Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	9. Commitments and Contingencies Purchase and Sales Commitments – We have the following significant purchase and sales commitments. UAN supply agreement – The Pryor Chemical Company (“PCC”) is party to an agreement with CVR. CVR has the exclusive right (but not the obligation) to purchase all the tons of UAN that are produced by PCC with certain limitations. If CVR fails to take delivery of certain tons, PCC pursuant to the terms of the agreement may immediately sell such unpurchased product to a third-party without restriction. The current term of the agreement expires in May 2020, but includes automatic renewals for one or more additional one-year terms unless terminated by either party. However, CVR may unilaterally terminate the agreement upon 180 days’ advance written notice of termination to PCC; provided, however, that each party’s rights and obligations pertaining to UAN that CVR committed to purchase before such advance notice will survive termination. Additionally, PCC can terminate the agreement upon 90 days’ advance written notice of termination to CVR; provided, however, that each party’s rights and obligations pertaining to UAN that PCC committed to sell prior to such advance notice will survive termination. Ammonia supply agreement – EDC is party to an agreement, as amended, with Koch Fertilizer under which Koch Fertilizer agrees to purchase, with minimum purchase requirements, the ammonia that (a) will be produced at the El Dorado Facility and (b) a portion that is in excess of EDC’s needs as defined. As amended, the term of the agreement expires in June 2022 but automatically continues for one or more additional one-year terms unless terminated by either party by delivering a notice of termination at least nine months prior to the end of term in effect. Covestro agreement – El Dorado Nitrogen LLC (“EDN”) and EDC, are party to an agreement (the “Covestro Agreement”) with Covestro. EDN operates the Baytown Facility located within Covestro’s chemical manufacturing complex located in Baytown, Texas. Under the terms of the Covestro Agreement, EDN is responsible for the maintenance and operation of the Baytown Facility, which facility produces all of Covestro’s requirements for nitric acid for use in Covestro’s chemical manufacturing complex. If there is a change in control of EDN, Covestro has the right to terminate the Covestro Agreement upon payment of certain fees to EDN. The Covestro Agreement expires in June 2021, with options for renewal. Natural Gas Purchase and Other Commitments – Certain of our subsidiaries are parties to contracts to purchase natural gas for anticipated production needs at certain of our facilities. Since these contracts are considered normal purchases because they provide for the purchase of natural gas that will be delivered in quantities expected to be used over a reasonable period of time in the normal course of business and are documented as such, these contracts are exempt from the accounting and reporting requirements relating to derivatives. At December 31, 2019, our natural gas contracts, which qualify as normal purchases under GAAP and thus are not mark-to-market, included volume purchase commitments with fixed costs of approximately 7.0 million MMBtus of natural gas. These contracts extend through December 2020 at a weighted-average cost of $2.23 per MMBtu ($15.7 million) and a weighted-average market value of $2.06 per MMBtu ($14.5 million). In addition, we had standby letters of credit outstanding of approximately $2.8 million at December 31, 2019. Wastewater Pipeline Operating Agreement – EDC is party to an operating agreement for the right to use a pipeline to dispose its wastewater. EDC is contractually obligated to pay a portion of the operating costs of the pipeline, which portion is estimated to be $100,000 to $150,000 annually. The initial term of the operating agreement is through December 2053. Performance and Payment Bonds – We are contingently liable to sureties in respect of certain insurance bonds issued by the sureties in connection with certain contracts entered into by certain subsidiaries in the normal course of business. These insurance bonds primarily represent guarantees of future performance of our subsidiaries. As of December 31, 2019, we have agreed to indemnify the sureties for payments, up to $10 million, made by them in respect of such bonds. All of these insurance bonds are expected to expire or be renewed in 2020. 9. Commitments and Contingencies (continued) Employment and Severance Agreements - We have employment and severance agreements with several of our officers. The agreements, as amended, provide for annual base salaries, bonuses and other benefits commonly found in such agreements. In the event of termination of employment due to a change in control (as defined in the agreements), the agreements provide for payments aggregating $8.3 million at December 31, 2019. Also see Note 14-Related Party Transactions. Settlement of a Gain Contingency - During 2018, we and a vendor mediated a settlement relating primarily to a business interruption claim caused by defective work performed by the vendor at our Pryor Facility. As a result of the settlement, the vendor paid us $4.0 million. As part of the settlement, we paid the vendor $0.5 million to settle $1.1 million of invoices that were held in our accounts payable. As a result, we recognized a recovery from this settlement totaling $4.6 million of which $4.4 million was classified as a reduction to cost of sales (primarily relating to our business interruption claim) and the remaining balance of $0.2 million as a reduction to PP&E. Legal Matters - Following is a summary of certain legal matters involving the Company: A. Environmental Matters Our facilities and operations are subject to numerous federal, state and local environmental laws and to other laws regarding health and safety matters (collectively, the “Environmental and Health Laws”), many of which provide for certain performance obligations, substantial fines and criminal sanctions for violations. Certain Environmental and Health Laws impose strict liability as well as joint and several liability for costs required to remediate and restore sites where hazardous substances, hydrocarbons or solid wastes have been stored or released. We may be required to remediate contaminated properties currently or formerly owned or operated by us or facilities of third parties that received waste generated by our operations regardless of whether such contamination resulted from the conduct of others or from consequences of our own actions that were in compliance with all applicable laws at the time those actions were taken. In addition, claims for damages to persons or property, including natural resources, may result from the environmental, health and safety effects of our operations. 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. Our insurance may not cover all environmental risks and costs or may not provide sufficient coverage if an environmental claim is made against us. The Environmental and Health Laws and related enforcement policies have in the past resulted, and could in the future result, in significant compliance expenses, cleanup costs (for our sites or third-party sites where our wastes were disposed of), penalties or other liabilities relating to the handling, manufacture, use, emission, discharge or disposal of hazardous or toxic materials at or from our facilities or the use or disposal of certain of its chemical products. Further, a number of our facilities are dependent on environmental permits to operate, the loss or modification of which could have a material adverse effect on their operations and our financial condition. Historically, significant capital expenditures have been incurred by our subsidiaries in order to comply with the Environmental and Health Laws, and significant capital expenditures are expected to be incurred in the future. We will also be obligated to manage certain discharge water outlets and monitor groundwater contaminants at our facilities should we discontinue the operations of a facility. As of December 31, 2019, our accrued liabilities for environmental matters totaled $183,000 relating primarily to the matters discussed below. It is reasonably possible that a change in the estimate of our liability could occur in the near term. Also, see discussion in Note 6 – Asset Retirement Obligations. 1. Discharge Water Matters Each of our manufacturing facilities generates process wastewater, which may include cooling tower and boiler water quality control streams, contact storm water and miscellaneous spills and leaks from process equipment. The process water discharge, storm-water runoff and miscellaneous spills and leaks are governed by various permits generally issued by the respective state environmental agencies as authorized and overseen by the U.S. Environmental Protection Agency. These permits limit the type and amount of effluents that can be discharged and control the method of such discharge. 9. Commitments and Contingencies (continued) In October 2017, PCC filed a Permit Renewal Application for its Non-Hazardous Injection Well Permit at the Pryor Facility. Although the Injection Well Permit expired in 2018, PCC continues to operate the injection well pending the Oklahoma Department of Environmental Quality (“ODEQ”) action on the Permit Renewal Application. PCC and ODEQ are engaged in ongoing discussions related to the renewal of the injection well to address the wastewater stream. Our El Dorado Facility is subject to a National Pollutant Discharge Elimination System (“NPDES”) permit issued by the Arkansas Department of Environmental Quality (“ADEQ”) in 2004. In 2010, the ADEQ issued a draft NPDES permit renewal for the El Dorado Facility, which contained more restrictive discharge limits than the previous 2004 permit. In August 2017, ADEQ issued a final NPDES permit with new dissolved mineral limits. EDC filed an appeal in September 2017 and a Permit Appeal Resolution (“PAR”) was signed in July 2018. EDC is in compliance with the revised permit limits agreed upon in the PAR. In November 2006, the El Dorado Facility entered into a Consent Administrative Order (“CAO”) that recognizes the presence of nitrate contamination in the shallow groundwater. The CAO required EDC to perform semi-annual groundwater monitoring, continue operation of a groundwater recovery system, submit a human health and ecological risk assessment, and submit a remedial action plan. The risk assessment was submitted in August 2007. In February 2015, the ADEQ stated that El Dorado Chemical was meeting the requirements of the CAO and should continue semi-annual monitoring. Subsequent to the PAR mentioned previously, a new CAO was signed in October 2018, which required an Evaluation Report of the data and effectiveness of the groundwater remedy for nitrate contamination. In February 2019, the Evaluation Report was submitted to the ADEQ and the ADEQ approved the report in August 2019. No liability has been established at December 31, 2019, in connection with this ADEQ matter. 2. Other Environmental Matters In 2002, certain of our subsidiaries sold substantially all of their operating assets relating to a Kansas chemical facility (the “Hallowell Facility”) but retained ownership of the real property where the facility is located. 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. As the successor to a prior owner of the Hallowell Facility, Chevron Environmental Management Company (“Chevron”) has agreed in writing, within certain limitations, to pay and has been paying one-half of the costs of the investigation and interim measures relating to this matter as approved by the Kansas Department of Health and Environment (the “KDHE”), subject to reallocation. Our subsidiary and Chevron have retained an environmental consultant to prepare and perform a corrective action study work plan as to the appropriate method to remediate the Hallowell Facility. The proposed strategy includes long-term surface and groundwater monitoring to track the natural decline in contamination. The KDHE is currently evaluating the corrective action strategy, and, thus, it is unknown what additional work the KDHE may require, if any, at this time. We accrued our allocable portion of costs primarily for the additional testing, monitoring and risk assessments that could be reasonably estimated, which is included in our accrued liabilities for environmental matters discussed above. The estimated amount is not discounted to its present value. As more information becomes available, our estimated accrual will be refined. B. Other Pending, Threatened or Settled Litigation In 2013, an explosion and fire occurred at the West Fertilizer Co. (“West Fertilizer”) located in West, Texas, causing death, bodily injury and substantial property damage. West Fertilizer is not owned or controlled by us, but West Fertilizer was a customer of EDC, and purchased AN from EDC from time to time. LSB and EDC received letters from counsel purporting to represent subrogated insurance carriers, personal injury claimants and persons who suffered property damages informing LSB and EDC that their clients are conducting investigations into the cause of the explosion and fire to determine, among other things, whether AN manufactured by EDC and supplied to West Fertilizer was stored at West Fertilizer at the time of the explosion and, if so, whether such AN may have been one of the contributing factors of the explosion. Initial lawsuits filed named West Fertilizer and another supplier of AN as defendants. In 2014, EDC and LSB were named as defendants, together with other AN manufacturers and brokers that arranged the transport and delivery of AN to West Fertilizer, in the case styled City of West, Texas vs. CF Industries, Inc., et al., in the District Court of McLennan County, Texas. The plaintiffs allege, among other things, that LSB and EDC were negligent in the production and marketing of fertilizer products sold to West Fertilizer, resulting in death, personal injury and property damage. EDC retained a firm specializing in cause and origin investigations with particular experience with fertilizer facilities, to assist EDC in its own investigation. LSB and EDC placed its liability insurance carrier on notice, and the carrier is handling the defense for LSB and EDC concerning this matter. 9. Commitments and Contingencies (continued) Our product liability insurance policies have aggregate limits of general liability totaling $100 million, with a self-insured retention of $250,000, which retention limit has been met relating to this matter. In August 2015, the trial court dismissed plaintiff’s negligence claims against us and EDC based on a duty to inspect but allowed the plaintiffs to proceed on claims for design defect and failure to warn. Subsequently, we and EDC have entered into confidential settlement agreements (with approval of our insurance carriers) with several plaintiffs that had claimed wrongful death and bodily injury and insurance companies asserting subrogation claims for damages from the explosion. These settlements have been paid by the insurer as of December 31, 2019. While these settlements resolve the claims of a number of the claimants in this matter for us, we continue to be party to litigation related to this explosion by other plaintiffs, in addition to indemnification or defense obligations we may have to other defendants. We continue to defend these lawsuits vigorously and we are unable to estimate a possible range of loss at this time if there is an adverse outcome in this matter as to EDC. As of December 31, 2019, no liability reserve has been established in connection with this matter. In 2015, a case styled Dennis Wilson vs. LSB Industries, Inc., et al., was filed in the United States District Court for the Southern District of New York. The plaintiff purports to represent a class of our shareholders and asserts that we violated federal securities laws by allegedly making material misstatements and omissions about delays and cost overruns at our El Dorado Chemical Company manufacturing facility and about our financial well-being and prospects. The lawsuit, which also names certain current and former officers, sought an unspecified amount of damages. In October 2018, LSB entered into a preliminary, binding term sheet to settle Dennis Wilson vs. LSB Industries, Inc., et al., which was subject to approval by the court. On January 17, 2019, the parties entered into a Stipulation and Agreement of Settlement (the “Wilson Settlement Agreement”), pursuant to which the settlement amount of approximately $18.5 million was paid in March by our insurers on behalf of LSB and certain current and former officers in exchange for, among other things, a release of all claims. On May 23, 2019, one request for exclusion from the settlement class was made. On June 28, 2019, the court held a settlement hearing and entered a Judgement Approving Class Action Settlement, which includes a provision whereby the party requesting exclusion may withdraw its exclusion from the settlement and file by July 23, 2019 to rejoin the class. On July 23, 2019, LSB reached a preliminary settlement and the requesting party withdrew its request for exclusion from the class. Subsequently, during the third quarter of 2019, this additional settlement was executed, and the settlement amount was paid to the requesting party by our insurers on behalf of LSB and certain current and former officers in exchange for, among other things, an appropriate release of claims. As a result, no liability in relation to this matter remains outstanding as of December 31, 2019. In 2015, we and EDA received formal written notice from Global Industrial, Inc. (“Global”) of Global’s intention to assert mechanic liens for labor, service, or materials furnished under certain subcontract agreements for the improvement of the new ammonia plant at our El Dorado Facility. Global is a subcontractor of Leidos Constructors, LLC (“Leidos”), the general contractor for EDA for the construction for the ammonia plant. Leidos terminated the services of Global with respect to their work performed at our El Dorado Facility. LSB and EDA intend to pursue recovery of any damage or loss caused by Global’s work performed at our El Dorado Facility. In March 2016, EDC and we were served a summons in a case styled Global Industrial, Inc. d/b/a Global Turnaround vs. Leidos Constructors, LLC et al., in the Circuit court of Union County, Arkansas, wherein Global seeks damages under breach of contract and other claims. We have requested indemnifications from Leidos under the terms of our contracts which they have denied, and we intend to vigorously defend against the allegation made by Global and seek reimbursement of legal expenses from Leidos under our contracts. We are also seeking damages from Leidos for their wrongdoing during the expansion, including breach of contract, fraud, gross negligence, professional negligence and gross negligence. Except for the invoices totaling approximately $3.5 million that were not approved by Leidos for payment that are included in our accounts payable, no liability has been established in connection with the claims asserted by Global. On September 25, 2018, the Court bifurcated the case into: (1) Global’s claims against Leidos and LSB, and (2) the cross-claims between Leidos and LSB. Part (1) of the case was tried to the Court during the fall of 2018. The Court took the matter under advisement, will consider the evidence and render judgment. LSB intends to vigorously prosecute its claims against Leidos in Part (2) of the matter. Trial is scheduled for Part (2) of the matter in March of 2020. We are also involved in various other claims and legal actions (including matters involving gain contingencies). 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.

If there is a change in control of EDN, Covestro has the right to terminate the Covestro Agreement upon payment of certain fees to EDN. The Covestro Agreement expires in June 2021, with options for renewal.

Natural Gas Purchase and Other Commitments – Certain of our subsidiaries are parties to contracts to purchase natural gas for anticipated production needs at certain of our facilities. Since these contracts are considered normal purchases because they provide for the purchase of natural gas that will be delivered in quantities expected to be used over a reasonable period of time in the normal course of business and are documented as such, these contracts are exempt from the accounting and reporting requirements relating to derivatives. At December 31, 2019, our natural gas contracts, which qualify as normal purchases under GAAP and thus are not mark-to-market, included volume purchase commitments with fixed costs of approximately 7.0 million MMBtus of natural gas. These contracts extend through December 2020 at a weighted-average cost of $2.23 per MMBtu ($15.7 million) and a weighted-average market value of $2.06 per MMBtu ($14.5 million).

In addition, we had standby letters of credit outstanding of approximately $2.8 million at December 31, 2019.

Wastewater Pipeline Operating Agreement – EDC is party to an operating agreement for the right to use a pipeline to dispose its wastewater. EDC is contractually obligated to pay a portion of the operating costs of the pipeline, which portion is estimated to be $100,000 to $150,000 annually. The initial term of the operating agreement is through December 2053.

Performance and Payment Bonds – We are contingently liable to sureties in respect of certain insurance bonds issued by the sureties in connection with certain contracts entered into by certain subsidiaries in the normal course of business. These insurance bonds primarily represent guarantees of future performance of our subsidiaries. As of December 31, 2019, we have agreed to indemnify the sureties for payments, up to $10 million, made by them in respect of such bonds. All of these insurance bonds are expected to expire or be renewed in 2020.

9. Commitments and Contingencies (continued)

Employment and Severance Agreements - We have employment and severance agreements with several of our officers. The agreements, as amended, provide for annual base salaries, bonuses and other benefits commonly found in such agreements. In the event of termination of employment due to a change in control (as defined in the agreements), the agreements provide for payments aggregating $8.3 million at December 31, 2019. Also see Note 14-Related Party Transactions.

Settlement of a Gain Contingency - During 2018, we and a vendor mediated a settlement relating primarily to a business interruption claim caused by defective work performed by the vendor at our Pryor Facility. As a result of the settlement, the vendor paid us $4.0 million. As part of the settlement, we paid the vendor $0.5 million to settle $1.1 million of invoices that were held in our accounts payable. As a result, we recognized a recovery from this settlement totaling $4.6 million of which $4.4 million was classified as a reduction to cost of sales (primarily relating to our business interruption claim) and the remaining balance of $0.2 million as a reduction to PP&E.

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

A. Environmental Matters

Our facilities and operations are subject to numerous federal, state and local environmental laws and to other laws regarding health and safety matters (collectively, the “Environmental and Health Laws”), many of which provide for certain performance obligations, substantial fines and criminal sanctions for violations. Certain Environmental and Health Laws impose strict liability as well as joint and several liability for costs required to remediate and restore sites where hazardous substances, hydrocarbons or solid wastes have been stored or released. We may be required to remediate contaminated properties currently or formerly owned or operated by us or facilities of third parties that received waste generated by our operations regardless of whether such contamination resulted from the conduct of others or from consequences of our own actions that were in compliance with all applicable laws at the time those actions were taken.

In addition, claims for damages to persons or property, including natural resources, may result from the environmental, health and safety effects of our operations.

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. Our insurance may not cover all environmental risks and costs or may not provide sufficient coverage if an environmental claim is made against us. The Environmental and Health Laws and related enforcement policies have in the past resulted, and could in the future result, in significant compliance expenses, cleanup costs (for our sites or third-party sites where our wastes were disposed of), penalties or other liabilities relating to the handling, manufacture, use, emission, discharge or disposal of hazardous or toxic materials at or from our facilities or the use or disposal of certain of its chemical products. Further, a number of our facilities are dependent on environmental permits to operate, the loss or modification of which could have a material adverse effect on their operations and our financial condition.

Historically, significant capital expenditures have been incurred by our subsidiaries in order to comply with the Environmental and Health Laws, and significant capital expenditures are expected to be incurred in the future. We will also be obligated to manage certain discharge water outlets and monitor groundwater contaminants at our facilities should we discontinue the operations of a facility.

As of December 31, 2019, our accrued liabilities for environmental matters totaled $183,000 relating primarily to the matters discussed below. It is reasonably possible that a change in the estimate of our liability could occur in the near term. Also, see discussion in Note 6 – Asset Retirement Obligations.

1. Discharge Water Matters

Each of our manufacturing facilities generates process wastewater, which may include cooling tower and boiler water quality control streams, contact storm water and miscellaneous spills and leaks from process equipment. The process water discharge, storm-water runoff and miscellaneous spills and leaks are governed by various permits generally issued by the respective state environmental agencies as authorized and overseen by the U.S. Environmental Protection Agency. These permits limit the type and amount of effluents that can be discharged and control the method of such discharge.

9. Commitments and Contingencies (continued)

In October 2017, PCC filed a Permit Renewal Application for its Non-Hazardous Injection Well Permit at the Pryor Facility. Although the Injection Well Permit expired in 2018, PCC continues to operate the injection well pending the Oklahoma Department of Environmental Quality (“ODEQ”) action on the Permit Renewal Application. PCC and ODEQ are engaged in ongoing discussions related to the renewal of the injection well to address the wastewater stream.

Our El Dorado Facility is subject to a National Pollutant Discharge Elimination System (“NPDES”) permit issued by the Arkansas Department of Environmental Quality (“ADEQ”) in 2004. In 2010, the ADEQ issued a draft NPDES permit renewal for the El Dorado Facility, which contained more restrictive discharge limits than the previous 2004 permit. In August 2017, ADEQ issued a final NPDES permit with new dissolved mineral limits. EDC filed an appeal in September 2017 and a Permit Appeal Resolution (“PAR”) was signed in July 2018. EDC is in compliance with the revised permit limits agreed upon in the PAR.

In November 2006, the El Dorado Facility entered into a Consent Administrative Order (“CAO”) that recognizes the presence of nitrate contamination in the shallow groundwater. The CAO required EDC to perform semi-annual groundwater monitoring, continue operation of a groundwater recovery system, submit a human health and ecological risk assessment, and submit a remedial action plan. The risk assessment was submitted in August 2007. In February 2015, the ADEQ stated that El Dorado Chemical was meeting the requirements of the CAO and should continue semi-annual monitoring. Subsequent to the PAR mentioned previously, a new CAO was signed in October 2018, which required an Evaluation Report of the data and effectiveness of the groundwater remedy for nitrate contamination. In February 2019, the Evaluation Report was submitted to the ADEQ and the ADEQ approved the report in August 2019.

No liability has been established at December 31, 2019, in connection with this ADEQ matter.

2. Other Environmental Matters

In 2002, certain of our subsidiaries sold substantially all of their operating assets relating to a Kansas chemical facility (the “Hallowell Facility”) but retained ownership of the real property where the facility is located. 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.

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

Our subsidiary and Chevron have retained an environmental consultant to prepare and perform a corrective action study work plan as to the appropriate method to remediate the Hallowell Facility. The proposed strategy includes long-term surface and groundwater monitoring to track the natural decline in contamination. The KDHE is currently evaluating the corrective action strategy, and, thus, it is unknown what additional work the KDHE may require, if any, at this time.

We accrued our allocable portion of costs primarily for the additional testing, monitoring and risk assessments that could be reasonably estimated, which is included in our accrued liabilities for environmental matters discussed above. The estimated amount is not discounted to its present value. As more information becomes available, our estimated accrual will be refined.

B. Other Pending, Threatened or Settled Litigation

In 2013, an explosion and fire occurred at the West Fertilizer Co. (“West Fertilizer”) located in West, Texas, causing death, bodily injury and substantial property damage. West Fertilizer is not owned or controlled by us, but West Fertilizer was a customer of EDC, and purchased AN from EDC from time to time. LSB and EDC received letters from counsel purporting to represent subrogated insurance carriers, personal injury claimants and persons who suffered property damages informing LSB and EDC that their clients are conducting investigations into the cause of the explosion and fire to determine, among other things, whether AN manufactured by EDC and supplied to West Fertilizer was stored at West Fertilizer at the time of the explosion and, if so, whether such AN may have been one of the contributing factors of the explosion. Initial lawsuits filed named West Fertilizer and another supplier of AN as defendants.

In 2014, EDC and LSB were named as defendants, together with other AN manufacturers and brokers that arranged the transport and delivery of AN to West Fertilizer, in the case styled City of West, Texas vs. CF Industries, Inc., et al., in the District Court of McLennan County, Texas. The plaintiffs allege, among other things, that LSB and EDC were negligent in the production and marketing of fertilizer products sold to West Fertilizer, resulting in death, personal injury and property damage. EDC retained a firm specializing in cause and origin investigations with particular experience with fertilizer facilities, to assist EDC in its own investigation. LSB and EDC placed its liability insurance carrier on notice, and the carrier is handling the defense for LSB and EDC concerning this matter.

9. Commitments and Contingencies (continued)

Our product liability insurance policies have aggregate limits of general liability totaling $100 million, with a self-insured retention of $250,000, which retention limit has been met relating to this matter. In August 2015, the trial court dismissed plaintiff’s negligence claims against us and EDC based on a duty to inspect but allowed the plaintiffs to proceed on claims for design defect and failure to warn.

Subsequently, we and EDC have entered into confidential settlement agreements (with approval of our insurance carriers) with several plaintiffs that had claimed wrongful death and bodily injury and insurance companies asserting subrogation claims for damages from the explosion.

While these settlements resolve the claims of a number of the claimants in this matter for us, we continue to be party to litigation related to this explosion by other plaintiffs, in addition to indemnification or defense obligations we may have to other defendants. We continue to defend these lawsuits vigorously and we are unable to estimate a possible range of loss at this time if there is an adverse outcome in this matter as to EDC. As of December 31, 2019, no liability reserve has been established in connection with this matter.

In 2015, a case styled Dennis Wilson vs. LSB Industries, Inc., et al., was filed in the United States District Court for the Southern District of New York. The plaintiff purports to represent a class of our shareholders and asserts that we violated federal securities laws by allegedly making material misstatements and omissions about delays and cost overruns at our El Dorado Chemical Company manufacturing facility and about our financial well-being and prospects. The lawsuit, which also names certain current and former officers, sought an unspecified amount of damages.

In October 2018, LSB entered into a preliminary, binding term sheet to settle Dennis Wilson vs. LSB Industries, Inc., et al., which was subject to approval by the court. On January 17, 2019, the parties entered into a Stipulation and Agreement of Settlement (the “Wilson Settlement Agreement”), pursuant to which the settlement amount of approximately $18.5 million was paid in March by our insurers on behalf of LSB and certain current and former officers in exchange for, among other things, a release of all claims. On May 23, 2019, one request for exclusion from the settlement class was made. On June 28, 2019, the court held a settlement hearing and entered a Judgement Approving Class Action Settlement, which includes a provision whereby the party requesting exclusion may withdraw its exclusion from the settlement and file by July 23, 2019 to rejoin the class. On July 23, 2019, LSB reached a preliminary settlement and the requesting party withdrew its request for exclusion from the class. Subsequently, during the third quarter of 2019, this additional settlement was executed, and the settlement amount was paid to the requesting party by our insurers on behalf of LSB and certain current and former officers in exchange for, among other things, an appropriate release of claims. As a result, no liability in relation to this matter remains outstanding as of December 31, 2019.

In 2015, we and EDA received formal written notice from Global Industrial, Inc. (“Global”) of Global’s intention to assert mechanic liens for labor, service, or materials furnished under certain subcontract agreements for the improvement of the new ammonia plant at our El Dorado Facility. Global is a subcontractor of Leidos Constructors, LLC (“Leidos”), the general contractor for EDA for the construction for the ammonia plant. Leidos terminated the services of Global with respect to their work performed at our El Dorado Facility.

LSB and EDA intend to pursue recovery of any damage or loss caused by Global’s work performed at our El Dorado Facility. In March 2016, EDC and we were served a summons in a case styled Global Industrial, Inc. d/b/a Global Turnaround vs. Leidos Constructors, LLC et al., in the Circuit court of Union County, Arkansas, wherein Global seeks damages under breach of contract and other claims. We have requested indemnifications from Leidos under the terms of our contracts which they have denied, and we intend to vigorously defend against the allegation made by Global and seek reimbursement of legal expenses from Leidos under our contracts. We are also seeking damages from Leidos for their wrongdoing during the expansion, including breach of contract, fraud, gross negligence, professional negligence and gross negligence.

Except for the invoices totaling approximately $3.5 million that were not approved by Leidos for payment that are included in our accounts payable, no liability has been established in connection with the claims asserted by Global. On September 25, 2018, the Court bifurcated the case into: (1) Global’s claims against Leidos and LSB, and (2) the cross-claims between Leidos and LSB. Part (1) of the case was tried to the Court during the fall of 2018. The Court took the matter under advisement, will consider the evidence and render judgment. LSB intends to vigorously prosecute its claims against Leidos in Part (2) of the matter. Trial is scheduled for Part (2) of the matter in March of 2020.

We are also involved in various other claims and legal actions (including matters involving gain contingencies). 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.
