NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Note 1: Summary of Significant Accounting Policies

For a complete discussion of our significant accounting policies, refer to the notes to our audited consolidated financial statements included in our Form 10-K for the year ended December 31, 2014 (“2014 Form 10-K”), filed with the Securities and Exchange Commission (“SEC”) on February 27, 2015.

Basis of Consolidation and Presentation - LSB Industries, Inc. (“LSB”) and its subsidiaries (the “Company”, “We”, “Us”, or “Our”) are consolidated in the accompanying condensed 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 are 20% to 50% owned and for which we have significant influence are accounted for on the equity method. All material intercompany accounts and transactions have been eliminated.

In the opinion of management, the unaudited condensed consolidated financial statements of the Company as of March 31, 2015 and for the three-month periods ended March 31, 2015 and 2014 include all adjustments and accruals, consisting of normal, recurring accrual adjustments which are necessary for a fair presentation of the results for the interim periods. These interim results are not necessarily indicative of results for a full year due, in part, to the seasonality of our sales of agricultural products and the timing of performing our major plant maintenance activities. Our 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.

Certain information and footnote disclosures normally included in financial statements prepared in accordance with United States (“U.S.”) generally accepted accounting principles (“GAAP”) have been condensed or omitted in this Form 10-Q pursuant to the rules and regulations of the SEC. These condensed consolidated financial statements should be read in connection with our audited consolidated financial statements and notes thereto included in our 2014 Form 10-K.

Use of Estimates - The preparation of condensed consolidated financial statements in conformity with 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 consist of certificates of deposit with an original maturity no more than 26 weeks, are considered short-term investments. These investments are carried at cost which approximates fair value.

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 consist of investment balances that are designated by us for specific purposes relating to capital projects. The balance includes investments in certificates of deposits with an original maturity no longer than approximately 26 weeks. The investments in certificates of deposits are carried at cost, which approximates fair value.

Concentration of Credit Risks for Cash, Cash Equivalents, and Investments at Financial Institutions – Financial instruments relating to cash, cash equivalents, and investments (certificates of deposits) potentially subject us to concentrations of credit risk. At March 31, 2015, the total balance of these financial instruments exceeded the FDIC-insured limits by approximately $49.0 million. All of these financial instruments were held by financial institutions within the U.S.

Note 1: Summary of Significant Accounting Policies (continued)

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

Recently Issued Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board issued Accounting Standard Update 2014-09-Revenue from Contracts with Customers, which will supersede nearly all existing revenue recognition guidance under GAAP. The standard’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. The original effective date for us of this standard is January 1, 2017. However, the FASB has proposed a one-year deferral of the effective date to January 1, 2018 with the option to early adopt using the original effective date. The standard 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.

One of our subsidiaries, El Dorado Chemical Company is party to an agreement with Bank of America, N.A. to sell our accounts receivables generated from product sales to a certain customer. We agreed to enter into this agreement as a courtesy to this customer. The term of this agreement matures in August 2015, with renewal options, but either party has an option to terminate the agreement pursuant to the terms of the agreement. In addition, we amended our sales agreement with the customer to offer extended payment terms under the condition that they pay an extended payment terms premium equal to the discount taken by the Bank when the accounts receivables are sold. Thus, there is no gain or loss from the sale of these receivables to the Bank. We have no continuing involvement or risks associated with the transferred accounts receivable. Pursuant to the terms of the agreement, EDC is to receive payment from the Bank no later than one business day after the Bank’s acceptance of EDC’s offer to sell the accounts receivables. As of March 31, 2015, EDC has been paid by the Bank for the accounts receivables sold to the Bank. We account for these transfers as sales under ASC 860 – Transfers and Servicing.

Note 4: Inventories

At March 31, 2015 and December 31, 2014, inventory reserves for certain slow-moving inventory items (Climate Control products) were $1,775,000 and $1,653,000, respectively. In addition, because cost exceeded the net realizable value, inventory adjustments for certain nitrogen-based inventories provided by our Chemical Business were $221,000 and $1,976,000 at March 31, 2015 and December 31, 2014, respectively.

Note 6: 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:

	Three Months Ended March 31,
	2015			2014
	(In Thousands)
Balance at beginning of period	$	8,817		$	7,297

Balance at end of period	$	9,034		$	7,578

Note 7: Asset Retirement Obligations

Currently, we have various legal requirements related to operations of 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 asset retirement obligations. In addition, we currently have no plans to discontinue the use of these facilities, and the remaining life of the facilities is indeterminable. As a result, a liability for only a minimal amount relating to AROs associated with these facilities has been established. However, we will continue to review these obligations and record a liability when a reasonable estimate of the fair value can be made. In addition, our Chemical Business owns working interests in certain natural gas properties. We recognized AROs associated with the obligation to plug and abandon wells when the natural gas reserves in the wells are depleted. At March 31, 2015 and December 31, 2014, our accrued liability for AROs was $368,000 and $340,000, respectively.

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 with an annual minimum of 240,000 tons of industrial grade AN produced at our El Dorado Facility. The agreement included a provision for Orica to pay for product not taken. The agreement also included 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.

Planned Capital Additions – A subsidiary of EDC is party to various agreements with Leidos Constructors, LLC and others to engineer, procure and construct an ammonia plant and certain support facilities. The estimated cost for this project ranges from $275 million to $300 million, of which $172 million has been incurred and capitalized at March 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. In particular, the manufacture, production and distribution of products by our Chemical Business are activities that entail environmental and public health risks and impose obligations under the Environmental Laws and the Health Laws, many of which provide for certain performance obligations, substantial fines and criminal sanctions for violations. There can be no assurance that we will not incur material costs or liabilities in complying with such laws or in paying fines or penalties for violation of such laws. The Environmental Laws and Health Laws and enforcement policies thereunder have in the past resulted, and could in the future result, in significant compliance expenses, cleanup costs (for our sites or third-party sites where our wastes were disposed of), penalties or other liabilities relating to the handling, manufacture, use, emission, discharge or disposal of hazardous or toxic materials at or from our facilities or the use or disposal of certain of its chemical products. Historically, significant expenditures have been incurred by subsidiaries within our Chemical Business in order to comply with the Environmental Laws and Health Laws and are reasonably expected to be incurred in the future. We will also be obligated to manage certain discharge water outlets and monitor groundwater contaminants at our Chemical Business facilities should we discontinue the operations of a facility. We do not operate the natural gas wells where we own a working interest and compliance with Environmental Laws and Health Laws is controlled by others, with our Chemical Business being responsible for its proportionate share of the costs involved. As of March 31, 2015, our accrued liabilities for environmental matters totaled $514,000 relating primarily to matters discussed below. It is reasonably possible that a change in the estimate of our liability could occur in the near term. Also see discussion in Note 7 - Asset Retirement Obligations.

1. Discharge Water Matters

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

The El Dorado Facility is subject to a state National Pollutant Discharge Elimination System discharge water permit issued by the Arkansas Department of Environmental Quality. 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 limits, but has, from time to time, had difficulty demonstrating consistent compliance with the more restrictive dissolved minerals permit levels We do not believe this matter regarding meeting the permit requirements as to the dissolved minerals is a continuing issue 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.

During 2012, EDC paid a penalty of $100,000 to settle an Administrative Complaint issued by the EPA, and thereafter handled by the United States Department of Justice, relating to certain alleged violations of EDC’s 2004 NPDES permit for alleged violations through 2010. The DOJ advised that some action would 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 March 31, 2015.

In addition, the El Dorado Facility is currently operating under a consent administrative order 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. 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 March 31, 2015, in connection with this matter.

2. Air Matters

One of our subsidiaries, PCC, within our Chemical Business, has been advised that the Oklahoma Department of Environmental Quality is conducting an investigation into whether the chemical production facility located in Pryor, Oklahoma was in compliance with certain rules and regulations of the ODEQ and whether PCC’s reports of certain air emissions relating primarily to 2011 were intentionally reported incorrectly to the ODEQ. PCC has cooperated with the ODEQ in connection with this investigation. As of March 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 May 2014, the EPA conducted a Risk Management inspection of our Cherokee Facility. During October 2014, our Cherokee Facility received a notice of violation from the EPA as a result of the inspection listing eleven alleged violations. Our Cherokee Facility has had numerous conference calls and provided the EPA with written responses. During a March 2015 conference call with the EPA, the EPA provided our Cherokee Facility with some preliminary penalties as a result of the alleged violations. We anticipate receiving a formal notice of violation during 2015 from the EPA, which notice will state the amount of the penalty that the EPA will assert against the Cherokee Facility. As a result, we have accrued an estimated amount for penalties of approximately $112,000, 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 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.

The successor of a prior owner of the Hallowell Facility 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 Environmental Quality, subject to reallocation.

Our subsidiary and Chevron are pursuing with the state of Kansas, including the Kansas Department of Health and Environmental, a corrective action strategy relating to the Hallowell Facility. This strategy currently includes a long-term surface and groundwater monitoring to track the natural decline in contamination. During December 2014, the KDHE approved a corrective action study work plan, and the KDHE is to consider and recommend restoration or replacement pursuant to the work plan and/or whether to seek compensation. The KDHE will consider the recommendations in its evaluation. Currently, it is unknown what remediation and damages the KDHE would require, if any, but we believe that certain remediation activities will be required to begin during 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, which study is not scheduled to be completed until the end of 2015. We have been advised by our consultant that until the study has been completed there are too many unknowns to have a meaningful and reliable estimate as to the cost of the remediation. We have accrued for 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 relating to the study during 2015, our estimated accrual will be refined.

B. Other Pending, Threatened or Settled Litigation

In 2013, an explosion and fire occurred at the West Fertilizer Co. located in West, Texas, causing death, bodily injury and substantial property damage. West Fertilizer is not owned or controlled by us, but West Fertilizer had been a customer of EDC, purchasing AN from EDC from time to time. LSB and EDC previously received letters from counsel purporting to represent subrogated insurance carriers, personal injury claimants and persons who suffered property damages informing them that their clients are conducting investigations into the cause of the explosion and fire to determine, among other things, whether AN manufactured by EDC and supplied to West Fertilizer was stored at West Fertilizer at the time of the explosion and, if so, whether such AN may have been one of the contributing factors of the explosion. Other manufacturers of AN also supplied AN to West Fertilizer. Initially, the lawsuits that had been filed named West Fertilizer and another supplier of AN as defendants. There have been certain responses to discovery in connection with the pending lawsuits that possibly some of the AN products at West Fertilizer at the time of the explosion may have been produced by EDC. 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. Plaintiffs are alleging, 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 has retained a firm specializing in cause and origin investigations, with particular experience with fertilizer facilities, to assist EDC in its own investigation. LSB and EDC have placed its liability insurance carrier on notice, 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. Our legal counsel in this matter has represented to us that while it is extremely early in this litigation, they believe our chances of ultimately confirming the merits of EDC’s legal position are probable. However, if there is an adverse outcome in this matter as to EDC, we are unable to estimate a possible range of loss at this time. As of March 31, 2015, no liability has been established in connection with this matter, but we have incurred professional fees up to our self-insured retention amount.

We are also involved in various other claims and legal actions including claims for damages resulting from water leaks related to our Climate Control products and other product liability occurrences. Most of the product liability claims are covered by our general liability insurance, which generally includes a deductible of $250,000 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 up to the applicable deductible. At March 31, 2015, our accrued general liability insurance claims were $576,000 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.

Note 10: Derivatives, Hedges, Financial Instruments and Carbon Credits

Periodically, we have three classes of contracts that are accounted for on a fair value basis, which are commodities futures/forward contracts (“commodities contracts”), foreign exchange contracts and interest rate contracts as discussed below. All of these contracts are used as economic hedges for risk management purposes but are not designated as hedging instruments. In addition as discussed below, we are issued climate reserve tonnes (“carbon credits”), of which a certain portion of the carbon credits are to be sold and the proceeds given to Bayer. The assets for carbon credits are accounted for on a fair value basis as discussed below. Also, the contractual obligations to give the related proceeds to Bayer are accounted for on a fair value basis (as discussed below) unless we enter into a firm sales commitment to sell the carbon credits. 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 March 31, 2015, the valuations of contracts classified as Level 2 related to certain futures/forward natural gas contracts, a foreign exchange contract and an interest rate swap contract.

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 March 31, 2015, the valuation inputs included the contractual weighted-average cost of $3.09 per MMBtu and the estimated weighted-average market value of $2.73 per MMBtu.

Note 10: 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 1.27 and the total estimated market exchange rate of 1.07 (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 March 31, 2015, the valuation inputs included the contractual weighted-average pay rate of 3.23% and the estimated market weighted-average receive rate of 0.44%. 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 March 31, 2015 and December 31, 2014, the valuations ($2.50 per carbon credit, for both periods) 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 and 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 March 31, 2015, our futures/forward copper contracts include 1,950,000 pounds of copper and extend through December 2015 at a weighted-average cost of $2.96 per pound. At December 31, 2014, our futures/forward copper contracts include 1,750,000 pounds of copper, extend through May 2015 at a weighted-average cost of $2.98 per pound. At March 31, 2015, our futures/forward natural gas contracts (accounted for on a mark-to-market basis) include approximately 6,406,000 MMBtu of natural gas and extend through June 2016 (includes contractual costs indexed to future NYMEX prices) at a weighted-average cost of $3.09 per MMBtu. At December 31, 2014, our futures/forward natural gas contracts include 8,279,000 MMBtu of natural gas and extend through June 2016 at a weighted-average cost of $3.24 per MMBtu. At March 31, 2015, our futures/forward platinum contracts include 3,000 ounces of platinum and extend through July 2015 at a weighted-average cost of $1,120.87 per ounce. At December 31, 2014, our futures/forward platinum contracts include 3,000 ounces of platinum and extend 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 March 31, 2015, our foreign exchange contract was for the receipt of approximately 648,000 Euros through May 2015 at the contractual exchange rate of 1.27 (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 the three months ended March 31, 2015 and 2014, 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 performed at the Baytown Facility. Pursuant to the terms of the agreement with Bayer, a certain portion of the carbon credits are to be used to recover the costs of the Project, and any balance thereafter to be allocated between Bayer and EDN. We have no obligation to reimburse Bayer for their costs associated with the Project, except through the transfer or sale of the carbon credits when such credits are issued to us. The assets for carbon credits are accounted for on a fair value basis and the contractual obligations associated with these carbon credits are also accounted for on a fair value basis (unless we enter into a sales commitment to sell the carbon credits). At March 31, 2015 and December 31, 2014, we had approximately 1,086,000 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.

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

At March 31, 2015 and December 31, 2014, we did not have any financial instruments with fair values significantly different from their carrying amounts, except for the Senior Secured Notes. At March 31, 2015 and December 31, 2014, the estimated fair value of the Senior Secured Notes exceeded the carrying value by approximately $17 million based on a quoted price of 104.0. These valuations are 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 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.

Note 15: Subsequent Event

On April 30, 2015, a class action lawsuit was filed against our subsidiary, ClimateMaster, Inc. (“CM”), in the case styled Emmert, et al. v. ClimateMaster, Inc., in the United States District Court, Western District of Oklahoma. CM is a subsidiary within our Climate Control Business. The lawsuit alleges that a manufacturing defect in the air conditioning and heat pump equipment manufactured by CM has caused failures in certain valves used in such equipment resulting in damages sustained by consumers and the contractors, and further alleges that CM sold the equipment despite knowing of these defects. The plaintiffs are alleging that there are more than 100 class members and that the aggregate amount in controversy exceeds $5 million, exclusive of interest and costs. Plaintiffs seek actual and punitive damages, together with recovery of certain expenses. Because we have just been notified of this lawsuit, we have not had an opportunity to investigate the claims contained therein, but intend to vigorously defend this matter. We are also investigating whether such claims come within our insurance coverage, and, as of the date hereof, have not determined if the claims alleged in the lawsuit are covered under our insurance policy.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following Management’s Discussion and Analysis of Financial Condition and Results of Operations should be read in conjunction with a review of the other Items included in this Form 10-Q including our March 31, 2015 condensed consolidated financial statements included elsewhere in this report. Certain statements contained in this MD&A may be deemed to be forward-looking statements. See “Special Note Regarding Forward-Looking Statements.”

Overview

General

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

• Chemical Business manufactures and sells nitrogen-based chemical products 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.

Items Affecting Comparability of Results

Chemical Business

Property and Business Interruption Insurance Claims and Recoveries

In January 2014, we settled a claim with our insurance carriers for the aggregate amount of approximately $43.5 million related to business interruption and property damage at our Cherokee Facility. In the first quarter of 2014, we recognized the remaining $28.0 million of this claim, of which approximately $22.9 million was recognized as a reduction to cost of sales and $5.1 million was recognized as property insurance recoveries in excess of losses incurred.

Debt and Interest Expense

During August 2013, in connection with a major expansion of our El Dorado Facility, LSB sold $425 million of 7.75% Senior Secured Notes. During the first quarter of 2014 and 2015, interest expense was $6.7 million and $3.4 million, respectively net of capitalized interest of $2.3 million and $5.6 million, respectively. Interest was capitalized based upon construction in progress of the El Dorado expansion and certain other capital projects.

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, among other factors, world grain demand and production levels, the cost and availability of transportation, storage, weather conditions, competitive pricing and the availability of imports. An expansion or upgrade of competitors’ facilities, international 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.

24

As reported in Green Markets and based upon the January USDA release of its 2014 Crop Production Summary and the WASDE Report dated April 9, 2015, for the 2014/2015 corn season, production is estimated at 14.2 billion bushels or 351 million metric tons, 3% above the prior season. Additionally, the average U. S. yield for the 2014/2015 corn season was an estimated record of 171.0 bushels per acre compared to 158.1 bushels per acre in the prior season. WASDE also estimated the ending U.S. corn stocks to be 46.4 million metric tons compared to 31.3 million metric tons at the same time last season for the same period. Due to the expectation of the abundant supply, corn prices are low relative to pricing over the last three years; most recently reported at $3.81 per bushel. 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 and demand which likely will drive ammonia, UAN and urea prices. Current WASDE estimates are for 88-89 million acres of corn to be planted in 2015 compared to approximately 91 million planted in 2014. However with fewer acres, farmers will expect better yields requiring increased nitrogen fertilizers. Notwithstanding the current conditions, the fundamentals continue to be positive for nitrogen fertilizer products we produce and sell and gross margins still continue to be favorable, with the current exception of AN produced at the El Dorado Facility from purchased ammonia, which is one of the reasons for the current construction project of an ammonia plant at our El Dorado Facility. Additionally, while unfavorable weather conditions were experienced during the quarter, mainly excessive rain and cooler temperatures that has delayed nitrogen applications, the demand for nitrogen during the second quarter should be strong.

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. Our sales prices generally vary with the market price of our feedstock (ammonia, natural gas or sulfur, as applicable) in our pricing arrangements with customers.

Mining

Our mining products are industrial grade AN and AN solutions. The primary uses are as ammonium nitrate fuel oil, specialty emulsions primarily in surface mining of coal and for usage in quarries and the construction industry. As reported by the U.S. Energy Information Administration, annual coal production for 2014 was up 1% over 2013. EIA is forecasting a 7% decline in coal production for 2015, before growing 2% in 2016 with the Appalachia region expected to drive the decline in coal production with expected declines of approximately 13% in 2015. For 2015, the Powder River Basin and the Illinois Basin regions are estimated to decline 6% and 2%, respectively. We believe that coal production in the U.S. will face significant challenges assuming that natural gas prices remain at current levels and given that export demand could be lower due to the current strong 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 industrial grade AN.

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. Over the last five years, U.S. natural gas reserves have increased significantly due to, among other factors, advances in extracting shale gas, which have reduced and stabilized natural gas prices, providing North America with a cost advantage over certain imports. As a result, we believe that 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. We historically 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 fluctuations, which has have an impact on our cost of producing nitrogen fertilizer. The following table shows the first quarter volume of natural gas we purchased and the average cost per MMBtu:

25

	2015		2014
Natural gas volumes (MMBtu in millions)		3.3		2.5
Natural gas average cost per MMBtu	$	3.32	$	4.61

Beginning in December 2014, Henry Hub natural gas prices have trended below $4.00 averaging approximately $2.90 in the first quarter of 2015.

Ammonia Prices

Ammonia is the primary feedstock for the production of agricultural and industrial grade AN at our El Dorado Facility. Ammonia pricing is based on a published Tampa, Florida market index. The Tampa index is commonly used in annual contracts for both the agricultural and 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. Additionally, the El Dorado Facility’s cost to produce agricultural grade AN from purchased ammonia can periodically exceed our selling price (a cost disadvantage as compared to producing ammonia from natural gas) as discussed below. Subject to availability, the El Dorado Facility has the ability to source a portion of its ammonia requirements from our Pryor Facility, which cost is significantly lower than current market prices. Once our new ammonia production plant at the El Dorado Facility commences production (expected to begin in the first quarter of 2016), we believe this cost disadvantage will be eliminated. Over the past several years, ammonia prices have experienced large fluctuations. The table below shows the El Dorado Facility’s first quarter volume of ammonia purchased and the average cost per short ton:

	2015		2014
Ammonia volumes (tons in thousands)		38		40
Ammonia average cost per short ton	$	488	$	419

Based upon full plant production, the El Dorado Facility would normally purchase 200,000 to 220,000 tons per year of ammonia feedstock. In the first quarters of 2015 and 2014, the purchased ammonia was less than the amount required for full production due to tons paid for but not taken by Orica, normal seasonal first quarter agricultural AN demand and lower nitric acid capacity in both periods due to the loss of the DSN plant in 2012. It is expected that this trend will continue in 2015 as El Dorado marketing continues to rebuild sales volumes after the Orica contract expiration, negatively impacted our operating results.

As mentioned above, our El Dorado Facility produces agricultural grade AN, nitric acid and industrial grade AN from purchased ammonia, which is currently at a cost disadvantage compared to products produced from natural gas. During the first quarter of 2015, the spread difference per ton between the ammonia purchased by the El Dorado Facility as compared to the cost had the facility produced ammonia using natural gas was approximately $290 per ton. This cost disadvantage resulted in an operating loss for the facility during the period of approximately $4 million.

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 fertilizer prices in the U.S. are influenced by the cost to transport product from exporting countries, giving domestic producers that transport shorter distances an advantage.

26

Climate Control Business

Construction Markets

Our Climate Control Business serves the new and renovation commercial/institutional and residential construction sectors, and we believe the majority of our business is associated with the construction of new facilities. Information available from the CMFS forecast indicates that construction activity in the commercial/institutional markets we serve (including multi-family residential structures) is expected to increase 7% in aggregate during 2015 and is near 2007 pre-recession levels and single-family residential construction is expected to grow 15% during 2015, however, still well below pre-recession levels. In particular, the hospitality, education and multi-family vertical end markets of the commercial/institutional sector are expected to grow faster than other vertical end markets we serve.

We expect the Climate Control Business to experience sales growth in the short-term. Although a part of the Climate Control Business’ commercial/institutional sales are products that are used for renovation and replacement applications, sales increases in the medium-term and long-term are expected to be primarily driven by growth in new construction, as well as the introduction of new products specifically in the hospitality, education and healthcare verticals end markets. Our expectations for our residential products, which are all GHPs, are that they will experience minimal growth due to the higher relative total system purchase cost of our higher efficiency GHP product offerings as compared to traditional HVAC systems creating a longer payback period in most regions due to low natural gas prices than in previous years with higher natural gas prices. We continue to focus our sales and marketing efforts to increase our share of the existing market for our products as well as expand the markets for and application of our products, especially 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 the market, 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. Going forward, we anticipate that Turnarounds at our Cherokee Facility typically will be performed every two years, expecting to last 25 to 30 days. Turnarounds at our Pryor Facility currently are performed every year, and typically last between 20 to 25 days. We are currently anticipating a Turnaround at our Pryor Facility in July of 2015. At our El Dorado Facility, since we are able to perform Turnaround projects on individual plants without shutting down the entire facility, we believe that the impact of lost production will be less significant. Upon completion of the new ammonia plant at our El Dorado Facility, that facility is expected to begin with annual Turnarounds that will typically 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 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’ first quarter 2015 total new product bookings were $66.5 million, an increase of 5% and 15% over the first and fourth quarters of 2014, respectively. Despite the loss of Carrier’s heat pump contracts as previously reported, our commercial bookings increased 7% over the first quarter 2014, whereas our residential product bookings declined 7%.

27

Excluding Carrier heat pump activity, commercial and residential bookings increased 19% and 15%, respectively. Our backlog significantly improved in 2015 over 2014 due to increased orders for our hydronic fan coils and larger custom air handlers as a result of increase quote activity in the vertical markets we serve.

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		2014
	(In Millions)
First Quarter	$	66.5	$	63.2	$	65.2	$	60.3	$	68.6	$	44.7
Second Quarter			$	83.1			$	62.8			$	68.1
Third Quarter			$	74.1			$	73.5			$	73.5
Fourth Quarter			$	58.0			$	68.8			$	64.9
Fiscal Year			$	278.4			$	265.4

(1) Our product order level consists of confirmed purchase orders from customers that have been accepted and received credit approval. Our backlog consists of confirmed customer orders for product to be shipped at a future date. Historically, we have not experienced significant cancellations relating to our backlog of confirmed customer product orders, and we typically expect to ship substantially all of these orders within the next twelve months. However, the March 31, 2015 backlog includes two orders totaling approximately $4.3 million expected to ship in 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 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 April 2015, our new orders received were approximately $22.0 million and our backlog was approximately $69.8 million at April 30, 2015.

Operational Excellence Activities

We are in the second full year of our operational excellence initiatives to become a world class company in terms of safety, quality, delivery and cost. We believe world class performance will benefit our Climate Control Business through a high level of customer satisfaction, enhanced employee engagement, faster growth and improved margins. During the past two years, we completed value analysis/value engineering activities that are part of our operational excellence initiatives at each of our companies within our Climate Control Business. In addition, we have laid the foundation for the continuous improvement culture desired in our organization. Key metrics include measurements and targets for sales volume, material, direct labor, safety, quality, delivery and asset management.

The following Results of Operations should be read in conjunction with our condensed consolidated financial statements for the three months ended March 31, 2015 and 2014 and accompanying notes and the discussions under “Overview” and “Liquidity and Capital Resources” included in this MD&A.

We present the following information about our results of operations for our two core business segments: the Chemical Business and the Climate Control Business. The business operation classified as “Other” primarily sells industrial machinery and related components to machine tool dealers and end users. Net sales by business segment include net sales to unaffiliated customers as reported in the consolidated financial statements. Intersegment net sales are not significant. Gross profit by business segment represents net sales less cost of sales. In addition, our chief operating decision makers use operating income by business segment for purposes of making decisions that include resource allocations and performance evaluations. Operating income by business segment represents gross profit by business segment less 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.

(1) As a percentage of net sales

Net Sales – Chemical

Our Chemical Business sales in the agricultural markets were primarily 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 first quarter 2015 production and sales volumes were higher in the agricultural products market and stable in our other two primary markets due to consistent customer demand and improved on-stream production rates at the Pryor and Cherokee Facilities.

• Agricultural products comprised approximately 54% and 52% of the Chemical Business’ net sales for the first quarter 2015 and 2014, respectively. Agricultural products sales increased during the first quarter of 2015 as more product was available to sell resulting from the increased on-stream rate of our Pryor and Cherokee Facilities and a higher average selling price for sales of nitrogen fertilizers. Compared to the first quarter of 2014, the 2015 overall average agricultural products selling prices per ton increased by 2%, driven by a 22% increase in ammonia prices and a 2% increase in AN prices partially offset by a 4% decrease in UAN prices. The decrease in selling prices for UAN fertilizers was attributable to lower commodity prices coupled with lower urea prices due to the large amount of imports.

• Industrial acids and other chemical products sales increased as a result of higher prices from the pass-through of increased ammonia costs to contractual customers partially offset by lower volumes at our Baytown Facility.

• Mining products sales increased primarily as a result of higher prices from the pass-through of increased ammonia costs to our contractual customers partially offset by lower volumes at our Cherokee Facility.

• 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 sales prices and lower production volumes as the operator of these properties is delaying development due to the current low net selling prices of natural gas in the Marcellus Shale region.

30

Gross Profit - Chemical

• Our gross profit decreased $6.6 million during the first quarter of 2015 as compared to the first quarter of 2014. The first quarter of 2014 included a business interruption insurance recovery of $22.9 million. Excluding the business interruption insurance recovery, gross profit increased $16.3 million quarter over quarter. The increase of $16.3 million was due to the higher sales level made possible by the improved on-stream production rate of our Pryor and Cherokee Facilities and higher average sales prices coupled with lower feedstock costs. Natural gas feedstock costs decreased approximately 28% partially offset by a 16% increase in ammonia feedstock costs.

• Unrealized losses related to forward contracts on natural gas purchases decreased 2015 gross profit by $1.2 million for the first quarter of 2015 compared to a $0.7 million unrealized gain in the same period in 2014.

Operating Income - Chemical

• Our Chemical Business’ operating income was $16.7 million, a decrease of $12.2 million. In addition to the business interruption insurance recovery included in gross profit discussed above, a property insurance recovery of $5.1 million was recognized in the first quarter of 2014. Excluding the total insurance recoveries of $28.0 million in the first quarter of 2014, operating income increased $15.8 million primarily as the result of the items discussed above.

Climate Control Business

The following table contains certain information about our net sales, gross profit and operating income in our Climate Control segment for the three months ended March 31,

(1) As a percentage of net sales

Net Sales – Climate Control

• Net sales of our water source and geothermal heat pump products decreased in the first quarter of 2015 primarily as a result of the loss of the Carrier heat pump contracts. Excluding Carrier heat pump sales, sales increased from $32.2 million in the first quarter of 2014 to $37.3 million in the first quarter of 2015, or 16%, with commercial/institutional product sales up 14% and residential product sales up approximately 22%. Overall, the number of units sold declined but 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. Incoming orders, excluding Carrier, for commercial/institutional products and residential products increased 11% and 15%, respectively.

• Net sales of our hydronic fan coils increased as a result of an increase number of units sold and favorable product mix. We experienced only minor fluctuations in the vertical markets served.

31

• Net sales of our other HVAC products increased primarily due to increased sales of our large custom air handlers and modular chillers, up 95% and 50%, respectively. In both areas, incoming order levels and customer requested product delivery dates during 2014 resulted in higher beginning backlogs in 2015 and facilitated higher sales during 2015. From a vertical market perspective, there were no significant shifts in the sectors served.

Gross Profit - Climate Control

• The increase in gross profit in our Climate Control Business was primarily the result of the higher sales discussed above. The lower gross profit as a percentage of sales was primarily the result of product mix as residential products, which carry a higher gross margin declined in proportion to commercial/institutional products and as margins on large custom air handlers are lower than those of other product lines.

Operating Income - Climate Control

• Operating income in the first quarter of 2015 was basically flat compared to the same period of 2014. The increase in gross profit was offset by higher variable selling expenses. The higher variable selling expenses were caused primarily by a change in product, distribution channel and customer mix with lower OEM sales at CM causing freight and commissions to increase as a percentage of sales partially offset by lower warranty expenses in the first quarter of 2015. Fixed expenses for the first quarter of 2015 were consistent with the same period of 2014.

Interest Expense, net

Interest expense for the first quarter of 2015 was $3.4 million compared to $6.7 million for the same period in 2014. The decrease is due primarily to capitalized interest on capital projects under development and construction during 2015 of $5.6 million compared to $2.3 million capitalized during 2014.

Provision for Income Taxes

The provision for income taxes for the first quarter of 2015 was approximately $4.2 million compared to $7.7 million for the same period in 2014. The resulting effective tax rate for the first quarters of 2015 and 2014 was 39% and 40%.

Liquidity and Capital Resources

Historically, our primary cash needs have been for operating expenses, working capital and capital expenditures. We have financed our cash requirements primarily through internally generated cash flow and various forms of financing. See additional discussions concerning cash flow relating to our Chemical and Climate Control Businesses under “Overview” and “Results of Operations included in this MD&A. Before discussing our capitalization and capital projects in detail, the following summarizes our cash flow activities for the three months ended March 31, 2015:

Cash Flow from Continuing Operating Activities

Net cash provided by continuing operating activities was $12.6 million primarily as the result of net income of $6.6 million plus adjustments of $9.0 million for depreciation, depletion and amortization of PP&E.

Cash Flow from Continuing Investing Activities

Net cash used by continuing investing activities was $31.9 million that consisted primarily of $66.8 million used for expenditures for PP&E primarily for the benefit of our Chemical Business and purchases of short-term investments of $10.0 million, partially offset by proceeds of $46.0 million from restricted cash and cash equivalents primarily representing cash designated by management for specific capital projects relating to our Chemical Business.

Cash Flow from Continuing Financing Activities

Net cash used by continuing financing activities was $5.9 million that primarily related to payments on short-term financing and long-term debt.

Capitalization

The following is our cash and cash equivalents, noncurrent restricted cash and investments, long-term debt and stockholders’ equity:

	March 31, 2015		December 31, 2014
	(In Millions)
Cash and cash equivalents and short-term investments	$	186.1	$	201.3
Noncurrent restricted cash and cash equivalents and investments (1)		25.0		71.0
Total current and noncurrent cash and investments	$	211.1	$	272.3
Long-term debt:
Senior Secured Notes	$	425.0	$	425.0
Secured Promissory Note		21.1		22.8
Other		9.6		9.5
Total long-term debt, including current portion	$	455.7	$	457.3
Total stockholders’ equity	$	441.9	$	434.0

(1) At March 31, 2015, this balance includes a certificate of deposit with an original maturity no longer than approximately 26 weeks. We have designated this balance for specific purposes relating to capital projects. All of these investments were held by financial institutions within the U.S.

As of March 31, 2015, our current and noncurrent cash and investments totaled $211.1 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.

For the remainder of 2015, we have extensive planned capital expenditures. Our primary cash needs for this period of time will be to fund our planned capital spending program, as well as our operations, our general obligations, and our interest payment requirements. Based upon our projections for 2015, we expect to fund these cash needs from working capital, the noncurrent restricted investments (provided from the proceeds from the Senior Secured Notes), internally generated cash flows, and third-party financing. In April 2015, we received approximately $16 million to finance a natural gas pipeline being constructed at our El Dorado Facility. We are currently in discussion with certain lenders to finance two other separately identifiable pieces of equipment that are included in the planned expansion project. We are in final discussions regarding financing $21 million related to the construction of a cogeneration facility and $20 million related to the construction of an ammonia storage tank at our El Dorado Facility, subject to the terms of our existing loan agreements, including the Senior Secured Notes. We believe that neither the Senior Secured Notes nor the Amended Working Capital Revolver Loan will preclude us from entering into the additional borrowings. See additional discussions below under “Capital Additions”. Our internally generated cash flows and liquidity have been, and could be, affected by possible declines in sales volumes resulting from the uncertainty regarding current economic conditions and production inefficiency of our facilities.

We are party to an Indenture governing the Senior Secured Notes. The Indenture contains covenants that, among other things, limit LSB’s ability, with certain exceptions and as defined in the Indenture, to certain transactions.

We and certain of our subsidiaries are party to an amended and restated revolving credit facility. Pursuant to the terms of the Amended Working Capital Revolver Loan, the principal amount the Borrowers may borrow is up to $100.0 million, based on specific percentages of eligible accounts receivable and inventories. At March 31, 2015, there were no outstanding borrowings under the Amended Working Capital Revolver Loan and the net credit available for borrowings was approximately $75.6 million, based on our eligible collateral, less outstanding letters of credit as of that date.

Capital Additions

Capital Additions – First Quarter of 2015

Capital additions during the first quarter of 2015 were $78.5 million, including $76.7 million for the benefit of our Chemical Business. The Chemical Business capital additions included $69.1 million for expansion projects at our El Dorado Facility, approximately $5.0 million associated with maintaining compliance with environmental laws, regulations and guidelines, approximately $3.8 million for various major renewal and improvement projects, and $1.3 million for the development of natural gas leaseholds. The capital additions were funded primarily from noncurrent restricted cash and investments 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 continue to increase during 2015 and future years.

Planned Capital Additions

	Planned Capital Additions For the Remainder of 2015
	(In Millions)
Chemical:
El Dorado Facility Expansion Projects	$	162	–	$	187
Development of Natural Gas Leaseholds		2	–		4
Environmental Projects		14	–		18
Major Renewal and Improvement Projects		19	–		22
Other (1)		20	–		25
Total Chemical	$	217	–	$	256
Climate Control		5	–		10
Corporate and Other		5	–		10
	$	227	–	$	276

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

Included in planned capital expenditures is capitalized interest of approximately $14.9 million for the remainder of 2015. The planned capital expenditures for Corporate and Other are primarily for the replacement of our enterprise resource planning, 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 2016 at a total cost of $25.0 million to $27.0 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. These capital expenditures are subject to economic conditions, which are continually reviewed by us, and may increase or decrease as new information is obtained or circumstances change. We plan to fund the planned capital expenditures from working capital, noncurrent cash and investments, internally generated cash flows, and third-party financing.

As discussed below, the construction of the El Dorado Expansion projects are expected to be completed by the end of 2015. Beyond 2015, specific capital projects are less identified but are expected to include approximately $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 $28 million from 2016-2019 to fully develop our natural gas working interests. We plan to fund these expenditures from working capital, internally generated cash flows, and possibly third-party financing.

34

El Dorado Facility Expansion Projects

The El Dorado Facility has certain expansion projects underway. 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, which planned amounts are included in the table above.

	Capitalized To Date		Planned Capital Additions For the Remainder of 2015					Total
			(In Millions)
Ammonia Plant	$	172	$	113	–	$	128	$	285	–	$	300
Nitric Acid Plant and Concentrator		105		20	–		25		125	–		130
Other Support Infrastructure		56		29	–		34		85	–		90
	$	333	$	162	–	$	187	$	495	–	$	520

Our El Dorado Facility produces nitric acid and agricultural and industrial grade AN from purchased ammonia, which is currently at a cost disadvantage compared to products produced from natural gas. 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 should eliminate the cost disadvantage, increase capacity, and improve efficiency of the El Dorado Facility. The construction of this project is expected to be complete in late 2015 and operational in early 2016.

In addition, we are constructing a new 1,100 ton per day, 65% strength nitric acid plant and concentrator to replace the concentrated nitric acid capacity lost in May 2012. These plants are scheduled to begin production in the third quarter of 2015 and 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.

Plant Turnarounds

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 result in lost contribution margin, increased maintenance expense and decreased inventory for sale. The financial impact of planned downtime, such as major Turnaround maintenance, is mitigated through a diligent planning process that takes into consideration the market, the availability of resources to perform the needed maintenance, feedstock logistics and other factors. Based on our current plan for Turnarounds for the remainder of 2015, we estimate that we will incur approximately $1.8 million to $2.3 million of these Turnaround costs. However, it is possible that the actual costs could be significantly different from our estimates.

Expenses Associated with Environmental Regulatory Compliance

Our Chemical Business is subject to specific federal and state environmental compliance laws, regulations and guidelines. As a result, our Chemical Business incurred expenses of $1.3 million in the first quarter of 2015 in connection with environmental projects. For the remainder of 2015, we expect to incur expenses ranging from $3.6 million to $4.1 million in connection with additional environmental projects. However, it is possible that the actual costs could be significantly different than our estimates, including costs relating to a corrective action study work plan approved by the KDHE discussed under footnote 3 – Other Environmental Matters of Note 9 of Notes to Condensed Consolidated Financial Statements.

Fees and Expenses Related to Shareholders

For the first quarter of 2015 and 2014, we incurred shareholder-related fees and expenses of $1.7 million and $4.2 million, respectively. These fees and expenses include costs associated with evaluating and analyzing proposals received from certain

35

activist shareholders and dealing, negotiating and settling with those shareholders in order to avoid proxy contests. For the second quarter of 2015, we currently estimate that these expenses will range between $1.5 million to $2.0 million.

Dividends

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

Holders of our common stock and preferred stocks are entitled to receive dividends only when and if declared by our Board of Directors. We have not paid cash dividends on our outstanding common stock in many years, and we do not currently anticipate paying cash dividends on our outstanding common stock in the near future. However, our Board of Directors has not made a decision whether or not to pay such dividends on our common stock in 2015.

During the first quarter of 2015, dividends totaling $300,000 were declared and paid on our outstanding preferred stock using funds from our working capital. Each share of preferred stock is entitled to receive an annual dividend, only when declared by our Board of Directors, payable as follows:

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

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

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

Compliance with Long - Term Debt Covenants

The Amended Working Capital Revolver Loan requires, among other things, that we meet certain financial covenants, including a minimum fixed charge coverage ratio of not less than 1.10 to 1, if at any time the excess availability (as defined by the Amended Working Capital Revolver Loan), under the Amended Working Capital Revolver Loan, is less than or equal to $12.5 million. This ratio will be measured monthly on a trailing twelve month basis and as defined in the agreement. As of March 31, 2015, as defined in the agreement, the fixed charge coverage ratio was 3.7 to 1. Currently, our forecast is that we will be able to meet all financial covenant requirements for the next twelve months.

Seasonality

We believe chemical products sold by our Chemical Business to the agricultural industry are seasonal while sales into the industrial and mining sectors 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.

Related Party Transactions

See discussion above under “Liquidity and Capital Resources-Dividends” relating to the Golsen Group.

Critical Accounting Policies and Estimates

See our discussion on critical accounting policies and estimates in Item 7 of our 2014 Form 10-K. In addition, the preparation of financial statements requires management to make estimates and assumptions that affect the reported amount of assets, liabilities, revenues and expenses, and disclosures of contingencies and fair values. For the first quarter of 2015, we did not experience a material change in accounting estimates. However, it is reasonably possible that the estimates and assumptions utilized as of March 31, 2015 could change in the near-term.

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

36

performance of our subsidiaries. As of March 31, 2015, we have agreed to indemnify the sureties for payments, up to $11.0 million, made by them in respect of such bonds. All of these insurance bonds are expected to expire or be renewed in 2015.

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.

Aggregate Contractual Obligations

In the operation of our businesses, we enter into contracts, leases and borrowing arrangements. As discussed in our 2014 Form 10-K, we had certain contractual obligations as of December 31, 2014, with various maturity dates, showing payments due for the next five years and thereafter related to the following:

• long-term debt,

• interest payments on long-term debt,

• interest rate contracts,

• El Dorado facility expansion projects,

• other capital expenditures,

• operating leases,

• natural gas pipeline commitment,

• firm purchase commitments and,

• other contractual obligations.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

General

Our results of operations and operating cash flows are impacted by changes in market prices of copper, steel, ammonia and natural gas, 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 March 31, 2015, we had a minimal amount of embedded losses associated with sales commitments with firm sales prices relating to our Chemical Business.

Commodity Price Risk

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

Certain subsidiaries within the Chemical Business entered into contracts to purchase natural gas for anticipated production needs. A portion of these contracts are considered derivatives and are accounted for on a mark-to-market basis and a portion of these contracts are considered normal purchases because they provide for the purchase of natural gas that will be delivered in quantities expected to be used over a reasonable period of time in the normal course of business and are documented as such. These contracts are exempt from the accounting and reporting requirements relating to derivatives.

At March 31, 2015, the natural gas contracts accounted for on a mark-to-market basis were for approximately 6.4 million MMBtu of natural gas. These contracts extend through June 2016 (includes contractual costs indexed to future NYMEX prices) at a weighted-average cost of $3.09 per MMBtu ($19.8 million) and a weighted-average market value of $2.73 per MMBtu ($17.5 million).

37

At March 31, 2015, our futures/forward natural gas contracts which are exempt from mark-to-market accounting included the firm purchase commitments of approximately 2.4 million MMBtu of natural gas. These contracts extend through December 2015 at a weighted-average cost of $3.20 per MMBtu ($7.6 million) and a weighted-average market value of $2.78 per MMBtu ($6.6 million).

At March 31, 2015, our platinum contracts, which are accounted for on a mark-to-market basis, included 3,000 ounces of platinum, extend through July 2015 at a weighted-average cost of $1,120.87 per ounce ($3.36 million) and a weighted-average market value of $1,143.40 per ounce ($3.43 million).

At March 31, 2015, our futures/forward copper contracts, which are accounted for on a mark-to-market basis, included 1,950,000 pounds of copper, extend through December 2015 at a weighted-average cost of $2.96 per pound ($5.8 million) and a weighted-average market value of $2.74 per pound ($5.3 million).

Interest Rate Risk

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

As part of our interest rate risk management, we periodically purchase and/or enter into various interest rate contracts. At March 31, 2015, we have an interest rate swap, which sets a fixed three-month LIBOR of 3.23% on a declining balance (from $23.8 million to $18.8 million) for the period beginning April 2012 through March 2016. This contract is a free-standing derivative and is accounted for on a mark-to-market basis. At March 31, 2015, the fair value of these contracts (unrealized loss) was $0.6 million.

At March 31, 2015, we did not have any financial instruments with fair values significantly different from their carrying amounts, except for the Senior Secured Notes. At March 31, 2015, the estimated fair value of the Senior Secured Notes exceeded the carrying value by approximately $17 million based on a quoted price of 104.0. This valuation is 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 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 4. Controls and Procedures

As of the end of the period covered by this report, we carried out an evaluation, with the participation of our Principal Executive Officer and Principal Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15 under the Securities Exchange Act of 1934). Based upon that evaluation, our Principal Executive Officer and our Principal Financial Officer have concluded that our disclosure controls and procedures were effective. There were no changes to our internal control over financial reporting during the quarter ended March 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 enterprise resource planning 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. While we expect that our internal controls over financial reporting will remain largely similar or unchanged, 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.

Section 2. Annual Meeting. Annual meetings of stockholders to elect directors and transact such other business as may properly be presented to the meeting shall be held on the last Tuesday in June of each year if not a legal holiday, and if a legal holiday, then on the next secular day following, at 10:00 a.m., or if the annual meeting is not held on the above designated date, then the directors shall cause the annual meeting to be held as soon thereafter as is convenient.

Section 3. Quorum. The holders of record of a majority of the stock issued and outstanding, and entitled to vote thereat, present in person, or represented by proxy, shall be requisite and shall constitute a quorum at all meetings of the stockholders for the transaction of business, except as otherwise provided by law, by the Certificate of Incorporation or by these Bylaws, but in the absence of a quorum the holders of record, present in person or represented by proxy at such meeting shall have power to adjourn the meeting from time to time, without notice other than announcement at the meeting, until the requisite amount of voting stock shall be present. At such adjourned meeting at which the requisite amount of voting stock shall be represented, any business may be transacted which might have been transacted at the meeting as originally notified.

Section 4. Voting; Proxies. Except as otherwise provided by the laws of the State of Delaware or the Certificate of Incorporation of the Corporation or these Bylaws:

(a) At every meeting of the stockholders every shareholder having the right to vote shall be entitled to one vote for each share of capital stock having voting rights held by him.

(b) Each stockholder entitled to vote at a meeting of stockholders or to express consent or dissent to corporate action in writing without a meeting may authorize another person or persons to act for him by proxy, but no such proxy shall be voted or acted upon after three years from its date, unless the proxy provides for a longer period.

(c) Each matter properly presented to any meeting shall be decided by a majority of the votes cast on the matter.

(d) Election of directors and the vote on any other matter presented to a meeting need not be by written ballots, but written ballots may be used if ordered by the chairman of the meeting or if so requested by any stockholder present or represented by proxy at the meeting entitled to vote in such election or on such matter, as the case may be.

Section 5. Notice of Meeting. For each meeting of stockholders written notice shall be given stating the place, date and hour, and, in the case of a special meeting, the purpose or purposes for which the meeting is called and, if the list of stockholders required by Section 6 is not to be at the place of said meeting at least 10 days prior to the meeting, the place where said list will be. Except as otherwise provided by Delaware law, the written notice of any meeting shall be given not less than 10 nor more than 60 days before the date of the meeting to each stockholder entitled to vote at such meeting. If mailed, notice shall be deemed to be given when deposited in the United States mail, postage prepaid, directed to the stockholder at his address as it appears on the records of the Corporation.

Section 6. List of Stockholders Entitled to Vote. At least 10 days before every meeting of stockholders a complete list of the stockholders entitled to vote at the meeting, arranged in alphabetical order, and showing the address of each stockholder and the number of shares registered in the name of each stockholder, shall be prepared and shall be open to the examination of any stockholder for any purpose germane to the meeting, during ordinary business hours, for a period of at least 10 days prior to the meeting, either at a place within the city where the meeting is to be held, which place shall be specified in the notice of the meeting, or, if not so specified, at the place where the meeting is to be held.

2

meeting was the close of business on the preceding day. Any such meeting shall be held at such time and at such place, within or without the State of Delaware, as shall be determined by the body or person calling such meeting and as shall be stated in the notice of such meeting.”

Section 8. Chairman and Secretary at Meeting. At each meeting of stockholders, the Chairman of the Board of Directors or, in the absence or inability to serve by the Chairman of the Board of Directors, the Vice Chairman of the Board of Directors or, in the absence or inability to serve by both the Chairman of the Board of Directors and the Vice Chairman of the Board of Directors, the President or, in the absence or inability to serve by the Chairman of the Board of Directors, Vice Chairman of the Board of Directors and the President, the person designated in writing by the President or, if no person is so designated, then a person designated by the Board of Directors shall preside as Chairman of the meeting; if no person is so designated, then the Board of Directors shall choose a Chairman by plurality vote. The Secretary or in his absence a person designated by the Chairman of the meeting shall act as Secretary of the meeting.

Section 9. Adjourned Meetings. A meeting of stockholders may be adjourned to another time or place as provided in Sections 3 or 4(d) of this Article III. Unless the Board of Directors fixes a new record date, stockholders of record for an adjourned meeting shall be as originally determined for the meeting from which the adjournment was taken. If the adjournment is for more than 30 days, or if after the adjournment, a new record date is fixed for the adjourned meeting, a notice of the adjourned meeting shall be given to each stockholder of record entitled to vote. At the adjourned meeting any business may be transacted that might have been transacted at the meeting as originally called.

Section 10. Consent of Stockholders in Lieu of Meeting.

10.1 Action by Written Consent. Any action which is required to be or may be taken at any annual or special meeting of stockholders of the Corporation may be taken without a meeting, without prior notice and without a vote, if consents in writing, setting forth the action so taken, shall have been signed by the holders of outstanding stock having not less than the minimum number of votes that would be necessary to authorize or to take such action at a meeting at which all shares entitled to vote thereon were present and voted; provided however, that prompt notice of the taking of the corporate action without a meeting and by less than unanimous written consent shall be given to those stockholders who have not consented in writing.

10.2 Determination of Record Date of Action by Written Consent. In order to inform the Corporation’s stockholders and the investing public in advance that a record date for action by consent will occur and to comply with the procedures contained in the New York Stock Exchange (or such other exchange on which the Corporation’s securities are listed for trading) policies and rules, the record date for determining stockholders entitled to express consent to corporate action in writing without a meeting is fixed by the Board of Directors of the Corporation pursuant to Section 213 of the Delaware General Corporation Law as follows: The Board of Directors shall set as the record date the 10th day after (i) any stockholder of record seeking to have the stockholders authorize or take corporate action by written consent without a

3

meeting shall, by written notice to the Secretary which may be given by telex or telecopy, advise the Corporation of the corporate action proposed for which consents will be sought and request from the Board of Directors a record date unless a later date is specified by such stockholder, or (ii) the Board of Directors determines that the Corporation should seek corporate action by written consent, unless a later record date is specified in the resolution of the Board of Directors containing such determination. In the event that the record date set as provided falls on a Saturday, Sunday or legal holiday, the record date shall be the first day next following such date that is not a Saturday, Sunday or legal holiday. Any record date determined pursuant to this Subsection 10.2 shall be announced by a press release prior to the opening of trading on the New York Stock Exchange (or such other exchange on which the Corporation’s securities are listed for trading) on the next trading day after a request for a record date pursuant to clause (i) above is received by the Secretary or a Board of Directors’ determination pursuant to clause (ii) above.

10.3 Duration and Revocation of Consents. In order that the Corporation’s stockholders shall have an opportunity to receive and consider the information germane to an informed judgment as to whether to give a written consent and in accordance with the procedures contained in the New York Stock Exchange (or such other exchange on which the Corporation’s securities are listed for trading) policies and rules, the stockholders of the Corporation shall be given at least 20 days from the record date to give or revoke written consents. Consents to corporate action shall be valid for a maximum of 60 days after the record date. Consents may be revoked by written notice (i) to the Corporation, (ii) to the stockholder or stockholders soliciting consents or soliciting revocations in opposition to action by consent proposed by the Corporation (the “Soliciting Stockholders”), or (iii) to a proxy solicitor or other agent designated by the Corporation of the Soliciting Stockholder(s).

10.4 Retention and Duties of Inspectors of Election. Within two business days after receipt of a request by a stockholder for the setting of a record date or a determination by the Board of Directors that the Corporation should seek corporate action by written consent, as the case may be, the Secretary of the Corporation shall engage nationally recognized independent inspectors of elections for the purpose of performing a ministerial review of the validity of the consents and revocations. The inspectors shall review all consents and revocations, determine whether the requisite number of valid and unrevoked consents has been obtained to authorize or take the action specified in the consents, and forthwith certify such determination for entry in the records of the Corporation kept for the purpose of recording the proceedings of meetings of stockholders. The cost of retaining inspectors of elections shall be borne by the party proposing the action by consent.

10.5 Procedures for Counting and Challenging Consents. Consents and revocations shall be delivered to the inspectors upon receipt by the Corporation, the Soliciting Stockholders or their proxy solicitors or other designated agents. As soon as consents and revocations are received, the inspectors shall review the consents and revocations and shall maintain a count of the number of valid and unrevoked consents. The inspectors shall keep such count confidential and shall not reveal the count to the Corporation, the Soliciting Stockholders or their representatives. As soon as practicable after the earlier of (i) 60 days after the record date for the consents or (ii) a request therefore by the Corporation or the Soliciting Stockholders (whichever is soliciting consents) made after expiration of the period for giving or revoking consents under

4

Subsection 10.3 above, notice of which request shall be given to the party opposing the solicitation of consents, which request shall state that the Corporation or Soliciting Stockholder(s) (as the case may be) in good faith believe that it or they have received the requisite number of valid and unrevoked consents to authorize or take the action specified in the consents, the inspectors shall issue a preliminary report to the Corporation and the Soliciting Stockholders stating:

(i) The number of valid consents;

(ii) The number of valid revocations;

(iii) The number of valid and unrevoked consents;

(iv) The number of invalid consents;

(v) The number of invalid revocations;

(vi) Whether, based on their preliminary count, the requisite number of valid and unrevoked consents has been obtained to authorize or take the action specified in the consents.

Unless the Corporation and the Soliciting Stockholder(s) shall agree to a shorter or longer period, the Corporation and the Soliciting Stockholder(s) shall have 48 hours to review the consents and revocations and to advise the inspectors and the opposing party in writing as to whether they intend to challenge the preliminary report of the inspectors. If no written notice of an intention to challenge the preliminary report is received within 48 hours after the inspector’s issuance of the preliminary report, the inspectors shall issue to the Corporation and the Soliciting Stockholder(s) their final report containing the information from the inspectors’ determination with respect to whether the requisite number of valid and unrevoked consents was obtained to authorize and take the action specified in the consents. If the Corporation or the Soliciting Stockholder(s) issue written notice of an intention to challenge the inspectors’ preliminary report within 48 hours after the issuance of that report, a challenge session shall be scheduled by the inspectors as promptly as practicable. A transcript of the challenge session shall be recorded by a certified court reporter. Following completion of the challenge session, the inspectors shall as promptly as practicable issue their final report to the Corporation and the Soliciting Stockholder(s) containing the information included in the preliminary report, plus all changes in the vote totals as a result of the challenges and a certification of whether the requisite number of valid and unrevoked consents was obtained to authorize or take the action specified in the consents.

10.6 Notice of Results. The Corporation shall give prompt notice to the stockholders of the results of any consent solicitation or the taking of the corporate action without a meeting and by less than unanimous written consent.

Section 11. Fixing of Record Date. In order that the Corporation may determine the stockholders entitled to notice of or to vote at any meeting of stockholders or any adjournment

5

thereof, or to express consent to corporate action in writing without a meeting, or entitled receive payment of any dividend or other distribution or allotment of any rights, or entitled to exercise any rights in respect of any change, conversion or exchange of stock or for the purpose of any other lawful action, the Board of Directors may fix, in advance, a record date, which shall not be more than 60 nor less than 10 days before the date of such meeting, nor more than 60 days prior to any other action. If no record date is fixed, the record date for determining stockholders entitled to notice of or to vote at a meeting of stockholders shall be at the close of business on the day next preceding the day on which notice is given or, if notice is waived, at the close of business on the day next preceding the day on which the meeting is held; the record date for determining stockholders entitled to express consent to corporate action in writing without a meeting, when no prior action by the Board of Directors is necessary, shall be the day on which the first written consent is expressed; and the record date for determining stockholders for any other purpose shall be at the close of business on the day on which the Board of Directors adopts the resolution relating thereto.

Section 12. Business to be Conducted at the Annual or Special Meeting of the Stockholders; Notice of Proposals. At any annual meeting of the stockholders, only such business shall be conducted as shall have been brought before the meeting (i) by or at the direction of the Board of Directors, or (ii) by any stockholder of the Corporation who is entitled to vote with respect thereto and who: (a) was a stockholder of record (and, with respect to any beneficial owner, if different, on whose behalf such business as proposed, only if such beneficial owner was the beneficial owner of shares of the Corporation) both at the time of giving notice provided for in this Section 12 and at the time of the meeting; and (b) complies with the notice procedures set forth in this Section 12.

Except for proposals properly made in accordance with Rule 14a-8 under the Securities Exchange Act of 1934, as amended, and the rules and regulations thereunder (as so amended and inclusive of such rules as regulations, the “Exchange Act”) and included in the notice of the meeting given by or at the direction of the Board of Directors, the foregoing clause (ii) will be the exclusive means for a stockholder to propose business to be brought before the annual meeting of stockholders.

For business to be properly brought before the annual meeting by a stockholder, the Proposing Person (as defined below) must have given timely notice thereof in writing to the Secretary of the Corporation. The Proposing Person’s notice will be timely if delivered or mailed to and received at the principal executive offices at the Corporation not less than 120 nor more than 150 days before the date on which the Corporation first mailed its proxy materials for the prior year’s annual meeting of stockholders; provided however, that if the date of the annual meeting is more than 30 days before or more than 60 days after such date, notice by the stockholder timely must be so delivered, or mailed and received not later than the 90^th day prior to such annual meeting, or if later, the 10^th day following the date on which the public disclosure of the date of such annual meeting was such made. Any adjournment of an annual meeting or the announcement hereof will not commence a new time period for giving the notice described above.

6

The Proposing Person’s notice to the Secretary shall set forth as to each matter such stockholder proposes to bring before the annual meeting, the following:

(i) the name and address, as they appear on the Corporation books, of the stockholder proposing such business;

(ii) the class or series and number of shares of the Corporation’s securities that are, directly or indirectly, owned of record or beneficially owned (within the meaning of Rule 13d-3 under the Exchange Act) by the Proposing Person, except the Proposing Person will be deemed to beneficially own any shares or class or series of the Corporation’s securities which the Proposing Person has a right to acquire beneficially ownership at any time in the future (collectively, the “Stockholder Information”);

(iii) as to each item of business that the stockholder proposes to bring before the annual meeting, (A) a reasonably brief description of the business desired to be brought before the annual meeting, the reasons for conducting such business at the annual meeting and any material interest in such business of each Proposing Person, (B) the text of the proposal or business (including the text of any resolutions proposed for consideration), and

(iv) a reasonably detailed description of all agreements, arrangements and understandings, oral or in writing (x) between or among any of the Proposing Persons or (y) between or among any Proposing Person and any other record or beneficial holder of the shares of any class or series of the Corporation (including their names) in connection with the proposal of such business by such stockholder or (z) between or among any Proposing Person and any other persons or entities (including their names) acting in concert with the Proposing Person.

For purposes of this Section 12, the term “Proposing Person” shall mean (i) the stockholder providing the notice of business proposed to be brought before an annual meeting, (ii) the beneficial owner or beneficial owners, if different, on whose behalf the notice of the business proposed to be brought before the annual meeting is made, and (iii) any affiliate or associate (each within the meaning of Rule 12b-2 under the Exchange Act for purposes of these Bylaws) of such stockholder or beneficial owner; and (iv) any material interest of such stockholder with respect to such business.

Notwithstanding anything in these Bylaws to the contrary, no business (other than nominations of directors, which must be made in compliance with, and shall be exclusively governed by, Article III, Section 13 of these Bylaws) shall be brought before or conducted at the annual meeting except in accordance with the provisions of this Section 12. The officer of the Corporation or other person presiding over the annual meeting shall, if the facts so warrant, determine and declare to the meeting that business was not properly brought before the meeting in accordance with the provisions of this Section 12 and, if he should so determine, he shall so declare to the meeting and any such business so determined to be not properly brought before the meeting shall not be transacted.

7

A stockholder providing notice of business proposed to be brought before an annual meeting shall further update and supplement such notice, as needed, so that the information provided or required to be provided in such notice pursuant to this Section 12 shall be true and correct as of the record date for the meeting and as of the date that is 10 business days prior to the meeting or any adjournment or postponement thereof, and such update and supplement shall be delivered to, or mailed and received by, the Secretary of the Corporation at the principal executive offices of the Corporation not later than five business days after the record date for the meeting (in the case of the update and supplement required to be made as of the record date), and not later than eight business days prior to the date for the meeting (in the case of the update and supplement required to be made as of 10 business days prior to the meeting or any adjournment or postponement thereof).

This Section 12 is expressly intended to apply to any business proposed to be brought before an annual meeting of stockholders; except this Section 12 shall not apply to any proposal made pursuant to Rule 14a-8 of the Exchange Act, or to the nomination of persons for election to the Corporation’s Board of Directors at a meeting of stockholders at which directors are to be elected which shall be governed by Article III, Section 13 of these Bylaws. In addition to the requirements of this Section 12 with respect to any business proposed to be brought before an annual meeting, each Proposing Person shall comply with all applicable requirements of the Exchange Act with respect to any such business. Nothing in this Section 12 shall be deemed to affect the rights of stockholders to request inclusion of proposals in the Corporation’s proxy statement pursuant to Rule 14a-8 under the Exchange Act.

For purposes of these Bylaws, “public disclosure” shall mean disclosure in a press release reported by a national news service or in a document publicly filed by the Corporation with the Securities and Exchange Commission pursuant to Sections 13, 14 or 15(d) of the Exchange Act.

The officer of the Corporation or other person presiding at the meeting shall, if the facts so warrant, determine that business was not properly brought before the meeting in accordance with the procedures set forth in this Section 12, and, if he or she should so determine, he or she shall so declare to the meeting and any such business not properly brought before the meeting shall not be transacted.

At any special meeting of the stockholders, only such business shall be conducted as shall have been brought before the meeting by or at the direction of the Board of Directors.

Section 13. Election to the Board of Directors.

13.1 Only persons who are nominated in accordance with the procedures set forth in these Bylaws shall be eligible for election as directors of the Corporation. Nominations of persons for election to the Board of Directors of the Corporation may be made at a meeting of stockholders at which directors are to be elected only:

(i) By or at the direction of the Board of Directors; or

(ii) By any stockholder of the Corporation entitled to vote for the election of directors at the meeting who complies with the notice procedures set forth in Subsection 13.2 below.

8

The foregoing clause (ii) will be the exclusive means by which a stockholder may nominate a person for election to the Board of Directors.

13.2 Nominations of election as a director of the Corporation, other than those made by or at the direction of the Board of Directors, shall be made by timely notice in writing to the Secretary of the Corporation. To be timely, a stockholder’s notice shall be delivered or mailed to and received at the principal executive offices of the Corporation not less than 120 nor more than 150 days prior to the anniversary date of the Corporation’s immediately preceding annual meeting of stockholders; provided, however, that in the event the date of the annual meeting is more than 30 days before or more than 60 days after such date, notice by the stockholder to be timely must be so delivered, or mailed and received not later than the 90^th day prior to such annual meeting, or if later, the 10^th day following the date on which the public disclosure of the date of such annual meeting was so made. Any adjournment of an annual meeting or the announcement hereof will not commence a new time period for giving the timely notice described above. Such stockholder’s notice shall set forth:

(i) As to each person whom such stockholder proposes to nominate for election or reelection as a director, (x) all information relating to such person that is required to be disclosed in solicitations of proxies for election of directors, or is otherwise required, in each case pursuant to Regulation 14A under the Securities Exchange Act of 1934, as amended (including such person’s written consent to being named in the proxy statement as a nominee and to serving as a director if elected, and (y) a representation that such a person shall also provide any other information reasonably requested by the Corporation within 10 business days after such request); and

(ii) As to the stockholder giving the notice (x) the name and address, as they appear on the Corporation’s books, of such stockholder, and (y) the class and number of shares of the Corporation’s voting capital stock that are beneficially owned by such stockholder.

At the request of the Board of Directors, any person nominated by the Board of Directors for election as a director shall furnish to the Secretary of the Corporation that information required to be set forth in a stockholder’s notice of nomination which pertains to the nominee.

No person shall be eligible for election as a director of the Corporation unless nominated in accordance with the provisions of this Section 13, and, if the stockholder desires or requests access to the Corporation’s Proxy Statement with respect to the election of a director, Article III, Section 14 of these Bylaws.

9

The officer of the Corporation or other person presiding at the meeting shall, if the facts so warrant, determine that a nomination was not made in accordance with such provisions and, if he or she should so determine, he or she shall so declare to the meeting and the defective nomination shall be disregarded.

Section 14. Stockholder Access to Corporation’s Proxy Statement.

(a) Whenever the Corporation solicits proxies with respect to an election of directors at an annual meeting (an “Election”), it shall include in its proxy statement and on its proxy card, in addition to individuals nominated by the Board of Directors, up to the Permitted Number of individuals nominated in compliance with these Bylaws by one or more Eligible Stockholders. Any Eligible Stockholder seeking to have its nominee included in the Corporation’s proxy statement and on the Corporation’s proxy card shall comply with all provisions of these Bylaws otherwise applicable to shareholder nominations and furnish to the Secretary of the Corporation, no later than the last day on which stockholder nominations for consideration in the Election may be made under Article III, Section 13.2 of these Bylaws (the “Advance Notice Date”),

(i) the information set forth in Sections 13.2 of these Bylaws,

(ii) the written undertakings described in subsections (d) and (e) below, and

(iii) any accompanying statement from the Eligible Stockholder to be included in the Corporation’s proxy statement, which statement in order to be so included shall not exceed 500 words and must fully comply with Section 14 of the Exchange Act and the rules and regulations promulgated thereunder, including without limitation Rule 14a-9.

(b) For purposes of this Section:

(i) The “Permitted Number” means one seat on the Corporation’s Board of Directors to be filled in the Election; provided, however, that the Permitted Number shall be reduced, but not below zero, by the sum of (i) number of such director candidates for which the Corporation shall have received from Eligible Stockholders by the Advance Notice Date one or more valid stockholder notices nominating director candidates, and (ii) the number of directors in office and serving in the class of directors to be considered at the Election for whom access to the Corporation’s proxy materials was provided pursuant to this Section (“Access Director”), other than any who has served as a director continuously for at least six years. In no event will the number of nominees nominated by an Eligible Stockholder for which access to the Corporation’s proxy materials may be provided in the Election plus the number of Access Directors serving on the Board at the time of the Election exceed 25% of the total number of directors that shall constitute the whole board.

10

(ii) An “Eligible Stockholder” means a stockholder of the Corporation that, together with its Affiliates, has continuously held Beneficial Ownership and Economic Interest of not less than the Required Interest for at least one year preceding the Advance Notice Date, and that complies with all applicable provisions of these Bylaws.

One of our subsidiaries, El Dorado Chemical Company is party to an agreement with Bank of America, N.A. to sell our accounts receivables generated from product sales to a certain customer. We agreed to enter into this agreement as a courtesy to this customer. The term of this agreement matures in August 2015, with renewal options, but either party has an option to terminate the agreement pursuant to the terms of the agreement. In addition, we amended our sales agreement with the customer to offer extended payment terms under the condition that they pay an extended payment terms premium equal to the discount taken by the Bank when the accounts receivables are sold. Thus, there is no gain or loss from the sale of these receivables to the Bank. We have no continuing involvement or risks associated with the transferred accounts receivable. Pursuant to the terms of the agreement, EDC is to receive payment from the Bank no later than one business day after the Bank’s acceptance of EDC’s offer to sell the accounts receivables. As of March 31, 2015, EDC has been paid by the Bank for the accounts receivables sold to the Bank. We account for these transfers as sales under ASC 860 – Transfers and Servicing.

Summary of Significant Accounting Policies (Policies)

Accounting Policies [Abstract]

Basis of Consolidation and Presentation

Basis of Consolidation and Presentation - LSB Industries, Inc. (“LSB”) and its subsidiaries (the “Company”, “We”, “Us”, or “Our”) are consolidated in the accompanying condensed 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 are 20% to 50% owned and for which we have significant influence are accounted for on the equity method. All material intercompany accounts and transactions have been eliminated.

In the opinion of management, the unaudited condensed consolidated financial statements of the Company as of March 31, 2015 and for the three-month periods ended March 31, 2015 and 2014 include all adjustments and accruals, consisting of normal, recurring accrual adjustments which are necessary for a fair presentation of the results for the interim periods. These interim results are not necessarily indicative of results for a full year due, in part, to the seasonality of our sales of agricultural products and the timing of performing our major plant maintenance activities. Our 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.

Certain information and footnote disclosures normally included in financial statements prepared in accordance with United States (“U.S.”) generally accepted accounting principles (“GAAP”) have been condensed or omitted in this Form 10-Q pursuant to the rules and regulations of the SEC. These condensed consolidated financial statements should be read in connection with our audited consolidated financial statements and notes thereto included in our 2014 Form 10-K.

Use of Estimates

Use of Estimates - The preparation of condensed consolidated financial statements in conformity with 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

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

Short-Term Investments - Investments, which consist of certificates of deposit with an original maturity no more than 26 weeks, are considered short-term investments. These investments are carried at cost which approximates fair value.

Noncurrent Restricted Cash and Cash Equivalents

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 - Noncurrent restricted investments consist of investment balances that are designated by us for specific purposes relating to capital projects. The balance includes investments in certificates of deposits with an original maturity no longer than approximately 26 weeks. The investments in certificates of deposits are carried at cost, which approximates fair value.

Concentration of Credit Risks for Cash, Cash Equivalents, and Investments at Financial Institutions

Concentration of Credit Risks for Cash, Cash Equivalents, and Investments at Financial Institutions – Financial instruments relating to cash, cash equivalents, and investments (certificates of deposits) potentially subject us to concentrations of credit risk. At March 31, 2015, the total balance of these financial instruments exceeded the FDIC-insured limits by approximately $49.0 million. All of these financial instruments were held by financial institutions within the U.S.

Recognition of Insurance Recoveries

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.

Recently Issued Accounting Pronouncements

Recently Issued Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board issued Accounting Standard Update 2014-09-Revenue from Contracts with Customers, which will supersede nearly all existing revenue recognition guidance under GAAP. The standard’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. The original effective date for us of this standard is January 1, 2017. However, the FASB has proposed a one-year deferral of the effective date to January 1, 2018 with the option to early adopt using the original effective date. The standard 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.

For a complete discussion of our significant accounting policies, refer to the notes to our audited consolidated financial statements included in our Form 10-K for the year ended December 31, 2014 (“2014 Form 10-K”), filed with the Securities and Exchange Commission (“SEC”) on February 27, 2015.

Accrued Warranty Costs

Note 6: 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.

Commitments and Contingencies

Note 9: Commitments and Contingencies

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 with an annual minimum of 240,000 tons of industrial grade AN produced at our El Dorado Facility. The agreement included a provision for Orica to pay for product not taken. The agreement also included 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.

Planned Capital Additions – A subsidiary of EDC is party to various agreements with Leidos Constructors, LLC and others to engineer, procure and construct an ammonia plant and certain support facilities. The estimated cost for this project ranges from $275 million to $300 million, of which $172 million has been incurred and capitalized at March 31, 2015.

EDC is party to an agreement with Weatherly Inc. for the licensing, engineering, and procurement of major manufacturing equipment for a new 65% strength nitric acid plant to be constructed at our El Dorado Facility. EDC is also party to various agreements with Leidos Constructors, LLC and others to engineer, procure and construct the Nitric Acid Plant, a nitric acid concentrator and certain support facilities at the El Dorado Facility. The estimated cost for this project ranges from $125 million to $130 million, of which $105 million has been incurred and capitalized at March 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. In particular, the manufacture, production and distribution of products by our Chemical Business are activities that entail environmental and public health risks and impose obligations under the Environmental Laws and the Health Laws, many of which provide for certain performance obligations, substantial fines and criminal sanctions for violations. There can be no assurance that we will not incur material costs or liabilities in complying with such laws or in paying fines or penalties for violation of such laws. The Environmental Laws and Health Laws and enforcement policies thereunder have in the past resulted, and could in the future result, in significant compliance expenses, cleanup costs (for our sites or third-party sites where our wastes were disposed of), penalties or other liabilities relating to the handling, manufacture, use, emission, discharge or disposal of hazardous or toxic materials at or from our facilities or the use or disposal of certain of its chemical products. Historically, significant expenditures have been incurred by subsidiaries within our Chemical Business in order to comply with the Environmental Laws and Health Laws and are reasonably expected to be incurred in the future. We will also be obligated to manage certain discharge water outlets and monitor groundwater contaminants at our Chemical Business facilities should we discontinue the operations of a facility. We do not operate the natural gas wells where we own a working interest and compliance with Environmental Laws and Health Laws is controlled by others, with our Chemical Business being responsible for its proportionate share of the costs involved. As of March 31, 2015, our accrued liabilities for environmental matters totaled $514,000 relating primarily to matters discussed below. It is reasonably possible that a change in the estimate of our liability could occur in the near term. Also see discussion in Note 7 - Asset Retirement Obligations.

1. Discharge Water Matters

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

The El Dorado Facility is subject to a state National Pollutant Discharge Elimination System discharge water permit issued by the Arkansas Department of Environmental Quality. 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 limits, but has, from time to time, had difficulty demonstrating consistent compliance with the more restrictive dissolved minerals permit levels We do not believe this matter regarding meeting the permit requirements as to the dissolved minerals is a continuing issue 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.

During 2012, EDC paid a penalty of $100,000 to settle an Administrative Complaint issued by the EPA, and thereafter handled by the United States Department of Justice, relating to certain alleged violations of EDC’s 2004 NPDES permit for alleged violations through 2010. The DOJ advised that some action would 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 March 31, 2015.

In addition, the El Dorado Facility is currently operating under a consent administrative order 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. 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 March 31, 2015, in connection with this matter.

2. Air Matters

One of our subsidiaries, PCC, within our Chemical Business, has been advised that the Oklahoma Department of Environmental Quality is conducting an investigation into whether the chemical production facility located in Pryor, Oklahoma was in compliance with certain rules and regulations of the ODEQ and whether PCC’s reports of certain air emissions relating primarily to 2011 were intentionally reported incorrectly to the ODEQ. PCC has cooperated with the ODEQ in connection with this investigation. As of March 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 May 2014, the EPA conducted a Risk Management inspection of our Cherokee Facility. During October 2014, our Cherokee Facility received a notice of violation from the EPA as a result of the inspection listing eleven alleged violations. Our Cherokee Facility has had numerous conference calls and provided the EPA with written responses. During a March 2015 conference call with the EPA, the EPA provided our Cherokee Facility with some preliminary penalties as a result of the alleged violations. We anticipate receiving a formal notice of violation during 2015 from the EPA, which notice will state the amount of the penalty that the EPA will assert against the Cherokee Facility. As a result, we have accrued an estimated amount for penalties of approximately $112,000, 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 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.

The successor of a prior owner of the Hallowell Facility 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 Environmental Quality, subject to reallocation.

Our subsidiary and Chevron are pursuing with the state of Kansas, including the Kansas Department of Health and Environmental, a corrective action strategy relating to the Hallowell Facility. This strategy currently includes a long-term surface and groundwater monitoring to track the natural decline in contamination. During December 2014, the KDHE approved a corrective action study work plan, and the KDHE is to consider and recommend restoration or replacement pursuant to the work plan and/or whether to seek compensation. The KDHE will consider the recommendations in its evaluation. Currently, it is unknown what remediation and damages the KDHE would require, if any, but we believe that certain remediation activities will be required to begin during 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, which study is not scheduled to be completed until the end of 2015. We have been advised by our consultant that until the study has been completed there are too many unknowns to have a meaningful and reliable estimate as to the cost of the remediation. We have accrued for 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 relating to the study during 2015, our estimated accrual will be refined.

B. Other Pending, Threatened or Settled Litigation

In 2013, an explosion and fire occurred at the West Fertilizer Co. located in West, Texas, causing death, bodily injury and substantial property damage. West Fertilizer is not owned or controlled by us, but West Fertilizer had been a customer of EDC, purchasing AN from EDC from time to time. LSB and EDC previously received letters from counsel purporting to represent subrogated insurance carriers, personal injury claimants and persons who suffered property damages informing them that their clients are conducting investigations into the cause of the explosion and fire to determine, among other things, whether AN manufactured by EDC and supplied to West Fertilizer was stored at West Fertilizer at the time of the explosion and, if so, whether such AN may have been one of the contributing factors of the explosion. Other manufacturers of AN also supplied AN to West Fertilizer. Initially, the lawsuits that had been filed named West Fertilizer and another supplier of AN as defendants. There have been certain responses to discovery in connection with the pending lawsuits that possibly some of the AN products at West Fertilizer at the time of the explosion may have been produced by EDC. 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. Plaintiffs are alleging, 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 has retained a firm specializing in cause and origin investigations, with particular experience with fertilizer facilities, to assist EDC in its own investigation. LSB and EDC have placed its liability insurance carrier on notice, 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. Our legal counsel in this matter has represented to us that while it is extremely early in this litigation, they believe our chances of ultimately confirming the merits of EDC’s legal position are probable. However, if there is an adverse outcome in this matter as to EDC, we are unable to estimate a possible range of loss at this time. As of March 31, 2015, no liability has been established in connection with this matter, but we have incurred professional fees up to our self-insured retention amount.

We are also involved in various other claims and legal actions including claims for damages resulting from water leaks related to our Climate Control products and other product liability occurrences. Most of the product liability claims are covered by our general liability insurance, which generally includes a deductible of $250,000 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 up to the applicable deductible. At March 31, 2015, our accrued general liability insurance claims were $576,000 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.

Asset Retirement Obligation Disclosure [Abstract]

Asset Retirement Obligations

Note 7: Asset Retirement Obligations

Currently, we have various legal requirements related to operations of 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 asset retirement obligations. In addition, we currently have no plans to discontinue the use of these facilities, and the remaining life of the facilities is indeterminable. As a result, a liability for only a minimal amount relating to AROs associated with these facilities has been established. However, we will continue to review these obligations and record a liability when a reasonable estimate of the fair value can be made. In addition, our Chemical Business owns working interests in certain natural gas properties. We recognized AROs associated with the obligation to plug and abandon wells when the natural gas reserves in the wells are depleted. At March 31, 2015 and December 31, 2014, our accrued liability for AROs was $368,000 and $340,000, respectively.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivatives, Hedges, Financial Instruments and Carbon Credits

Note 10: Derivatives, Hedges, Financial Instruments and Carbon Credits

Periodically, we have three classes of contracts that are accounted for on a fair value basis, which are commodities futures/forward contracts (“commodities contracts”), foreign exchange contracts and interest rate contracts as discussed below. All of these contracts are used as economic hedges for risk management purposes but are not designated as hedging instruments. In addition as discussed below, we are issued climate reserve tonnes (“carbon credits”), of which a certain portion of the carbon credits are to be sold and the proceeds given to Bayer. The assets for carbon credits are accounted for on a fair value basis as discussed below. Also, the contractual obligations to give the related proceeds to Bayer are accounted for on a fair value basis (as discussed below) unless we enter into a firm sales commitment to sell the carbon credits. 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 March 31, 2015, the valuations of contracts classified as Level 2 related to certain futures/forward natural gas contracts, a foreign exchange contract and an interest rate swap contract.

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 March 31, 2015, the valuation inputs included the contractual weighted-average cost of $3.09 per MMBtu and the estimated weighted-average market value of $2.73 per MMBtu.

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 1.27 and the total estimated market exchange rate of 1.07 (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 March 31, 2015, the valuation inputs included the contractual weighted-average pay rate of 3.23% and the estimated market weighted-average receive rate of 0.44%. 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 March 31, 2015 and December 31, 2014, the valuations ($2.50 per carbon credit, for both periods) 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 and 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 March 31, 2015, our futures/forward copper contracts include 1,950,000 pounds of copper and extend through December 2015 at a weighted-average cost of $2.96 per pound. At December 31, 2014, our futures/forward copper contracts include 1,750,000 pounds of copper, extend through May 2015 at a weighted-average cost of $2.98 per pound. At March 31, 2015, our futures/forward natural gas contracts (accounted for on a mark-to-market basis) include approximately 6,406,000 MMBtu of natural gas and extend through June 2016 (includes contractual costs indexed to future NYMEX prices) at a weighted-average cost of $3.09 per MMBtu. At December 31, 2014, our futures/forward natural gas contracts include 8,279,000 MMBtu of natural gas and extend through June 2016 at a weighted-average cost of $3.24 per MMBtu. At March 31, 2015, our futures/forward platinum contracts include 3,000 ounces of platinum and extend through July 2015 at a weighted-average cost of $1,120.87 per ounce. At December 31, 2014, our futures/forward platinum contracts include 3,000 ounces of platinum and extend 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 March 31, 2015, our foreign exchange contract was for the receipt of approximately 648,000 Euros through May 2015 at the contractual exchange rate of 1.27 (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 the three months ended March 31, 2015 and 2014, 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 performed at the Baytown Facility. Pursuant to the terms of the agreement with Bayer, a certain portion of the carbon credits are to be used to recover the costs of the Project, and any balance thereafter to be allocated between Bayer and EDN. We have no obligation to reimburse Bayer for their costs associated with the Project, except through the transfer or sale of the carbon credits when such credits are issued to us. The assets for carbon credits are accounted for on a fair value basis and the contractual obligations associated with these carbon credits are also accounted for on a fair value basis (unless we enter into a sales commitment to sell the carbon credits). At March 31, 2015 and December 31, 2014, we had approximately 1,086,000 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.

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

At March 31, 2015 and December 31, 2014, we did not have any financial instruments with fair values significantly different from their carrying amounts, except for the Senior Secured Notes. At March 31, 2015 and December 31, 2014, the estimated fair value of the Senior Secured Notes exceeded the carrying value by approximately $17 million based on a quoted price of 104.0. These valuations are 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 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 7 - Asset Retirement Obligations.

Subsequent Event

Note 15: Subsequent Event

On April 30, 2015, a class action lawsuit was filed against our subsidiary, ClimateMaster, Inc. (“CM”), in the case styled Emmert, et al. v. ClimateMaster, Inc., in the United States District Court, Western District of Oklahoma. CM is a subsidiary within our Climate Control Business. The lawsuit alleges that a manufacturing defect in the air conditioning and heat pump equipment manufactured by CM has caused failures in certain valves used in such equipment resulting in damages sustained by consumers and the contractors, and further alleges that CM sold the equipment despite knowing of these defects. The plaintiffs are alleging that there are more than 100 class members and that the aggregate amount in controversy exceeds $5 million, exclusive of interest and costs. Plaintiffs seek actual and punitive damages, together with recovery of certain expenses. Because we have just been notified of this lawsuit, we have not had an opportunity to investigate the claims contained therein, but intend to vigorously defend this matter. We are also investigating whether such claims come within our insurance coverage, and, as of the date hereof, have not determined if the claims alleged in the lawsuit are covered under our insurance policy.
