PAR T 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 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 for the agricultural, industrial, and mining markets that it produces 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”).

| · | Climate Control Business manufactures and sells a broad range of HVAC products that includes water source and geothermal heat pumps, hydronic fan coils, large custom air handlers, modular geothermal and other chillers, and other related products and services. These products are primarily used 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 Reportable Business Segments

Chemical Business

General

Our Chemical Business supplies chemical products to some of the world’s leading chemical and industrial companies. Focusing on specific geographic areas, we utilize freight and distribution advantages over many of our competitors. We also believe our Chemical Business has established leading regional market positions.

Our Chemical Business manufactures products for three principal markets:

| · | ammonia, fertilizer grade ammonium nitrate (“AN”), urea ammonia nitrate (“UAN”), and AN solution for agricultural applications,

| · | high purity and commercial grade 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 agricultural products comprise 49% of our chemical sales. We sell most of our agricultural products at the current spot market price in effect at the time of shipment, although we periodically enter into forward sales commitments for some of these products. Sales of our industrial and mining products are generally made to customers 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. 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.

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

|  | 2015 |  |  | 2014 |  |  | 2013 |
Percentage of net sales of the Chemical Business: |  |  |  |  |  |  |  |  |  |  |  |

Market Conditions - Chemical Business

As discussed in more detail under “Key Industry Factors” of “Management’s Discussion and Analysis of Financial Condition and Results of Operations” (“MD&A”) contained in this report, agricultural fertilizer demand is a significant driver of our sales volumes. This demand is driven by the number of acres planted of crops, principally corn, requiring fertilizer to enhance yield. Corn prices affect the number of acres of corn planted in a given year, and the number of acres planted will drive nitrogen fertilizer consumption, likely driving ammonia, UAN and urea prices. Weather also has an impact on fertilizer application and consumption. The 2014 corn crop produced record production and yields per acre that resulted in significantly higher year-end stock to use ratios compared to the last ten years average. This increase resulted in 2 million fewer acres of corn planted in 2015, approximately 88 million acres down from 91 million acres, which in turn, resulted in the 2015 corn crop being down 53 million bushels compared to 2014’s record year. While world stock to use ratios are up, current U.S. stock to use ratios, while having increased over the past five years, remain in line with historical levels. Estimates for 2016 are an increase of 2 million acres of corn being planted resulting in a total of over 90 million acres planted. As a result, the fundamentals are positive for nitrogen fertilizers that are necessary to enhance the yield per acre for most major crops.

However, there was an abbreviated 2015 fall fertilizer application season, resulting from unusually wet weather, and there was an increase in fertilizer inventories. This increase in inventories had a significant negative effect on the current pricing of fertilizers, reducing overall selling prices. However, it is anticipated that the 2016 spring application of fertilizer will require additional fertilizer to be applied to make up for the shortage of fertilizer applied in the fall. The expected increase in fertilizer applications when combined with the additional acres to be planted in 2016, may be catalysts for selling prices to increase from current levels.

In the industrial and mining markets, sales volumes are driven by general economic conditions, energy prices, and our contractual arrangements with certain large customers. As reported by the U.S. Energy Information Administration (“EIA”), annual coal production for 2015 is estimated to be down 11% from the prior year with a further reduction of 6% estimated for 2016. U.S. coal production is being negatively impacted by low natural gas prices among other things. In addition, other mining operations are being negatively impacted by commodity price decreases.

As natural gas is the basic feedstock for the production of ammonia, North American ammonia producers have a natural gas cost advantage due to the current historically low price of natural gas and it is expected that the price of natural gas will remain relatively low for the foreseeable future. Based upon most estimates, including Blue Johnson & Associates, Inc., the U.S. imports approximately 32% of its annual ammonia consumption. However, 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.

One additional factor that is expected to affect the overall nitrogen market is the number of nitrogen expansion projects under construction in the U.S, including our expansion project at our El Dorado Facility (the “El Dorado Expansion”) discussed under “MD&A - Liquidity and Capital Resources.” These expansion projects are expected to increase production capacity in total by approximately 5 million to 6 million tons of ammonia annually. All of these projects are currently scheduled to begin producing ammonia and other upgraded nitrogen products by early 2018. In addition, there are a number of other announced green field projects where construction has not yet begun and, if they were to be completed, the production would not begin until 2019 at the earliest. The amount and timing of additional nitrogen capacity could have a negative effect on prices of nitrogen-based products in the future.

Agricultural Products

Our Chemical Business produces UAN, agricultural grade AN, and 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 delivering to distributors on the Tennessee and Ohio rivers by barge, and by delivering to certain Western States by rail.

In November 2015, one of our subsidiaries within our Chemical Business, El Dorado Chemical Company (“EDC”) and Koch Fertilizer entered into an ammonia purchase and sale agreement under which Koch Fertilizer agrees to purchase, with minimum purchase requirements, the ammonia that is in excess of El Dorado’s internal needs as the result of the El Dorado Expansion.

Our agricultural business establishes long-term relationships with wholesale agricultural distributors and retailers and also sells directly to agricultural end-users through our network of 11 wholesale and retail distribution centers. In addition, our Chemical Business has an agreement with a third-party purchaser to buy, at market prices, substantially all of the UAN produced at the Pryor Facility. The term of the agreement runs through June 2016, but may be terminated earlier by either party pursuant to the terms of the agreement. We intend to renew this contract or one similar with this third-party purchaser or another third-party purchaser.

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 and 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 most technologically advanced nitric acid manufacturing units in the U.S. The majority of the Baytown Facility’s production is sold to Covestro AG, (formerly Bayer MaterialScience, LLC) pursuant to a long-term contract that provides for a pass-through of certain costs, including the ammonia costs, plus a fixed dollar profit and performance incentives (the” Covestro Agreement”). The term of the Covestro Agreement runs until June 2021 with options for renewal with Covestro’s consent.

Our industrial business competes based upon service, price and 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 mining business manufactures industrial grade AN and 83% AN solution. Until April 2015, El Dorado Chemical Company (“EDC”), a subsidiary within our Chemical Business supplied Orica International Pte Ltd (“Orica”) with an annual minimum of 240,000 tons of industrial grade AN pursuant to a cost plus a fixed dollar amount of profit supply agreement. The agreement with Orica (the “Orica Agreement”) also included an exclusivity arrangement that provided that EDC would not sell industrial grade AN to the commercial explosives market in the U.S. during the term of the agreement and that Orica would market EDC’s industrial grade AN to the U.S. commercial explosives market in North America during the term of the agreement. The agreement with Orica expired on April 9, 2015 and we began selling Low Density Ammonium Nitrate Prills (“LDAN”) directly to explosive distributors, mining companies and aggregate companies who sell into the coal mining metals mining and construction industries. However, we are currently disadvantaged compared to our competitors since we are purchasing ammonia to produce AN and AN solution, making us a high cost producer. This will continue until the construction of the ammonia plant at the El Dorado Facility is completed and begins production as we have signed contracts with customers that, beginning in 2016, provide for the sale of LDAN for approximately 150,000 tons per year under various natural gas cost plus a fixed dollar amount pricing arrangements. With the recent downturn in the mining industry, we are unsure if we will reach these sales volumes. Unlike the Orica Agreement, which contained take-or-pay provisions, only certain of these contracts include minimum annual volume levels with penalty payments if minimum volumes are not met. We expect that if these contracted annual volumes are purchased, they should supplant a majority of the previously contracted volume under the Orica Agreement. However, if customers do not purchase at minimum volume levels we will likely have unutilized capacity of LDAN.

For comparison purposes, the following table summarizes net sales to Orica:

|  | 2015 |  |  | 2014 |  |  | 2013 |
Net sales to Orica as a percentage of: |  |  |  |  |  |  |  |  |  |  |  |
Net sales of the Chemical Business |  |  | 4 | % |  |  | 8 | % |  |  | 11 | %
LSB's consolidated net sales |  |  | 2 | % |  |  | 5 | % |  |  | 6 | %

For 2015, 2014 and 2013, net sales to Orica above included approximately $3 million, $15 million and $12 million, respectively, for fixed overhead costs and gross profit for tons not taken by Orica, pursuant to the terms of the Orica Agreement.

Dependence on Limited Number of Customers - Chemical Business

Historically, our Chemical Business has relied on a limited number of customers as discussed in our risk factors under Item 1A included in this report.

5

Raw Materials - Chemical Business

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

Purchased ammonia currently is the raw material feedstock for all of the El Dorado Facility’s production of nitrogen products. Although ammonia is produced from natural gas, the price does not necessarily follow the spot price of natural gas in the U.S. Ammonia is an internationally traded commodity and the relative price is set in the world market while natural gas is primarily a domestically traded commodity. Currently, the ammonia supply to the El Dorado Facility is transported from the Gulf of Mexico by pipeline. Under the current agreement with its principal supplier of ammonia, EDC will have the ability to purchase a majority of its ammonia requirements through the earlier of December 31, 2016 or the date on which the new ammonia plant comes on stream. We believe that we can obtain ammonia from other sources in the event of an interruption of service under the above-referenced contract including from our company owned Pryor and Cherokee Facilities.

The El Dorado Expansion includes expanding our nitrogen fertilizer operations at the El Dorado Facility with the addition of a 1,150 ton per day (approximately 375,000 tons per year) ammonia plant, which we believe under normal conditions will allow us to produce enough ammonia to eliminate our external ammonia purchase requirements and should provide us with approximately 150,000 tons per year of additional ammonia available for sale or to upgrade into other products. This expansion is anticipated to be operational early in the second quarter of 2016 with full production levels being achieved during the second half of 2016. Once the expansion is complete, our annual natural gas requirements for this facility will be approximately 13 million MMBtu of natural gas per year.

Natural gas is the primary raw material for producing ammonia, UAN and other products at the Cherokee and Pryor Facilities. Under normal circumstances when running at a full year production schedule, the Cherokee Facility would purchase approximately 6 million MMBtu of natural gas per year in order to produce approximately 175,000 tons of ammonia and the Pryor Facility would purchase approximately 7 million MMBtu of natural gas to produce approximately 215,000 tons of ammonia.

The Cherokee and Pryor Facilities’ natural gas feedstock requirements are generally purchased at spot market price as will the natural gas feedstock requirements of the El Dorado Facility when its ammonia plant is in production. Periodically, we enter into firm purchase commitments and/or futures/forward contracts to lock in the cost of certain of the expected natural gas requirements. For 2016 we have forward purchase commitments of natural gas for approximately 3 million MMBtus for our Cherokee Facility, approximately 2 million MMBtus for our Pryor Facility and approximately 2 million MMBtus for our El Dorado Facility at an average cost of $2.76 per MMBtu. This represents approximately 30% of our exposed natural gas usage at each facility for 2016.

The Baytown Facility normally purchases approximately 135,000 tons of ammonia per year. Under the Covestro Agreement, there is a pass-through of certain costs, including the ammonia costs.

In addition, Zena Energy, L.L.C., a subsidiary within our Chemical Business owns certain natural gas working interests in natural gas properties located in the Marcellus Shale Formation in the state of Pennsylvania. Since our Chemical Business purchases a significant amount of natural gas as a feedstock for the production of ammonia, management considers these working interests as an economic hedge against a potential rise in natural gas prices. We report the working interests as part of the Chemical Business reportable segment.

See further discussion relating to the outlook for the Chemical Business under “Key Industry Factors” in our MD&A contained in this report.

Strategy - Chemical Business

Our Chemical Business pursues a strategy of balancing the sale of product as fertilizer into the agriculture markets at spot prices and developing industrial and mining customers that purchase substantial quantities of products, primarily under contractual obligations and/or pricing arrangements that provide for the pass through of raw material and other manufacturing costs. We believe that this product and market diversification strategy allows us to have consistent levels of production and helps mitigate the volatility risk inherent in the prices of our raw material feedstocks and/or the changes in demand for our products. For 2015, approximately 50% of the Chemical Business’ sales were to the industrial and mining markets and approximately 49% of our Chemical Business 2015 sales were to the agricultural markets, primarily at the market price at the time of sale.

The strategy of developing industrial and mining customers is to moderate the risk inherent in the agricultural markets where spot sales prices of our agricultural products may not have a correlation to the ammonia and natural gas feedstock costs but rather reflect market conditions for like and competing nitrogen sources. This volatility of sales pricing in our agricultural products can compromise our ability to recover our full cost to produce the product in this market. Additionally, the lack of sufficient non-seasonal agricultural sales volume to operate our manufacturing facilities at optimum levels can preclude the Chemical Business from

6

balancing production and storage capabilities. 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 Additions” of our MD&A contained in this report. Our strategy calls for continued emphasis on the agricultural sector, while remaining committed to further developing industrial customers who assume the volatility risk associated with the raw material costs and mitigate the effects of seasonality in the agricultural sector.

Our strategy also includes evaluating investment in expansion 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 to construct a new nitric acid plant and concentrator at the El Dorado Facility. During 2015, we completed the construction of the new nitric acid plant and concentrator. We believe that upon completion of the ammonia plant in 2016, the El Dorado Facility will benefit from reduced feedstock costs, expanded capacity, improved efficiency and enhanced product mix flexibility.

Seasonality - Chemical Business

We believe chemical products sold by our Chemical Business to the agricultural industry are seasonal while sales into the industrial and mining sectors generally are not. The selling seasons for agricultural 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 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 operates in a highly competitive market with many other larger chemical companies, such as Agrium, CF Industries, Chemtrade Logistics, CVR Partners, Rentech Nitrogen Partners, OCI Partners, Solvay, Dyno Nobel, Gavilon Fertilizer, Helm, Koch, Norfalco, Potash Corporation of Saskatchewan, Praxair, Quad Chemical, Trammo 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 water source and geothermal heat pumps, hydronic fan coils, large custom air handlers and air and water cooled chillers. 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 West Point Military Academy, Buffet Cancer Center, BMW, NYU Medical Center, Pfizer, Rockefeller Plaza, and Trump Tower. 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.

We believe our Climate Control Business has developed leadership positions in certain product categories by offering extensive product lines and customized products focusing on higher efficiency and “green” technologies. We believe we have developed the most extensive line of water source and geothermal heat pumps and hydronic fan coils in the U.S. and that we are a pioneer in the use of geothermal technology, one of the most energy efficient climate control systems commercially available today. Employing highly flexible production capabilities, we produce both semi-custom and custom design units for new construction as well as the retrofit and replacement markets. This flexibility positions us for growth in commercial/institutional and residential construction markets as those markets continue to recover over the next several years.

Our geothermal heating and air conditioning products 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 continue to maintain a market share leadership position in this sector of the market.

Market Conditions - Climate Control Business

As discussed in more detail in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” contained in this report, information available from the Dodge Construction Market Forecast Service (“CMFS”) indicates that construction activity in the commercial/institutional markets we serve (including multi-family residential structures) is expected to increase 8%, 7% and 5% in the aggregate from 2016 - 2018 and has surpassed pre-recession levels collectively. In particular, the education, office and healthcare vertical end markets of the commercial/institutional sector are expected to grow faster than other vertical end markets we serve. Additionally, single-family residential construction is expected to grow 20% during 2016 to 805,000 units but still remains well below the 1.5 million unit pre-recession levels. In addition to that, we believe low energy prices are adversely affecting new geothermal installations due to the higher installation costs for geothermal as compared to other systems.

Additionally, tax credits and incentives contained in the American Reinvestment Recovery Act of 2009, may have improved sales of our geothermal heat pump products, as well as other “green” products. These tax credits and incentives are scheduled to expire at the end of 2016, which could have an impact on both residential and commercial geothermal heat pump sales if they are not extended.

Water Source and Geothermal Heat Pumps

We believe our Climate Control Business is the leading provider of water source and geothermal heat pumps to the commercial/institutional markets, as well as to single and multi-family residential markets for new construction, renovation and replacement 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 our sales of commercial/institutional water source heat pumps should continue to grow as we continue to invest in new products. These developments will provide our distribution channel, engineers and building owners with product and system features that deliver higher efficiency and long-term value compared to other types of heating and air conditioning systems, whether for new construction, renovation or replacement purposes. The largest markets we serve are the single-family residential sector plus the multi-family, education and office markets in the commercial/institutional sector. Out of these markets, we believe all but the single-family residential market are forecast to show solid opportunity for growth going forward.

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.

Hydronic Fan Coils

We believe that our Climate Control Business is a leading provider of hydronic fan coils targeting commercial and institutional markets including hospitality, multi-family and education sectors. 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 and, have longer lives and lower maintenance costs than other comparable systems used where individual room control is required. Hydronic fan coils are effective 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 customer, to fit the space and capacity requirements of hotels, schools, hospitals, apartment buildings, condominiums, office buildings other commercial/institutional structures, and single family residences. Our backlog consists of confirmed customer orders for product to be shipped at a future date.

Most customers place their product orders well in advance of required delivery dates. The backlog of confirmed customer product orders are discussed under “Key Operational Factors – Climate Control Business” of the MD&A contained in this report.

Distribution - Climate Control Business

Our Climate Control Business sells its products primarily to mechanical contractors, independent manufacturers’ representatives, independent wholesale distributors and original equipment manufacturers (“OEM”s). Our commercial sales to mechanical contractors primarily occur through independent manufacturers' representatives, who also represent complementary product lines not manufactured by us. Our single-family residential sales are primarily made through distributors. 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.

Selling Markets - 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. In the commercial/institutional markets, the largest vertical markets that we focus on, include multi-family residential, education, office, hospitality, healthcare, and retail.

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, electrical components, electric motors, copper, steel, and valves. We do not anticipate any difficulties in obtaining the 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 adversely affect production and costs of our Climate Control products.

Competition - Climate Control Business

Our Climate Control Business operates in a highly competitive market with many other larger HVAC manufacturing companies, such as Carrier Corporation (United Technologies Corporation), Nortek Inc., Trane (Ingersoll-Rand Public Limited Company), WaterFurnace (NIBE Industrier), Bosch Group, Haakon Industries Ltd., McQuay (Daikin Industries, Ltd.) and Energy Labs Inc., 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

Our strategy in our Climate Control Business is to continue to launch new products and product upgrades in an effort to maintain and increase our current market positions and to expand our addressable markets. Further, our plan to drive growth in our Climate Control Business includes:

| · | focusing on obtaining deeper penetration in identifiable vertical markets while expanding our addressable markets for our products;

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

| · | continuing to focus on our Operational Excellence transformation which will result in improvements in safety, quality, on-time delivery, as well as operational efficiencies over time detailed in “Key Operational Factors—Climate Control Business —Operational Excellence Activities in our MD&A” contain in this report.

Additional Segment Information and Foreign and Domestic Operations and Export Sales

Schedules of the amounts of net sales, gross profit, operating income (loss) 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 to Consolidated Financial Statements included in this report.

Employees

As of December 31, 2015, we employed 1,928 persons. As of that date, our Chemical Business employed 576 persons, 197 of whom are represented by unions under agreements that expire in November of 2016 through October of 2018, and our Climate Control Business employed 1,259 persons, none of whom was represented by a union.

Environmental, Health and Safety Matters

Our facilities and operations are subject to numerous federal, state and local environmental laws and to other laws regarding health and safety matters (the “Environmental Laws and 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 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, subsidiaries within our Chemical Business have incurred significant expenditures in order to comply with the Environmental Laws and Health Laws and are reasonably expected to do so 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 still being responsible for its proportionate share of the costs involved.

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, currency exchange rates, 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 operating results, 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

10

to these factors. A decline in the economic activity in the U.S. has in the past had, 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.

Weather conditions adversely affect our Chemical Business and Climate Control 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. Some scientists have concluded that increasing concentrations of greenhouse gases in the Earth’s atmosphere may produce climate changes that have significant physical effects, such as increased frequency and severity of storms, droughts and floods and other climatic events. These climate changes might also occur as the result of other phenomena that human activity is unable to influence, including changes in solar activity and volcanic activity. Regardless of the cause, 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.

In addition, weather conditions, severe or otherwise, may adversely affect the construction, refurbishment and renovation of facilities that utilize our Climate Control products resulting in lower product order levels during those periods.

Our estimates about the funds needed to complete the El Dorado Expansion may not be accurate, which could adversely affect our business and financial condition.

The anticipated cost to complete the expansion of our El Dorado, Arkansas, chemical plant has increased significantly since the beginning of 2015, from our expectation of $485 million to $520 million total cost to our current estimate of $831 million to $855 million (including capitalized interest). Although we believe we have raised sufficient funding to complete the El Dorado Expansion, our current estimates of the amount of funding we need to complete the El Dorado Expansion may prove to be incorrect in the future because the costs may ultimately be higher than our current estimate or our operations may not provide the amount of cash flow we currently project, whether because of chemical plant interruptions, lower selling prices of our products or other events. Accordingly, we may learn in the future that more capital is needed and that we will have to undertake further financing activities or other actions. The past shortfall in cost estimates has had, and any possible future shortfall in cost estimates could have, a material adverse effect on 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 2015, certain of our chemical facilities had planned and unplanned downtime as a result of certain maintenance and equipment issues, including our Pryor Facility that had a total of 70 days of downtime during the third quarter of 2015. As a result, we have experienced 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 use 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 affect our operating results, liquidity and financial condition.

We may not be able to generate sufficient cash to service our debt and may be required to take other actions to satisfy the obligations under our debt agreements or to redeem our preferred stock, which may not be successful.

Our ability to make scheduled payments on our debt obligations and our redemption obligations for the Series E cumulative redeemable Class C preferred stock (“Series E Redeemable Preferred”) depends on our financial condition and operating performance, which is subject to the risks previously described for our El Dorado Expansion, prevailing economic and competitive conditions, and certain financial, business and other factors, some of which may be beyond our control. We may not be able to maintain a level of cash flows sufficient to pay the principal and interest on our debt, including the $425 million principal amount of our 7.75% Senior Secured Notes and the $50 million principal amount of the 12% Senior Secured Notes (collectively, the “Senior Secured Notes”), or if and when applicable, the outstanding amount of the Working Capital Revolver Loan or to pay the cumulative dividends and redemption payment on the Series E Redeemable Preferred should the holder choose to redeem it.

11

If cash flows and capital resources are insufficient to fund our debt, dividend or preferred stock redemption obligations, we could face substantial liquidity problems and will need to seek additional capital through the issuance of debt, the issuance of equity, asset sales or combination of the foregoing. If we are unsuccessful, we will need to reduce or delay investments and capital expenditures, or to dispose of other assets or operations, seek additional capital, or restructure or refinance debt or redeemable equity. These alternative measures may not be successful, may not be completed on economically attractive terms, or may not be adequate for us to meet our debt or preferred stock redemption obligations when due. Additionally, our debt agreements and the operating agreements associated with of our Series E Redeemable Preferred limit the use of the proceeds from many dispositions of assets or operations. As a result, we may not be permitted to use the proceeds from these dispositions to satisfy our debt or preferred stock redemption obligations.

Further, if we suffer or appear to suffer from a lack of available liquidity, the evaluation of our creditworthiness by counterparties and rating agencies and the willingness of third parties to do business with us could be materially and adversely affected. In particular, our credit ratings could be lowered, suspended or withdrawn entirely at any time by the rating agencies, if in each rating agency’s judgment, circumstances warrant. Downgrades in our long-term debt ratings generally cause borrowing costs to increase and the potential pool of investors and funding sources to decrease and could trigger liquidity demands pursuant to the terms of contracts, leases or other agreements. Any future transactions by us, including the issuance of additional debt, the sale of any operating assets, or any other transaction to manage our liquidity, could result in temporary or permanent downgrades of our credit ratings.

Current and future legislative or regulatory requirements affecting our Chemical Business may result in increased costs and decreased revenues, cash flows and liquidity or could have other negative effects 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 that 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 in the past has been, and in the future may 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 results of operation and financial condition. These operating permits are subject to modification, renewal and revocation. In addition, third parties may contest our ability to receive or renew certain permits that we need to operate, which can lengthen the application process or even prevent us from obtaining necessary permits. We regularly monitor and review our operations, procedures and policies for compliance with permits, laws and regulations. Despite these compliance efforts, risk of noncompliance or permit interpretation is inherent in the operation of our businesses.

The trend in environmental regulation is to place more restrictions and limitations on activities that may affect the environment over time. As a result, there can be no assurance as to the amount or timing of future expenditures for environmental compliance or remediation, and actual future expenditures may be different from the amounts we currently anticipate. We try to anticipate future regulatory requirements that might be imposed and plan accordingly to remain in compliance with changing environmental laws and regulations and to minimize the costs of compliance.

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

Explosions and/or losses at other chemical facilities that we do not own (such as the explosion in West, Texas) could also result in new or additional legislation or regulatory changes, particularly relating to public health, safety or any of the products manufactured and/or sold by our Chemical Business or the inability on the part of our Chemical Business’ customers to obtain or maintain insurance as to certain products manufactured and/or sold by our Chemical Business, which could have a negative effect on the revenues, cash flow and liquidity of our Chemical Business.

In summary, new or changed laws and regulations or the inability of the customers of our Chemical Business to obtain or maintain insurance in connection with any of our chemical products 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 to 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 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 transportation of our products. These costs could have a material effect on our results of operations, financial condition, and liquidity. The cost of such regulatory changes, if

12

significant enough, could lead some of our customers to choose other products to ammonia and AN, which would have a significant adverse effect 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”) published a notice of the 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 comply with certain other new requirements. We and others affected by this proposal have submitted appropriate comments to DHS regarding the proposed regulation. It is possible that DHS could significantly revise the requirements currently being proposed. 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. The proposed rule did not promulgate in 2015 and DHS may be considering significant changes compared to the original proposed rule. Although we cannot predict the timing or content of any DHS regulation, we believe implementation of a final rule appears unlikely in 2016.

On August 1, 2013, U.S. President Obama issued an executive order 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 President directed federal agencies to enhance existing regulations and make recommendations to the U.S. Congress to develop new laws that may affect our Chemical Business. For example, the EPA is expected to propose a revision to its Risk Management Program in March 2016. OSHA is likewise considering changes to its Process Safety Management standards. In addition, DHS, the EPA, and the Bureau of Alcohol, Tobacco, Firearms and Explosives updated a joint chemical advisory on the safe storage, handling, and management of AN. In January 2016 the U.S. Chemical Safety and Hazard Investigation Board (“CSB”) released its final report on the West, Texas incident. The CSB report identifies several federal and state regulations and standards that could be strengthened to reduce the risk of a similar incident occurring in the future. While the CSB does not have authority to directly regulate our business, the findings in this report, and other activities taken in response to the West, Texas incident by federal, state, and local regulators may result in additional regulation of processes and products in our Chemical Business.

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

The manufacturing facilities in 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 legislatures and administrative agencies, including the EPA, are considering the scope and scale of greenhouse gas or other air emission regulation. Legislation and administrative actions are being considered that would regulate greenhouse gas emissions at some point in the future for our facilities, and existing and possible actions have already affected 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 affects 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 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. For instance, the EPA recently published a rule, known as the Clean Power Plan, to limit greenhouse gases from electric power plants. Judicial challenges have been filed, which seek a stay of the implementation of the rules. On February 9, 2016, the Supreme Court stayed the implementation of the Clean Power Plan while legal challenges to the rule proceed. Depending on the outcome of those challenges, and how various states choose to implement this rule, the Clean Power Plan could result in greater electric costs, more use of alternative energy sources, and a decreased demand for coal-generated electricity.

The Clean Power Plan is one of many recent developments aimed at limiting greenhouse gas emissions that could adversely affect our clients in the coal industry, and thus limit the market for some of our products. Enactment of laws or passage of regulations regarding emissions from the combustion of coal by the United States, states, or other countries could also result in electricity generators further switching from coal to other fuel sources or result in additional coal-fueled power plant closures. For example, the 2015 Paris climate summit agreement resulted in voluntary commitments by numerous countries to reduce their GHG emissions, and could result in additional firm commitments by various nations with respect to future GHG emissions. These commitments could further disfavor coal-fired generation, particularly in the medium- to long-term. In addition, the U.S. Department of the Interior recently announced a moratorium on issuing certain new coal leases on federal land while the Bureau of Land Management undertakes a programmatic review of the federal coal program. Pressure from advocacy groups and policies limiting available financing for the development of new coal-fueled power plants could also adversely affect the demand for coal in the future, and thus limit the market for some of our products.

13

As it relates to our Chemical Business’ working interest in natural gas properties, legislative and regulatory proposals for restricting greenhouse gas or other air 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. For instance, the EPA has proposed New Source Performance Standards for methane and volatile organic compound emissions from certain activities in the oil and gas sector, as well as a new definition of oil and gas sources, and new draft Control Techniques Guidelines for reducing volatile organic compound emissions from existing oil and gas sources in certain ozone nonattainment areas. If the rules are adopted as proposed, these rules could impose new compliance costs and permitting burdens on natural gas production.

In addition, the EPA has recently lowered the national ambient air quality standard for ground level ozone, which could result in additional compliance requirements for natural gas operations in areas of the country that have failed to attain the new, lower standard. The EPA has not yet designated which areas of the country are out of attainment, and it will take the states several years to develop compliance plans for their non-attainment areas. It is difficult to predict how these and any other possible regulations, if and when adopted, will affect our businesses, operations, liquidity or financial results.

There is intense competition in the Chemical and Climate Control 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 many companies, domestic and foreign, that have greater financial, marketing and other resources. Specifically, the overall nitrogen market is expected to be affected as a result of the number of announced and started nitrogen expansion projects in the U.S. Competitive factors could require us to reduce prices or increase spending on product development, marketing and sales, which could have a material adverse effect on our business, results of operation and financial condition.

Our Chemical Business competes with many U.S. producers and producers in other countries, including state-owned and government-subsidized entities. Some competitors have greater total resources and are less dependent on earnings from chemical sales, which make them less vulnerable to industry downturns and better positioned to pursue new expansion and development opportunities. Our competitive position could suffer to the extent we are not able to expand our own resources sufficiently either through investments in new or existing operations or through acquisitions, joint ventures or partnerships. An inability to compete successfully could result in the loss of customers, which could adversely affect our sales and profitability.

We may pursue various transactions and initiatives to address our highly leveraged balance sheet and significant cash flow requirements.

If our existing financing sources are insufficient for our financing needs, or if we are unable to refinance debt and redemption obligations as they become due, we may be required to reduce or delay investments and capital expenditures (including the El Dorado Expansion), dispose of assets or operations, seek additional capital, restructure or refinance debt, or undertake a combination of some or all of these. Any transactions and initiatives that we may pursue may have significant adverse effects on our business, capital structure, ownership, liquidity, credit ratings and results of operations. These measures may not be successful, may not produce the desired outcome if completed, may not be completed on economically attractive terms, and may not be adequate for us to fund the El Dorado Expansion and to meet our debt or redemption obligations when due. This could ultimately adversely affect us, our debtholders, and our shareholders in a material manner.

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

For 2015, seven customers of our Chemical Business accounted for approximately 52% of its net sales and 31% of our 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.

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. In addition, certain of our raw materials and components are subject to tariff

14

controls and other international trade barriers, which may increase the uncertainty of raw material and component availability and pricing volatility.

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. Also the spot sales prices of our agricultural products may not correlate to the ammonia and natural gas feedstock costs but rather reflect market conditions for similar and competing nitrogen sources. This lack of correlation can compromise our ability to recover our full cost to produce the products in this market. 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. Future price fluctuations in our raw materials may 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.

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 affect 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 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, imports of fertilizer grade AN from certain Russian producers 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%. Since 2014, the duty rates for two Russian producers and exporters were reduced to zero following a U.S. Commerce Department (“DOC”) annual review of pricing by these entities. The antidumping orders that exist on the Ukrainian and Russian product have substantially restrained the volumes of these imports in the past, but the 2014 temporary duty elimination for certain exporters resulted in increased Russian imports in 2015. If DOC continues to assign zero duty rates to certain Russian exporters at the end of the current annual review, the volumes of Russian fertilizer grade AN exported to the U.S. may continue to increase, possibly priced below our current cost to produce fertilizer grade AN. Moreover, two federal government agencies will begin a “sunset review” in 2016 to determine whether to continue the Russian antidumping duty order for another five years or terminate it. 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 had 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 that 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, the coverage 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.

Furthermore, we are subject to litigation for which we could be obligated to bear legal, settlement and other costs, which may be in excess of any available insurance coverage. While we maintain insurance, there can be no assurance that our insurance will prove to be adequate. If we are required to incur all or a portion of the costs arising out of any litigation or investigation as a result of inadequate insurance proceeds, if any, our business, results of operations, financial condition and liquidity could be materially

15

adversely affected. For further discussion of our litigation, please see “Other Pending, Threatened or Settled Litigation” in Note 11 to Consolidated Financial Statements included in this report.

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, including dividend requirements relating to our preferred stock, 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 and dividend requirements relating to our preferred stock. As a result, this level could, among other things:

| · | require us to dedicate a substantial portion of our cash flow to the payment of principal (primarily relating to 2019), interest and dividends, 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 affect our ability to obtain financing in the future and increase the cost of such financing.

Any of the foregoing could adversely affect 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. Although we have employment agreements with certain of our principal executive officers, including Jack E. Golsen, Daniel D. Greenwell, and Mark T. Behrman, we do not have employment agreements with all of our key personnel. 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 crises, etc.), have negatively affect and could negatively affect U.S. and foreign companies, the financial markets, the industries where we operate, our operations and our profitability.

Terrorist attacks in the U.S and elsewhere and natural disasters (such as hurricanes or pandemic health crises) have in the past negatively affected, 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 materials, our business, results of operations and financial condition. In addition, terrorist attacks and natural disasters may directly affect our physical facilities, especially our chemical facilities, or those of our suppliers or customers and could affect 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 affected our operations and those of our customers. As previously noted, some scientists have concluded that increasing concentrations of greenhouse gases in the Earth’s atmosphere may produce climate changes that have significant physical effects, such as increased frequency and severity of storms, droughts and floods and other climatic events. If any such effects, whether anthropogenic or otherwise, were to occur in areas where we or our clients operate, they could have in adverse effect on our assets and operations. 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.

Risks associated with capital projects may prevent the completion of those projects on budget, on schedule or at all.

We are undertaking capital projects and may undertake additional capital projects in the future. Capital projects entail risks, including, but not limited to:

| · | unanticipated cost increases;

| · | unforeseen engineering or environmental problems;

| · | work stoppages;

| · | weather interference;

| · | unavailability of necessary equipment; and

| · | unavailability of financing on acceptable terms.

Construction, equipment or staffing problems or difficulties in obtaining any of the requisite licenses, easements, permits and authorizations from regulatory authorities could increase the total cost and could delay or prevent the construction or completion of a capital project.

In addition, a capital project could be negatively affected if we are required to obtain additional debt or equity financing to complete a capital project or we are unable to obtain adequate sources of funding, such as the inability to obtain other debt or equity financing on acceptable terms or at all. Moreover, if we are able to complete a capital project, production levels at our facilities or general market conditions may not meet our expectations. As a result of these factors, our results of operations, liquidity and financial condition could be adversely affected.

Risks generally associated with implementation of an enterprise resource planning (“ERP”) system may adversely affect our business operation and the effectiveness of internal control over financial reporting.

We have begun to implement an ERP system, which, when completed, will handle the business and financial processes of our subsidiaries’ operations and our corporate and administrative functions, such as:

| · | facilitating the process of purchasing, manufacturing and distributing inventories;

| · | receiving, processing, and shipping orders on a timely basis,

| · | managing the accuracy of billings and collections for our customers;

| · | processing payments to our suppliers;

| · | managing the accuracy of payroll; and

| · | generating financial transactions, information and reports.

ERP implementations are complex and time-consuming projects that involve substantial expenditures on system software and implementation activities that can continue for several years. ERP implementations also require transformation of business and financial processes in order to benefit from a new ERP system. Our results of operations, liquidity and financial condition may be adversely affected if we experience operating problems and cost overruns during the ERP implementation process or if the ERP system (and the associated process changes) does not generate the expected benefits. Additionally, if we do not effectively implement the ERP system as planned or if the system does not operate as intended, it could adversely affect our financial reporting.

Cyber security risks could adversely affect our business operations.

As we continue to increase our dependence on information technologies to conduct our operations, the risks associated with cyber security also increase. We rely on our ERP and other information systems, among other things, to manage our manufacturing, supply chain, accounting and financial functions. This risk not only applies to us, but also to third parties on whose systems we place significant reliance for the conduct of our business. We have implemented security procedures and measures in order to protect our information from being vulnerable to theft, loss, damage or interruption from a number of potential sources or events. Although we believe these measures and procedures are appropriate, we may not have the resources or technical sophistication to anticipate, prevent, or recover from rapidly evolving types of cyber-attacks. Compromises to our information systems could have an adverse effect on our results of operations, liquidity and financial condition.

17

Certain of our stockholders control a significant amount of our voting stock, and their interests could conflict with interests of other stockholders.

LSB Funding LLC (“LSB Funding”), our largest voting shareholder, an unrelated third party, owns one share of Series F redeemable Class C preferred stock (the “Series F Redeemable Preferred”), which has voting rights with common stock equal to 19.4% of the outstanding shares of LSB’s common stock as of February 19, 2016.

Jack E. Golsen, our Executive Chairman of our the Board of Directors (the “Board”), members of his immediate family, including Barry H. Golsen, a member of our Board, entities owned by them, and trusts for which they possess voting or dispositive power as trustee (the “Golsen Holders”) owned as of February 19, 2016, an aggregate of 2,815,064 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 vote as a class and represent approximately 15% 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.

Pursuant to a Board Representation and Standstill Agreement entered into in connection with LSB Funding’s purchase of preferred stock in December 2015, LSB Funding has the right to designate three directors on our Board, and the Golsen Holders have the right to appoint two directors, subject to reduction in each case in certain circumstances. This is in addition to their ability to vote generally in the election of directors. As a result, each of LSB Funding and the Golsen Holders have significant influence over the election of directors to our Board.

The interests of LSB Funding and the Golsen Holders may conflict with interests of other stockholders (as well as with each other). As a result of the voting power and board designation rights of LSB Funding and the Golsen Holders, the ability of other stockholders to influence our management and policies could be limited.

Our debt agreements and our preferred stock contain covenants and restrictions that limit flexibility in operating our businesses. A breach of these covenants or restrictions could result in an event of default under one or more of our debt agreements or contracts at different entities within our capital structure, including as a result of cross acceleration or default provisions.

Our debt agreements and our preferred stock contain various covenants and other restrictions that, among other things, limit flexibility in operating our businesses. A breach of any of these covenants or restrictions could result in a significant portion of our debt becoming due and payable or could result in significant contractual liability. Our ability to comply with certain of our covenants and restrictions can be affected by events beyond our control. These covenants and other restrictions limit our ability to, among other things:

| · | incur additional debt or issue preferred shares;

| · | pay dividends on, repurchase or make distributions in respect of capital stock or make other restricted payments;

| · | make investments;

| · | sell or transfer assets;

| · | create liens on assets to secure debt;

| · | consolidate, merge, sell or otherwise dispose of all or substantially all of our assets;

| · | enter into transactions with affiliates;

| · | designate subsidiaries as unrestricted subsidiaries, and

| · | repay, repurchase or modify certain subordinated and other material debt.

There are a number of important limitations and exceptions to these covenants and other restrictions.

In addition, certain failures to make payments on significant contract obligations when due constitute a cross-default of some of our debt instruments, including the note purchase agreement governing our 12% Senior Secured Notes (the “Senior Secured Note Purchase Agreement”) and the indenture governing our 7.75% Senior Secured Notes (the “Senior Secured Notes Indenture”). A breach of any of these covenants or restrictions could result in an event of default under one or more of our debt agreements at different entities within our capital structure, including as a result of cross acceleration or default provisions. Upon the occurrence of an event of default under one of these debt agreements, our lenders or noteholders could elect to declare all amounts outstanding under that debt agreement to be immediately due and payable and/or terminate all commitments to extend further credit. Such actions by those lenders or noteholders could cause cross defaults or accelerations under our other debt. If we were unable to repay those amounts, the lenders or noteholders could proceed against any collateral granted to them to secure such debt. In the case of a default

18

under debt that is guaranteed, holders of such debt could also seek to enforce the guarantees. If lenders or noteholders accelerate the repayment of all borrowings, we would likely not have sufficient assets and funds to repay those borrowings. Such occurrence could result in our or our applicable subsidiary going into bankruptcy, liquidation or insolvency.

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

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. Although our Board has not made a decision whether or not to pay dividends on our common stock in 2016, it is unlikely we will pay dividends on our common stock until we have repaid or refinanced our debt and our preferred stock. In addition, there are certain limitations contained in our loan and securities purchase agreements that may limit our ability to pay dividends on our outstanding common stock.

Future issuances or potential issuances of our common stock or preferred equity could adversely affect the price of our common stock and our ability to raise funds in new stock offerings and could dilute the percentage ownership or voting power of our common stockholders.

Future sales of substantial amounts of our common stock, preferred stock or equity-related securities in the public market, or the issuance of a substantial amount of our common stock as the result of the exercise of our outstanding warrants, the 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 common stock, preferred stock, or equity-related securities, exercises of our warrants 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, exercises, or conversions could also significantly reduce the percentage ownership and voting power of our existing 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 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, the officer would be entitled to certain severance benefits. Certain of our preferred stock series and debt instruments also provide special rights in a change of control, including in some cases the ability to be repaid in full or redeemed.

We have authorized and unissued (including shares held in treasury) 51,603,779 shares of common stock and 4,019,999 shares of preferred stock as of December 31, 2015. 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. In addition, LSB Funding and the Golsen Holders have significant voting power and rights to designate board representatives, all of which may further discourage a third party tender offer, proxy contest, or other attempts to acquire control of us.

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 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; or

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

The following Management’s Discussion and Analysis of Financial Condition and Results of Operations should be read in conjunction with a review of the other Items included in this Form 10-K and our December 31, 2015 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 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 for the agricultural, industrial, and mining markets it produces from four facilities located in El Dorado, Arkansas; Cherokee, Alabama; Pryor, Oklahoma; and Baytown, Texas.

| · | Climate Control Business manufactures and sells a broad range of HVAC products that include water source and geothermal heat pumps, hydronic fan coils, large custom air handlers, modular geothermal and other chillers, and other related products and services. These products are primarily used in commercial/institutional and residential new buildings 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.

Key Expectations for 2016

The new ammonia plant at the El Dorado Facility was mechanically complete in February 2016 and should begin production early in the second quarter of 2016. We define mechanical completion as it relates to the El Dorado ammonia plant as having concluded the installation of process vessels and rotating equipment, including associated piping and valves. Additionally, utility equipment systems such as cooling water, steam generation, raw water treatment, and air systems, along with related piping, have been installed. Currently, all that remains to fully complete construction activities at the El Dorado ammonia plant is the connection of the electronic instrumentation wiring to the field instruments, along with the painting and insulation of the piping and process vessels, and the final grading and concrete containment for proper drainage of the process areas.

Management and our Board, as previously announced, will continue to review strategic alternatives for our businesses in order to maximize shareholder value including asset sales and/or the separation of our two businesses. Additionally, once the El Dorado ammonia plant becomes operational, we intend to explore refinancing our capital structure.

Key Capital Expenditure, Financing and Other Developments – 2015

The El Dorado Facility has certain expansion projects underway, a portion of which have been completed. These expansion projects include an ammonia production plant; a new 65% strength nitric acid plant and nitric acid concentrator; and other support infrastructure. The new nitric acid concentrator went into production in June 2015, and the new nitric acid plant went into production during November 2015. The new ammonia plant was mechanically complete in February 2016 and should begin production early in the second quarter of 2016.

During 2015, management in conjunction with the owner’s representative, the engineering, procurement and construction contractor and other consultants determined that the total cost to complete the El Dorado Expansion would exceed what we previously projected at the beginning of the year, due, in part, to an under-estimation of the budgeted costs, work performed by a former subcontractor and mechanical and piping labor cost increases compared to earlier estimates. We have now determined that the total cost to complete the El Dorado Expansion is estimated to be in the range of $831 million to $855 million, of which $705 million was spent as of December 31, 2015 and $126 million to $150 million is estimated to be spent in 2016.

Although we had begun seeking additional debt financing to address what were then our known costs of the El Dorado Expansion during the third quarter of 2015, the reluctance of existing bondholders to permit additional senior indebtedness unless we obtained additional equity caused us to reevaluate our financing plans and liquidity needs while we also worked to define the new cost estimates. As a result of that analysis, we concluded that our liquidity needs to complete the projects would exceed available debt financing, particularly in light of our existing debt covenants limiting the incurrence of additional indebtedness. Given that publicly offered financing would be unavailable before we had defined the cost estimates and the release of our 2015 third quarter results and would probably be unavailable even after those events, our options were either to obtain other financing solutions in order for us to

27

continue the projects or delay or stop the projects during the fourth quarter of 2015 to preserve our liquidity for other operations, which, without the El Dorado costs, are generally self-sustaining. We also took additional steps to address our liquidity concerns, including obtaining extended payment terms, for a limited time during the fourth quarter, from Leidos our EDC contractor, f or our El Dorado Expansion and by obtaining financing for discrete pieces of equipment.

We considered and explored financing options including debt, equity-linked and equity as well as potential asset sales. As part of those considerations we took into account our permitted indebtedness limits, the costs and likelihood of obtaining consents to raise our permitted indebtedness limits, the sale of one or more of our significant assets or divisions, and various forms of equity issuances. We recognized that, without additional financing, some counterparties to contracts might begin changing payment terms and requiring cash payments in advance, which would further impair our liquidity and affect our business. We evaluated our choices based on timing of financing, certainty of completion, and short- and long-term costs. Ultimately, based on the choices available after analyzing and pursuing various options, we concluded that termination or delay of the El Dorado Expansion would significantly impair the long-term value of the Company compared to the costs and benefits of a private debt and equity financing solution and that a sale of significant assets was not likely to be completed in the timeframe needed at an appropriate price. Therefore during the fourth quarter of 2015, we entered into the following agreements as summarized below:

12% Senior Secured Notes

On November 9, 2015, LSB sold $50 million aggregate principal amount of the 12% senior secured notes due 2019 (the “12% Senior Secured Notes”) in a private placement exempt from registration under the Securities Act. The 12% Senior Secured Notes bear interest at the annual rate of 12% and mature on August 1, 2019. Interest is to be paid semiannually on February 1st and August 1st, which began February 1, 2016. The 12% Senior Secured Notes are secured on a pari passu basis with the same collateral securing LSB’s existing $425 million aggregate principal amount of 7.75% Senior Secured Notes issued in 2013 (the “7.75% Senior Secured Notes”). The 12% Senior Secured Notes have covenants and events of default that are substantially similar to those applicable to the 7.75% Senior Secured Notes. See further discussion in Note 9 to Consolidated Financial Statements contained in this report.

Securities Purchase Agreement

On December 4, 2015, LSB entered into a securities purchase agreement (the “Securities Purchase Agreement”) with an unrelated third party, LSB Funding, (“LSB Funding”) pursuant to which LSB sold to LSB Funding, in a private placement exempt from registration under the Securities Act the following:

| · | $210 million of Series E Redeemable Preferred which includes participation rights in dividends and liquidating distributions,

| · | a warrant to purchase 4,103,746 shares of our common stock, par value $0.10, which number of shares is equal to 17.99% of the outstanding shares of our common stock before the completion of this private placement (the “Warrants”), and

| · | one share of Series F Redeemable Preferred which has voting rights with common stock equal to 19.99% of the outstanding shares of our common stock before the completion of this private placement.

See further discussion in Note 13 to Consolidated Financial Statements contained in this report.

Registration Right Agreements

In connection with the 12% Senior Secured Notes, LSB entered into a registration rights agreement (the “Registration Rights Agreement-Notes”). Pursuant to the Registration Rights Agreement-Notes, we have agreed to use our reasonable best efforts to file with the SEC a registration statement on an appropriate form with respect to a registered offer to exchange the 12% Senior Secured Notes for new notes with terms substantially identical in all material respects to the 12% Senior Secured 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.

In connection with the Securities Purchase Agreement, LSB entered into a registration rights agreement (the “Registration Rights Agreement-Warrants”) relating to the registered resale of the common stock issuable upon exercise of the Warrants and certain other common stock. Pursuant to the Registration Rights Agreement-Warrants, we are required to file a registration statement for such registered resale within nine months from December 4, 2015 (the “Closing Date”), to permit the public resale of registrable securities then outstanding from time to time as permitted by Rule 415 under the Securities Act. We are required to use commercially reasonable efforts to cause the registration statement to become effective as soon as practicable thereafter. Furthermore, the registration statement must be declared effective within twelve months after the Closing Date by filing a post-effective amendment.

28

Board Representation and Standstill Agreement

On the Closing Date, LSB and the Purchaser entered into a Board Representation and Standstill Agreement. Pursuant to the Board Representation and Standstill Agreement, we agreed to permit LSB Funding to appoint three nominees to our Board of Directors (the “Board”). Until the Board Designation Termination Date (as defined in the agreement), so long as LSB Funding or its affiliates own the Series E Redeemable Preferred or the Warrants, LSB Funding will continue to be entitled to designate three directors. In the event of redemption in full of the Series E Redeemable Preferred by LSB, LSB Funding will be entitled to designate only two directors so long as LSB Funding owns the Warrants or any shares of our common stock issuable thereunder. However, LSB Funding will be entitled to designate only one director nominee in the event LSB Funding and its affiliates collectively cease to beneficially own at least 10% (but not greater than 24.99%) of our common stock issued pursuant to the Warrants (whether owned directly or as a right to acquire upon exercise of the Warrants). LSB Funding’s rights to designate any directors will terminate when LSB Funding and its affiliates collectively cease to beneficially own at least 10% of our common stock issued pursuant to the Warrants (whether owned directly or as a right to acquire upon exercise of the Warrants).

Under the Board Representation and Standstill Agreement, the Golsen Holders, collectively, have the right to designate two directors; however, if the Golsen Holders, collectively, continue to beneficially own at least 2.5% (but not 5% or more) of the then outstanding Common Stock, the Golsen Holders will be entitled to designate up to one director. These designation rights will terminate immediately on the first date on which the Golsen Holders, collectively, no longer beneficially own at least 2.5% of the then outstanding common stock.

From and including the Closing Date through and including the annual meeting of stockholders to elect directors to the Board in 2016 (including any adjournments and postponements thereof), LSB Funding and the Golsen Holders have agreed that, at any meeting of the stockholders or in any other circumstances upon which a vote, consent or other approval of all or some of the stockholders is sought solely with respect to the matters described below, they will vote (or cause to be voted) or execute (or cause to be executed) consents with respect to, as applicable, all of our securities owned as of the applicable record date in favor of the election of the persons named in our proxy statement as the Board’s nominees for election as directors, and against any other nominees.

During the period commencing on the Closing Date and ending on the Standstill Termination Date (as defined below), LSB Funding has agreed that it will not, and will cause its affiliates not to, directly or indirectly, among other things:

| · | engage in any hostile or takeover activities with respect to LSB (including by means of a tender offer or soliciting proxies or written consents, other than as recommended by the Board);

| · | acquire or propose to acquire beneficial ownership of additional LSB common stock (other than the common stock issuable upon exercise of the Warrants) or other LSB securities that in the aggregate, together with their beneficial ownership of any other units, is equal to beneficial ownership of 20% or more of the voting power of the outstanding common stock (taking into account the voting rights of our common stock underlying the Warrants and the Series F Redeemable Preferred), provided that, the foregoing will not prohibit or apply to the receipt of any common stock paid as dividends on the Series E Redeemable Preferred held by LSB Funding or any of its affiliates or any common stock issued in exchange for the redemption of the Series E Redeemable Preferred held by LSB Funding or any Purchaser affiliates, and such Series E Redeemable Preferred and common stock shall not be taken into account for purposes of establishing compliance with the foregoing;

| · | acquire or propose to acquire any other LSB securities or any securities of any of our affiliates;

| · | call a special meeting of the stockholders; or

| · | propose to remove, or vote to remove, any directors, other than in accordance with the Board Representation and Standstill Agreement. “Standstill Termination Date” means the earlier of (1) 90 days after the Board Designation Termination Date and (2) the later of (A) the fifth anniversary of the Closing Date and (B) 90 days after the date on which all directors designated by LSB Funding pursuant to the Board Representation and Standstill Agreement have resigned or been removed from the Board, and LSB Funding has permanently waived and renounced its Board designation rights under the Board Representation and Standstill Agreement.

Ammonia Purchase and Sale Agreement

In November 2015, EDC and Koch Fertilizer entered into an ammonia purchase and sale agreement under which Koch Fertilizer agreed to purchase, with minimum purchase requirements, the ammonia that is in excess of El Dorado’s internal needs as discussed in Note 11 to Consolidated Financial Statements.

29

Significant Financial Development s – 2015

Our financial developments during 2015 included the following items:

| · | Our consolidated operating loss for 2015 was $50.8 million, including an operating loss of $41.8 million from our Chemical Business. The following items contributed to the Chemical Business operating loss:

| · | a $43.2 million non-cash impairment charge primarily consisting of a $39.7 million non-cash impairment charge to reduce the carrying value of our working interest in natural gas properties in the Marcellus Shale region primarily as the result of a decline in forward prices for natural gas, large natural gas price differentials in the Marcellus Shale region and changes in the drilling plans of these natural gas properties (see discussion below under “Critical Accounting Policies and Estimates”) and a $3.5 million non-cash impairment charge recorded by our Pryor Facility to reduce the carrying value of certain plant assets related to unused ammonia production equipment;

| · | a $19.1 million negative impact on operating results due to the planned and unplanned downtime experienced at the Pryor Facility. During the third quarter of 2015 ($15.6 million) and unplanned outage and resulting maintenance costs during the fourth quarter of 2015 ($3.5 million to $4.0 million);

| · | a $27 million increase in operating losses at the El Dorado Facility resulting from the impact of the expiration of the Orica Agreement related to the sale of industrial grade AN (“LDAN”) and lower sales volume of agricultural grade AN (“HDAN”) primarily as the result of unfavorable weather conditions that curtailed the fall fertilizer application season, partially offset by;

| · | a $13.0 million improvement in operating results, after adjusting for a $28 million insurance recovery in 2014, at the Cherokee Facility primarily due to overall higher on-stream rates as this facility was not required to perform major planned maintenance (a “Turnaround”) during 2015.

Key Industry Factors

Chemical Business

Supply and Demand

Agricultural

The price at which our agricultural products are ultimately sold depends on numerous factors, including the supply and demand for nitrogen fertilizers which, in turn, depends upon world grain demand and production levels, the cost and availability of transportation, storage, weather conditions, competitive pricing and the availability of imports, among other factors. An expansion or upgrade of competitors’ facilities, international and domestic political and economic developments and other factors are likely to continue to play an important role in nitrogen fertilizer industry economics. These factors can impact, among other things, the level of inventories in the market, resulting in price volatility and product margins.

Corn prices affect the number of acres of corn planted in a given year, and the number of acres planted will drive nitrogen fertilizer consumption, likely driving ammonia, UAN and urea prices. Weather also will have an impact on fertilizer consumption. Although the latest World Agricultural Supply and Demand Estimates Report, report dated January 12, 2016 estimates record world corn ending stocks for 2015/2016 at 208.9 million tons, more than half of these tons are estimated to be held in China. Despite the record ending stocks, the USDA is estimating the U.S. growers will plant 90.5 million acres of corn in 2016 compared to 88.0 million in 2015. At present, the overall fertilizer market continues to be under pressure as inventories of fertilizer products at distributors and producers remain high due to the contracted fall application season and farmers and dealers delaying purchases as they believe fertilizer pricing will continue to drop. However, spring nitrogen movement is expected to be stronger in 2016 compared to 2015 given the increase in estimated planted acres in 2016 and that the 2015 fall nitrogen fertilizer application was disappointing due to poor weather conditions. Along with farmer and dealers delaying purchases, the strong U.S. dollar makes the U.S. an attractive market for importers to bring in product at lower prices, which is putting further pressure on the market. With the spring application season rapidly approaching, we believe that nitrogen fertilizer prices will recover as more fertilizer will need to be applied to maintain the yield achieved over the past two seasons given the truncated fall application season and imports continuing to run below the levels set last year.

Industrial

Our industrial products sales volumes are dependent upon general economic conditions primarily in the housing, automotive, and paper industries. According to the American Chemistry Council, the U.S. economic indicators continue to be mostly positive for these sectors domestically. Our sales prices generally vary with the market price of our feedstock (ammonia or natural gas, as applicable) in our pricing arrangements with customers.

30

Mining

Our mining products are LDAN and AN solutions. The primary uses are as AN fuel oil and specialty emulsions for surface mining of coal and for usage in quarries and the construction industry. As reported by the EIA, annual coal production in the U.S. for 2015 is estimated to be down 11%. EIA also forecasts an additional 6% decrease in U.S. coal production in 2016. The Appalachia region drove the decline in coal production with an estimated decline of approximately 15% from 2015. The Powder River Basin and Illinois Basin are estimated to have declined approximately 9% and 11%, respectively. Although the majority of our LDAN and AN solutions are used in the Powder River Basin which has experienced a slower rate of decline, we believe that coal production in the U.S. will face significant challenges assuming natural gas prices remain at current levels and given that export demand is expected to be lower due to the current strength of U.S. currency. While we believe our plants are well-located to support the regions that are more stable in the upcoming years, our current mining sales volumes are being impacted by overall lower customer demand for LDAN.

Farmer Economics

The demand for fertilizer is affected by the aggregate crop planting decisions and fertilizer application rate decisions of individual farmers. Individual farmers make planting decisions based largely on prospective profitability of a harvest, while the specific varieties and amounts of fertilizer they apply depend on factors, such as farmers’ financial resources, soil conditions, weather patterns and the types of crops planted.

Natural Gas Prices

Natural gas is the primary feedstock for the production of nitrogen fertilizers at our Cherokee and Pryor Facilities and will be upon the completion of the construction of the ammonia plant at our El Dorado Facility. Over the last five years, U.S. natural gas reserves have increased significantly due to, among other factors, advances in extracting shale gas, which has reduced and stabilized natural gas prices, providing North America with a cost advantage over certain imports. As a result, our competitive position and that of other North American nitrogen fertilizer producers have been positively impacted.

We historically have purchased natural gas in the spot market or through the use of forward purchase contracts, or a combination of both and have used forward purchase contracts to lock in pricing for a portion of our natural gas requirements. These forward purchase contracts are generally either fixed-price or index-price, short-term in nature and for a fixed supply quantity. We are able to purchase natural gas at competitive prices due to our connections to large distribution systems and their proximity to interstate pipeline systems. Over the past several years, natural gas prices have experienced significant downward fluctuations, which have had a positive impact on our cost of producing nitrogen fertilizer. The following table shows the annual volume of natural gas we purchased and the average cost per MMBtu:

|  | 2015 |  |  | 2014 |
Natural gas volumes (MMBtu in millions) |  |  | 11 |  |  |  | 11 |
Natural gas average cost per MMBtu |  | $ | 3.19 |  |  | $ | 4.28 |

For 2016 we have forward purchase commitments of natural gas for approximately 3 million MMBtus for our Cherokee Facility, approximately 2 million MMBtus for our Pryor Facility and approximately 2 million MMBtus for our El Dorado Facility at an average cost of $2.76 per MMBtu. This represents approximately 30% of our exposed natural gas usage at each facility for 2016.

Ammonia Prices

Currently, ammonia is the primary feedstock for the production of HDAN and LDAN at our El Dorado Facility. That will continue until the new ammonia plant being constructed is operational which is expected to occur in the second quarter of 2016. Ammonia pricing is based on a published Tampa, Florida market index pursuant to an ammonia purchase agreement with Koch Nitrogen International Sarl (“Koch”), under which Koch agrees to supply certain of the El Dorado Facility’s ammonia requirements. Under an amended agreement, the El Dorado Facility will purchase a majority of its ammonia requirement from Koch through the earlier of December 31, 2016 or the date on which the new ammonia plant comes on stream at the El Dorado Facility. The Tampa index is commonly used in annual contracts for the industrial sectors, and is based on the most recent major industry transactions in the Tampa market. Pricing considerations for ammonia incorporate international supply-demand, ocean freight and production factors. Subject to availability, the El Dorado Facility has the ability to source a portion of its ammonia requirements from our Pryor Facility, which costs are significantly less than current market prices. Once our new ammonia production plant at the El Dorado Facility commences production we believe this cost disadvantage will be eliminated. Over the past several years, ammonia prices have experienced large fluctuations. Additionally, the El Dorado Facility’s cost to produce HDAN from purchased ammonia can at times exceed our selling price (a cost disadvantage as compared to producing ammonia from natural gas) as discussed below.

31

Based upon full plant production, the El Dorado Facility would expect to require 200,000 to 220,000 tons per year of ammonia feedstock to upgrade to other products. During 2015, the purchased ammonia was less than the amount required for full production due to lower production of:

| · | HDAN tons due to adverse weather conditions and cautious buyers resulting from falling nitrogen product selling prices and;

| · | LDAN production caused by low natural gas prices affecting the overall demand for coal translating to lower U.S. coal production combined with EDC currently being a high cost producer causing customers to purchase LDAN from competitors.

The table below shows the El Dorado Facility’s annual volume of ammonia purchased and the average cost per short ton:

|  | 2015 |  |  | 2014 |
Ammonia volumes (tons in thousands) |  |  | 121 |  |  |  | 138 |
Ammonia average cost per short ton |  | $ | 455 |  |  | $ | 506 |

It is expected that this overall trend will continue into the second quarter of 2016 until we begin operating our new ammonia production plant at the El Dorado Facility and will negatively impact our operating results until that point. We have executed contracts with customers with expected purchase requirements of 150,000 tons per year of LDAN a portion of which include minimum purchase requirement volumes. With the recent downturn in the mining industry, we are unsure if we will reach these sales levels. These contracts begin in 2016.

As mentioned above, our El Dorado Facility is currently at a cost disadvantage since it purchases ammonia compared to products produced with ammonia that were produced from natural gas. This cost disadvantage combined with the impact of the expiration of the Orica Agreement contributed to an operating loss for the facility during 2015 of approximately $45 million compared to an operating loss of approximately $18 million in 2014.

Transportation Costs

Costs for transporting nitrogen based products can be significant relative to their selling price. For example, ammonia is a hazardous gas at ambient temperatures and must be transported in specialized equipment, which is more expensive than other forms of nitrogen fertilizers. In recent years, a significant amount of the ammonia consumed annually in the U.S was imported. Therefore, nitrogen fertilizers prices in the U.S. are influenced by the cost to transport product from exporting countries, giving domestic producers who transport shorter distances an advantage.

Climate Control Business

Construction Markets

Our Climate Control Business serves the new, renovation and replacement commercial/institutional and residential construction sectors. Over the past two years, our overall business volume has shifted from a new construction majority to a dominance in renovation and replacement projects today. Information available from the CMFS indicates that construction activity in the commercial/institutional markets we serve (including multi-family residential structures) is expected to increase 8%, 7% and 5% in the aggregate from 2016 - 2018 and has surpassed pre-recession levels collectively. In particular, the education, office and healthcare vertical end markets of the commercial/institutional sector are expected to grow faster than other vertical end markets we serve. Additionally, single-family residential construction is expected to grow 20% during 2016 to 805,000 units but still remains well below the 1.5 million unit pre-recession levels.

Based on the above forecasted growth in the vertical markets we serve as well as the introduction of new products specifically targeted at the hospitality, education and healthcare vertical markets, we expect the commercial/institutional portion of the Climate Control Business to experience sales growth in the medium and long-term. We believe that our residential products, which are all geothermal heat pumps (“GHP”), will experience limited sales growth, if any, due to the higher relative total system purchase cost of our higher efficiency GHP product offerings as compared to traditional HVAC systems. The higher initial purchase cost creates a longer payback period in most regions due to current low energy costs. We continue to concentrate our product development and sales and marketing efforts on increasing our share of the existing market for our products, as well as expanding the markets for and application of our products, with a focus on utilizing high efficiency/“green” technology.

Key Operational Factors

Chemical Business

Facility Reliability

Consistent, reliable and safe operations at our chemical plants are critical to our financial performance and results of operations. Unplanned downtime of the plants typically results in lost contribution margin, increased maintenance expense and decreased inventory for sale. The financial impact of planned downtime, including Turnarounds maintenance, is mitigated through a diligent planning process that takes into account, the availability of resources to perform the needed maintenance, feedstock logistics and other factors. Our Cherokee and Pryor Facilities have historically undergone a facility Turnaround every year. In the third quarter of 2014, our Cherokee Facility underwent an extended Turnaround replacing certain end-of-life equipment and performing additional maintenance required to move to a two-year Turnaround cycle. As a result, a Turnaround was not required at this facility during 2015 and we anticipate that Turnarounds at our Cherokee Facility typically will be performed every two years, and last 25 to 30 days. For the Cherokee Facility, the next bi-annual Turnaround is scheduled in mid-2016. Currently, Turnarounds at our Pryor Facility are performed annually, and typically last between 20 to 25 days. During the third quarter of 2015, the Pryor Facility completed a Turnaround that lasted 25 days. However, subsequent to the completion of this Turnaround, this facility experienced unplanned downtime as discussed below under “Items Affecting Comparability of Results.” We are currently anticipating a Turnaround at our Pryor Facility in mid-2016. At our El Dorado Facility, since we are able to perform Turnaround projects on individual plants without shutting down the entire facility, the impact of lost production is not significant. However, upon completion of the new ammonia plant at our El Dorado Facility, the facility will begin with annual Turnarounds that are expected to last between 20 to 25 days. All Turnarounds result in lost fixed overhead absorption and additional maintenance costs, which costs are expensed as incurred.

Prepay Contracts

We use forward sales of our fertilizer products to optimize our asset utilization, planning process and production scheduling. These sales are made by offering customers the opportunity to purchase product on a forward basis at prices and delivery dates that we propose. We use this program to varying degrees during the year depending on market conditions and depending on our view as to whether price environments will be increasing or decreasing. Fixing the selling prices of our products months in advance of their ultimate delivery to customers typically causes our reported selling prices and margins to differ from spot market prices and margins available at the time of shipment.

Climate Control Business

Product Orders, Sales and Ending Backlog

Our Climate Control Business had 2015 total bookings of $261 million, a 6% decline from 2014. This decline is directly related to the loss of Carrier’s water source heat pump contract that occurred in May 2014. The backlog at December 31, 2015 is approximately 4% higher than 2014 primarily driven by an increase in commercial/institutional branded water source heat pump products of our subsidiary, Climate Master, Inc. (“Climate Master”).

The following table shows information relating to our product order intake level, net sales and backlog of confirmed customer product orders of our Climate Control Business:

|  | New Orders (1) |  |  | Net Sales |  |  | Ending Backlog (1) |
|  | 2015 |  |  | 2014 |  |  | 2015 |  |  | 2014 |  |  | 2015 |  |  | 2104 |

(1) | Our product new order level consists of confirmed purchase orders from customers that have been accepted and received credit approval and 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 typically expect to ship substantially all of these orders within the next twelve months. At December 31, 2015 backlog includes two orders totaling approximately $1.5 million expected to ship from twelve to fifteen months. 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

33

| 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 2016, our new orders received were approximately $18.8 million and our backlog was approximately $65.6 million at January 31, 2016.

Operational Excellence Activities

In 2013 we began our Operational Excellence (“OpEx”) initiative at each of the companies within our Climate Control Business focusing on creating a safe work environment, industry leading quality, excellent customer service and operating cost reductions. Our OpEx focus intensified throughout 2014 and 2015 at our custom air handler business and realignment of our water source and geothermal heat pump and hydronic fan coil operations. We have increased our investment through the addition of a group Director of OpEx and staffing of OpEx professionals at three of our operations to accelerate improvements in the businesses. The Climate Control Business continues to build the foundation for the continuous improvement culture desired in our organization. OpEx initiatives will drive safety, quality, delivery, and cost reductions with integration into our 2016 strategic planning activities by setting targeted goals and driving organizational development and management accountability. Savings are expected to come from increased manufacturing excellence, effective launch of new products, and synergies gained through changes in organizational structure which will leverage support across all businesses.

Certain Heat Pump Contracts

In November 2013, Carrier advised Climate Master that heat pump contracts would not be renewed between Climate Master, as the manufacturer, and Carrier, as the purchaser. These contracts expired in May 2014. During 2014 and 2015, net sales pursuant to these heat pump contracts represented approximately $14.7 million and $0.6 million, respectively.

Consolidated Results for 2015

Our consolidated net sales for 2015 were $711.8 million compared to $761.2 million for 2014. The sales decrease of $49.4 million included a decrease of $55.5 million in our Chemical Business partially offset by an increase of $8.7 million in our Climate Control Business. Our consolidated operating loss was $50.8 million compared to a consolidated operating income of $53.4 million for 2014. The decrease in our operating results of $104.2 million included a decrease in our Chemical Business operating results of $93.1 million and a decrease of $1.8 million in operating income in our Climate Control Business. In addition, our unallocated corporate expenses increased $8.5 million. The items impacting our operating results are discussed in more detail below and under “Results of Operations.”

Items Affecting Comparability of Results

Property and Business Interruption Insurance Claims and Recoveries

In January 2014, we settled claims with our insurance carriers related to property damage and business interruption at our Cherokee Facility. For 2014, the impact of these claims to our operating results was approximately $22.9 million recognized as a reduction to cost of sales and $5.1 million recognized as a property insurance recovery in excess of losses incurred.

Impairment of Natural Gas Properties and Long Lived Assets

During 2015, a subsidiary within our Chemical Business received an engineering and economic evaluation (the “Evaluation”) from our independent petroleum engineer relating to its working interest in natural gas properties in the Marcellus Shale region. The results of the Evaluation indicated that the carrying amount of these natural gas properties may not be recoverable. Therefore a review for impairment was performed on these natural gas properties. As a result of the review, our Chemical Business recognized a non-cash impairment charge of $39.7 million to write-down the carrying value of our working interest in these natural gas properties to the estimated fair value of $22.5 million at the time of the evaluation. In addition, our Chemical Business recognized a $3.5 million non-cash impairment charge to reduce the carrying value of certain plant assets related to unused ammonia production equipment at our Pryor Facility. See additional discussion below under “Critical Accounting Policies and Estimates” in this MD&A.

Pryor Downtime

Our Pryor Facility completed an annual Turnaround on August 4, 2015, which lasted 25 days. While restarting the plant, several mechanical issues were encountered requiring management to take the plant out of service for additional repairs. The plant was restarted and resumed production on September 23, 2015, resulting in 45 days of unplanned downtime. The Pryor facility experienced additional unplanned downtime in its Urea and UAN plants during the fourth quarter of 2015. We estimate that the period of planned

34

and unplanned downtime at our Pryor Facility during the third quarter of 2015 resulted in reduced sales volumes of UAN and ammonia by approximately 18,300 tons and 22,200 tons, respectively and an additional reduction in UAN sales volumes of 21,000 tons in the fourth quarter. The impact from these outages increased our operating losses in 2015 by approximately $19 million, which includes unabsorbed overhead expenses, costs of repair and lost profit margin.

During the first six months of 2014, Pryor incurred unplanned downtime resulting in lost ammonia and UAN production of approximately 34,000 tons and 59,000 tons respectively. The estimated negative impact to operating income resulting from these outages was approximately $15 million. In addition, Pryor incurred a short planned 8 day outage in July to perform maintenance and experienced a 10 day unplanned outage in August resulting from a power outage.

Orica Agreement

EDC’s LDAN sales agreement with Orica expired on April 9, 2015. The Orica Agreement included a provision for Orica to pay for fixed overhead costs and gross profit on the portion of the annual minimum of product not taken. The annual fixed overhead and gross profit associated with the 240,000 tons was approximately $20 million. As a result during 2015, our El Dorado Facility had approximately $15 million less contribution margin from this agreement compared to 2014.

Subsequent to the expiration of the Orica Agreement, we continue to selling LDAN to other customers including Orica but at a lower volume given that we remain a high cost producer due to purchasing ammonia as the feedstock. We believe we will continue to experience lower volumes until the El Dorado ammonia plant construction is in production which is expected to begin early in the second quarter of 2016.

We have signed contracts with customers that, beginning in January 2016, provide for the sale of LDAN for approximately 150,000 tons annually under various cost plus pricing arrangements. With the recent downturn in the mining industry, we are unsure if we will reach these sales levels. Unlike the Orica Agreement, which contained take-or-pay provisions, certain of these contracts include minimum annual volume levels with penalty payments if minimum volumes are not met. However, as discussed in more detail above under “Key Industry Factors,” our LDAN sales volumes are being impacted by the decline in coal production in the U.S.

Cherokee Turnaround Expense

In 2014 our Cherokee Facility underwent an extended Turnaround replacing certain end-of-life equipment and performing additional maintenance required to move to a two-year Turnaround cycle. The impact from this turnaround reduced our operating results in 2014 by approximately $5 million which includes unabsorbed overhead expenses, costs of repair and lost profit margin. Our Cherokee Facility has moved to a bi-annual turnaround schedule with the next Turnaround scheduled for third quarter of 2016.

Interest Expense, net

For 2015 and 2014, interest expense was $7.4 million and $21.6 million, net of capitalized interest of $30.6 million and $14.1 million, respectively. Interest was capitalized based upon construction in progress of the El Dorado Expansion and certain other capital projects.

Certain Unallocated Corporate Expenses

During 2015, we incurred certain one-time corporate costs relating to severance agreements with former executives of $2.0 million and we incurred stock-based compensation of $0.4 million associated with our Chief Executive Officer relating to restricted stock that vested on the date of grant, and certain Board fees of $0.2 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, 2015, 2014, and 2013 and accompanying notes and the discussions under “Overview” and “Liquidity and Capital Resources” included in this MD&A. See discussion in Note 1 to Consolidated Financial Statements regarding the adjusted prior period amounts to classify certain shipping and handling of our Chemical Business from net sales and SG&A to cost of sales to conform to our current presentation of our consolidated statement of operations for 2015.

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

35

represents net sales less cost of sales. Operating income (loss) 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.

Net Sales – Chemical

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 majority 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. In general, for 2015 our agricultural sales were lower due to lower sales volumes for HDAN, ammonia and our other agricultural products due to unusually wet application seasons and lower prices for HDAN and UAN partially offset by higher UAN sales volumes. Mining sales also declined primarily due to lower sales prices and volumes while sales of industrial products

37

decreased slightly with lower prices partially offset by higher sales volumes. In addition, natural gas sales prices and volumes declined in 2015 compared to 2014.

| · | Agricultural products comprised approximately 49% and 48% of the Chemical Business net sales for 2015 and 2014, respectively. The sales decline of 8.8% over 2014 sales was driven by a slight overall decline in sales volumes with lower HDAN, ammonia and other agricultural products sales volumes partially offset by higher UAN sales volumes. The higher UAN sales volumes were primarily due to higher production at our Cherokee and Pryor Facilities in 2015 compared to 2014 when we performed a bi-annual turnaround at the Cherokee Facility. Compounding the slight decline in sales volumes was a decrease in our average product selling prices per ton in 2015 with UAN down 9% and HDAN down 1%. These lower selling prices were attributable to lower natural gas and other commodity prices coupled with lower urea selling prices caused by the large amount of imports, placing downward pressure on selling prices. Ammonia prices were essentially unchanged for 2015 compared to 2014.

| · | Industrial acids and other chemical products sales increased as a result of increased volumes at the Baytown Facility (which performed a Turnaround in 2014, but not in 2015) and at our Cherokee Facility, partially offset by lower prices from the pass-through of decreased ammonia costs to contractual customers and lower volumes from the El Dorado Facility due to lower customer demand.

| · | Mining products sales decreased primarily due to lower sales of LDAN resulting from the expiration of the take-or-pay Orica Agreement in April 2015 compared to the contract being in place for the full year in 2014 and lower sales volumes for the balance of 2015 due to being a high cost producer and not competitive in the marketplace. Additionally, lower sales volumes of AN solution at our Cherokee Facility are the result from a continued decline of demand for mining products in the Appalachian region combined with lower selling prices contributed to lower mining sales.

| · | Other products relates to natural gas sales from our working interests in certain natural gas properties. The decrease in natural gas sales is due to lower realized sales prices out of the Marcellus Shale region combined with lower production volumes in 2015 compared to 2014 as the operator of these properties has slowed development due to the decline in natural gas sales prices.

Gross Profit - Chemical

| · | Our gross profit decreased $44.4 million in 2015 when compared to 2014. Excluding the business interruption insurance recoveries of $22.9 million in 2014, the decrease in gross profit in 2015 compared to 2014 was $21.5 million. The decrease of $21.5 million was primarily due to the loss of the margin contribution relating to the expiration of the Orica Agreement, lost absorption of fixed overhead costs associated with lower production of HDAN, lower average sales prices, increased operating costs including railcar lease costs, partially offset by the higher overall on-stream rate at the Cherokee Facility and lower natural gas feedstock costs. Natural gas feedstock costs decreased approximately 25% but that was partially offset by operating losses incurred relating to our working interests in certain natural gas properties.

Operating Income (Loss) - Chemical

| · | Our Chemical Business operating loss was $41.8 million, a decrease of $93.1 million in operating results. This decrease includes the $43.2 million non-cash impairment charges consisting of an impairment charge of $39.7 million to reduce the carrying value of our working interest in natural gas properties and a $3.5 million impairment charge to reduce the carrying value of certain plant assets related to unused ammonia production equipment at our Pryor Facility during 2015. In addition to the business interruption insurance recovery included in gross profit discussed above, a property insurance recovery of $5.1 million for a total insurance recovery of $28.0 million, was recognized in 2014. Excluding the impairment charges of $43.2 million in 2015 and the total insurance recoveries of $28.0 million in 2014, operating results decreased $21.9 million primarily from the decrease in gross profit discussed above and personnel and training expenses, which are primarily related to the expansion related activities at the El Dorado Facility.

Net Sales – Climate Control

| · | Net sales of our water source and geothermal heat pump products decreased in 2015 primarily as a result of the loss of the Carrier heat pump contract, which generated $14.7 million in sales in 2014 compared to $0.6 million in 2015. Excluding Carrier heat pump sales, commercial/institutional product sales of water source and geothermal heat pumps improved slightly over 2014 while residential product sales of water source and geothermal heat pumps declined $3.9 million, or 10.0%. Overall, the number of units sold declined and the average unit selling price decreased due to lower Carrier sales and product mix, respectively. From a commercial/institutional market perspective, gains were seen in the multi-family, healthcare and public building sectors with a slight decline in the education and office sectors. We believe during 2015, we continued to maintain a leading market share position based on market data supplied by AHRI.

| · | Net sales of our hydronic fan coils increased in 2015 primarily due to favorable end markets as well as new product introductions and an increase in selling prices relative to 2014. Sales gains were realized in hospitality, healthcare, government buildings and multi-family offset slightly by a drop in the education market. We believe during 2015, we continued to maintain a leading market share position based on market data supplied by AHRI.

| · | Net sales of our other HVAC products increased primarily due to increased sales of our large custom air handlers related to a higher beginning backlog entering 2015. Our backlog continues to grow.

Gross Profit - Climate Control

| · | The increase in gross profit in our Climate Control Business was primarily the result of the higher net sales as discussed above, although the gross profit as a percentage of net sales declined due to product mix and under absorbed overhead and increased expenses for contract labor, outside services, recruiting, repair and maintenance.

Operating Income - Climate Control

| · | Operating income decreased primarily as a result of higher variable selling expenses related to the increase in sales volume (freight, warranty, and commissions) partially offset by a reduction in fixed expenses in 2015 over 2014, primarily advertising.

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. General corporate expenses were $29.9 million in 2015 compared to $21.4 million in 2014. The increase of approximately $8.5 million primarily relates to an increase of $6.4 million for personnel related expenses including; one-time severance payments of approximately $2.0 million for certain senior executives, additional compensation expense of approximately $1.0 million, discontinuance of the allocation of certain senior management costs to the Chemical and Climate Control Businesses of approximately $1.2 million and compensation related to restricted stock awards of approximately $0.4. The remaining increase of approximately $2.1 million relates primarily to an increase in professional fees for legal and investment banking services related to various financing activities, an increase in auditing and other accounting services and other consulting services. Additionally, in both 2014 and 2015 we incurred $4.8 million and $4.6 million respectively for fees and expenses related to analyzing proposals received from certain activist shareholders and in dealing, negotiating and settling with those shareholders in order to avoid a proxy fight.

Interest Expense, net

Interest expense for 2015 was $7.4 million compared to $21.6 million for 2014. The decrease is due primarily to capitalized interest on capital projects under development and construction, of which $30.6 million was capitalized in 2015 compared to $14.1 million during 2014.

Provision (benefit) for Income Taxes

The benefit for income taxes for 2015 was $23.6 million compared to a provision of $12.4 million for the same period in 2014. The effective tax rate was 40% for 2015 and 39% for 2014.

Net Sales – Chemical

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. 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 2014 production and sales volumes were higher in all three of our primary markets due to consistent customer demand and improved on-stream production rates at the El Dorado, Pryor and Cherokee Facilities, partially offset by an extended Turnaround in the third quarter and the approximately 30 days of downtime in the fourth quarter to complete certain unplanned maintenance at our Cherokee Facility.

| · | Agricultural products comprised approximately 48% and 45% of the Chemical Business’ net sales for 2014 and 2013, respectively. Agricultural products sales increased in 2014 as more product was available to sell resulting from the increased on-stream rates of our facilities partially offset by lower average selling prices for nitrogen fertilizers. Compared to 2013, the 2014 average agricultural products selling prices per ton were lower by 8%, 5%, and 10% for ammonia, UAN and AN, respectively. The decrease in selling prices for the nitrogen fertilizers was due largely to record exports of urea from China combined with lower commodity prices.

| · | Industrial acids and other chemical products sales increased in 2014 as a result of more product available to sell due to the improved on-stream rates of our chemical facilities.

| · | Mining products sales increased in 2014 primarily as a result of more product available to sell due to the improved on-stream rates of our chemical facilities.

| · | Other products relates to natural gas sales from our working interests in certain natural gas properties acquired in 2012 and 2013 by a subsidiary within our Chemical Business. The increase in natural gas sales is primarily due to higher production volume as these properties are developed and partially offset by lower net selling prices.

Gross Profit - Chemical

| · | Our gross profit increased $20.4 million in 2014 when compared to 2013. Excluding business interruption insurance recoveries of $22.9 million and $28.6 million in 2014 and 2013, respectively, and $4.5 million of precious metals recovery in 2013, the increase in gross profit was $30.6 million. The increase of $30.6 million was due to the higher sales level resulting in improved fixed overhead absorption made possible by the improved on-stream production rates of our chemical facilities. The improved gross profit was partially offset by a decline in the margin per ton of nitrogen fertilizers due to lower selling prices and higher feedstock costs. Natural gas feedstock cost increased approximately 12% partially offset by a 7% decrease in ammonia feedstock costs, while AN prices decreased 10% and UAN selling prices decreased 5%, negatively affecting gross profit margins on our nitrogen fertilizer sales.

| · | Unrealized losses related to forward contracts on natural gas purchases decreased 2014 gross profit by $2.1 million compared to a minimal unrealized gain in 2013.

| · | Purchased UAN that was sold at a loss to honor forward sales commitments in excess of available production due to unplanned downtime reduced gross profit by $1.2 million in 2014.

Operating Income - Chemical

| · | Our Chemical Business’ operating income was $51.3 million, a decrease of $36.5 million. In addition to the business interruption insurance recoveries included in gross profit discussed above, property insurance recoveries of $5.1 million and $66.0 million were recognized in 2014 and 2013, respectively. Excluding all insurance recoveries of $28.0 million and $94.6 million in 2014 and 2013, respectively, and excluding the precious metals recovery of $4.5 million in 2013, our adjusted operating income was $23.3 million in 2014 compared to an adjusted operating loss of $11.3 million, or an increase of $34.6 million. Additionally net other expenses were $4.0 million lower in 2014 due primarily to dismantling expenses and penalties incurred in 2013.

(1) | As a percentage of net sales

Net Sales – Climate Control

| · | Net sales of our water source and geothermal heat pump products decreased in 2014 primarily as a result of the loss of the Carrier heat pump contracts, which generated sales in 2014 that were $17 million lower than 2013. Excluding Carrier heat pump sales, commercial/institutional product sales were flat with 2013 while residential product sales were up nearly 6.5%. Overall, the number of units sold declined; and the unit average unit selling price increased due to lower Carrier sales. From a commercial/institutional market perspective, gains were seen in the retail and multi-family sectors with a slight decline in the education sector. In addition, 2014 had an extremely slow start due to low beginning backlog and weather related delays. Incoming orders, excluding Carrier, for commercial/institutional products and residential products increased 11% and 15%, respectively. During 2014, we continued to maintain a market share leadership position based on market data supplied by AHRI.

| · | Net sales of our hydronic fan coils declined in 2014 primarily due to lower than expected product orders partially offset by an increase in selling prices of approximately 8% over 2013 primarily due to product and feature mix. We experienced only minor fluctuations in the vertical markets served. During 2014, we continued to maintain a market share leadership position based on market data supplied by AHRI.

| · | Net sales of our other HVAC products decreased primarily due to a lower beginning backlog entering 2014, customer scheduled delivery dates shifting out for our large custom air handlers and modular chillers, partially offset by increased activity on contracts for our engineering and construction services.

Gross Profit - Climate Control

| · | The decrease in gross profit in our Climate Control Business was primarily the result of the lower net sales as discussed above and reduced overhead absorption related to fewer units sold in 2014 as compared to 2013.

Operating Income - Climate Control

| · | Operating income decreased primarily as a result of the lower gross profit discussed above, partially offset by lower operating expenses. However, variable selling expenses as a percentage of sales increased due to the change in product and customer mix with lower OEM sales at CM causing freight to increase as a percentage of sales and warranty expenses increasing due to recent claims at our fan coil operation. Fixed selling and administrative expense in 2014 declined slightly from 2013 but represented a greater percentage of net sales due to lower sales in 2014.

General Corporate Expenses

General corporate expenses were $21.4 million during 2014 compared to $14.6 million in 2013. The increase was primarily the result of incurring approximately $4.2 million in fees and expenses related to evaluating and analyzing proposals from and settling with certain activist shareholders in the first quarter of 2014 and increases in consulting fees and services of $0.9 million, insurance and bank related expense of $0.4 million, depreciation and amortization of $0.4 and personnel costs of $0.3 million. During 2013, we recognized other income of $0.5 million relating to a litigation settlement.

42

Interest Expense, net

Interest expense for 2014 was $21.6 million compared to $14.0 million for 2013. The increase is due primarily to the issuance of the 7.75% Senior Secured Notes during 2013, partially offset by $14.1 million of capitalized interest on capital projects under development and construction during 2014 compared to $4.0 million capitalized during 2013.

Loss on Extinguishment of Debt

As the result of the payoff of a secured term loan facility 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 2014 was approximately $12.4 million compared to $35.4 million for 2013. The resulting effective tax rate was 39% for 2014 and 40% for 2013 (excluding the benefit of $0.5 million associated with the retroactive tax relief on certain 2012 tax provisions that expired in 2012). The decrease in the effective tax rate was due primarily to certain expired tax credits reinstated during December 2014.

LIQUIDITY AND CAPITAL RESOURCES

For 2015, our operating activities generated positive cash flows. The following summarizes our cash flow for all activities:

Cash Flow from Continuing Operating Activities

For 2015, net cash provided by continuing operating activities was $31.6 million primarily as the result of net loss of $34.8 million plus adjustments of $43.2 million for the impairment of long-lived assets (primarily natural gas properties), $18.5 million for deferred income taxes, and $40.5 million for depreciation, depletion and amortization of PP&E.

Cash Flow from Continuing Investing Activities

For 2015, net cash used by continuing investing activities was $354.0 million consisting primarily of $439.8 million used for expenditures for PP&E primarily for the benefit of our Chemical Business, partially offset by net proceeds of $85.5 million from restricted cash and cash equivalents and investments primarily representing funds designated by management for specific capital projects relating to our Chemical Business.

Cash Flow from Continuing Financing Activities

For 2015, net cash provided by continuing financing activities was $263.1 million and primarily consisted of net proceeds from the issuance of preferred stock and warrants of $198.6 million and net proceeds from long-term financing of $79.0 million, partially offset by net payments on short-term financing and payment of long-term debt of $16.6 million.

Liquidity Needs for 2016

As discussed below under “Capitalization”, our primary cash needs relate to completing our current capital projects in addition to our scheduled debt and preferred dividend and redemption requirements. Our cash requirements are primarily dependent on credit agreements, various forms of financing, and through internally generated cash flows. See “Key Capital Expenditure, Financing and Other Developments - 2015.”

During 2016, we will complete the construction of and begin operations at the new ammonia plant being constructed at our El Dorado Facility. We plan to fund our remaining cash needs to complete this project along with our annual interest payments on our outstanding debt, our dividend payments on our outstanding preferred stock and the repayment of the Secured Promissory Note due 2016 through funds received in connection with the $260 million in financing completed in December 2015, cash flow from operations, the funding of the cogeneration facility equipment at our El Dorado Facility and the use of our revolving credit facility. We have the ability to accrue the dividend payments on our preferred stock should we need to elect that option.

Our Senior Secured Notes mature in 2019 and the holders of our Series E Redeemable Preferred and Series F Redeemable Preferred have the right to have the Company redeem that preferred stock in 2019, including accumulated dividends, if any. We intend to seek refinancing on or before the maturity date in 2019 of the Senior Secured Notes. If the holders of our Series E Redeemable Preferred and Series F Redeemable Preferred require us to redeem the preferred stock in 2019, we may be required to seek additional financing.

As of December 31, 2015, our cash and cash equivalents were $127.3 million. In addition, our $100 million revolving credit facility was undrawn and available to fund operations as discussed below, if needed, subject to the amount of our eligible collateral and outstanding letters of credit.

As discussed in “Key Capital Expenditure, Financing and Other Developments - 2015,” over the course of 2015, management in conjunction with the owner’s representative, the engineering, procurement and construction contractor and other consultants determined that the total cost to complete the El Dorado Expansion would exceed what we previously projected compared to earlier estimates. We have now determined that the total cost to complete the El Dorado Expansion is estimated to be in the range of $831 million to $855 million ($705 million spent as of December 31, 2015 and $126 million to $150 million to be spent in 2016).

In order to finance these additional costs, and for the reasons discussed in “Key Capital Expenditure, Financing and Other Developments - 2015,” during the fourth quarter of 2015, we obtained additional financing totaling $260 million in the form of debt, preferred stock, and common stock warrants. We believe that the funding provided by the financing, together with our other sources of liquidity, will be sufficient for our anticipated liquidity needs through completion of the El Dorado Expansion.

In February 2016, we received financing of $10 million related to the cogeneration facility equipment in connection with the El Dorado Expansion projects. Our agreement allows us to secure up to an additional $10 million in financing on the cogeneration facility equipment.

We are party to the Senior Secured Notes Indenture governing the 7.75% Senior Secured Notes and the Senior Secured Note Purchase Agreement governing the 12% Senior Secured Notes. The Senior Secured Notes Indenture and the Senior Secured Note Purchase Agreement contain covenants that, among other things, limit LSB’s ability, with certain exceptions and as defined in the Senior Secured Notes Indenture and the Senior Secured Note Purchase Agreement, to enter certain transactions.

We and certain of our subsidiaries are party to the Amended Working Capital Revolver Loan. Pursuant to the terms of the facility, the principal amount LSB and certain of its subsidiaries (“the Borrowers”) may borrow is up to $100.0 million, based on specific percentages of eligible accounts receivable and inventories. At December 31, 2015, there were no outstanding borrowings under the Amended Working Capital Revolver Loan and the net credit available for borrowings was approximately $64.4 million, based on our eligible collateral, less outstanding letter of credit as of that date.

Capital Additions

Capital Additions - 2015

Capital additions during 2015 were $477.0 million, including $473.4 million for the benefit of our Chemical Business. The Chemical Business capital additions included $443.0 million for expansion projects at our El Dorado Facility (which capital additions include

44

equipment associated with maintaining compliance with environmental laws, regulations and guidelines), $19.1 million for various major renewal and improvement projects, $6.0 million relating to the new ERP system, $3.7 million for the development of natural gas leaseholds, and an additional $3.7 million associated with maintaining compliance with environmental laws, regulations and guidelines not associated with the El Dorado Expansion. The capital additions were funded primarily from noncurrent restricted cash and investments, third-party financing and working capital. Due to the increase in the amount of capital additions incurred and planned, our depreciation, depletion and amortization expenses have increased and are expected to increase in 2016.

(1) | Includes cost associated with renewal and improvement projects, environmental projects and the development of natural gas leaseholds, some of which may be deferred.

(2) | Includes cost associated with savings initiatives, new market development, and other capital projects.

Included in planned capital expenditures is capitalized interest of approximately $12 million for 2016. The planned capital expenditures for Corporate and Other are primarily for the replacement of our ERP, financial and operations management system. The new ERP system replaces our legacy systems, which are out-of-date and largely unsupported, and will improve our access to operational and financial information utilized to manage the business and improve our security and regulatory compliance capability. This project began in 2013 and is expected to be fully implemented in 2017 at a total cost of $26 million to $28 million.

Planned capital expenditures are presented as a range to provide for engineering estimates, the status of bidding, variable material costs, unplanned delays in construction, and other contingencies. As the engineering, design, and bidding processes progress and project construction proceeds, the estimated costs are more certain and the range of estimates narrows. The planned capital expenditures include investments that we anticipate making for expansion and development projects, environmental requirements, and major renewal and improvement projects. Beyond the completion of the expansion projects, specific capital projects are less identified but are expected to include between $40 million to $60 million per year at our chemical facilities for ongoing capital maintenance, including environmental compliance, major renewal and improvement projects, and other capital projects, and approximately $19 million from 2016-2019 to fully develop our natural gas working interests.

The El Dorado Expansion

The El Dorado Facility has certain expansion projects underway, of which a portion of these have been completed. These expansion projects include an ammonia production plant; a new 65% strength nitric acid plant and concentrator; and other support infrastructure, all of which were analyzed and evaluated based on their forecasted return on investment. The expected costs of these projects are outlined below, and their planned amounts are included in the table above.

Our El Dorado Facility produces nitric acid, HDAN and LDAN from purchased ammonia, which is currently at a cost disadvantage compared to products produced from natural gas. The El Dorado Facility historically purchased 600-700 tons of ammonia per day when operating at full capacity. We are constructing a 1,150 ton per day ammonia production plant at the El Dorado Facility, which we believe will eliminate the cost disadvantage, increase capacity, and improve efficiency of the El Dorado Facility. This plant is expected to be operational early in the second quarter of 2016.

During 2015, we have completed the construction of a new 1,100 ton per day, 65% strength nitric acid plant and concentrator that replaces the concentrated nitric acid capacity lost in 2012. The nitric acid plant and concentrator are designed to be more efficient and provide increased nitric acid production capacity.

As a result of the increased production capacity at the El Dorado Facility, it is necessary to expand and improve certain support infrastructure, including utility capacity, control room facilities, inventory storage and handling, and ammonia distribution. Also, other cost reduction and cost recovery equipment, including an electric cogeneration plant, are being added to improve efficiency and lower the cost of production.

As the result of the completion/expected completion of the various capital projects included in the El Dorado Expansion (ending the capitalization of interest to these capital projects) and the issuance of the 12% Senior Secured Notes, our future operating results will be impacted by an increase in interest expense.

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 $5.5 million in 2015 in connection with environmental projects. For 2016, we expect to incur expenses ranging from $4.5 million to $5.5 million in connection with additional environmental projects. However, it is possible that the actual costs could be significantly different than our estimates.

Dividends

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 has not made a decision whether or not to pay such dividends on our common stock in 2016. Also see discussion below concerning certain limitations relating to paying dividends on our common stock.

During the first quarter of 2015, annual dividends totaling $300,000 were declared on our outstanding Series D 6% cumulative convertible Class C preferred stock (the “Series D Preferred”) and Series B 12% cumulative convertible Class C Preferred Stock (the “Series B Preferred”) and subsequently paid in 2015 using funds from our working capital. Each share of preferred stock is entitled to receive an annual dividend, only when declared by our Board, 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.

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

Dividends on the Series E Redeemable Preferred are cumulative and payable semi-annually, commencing May 1, 2016, in arrears at the annual rate of 14% of the liquidation value of $1,000 per share. Each share of Series E Redeemable Preferred is entitled to receive a semi-annual dividend, only when declared by our Board, of $70.00 per share for the aggregate semi-annual dividend of $14.7 million. In addition, dividends in arrears at the dividend date, until paid, shall compound additional dividends at the annual rate of 14%. We also must declare a dividend on the Series E Redeemable Preferred on a pro rata basis with our common stock. As long as the Purchaser holds at least 10% of the Series E Redeemable Preferred, we may not declare dividends on our common stock and other preferred stocks unless and until dividends have been declared and paid on the Series E Redeemable Preferred for the then current dividend period in cash. As of December 31, 2015, the amount of accumulated dividends on the Series E Redeemable Preferred was approximately $2.3 million.

Compliance with Long - Term Debt Covenants

As discussed below under “Loan Agreements”, 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

46

next twelve months. We plan to use our revolving credit facility to fund operational needs though out 2016 and believe that even with this additional borrowing that we will meet the minimum fixed charge coverage ratio during 2016.

Loan Agreements and Redeemable Preferred Stock

Senior Secured Notes - In 2013, LSB sold $425 million aggregate principal amount of the 7.75% Senior Secured Notes due 2019. The 7.75% 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 on February 1st and August 1st.

On November 9, 2015, LSB sold $50 million aggregate principal amount of the 12% Senior Secured Notes due 2019 in a private placement exempt from registration under the Securities Act of 1933, as amended. The 12% Senior Secured Notes bear interest at the annual rate of 12% and mature on August 1, 2019. Interest is to be paid semiannually on February 1st and August 1st, which began February 1, 2016. The 12% Senior Secured Notes are secured on a pari passu basis with the same collateral securing LSB’s existing $425 million aggregate principal amount of 7.75% Senior Secured Notes issued in 2013. The 12% Senior Secured Notes have covenants and events of default that are substantially similar to those applicable to the 7.75% Senior Secured Notes.

See footnote (B) under Note 9 to Consolidated Financial Statements included in this report for additional information on these Senior Secured Notes.

Amended Working Capital Revolver Loan – LSB and certain of its subsidiaries are party to the Amended Working Capital Revolver Loan, by which the Borrowers may borrow on a revolving basis up to $100.0 million, based on specific percentages of eligible accounts receivable and inventories. 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, 2015, the interest rate was 4.0% based on LIBOR. Interest is paid monthly, if applicable.

At December 31, 2015, there were no outstanding borrowings under the Amended Working Capital Revolver Loan. At December 31, 2015, the net credit available for borrowings under our Amended Working Capital Revolver Loan was approximately $64.4 million, based on our eligible collateral, less outstanding letters of credit as of that date.

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. If applicable, this ratio will be measured monthly on a trailing twelve month basis and as defined in the agreement. As of December 31, 2015, as defined in the agreement, the fixed charge coverage ratio was 2.3 to 1. See footnote (A) under Note 9 of Notes to Consolidated Financial Statements included in this report for additional information on this loan.

Secured Promissory Note due 2016 - 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 followed 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 maturity date was amended on January 5, 2015 from February 1, 2016 to April 1, 2016.

Principal and interest are payable in two monthly installments totaling approximately $1.3 million with interest based on the LIBOR rate plus 300 basis points with a final balloon payment of approximately $14.0 million due at maturity. The interest rate at December 31, 2015 was 3.42%. The loan is secured by the Working Interests and related properties and proceeds.

Secured Promissory Note due 2019 - On February 5, 2016, EDC entered into a secured promissory note due 2019 for an original principal amount of $10.0 million. The secured promissory note due 2019 bears interest at the rate of 5.73% per annum and matures on June 29, 2019. Principal and interest are payable in 40 equal monthly installments with a final balloon payment of approximately $6.7 million. The Secured Promissory Note due 2019 is secured by the cogeneration facility equipment and is guaranteed by LSB.

Secured Promissory Note due 2021 - On April 9, 2015, EDC and a lender entered into a secured promissory note due 2021 for an original principal amount of approximately $16.2 million. The Secured Promissory Note due 2021 bears interest at the rate of 5.25% per year and matures on March 26, 2021. Interest only is payable monthly for the first 12 months of the term. Principal and

47

interest are payable monthly for the remaining term of the Secured Promissory Note due 2021. This Secured Promissory Note due 2021 is secured by a natural gas pipeline being constructed at the El Dorado Facility and is guaranteed by LSB.

Secured Promissory Note due 2022 - On September 16, 2015, El Dorado Ammonia L.L.C. (“EDA”), a subsidiary within our Chemical Business, entered into a secured promissory note due 2022 for the construction financing of an ammonia storage tank and related systems with an initial funding received of $15.0 million and a maximum principal note amount of $19.8 million. The remainder of the funding under the Secured Promissory Note due 2022 is expected to be drawn upon completion of the ammonia storage tank, but in any event by May 2016 (the “Loan Conversion Date”). Up to the Loan Conversion Date, EDA will make monthly interest payments on the outstanding principal borrowed.

On the Loan Conversion Date, the outstanding principal balance will be converted to a seven year secured term loan requiring equal monthly principal and interest payments. In addition, a final balloon payment equal to the remaining outstanding principal (or 30% of the outstanding principal balance on the Loan Conversion Date) is required on the maturity date. The Secured Promissory Note due 2022 bears interest at a rate that is based on the monthly LIBOR rate plus 4.0% and matures in May 2022. At December 31, 2015, the interest rate was 4.24%. The Secured Promissory Note due 2022 is secured by the ammonia tank and related systems and is guaranteed by LSB.

Redemption of Series E Redeemable Preferred - At any time on or after August 2, 2019, each Series E Holder has the right to elect to have such holder’s shares redeemed by LSB at a redemption price per share equal to the Liquidation Preference of such share as of the redemption date. The Series E Redeemable Preferred has a liquidation preference per share of $1,000 plus accrued and unpaid dividends plus the participation rights value (the “Liquidation Preference”). Additionally, LSB, at its option, may redeem the Series E Redeemable Preferred at any time at a redemption price per share equal to the Liquidation Preference of such share as of the redemption date. Lastly, with receipt of (i) prior consent of the electing Series E holder or a majority of shares of Series E Redeemable Preferred and (ii) all other required approvals, including under any principal U.S. securities exchange on which our common stock is then listed for trading, LSB can redeem the Series E Redeemable Preferred by the issuance of shares of common stock having an aggregate common stock price equal to the amount of the aggregate Liquidation Preference of such shares being redeemed in shares of common stock in lieu of cash at the redemption date.

In the event of liquidation, the Series E Redeemable Preferred is entitled to receive its Liquidation Preference before any such distribution of assets or proceeds is made to or set aside for the holders of our common stock and any other Junior Stock. In the event of a change of control, we must make an offer to purchase all of the shares of Series E Redeemable Preferred outstanding.

Since carrying values of the redeemable preferred stocks are being increased by periodic accretions (including the amount for dividends earned but not yet declared or paid) so that the carrying amount will equal the redemption value as of August 2, 2019, the earliest possible redemption date by the holder, this accretion has and will continue to impact income (loss) per common share.

Seasonality

See discussion above under “Part I-Item 1 Business” for seasonality trends.

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.

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, 2015, we have agreed to indemnify the sureties for payments, up to $17.3 million, made by them in respect of such bonds. All of these insurance bonds are expected to expire or be renewed in 2016.

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. It is reasonably possible that the estimates and assumptions utilized as of December 31, 2015 could change in the near term. The more critical areas of financial reporting impacted by management's judgment, estimates and assumptions include the following:

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.

During September 2015, our Chemical Business recognized an impairment charge of $39.7 million to write-down the carrying value of our working interest in natural gas properties in the Marcellus Shale region to their estimated fair value of $22.5 million. The impairment charge represented the amount by which the carrying value of these natural gas properties exceeded the estimated fair value and was therefore not recoverable. The estimated fair value was determined based on estimated future discounted net cash flows, a Level 3 input, using estimated production and prices at which we reasonably expect natural gas will be sold, including the Evaluation provided by our independent consulting petroleum engineer in October 2015. The impairment was due to the decline in prices for natural gas futures, large natural gas price differentials in the Marcellus Shale region and changes in the drilling plans of these natural gas properties that caused certain of these properties to be reclassified from the “proved undeveloped reserves” category to the “probable undeveloped resources” category included in the Evaluation because those properties are no longer likely to be developed within five years.

In addition during December 2015, our Chemical Business recognized an impairment charge of $3.5 million to write down the carrying value of certain plant assets related to certain ammonia production equipment at our Pryor Facility. The estimated fair value was determined based on an offer received from a possible buyer less estimated costs that would be incurred if the equipment is sold (Level 3 inputs).

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 and long 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.

Since 2003, our residential products warranty carried a ten-year standard parts warranty on the refrigerant circuit (including air coils, compressors, thermal expansion valves, water coils, and reversing valves) and five-years on the other components (motors being the major component). In 2010, the warranty policy was amended to include a full ten-year standard parts and five-year standard labor warranty. Without a full ten-year experience on the other components (motors), there is a risk we could incur higher than projected warranty costs over the next five years.

50

At December 31, 201 5 and 201 4, our accrued product warranty obligations were $10.6 million and $8.8 million, respectively and are included in current and noncurrent accrued and other liabilities in the consolidated balance sheets. For 201 5, 201 4, and 201 3, our warranty expense was $9.6 million, $7.9 million, and $7.4 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 involved in various legal matters that require management to make estimates and assumptions, including costs relating to the lawsuit styled City of West, Texas v CF Industries, Inc., et al, discussed under “Other Pending, Threatened or Settled Litigation” of Note 11 to Consolidated Financial Statements included in this report. It is possible that the actual costs could be significantly different than our estimates.

Regulatory Compliance – As discussed under “Environmental, Health and Safety Matters” in Item 1 of this report, 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. However, certain conditions exist which may result in a loss but which will only be resolved when future events occur relating to these matters. We are involved in various environmental matters that require management to make estimates and assumptions, including our current inability to develop a meaningful and reliable estimate (or range of estimate) as to the costs relating to a corrective action study work plan approved by the KDHE discussed under footnote 3 – Other Environmental Matters of Note 11. At December 31, 2015, liabilities totaling $0.4 million have been accrued relating to these issues as discussed. This liability is included in current accrued and other liabilities and is based on current estimates that may be revised in the near term. At the time that cost estimates for any corrective action are received, we will adjust our accrual accordingly. I t is possible that the adjustment to the accrual and the actual costs could be significantly different than our current estimates.

Redeemable Preferred Stocks and Warrants – On December 4, 2015, we issued the Series E and F Redeemable Preferred and Warrants. The redeemable preferred stocks are redeemable outside of our control and are classified as temporary/mezzanine equity on our consolidated balance sheet. In addition, certain embedded features (the “embedded derivative”) included in the Series E Redeemable Preferred required bifurcation and are classified as derivative liabilities. The Warrants issued in conjunction with our redeemable preferred stocks are standalone instruments, indexed to our common stock, and do not include provisions requiring liability classification. As a result, these warrants are classified as equity.

The Series E and Series F Redeemable Preferred and Warrants were recorded at fair value upon issuance, net of issuance costs or discounts. The valuations are classified as Level 3. The Warrants were valued based on a Black-Scholes-Merton option pricing model and a Finnerty model to determine the estimated discount for lack of marketability resulting in an estimated fair value of $22.3 million. The Series E Redeemable Preferred was valued at an estimated fair value of $187.7 million (before issuance costs), with discounted cash flow models that calculates the present value of future cash flows using possible redemption scenarios and using published market yields for publicly traded unsecured fixed income securities with a similar credit ratings. No valuation input adjustments were considered necessary relating to the nonperformance risk for the Warrants or Series E Redeemable Preferred. Based on the terms of the Series F Redeemable Preferred, we determined that this share had minimal economic value.

For the embedded derivative, the derivative was valued at the date of issuance and at December 31, 2015, with changes in fair value recorded in our statement of operations. The embedded derivative was valued using the underlying number of shares as defined in the terms of the Series E Redeemable Preferred and included the market price of our common stock on the date of valuation. The valuation is classified as Level 2. At December 4, 2015 and December 31, 2015, the embedded derivative was valued at an estimated fair value of $2.8 million and $3.3 million, respectively. No valuation input adjustments were considered necessary relating to nonperformance risk for the embedded derivative.

The carrying value of the Series E Redeemable Preferred is being increased by periodic accretions (including the amount for dividends earned but not yet declared or paid) so that the carrying amount will equal the redemption value as of August 2, 2019, the earliest

51

possible redemption date by the holder. At December 31, 2015, the carrying value of these redeemable preferred stocks was $1 77.3 million. Approximately $3 million of accretion was recorded to retained earnings in 2015.

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.

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 ammonia, natural gas, copper, and steel, changes in market interest rates and changes in market currency exchange 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, 2015, we had no embedded losses associated with sales commitments with firm sales prices in our Chemical Business.

Commodity Price Risk

A substantial portion of our products and raw materials are commodities whose prices fluctuate as market supply and demand fundamentals change. We are exposed to commodity price risk as we generally do not use derivative financial instruments to manage risks related to changes in prices of commodities. Our Chemical Business periodically enters into contracts to purchase natural gas for anticipated production needs. Generally 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, these contracts are exempt from the accounting and reporting requirements relating to derivatives. At December 31, 2015, approximately 1,820,000 MMBtus’ of natural gas derivatives did not meet the definition of a normal purchase and sale and therefore a $0.10 change in natural gas price would impact income from continuing operations by approximately $0.2 million.

Interest Rate Risk

Generally, we are exposed to variable interest rate risk with respect to our revolving credit facility. As of December 31, 2015 we have zero borrowings on this credit facility. We are also exposed to interest rate risk on variable rate borrowings for certain commercial loans in the amount of approximately $31.0 million. We currently do not hedge our interest rate risk associated with these variable interest loans.

At December 31, 2015 and 2014, we did not have any financial instruments with fair values significantly different from their carrying amounts (which excludes issuance costs, if applicable), except for the 7.75% Senior Secured Notes as shown below.

|  | 2015 |  |  | 2014 |
|  | Carrying Amount |  |  | Estimated Fair Value |  |  | Carrying Amount |  |  | Estimated Fair Value |
|  | (In Thousands) |
7.75% Senior Secured Notes (1) |  | $ | 425 |  |  | $ | 355 |  |  | $ | 425 |  |  | $ | 442 |

(1) | Based on a quoted price of 83.65 at December 31, 2015 and 104 at December 31, 2014.

The 7.75% Senior Secured Notes valuation is classified as Level 2. In addition, the valuation of the 12% Senior Secured Notes is also classified as Level 2. 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 12% Senior Secured Notes are valued utilizing the current estimated market yield of our 7.75% Senior Secured Notes which have similar terms. The fair value measurements of our other 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 Exchange Act. Our disclosure controls and procedures are designed to provide reasonable assurance that the information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. These include controls and procedures designed to ensure that this information is accumulated and communicated to the Company’s management, including its Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure. 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, 2015 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

During the third quarter of 2014, we began implementing a new ERP system. We are implementing this system in discreet phases during the next few years. As a result, this implementation requires us to monitor and maintain appropriate internal control over financial reporting during this transition. It is possible that during each future phase of the implementation, we may make changes to our internal control over financial reporting that could materially affect our internal control over financial reporting. In addition, it is possible that during each phase of the implementation, we may make changes to our internal control over financial reporting that did not materially affect our internal control over financial reporting, but, when fully implemented, the cumulative effect of the changes made may be considered material.

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining effective internal control over financial reporting (as defined in Rule 13a-15(f) of the Exchange Act. Our internal control system is a process, under the supervision of the Company’s Chief Executive Officer and Chief Financial Officer, designed to provide reasonable assurance to our management and Board of Directors regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States. 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, with the participation of our Chief Executive Officer and Chief Financial Officer, assessed the effectiveness of our internal control over financial reporting as of December 31, 2015. 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 (2013 Framework). Based on our assessment, we believe that, as of December 31, 2015, 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, 2015 based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 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, 2015, 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, 2015 and 2014, and the related consolidated statements of operations, stockholders' equity, and cash flows for each of the three years in the period ended December 31, 2015 of LSB Industries, Inc. and our report dated February 29, 2016 expressed an unqualified opinion thereon.

Report of Independent Regist ered 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, 2015 and 2014, and the related consolidated statements of operations, stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2015. 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, 2015 and 2014, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 2015, 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, 2015, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 Framework) and our report dated February 29, 2016 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 water source and geothermal 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 were 20% to 50% owned and for which we had significant influence were accounted for on the equity method. All material intercompany accounts and transactions have been eliminated.

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.

Cash and Cash Equivalents – Investments, which consist of highly liquid investments with original maturities of three months or less, are considered cash equivalents.

Short-Term Investments - Investments, which consisted of certificates of deposit with an original maturity of 26 weeks, were considered short-term investments. These investments were carried at cost which approximated fair value.

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 to state them at net realizable value.

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.

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.

Notes to Consolidated Financial Statements (continued)

1. Summary of Significant Accounting Policies (continued)

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. During 2015, we incurred no natural gas property acquisition costs and $6.2 million of natural gas development costs.

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. 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. 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 total proved or proved developed reserves, as applicable, as estimated by our independent consulting petroleum engineer. 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. 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, 2015 and 2014, we had no long-lived assets classified as assets held for sale.

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. During 2015, our Chemical Business recognized non-cash impairment charges totaling $43.2 million including $39.7 million to write-down the carrying value of our working interest in natural gas properties in the Marcellus Shale region to their estimated fair value of $22.5 million and $3.5 million to write down the carrying value of certain plant assets related to certain ammonia production equipment at our Pryor Facility. These impairment charges represented the amount by which the carrying value of these long-lived assets exceeded the estimated fair values and were therefore not recoverable. For the natural gas properties, the estimated fair value was determined based on estimated future discounted net cash flows. The discounted cash flow method estimates future cash flows based on management’s estimates of future natural gas production, commodity prices based on commodity futures price strips, operating and development costs, and a risk-adjusted discount rate (10%). The fair value of proved natural gas properties is calculated using significant unobservable inputs (Level 3). The impairment was due to the decline in forward prices for natural gas, large natural gas price differentials in the Marcellus Shale region and changes in the drilling plans of these natural gas properties. For the ammonia production equipment, the estimated fair value was determined based on an offer received from a possible buyer less estimated costs that would be incurred if the equipment is sold (Level 3 inputs).

The non-cash impairment charges were included in the consolidated statements of operations line item titled impairment of long-lived assets.

Noncurrent Restricted Cash and Cash Equivalents - Noncurrent restricted cash and cash equivalents consisted of balances that were designated by us for specific purposes relating to capital projects.

Noncurrent Restricted Investments - Noncurrent restricted investments consisted of investment balances that were designated by us for specific purposes relating to capital projects.

Concentration of Credit Risks for Cash and Cash Equivalents – Financial instruments relating to cash and cash equivalents potentially subject us to concentrations of credit risk. All of these financial instruments were held by financial institutions within the U.S. and none of these financial instruments were in excess of the federally insured limits.

Capitalized Software – Intangible and other noncurrent assets includes capitalized software that primarily relate to implementing a new enterprise resource planning software (“ERP”) for internal use and is stated at cost, net of accumulated amortization. For 2015 and 2014 our carrying value was $ 19.9 million and $13.1 million, and accumulated amortization of $2.1 million and $0.5 million, respectively. Capitalized software costs include software purchase costs and internal and external costs for implementing software. For financial reporting purposes, amortization of capitalized software costs is computed using the straight-line method over the estimated useful lives of the software, which is primarily eight years. During 2015, 2014 and 2013, interest cost capitalized in capitalized software was $0.3 million, $0.5 million and $0.1 million, respectively. No provision for amortization is made until such time as the relevant assets are placed into service. Amortization expense related to capitalized software was $1.2 million and $0.4 million for 2015 and 2014, respectively and minimal in 2013. Estimated amortization related to capitalized software for each of the subsequent five years, 2016 through 2020, is $1.8 million, $2.6 million, $3.2 million, $3.2 million and $3.2 million, respectively. The estimated amortization is based on management’s expected ERP implementation completion by the end of 2017 to early 2018.

Capitalized Interest - Interest cost on borrowings incurred during a significant construction or development project is capitalized. Capitalized interest is added to the underlying asset and amortized over the estimated useful lives of the assets.

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 2015, 2014, or 2013. Goodwill relates to business acquisitions in prior periods in the following business segments:

|  | December 31, |
|  | 2015 |  |  | 2014 |
|  | (In Thousands) |
Chemical |  | $ | 1,621 |  |  | $ | 1,621 |
Climate Control |  |  | 103 |  |  |  | 103 |
Total goodwill |  | $ | 1,724 |  |  | $ | 1,724 |

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, 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.

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.

Redeemable Preferred Stocks - Our redeemable preferred stocks that are redeemable outside of our control are classified as temporary/mezzanine equity. The redeemable preferred stocks were recorded at fair value upon issuance, net of issuance costs or discounts. In addition, certain embedded features included in the Series E Redeemable Preferred required bifurcation and are classified as derivative liabilities. The carrying values of the redeemable preferred stocks are being increased by periodic accretions (including the amount for dividends earned but not yet declared or paid) so that the carrying amount will equal the redemption value as of August 2, 2019, the earliest possible redemption date by the holder. The amount of accretion was recorded to retained earnings.

1. Summary of Significant Accounting Policies (continued)

Warrants - The common stock warrants issued in conjunction with our redeemable preferred stocks are standalone instruments, indexed to our common stock, and do not include provisions requiring liability classification. As a result, these warrants are classified as equity. The warrants were recorded at fair value upon issuance, net of issuance costs or discounts. When such warrants are exercised, we may issue new shares of common stock and use treasury shares.

Equity Awards - 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, historically we issue new shares of common stock upon the exercise of stock options but treasury shares may be used.

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 extended 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.

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, loading and handling costs, warehousing costs, railcar lease costs and outbound freight. 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, professional fees, office and occupancy costs associated with the sales, marketing and administrative functions. SG&A also includes outbound freight in our Climate Control Business.

Shipping and Handling Costs – Shipping and handling costs not included in cost of sales for our Climate Control Business are as follows:

|  | 2015 |  |  | 2014 |  |  | 2013 |
|  | (In Thousands) |
Shipping and handling costs - SG&A |  | $ | 11,962 |  |  | $ | 10,146 |  |  | $ | 9,520 |

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.

|  | 2015 |  |  | 2014 |  |  | 2013 |
|  | (In Thousands) |
Advertising costs |  | $ | 2,295 |  |  | $ | 3,095 |  |  | $ | 3,157 |

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 fair value amounts recognized for our derivative contracts executed with the same counterparty under a master netting arrangement may be offset. We have the choice to offset or not, but that choice must be applied consistently. A master netting arrangement exists if the reporting entity has multiple contracts with a single counterparty that are subject to a contractual agreement that provides for the net settlement of all contracts through a single payment in a single currency in the event of default on or termination of any one contract. Offsetting the fair values recognized for the derivative contracts outstanding with a single counterparty results in the net fair value of the transactions being reported as an asset or a liability in the balance sheet. We have chosen to present the fair values of our derivative contracts under master netting agreements using a gross fair value presentation as there were no derivatives with fair values that were eligible to be offset as of December 31, 2015 and 2014.

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 (Loss) per Common Share - Net income (loss) attributable to common stockholders is computed by adjusting net income (loss) by the amount of dividends and dividend requirements on preferred stocks and the accretion of redeemable preferred stocks, if applicable. Basic loss per common share is computed by dividing net loss attributable to common stockholders by the weighted average number of common shares outstanding. For periods we earn net income, a proportional share of net income is allocated to participating securities, if applicable, determined by dividing total weighted average participating securities by the sum of the total weighted average common shares and participating securities (the “two-class method”). The Series E cumulative redeemable Class C preferred stock (the “Series E Redeemable Preferred”) issued in 2015 participate in dividends declared on our common stock and are therefore considered to be participating securities. Participating securities have the effect of diluting both basic and diluted income per common share during periods of net income. For periods we incur a net loss, no loss is allocated to participating securities because they have no contractual obligation to share in our losses. Diluted loss per common share is computed after giving consideration to the dilutive effect of our potential common stock instruments that are outstanding during the period, except where such non-participating securities would be anti-dilutive.

Recently Issued Accounting Pronouncements - In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2014-09, Revenue from Contracts with Customers (Topic 606), which will supersede nearly all existing revenue recognition guidance under GAAP. ASU 2014-19’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. We are evaluating our existing revenue recognition policies to determine whether any contracts in the scope of the guidance will be affected by the new requirements. The effects may include identifying performance obligations in existing arrangements, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. In July 2015, the FASB approved a one-year deferral of the effective date of this ASU with the option to early adopt but not before the original effective date. As a result, the effective date of this ASU for us is January 1, 2018, with the option to adopt a year earlier. This ASU allows for either “full retrospective” adoption, meaning the standard is applied to all of the periods presented, or “modified retrospective” adoption, meaning the standard is applied only to the most current period presented in the financial statements. We are currently evaluating the transition method that will be elected.

1. Summary of Significant Accounting Policies (continued)

In April 2015, the Financial Accounting Standards Board (“FASB”) issued ASU 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. In August 2015, the FASB also issued ASU 2015-15 Interest - Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements. ASU 2015-03 amends previous guidance to require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts or premiums. ASU 2015-15 allows an entity to defer and present debt issuance costs (related to line-of-credit arrangements) as an asset and subsequently amortize the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. The recognition and measurement guidance for debt issuance costs would not be affected by the amendments in these ASUs. Effective December 31, 2015, we early adopted these ASUs as allowed and applied the standards retrospectively as required, which resulted in the reclassification of approximately $6.4 million of debt issuance costs from other assets to long-term debt in our consolidated balance sheet as of December 31, 2014. Also see discussion included in Note 9 to Consolidated Financial Statements.

In July 2015, the FASB issued ASU No. 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory. The guidance requires an entity to measure inventory at the lower of cost or net realizable value, which is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation, rather than the lower of cost or market in the previous guidance. This amendment applies to inventory that is measured using first-in, first-out (FIFO). This amendment is effective for public entities for fiscal years beginning after December 15, 2016, including interim periods within those years. A reporting entity should apply the amendments prospectively with earlier application permitted as of the beginning of an interim or annual reporting period. We are currently evaluating the impact of this guidance, if any, on our consolidated financial statements and related disclosures.

In November 2015, the FASB issued ASU No. 2015-17, Balance Sheet Classification of Deferred Taxes (“ASU 2015-17”), which simplifies the presentation of deferred income taxes by eliminating the need for entities to separate deferred income tax liabilities and assets into current and noncurrent amounts in a classified statement of financial position. The guidance is effective for financial statements issued for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Earlier application is permitted for all entities as of the beginning of an interim or annual reporting period. The amendments in this ASU may be applied either prospectively to all deferred tax liabilities and assets or retrospectively to all periods presented. We currently do not expect a significant impact from adopting this ASU.

Correction of Immaterial Error and Reclassification – Based on a recent internal review of the classification of our costs and expenses in the fourth quarter of 2015, we concluded that certain shipping and handling costs associated with our Chemical Business were incorrectly classified in our consolidated statement of operations, with a portion of these costs classified as net sales and a portion of these costs classified as SG&A. As a result, we have retrospectively adjusted the amounts to reflect these costs within cost of sales, where a portion of shipping and handling costs historically had been presented. In accordance with ASU 250, Accounting Changes and Error Corrections, we evaluated the materiality of this change from quantitative and qualitative perspectives and concluded that the change in presentation was not material to any of our prior period financial statements and in particular, this change had no impact on operating income (loss) or income (loss) per share. In addition, the amount and classification of our shipping and handling costs included in net sales and SG&A have historically been disclosed. We revised our consolidated statement of operations for the years ended December 31, 2014 and 2013 to conform to the current presentation as summarized in the table below.

In addition, a reclassification has been made in our consolidated balance sheet at December 31, 2014 to conform to our consolidated balance sheet at December 31, 2015, as the result of the adoption of ASU 2015-03 and ASU 2015-15 as discussed above. The impact of this balance sheet reclassification is summarized in the table below.

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. Ten customers (including their affiliates), primarily relating to the Chemical Business, account for approximately 30% of our total net receivables at December 31, 2015.

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:

|  | 2015 |  |  | 2014 |  |  | 2013 |
|  | (In Thousands) |
Balance at beginning of year |  | $ | 8,817 |  |  | $ | 7,297 |  |  | $ | 6,172 |

Balance at end of year |  | $ | 10,551 |  |  | $ | 8,817 |  |  | $ | 7,297 |

8. Asset Retirement Obligations

Currently, we have various legal requirements related to operations 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 certain 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, 2015 and 2014, our accrued liability for AROs was $281,000 and $340,000, respectively.

(A) LSB and certain of its wholly-owned subsidiaries (the “Borrowers”) are parties to a senior secured revolving credit facility, as amended (the “Amended Working Capital Revolver Loan”). 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.

During 2015, the terms of this revolving credit facility were amended, pursuant to an amendment, dated as of June 11, 2015 (the “First Amendment”) and an amendment, dated as of November 9, 2015 (the “Second Amendment”). Pursuant to the First Amendment, the lender released its second-priority security interest and liens in collateral that also secures, on a first priority basis, the Senior Secured Notes discussed in (B) below. In addition, the First Amendment amends the revolving credit facility to more closely align the following provisions with the terms of the Senior Secured Notes discussed in (B) below:

| · | The definition of Permitted Investments is modified to (a) permit LSB to make investments to the extent that the Consolidated Leverage Ratio (as defined in the Amendment) does not exceed 2.50 to 1.00 over a trailing twelve month period from the measurement date; (b) permit investments in an amount not to exceed 50% of the consolidated net earnings of LSB and its subsidiaries since August 7, 2013, less consolidated net losses and other investments during the same period; and (c) permit $ 50 million in investments in Zena Energy, L.L.C.

| · | LSB is permitted to incur indebtedness without restriction if (i) the Fixed Charge Coverage Ratio (as defined by the Amended Working Capital Revolver Loan) is greater than 2.0 to 1.0, (ii) there is no default under the Amended Working Capital Revolver Loan and (iii) at least 20% of the maximum revolver commitment or $20 million, whichever is greater, is available.

The Second Amendment amends the revolving credit facility in the following respects, among other things:

| · | Expands the scope of and increases the basket of Permitted Purchase Money Indebtedness to the greater of (x) $35,000,000 and (y) 5.5% of the total consolidated assets of LSB and its subsidiaries as reflected on their consolidated balance sheet in accordance with GAAP, and permits the prepayment of Permitted Purchase Money Indebtedness;

| · | Excludes from the debt and lien covenants the financing of insurance premiums in the ordinary course of business, not in excess of the amount of such premiums; and

| · | Reduces the frequency of collateral reporting in the event that excess availability under the revolving credit facility falls below $30,000,000 from daily to weekly.

9. Long-Term Debt (continued)

In addition, the Amended Working Capital Revolver Loan and the Senior Secured Notes are cross collateralized as discussed in (B) below, other than with respect to the liens that the lender released in connection with the First Amendment, as discussed above. 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, 2015, the interest rate was 4.0% 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, 2015, the amount available for borrowing under the Amended Working Capital Revolver Loan was approximately $64.4 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:

| · | 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 assets.

The Amended Working Capital Revolver Loan allows the Borrowers and subsidiaries under the Senior Secured Notes to guarantee those notes. So long as (i) there is no default under the Amended Working Capital Revolver Loan and (ii) 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 and;

| · | certain investments, including, among others, 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.

9. Long-Term Debt (continued)

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 in a private transaction to qualified institutional buyers under Rule 144A and, outside of the United States, pursuant to Regulation S of the Securities Act of 1933 (as amended, the “Securities Act”) . In accordance with the registration rights agreement entered into at the time of the issuance of the 7.75% Senior Secured Notes, LSB and the guarantor subsidiaries completed an exchange offer to exchange the 7.75% Senior Secured Notes for substantially identical notes registered under the Securities Act. The registration statement for the exchange offer was declared effective by the SEC in May 2014, and the exchange offer was completed in June 2014. The 7.75% 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 on February 1st and August 1st.

On November 9, 2015, LSB sold $50 million aggregate principal amount of the 12% Senior Secured Notes due 2019 in a private placement exempt from registration under the Securities Act to certain private investors.

The 12% Senior Secured Notes bear interest at the annual rate of 12% and mature on August 1, 2019. Interest is to be paid semiannually on February 1st and August 1st, beginning February 1, 2016. The 12% Senior Secured Notes are secured on a pari passu basis with the same collateral securing the 7.75% Senior Secured Notes. The 12% Senior Secured Notes have covenants and events of default that are substantially similar to those applicable to the 7.75% Senior Secured Notes. The discussion below relates to both the 7.75% Senior Secured Notes and the 12% Senior Secured Notes (collectively, the “Senior Secured Notes”).

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 one, being senior secured guarantees and one being a senior unsecured guarantee. The Senior Secured Notes 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 above, and are 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 effectively be 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”).

F-23

LSB Industries, Inc.

Notes to Consolidated Financial Statements (continued)

9. Long-Term Debt (continued)

The Senior Secured Notes are secured on a first-priority basis by the Priority Collateral owned by LSB and the guarantors (other than the one unsecured guarantor) 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 one unsecured guarantor), 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 guarantor with respect to any obligations under any equally ranked lien obligations subsequently incurred. At December 31, 2015, the carrying value of the assets secured on a first-priority basis was approximately $1.0 billion and the carrying value of the assets secured on a second-priority basis was approximately $139.4 million.

The Senior Secured Notes are 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:

|  |  | 7.75% |  |  |  | 12% |
Year |  | Senior Secured Notes |  |  | Senior Secured Notes |
2016 |  |  | 103.875 | % |  |  | 106.000 | %
2017 |  |  | 101.938 | % |  |  | 103.000 | %
2018 and thereafter |  |  | 100.000 | % |  |  | 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.

9. Long-Term Debt (continued)

In connection with the 12% Senior Secured Notes, LSB entered into a registration rights agreement (the “Registration Rights Agreement-Notes”). Pursuant to the Registration Rights Agreement-Notes, we have agreed to use our reasonable best efforts to file with the SEC a 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 November 9, 2015 (the date of closing) and under certain other conditions, the annual interest rate on the notes will be increased by 0.25% (or approximately $350 per day) for the first 90 day period immediately following such default and 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 $1,400 per day).

In 2013, approximately $67.2 million of the proceeds from 7.75% Senior Secured Notes was used to pay all outstanding borrowings, including a prepayment premium, under a secured term loan facility. As a result of the payoff of the secured term loan facility, we incurred a loss on extinguishment of debt of $1.3 million in 2013, consisting of the prepayment premium and writing off unamortized debt issuance costs.

(C) See discussion under Secured Promissory Note Amendment in Note 22-Subsequent Events.

(D) On April 9, 2015, El Dorado Chemical Company (“EDC”), a subsidiary within our Chemical Business, entered into a secured promissory note due 2021 (the “Secured Promissory Note due 2021”) for an original principal amount of approximately $16.2 million. The Secured Promissory Note due 2021 bears interest at the rate of 5.25% per year and matures on March 26, 2021. Interest only is payable monthly for the first 12 months of the term. Principal and interest are payable monthly for the remaining term of the Secured Promissory Note due 2021. This Secured Promissory Note due 2021 is secured by a natural gas pipeline constructed at the El Dorado Facility and is guaranteed by LSB.

(E) On September 16, 2015, El Dorado Ammonia L.L.C. (“EDA”), a subsidiary within our Chemical Business, entered into a secured promissory note due 2022 (the “Secured Promissory Note due 2022”) for the construction financing of an ammonia storage tank and related systems with an initial funding received of $15 million and a maximum principal note amount of $19.8 million. The remainder of the funding under the Secured Promissory Note due 2022 is expected to be drawn upon completion of the ammonia storage tank, but in any event by May 2016 (the “Loan Conversion Date”). Up to the Loan Conversion Date, EDA will make monthly interest payments on the outstanding principal borrowed.

On the Loan Conversion Date, the outstanding principal balance will be converted to a seven year secured term loan requiring equal monthly principal and interest payments. In addition, a final balloon payment equal to the remaining outstanding principal (or 30% of the outstanding principal balance on the Loan Conversion Date) is required on the maturity date. The Secured Promissory Note due 2022 bears interest at a rate that is based on the monthly LIBOR rate plus 4.0% and matures in May 2022. The Secured Promissory Note due 2022 is secured by the ammonia tank and related systems and is guaranteed by LSB.

EDA may prepay all of the principal amount of the Secured Promissory Note due 2022 from the day following the first anniversary date of the Loan Conversion Date. A prepayment premium is required from the day following the first anniversary date of the Loan Conversion Date beginning at 1.114% and ending at 0.031%, a month prior to the maturity date.

10. Income Taxes

Provisions (benefit) for income taxes are as follows:

|  | 2015 |  |  | 2014 |  |  | 2013 |
|  | (In Thousands) |
Current: |  |  |  |  |  |  |  |  |  |  |  |
Federal |  | $ | (5,473 | ) |  | $ | (1,452 | ) |  | $ | (1,225 | )
State |  |  | 442 |  |  |  | 1,013 |  |  |  | 1,357 |
Total Current |  | $ | (5,031 | ) |  | $ | (439 | ) |  | $ | 132 |
Deferred: |  |  |  |  |  |  |  |  |  |  |  |
Federal |  | $ | (17,667 | ) |  | $ | 12,278 |  |  | $ | 32,197 |
State |  |  | (852 | ) |  |  | 561 |  |  |  | 3,092 |
Total Deferred |  | $ | (18,519 | ) |  | $ | 12,839 |  |  | $ | 35,289 |
Provisions (benefit) for income taxes |  | $ | (23,550 | ) |  | $ | 12,400 |  |  | $ | 35,421 |

The current benefit 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. For 2013 and 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 (benefit) 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, 2015, 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 $5.1 million. These credits carryforward for 20 years and begin expiring in 2034.

We utilized approximately $9.6 million, $5.9 million and $0.1 million of state NOL carryforwards to reduce tax liabilities in 2015, 2014 and 2013, respectively. At December 31, 2015, we have remaining federal and state tax NOL carryforwards of $47.7 million and $85.7 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 $27.8 million of alternative minimum tax (“AMT”) NOL carryforwards available as a deduction against future AMT income. The federal NOL carryforwards begin expiring in 2033 and the state NOL carryforwards began expiring in 2015.

We experienced a cumulative change in ownership of more than 50% over the three year testing period upon the issuance of the preferred stock and warrants on December 4, 2015. Pursuant to Internal Revenue Code Sections 382 and 383, annual use of the net operating losses and tax credits is subject to an estimated limitation of $3.7 million per year.

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 and in conjunction with the IRC Section 382 limitation and determined that it was more-likely-than-not that NOL’s and credits would be utilized before expiration. For 2015, 2014 and 2013, we determined it was more-likely-than-not that approximately $34.5 million, $8.1 million and $8.3 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 $1.2 million in 2015 and $0.3 million in 2014 and 2013.

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 $0.6 million in 2015 (none in 2014 and 2013), which is included in the net change in capital in excess of par value rather than an increase in the benefit 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, 2015 totaled $3.0 million and $2.9 million, respectively. At December 31, 2015 and 2014, we had $1.2 million and $1.1 million, respectively of unrecognized federal and state tax benefits resulting from the exercise of NSOs.

Deferred tax assets and liabilities include temporary differences and carryforwards as follows:

1 0. Income Taxes (continued)

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

|  | 2015 |  |  | 2014 |  |  | 2013 |
|  | (In Thousands) |
Provisions (benefit) for income taxes at federal statutory rate |  | $ | (20,391 | ) |  | $ | 11,263 |  |  | $ | 31,697 |
State current and deferred income taxes |  |  | (1,317 | ) |  |  | 1,497 |  |  |  | 3,916 |
Energy credit |  |  | (2,846 | ) |  |  | (110 | ) |  |  | (318 | )
Valuation allowance |  |  | 950 |  |  |  | — |  |  |  | — |

Provisions (benefit) for income taxes |  | $ | (23,550 | ) |  | $ | 12,400 |  |  | $ | 35,421 |

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

|  | 2015 |  |  | 2014 |  |  | 2013 |
|  | (In Thousands) |
Balance at beginning of year |  | $ | 657 |  |  | $ | 2,409 |  |  | $ | 2,292 |
Additions based on tax positions related to the current year |  |  | 70 |  |  |  | 45 |  |  |  | 97 |
Additions based on tax positions of prior years |  |  | 13 |  |  |  | 367 |  |  |  | 255 |
Reductions for tax positions of prior years |  |  | (443 | ) |  |  | (1,411 | ) |  |  | (123 | )
Settlements |  |  | (38 | ) |  |  | (753 | ) |  |  | (112 | )
Balance at end of year |  | $ | 259 |  |  | $ | 657 |  |  | $ | 2,409 |

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 financial condition. The total amount of unrecognized tax benefits that would impact the effective tax rate, if recognized, was $168,000, $160,000, and $204,000, net of federal expense, in 2015, 2014, and 2013, respectively.

We record interest related to unrecognized tax positions in interest expense and penalties in operating other expense. During 2014, we recognized a recovery of $518,000 in interest expense and penalties associated with the reduction of unrecognized tax positions (minimal in 2015). During 2013, we recognized $121,000 in interest and penalties associated with unrecognized tax benefits. At December 31, 2015 and 2014, the amounts accrued for interest and penalties were minimal.

LSB and certain of its subsidiaries file income tax returns in the U.S. federal jurisdiction and various state jurisdictions. With few exceptions, the 2012-2014 years remain open for all purposes of examination by the U.S. Internal Revenue Service (“IRS”) and other major tax jurisdictions. During 2014, we settled the examination with the IRS for the tax years 2008-2010 with no material changes to our financial position, results of operations and cash flow.

11. Commitments and Contingencies (continued)

Expenses associated with our operating lease agreements, including month-to-month leases, were $10,257,000 in 2015, $7,425,000 in 2014, and $6,401,000 in 2013. 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.

Covestro agreement - Subsidiaries within our Chemical Business, El Dorado Nitric Company and its subsidiaries (“EDN”) and EDC, are party to an agreement (the “Covestro Agreement”) with Covestro AG, formerly Bayer MaterialScience LLC (“Covestro”). EDN operates the nitric acid plant (the “Baytown Facility”) located within Covestro’s chemical manufacturing complex. Under the terms of the Covestro Agreement, Covestro purchases from EDN all of Covestro’s requirements for nitric acid for use in Covestro’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, Covestro has the right to terminate the Covestro Agreement upon payment of certain fees to EDN. The Covestro Agreement expires in June 2021, with options for renewal.

Ammonia supply agreement - On November 2, 2015, EDC and Koch Fertilizer, LLC (“Koch Fertilizer”) entered into an ammonia purchase and sale agreement under which Koch Fertilizer agrees to purchase, with minimum purchase requirements, the ammonia that (a) will be produced at the El Dorado Facility and (b) that is in excess of El Dorado’s needs. The initial term of the agreement is for three years, which term begins once the new ammonia plant is completed, and automatically continues for one or more additional one-year terms unless terminated by either party by delivering a notice of termination at least nine months prior to the end of term in effect. However, if the new ammonia plant is not in production by July 31, 2016, either party may provide notice of termination on or before October 31, 2016.

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).

Ammonia purchase agreement – EDC is party to an ammonia purchase agreement, as amended, with Koch Nitrogen International Sarl (“Koch”), under which Koch agrees to supply certain of the El Dorado Facility’s ammonia requirements. Under an amended agreement, the El Dorado Facility will purchase a majority of its ammonia requirement from Koch through the earlier of December 31, 2016 or the date on which the new ammonia plant comes on stream at the El Dorado Facility.

Natural gas gathering agreements – Zena owns an 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 each of the next five years and approximately $3.9 million thereafter for a total of approximately $12.9 million.

11. Commitments and Contingencies (continued)

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, 2015. During 2015, 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, 2015, our natural gas contracts, which are exempt from mark-to-market accounting, included the firm purchase commitments of approximately 5.1 million MMBtu of natural gas. These contracts extend through December 2016 at a weighted-average cost of $2.91 per MMBtu ($14.9 million) and a weighted-average market value of $2.47 per MMBtu ($12.7 million). In addition, we had standby letters of credit outstanding of approximately $2.8 million at December 31, 2015. We also had deposits from customers of $2.2 million for forward sales commitments, most of which relate to our Chemical Business at December 31, 2015.

Termination of Sales Commitment - Ammonium nitrate supply agreement—Pursuant to a long-term cost-plus supply agreement, EDC agreed to supply Orica International Pte Ltd (“Orica”) with an annual minimum of 240,000 tons of industrial grade ammonium nitrate (“AN”) produced at our El Dorado Facility. The agreement includes a provision for Orica to pay for product not taken. The agreement also includes a required notice of termination of one year, with the termination date to be no sooner than April 9, 2015. On March 31, 2014, EDC sent to Orica the required one-year notice that EDC would not renew the agreement. As a result, the agreement was terminated on April 9, 2015.

Wastewater Pipeline Operating Agreement – EDC is party to an operating agreement for the right to use a pipeline to dispose its wastewater. 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.

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, 2015, we have agreed to indemnify the sureties for payments, up to $17.3 million, made by them in respect of such bonds. All of these insurance bonds are expected to expire or be renewed in 2016.

Employment and Severance Agreements - We have employment 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 $8.9 million at December 31, 2015.

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 and to other laws regarding health and safety matters (collectively, the “Environmental and 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 and 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 and Health Laws and related enforcement policies 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. 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.

F-30

LSB Industries, Inc.

Notes to Consolidated Financial Statements (continued)

11. Commitments and Contingencies (continued)

Historically, significant expenditures have been incurred by subsidiaries within our Chemical Business in order to comply with the Environmental and Health Laws, and significant expenditures are 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 a working interest and compliance with Environmental 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, 2015, our accrued liabilities for environmental matters totaled $439,000 relating primarily to the 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 and overseen by the U.S.

Environmental Protection Agency (the “EPA”). These permits limit the type and amount of effluents that can be discharged and control the method of such discharge. The following are discharge water matters in relation to the respective state discharge water permits.

Our chemical facility located in Pryor, Oklahoma (the “Pryor Facility”) holds a permit to inject wastewater into an on-site well that is valid until 2018. The Oklahoma Department of Environmental Quality (“ODEQ”) has indicated that the permit may not be renewed and PCC may have to find an alternative means of disposal after the permit expires. PCC is continuing to discuss disposal possibilities both internally and with the ODEQ.

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. In 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 levels, but has, from time to time, had difficulty meeting the more restrictive dissolved minerals permit levels, primarily related to storm-water runoff. We do not believe this matter regarding meeting the permit requirements as to the dissolved minerals is a continuing issue for the process wastewater as the result of the El Dorado Facility disposing its wastewater (beginning in September 2013) via a pipeline constructed by the City of El Dorado, Arkansas. We believe that the issue with the storm-water runoff should be resolved if and when the ADEQ issues a new NPDES discharge water permit, which we have been advised that the ADEQ is currently processing.

During 2012, EDC paid a penalty of $100,000 to settle an administrative complaint issued by the EPA, and thereafter handled by the U.S. Department of Justice (“DOJ”), relating to certain alleged violations through 2010 of EDC’s 2004 NPDES discharge water permit. The DOJ advised that action would also be taken for alleged violations occurring after 2010. As of the date of this report, no action has been filed by the DOJ against EDC. As a result, the cost (or range of costs) cannot currently be reasonably estimated regarding this matter. Therefore, no liability has been established at December 31, 2015.

In addition, the El Dorado Facility is currently operating under a consent administrative order (the “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 risk assessment was submitted in August 2007. In February 2015, the ADEQ stated that El Dorado Chemical was meeting the requirements of the CAO and should continue semi-annual monitoring. 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, 2015, in connection with this matter.

2. Air Matters

One of our subsidiaries within our Chemical Business, PCC has been advised that the ODEQ is conducting an investigation into whether the chemical production facility located in Pryor, Oklahoma is in compliance with certain rules and regulations of the ODEQ and whether PCC’s reports of certain air emissions primarily in 2011 were intentionally reported incorrectly to the ODEQ. PCC has cooperated with the ODEQ in connection with this investigation. As of December 31, 2015, we are not aware of any recommendations made or to be made by the ODEQ with respect to legal action to be taken or recommended as a result of this ongoing investigation.

3. Other Environmental Matters

During 2013, the EPA conducted a risk management inspection of our Cherokee Facility. During 2014, our Cherokee Facility received a notice of violation from the EPA as a result of the inspection, which listed eleven alleged violations. Our Cherokee Facility has provided the EPA with written responses. During May 2015, our Cherokee Facility received a settlement letter from the EPA, which terms have been accepted by the Cherokee Facility, and we are awaiting the final consent decree from the EPA. Under the proposed settlement agreement, we agreed to pay a penalty in the form of providing approximately $100,000 to purchase emergency response equipment for the local first responders plus a civil penalty to the EPA of approximately $26,000. A final consent decree to settle this matter was issued and signed by CNC in December 2015. The consent decree will become final upon signing by the EPA and filing with the court. As a result, we have accrued for the amount of this settlement, which is included in our accrued liabilities for environmental matters discussed above.

In 2002, two subsidiaries within our Chemical Business sold substantially all of their operating assets relating to a Kansas chemical facility (the “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 develop 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.

As the successor to a prior owner of the Hallowell Facility, Chevron Environmental Management Company (“Chevron”) has agreed in writing, within certain limitations, to pay and has been paying one-half of the costs of the investigation and interim measures relating to this matter as approved by the Kansas Department of Health and Environment (the “KDHE”), subject to reallocation.

Our subsidiary and Chevron are pursuing with the state of Kansas, including the KDHE, a corrective action strategy relating to the Hallowell Facility. This strategy currently includes long-term surface and groundwater monitoring to track the natural decline in contamination. During 2014, the KDHE approved a corrective action study work plan and will consider and recommend restoration or replacement pursuant to the work plan and/or whether to seek compensation in its evaluation. Currently, it is unknown what remediation and damages the KDHE may require, if any, but it is reasonably possible that certain remediation activities could be required to begin in 2016. The ultimate required remediation, if any, is currently unknown. Our subsidiary and Chevron have retained an environmental consultant to perform the corrective action study work plan as to the appropriate method to remediate the Hallowell Facility. The resulting study was submitted to the KDHE for review. We are advised by our consultant that until the study is completed there is not sufficient information to develop a meaningful and reliable estimate (or range of estimate) as to the cost of the remediation. We accrued our allocable portion of costs primarily 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. As more information becomes available our estimated accrual will be refined.

B. Other Pending, Threatened or Settled Litigation

In 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 was a customer of EDC, purchasing AN from EDC from time to time. LSB and EDC received letters from counsel purporting to represent subrogated insurance carriers, personal injury claimants and persons who suffered property damages informing LSB and EDC 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. Initial lawsuits filed named West Fertilizer and another supplier of AN as defendants. In 2014, EDC and LSB were named as defendants, together with other AN manufacturers and brokers that arranged the transport and delivery of AN to West Fertilizer, in the case styled City of West, Texas v CF Industries, Inc., et al, in the District Court of McLennan County, Texas. The plaintiffs allege, among other things, that LSB and EDC were negligent in the production and marketing of fertilizer products sold to West Fertilizer, resulting in death, personal injury and property damage. EDC 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 placed its liability insurance carrier on notice, which carrier is handling the defense for LSB and EDC concerning this matter. Our product liability insurance policies have aggregate limits of general liability totaling $100 million, with a self-insured retention of $250,000. In August 2015, the trial court dismissed plaintiff’s negligence claims against us and EDC based on a duty to inspect, but allowed the plaintiffs to proceed on claims for design defect and failure to warn. Subsequently, we and EDC have entered into entered into a confidential settlement agreements with several plaintiffs that had claimed wrongful death and bodily injury. A portion of this settlement was paid by the insurer during 2015 and in January 2016. While these settlements resolve the claims of what we believe were the highest risk cases in this matter for us, we continue to be party to litigation related to this explosion by other plaintiffs, in addition to indemnification or defense obligations we may have to other defendants. We intend to continue to defend these lawsuits vigorously and we are unable to estimate a possible range of loss at this time if there is an adverse outcome in this matter as to EDC. As of December 31, 2015, no liability reserve has been established in connection with this matter, except for the unpaid portion of the settlement agreement discussed above, but we have incurred professional fees up to our self-insured retention amount.

In May of 2015, our subsidiary, EDC, was sued in the matter styled BAE Systems Ordinance Systems, Inc. (“BAE”), et al. vs. El Dorado Chemical Company, in the United States District Court, Western District of Arkansas, for an alleged breach of a supply agreement to provide BAE certain products. It is EDC’s position, among other things, that its inability to deliver to BAE was due to a force majeure event caused by a fire and explosion at EDC’s nitric acid plant, and that a force majeure clause in the supply agreement therefore excuses EDC’s performance under the supply agreement. BAE’s pre-litigation demand indicated a claim of approximately $18 million. EDC intends to vigorously defend this matter. The cost (or range of costs), if any, EDC would incur relating to this matter cannot currently be reasonably estimated. Therefore, no liability has been established at December 31, 2015.

In September 2015, a case styled Dennis Wilson vs. LSB Industries, Inc., et al., was filed in the United States District Court for the Southern District of New York. The plaintiff purports to represent a class of our shareholders and asserts that we violated federal securities laws by allegedly making material misstatements and omissions about delays and cost overruns at our El Dorado Chemical Company manufacturing facility and about our financial well-being and prospects. The lawsuit, which also names certain current and former officers, seeks an unspecified amount of damages. Given the uncertainty of litigation, the preliminary stage of the case, and the legal standards that must be met for, among other things, class certification and success on the merits, we cannot estimate the reasonably possible loss or range of loss that may result from this action.

11. Commitments and Contingencies (continued)

In September 2015, we and El Dorado Ammonia L.L.C (“EDA”) received formal written notice from Global Industrial, Inc. (“Global”) of Global’s intention to assert mechanic liens for labor, service, or materials furnished under certain subcontract agreements for the improvement of the new ammonia plant at our El Dorado Facility. Global is a subcontractor of Leidos Constructors, LLC (“Leidos”), the general contractor for EDA for the construction for the ammonia plant. Leidos terminated the services of Global with respect to their work performed at our El Dorado Facility in July 2015 and Global claims it is entitled to payment for certain work prior to its termination in the sum of approximately $18 million. Leidos reports that it made an estimated $6 million payment to Global on or about September 11, 2015, and EDA paid Leidos approximately $3.5 million relating to work performed by subcontractors of Global. Leidos has not approved certain payments to Global pending the result of on-going audits and investigation undertaken to quantify the financial impact of Global’s work. EDA intends to monitor the Leidos audit, and conduct its own investigation, in an effort to determine whether any additional payment should be released to Global for any work not in dispute. LSB and EDA intend to pursue recovery of any damage or loss caused by Global’s work performed at our El Dorado Facility. In January 2016, El Dorado, Leidos and Global reached an agreement whereby the approximately $3.6 million claims of Leidos’ remaining unpaid subcontracts, vendors and suppliers will be paid (and these suppliers and subcontractors will in turn issue releases of their respective claims and liens. In addition, Global will reduce the value of its claim as against Leidos, and its lien amount as against the Project by a like amount. After all such lower tier supplier and subcontractors are satisfied, the Global claim and lien amount will be reduced to approximately $5 million. No liability has been established in connection with the remaining $5.0 million claim. In addition, LSB and EDA intend to pursue recovery of any damage or loss caused by Global’s work performed at our El Dorado Facility.

We are also involved in various other claims and legal actions including claims for damages resulting from water leaks related to our Climate Control Business products and other product liability occurrences. Most of the product liability claims are covered by our general liability insurance, which includes a deductible of $250,000 or $500,000 per claim, depending on the policy period. For any claims or legal actions that we have assessed the likelihood of our liability as probable, we have recognized our estimated liability. At December 31, 2015, our accrued general liability insurance claims were $621,000 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 Covestro. 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 Covestro 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. In addition, certain embedded features (“embedded derivative”) included in the Series E Redeemable Preferred required bifurcation and are discussed Note 13. 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.

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, 2015 and 2014, the valuations of contracts classified as Level 2 related to certain futures/forward natural gas contracts, a foreign exchange contract, an interest rate swap contract and an embedded derivative. For the natural gas contracts, these contracts are valued using the prices pursuant to the terms of the contracts and using market information for futures/forward natural gas prices. At December 31, 2015, the valuation inputs included the contractual weighted-average cost of $2.35 per MMBtu and the estimated weighted-average market value of $2.35 per MMBtu.

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

For foreign exchange contracts, these contracts are valued using the foreign currency exchange rates pursuant to the terms of the contract and using market information for foreign currency exchange rates. The valuation inputs included the total contractual exchange rate of 1.12 and the total estimated market exchange rate of 1.09 (U.S. Dollar/Euro). 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, 2015, the valuation inputs included the contractual weighted-average pay rate of 3.23% and the estimated market weighted-average receive rate of 0.61%. For the embedded derivative, the derivative is valued using the underlying number of shares as defined in the terms of the Series E Redeemable Preferred and the market price of our common stock. At December 31, 2015, the valuation inputs included the market price of our common stock, which was $7.25 per share. No valuation input adjustments were considered necessary relating to nonperformance risk for the contracts as discussed above.

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, 2015 and 2014, the valuations ($2.35 and $2.50 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 most recent sales transaction and reevaluated for market changes, if any, and on the range of ask/bid prices obtained from a broker adjusted for minimal market volume activity, respectively. 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 or the associated contractual obligations.

Commodities Contracts

Raw materials for use in our manufacturing processes include copper used by our Climate Control Business and natural gas and platinum 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, 2015, we did not have any futures/forward copper contracts. At December 31, 2014, our futures/forward copper contracts included 1,750,000 pounds of copper, extended through May 2015 at a weighted-average cost of $2.98 per pound. At December 31, 2015, our futures/forward natural gas contracts included 1,820,000 MMBtu of natural gas, extend through December 2016 (includes contractual costs indexed to future NYMEX prices) at a weighted-average cost of $2.35 per MMBtu. At December 31, 2014, our futures/forward natural gas contracts (accounted for on a mark-to-market basis) included approximately 8,279,000 MMBtu of natural gas, extend through June 2016 at a weighted-average cost of $3.24 per MMBtu. At December 31, 2015, we did not have any futures/forward platinum contracts. At December 31, 2014, our futures/forward platinum contracts included 3,000 ounces of platinum, extended through April 2015 at a weighted-average cost of $1,224.26 per ounce. 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. At December 31, 2015, our foreign exchange contract was for the receipt of approximately 280,000 Euros through February 2017 at the contractual exchange rate of 1.12 (U.S. Dollar/Euro. At December 31, 2014, our foreign exchange contract was for the receipt of approximately 819,000 Euros through May 2015 at the contractual exchange rate of 1.27 (U.S. Dollar/Euro. These contracts are free-standing derivatives and are accounted for on a mark-to-market basis. 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 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, 2015, 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 Covestro, 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 Covestro and EDN. We have no obligation to reimburse Covestro 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, 2015 and 2014, we had approximately 495,000 and 1,112,000 carbon credits, respectively, 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.

Embedded Derivative

As discussed in Note 13, the Series E Redeemable Preferred included the embedded derivative that required bifurcation. At December 31, 2015 the fair value of the embedded derivative was based on the equivalent of 456,225 shares of our commons stock at $7.25 per share.

The following details our assets and liabilities that are measured at fair value on a recurring basis at December 31, 2015 and 2014:

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

None of our assets or liabilities measured at fair value on a recurring basis transferred between Level 1 and Level 2 classifications for the periods presented below except for certain futures/forward natural gas contracts (an asset with an estimated fair value of $31,000 at December 31, 2013) that were transferred from Level 1 to Level 2 since a portion of these contracts were expected to be settled on dates that quoted prices were not available. As a result, we are utilizing observable market data other than quoted prices to value these contracts. The classification transfer of the contracts was deemed to occur in the first quarter of 2014. In addition, the following is a reconciliation of the beginning and ending balances for assets and liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3):

The Senior Secured Notes valuations are classified as Level 2. In addition, the valuation of the 12% Senior Secured Notes is also classified as Level 2. 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 12% Senior Secured Notes are valued utilizing the current estimated yield of our 7.75% Senior Secured Notes which have similar terms. The fair value measurements of our other 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. Securities Financing Including Redeemable Preferred Stocks

Securities Purchase Agreement Including Redeemable Preferred Stocks

On December 4, 2015, LSB entered into a securities purchase agreement (the “Securities Purchase Agreement”) with, LSB Funding LLC, a Delaware limited liability company (the “Purchaser”), and Security Benefit Corporation, a Kansas corporation (the “Purchaser Guarantor”) both of which are unrelated third parties, pursuant to which LSB agreed to sell to the Purchaser, in a private placement (the “Private Placement”) exempt from registration under the Securities Act,

| · | $210,000,000 of the Series E Redeemable Preferred,

| · | warrants to purchase 4,103,746 shares of common stock, par value $0.10, which is equal to 17.99% of the outstanding shares of our common stock before the completion of the Private Placement (the “Warrants”), and

| · | one share of Series F redeemable Class C preferred stock (the “Series F Redeemable Preferred,” and together with the Series E Redeemable Preferred and the Warrants, the “Securities”). The Private Placement closed on December 4, 2015 (the “Closing Date”).

In connection with the closing of the Private Placement (the “Closing”), LSB entered into

| · | the Certificate of Designations setting forth the rights, preferences, privileges and restrictions applicable to the Series E Redeemable Preferred, as filed with the Secretary of State of the State of Delaware (the “Series E COD”);

| · | the Certificate of Designations setting forth the rights, preferences, privileges and restrictions applicable to the Series F Redeemable Preferred, as filed with the Secretary of State of the State of Delaware (the “Series F COD”);

| · | a Registration Rights Agreement by and between LSB and LSB Funding (the “Registration Rights Agreement Notes”); and

| · | an Amendment to Renewed Rights Agreement, (the “Rights Agreement Amendment”), which amended the Renewed Rights Agreement by and between LSB and UMB Bank, n.a., as rights agent (“UMB”), dated as of December 4, 2008 (the “Renewed Rights Agreement”)

The Series E and Series F Redeemable Preferred and Warrants were recorded at fair value upon issuance, net of issuance costs or discounts. The valuations are classified as (Level 3). The Warrants were valued based on a Black-Scholes-Merton option pricing model and a Finnerty model to determine the estimated discount for lack of marketability resulting in an estimated fair of $22.3 million. The Series E Redeemable Preferred was valued at an estimated fair value of $187.7 million, with discounted cash flow models that calculates the present value of future cash flows using possible redemption scenarios and using published market yields for publicly traded unsecured fixed income securities with a similar credit ratings. No valuation input adjustments were considered necessary relating to the nonperformance risk for the Warrants or Series E Redeemable Preferred. Based on the terms of the Series F Redeemable Preferred, we determined that this share had minimal economic value. See additional discussion below under Series E Redeemable Preferred relating to the bifurcation of certain embedded derivatives.

13. Securities Financing Including Redeemable Preferred Stocks (continued)

Series E Redeemable Preferred

The Series E COD authorizes 210,000 shares of Series E Redeemable Preferred. With respect to the distribution of assets upon liquidation, dissolution or winding up of LSB, whether voluntary or involuntary, the Series E Redeemable Preferred ranks (i) senior to the common stock, the Series B 12% Cumulative Convertible Preferred Stock, the Series D 6% Cumulative Convertible Class C Preferred Stock, the Series 4 Junior Participating Class C Preferred Stock and any other class or series of stock of LSB (other than Series E Redeemable Preferred) that ranks junior to the Series E Redeemable Preferred either or both as to the payment of dividends and/or as to the distribution of assets on any liquidation, dissolution or winding up of the Corporation (the “Junior Stock”); (ii) on a parity with the other shares of Series E Redeemable Preferred and any other class or series of stock of LSB (other than Series E Redeemable Preferred) created after the date of the Series E COD (that specifically ranks pari passu to the Series E Redeemable Preferred) and (iii) junior to any other class or series of stock of LSB created after the date of the Series E COD that specifically ranks senior to the Series E Redeemable Preferred.

The Series E Redeemable Preferred has a 14% annual dividend rate and a participating right in dividends and liquidating distributions equal to 456,225 shares of common stock, which is equal to 2% of LSB’s outstanding common stock before the transaction was completed. Generally, the holders of the Series E Redeemable Preferred Shares (the “Series E Holders”) will not have any voting rights or powers, and consent of the Series E Holders will not be required for taking of any action by LSB. However, the Series E Holders’ consent is required for

| · | amendments to increase or decrease the authorized amount of Series E Redeemable Preferred,

| · | the creation or increase of any shares of any class or series of capital stock of LSB ranking pari passu with or senior to the Series E Redeemable Preferred, or

| · | any amendment that adversely affect the powers, preferences or special rights of the Series E Redeemable Preferred.

Dividends accrue semi-annually in arrears and are compounded. Dividends are payable only when and if declared by the Board of Directors (the “Board”).

Additionally, LSB must declare a dividend on the Series E Redeemable Preferred on a pro rata basis with the common stock. As long as LSB Funding holds at least 10% of the Series E Redeemable Preferred, LSB may only declare dividends on Junior Stock unless and until dividends have been declared and paid on the Series E Redeemable Preferred for the then current dividend period in cash. The Series E Redeemable Preferred has a liquidation preference per share of $1,000 plus accrued and unpaid dividends plus the participation rights value (the “Liquidation Preference”). The participation rights value is the product of the pro rata number of Series E Redeemable Preferred shares being redeemed and the price of our common stock as of such date.

At any time on or after August 2, 2019, each Series E Holder has the right to elect to have such holder’s shares redeemed by LSB at a redemption price per share equal to the Liquidation Preference of such share as of the redemption date. Additionally, LSB, at its option, may redeem the Series E Redeemable Preferred at any time at a redemption price per share equal to the Liquidation Preference of such share as of the redemption date. Lastly, with receipt of (i) prior consent of the electing Series E holder or a majority of shares of Series E Redeemable Preferred and (ii) all other required approvals, including under any principal U.S. securities exchange on which our common stock is then listed for trading, LSB can redeem the Series E Redeemable Preferred by the issuance of shares of common stock having an aggregate common stock price equal to the amount of the aggregate Liquidation Preference of such shares being redeemed in shares of common stock in lieu of cash at the redemption date.

In the event of liquidation, the Series E Redeemable Preferred is entitled to receive its Liquidation Preference before any such distribution of assets or proceeds is made to or set aside for the holders of our common stock and any other Junior Stock. In the event of a change of control, the Company must make an offer to purchase all of the shares of Series E Redeemable Preferred outstanding.

The Series E Redeemable Preferred is redeemable outside of our control and is therefore classified as temporary/mezzanine equity. As a result of an analysis performed on the embedded derivatives within the Series E Redeemable Preferred, the redemption features were determined to not be clearly and closely related to the debt-like host and also did not meet any other scope exceptions for derivative accounting. Therefore these redemption features are being accounted for as derivative instruments and the fair value of these derivative instruments were bifurcated from the Series E Redeemable Preferred and recorded as a liability. See discussion in Note 12.

Series F Redeemable Preferred

The Series F COD authorizes one (1) shares of Series F Redeemable Preferred. The Series F Redeemable Preferred has voting rights (the “Series F Voting Rights”) to vote as a single class on all matters which the common stock have the right to vote and is entitled to a number of votes equal to 4,559,971 shares of our common stock, which is equal to 19.99% of the number of outstanding shares of our common stock before the completion of the Private Placement; provided however, the number of votes that may be cast by the Series F Redeemable Preferred will be reduced automatically upon the occurrence of the following specified events:

| · | upon any exercise of the Warrants, the Series F Voting Rights shall be reduced by a number of votes equal to the number of shares of our common stock into which the Warrants are exercised,

| · | upon the redemption or exchange of each share of Series E for our common stock, the Series F Voting Rights shall be reduced by a number of shares of common stock equal to the amount specified in clauses (i) and (ii) of Participation Rights Value as specified in the Series E COD, and

| · | upon (A) expiration of the exercise period set forth in the Warrants or exercise in full of the Warrants and (B) redemption or exchange in full of all shares of Series E Redeemable Preferred for our common stock, cash or otherwise, the Series F Voting Rights shall be reduced to zero.

With respect to the distribution of assets upon liquidation, dissolution or winding up of LSB, whether voluntary or involuntary, the Series F Redeemable Preferred ranks (i) senior to our common stock and (ii) ranks junior to LSB’s Series B 12% Cumulative Convertible Preferred Stock, Series D 6% Cumulative Convertible Class C Preferred Stock, Series 4 Junior Participating Class C Preferred Stock, Series E Redeemable Preferred and any other class or series of stock of LSB after the date of the Series F COD that specifically ranks senior to the Series F Redeemable Preferred.

The Series F Redeemable Preferred will be automatically redeemed by LSB, in whole and not in part, for $0.01 immediately following the date upon which the Series F Voting Rights have been reduced to zero.

In the event of liquidation, the Series F Redeemable Preferred is entitled to receive its liquidation preference of $100 before any such distribution of assets or proceeds is made to or set aside for the holders of our common stock and any other stock junior to the Series F Redeemable Preferred.

Warrants

In connection with the Closing, LSB issued a Warrant to purchase our common stock (the “Warrant Agreement”) to LSB Funding to purchase 4,103,746 shares of common stock. Each warrant affords the holder the opportunity to purchase one share of common stock at a warrant exercise price of $0.10. The Warrants expire on December 4, 2025.

The number of shares of our common stock for which a Warrant is exercisable, and the exercise price per share of such Warrant are subject to adjustment from time to time pursuant to Section 2 of the Warrant Agreement upon the occurrence of certain events, including the subdivision or combination of common stock or the issuance of a dividend to all holders of our common stock.

13. Securities Financing Including Redeemable Preferred Stocks (continued)

Upon the occurrence of certain events constituting a Fundamental Transaction (as defined therein) as a result of which the common stock would be converted into, changed into or exchanged for, stock, securities or other assets (including cash or any combination thereof), each holder of a Warrant will have the right to receive, upon exercise of a Warrant, an amount of securities, stock, securities or other assets received in connection with such event with respect to or in exchange for the number of shares of our common stock for which such Warrant is exercisable immediately prior to such event.

Registration Rights Agreement- Warrants

On December 4, 2015 (the date of closing), LSB entered into a registration rights agreement (the “Registration Rights Agreement-Warrants”) relating to the registered resale of the common stock issuable upon exercise of the Warrants and certain other common stock. Pursuant to the Registration Rights Agreement-Warrants, we are required to file a registration statement for such registered resale within nine months from the date of closing, to permit the public resale of registrable securities then outstanding from time to time as permitted by Rule 415 under the Securities Act. We are required to use commercially reasonable efforts to cause the registration statement to become effective as soon as practicable thereafter.

Furthermore, the registration statement must be declared effective within twelve months after the date of closing by filing a post-effective amendment. If the exchange offer is not completed on or prior to the expiration of twelve months from the date of closing, LSB Funding is entitled to liquidated damages of 0.25% of the liquidated damages multiplier (the closing price of LSB’s common stock as of the date of the calculation multiplied by the number of LSB’s common stock issued upon the exercise of the Warrants, and other issuance events if applicable, and held by LSB Funding that may not be disposed of without restriction and without the need for current public pursuant to Rule 144 under the Securities Act) for the first 30 day period immediately following such default and an additional 0.25% with respect to each subsequent 30 day period, up to a maximum increase of 1.00%. In no event will the aggregate of all liquidated damages exceed 3.0% of the aggregate purchase price (the closing price of LSB’s common stock as of the date of the calculation multiplied by the number of LSB’s common stock issued upon the exercise of the Warrants, and other issuance events if applicable).

If such liquidated damages cannot be paid in cash, because such action would constitute a default under a credit facility or other debt instrument, then payment consisting of as much cash as possible in compliance with the aforementioned conditions would be required. The balance of any compensatory liquidated damages would be paid in full in the form of the issuance of additional common stock.

In certain circumstances, the warrants’ purchaser(s) may have piggyback registration rights and rights to request an underwritten offering. Such parties will cease to have registration rights on the later of the tenth anniversary of the closing date or the date on which the registrable securities cease to be registrable securities.

Amendment to Renewed Rights Agreement

Pursuant to the Securities Purchase Agreement, on December 4, 2015, LSB and UMB Bank, as rights agent, entered into an amendment to the renewed rights agreement as discussed under “Preferred Share Rights Plan” in Note 14 – Stockholders Equity.

14. Stockholders’ Equity

2008 Stock Incentive Plan - During 2014, our stockholders approved an amendment to our Incentive Stock Plan (the “2008 Plan”). As amended, the total number of shares of our common stock for which awards may be granted under the 2008 Plan is 1,975,000 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.

Our Board 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, the 2008 Plan expires on June 5, 2018.

14. Stockholders’ Equity (continued)

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 Director Stock Option Plan - In addition to the 2008 Plan discussed above, we have an Outside Director 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 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.

Stock Incentive Plans - At December 31, 2015, we have options outstanding under the 2008 Plan as discussed above. As it relates to stock options, exercise price of the outstanding options granted under the 2008 Plan was equal to the market value of our common stock at the date of grant.

The following information relates to our stock option plans:

|  | December 31, 2015 |
|  | 2008 Plan |  |  | Outside Director Plan |
Maximum number of securities for issuance |  |  | 1,975,000 |  |  |  | 400,000 |
Number of awards available to be granted |  |  | 797,890 |  |  |  | 278,456 |
Number of options outstanding |  |  | 802,780 |  |  |  | — |
Number of options exercisable |  |  | 232,925 |  |  |  | — |

In addition to our stock option plans, in 2006 our stockholders approved the grant of 450,000 shares of stock options (the “2006 Options”) to certain Climate Control Business employees. The exercise price of the 2006 Options is $8.01 per share. At December 31, 2015, there were 40,000 options outstanding related to the 2006 Options, of which 20,000 are exercisable.

Restricted Stock - On December 31, 2015 the Committee approved the grants under the 2008 Plan of 584,959 shares of restricted stock (“2015 Restricted Stock”) to certain executives, of which a portion of these awards immediately vested as of the grant date. The non-vested 2015 Restricted Stock carry dividend and voting rights. Sales of these shares are restricted prior to the date of vesting. Excluding the shares that immediately vested, the 2015 Restricted Stock vest at the end of each one-year period at the rate of one-third per year for three years. The fair value of the 2015 Restricted Stock was $4,200,000, or $7.18 per share, which was the market value of our common stock at the date of grant. Pursuant to the terms of the 2015 Restricted Stock agreements, unvested restricted shares will immediately vest upon the occurrence of a change in control (as defined by agreement), termination without cause or death. In 2015, stock-based compensation expense (SG&A) related to restricted stock was $405,000 (not applicable for 2014 and 2013), which was also the fair value of the restricted stock that vested. The total income tax benefit related to these grants was approximately $156,000.

Stock-Options - During 2015, the Committee approved the grants under the 2008 Plan of 135,000 shares of stock options (the “2015 Options”) to certain employees. During 2014, the Committee approved the grants under the 2008 Plan of 489,000 shares of stock options (the “2014 Options”) to certain employees. The exercise price of the 2015 Options and the 2014 Options was equal to the market value of our common stock at the date of grant. The 2015 Options and 2014 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. The 2015 Options and the 2014 Options expire in 2025 and 2024, respectively. The fair value for the 2015 Options and the 2014 Options was estimated, using an option pricing model, as of the date of the grant, which date was also the service inception date. During 2013, the Committee did not grant any awards under the 2008 Plan.

The fair value for the 2015 Options and the 2014 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:

|  | 2015 |  |  | 2014 |  |  | 2013 |

Preferred Share Rights Plan - On January 5, 2009, a renewed shareholder rights plan (the “Renewed Rights Agreement”) became effective upon the expiration of our previous shareholder rights plan. Pursuant to the Securities Purchase Agreement as discussed in Note 13 - Securities Financing, on December 4, 2015, LSB and UMB, as rights agent, entered into an amendment (the “Amendment”) to the Renewed Rights Agreement. The Amendment amends the definition of “Acquiring Person” to exclude the Purchaser and its Affiliates and Associates (as defined therein) in order to permit the issuance of the Securities discussed in Note 13, and additional securities issuable to the Purchaser as contemplated by the terms of the Securities, without triggering the issuance of Series 4 Junior Participating Class C Preferred Stock. The Renewed Rights Agreement will impact a potential acquirer unless the acquirer negotiates with our Board and the Board 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 Holders and certain other limited excluded persons, as amended), 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 may exchange each Right (other than those held by the acquirer) for one share of our common stock, subject to adjustment. Our Board 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 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.

Other – As of December 31, 2015, we have reserved 6.4 million shares of common stock issuable upon potential conversion of preferred stocks, equity awards and warrants pursuant to their respective terms.

15. Non-Redeemable Preferred Stock

Series Non-Redeemable B Preferred - The 20,000 shares of Series B 12% cumulative, convertible preferred stock (“Series B Preferred”), $100 par value, are convertible, in whole or in part, into 666,666 shares of our common stock (33.3333 shares of common stock for each share of preferred stock) at any time at the option of the holder and entitle the holder to one vote per share. The Series B Preferred provides for annual cumulative dividends of 12% from date of issue, payable when and as declared. All of the outstanding shares of the Series B Preferred are owned by the Golsen Holders.

Series Non-Redeemable D Preferred - The 1,000,000 shares of Series D 6% cumulative, convertible Class C preferred stock (“Series D Preferred”) have no par value and are convertible, in whole or in part, into 250,000 shares of our common stock (1 share of common stock for 4 shares of preferred stock) at any time at the option of the holder. Dividends on the Series D Preferred are cumulative and payable annually in arrears at the rate of 6% per annum of the liquidation preference of $1.00 per share. Each holder of the Series D Preferred shall be entitled to .875 votes per share. All of the outstanding shares of Series D Preferred are owned by the Golsen Holders.

Cash Dividends Paid – During 2015, 2014 and 2013, we paid the following annual cash dividends on our non-redeemable preferred stock in each of the respective year:

| · | $240,000 on the Series B Preferred ($12.00 per share) and

| · | $60,000 on the Series D Preferred ($0.06 per share).

At December 31, 2015, the amount of accumulated dividends on the Series B and Series D Preferred totaled approximately $78,000.

Other - At December 31, 2015, we are authorized to issue an additional 230,000 shares of $100 par value preferred stock and an additional 3,790,000 shares of no par value preferred stock. Upon issuance, our Board will determine the specific terms and conditions of such preferred stock.

16. Executive Benefit Agreements and Employee Savings Plans

We are party to individual benefit agreements (“1992 Agreements”) with certain key current and former executives, death benefit agreements (“1981 Agreements”) with certain key executives, and a death benefit agreement (“2005 Agreement”) with our Executive Chairman. 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 Executive Chairman’s death, we will pay to our Executive Chairman’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 Executive Chairman’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 Executive Chairman and the Company.

(1) | During 2015, the employment of certain executives, subject to the provisions of the 1981 and 1992 Agreements, were terminated, resulting in the forfeiture of the respective benefits. As a result of these events, the accrual for these estimated benefits was derecognized resulting in a net recovery of costs associated with executive benefits.

Accrued death and executive benefits under the above agreements are included in current and noncurrent accrued and other liabilities. We accrue for such liabilities when they become probable and discount the liabilities to their present value.

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. A reportable segment may include several business units that offer similar products and services. The reportable segments are managed separately from each other because they manufacture and distribute distinct products with different production processes.

We evaluate performance and allocate resources based on operating results. 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:

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

| · | high purity and commercial grade 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 the last several years, our Chemical Business encountered a number of significant issues including the events discussed in Note 20 – Property and Business Interruption Insurance Claims and Recoveries and numerous mechanical issues at the Pryor Facility, all resulting in lost production and causing an adverse effect on our sales and operating income for the periods presented. Also see footnotes (2) and (3) below and Note 20 regarding business interruption and property insurance recoveries.

Other products relate to working interests in certain natural gas properties. In 2012 and 2013, a subsidiary within our Chemical Business acquired these working interests. Since our Chemical Business purchases a significant amount of natural gas as a feedstock for the production of 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). For 2015, we incurred a net loss of $42.8 million from our working interests in natural gas properties. This net loss consisted of $3.4 million in net sales less $6.3 million of cost of sales (DD&A of $5.2 million and production costs of $1.1 million), $0.2 million of SG&A and a non-cash impairment charge of $39.7 million.

As of December 31, 2015, our Chemical Business employed 576 persons, 197 of whom are 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:

| · | water source and geothermal heat pumps,

| · | hydronic fan coils, and

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

Notes to Consolidated Financial Statements (continued)

18. Segment Information (continued)

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, Oklahoma 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.

Other - The business operation classified as “Other” primarily sells industrial machinery and related components to machine tool dealers and end users located primarily in North America.

21. 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.

In October 2013, we settled these claims with our insurance carriers for the aggregate amount of $113 million. 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.

LSB Industries, Inc.

Notes to Consolidated Financial Statements (continued)

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

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.

In 2013, we received business interruption insurance recovery of $15 million and 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. 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.

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 in 2013 and $28.5 million paid to us in 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 was recognized as income associated with this settlement in 2014.

22. Subsequent Events

Secured Promissory Note Amendment - 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 followed 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 maturity date was amended on January 5, 2016 from February 1, 2016 to April 1, 2016.

Principal and interest are payable in two monthly installments totaling approximately $1.3 million with interest based on the LIBOR rate plus 300 basis points with a final balloon payment of $14.0 million due at maturity. The interest rate at December 31, 2015 was 3.42%. The loan is secured by the Working Interests and related properties and proceeds.

Secured Promissory Note due 2019 - On February 5, 2016, El Dorado Chemical Company, a subsidiary within our Chemical Business, entered into a secured promissory note due 2019 for an original principal amount of $10.0 million. The secured promissory note due 2019 bears interest at the rate of 5.73% per annum and matures on June 29, 2019. Principal and interest are payable in 40 equal monthly installments with a final balloon payment of approximately $6.7 million. The Secured Promissory Note due 2019 is secured by the cogeneration facility equipment and is guaranteed by LSB. Our agreement allows us to secure up to an additional $10 million in financing on the cogeneration facility equipment.

Supplemental Natur al Gas Disclosures

During 2015 we did not have any exploratory wells or related costs.

The following unaudited information regarding our gas reserves has been prepared and is presented pursuant to requirements of the Securities and Exchange Commission (SEC) and the Financial Accounting Standards Board (FASB).

Our Chemical Business owns working interests in certain natural gas properties, all of which are located in Wyoming County, Pennsylvania, within the Marcellus Shale. 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. Our Chemical Business purchases a significant amount of natural gas as a feedstock for the production of ammonia. Management considers this acquisition as an economic hedge against a potential rise in natural gas prices in the future for a portion of our future natural gas production requirements.

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 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.

Our 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.

During September 2015, our Chemical Business recognized an impairment charge of $39.7 million to write-down the carrying value of our working interest in natural gas properties in the Marcellus Shale region to their estimated fair value of $22.5 million. The impairment charge represented the amount by which the carrying value of these natural gas properties exceeded the estimated fair value and was therefore deemed impaired. The estimated fair value was determined based on estimated future discounted net cash flows, a Level 3 input, using estimated production and prices at which we reasonably expect natural gas will be sold, including information provided by our independent consulting petroleum engineer. The impairment was due to the decline in forward prices for natural gas, large natural gas price differentials in the Marcellus Shale region and changes in the drilling plans of these natural gas properties.

The independent consulting petroleum engineering firm of Pinnacle Energy Services of Oklahoma City, Oklahoma calculated the Company’s natural gas reserves as of December 31, 2015 using volumetric analysis of the reservoir and rate decline analysis for existing producers. (See exhibit 23.2 and exhibit 99.1 included in this report). The process of estimating proved reserves and future net cash flows is complex involving decisions and assumptions in evaluating the available engineering and geologic data and prices natural gas and the cost to produce these reserves and other factors, many of which are beyond our control. As a result, these estimates are imprecise and should be expected to change as future information becomes available. These changes could be significant. In addition, this information should not be construed as being the current fair market value of our proved reserves.

As a non-operator of our natural gas properties, we rely on information provided from the operator which is given to our independent consulting petroleum engineering firm for use in the preparation of our reserve estimates. The reserve estimates are reviewed by our Chemical accounting group for accuracy and checked for consistency in its preparation along with validating the assumptions provided by the operator based on actual performance. Additionally, members of management, meet with the operator quarterly to review our properties and discuss performance.

Estimated Quantities of Proved Natural Gas Reserves

Estimated quantities of proved natural gas reserves are summarized as follows:

|  | Proved |  |  | Proved |

Production |  |  | (3,742 | ) |  |  | — |
Year-end 2015 |  |  | 24,807 |  |  |  | 8,096 |

The revisions of previous estimates for proved undeveloped reserves is primarily attributable to 25,812 MMcf of reserves which are no longer projected to be developed within five years from the date they were added to the proved undeveloped reserves due to low commodity prices and a delayed timing of the development plan put in place by the operator. There were no transfers of PUD reserves to proved developed during 2015. There are only four locations that remain in the PUD category at the end of 2015 and we anticipate that all of these locations will be drilled and converted to PDP within five years from the date they were added based on the operator’s current development plan.

We do not have any estimated reserves of crude oil, synthetic oil, synthetic gas or products of other non-renewable natural resources that are intended to be upgraded into synthetic oil and synthetic gas.

In 2015 reserve additions from new wells drilled and completed during the year are shown accounted for using the successful efforts method for our share of working interest wells applying industry practices for new well classifications. There were 4 new well additions in 2015.

Estimates of future cash flows from proved natural gas reserves are shown in the following table. Estimated income taxes are calculated by applying the appropriate tax rates to the estimated future pre-tax net cash flows less depreciation of the tax basis of properties and the statutory depletion allowance.

Future net cash flows were computed using prices used in estimating proved natural gas reserves, year-end costs, and statutory tax rates (adjusted for tax deductions) that relate to proved natural gas reserves.

Changes in the standardized measure of discounted future net cash flow follows:

Net change in income taxes |  |  | 14,207 |
Other |  |  | 3,818 |
Aggregate change for the year |  | $ | (42,113 | )

Our working interests and the associated net revenue interests are contractually defined and based on a percentage of production at prevailing market prices. We receive our percentage of production in cash. Similarly, our working interests and the associated net revenue interests are contractually defined and we pay our proportionate share of the capital and operating costs for the development and operation of the well. Our revenues fluctuate based on changes in the market prices for natural gas, the decline in production from existing wells, and other factors affecting natural gas exploration and production activities, including the cost of development and production.

Our average sales price of gas produced during the year was $1.01 per Mcf and our average production costs were $0.23 per Mcf. Our gross productive natural gas wells as of December 31, 2015 were 34 and our net productive gas wells when applying our working interests were 4.08. We do not operate any wells and there were no wells in process of drilling at December 31, 2015.
