS No. 131, we have determined it is appropriate to include the operating results of non-consolidated affiliates in the relevant segment financial results. Our management considers SunBelt to be an integral component of the Chlor Alkali Products segment. It is engaged in the same business activity as the segment, including joint or overlapping marketing, management, and manufacturing functions.

ENVIRONMENTAL

In the United States, the establishment and implementation of federal, state and local standards to regulate air, water and land quality affect substantially all of our manufacturing locations. Federal legislation providing for regulation of the manufacture, transportation, use and disposal of hazardous and toxic substances, and remediation of contaminated sites, has imposed additional regulatory requirements on industry, particularly the chemicals industry. In addition, implementation of environmental laws, such as the Resource Conservation and Recovery Act and the Clean Air Act, has required and will continue to require new capital expenditures and will increase plant operating costs. Our Canadian facility is governed by federal environmental laws administered by Environment Canada and by provincial environmental laws enforced by administrative agencies. Many of these laws are comparable to the U.S. laws described above. We employ waste minimization and pollution prevention programs at our manufacturing sites.

We are party to various governmental and private environmental actions associated with past manufacturing facilities and former waste disposal sites. Associated costs of investigatory and remedial activities are provided for in accordance with generally accepted accounting principles governing probability and the ability to reasonably estimate future costs. Our ability to estimate future costs depends on whether our investigatory and remedial activities are in preliminary or advanced stages. With respect to unasserted claims, we accrue liabilities for costs that, in our experience, we may incur to protect our interests against those unasserted claims. Our accrued liabilities for unasserted claims amounted to $3.4 million at December 31, 2009. With respect to asserted claims, we accrue liabilities based on remedial investigation, feasibility study, remedial action and OM&M expenses that, in our experience, we may incur in connection with the asserted claims. Required site OM&M expenses are estimated and accrued in their entirety for required periods not exceeding 30 years, which reasonably approximates the typical duration of long-term site OM&M.

Our liabilities for future environmental expenditures were as follows:

	December 31,
	2009			2008
	($ in millions)
Beginning balance	$	158.9		$	155.6
Charges to income		24.1			27.7

Pioneer acquired liabilities		―			2.1
Currency translation adjustments		2.1			(2.8	)
Ending balance	$	166.1		$	158.9

At December 31, 2009 and 2008, our consolidated balance sheets included environmental liabilities of $131.1 million and $123.9 million, respectively, which were classified as other noncurrent liabilities. Our environmental liability amounts did not take into account any discounting of future expenditures or any consideration of insurance recoveries or advances in technology. These liabilities are reassessed periodically to determine if environmental circumstances have changed and/or remediation efforts and our estimate of related costs have changed. As a result of these reassessments, future charges to income may be made for additional liabilities. Of the $166.1 million included on our consolidated balance sheet at December 31, 2009 for future environmental expenditures, we currently expect to utilize $98.7 million of the reserve for future environmental expenditures over the next 5 years, $20.2 million for expenditures 6 to 10 years in the future, and $47.2 million for expenditures beyond 10 years in the future.

Our total estimated environmental liability at December 31, 2009, was attributable to 68 sites, 16 of which were USEPA NPL sites. Ten sites accounted for 79% of our environmental liability and, of the remaining 58 sites, no one site accounted for more than 2% of our environmental liability. At one of these ten sites a remedial action plan is being implemented. At five of the ten sites, part of the site is subject to a remedial investigation and another part is in the long-term OM&M stage. At one of these ten sites, part of the site is subject to a remedial investigation, part to a remedial action plan, and another part is in the long-term OM&M stage. At two sites, part of the site is subject to a remedial action plan and part of the site to long-term OM&M. The one remaining site is in long-term OM&M. All ten sites are either associated with past manufacturing operations or former waste disposal sites. None of the ten largest sites represents more than 20% of the liabilities reserved on our consolidated balance sheet at December 31, 2009 for future environmental expenditures.

Charges or credits to income for investigatory and remedial efforts were material to operating results in 2009, 2008 and 2007 and may be material to operating results in future years.

Environmental provisions (credited) charged to income, which are included in cost of goods sold, were as follows:

	Years ended December 31,
	2009			2008		2007
	($ in millions)
Charges to income	$	24.1		$	27.7	$	37.9
Recoveries from third parties of costs incurred and expensed in prior periods		(82.1	)		―		―
Total environmental (income) expense	$	(58.0	)	$	27.7	$	37.9

These charges relate primarily to remedial and investigatory activities associated with past manufacturing operations and former waste disposal sites.

Annual environmental-related cash outlays for site investigation and remediation are expected to range between approximately $20 million to $40 million over the next several years, which are expected to be charged against reserves recorded on our balance sheet. While we do not anticipate a material increase in the projected annual level of our environmental-related cash outlays, there is always the possibility that such an increase may occur in the future in view of the uncertainties associated with environmental exposures. Environmental exposures are difficult to assess for numerous reasons, including the identification of new sites, developments at sites resulting from investigatory studies, advances in technology, changes in environmental laws and regulations and their application, changes in regulatory authorities, the scarcity of reliable data pertaining to identified sites, the difficulty in assessing the involvement and financial capability of other PRPs and our ability to obtain contributions from other parties and the lengthy time periods over which site remediation occurs. It is possible that some of these matters (the outcomes of which are subject to various uncertainties) may be resolved unfavorably to us, which could materially adversely affect our financial position or results of operations. At December 31, 2009, we estimate we may have additional contingent environmental liabilities of $50 million in addition to the amounts for which we have already recorded as a reserve.

COMMITMENTS AND CONTINGENCIES

The following table summarizes our contractual commitments under non-cancelable operating leases and purchase contracts as of December 31, 2009:

	Operating Leases		Purchase Commitments
	($ in millions)
2010	$	37.0	$	48.6
2011		33.3		7.9
2012		29.1		4.6

2014		20.0		3.4
Thereafter		65.8		12.0
Total commitments	$	210.7	$	80.3

We lease certain properties, such as railroad cars; distribution, warehousing and office space; and data processing and office equipment. Virtually none of our lease agreements contain escalation clauses or step rent provisions. Total rent expense charged to operations amounted to $45.4 million, $46.2 million, and $33.3 million in 2009, 2008 and 2007, respectively (sublease income is not significant). The above purchase commitments include raw material and utility purchasing commitments utilized in our normal course of business for our projected needs.

In conjunction with the St. Gabriel conversion and expansion project, we entered into a twenty-year brine and pipeline supply agreement with PetroLogistics. PetroLogistics installed, owns and operates, at its own expense, a pipeline supplying brine to the St. Gabriel, LA facility. Beginning November 2009, we are obligated to make a fixed annual payment over the life of the contract of $2.0 million for use of the pipeline, regardless of the amount of brine purchased. We also have a minimum usage requirement for brine of $8.4 million over the first five-year period of the contract. After the first-five year period, the contract contains a buy out provision exercisable by us for $12.0 million.

On December 31, 1997, we entered into a long-term, sulfur dioxide supply agreement with Alliance, formerly known as RFC SO2, Inc. Alliance has the obligation to deliver annually 36,000 tons of sulfur dioxide. Alliance owns the sulfur dioxide plant, which is located at our Charleston, TN facility and is operated by us. The price for the sulfur dioxide is fixed over the life of the contract, and under the terms of the contract, we are obligated to make a monthly payment of $0.2 million regardless of the sulfur dioxide purchased. Commitments related to this agreement are $2.4 million per year for 2010 and 2011 and $0.6 million in 2012. This supply agreement expires in 2012.

100

We, and our subsidiaries, are defendants in various legal actions (including proceedings based on alleged exposures to asbestos) incidental to our past and current business activities. While we believe that none of these legal actions will materially adversely affect our financial position, in light of the inherent uncertainties of litigation, we cannot at this time determine whether the financial impact, if any, of these matters will be material to our results of operations.

During the ordinary course of our business, contingencies arise resulting from an existing condition, situation, or set of circumstances involving an uncertainty as to the realization of a possible gain contingency. In certain instances such as environmental projects, we are responsible for managing the cleanup and remediation of an environmental site. There exists the possibility of recovering a portion of these costs from other parties. We account for gain contingencies in accordance with the provisions of ASC 450, formerly SFAS No. 5, and therefore do not record gain contingencies and recognize income until it is earned and realizable.

DERIVATIVE FINANCIAL INSTRUMENTS

We are exposed to market risk in the normal course of our business operations due to our purchases of certain commodities, our ongoing investing and financing activities, and our operations that use foreign currencies. The risk of loss can be assessed from the perspective of adverse changes in fair values, cash flows and future earnings. We have established policies and procedures governing our management of market risks and the use of financial instruments to manage exposure to such risks. ASC 815, formerly SFAS No. 133, required an entity to recognize all derivatives as either assets or liabilities in the statement of financial position and measure those instruments at fair value. We use hedge accounting treatment for substantially all of our business transactions whose risks are covered using derivative instruments. In accordance with ASC 815, we designate commodity forward contracts as cash flow hedges of forecasted purchases of commodities and certain interest rate swaps as fair value hedges of fixed-rate borrowings. We do not enter into any derivative instruments for trading or speculative purposes.

Energy costs, including electricity used in our Chlor Alkali Products segment, and certain raw materials and energy costs, namely copper, lead, zinc, electricity, and natural gas used primarily in our Winchester segment, are subject to price volatility. Depending on market conditions, we may enter into futures contracts and put and call option contracts in order to reduce the impact of commodity price fluctuations. The majority of our commodity derivatives expire within one year. Those commodity contracts that extend beyond one year correspond with raw material purchases for long-term fixed-price sales contracts.

We enter into forward sales and purchase contracts to manage currency risk resulting from purchase and sale commitments denominated in foreign currencies (principally Canadian dollar and Euro). All of the currency derivatives expire within two years and are for United States dollar equivalents. Our foreign currency forward contracts do not meet the criteria to qualify for hedge accounting. At December 31, 2009 and December 31, 2008, we had forward contracts to sell foreign currencies with a notional value of $0.3 million and zero, respectively. At December 31, 2009 and December 31, 2008, we had forward contracts to buy foreign currencies with a notional value of $1.7 million and zero, respectively.

In 2001 and 2002, we entered into interest rate swaps on $75 million of our underlying fixed-rate debt obligations, whereby we agreed to pay variable rates to a counterparty who, in turn, pays us fixed rates. The counterparty to these agreements is Citibank, N.A., a major financial institution. In January 2009, we entered into a $75 million fixed interest rate swap with equal and opposite terms as the $75 million variable interest rate swaps on the 2011 Notes. We have agreed to pay a fixed rate to a counterparty who, in turn, pays us variable rates. The counterparty to this agreement is Bank of America, a major financial institution. The result was a gain of $7.9 million on the $75 million variable interest rate swaps, which will be recognized through 2011. In January 2009, we de-designated our $75 million interest rate swaps that had previously been designated as fair value hedges. The $75 million variable interest rate swaps and the $75 million fixed interest rate swap do not meet the criteria for hedge accounting. All changes in the fair value of these interest rate swaps are recorded currently in earnings.

101

Cash Flow Hedges

ASC 815 requires that all derivative instruments be recorded on the balance sheet at their fair value. For derivative instruments that are designated and qualify as a cash flow hedge, the change in fair value of the derivative is recognized as a component of other comprehensive loss until the hedged item is recognized into earnings. Gains and losses on the derivatives representing hedge ineffectiveness are recognized currently in earnings.

We had the following notional amount of outstanding commodity forward contracts that were entered into to hedge forecasted purchases:

	December 31,
	2009		2008
	($ in millions)
Copper	$	34.1	$	49.8
Zinc		3.2		5.4
Lead		17.0		26.8
Natural gas		7.1		2.0

As of December 31, 2009, the counterparty to $36.2 million of these commodity forward contracts was Wells Fargo, a major financial institution.

If commodity prices were to remain at the levels they were at December 31, 2009, approximately $12.5 million of deferred gains would be reclassified into earnings during the next twelve months. The actual effect on earnings will be dependent on actual commodity prices when the forecasted transactions occur.

Fair Value Hedges

For derivative instruments that are designated and qualify as a fair value hedge, 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 earnings. We include the gain or loss on the hedged items (fixed-rate borrowings) in the same line item, interest expense, as the offsetting loss or gain on the related interest rate swaps. As of December 31, 2009 and December 31, 2008, the total notional amount of our interest rate swaps designated as fair value hedges were $26.6 million and $101.6 million, respectively. In January 2009, we de-designated our $75 million interest rate swaps that had previously been designated as fair value hedges.

We use interest rate swaps as a means of managing interest expense and floating interest rate exposure to optimal levels. These interest rate swaps are treated as fair value hedges. The accounting for gains and losses associated with changes in fair value of the derivative and the effect on the consolidated financial statements will depend on the hedge designation and whether the hedge is effective in offsetting changes in fair value of cash flows of the asset or liability being hedged. We have entered into $26.6 million of such swaps, whereby we agreed to pay variable rates to a counterparty who, in turn, pays us fixed rates. The counterparty to these agreements is Citibank, N.A., a major financial institution. In all cases, the underlying index for the variable rates is six-month LIBOR. Accordingly, payments are settled every six months and the terms of the swaps are the same as the underlying debt instruments.

102

Financial Statement Impacts

We present our derivative assets and liabilities in our consolidated balance sheets on a net basis. We net derivative assets and liabilities whenever we have a legally enforceable master netting agreement with the counterparty to our derivative contracts. We use these agreements to manage and substantially reduce our potential counterparty credit risk.

The following table summarizes the location and fair value of the derivative instruments on our consolidated balance sheets. The table disaggregates our net derivative assets and liabilities into gross components on a contract-by-contract basis before giving effect to master netting arrangements:

Credit Risk and Collateral

By using derivative instruments, we are exposed to credit and market risk. If a counterparty fails to fulfill its performance obligations under a derivative contract, our credit risk will equal the fair-value gain in a derivative. Generally, when the fair value of a derivative contract is positive, this indicates that the counterparty owes us, thus creating a repayment risk for us. When the fair value of a derivative contract is negative, we owe the counterparty and, therefore, assume no repayment risk. We minimize the credit (or repayment) risk in derivative instruments by entering into transactions with high-quality counterparties. We monitor our positions and the credit ratings of our counterparties and we do not anticipate non-performance by the counterparties.

Based on the agreements with our various counterparties, cash collateral is required to be provided when the net fair value of the derivatives, with the counterparty, exceed a specific threshold. If the threshold is exceeded, cash is either provided by the counterparty to us if the value of the derivatives is our asset, or cash is provided by us to the counterparty if the value of the derivatives is our liability. As of December 31, 2009, the amounts recognized in other current assets for cash collateral provided by counterparties was $2.2 million. As of December 31, 2008, the amounts recognized in accrued liabilities for the right to reclaim cash collateral totaled $22.0 million. In all instances where we are party to a master netting agreement, we offset the receivable or payable recognized upon payment of cash collateral against the fair value amounts recognized for derivative instruments that have also been offset under such master netting agreements. A reclassification totaling $22.0 million from other current assets to accrued liabilities was made conforming cash collateral to the classification of the related derivative instruments at December 31, 2008.

104

FAIR VALUE MEASUREMENTS

Assets and liabilities recorded at fair value in the consolidated balance sheets are categorized based upon the level of judgment associated with the inputs used to measure their fair value. Hierarchical levels are directly related to the amount of subjectivity associated with the inputs to fair valuation of these assets and liabilities. We are required to separately disclose assets and liabilities measured at fair value on a recurring basis, from those measured at fair value on a nonrecurring basis. Nonfinancial assets measured at fair value on a nonrecurring basis are intangible assets and goodwill, which are reviewed annually in the fourth quarter and/or when circumstances or other events indicate that impairment may have occurred. Determining which hierarchical level an asset or liability falls within requires significant judgment. The following table summarizes the financial instruments measured at fair value in the consolidated balance sheets:

Balance at December 31, 2009	Quoted Prices in Active Markets for Identical Assets (Level 1)			Significant Other Observable Inputs (Level 2)			Significant Unobservable Inputs (Level 3)			Total

Short-Term Investments

We classified our marketable securities as available-for-sale which were reported at fair market value. Unrealized gains and losses, to the extent such losses are considered temporary in nature, are included in accumulated other comprehensive loss, net of applicable taxes. At such time as the decline in fair market value and the related unrealized loss is determined to be a result of impairment of the underlying instrument, the loss is recorded as a charge to earnings. Fair values for marketable securities are based upon prices and other relevant information observable in market transactions involving identical or comparable assets or liabilities or prices obtained from independent third-party pricing services. The third-party pricing services employ various models that take into consideration such market-based factors as recent sales, risk-free yield curves, prices of similarly rated bonds, and direct discussions with dealers familiar with these types of securities.

105

As of June 30, 2008, we held corporate debt securities totaling $26.6 million of par value with a fair value of $20.5 million. In the second quarter of 2008, a temporary unrealized after-tax loss of $3.7 million ($6.1 million pretax) was recorded in accumulated other comprehensive loss. As of June 30, 2008, we concluded no other-than-temporary impairment losses had occurred. The AA-rated issuer of these debt securities had funded all redemptions at par and maintained short-term A1/P2 credit ratings. We entered into this structured investment vehicle in March 2006 as part of an approved cash management portfolio. Given our liquidity and capital structure, we had the ability to hold these debt securities until maturity on April 1, 2009.

Through September 30, 2008, the issuer of these debt securities had continued to fund all redemptions at par but was downgraded to short-term A3/P2 credit ratings. On October 1, 2008, the issuer of these debt securities announced it would cease trading and appoint a receiver as a result of financial market turmoil. The decline in the market value of the assets supporting these debt securities negatively impacted the liquidity of the issuer. On October 1, subsequent to the issuer’s announcement, the Moody’s rating for these debt securities was downgraded from A3 to Ca.

During the third quarter of 2008, we determined that these debt securities had no fair market value due to the actions taken by the issuer, turmoil in the financial markets, the lack of liquidity of the issuer, and the lack of trading in these debt securities. These factors led management to believe the recovery of the asset value, if any, was highly unlikely.

Because of the unlikelihood that these debt securities would recover in value, we recorded an after-tax impairment loss of $26.6 million in other income (expense) in the third quarter of 2008. We are currently unable to utilize the capital loss resulting from the impairment of these corporate debt securities; therefore, no tax benefit has been recognized for the impairment loss.

Interest Rate Swaps

The fair value of the interest rate swaps was included in other assets, long-term debt and other liabilities as of December 31, 2009 and 2008. These financial instruments were valued using the “income approach” valuation technique. This method used valuation techniques to convert future amounts to a single present amount. The measurement was based on the value indicated by current market expectations about those future amounts. We use interest rate swaps as a means of managing interest rates on our outstanding fixed-rate debt obligations.

Commodity Forward Contracts

The fair value of the commodity forward contracts was classified in other current assets as of December 31, 2009 and classified in accrued liabilities as of December 31, 2008, with unrealized gains and losses included in accumulated other comprehensive loss, net of applicable taxes. These financial instruments were valued primarily based on prices and other relevant information observable in market transactions involving identical or comparable assets or liabilities including both forward and spot prices for commodities. We use commodity forward contracts for certain raw materials and energy costs such as copper, zinc, lead, and natural gas to provide a measure of stability in managing our exposure to price fluctuations.

Foreign Currency Contracts

The fair value of the foreign currency contracts was classified in accrued liabilities as of December 31, 2009, with gains and losses included in selling and administration expense as these financial instruments do not meet the criteria to qualify for hedge accounting. These financial instruments were valued primarily based on prices and other relevant information observable in market transactions involving identical or comparable assets or liabilities including both forward and spot prices for foreign currencies. We enter into forward sales and purchase contracts to manage currency risk resulting from purchase and sale commitments denominated in foreign currencies (principally Canadian dollar and Euro).

Financial Instruments

The carrying values of cash and cash equivalents, accounts receivable and accounts payable approximated fair values due to the short-term maturities of these instruments. The fair value of our long-term debt was determined based on current market rates for debt of the same risk and maturities. At December 31, 2009 and December 31, 2008, the estimated fair value of debt was $416.0 million and $232.4 million, respectively, which compares to debt recorded on the balance sheet of $398.4 million and $252.4 million, respectively. The lower fair value of debt as of December 31, 2008 was due to the adverse conditions in the overall credit and financial markets experienced in 2008.

SunBelt Chlor Alkali Partnership

Notes to Financial Statements

December 31, 2009 and 2008

1. Organization

SunBelt Chlor Alkali Partnership (the Partnership) was formed on August 23, 1996, under a Partnership Agreement, between 1997 Chlor Alkali Venture, Inc. and Olin SunBelt Inc. (the Partners). 1997 Chlor Alkali Venture, Inc. is a wholly owned subsidiary of PolyOne Corporation (formerly The Geon Company) and Olin SunBelt Inc. is a wholly owned subsidiary of the Olin Corporation. Each of the Partners has a 50% interest in the Partnership. The Partnership Agreement provides that the capital investment of the Partners will be maintained and the Partnership’s income or loss will be allocated to the Partners based on their ownership interest percentages.

The Partnership was formed for the purpose of construction and operation of a Chlor-Alkali facility. The facility, which is located in McIntosh, Alabama produces chlorine, caustic soda and hydrogen.

2. Significant Accounting Policies

Cash and Cash Equivalent

The Partnership considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. There were no cash equivalents held by the Partnership as of December 31, 2009 and 2008.

Inventories

Inventories are valued at the lower of cost or market. Cost is determined by the first-in, first-out (FIFO) method.

Property, Plant and Equipment and Depreciation

Property, plant and equipment are carried at cost. Major renewals and betterments are capitalized. Maintenance and repair expenditures which do not improve or extend the life of the respective assets are expensed as incurred. Depreciation for all plant and equipment is computed using the straight-line method over their estimated useful lives. The ranges of estimated useful lives are as follows:

Land improvements	20 years
Buildings	20 years
Machinery and equipment	5–20 years

Long-lived assets are assessed for impairment when operating profits for the related business or a significant change in the use of an asset indicate that their carrying value may not be recoverable.

Notes to Financial Statements (continued)

2. Significant Accounting Policies (continued)

Deferred Financing Costs

Costs incurred by the Partnership in obtaining its long-term debt are deferred and amortized over the term of the debt using the effective interest method.

Financial Instruments

The carrying values of cash, accounts receivable and accounts payable approximate fair values due to the short-term maturities of these instruments. The fair value of our long-term debt was estimated based on current market rates for debt of similar risk and maturities. At December 31, 2009 and 2008, the estimated fair value of debt was approximately $97,300,000 and $84,500,000, which compares to debt recorded on the balance sheet of $97,500,000 and $109,687,500 at December 31, 2009 and 2008, respectively.

Revenue Recognition

The Partnership recognizes revenues upon passage of title which is based on shipping terms.

Shipping and Handling Costs

Shipping and handling costs are reflected in costs of sales.

Income Taxes

No provision is made for income taxes other than the Texas state gross margin tax as the Partnership’s results of operations are includable in the tax returns of the Partners. The Partnership paid taxes of $317,193 in 2009, $435,000 in 2008 and $0 in 2007.

2. Significant Accounting Policies (continued)

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the financial statements and the accompanying notes. Actual results could differ from those estimates.

Risks and Uncertainties

Since the Partnership’s major products are commodities, significant changes in the prices of chemical products could have a significant impact on the results of operations for any particular period. The Partnership had one major chlorine customer, OxyVinyls LP, during the periods presented, which accounted for 38%, 31%, and 38% of total sales for the years ended December 31, 2009, 2008 and 2007, respectively.

Subsequent Events

Events subsequent to December 31, 2009 have been evaluated through February 18, 2010, the date of issuance of these financial statements. There were no subsequent events requiring recognition in these financial statements for the year ended December 31, 2009.

3. Inventories

Inventories are comprised as follows:

	December 31,
	2009		2008

Finished goods	$	1,230,161	$	803,826

Less allowance for depreciation		155,410,376		140,045,309
	$	93,476,246	$	106,956,187

5. Transactions With Affiliates

The Partnership has various management service agreements, dated August 23, 1996, with the Olin Corporation. These agreements, which include compensation for managing the facility, an asset utilization fee, a fleet fee and a distribution fee, have terms from five to ten years with five year price adjustment renewals. Charges for these services were $8,412,847, $8,150,580, and $8,309,350 for 2009, 2008 and 2007, respectively, and are included in administrative and general expenses in the income statements.

The Partnership’s cash policy prohibits distributions to the Partners until the cash balance is sufficient to cover both the debt principal payments and interest expense for the year. The Partnership made distributions to the Partners totaling $68,820,581, $58,809,586 and $70,097,585 in 2009, 2008 and 2007, respectively.

In accordance with the Partnership Operating Agreement, the majority of chlorine produced by the Partnership is sold to OxyVinyls LP which was 24% owned by PolyOne Corporation until July 6, 2007.
