PART I

ITEM 1. BUSINESS

General

LSB Industries, Inc. (“LSB” or “Registrant”) was formed in 1968 as an Oklahoma corporation and became a Delaware corporation in 1977. LSB is a diversified holding company involved in manufacturing and marketing operations through its subsidiaries. LSB and its wholly-owned subsidiaries (the “Company”, “We”, “Us”, or “Our”) own the following core businesses:

| • |  | Chemical Business manufactures and sells nitrogen-based chemical products produced from four facilities located in El Dorado, Arkansas (the “El Dorado Facility”); Cherokee, Alabama (the “Cherokee Facility”); Pryor, Oklahoma (the “Pryor Facility”); and Baytown, Texas (the “Baytown Facility”) for the agricultural, industrial, and mining markets. Our products include high purity and commercial grade anhydrous ammonia for industrial and agricultural applications, industrial and fertilizer grade ammonium nitrate (“AN”), urea ammonium nitrate (“UAN”), sulfuric acids, nitric acids in various concentrations, nitrogen solutions, diesel exhaust fluid (“DEF”) and various other products.

| • |  | Climate Control Business manufactures and sells a broad range of heating, ventilation and air conditioning (“HVAC”) products in the niche markets we serve consisting of geothermal and water source heat pumps, hydronic fan coils, large custom air handlers, modular geothermal and other chillers and other related products used to control the environment in commercial/institutional and residential new building construction, renovation of existing buildings and replacement of existing systems. Our Climate Control Business manufactures and distributes its products from seven facilities located in Oklahoma City, Oklahoma.

Our Chemical Business is a supplier to some of the world’s leading chemical and industrial companies. By focusing on specific geographic areas, we have developed freight and distribution advantages over many of our competitors, and we believe our Chemical Business has established leading regional market positions.

We sell most of our industrial and mining products to customers pursuant to contracts containing minimum volumes and/or cost plus a profit provision. These contractual sales stabilize the effect of commodity cost changes and fluctuations in demand for these products due to the cyclicality of the end markets. Periodically we enter into forward sales commitments for agricultural products but we sell most of our agricultural products at the current spot market price in effect at time of shipment.

We believe our Climate Control Business has developed leadership positions in certain niche markets by offering extensive product lines, customized products and improved technologies. Under this focused strategy, we have developed what we believe to be the most extensive line of geothermal and water source heat pumps and hydronic fan coils in the United States (“U.S.”). Further, we believe that we were a pioneer in the use of geothermal technology in the climate control industry and we have used it to create what we believe to be the most energy efficient climate control systems commercially available today. We employ highly flexible production capabilities that allow us to custom design units for new construction as well as the retrofit and replacement markets. This flexibility positions us well for growth in commercial/institutional and residential construction markets.

In recent years, we have put heavy emphasis on our geothermal heating and air conditioning products, which are considered “green” technology and a form of renewable energy. We believe our geothermal systems are among the most energy efficient systems available in the market for heating and cooling applications in commercial/institutional and single family new construction as well as replacement and renovation markets. Based upon market data supplied by the Air-Conditioning, Heating and Refrigeration Institute (“AHRI”), we believe we have the leading market share.

Certain statements contained in this Part I may be deemed to be forward-looking statements. See “Special Note Regarding Forward-Looking Statements.”

Issuance of Senior Secured Notes, Intended Use of Proceeds and Amended Working Capital Revolver Loan

On August 7, 2013, LSB sold $425 million aggregate principal amount of the 7.75% Senior Secured Notes due 2019 (the “Senior Secured Notes”) in a private placement.

LSB has used or intends to use the proceeds, net of commissions and fees, from the sale of the Senior Secured Notes, as follows:

| • |  | $67.2 million was used to pay all outstanding borrowings, including the prepayment penalty, under a term loan agreement (the “Secured Term Loan”); and

| • |  | the balance is being used for general corporate purposes, including the construction of an ammonia plant, nitric acid plant, and concentrator at the El Dorado Facility; improvement of reliability, mechanical integrity, and safety at our chemical facilities; and the development of our acquired natural gas leaseholds during the next three years.

Using a portion of the net proceeds from the sale of the Senior Secured Notes, we are proceeding with the design, fabrication, engineering, and construction of an ammonia plant, a 65% strength nitric acid plant, and a 98% nitric acid concentrator at the El Dorado Facility. We have received the air permit from the Arkansas Department of Environmental Quality (“ADEQ”) for the construction of these plants.

Pending application of proceeds discussed above, the net proceeds from the Senior Secured Notes are currently invested in highly rated money market funds, certificates of deposit, and U.S. Treasury bills.

The Senior Secured Notes are jointly and severally and fully and unconditionally guaranteed by all of LSB’s subsidiaries and are collateralized with a substantial portion of LSB and most of its subsidiaries’ assets.

See further discussion relating to the use of actual proceeds received from the offering of our Senior Secured Notes in our Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”) contained in this report.

Current State of the Economy

Since our two core business segments serve several diverse markets, we consider fundamentals for each market individually as we evaluate economic conditions. From a macro standpoint, we believe the U.S. economy is poised for modest growth, based upon certain economic reports, including the Conference Board Composite Index of Leading Indicators.

Chemical Business - Our Chemical Business’ primary markets are agricultural, industrial and mining. During 2013, sales were $381 million or 20% lower than 2012. Due to the significant downtime at certain of our chemical facilities, as discussed below under “Downtime at Certain Chemical Facilities and Related Programs,” production and sales (in volumes and dollars) were lower in all three of our primary markets compared to the same period in 2012.

In normal circumstances, our agricultural sales volumes and prices depend upon the supply of and the demand for fertilizer, which in turn depends on the market fundamentals for crops including corn, wheat, cotton and forage. Although currently showing strength, nitrogen fertilizer prices are lower than the same time a year ago due in part to the significant increase in urea imports from China earlier during 2013. In addition, there was a significant increase in the 2013-2014 corn harvest and much lower forward corn prices as compared to a year ago. According to the USDA’s World Agricultural Supply and Demand Estimates, the U.S. yield per harvested acre of corn increased significantly from approximately 123 bushels per acre to 158 bushels per acre and the year end corn stocks were approximately double a year ago, resulting in a significant increase in the stock-to-use ratio. Notwithstanding the current conditions, the fundamentals continue to be positive for nitrogen fertilizer products we produce and sell and gross margins, although lower, are still strong. However, the fertilizer outlook could change if there are unanticipated changes in domestic fertilizer production capacity, acres planted of crops requiring fertilizer, unfavorable weather conditions or continued low selling prices and increases in imported urea from China. Our industrial acids sales volume is dependent upon general economic conditions primarily in the housing, automotive, and paper industries. According to the American Chemical Council, the outlook for these three sectors is generally positive. Our sales prices vary with the market price of our feedstock cost of ammonia or sulfur, as applicable, in our pricing arrangements with customers. Our mining sales volume is being impacted by lower customer demand for industrial grade AN, which we believe is primarily due to natural gas being a more attractive alternative feedstock than coal for utility companies. As reported by the U.S. Energy Information Administration, during 2013, coal production was down overall by 1.5%, although coal inventories declined by 43 million tons during the period. With such inventory decreases, the coal industry is now expected to see production growth of 3% to 4% in 2014 as inventories stabilize and short-term natural gas prices increase.

##### Table of Contents

We use natural gas to produce anhydrous ammonia in two of our four facilities, in which ammonia is used to produce nitrogen fertilizer and industrial products, and also sold in its original form. We also produce agricultural grade and industrial grade AN from purchased ammonia. The current cost of purchased ammonia is significantly higher than producing it from natural gas, resulting in a cost disadvantage compared to nitrogen fertilizers and industrial AN producers that manufacture from natural gas. We are proceeding with the design, fabrication, engineering and construction of an ammonia plant at the El Dorado Facility in order to eliminate this current cost disadvantage.

Climate Control Business—Sales for 2013 were $285 million, or 7% higher than 2012, including a 16% increase in hydronic fan coil sales and a 13% increase in geothermal and water source heat pump sales (both increases were associated with a higher number of units shipped, unit pricing and product mix) partially offset by a 23% decrease in other HVAC sales, primarily in sales of our large custom air handlers. From a market sector perspective, the sales increase was due to an 8% improvement in commercial/institutional product sales, and a 3% improvement in residential product sales. The improvement in commercial/institutional and residential sales in 2013 is primarily due to higher new construction activity in those sectors, which resulted in higher customer order intake in the preceding periods for our commercial/institutional products in most of our product lines. For 2013, order levels of our products decreased 2% in both residential products and commercial/institutional products. Information available from the McGraw-Hill Construction Market forecast indicates that construction activity for the markets we serve in the commercial/institutional and single-family residential sectors are expected to increase in aggregate during 2014 although still significantly below pre-recession levels. Also see discussion concerning certain heat pump contracts that will not be renewed in 2014 under risk factors under Item 1 and “Overview-Climate Control Business” of our MD&A contained in this report.

See further discussion relating to the economy under various risk factors under Item 1A of this Part 1 and “Overview-Economic Conditions” of our MD&A contained in this report.

Downtime at Certain Chemical Facilities and Related Programs

During 2012, 2013 and the first quarter of 2014, our Chemical Business encountered a number of significant issues. These issues included an explosion in one of our nitric acid plants at the El Dorado Facility in May 2012, a pipe rupture at the Cherokee Facility in November 2012 that damaged the ammonia plant, and the suspension of production at the Pryor Facility from time to time during 2012, 2013 and into the first quarter of 2014 due to continued mechanical issues. All of these issues resulted in lost production causing an adverse effect on our sales, operating income and cash flow for 2012, 2013 and the first quarter of 2014. See “Management Discussion and Analysis” contained herein for a discussion as to the negative effect that the downtime of the El Dorado Facility, Cherokee Facility, and Pryor Facility has had and will have on us.

Although these issues are unrelated to each other, the severity and frequency of the events at our Pryor, Cherokee, and El Dorado Facilities caused us to undergo a thorough reexamination of our process safety management (“PSM”), reliability and mechanical integrity programs. As a result, we have undertaken a concerted program to attempt to improve the reliability and mechanical integrity of our chemical plant facilities. The improvement program includes engaging outside experts and consultants who specialize in risk management, reliability, mechanical integrity and PSM. We are also recruiting and hiring additional corporate and plant engineering and operational personnel, and accelerating acquisition of additional spare parts to supplement our existing spare parts program. The program also includes the installation of additional automation and improved diagnostics.

See further discussion relating to the downtime at certain chemical facilities (and various risk factors associated with our chemical facilities), cumulative negative effect on our operating income as a result of the downtime at certain of our chemical plants, and our property and business interruption insurance claims and recoveries under our Management Discussion and Analysis contained in this report.

Segment Information and Foreign and Domestic Operations and Export Sales

Schedules of the amounts of net sales, gross profit, operating income and identifiable assets attributable to each of our lines of business and of the amount of our export sales in the aggregate and by major geographic area for each of the last three years appear in Note 18 of the Notes to Consolidated Financial Statements included elsewhere in this report.

Chemical Business

General

Our Chemical Business manufactures products for three principal markets:

| • |  | anhydrous ammonia, fertilizer grade AN, UAN, and ammonium nitrate ammonia solution for agricultural applications,

| • |  | high purity and commercial grade anhydrous ammonia, high purity AN, sulfuric acids, concentrated, blended and regular nitric acid, mixed nitrating acids, carbon dioxide, and DEF for industrial applications, and

| • |  | industrial grade AN and solutions for the mining industry.

During October 2012 and August 2013, a subsidiary within our Chemical Business acquired certain natural gas working interests totaling approximately 12% (approximately 10% net revenue interest) in certain natural gas properties located in the Marcellus Shale Formation in the state of Pennsylvania. Our working interest represents our share of the costs and expenses incurred primarily to develop the underlying leaseholds and to produce natural gas while our net revenue interest represents our share of the revenues from the sale of natural gas. The net revenue interest is less than our working interest as the result of royalty interest due to royalty owners. Since our Chemical Business purchases a significant amount of natural gas as a feedstock for the production of anhydrous ammonia, management considers these working interests as an economic hedge against a portion of a potential rise in natural gas prices in the future for a portion of our future natural gas feedstock requirements. We are not the operator of the wells included in these working interests and have no, or very limited, ability to direct the operations of these wells. We report the working interests as part of the Chemical Business reportable segment.

Market Conditions—Chemical Business

As discussed above and in more detail below under “Overview-Economic Conditions” of the MD&A contained in this report, agricultural volumes are driven by fertilizer demand, which depends upon acres planted of crops requiring fertilizer to enhance yield. We believe the current outlook indicates a strong demand for grains that should in turn result in strong demand for the types of nitrogen fertilizer we produce. The fertilizer outlook could change as the result of, among other things, changes in domestic fertilizer production capacity, acres planted of crops, weather conditions, commodity prices, and volume of imported agricultural products. The industrial and mining volumes are driven by general economic conditions, energy prices, and contractual arrangements with certain large customers.

Agricultural Products

Our Chemical Business produces UAN, agricultural grade AN, and anhydrous ammonia, all of which are nitrogen-based fertilizers. Farmers and ranchers decide which type of nitrogen-based fertilizer to apply based on the crop planted, soil and weather conditions, regional farming practices and relative nitrogen fertilizer prices. Our agricultural markets include a high concentration of pastureland and row crops, which favor our products. We sell these agricultural products to farmers, ranchers, fertilizer dealers and distributors primarily in the ranch land and grain production markets in the U.S. We develop our market position in these areas by emphasizing high quality products, customer service and technical advice. During the past few years, we have been successful in expanding outside our traditional markets by barging to distributors on the Tennessee and Ohio rivers, and by railing into certain Western States. Our historical sales of agricultural products are shown in the following table. The sales shown do not reflect amounts used internally, such as ammonia, in the manufacture of other products, or intercompany sales.

Our Chemical Business establishes long-term relationships with wholesale agricultural distributors and retailers and also sells directly to agricultural end-users through its network of wholesale and retail distribution centers. In addition, our Chemical Business sells at market prices substantially all of the UAN produced at the Pryor Facility pursuant to an agreement with a third-party purchaser. The term of the agreement is through June 2016, but may be terminated earlier by either party pursuant to the terms of the agreement.

Industrial Acids and Other Chemical Products

Our Chemical Business manufactures and sells industrial acids and other chemical products primarily to the polyurethane, paper, fibers, emission control, and electronics industries. In addition, our Chemical Business produces and sells blended and regular nitric acid. Our Chemical Business is also a niche market supplier of industrial and high purity ammonia for many specialty applications, including the reduction of air emissions from power plants.

We believe the Baytown Facility is one of the newest, largest and one of the most technologically advanced nitric acid manufacturing units in the U.S., with demonstrated capacity exceeding 1,350 short tons per day. The operations of the Baytown Facility have been recognized in several publications and received numerous awards for safety and environmental leadership. The majority of the Baytown Facility’s production is sold to Bayer Material Science, LLC pursuant to a long-term contract (the “Bayer Agreement”) that provides for a pass-through of certain costs, including the anhydrous ammonia costs, plus a profit. The term of the Bayer Agreement is through June 2021.

Our Chemical Business competes based upon service, price, location of production and distribution sites, product quality and performance and provides inventory management as part of the value-added services offered to certain customers.

Mining Products

Our Chemical Business manufactures industrial grade AN and 83% AN solution for the mining industry. Pursuant to a long-term cost-plus supply agreement (the “Orica Agreement”), our Chemical Business sells to Orica International Pte Ltd. industrial grade AN produced at the El Dorado Facility. The agreement includes certain minimum payment obligations and requires a minimum one-year notice of termination, with the termination date to be no sooner than April 9, 2015.

LSB’s consolidated net sales |  |  | 6 | % |  |  | 9 | % |  |  | 11 | %

Raw Materials—Chemical Business

The products our Chemical Business manufactures are primarily derived from the following raw material feedstocks: anhydrous ammonia and natural gas. These raw material feedstocks are commodities, subject to price fluctuations.

The El Dorado Facility normally purchases approximately 200,000 tons of anhydrous ammonia annually and produces and sells approximately 470,000 tons of nitrogen-based products per year, if the facility is in production for the full year. Although anhydrous ammonia is produced from natural gas, the price does not necessarily follow the spot price of natural gas in the U.S. Anhydrous ammonia is an internationally traded commodity and the relative price is set in the world market while natural gas is primarily a nationally traded commodity. The ammonia supply to the El Dorado Facility is transported from the Gulf of Mexico by pipeline. Under an agreement with its principal supplier of anhydrous ammonia, our subsidiary, El Dorado Chemical Company (“EDC”), will purchase a majority of its anhydrous ammonia requirements through December 2015 from this supplier. We believe that we can obtain anhydrous ammonia from other sources in the event of an interruption of service under the above-referenced contract.

The Cherokee Facility normally purchases 5 million to 6 million MMBtu of natural gas to produce and sell approximately 300,000 to 370,000 tons of nitrogen-based products per year, if the facility is in production for the full year. Natural gas is the primary raw material for producing anhydrous ammonia, UAN and other products at this facility. Periodically, the Cherokee Facility purchases anhydrous ammonia to supplement its annual production capacity of approximately 175,000 tons. Anhydrous ammonia can be delivered to the Cherokee Facility by truck, rail or barge.

If the Pryor Facility is in production for a full year, it will normally purchase 5 million to 6 million MMBtu of natural gas to produce and sell approximately 300,000 to 335,000 tons of nitrogen-based products per year.

The Cherokee and Pryor Facilities’ natural gas feedstock requirements are generally purchased at spot market price. Periodically, we will enter into firm purchase commitments and/or futures/forward contracts to economically hedge the cost of certain of the natural gas requirements. We believe that our investment in natural gas working interest in the Marcellus Shale Formation will provide a partial hedge for the cost of this key raw material.

The Baytown Facility consumes more than 125,000 tons of purchased anhydrous ammonia per year; however, the majority of the Baytown Facility’s production is sold under the Bayer Agreement that provides for a pass-through of certain costs, including the anhydrous ammonia costs, plus a profit.

As of February 14, 2014, the published price, as described above, for ammonia was $415 per metric ton and natural gas was $5.53 per MMBtu.

See further discussion relating to the outlook for the Chemical Business in our MD&A contained in this report.

Strategy—Chemical Business

Our Chemical Business has pursued a strategy of developing industrial and mining customers that purchase substantial quantities of products, including contractual obligations to purchase minimum quantities and pricing arrangements that provide for the pass through of raw material and other manufacturing costs. These arrangements help mitigate the volatility risk inherent in the raw material feedstocks and/or the changes in demand for our products. For 2013, approximately 54% of the Chemical Business’ sales were into industrial and mining markets of which approximately 57% of these sales were pursuant to these types of arrangements. Approximately 44% of our 2013 sales were into agricultural markets primarily at the price in effect at time of sale. Periodically, we enter into firm purchase commitments and/or futures/forward contracts to economically hedge the cost of natural gas for the purpose of securing the profit margin on a certain portion of our firm sales price commitments in our Chemical Business. Also see our discussion above concerning acquisitions of working interests in certain natural gas properties.

The spot sales prices of our agricultural products may not have a correlation to the anhydrous ammonia and natural gas feedstock costs but rather reflect market conditions for like and competing nitrogen sources. This lack of correlation can compromise our ability to recover our full cost to produce the product in this market. Additionally, the lack of sufficient non-seasonal sales volume to operate our manufacturing facilities at optimum levels can preclude the Chemical Business from reaching full performance potential. Looking forward, we are pursuing profitable growth of our Chemical Business including the potential to increase the output of our existing production facilities. See further discussion under “Capital Expenditures” of our MD&A contained in this report. Our strategy also calls for increased emphasis on the agricultural sector, while remaining committed to further developing industrial customers who assume the volatility risk associated with the cost of natural gas and ammonia and mitigate the effects of seasonality in the agricultural sector.

Our strategy is also to invest in projects that we believe will generate the best returns for our stockholders taking into consideration the risk and return on investment. This strategy motivated our decision to build the ammonia plant at the El Dorado Facility and construct a new nitric acid plant and concentrator to replace the productive capacity lost when the El Dorado Facility strong nitric acid plant was damaged in 2012. We believe that upon completion of the ammonia plant and the nitric acid plant and concentrator, the El Dorado Facility will benefit from reduced feedstock costs, expanded capacity, improved efficiency and product mix flexibility.

Seasonality—Chemical Business

We believe that the only significant seasonal products that we market are fertilizer and related chemical products sold by our Chemical Business to the agricultural industry. The selling seasons for those products are primarily during the spring and fall planting seasons, which typically extend from March through June and from September through November in the geographical markets in which the majority of our agricultural products are distributed. As a result, our Chemical Business typically increases its inventory of AN and UAN prior to the beginning of each planting season. In addition, the amount and timing of sales to the agricultural markets depend upon weather conditions and other circumstances beyond our control.

Regulatory Matters—Chemical Business

Our Chemical Business is subject to extensive federal, state and local environmental laws, rules and regulations as discussed under “Environmental, Health and Safety Matters” of this Item 1 and various risk factors under Item 1A.

Competition—Chemical Business

Our Chemical Business competes with several chemical companies in our markets, such as Agrium, CF Industries, Coffeyville Resources, Dyno Nobel, Koch, Potash Corporation of Saskatchewan, and Yara International (some of whom are our customers), many of whom have greater financial and other resources than we do. We believe that competition within the markets served by our Chemical Business is primarily based upon service, price, location of production and distribution sites, and product quality and performance.

Climate Control Business

General

Our Climate Control Business manufactures and sells a broad range of standard and custom designed geothermal and water source heat pumps and hydronic fan coils as well as large custom air handlers and modular chiller systems, including modular geothermal chillers and simultaneous heating and cooling modules. These products are for use in commercial/institutional and residential HVAC systems. Our products are installed in some of the most recognizable commercial/institutional developments in the U.S., including the Prudential Tower, Rockefeller Plaza, Trump Tower, Time Warner Center and many others. In addition, we have a significant presence in the lodging sector with installations in numerous Hyatt, Marriott, Four Seasons, Starwood, Ritz Carlton, Wynn, and Hilton hotels, among others.

The following table summarizes net sales information relating to our products of the Climate Control Business:

Market Conditions—Climate Control Business

Information available from the McGraw-Hill Construction Market forecast indicates that construction activity for the primary markets we serve in the commercial/industrial sector are expected to increase in aggregate during 2014 by approximately 9% (measured in dollars), remaining significantly below pre-recession levels. The McGraw-Hill Construction Market forecast has indicated construction growth in the single-family residential sector for 2014 of approximately 22% (measured in new housing units), also remaining significantly below pre-recession levels.

In addition, we believe that tax credits and incentives contained in the American Reinvestment and Recovery Act of 2009, have and could continue to stimulate sales of our geothermal heat pump products, as well as other “green” products.

Geothermal and Water Source Heat Pumps

We believe our Climate Control Business is a leading provider of geothermal and water source heat pumps to the commercial/institutional construction and renovation markets in the U.S.

Water source heat pumps are highly efficient heating and cooling products, which can enable individual room climate control through the transfer of heat using a water pipe system connected to a centralized cooling tower or heat injector. Water source heat pumps enjoy a broad range of commercial/institutional applications, particularly in medium to large sized buildings with many small, individually controlled spaces. We believe the market share for commercial/institutional water source heat pumps, relative to other types of heating and air conditioning systems, should continue to grow due to the relative efficiency and longevity of such systems, as well as the replacement market for those systems.

We also provide geothermal heat pumps in residential and commercial/institutional applications. Geothermal systems, which circulate water or a combination of water and antifreeze through an underground heat exchanger, are considered to be the most energy efficient systems currently available in the market. We believe the energy efficiency and longer life of geothermal systems, as compared with other systems, as well as tax incentives that are available to homeowners and businesses when installing geothermal systems, will increase demand for our geothermal products. Our products are sold to the commercial/institutional markets, as well as single and multi-family residential new construction, renovation and replacements.

Hydronic Fan Coils

We believe that our Climate Control Business is a leading provider of hydronic fan coils targeting commercial and institutional markets. Hydronic fan coils use heated or chilled water provided by a centralized chiller and/or boiler, through a water pipe system, to condition the air and allow individual room control. Hydronic fan coil systems are quieter, have longer lives and lower maintenance costs than other comparable systems used where individual room control is required. Important components of our strategy for competing in the commercial/institutional renovation and replacement markets include the breadth of our product line coupled with customization capability provided by a flexible manufacturing process. Hydronic fan coils enjoy a broad range of commercial/institutional applications, particularly in medium to large sized buildings with many small, individually controlled spaces.

Production and Backlog—Climate Control Business

We manufacture our products in many sizes and configurations, as required by the purchaser, to fit the space and capacity requirements of hotels, motels, schools, hospitals, apartment buildings, office buildings and other commercial/institutional or residential structures. Most customers place their product orders well in advance of required delivery dates.

The backlog of confirmed customer product orders (purchase orders from customers that have been accepted and received credit approval) for our Climate Control Business was approximately $39.7 million and $55.5 million as of December 31, 2013 and 2012, respectively. The lower backlog in 2013 was due to sales exceeding order levels for both commercial/institutional and residential products during 2013. The backlog of product orders generally does not include amounts relating to shipping and handling charges, service orders or service contract orders. The backlog also excludes contracts for our construction business due to the relative size of individual projects and, in some cases, extended timeframe for completion beyond a twelve-month period.

Historically, we have not experienced significant cancellations relating to our backlog of confirmed customer product orders. We expect to ship substantially all of these orders within the next twelve months; however, it is possible that some of our customers could cancel a portion of our backlog or extend the shipment terms.

Distribution—Climate Control Business

Our Climate Control Business sells its products primarily to mechanical contractors, original equipment manufacturers (“OEMs”) and distributors. Our sales to mechanical contractors primarily occur through independent manufacturers’ representatives, who also represent complementary product lines not manufactured by us. OEMs generally consist of other air conditioning and heating equipment manufacturers who resell under their own brand name the products purchased from our Climate Control Business. As previously reported, in November 2013, Carrier Corporation (“Carrier”), which is one of our OEMs, advised one of our subsidiaries, Climate Master, Inc. (“CM”), that the heat pump contracts will not be renewed between

##### Table of Contents

CM, as the manufacturer, and Carrier, as the purchaser, effective May 11, 2014. During 2013, 2012 and 2011, net sales pursuant to these heat pump contracts represented less that 5% of LSB’s consolidated net sales during each of those periods. See addition discussions concerning these heat pump contracts under “Risk Factors – A substantial portion of our sales is dependent upon a limited number of customers” under Item 1A and “Overview-Climate Control Business” of our MD&A contained in this report. The following table summarizes net sales to OEMs relating to our products of the Climate Control Business:

Market—Climate Control Business

Our Climate Control Business market includes commercial/institutional and residential new building construction, renovation of existing buildings and replacement of existing systems. This includes, but is not limited to, custom designed geothermal and water source heat pumps, hydronic fan coils, large custom air handlers, modular chiller systems including geothermal chillers and simultaneous heating and cooling modules in markets such as education, single-family residential, multi-family residential, hospitality, healthcare, retail, and government.

Raw Materials and Components—Climate Control Business

Numerous domestic and foreign sources exist for the materials and components used by our Climate Control Business, which include compressors, copper, steel, electric motors, valves and aluminum. Periodically, our Climate Control Business enters into futures contracts for copper. We do not anticipate any difficulties in obtaining necessary materials and components for our Climate Control Business. Although we believe we will be able to pass to our customers the majority of any cost increases in the form of higher prices, the timing of these price increases could lag the increases in the cost of materials and components. While we believe we will have sufficient sources for materials and components, a shortage could impact production of our Climate Control products.

Market—Climate Control Business

Our Climate Control Business competes with several companies, primarily Carrier, Nortek, Trane, McQuay, Energy Labs, and Bosch, some of whom are also our customers. Some of our competitors serve other markets and have greater financial and other resources than we do. We believe our Climate Control Business manufactures a broader line of geothermal and water source heat pump and fan coil products than any other manufacturer in the U.S. and that we are competitive as to price, service, warranty and product performance.

Strategy—Climate Control Business

Based on business plans and key objectives submitted by subsidiaries within our Climate Control Business, we expect to continue to launch new products and product upgrades in an effort to maintain and increase our current market position and to establish a presence in new markets served by the Climate Control Business. Further, our plan to drive growth in our Climate Control Business includes:

| • |  | focusing on product niches;

| • |  | continuing to develop the market for geothermal products, as well as products for green and energy-efficient construction retrofit; and

| • |  | continuing to focus on operational excellence

Employees

As of December 31, 2013, we employed 1,885 persons. As of that date, our Chemical Business employed 530 persons, with 156 represented by unions under agreements that expire in November of 2016 through October of 2018, and our Climate Control Business employed 1,266 persons, none of whom were represented by a union.

Environmental, Health and Safety Matters

Our facilities and operations are subject to numerous federal, state and local environmental laws (“Environmental Laws”) and to other laws regarding health and safety matters (“Health Laws”). In particular, the manufacture, production and distribution of products by our Chemical Business are activities that entail environmental and public health risks and impose obligations under the Environmental Laws and the Health Laws, many of which provide for certain performance obligations, substantial fines and criminal sanctions for violations. There can be no assurance that we will not incur material costs or liabilities in complying with such laws or in paying fines or penalties for violation of such laws. The Environmental Laws and Health Laws and enforcement policies thereunder have in the past resulted, and could in the future result, in significant compliance expenses, cleanup costs (for our sites or third-party sites where our wastes were disposed of), penalties or other liabilities relating to the handling, manufacture, use, emission, discharge or disposal of hazardous or toxic materials at or from our facilities or the use or disposal of certain of its chemical products. Historically, significant expenditures have been incurred by subsidiaries within our Chemical Business in order to comply with the Environmental Laws and Health Laws and are reasonably expected to be incurred in the future. We will also be obligated to manage certain discharge water outlets and monitor groundwater contaminants at our Chemical Business facilities should we discontinue the operations of a facility. We do not operate the natural gas wells where we own an interest and compliance with Environmental Laws and Health Laws is controlled by others, with our Chemical Business being responsible for its proportionate share of the costs involved. As of December 31, 2013, our accrued liabilities for environmental matters totaled $1,234,000 relating primarily to matters discussed below. It is reasonably possible that a change in the estimate of our liability could occur in the near term. Also see discussion concerning AROs under “Management’s Discussion and Analysis of Financial Condition and Results of Operations–Critical Accounting Policies and Estimates.”

Discharge Water Matters

Each of our chemical manufacturing facilities generates process wastewater, which may include cooling tower and boiler water quality control streams, contact storm water (rain water inside the facility area that picks up contaminants) and miscellaneous spills and leaks from process equipment. The process water discharge, storm-water runoff and miscellaneous spills and leaks are governed by various permits generally issued by the respective state environmental agencies as authorized by the U.S. Environmental Protection Agency (“EPA”), subject to oversight by the EPA. These permits limit the type and amount of effluents that can be discharged and controls the method of such discharge. The following are discharge water matters in relation to the respective permits.

The El Dorado Facility is subject to a state National Pollutant Discharge Elimination System (“NPDES”) discharge water permit issued by the Arkansas Department of Environmental Quality (“ADEQ”). The El Dorado Facility is currently operating under an NPDES discharge water permit, which became effective in 2004 (“2004 NPDES permit”). In November 2010, a preliminary draft of a discharge water permit renewal for the El Dorado Facility, which contains more restrictive limits, was issued by the ADEQ.

EDC believes that the El Dorado Facility has generally demonstrated its ability to comply with applicable ammonia and nitrate permit limits, but has, from time to time, had difficulty demonstrating consistent compliance with the more restrictive dissolved minerals permit levels. As part of the El Dorado Facility’s long-term compliance plan, EDC has pursued a rulemaking and permit modification with the ADEQ as to the discharge requirements relating to its dissolved minerals. The ADEQ approved a rule change, but the EPA formally disapproved the rule change. In October 2011, EDC filed a lawsuit against the EPA in the United States District Court, El Dorado, Arkansas, appealing the EPA’s decision disapproving the rule change. In March 2013, the District Court affirmed the EPA’s decision. EDC has appealed the District Court’s decision. We do not believe this matter regarding meeting the permit requirements as to the dissolved minerals will continue to be an issue now that the pipeline discussed below is operational and EDC’s right to use the pipeline to dispose of its wastewater.

During 2012, EDC paid a penalty of $100,000 to settle an Administrative Complaint issued by the EPA, and thereafter handled by the United States Department of Justice (“DOJ”), relating to certain alleged violations of EDC’s 2004 NPDES permit for alleged violations through December 31, 2010. The DOJ advised that some action would be taken for alleged violations occurring after December 31, 2010. As of the date of this report, no action has been filed by the DOJ. The cost (or range of costs) cannot currently be reasonably estimated regarding this matter. Therefore, no liability has been established at December 31, 2013.

11

##### Table of Contents

During 2013, the City of El Dorado, Arkansas (the “City”) completed the construction of a pipeline for disposal of wastewater generated by the City and by certain companies in the El Dorado area. EDC and other companies in the El Dorado area entered into a funding agreement and operating agreement with the City, pursuant to which each party agreed to contribute to the cost of construction and the annual operating costs of the pipeline for the right to use the pipeline to dispose its wastewater. EDC believes that the disposal of wastewater through this pipeline will enable EDC to comply with water discharge permit limits under current and foreseeable regulations. The City completed the construction of the pipeline and EDC began utilizing the pipeline during 2013. The initial term of the operating agreement is through December 2053.

In addition, the El Dorado Facility is currently operating under a consent administrative order (“2006 CAO”) that recognizes the presence of nitrate contamination in the shallow groundwater. The 2006 CAO required EDC to continue semiannual groundwater monitoring, to continue operation of a groundwater recovery system and to submit a human health and ecological risk assessment to the ADEQ relating to the El Dorado Facility. The final remedy for shallow groundwater contamination, should any remediation be required, will be selected pursuant to a new consent administrative order and based upon the risk assessment. The cost of any additional remediation that may be required will be determined based on the results of the investigation and risk assessment, of which cost (or range of costs) cannot currently be reasonably estimated. Therefore, no liability has been established at December 31, 2013, in connection with this matter.

Air Matters

In connection with a national enforcement initiative, the EPA had sent information requests to most, if not all, of the operators of nitric acid plants in the U.S., including our El Dorado Facility, our chemical production facility located in Cherokee, Alabama (the “Cherokee Facility”) and the Baytown Facility operated by our subsidiary, EDN, under Section 114 of the Clean Air Act as to construction and modification activities at each of these facilities over a period of years.

During 2013, we negotiated a global agreement in principle with the EPA/DOJ to settle this matter. During January 2014, we executed a formal Consent Decree to settle this matter and expect the DOJ to execute such and to obtain court approval of the executed Consent Decree to become effective during 2014. The agreement provides, among other things, the following:

| • |  | all of our Chemical Business’ nitric acid plants are to achieve certain emission rates within a certain time period for each plant. In order to achieve these emission rates, six of our Chemical Business’ eight nitric acid plants will require additional pollution control technology equipment to achieve the emission rates agreed upon. Currently, we have already completed necessary modifications at three of our Chemical Business’ existing nitric acid plants. The cost of the necessary pollution control equipment is estimated to range from $2.0 million to $3.0 million for each of the remaining five nitric acid plants, the cost of which will be capitalized when incurred;

| • |  | our Chemical Business will provide a reforestation mitigation project that is unrelated to our emissions or activities and will not be located at one of our plant sites, which we estimate will cost approximately $150,000 and have included this amount in our accrued liabilities for environmental matters discussed above; and

| • |  | a civil penalty will be paid by our Chemical Business in the amount of $725,000 (which includes the $100,000 civil penalty to the ODEQ discussed below), which amount is included in our accrued liabilities for environmental matters discussed above.

One of our subsidiaries, Pryor Chemical Company (“PCC”), within our Chemical Business, has been advised that the Oklahoma Department of Environmental Quality (“ODEQ”) is conducting an investigation into whether the chemical production facility located in Pryor, Oklahoma (the “Pryor Facility”) was in compliance with certain rules and regulations of the ODEQ and whether PCC’s reports of certain air emissions relating primarily to 2011 were intentionally reported incorrectly to the ODEQ. Pursuant to the request of the ODEQ, PCC submitted information and a report to the ODEQ as to the reports filed by the Pryor Facility relating to the air emissions in question. Investigators with the ODEQ obtained documents from the Pryor Facility in connection with this investigation pursuant to a search warrant and interviewed several employees at the facility. PCC has cooperated with the ODEQ in connection with this investigation. We are not aware of any recommendations made or to be made by the ODEQ with respect to formal legal action to be taken or recommended as a result of this ongoing investigation.

By letter dated April 19, 2013 (the “letter”), ODEQ, based on its inspection of our Pryor Facility conducted in December 2012, identified fourteen issues of alleged non-compliance and concern from the evaluation relating to federal and state air quality regulations, some of which were the subject of the ongoing investigation by ODEQ described above. PCC engaged in

12

##### Table of Contents

discussions with ODEQ and a settlement was reached to resolve the allegations identified in the letter. Three of the violations were resolved through the global settlement with the EPA/DOJ discussed above, and ODEQ agreed to resolve the remaining eleven violations by PCC paying a civil penalty for $100,000 (which amount is included in the $725,000 civil penalty discussed above) with the settlement being addressed as an addition to the global settlement discussed above. This settlement is unrelated to the pending ODEQ investigation at the Pryor Facility described above, which remains ongoing to our knowledge.

Other Environmental Matters

In 2002, two subsidiaries within our Chemical Business sold substantially all of their operating assets relating to a Kansas chemical facility (“Hallowell Facility”) but retained ownership of the real property. Even though we continued to own the real property, we did not assess our continuing involvement with our former Hallowell Facility to be significant and therefore accounted for the sale as discontinued operations. Our subsidiary retained the obligation to be responsible for, and perform the activities under, a previously executed consent order to investigate the surface and subsurface contamination at the real property and a corrective action strategy based on the investigation. In addition, certain of our subsidiaries agreed to indemnify the buyer of such assets for these environmental matters. Based on the assessment discussed above, we account for transactions associated with the Hallowell Facility as discontinued operations.

The successor (“Chevron”) of a prior owner of the Hallowell Facility has agreed in writing, on a nonbinding basis and within certain other limitations, to pay and has been paying one-half of the costs of the interim measures relating to this matter as approved by the Kansas Department of Environmental Quality, subject to reallocation.

Our subsidiary and Chevron are pursuing with the state of Kansas a course of long-term surface and groundwater monitoring to track the natural decline in contamination. Currently, our subsidiary and Chevron are in the process of performing additional surface and groundwater testing.

In addition during 2010, the Kansas Department of Health and Environment (“KDHE”) notified our subsidiary and Chevron that the Hallowell Facility has been referred to the KDHE’s Natural Resources Trustee, who is to consider and recommend restoration, replacement and/or whether to seek compensation. KDHE will consider the recommendations in its evaluation. Currently, it is unknown what damages the KDHE would claim, if any. The ultimate required remediation, if any, is unknown.

The nature and extent of a portion of the requirements are also not currently defined, and the associated costs (or range of costs) are not currently reasonably estimable. Therefore, no liability has been established at December 31, 2013, in connection with the KDHE’s Natural Resources Trustee matter.

ITEM 1A. RISK FACTORS

Risks Related to Our Business and Industry

Our Chemical and Climate Control Businesses and their customers are sensitive to adverse economic cycles.

Our Chemical Business can be affected by cyclical factors such as inflation, global energy policy and costs, global market conditions and economic downturns in specific industries. Certain sales of our Chemical Business are sensitive to the level of activity in the agricultural, mining, automotive and housing industries. A substantial decline in the activity of our Chemical Business has in the past, and could in the future, have a material adverse effect on the results of our Chemical Business and on our liquidity and capital resources. Further, material economic changes that adversely affect our natural gas working interests or lower natural gas prices may require us to write down the carrying value of our natural gas working interests. Therefore, these changes in our Chemical Business could adversely impact our operating results, liquidity and financial condition.

Our Climate Control Business also can be affected by cyclical factors, such as interest rates, inflation and economic downturns. Our Climate Control Business depends on sales to customers in the construction and renovation industries, which are particularly sensitive to these factors. A decline in the economic activity in the U.S. has in the past, and could in the future, have a material adverse effect on us and our customers in the construction and renovation industries in which our Climate Control Business sells a substantial amount of its products. Such a decline could result in a decrease in revenues and profits, and an increase in bad debts that could have a material adverse effect on our operating results, financial condition and liquidity.

##### Table of Contents

Weather conditions adversely affect our Chemical Business.

The agricultural products produced and sold by our Chemical Business have been in the past, and could be in the future, materially affected by adverse weather conditions (such as excessive rain or drought) in the primary markets for our fertilizer and related agricultural products. If any of these unusual weather events occur during the primary seasons for sales of our agricultural products (March-June and September-November), this could have a material adverse effect on the agricultural sales of our Chemical Business and our financial condition and results of operations.

Despite continuing investment to upgrade and replace equipment on an ongoing basis, the age of facilities of our Chemical Business increases the risk for unplanned downtime which may be significant.

Our Chemical Business is comprised of operating units of various ages and levels of automated control. While we have continued to make significant annual capital improvements, potential age or control related issues have occurred in the past and may occur in the future, which could cause damage to the equipment and ancillary facilities. For example, during 2013, certain of our chemical facilities had planned and unplanned downtime as a result of certain maintenance and equipment issues. It is customary when performing major equipment replacements at a facility for there to be subsequent unplanned downtime in order to ensure the facility is running at appropriate operating conditions. As a result, we have and may continue to experience additional downtime at our chemical facilities in the future.

The equipment required for the manufacture of our chemical products is specialized, and the time for replacement of such equipment can be lengthy, resulting in extended downtime in the affected unit. Although we utilize various reliability and inspection programs and maintain a significant inventory of spare equipment, which are intended to mitigate the extent of production losses, unplanned outages may still occur. As a result, these planned and unplanned downtime events at our chemical facilities have in the past and could in the future adversely impact our operating results, liquidity and financial condition.

Current and future legislative or regulatory requirements impacting our Chemical Business may result in increased costs and decreased revenues, cash flows and liquidity or could have other negative impacts on our Chemical Business.

Our businesses are subject to numerous health, safety, security and environmental laws and regulations, primarily relating to our Chemical Business. The manufacture and distribution of chemical products are activities which entail health, safety and environmental risks and impose obligations under health, safety and environmental laws and regulations, many of which provide for substantial fines and potential criminal sanctions for violations. Although we believe we have established processes to monitor, review and manage our businesses to comply with the numerous health, safety and environmental laws and regulations, our Chemical Business has in the past, and may in the future, be subject to fines, penalties and sanctions for violations and substantial expenditures for cleanup costs and other liabilities relating to the handling, manufacture, use, emission, discharge or disposal of effluents at or from the Chemical Business’ facilities. Further, a number of our Chemical Business’ facilities are dependent on environmental permits to operate, the loss or modification of which could have a material adverse effect on their operations and our financial condition.

Changes to the production equipment at our chemical facilities as may be required in order to comply with health, safety and environmental regulations may require substantial capital expenditures.

Explosions and/or losses at other chemical facilities not owned by us could also result in new or additional legislation or regulatory changes, particularly relating to public health and safety, that could negatively impact our Chemical Business.

In summary, new or changed laws and regulations could have an adverse effect on our operating results, liquidity and financial condition.

We may be required to modify or expand our operating, sales and reporting procedures and install additional equipment for our Chemical Business in order to comply with current and possible future government regulations.

The chemical industry in general, and producers and distributors of anhydrous ammonia and AN specifically, are scrutinized by the government, industry and public on security issues. Under current and proposed regulations, we may be required to incur substantial additional costs relating to security at our chemical facilities and distribution centers, as well as in the

14

##### Table of Contents

transportation of our products. These costs could have a material impact on our financial condition, results of operations, and liquidity. The cost of such regulatory changes, if significant enough, could lead some of our customers to choose alternate products to anhydrous ammonia and AN, which would have a significant impact on our Chemical Business.

In order to comply with the “Secure Handling of Ammonium Nitrate Act of 2007” as enacted by the U.S. Congress, the U.S. Department of Homeland Security (“DHS”) has published in the August 3, 2011 Federal Register a Notice of Proposed Rulemaking. This regulation proposes to require sellers, buyers, their agents and transporters of solid AN and certain solid mixtures containing AN to possess a valid registration issued by DHS, keep certain records, report the theft or unexplained loss of regulated materials and certain other new requirements. We and other parties affected by this proposal have submitted appropriate comments to DHS regarding the proposed regulation. Depending on the provisions of the final regulation to be promulgated by DHS and on our ability to pass these costs to our customers, these requirements may have a negative effect on the profitability of our AN business and may result in fewer distributors who are willing to handle the product. It is reasonably possible that compliance with the final regulation may be required during 2014.

On August 1, 2013, the Obama Administration issued Executive Order 13650 addressing the safety and security of chemical facilities in response to recent incidents involving chemicals such as the April 2013 explosion at West, Texas. The Obama Administration is directing federal agencies to enhance existing regulations and make recommendations to the U.S. Congress to develop new laws that may affect our Chemical Business.

Proposed governmental laws and regulations relating to greenhouse gas emissions may subject certain of our Chemical Business’ facilities to significant new costs and restrictions on their operations and reduction in sales.

The manufacturing facilities within our Chemical Business use significant amounts of electricity, natural gas and other raw materials necessary for the production of their chemical products that result, or could result, in certain greenhouse gas emissions into the environment. Federal and state courts and administrative agencies, including the EPA, are considering the scope and scale of greenhouse gas emission regulation. Legislation is being considered that would regulate greenhouse gas emissions at some point in the future for our facilities and has already impacted certain of our customers leading to closure or rate reductions of certain facilities. The EPA has instituted a mandatory greenhouse gas reporting requirement that began in 2010, which impacts all of our chemical manufacturing sites. Greenhouse gas regulation could increase the price of the electricity and other energy sources purchased by our chemical facilities; increase costs for natural gas and other raw materials (such as anhydrous ammonia); potentially restrict access to or the use of certain raw materials necessary to produce our chemical products; and require us to incur substantial expenditures to retrofit our chemical facilities to comply with the proposed new laws and regulations regulating greenhouse gas emissions, if adopted. Federal, state and local governments may also pass laws mandating the use of alternative energy sources, such as wind power and solar energy, which may increase the cost of energy use in certain of our chemical and other manufacturing operations. As it relates to our Chemical Business’ working interest in natural gas properties, legislative and regulatory proposals for restricting greenhouse gas emissions or otherwise addressing climate change could require our Chemical Business to incur additional operating costs and could adversely affect demand for the natural gas that the operator of these wells intends to sell. While future emission regulations or new laws appear possible, it is difficult to predict how these regulations, if and when adopted, will affect our businesses, operations, liquidity or financial results.

There is intense competition in the Climate Control and Chemical industries.

Substantially all of the markets in which we participate are highly competitive with respect to product quality, price, design innovations, distribution, service, warranties, reliability and efficiency. We compete with a number of companies, domestic and foreign, that have greater financial, marketing and other resources. Competitive factors could require us to reduce prices or increase spending on product development, marketing and sales that would have a material adverse effect on our business, results of operation and financial condition.

A substantial portion of our sales is dependent upon a limited number of customers.

For 2013, six customers of our Chemical Business accounted for approximately 50% of its net sales and 28% of our consolidated net sales, and our Climate Control Business had one customer, Carrier Corporation (“Carrier”), including affiliates and their distributors, that accounted for approximately 15% of its net sales and 6% of our consolidated net sales. During the latter part of 2013, Carrier Corporation (“Carrier”) advised our Climate Control Business that effective May 11, 2014, that Carrier will not be renewing the contracts to purchase heat pumps from our Climate Control Business. During 2013,

15

##### Table of Contents

net sales of heat pumps to Carrier represented approximately 5% of our 2013 consolidated net sales. The loss of, or a material reduction in purchase levels by, one or more of these customers could have a material adverse effect on our business and our results of operations, financial condition and liquidity if we are unable to replace a customer with other sales on substantially similar terms.

Cost and the lack of availability of raw materials could materially affect our profitability and liquidity.

Our sales and profits are heavily affected by the costs and availability of primary raw materials. These primary raw materials are subject to considerable price volatility. Historically, when there have been rapid increases in the cost of these primary raw materials, we have sometimes been unable to timely increase our sales prices to cover all of the higher costs incurred. While we periodically enter into futures/forward contracts to economically hedge against price increases in certain of these raw materials, there can be no assurance that we will effectively manage against price fluctuations in those raw materials.

Anhydrous ammonia and natural gas represent the primary raw material feedstocks in the production of most of the products of the Chemical Business. Although our Chemical Business enters into contracts with certain customers that provide for the pass-through of raw material costs, we have a substantial amount of sales that do not provide for the pass-through of raw material costs. In addition, the Climate Control Business depends on raw materials such as copper and steel, which have shown considerable price volatility. As a result, in the future, we may not be able to pass along to all of our customers the full amount of any increases in raw material costs. There can be no assurance that future price fluctuations in our raw materials will not have an adverse effect on our financial condition, liquidity and results of operations.

As stated above, natural gas represents one of the primary raw materials in the production of our Chemical Business’ products, and, as a result, we acquired natural gas working interests as an economic hedge against rising prices for natural gas. Our natural gas working interests may not be effective as an economic hedge under certain limited conditions.

We do not operate our natural gas working interest properties and have no, or very limited, ability to exercise influence over operations of these properties or their associated cost.

Since we source certain of our raw materials and components on a global basis, we may experience long lead times in procuring those raw materials and components purchased overseas, as well as being subject to tariff controls and other international trade barriers, which may increase the uncertainty of raw material and component availability and pricing volatility.

Additionally, we depend on certain vendors to deliver the primary raw materials and other key components that are required in the production of our products. Any disruption in the supply of the primary raw materials and other key components could result in lost production or delayed shipments. We have suspended in the past, and could suspend in the future, production at our chemical facilities due to, among other things, the high cost or lack of availability of such primary raw materials, which could adversely impact our competitiveness in the markets we serve. Accordingly, our financial condition, liquidity and results of operations could be materially affected in the future by the lack of availability of primary raw materials and other key components and increase costs relating to the purchase of raw materials or the production of our natural gas working interests.

Potential increase of imported agricultural products.

Russia and Ukraine both have substantial capacity to produce and export fertilizer grade ammonium nitrate (“AN”). Producers in these countries also benefit from below-market prices for natural gas, due to Government regulation and other factors. Fertilizer grade AN imports from Russia and Ukraine are currently subject to U.S. antidumping duty orders, which require these imports to be sold in the U.S. market at a fair value. Currently, all imports of fertilizer grade AN from Russia are subject to an antidumping duty rate of 254% and all imports of fertilizer grade AN from Ukraine are subject to an antidumping duty rate of 156%. The antidumping orders have substantially restrained the volumes of these imports. We have been recently notified that the U.S. Department of Commerce (“Commerce”) has refused to investigate whether these Russian producers were acquiring natural gas produced in Russia below cost levels. These two Russian ammonium nitrate producers are currently undergoing legal processes in which they are seeking to reduce the duty rates applied to their ammonium nitrate exports to the United States, and this decision by Commerce could possibly result in much lower duty rates in the near future. If the anti-dumping duty rates applied to the Russian AN producers were to be significantly lowered, we could likely face much higher volumes of Russian and Ukrainian fertilizer grade AN in the U.S. possibly priced below our current cost to produce fertilizer grade AN. In addition, producers in China have substantial capacity to produce and export urea. Depending on various factors, including prevailing prices from other exporters, the price of coal, and the price of China’s export tariff, higher volumes of urea from China could be imported into the U.S. at prices that have and could have an adverse effect on the selling prices of other nitrogen products, including the nitrogen products we manufacture and sell.

We may have inadequate insurance.

While we maintain liability, property and business interruption insurance, including certain coverage for environmental contamination, it is subject to coverage limits and policies may exclude coverage for some types of damages (which may include warranty claims). Although there may currently be sources from which such coverage may be obtained, it may not continue to be available to us on commercially reasonable terms or the possible types of liabilities that may be incurred by us may not be covered by our insurance. In addition, our insurance carriers may not be able to meet their obligations under the policies or the dollar amount of the liabilities may exceed our policy limits. Even a partially uninsured claim, if successful and of significant magnitude, could have a material adverse effect on our business, results of operations, financial condition and liquidity.

LSB is a holding company and depends, in large part, on receiving funds from its subsidiaries to fund our indebtedness.

Because LSB is a holding company and operations are conducted through its subsidiaries, LSB’s ability to meet its obligations depends, in large part, on the operating performance and cash flows of its subsidiaries and the ability of its subsidiaries to make distributions and pay dividends to LSB.

Our substantial level of indebtedness could limit our financial and operating activities, and adversely affect our ability to incur additional debt to fund future needs.

We currently have a substantial amount of indebtedness. As a result, this level of indebtedness could, among other things:

| • |  | require us to dedicate a substantial portion of our cash flow to the payment of principal and interest, thereby reducing the funds available for operations and future business opportunities;

| • |  | make it more difficult for us to satisfy our obligations, including our repurchase obligations;

| • |  | limit our ability to borrow additional money if needed for other purposes, including working capital, capital expenditures, debt service requirements, acquisitions and general corporate or other purposes, on satisfactory terms or at all;

| • |  | limit our ability to adjust to changing economic, business and competitive conditions;

| • |  | place us at a competitive disadvantage with competitors who may have less indebtedness or greater access to financing;

| • |  | make us more vulnerable to an increase in interest rates, a downturn in our operating performance or a decline in general economic conditions; and

| • |  | make us more susceptible to changes in credit ratings, which could impact our ability to obtain financing in the future and increase the cost of such financing.

Any of the foregoing could adversely impact our operating results, financial condition, and liquidity.

Loss of key personnel could negatively affect our business.

We believe that our performance has been and will continue to be dependent upon the efforts of our principal executive officers. We cannot promise that our principal executive officers will continue to be available. Jack E. Golsen has an employment agreement with us. No other principal executive has an employment agreement with us. The loss of some of our principal executive officers could have a material adverse effect on us. We believe that our future success will depend in large part on our continued ability to attract and retain highly skilled and qualified personnel.

Terrorist attacks and other acts of violence or war, and natural disasters (such as hurricanes, pandemic health crisis, etc.), have negatively impacted and could negatively impact U.S. and foreign companies, the financial markets, the industries where we operate, our operations and profitability.

Terrorist attacks and natural disasters (such as hurricanes) have in the past negatively impacted, and can in the future negatively affect our operations. We cannot predict further terrorist attacks and natural disasters in the U.S. and elsewhere. These attacks or natural disasters have contributed to economic instability in the U.S. and elsewhere, and further acts of terrorism, violence, war or natural disasters could further affect the industries where we operate, our ability to purchase raw

17

##### Table of Contents

materials, our business, results of operations and financial condition. In addition, terrorist attacks and natural disasters may directly impact our physical facilities, especially our chemical facilities, or those of our suppliers or customers and could impact our sales, our production capability and our ability to deliver products to our customers. In the past, hurricanes affecting the Gulf Coast of the U.S. have negatively impacted our operations and those of our customers. The consequences of any terrorist attacks or hostilities or natural disasters are unpredictable, and we may not be able to foresee events that could have an adverse effect on our operations.

We are currently effectively controlled by the Golsen Group

Jack E. Golsen, our Chairman of the Board of Directors (the “Board of Directors”) and Chief Executive Officer (“CEO”), members of his immediate family, including Barry H. Golsen, our Vice Chairman and President, entities owned by them and trusts for which they possess voting or dispositive power as trustee (collectively, the “Golsen Group”) owned as of February 14, 2014, an aggregate of 2,916,464 shares of our common stock and 1,020,000 shares of our voting preferred stock (1,000,000 of which shares have .875 votes per share, or 875,000 votes), which together votes as a class and represents approximately 16% of the voting power (prior to conversion of the shares of voting preferred) of our issued and outstanding voting securities as of that date. The series of preferred represented by the 20,000 shares of voting preferred is convertible into an aggregate of 666,666 shares of our common stock. Thus, the Golsen Group may be considered to effectively control us. As a result, the ability of other stockholders to influence our management and policies could be limited.

Our business could be negatively affected as a result of a proxy contest.

We have received certain proposals as to our business and notice that there may be a slate of directors proposed in opposition to the three directors that are up for election at our 2014 Annual Meeting of Shareholders and that would be nominated by our Board of Directors. Our business, operating results, liquidity or financial condition have been and could continue to be adversely affected by the proposals and a potential proxy contest because, among other things:

| • |  | considering and responding to the proposals and a potential proxy contest has been, and may continue to be, disruptive, costly and time consuming and a significant distraction for our management;

| • |  | perceived uncertainties as to our future may result in the loss of current customers and potential business opportunities and may make it more difficult to attract and retain qualified personnel;

| • |  | it may adversely affect our ability to create additional value for our stockholders by effectively limiting the implementation of our business strategy; and

| • |  | future trading prices of our common stock could be affected by public statements and other actions in a proxy contest, which we cannot predict or control.

We have not paid dividends on our outstanding common stock in many years.

Although we have paid dividends on our outstanding series of preferred stock (two of the three outstanding series of preferred stock are owned by the Golsen Group), in the past we have not paid cash dividends on our outstanding common stock in many years, and we do not currently anticipate paying cash dividends on our outstanding common stock in the near future. However, our Board of Directors has not made a decision whether or not to pay such dividends on our common stock in 2014. In addition, there are certain limitations contained in our loan agreements, which limit our subsidiaries from up streaming funds to LSB that may limit our ability to pay dividends on our outstanding common stock.

Future issuance or potential issuance of our common stock could adversely affect the price of our common stock, our ability to raise funds in new stock offerings and could dilute the percentage ownership of our common stockholders.

Future sales of substantial amounts of our common stock or equity-related securities in the public market, or the issuance of a substantial amount of our common stock as the result of conversion of our outstanding convertible preferred stocks, or the perception that such sales or conversions could occur, could adversely affect prevailing trading prices of our common stock and could dilute the value of common stock held by our existing stockholders. No prediction can be made as to the effect, if any, that future sales of, or conversions of our outstanding preferred stocks into, shares of common stock or the availability of shares of common stock for future sale will have on the trading price of our common stock. Such future sales or conversions could also significantly reduce the percentage ownership of our common stockholders.

We are subject to a variety of factors that could discourage other parties from attempting to acquire us.

Our certificate of incorporation provides for a staggered Board of Directors and, except in limited circumstances, a two-thirds vote of outstanding voting shares to approve a merger, consolidation or sale of all, or substantially all, of our assets. In addition, we have entered into severance agreements with our executive officers and some of the executive officers of certain subsidiaries that provide, among other things, that if, within a specified period of time after the occurrence of a change in control of LSB, these officers are terminated, other than for cause, or the officer terminates his employment for good reason, we must pay such officer an amount equal to 2.9 times the officer’s average annual gross salary for the last five years preceding the change in control.

We have authorized and unissued (including shares held in treasury) 52,473,992 shares of common stock and 4,230,000 shares of preferred stock as of December 31, 2013. These unissued shares could be used by our management to make it more difficult, and thereby discourage an attempt to acquire control of us.

We have adopted a preferred share purchase plan, which is designed to protect us against certain creeping acquisitions, open market purchases and certain mergers and other combinations with acquiring companies.

The foregoing provisions and agreements are designed to discourage a third party tender offer, proxy contest, or other attempts to acquire control of us and could have the effect of making it more difficult to remove incumbent management.

Delaware has adopted an anti-takeover law which, among other things, will delay for three years business combinations with acquirers of 15% or more of the outstanding voting stock of publicly-held companies (such as us), unless:

| • |  | prior to such time the Board of Directors of the corporation approved the business combination that results in the stockholder becoming an invested stockholder;

| • |  | the acquirer owned at least 85% of the outstanding voting stock of such company prior to commencement of the transaction;

| • |  | two-thirds of the stockholders, other than the acquirer, vote to approve the business combination after approval thereof by the Board of Directors; or

| • |  | the stockholders of the corporation amend its articles of incorporation or by-laws electing not to be governed by this provision

ITEM 2. PROPERTIES

Chemical Business

Our Chemical Business primarily conducts manufacturing operations in facilities located:

| • |  | on 150 acres of a 1,400 acre tract of land in El Dorado, Arkansas,

| • |  | on 160 acres of a 1,300 acre tract of land in Cherokee, Alabama,

| • |  | on 47 acres of a 104 acre tract of land within an industrial park in Pryor, Oklahoma and

| • |  | on property within Bayer’s manufacturing complex in Baytown, Texas.

We own all of these manufacturing facilities except the Baytown Facility. Except for certain assets that are owned by EDN for use in the production process within the Baytown Facility, the Baytown Facility is owned by Bayer. EDN operates and maintains the Baytown Facility pursuant to the Bayer Agreement.

As of December 31, 2013, our Chemical Business distributes its agricultural products through 11 wholesale and retail distribution centers, with 9 of the centers located in Texas (8 of which we own and 1 of which we lease); 1 center located in Tennessee (owned); and 1 center located in Missouri (owned).

19

##### Table of Contents

Most of our real property and equipment located at our chemical facilities are being used to secure our long-term debt. All of the properties utilized by our Chemical Business are suitable and adequate to meet the current needs of that business.

For 2013, the following was our percentage of utilization based on continuous operation, which is adjusted for downtime for planned major maintenance activities (“Turnarounds”).

|  | Percentage of Capacity |
El Dorado Facility (1) |  |  | 56 | %
Cherokee Facility (2) |  |  | 67 | %
Pryor Facility (3) |  |  | 43 | %
Baytown Facility |  |  | 90 | %

(1) | The percentage of capacity for the El Dorado Facility relates to its nitric acid capacity, which total capacity has been reduced as the result of the explosion of a nitric acid plant in 2012. The capacity utilization rate is negatively affected by the reduction in mining product tons produced. The El Dorado Facility has capacity to produce other nitrogen products in excess of its nitric acid capacity.

(2) | The percentage of capacity for the Cherokee Facility relates to its ammonia production capacity. The Cherokee Facility is able to purchase anhydrous ammonia by truck, rail or barge to supplement its ammonia production capacity. The low percentage of utilization is the direct result of the unplanned downtime during 2013.

(3) | The percentage of capacity for the Pryor Facility relates to current operating ammonia production capacity estimated at 600 tons per day and 330 days of production per year. The Pryor Facility has additional operational capacity for nitric acid and AN solution in excess of its current ammonia capacity. The low percentage of utilization is the direct result of the unplanned downtime during 2013.

Climate Control Business

Our Climate Control Business conducts its operations in seven facilities, all located in the greater Oklahoma City, Oklahoma area, totaling approximately 1 million square feet including the following:

Our Climate Control Business manufactures most of its geothermal and water source heat pump products in owned facilities totaling approximately 440,000 square feet. For 2013, we utilized approximately 79% of the production capacity of this manufacturing facility, based primarily on two ten-hour shifts per day and a four-day workweek and current staffing levels. Capacity could be increased within the confines of the existing facilities through additional staffing, the scheduling of supplemental shifts, and the purchase of more machinery and equipment. We also utilize approximately 126,000 square feet of an owned facility for a distribution center.

Our Climate Control Business conducts its fan coil manufacturing operation in facilities totaling approximately 230,000 square feet. We own a majority of these facilities. For 2013, our fan coil manufacturing operation utilized approximately 56% of the production capacity, based primarily on one ten-hour shift per day and a four-day workweek and current staffing levels. Capacity could be increased within the confines of the existing facilities through additional staffing, the scheduling of supplemental shifts, and the purchase of more machinery and equipment.

Our Climate Control Business conducts its large air handler manufacturing operation in an owned facility consisting of approximately 120,000 square feet. For 2013, we utilized approximately 46% of the production capacity of this manufacturing facility, based primarily on one eight-hour shift and a five-day workweek and a partial second shift in selected areas.

Our Climate Control Business conducts its modular chiller manufacturing operation in an area consisting of approximately 70,000 square feet within an owned facility. For 2013, we utilized approximately 39% of the production capacity of this manufacturing facility, based primarily on one ten-hour shift and a four-day workweek and current staffing levels. Capacity could be increased within the confines of the existing facilities through additional staffing, the scheduling of supplemental shifts, and the purchase of more machinery and equipment.

##### Table of Contents

Capacity of the Climate Control Business can also be increased within the confines of the existing facilities by achieving certain operational efficiencies through LSB’s LEAN Operational Excellence initiative.

Most of our real property and equipment located at our Climate Control facilities have been mortgaged to secure the Senior Secured Notes. All of the properties utilized by our Climate Control Business are suitable to meet the current needs of that business.

West Fertilizer

During April 2013, an explosion and fire occurred at the West Fertilizer Co. (“West Fertilizer”), located in West, Texas, causing death, bodily injury and substantial property damage. West Fertilizer is not owned or controlled by us, but West Fertilizer had been a customer of EDC, purchasing ammonium nitrate (“AN”) from EDC from time to time. LSB and EDC previously received letters from counsel purporting to represent subrogated insurance carriers, personal injury claimants and persons who suffered property damages informing them that their clients are conducting investigations into the cause of the explosion and fire to determine, among other things, whether AN manufactured by EDC and supplied to West Fertilizer was stored at West Fertilizer at the time of the explosion and, if so, whether such AN may have been one of the contributing factors of the explosion. Other manufacturers of AN also supplied AN to West Fertilizer. Initially, the lawsuits that had been filed named West Fertilizer and another supplier of AN as defendants. Although EDC does not believe that its product was in storage at West Fertilizer at the time of the explosion, there has been testimony in dispositions taken in connection with the pending lawsuits that some of the AN products at West Fertilizer at time of the explosion were produced by EDC. As a result, EDC and LSB have been named as defendants, together with other AN manufactures, in the case styled City of West, Texas v CF Industries, Inc., et al, in the District Court of McLennan County, Texas. Plaintiffs are alleging, among other things, that LSB and EDC were negligent in the production and inspection of fertilized products sold to West Fertilizer resulting in death, personal injury and property damage. EDC has retained a firm specializing in cause and origin investigations, with particular experience with fertilizer facilities, to assist EDC in its own investigation. LSB and EDC have placed its liability insurance carrier on notice of this matter. Our product liability insurance policies have aggregate limits of general liability totaling $100 million, with a self-insured retention of $250,000. As of December 31, 2013, no liability has been established in connection with this matter, but we have incurred professional fees of approximately $200,000 being applied against our self-insured retention amount.

Other Claims and Legal Actions

We are also involved in various other claims and legal actions including claims for damages resulting from water leaks related to our Climate Control products and other product liability occurrences. Most of the product liability claims are covered by our general liability insurance, which generally includes a deductible of $250,000 per claim. For any claims or legal actions that we have assessed the likelihood of our liability as probable, we have recognized our estimated liability up to the applicable deductible. At December 31, 2013, our accrued general liability insurance claims were $335,000 and are included in accrued and other liabilities. It is possible that the actual future development of claims could be different from our estimates but, after consultation with legal counsel, we believe that changes in our estimates will not have a material effect on our business, financial condition, results of operations or cash flows.

##### Table of Contents

Sale of Unregistered Securities

There were no unregistered sales of equity securities in 2013 that have not been previously reported in a Quarterly Report on Form 10-Q or Current Report on Form 8-K.

Purchases of Equity Securities by the Issuer and Affiliated Purchasers

During the three months ended December 2013, there were no purchases of equity securities by the Company and affiliated purchasers.

Preferred Share Rights Plan

We have adopted a preferred share rights plan to protect us against certain creeping acquisitions, open market purchases and certain mergers and other combinations with acquiring companies. The rights plan will impact a potential acquirer unless the acquirer negotiates with our Board of Directors and the Board of Directors approves the transaction. Pursuant to the rights plan, one preferred share purchase right (a “Right”) is attached to each currently outstanding or subsequently issued share of our common stock. Prior to becoming exercisable, the Rights trade together with our common stock. In general, if a person or group acquires or announces a tender or exchange offer for 15% or more of our common stock (except for the Golsen Group and certain other limited excluded persons), then the Rights become exercisable. Each Right entitles the holder (other than the person or group that triggers the Rights being exercisable) to purchase from us one one-hundredth of a share of Series 4 Junior Participating Preferred Stock, no par value (the “Preferred Stock”), at an exercise price of $47.75 per one one-hundredth of a share, subject to adjustment. If a person or group acquires 15% or more of our common stock, each Right will entitle the holder (other than the person or group that triggered the Rights being exercisable) to purchase shares of our common stock (or, in certain circumstances, cash or other securities) having a market value of twice the exercise price of a Right at such time. Under certain circumstances, each Right will entitle the holder (other than the person or group that triggered the Rights being exercisable) to purchase the common stock of the acquirer having a market value of twice the exercise price of a Right at such time. In addition, under certain circumstances, our Board of Directors may exchange each Right (other than those held by the acquirer) for one share of our common stock, subject to adjustment. Our Board of Directors may redeem the Rights at a price of $0.01 per Right generally at any time before 10 days after the Rights become exercisable. Our Board of Directors may exchange all or part of the Rights (except to the person or group that triggered the Rights being exercisable) for our common stock at an exchange ratio of one common share per Right until the person triggering the Right becomes the beneficial owner of 50% or more of our common stock.

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

The following Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”) should be read in conjunction with a review of the other Items included in this Form 10-K and our December 31, 2013 Consolidated Financial Statements included elsewhere in this report. Certain statements contained in this MD&A may be deemed to be forward-looking statements. See “Special Note Regarding Forward-Looking Statements.”

Overview

General

LSB is a manufacturing and marketing company operating through our subsidiaries. LSB and its wholly-owned subsidiaries own the following core businesses:

| • |  | Chemical Business manufactures and sells nitrogen-based chemical products produced from four facilities located in El Dorado, Arkansas; Cherokee, Alabama; Pryor, Oklahoma; and Baytown, Texas for the agricultural, industrial and mining markets. Our products include high purity and commercial grade anhydrous ammonia for industrial and agricultural applications, industrial and fertilizer grade AN, UAN, sulfuric acids, nitric acids in various concentrations, nitrogen solutions, DEF and various other products. For 2013, approximately 56% of our consolidated net sales relates to the Chemical Business compared to 63% for 2012.

| • |  | Climate Control Business manufactures and sells a broad range of HVAC products in the niche markets we serve consisting of geothermal and water source heat pumps, hydronic fan coils, large custom air handlers, modular geothermal and other chillers and other related products used to control the environment in commercial/institutional and residential new building construction, renovation of existing buildings and replacement of existing systems. Our Climate Control Business manufactures and distributes its products from seven facilities located in Oklahoma City, Oklahoma. For 2013, approximately 42% of our consolidated net sales relates to the Climate Control Business compared to 35% for 2012.

Issuance of Senior Secured Notes, Intended Use of Proceeds and Amended Working Capital Revolver Loan

On August 7, 2013, LSB sold $425 million aggregate principal amount of the 7.75% Senior Secured Notes due 2019 (the “Senior Secured Notes”) in a private placement.

LSB has used, or intends to use, the proceeds, net of commissions and fees, from the sale of the Senior Secured Notes, as follows:

| • |  | $67.2 million was used to pay all outstanding borrowings, including the prepayment penalty, under a term loan agreement (the “Secured Term Loan”);

| • |  | in connection with the construction and completion of the new ammonia plant at the El Dorado Facility, which when completed, we believe will significantly decrease our cost and exposure to fluctuations in the price of ammonia in the spot market;

| • |  | in connection with the construction of the 65% nitric acid plant and concentrator also at the El Dorado Facility, which, when completed, will replace lost capacity and add additional capacity to facilitation growth;

| • |  | to improve plant reliability and environmental and safety upgrades at our chemical facilities; and

| • |  | for the development of our natural gas working interest leasehold, which we believe will provide a partial hedge for our cost of natural gas, one of the key raw material imports.

Pending application of proceeds discussed above, the net proceeds from the Senior Secured Notes are currently invested in highly rated money market funds, certificates of deposit and U.S. Treasury bills.

The Senior Secured Notes are jointly and severally and fully and unconditionally guaranteed by all of LSB’s subsidiaries and are collateralized with a substantial portion of LSB and most of its subsidiaries’ assets.

##### Table of Contents

On February 13, 2014, LSB entered into an Amended and Restated Loan Agreement, effective as of December 31, 2013, providing for a revolving line of credit up to $100 million subject to eligible collateral.

See further discussion relating to the Senior Secured Notes and the amended Working Capital Revolver Loan below under “Loan Agreements – Terms and Condition” of this MD&A.

Economic Conditions

Since our two core business segments serve several diverse markets, we consider fundamentals for each market individually as we evaluate economic conditions. From a macro standpoint, we believe the U.S. economy is poised for modest growth, based upon certain economic reports, including the Conference Board Composite Index of Leading Indicators.

Chemical Business—Our Chemical Business’ primary markets are agricultural, industrial and mining. During 2013, sales were $381 million or 20% lower than 2012. Due to the significant downtime at certain of our chemical facilities, as discussed below under “Downtime at Certain Chemical Facilities and Related Programs,” production and sales (in volumes and dollars) were lower in all three of our primary markets compared to the same period in 2012.

In normal circumstances, our agricultural sales volumes and prices depend upon the supply of and the demand for fertilizer, which in turn depends on the market fundamentals for crops including corn, wheat, cotton and forage. Although currently showing strength, nitrogen fertilizer prices are lower than the same time a year ago due in part to the significant increase in urea imports from China earlier during 2013. In addition, there was a significant increase in the 2013-2014 corn harvest and much lower forward corn prices as compared to a year ago. According to the USDA’s World Agricultural Supply and Demand Estimates, the U.S. yield per harvested acre of corn increased significantly from approximately 123 bushels per acre to 158 bushels per acre and the year end corn stocks were approximately double a year ago, resulting in a significant increase in the stock-to-use ratio. Notwithstanding the current conditions, the fundamentals continue to be positive for nitrogen fertilizer products we produce and sell and gross margins, although lower, are still strong. However, the fertilizer outlook could change if there are unanticipated changes in domestic fertilizer production capacity, acres planted of crops requiring fertilizer, unfavorable weather conditions or continued low selling prices and increases in imported urea from China. Our industrial acids sales volume is dependent upon general economic conditions primarily in the housing, automotive, and paper industries. According to the American Chemical Council, the outlook for these three sectors is generally positive. Our sales prices vary with the market price of our feedstock cost of ammonia or sulfur as applicable in our pricing arrangements with customers. Our mining sales volume is being impacted by lower customer demand for industrial grade AN, which we believe is primarily due to natural gas being a more attractive alternative feedstock than coal for utility companies. As reported by the U.S. Energy Information Administration, during 2013, coal production was down overall by 1.5%, although coal inventories declined by 43 million tons during the period. With such inventory decreases, the coal industry is now expected to see production growth of 3% to 4% in 2014 as inventories stabilize and short-term natural gas prices increase.

We use natural gas to produce anhydrous ammonia in two of our four facilities, in which ammonia is used to produce nitrogen fertilizer and industrial products, and sold in its original form. We also produce agricultural grade and industrial grade AN from purchased ammonia, which current cost is significantly higher than producing it from natural gas, resulting in a cost disadvantage compared to nitrogen fertilizers and industrial AN producers that manufacture from natural gas. Using a portion of the net proceeds from the sale of the Senior Secured Notes as discussed above under “Issuance of Senior Secured Notes, Intended Use of Proceeds and Amended Working Capital Revolver Loan”, and working capital, we are proceeding with the design, fabrication, engineering and construction of an ammonia plant at the El Dorado Facility in order to eliminate this current cost disadvantage.

Climate Control Business—Sales for 2013 were $285 million, or 7% higher than 2012, including a 16% increase in hydronic fan coil sales and a 13% increase in geothermal and water source heat pump sales (both increases were associated with a higher number of units shipped, unit pricing and product mix) partially offset by a 23% decrease in other HVAC sales, primarily in sales of our large custom air handlers. From a market sector perspective, the sales increase was due to an 8% improvement in commercial/institutional product sales, and a 3% improvement in residential product sales. The improvement in commercial/institutional and residential sales in 2013 is primarily due to higher new construction activity in those sectors, which resulted in higher customer order intake in the preceding periods for our commercial/institutional products in most of our product lines. For 2013, order levels of our products decreased 2% in both residential products and commercial/institutional products. Information available from the McGraw-Hill Construction Market forecast indicates that construction activity for the markets we serve in the commercial/institutional and single-family residential sectors are expected to increase in aggregate during 2014 although still significantly below pre-recession levels.

2013 Results

Our consolidated net sales for 2013 were $679 million, a decrease of $80 million compared to 2012. The sales decrease included a decrease of $97 million in our Chemical Business partially offset by an increase of $19 million in our Climate Control Business as discussed in more detail below.

Our consolidated operating income was $105 million for 2013, including $94.6 million business interruption and property damage insurance recoveries, compared to $96 million in 2012 which included $7.3 million insurance recoveries. Excluding insurance recoveries, our Chemical Business operating income decreased $82 million and our Climate Control Business increased $5 million, as discussed in more detail below.

Our resulting effective income tax rate for 2013 was 39% compared to 36% for 2012.

Chemical Business

Our Chemical Business operates four chemical facilities. The Cherokee and Pryor Facilities produce anhydrous ammonia and nitrogen products from natural gas delivered by pipeline but can also receive supplemental anhydrous ammonia by other modes of delivery. The El Dorado and Baytown Facilities produce nitrogen products from anhydrous ammonia delivered by pipeline.

Our Chemical Business sales for 2013 were $381 million, a decrease of $97 million compared to 2012, which includes a $50 million decrease in agricultural products sales, a $21 million decrease in industrial acids and other products sales, and a $33 million decrease in mining products sales.

The percentage change in sales (volume and dollars) for 2013 compared to 2012 is as follows (excluding natural gas sales):

|  | Percentage Change of |
|  | Tons |  |  | Dollars |
Chemical products: |  |  |  |  |  |  |  |
Agricultural |  |  | (12 | )% |  |  | (23 | )%
Industrial acids and other |  |  | (6 | )% |  |  | (13 | )%
Mining |  |  | (44 | )% |  |  | (35 | )%
Total weighted-average change |  |  | (15 | )% |  |  | (22 | )%

The decrease in agricultural sales was due to the lack of available products as the result of unplanned downtime at our facilities, lower sales prices, and periodic adverse weather conditions during 2013.

The decrease in industrial acids and other sales was primarily due to lower sales prices as a result of pass through of raw material costs provisions (primarily ammonia) included in contractual pricing agreements with certain of our customers.

The decrease in mining sales was primarily due to lower demand for coal due to natural gas being a more attractive alternative feedstock than coal for utility companies and the downtime experienced at the Cherokee Facility.

Our primary raw material feedstocks (anhydrous ammonia and natural gas) are commodities subject to significant price fluctuations. Generally, we purchase at prices in effect at the time of delivery; however, periodically, we enter into contracts to purchase natural gas for anticipated production needs, which contract prices will vary from the spot market prices. In addition, our Chemical Business owns working interests in certain natural gas properties. Management considers these working interests as a partial economic hedge against a potential rise in natural gas prices in the future. During 2013, the average prices for those commodities compared to 2012 were as follows:

28

##### Table of Contents

|  | 2013 |  |  | 2012 |
Natural gas average price per MMBtu based upon Henry Hub pipeline pricing point |  | $ | 3.72 |  |  | $ | 2.75 |
Ammonia average price based upon low Tampa price per metric ton |  | $ | 543 |  |  | $ | 600 |

Most of our Chemical Business sales in the industrial and mining markets were pursuant to sales contracts and/or pricing arrangements on terms that include the cost of raw material feedstock as a pass through component in the sales price. Our Chemical Business sales in the agricultural markets primarily were at the spot market price in effect at the time of sale or at a negotiated future price.

The Chemical Business’ operating income for 2013 was $87.8 million compared to $82.1 million for 2012. The increase in operating income was due to insurance recoveries of $94.6 million recognized in 2013 (compared to $7.3 million in 2012) offset by lower selling prices for nitrogen fertilizers, lower sales volumes due to the impact of unplanned downtime at certain of our Chemical facilities and higher natural gas costs. See additional discussions below under “Property and Business Interruption Insurance Claims and Recoveries” and “Downtime at Certain Chemical Facilities and Related Programs.”

The following table shows the estimated range of the adverse effect on operating income by facility resulting from the lost productions due to the downtime related to these issues offset by insurance recoveries:

|  | 2013 |
|  | (Estimated Range) |
|  | Low |  |  | High |
|  | (In Millions) |
Estimated adverse effect by facility: |  |  |  |  |  |  |  |
El Dorado |  | $ | 10.0 |  |  | $ | 12.0 |
Cherokee |  |  | 30.6 |  |  |  | 35.6 |
Pryor |  |  | 64.0 |  |  |  | 73.0 |
Total estimated adverse effect |  |  | 104.6 |  |  |  | 120.6 |
Insurance recoveries |  |  | (94.6 | ) |  |  | (94.6 | )
Total estimated effect, net of insurance recoveries |  | $ | 10.0 |  |  | $ | 26.0 |

The estimated adverse effect shown above includes lost absorption and gross profit margins, based on current market conditions, and additional expenses incurred.

Pursuant to a long-term cost-plus supply agreement, EDC sells to a customer a significant annual volume of industrial grade AN produced at the El Dorado Facility. In April 2013, this agreement was amended to update and correct the specification of AN solution to be manufactured by EDC. The amendment also modified the required notice of termination from two years to one year, with the effective termination date in such notice to be no sooner than April 9, 2015.

During 2013, the ADEQ issued an air permit for the new 65% strength nitric acid plant, the new 98% concentrator, the new ammonia plant, and the associated infrastructure. Obtaining the air permit was a key requirement before construction activities could commence on these projects, which construction began during the fourth quarter of 2013.

Climate Control Business

Our Climate Control sales for 2013 were $285 million, or approximately $19 million higher than 2012, and included an approximate $21 million increase in geothermal and water source heat pump sales, a $9 million increase in hydronic fan coil sales partially offset by a $11 million decrease in other HVAC sales, primarily due to a reduction in sales of our custom air handler products. We do not believe the decline in our other HVAC sales to be indicative of a trend. From a market sector perspective, the increase included a $17 million improvement in commercial/institutional product sales and a $2 million improvement in residential product sales.

We continue to follow economic indicators and monitor their the impact on the commercial/institutional and residential construction sectors that we serve, including, but not limited to, new construction and/or renovation of facilities in the following sectors:

| • |  | Education

| • |  | Single-Family Residential

| • |  | Multi-Family Residential

| • |  | Hospitality

| • |  | Healthcare

| • |  | Retail

| • |  | Government

During 2013, approximately 83% of our Climate Control Business’ sales were to the commercial/institutional and multi-family construction markets, and the remaining 17% were sales of geothermal heat pumps (“GHPs”) to the single-family residential market.

(1) | Our product order level consists of confirmed purchase orders from customers that have been accepted and received credit approval. Our backlog consists of confirmed customer orders for product to be shipped at a future date. Historically, we have not experienced significant cancellations relating to our backlog of confirmed customer product orders, and we expect to ship substantially all of these orders within the next twelve months; however, it is possible that some of our customers could cancel a portion of our backlog or extend the shipment terms. Product orders and backlog, as reported, generally do not include amounts relating to shipping and handling charges, service orders or service contract orders. In addition, product orders and backlog, as reported, exclude contracts related to our construction business due to the relative size of individual projects and, in some cases, extended timeframe for completion beyond a twelve-month period.

For January 2014, our new orders received were approximately $20 million and our backlog was approximately $39 million at January 31, 2014.

Our GHPs use a form of renewable energy and, under certain conditions, we believe can reduce energy costs up to 80% compared to some conventional HVAC systems. Tax legislation continues to provide incentives for customers purchasing products using forms of renewable energy and is effective through December 31, 2016.

We expect the Climate Control Business to experience moderate sales growth in the short-term compared to 2013. Although a significant part of the Climate Control Business’ sales are products that are used for renovation and replacement applications, sales increases in the medium-term and long-term are expected to be primarily driven by growth in new construction, as well as the introduction of new products. We continue to focus our sales and marketing efforts to increase our share of the existing market for our products as well as expand the market for and application of our products, including GHPs.

As previously reported, in November 2013, Carrier Corporation (“Carrier”) advised one of our subsidiaries, Climate Master, Inc. (“CM”), that the heat pump contracts will not be renewed between CM, as the manufacturer, and Carrier, as the purchaser, effective May 11, 2014. During 2013, 2012 and 2011, net sales pursuant to these heat pump contracts represented less than 5% of LSB’s consolidated net sales during each of those periods.

Potential Proxy Contest

We have received certain proposals as to our business and notice that there may be a slate of directors proposed in opposition to the three directors that are up for election at our 2014 Annual Meeting of Shareholders and that would be nominated by our Board of Directors. Our business, operating results, liquidity or financial condition have been and could continue to be adversely affected by the proposals and a potential proxy contest because, among other things:

| • |  | considering and responding to the proposals and a potential proxy contest has been, and may continue to be, disruptive, costly and time consuming and a significant distraction for our management;

| • |  | perceived uncertainties as to our future may result in the loss of current customers and potential business opportunities and may make it more difficult to attract and retain qualified personnel;

| • |  | it may adversely affect our ability to create additional value for our stockholders by effectively limiting the implementation of our business strategy.

Downtime at Certain Chemical Facilities and Related Programs

During 2012, 2013 and the first quarter of 2014, our Chemical Business encountered a number of significant issues. These issues included an explosion in one of our nitric acid plants at the El Dorado Facility in May 2012, a pipe rupture at the Cherokee Facility in November 2012 that damaged the ammonia plant, and the suspension of production at the Pryor Facility from time to time during 2012, 2013 and into the first quarter of 2014 due to continued mechanical issues. All of these issues resulted in lost production causing an adverse effect on our sales, operating income and cash flow for 2012 and 2013 and the first quarter of 2014. The following table shows the estimated range of the adverse effect on operating income by facility resulting from the lost productions due to the downtime related to these issues offset by insurance recoveries:

|  | 2013 |
|  | (Estimated Range) |
|  | Low |  |  | High |
|  | (In Millions) |
Estimated adverse effect by facility: |  |  |  |  |  |  |  |
El Dorado |  | $ | 10.0 |  |  | $ | 12.0 |
Cherokee |  |  | 30.6 |  |  |  | 35.6 |
Pryor |  |  | 64.0 |  |  |  | 73.0 |
Total estimated adverse effect |  |  | 104.6 |  |  |  | 120.6 |
Insurance recoveries |  |  | (94.6 | ) |  |  | (94.6 | )
Total estimated effect, net of insurance recoveries |  | $ | 10.0 |  |  | $ | 26.0 |

The estimated adverse effect shown above includes lost absorption and gross profit margins, based on current market conditions, and additional expenses incurred.

Although we believe these issues are unrelated to each other, the severity and frequency of the events at our Pryor, Cherokee, and El Dorado Facilities caused us to undergo a thorough reexamination of our process safety management (“PSM”), reliability and mechanical integrity programs. As a result, we have undertaken a concerted program to attempt to improve the reliability and mechanical integrity of our chemical plant facilities, which program is expected to take several years to complete. The improvement program includes engaging outside experts and consultants who specialize in risk management, reliability, mechanical integrity and PSM. We are also recruiting and hiring additional corporate and plant engineering and operational personnel, and accelerating acquisition of additional spare parts to supplement our existing spare parts program. For 2013, we incurred expenses of approximately $3.2 million in connection with this program and anticipates that we will incur additional expenses of $1.8 million during 2014 in connection with this program. The program also includes the installation of additional automation and improved diagnostics.

El Dorado Facility – During May, 2012, the El Dorado Facility suffered significant damage when a reactor in its DSN plant exploded. As a result, the DSN plant was damaged beyond repair and several other plants and infrastructure within the El Dorado Facility sustained various degrees of damage. The DSN plant, which supplied approximately 20% of the nitric acid produced at this facility, will be replaced with a new 65% strength nitric acid plant and a 98% concentrator. The design, fabrication, and engineering of the new nitric acid plant and concentrator are in process, and most equipment has been ordered.

We estimate that the monthly negative effect on operating income at the El Dorado Facility will approximate $1 million until the new 65% strength nitric acid plant and the 98% concentrator are constructed and begin production during 2015. The estimated combined construction cost for the new nitric acid plant and concentrator is approximately $120 million, of which $48 million has been capitalized as of December 31, 2013. Together, these new plants are designed to be more efficient and provide higher production capacity.

Cherokee Facility – During November, 2012, a pipe ruptured within the Cherokee Facility causing damage primarily to the heat exchanger portion of its ammonia plant. As a result of the damage, the Cherokee Facility could only produce, on a limited basis, nitric acid and AN solution from purchased ammonia until the repairs were completed that directly reduced our net sales and gross profit margins. The Cherokee Facility restarted in May 2013 and has been running consistently at normal production rates since resuming production during 2013, with normal interruptions for maintenance.

Pryor Facility – During November 2012, production was stopped at the primary ammonia plant to perform unplanned maintenance on a compressor. During this downtime, we also replaced the ammonia converter and restarted the primary ammonia plant in April 2013; however, after the facility resumed production, we have continued to experience frequent operational issues that have required extensive equipment repairs and maintenance and related costs. As a result, the Pryor Facility’s ammonia production during 2013 was only 42%, directly reducing our ammonia and UAN sales and gross profit margins.

During the first part of January 2014, our Pryor Facility ceased production at the ammonia plant to make repairs and perform additional maintenance. We estimate the adverse impact to our operating income will be approximately $8.0 million per month, including maintenance and repair costs, until the plant resumes production.

Property and Business Interruption Insurance Claims and Recoveries

El Dorado Facility

Our insurance covering the claim relating to the explosion of the DSN plant at the El Dorado Facility in May 2012, provided for repair or replacement cost coverage relating to property damage with a $1.0 million deductible and provided for business interruption coverage for certain lost profits and extra expense with a 30-day waiting period. We concluded that due to the extensive damage, the DSN plant should not be repaired but should be replaced with a new 65% strength nitric acid plant and a separate nitric acid concentrator.

In October 2013, we settled these claims with our insurance carriers for the aggregate amount of $113 million, of which $60 million had been paid to us prior to the conclusion of these claims and the remaining $53 million was paid to us during October and November of 2013. For financial reporting purposes, we allocated $90.7 million to our property insurance claim and $22.3 million to our business interruption claim primarily based on negotiations with our insurance carriers concerning our claims.

The $90.7 million allocated to the property insurance claim was partially applied against the recoverable costs totaling $24.7 million (primarily relating to the loss on disposal of the damaged property and certain repairs and clean-up costs incurred). The insurance recovery in excess of the recoverable costs of $66.0 million was recognized as property insurance recoveries in excess of losses incurred in 2013.

The insurance recovery of $22.3 million allocated to the business interruption claim was recognized as a reduction to cost of sales ($15.0 million in 2013 and $7.3 million in 2012) consisting of recoverable costs (primarily relating to additional expenses associated with purchased product sold to our customers while certain of our nitric and sulfuric acid plants were being repaired) and certain lost profits.

Cherokee Facility

Our insurance policy covering the claim related to the pipe rupture that damaged the ammonia plant at the Cherokee Facility in November 2012, provided for repair or replacement cost coverage relating to property damage with a $2.5 million deductible and provided for business interruption coverage for certain lost profits and extra expense with a 30-day waiting period. As a result of this event, a notice of insurance claims for property damage and business interruption was filed with the insurance carriers, which insurance claims were settled with our insurance carriers in January 2014 as discussed below.

As of December 31, 2013, our insurance carriers approved and funded advance payments relating to our business interruption claim totaling $15 million. We received correspondence associated with the approval of these payments, which stated that our insurance carriers are still investigating the circumstances surrounding this event (including the cause of this event, scope of our losses and support for our claim) under a reservation of rights.

##### Table of Contents

The business interruption insurance recovery of $15 million was applied against recoverable costs (primarily relating to additional expenses associated with purchased product sold or used in products sold to our customers while our facility was being repaired) totaling $13.6 million as a reduction to cost of sales in 2013. The insurance recovery in excess of recoverable costs of $1.4 million was deferred (included in deferred gain on insurance recoveries at December 31, 2013) since this amount relates to lost profits, which is considered a gain contingency.

As of December 31, 2013, the balance of the insurance claim receivable, included in accounts receivable, relating to this event was $1.9 million, consisting of recoverable costs associated with our property insurance claim.

Effective January 10, 2014, we settled the claim with our insurance carriers for the aggregate amount of approximately $43.5 million (of which approximately $36.5 million relates to the business interruption claim), comprised of $15 million previously paid to us and $28.5 million paid to us in January 2014. The $43.5 million settlement amount is net of our $2.5 million property insurance deductible. As a result, an insurance recovery of approximately $28 million will be recognized as income associated with this settlement in the first quarter of 2014.

Due to the increase in the total value of property, plant and equipment (“PP&E”) and the insurance claims discussed above relating to our Chemical Business, our insurance premiums have increased (a portion of which was financed through short-term financing agreements) and are expected to increase in future periods.

For 2014 and 2015, we have extensive committed and planned capital expenditures. Our primary cash needs for this period of time will be to fund these capital expenditures, as well as, our operations, our general obligations, and our interest payment requirements. We expect to fund these cash needs from the noncurrent restricted cash and investments (provided from the proceeds from the Senior Secured Notes), working capital, internally generated cash flows, insurance proceeds, and third-party financing. See additional discussions below under “Capital Expenditures” and “Loan Agreements-Terms and Conditions.” Our internally generated cash flows and liquidity have been, and could be, affected by possible declines in sales volumes resulting from the uncertainty relative to the current economic conditions and production inefficiency of our facilities.

As discussed above under “Issuance of Senior Secured Notes and Intended Use of Proceeds” and below under “Loan Agreements-Terms and Conditions,” on August 7, 2013, LSB closed the transaction whereby LSB sold $425 million aggregate principal amount of the Senior Secured Notes in a private placement.

LSB has used, or intends to use, the proceeds of $418 million, net of commissions and fees, from the sale of the Senior Secured Notes, in connection with the following:

| • |  | $67.2 million was used to repay all outstanding borrowings, including prepayment penalty, under the Secured Term Loan,

| • |  | for the construction and completion of an ammonia plant at the El Dorado Facility, which investment, when completed, will significantly decrease our costs and eliminate our exposure to fluctuations in the price of ammonia in the spot market,

| • |  | for the new 65% nitric acid plant and concentrator also at the El Dorado facility, which investment will replace lost capacity and add additional capacity to facilitate growth,

| • |  | for plant reliability enhancements, and environmental and safety upgrades at all of our chemical facilities, and

| • |  | for the development of our natural gas leasehold, which investment provides a partial hedge for the cost of natural gas, one of our key raw material inputs.

Pending application of proceeds discussed above, the net proceeds from the Senior Secured Notes are invested in highly rated money market funds, certificates of deposit and U.S. Treasury bills.

In connection with the closing, LSB entered into an indenture (the “Indenture”) governing the Senior Secured Notes. The Indenture contains covenants that, among other things, limit LSB’s ability, with certain exceptions and as defined in the Indenture, to certain transactions discussed below under “Loan Agreements-Terms and Conditions.”

Also, as discussed below under “Loan Agreements-Terms and Conditions,” on February 13, 2014, we and certain of our subsidiaries (the “Borrowers”) entered into an amended and restated revolving credit facility (the “Amended Working Capital Revolver Loan”), effective December 31, 2013. Pursuant to the terms of the Amended Working Capital Revolver Loan, the principal amount the Borrowers may borrow is up to $100.0 million, based on specific percentages of eligible accounts receivable and inventories. At December 31, 2013, there were no outstanding borrowings under the Amended Working Capital Revolver Loan. At December 31, 2013, the net credit available for borrowings under our Amended Working Capital Revolver Loan was approximately $67.0 million, based on our eligible collateral, less outstanding letters of credit as of that date.

As discussed below under “Loan Agreements-Terms and Conditions”, on February 1, 2013, Zena Energy L.L.C. (“Zena”), a subsidiary within our Chemical Business, entered into a loan (the “Secured Promissory Note”) with a lender in the original principal amount of $35 million.

Due to the overall increase in our outstanding long-term debt, our interest payment obligations have increased and will continue during future periods, of which a portion has and will be capitalized.

In November 2012, we filed a universal shelf registration statement on Form S-3, with the Securities and Exchange Commission (“SEC”). The shelf registration statement provides that we could offer and sell up to $200 million of our securities consisting of equity (common and preferred), debt (senior and subordinated), warrants and units, or a combination thereof. The shelf registration statement expires in November 2015 unless we decide to file a post-effective amendment. This disclosure shall not constitute an offer to sell or the solicitation of an offer to buy, nor shall there be any sale of these securities in any state in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state.

Income Taxes

We recognize and pay federal income taxes at regular corporate tax rates. With few exceptions, the 2010-2012 years remain open for all purposes of examination by the U.S. Internal Revenue Service (“IRS”) and other major tax jurisdictions. We are under examination by the IRS for the tax years 2008-2010. As of December 31, 2013, the IRS has proposed certain adjustments, which we are protesting. We anticipate that the adjustments, if any, will not result in a material change to our financial position. We had approximately $2.4 million accrued for various uncertain tax liabilities at December 31, 2013.

Capital Expenditures

Capital Expenditures-2013

Cash used for capital expenditures (including acquisition of working interests in natural gas properties for $9.2 million) during 2013 was $166.6 million, including $160.0 million for the benefit of our Chemical Business and $6.0 million for the benefit of our Climate Control Business. The Chemical Business capital expenditures relate primarily to expenditures to replace or rebuild damaged PP&E discussed above under “Downtime at Certain Chemical Facilities and Related Programs” and certain capital projects discussed below under “Committed and Planned Capital Expenditures,” but also includes approximately $3.0 million associated with maintaining compliance with environmental laws, regulations and guidelines. The capital expenditures were funded primarily from working capital, insurance proceeds, the net proceeds received in connection with the offering of our Senior Secured Notes, and other third-party financing. Due to the increase in the amount of capital expenditures incurred and committed, our depreciation, depletion and amortization expenses have increased and are expected to continue to increase during 2014.

Our committed capital expenditures are the capital projects that have been approved by management as of December 31, 2013 and include projects which are already in progress and funded or projects supported by cost benefit analysis. The additional planned capital expenditures are subject to economic conditions and continued review by management. The amount of planned capital expenditures may increase or decrease as new information is obtained or circumstances change. Total capital expenditures include all committed capital expenditures as well as expenditures that have been brought to the attention of management for approval through our budget and forecasting process.

At December 31, 2013, we had committed and planned capital expenditures as indicated in the table above. We plan to fund the committed and planned capital expenditures from noncurrent restricted cash and investments (provided from the proceeds from the Senior Secured Notes), working capital, internally generated cash flows, insurance proceeds, and third-party financing.

During the fourth quarter of 2013, we received the necessary permits to proceed with expansion projects at the El Dorado Facility which include the ammonia production plant discussed below under “Ammonia Plant”; a new 65% strength nitric acid plant and concentrator to replace the lost production from the DSN plant explosion; and for other support infrastructure. The expected cost of these projects is outlined below.

##### Table of Contents

The committed capital expenditures for Corporate and Other include $15 million to $20 million for the replacement of our enterprise financial and operations management software.

Ammonia Plant

Our El Dorado Facility produces nitric acid and agricultural and industrial grade AN from purchased ammonia, which is currently at a cost disadvantage compared to products produced from natural gas. We believe this cost disadvantage will continue to be significant for the medium and long-term. Using a portion of the net proceeds from the sale of the Senior Secured Notes, we are proceeding with the addition of an anhydrous ammonia production plant at the El Dorado Facility. During August 2013, a subsidiary of EDC entered into an agreement with SAIC Constructors, LLC to engineer and construct the ammonia plant and certain support facilities. The estimated construction cost of this project ranges from $250 million to $300 million and is expected to be complete by the end of 2015.

Purchase of Additional Gas Working Interest

During 2013, Zena, which is a subsidiary within our Chemical Business, acquired certain additional working interests in natural gas properties located in the Marcellus Shale in Wyoming County, Pennsylvania as a partial hedge against cost increases in natural gas that is a primary feedstock in the production of ammonia. The purchase represents an increase from approximately 10% to 12% in the total working interest (an increase from approximately 8% to 10% in total net revenue interest) for proven reserves in the same natural gas properties purchased by Zena in October 2012. The purchase price for the additional working interest paid by Zena was $9.2 million in cash, which was funded using our existing working capital. Our working interest represents our share of the costs and expenses incurred in connection with the underlying natural gas working interest leaseholds while our net revenue interest represents our share of the revenues from the sale of natural gas. The net revenue interest is less than our working interest as the result of royalty interest due to the royalty owners. We are not the operator of these natural gas properties.

The current development plan for the leaseholds includes 63 natural gas wells, of which 27 wells have been developed and are producing as of December 31, 2013. Zena’s portion of the estimated capital cost to fully develop the remaining leaseholds is approximately $32 million to be incurred through 2016. During 2013, Zena sold from their working interest approximately 2,600 MMcf of natural gas. Zena’s share of the estimated remaining proved reserves that are economically feasible to be recovered from known reservoirs based on current market conditions is approximately 70,000 MMcf of natural gas as estimated by an independent reservoir engineering firm based on petroleum and geoscience engineering data.

Information Request from EPA

As discussed above under “Environmental, Health and Safety Matters” of Part I of this report, in connection with a national enforcement initiative, the EPA had sent information requests pursuant to Section 114 of the Clean Air Act to most, if not all, of the operators of nitric acid plants in the U.S., including our El Dorado and Cherokee Facilities and the Baytown Facility operated by our subsidiary, El Dorado Nitric Company and its subsidiaries (“EDN”).

During 2013, we negotiated a global agreement in principle with the EPA/DOJ to settle this matter. During January 2014, we executed a formal Consent Decree to settle this matter and expect the DOJ to execute such and to obtain court approval of the executed Consent Decree to become effective during 2014. The agreement provides, among other things, the following:

| • |  | all of our Chemical Business’ nitric acid plants are to achieve certain emission rates within a certain time period for each plant. In order to achieve these emission rates, six of our Chemical Business’ eight nitric acid plants will require additional pollution control technology equipment to achieve the emission rates agreed upon for continued future operation of units. Currently, we have already completed necessary modifications at three of our Chemical Business’ existing nitric acid plants. The cost of the necessary pollution control equipment is estimated to range from $2.0 million to $3.0 million for each of the remaining five nitric acid plants, the cost of which will be capitalized when incurred;

36

##### Table of Contents

| • |  | our Chemical Business will provide a reforestation mitigation project that is unrelated to our emissions or activities and will not be located at one of our plant sites, which we estimate will cost approximately $150,000; and

| • |  | a civil penalty will be paid by our Chemical Business in the amount of $725,000.

Estimated Plant Turnaround Costs – 2014

Our Chemical Business expenses the costs for planned maintenance, repairs and minor renewal activities (“Turnarounds”) as they are incurred and are classified as cost of sales. Based on our current plan for Turnarounds during 2014, we estimate that we will incur approximately $5.0 million to $5.5 million of these Turnaround costs. These costs do not include the costs relating to lost absorption or reduced margins due to the associated plants being shut down. These costs also do not include maintenance and repair costs related to the current repairs and maintenance to bring the Pryor Facility back into production. We plan to fund these expenditures from our available working capital. However, it is possible that the actual costs could be significantly different from our estimates.

Expenses Associated with Environmental Regulatory Compliance

Our Chemical Business is subject to specific federal and state environmental compliance laws, regulations and guidelines. As a result, our Chemical Business incurred expenses of $5.2 million in 2013 in connection with environmental projects. For 2014, we expect to incur expenses ranging from $4.0 million to $5.0 million in connection with additional environmental projects. However, it is possible that the actual costs could be significantly different than our estimates.

Dividends

LSB is a holding company and, accordingly, its ability to pay cash dividends on its preferred stock and common stock depends in large part on its ability to obtain funds from its subsidiaries. Payment of dividends by LSB is limited under certain limited conditions under the terms of the Amended Working Capital Loan Agreement and the Senior Secured Notes as discussed below under “Loan Agreements-Terms and Conditions”.

Holders of our common stock and preferred stocks are entitled to receive dividends only when and if declared by our Board of Directors. We have not paid cash dividends on our outstanding common stock in many years, and we do not currently anticipate paying cash dividends on our outstanding common stock in the near future. However, our Board of Directors has not made a decision whether or not to pay such dividends on our common stock in 2014.

During the first quarter of 2013, dividends totaling $300,000 were declared on our outstanding preferred stock and subsequently paid in April 2013 using funds from our working capital. Each share of preferred stock is entitled to receive an annual dividend, only when declared by our Board of Directors, payable as follows:

| • |  | $0.06 per share on our outstanding non-redeemable Series D Preferred for an aggregate dividend of $60,000, and

| • |  | $12.00 per share on our outstanding non-redeemable Series B Preferred for an aggregate dividend of $240,000.

In January 2014, our Board of Directors declared the following dividends:

| • |  | $0.06 per share on our outstanding non-redeemable Series D Preferred for an aggregate dividend of $60,000, which were paid in February 2014, and

| • |  | $12.00 per share on our outstanding non-redeemable Series B Preferred for an aggregate dividend of $240,000, which were paid in February 2014.

All shares of the Series D Preferred and Series B Preferred are owned by the Golsen Group. There are no optional or mandatory redemption rights with respect to the Series B Preferred or Series D Preferred.

Compliance with Long—Term Debt Covenants

As discussed below under “Loan Agreements—Terms and Conditions”, the Amended Working Capital Revolver Loan requires, among other things, that we meet certain financial covenants. Currently, our forecast is that we will be able to meet all financial covenant requirements for the next twelve months.

Loan Agreements—Terms and Conditions

Senior Secured Notes –As discussed above under “Issuance of Senior Secured Notes and Intended Use of Proceeds,” on August 7, 2013, LSB sold $425 million aggregate principal amount of the Senior Secured Notes in a 144A transaction pursuant to the exemptions from the registration requirements of the Securities Act of 1933, as amended (the “Act”). The Senior Secured Notes are eligible for resale by the investors under Rule 144A under the Act. LSB received net proceeds of approximately $351 million, after the payoff of the Secured Term Loan, commissions and fees. In connection with the closing, LSB entered into an indenture (the “Indenture”) with UMB Bank, as trustee, and UMB Bank will also act as the collateral agent, in connection with the Senior Secured Notes, and will receive customary compensation from us for such services.

The Senior Secured Notes bear interest at the rate of 7.75% per year and mature on August 1, 2019. Interest is to be paid semiannually, beginning on February 1, 2014.

The Senior Secured Notes are general senior secured obligations of LSB. The Senior Secured Notes are jointly and severally and fully and unconditionally guaranteed by all of LSB’s current subsidiaries, with all of the guarantees, except two, being senior secured guarantees and two being senior unsecured guarantees. The Senior Secured Notes will rank equally in right of payment to all of LSB and the guarantors’ existing and future senior secured debt, including the Amended Working Capital Revolver Loan discussed below, and will be senior in right of payment to all of LSB and the guarantors’ future subordinated indebtedness. LSB does not have independent assets or operations.

Those subsidiaries that provided guarantees of the Senior Secured Notes will be released from such guarantees upon the occurrence of certain events, including the following:

| • |  | the designation of such guarantor as an unrestricted subsidiary;

| • |  | the release or discharge of any guarantee or indebtedness that resulted in the creation of the guarantee of the Senior Secured Notes by such guarantor;

| • |  | the sale or other disposition, including by way of merger or otherwise, of its capital stock or of all or substantially all of the assets, of such guarantor; or

| • |  | LSB’s exercise of its legal defeasance option or its covenant defeasance option as described in the Indenture with LSB’s obligations under the Indenture discharged in accordance with the Indenture.

The Senior Secured Notes will be effectively senior to all existing and future unsecured debt of LSB and the guarantors to the extent of the value of the property and assets subject to liens (“Collateral”) and will be effectively senior to all existing and future obligations under the Amended Working Capital Revolver Loan and other debt to the extent of the value of the certain collateral (“Priority Collateral”).

The Senior Secured Notes will be secured on a first-priority basis by the Notes’ Priority Collateral owned by LSB and the guarantors (other than the two unsecured guarantors) providing security and on a second-priority basis by the certain collateral securing the Amended Working Capital Revolver Loan owned by LSB and the guarantors (other than the two unsecured guarantors), in each case subject to certain liens permitted under the Indenture. The Senior Secured Notes will be equal in priority as to the Priority Collateral owned by LSB and the guarantors with respect to any obligations under any equally ranked lien obligations subsequently incurred.

The Senior Secured Notes will be effectively subordinated to all of LSB and the guarantors’ existing and future obligations under the Amended Working Capital Revolver Loan and other debt to the extent of the value of the certain collateral securing such debt and to any of LSB and the guarantors’ existing and future indebtedness that is secured by liens that are not part of the Collateral. The Senior Secured Notes will be structurally subordinated to all of the existing and future indebtedness, preferred stock obligations and other liabilities, including trade payables, of our subsidiaries that do not guarantee the Senior Secured Notes in the future.

38

##### Table of Contents

Except under certain conditions, the Senior Secured Notes are not redeemable before August 1, 2016. On or after such date, LSB may redeem the Senior Secured Notes at its option, in whole or in part, upon not less than 30 nor more than 60 days notice, at the following redemption prices (expressed as percentages of the principal amount thereof), plus accrued and unpaid interest to the redemption date (subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date), if redeemed during the twelve-month period commencing on August 1st of the year set forth below:

Year |  | Percentage |
2016 |  |  | 103.875 | %
2017 |  |  | 101.938 | %
2018 and thereafter |  |  | 100.000 | %

Upon the occurrence of a change of control, as defined in the Indenture, each holder of the Senior Secured Notes will have the right to require that LSB purchase all or a portion of such holder’s notes at a purchase price equal to 101% of the principal amount thereof plus accrued and unpaid interest, if any, to the date of purchase (subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date).

The Indenture contains covenants that, among other things, limit LSB’s ability, with certain exceptions and as defined in the Indenture, to:

| • |  | incur additional indebtedness;

| • |  | pay dividends;

| • |  | repurchase LSB’ common and preferred stocks;

| • |  | make investments;

| • |  | repay certain indebtedness;

| • |  | create liens on, sell or otherwise dispose of our assets;

| • |  | engage in mergers, consolidations or other forms of recapitalization;

| • |  | engage in sale-leaseback transactions; or

| • |  | engage in certain affiliate transactions.

Amended Working Capital Revolver Loan – On February 13, 2014, LSB and certain of its subsidiaries (the “Borrowers”) entered into an amendment to the existing senior secured revolving credit facility (the “Amended Working Capital Revolver”). The Amended Working Capital Revolver is effective as of December 31, 2013. Pursuant to the terms of the Amended Working Capital Revolver Loan, the Borrowers may borrow on a revolving basis up to $100.0 million, based on specific percentages of eligible accounts receivable and inventories and permits the Senior Secured Notes and the secured guarantees to be secured on a first-priority basis by the Priority Collateral and on a second-priority basis by the certain collateral securing the Amended Working Capital Revolver Loan and provides that the Amended Working Capital Revolver Loan be secured on a second-priority basis by the Priority Collateral. The Amended Working Capital Revolver Loan will mature on April 13, 2018.

The Amended Working Capital Revolver Loan accrues interest at a base rate (generally equivalent to the prime rate) plus 0.50% if borrowing availability is greater than $25.0 million, otherwise plus 0.75% or, at our option, accrues interest at LIBOR plus 1.50% if borrowing availability is greater than $25.0 million, otherwise LIBOR plus 1.75%. At December 31, 2013, the interest rate was 3.75% based on LIBOR. Interest is paid monthly, if applicable.

At December 31, 2013, there were no outstanding borrowings under the Amended Working Capital Revolver Loan. At December 31, 2013, the net credit available for borrowings under our Amended Working Capital Revolver Loan was approximately $67.0 million, based on our eligible collateral, less outstanding letters of credit as of that date.

The Amended Working Capital Revolver Loan provides for up to $15.0 million of letters of credit. All letters of credit outstanding reduce availability under the Amended Working Capital Revolver Loan. Under the Amended Working Capital Revolver Loan, the lender also requires the Borrowers to pay a letter of credit fee equal to 1% per annum of the undrawn amount of all outstanding letters of credit, an unused line fee equal to .25% per annum for the excess amount available under the Amended Working Capital Revolver Loan not drawn and various other audit, appraisal and valuation charges.

The lender has the ability to, upon an event of default, as defined, terminate the Amended Working Capital Revolver Loan and make the balance outstanding, if any, due and payable in full.

The Amended Working Capital Revolver Loan requires the Borrowers to meet a minimum fixed charge coverage ratio of not less than 1.10 to 1, if at any time the excess availability (as defined by the Amended Working Capital Revolver Loan), under the Amended Working Capital Revolver Loan, is less than or equal to $12.5 million. This ratio will be measured monthly on a trailing twelve month basis and as defined in the agreement. As of December 31, 2013, as defined in the agreement, the fixed charge coverage ratio was 6.6 to 1. The Amended Working Capital Revolver Loan contains covenants that, among other things, limit the Borrowers’ ability, without consent of the lender and with certain exceptions, to:

| • |  | incur additional indebtedness;

| • |  | create liens on, sell or otherwise dispose of our assets;

| • |  | engage in certain fundamental corporate changes or changes to our business activities;

| • |  | make certain material acquisitions;

| • |  | make other restricted payments, including investments;

| • |  | repay certain indebtedness;

| • |  | engage in certain affiliate transactions;

| • |  | declare dividends and distributions;

| • |  | engage in mergers, consolidations or other forms of recapitalization; or

| • |  | dispose of assets.

The Amended Working Capital Revolver Loan allows the Borrowers and subsidiaries under the Senior Secured Notes to guarantee those notes.

So long as both immediately before and after giving effect to any of the following, excess availability as defined by the Amended Working Capital Revolver Loan is equal to or greater than the greater of (x) 20% of the maximum revolver commitment or (y) $20 million, the Amended Working Capital Revolver will allow each of the Borrowers under the Amended Working Capital Revolver Loan to make:

| • |  | distributions and pay dividends by LSB with respect to amounts in excess of $0.5 million during each fiscal year;

| • |  | acquisitions of treasury stock by LSB with respect to amounts in excess of $0.5 million during each fiscal year;

| • |  | certain hedging agreements;

| • |  | investments in joint ventures and certain subsidiaries of LSB in an aggregate amount not exceeding $35.0 million; and

| • |  | other investments in an aggregate amount not exceeding $50.0 million at any one time outstanding.

The Amended Working Capital Revolver Loan includes customary events of default, including events of default relating to nonpayment of principal and other amounts owing under the Amended Working Capital Revolver Loan from time to time, any material misstatement or misrepresentation and breaches of representations and warranties made, violations of covenants, cross-payment default to indebtedness in excess of $2.5 million, cross-acceleration to indebtedness in excess of $2.5 million, bankruptcy and insolvency events, certain unsatisfied judgments, certain liens, and certain assertions of, or actual invalidity of, certain loan documents.

Secured Promissory Note—On February 1, 2013, Zena, a subsidiary within our Chemical Business, entered into the Secured Promissory Note with a lender in the original principal amount of $35 million. The Secured Promissory Note follows the original acquisition by Zena of Working Interests in certain natural gas properties during October 2012. The proceeds of the Secured Promissory Note effectively financed $35 million of the approximately $50 million purchase price of the Working Interests previously paid out of LSB’s working capital. The proceeds of the Secured Promissory Note were used to reimburse our general working capital. The Secured Promissory Note matures on February 1, 2016. Principal and interest are payable monthly based on a five-year amortization at a defined LIBOR rate plus 300 basis points with a final balloon payment of $15.3 million due at maturity. The interest rate at December 31, 2013 was 3.24%. The loan is secured by the Working Interests and related properties and proceeds.

Seasonality

We believe that our only significant seasonal products are fertilizer and related chemical products sold by our Chemical Business to the agricultural industry. The selling seasons for those products are primarily during the spring and fall planting seasons, which typically extend from March through June and from September through November in the geographical markets in which the majority of our agricultural products are distributed. As a result, our Chemical Business increases its inventory of agricultural products prior to the beginning of each planting season. In addition, the amount and timing of sales to the agricultural markets depend upon weather conditions and other circumstances beyond our control.

Related Party Transactions

On March 15, 2013, our Board of Directors appointed Mr. Lance Benham as a new member of our Board of Directors. Mr. Benham’s appointment fills the board vacancy resulting from the passing of Mr. Horace Rhodes in January 2013. At the 2013 annual meeting of stockholders held in May, Mr. Benham was elected to serve with the class of directors having a term that will expire in 2016. In January 2013, Mr. Benham retired as Senior Vice President of SAIC Energy, Environment & Infrastructure, LLC (“SAIC Energy”), a subsidiary of Science Applications International Corporation (“SAIC”). There are no arrangements or understandings between Mr. Benham and any other person pursuant to which Mr. Benham was appointed as a director of LSB. During 2012, we incurred approximately $0.1 million with SAIC Energy for engineering services relating to our chemical facilities. During 2013, we incurred approximately $11.7 million with SAIC Energy for engineering services and deconstruction services relating to our chemical facilities. During 2013, we negotiated several agreements with SAIC Constructors, LLC (“SAIC Constructors”), a subsidiary of SAIC, to engineer, procure and construct the ammonia plant, the Nitric Acid Plant, a nitric acid concentrator and certain support facilities. We expect SAIC Constructor’s fees in connection with these agreements to be approximately $39 million.

Results of Operations

The following Results of Operations should be read in conjunction with our consolidated financial statements for the years ended December 31, 2013, 2012, and 2011 and accompanying notes and the discussions above under “Overview” and “Liquidity and Capital Resources.”

We present the following information about our results of operations for our two core business segments: the Chemical Business and the Climate Control Business. The business operation classified as “Other” primarily sells industrial machinery and related components to machine tool dealers and end users. Net sales by business segment include net sales to unaffiliated customers as reported in the consolidated financial statements. Intersegment net sales are not significant. Gross profit by business segment represents net sales less cost of sales. In addition, our chief operating decision makers use operating income by business segment for purposes of making decisions that include resource allocations and performance evaluations. Operating income by business segment represents gross profit by business segment less selling, general and administrative expense (“SG&A”) incurred by each business segment plus other income and other expense earned/incurred by each business segment before general corporate expenses. General corporate expenses consist of SG&A, other income and other expense that are not allocated to one of our business segments.

The following table contains certain information about our continuing operations in different business segments for each of the three years ended December 31:

(1) | As a percentage of net sales

Net Sales—Chemical

| • |  | Agricultural products sales decreased due to the lack of available products as the result of the downtime experienced at our Cherokee and Pryor Facilities, lower sales prices for nitrogen fertilizer, and periodic adverse weather conditions during 2013.

| • |  | Industrial acids and other chemical products sales decreased due to the reduction in the average Tampa ammonia price by more than $57 per metric ton in 2013 compared to 2012 and its impact to pricing to certain of our industrial acid customers, the unplanned downtime at our Cherokee Facility, the reduction in production at our El Dorado Facility, and the timing and duration of a Turnaround performed at our Baytown Facility to coincide with a significant customer’s planned maintenance outage.

| • |  | Mining products sales decreased primarily due to a 44% decrease in volumes as the result of lower customer demand due to the current low cost of natural gas as an alternative fuel for utility companies and the downtime experienced at the Cherokee Facility.

| • |  | Natural gas sales relates to working interests in certain natural gas properties acquired in October 2012 and August 2013 by a subsidiary within our Chemical Business. Management considers these working interests as an economic hedge against a portion of a potential rise in natural gas prices in the future for a portion of our future natural gas production requirements.

Gross Profit—Chemical

Our Chemical Business’ gross profit was $46.2 million, including $28.6 million business interruption insurance recovery recognized. Excluding the insurance recovery, the decrease in gross profit of $72.8 million was primarily attributable to lower sales volume, unabsorbed fixed overhead costs, maintenance and repair costs, and costs associated with purchased ammonia and other products to meet some of our customers’ needs, all of which are primarily attributable to the downtime experienced at certain of our facilities, partially offset by $4.5 million precious metals recoveries during 2013. Additionally, gross margin percentages were impacted as the result of lower nitrogen fertilizer sale prices and higher natural gas feedstock costs. For 2012, the estimated cumulative impact from the downtime experienced at our facilities was approximately $32 million, which included unabsorbed fixed overhead costs, losses incurred on firm sales commitments, maintenance and repair costs, and other expenses, partially offset by $7.3 million business interruption insurance recovery.

##### Table of Contents

Operating Income—Chemical

Our Chemical Business’ operating income was $87.8 million, including the $66.0 million property insurance recovery recognized (classified as property insurance recoveries in excess of losses incurred) during 2013 partially offset by the decrease in gross profit as discussed above. Selling, general and administrative expenses increased approximately $3.3 million primarily due to consulting and other fees related to the El Dorado Facility, professional fees incurred at our Pryor Facility in connection with improving plant reliability. Additionally, other net expenses increased approximately $5.5 million primarily as a result of dismantle and demolition costs incurred at the El Dorado Facility and other income of $2.3 million recognized in 2012 (none in 2013) relating to a litigation settlement with a certain vendor.

Climate Control Business

The following table contains certain information about our net sales, gross profit and operating income in our Climate Control segment for 2013 and 2012:

(1) | As a percentage of net sales

Net Sales – Climate Control

| • |  | Net sales of our geothermal and water source heat pump products increased primarily as a result of a 17% improvement in sales of our commercial/institutional products with an increase in the number of units sold and higher unit pricing associated with product mix as well as reducing the level of backlog and an increase in new product orders during the year. Residential product sales improved 3% as a result of reducing the level of backlog, increased orders and higher unit pricing. During 2013, we continued to maintain a market share leadership position of approximately 40%, based on market data supplied by the Air-Conditioning, Heating and Refrigeration Institute (“AHRI”).

| • |  | Net sales of our hydronic fan coils increased primarily as a result of an increase in the number of units sold, unit pricing and product mix related to reducing the level of backlog and an increase in new product orders during the year. During 2013, we continued to have a market share leadership position of approximately 32% based on market data supplied by the AHRI.

| • |  | Net sales of our other HVAC products decreased primarily due to a decline in incoming orders for our large custom air handlers and for our engineering and construction services partially offset by increased sales of our modular chillers.

Gross Profit – Climate Control

The increase in gross profit in our Climate Control Business was primarily the result of the higher sales volume and unit pricing and change in product mix as discussed above. Gross profit as a percentage of sales improved primarily due to an improvement in raw material costs (copper, steel and aluminum) and overhead absorption related to the higher sales volume.

44

##### Table of Contents

Operating Income—Climate Control

Operating income increased as the result of the increase in gross profit discussed above partially offset by higher variable selling expenses of $2.0 million (including commission of $0.7 million, warranty of $0.6 million, and freight of $0.6 million) primarily as the result of higher sales volume, increased consulting fees of $1.2 million primarily for services focused on future process and cost savings improvements, and increased personnel costs of $3.9 million primarily related to the increase in the number of employees and healthcare benefits.

Interest Expense, net

Interest expense for 2013 was $14.0 million compared to $4.2 million for 2012. The increase is due primarily to the issuance of the Senior Secured Notes as discussed above under “Loan Agreements – Terms and Conditions” partially offset by $4.0 million of capitalized interest on capital projects, while under development and construction, during 2013 compared to $0.4 million capitalized during 2012.

Loss on Extinguishment of Debt

As the result of the payoff of the Secured Term Loan in 2013, we incurred a loss on extinguishment of debt of $1.3 million, consisting of a prepayment premium and writing off unamortized debt issuance costs.

Provision For Income Taxes

The provision for income taxes for 2013 was approximately $35.4 million compared to an income tax provision of $33.6 million for 2012. The resulting effective tax rate for 2013 and 2012 was 40% (excluding the benefit of $0.5 million associated with the retroactive tax relief on certain 2012 tax provisions that expired in 2012) and 36%, respectively. The increase in the effective tax rate was due primarily to the inability to take advantage of “domestic manufacturing deduction” as a result of the lower manufacturing income in 2013.

Net Sales – Chemical

Our Chemical Business reported a sales decrease for 2012 as a result of the following:

| • |  | Agricultural products sales—Agricultural products sales decreased $14.3 million, or 6%, primarily due to decreased sales volumes for UAN, which despite strong customer demand were lower due to reduced production as a result of downtime at our Cherokee and Pryor Facilities. This decrease was partially offset by increased ammonia sales as the Pryor Facility was able to produce and sell ammonia during a portion of the downtime. Due to strong market demand for crop nutrients and strong grain commodity prices, our agricultural grade AN and other products sold at our El Dorado Facility and distribution centers increased, which also helped to offset the loss of UAN sales.

| • |  | Industrial acids and other chemical products sales—Industrial acids and other products sales increased slightly primarily as the result of increased raw material costs including ammonia passed through pursuant to the terms of our contractual pricing contracts with customers.

| • |  | Mining products sales—Mining products sales decreased $21.9 million, or 19% primarily due to lower volumes as the result of the unplanned downtime at the El Dorado and Cherokee Facilities and the lower customer demand due to the current low cost of natural gas as an alternative fuel for utility companies and the current higher coal supply carried over from the warm winter in North America.

| • |  | Also see our discussion above under “Liquidity and Capital Resources – Capital Expenditures” concerning an acquisition of working interests in certain natural gas properties.

Gross Profit – Chemical

The decrease in gross profit of $33.0 million is primarily attributable to costs totaling $32.0 million due to the planned and unplanned downtime at our facilities during 2012, which includes unabsorbed fixed overhead costs, losses incurred on firm sales commitments, maintenance and repair costs, and other expenses.

Operating Income – Chemical

In spite of very strong agricultural supply and demand fundamentals, operating income declined $34.4 million primarily due to the decrease in gross profit as discussed above.

Net Sales – Climate Control

| • |  | Net sales of our geothermal and water source heat pump products decreased primarily as a result of a 21% decline in sales of our residential products, primarily due to the softness in the sector of the single-family residential construction market we serve. Sales of our commercial/institutional products also declined by 7% primarily due to the lower beginning backlog and lower order levels in the first part of the year, although order levels increased overall throughout the balance of 2012. During 2012, we continued to maintain a market share leadership position of approximately 40%, based on market data supplied by the AHRI.

| • |  | Net sales of our hydronic fan coils increased primarily due to increases in the number of units sold, the average unit selling price and in the sale of parts. During 2012, we continued to have a market share leadership position of approximately 30% based on market data supplied by the AHRI.

| • |  | Net sales of our other HVAC products in 2012 were 10% above the 2011 results and related to increased sales of our large custom air handlers.

Gross Profit—Climate Control

The decrease in gross profit in our Climate Control Business was primarily the result of the lower sales volume as discussed above. The gross profit percentage decline of 0.9% was primarily due to product mix, including a higher content of commercial products with lower gross margins than our residential products, and overhead absorption related to the lower sales volume.

Operating Income—Climate Control

Operating income decreased primarily as the result of the decrease in gross profit discussed above.

Provision For Income Taxes

The provision for income taxes for 2012 was $33.6 million compared to $46.2 million for 2011. The resulting effective tax rate for 2012 and 2011 was 36% for both periods. See additional discussion relating to income taxes above under “Liquidity and Capital Resources – Income Taxes.”

For 2013, net cash provided by continuing operating activities was $54.1 million primarily as the result of net income of $55.0 million plus adjustments of $35.3 million for deferred income taxes, and $28.3 million for depreciation, depletion and amortization of PP&E, partially offset by $66.3 million for gains on property insurance recoveries associated with PP&E.

Cash Flow from Continuing Investing Activities – 2013

Net cash used by continuing investing activities for 2013 was $389.6 million that consisted primarily of $290.9 million used for restricted cash and investments designated by management for specific capital projects primarily relating to our Chemical Business, $157.4 million for expenditures for PP&E of which $150.8 million is for the benefit of our Chemical Business, and $9.2 million for working interests in natural gas properties by our Chemical Business partially offset by $66.4 million of proceeds from property insurance recovery associated with PP&E.

Cash Flow from Continuing Financing Activities – 2013

Net cash provided by continuing financing activities for 2013 was $381.5 million that primarily consisted of net proceeds from long-term and short-term financing of $407.2 million, largely relating to the Senior Secured Notes and the Secured Promissory Note, partially offset by payments totaling $24.5 million on short-term financing and long-term debt.

Critical Accounting Policies and Estimates

The preparation of financial statements requires management to make estimates and assumptions that affect the reported amount of assets, liabilities, revenues and expenses, and disclosures of contingencies and fair values. For each of the last three years ended December 31, 2013, 2012, and 2011, we did not experience a material change in accounting estimates. However, it is reasonably possible that the estimates and assumptions utilized as of December 31, 2013 could change in the near term. In addition, the more critical areas of financial reporting impacted by management’s judgment, estimates and assumptions include the following:

Accrued Warranty Costs – Our Climate Control Business sells equipment that has an expected life, under normal circumstances and use, which extends over several years. As such, we provide warranties after equipment shipment/start up covering defects in materials and workmanship.

Our accounting policy and methodology for warranty arrangements is to measure and recognize the expense and liability for such warranty obligations at the time of sale using a percentage of sales and cost per unit of equipment, based upon our historical and estimated future warranty costs. We also recognize the additional warranty expense and liability to cover atypical costs associated with a specific product, or component thereof, or project installation, when such costs are probable and reasonably estimable. It is reasonably possible that our estimated accrued warranty costs could change in the near term.

Generally for commercial/institutional products, the base warranty coverage for most of the manufactured equipment in the Climate Control Business is limited to eighteen months from the date of shipment or twelve months from the date of start up, whichever is shorter, and to ninety days for spare parts. For residential products, the base warranty coverage for manufactured equipment in the Climate Control Business is limited to ten years from the date of shipment for material and to five years from the date of shipment for labor associated with the repair. The warranty provides that most equipment is required to be returned to the factory or an authorized representative and the warranty is limited to the repair and replacement of the defective product, with a maximum warranty of the refund of the purchase price. Furthermore, companies within the Climate Control Business generally disclaim and exclude warranties related to merchantability or fitness for any particular purpose and disclaim and exclude any liability for consequential or incidental damages. In some cases, the customer may purchase or a specific product may be sold with an extended warranty. The above discussion is generally applicable to such extended warranties, but variations do occur depending upon specific contractual obligations, certain system components, and local laws.

##### Table of Contents

At December 31, 2013 and 2012, our accrued product warranty obligations were $7.3 million and $6.2 million, respectively and are included in current and noncurrent accrued and other liabilities in the consolidated balance sheets. For 2013, 2012, and 2011, our warranty expense was $7.4 million, $6.7 million, and $6.5 million, respectively.

Contingencies – Certain conditions may exist which may result in a loss, but which will only be resolved when future events occur. We and our legal counsel assess such contingent liabilities, and such assessment inherently involves an exercise of judgment. If the assessment of a contingency indicates that it is probable that a loss has been incurred, we would accrue for such contingent losses when such losses can be reasonably estimated. If the assessment indicates that a potentially material loss contingency is not probable but reasonably possible, or is probable but cannot be estimated, the nature of the contingent liability, together with an estimate of the range of possible loss if determinable and material, would be disclosed. Estimates of potential legal fees and other directly related costs associated with contingencies are not accrued but rather are expensed as incurred. Loss contingency liabilities are included in current and noncurrent accrued and other liabilities and are based on current estimates that may be revised in the near term. In addition, we recognize contingent gains when such gains are realized or realizable and earned. We are a party to various litigation and other contingencies, the ultimate outcome of which is not presently known. Should the ultimate outcome of these contingencies be adverse, such outcome could adversely impact our liquidity, capital resources and results of operations.

Regulatory Compliance – Our Chemical Business is subject to specific federal and state regulatory compliance laws and guidelines. We have developed policies and procedures related to regulatory compliance. We must continually monitor whether we have maintained compliance with such laws and regulations and the operating implications, if any, and amount of penalties, fines and assessments that may result from noncompliance. We will also be obligated to manage certain discharge water outlets and monitor groundwater contaminants at our Chemical Business facilities should we discontinue the operations of a facility. At December 31, 2013, liabilities totaling $1.2 million have been accrued relating to these issues as discussed under “Environmental, Health and Safety Matters in Item 1 of this report. This liability is included in current accrued and other liabilities and is based on current estimates that may be revised in the near term.

Recognition of Insurance Recoveries – If an insurance claim relates to a recovery of our losses, we recognize the recovery when it is probable and reasonably estimable. If our insurance claim relates to a contingent gain, we recognize the recovery when it is realized or realizable and earned. At December 31, 2013 and 2012, the balance of the insurance claim receivable was $1.9 million and $10.1 million, respectively. An insurance recovery in excess of recoverable costs relating to a business interruption claim is a reduction to cost of sales. An insurance recovery in excess of recoverable costs relating to a property insurance claim is included in property insurance recoveries in excess of losses incurred. Also see discussion above under “Property and Business Interruption Insurance Claims and Recoveries”.

Management’s judgment and estimates in the above areas are based on information available from internal and external resources at that time. Actual results could differ materially from these estimates and judgments, as additional information becomes known.

Performance and Payment Bonds

We are contingently liable to sureties in respect of insurance bonds issued by the sureties in connection with certain contracts entered into by subsidiaries in the normal course of business. These insurance bonds primarily represent guarantees of future performance of our subsidiaries. As of December 31, 2013, we have agreed to indemnify the sureties for payments, up to $9.9 million, made by them in respect of such bonds. All of these insurance bonds are expected to expire or be renewed in 2014.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements as defined in Item 303(a)(4)(ii) of Regulation S-K under the Securities Exchange Act of 1934.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

General

Our results of operations and operating cash flows are impacted by changes in market prices of copper, steel, anhydrous ammonia and natural gas, changes in market currency exchange rates, and changes in market interest rates.

Forward Sales Commitments Risk

Periodically, our Chemical and Climate Control Businesses enter into forward firm sales commitments for products to be delivered in future periods. As a result, we could be exposed to embedded losses should our product costs exceed the firm sales prices. At December 31, 2013, we had a minimal amount of embedded losses associated with sales commitments with firm sales prices in our Chemical Business.

Commodity Price Risk

Our Chemical Business buys substantial quantities of anhydrous ammonia and natural gas as feedstocks generally at market prices and our Climate Control Business buys substantial quantities of copper and steel for use in manufacturing processes. As part of our raw material price risk management, periodically, our Chemical Business enters into firm purchase commitments and/or futures/forward contracts for anhydrous ammonia and natural gas and our Climate Control Business enters into futures contracts for copper. Our Chemical Business has also acquired working interests in natural gas properties to serve as an economic hedge against potential higher natural gas prices for a portion of our future natural gas requirements.

During 2013, certain subsidiaries within the Chemical Business entered into contracts to purchase natural gas for anticipated production needs. A portion of these contracts are considered derivatives and are accounted for on a mark-to-market basis and a portion of these contracts are considered normal purchases because they provide for the purchase of natural gas that will be delivered in quantities expected to be used over a reasonable period of time in the normal course of business and are documented as such, these contracts are exempt from the accounting and reporting requirements relating to derivatives. At December 31, 2013, the natural gas contracts accounted for on a mark-to-market basis were for approximately 1.5 million MMBtu of natural gas through October 2014 at a weighted-average cost of $3.98 per MMBtu ($6.1 million) and a weighted-average market value of $4.00 per MMBtu ($6.1 million). The natural gas contracts exempt from mark-to-market accounting were for approximately 1.6 million MMBtu of natural gas through May 2014 at the weighted-average cost of $3.47 per MMBtu ($5.6 million) and a weighted-average market value of $4.20 per MMBtu ($6.8 million) at December 31, 2013.

At December 31, 2013, we had no outstanding futures/forward copper contracts.

Interest Rate Risk

Our interest rate risk exposure results from our debt portfolio that is impacted by short-term rates, primarily variable-rate borrowings from commercial banks, and long-term rates, primarily fixed-rate notes, some of which prohibit prepayment or require a substantial premium payment with the prepayment.

As part of our interest rate risk management, we periodically purchase and/or enter into various interest rate contracts. At December 31, 2013, we have an interest rate swap, which sets a fixed three-month LIBOR of 3.23% on a declining balance (from $23.8 million to $18.8 million) for the period beginning April 2012 through March 2016. This contract is a free-standing derivative and is accounted for on a mark-to-market basis. At December 31, 2013, the fair value of these contracts (unrealized loss) was $1.2 million.

##### Table of Contents

At December 31, 2013 and 2012, we did not have any financial instruments with fair values significantly different from their carrying amounts, except for the Senior Secured Notes at December 31, 2013. The estimated fair value of the Senior Secured Notes exceeded the carrying value by approximately $20 million. The valuation is classified as Level 2 and is based on the range of ask/bid prices (104.5 to 104.9) for these notes but are currently traded in a limited and low volume market since these notes have not yet been registered. The valuations of our other long-term debt agreements are classified as Level 3 and are based on valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement. The fair value measurement of our long-term debt agreements are valued using a discounted cash flow model that calculates the present value of future cash flows pursuant to the terms of the debt agreements and applies estimated current market interest rates. The estimated current market interest rates are based primarily on interest rates currently being offered on borrowings of similar amounts and terms. In addition, no valuation input adjustments were considered necessary relating to nonperformance risk for our debt agreements. The fair value of financial instruments is not indicative of the overall fair value of our assets and liabilities since financial instruments do not include all assets, including intangibles, and all liabilities.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

We have included the financial statements and supplementary financial information required by this item immediately following Part IV of this report and hereby incorporate by reference the relevant portions of those statements and information into this Item 8.

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE

None.

ITEM 9A. CONTROLS AND PROCEDURES

As of the end of the period covered by this report, we carried out an evaluation, with the participation of our Principal Executive Officer and Principal Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15 under the Securities Exchange Act of 1934). Based upon that evaluation, our Principal Executive Officer and our Principal Financial Officer have concluded that our disclosure controls and procedures were effective. There were no changes to our internal control over financial reporting during the quarter ended December 31, 2013 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining effective internal control over financial reporting. Our internal control system was designed to provide reasonable assurance to our 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.

Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2013. In making this assessment, it used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control—Integrated Framework (1992 Framework). Based on our assessment, we believe that, as of December 31, 2013, our internal control over financial reporting is effective based on those criteria.

Our independent registered public accounting firm has issued an attestation report on our internal control over financial reporting. This report appears on the following page.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders of LSB Industries, Inc.

We have audited LSB Industries, Inc.’s internal control over financial reporting as of December 31, 2013 based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (1992 Framework) (the COSO criteria). LSB Industries, Inc.’s management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

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

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

In our opinion, LSB Industries, Inc. maintained, in all material respects, effective internal control over financial reporting as of December 31, 2013, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of LSB Industries, Inc. as of December 31, 2013 and 2012, and the related consolidated statements of income, stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2013 of LSB Industries, Inc. and our report dated February 26, 2014 expressed an unqualified opinion thereon.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders of LSB Industries, Inc.

We have audited the accompanying consolidated balance sheets of LSB Industries, Inc. as of December 31, 2013 and 2012, and the related consolidated statements of income, stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2013. Our audits also included the financial statement schedule listed in the Index at Item 15(a)(2). These financial statements and schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements and schedule based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of LSB Industries, Inc. at December 31, 2013 and 2012, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 2013, in conformity with U.S. generally accepted accounting principles. Also, in our opinion, the related financial statement schedule, when considered in relation to the basic financial statements taken as a whole, presents fairly in all material respects the information set forth therein.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), LSB Industries, Inc.’s internal control over financial reporting as of December 31, 2013, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (1992 Framework) and our report dated February 26, 2014 expressed an unqualified opinion thereon.

Notes to Consolidated Financial Statements

1. Summary of Significant Accounting Policies

Basis of Consolidation - LSB Industries, Inc. (“LSB”) and its subsidiaries (the “Company”, “We”, “Us”, or “Our”) are consolidated in the accompanying consolidated financial statements. We are involved in manufacturing and marketing operations. We are primarily engaged in the manufacture and sale of chemical products (the “Chemical Business”) and the manufacture and sale of geothermal and water source heat pumps and air handling products (the “Climate Control Business”). LSB is a holding company with no significant operations or assets other than cash, cash equivalents, and investments in its subsidiaries. Our Chemical Business’ ownership of working interests in natural gas properties is accounted for as an undivided interest, whereby we reflect our proportionate share of the underlying assets, liabilities, revenues and expenses. Our working interest represents our share of the costs and expenses incurred primarily to develop the underlying leaseholds and to produce natural gas while our net revenue interest represents our share of the revenues from the sale of natural gas. The net revenue interest is less than our working interest as the result of royalty interest due to others. We are not the operator of these natural gas properties. Entities that are 20% to 50% owned and for which we have significant influence are accounted for on the equity method. All material intercompany accounts and transactions have been eliminated.

Reclassifications - Reclassifications have been made in our consolidated balance sheet at December 31, 2012 to conform to our consolidated balance sheet at December 31, 2013, which reclassifications combined various current asset line items and combined various noncurrent other asset line items. These reclassifications did not impact the total amount of current assets or noncurrent other assets at December 31, 2012. In addition, reclassifications have been made in our consolidated statement of cash flows for 2011 and 2012 to conform to our consolidated statement of cash flows for 2013, which reclassifications combined various operating activities line items. These reclassifications did not impact the total amount of net cash provided by continuing operating activities for 2011 and 2012.

Use of Estimates - The preparation of consolidated financial statements in conformity with United States (“U.S.”) generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Business Combinations - We account for an acquired business using the acquisition method of accounting, which requires that the assets acquired and liabilities assumed be recorded at the date of acquisition at their respective fair values. If applicable, any excess of the purchase price over the estimated fair values of the net assets acquired is recorded as goodwill. Acquisition-related costs are recognized separately from the business combination and are expensed as incurred.

Cash and Cash Equivalents - Investments, which consist of highly liquid investments with original maturities of three months or less, are considered cash equivalents. At December, 31, 2013, the cash and cash equivalents balance exceeded the FDIC-insured limits by approximately $0.6 million. All of these cash balances were held by financial institutions within the U.S.

Accounts Receivable - Our accounts receivable are stated at net realizable value. This value includes an appropriate allowance for estimated uncollectible accounts to reflect any loss anticipated on accounts receivable balances. Our estimate is based on historical experience and periodic assessment of outstanding accounts receivable, particularly those accounts that are past due (based upon the terms of the sale). Our periodic assessment of our accounts receivable is based on our best estimate of amounts that are not recoverable.

Inventories - Inventories are stated at the lower of cost (determined using the first-in, first-out (“FIFO”) basis) or market (net realizable value). Finished goods and work-in-process inventories include material, labor, and manufacturing overhead costs. Additionally, we review inventories and record inventory reserves for slow-moving inventory items.

Precious Metals - Precious metals are used as a catalyst in the Chemical Business manufacturing process. Precious metals are carried at cost, with cost being determined using the FIFO basis. Because some of the catalyst consumed in the production process cannot be readily recovered and the amount and timing of recoveries are not predictable, we follow the practice of expensing precious metals as they are consumed. Occasionally, during major maintenance or capital projects, we may be able to perform procedures to recover precious metals (previously expensed) which have accumulated over time within the manufacturing equipment. Recoveries of precious metals are recognized at historical FIFO costs. When we accumulate precious metals in excess of our production requirements, we may sell a portion of the excess metals.

1. Summary of Significant Accounting Policies (continued)

Property, Plant and Equipment - Property, plant and equipment (“PP&E”) are stated at cost, net of accumulated depreciation, depletion and amortization (“DD&A”). Leases meeting capital lease criteria are capitalized in PP&E. Major renewals and improvements that increase the life, value, or productive capacity of assets are capitalized in PP&E while maintenance, repairs and minor renewals are expensed as incurred. In addition, maintenance, repairs and minor renewal costs relating to planned major maintenance activities (“Turnarounds”) in our Chemical Business are expensed as they are incurred.

As it relates to natural gas properties, leasehold costs, intangible drilling and other costs of successful wells and development dry holes are capitalized in PP&E based on successful efforts accounting. The costs of exploratory wells are initially capitalized in PP&E, but expensed if and when the well is determined to be nonproductive.

Interest cost on borrowings incurred during a significant construction or development project is capitalized primarily in PP&E. Capitalized interest is added to the underlying asset and amortized over the estimated useful lives of the assets. Fully depreciated assets are retained in PP&E and accumulated DD&A accounts until disposal. When PP&E are retired, sold, or otherwise disposed, the asset’s carrying amount and related accumulated DD&A are removed from the accounts and any gain or loss is included in other income or expense.

For financial reporting purposes, depreciation of the costs of PP&E is primarily computed using the straight-line method over the estimated useful lives of the assets. DD&A of the costs of producing natural gas properties are computed using the units of production method primarily on a field-by-field basis using proved or proved developed reserves, as applicable, as estimated by our independent consulting petroleum engineer. No provision for depreciation is made on construction in progress or capital spare parts until such time as the relevant assets are put into service. No provision for DD&A is made on nonproducing leasehold costs and exploratory wells in progress until such time as the relevant assets relate to proven reserves.

Our natural gas reserves are based on estimates and assumptions, which affect our DD&A calculations. Our independent consulting petroleum engineer, with our assistance, prepares estimates of natural gas reserves based on available relevant data and information. For DD&A purposes, and as required by the guidelines and definitions established by the Securities and Exchange Commission (“SEC”), the reserve estimates are based on average natural gas prices during the 12-month period, determined as an unweighted arithmetic average of the first-day-of-the-month price for each month.

Impairment of Long-Lived Assets - Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset (asset group) may not be recoverable. An impairment loss would be recognized when the carrying amount of an asset (asset group) exceeds the estimated undiscounted future cash flows expected to result from the use of the asset (asset group) and its eventual disposition. If assets to be held and used are considered to be impaired, the impairment to be recognized is the amount by which the carrying amounts of the assets exceed the fair values of the assets as measured by the present value of future net cash flows expected to be generated by the assets or their appraised value. As it relates to natural gas properties, proven natural gas properties are reviewed for impairment on a field-by-field basis and nonproducing leasehold costs are reviewed for impairment on a property-by-property basis.

In general, assets held for sale are reported at the lower of the carrying amounts of the assets or fair values less costs to sell. At December 31, 2013 and 2012, we had no long-lived assets classified as assets held for sale.

Noncurrent Restricted Cash - Noncurrent restricted cash consists of cash and cash equivalent balances that are designated by us for specific purposes relating to capital projects. At December 31, 2013, the noncurrent restricted cash balance exceeded the FDIC-insured limits by approximately $49.8 million. All of these cash balances were held by financial institutions within the U.S.

Noncurrent Restricted Investments - Noncurrent restricted investments consist of investment balances that are designated by us for specific purposes relating to capital projects. At December 31, 2013, the balance includes investments of $130 million of U.S. Treasury bills with an original maturity of 13 weeks and $80 million of certificates of deposits with an original maturity no longer than approximately 26 weeks. The investments in these U.S. Treasury bills are classified as held-to-maturity and are carried at amortized cost, which approximates fair value. The investments in certificates of deposits are carried at cost, which approximates fair value. The investments in certificates of deposits exceeded the FDIC-insured limits by approximately $79.8 million. All of these investments were held by financial institutions within the U.S.

Debt Issuance Costs - Debt issuance costs are amortized over the term of the associated debt instrument. In general, if debt is extinguished prior to maturity, the associated debt issuance costs, if any, are written off and included in the gain or loss on extinguishment of debt.

Goodwill - Goodwill is reviewed for impairment at least annually. An impairment loss generally would be recognized when the carrying amount of the reporting unit’s net assets exceeds the estimated fair value of the reporting unit. Reporting units are one level below the business segment level. No impairments of goodwill were incurred in 2013, 2012, or 2011. Goodwill relates to business acquisitions in prior periods in the following business segments:

|  | December 31, |
|  | 2013 |  |  | 2012 |
|  | (In Thousands) |
Chemical |  | $ | 1,621 |  |  | $ | 1,621 |
Climate Control |  |  | 103 |  |  |  | 103 |
Total goodwill |  | $ | 1,724 |  |  | $ | 1,724 |

Short-Term Financing - Our short-term financing relates to agreements entered into to finance a portion of our annual premiums for certain of our insurance policies.

Accrued Insurance Liabilities - We are self-insured up to certain limits for group health, workers’ compensation and general liability claims. Above these limits, we have commercial stop-loss insurance coverage for our contractual exposure on group health claims and statutory limits under workers’ compensation obligations. We also carry umbrella insurance of $100 million for most general liability and auto liability risks. We have a separate $50 million insurance policy covering pollution liability at our Chemical Business facilities. Additional pollution liability coverage for our other facilities is provided in our general liability and umbrella policies. As it relates to our natural gas properties within our Chemical Business that we do not operate but only own a working interest, insurance policies are maintained by the operator, which we are responsible for our proportionate share of the costs involved.

Our accrued self-insurance liabilities are based on estimates of claims, which include the reported incurred claims amounts plus the reserves established by our insurance adjustors and/or estimates provided by attorneys handling the claims, if any, up to the amount of our self-insurance limits. In addition, our accrued insurance liabilities include estimates of incurred, but not reported, claims based on historical claims experience. The determination of such claims and the appropriateness of the related liability is periodically reviewed and revised, if needed. Changes in these estimated liabilities are charged to operations. Potential legal fees and other directly related costs associated with insurance claims are not accrued but rather are expensed as incurred. Accrued insurance claims are included in accrued and other liabilities. It is reasonably possible that the actual development of claims could be different than our estimates.

Accrued Warranty Costs - Our Climate Control Business sells equipment that has an expected life, under normal circumstances and use, which extends over several years. As such, we provide warranties after equipment shipment/start up covering defects in materials and workmanship.

Our accounting policy and methodology for warranty arrangements is to measure and recognize the expense and liability for such warranty obligations at the time of sale using a percentage of sales and cost per unit of equipment, based upon our historical and estimated future warranty costs. We also recognize the additional warranty expense and liability to cover atypical costs associated with a specific product, or component thereof, or project installation, when such costs are probable and reasonably estimable. It is reasonably possible that our estimated accrued warranty costs could change in the near term.

1. Summary of Significant Accounting Policies (continued)

Executive Benefit Agreements - We have entered into benefit agreements with certain key executives. Costs associated with these individual benefit agreements are accrued based on the estimated remaining service period when such benefits become probable they will be paid. Total costs accrued equal the present value of specified payments to be made after benefits become payable.

Income Taxes - We recognize deferred tax assets and liabilities for the expected future tax consequences attributable to net operating loss (“NOL”) carryforwards, tax credit carryforwards, and differences between the financial statement carrying amounts and the tax basis of our assets and liabilities. We establish valuation allowances if we believe it is more-likely-than-not that some or all of deferred tax assets will not be realized. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

In addition, we do not recognize a tax benefit unless we conclude that it is more-likely-than-not that the benefit will be sustained on audit by the taxing authority based solely on the technical merits of the associated tax position. If the recognition threshold is met, we recognize a tax benefit measured at the largest amount of the tax benefit that, in our judgment, is greater than 50% likely to be realized. We record interest related to unrecognized tax positions in interest expense and penalties in operating other expense.

We reduce income tax expense for investment tax credits in the year the credit arises and is earned.

Income tax benefits associated with amounts that are deductible for income tax purposes but that do not affect earnings are credited to equity. These benefits are principally generated from exercises of non-qualified stock options.

Contingencies – Certain conditions may exist which may result in a loss, but which will only be resolved when future events occur. We and our legal counsel assess such contingent liabilities, and such assessment inherently involves an exercise of judgment. If the assessment of a contingency indicates that it is probable that a loss has been incurred, we would accrue for such contingent losses when such losses can be reasonably estimated. If the assessment indicates that a potentially material loss contingency is not probable but reasonably possible, or is probable but cannot be estimated, the nature of the contingent liability, together with an estimate of the range of possible loss if determinable and material, would be disclosed. Estimates of potential legal fees and other directly related costs associated with contingencies are not accrued but rather are expensed as incurred. Loss contingency liabilities are included in current and noncurrent accrued and other liabilities and are based on current estimates that may be revised in the near term. In addition, we recognize contingent gains when such gains are realized or realizable and earned.

Asset Retirement Obligations - In general, we record the estimated fair value of an asset retirement obligation (“ARO”) associated with tangible long-lived assets in the period it is incurred and when there is sufficient information available to estimate the fair value. An ARO associated with long-lived assets is a legal obligation under existing or enacted law, statute, written or oral contract or legal construction. AROs, which are initially recorded based on estimated discounted cash flows, are accreted to full value over time through charges to cost of sales. In addition, we capitalize the corresponding asset retirement cost as PP&E, which cost is depreciated or depleted over the related asset’s respective useful life. We do not have any assets restricted for the purpose of settling our AROs.

Stock Options - Equity award transactions with employees are measured based on the estimated fair value of the equity awards issued. For equity awards with only service conditions that have a graded vesting period, we recognize compensation cost on a straight-line basis over the requisite service period for the entire award. In addition, we issue new shares of common stock upon the exercise of stock options.

Revenue Recognition - We recognize revenue for substantially all of our operations at the time title to the goods transfers to the buyer and there remain no significant future performance obligations by us. Revenue relating to construction contracts is recognized using the percentage-of-completion method based primarily on contract costs incurred to date compared with total estimated contract costs. Changes to total estimated contract costs or losses, if any, are recognized in the period in which they are determined. Sales of warranty contracts are recognized as revenue ratably over the life of the contract. See discussion above under “Accrued Warranty Costs” for our accounting policy for recognizing warranty expense.

1. Summary of Significant Accounting Policies (continued)

Recognition of Insurance Recoveries - If an insurance claim relates to a recovery of our losses, we recognize the recovery when it is probable and reasonably estimable. If our insurance claim relates to a contingent gain, we recognize the recovery when it is realized or realizable and earned. Amounts recoverable from our insurance carriers, if any, are included in accounts receivable. An insurance recovery in excess of recoverable costs relating to a business interruption claim, if any, is a reduction to cost of sales. An insurance recovery in excess of recoverable costs relating to a property insurance claim, if any, is included in property insurance recoveries in excess of losses incurred.

Cost of Sales - Cost of sales includes materials, labor and overhead costs to manufacture the products sold plus inbound freight, purchasing and receiving costs, inspection costs, internal transfer costs and warehousing costs (excluding certain handling costs directly related to loading product being shipped to customers in our Chemical Business which are included in selling, general and administrative expense). Maintenance, repairs and minor renewal costs relating to Turnarounds in our Chemical Business are included in cost of sales as they are incurred. Precious metals used as a catalyst (Chemical Business) and consumed during the manufacturing process are included in cost of sales. Recoveries and gains from precious metals (Chemical Business), sales of scrap material (Climate Control Business), and business interruption insurance claims are reductions to cost of sales. Provisions for (realization of) losses associated with inventory reserves, gains and losses (realized and unrealized) from our commodities and foreign currency futures/forward contracts, and provision for losses, if any, on firm sales commitments are included in cost of sales.

Selling, General and Administrative Expense - Selling, general and administrative expense (“SG&A”) includes costs associated with the sales, marketing and administrative functions. Such costs include personnel costs, including benefits, advertising costs, commission expenses, warranty costs, office and occupancy costs associated with the sales, marketing and administrative functions. SG&A also includes certain handling costs directly related to product being shipped to customers in our Chemical Business and outbound freight in our Climate Control Business. These handling costs primarily consist of personnel costs for loading product into transportation equipment, rent and maintenance costs related to the transportation equipment, and certain indirect costs. In addition, professional fees are included in SG&A.

Shipping and Handling Costs – Shipping and handling costs included in net sales and SG&A for each business segment are as follows:

|  | 2013 |  |  | 2012 |  |  | 2011 |
|  | (In Thousands) |
Chemical: |  |  |  |  |  |  |  |  |  |  |  |
Shipping costs - Net sales (1) |  | $ | 21,954 |  |  | $ | 23,395 |  |  | $ | 26,179 |

Climate Control: |  |  |  |  |  |  |  |  |  |  |  |
Shipping and handling costs - SG&A (2) |  | $ | 9,520 |  |  | $ | 8,897 |  |  | $ | 8,564 |

(1) | These costs relate to amounts billed to our customers.

(2) | See discussions above under “Selling, General and Administrative Expense.”

Advertising Costs - Costs in connection with advertising and promotion of our products are expensed as incurred. These costs, primarily relating to our Climate Control Business, are as follows.

|  | 2013 |  |  | 2012 |  |  | 2011 |
|  | (In Thousands) |
Advertising costs |  | $ | 3,157 |  |  | $ | 3,365 |  |  | $ | 4,528 |

Derivatives, Hedges, Financial Instruments and Carbon Credits - Derivatives are recognized in the balance sheet and are measured at fair value. Changes in fair value of derivatives are recorded in results of operations unless the normal purchase or sale exceptions apply or hedge accounting is elected.

The assets for climate reserve tonnes (“carbon credits”) are recognized in the balance sheet and are measured at fair value.

Changes in fair value of carbon credits are recorded in results of operations. The liabilities for contractual obligations associated with carbon credits are recognized in the balance sheet and are measured at fair value unless we enter into a firm sales commitment to sell the associated carbon credits. When we enter into a firm sales commitment, the sales price, pursuant to the terms of the firm sales commitment, establishes the amount of the liability for the contractual obligation. Changes in fair value of contractual obligations associated with carbon credits are recorded in results of operations.

Income per Common Share - Net income applicable to common stock is computed by adjusting net income by the amount of preferred stock dividends and dividend requirements, if applicable. Basic income per common share is based upon net income applicable to common stock and the weighted-average number of common shares outstanding during each year. Diluted income per share is based on net income applicable to common stock plus preferred stock dividends and dividend requirements on preferred stock assumed to be converted, if dilutive, and interest expense including amortization of debt issuance cost, net of income taxes, on convertible debt assumed to be converted, if dilutive, and the weighted-average number of common shares and dilutive common equivalent shares outstanding, and the assumed conversion of dilutive convertible securities outstanding.

Our sales to contractors and independent sales representatives are generally subject to a mechanic’s lien or band protection in the Climate Control Business. Sales to other customers are generally unsecured. Credit is extended to customers based on an evaluation of the customer’s financial condition and other factors. Concentrations of credit risk with respect to trade receivables are monitored and this risk is reduced due to the large number of customers comprising our customer bases and their dispersion across many different industries and geographic areas (primarily as it relates to the Climate Control Business) and payment terms of 15 days or less relating to most of our significant customers in the Chemical Business. Nine customers (including their affiliates), primarily relating to the Chemical Business, account for approximately 31% of our total net receivables at December 31, 2013.

One of our subsidiaries, El Dorado Chemical Company (“EDC”), is party to an agreement with Bank of America, N.A. (the “Bank”) to sell our accounts receivables generated from product sales to a certain customer. We agreed to enter into this agreement as a courtesy to this customer. The term of this agreement matures in August 2014, with renewal options, but either party has an option to terminate the agreement pursuant to the terms of the agreement. In addition, we amended our sales agreement with the customer to offer extended payment terms under the condition that they pay an extended payment terms premium equal to the discount taken by the Bank when the accounts receivables are sold. Thus, there is no gain or loss from the sale of these receivables to the Bank. We have no continuing involvement or risks associated with the transferred accounts receivable. Pursuant to the terms of the agreement, EDC is to receive payment from the Bank no later than one business day after the Bank’s acceptance of EDC’s offer to sell the accounts receivables. As of December 31, 2013, EDC has been paid by the Bank for the accounts receivables sold to the Bank. We account for these transfers as sales under ASC 860 – Transfers and Servicing.

7. Accrued Warranty Costs

Our Climate Control Business sells equipment that has an expected life, under normal circumstances and use, which extends over several years. As such, we provide warranties after equipment shipment/start up covering defects in materials and workmanship. Generally for commercial/institutional products, the base warranty coverage for most of the manufactured equipment in the Climate Control Business is limited to eighteen months from the date of shipment or twelve months from the date of start up, whichever is shorter, and to ninety days for spare parts. For residential products, the base warranty coverage for manufactured equipment in the Climate Control Business is limited to ten years from the date of shipment for material and to five years from the date of shipment for labor associated with the repair. The warranty provides that most equipment is required to be returned to the factory or an authorized representative and the warranty is limited to the repair and replacement of the defective product, with a maximum warranty of the refund of the purchase price. Furthermore, companies within the Climate Control Business generally disclaim and exclude warranties related to merchantability or fitness for any particular purpose and disclaim and exclude any liability for consequential or incidental damages. In some cases, the customer may purchase or a specific product may be sold with an extended warranty. The above discussion is generally applicable to such extended warranties, but variations do occur depending upon specific contractual obligations, certain system components, and local laws.

Changes in our product warranty obligation (accrued warranty costs) are as follows:

8. Asset Retirement Obligations

Currently, we have various requirements at our Chemical Business facilities, including the disposal of wastewater generated at certain of these facilities. Additionally, we have certain facilities in our Chemical Business that contain asbestos insulation around certain piping and heated surfaces, which we plan to maintain or replace, as needed, with non-asbestos insulation through our standard repair and maintenance activities to prevent deterioration. Currently, there is insufficient information to estimate the fair value for most of our AROs. In addition, we currently have no plans to discontinue the use of these facilities, and the remaining life of the facilities is indeterminable. As a result, a liability for only a minimal amount relating to AROs associated with these facilities has been established. However, we will continue to review these obligations and record a liability when a reasonable estimate of the fair value can be made. In addition, our Chemical Business owns working interests

in certain natural gas properties. We recognized AROs associated with the obligation to plug and abandon wells when the natural gas reserves in the wells are depleted. At December 31, 2013 and 2012, our accrued liability for AROs was $304,000 and $154,000, respectively.

(A) | Effective December 31, 2013, LSB and certain of its wholly-owned subsidiaries (the “Borrowers”) entered into an amendment to the existing senior secured revolving credit facility (the “Amended Working Capital Revolver”). Pursuant to the terms of the Amended Working Capital Revolver Loan, the Borrowers may borrow on a revolving basis up to $100.0 million, based on specific percentages of eligible accounts receivable and inventories. In addition, the Amended Working Capital Revolver Loan and the Senior Secured Notes are cross collateralized as discussed in (B) below. The Amended Working Capital Revolver Loan will mature on April 13, 2018.

The Amended Working Capital Revolver Loan accrues interest at a base rate (generally equivalent to the prime rate) plus 0.50% if borrowing availability is greater than $25.0 million, otherwise plus 0.75% or, at our option, accrues interest at LIBOR plus 1.50% if borrowing availability is greater than $25.0 million, otherwise LIBOR plus 1.75%. At December 31, 2013, the interest rate was 3.75% based on LIBOR. Interest is paid monthly, if applicable.

The Amended Working Capital Revolver Loan provides for up to $15.0 million of letters of credit. All letters of credit outstanding reduce availability under the Amended Working Capital Revolver Loan. As of December 31, 2013, the amount available for borrowing under the Amended Working Capital Revolver Loan was approximately $67.0 million. Under the Amended Working Capital Revolver Loan, the lender also requires the Borrowers to pay a letter of credit fee equal to 1% per annum of the undrawn amount of all outstanding letters of credit, an unused line fee equal to .25% per annum for the excess amount available under the Amended Working Capital Revolver Loan not drawn and various other audit, appraisal and valuation charges.

The lender has the ability to, upon an event of default, as defined, terminate the Amended Working Capital Revolver Loan and make the balance outstanding, if any, due and payable in full.

The Amended Working Capital Revolver Loan requires the Borrowers to meet a minimum fixed charge coverage ratio of not less than 1.10 to 1, if at any time the excess availability (as defined by the Amended Working Capital Revolver Loan), under the Amended Working Capital Revolver Loan, is less than or equal to $12.5 million. This ratio will be measured monthly on a trailing twelve month basis and as defined in the agreement. The Amended Working Capital Revolver Loan contains covenants that, among other things, limit the Borrowers’ ability, without consent of the lender and with certain exceptions, to:

| • |  | engage in certain affiliate transactions;

| • |  | declare dividends and distributions;

| • |  | engage in mergers, consolidations or other forms of recapitalization; or

| • |  | dispose assets.

The Amended Working Capital Revolver Loan allows the Borrowers and subsidiaries under the Senior Secured Notes to guarantee those notes.

So long as both immediately before and after giving effect to any of the following, excess availability as defined by the Amended Working Capital Revolver Loan is equal to or greater than the greater of (x) 20% of the maximum revolver commitment or (y) $20 million, the Amended Working Capital Revolver will allow each of the Borrowers under the Amended Working Capital Revolver Loan to make:

| • |  | distributions and pay dividends by LSB with respect to amounts in excess of $0.5 million during each fiscal year;

| • |  | acquisitions of treasury stock by LSB with respect to amounts in excess of $0.5 million during each fiscal year;

| • |  | certain hedging agreements;

| • |  | investments in joint ventures and certain subsidiaries of LSB in an aggregate amount not exceeding $35.0 million; and

| • |  | other investments in an aggregate amount not exceeding $50.0 million at any one time outstanding.

The Amended Working Capital Revolver Loan includes customary events of default, including events of default relating to nonpayment of principal and other amounts owing under the Amended Working Capital Revolver Loan from time to time, any material misstatement or misrepresentation and breaches of representations and warranties made, violations of covenants, cross-payment default to indebtedness in excess of $2.5 million, cross-acceleration to indebtedness in excess of $2.5 million, bankruptcy and insolvency events, certain unsatisfied judgments, certain liens, and certain assertions of, or actual invalidity of, certain loan documents.

(B) | On August 7, 2013, LSB sold $425 million aggregate principal amount of the 7.75% Senior Secured Notes due 2019 (the “Senior Secured Notes”) in a 144A transaction pursuant to the exemptions from the registration requirements of the Securities Act of 1933, as amended (the “Act”). The Senior Secured Notes are eligible for resale by the investors under Rule144A under the Act. LSB received net proceeds of approximately $351 million, after the payoff of a secured term loan (discussed below), commissions and fees. In connection with the closing, LSB entered into an indenture (the “Indenture”) with UMB Bank, as trustee, governing the Senior Secured Notes and as collateral agent, and will receive customary compensation from us for such services.

The Senior Secured Notes bear interest at the rate of 7.75% per year and mature on August 1, 2019. Interest is to be paid semiannually, beginning on February 1, 2014.

The Senior Secured Notes are general senior secured obligations of LSB. The Senior Secured Notes are jointly and severally and fully and unconditionally guaranteed by all of LSB’s current wholly-owned subsidiaries, with all of the guarantees, except two, being senior secured guarantees and two being senior unsecured guarantees. The Senior Secured Notes will rank equally in right of payment to all of LSB and the guarantors’ existing and future senior secured debt, including the Amended Working Capital Revolver Loan discussed below, and will be senior in right of payment to all of LSB and the guarantors’ future subordinated indebtedness. LSB does not have independent assets or operations.

Those subsidiaries that provided guarantees of the Senior Secured Notes will be released from such guarantees upon the occurrence of certain events, including the following:

9. Long-Term Debt (continued)

| • |  | the designation of such guarantor as an unrestricted subsidiary;

| • |  | the release or discharge of any guarantee or indebtedness that resulted in the creation of the guarantee of the Senior Secured Notes by such guarantor;

| • |  | the sale or other disposition, including by way of merger or otherwise, of its capital stock or of all or substantially all of the assets, of such guarantor; or

| • |  | LSB’s exercise of its legal defeasance option or its covenant defeasance option as described in the Indenture with LSB’s obligations under the Indenture discharged in accordance with the Indenture.

The Senior Secured Notes will be effectively senior to all existing and future unsecured debt of LSB and the guarantors to the extent of the value of the property and assets subject to liens (“Collateral”) and will be effectively senior to all existing and future obligations under the Amended Working Capital Revolver Loan and other debt to the extent of the value of the certain collateral (“Priority Collateral”).

The Senior Secured Notes will be secured on a first-priority basis by the Priority Collateral owned by LSB and the guarantors (other than the two unsecured guarantors) and on a second-priority basis by the certain collateral securing the Amended Working Capital Revolver Loan owned by LSB and the guarantors (other than the two unsecured guarantors), in each case subject to certain liens permitted under the Indenture. The Senior Secured Notes will be equal in priority as to the Priority Collateral owned by LSB and the guarantors with respect to any obligations under any equally ranked lien obligations subsequently incurred. At December 31, 2013, the carrying value of the assets secured on a first-priority basis was approximately $410 million and the carrying value of the assets secured on a second-priority basis was approximately $128 million.

The Senior Secured Notes will be effectively subordinated to all of LSB and the guarantors’ existing and future obligations under the Amended Working Capital Revolver Loan and other debt to the extent of the value of the certain collateral securing such debt and to any of LSB and the guarantors’ existing and future indebtedness that is secured by liens that are not part of the Collateral. The Senior Secured Notes will be structurally subordinated to all of the existing and future indebtedness, preferred stock obligations and other liabilities, including trade payables, of our subsidiaries that do not guarantee the Senior Secured Notes in the future.

Except under certain conditions, the Senior Secured Notes are not redeemable before August 1, 2016. On or after such date, LSB may redeem the Senior Secured Notes at its option, in whole or in part, upon not less than 30 nor more than 60 days notice, at the following redemption prices (expressed as percentages of the principal amount thereof), plus accrued and unpaid interest to the redemption date (subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date), if redeemed during the twelve-month period commencing on August 1st of the year set forth below:

Year |  | Percentage |
2016 |  |  | 103.875 | %
2017 |  |  | 101.938 | %
2018 and thereafter |  |  | 100.000 | %

Upon the occurrence of a change of control, as defined in the Indenture, each holder of the Senior Secured Notes will have the right to require that LSB purchase all or a portion of such holder’s notes at a purchase price equal to 101% of the principal amount thereof plus accrued and unpaid interest, if any, to the date of purchase (subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date).

The Indenture contains covenants that, among other things, limit LSB’s ability, with certain exceptions and as defined in the Indenture, to:

| • |  | engage in certain affiliate transactions.

As discussed above, approximately $67.2 million of the proceeds from Senior Secured Notes was used to pay all outstanding borrowings, including the prepayment premium, under a term loan facility (the “Secured Term Loan”). As a result of the payoff of the Secured Term Loan, we incurred a loss on extinguishment of debt of $1.3 million, consisting of the prepayment premium and writing off unamortized debt issuance costs.

In connection with the Senior Secured Notes, LSB entered into a Registration Rights Agreement (the “Registration Rights Agreement”). Pursuant to the Registration Rights Agreement, we have agreed to use our reasonable best efforts to file with the SEC a registration statement (“Registration Statement”) on an appropriate form with respect to a registered offer to exchange the notes for new notes with terms substantially identical in all material respects to the notes, cause the Registration Statement to be declared effective under the Securities Act, and complete the exchange within 180 days after the effective date of such Registration Statement. We are also obligated to update the Registration Statement by filing a post-effective amendment. If the exchange offer is not completed on or prior to the expiration of 365 days from August 7, 2013 (the date of closing) and under certain other conditions, the annual interest rate on the notes will be increased by (i) 0.25% (or approximately $3,000 per day) for the first 90 day period immediately following such default and (ii) an additional 0.25% with respect to each subsequent 90 day period, in each case until and including the date such default ends, up to a maximum increase of 1.00% (or approximately $12,000 per day).

(C) | On February 1, 2013, Zena Energy L.L.C. (“Zena”), a subsidiary within our Chemical Business, entered into a loan (the “Secured Promissory Note”) with a lender in the original principal amount of $35 million. The Secured Promissory Note follows the original acquisition by Zena of working interests (“Working Interests”) in certain natural gas properties during October 2012. The proceeds of the Secured Promissory Note effectively financed $35 million of the approximately $50 million purchase price of the Working Interests previously paid out of LSB’s working capital. The Secured Promissory Note matures on February 1, 2016.

Principal and interest are payable monthly based on a five-year amortization at a defined LIBOR rate plus 300 basis points with a final balloon payment of $15.3 million due at maturity. The interest rate at December 31, 2013 was 3.24%. The loan is secured by the Working Interests and related properties and proceeds.

10. Income Taxes

Provisions for income taxes are as follows:

|  | 2013 |  |  | 2012 |  |  | 2011 |
|  | (In Thousands) |
Current: |  |  |  |  |  |  |  |  |  |  |  |
Federal |  | $ | (1,225 | ) |  | $ | 28,654 |  |  | $ | 33,006 |
State |  |  | 1,357 |  |  |  | 4,695 |  |  |  | 4,514 |
Total Current |  | $ | 132 |  |  | $ | 33,349 |  |  | $ | 37,520 |
Deferred: |  |  |  |  |  |  |  |  |  |  |  |
Federal |  | $ | 32,197 |  |  | $ | 559 |  |  | $ | 7,543 |
State |  |  | 3,092 |  |  |  | (314 | ) |  |  | 1,145 |
Total Deferred |  | $ | 35,289 |  |  | $ | 245 |  |  | $ | 8,688 |
Provisions for income taxes |  | $ | 35,421 |  |  | $ | 33,594 |  |  | $ | 46,208 |

The current provision for federal income taxes shown above includes regular federal income tax after the consideration of permanent and temporary differences between income for GAAP and tax purposes. In connection with the American Taxpayer Relief Act of 2012 that was signed into law in January 2013, we recorded a one-time benefit of approximately $0.5 million related to the retroactive tax relief for certain tax provisions that expired in 2012. Because the legislation was signed into law after December 31, 2012, the retroactive effects of the law reduced the current provision for 2013 and impacted the effective tax rate for 2013. The current provision for state income taxes includes regular state income tax and provisions for uncertain income tax positions

The deferred tax provision results from the recognition of changes in our prior year deferred tax assets and liabilities, and the utilization of state NOL carryforwards and other temporary differences. We reduce income tax expense for tax credits in the year they arise and are earned. At December 31, 2013, our gross amount of the investment tax credits available to offset state income taxes was minimal. These investment tax credits do not expire and carryforward indefinitely. The gross amount of federal tax credits was $905,000. These credits carryforward for 20 years.

We utilized approximately $0.1 million, $0.1 million and $0.2 million of state NOL carryforwards to reduce tax liabilities in 2013, 2012 and 2011, respectively. At December 31, 2013, we have remaining federal and state tax NOL carryforwards of $29.9 million and $43.6 million, respectively, which amounts exclude the NOL carryforwards that are related to unrecognized tax benefits and stock compensation that have not been recognized in accordance with GAAP. Additionally, we had approximately $22 million of alternative minimum tax (“AMT”) NOL carryforwards, net of unrecognized tax benefits, available as a deduction against future AMT income. The state NOL carryforwards begin expiring in 2014.

We considered both positive and negative evidence in our determination of the need for valuation allowances for the deferred tax assets associated with federal and state NOLs and federal credits. For 2013, 2012 and 2011, we determined it was more-likely-than-not that approximately $8.3 million, $6.8 million and $6.9 million, respectively, of the state NOL carryforwards would not be able to be utilized before expiration and a valuation allowance was maintained for the deferred tax assets associated with these state NOL carryforwards, net of federal benefit of approximately $0.3 million for each of the respective years.

When non-qualified stock options (“NSOs”) are exercised, the grantor of the options is permitted to deduct the spread between the fair market value of the stock issued and the exercise price of the NSOs as compensation expense in determining taxable income. Income tax benefits related to stock-based compensation deductions in excess of the compensation expense recorded for financial reporting purposes are not recognized in earnings as a reduction of income tax expense for financial reporting purposes. As a result, the stock-based compensation deduction recognized in our income tax return will exceed the stock-based compensation expense recognized in earnings. The excess tax benefit realized (i.e., the resulting reduction in the current tax liability) related to the excess stock-based compensation tax deduction of, $0.5 million and $1.3 million in 2012 and 2011, respectively, (none in 2013) which is included in the net change in capital in excess of par value rather than a decrease in the provision for income taxes.

10. Income Taxes (continued)

In addition, if the grantor of NSOs will not currently reduce its tax liability from the excess tax benefit deduction taken at the time of the taxable event (option exercised) because it has a NOL carryforward that is increased by the excess tax benefit, then the tax benefit should not be recognized until the deduction actually reduces current taxes payable. The amounts included in the federal and state NOL carryforwards but not reflected in deferred tax assets at December 31, 2013 totaled $1.4 million and $1.0 million, respectively. At December 31, 2013, we had $0.5 million of unrecognized federal and state tax benefits resulting from the exercise of NSOs (none at December 31, 2012).

10. Income Taxes (continued)

All of our income before taxes relates to domestic operations. Detailed below are the differences between the amount of the provision for income taxes and the amount which would result from the application of the federal statutory rate to “Income from continuing operations before provision for income taxes”.

|  | 2013 |  |  | 2012 |  |  | 2011 |
|  | (In Thousands) |
Provisions for income taxes at federal statutory rate |  | $ | 31,697 |  |  | $ | 32,391 |  |  | $ | 45,567 |
State current and deferred income taxes |  |  | 3,916 |  |  |  | 3,533 |  |  |  | 5,088 |
Domestic production activities deduction |  |  | — |  |  |  | (1,933 | ) |  |  | (3,091 | )
Effect of tax return to tax provision reconciliation |  |  | (318 | ) |  |  | (216 | ) |  |  | (958 | )
Other |  |  | 126 |  |  |  | (181 | ) |  |  | (398 | )
Provisions for income taxes |  | $ | 35,421 |  |  | $ | 33,594 |  |  | $ | 46,208 |

A reconciliation of the beginning and ending amount of uncertain tax positions is as follows:

|  | 2013 |  |  | 2012 |  |  | 2011 |
|  | (In Thousands) |
Balance at beginning of year |  | $ | 2,292 |  |  | $ | 709 |  |  | $ | 700 |
Additions based on tax positions related to the current year |  |  | 97 |  |  |  | 131 |  |  |  | 217 |
Additions based on tax positions of prior years |  |  | 255 |  |  |  | 1,937 |  |  |  | — |
Reductions for tax positions of prior years |  |  | (123 | ) |  |  | (485 | ) |  |  | (51 | )
Settlements |  |  | (112 | ) |  |  | — |  |  |  | (157 | )
Balance at end of year |  | $ | 2,409 |  |  | $ | 2,292 |  |  | $ | 709 |

We expect that the amount of unrecognized tax benefits may change as the result of ongoing operations, the outcomes of audits, and the expiration of statute of limitations. This change is not expected to have a significant impact on our results of operations or the financial condition. The total amount of unrecognized tax benefits that would impact the effective tax rate, if recognized, was $204,000, $236,000, and $461,000, net of federal expense, in 2013, 2012, and 2011, respectively.

We record interest related to unrecognized tax positions in interest expense and penalties in operating other expense. During 2013, 2012, and 2011, we recognized $121,000, $430,000, and $42,000, respectively, in interest and penalties associated with unrecognized tax benefits. We had approximately $585,000, and $464,000 accrued for interest and penalties at December 31, 2013 and 2012, respectively.

LSB and certain of its subsidiaries file income tax returns in the U.S. federal jurisdiction and various state jurisdictions. With few exceptions, the 2010-2012 years remain open for all purposes of examination by the U.S. Internal Revenue Service (“IRS”) and other major tax jurisdictions. We are under examination by the IRS for the tax years 2008-2010. As of December 31, 2013, the IRS has proposed certain adjustments, which we are protesting. We anticipate that the adjustments, if any, will not result in a material change to our financial position.

11. Commitments and Contingencies

Operating Leases—We lease certain PP&E under non-cancelable operating leases. Future minimum payments on operating leases with initial or remaining terms of one year or more at December 31, 2013, are as follows:

|  | Operating Leases |
2014 |  | $ | 4,451 |
2015 |  |  | 2,775 |
2016 |  |  | 1,929 |
2017 |  |  | 1,675 |
2018 |  |  | 1,421 |
Thereafter |  |  | 1,330 |
Total minimum lease payments |  | $ | 13,581 |

Expenses associated with our operating lease agreements, including month-to-month leases, were $6,401,000 in 2013, $6,830,000 in 2012, and $7,773,000 in 2011. Renewal options are available under certain of the lease agreements for various periods at approximately the existing annual rental amounts.

Purchase and Sales Commitments—We have the following significant purchase and sales commitments.

Bayer Agreement—Subsidiaries within our Chemical Business, El Dorado Nitric Company and its subsidiaries (“EDN”) and EDC, are party to an agreement (the “Bayer Agreement”) with Bayer Material Science LLC (“Bayer”). EDN operates Bayer’s nitric acid plant (the “Baytown Facility”) located within Bayer’s chemical manufacturing complex. Under the terms of the Bayer Agreement, Bayer purchases from EDN all of Bayer’s requirements for nitric acid for use in Bayer’s chemical manufacturing complex located in Baytown, Texas that provides a pass-through of certain costs plus a profit. In addition, EDN is responsible for the maintenance and operation of the Baytown Facility. If there is a change in control of EDN, Bayer has the right to terminate the Bayer Agreement upon payment of certain fees to EDN. In June 2013, the Bayer Agreement was amended, dated effective July 1, 2014, to extend the term of the agreement for an additional seven years, beginning July 1, 2014. The amendment also provides incentives to EDN for meeting certain safety, environmental, and reliability thresholds.

Anhydrous ammonia purchase agreement—During August 2012, EDC entered into an amendment to EDC’s anhydrous ammonia purchase agreement with Koch Nitrogen International Sarl (“Koch”). Under the amendment, Koch agrees to supply certain of EDC’s requirements of anhydrous ammonia through December 31, 2015. The terms of this agreement do not include minimum volumes or take-or-pay provisions.

Ammonium nitrate supply agreement—Pursuant to a long-term cost-plus supply agreement, EDC supplies Orica International Pte Ltd (“Orica”) with an annual minimum of 240,000 tons of industrial grade ammonium nitrate (“AN”) produced at our chemical production facility located in El Dorado, Arkansas (the “El Dorado Facility”) through December 2014. The agreement includes a provision for Orica to pay for product not taken. In April 2013, this agreement was amended to update and correct the specification of AN solution to be manufactured by EDC. The amendment also modified the required notice of termination from two years to one year, with the termination date to be no sooner than April 9, 2015.

UAN supply agreement – A subsidiary within our Chemical Business, Pryor Chemical Company (“PCC”), is party to a contract with Koch Nitrogen Company, LLC (“Koch Nitrogen”) under which Koch Nitrogen agrees to purchase and distribute at market prices substantially all of the urea ammonium nitrate (“UAN”) produced at the Pryor Facility through June 30, 2016, but either party has an option to terminate the agreement pursuant to the terms of the contract (PCC’s required notice of termination is three months and Koch Nitrogen’s required notice of termination is six months).

Natural gas gathering agreements – Zena owns approximately 12% working interest in certain natural gas properties but is not the operator of these properties. The operator of the natural gas wells developed on these properties has contractually agreed to deliver a minimum daily quantity of natural gas to a certain gathering and pipeline system through December 2026 to ensure capacity availability on that system. This gathering agreement effectively requires a daily minimum demand charge. As a result, Zena’s proportionate share of the annual minimum demand charges is approximately $1.8 million for the next five years and approximately $7.5 million thereafter for a total of approximately $16.5 million.

Other purchase and sales commitments—See Note 12—Derivatives, Hedges, Financial Instruments and Carbon Credits for our commitments relating to derivative contracts and carbon credits at December 31, 2013. During 2013, certain subsidiaries within the Chemical Business entered into contracts to purchase natural gas for anticipated production needs at certain of our chemical facilities. Since these contracts are considered normal purchases because they provide for the purchase of natural gas that will be delivered in quantities expected to be used over a reasonable period of time in the normal course of business and are documented as such, these contracts are exempt from the accounting and reporting requirements relating to derivatives. At December 31, 2013, our purchase commitments under these contracts were for approximately 1.6 million MMBtu of natural gas through May 2014 at the weighted-average cost of $3.47 per MMBtu ($5.6 million) and a weighted-average market value of $4.20 per MMBtu ($6.8 million). In addition, we had standby letters of credit outstanding of approximately $2.7 million at December 31, 2013. We also had deposits from customers of $5.5 million for forward sales commitments, most of which relate to our Chemical Business at December 31, 2013.

Capital Project Commitments – During 2012, EDC entered into an agreement with Weatherly Inc. for the licensing, engineering, and procurement of major manufacturing equipment for a new 65% strength nitric acid plant (“Nitric Acid Plant”) to be constructed at the El Dorado Facility. During 2013, EDC entered into various agreements with SAIC Constructors, LLC to engineer, procure and construct the Nitric Acid Plant, a nitric acid concentrator and certain support facilities at the El Dorado Facility. The estimated cost for this project is approximately $120 million, of which $48 million has been incurred and capitalized at December 31, 2013.

During 2013, a subsidiary of EDC entered into various agreements with SAIC Constructors, LLC to engineer, procure and construct an ammonia plant and certain support facilities. The estimated cost for this project ranges from $250 million to $300 million, of which $36 million has been incurred and capitalized at December 31, 2013.

Performance and Payment Bonds – We are contingently liable to sureties in respect of certain insurance bonds issued by the sureties in connection with certain contracts entered into by certain subsidiaries in the normal course of business. These insurance bonds primarily represent guarantees of future performance of our subsidiaries. As of December 31, 2013, we have agreed to indemnify the sureties for payments, up to $9.9 million, made by them in respect of such bonds. All of these insurance bonds are expected to expire or be renewed in 2014.

Universal Shelf Registration Statement—In November 2012, we filed a universal shelf registration statement on Form S-3, with the SEC. The shelf registration statement provides that we could offer and sell up to $200 million of our securities consisting of equity (common and preferred), debt (senior and subordinated), warrants and units, or a combination thereof. The shelf registration statement expires in November 2015 unless we decide to file a post effective amendment.

Employment and Severance Agreements—We have an employment agreement and severance agreements with several of our officers. The agreements, as amended, provide for annual base salaries, bonuses and other benefits commonly found in such agreements. In the event of termination of employment due to a change in control (as defined in the agreements), the agreements provide for payments aggregating $14.3 million at December 31, 2013.

Legal Matters—Following is a summary of certain legal matters involving the Company:

A. Environmental Matters

Our facilities and operations are subject to numerous federal, state and local environmental laws (“Environmental Laws”) and to other laws regarding health and safety matters (“Health Laws”). In particular, the manufacture, production and distribution of products by our Chemical Business are activities that entail environmental and public health risks and impose obligations under the Environmental Laws and the Health Laws, many of which provide for certain performance obligations, substantial fines and criminal sanctions for violations. There can be no assurance that we will not incur material costs or liabilities in complying with such laws or in paying fines or penalties for violation of such laws. The Environmental Laws and Health Laws and enforcement policies thereunder have in the past resulted, and could in the future result, in significant compliance expenses, cleanup costs (for our sites or third-party sites where our wastes were disposed of), penalties or other liabilities relating to the handling, manufacture, use, emission, discharge or disposal of hazardous or toxic materials at or from our facilities or the use or disposal of certain of its chemical products. Historically, significant expenditures have been incurred by subsidiaries within our Chemical Business in order to comply with the Environmental Laws and Health Laws and are reasonably expected to be incurred in the future. We will also be obligated to manage certain discharge water outlets and monitor groundwater contaminants at our Chemical Business facilities should we discontinue the operations of a facility. We do not operate the natural gas wells where we own an interest and compliance with Environmental Laws and Health Laws is controlled by others, with our Chemical Business being responsible for its proportionate share of the costs involved. As of December 31, 2013, our accrued liabilities for environmental matters totaled $1,234,000 relating primarily to matters discussed below. It is reasonably possible that a change in the estimate of our liability could occur in the near term. Also see discussion in Note 8 – Asset Retirement Obligations.

1. Discharge Water Matters

Each of our chemical manufacturing facilities generates process wastewater, which may include cooling tower and boiler water quality control streams, contact storm water (rain water inside the facility area that picks up contaminants) and miscellaneous spills and leaks from process equipment. The process water discharge, storm-water runoff and miscellaneous spills and leaks are governed by various permits generally issued by the respective state environmental agencies as authorized by the United States Environmental Protection Agency (“EPA”), subject to oversight by the EPA. These permits limit the type and amount of effluents that can be discharged and controls the method of such discharge. The following are discharge water matters in relation to the respective permits.

The El Dorado Facility is subject to a state National Pollutant Discharge Elimination System (“NPDES”) discharge water permit issued by the Arkansas Department of Environmental Quality (“ADEQ”). The El Dorado Facility is currently operating under an NPDES discharge water permit, which became effective in 2004 (“2004 NPDES permit”). In November 2010, a preliminary draft of a discharge water permit renewal for the El Dorado Facility, which contains more restrictive limits, was issued by the ADEQ.

EDC believes that the El Dorado Facility has generally demonstrated its ability to comply with applicable ammonia and nitrate permit limits, but has, from time to time, had difficulty demonstrating consistent compliance with the more restrictive dissolved minerals permit levels. As part of the El Dorado Facility’s long-term compliance plan, EDC has pursued a rulemaking and permit modification with the ADEQ as to the discharge requirements relating to its dissolved minerals. The ADEQ approved a rule change, but the EPA formally disapproved the rule change. In October 2011, EDC filed a lawsuit against the EPA in the United States District Court, El Dorado, Arkansas, appealing the EPA’s decision disapproving the rule change. In March 2013, the District Court affirmed the EPA’s decision. EDC has appealed the District Court’s decision. We do not believe this matter regarding meeting the permit requirements as to the dissolved minerals will continue to be an issue now that the pipeline discussed below is operational and EDC’s right to use the pipeline to dispose of its wastewater.

During 2012, EDC paid a penalty of $100,000 to settle an Administrative Complaint issued by the EPA, and thereafter handled by the United States Department of Justice (“DOJ”), relating to certain alleged violations of EDC’s 2004 NPDES permit for alleged violations through December 31, 2010. The DOJ advised that some action would be taken for alleged violations occurring after December 31, 2010. As of the date of this report, no action has been filed by the DOJ. The cost (or range of costs) cannot currently be reasonably estimated regarding this matter. Therefore, no liability has been established at December 31, 2013.

During 2013, the City of El Dorado, Arkansas (the “City”) completed the construction of a pipeline for disposal of wastewater generated by the City and by certain companies in the El Dorado area. EDC and other companies in the El Dorado area entered into a funding agreement and operating agreement with the City, pursuant to which each party agreed to contribute to the cost of construction and the annual operating costs of the pipeline for the right to use the pipeline to dispose its wastewater. EDC believes that the disposal of wastewater through this pipeline will enable EDC to comply with water discharge permit limits under current and foreseeable regulations. The City completed the construction of the pipeline and EDC began utilizing the pipeline during 2013. EDC is contractually obligated to pay a portion of the operating costs of the pipeline, which portion is estimated to be $100,000 to $150,000 annually. The initial term of the operating agreement is through December 2053.

In addition, the El Dorado Facility is currently operating under a consent administrative order (“2006 CAO”) that recognizes the presence of nitrate contamination in the shallow groundwater. The 2006 CAO required EDC to continue semiannual groundwater monitoring, to continue operation of a groundwater recovery system and to submit a human health and ecological risk assessment to the ADEQ relating to the El Dorado Facility. The final remedy for shallow groundwater contamination, should any remediation be required, will be selected pursuant to a new consent administrative order and based upon the risk assessment. The cost of any additional remediation that may be required will be determined based on the results of the investigation and risk assessment, of which cost (or range of costs) cannot currently be reasonably estimated. Therefore, no liability has been established at December 31, 2013, in connection with this matter.

2. Air Matters

In connection with a national enforcement initiative, the EPA had sent information requests to most, if not all, of the operators of nitric acid plants in the United States, including our El Dorado Facility, our chemical production facility located in Cherokee, Alabama (the “Cherokee Facility”) and the Baytown Facility operated by our subsidiary, EDN, under Section 114 of the Clean Air Act as to construction and modification activities at each of these facilities over a period of years.

During 2013, we negotiated a global agreement in principle with the EPA/DOJ to settle this matter. The agreement provides, among other things, the following:

| • |  | all of our Chemical Business’ nitric acid plants are to achieve certain emission rates within a certain time period for each plant. In order to achieve these emission rates, six of our Chemical Business’ eight nitric acid plants will require additional pollution control technology equipment to achieve the emission rates agreed upon. We have already completed necessary modifications at two of our Chemical Business’ existing nitric acid plants. The cost of the necessary pollution control equipment is estimated to range from $2.0 million to $3.0 million for each of the remaining six nitric acid plants, the cost of which will be capitalized when incurred;

| • |  | our Chemical Business will provide a reforestation mitigation project that is unrelated to our emissions or activities and will not be located at one of our plant sites, which we estimate will cost approximately $150,000 and have included this amount in our accrued liabilities for environmental matters discussed above; and

| • |  | a civil penalty will be paid by our Chemical Business in the amount of $725,000 (which includes the $100,000 civil penalty to the ODEQ discussed below), which amount is included in our accrued liabilities for environmental matters discussed above.

One of our subsidiaries, Pryor Chemical Company (“PCC”), within our Chemical Business, has been advised that the Oklahoma Department of Environmental Quality (“ODEQ”) is conducting an investigation into whether the chemical production facility located in Pryor, Oklahoma (the “Pryor Facility”) was in compliance with certain rules and regulations of the ODEQ and whether PCC’s reports of certain air emissions relating primarily to 2011 were intentionally reported incorrectly to the ODEQ. Pursuant to the request of the ODEQ, PCC submitted information and a report to the ODEQ as to the reports filed by the Pryor Facility relating to the air emissions in question. In February 2013, investigators with the ODEQ obtained documents from the Pryor Facility in connection with this investigation pursuant to a search warrant and interviewed several employees at the facility. PCC has cooperated with the ODEQ in connection with this investigation. As of December 31, 2013, we are not aware of any recommendations made or to be made by the ODEQ with respect to formal legal action to be taken or recommended as a result of this ongoing investigation. By letter dated April 19, 2013 (the “letter”), ODEQ, based on its inspection of our Pryor Facility conducted in December 2012, identified fourteen issues of alleged non-compliance and concern from the evaluation relating to federal and state air quality regulations, some of which were the subject of the ongoing investigation by ODEQ described above. PCC engaged in discussions with ODEQ and a settlement was reached to resolve the allegations identified in the letter. Three of the violations were resolved through the global settlement with the EPA/DOJ discussed above, and ODEQ agreed to resolve the remaining eleven violations by PCC paying a civil penalty for $100,000 (which amount is included in the $725,000 civil penalty discussed above) with the settlement being addressed as an addition to the global settlement discussed above. This settlement is unrelated to the pending ODEQ investigation at the Pryor Facility described above, which remains ongoing to our knowledge.

3. Other Environmental Matters

In 2002, two subsidiaries within our Chemical Business sold substantially all of their operating assets relating to a Kansas chemical facility (“Hallowell Facility”) but retained ownership of the real property. Even though we continued to own the real property, we did not assess our continuing involvement with our former Hallowell Facility to be significant and therefore accounted for the sale as discontinued operations. Our subsidiary retained the obligation to be responsible for, and perform the activities under, a previously executed consent order to investigate the surface and subsurface contamination at the real property and a corrective action strategy based on the investigation. In addition, certain of our subsidiaries agreed to indemnify the buyer of such assets for these environmental matters. Based on the assessment discussed above, we account for transactions associated with the Hallowell Facility as discontinued operations.

The successor (“Chevron”) of a prior owner of the Hallowell Facility has agreed in writing, on a nonbinding basis and within certain other limitations, to pay and has been paying one-half of the costs of the interim measures relating to this matter as approved by the Kansas Department of Environmental Quality, subject to reallocation.

Our subsidiary and Chevron are pursuing with the state of Kansas a course of long-term surface and groundwater monitoring to track the natural decline in contamination. Currently, our subsidiary and Chevron are in the process of performing additional surface and groundwater testing. We have accrued for our allocable portion of costs for the additional testing, monitoring and risk assessments that could be reasonably estimated, which is included in our accrued liabilities for environmental matters discussed above. The estimated amount is not discounted to its present value.

In addition during 2010, the Kansas Department of Health and Environment (“KDHE”) notified our subsidiary and Chevron that the Hallowell Facility has been referred to the KDHE’s Natural Resources Trustee, who is to consider and recommend restoration, replacement and/or whether to seek compensation. KDHE will consider the recommendations in its evaluation. Currently, it is unknown what damages the KDHE would claim, if any. The ultimate required remediation, if any, is unknown.

The nature and extent of a portion of the requirements are also not currently defined, and the associated costs (or range of costs) are not currently reasonably estimable. Therefore, no liability has been established at December 31, 2013, in connection with the KDHE’s Natural Resources Trustee matter.

B. Other Pending, Threatened or Settled Litigation

During April 2013, an explosion and fire occurred at the West Fertilizer Co. (“West Fertilizer”), located in West, Texas, causing death, bodily injury and substantial property damage. West Fertilizer is not owned or controlled by us, but West Fertilizer had been a customer of EDC, purchasing ammonium nitrate (“AN”) from EDC from time to time. LSB and EDC previously received letters from counsel purporting to represent subrogated insurance carriers, personal injury claimants and persons who suffered property damages informing them that their clients are conducting investigations into the cause of the explosion and fire to determine, among other things, whether AN manufactured by EDC and supplied to West Fertilizer was stored at West Fertilizer at the time of the explosion and, if so, whether such AN may have been one of the contributing factors of the explosion. Other manufacturers of AN also supplied AN to West Fertilizer. Initially, the lawsuits that had been filed named West Fertilizer and another supplier of AN as defendants. Although EDC does not believe that its product was in storage at West Fertilizer at the time of the explosion, there has been testimony in depositions taken in connection with the pending lawsuits that some of the AN products at West Fertilizer at the time of the explosion were produced by EDC. As a result, EDC and LSB have been named as defendants, together with other AN manufactures, in the case styled City of West, Texas v CF Industries, Inc., et al, in the District Court of McLennan County, Texas. Plaintiffs are alleging, among other things, that LSB and EDC were negligent in the production and inspection of fertilizer products sold to West Fertilizer resulting in death, personal injury and property damage. EDC has retained a firm specializing in cause and origin investigations, with particular experience with fertilizer facilities, to assist EDC in its own investigation. LSB and EDC have placed its liability insurance carrier on notice of this matter. Our product liability insurance policies have aggregate limits of general liability totaling $100 million, with a self-insured retention of $250,000. As of December 31, 2013, no liability has been established in connection with this matter, but we have incurred professional fees of approximately $200,000 being applied against our self-insured retention amount.

Other Claims and Legal Actions

We are also involved in various other claims and legal actions including claims for damages resulting from water leaks related to our Climate Control products and other product liability occurrences. Most of the product liability claims are covered by our general liability insurance, which generally includes a deductible of $250,000 per claim. For any claims or legal actions that we have assessed the likelihood of our liability as probable, we have recognized our estimated liability up to the applicable deductible. At December 31, 2013, our accrued general liability insurance claims were $335,000 and are included in accrued and other liabilities. It is possible that the actual future development of claims could be different from our estimates but, after consultation with legal counsel, we believe that changes in our estimates will not have a material effect on our business, financial condition, results of operations or cash flows.

12. Derivatives, Hedges, Financial Instruments and Carbon Credits

Periodically, we have three classes of contracts that are accounted for on a fair value basis, which are commodities futures/forward contracts (“commodities contracts”), foreign exchange contracts and interest rate contracts as discussed below. All of these contracts are used as economic hedges for risk management purposes but are not designated as hedging instruments. In addition as discussed below, we are issued climate reserve tonnes (“carbon credits”), of which a certain portion of the carbon credits are to be sold and the proceeds given to Bayer. The assets for carbon credits are accounted for on a fair value basis as discussed below. Also, the contractual obligations to give the related proceeds to Bayer are accounted for on a fair value basis (as discussed below) unless we enter into a firm sales commitment to sell the carbon credits as discussed in Note 1—Summary of Significant Accounting Policies. The valuations of these assets and liabilities were determined based on quoted market prices or, in instances where market quotes are not available, other valuation techniques or models used to estimate fair values.

12. Derivatives, Hedges, Financial Instruments and Carbon Credits (continued)

The valuations of contracts classified as Level 1 are based on quoted prices in active markets for identical contracts. The valuations of contracts classified as Level 2 are based on quoted prices for similar contracts and valuation inputs other than quoted prices that are observable for these contracts. At December 31, 2013 and 2012, the valuations of contracts classified as Level 2 related to interest rate swap contracts. For interest rate swap contracts, we utilize valuation software and market data from a third-party provider. These contracts are valued using a discounted cash flow model that calculates the present value of future cash flows pursuant to the terms of the contracts and using market information for forward interest-rate yield curves. At December 31, 2013, the valuation inputs included the contractual weighted-average pay rate of 3.23% and the estimated market weighted-average receive rate of 0.54%. No valuation input adjustments were considered necessary relating to nonperformance risk for the contracts.

The valuations of assets and liabilities classified as Level 3 are based on prices or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement. At December 31, 2013 and 2012, the valuations ($1.00 and $0.50 per carbon credit, respectively) of the carbon credits and the contractual obligations associated with these carbon credits are classified as Level 3 and are based on the range of ask/bid prices obtained from a broker adjusted downward due to minimal market volume activity. The valuations are using undiscounted cash flows based on management’s assumption that the carbon credits would be sold and the associated contractual obligations would be extinguished in the near term. In addition, no valuation input adjustments were considered necessary relating to nonperformance risk for the carbon credits and associated contractual obligations.

Commodities Contracts

Raw materials for use in our manufacturing processes include copper used by our Climate Control Business and anhydrous ammonia and natural gas used by our Chemical Business. As part of our raw material price risk management, we periodically enter into futures/forward contracts for these materials, which contracts may be required to be accounted for on a mark-to-market basis. At December 31, 2013, we did not have any futures/forward copper contracts. At December 31, 2012, our futures/forward copper contracts were for 625,000 pounds of copper through May 2013 at a weighted-average cost of $3.53 per pound. At December 31, 2013, our futures/forward natural gas contracts were for 1,530,000 MMBtu of natural gas through October 2014 at a weighted-average cost of $3.98 per MMBtu. At December 31, 2012, we did not have any futures/forward natural gas contracts requiring mark-to-market accounting. The cash flows relating to these contracts are included in cash flows from continuing operating activities.

Foreign Exchange Contracts

One of our business operations purchases industrial machinery and related components from vendors outside of the United States. As part of our foreign currency risk management, we periodically enter into foreign exchange contracts, which set the U.S. Dollar/Euro exchange rates. These contracts are free-standing derivatives and are accounted for on a mark-to-market basis. At December 31, 2013 and 2012, we did not have any foreign exchange contracts. The cash flows relating to these contracts are included in cash flows from continuing operating activities.

Interest Rate Contracts

As part of our interest rate risk management, we periodically purchase and/or enter into various interest rate contracts. In April 2008, we entered into an interest rate swap at no cost, which set a fixed three-month LIBOR rate of 3.24% on $25 million and matured in April 2012. In September 2008, we acquired an interest rate swap at a cost basis of $0.4 million, which set a fixed three-month LIBOR rate of 3.595% on $25 million and matured in April 2012.

In February 2011, we entered into an interest rate swap at no cost, which sets a fixed three-month LIBOR rate of 3.23% on a declining balance (from $23.8 million to $18.8 million) for the period beginning in April 2012 through March 2016. This contract is a free-standing derivative and is accounted for on a mark-to-market basis.

During each of the three years ended December 31, 2013, no cash flows occurred relating to the purchase or sale of interest rate contracts. The cash flows associated with the interest rate swap payments are included in cash flows from continuing operating activities.

Carbon Credits and Associated Contractual Obligation

Periodically, we are issued carbon credits by the Climate Action Reserve in relation to a greenhouse gas reduction project (“Project”) performed at the Baytown Facility. Pursuant to the terms of the agreement with Bayer, a certain portion of the carbon credits are to be used to recover the costs of the Project, and any balance thereafter to be allocated between Bayer and EDN. We have no obligation to reimburse Bayer for their costs associated with the Project, except through the transfer or sale of the carbon credits when such credits are issued to us. The assets for carbon credits are accounted for on a fair value basis and the contractual obligations associated with these carbon credits are also accounted for on a fair value basis (unless we enter into a sales commitment to sell the carbon credits). At December 31, 2013, we had approximately 1,284,000 carbon credits (a minimal amount at December 31, 2012), all of which were subject to contractual obligations. The cash flows associated with the carbon credits and the associated contractual obligations are included in cash flows from continuing investing activities.

At December 31, 2013 and 2012, we did not have any financial instruments with fair values significantly different from their carrying amounts, except for the Senior Secured Notes at December 31, 2013. The estimated fair value of the Senior Secured Notes exceeded the carrying value by approximately $20 million. The valuation is classified as Level 2 and is based on the range of ask/bid prices (104.5 to 104.9) for these notes but are currently traded in a limited and low volume market since these notes have not yet been registered. The valuations of our other long-term debt agreements are classified as Level 3 and are based on valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement. The fair value measurement of our long-term debt agreements are valued using a discounted cash flow model that calculates the present value of future cash flows pursuant to the terms of the debt agreements and applies estimated current market interest rates. The estimated current market interest rates are based primarily on interest rates currently being offered on borrowings of similar amounts and terms. In addition, no valuation input adjustments were considered necessary relating to nonperformance risk for our debt agreements. The fair value of financial instruments is not indicative of the overall fair value of our assets and liabilities since financial instruments do not include all assets, including intangibles, and all liabilities. Also see discussions concerning certain assets and liabilities initially accounted for on a fair value basis under Note 8 – Asset Retirement Obligations.

13. Stockholders’ Equity

2008 Stock Incentive Plan—During 2008, our stockholders approved an Incentive Stock Plan (the “2008 Plan”). The number of shares of our common stock available for issuance under the 2008 Plan was 1,000,000 shares, subject to adjustment. Under the 2008 Plan, awards may be made to any employee, officer or director of the Company and its affiliated companies. An award may also be granted to any consultant, agent, advisor or independent contractor for bona fide services rendered to the Company or any affiliate (as defined in the 2008 Plan), subject to certain conditions. The 2008 Plan is being administered by the compensation and stock option committee (the “Committee”) of our board of directors.

Our board of directors or the Committee may amend the 2008 Plan, except that if any applicable statute, rule or regulation requires shareholder approval with respect to any amendment of the 2008 Plan, then to the extent so required, shareholder approval will be obtained. Shareholder approval will also be obtained for any amendment that would increase the number of shares stated as available for issuance under the 2008 Plan. Unless sooner terminated by our board of directors, the 2008 Plan expires on June 5, 2018.

The following may be granted by the Committee under the 2008 Plan:

Stock Options—The Committee may grant either incentive stock options or non-qualified stock options. The Committee sets option exercise prices and terms, except that the exercise price of a stock option may be no less than 100% of the fair market value, as defined in the 2008 Plan, of the shares on the date of grant. At the time of grant, the Committee will have sole discretion in determining when stock options are exercisable and when they expire, except that the term of a stock option cannot exceed 10 years.

Stock Appreciation Rights (“SARs”)—The Committee may grant SARs as a right in tandem with the number of shares underlying stock options granted under the 2008 Plan or on a stand-alone basis. SARs are the right to receive payment per share of the SAR exercised in stock or in cash equal to the excess of the share’s fair market value, as defined in the 2008 Plan, on the date of exercise over its fair market value on the date the SAR was granted. Exercise of a SAR issued in tandem with stock options will result in the reduction of the number of shares underlying the related stock option to the extent of the SAR exercise.

Stock Awards, Restricted Stock, Restricted Stock Units, and Other Awards—The Committee may grant awards of restricted stock, restricted stock units, and other stock and cash-based awards, which may include the payment of stock in lieu of cash (including cash payable under other incentive or bonus programs) or the payment of cash (which may or may not be based on the price of our common stock).

Outside Directors Stock Option Plan—In addition to the 2008 Plan discussed above, we have an Outside Directors Stock Option Plan (the “Outside Director Plan”). The Outside Director Plan authorizes the grant of non-qualified stock options to each member of our board of directors who is not an officer or employee of LSB or its subsidiaries. The Outside Director Plan

also provides that each outside director may elect to receive all or any portion of his or her director fee for services rendered as a director of LSB in shares of LSB’s common stock, provided that the outside director elects to receive shares in payment of his or her director fee each calendar quarter. The maximum number of shares that may be issued, or for which options may be granted, under the Outside Director Plan is 400,000 of which 280,000 were available for issuance, or grant of options, at December 31, 2013.

Stock-Based Compensation—During 2013 and 2012, the Committee did not grant any awards under the 2008 Plan. During 2011, the Committee approved the grants under the 2008 Plan of 249,000 shares of qualified stock options (the “2011 Qualified Options”) to certain employees and our board of directors (with the recipient abstaining) approved the grant of 5,000 shares of non-qualified stock options (“2011 Non-Qualified Options”) to one of our outside directors. The exercise price of the 2011 Qualified and Non-Qualified Options was equal to the market value of our common stock at the date of grant. The 2011 Qualified and Non-Qualified Options vest at the end of each one-year period at the rate of 16.5% per year for the first five years and the remaining unvested options will vest at the end of the sixth year. Pursuant to the terms of the 2011 Non-Qualified Options, if a termination event occurs, as defined, the non-vested 2011 Non-Qualified Options will become fully vested and exercisable for a period of one year from the date of the termination event. Excluding the non-qualified stock options relating to a termination event, the 2011 Qualified and Non-Qualified Options expire in 2021. The fair value for the 2011 Qualified and Non-Qualified Options was estimated, using an option pricing model, as of the date of the grant, which date was also the service inception date.

The fair value for the 2011 Qualified and Non-Qualified Options was estimated using a Black-Scholes-Merton option pricing model with the following assumptions:

| • |  | risk-free interest rate based on an U.S. Treasury zero-coupon issue with a term approximating the estimated expected life as of the grant date;

| • |  | a dividend yield based on historical data;

| • |  | volatility factors of the expected market price of our common stock based on historical volatility of our common stock primarily over approximately six years from the date of grant; and

| • |  | a weighted-average expected life of the options based on the historical exercise behavior of these employees and outside director, if applicable.

The following table summarizes information about these granted stock options:

|  | 2013 |  |  | 2012 |  |  | 2011 |
Weighted-average risk-free interest rate |  |  | N/A |  |  |  | N/A |  |  |  | 1.21 | %

Qualified Stock Option Plans—At December 31, 2013, we have options outstanding under a 1998 Stock Option Plan (“1998 Plan”) and the 2008 Plan as discussed above. The 1998 Plan has expired, and accordingly, no additional options may be

granted from the 1998 Plan. Options granted prior to the expiration of this plan continue to remain valid thereafter in accordance with their terms. The exercise price of the outstanding options granted under the 1998 and 2008 Plans was equal to the market value of our common stock at the date of grant.

Debt Conversion into Common Stock—During 2011, the remaining $26.9 million of the 5.5% convertible debentures (“2007 Debentures”) were converted into 979,160 shares of LSB common stock including the portion of 2007 debentures held by Jack E. Golsen (“Golsen”), our chairman of the board and chief executive officer (“CEO”), members of his immediate family, entities owned by them and trusts for which they possess voting or dispositive power as trustee (collectively, the “Golsen Group”) as discussed in Note 19-Related Party Transactions. In addition for financial reporting purposes, one of the conversion transactions with an unrelated third party was considered an induced conversion.

Preferred Share Rights Plan—On January 5, 2009, a renewed shareholder rights plan became effective upon the expiration of our previous shareholder rights plan. The rights plan will impact a potential acquirer unless the acquirer negotiates with our board of directors and the board of directors approves the transaction. Pursuant to the renewed plan, one preferred share purchase right (a “Right”) is attached to each currently outstanding or subsequently issued share of our common stock. Prior to becoming exercisable, the Rights trade together with our common stock. In general, if a person or group acquires or announces a tender or exchange offer for 15% or more of our common stock (except for the Golsen Group and certain other limited excluded persons), then the Rights become exercisable. Each Right entitles the holder (other than the person or group that triggers the Rights being exercisable) to purchase from us one one-hundredth of a share of Series 4 Junior Participating Preferred Stock, no par value (the “Preferred Stock”), at an exercise price of $47.75 per one one-hundredth of a share, subject to adjustment. If a person or group acquires 15% or more of our common stock, each Right will entitle the holder (other than the person or group that triggered the Rights being exercisable) to purchase shares of our common stock (or, in certain circumstances, cash or other securities) having a market value of twice the exercise price of a Right at such time. Under certain circumstances, each Right will entitle the holder (other than the person or group that triggered the Rights being exercisable) to purchase the common stock of the acquirer having a market value of twice the exercise price of a Right at such time. In addition, under certain circumstances, our board of directors may exchange each Right (other than those held by the acquirer) for one share of our common stock, subject to adjustment. Our board of directors may redeem the Rights at a price of $0.01 per Right generally at any time before 10 days after the Rights become exercisable. Our board of directors may exchange all or part of the Rights (except to the person or group that triggered the Rights being exercisable) for our common stock at an exchange ratio of one common share per Right until the person triggering the Right becomes the beneficial owner of 50% or more of our common stock.

15. Executive Benefit Agreements and Employee Savings Plans

We are party to various individual benefit agreements (“1992 Agreements”) and death benefit agreements (“1981 Agreements”) with certain key executives and a death benefit agreement (“2005 Agreement”) with our CEO. The 1992 Agreements provide for annual benefit payments for life (in addition to salary) payable in monthly installments when the employee reaches age 65. In addition, should the executive die prior to attaining the age of 65, we will pay the beneficiary named in the agreement a monthly amount as specified in the agreement over a ten-year period. These benefits are forfeited if the respective executive’s employment is terminated prior to age 65 for any reason other than death. The 1992 Agreements may be terminated by the Company at any time and for any reason prior to the death of the employee.

The 1981 Agreements provide for death benefits should the executive die while employed. Upon such of an event, we will pay the beneficiary named in the agreement a monthly amount as specified in the agreement over a ten-year period. These benefits are forfeited if the respective executive’s employment is terminated for any reason prior to death. The 1981 Agreements may be terminated by the Company at any time and for any reason prior to the death of the employee.

The 2005 Agreement provides that, upon our CEO’s death, we will pay to our CEO’s designated beneficiary, a lump-sum payment of $2,500,000 to be funded from the net proceeds received by us under certain life insurance policies on our CEO’s life that are owned by us. We are obligated to keep in existence life insurance policies with a total face amount of no less than $2,500,000 of the stated death benefit. The benefit under the 2005 Agreement is not contingent upon continued employment and may be amended at any time by written agreement executed by the CEO and the Company.

16. Property and Business Interruption Insurance Claims and Recoveries

El Dorado Facility

On May 15, 2012, the El Dorado Facility suffered significant damage when a reactor in its 98% strength nitric acid plant (“DSN plant”) exploded. No employees or individuals in the surrounding area were seriously injured as a result of the explosion. In addition, several other plants and infrastructure within the El Dorado Facility sustained various degrees of damage. Our insurance policy provided for repair or replacement cost coverage relating to property damage with a $1.0 million deductible and provided for business interruption coverage for certain lost profits and extra expense with a 30-day waiting period. We concluded that due to the extensive damage, the DSN plant should not be repaired but should be replaced with a new 65% strength nitric acid plant and a separate nitric acid concentrator.

Based upon our assessment that it was probable that the amount of coverage for property damages would exceed our property loss deductible, the net book value of the damaged property and other recoverable costs incurred through the period of the claims, we recorded an insurance claim receivable relating to this event, which offset the loss on disposal of the damaged property and certain repairs and clean-up costs incurred (“recoverable costs”).

In October 2013, we settled these claims with our insurance carriers for the aggregate amount of $113 million, of which $60 million had been paid to us prior to the conclusion of these claims and the remaining $53 million was paid to us during October and November of 2013. For financial reporting purposes, we allocated $90.7 million to our property insurance claim and $22.3 million to our business interruption claim primarily based on negotiations with our insurance carriers concerning our claims.

The $90.7 million allocated to the property insurance claim was partially applied against the recoverable costs totaling $24.7 million. The insurance recovery in excess of the recoverable costs of $66.0 million was recognized as property insurance recoveries in excess of losses incurred in 2013.

The insurance recovery of $22.3 million allocated to the business interruption claim was recognized as a reduction to cost of sales ($15.0 million in 2013 and $7.3 million in 2012) consisting of recoverable costs (primarily relating to additional expenses associated with purchased product sold to our customers while certain of our nitric and sulfuric acid plants were being repaired) and certain lost profits.

Cherokee Facility

On November 13, 2012, a pipe ruptured within our Cherokee Facility causing damage primarily to the heat exchanger portion of its ammonia plant. No serious injuries or environmental impact resulted from the pipe rupture. As a result of the damage, the Cherokee Facility could only produce, on a limited basis, nitric acid and AN solution from purchased ammonia until the repairs were completed. Our insurance policy provided, for the policy period covering this claim, for repair or replacement cost coverage relating to property damage with a $2.5 million deductible and provided for business interruption coverage for certain lost profits and extra expense with a 30-day waiting period. As a result of this event, a notice of insurance claims for property damage and business interruption was filed with the insurance carriers.

Based upon our assessment that it was probable that the amount of coverage for property damages would exceed our property loss deductible, the net book value of the damaged property and other recoverable costs incurred, we recorded an insurance claim receivable relating to this event, which offset the loss on the disposal of the damaged property and other recoverable costs incurred.

As of December 31, 2013, our insurance carriers approved and funded advance payments relating to our business interruption claim totaling $15 million. We received correspondence associated with the approval of these payments, which stated that our insurance carriers are still investigating the circumstances surrounding this event (including the cause of this event, scope of our losses and support for our claim) under a reservation of rights.

16. Property and Business Interruption Insurance Claims and Recoveries (continued)

The business interruption insurance recovery of $15 million was applied against recoverable costs (primarily relating to additional expenses associated with purchased product sold or used in products sold to our customers while our facility was being repaired) totaling $13.6 million as a reduction to cost of sales in 2013. The insurance recovery in excess of recoverable costs of $1.4 million was deferred (included in deferred gain on insurance recoveries at December 31, 2013) since this amount relates to lost profits, which is considered a gain contingency. The deferred portion of this recovery, and any additional recoveries, will be recognized when, realized or realizable and earned.

As of December 31, 2013, the balance of the insurance claim receivable, included in accounts receivable, relating to this event was $1.9 million, consisting of recoverable costs associated with our property insurance claim. See additional information regarding the conclusion of insurance claims relating to this event discussed under Note 21-Subsequent Events.

Pryor Facility

In June 2010, a pipe failure in the primary reformer of the ammonia plant at the Pryor Facility resulted in a fire that damaged the ammonia plant. The fire was immediately extinguished and there were no injuries. As a result of this damage, the Pryor Facility was unable to produce anhydrous ammonia or UAN during substantially all of third quarter of 2010. Our insurance policy provided, for the policy period covering this claim, for business interruption coverage for certain lost profits and extra expense with a 30-day waiting period. Therefore, we filed an insurance claim for business interruption. During 2011, we recognized an insurance recovery of $8.6 million relating to this business interruption claim, which was recorded as a reduction to cost of sales. We do not have any remaining insurance claims associated with our business interruption coverage relating to this event.

18. Segment Information

Factors Used by Management to Identify the Enterprise’s Reportable Segments and Measurement of Segment Income or Loss and Segment Assets

We have three operating segments (business segments) but only two reportable segments: the Chemical Business and the Climate Control Business. Our reportable segments are based on business units that offer similar products and services. The reportable segments are each managed separately because they manufacture and distribute distinct products with different production processes.

We evaluate performance and allocate resources based on operating income or loss. The accounting policies of the reportable segments are the same as those described in the summary of significant accounting policies.

Description of Each Reportable Segment

Chemical Business—The Chemical Business segment primarily manufactures and sells:

| • |  | anhydrous ammonia, fertilizer grade AN, UAN, and AN ammonia solution for agricultural applications,

| • |  | high purity and commercial grade anhydrous ammonia, high purity AN, sulfuric acids, concentrated, blended and regular nitric acid, mixed nitrating acids, carbon dioxide, and diesel exhaust fluid for industrial applications, and

| • |  | industrial grade AN and solutions for the mining industry.

Our chemical production facilities are located in El Dorado, Arkansas; Cherokee, Alabama; Pryor, Oklahoma; and Baytown, Texas. Sales to customers of this segment primarily include farmers, ranchers, fertilizer dealers and distributors primarily in the ranch land and grain production markets in the United States; industrial users of acids throughout the United States and parts of Canada; and explosive manufacturers in the United States.

During 2012 and 2013, our Chemical Business encountered a number of significant issues including an explosion in one of our nitric acid plants at the El Dorado Facility in May 2012, a pipe rupture that damaged the ammonia plant at the Cherokee Facility in November 2012 and numerous mechanical issues at the Pryor Facility during 2012 and 2013, all resulting in lost production and causing an adverse effect on 2012 and 2013 sales and operating income. Also see Note 16 – Property and Business Interruption Insurance Claims and Recoveries and Note 21 – Subsequent Events.

In October 2012 and August 2013, a subsidiary within our Chemical Business acquired working interests in certain natural gas properties. Since our Chemical Business purchases a significant amount of natural gas as a feedstock for the production of anhydrous ammonia, management considers these acquisitions as economic hedges against a portion of a potential rise in natural gas prices in the future for a portion of our future natural gas production requirements. We report the working interests as part of the Chemical Business reportable segment. All of our natural gas producing activities are within the United States (in Pennsylvania).

As of December 31, 2013, our Chemical Business employed 530 persons, with 156 represented by unions under agreements, which will expire in November of 2016 through October of 2018.

Climate Control Business—The Climate Control Business segment manufactures and sells the following variety of heating, ventilation, and air conditioning (“HVAC”) products:

| • |  | geothermal and water source heat pumps,

| • |  | hydronic fan coils, and

| • |  | other HVAC products including large custom air handlers, modular geothermal and other chillers and other products and services.

These HVAC products are primarily for use in commercial/institutional and residential new building construction, renovation of existing buildings and replacement of existing systems. Our various facilities located in Oklahoma City comprise substantially all of the Climate Control segment’s operations. Sales to customers of this segment primarily include original equipment manufacturers, contractors and independent sales representatives located throughout the world.

18. Segment Information (continued)

Our chief operating decision makers use operating income by business segment for purposes of making decisions that include resource allocations and performance evaluations. Operating income by business segment represents gross profit by business segment less SG&A incurred by each business segment plus other income and other expense earned/incurred by each business segment before general corporate expenses. General corporate expenses consist of SG&A, other income and other expense that are not allocated to one of our business segments.

Identifiable assets by business segment are those assets used in the operations of each business. Corporate assets are those principally owned by LSB or by subsidiaries not involved in the three business segments.

All net sales and long-lived assets relate to domestic operations for the periods presented.

Net sales to unaffiliated customers are to U.S. customers except foreign export sales as follows:

Geographic Area |  | 2013 |  |  | 2012 |  |  | 2011 |
|  | (In Thousands) |
Canada |  | $ | 19,976 |  |  | $ | 21,079 |  |  | $ | 23,765 |

|  | $ | 34,154 |  |  | $ | 32,170 |  |  | $ | 36,215 |

In general, foreign export sales are attributed based upon the location of the customer.

Major Customer

Net sales to one customer, Orica, of our Chemical Business segment represented approximately 6%, 9% and 11% of our total net sales for 2013, 2012 and 2011, respectively. See discussion concerning the supply agreement in Note 11 – Commitments and Contingencies.

21. Subsequent Events

Conclusion of Insurance Claims-Cherokee Facility-As discussed in Note 16, we filed an insurance claim for losses and damages in connection with a November 2012 pipe rupture within the Cherokee Facility. During 2013, our insurance carriers advanced $15 million on the insurance claim. In January 2014, we settled the claim with our insurance carriers for the aggregate amount of approximately $43.5 million (of which approximately $36.5 million relates to the business interruption claim), comprised of $15 million previously paid to us and $28.5 million paid to us in January 2014. The $43.5 million settlement amount is net of our $2.5 million property insurance deductible. As a result, an insurance recovery of approximately $28 million will be recognized as income associated with this settlement in the first quarter of 2014.

Downtime at the Pryor Facility – As discussed in Note 18 – Segment Information, the Pryor Facility has encountered numerous mechanical issues during 2012 and 2013. In January 2014, the Pryor Facility suspended production as the result of continued mechanical issues.
