Commitments and Contingencies

Note 9: Commitments and Contingencies

Capital Project Commitment—During November 2012, EDC entered into an agreement with Weatherly Inc. for the licensing, engineering, and procurement of major manufacturing equipment for a new 65% strength nitric acid plant to be constructed at the El Dorado Facility. In addition, EDC plans to construct a separate nitric acid concentrator. The estimated cost for this project is approximately $120 million, of which $18.6 million has been incurred and capitalized at March 31, 2013.

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

A. Environmental Matters

Our operations are subject to numerous environmental laws (“Environmental Laws”) and to other federal, state and local laws regarding health and safety matters (“Health Laws”). In particular, the manufacture, production and distribution of products by our Chemical Business are activities that entail environmental 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 relating to our Chemical Business have in the past resulted, and could in the future result, in compliance expenses, cleanup costs, penalties or other liabilities relating to the handling, manufacture, use, emission, discharge or disposal of effluents at or from our facilities or the use or disposal of certain of its chemical products. Historically, significant expenditures have been incurred by subsidiaries within our Chemical Business in order to comply with the Environmental Laws and Health Laws and are reasonably expected to be incurred in the future. We will also be obligated to manage certain discharge water outlets and monitor groundwater contaminants at our Chemical Business facilities should we discontinue the operations of a facility. We do not operate the natural gas wells where we own an interest and compliance with environmental laws is controlled by others, with our Chemical Business being responsible for its proportionate share of the costs involved. As of March 31, 2013, our accrued liabilities for environmental matters totalled $587,000 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 (“EPA”), subject to oversight by the EPA. These permits limit the type and amount of effluents that can be discharged and controls the method of such discharge. We believe that all of our chemical facilities are in compliance with the respective permits, except as discussed below.

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

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

During 2012, EDC settled an Administrative Complaint issued by the EPA, and thereafter handled by the United States Department of Justice (“DOJ”), relating to certain alleged violations of EDC’s 2004 NPDES permit. Initially the Administrative Complaint sought a penalty of $124,000 for alleged violations through December 31, 2010, but was settled by EDC for $100,000 and the EPA/DOJ indicated that any alleged violations from and after January 1, 2011, would be addressed at a later date. Thereafter, the DOJ advised that some action would be taken for alleged violations occurring after December 31, 2010. As of the date of this report, nothing has been filed by the DOJ. The cost (or range of costs) cannot currently be reasonably estimated regarding this matter. Therefore, no liability has been established at March 31, 2013.

The City of El Dorado, Arkansas (the “City”) is constructing a pipeline for disposal of wastewater generated by the City and by certain companies in the El Dorado area. EDC and other companies in the El Dorado area have entered into a funding agreement and operating agreement with the City, pursuant to which each party has agreed to contribute to the cost of construction and the annual operating costs of the pipeline for the right to use the pipeline to dispose its wastewater. EDC is funding a portion of the construction of the pipeline that will be owned by the City because it believes that it will enable EDC to comply with water discharge permit limits under current and foreseeable regulations. EDC anticipates its share of the funding for the capital cost in connection with the construction of the pipeline will be approximately $3.7 million, of which most of these costs have been incurred and capitalized as of March 31, 2013. The City plans to complete the construction of the pipeline in 2013. Once the pipeline is completed, EDC’s estimated share of the annual operating costs is to be $100,000 to $150,000. The initial term of the operating agreement is through December 2053. Although construction of the pipeline is nearly complete, a group opposing the City’s construction of the pipeline has sued the Corps of Engineers for issuing the permit to the City to construct and operate the pipeline.

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

2. Air Matters

The EPA has sent information requests to most, if not all, of the operators of nitric acid plants in the United States, including our El Dorado and Cherokee Facilities and the nitric acid plant (“Baytown Facility”) operated by our subsidiary, EDN, under Section 114 of the Clean Air Act as to construction and modification activities at each of these facilities over a period of years. These information requests were to enable the EPA to determine whether these facilities are in compliance with certain provisions of the Clean Air Act. If the EPA were successful in establishing that any of our chemical facilities were in violation of the Clean Air Act, the EPA could assess civil penalties of up to $27,500 per day and require the facility to retrofit with the “best available control technology.”

After a review by our Chemical Business of these facilities in obtaining information for the EPA pursuant to the EPA’s request, our Chemical Business management believes that certain facilities within our Chemical Business will be required to make capital improvements to emission equipment in order to comply with the requirements of the Clean Air Act. Our Chemical Business has been in negotiations with the EPA and has proposed a global settlement in connection with this matter. A settlement offer would require implementation of additional pollution controls to be installed over a period of time in each of our eight affected nitric acid plants to achieve certain proposed emission rates, two of which are already complete. The proposal also offered to include a modest civil penalty but did not provide an amount of any proposed civil penalty. The estimated capital cost to achieve the proposed emission rates is $2 million to $3 million per plant for the remaining six plants, and these capital investments are proposed to be made over a period of several years.

The DOJ, on behalf of the EPA, has responded in writing to our proposed global settlement offer and advised in its response which of our proposals are acceptable and not acceptable and certain other provisions that the United States would require in a global settlement. The DOJ’s response also provided that it will require, among other things, that we pay an appropriate civil penalty to the United States and participating state parties, with the amount to be determined after the parties have reached agreement on the core components of a consent decree, and that any settlement is contingent upon the incorporation of the settlement terms into a definitive consent decree acceptable to the parties. Therefore a liability for potential civil penalties has been established in connection with this matter and is included in our accrued liabilities for environmental matters discussed above. We are currently corresponding with the DOJ in an effort to resolve this matter.

One of our subsidiaries, Pryor Chemical Company (“PCC”), within our Chemical Business, has been advised that the Oklahoma Department of Environmental Quality (“ODEQ”) is conducting an investigation into whether the chemical production facility located in Pryor, Oklahoma (the “Pryor Facility”) was in compliance with certain rules and regulations of the ODEQ and whether the Pryor Facility’s reports of certain air emissions relating primarily to 2011 were intentionally reported incorrectly to the ODEQ. Pursuant to the request of the ODEQ, PCC has submitted information and a report to the ODEQ as to the reports filed by the Pryor Facility relating to the air emissions in question and has and continues to cooperate with the ODEQ in connection with this investigation. However, on February 20, 2013, investigators with the ODEQ obtained documents from the Pryor Facility in connection with this investigation pursuant to a search warrant and interviewed several employees at the facility. Each of the Company and PCC has received a subpoena, upon the application of the Attorney General of the State of Oklahoma, for documents relating to this matter. The Oklahoma Attorney General’s office subsequently confirmed that neither LSB nor PCC are obligated to respond to the subpoenas and that the subpoenas have been terminated; however, the investigation is ongoing. As of the date of this report, we are not aware of any recommendations made or to be made by the ODEQ with respect to formal legal action to be taken or recommended as a result of the ongoing investigation. Therefore, no liability has been established at March 31, 2013 in connection with this matter.

3. Other Environmental Matters

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

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

Our subsidiary and Chevron are pursuing with the state of Kansas a course of long-term surface and groundwater monitoring to track the natural decline in contamination. Currently, our subsidiary and Chevron are in the process of performing additional surface and groundwater testing. We have accrued for our allocable portion of costs for the additional testing, monitoring and risk assessments that could be reasonably estimated.

In addition, the Kansas Department of Health and Environment (“KDHE”) notified our subsidiary and Chevron that the Hallowell Facility has been referred to the KDHE’s Natural Resources Trustee, who is to consider and recommend restoration, replacement and/or whether to seek compensation. KDHE will consider the recommendations in its evaluation. Currently, it is unknown what damages the KDHE would claim, if any. The ultimate required remediation, if any, is unknown. The nature and extent of a portion of the requirements are not currently defined, and the associated costs (or range of costs) are not currently reasonably estimable.

Our allocable portion of the total estimated liability related to the Hallowell Facility has been established in connection with this matter and is included in our accrued liabilities for environmental matters discussed above. The estimated amount is not discounted to its present value.

B. Other Pending, Threatened or Settled Litigation

Other Claims and Legal Actions

We are also involved in various other claims and legal actions including claims for damages resulting from water leaks related to our Climate Control products and other product liability occurrences. Most of the product liability claims are covered by our general liability insurance, which generally includes a deductible of $250,000 per claim. For any claims or legal actions that we have assessed the likelihood of our liability as probable, we have recognized our estimated liability up to the applicable deductible. At March 31, 2013, our accrued general liability insurance claims were $647,000 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 or results of operations.

Summary of Significant Accounting Policies (Policies)	3 Months Ended
Summary of Significant Accounting Policies (Policies)	Mar. 31, 2013
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 geothermal and water source heat pumps and air handling products (the “Climate Control Business”). LSB is a holding company with no significant operations or assets other than cash, cash equivalents, and investments in its subsidiaries. Our Chemical Business’ ownership of working interests in natural gas properties is accounted for as an undivided interest, whereby we reflect our proportionate share of the underlying assets, liabilities, revenues and expenses. 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, 2013 and for the three month periods ended March 31, 2013 and 2012 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, certain downtime events associated with our chemical facilities, 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 2012 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.
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.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements—The Financial Accounting Standards Board (“FASB”) issued accounting standard updates (“ASU”) requiring additional disclosures about an entity’s offsetting (netting) of certain assets and liabilities for the purpose of improving the transparency of financial reporting. Entities are required to disclose both gross information and net information about certain instruments and transactions eligible for offset in the balance sheet and certain instruments and transactions subject to an agreement similar to a master netting arrangement. The new disclosure requirements become effective for us on January 1, 2013 and are to be applied retrospectively. The adoption of these ASUs did not impact our disclosures to the accompanying financial statements.

- Definition

Disclosure of accounting policy regarding (1) the principles it follows in consolidating or combining the separate financial statements, including the principles followed in determining the inclusion or exclusion of subsidiaries or other entities in the consolidated or combined financial statements and (2) its treatment of interests (for example, common stock, a partnership interest or other means of exerting influence) in other entities, for example consolidation or use of the equity or cost methods of accounting. The accounting policy may also address the accounting treatment for intercompany accounts and transactions, noncontrolling interest, and the income statement treatment in consolidation for issuances of stock by a subsidiary.

Property and Business Interruption Insurance Claims and Recoveries

Note 12: Property and Business Interruption Insurance Claims and Recoveries

Pryor Facility

Beginning on February 27, 2012, the Pryor Facility experienced downtime in the urea plant due to a damaged stainless steel liner within the urea reactor. As a result, the Pryor Facility was unable to produce urea ammonium nitrate (“UAN”) through early July 2012. Our insurance policy provides, for the policy period covering this claim, for repair or replacement cost coverage relating to property damage with a $1.0 million deductible and provides for business interruption coverage for certain lost profits and extra expense with a 30-day waiting period. A notice of insurance claims for property damage and business interruption was filed with the insurance carriers. After an initial investigation was performed by an insurance adjuster, we received a reservation of rights letter stating that some insurance policy exclusions could apply resulting in a full or partial denial as to our claims for property damage and/or business interruption. See additional information in Note 16-Subsequent Events.

El Dorado Facility

On May 15, 2012, the El Dorado Facility suffered significant damage when a reactor in its 98% strength nitric acid plant (“DSN plant”) exploded. No employees or individuals in the surrounding area were seriously injured as a result of the explosion. In addition, several other plants and infrastructure within the El Dorado Facility sustained various degrees of damage. Our insurance policy provides, for the policy period covering this claim, for repair or replacement cost coverage relating to property damage with a $1.0 million deductible and provides for business interruption coverage for certain lost profits and extra expense with a 30-day waiting period. A notice of insurance claims for property damage and business interruption was filed with the insurance carriers, but the total amounts have not been determined. The engineering firm representing our insurance carriers has determined that the DSN plant was not destroyed by the explosion and was repairable. However, we have concluded that due to the extensive damage, the DSN plant should not be repaired but should be replaced with a new 65% strength nitric acid plant and a separate nitric acid concentrator. The total amount of insurance recoveries relating to this event will be dependent on an estimate of the costs and the length of time to repair the damaged DSN plant as if it would have been repaired. The estimated cost to repair the DSN plant ranges from $48 million to $60 million but the length of time to repair has not yet been determined.

Based upon our assessment that it was probable that the amount of coverage for property damages would exceed our property loss deductible, the net book value of the damaged property and other recoverable costs incurred through March 31, 2013, we recorded an insurance claim receivable relating to this event, which offset the loss on the disposal of the damaged property and certain repairs and clean-up costs incurred (“recoverable costs”).

During 2012, our insurance carriers approved unallocated payments totaling $40 million (of which $20 million was paid in 2012 and $20 million was paid in January 2013). We received correspondence associated with the $20 million received in January 2013, which stated that our insurance carriers are still investigating the circumstances surrounding this event (including the cause of this event, scope of our losses and support for our claim) under a reservation of rights. For financial reporting purposes, we allocated $28.6 million to our property insurance claim and $11.4 million to our business interruption claim primarily based on the claims information provided to our insurance carriers as of that time in relation to our requests for insurance proceeds.

The $28.6 million allocated to the property insurance claim was partially applied against the recoverable costs totaling $22.4 million. The insurance recovery in excess of the recoverable costs of $6.2 million was deferred (included in current liabilities at March 31, 2013) since it is considered a gain contingency. The deferred portion of this recovery, and any additional recoveries, will be recognized if, and when, realized or realizable and earned.

The insurance recovery of $11.4 million allocated to the business interruption claim was applied against recoverable costs (primarily relating to additional expenses associated with purchased product sold to our customers while certain of our nitric and sulfuric acid plants were being repaired) totaling $8.0 million as a reduction to cost of sales ($7.3 million during the fourth quarter of 2012 and $0.7 million during the first quarter of 2013). The insurance recovery in excess of recoverable costs of $3.4 million was deferred (included in current liabilities at March 31, 2013) since a portion of this amount relates to recoverable costs, which we were unable to conclude that it was at least probable (for financial reporting purposes) that these costs would be approved and a portion of this amount relates to lost profits, which is considered a gain contingency. The deferred portion of this recovery, and any additional recoveries, will be recognized if, and when, realized or realizable and earned.

As of March 31, 2013, there was no insurance claim receivable balance relating to this event.

Cherokee Facility

On November 13, 2012, a pipe ruptured within the Cherokee Facility causing damage primarily to the heat exchanger portion of its ammonia plant. No serious injuries or environmental impact resulted from the pipe rupture. As a result of the damage, the Cherokee Facility can only produce, on a limited basis, nitric acid and ammonium nitrate (“AN”) solution from purchased ammonia until the repairs are completed (See Note 16 – Subsequent Events). Our insurance policy provides, for the policy period covering this claim, for repair or replacement cost coverage relating to property damage with a $2.5 million deductible and provides for business interruption coverage for certain lost profits and extra expense with a 30-day waiting period. A notice of insurance claims for property damage and business interruption was filed with the insurance carriers, but the total amounts have not been determined but are expected to be substantial.

In March 2013, our insurance carriers approved payments relating to our business interruption claim totaling $15 million. Also see Note 16—Subsequent Events. We received correspondence associated with the approval, which stated that our insurance carriers are still investigating the circumstances surrounding this event (including the cause of this event, scope of our losses and support for our claim) under a reservation of rights.

The business interruption insurance recovery of $15 million was applied against recoverable costs (primarily relating to additional expenses associated with purchased product sold or used in products sold to our customers while our facility is being repaired) totaling $10.1 million as a reduction to cost of sales (see Note 16—Subsequent Events). The insurance recovery in excess of recoverable costs of $4.9 million was not recognized since a portion of this amount relates to recoverable costs, which we were unable to conclude that it was at least probable (for financial reporting purposes) that these costs would be approved and a portion of this amount relates to lost profits, which is considered a gain contingency. The unrecognized portion of this recovery, and any additional recoveries, will be recognized if, and when, realized or realizable and earned.

As of March 31, 2013, the balance of the insurance claim receivable relating to this event was $12.1 million, consisting of the recognized portion of the approved payments due from our insurance carriers discussed above and recoverable costs associated with our property insurance claim.

It is possible that the actual development of the insurance claims discussed above could be different from our current allocations and estimates.

Asset Retirement Obligations

Asset Retirement Obligations

Note 7: Asset Retirement Obligations Currently, we have an obligation to plug and abandon a wastewater injection well at one of our Chemical Business facilities when the permit expires. We are also contractually obligated through at least December 2053 to pay a portion of the operating costs of a municipally owned wastewater pipeline currently being constructed that will serve our chemical production facility located in El Dorado, Arkansas (the “El Dorado Facility”). 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 (“ARO”). 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, 2013 and December 31, 2012, our accrued liability for AROs was $161,000 and $154,000, respectively.

(A)

Our wholly owned subsidiary, ThermaClime, LLC (“ThermaClime”) and its subsidiaries (collectively, the “Borrowers”) are parties to a $50 million revolving credit facility, as amended (the “Working Capital Revolver Loan”). The Working Capital Revolver Loan provides for advances based on specified percentages of eligible accounts receivable and inventories for ThermaClime and its subsidiaries. The Working Capital Revolver Loan matures on March 29, 2016, but could be extended to April 13, 2017, under certain conditions. The Working Capital Revolver Loan accrues interest at a base rate (generally equivalent to the prime rate) plus 0.50% if borrowing availability is greater than $25 million, otherwise plus 0.75% or, at our option, accrues interest at LIBOR plus 1.50% if borrowing availability is greater than $25 million, otherwise plus 1.75%. At March 31, 2013, the interest rate was 3.75% based on LIBOR. Interest is paid monthly, if applicable. As of March 31, 2013, the amount available for borrowing under the Working Capital Revolver Loan was approximately $48.4 million.

The Working Capital Revolver Loan is secured by the assets of all the ThermaClime entities other than El Dorado Nitric Company and its subsidiaries (“EDN”), but excluding the assets securing the Secured Term Loan, certain production equipment and facilities utilized by the Climate Control Business, and certain distribution-related assets of EDC. In addition, EDN is neither a borrower under, nor guarantor of, the Working Capital Revolver Loan. At March 31, 2013, the carrying value of the pledged assets was approximately $217 million. The Working Capital Revolver Loan also contains numerous covenants.

(B)

ThermaClime and certain of its subsidiaries are parties to a term loan agreement (the “Secured Term Loan”). The Secured Term Loan matures on March 29, 2016. The Secured Term Loan requires quarterly principal payments of approximately $0.9 million, plus interest and a final balloon payment of $56.3 million due on March 29, 2016. The stated interest rate on the Secured Term Loan includes a variable interest rate (based on three-month LIBOR plus 300 basis points, a rate that is adjusted quarterly) and a fixed interest rate as detailed below:


	March 31, 2013
	Stated Interest			Principal
	Rate			Balance
	(Dollars in Thousands)
Variable interest rate		3.28	%	$	45,000
Fixed interest rate		5.15	%		22,500

Weighted-average interest rate		3.91	%	$	67,500

The Secured Term Loan is secured by the real property and equipment located at our chemical production facilities located in the El Dorado Facility and in Cherokee, Alabama (the “Cherokee Facility”). The carrying value of the pledged assets is approximately $128 million at March 31, 2013. In addition, the Secured Term Loan is guaranteed by LSB.

The Secured Term Loan borrowers are also subject to numerous covenants under the agreement. At March 31, 2013, the carrying value of the restricted net assets (including pledged assets) of ThermaClime and its subsidiaries was approximately $130 million. As defined in the agreement, the Secured Term Loan borrowers are also subject to a minimum fixed charge coverage ratio of not less than 1.10 to 1 and a maximum leverage ratio of not greater than 4.50 to 1. Both of these requirements are measured quarterly on a trailing twelve-month basis. The Secured Term Loan borrowers were in compliance with these financial covenants for the twelve-month period ended March 31, 2013.

A prepayment premium equal to 1.0% of the principal amount prepaid is due to the lenders should the borrowers elect to prepay on or prior to March 29, 2014; however, this premium is eliminated thereafter.

(C)

On February 1, 2013, Zena Energy LLC (“Zena”), a subsidiary within our Chemical Business, entered into a loan (the “Secured Promissory Note”) with a lender in the original principal amount of $35 million. The Secured Promissory Note follows the acquisition by Zena of working interests (“Working Interests”) in certain natural gas properties during October 2012. The proceeds of the Secured Promissory Note effectively financed $35 million of the approximately $50 million purchase price of the Working Interests previously paid out of LSB’s working capital. The proceeds of the Secured Promissory Note are being used for general working capital purposes. The Secured Promissory Note matures on February 1, 2016. Principal and interest are payable monthly based on a five-year amortization at a defined LIBOR rate plus 300 basis points (but not below 3.00% per annum) with a final balloon payment of $15.3 million. The interest rate at March 31, 2013 was 3.28%. The loan is secured by the Working Interests and related properties and proceeds.

Summary of Significant Accounting Policies

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, 2012 (“2012 Form 10-K”), filed with the Securities and Exchange Commission (“SEC”) on February 28, 2013.

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 geothermal and water source heat pumps and air handling products (the “Climate Control Business”). LSB is a holding company with no significant operations or assets other than cash, cash equivalents, and investments in its subsidiaries. Our Chemical Business’ ownership of working interests in natural gas properties is accounted for as an undivided interest, whereby we reflect our proportionate share of the underlying assets, liabilities, revenues and expenses. 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, 2013 and for the three month periods ended March 31, 2013 and 2012 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, certain downtime events associated with our chemical facilities, 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 2012 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.

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.

Recently Issued Accounting Pronouncements—The Financial Accounting Standards Board (“FASB”) issued accounting standard updates (“ASU”) requiring additional disclosures about an entity’s offsetting (netting) of certain assets and liabilities for the purpose of improving the transparency of financial reporting. Entities are required to disclose both gross information and net information about certain instruments and transactions eligible for offset in the balance sheet and certain instruments and transactions subject to an agreement similar to a master netting arrangement. The new disclosure requirements become effective for us on January 1, 2013 and are to be applied retrospectively. The adoption of these ASUs did not impact our disclosures to the accompanying financial statements.

State		31			166

Total Deferred		340			1,337

Provision (benefit) for income taxes	$	(745	)	$	7,802

For the three months ended March 31, 2013 and 2012, the current provision (benefit) for federal income taxes shown above includes regular federal income tax after the consideration of permanent and temporary differences between income (loss) for GAAP and tax purposes, including the benefit related to the retroactive tax relief for certain tax provisions that expired in 2012 as discussed below. For the three months ended March 31, 2013 and 2012, the current provision (benefit) for state income taxes shown above includes regular state income tax and provisions for uncertain state income tax positions.

Our annual estimated effective tax rate for 2013 includes the impact of permanent tax differences, such as the domestic manufacturer’s deduction, the advanced energy credit and other permanent items. In connection with the American Taxpayer Relief Act of 2012 that was signed into law in January 2013, we recorded a one-time benefit of approximately $0.5 million related to the retroactive tax relief for certain tax provisions that expired in 2012. Because the legislation was signed into law after December 31, 2012, the retroactive effects of the law was reflected in the first quarter of 2013 and impacted the estimated effective tax rate for 2013.

The tax benefit for the three months ended March 31, 2013 was $0.7 million (38% of pre-tax loss, excluding the impact of the 2012 retroactive tax benefits) and a tax provision of $7.8 million (35% of pre-tax income) for the three months ended March 31, 2012.

LSB and certain of its subsidiaries file income tax returns in the U.S. federal jurisdiction and various state jurisdictions. With few exceptions, the 2009-2011 years remain open for all purposes of examination by the U.S. Internal Revenue Service (“IRS”) and other major tax jurisdictions. We are under examination by the IRS for the tax years 2008-2010. As of March 31, 2013, the IRS has proposed certain adjustments, which we are protesting. We anticipate that the adjustments, if any, will not result in a material change to our financial position, results of operations and cash flows.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

Derivatives, Hedges, Financial Instruments and Carbon Credits

3 Months Ended

Mar. 31, 2013

Derivatives, Hedges, Financial Instruments and Carbon Credits

Note 10: Derivatives, Hedges, Financial Instruments and Carbon Credits We have two classes of contracts that are accounted for on a fair value basis, which are commodities futures/forward contracts (“commodities 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 Material Science LLC (“Bayer”). The carbon credits are accounted for on a fair value basis as discussed below. Also the contractual obligations associated with these carbon credits 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, 2013 and December 31, 2012, the valuations of contracts classified as Level 2 related to interest rate swap contracts. For interest rate swap contracts, we utilize valuation software and market data from a third-party provider. These contracts are valued using a discounted cash flow model that calculates the present value of future cash flows pursuant to the terms of the contracts and using market information for forward interest-rate yield curves. At March 31, 2013, the valuation inputs included the contractual weighted-average pay rate of 3.23% and the estimated market weighted-average receive rate of 0.51%. No valuation input adjustments were considered necessary relating to nonperformance risk for the contracts.

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

Commodities Contracts

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

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, 2013 and 2012, no cash flows occurred relating to the purchase or sale of interest rate contracts. The cash flows associated with the interest rate swap payments are included in cash flows from continuing operating activities.

Carbon Credits and Associated Contractual Obligation

Periodically, we are issued carbon credits by the Climate Action Reserve in relation to a greenhouse gas reduction project (“Project”) performed at the Baytown Facility. Pursuant to the terms of the agreement with Bayer, a certain portion of the carbon credits are to be used to recover the costs of the Project, and any balance thereafter to be allocated between Bayer and EDN. We have no obligation to reimburse Bayer for its costs associated with the Project, except through the transfer or sale of the carbon credits when such credits are issued to us. The 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 firm sales commitment to sell the carbon credits). At March 31, 2013, we had approximately 625,000 carbon credits (a minimal amount at December 31, 2012), all of which were subject to contractual obligations. The cash flows associated with the carbon credits and the associated contractual obligations are included in cash flows from continuing investing activities, when applicable.

The following details our assets and liabilities that are measured at fair value on a recurring basis at March 31, 2013 and December 31, 2012:

At March 31, 2013 and December 31, 2012, we did not have any financial instruments with fair values significantly different from their carrying amounts. These financial instruments include our long-term debt agreements, which valuations 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 the 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.

During August 2012, El Dorado Chemical Company (“EDC”) entered into an agreement with Bank of America, N.A. (the “Bank”) to sell our accounts receivables generated from product sales to a certain customer. We agreed to enter into this agreement as a courtesy to this customer. The initial term of this agreement is for one year, 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, 2013, EDC has been paid by the Bank for the accounts receivables sold to the Bank. We account for these transfers as sales under ASC 860 – Transfers and Servicing.

- Definition

The entire disclosure for claims held for amounts due a entity, excluding financing receivables. Examples include, but are not limited to, trade accounts receivables, notes receivables, loans receivables. Includes disclosure for allowance for credit losses.

Accrued Warranty Costs

Note 6: Accrued Warranty Costs Our Climate Control Business sells equipment that has an expected life, under normal circumstances and use, that 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:
