Accounting Policies [Abstract]
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, 2016 (“2016 Form 10-K”), filed with the Securities and Exchange Commission (“SEC”) on February 27, Basis of Consolidation - LSB Industries, Inc. (“LSB”) and its subsidiaries (the “Company”, “We”, “Us”, or “Our”) are consolidated in the accompanying condensed consolidated financial statements. LSB is a holding company with no significant operations or assets other than cash, cash equivalents, and investments in its subsidiaries. All material intercompany accounts and transactions have been eliminated. During May 2017, Zena Energy L.L.C. (“Zena”), which was an indirect, wholly owned subsidiary of LSB, entered into a purchase and sale agreement with BKV Chelsea, LLC, (“BKV”). Under the terms of the purchase and sale agreement, Zena agreed to sell to BKV substantially all of its assets, including Zena’s right, title, and interest in all of its oil and natural gas properties (the “Properties”) located in Wyoming County, Pennsylvania for a purchase price of approximately $16.3 million, subject to customary post-closing adjustments, which sale was completed on June 26, 2017. As a result, we recognized a loss on the sale of approximately $4.0 million which is included in operating other expense. The carrying value of the assets sold was approximately $20.0 million and was included in plant, property and equipment (“PP&E”) at December 31, 2016. Concurrently with the closing of the purchase and sale agreement, a portion of the net proceeds (approximately $3.5 million) was used to repay the remaining outstanding balance of a promissory note, which was secured by the Properties. Zena’s prior ownership of working interests in natural gas properties was accounted for as an undivided interest, whereby we reflected our proportionate share of the underlying assets, liabilities, revenues and expenses. The working interest represented our share of the costs and expenses incurred primarily to develop the underlying leaseholds and to produce natural gas while the net revenue interest represented our share of the revenues from the sale of natural gas. The net revenue interest was less than the working interest as the result of royalty interest due to others. We were not the operator of these natural gas properties. Nature of Business - We are engaged in the manufacture and sale of chemical products. The chemical products we primarily manufacture, market and sell are ammonia, fertilizer grade ammonium nitrate (“HDAN”), urea ammonium nitrate (“UAN”), and ammonium nitrate (“AN”) solution for agricultural applications, high purity and commercial grade ammonia, high purity AN, sulfuric acids, concentrated, blended and regular nitric acid, mixed nitrating acids, carbon dioxide, and diesel exhaust fluid for industrial applications, and industrial grade AN (“LDAN”) and solutions for the mining industry. We manufacture and distribute our products in four facilities; three of which we own and are located in El Dorado, Arkansas (the “El Dorado Facility”); Cherokee, Alabama (the “Cherokee Facility”); and Pryor, Oklahoma (the “Pryor Facility”); and one of which we operate on behalf of a global chemical company in Baytown, Texas (the “Baytown Facility”). Sales to customers include farmers, ranchers, fertilizer dealers and distributors primarily in the ranch land and grain production markets in the United States (U.S.); industrial users of acids throughout the U.S. and parts of Canada; and explosive manufacturers in the U.S. In our opinion, the unaudited condensed consolidated financial statements of the Company as of September 30, 2017 and for the three and nine months periods ended September 30, 2017 and 2016 include all adjustments and accruals, consisting of normal, recurring accrual adjustments, which are necessary for a fair presentation of the results for the interim periods. These interim results are not necessarily indicative of results for a full year due, in part, to the seasonality of our sales of agricultural products and the timing of performing our major plant maintenance activities. Our selling seasons for agricultural products are primarily during the spring and fall planting seasons, which typically extend from March through June and from September through November. Certain information and footnote disclosures normally included in financial statements prepared in accordance with 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 2016 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. Note 1: Summary of Significant Accounting Policies (continued) Concentration of Credit Risks for Cash and Cash Equivalents – Financial instruments relating to cash and cash equivalents potentially subject us to concentrations of credit risk. These financial instruments were held by financial institutions within the U.S. except for approximately $2.6 million. None of the financial instruments held within U.S. were in excess of the federally insured limits. Inventories - Inventories are stated at the lower of cost (determined using the first-in, first-out (“FIFO”) basis) or net realizable value, which is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, transportation or disposal. Finished goods include material, labor, and manufacturing overhead costs. On January 1, 2017, we adopted ASU No. 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory as discussed below in “Recently Issued Accounting Pronouncements”. Precious Metals - Precious metals are used as a catalyst in our manufacturing process. Precious metals are carried at cost, with cost being determined using the FIFO basis. Because some of the catalyst consumed in the production process cannot be readily recovered and the amount and timing of recoveries are not predictable, we follow the practice of expensing precious metals as they are consumed. Occasionally, during major maintenance or capital projects, we may be able to perform procedures to recover precious metals (previously expensed) which have accumulated over time within the manufacturing equipment. Recoveries of precious metals are recognized at historical FIFO costs. When we accumulate precious metals in excess of our production requirements, we may sell a portion of the excess metals. During the second quarter of 2017, we recognized a recovery of precious metals of approximately $2.9 million, which recovery is classified as a reduction to cost of sales. Recognition of Incentive Tax Credits (Other Than Credits Associated with Income Taxes) - If an incentive tax credit relates to a recovery of taxes (other than income taxes) incurred, we recognize the incentive tax credit when it is probable and reasonably estimable. If an incentive tax credit relates to an amount in excess of taxes incurred, the incentive tax credit is a contingent gain, which we recognize the incentive tax credit when it is realized or realizable and earned. Amounts recoverable from the taxing authorities, if any, are included in accounts receivable. The same financial statement classification is used for an incentive tax credit as the associated tax incurred. During the third quarter of 2017, we received notification from the State of Arkansas that incentive tax credits had been approved associated with certain capital expenditures associated with the El Dorado Facility’s expansion projects completed primarily in the fourth quarter of 2015 and the second quarter of 2016. As a result, we recognized a current and noncurrent receivable totaling approximately $8.1 million associated with these incentive tax credits with the offset reducing PP&E (covered by the tax credit) by approximately $7.4 million and the remaining balance of $0.7 million as a reduction to cost of sales (recovery of previously incurred depreciation expense related to the PP&E). Redeemable Preferred Stocks - Our redeemable preferred stocks that are redeemable outside of our control are classified as temporary/mezzanine equity. The redeemable preferred stocks were recorded at fair value upon issuance, net of issuance costs or discounts. In addition, certain embedded features included in the Series E Redeemable Preferred required bifurcation and are classified as derivative liabilities. The carrying values of the redeemable preferred stocks are being increased by periodic accretions (including the amount for dividends earned but not yet declared or paid) using the interest method so that the carrying amount will equal the redemption value as of August 2, 2019, the earliest possible redemption date by the holder. The amount of accretion was recorded to retained earnings. However, it is reasonably possible this accretion could accelerate if the expected redemption date is earlier than August 2, 2019. Income (Loss) per Common Share - Net income (loss) attributable to common stockholders is computed by adjusting net income (loss) by the amount of dividends and dividend requirements on preferred stocks and the accretion of redeemable preferred stocks, if applicable. B asic loss per common share is computed by dividing net loss at tributable to common stockholders by the weighted average number of common shares outstanding, excluding contingently returnable common shares (unvested restricted stock), if applicable. For periods we earn net income, a proportional share of net income is allocated to participating securities, if applicable, determined by dividing total weighted average participating securities by the sum of the total weighted average common shares and participating securities (the “two-class method”). Certain securities (Series E Redeemable Preferred and restricted stock units) participate in dividends declared on our common stock and are therefore considered to be participating securities. Participating securities have the effect of diluting both basic and diluted income per common share during periods of net income. For periods we incur a net loss, no loss is allocated to participating securities because they have no contractual obligation to share in our losses. Diluted loss per common share is computed after giving consideration to the dilutive effect of our potential common stock instruments that are outstanding during the period, except where such non-participating securities would be anti-dilutive. Note 1: Summary of Significant Accounting Policies (continued) Recently Issued Accounting Pronouncements - In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2014-09, Revenue from Contracts with Customers (Topic 606) , which will supersede nearly all existing revenue recognition guidance under GAAP. This ASU’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. In July 2015, the FASB approved a one-year deferral of the effective date of this ASU with the option to early adopt but not before the original effective date. In addition, the FASB has issued various ASUs further amending revenue recognition guidance, which includes ASU 2016-08, 2016-10, 2016-11, 2016-12 and 2016-20. We plan to adopt this ASU on the effective date of January 1, 2018 using the “modified retrospective” adoption method, meaning the standard is applied only to the most current period presented in the financial statements and apply only to existing contracts as of the effective date. We have performed a review of a majority of our contracts with customers with significant sales in 2016. Most of these contracts are short-term (have been completed or will be completed before the effective date); however, we do have certain long-term sales contracts that may be affected by the new requirements. In addition, although most of our revenue stream relates to the sale of chemical products, we have identified additional smaller revenue streams, such as performing various services, and rental income. A contract review process has been implemented to obtain and review our new or amended contracts for analysis for adopting this ASU. We are currently implementing changes to our processes, systems and controls to improve the ability to access, analyze, classify and account for our contracts. In addition, we are implementing a process to identify, store and access data needed for the new disclosure requirements. We have developed an accounting policy and the methodology of identifying performance obligations, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation for the contacts that will be affected. We plan to elect an accounting policy to account for shipping and handling activities performed after a customer obtains control of the good as activities to fulfil the promise to transfer the good to the customer. We also plan to elect an accounting policy to exclude from the measurement of the transaction price all taxes assessed by a governmental authority that are both imposed on, and concurrent with, a specific revenue-producing transaction and collected by us from a customer. Although we anticipate that upon adoption of this new ASU, the timing of revenue recognition and the financial statement presentation for certain of our revenue streams might change, we have not determined the effect on our financial statements. In July 2015, the FASB issued ASU No. 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) supersedes the lease requirements in Topic 840, Leases . The objective of this ASU is to establish the principles that lessees and lessors shall apply to report useful information to users of financial statements about the amount, timing, and uncertainty of cash flows arising from a lease. We plan to adopt this ASU on January 1, 2019. ented. Although we currently have a relatively small number of leases, we are evaluating the effect of this guidance on our consolidated financial statements and related disclosures. In March 2016, the FASB issued ASU No. 2016-09, Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, which amends A S C Topic 718, Compensation - Stock Compensation. This guidance previous windfalls, and then to the income statement. As required, this change was applied prospectively to all excess tax benefits and tax deficiencies resulting from settlements. Note 1: Summary of Significant Accounting Policies (continued) Under the new guidance, the windfall tax benefit is to be recorded when it arises, subject to normal valuation allowance considerations. Excess tax benefits that were not previously recognized because the related tax deduction had not reduced current taxes payable were recorded through a cumulative effect adjustment as of the date of the adoption. As required, this change was applied on a modified retrospective basis, with a cumulative effect adjustment of change in accounting principle of approximately $1.1 million as a deferred tax asset with the offset in retained earnings. We made an accounting policy election to account for the amount related to excess tax benefits and deficiencies utilizing the direct effect approach. Under the new guidance, all tax related cash flows resulting from share-based payments are to be reported as operating activities on the statement of cash flows, a change from activities. In addition, cash paid by an employer to taxing authorities when the employer directly withholds shares for tax withholding purposes is to be reported as financing activities. These changes were applied on a retrospective basis, but did not impact the statement of cash flows for the nine months ended September 30, 2016. Under the new guidance, we made an accounting policy election to account for forfeitures as t hey occur, a change from the previous requirement to estimate forfeitures each period. As required, this change was applied on a modified retrospective basis; however, as of December 31, 2016, we had estimated no forfeitures relating to the outstanding equity awards. As a result, no adjustment was required. Going forward, the adoption of this ASU could cause volatility in the effective tax rate. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash, a consensus of the FASB Emerging Issues Task Force. restricted cash equivalents) on the statement of cash flows. This ASU is effective for us on January 1, 2018 and adoption will be applied on retrospective basis for all periods presented. We plan to adopt this ASU on January 1, 201

Discontinued Operations And Disposal Groups [Abstract]
Discontinued Operations	Note 2: Discontinued Operations On July 1, 2016, LSB completed the sale of all the stock of Climate Control Group Inc. (an indirect subsidiary that conducted LSB’s Climate Control Business) pursuant to the terms of the stock purchase agreement. Additionally, pursuant to the stock purchase agreement, we agreed to have a certain portion of the purchase price proceeds deposited in an indemnity escrow account. In conjunction with the Climate Control Business sale, we entered into a transition services agreement (“TSA”), pursuant to which, among other things, we agreed to provide certain information technology, payroll, legal, tax and other general services, which services have been completed.

Asset Retirement Obligation Disclosure [Abstract]
Asset Retirement Obligations	Note 6: Asset Retirement Obligations Currently, we have various legal requirements related to operations of our chemical facilities, including the disposal of waste water generated at certain of these facilities. Additionally, we have certain chemical facilities 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 these facilities have an indefinite expected life. As a result, a liability for only a minimal amount relating to AROs associated with certain facilities has been established. However, we will continue to review these obligations and record a liability when a reasonable estimate of the fair value can be made. As the result of the sale of Zena’s working interests in certain natural gas properties during the second quarter of 2017, our previously recognized AR Os of approximately $193,000 associated with t as operating other expense. $546,000

At September 30, 2017, our available borrowings under our Working Capital Revolver Loan were approximately $38.6 m illion, ba sed o n our eligible collateral, less outstanding letters of credit. The maturity date of the Working Capital Revolver Loan is January 17, 2022, with a springing earlier maturity date (the “Springing Maturity Date”) that is 90 days prior to the maturity date of our Senior Secured Notes, to the extent the Senior Secured Notes are not refinanced or repaid prior to the Springing Maturity Date. The Working Capital Revolver Loan also provides for a springing financial covenant (the “Financial Covenant”), which requires that, if the borrowing availability is less than or equal to the greater of 10.0% of the total revolver commitments and $5 million, then the borrowers must maintain (a) with respect to relevant periods ending on or prior to September 30, 2017, a minimum EBITDA in the amount set forth in the Working Capital Revolver Loan Amendment and (b) with respect to relevant periods ending after September 30, 2017, a minimum fixed charge coverage ratio of not less than 1.00 to 1.00. The Financial Covenant, if triggered, is tested monthl y. (B) The Senior Secured Notes mature on August 1, 2019. Interest is to be paid semiannually on February 1st and August 1st. In September 2016, we entered into the First Supplemental Indenture to the original Indenture (the “Origi nal 7.75 In denture”) that, among other things, increased the annual interest rate to 8.5 % from 7.75%, effective August 1, 2016. (C) During the second quarter of 2017, concurrently with the closing of the purchase and sale agreement relating to Zena discussed in Note 1, a portion of the net proceeds (approximately $3.5 million) from the sale was used to repay the remaining outstanding balance of this promissory note.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 8: Commitments and Contingencies Natural Gas Purchase Commitments – At September 30, 2017, our natural gas contracts, which are exempt from mark-to-market accounting, included volume purchase commitments with fixed prices of approximately 2.4 million MMBtus of natural gas. These contracts extend through December 2017 at a weighted-average cost of $2.78 per MMBtu ($6.5 million) and a weighted-average market value of $2.75 per MMBtu ($6.5 million). Legal Matters - Following is a summary of certain legal matters involving the Company: A. Environmental Matters Our facilities and operations are subject to numerous federal, state and local environmental laws and to other laws regarding health and safety matters (collectively, the “Environmental and Health Laws”). In particular, the manufacture, production and distribution of products activities that entail environmental and public health risks and impose obligations under the Environmental and Health Laws, many of which provide for certain performance obligations, substantial fines and criminal sanctions for violations. 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 connection with certain acquisitions, we could acquire, or be required to provide indemnification against, environmental liabilities that could expose us to material losses. In certain instances, citizen groups also have the ability to bring legal proceedings against us if we are not in compliance with environmental laws, or to challenge our ability to receive environmental permits that we need to operate. 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. 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. We did not operate the natural gas wells where we previously owned a working interest and compliance with Environmental and Health Laws was controlled by others. We were responsible for our working interest proportionate share of the costs involved. As of September 30, 2017, our accrued liabilities for environmental matters total ed $126,000 relating primarily to – 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 (the “EPA”). These permits limit the type and amount of effluents that can be discharged and control the method of such discharge. Our facility located in Pryor, Oklahoma (the “Pryor Facility”) is authorized by underground injection through following its expiration, waste water has engaged in ongoing discussions regarding future disposal of this 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 contains more restrictive discharge limits than the previous 2004 permit. Note 8: Commitments and Contingencies (continued) These more restrictive limits could impose additional costs on the El Dorado Facility, and may require the facility to make operational changes in order to meet these more restrictive limits. From time to time, the El Dorado Facility has had difficulty meeting the more restrictive dissolved minerals NPDES permit levels, primarily related to storm-water runoff and EDC is currently working with ADEQ to resolve this issue through a new permit, which is currently in progress. EDC believes that the El Dorado Facility has generally demonstrated its ability to comply with applicable ammonia and nitrate permit levels, but has, from time to time, had difficulty meeting the more restrictive dissolved minerals permit levels, primarily related to storm-water runoff. We do not believe this matter regarding meeting the permit requirements as to the dissolved minerals is a continuing issue for the process wastewater as the result of the El Dorado Facility disposing its wastewater (beginning in September 2013) via a pipeline constructed by the City of El Dorado, Arkansas. On August 30, 2017, ADEQ issued a final NPDES permit, which included new dissolved mineral limits as anticipated. However, EDC has objections to the form of the permit and filed an appeal on September 27, 2017. The appeal places an automatic stay on the objectionable conditions and EDC is working with the ADEQ to obtain modifications to the renewed permit terms. We believe that the issue with the storm-water runoff should be resolved, if and when the appeal is resolved. We expect that the appeal will take a minimum of six months to resolve. During 2012, EDC paid a penalty of $100,000 to settle an administrative complaint issued by the EPA, and thereafter handled by the U.S. Department of Justice (“DOJ”), relating to certain alleged violations of EDC’s 2004 NPDES permit from 2004 through 2010. At the time of settlement, the DOJ advised that an additional action may be brought for alleged permit violations occurring after 2010. As of the date of this report, no action has been filed by the DOJ against EDC. As a result, the cost (or range of costs) cannot currently be reasonably estimated regarding this matter. Therefore, no liability has been established for potential future penalties as of September 30, In addition, the El Dorado Facility is currently operating under a consent administrative order (the “CAO”) that recognizes the presence of nitrate contamination in the shallow groundwater. The 2006 CAO required EDC to continue semiannual groundwater monitoring, to continue operation of a groundwater recovery system and to submit a human health and ecological risk assessment to the ADEQ relating to the El Dorado Facility. The risk assessment was submitted in August 2007. In February 2015, the ADEQ stated that El Dorado Chemical was meeting the requirements of the CAO and should continue semi-annual monitoring. The final remedy for shallow groundwater contamination, should any remediation be required, will be selected pursuant to a new consent administrative order and based upon the risk assessment. The cost of any additional remediation that may be required will be determined based on the results of the investigation and risk assessment, of which cost (or range of costs) cannot currently be reasonably estimated. Therefore, no liability has been established at September 2017 2. Air Matters PCC has been advised by the ODEQ that the agency is conducting an investigation into whether the Pryor Facility is in compliance with certain ODEQ air quality rules and regulations and whether PCC’s reports of certain air emissions, primarily in 2011, were intentionally misreported to the ODEQ. PCC is cooperating with the ODEQ in connection with this ongoing investigation. As of September 30 3. Other Environmental Matters In 20 02, certain of o 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 p a e cos Note 8: Commitments and Contingencies (continued) 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 are advised by our consultant that until the study is completed there is not sufficient information to develop a meaningful and reliable estimate (or range of estimate) as to the cost of the remediation. We accrued our allocable portion of costs primarily for the additional testing, monitoring and risk assessments that could be reasonably estimated, which is included in our accrued liabilities for environmental matters discussed above. The estimated amount is not discounted to its present value. As more information becomes available, our estimated accrual will be refined . B. Other Pending, Threatened or Settled Litigation In April 2013, an explosion and fire occurred at the West Fertilizer Co. (“West Fertilizer”) located in West, Texas, causing death, bodily injury and substantial property damage. West Fertilizer is not owned or controlled by us, but West Fertilizer was a customer of EDC, 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. 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. A portion of these settlements have been paid by the insurer as of September 30, 2017. 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 intend to continue to defend these lawsuits vigorously and we are unable to estimate a possible range of loss at this time if there is an adverse outcome in this matter as to EDC. As of September 30, 2017, no liability reserve has been established in connection with this matter, except for the unpaid portion of the settlement agreements discussed above, but we have incurred professional fees up to our self-insured retention amount. In May 2015, our subsidiary, EDC, was sued in the matter styled BAE Systems Ordinance Systems, Inc. et al. vs. El Dorado Chemical Company force majeure force majeure In September 2015, a case styled Dennis Wilson vs. LSB Industries, Inc Note 8: Commitments and Contingencies (continued) In September 2015, we and El Dorado Ammonia L.L.C. (“EDA”) received formal written notice from Global Industrial, Inc. (“Global”) of Global’s intention to assert mechanic liens for labor, service, or materials furnished under certain subcontract agreements for the improvement of the new ammonia plant at our El Dorado Facility. Global is a subcontractor of Leidos Constructors, LLC (“Leidos”), the general contractor for EDA for the construction for the ammonia plant. Leidos terminated the services of Global with respect to their work performed at our El Dorado Facility in July 2015 and Global claims it is entitled to payment for certain work prior to its termination in the sum of approximately $18 million. Leidos reports that it made an estimated $6 million payment to Global on or about September 11, 2015, and EDA paid Leidos approximately $3.5 million relating to work performed by subcontractors of Global. Leidos has not approved certain payments to Global pending the result of on-going audits and investigation undertaken to quantify the financial impact of Global’s work. EDA intends to monitor the Leidos audit, and conduct its own investigation, in an effort to determine whether any additional payment should be released to Global for any work not in dispute. LSB and EDA intend to pursue recovery of any damage or loss caused by Global’s work performed at our El Dorado Facility. In January 2016, El Dorado, Leidos and Global reached an agreement whereby the approximately $3.6 million claims of Leidos’ remaining unpaid subcontracts, vendors and suppliers will be paid (and these suppliers and subcontractors will in turn issue releases of their respective claims and liens). In addition, Global will reduce the value of its claim as against Leidos, and its lien amount as against the project by a like amount. After all such lower tier supplier and subcontractors are satisfied, the Global claim and lien amount will be reduced to approximately $5 million. 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., We are also involved in various other claims and legal actions. 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.

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivatives, Hedges, Financial Instruments and Carbon Credits	Note 9: Derivatives, Hedges, Financial Instruments and Carbon Credits For the periods presented, the following significant instruments are accounted for on a fair value basis: Carbon Credits and Associated Contractual Obligation Periodically, we are issued climate reserve tonnes (“carbon credits”) by the Climate Action Reserve in relation to a greenhouse gas reduction project (“Project”) performed at the Baytown Facility. Pursuant to the terms of the agreement with Covestro, a certain portion of the carbon credits are to be sold and the proceeds given to Covestro to recover the costs of the Project, and any balance thereafter to be allocated between Covestro and EDN. We have no obligation to reimburse Covestro for their costs associated with the Project, except through the transfer or sale of the carbon credits when such credits are issued to us. The assets for carbon credits are accounted for on a fair value basis and the contractual obligations associated with these carbon credits are also accounted for on a fair value basis (unless we enter into a sales commitment to sell the carbon credits). At September 30, 2017 we had approximately 495,000 carbon credits ( none Note 9: Derivatives, Hedges, Financial Instruments and Carbon Credits (continued) Embedded Derivative Certain embedded features (“embedded derivative”) relating to the redemption of the Series E Redeemable Preferred, which includes certain contingent redemption features and the participation rights value have been bifurcated from the Series E Redeemable Preferred and recorded as a liabilit y. As the result of the Indenture Amendments in connection with the previously reported redemption of a portion of our Senior Secured Notes and the redemption of the portion of Series E Redeemable Preferred, e estimate that the contingent redemption feature has no fair value at September 30, 2017 based on low probability that the remaining shares of Series E Redeemable Preferred would be redeemed prior to August 2, 2019. A September 303,646 7.94 8.42 The following is a summary of the classifications of valuations of fair value: Level 1 - The valuations of contracts classified as Level 1 are based on quoted prices in active markets for identical contracts. At September 30, 2017 and December 31, 2016, we did not have any contracts classified as Level 1. Level 2 - 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 September 30, 2017 and December 31, 2016, we did not have any significant contracts classified as Level 2. Level 3 - 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 September 30, 2017, the valuation ($2.35 per carbon credit) of the carbon credits and the contractual obligations associated with these carbon credits is classified as Level 3 and is based on the most recent sales transaction and reevaluated for market changes, if any, and on the range of ask/bid prices obtained from a broker adjusted for minimal market volume activity. At December 31, 2016, we did not have any carbon credits or related contractual obligations associated with carbon credits. The valuation is 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. At September 30, 2017 and December 31, 2016, the valuations of the embedded derivative are classified as Level 3. This derivative is valued using market information, management’s redemption assumptions, the underlying number of shares as defined in the terms of the Series E Redeemable Preferred, and the market price of our common stock. In addition, no valuation input adjustments were considered necessary relating to nonperformance risk for the embedded derivative. The following details our assets and liabilities that are measured at fair value on a recurring basis at September 30, 2017 and December 31, 2016: Fair Value Measurements at September 30, 2017 Using Description Total Fair Value at September 30, 2017 Quoted Prices in Active Markets for Identical Contracts (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total Fair Value at December 31, 2016 (In Thousands) Assets - Supplies, prepaid items and other: Carbon credits $ 1,164 $ — $ — $ 1,164 $ — Total $ 1,164 $ — $ — $ 1,164 $ — Liabilities - Current and noncurrent accrued and other liabilities: Contractual obligations - carbon credits $ (1,164 ) $ — $ — $ (1,164 ) $ — Embedded derivative (2,411 ) — — (2,411 ) (2,557 ) Foreign exchange contracts — — — — (1 ) Total $ (3,575 ) $ — $ — $ (3,575 ) $ (2,558 ) Note 9: Derivatives, Hedges, Financial Instruments and Carbon Credits (continued) None of our liabilities measured at fair value on a recurring basis transferred between Level 1 and Level 2 classifications for the periods presented below. As the result of entering into the stock purchase agreement relating to the sale of the Climate Control Business in 2016 as discussed in Note 2, the valuation of the embedded derivative transferred from Level 2 to Level 3 since the probability increased relating to contingent redemption features requiring the use of significant unobservable inputs. The classification transfer of this derivative was deemed to occur at the beginning of the second quarter of 2016. In addition, the following is a reconciliation of the beginning and ending balances for assets and liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3): Assets Liabilities Assets Liabilities Three Months Ended Three Months Ended Nine Months Ended Nine Months Ended September 30, September 30, September 30, September 30, 2017 2016 2017 2016 2017 2016 2017 2016 (In Thousands) Beginning balance $ — $ 6 $ (3,137 ) $ (1,871 ) $ — $ 1,154 $ (2,557 ) $ (1,154 ) Transfers into Level 3 — — — — — — — (5,817 ) Transfers out of Level 3 — — — — — — — — Total realized and unrealized gains (losses) included in operating results 1,164 1,196 (438 ) (3,395 ) 2,031 1,256 (1,705 ) 754 Purchases — — — — — — — — Issuances — — — — — — — — Sales — (1,202 ) — — (867 ) (2,410 ) — — Settlements — — — 2,661 — — 687 3,612 Ending balance $ 1,164 $ — $ (3,575 ) $ (2,605 ) $ 1,164 $ — $ (3,575 ) $ (2,605 ) Total gains (losses) for the period included in operating results attributed to the change in unrealized gains or losses on assets and liabilities still held at the reporting date $ 1,164 $ — $ (438 ) $ (2,199 ) $ 1,164 $ — (1,018 ) $ (816 ) Net gains (losses) included in continuing operating results and the statement of operations classifications are as follows: Three Months Ended Nine Months Ended September 30, September 30, 2017 2016 2017 2016 (In Thousands) Total net gains (losses) included in operating results: Cost of sales - Undesignated commodities contracts $ — $ 18 $ — $ 81 Cost of sales - Undesignated foreign exchange contracts — 1 — 7 Other income - Carbon credits 1,164 1,196 2,031 1,513 Other expense - Contractual obligations relating to carbon credits (1,164 ) (922 ) (1,851 ) (982 ) Non-operating other income (expense) - embedded derivative 726 (2,474 ) 146 (1,031 ) Total net gains (losses) included in operating results $ 726 $ (2,181 ) $ 326 $ (412 ) Note 9: Derivatives, Hedges, Financial Instruments and Carbon Credits (continued) At September 30, 2017 and December 31, 2016, we did not have any financial instruments with fair values significantly different from their carrying amounts (which excludes issuance costs, if applicable), except for the Senior Secured Notes as shown below.

The valuations of our other long-term debt agreements are classified as Level 3 and are based on valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement. The fair value measurements of our other long-term debt agreements are valued using a discounted cash flow model that calculates the present value of future cash flows pursuant to the terms of the debt agreements and applies estimated current market interest rates. The estimated current market interest rates are based primarily on interest rates currently being offered on borrowings of similar amounts and terms. In addition, no valuation input adjustments were considered necessary relating to nonperformance risk for our debt agreements. The fair value of financial instruments is not indicative of the overall fair value of our assets and liabilities since financial instruments do not include all assets, including intangibles, and all liabilities. Also see discussions concerning certain assets and liabilities initially accounted for on a fair value basis under Note 6 - Asset Retirement Obligations.

Our annual estimated effective rate for 2017 includes the impact of permanent tax differences, such as a loss on embedded derivatives, valuation allowances, and other permanent items. Note 10: Income Taxes (continued) We reduce our deferred tax assets by a valuation allowance if, based upon the weight of available evidence, it is more-likely-than-not that we will not realize some portion or all of the deferred tax assets. We consider relevant evidence, both positive and negative, to determine the need for a valuation allowance. Information evaluated includes our financial position and results of operations for the current and preceding years, the availability of deferred tax liabilities and tax carrybacks, as well as an evaluation of currently available information about future years. We determined it was more-likely-than-not that a portion of the state NOL carryforwards would not be able to be utilized before expiration and we estimate the valuation allowance associated with these state NOL carryforwards to be recorded during 2017 will be approximately $ We will continue to evaluate both the positive and negative evidence on a quarterly basis in determining the need for a valuation allowance with respect to our deferred tax assets. Changes in positive and negative evidence, including differences between estimated and actual results, could result in changes in the valuation of our deferred tax assets that could have a material impact on our consolidated financial statements. Changes in existing tax laws could also affect actual tax results and the realization of deferred tax assets over time.

Related Party Transactions [Abstract]
Related Party Transactions	Note 12: Related Party Transactions I n September 2017, we received $2,300,000 as an advance payment on the potential sale of our engineered products business (industrial machinery and related components) as discussed in Note 14 – Subsequent Events. As the result of Jack E. Golsen, the Executive Chairman of our Board of Directors (the “Board”), informing the Board of his election to retire as Executive Chairman effective December 31, 2017, we determined not to extend the employment agreement with Mr. Golsen beyond its current term expiring on December 31, 2017 (the “Retirement Date”) and, in accordance with the terms of the Employment Agreement, delivered a notice of non-renewal to Mr. Golsen. Mr. Golsen will remain a member of the Board and, following the Retirement Date, will have the title of Chairman Emeritus. During the second quarter of 2017, we entered into a transition agreement (the “Transition Agreement”) with Mr. Golsen that will commence on January 1, 2018 and end upon the earlier of his death or a change in control as defined in the Transition Agreement. During the term, Mr. Golsen will receive an annual cash retainer of $480,000 and an additional monthly amount of $4,400 to cover certain expenses. In accordance with the terms of the Transition Agreement, we will also reimburse Mr. Golsen for his cost of certain medical insurance coverage until his death. Effective as of the Retirement Date, our existing severance agreement with Mr. Golsen will terminate. In consideration for his services, including as Chairman Emeritus, we will pay Mr. Golsen a one-time payment equal to $2,320,000 upon the consummation of a change in control that occurs prior to his death. During the first quarter of 2017, a death benefit agreement with Mr. Golsen was terminated pursuant to the terms of the agreement that allowed us to terminate at any time and for any reason prior to the death of the employee. As a result, the liability of approximately $1,400,000 for the estimated death benefit associated with this agreement was extinguished and derecognized with the offset classified as other income for the nine months ended September 30, 2017. No dividends were declared during the first nine months of 2017 or 2016. At September 30, 2017, accumulated dividends on the Series B and Series D Preferred totaled approxim ately $603,000. T

Summary of Significant Accoun21

Summary of Significant Accounting Policies (Policies)	9 Months Ended
	Sep. 30, 2017
Accounting Policies [Abstract]
Basis of Consolidation	Basis of Consolidation - LSB Industries, Inc. (“LSB”) and its subsidiaries (the “Company”, “We”, “Us”, or “Our”) are consolidated in the accompanying condensed consolidated financial statements. LSB is a holding company with no significant operations or assets other than cash, cash equivalents, and investments in its subsidiaries. All material intercompany accounts and transactions have been eliminated. During May 2017, Zena Energy L.L.C. (“Zena”), which was an indirect, wholly owned subsidiary of LSB, entered into a purchase and sale agreement with BKV Chelsea, LLC, (“BKV”). Under the terms of the purchase and sale agreement, Zena agreed to sell to BKV substantially all of its assets, including Zena’s right, title, and interest in all of its oil and natural gas properties (the “Properties”) located in Wyoming County, Pennsylvania for a purchase price of approximately $16.3 million, subject to customary post-closing adjustments, which sale was completed on June 26, 2017. As a result, we recognized a loss on the sale of approximately $4.0 million which is included in operating other expense. The carrying value of the assets sold was approximately $20.0 million and was included in plant, property and equipment (“PP&E”) at December 31, 2016. Concurrently with the closing of the purchase and sale agreement, a portion of the net proceeds (approximately $3.5 million) was used to repay the remaining outstanding balance of a promissory note, which was secured by the Properties. Zena’s prior ownership of working interests in natural gas properties was accounted for as an undivided interest, whereby we reflected our proportionate share of the underlying assets, liabilities, revenues and expenses. The working interest represented our share of the costs and expenses incurred primarily to develop the underlying leaseholds and to produce natural gas while the net revenue interest represented our share of the revenues from the sale of natural gas. The net revenue interest was less than the working interest as the result of royalty interest due to others. We were not the operator of these natural gas properties.
Nature of Business	Nature of Business - We are engaged in the manufacture and sale of chemical products. The chemical products we primarily manufacture, market and sell are ammonia, fertilizer grade ammonium nitrate (“HDAN”), urea ammonium nitrate (“UAN”), and ammonium nitrate (“AN”) solution for agricultural applications, high purity and commercial grade ammonia, high purity AN, sulfuric acids, concentrated, blended and regular nitric acid, mixed nitrating acids, carbon dioxide, and diesel exhaust fluid for industrial applications, and industrial grade AN (“LDAN”) and solutions for the mining industry. We manufacture and distribute our products in four facilities; three of which we own and are located in El Dorado, Arkansas (the “El Dorado Facility”); Cherokee, Alabama (the “Cherokee Facility”); and Pryor, Oklahoma (the “Pryor Facility”); and one of which we operate on behalf of a global chemical company in Baytown, Texas (the “Baytown Facility”). Sales to customers include farmers, ranchers, fertilizer dealers and distributors primarily in the ranch land and grain production markets in the United States (U.S.); industrial users of acids throughout the U.S. and parts of Canada; and explosive manufacturers in the U.S. In our opinion, the unaudited condensed consolidated financial statements of the Company as of September 30, 2017 and for the three and nine months periods ended September 30, 2017 and 2016 include all adjustments and accruals, consisting of normal, recurring accrual adjustments, which are necessary for a fair presentation of the results for the interim periods. These interim results are not necessarily indicative of results for a full year due, in part, to the seasonality of our sales of agricultural products and the timing of performing our major plant maintenance activities. Our selling seasons for agricultural products are primarily during the spring and fall planting seasons, which typically extend from March through June and from September through November. Certain information and footnote disclosures normally included in financial statements prepared in accordance with 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 2016 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.
Concentration of Credit Risks for Cash and Cash Equivalents	Concentration of Credit Risks for Cash and Cash Equivalents – Financial instruments relating to cash and cash equivalents potentially subject us to concentrations of credit risk. These financial instruments were held by financial institutions within the U.S. except for approximately $2.6 million. None of the financial instruments held within U.S. were in excess of the federally insured limits.
Inventories	Inventories - Inventories are stated at the lower of cost (determined using the first-in, first-out (“FIFO”) basis) or net realizable value, which is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, transportation or disposal. Finished goods include material, labor, and manufacturing overhead costs. On January 1, 2017, we adopted ASU No. 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory as discussed below in “Recently Issued Accounting Pronouncements”.
Precious Metals	Precious Metals - Precious metals are used as a catalyst in our manufacturing process. Precious metals are carried at cost, with cost being determined using the FIFO basis. Because some of the catalyst consumed in the production process cannot be readily recovered and the amount and timing of recoveries are not predictable, we follow the practice of expensing precious metals as they are consumed. Occasionally, during major maintenance or capital projects, we may be able to perform procedures to recover precious metals (previously expensed) which have accumulated over time within the manufacturing equipment. Recoveries of precious metals are recognized at historical FIFO costs. When we accumulate precious metals in excess of our production requirements, we may sell a portion of the excess metals. During the second quarter of 2017, we recognized a recovery of precious metals of approximately $2.9 million, which recovery is classified as a reduction to cost of sales.
Recognition of Incentive Tax Credits (Other Than Credits Associated with Income Taxes)	Recognition of Incentive Tax Credits (Other Than Credits Associated with Income Taxes) - If an incentive tax credit relates to a recovery of taxes (other than income taxes) incurred, we recognize the incentive tax credit when it is probable and reasonably estimable. If an incentive tax credit relates to an amount in excess of taxes incurred, the incentive tax credit is a contingent gain, which we recognize the incentive tax credit when it is realized or realizable and earned. Amounts recoverable from the taxing authorities, if any, are included in accounts receivable. The same financial statement classification is used for an incentive tax credit as the associated tax incurred. During the third quarter of 2017, we received notification from the State of Arkansas that incentive tax credits had been approved associated with certain capital expenditures associated with the El Dorado Facility’s expansion projects completed primarily in the fourth quarter of 2015 and the second quarter of 2016. As a result, we recognized a current and noncurrent receivable totaling approximately $8.1 million associated with these incentive tax credits with the offset reducing PP&E (covered by the tax credit) by approximately $7.4 million and the remaining balance of $0.7 million as a reduction to cost of sales (recovery of previously incurred depreciation expense related to the PP&E).
Redeemable Preferred Stocks	Redeemable Preferred Stocks - Our redeemable preferred stocks that are redeemable outside of our control are classified as temporary/mezzanine equity. The redeemable preferred stocks were recorded at fair value upon issuance, net of issuance costs or discounts. In addition, certain embedded features included in the Series E Redeemable Preferred required bifurcation and are classified as derivative liabilities. The carrying values of the redeemable preferred stocks are being increased by periodic accretions (including the amount for dividends earned but not yet declared or paid) using the interest method so that the carrying amount will equal the redemption value as of August 2, 2019, the earliest possible redemption date by the holder. The amount of accretion was recorded to retained earnings. However, it is reasonably possible this accretion could accelerate if the expected redemption date is earlier than August 2, 2019.
Income (Loss) per Common Share	Income (Loss) per Common Share - Net income (loss) attributable to common stockholders is computed by adjusting net income (loss) by the amount of dividends and dividend requirements on preferred stocks and the accretion of redeemable preferred stocks, if applicable. B asic loss per common share is computed by dividing net loss at tributable to common stockholders by the weighted average number of common shares outstanding, excluding contingently returnable common shares (unvested restricted stock), if applicable. For periods we earn net income, a proportional share of net income is allocated to participating securities, if applicable, determined by dividing total weighted average participating securities by the sum of the total weighted average common shares and participating securities (the “two-class method”). Certain securities (Series E Redeemable Preferred and restricted stock units) participate in dividends declared on our common stock and are therefore considered to be participating securities. Participating securities have the effect of diluting both basic and diluted income per common share during periods of net income. For periods we incur a net loss, no loss is allocated to participating securities because they have no contractual obligation to share in our losses. Diluted loss per common share is computed after giving consideration to the dilutive effect of our potential common stock instruments that are outstanding during the period, except where such non-participating securities would be anti-dilutive.
Recently Issued Accounting Pronouncements	Note 1: Summary of Significant Accounting Policies (continued) Recently Issued Accounting Pronouncements - In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2014-09, Revenue from Contracts with Customers (Topic 606) , which will supersede nearly all existing revenue recognition guidance under GAAP. This ASU’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. In July 2015, the FASB approved a one-year deferral of the effective date of this ASU with the option to early adopt but not before the original effective date. In addition, the FASB has issued various ASUs further amending revenue recognition guidance, which includes ASU 2016-08, 2016-10, 2016-11, 2016-12 and 2016-20. We plan to adopt this ASU on the effective date of January 1, 2018 using the “modified retrospective” adoption method, meaning the standard is applied only to the most current period presented in the financial statements and apply only to existing contracts as of the effective date. We have performed a review of a majority of our contracts with customers with significant sales in 2016. Most of these contracts are short-term (have been completed or will be completed before the effective date); however, we do have certain long-term sales contracts that may be affected by the new requirements. In addition, although most of our revenue stream relates to the sale of chemical products, we have identified additional smaller revenue streams, such as performing various services, and rental income. A contract review process has been implemented to obtain and review our new or amended contracts for analysis for adopting this ASU. We are currently implementing changes to our processes, systems and controls to improve the ability to access, analyze, classify and account for our contracts. In addition, we are implementing a process to identify, store and access data needed for the new disclosure requirements. We have developed an accounting policy and the methodology of identifying performance obligations, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation for the contacts that will be affected. We plan to elect an accounting policy to account for shipping and handling activities performed after a customer obtains control of the good as activities to fulfil the promise to transfer the good to the customer. We also plan to elect an accounting policy to exclude from the measurement of the transaction price all taxes assessed by a governmental authority that are both imposed on, and concurrent with, a specific revenue-producing transaction and collected by us from a customer. Although we anticipate that upon adoption of this new ASU, the timing of revenue recognition and the financial statement presentation for certain of our revenue streams might change, we have not determined the effect on our financial statements. In July 2015, the FASB issued ASU No. 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) supersedes the lease requirements in Topic 840, Leases . The objective of this ASU is to establish the principles that lessees and lessors shall apply to report useful information to users of financial statements about the amount, timing, and uncertainty of cash flows arising from a lease. We plan to adopt this ASU on January 1, 2019. ented. Although we currently have a relatively small number of leases, we are evaluating the effect of this guidance on our consolidated financial statements and related disclosures. In March 2016, the FASB issued ASU No. 2016-09, Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, which amends A S C Topic 718, Compensation - Stock Compensation. This guidance previous windfalls, and then to the income statement. As required, this change was applied prospectively to all excess tax benefits and tax deficiencies resulting from settlements. Note 1: Summary of Significant Accounting Policies (continued) Under the new guidance, the windfall tax benefit is to be recorded when it arises, subject to normal valuation allowance considerations. Excess tax benefits that were not previously recognized because the related tax deduction had not reduced current taxes payable were recorded through a cumulative effect adjustment as of the date of the adoption. As required, this change was applied on a modified retrospective basis, with a cumulative effect adjustment of change in accounting principle of approximately $1.1 million as a deferred tax asset with the offset in retained earnings. We made an accounting policy election to account for the amount related to excess tax benefits and deficiencies utilizing the direct effect approach. Under the new guidance, all tax related cash flows resulting from share-based payments are to be reported as operating activities on the statement of cash flows, a change from activities. In addition, cash paid by an employer to taxing authorities when the employer directly withholds shares for tax withholding purposes is to be reported as financing activities. These changes were applied on a retrospective basis, but did not impact the statement of cash flows for the nine months ended September 30, 2016. Under the new guidance, we made an accounting policy election to account for forfeitures as t hey occur, a change from the previous requirement to estimate forfeitures each period. As required, this change was applied on a modified retrospective basis; however, as of December 31, 2016, we had estimated no forfeitures relating to the outstanding equity awards. As a result, no adjustment was required. Going forward, the adoption of this ASU could cause volatility in the effective tax rate. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash, a consensus of the FASB Emerging Issues Task Force. restricted cash equivalents) on the statement of cash flows. This ASU is effective for us on January 1, 2018 and adoption will be applied on retrospective basis for all periods presented. We plan to adopt this ASU on January 1, 201
