Summary of Significant Accounting Policies	Dec. 31, 2016
Accounting Policies [Abstract]
Summary of Significant Accounting Policies	1. Summary of Significant Accounting Policies Basis of Consolidation - LSB Industries, Inc. (“LSB”) and its subsidiaries (the “Company”, “We”, “Us”, or “Our”) are consolidated in the accompanying consolidated financial statements. LSB is a holding company with no significant operations or assets other than cash, cash equivalents, and investments in its subsidiaries. Our ownership of working interests in natural gas properties is accounted for as an undivided interest, whereby we reflect our proportionate share of the underlying assets, liabilities, revenues and expenses. Our working interest represents our share of the costs and expenses incurred primarily to develop the underlying leaseholds and to produce natural gas while our net revenue interest represents our share of the revenues from the sale of natural gas. The net revenue interest is less than our working interest as the result of royalty interest due to others. We are not the operator of these natural gas properties. Entities that were 20% to 50% owned and for which we had significant influence were accounted for on the equity method. All material intercompany accounts and transactions have been eliminated. 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 AN (“HDAN”), UAN, and AN ammonia solution for agricultural applications, high purity and commercial grade ammonia, high purity AN, sulfuric acids, concentrated, blended and regular nitric acid, mixed nitrating acids, carbon dioxide, and diesel exhaust fluid for industrial applications, and industrial grade AN (“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; industrial users of acids throughout the United States (U.S.) and parts of Canada; and explosive manufacturers in the U.S. Our other products consist of natural gas sales from our working interests in certain natural gas properties and sales of industrial machinery and related components. For 2016, 2015 and 2014, these sales totaled $9.1 million, $12.9 million and $24.5 million, respectively. On May 11, 2016, LSB, Consolidated Industries L.L.C., a direct, wholly owned subsidiary of LSB (“Consolidated”), and Climate Control Group, Inc., a direct, wholly owned subsidiary of Consolidated and an indirect subsidiary of LSB (the “Climate Control Group”), entered into a Stock Purchase Agreement (the “Stock Purchase Agreement”) with NIBE Industrier AB (publ), and NIBE Energy Systems Inc., an indirect wholly owned subsidiary of NIBE Industrier AB (collectively “NIBE”) pursuant to which LSB, through Consolidated, agreed to sell to NIBE all of the outstanding shares of stock of the Climate Control Group for a total of approximately $364 million, subject to post-closing adjustments, which sale was completed on July 1, 2016. The Climate Control Group conducted LSB’s Climate Control Business (the “Climate Control Business”). The assets and liabilities of Climate Control Business have been reclassified and reported as held for sale as of December 31, 2015. Furthermore, the operating activities of Climate Control Business have been reclassified and reported as discontinued operations for all periods presented. Our financial statements and footnotes reflect our results from continuing operations unless otherwise noted. Our financial statements and footnotes reflect our results from continuing operations unless otherwise noted. See Note 2 – Discontinued Operations. Use of Estimates - The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Cash and Cash Equivalents – Investments, which consist of highly liquid investments with original maturities of three months or less, are considered cash equivalents. Accounts Receivable - Our accounts receivable are stated at net realizable value. This value includes an appropriate allowance for estimated uncollectible accounts to reflect any loss anticipated on accounts receivable balances. Our estimate is based on historical experience and periodic assessment of outstanding accounts receivable, particularly those accounts that are past due (based upon the terms of the sale). Our periodic assessment of our accounts receivable is based on our best estimate of amounts that are not recoverable. Inventories - Inventories are stated at the lower of cost (determined using the first-in, first-out (“FIFO”) basis) or market (net realizable value). Finished goods include material, labor, and manufacturing overhead costs. 1. Summary of Significant Accounting Policies (continued) 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. Property, Plant and Equipment - Property, plant and equipment (“PP&E”) are stated at cost, net of accumulated depreciation, depletion and amortization (“DD&A”). Leases meeting capital lease criteria are capitalized in PP&E. Major renewals and improvements that increase the life, value, or productive capacity of assets are capitalized in PP&E while maintenance, repairs and minor renewals are expensed as incurred. In addition, maintenance, repairs and minor renewal costs relating to planned major maintenance activities (“Turnarounds”) are expensed as they are incurred. All long-lived assets relate to domestic operations. As it relates to natural gas properties, leasehold costs, intangible drilling and other costs of successful wells and development dry holes are capitalized in PP&E based on successful efforts accounting. The costs of exploratory wells are initially capitalized in PP&E, but expensed if and when the well is determined to be nonproductive. Fully depreciated assets are retained in PP&E and accumulated DD&A accounts until disposal. When PP&E are retired, sold, or otherwise disposed, the asset’s carrying amount and related accumulated DD&A are removed from the accounts and any gain or loss is included in other income or expense. For financial reporting purposes, depreciation of the costs of PP&E is primarily computed using the straight-line method over the estimated useful lives of the assets. No provision for depreciation is made on construction in progress or capital spare parts until such time as the relevant assets are put into service. DD&A of the costs of producing natural gas properties are computed using the units of production method primarily on a field-by-field basis using total proved or proved developed reserves, as applicable, as estimated by our independent consulting petroleum engineer. No provision for DD&A is made on nonproducing leasehold costs and exploratory wells in progress until such time as the relevant assets relate to proven reserves. Our natural gas reserves are based on estimates and assumptions, which affect our DD&A calculations. Our independent consulting petroleum engineer, with our assistance, prepares estimates of natural gas reserves based on available relevant data and information. For DD&A purposes, and as required by the guidelines and definitions established by the Securities and Exchange Commission (“SEC”), the reserve estimates are based on average natural gas prices during the 12-month period, determined as an unweighted arithmetic average of the first-day-of-the-month price for each month. Impairment of Long-Lived Assets and Goodwill - Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset (asset group) may not be recoverable. An impairment loss would be recognized when the carrying amount of an asset (asset group) exceeds the estimated undiscounted future cash flows expected to result from the use of the asset (asset group) and its eventual disposition. If assets to be held and used are considered to be impaired, the impairment to be recognized is the amount by which the carrying amounts of the assets exceed the fair values of the assets as measured by the present value of future net cash flows expected to be generated by the assets or their appraised value. In general, and depending on the event or change in circumstances, our asset groups are reviewed for impairment on a facility-by-facility basis (such as the Cherokee, El Dorado or Pryor Facility). As it relates to natural gas properties, proven natural gas properties are reviewed for impairment on a field-by-field basis and nonproducing leasehold costs are reviewed for impairment on a property-by-property basis. In addition, if the event or change in circumstance relates to the possible sale of an asset (or group of assets), the specific asset (or group of assets) is reviewed for impairment. In addition, goodwill is reviewed for impairment at least annually. An impairment loss generally would be recognized when the carrying amount of the reporting unit’s net assets exceeds the estimated fair value of the reporting unit. At December 31, 2015, other assets included goodwill of $1.6 million related to the acquisition of our El Dorado Facility. See discussion below under 2016. In general, assets held for sale are reported at the lower of the carrying amounts of the assets or fair values less costs to sell. At December 31, 2015, long-lived assets classified as assets held for sale related to the Climate Control Business as discussed above and in Note 2 – Discontinued Operations (none at December 31, 2016). 1. Summary of Significant Accounting Policies (continued) The non-cash impairment charges discussed below were included in the consolidated statements of operations line item titled impairment of long-lived assets and goodwill. 2016 Generally, the evaluation of goodwill for impairment involves a two-step test. Step 1 involves comparing the estimated fair value of each respective reporting unit to its carrying value, including goodwill. Our step 1 test utilized both a market approach and income approach to estimate the fair values of our reporting units. The market approach was based on enterprise value to estimated EBITDA multiples of our peer group (Level 3 inputs). If the estimated fair value exceeds the carrying value, the reporting unit’s goodwill is not considered impaired. If the carrying value exceeds the estimated fair value, step 2 must be performed to determine whether goodwill is impaired and, if so, the amount of the impairment. Step 2 involves calculating an implied fair value of goodwill by performing a hypothetical allocation of the estimated fair value of the reporting unit determined in step 1 to the respective tangible and intangible net assets of the reporting unit (Level 3 inputs). The remaining implied goodwill is then compared to the actual carrying amount of the goodwill for the reporting unit. To the extent the carrying amount of goodwill exceeds the implied goodwill, the difference is the amount of the goodwill impairment. During 2016, pricing for our key product groups deteriorated well below expectations foreseen at December 31, 2015. Additionally, we believe the lower price environment is expected to continue throughout 2017. Thus, in accordance with ASC 350, we determined it was more likely than not that the fair value of goodwill related to our El Dorado Facility was less than its carrying amount (goodwill and other) implied under step 2 resulting in an impairment charge of $1.6 million to fully write-down the carrying value of goodwill. 2015 During 2015, we recognized an impairment charge of $39.7 million to write-down the carrying value ($62.2 million) of our working interest in natural gas properties in the Marcellus Shale region to their estimated fair value of $ 22.5 million. The impairment charge represented the amount by which the carrying value of these natural gas properties exceeded the estimated fair value and was therefore not recoverable. The estimated fair value was determined based on estimated future discounted net cash flows, a Level 3 input, using estimated production and prices at which we reasonably expect natural gas will be sold, including the evaluation provided by our independent consulting petroleum engineer in October 2015. The event triggering the review for impairment related primarily from the results received from the evaluation. The impairment was due to the decline in prices for natural gas futures, large natural gas price differentials in the Marcellus Shale region and the resulting changes in the drilling plans of these natural gas properties that caused certain of these properties to be reclassified from the “proved undeveloped reserves” category to the “probable undeveloped resources” category included in the Evaluation because those properties are no longer likely to be developed within five years. Our independent consulting petroleum engineering firm calculated our natural gas reserves using volumetric analysis of the reservoir and rate decline analysis for existing producers. The process of estimating proved reserves and future net cash flows is complex involving decisions and assumptions in evaluating the available engineering and geologic data and natural gas prices and the cost to produce these reserves and other factors, many of which are beyond our control. These assumptions include estimates of future natural gas production, commodity prices based on commodity futures price strips, operating and development costs, and a risk-adjusted discount rate of 10%, which is based on an industry standard. As a result, these estimates are imprecise and should be expected to change as future information becomes available. These changes could be significant. As a non-operator of our natural gas properties, we rely on information provided from the operator which is given to our independent consulting petroleum engineering firm for use in the preparation of our reserve estimates. The reserve estimates are reviewed by certain members of our accounting group for accuracy and checked for consistency in its preparation along with validating the assumptions provided by the operator based on actual performance. Additionally, members of management met with the operator periodically to review our properties and discuss performance. In addition, during 2015, we recognized an impairment charge of $3.5 million to write down the carrying value ($8.5 million) of certain plant assets related to certain ammonia production equipment at our Pryor Facility to their estimated fair value of approximately $ 5.0 million. The change of circumstances triggering the review for impairment related primarily to an offer received from a possible buyer on this non-core ammonia production equipment. The estimated fair value was determined based on an offer received from a possible buyer less estimated costs that would be incurred if the equipment is sold (Level 3 inputs). In 2016, this ammonia production equipment was sold to a third party for a minimal gain. 1. Summary of Significant Accounting Policies (continued) Concentration of Credit Risks for Cash and Cash Equivalents and Sales – Financial instruments relating to cash and cash equivalents potentially subject us to concentrations of credit risk. All of these financial instruments were held by financial institutions within the U.S. and none of these financial instruments were in excess of the federally insured limits. Net sales to one customer, Koch Fertilizer LLC, represented approximately 11%, 12% and 7% of our total net sales for 2016, 2015 and 2014, respectively. Net sales to one customer, Covestro AG, represented approximately 13%, 15% and 14% of our total net sales for 2016, 2015 and 2014, respectively. The sales to Covestro are pursuant to an agreement under which one of our subsidiaries operates a nitric plant located within Covestro’s chemical manufacturing complex as discussed in Note 11 – Commitments and Contingencies. This agreement: (a) allows us to pass-through most of the costs of producing the nitric acid that Covestro purchases, including the cost of ammonia; (b) to receive management fees for managing the operations and marketing nitric acid at the Baytown Facility and; (c) to receive a portion of any carbon credits that are sold. Capitalized Software – Intangible and other noncurrent assets include capitalized software that primarily relates to our enterprise resource planning software (“ERP”) for internal use and is stated at cost, net of accumulated amortization. The ERP project was completed during 2016. For 2016 and 2015 our carrying value was $12.9 million and $12.8 million, and accumulated amortization of $3.5 million and $1.8 million, respectively. Capitalized software costs include software purchase costs and internal and external costs for implementing software. For financial reporting purposes, amortization of capitalized software costs is computed using the straight-line method over the estimated useful lives of the software, which is primarily eight years. During 2016, 2015, and 2014, interest cost capitalized in capitalized software was $0.1 million, $0.3 million, and $0.5 million, respectively. Interest costs capitalized ceased during 2016 with the completion of the ERP project. No provision for amortization is made until such time as the relevant assets are placed into service. Amortization expense related to capitalized software was $1.7 million, $1.0 million and $0.3 million for 2016, 2015 and 2014, respectively. Estimated amortization related to capitalized software is $1.7 million for 2017, $1.6 million for 2018 and $1.5 million each of the subsequent three years, 2019 through 2021. Capitalized Interest - Interest cost on borrowings incurred during a significant construction or development project is capitalized. Capitalized interest is added to the associated underlying asset and amortized over the estimated useful lives of the assets. For 2016, 2015 and 2014, interest capitalized amounted to $15.0 million, $30.6 million, $14.1 million, respectively. Accrued Insurance Liabilities - We are self-insured up to certain limits for group health, workers’ compensation and general liability claims. Above these limits, we have commercial stop-loss insurance coverage for our contractual exposure on group health claims and statutory limits under workers’ compensation obligations. We also carry umbrella insurance of $100 million for most general liability and auto liability risks. We have a separate $50 million insurance policy covering pollution liability at our chemical facilities. Additional pollution liability coverage for our other facilities is provided in our general liability and umbrella policies. As it relates to our natural gas properties that we do not operate but only own a working interest, insurance policies are maintained by the operator, which we are responsible for our proportionate share of the costs involved. Our accrued self-insurance liabilities are based on estimates of claims, which include the reported incurred claims amounts plus the reserves established by our insurance adjustors and/or estimates provided by attorneys handling the claims, if any, up to the amount of our self-insurance limits. In addition, our accrued insurance liabilities include estimates of incurred, but not reported, claims based on historical claims experience. The determination of such claims and the appropriateness of the related liability is periodically reviewed and revised, if needed. Changes in these estimated liabilities are charged to operations. Potential legal fees and other directly related costs associated with insurance claims are not accrued but rather are expensed as incurred. Accrued insurance claims are included in accrued and other liabilities. It is reasonably possible that the actual development of claims could be different than our estimates. Executive Benefit Agreements - We are party to certain benefit agreements with certain key current and former executives. Costs associated with these individual benefit agreements are accrued based on the estimated remaining service period when such benefits become probable they will be paid. Total costs accrued equal the present value of specified payments to be made after benefits become payable. Income Taxes – We recognize deferred tax assets and liabilities for the expected future tax consequences attributable to net operating loss (“NOL”) carryforwards, tax credit carryforwards, and differences between the financial statement carrying amounts and the tax basis of our assets and liabilities. We establish valuation allowances if we believe it is more-likely-than-not that some or all of deferred tax assets will not be realized. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. 1. Summary of Significant Accounting Policies (continued) In addition, we do not recognize a tax benefit unless we conclude that it is more-likely-than-not that the benefit will be sustained on audit by the taxing authority based solely on the technical merits of the associated tax position. If the recognition threshold is met, we recognize a tax benefit measured at the largest amount of the tax benefit that, in our judgment, is greater than 50% likely to be realized. We record interest related to unrecognized tax positions in interest expense and penalties in operating other expense. We reduce income tax expense for investment tax credits in the year the credit arises and is earned. Income tax benefits associated with amounts that are deductible for income tax purposes but that do not affect earnings are credited to equity. These benefits are principally generated from exercises of non-qualified stock options and restricted stock. We adopted ASU No. 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes as discussed below in “Recently Issued Accounting Pronouncements”. Contingencies – Certain conditions may exist which may result in a loss, but which will only be resolved when future events occur. We and our legal counsel assess such contingent liabilities, and such assessment inherently involves an exercise of judgment. If the assessment of a contingency indicates that it is probable that a loss has been incurred, we would accrue for such contingent losses when such losses can be reasonably estimated. If the assessment indicates that a potentially material loss contingency is not probable but reasonably possible, or is probable but cannot be estimated, the nature of the contingent liability, together with an estimate of the range of possible loss if determinable and material, would be disclosed. Estimates of potential legal fees and other directly related costs associated with contingencies are not accrued but rather are expensed as incurred. Loss contingency liabilities are included in current and noncurrent accrued and other liabilities and are based on current estimates that may be revised in the near term. In addition, we recognize contingent gains when such gains are realized or realizable and earned. Asset Retirement Obligations - In general, we record the estimated fair value of an asset retirement obligation (“ARO”) associated with tangible long-lived assets in the period it is incurred and when there is sufficient information available to estimate the fair value. An ARO associated with long-lived assets is a legal obligation under existing or enacted law, statute, written or oral contract or legal construction. AROs, which are initially recorded based on estimated discounted cash flows, are accreted to full value over time through charges to cost of sales. In addition, we capitalize the corresponding asset retirement cost as PP&E, which cost is depreciated or depleted over the related asset’s respective useful life. We do not have any assets restricted for the purpose of settling our AROs. Redeemable Preferred Stocks - Our redeemable preferred stocks that are redeemable outside of our control are classified as temporary/mezzanine equity. The redeemable preferred stocks were recorded at fair value upon issuance, net of issuance costs or discounts. In addition, certain embedded features included in the Series E Redeemable Preferred required bifurcation and are classified as derivative liabilities. The carrying values of the redeemable preferred stocks are being increased by periodic accretions (including the amount for dividends earned but not yet declared or paid) 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. See discussion concerning the redemption of a portion of the Series E Redeemable Preferred in Note 11 – Securities Financing including Redeemable Preferred Stocks. Warrants - The common stock warrants issued in conjunction with our redeemable preferred stocks were standalone instruments, indexed to our common stock, and did not include provisions requiring liability classification. As a result, these warrants were classified as equity. The warrants were recorded at fair value upon issuance, net of issuance costs or discounts. See discussion concerning the exercise of the warrants in Note 11 – Securities Financing including Redeemable Preferred Stocks. Equity Awards - Equity award transactions with employees are measured based on the estimated fair value of the equity awards issued. For equity awards with only service conditions that have a graded vesting period, we recognize compensation cost on a straight-line basis over the requisite service period for the entire award. In addition, historically we issue new shares of common stock upon the exercise of stock options but treasury shares may be used. 1. Summary of Significant Accounting Policies (continued) Revenue Recognition and Other Information - We recognize revenue for substantially all of our operations at the time title to the goods transfers to the buyer and there remain no significant future performance obligations by us. All net sales and long-lived assets relate to domestic operations for the periods presented. In addition, net sales to non-U.S. customers were minimal. Recognition of Insurance Recoveries - If an insurance claim relates to a recovery of our losses, we recognize the recovery when it is probable and reasonably estimable. If our insurance claim relates to a contingent gain, we recognize the recovery when it is realized or realizable and earned. Amounts recoverable from our insurance carriers, if any, are included in accounts receivable. An insurance recovery in excess of recoverable costs relating to a business interruption claim, if any, is a reduction to cost of sales. An insurance recovery in excess of recoverable costs relating to a property insurance claim, if any, is included in property insurance recoveries in excess of losses incurred. Cost of Sales - Cost of sales includes materials, labor and overhead costs to manufacture the products sold plus inbound freight, purchasing and receiving costs, inspection costs, internal transfer costs, loading and handling costs, warehousing costs, railcar lease costs and outbound freight. Maintenance, repairs and minor renewal costs relating to Turnarounds are included in cost of sales as they are incurred. Precious metals used as a catalyst and consumed during the manufacturing process are included in cost of sales. Recoveries and gains from precious metals and business interruption insurance claims are reductions to cost of sales. Provisions for (realization of) losses associated with inventory reserves, gains and losses (realized and unrealized) from our commodities and foreign currency futures/forward contracts, and provision for losses, if any, on firm sales commitments are included in cost of sales. Selling, General and Administrative Expense - Selling, general and administrative expense (“SG&A”) includes costs associated with the sales, marketing and administrative functions. Such costs include personnel costs, including benefits, professional fees, office and occupancy costs associated with the sales, marketing and administrative functions. Derivatives, Hedges, Financial Instruments and Carbon Credits - Derivatives are recognized in the balance sheet and are measured at fair value. Changes in fair value of derivatives are recorded in results of operations unless the normal purchase or sale exceptions apply or hedge accounting is elected. The fair value amounts recognized for our derivative contracts executed with the same counterparty under a master netting arrangement may be offset. We have the choice to offset or not, but that choice must be applied consistently. A master netting arrangement exists if the reporting entity has multiple contracts with a single counterparty that are subject to a contractual agreement that provides for the net settlement of all contracts through a single payment in a single currency in the event of default on or termination of any one contract. Offsetting the fair values recognized for the derivative contracts outstanding with a single counterparty results in the net fair value of the transactions being reported as an asset or a liability in the balance sheet. We have chosen to present the fair values of our derivative contracts under master netting agreements using a gross fair value presentation as there were no derivatives with fair values that were eligible to be offset as of December 31, 2016 and 2015. The assets for climate reserve tonnes (“carbon credits”) are recognized in the balance sheet and are measured at fair value. Changes in fair value of carbon credits are recorded in results of operations. The liabilities for contractual obligations associated with carbon credits are recognized in the balance sheet and are measured at fair value unless we enter into a firm sales commitment to sell the associated carbon credits. When we enter into a firm sales commitment, the sales price, pursuant to the terms of the firm sales commitment, establishes the amount of the liability for the contractual obligation. Changes in fair value of contractual obligations associated with carbon credits are recorded in results of operations. Income (Loss) per Common Share - Net income (loss) attributable to common stockholders is computed by adjusting net income (loss) by the amount of dividends and dividend requirements on preferred stocks and the accretion of redeemable preferred stocks, if applicable. Basic loss per common share is computed by dividing net loss attributable to common stockholders by the weighted average number of common shares outstanding, 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. 1. Summary of Significant Accounting Policies (continued) 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. Segment Information - With the sale of our Climate Control Business during July 2016, we operate in one principal business segment – our chemical business. 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 preliminary 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 our working interest in natural gas properties, performing various services, and rental income. A contract review process is being implemented to obtain and review our new or amended contracts for analysis for adopting this ASU. We will begin to focus on developing a preliminary 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. Although we anticipate that upon adoption of this new ASU, the timing of revenue recognition 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. The guidance requires an entity to measure inventory at the lower of cost or net realizable value, which is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation, rather than the lower of cost or market in the previous guidance. This amendment applies to inventory that is measured using first-in, first-out (FIFO). This amendment is effective for public entities for fiscal years beginning after December 15, 2016, including interim periods within those years. A reporting entity should apply the amendments prospectively with earlier application permitted as of the beginning of an interim or annual reporting period. We do not expect a significant effect from adopting this ASU. In November 2015, the FASB issued ASU No. 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes, which simplifies the presentation of deferred income taxes by eliminating the need for entities to separate deferred income tax liabilities and assets into current and noncurrent amounts in a classified statement of financial position. As a result, all deferred taxes are classified as noncurrent as of December 31, 2016. We adopted this ASU on October 1, 2016 and applied the guidance prospectively to all deferred income taxes. Accordingly, prior period balances have not been reclassified. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which creates Topic 842, Leases, and supersedes the lease requirements in Topic 840, Leases. Topic 842 specifies the accounting for leases. The objective of Topic 842 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. Extensive quantitative and qualitative disclosures, including significant judgments made by management, will be required to provide greater insight into the extent of revenue and expense recognized and expected to be recognized from existing contracts. This ASU is effective for us on January 1, 2019 but early adoption is permitted. This ASU must be adopted using a modified retrospective transition, and provides for certain practical expedients. Transition will require application of the new guidance at the beginning of the earliest comparative period presented. Although we currently have a relative small number of leases, we are evaluating the effect of this guidance on our consolidated financial statements and related disclosures and if we plan to early adopt. 1. Summary of Significant Accounting Policies (continued) In March 2016, the FASB issued ASU No. 2016-09, Compensation—Stock Compensation (Topic 718): Improvements to Employee Share Based Payment Accounting, which amends ASC Topic 718, Compensation - Stock Compensation. ASU 2016-09 includes provisions intended to simplify various aspects related to how share based payments are accounted for and presented in the financial statements. The new guidance among other requirements will require all of the tax effects related to share based payments at settlement (or expiration) to be recorded through the income statement. Currently, tax benefits in excess of compensation cost ("windfalls") are recorded in equity, and tax deficiencies ("shortfalls") are recorded in equity to the extent of previous windfalls, and then to the income statement. This change is required to be applied prospectively to all excess tax benefits and tax deficiencies resulting from settlements after the date of adoption of the ASU 2016-09. Under the new guidance, the windfall tax benefit will be recorded when it arises, subject to normal valuation allowance considerations. This change is required to be applied on a modified retrospective basis, with a cumulative effect adjustment to opening retained earnings. 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 the current requirement to present windfall tax benefits as an inflow from financing activities and an outflow from operating activities. Either prospective or retrospective transition of this provision is permitted. ASU 2016-09 is effective for annual reporting periods beginning after December 15, 2016, and interim periods within that reporting period. The Company will prospectively adopt this standard in first quarter of 2017 and expects a cumulative effect of approximately $1.1 million to be recorded as a deferred tax asset with the offset in retained earnings. Going forward, tax benefits in excess of compensation cost previously recorded in equity will be recorded within the income statement and all tax related cash flows resulting from share based payments will be recorded as an operating activity within the statement of cash flows. 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. This ASU makes eight targeted changes to how cash receipts and cash payments are presented and classified in the statement of cash flows. This ASU is effective for us on January 1, 2018 and adoption will be applied on retrospective basis unless it is impracticable to apply, in which case we would be required to apply the ASU prospectively as of the earliest date practicable. We are currently evaluating the effect of our pending adoption of this ASU on our consolidated financial statements and related disclosures. 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. The amendments in this ASU revise the guidance in Topic 230, Statement of Cash Flows, to require cash and cash equivalents to include restricted cash (and 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. Early adoption is allowed. If an entity adopts early in an interim period, an entity must make any adjustments required to comply with the ASU as of the beginning of the annual period that includes the interim period. We are currently evaluating the effect of our pending adoption of this ASU on our consolidated financial statements and related disclosures.

Discontinued Operations And Disposal Groups [Abstract]

Discontinued Operations

2. Discontinued Operations

On July 1, 2016, LSB completed the sale of the Climate Control Group to NIBE pursuant to the terms of the Stock Purchase Agreement which, among other things, Consolidated sold all of the stock of the Climate Control Group for an aggregate purchase price of approximately $364 million, before the adjustments as set forth in the Stock Purchase Agreement. As a result, we recognized a pre-tax gain on the sale of $282 million. Additionally, pursuant to the Stock Purchase Agreement, we paid approximately $2.6 million of the cost of a representation and warranty insurance policy and excess directors’ and officers’ insurance policy and agreed to have a certain portion of the purchase price proceeds deposited in both an indemnity escrow and a working capital adjustment escrow account (collectively, the “Escrow Accounts”). 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 for up to 18 months at an approximate total cost of $2.3 million. At December 31, 2016, our accounts receivable included approximately $2.7 million relating to the sale of our Climate Control Business representing an indemnity escrow balance. Additionally, our current and noncurrent accrued and other liabilities include approximately $5.5 million relating primarily to estimated contingent liabilities, costs associated with the TSA and severance agreements associated with the sale of the Climate Control Business.

Asset Retirement Obligations	8. Asset Retirement Obligations Currently, we have various legal requirements related to operations at our chemical facilities, including the disposal of wastewater 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 AROs. 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. In addition, we own working interests in certain natural gas properties. We recognized AROs associated with the obligation to plug and abandon wells when the natural gas reserves in the wells are depleted. At December 31, 2016 and 2015, our accrued liability for AROs was $546,000 and $281,000, respectively.

(B) In 2013, LSB sold $425 million aggregate principal amount of the 7.75% Senior Secured Notes due 2019 in a private transaction to qualified institutional buyers under Rule 144A and, outside of the United States, pursuant to Regulation S of the Securities Act of 1933 (as amended, the “Securities Act”).

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

9. Long-Term Debt (continued)

In September 2016, we completed the consent solicitation initiated in August 2016 (the “Consent Solicitation”) to effect certain amendments to the Indenture (the “Indenture Amendments”), dated as of August 7, 2013 (the “Original 7.75% Indenture”), pursuant to which we issued the $425 million 7.75% Senior Secured Notes due 2019 (the “Senior Secured Notes”). In connection with the Consent Solicitation, we entered into the First Supplemental Indenture, dated as of September 7, 2016 (the “Supplemental Indenture”) to the Original 7.75% Indenture. Among other things, the Amendments contained in the Supplemental Indenture allowed us to redeem a portion of the Series E Redeemable Preferred as discussed in Note 13 and allowed us to:

•

redeem all outstanding $50 million in aggregate principal amount of our 12% Senior Secured Notes due 2019 (the “12% Senior Secured Notes”), at a redemption price of 106% (original redemption price) of the principal amount thereof plus accrued and unpaid interest to the redemption date (the “12% Notes Redemption”), with the net proceeds of the sale of the Climate Control Business and

•

redeem $50 million in aggregate principal amount of the Senior Secured Notes, at a redemption price of 103.875% (original redemption price) of the principal amount thereof plus accrued and unpaid interest to the redemption date, with the net proceeds of the sale of the Climate Control Business (the “7.75% Notes Redemption”).

During October 2016, we made payments totaling $106.9 million related to the above redemptions resulting in the recognition of a loss on extinguishment of debt of approximately $8.7 million.

In addition, we agreed to prohibitions on our ability to incur future pari passu indebtedness in excess of $25 million (decreased from $50 million) in aggregate principal amount at any time outstanding using the “general debt” basket and the “general liens” basket under the Supplemental Indenture. Pursuant to the Supplemental Indenture, the interest rate applicable to all Senior Secured Notes outstanding after the consummation of the 7.75% Notes Redemption, with retroactive effect to August 1, 2016, was automatically increased to 8.5% per annum. As a result of the interest rate increase, we recognized an additional $1.2 million of interest expense during 2016.

For financial reporting purposes, the above transaction was a non-substantial debt modification. As a result, the consent fee of approximately $5.4 million (equal to $13.25 per $1,000 principal amount of Senior Secured Notes for which a consent had been validly delivered) paid to the holders of the Senior Secured Notes was deferred and included in debt issuance costs and is being amortized over the remaining term of the Senior Secured Notes. In addition, we incurred other fees of approximately $1.4 million for services performed by third parties, which fees were expensed and included in interest expense in 2016.

The Senior Secured Notes are general senior secured obligations of LSB. The Senior Secured Notes are jointly and severally and fully and unconditionally guaranteed by all of LSB’s current wholly-owned subsidiaries, with all of the guarantees, except one, being senior secured guarantees and one being a senior unsecured guarantee. The Senior Secured Notes rank equally in right of payment to all of LSB and the guarantors’ existing and future senior secured debt, including the Amended Working Capital Revolver Loan discussed above, and are senior in right of payment to all of LSB and the guarantors’ future subordinated indebtedness. LSB does not have independent assets or operations.

Those subsidiaries that provided guarantees of the Senior Secured Notes will be released from such guarantees upon the occurrence of certain events, including the following:

•

the designation of such guarantor as an unrestricted subsidiary;

•

the release or discharge of any guarantee or indebtedness that resulted in the creation of the guarantee of the Senior Secured Notes by such guarantor;

•

the sale or other disposition, including by way of merger or otherwise, of its capital stock or of all or substantially all of the assets, of such guarantor (see Note – 2 Discontinued Operations); or

•

LSB’s exercise of its legal defeasance option or its covenant defeasance option as described in the Indenture with LSB’s obligations under the Indenture discharged in accordance with the Indenture.

9. Long-Term Debt (continued)

The Senior Secured Notes are effectively senior to all existing and future unsecured debt of LSB and the guarantors to the extent of the value of the property and assets subject to liens (“Collateral”) and are effectively senior to all existing and future obligations under the Amended Working Capital Revolver Loan and other debt to the extent of the value of the certain collateral (“Priority Collateral”).

The Senior Secured Notes are secured on a first-priority basis by the Priority Collateral owned by LSB and the guarantors (other than the one unsecured guarantor) in each case subject to certain liens permitted under the Indenture. The Senior Secured Notes will be equal in priority as to the Priority Collateral owned by LSB and the guarantor with respect to any obligations under any equally ranked lien obligations subsequently incurred. At December 31, 2016, the carrying value of the assets secured on a first-priority basis was approximately $1.1 billion and the carrying value of the assets secured on a second-priority basis was approximately $60.4 million.

The Senior Secured Notes are subordinated to all of LSB and the guarantors’ existing and future obligations under the Amended Working Capital Revolver Loan and other debt to the extent of the value of the certain collateral securing such debt and to any of LSB and the guarantors’ existing and future indebtedness that is secured by liens that are not part of the Collateral. The Senior Secured Notes will be structurally subordinated to all of the existing and future indebtedness, preferred stock obligations and other liabilities, including trade payables, of our subsidiaries that do not guarantee the Senior Secured Notes in the future.

LSB may redeem the Senior Secured Notes at its option, in whole or in part, upon not less than 30 nor more than 60 days’ notice, at the following redemption prices (expressed as percentages of the principal amount thereof), plus accrued and unpaid interest to the redemption date (subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date), if redeemed during the twelve-month period commencing on August 1st of the year set forth below:

Year	Senior Secured Notes
Currently		103.875	%
2017		101.938	%
2018 and thereafter		100.000	%

Upon the occurrence of a change of control, as defined in the Indenture, each holder of the Senior Secured Notes will have the right to require that LSB purchase all or a portion of such holder’s notes at a purchase price equal to 101% of the principal amount thereof plus accrued and unpaid interest, if any, to the date of purchase (subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date).

The Indenture contains covenants that, among other things, limit LSB’s ability, with certain exceptions and as defined in the Indenture, to:

•

incur additional indebtedness;

•

pay dividends;

•

repurchase LSB common and preferred stocks;

•

make investments;

•

repay certain indebtedness;

•

create liens on, sell or otherwise dispose of our assets;

•

engage in mergers, consolidations or other forms of recapitalization;

•

engage in sale-leaseback transactions; or

•

engage in certain affiliate transactions.

(C) On February 1, 2013, Zena Energy L.L.C. (“Zena”), one of our subsidiaries, entered into a loan (the “Secured Promissory Note”) with a lender in the original principal amount of $35 million. The Secured Promissory Note followed the original acquisition by Zena of working interests (“Working Interests”) in certain natural gas properties. Effective April 1, 2016, Zena entered into the second amended and restated note (the “Amended Note”) with the original lender. Principal and interest are payable in 20 monthly installments beginning with the May 1^st installment. Interest is based on the LIBOR rate plus 300 basis points and the terms of which were not changed by this amendment. The Amended Note matures on December 1, 2017. The Amended Note continues to be secured by the Working Interests and related properties and proceeds and is guaranteed by LSB.

(D) On February 5, 2016, El Dorado Chemical Company (“EDC”), one of our subsidiaries, entered into a secured promissory note (the “Secured Promissory Note due 2019”) for an original principal amount of $10 million that matures on June 29, 2019. Principal and interest are payable in 40 equal monthly installments with a final balloon payment of approximately $6.7 million. The Secured Promissory Note due 2019 is secured by the cogeneration facility equipment and is guaranteed by LSB.

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

(F) On September 16, 2015, El Dorado Ammonia L.L.C. (“EDA”), one of our subsidiaries, entered into a secured promissory note (the “Secured Promissory Note due 2023”) for the construction financing of an ammonia storage tank and related systems with an initial funding received of $15 million and a maximum principal note amount of $19.8 million. On May 13, 2016 (the “Loan Conversion Date”), the remainder of the funding of $4.8 million was drawn and the outstanding principal balance of $19.8 million was converted to a seven year secured term loan requiring 83 equal monthly principal and interest payments with a final balloon payment of approximately $6.1 million. This Note bears interest at a rate that is based on the monthly LIBOR rate plus a base rate for a total of 4.87% and matures in May 2023. The Secured Promissory Note is secured by the ammonia storage tank and related systems and is guaranteed by LSB.

Provisions (benefit) for income taxes	$	(41,956	)	$	(32,520	)	$	4,251

The current provision for federal income taxes shown above includes regular federal income tax after the consideration of permanent and temporary differences between income for GAAP and tax purposes. The current provision for state income taxes includes regular state income tax and provisions for uncertain income tax positions

The deferred tax provision (benefit) results from the recognition of changes in our prior year deferred tax assets and liabilities, and the utilization of state NOL carryforwards and other temporary differences. We reduce income tax expense for tax credits in the year they arise and are earned. At December 31, 2016, our gross amount of the investment tax credits available to offset state income taxes was minimal. These investment tax credits do not expire and carryforward indefinitely. The gross amount of federal tax credits was $8.1 million. These credits carryforward for 20 years and begin expiring in 2034.

We utilized approximately $0.4 million, $9.6 million and $5.9 million of state NOL carryforwards to reduce tax liabilities in 2016, 2015 and 2014, respectively. At December 31, 2016, we have remaining federal and state tax NOL carryforwards of $390.1 million and $326.5 million, respectively, which amounts exclude the NOL carryforwards that are related to unrecognized tax benefits and stock compensation that have not been recognized in accordance with GAAP. The federal NOL carryforwards begin expiring in 2033 and the state NOL carryforwards begin expiring in 2016.

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

We considered both positive and negative evidence in our determination of the need for valuation allowances for the deferred tax assets associated with federal and state NOLs and federal credits and in conjunction with the IRC Section 382 limitation and determined that it was more-likely-than-not that the federal NOL and credits would be utilized before expiration. For 2016, 2015 and 2014, we determined it was more-likely-than-not that approximately $312.3 million, $34.5 million and $8.1 million, respectively, of the state NOL carryforwards would not be able to be utilized before expiration and a valuation allowance was maintained for the deferred tax assets associated with these state NOL carryforwards, net of federal benefit of approximately $13.1 million and $1.2 million in 2016 and 2015, respectively.

When non-qualified stock options (“NSOs”) are exercised, the grantor of the options is permitted to deduct the spread between the fair market value of the stock issued and the exercise price of the NSOs as compensation expense in determining taxable income. Income tax benefits related to stock-based compensation deductions in excess of the compensation expense recorded for financial reporting purposes are not recognized in earnings as a reduction of income tax expense for financial reporting purposes. As a result, the stock-based compensation deduction recognized in our income tax return will exceed the stock-based compensation expense recognized in earnings. In 2016, there is no excess tax benefit realized (i.e., the resulting reduction in the current tax liability) related to an excess stock-based compensation tax deduction. The excess stock-based compensation tax deduction was $0.6 million in 2015 and none in 2014. In 2015, the deduction was included in the net change in capital in excess of par value rather than an increase in the benefit for income taxes.

10. Income Taxes (continued)

In addition, if the grantor of NSOs will not currently reduce its tax liability from the excess tax benefit deduction taken at the time of the taxable event (option exercised) because it has a NOL carryforward that is increased by the excess tax benefit, then the tax benefit should not be recognized until the deduction actually reduces current taxes payable. The amounts included in the federal and state NOL carryforwards but not reflected in deferred tax assets at December 31, 2016 totaled $3 million and $2.9 million, respectively. At December 31, 2016, there is no additional unrecognized federal or state tax benefit resulting from the exercise of NSOs. However, at December 31, 2015 and 2014, we had $1.2 million and $1.1 million, respectively of unrecognized federal and state tax benefits resulting from the exercise of NSOs.

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

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

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

	2016			2015			2014
	(In Thousands)
Balance at beginning of year	$	259		$	657		$	2,409
Additions based on tax positions related to the current year		454			70			45

Settlements		—			(38	)		(753	)
Balance at end of year	$	657		$	259		$	657

We expect that the amount of unrecognized tax benefits may change as the result of ongoing operations, the outcomes of audits, and the expiration of statute of limitations. This change is not expected to have a significant effect on our results of operations or financial condition. For 2016, 2015, and 2014, there would be no effect on the effective tax rate from unrecognized tax benefits, if recognized.

We record interest related to unrecognized tax positions in interest expense and penalties in operating other expense. During 2016, we recognized a minimal amount of interest and penalties associated with unrecognized tax benefits. At December 31, 2016, 2015 and 2014, the amounts accrued for interest and penalties were minimal. During 2014, we recognized a recovery of $522,000 in interest expense and penalties associated with the reduction of unrecognized tax positions (minimal in 2015 and 2016).

LSB and certain of its subsidiaries file income tax returns in the U.S. federal jurisdiction and various state jurisdictions. With few exceptions, the 2013-2015 years remain open for all purposes of examination by the U.S. Internal Revenue Service (“IRS”) and other major tax jurisdictions. During 2014, we settled the examination with the IRS for the tax years 2008-2010 with no material changes to our financial position, results of operations and cash flow.

Renewal options are available under certain of the lease agreements for various periods at approximately the existing annual rental amounts.

11. Commitments and Contingencies (continued)

Purchase and Sales Commitments - We have the following significant purchase and sales commitments.

Covestro agreement – El Dorado Nitric Company and its subsidiaries (“EDN”) and EDC, are party to an agreement (the “Covestro Agreement”) with Covestro AG, (“Covestro”). EDN operates the nitric acid plant (the “Baytown Facility”) located within Covestro’s chemical manufacturing complex. Under the terms of the Covestro Agreement, Covestro purchases from EDN all of Covestro’s requirements for nitric acid for use in Covestro’s chemical manufacturing complex located in Baytown, Texas that provides a pass-through of certain costs plus a profit. In addition, EDN is responsible for the maintenance and operation of the Baytown Facility. If there is a change in control of EDN, Covestro has the right to terminate the Covestro Agreement upon payment of certain fees to EDN. The Covestro Agreement expires in June 2021, with options for renewal.

UAN supply agreement – In March 2016, PCC and Coffeyville Resources Nitrogen Fertilizers, LLC (“CVR”) entered into a UAN Purchase and Sale Agreement, which became effective June 1, 2016. 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 pursuit to the terms of the agreement may immediately sell such unpurchased product to a third-party without restriction. The initial term of the agreement is for three years with automatic renewals for one or more additional one-year terms unless terminated by either party by delivering a notice of termination at least twelve months prior to the end of term in effect. 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 CVR Purchase 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 – On November 2, 2015, EDC and Koch Fertilizer, LLC (“Koch Fertilizer”) entered into an ammonia purchase and sale agreement under which Koch Fertilizer agrees to purchase, with minimum purchase requirements, the ammonia that (a) will be produced at the El Dorado Facility and (b) that is in excess of El Dorado’s needs. The initial term of the agreement is for three years, and automatically continues for one or more additional one-year terms unless terminated by either party by delivering a notice of termination at least nine months prior to the end of term in effect.

Natural gas gathering agreement – Zena owns an approximately 12% working interest in certain natural gas properties but is not the operator of these properties. The operator of the natural gas wells developed on these properties has contractually agreed to deliver a minimum daily quantity of natural gas to a certain gathering and pipeline system through December 2026 to ensure capacity availability on that system. This gathering agreement effectively requires a daily minimum demand charge. As a result, Zena’s proportionate share of the annual minimum demand charges is approximately $1.8 million for each of the next five years and approximately $2.1 million thereafter for a total of approximately $11 million.

Other purchase and sales commitments - See Note 12 – Derivatives, Hedges, Financial Instruments and Carbon Credits for our commitments relating to derivative contracts and carbon credits at December 31, 2016. During 2016, certain subsidiaries entered into 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, 2016, our natural gas contracts, which are exempt from mark-to-market accounting, included the volume purchase commitments with fixed costs of approximately 2.4 million MMBtus of natural gas. These contracts extend through March 2017 at a weighted-average cost of $3.20 per MMBtu ($7.8 million) and a weighted-average market value of $3.64 per MMBtu ($8.9 million). In addition, we had standby letters of credit outstanding of approximately $2.8 million at December 31, 2016. We also had deposits from customers of $2.5 million for forward sales commitments at December 31, 2016.

Termination of UAN Supply Agreement - Our subsidiary, PCC, was party to a contract with Koch Nitrogen Company, LLC (“Koch Nitrogen”) under which Koch Nitrogen agrees to purchase and distribute at market prices substantially all of the UAN produced at the Pryor Facility through June 30, 2016 (the “Koch Purchase Agreement”). On March 1, 2016, PCC provided notice of termination under the Koch Purchase Agreement, terminating the agreement effective May 31, 2016.

11. Commitments and Contingencies (continued)

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, 2016, 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 2017.

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 $13.7 million at December 31, 2016.

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. 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. We do not operate the natural gas wells where we own a working interest and compliance with Environmental and Health Laws is controlled by others. We are responsible for our working interest proportionate share of the costs involved. As of December 31, 2016, our accrued liabilities for environmental matters totaled $257,000 relating primarily to the matters discussed below. It is reasonably possible that a change in the estimate of our liability could occur in the near term. Also, see discussion in Note 8 – Asset Retirement Obligations.

11. Commitments and Contingencies (continued)

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 permit to inject wastewater into an on-site underground injection well through 2018. The Oklahoma Department of Environmental Quality (“ODEQ”) has indicated that the permit may not be renewed following its expiration, and PCC may have to find an alternative means of waste water disposal after the permit expires. PCC has engaged in ongoing discussions both internally and with the ODEQ 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. 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. We believe that the issue with the storm-water runoff should be resolved if and when the ADEQ issues a new NPDES discharge water permit, which we have been advised that the ADEQ is currently processing.

During 2012, EDC paid a penalty of $100,000 to settle an administrative complaint issued by the EPA, and thereafter handled by the U.S. Department of Justice (“DOJ”), relating to certain alleged violations 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 December 31, 2016.

In addition, the El Dorado Facility is currently operating under a consent administrative order (the “CAO”) that recognizes the presence of nitrate contamination in the shallow groundwater. The 2006 CAO required EDC to continue semiannual groundwater monitoring, to continue operation of a groundwater recovery system and to submit a human health and ecological risk assessment to the ADEQ relating to the El Dorado Facility. The risk assessment was submitted in August 2007. In February 2015, the ADEQ stated that El Dorado Chemical was meeting the requirements of the CAO and should continue semi-annual monitoring. The final remedy for shallow groundwater contamination, should any remediation be required, will be selected pursuant to a new consent administrative order and based upon the risk assessment. The cost of any additional remediation that may be required will be determined based on the results of the investigation and risk assessment, of which cost (or range of costs) cannot currently be reasonably estimated. Therefore, no liability has been established at December 31, 2016, in connection with this matter.

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 December 31, 2016, we are not aware of any recommendations made or to be made by the ODEQ with respect to legal action to be taken or recommended as a result of this ongoing investigation.

11. Commitments and Contingencies (continued)

3. Other Environmental Matters

In November 2006, EDC entered into a Consent Administrative Order (“CAO”) with the ADEQ to address nitrates in shallow groundwater. The CAO requires 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. EDC’s risk assessment and the remedial action plan, initially submitted to the ADEQ in 2007, recommended monitored natural attenuation. The ADEQ’s review of the EDC proposed remedy is ongoing. Under the CAO, the ADEQ may require additional wells be added to the program or may allow EDC to remove wells from the program. At this time, the duration and cost (or range of costs) of the ground water monitoring program or the necessity for any additional remediation cannot be reasonably estimated.

During 2014, the Cherokee Facility received Notice of Violation (“NOV”) from the EPA as a result of a 2013 risk management inspection at the facility. The NOV listed eleven alleged violations. We reached a settlement of the NOV in March 2016 whereby we agreed to pay a penalty in the form of providing approximately $100,000 to purchase emergency response equipment for local first responders plus a civil penalty to the EPA of approximately $26,000, which both penalties have been paid.

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

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

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

11. Commitments and Contingencies (continued)

Subsequently, we and EDC have entered into confidential settlement agreements 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. 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 December 31, 2016, no liability reserve has been established in connection with this matter, except for the unpaid portion of a settlement agreement 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. (“BAE”), et al. vs. El Dorado Chemical Company, in the United States District Court, Western District of Arkansas, for an alleged breach of a supply agreement to provide BAE certain products. It is EDC’s position, among other things, that its inability to deliver to BAE was due to a force majeure event caused by a fire and explosion at EDC’s nitric acid plant, and that a force majeure clause in the supply agreement therefore excuses EDC’s performance under the supply agreement. BAE’s pre-litigation demand indicated a claim of approximately $18 million. EDC intends to vigorously defend this matter. The cost (or range of costs), if any, EDC would incur relating to this matter cannot currently be reasonably estimated. Therefore, no liability has been established at December 31, 2016.

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

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., where in Global seeks damages under breach of contract and other claims. We have requested indemnifications from Leidos under the terms of our contracts and we intend to vigorously defend against the allegation made by Global. No liability has been established in connection with the remaining $5 million claim. In addition, LSB and EDA intend to pursue recovery of any damage or loss caused by Global’s work performed at our El Dorado Facility.

We are also involved in various other claims and legal actions. 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.

Derivatives, Hedges, Financial Instruments and Carbon Credits

12. Derivatives, Hedges, Financial Instruments and Carbon Credits

Periodically, we have three classes of contracts that are accounted for on a fair value basis, which are commodities futures/forward contracts (“commodities contracts”), foreign exchange contracts and interest rate contracts as discussed below. All of these contracts are used as economic hedges for risk management purposes but are not designated as hedging instruments. In addition, as discussed below, we are issued climate reserve tonnes (“carbon credits”), of which a certain portion of the carbon credits are to be sold and the proceeds given to Covestro. The assets for carbon credits are accounted for on a fair value basis as discussed below. Also, the contractual obligations to give the related proceeds to Covestro are accounted for on a fair value basis (as discussed below) unless we enter into a firm sales commitment to sell the carbon credits as discussed in Note 1 – Summary of Significant Accounting Policies. In addition, certain embedded features (“embedded derivative”) included in the Series E Redeemable Preferred required bifurcation and are discussed Note 13. The valuations of these assets and liabilities were determined based on quoted market prices or, in instances where market quotes are not available, other valuation techniques or models used to estimate fair values.

Level 1 - The valuations of contracts classified as Level 1 are based on quoted prices in active markets for identical contracts.

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 December 31, 2016, the valuations of contracts classified as Level 2 related to a foreign exchange contract. At December 31, 2015, the valuations of contracts classified as Level 2 related to certain futures/forward natural gas contracts, a foreign exchange contract, an interest rate swap contract and an embedded derivative. For the natural gas contracts, these contracts were valued using the prices pursuant to the terms of the contracts and using market information for futures/forward natural gas prices. For foreign exchange contracts, these contracts are valued using the foreign currency exchange rates pursuant to the terms of the contract and using market information for foreign currency exchange rates. The valuation inputs included the total contractual exchange rate of 1.12 and the total estimated market exchange rate of 1.05 (U.S. Dollar/Euro). For interest rate swap contracts, we utilized valuation software and market data from a third-party provider. These contracts were valued using a discounted cash flow model that calculates the present value of future cash flows pursuant to the terms of the contracts and using market information for forward interest-rate yield curves. At December 31, 2015, the valuation inputs included the contractual weighted-average pay rate of 3.23% and the estimated market weighted-average receive rate of 0.61%. The interest rate swap contract matured in 2016. For the embedded derivative at December 31, 2015, the derivative was valued using the underlying number of shares as defined in the terms of the Series E Redeemable Preferred and the market price of our common stock. No valuation input adjustments were considered necessary relating to nonperformance risk for the contracts as discussed above.

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 December 31, 2016, we did not have any carbon credits or related contractual obligations associated with carbon credits. At December 31, 2015, the valuation ($2.35 per carbon credit, none for 2016) of the carbon credits and the contractual obligations associated with these carbon credits are classified as Level 3 and are based on the most recent sales transaction and reevaluated for market changes, if any, and on the range of ask/bid prices obtained from a broker adjusted for minimal market volume activity, respectively. The valuations are using undiscounted cash flows based on management’s assumption that the carbon credits would be sold and the associated contractual obligations would be extinguished in the near term. At December 31, 2016, the valuation of the embedded derivative is 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 carbon credits or the instruments discussed above.

Commodities Contracts

Raw materials for use in our manufacturing processes include natural gas. As part of our raw material price risk management, we periodically enter into futures/forward contracts for these materials, which contracts may be required to be accounted for on a mark-to-market basis. At December 31, 2016, we did not have any futures/forward natural gas contracts subject to mark-to-market accounting. At December 31, 2015, our futures/forward natural gas contracts included 1,820,000 MMBtu of natural gas, extend through December 2016 (includes contractual costs indexed to future NYMEX prices) at a weighted-average cost of $2.35 per MMBtu. The cash flows relating to these contracts are included in cash flows from continuing operating activities.

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

Foreign Exchange Contracts

One of our subsidiaries purchases industrial machinery and related components from vendors outside of the U.S. As part of our foreign currency risk management, we periodically enter into foreign exchange contracts, which set the U.S. Dollar/Euro exchange rates. At December 31, 2016 and 2015, our foreign exchange contract was for the receipt of approximately 16,000 and 280,000 Euros, respectively, through February 2017 at the contractual exchange rate of 1.12 (U.S. Dollar/Euro). These contracts are free-standing derivatives and are accounted for on a mark-to-market basis. The cash flows relating to these contracts are included in cash flows from continuing operating activities.

Interest Rate Contracts

In February 2011, we entered into an interest rate swap at no cost, which set a fixed three-month LIBOR rate of 3.23% on a declining balance (from $23.8 million to $18.8 million) for the period beginning in April 2012 and ended in March 2016. This contract was a free-standing derivative and was accounted for on a mark-to-market basis. During each of the three years ended December 31, 2016, no cash flows occurred relating to the purchase or sale of interest rate contracts. The cash flows associated with the interest rate swap payments were included in cash flows from continuing operating activities.

Carbon Credits and Associated Contractual Obligation

Periodically, we are issued carbon credits by the Climate Action Reserve in relation to a greenhouse gas reduction project (“Project”) performed at the Baytown Facility. Pursuant to the terms of the agreement with Covestro, a certain portion of the carbon credits are to be used to recover the costs of the Project, and any balance thereafter to be allocated between Covestro and EDN. We have no obligation to reimburse Covestro for their costs associated with the Project, except through the transfer or sale of the carbon credits when such credits are issued to us. The assets for carbon credits are accounted for on a fair value basis and the contractual obligations associated with these carbon credits are also accounted for on a fair value basis (unless we enter into a sales commitment to sell the carbon credits). At December 31, 2015, we had approximately 495,000 carbon credits (none at December 31, 2016), all of which were subject to contractual obligations. The cash flows associated with the carbon credits and the associated contractual obligations are included in cash flows from continuing investing activities.

Embedded Derivative

The embedded derivatives relating to the redemption of the Series E Redeemable Preferred, which includes certain contingent redemption features and the participation rights value as discussed in Note 13, has been bifurcated from the Series E Redeemable Preferred and recorded as a liability. As the result of the Indenture Amendments in connection with the Consent Solicitation relating to the Senior Secured Notes as discussed in Note 9, including the redemption of the portion of Series E Redeemable Preferred discussed in Notes 9 and 13, we estimate that the contingent redemption feature has no fair value at December 31, 2016 based on low probability that the remaining shares of Series E Redeemable Preferred would be redeemed prior to August 2, 2019. At December 31, 2016 and 2015, the fair value of the participation rights was based on the equivalent of 303,646 and 456,225 shares, respectively of our common stock at $8.42 and $7.25 per share, respectively.

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

The following details our assets and liabilities associated with continuing operations that are measured at fair value on a recurring basis at December 31, 2016 and 2015:

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

None of our assets or liabilities measured at fair value on a recurring basis transferred between Level 1 and Level 2 classifications for the periods presented below except for certain futures/forward natural gas contracts during 2014. As discussed above under “Embedded Derivative”, as the result of entering into the Stock Purchase Agreement relating to the subsequent sale of the Climate Control Business, the valuation of the embedded derivative transferred from Level 2 to Level 3 as the result of the changes in probability 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):

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

At December 31, 2016 and 2015, 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.

	2016				2015

(1)	Based on a quoted price of 94.88 at December 31, 2016 and 83.65 at December 31, 2015.

The Senior Secured Notes valuations are classified as Level 2. The valuations of our other long-term debt agreements are classified as Level 3 and are based on valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement. The fair value measurements of our other long-term debt agreements are valued using a discounted cash flow model that calculates the present value of future cash flows pursuant to the terms of the debt agreements and applies estimated current market interest rates. The estimated current market interest rates are based primarily on interest rates currently being offered on borrowings of similar amounts and terms. In addition, no valuation input adjustments were considered necessary relating to nonperformance risk for our debt agreements. The fair value of financial instruments is not indicative of the overall fair value of our assets and liabilities since financial instruments do not include all assets, including intangibles, and all liabilities.

Also, see discussions concerning the utilization of fair value in conjunction with the evaluation of goodwill for impairment under Note 1 – Summary of Significant Accounting Policies and certain assets and liabilities initially accounted for on a fair value basis under Note 8 – Asset Retirement Obligations.

- Definition

The entire disclosure for derivative instruments and hedging activities including, but not limited to, risk management strategies, non-hedging derivative instruments, assets, liabilities, revenue and expenses, and methodologies and assumptions used in determining the amounts.

Securities Financing Including Redeemable Preferred Stocks

12 Months Ended

Dec. 31, 2016

Equity [Abstract]

Securities Financing Including Redeemable Preferred Stocks

13. Securities Financing Including Redeemable Preferred Stocks

Securities Purchase Agreement Including Redeemable Preferred Stocks

In December 2015 and pursuant to a securities purchase agreement between LSB and LSB Funding LLC (the “Purchaser”) and Security Benefit Corporation, a Kansas corporation, both of which are unrelated third parties, LSB sold to the Purchaser:

•

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

•

warrants to purchase 4,103,746 shares of common stock, par value $0.10 (the “Warrants”), and

•

one share of Series F Redeemable Class C preferred stock (the “Series F Redeemable Preferred”).

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

•

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

•

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

•

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

13. Securities Financing Including Redeemable Preferred Stocks (continued)

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

Series E Redeemable Preferred

The Series E COD authorizes 210,000 shares of Series E Redeemable Preferred. On September 19, 2016, we redeemed 70,232 shares of the Series E Redeemable Preferred (the “Series E Redemption”) for approximately $80 million, which includes $78.3 million for the liquidation preference of $1,000 per share, plus accumulated dividends (the “Liquidation Preference”) as shown in the table below and $1.7 million for the participation rights value associated with the Series E Redemption. The Series E Redemption was funded from a portion of the proceeds from the sale of our Climate Control Business. After the redemption, 139,768 shares of the Series E Redeemable Preferred remain outstanding.

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

The Series E Redeemable Preferred has a 14% annual dividend rate and a participating right in dividends and liquidating distributions equal to 303,646 as of December 31, 2016. Generally, the holders of the Series E Redeemable Preferred Shares (the “Series E Holders”) will not have any voting rights or powers, and consent of the Series E Holders will not be required for taking of any action by us. However, the Series E Holders’ consent is required for

•

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

•

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

•

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

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

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

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

13. Securities Financing Including Redeemable Preferred Stocks (continued)

common stock having an aggregate common stock price equal to the amount of the aggregate Liquidation Preference of such shares being redeemed in shares of common stock in lieu of cash at the redemption date.

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

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

Series F Redeemable Preferred

The Series F COD authorizes one (1) shares of Series F Redeemable Preferred. The Series F Redeemable Preferred has voting rights (the “Series F Voting Rights”) to vote as a single class on all matters which the common stock have the right to vote and was entitled to a number of votes equal to 4,559,971 shares of our common stock, but, the number of votes that may be cast by the Series F Redeemable Preferred was reduced automatically to 456,225 shares of common stock upon the exercise of the warrants discussed below.

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

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

Warrants

In conjunction with the issuance of the Series E and Series F Redeemable Preferred in December 2015 to the Purchaser, we issued warrants to the Purchaser to purchase 4,103,746 shares of common stock. Each warrant afforded the holder the opportunity to purchase one share of common stock at a warrant exercise price of $0.10. In May 2016, all of the Warrants were exercised by the holder in a cashless exercise resulting in the issuance of 4,103,746 shares of our common stock, of which 34,422 shares of common stock were surrendered (shares classified as treasury stock) by the holder in payment of the exercise price.

Registration Rights Agreement- Warrants

On December 4, 2015 (the date of closing), LSB entered into a registration rights agreement (the “Registration Rights Agreement-Warrants”) relating to the registered resale of the common stock issuable upon exercise of the Warrants and certain other common stock. Pursuant to the Registration Rights Agreement-Warrants, we are required to file a registration statement for such registered resale within nine months from the date of closing, to permit the public resale of registrable securities then outstanding from time to time as permitted by Rule 415 under the Securities Act. During 2016, we filed the registration statement, which was declared effective by the SEC on October 27, 2016.

Amendment to Renewed Rights Agreement

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

Approval of 2016 Long Term Incentive Plan - During 2016, our board of directors adopted our 2016 Long Term Incentive Plan (the “2016 Plan”), which plan was approved by our shareholders at our annual meeting of shareholders held on June 2, 2016. The effective date of the 2016 Plan is April 19, 2016 and no awards may be granted under the 2016 Plan on and after the tenth anniversary of its effective date.

In addition, no further awards will be granted under our 2008 Incentive Stock Plan (the “2008 Plan”) or our Outside Directors Stock Purchase Plan (the “Outside Director Plan”) on or after the effective date of the 2016 Plan. Any awards that remain outstanding under the 2008 Plan or the Outside Director Plan will continue to be governed by the respective plan’s terms and the terms of the specific award agreement, as applicable.

The maximum aggregate number of shares reserved and available for issuance under the 2016 Plan shall not exceed 2,750,000 shares plus any shares that become available for reissuance under the share counting provisions of the 2008 Plan following the effective date of the 2016 Plan, subject to adjustment as permitted under the 2016 Plan. Shares subject to any award that is canceled, forfeited, expires unexercised, settled in cash in lieu of common stock or otherwise terminated without a delivery of shares to a participant will again be available for awards under the 2016 Plan to the extent allowable by law. Under the 2016 Plan, awards may be made to employees, directors and consultants (for services rendered) of LSB or our subsidiaries subject to limitations as defined by the 2016 Plan.

The 2016 Plan will be administered by the compensation committee (the “Committee”) of our board of directors. Our board of directors or the Committee may amend the 2016 Plan, except that if any applicable statute, rule or regulation requires shareholder approval with respect to any amendment of the 2016 Plan, then to the extent so required, shareholder approval will be obtained. Shareholder approval will also be obtained for any amendment that would increase the number of shares stated as available for issuance under the 2016 Plan.

The following may be granted by the Committee under the 2016 Plan:

Stock Options - The Committee may grant either incentive stock options or non-qualified stock options. The Committee sets option exercise prices and terms, except that the exercise price of a stock option may be no less than 100% of the fair market value, as defined in the 2016 Plan, of the shares on the date of grant. At the time of grant, the Committee will have sole discretion in determining when stock options are exercisable and when they expire, except that the term of a stock option cannot exceed 10 years subject to certain conditions.

14. Stockholders’ Equity (continued)

Stock Appreciation Rights (“SARs”) - The Committee may grant SARs as a right in tandem with the number of shares underlying stock options granted under the 2008 Plan or on a stand-alone basis. SARs are the right to receive payment per share of the SAR exercised in stock or in cash equal to the excess of the share’s fair market value, as defined in the 2008 Plan, on the date of exercise over its fair market value on the date the SAR was granted. Exercise of a SAR issued in tandem with stock options will result in the reduction of the number of shares underlying the related stock option to the extent of the SAR exercise.

Stock Awards, Restricted Stock, Restricted Stock Units, and Other Awards - The Committee may grant awards of restricted stock, restricted stock units, and other stock and cash-based awards, which may include the payment of stock in lieu of cash (including cash payable under other incentive or bonus programs) or the payment of cash (which may or may not be based on the price of our common stock).

Stock Incentive Plans - The following information relates to our long-term incentive plans:

	December 31, 2016
	2016 Plan		2008 Plan
Maximum number of securities for issuance		2,750,000
Number of awards available to be granted (1)		2,632,332

Number of options outstanding		—		219,230
Number of options exercisable		—		131,705

(1)

Includes 2008 Plan shares canceled, forfeited, expired unexercised, which became available for reissuance under the 2016 Plan after the effective date of the 2016 Plan.

Amounts disclosed within this note include amounts attributable to our discontinued operations for prior periods, unless otherwise noted.

Restricted Stock and Restricted Stock Units – During 2016, the Committee approved various grants under the 2016 Plan of shares of restricted stock (“2016 Restricted Stock”) to certain executives and employees. Most of the 2016 Restricted Stock vest at the end of each one-year period at the rate of one-third per year for three years while a portion of these grants vest 100% at the end of three years. On December 31, 2015, the Committee approved the grants under the 2008 Plan of shares of restricted stock (“2015 Restricted Stock”) to certain executives, of which a portion of these awards immediately vested as of the grant date. The non-vested 2016 and 2015 Restricted Stock carry dividend and voting rights. Sales of these shares are restricted prior to the date of vesting. Excluding the shares that immediately vested, the 2015 Restricted Stock vest at the end of each one-year period at the rate of one-third per year for three years. Pursuant to the terms of the 2016 and 2015 Restricted Stock agreements, unvested restricted shares will immediately vest upon the occurrence of a change in control (as defined by agreement), termination without cause or death.

During 2016, four employees surrendered a total of 280,000 shares of stock options previously granted under the 2008 Plan. These employees were also granted shares of restricted stock. These transactions were accounted for as modifications of stock awards. The total incremental fair value of these modified awards (additional compensation cost) was approximately $1.5 million and will be recognized on a straight-line basis over the requisite service period of three years, but the recognition of these costs could be accelerated if the unvested restricted shares immediately vest.

During 2016, the Committee approved the grant of 27,654 shares of Restricted Stock Units (RSU) to our non-employee directors for payment of a portion of their director fees under the 2016 Plan. Each RSU represents a right to receive one share of our common stock following the grant date and are non-forfeitable. Vesting occurs upon the earliest to occur: (i) the director’s separation from service, (ii) the third anniversary of the grant date, or (iii) the occurrence of a change of control as defined by the agreement. Based on terms of the RSU agreements, the grant date fair value of approximately $375,000 or $ 13.56 per share was recognized as stock-based compensation expense (SG&A) on the grant date.

Stock Options - No stock options have been granted under the 2016 Plan. As it relates to stock options granted under the 2008 plan, the exercise price of the outstanding options granted were equal to the market value of our common stock at the date of grant. During 2015, the Committee approved the grants under the 2008 Plan of 135,000 shares of stock options (the “2015 Options”) to certain employees, which grants included 5,000 shares of stock options related to discontinued operations. During 2014, the Committee approved the grants under the 2008 Plan of 489,000 shares of stock options (the “2014 Options”) to certain employees, which grants included 119,000 shares of stock options related to discontinued operations. The exercise price of the 2015 and 2014 Options was equal to the market value of our common stock at the date of grant. The 2015 and 2014 Options vest at the end of each one-year period at the rate of 16.5% per year for the first five years and the remaining unvested options will vest at the end of the sixth year. The 2015 and 2014 Options expire in 2025 and 2024, respectively. The fair value for the 2015 and 2014 Options was estimated, using an option pricing model, as of the date of the grant, which date was also the service inception date.

14. Stockholders’ Equity (continued)

The fair value for the 2015 and 2014 Options was estimated using a Black-Scholes-Merton option pricing model with the following assumptions:

•

risk-free interest rate based on an U.S. Treasury zero-coupon issue with a term approximating the estimated expected life as of the grant date;

•

a dividend yield based on historical data;

•

volatility factors of the expected market price of our common stock based on historical volatility of our common stock primarily over approximately six years from the date of grant; and

•

a weighted-average expected life of the options based on the historical exercise behavior of these employees and outside director, if applicable.

Preferred Share Rights Plan - On January 5, 2009, a renewed shareholder rights plan (the “Renewed Rights Agreement”) became effective upon the expiration of our previous shareholder rights plan. Pursuant to the Securities Purchase Agreement as discussed in Note 13 – Securities Financing, on December 4, 2015, LSB and UMB, as rights agent, entered into an amendment to the Renewed Rights Agreement (the “Renewed Rights Amendment”). The Renewed Rights Amendment amends the definition of “Acquiring Person” to exclude the Purchaser and its Affiliates and Associates (as defined therein) in order to permit the issuance of the Securities discussed in Note 13, and additional securities issuable to the Purchaser as contemplated by the terms of the Securities, without triggering the issuance of Series 4 Junior Participating Class C Preferred Stock. The Renewed Rights Agreement will affect a potential acquirer unless the acquirer negotiates with our Board and the Board approves the transaction. Pursuant to the renewed plan, one preferred share purchase right (a “Right”) is attached to each currently outstanding or subsequently issued share of our common stock. Prior to becoming exercisable, the Rights trade together with our common stock. In general, if a person or group acquires or announces a tender or exchange offer for 15% or more of our common stock (except for the Golsen Holders and certain other limited excluded persons, as amended), then the Rights become exercisable. Each Right entitles the holder (other than the person or group that triggers the Rights being exercisable) to purchase from us one one-hundredth of a share of Series 4 Junior Participating Preferred Stock, no par value (the “Preferred Stock”), at an exercise price of $47.75 per one one-hundredth of a share, subject to adjustment. If a person or group acquires 15% or more of our common stock, each Right will entitle the holder (other than the person or group that triggered the Rights being exercisable) to purchase shares of our common stock (or, in certain circumstances, cash or other securities) having a market value of twice the exercise price of a Right at such time. Under certain circumstances, each Right will entitle the holder (other than the person or group that triggered the Rights being exercisable) to purchase the common stock of the acquirer having a market value of twice the exercise price of a Right at such time. In addition, under certain circumstances, our Board may exchange each Right (other than those held by the acquirer) for one share of our common stock, subject to adjustment. Our Board may redeem the Rights at a price of $0.01 per Right generally at any time before 10 days after the Rights become exercisable. Our Board may exchange all or part of the Rights (except to the person or group that triggered the Rights being exercisable) for our common stock at an exchange ratio of one common share per Right until the person triggering the Right becomes the beneficial owner of 50% or more of our common stock.

Other – As of December 31, 2016, we have reserved 1.5 million shares of common stock issuable upon potential conversion of preferred stocks and equity awards pursuant to their respective terms.

Executive Benefit Agreements, Employee Savings Plans and Collective Bargaining Agreements

16. Executive Benefit Agreements, Employee Savings Plans and Collective Bargaining Agreements

We are party to an individual benefit agreement (“1992 Agreement”) with a former executive, death benefit agreements (“1981 Agreements”) with a former executive and with our Executive Chairman, and a death benefit agreement (“2005 Agreement”) with our Executive Chairman. The 1992 Agreement provides for annual benefit payments for life payable in monthly installments.

The 1981 Agreements provide for death benefits should the executive die while employed. Upon such of an event, we will pay the beneficiary named in the agreement a monthly amount as specified in the agreement over a ten-year period. These benefits are forfeited if the respective executive’s employment is terminated for any reason prior to death. The 1981 Agreements may be terminated by the Company at any time and for any reason prior to the death of the employee.

The 2005 Agreement provides that, upon our Executive Chairman’s death, we will pay to our Executive Chairman’s designated beneficiary, a lump-sum payment of $2,500,000 to be funded from the net proceeds received by us under certain life insurance policies on our Executive Chairman’s life that are owned by us. We are obligated to keep in existence life insurance policies with a total face amount of no less than $2,500,000 of the stated death benefit. The benefit under the 2005 Agreement is not contingent upon continued employment and may be amended at any time by written agreement executed by the Executive Chairman and the Company.

During 2016 and 2015, the employment of certain executives, subject to the provisions of the 1981 and 1992 Agreements, were terminated, resulting in the forfeiture of the respective benefits. As a result of these events, the accrual for these estimated benefits was derecognized resulting in a net recovery of costs associated with certain executive benefits.

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

To assist us in funding the benefit agreements discussed above and for other business reasons, we purchased life insurance policies on various individuals in which we are the beneficiary. Some of these life insurance policies have cash surrender values that we have borrowed against. The net cash surrender values of these policies are included in other assets.

We do not presently contribute to this plan except for certain employees, which amounts were not material for each of the three years ended December 31, 2016.

Collective Bargaining Agreements - As of December 31, 2016, we employed 610 persons, 195 of whom are represented by unions under agreements, which will expire in July of 2018 through November of 2019.

Related Party Transactions	18. Related Party Transactions During 2016, we entered into a consulting agreement with Steven J. Golsen (“S. Golsen”), son of Jack E. Golsen and former employee and President and Chief Operating Officer of the Climate Control Business. Pursuant to the terms of the agreement, S. Golsen is to provide services relating to the sale of the Climate Control Business and subsequent services to improve the transition process from LSB to NIBE. The total consulting fee is $425,000 and the term of the agreement is for 2 years, but could be terminated earlier under certain circumstances. During 2016, we executed agreements, sold and assigned our rights in certain life insurance policies owned by us as beneficiary. The purchase price of these policies was the cash surrender value at the time of purchase. These policies insured our two Board members, Jack E. Golsen and Barry H. Golsen and a former employee, S. Golsen. We received approximately $1.7 million from the sale of these life insurance policies. During 2016, we incurred consulting fees of approximately $135,000 from one of our Board members, Mr. Richard Sanders. These fees relate to services performed by Mr. Sanders as an Interim Executive Vice President, Chemical Manufacturing, which involved the oversight of our chemical plant operations during this time period. On August 1, 2016, these consulting services ceased when we appointed Mr. John Diesch in this executive position. In 2015 and 2014 (none in 2016), we paid annual dividends totaling $300,000 on our Series B Preferred and our Series D Preferred. At December 31, 2016, the amount of accumulated dividends on the Series B and Series D Preferred totaled approximately $378,000. The Series B Preferred and Series D Preferred are non-redeemable preferred stocks issued in 1986 and 2001, respectively, of which all outstanding shares are owned by the Golsen Holders.

Extraordinary And Unusual Items [Abstract]
Property and Business Interruption Insurance Claims and Recoveries	20. Property and Business Interruption Insurance Claims and Recoveries On November 13, 2012, a pipe ruptured within our Cherokee Facility causing damage primarily to the heat exchanger portion of its ammonia plant. No serious injuries or environmental effect resulted from the pipe rupture. As a result of the damage, the Cherokee Facility could only produce, on a limited basis, nitric acid and AN solution from purchased ammonia until the repairs were completed. Our insurance policy provided, for the policy period covering this claim, for repair or replacement cost coverage relating to property damage with a $2.5 million deductible and provided for business interruption coverage for certain lost profits and extra expense with a 30-day waiting period. As a result of this event, a notice of insurance claims for property damage and business interruption was filed with the insurance carriers. In 2013, we received business interruption insurance recovery of $15 million and was applied against recoverable costs (primarily relating to additional expenses associated with purchased product sold or used in products sold to our customers while our facility was being repaired) totaling $13.6 million as a reduction to cost of sales. The insurance recovery in excess of recoverable costs of $1.4 million was deferred (included in deferred gain on insurance recoveries at December 31, 2013) since this amount relates to lost profits, which is considered a gain contingency. In January 2014, we settled the claim with our insurance carriers for the aggregate amount of approximately $43.5 million (of which approximately $36.5 million relates to the business interruption claim), comprised of $15 million previously paid to us in 2013 and $28.5 million paid to us in 2014. The $43.5 million settlement amount is net of our $2.5 million property insurance deductible. As a result, an insurance recovery of approximately $28 million was recognized as a reduction to cost of sales associated with this settlement in 2014.

21. Subsequent Events

Working Capital Revolver Loan - On January 17, 2017, we and each of our subsidiaries signatory thereto entered into the Third Amended and Restated Loan and Security Agreement (the “Working Capital Revolver Loan Amendment”), with certain identified lenders and Wells Fargo Capital Finance, LLC (“Wells Fargo”), as the arranger and administrative agent. The Working Capital Revolver Loan Amendment amends and restates our existing senior secured revolving credit facility (as so amended and restated, the “Working Capital Revolver Loan”).

We and all of our existing subsidiaries, other than Zena, are co-borrowers (“Borrowers”) under the Working Capital Revolver Loan. The revolver commitment is for $50 million (formerly $100 million), but provides an ability to expand the commitment an additional $25 million. Interest accrues on outstanding borrowings under the Working Capital Revolver Loan at a rate equal to, at our election, either (a) LIBOR for an interest period selected by us plus an applicable margin equal to 1.50% per annum or 1.75% per annum, depending on borrowing availability under the Working Capital Revolver Loan or (b) Wells Fargo’s prime rate plus an applicable margin equal to 0.50% per annum or 0.75% per annum, depending on borrowing availability under the Working Capital Revolver Loan. In addition, unused line fees in an amount equal to 0.25% per annum on the average daily balance of the unused revolver commitments under the Working Capital Revolver Loan are payable by us, as well as customary fees in respect of letters of credit. At January 31, 2017, the interest rate was 4.25% based on LIBOR. Interest is paid monthly, if applicable.

Advances under the Working Capital Revolver Loan are based on specified percentages of eligible accounts receivable and inventories. The Working Capital Revolver Loan provides for a subfacility for the issuances of up to letters of credit in an aggregate amount not to exceed to $10 million, with the outstanding amount of any such letters of credit reducing availability for borrowings under the Working Capital Revolver Loan. At January 31, 2017, the amount available for borrowing under the Working Capital Revolver was $40.5 million.

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 does not include any amortization, and all borrowings under the Working Capital Revolver Loan are due on the relevant maturity date.

The Working Capital Revolver Loan Amendment 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 monthly.

21. Subsequent Events (continued)

The Working Capital Revolver Loan Amendment permits the Borrowers to make any investment as long as the borrowing availability is 20% of the revolver commitment, or $10 million.

The Working Capital Revolver Loan Amendment contains covenants that, among other things, limit the Borrowers’ ability, without consent of the lender and with certain exceptions, to:

•

incur additional indebtedness;

•

create liens on, sell or otherwise dispose of our assets;

•

engage in certain fundamental corporate changes or changes to our business activities;

•

make certain material acquisitions;

•

make other restricted payments;

•

repay certain indebtedness;

•

engage in certain affiliate transactions;

•

declare dividends and distributions;

•

engage in mergers, consolidations or other forms of recapitalization; or

•

dispose assets.

The Working Capital Revolver Loan Amendment allows each of the Borrowers to perform certain transactions when specified criteria are met. The criteria includes that there is no default under the Working Capital Revolver Loan and both immediately before and after giving effect to any of the following transactions, availability, as defined by the Working Capital Revolver Loan Amendment, is equal to or greater than the greater of 20% of the maximum revolver commitment or (y) $10 million,

•

distributions, dividends, purchase, acquire, redeem or retire its stock with respect to amounts in excess of $0.5 million during each fiscal year;

•

certain hedging agreements and;

•

certain investments, including, among others, investments in joint ventures in an aggregate amount not exceeding $35.0 million; and

•

certain additional indebtedness.

The Working Capital Revolver Loan Amendment includes customary events of default, including events of default relating to nonpayment of principal and other amounts owing under the Working Capital Revolver Loan from time to time, any material misstatement or misrepresentation and breaches of representations and warranties made, violations of covenants, cross-payment default to indebtedness in excess of $10 million, cross-acceleration to indebtedness in excess of $10 million, bankruptcy and insolvency events, certain unsatisfied judgments, certain liens, and certain assertions of, or actual invalidity of, certain loan documents. Upon the occurrence of events of default, the obligations under the Working Capital Revolver Loan may be accelerated and the revolver commitments may be terminated.

Obligations under the Working Capital Revolver Loan are secured by a first priority security interest in substantially all of the borrowers’ current assets, including accounts receivable and inventory, with exceptions set forth in the Amendment and related loan documents. The Working Capital Revolver Loan allows the Borrowers and subsidiaries under the Senior Secured Notes to guarantee those notes.

Summary of Significant Accounting Policies (Policies)	12 Months Ended
Summary of Significant Accounting Policies (Policies)	Dec. 31, 2016
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 consolidated financial statements. LSB is a holding company with no significant operations or assets other than cash, cash equivalents, and investments in its subsidiaries. Our ownership of working interests in natural gas properties is accounted for as an undivided interest, whereby we reflect our proportionate share of the underlying assets, liabilities, revenues and expenses. Our working interest represents our share of the costs and expenses incurred primarily to develop the underlying leaseholds and to produce natural gas while our net revenue interest represents our share of the revenues from the sale of natural gas. The net revenue interest is less than our working interest as the result of royalty interest due to others. We are not the operator of these natural gas properties. Entities that were 20% to 50% owned and for which we had significant influence were accounted for on the equity method. All material intercompany accounts and transactions have been eliminated.
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 AN (“HDAN”), UAN, and AN ammonia solution for agricultural applications, high purity and commercial grade ammonia, high purity AN, sulfuric acids, concentrated, blended and regular nitric acid, mixed nitrating acids, carbon dioxide, and diesel exhaust fluid for industrial applications, and industrial grade AN (“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; industrial users of acids throughout the United States (U.S.) and parts of Canada; and explosive manufacturers in the U.S. Our other products consist of natural gas sales from our working interests in certain natural gas properties and sales of industrial machinery and related components. For 2016, 2015 and 2014, these sales totaled $9.1 million, $12.9 million and $24.5 million, respectively. On May 11, 2016, LSB, Consolidated Industries L.L.C., a direct, wholly owned subsidiary of LSB (“Consolidated”), and Climate Control Group, Inc., a direct, wholly owned subsidiary of Consolidated and an indirect subsidiary of LSB (the “Climate Control Group”), entered into a Stock Purchase Agreement (the “Stock Purchase Agreement”) with NIBE Industrier AB (publ), and NIBE Energy Systems Inc., an indirect wholly owned subsidiary of NIBE Industrier AB (collectively “NIBE”) pursuant to which LSB, through Consolidated, agreed to sell to NIBE all of the outstanding shares of stock of the Climate Control Group for a total of approximately $364 million, subject to post-closing adjustments, which sale was completed on July 1, 2016. The Climate Control Group conducted LSB’s Climate Control Business (the “Climate Control Business”). The assets and liabilities of Climate Control Business have been reclassified and reported as held for sale as of December 31, 2015. Furthermore, the operating activities of Climate Control Business have been reclassified and reported as discontinued operations for all periods presented. Our financial statements and footnotes reflect our results from continuing operations unless otherwise noted. Our financial statements and footnotes reflect our results from continuing operations unless otherwise noted. See Note 2 – Discontinued Operations.
Use of Estimates	Use of Estimates - The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Cash and Cash Equivalents	Cash and Cash Equivalents – Investments, which consist of highly liquid investments with original maturities of three months or less, are considered cash equivalents.
Accounts Receivable	Accounts Receivable - Our accounts receivable are stated at net realizable value. This value includes an appropriate allowance for estimated uncollectible accounts to reflect any loss anticipated on accounts receivable balances. Our estimate is based on historical experience and periodic assessment of outstanding accounts receivable, particularly those accounts that are past due (based upon the terms of the sale). Our periodic assessment of our accounts receivable is based on our best estimate of amounts that are not recoverable.
Inventories	Inventories - Inventories are stated at the lower of cost (determined using the first-in, first-out (“FIFO”) basis) or market (net realizable value). Finished goods include material, labor, and manufacturing overhead costs.
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.
Property, Plant and Equipment	Property, Plant and Equipment - Property, plant and equipment (“PP&E”) are stated at cost, net of accumulated depreciation, depletion and amortization (“DD&A”). Leases meeting capital lease criteria are capitalized in PP&E. Major renewals and improvements that increase the life, value, or productive capacity of assets are capitalized in PP&E while maintenance, repairs and minor renewals are expensed as incurred. In addition, maintenance, repairs and minor renewal costs relating to planned major maintenance activities (“Turnarounds”) are expensed as they are incurred. All long-lived assets relate to domestic operations. As it relates to natural gas properties, leasehold costs, intangible drilling and other costs of successful wells and development dry holes are capitalized in PP&E based on successful efforts accounting. The costs of exploratory wells are initially capitalized in PP&E, but expensed if and when the well is determined to be nonproductive. Fully depreciated assets are retained in PP&E and accumulated DD&A accounts until disposal. When PP&E are retired, sold, or otherwise disposed, the asset’s carrying amount and related accumulated DD&A are removed from the accounts and any gain or loss is included in other income or expense. For financial reporting purposes, depreciation of the costs of PP&E is primarily computed using the straight-line method over the estimated useful lives of the assets. No provision for depreciation is made on construction in progress or capital spare parts until such time as the relevant assets are put into service. DD&A of the costs of producing natural gas properties are computed using the units of production method primarily on a field-by-field basis using total proved or proved developed reserves, as applicable, as estimated by our independent consulting petroleum engineer. No provision for DD&A is made on nonproducing leasehold costs and exploratory wells in progress until such time as the relevant assets relate to proven reserves. Our natural gas reserves are based on estimates and assumptions, which affect our DD&A calculations. Our independent consulting petroleum engineer, with our assistance, prepares estimates of natural gas reserves based on available relevant data and information. For DD&A purposes, and as required by the guidelines and definitions established by the Securities and Exchange Commission (“SEC”), the reserve estimates are based on average natural gas prices during the 12-month period, determined as an unweighted arithmetic average of the first-day-of-the-month price for each month.
Impairment of Long-Lived Assets and Goodwill	Impairment of Long-Lived Assets and Goodwill - Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset (asset group) may not be recoverable. An impairment loss would be recognized when the carrying amount of an asset (asset group) exceeds the estimated undiscounted future cash flows expected to result from the use of the asset (asset group) and its eventual disposition. If assets to be held and used are considered to be impaired, the impairment to be recognized is the amount by which the carrying amounts of the assets exceed the fair values of the assets as measured by the present value of future net cash flows expected to be generated by the assets or their appraised value. In general, and depending on the event or change in circumstances, our asset groups are reviewed for impairment on a facility-by-facility basis (such as the Cherokee, El Dorado or Pryor Facility). As it relates to natural gas properties, proven natural gas properties are reviewed for impairment on a field-by-field basis and nonproducing leasehold costs are reviewed for impairment on a property-by-property basis. In addition, if the event or change in circumstance relates to the possible sale of an asset (or group of assets), the specific asset (or group of assets) is reviewed for impairment. In addition, goodwill is reviewed for impairment at least annually. An impairment loss generally would be recognized when the carrying amount of the reporting unit’s net assets exceeds the estimated fair value of the reporting unit. At December 31, 2015, other assets included goodwill of $1.6 million related to the acquisition of our El Dorado Facility. See discussion below under 2016. In general, assets held for sale are reported at the lower of the carrying amounts of the assets or fair values less costs to sell. At December 31, 2015, long-lived assets classified as assets held for sale related to the Climate Control Business as discussed above and in Note 2 – Discontinued Operations (none at December 31, 2016). 1. Summary of Significant Accounting Policies (continued) The non-cash impairment charges discussed below were included in the consolidated statements of operations line item titled impairment of long-lived assets and goodwill. 2016 Generally, the evaluation of goodwill for impairment involves a two-step test. Step 1 involves comparing the estimated fair value of each respective reporting unit to its carrying value, including goodwill. Our step 1 test utilized both a market approach and income approach to estimate the fair values of our reporting units. The market approach was based on enterprise value to estimated EBITDA multiples of our peer group (Level 3 inputs). If the estimated fair value exceeds the carrying value, the reporting unit’s goodwill is not considered impaired. If the carrying value exceeds the estimated fair value, step 2 must be performed to determine whether goodwill is impaired and, if so, the amount of the impairment. Step 2 involves calculating an implied fair value of goodwill by performing a hypothetical allocation of the estimated fair value of the reporting unit determined in step 1 to the respective tangible and intangible net assets of the reporting unit (Level 3 inputs). The remaining implied goodwill is then compared to the actual carrying amount of the goodwill for the reporting unit. To the extent the carrying amount of goodwill exceeds the implied goodwill, the difference is the amount of the goodwill impairment. During 2016, pricing for our key product groups deteriorated well below expectations foreseen at December 31, 2015. Additionally, we believe the lower price environment is expected to continue throughout 2017. Thus, in accordance with ASC 350, we determined it was more likely than not that the fair value of goodwill related to our El Dorado Facility was less than its carrying amount (goodwill and other) implied under step 2 resulting in an impairment charge of $1.6 million to fully write-down the carrying value of goodwill. 2015 During 2015, we recognized an impairment charge of $39.7 million to write-down the carrying value ($62.2 million) of our working interest in natural gas properties in the Marcellus Shale region to their estimated fair value of $ 22.5 million. The impairment charge represented the amount by which the carrying value of these natural gas properties exceeded the estimated fair value and was therefore not recoverable. The estimated fair value was determined based on estimated future discounted net cash flows, a Level 3 input, using estimated production and prices at which we reasonably expect natural gas will be sold, including the evaluation provided by our independent consulting petroleum engineer in October 2015. The event triggering the review for impairment related primarily from the results received from the evaluation. The impairment was due to the decline in prices for natural gas futures, large natural gas price differentials in the Marcellus Shale region and the resulting changes in the drilling plans of these natural gas properties that caused certain of these properties to be reclassified from the “proved undeveloped reserves” category to the “probable undeveloped resources” category included in the Evaluation because those properties are no longer likely to be developed within five years. Our independent consulting petroleum engineering firm calculated our natural gas reserves using volumetric analysis of the reservoir and rate decline analysis for existing producers. The process of estimating proved reserves and future net cash flows is complex involving decisions and assumptions in evaluating the available engineering and geologic data and natural gas prices and the cost to produce these reserves and other factors, many of which are beyond our control. These assumptions include estimates of future natural gas production, commodity prices based on commodity futures price strips, operating and development costs, and a risk-adjusted discount rate of 10%, which is based on an industry standard. As a result, these estimates are imprecise and should be expected to change as future information becomes available. These changes could be significant. As a non-operator of our natural gas properties, we rely on information provided from the operator which is given to our independent consulting petroleum engineering firm for use in the preparation of our reserve estimates. The reserve estimates are reviewed by certain members of our accounting group for accuracy and checked for consistency in its preparation along with validating the assumptions provided by the operator based on actual performance. Additionally, members of management met with the operator periodically to review our properties and discuss performance. In addition, during 2015, we recognized an impairment charge of $3.5 million to write down the carrying value ($8.5 million) of certain plant assets related to certain ammonia production equipment at our Pryor Facility to their estimated fair value of approximately $ 5.0 million. The change of circumstances triggering the review for impairment related primarily to an offer received from a possible buyer on this non-core ammonia production equipment. The estimated fair value was determined based on an offer received from a possible buyer less estimated costs that would be incurred if the equipment is sold (Level 3 inputs). In 2016, this ammonia production equipment was sold to a third party for a minimal gain.
Concentration of Credit Risks for Cash and Cash Equivalents and Sales	Concentration of Credit Risks for Cash and Cash Equivalents and Sales – Financial instruments relating to cash and cash equivalents potentially subject us to concentrations of credit risk. All of these financial instruments were held by financial institutions within the U.S. and none of these financial instruments were in excess of the federally insured limits. Net sales to one customer, Koch Fertilizer LLC, represented approximately 11%, 12% and 7% of our total net sales for 2016, 2015 and 2014, respectively. Net sales to one customer, Covestro AG, represented approximately 13%, 15% and 14% of our total net sales for 2016, 2015 and 2014, respectively. The sales to Covestro are pursuant to an agreement under which one of our subsidiaries operates a nitric plant located within Covestro’s chemical manufacturing complex as discussed in Note 11 – Commitments and Contingencies. This agreement: (a) allows us to pass-through most of the costs of producing the nitric acid that Covestro purchases, including the cost of ammonia; (b) to receive management fees for managing the operations and marketing nitric acid at the Baytown Facility and; (c) to receive a portion of any carbon credits that are sold.
Capitalized Software	Capitalized Software – Intangible and other noncurrent assets include capitalized software that primarily relates to our enterprise resource planning software (“ERP”) for internal use and is stated at cost, net of accumulated amortization. The ERP project was completed during 2016. For 2016 and 2015 our carrying value was $12.9 million and $12.8 million, and accumulated amortization of $3.5 million and $1.8 million, respectively. Capitalized software costs include software purchase costs and internal and external costs for implementing software. For financial reporting purposes, amortization of capitalized software costs is computed using the straight-line method over the estimated useful lives of the software, which is primarily eight years. During 2016, 2015, and 2014, interest cost capitalized in capitalized software was $0.1 million, $0.3 million, and $0.5 million, respectively. Interest costs capitalized ceased during 2016 with the completion of the ERP project. No provision for amortization is made until such time as the relevant assets are placed into service. Amortization expense related to capitalized software was $1.7 million, $1.0 million and $0.3 million for 2016, 2015 and 2014, respectively. Estimated amortization related to capitalized software is $1.7 million for 2017, $1.6 million for 2018 and $1.5 million each of the subsequent three years, 2019 through 2021.
Capitalized Interest	Capitalized Interest - Interest cost on borrowings incurred during a significant construction or development project is capitalized. Capitalized interest is added to the associated underlying asset and amortized over the estimated useful lives of the assets. For 2016, 2015 and 2014, interest capitalized amounted to $15.0 million, $30.6 million, $14.1 million, respectively.
Accrued Insurance Liabilities	Accrued Insurance Liabilities - We are self-insured up to certain limits for group health, workers’ compensation and general liability claims. Above these limits, we have commercial stop-loss insurance coverage for our contractual exposure on group health claims and statutory limits under workers’ compensation obligations. We also carry umbrella insurance of $100 million for most general liability and auto liability risks. We have a separate $50 million insurance policy covering pollution liability at our chemical facilities. Additional pollution liability coverage for our other facilities is provided in our general liability and umbrella policies. As it relates to our natural gas properties that we do not operate but only own a working interest, insurance policies are maintained by the operator, which we are responsible for our proportionate share of the costs involved. Our accrued self-insurance liabilities are based on estimates of claims, which include the reported incurred claims amounts plus the reserves established by our insurance adjustors and/or estimates provided by attorneys handling the claims, if any, up to the amount of our self-insurance limits. In addition, our accrued insurance liabilities include estimates of incurred, but not reported, claims based on historical claims experience. The determination of such claims and the appropriateness of the related liability is periodically reviewed and revised, if needed. Changes in these estimated liabilities are charged to operations. Potential legal fees and other directly related costs associated with insurance claims are not accrued but rather are expensed as incurred. Accrued insurance claims are included in accrued and other liabilities. It is reasonably possible that the actual development of claims could be different than our estimates.
Executive Benefit Agreements	Executive Benefit Agreements - We are party to certain benefit agreements with certain key current and former executives. Costs associated with these individual benefit agreements are accrued based on the estimated remaining service period when such benefits become probable they will be paid. Total costs accrued equal the present value of specified payments to be made after benefits become payable.
Income Taxes	Income Taxes – We recognize deferred tax assets and liabilities for the expected future tax consequences attributable to net operating loss (“NOL”) carryforwards, tax credit carryforwards, and differences between the financial statement carrying amounts and the tax basis of our assets and liabilities. We establish valuation allowances if we believe it is more-likely-than-not that some or all of deferred tax assets will not be realized. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. 1. Summary of Significant Accounting Policies (continued) In addition, we do not recognize a tax benefit unless we conclude that it is more-likely-than-not that the benefit will be sustained on audit by the taxing authority based solely on the technical merits of the associated tax position. If the recognition threshold is met, we recognize a tax benefit measured at the largest amount of the tax benefit that, in our judgment, is greater than 50% likely to be realized. We record interest related to unrecognized tax positions in interest expense and penalties in operating other expense. We reduce income tax expense for investment tax credits in the year the credit arises and is earned. Income tax benefits associated with amounts that are deductible for income tax purposes but that do not affect earnings are credited to equity. These benefits are principally generated from exercises of non-qualified stock options and restricted stock. We adopted ASU No. 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes as discussed below in “Recently Issued Accounting Pronouncements”.
Contingencies	Contingencies – Certain conditions may exist which may result in a loss, but which will only be resolved when future events occur. We and our legal counsel assess such contingent liabilities, and such assessment inherently involves an exercise of judgment. If the assessment of a contingency indicates that it is probable that a loss has been incurred, we would accrue for such contingent losses when such losses can be reasonably estimated. If the assessment indicates that a potentially material loss contingency is not probable but reasonably possible, or is probable but cannot be estimated, the nature of the contingent liability, together with an estimate of the range of possible loss if determinable and material, would be disclosed. Estimates of potential legal fees and other directly related costs associated with contingencies are not accrued but rather are expensed as incurred. Loss contingency liabilities are included in current and noncurrent accrued and other liabilities and are based on current estimates that may be revised in the near term. In addition, we recognize contingent gains when such gains are realized or realizable and earned.
Asset Retirement Obligations	Asset Retirement Obligations - In general, we record the estimated fair value of an asset retirement obligation (“ARO”) associated with tangible long-lived assets in the period it is incurred and when there is sufficient information available to estimate the fair value. An ARO associated with long-lived assets is a legal obligation under existing or enacted law, statute, written or oral contract or legal construction. AROs, which are initially recorded based on estimated discounted cash flows, are accreted to full value over time through charges to cost of sales. In addition, we capitalize the corresponding asset retirement cost as PP&E, which cost is depreciated or depleted over the related asset’s respective useful life. We do not have any assets restricted for the purpose of settling our AROs.
Redeemable Preferred Stocks	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. See discussion concerning the redemption of a portion of the Series E Redeemable Preferred in Note 11 – Securities Financing including Redeemable Preferred Stocks.
Warrant	Warrants - The common stock warrants issued in conjunction with our redeemable preferred stocks were standalone instruments, indexed to our common stock, and did not include provisions requiring liability classification. As a result, these warrants were classified as equity. The warrants were recorded at fair value upon issuance, net of issuance costs or discounts. See discussion concerning the exercise of the warrants in Note 11 – Securities Financing including Redeemable Preferred Stocks.
Equity Awards	Equity Awards - Equity award transactions with employees are measured based on the estimated fair value of the equity awards issued. For equity awards with only service conditions that have a graded vesting period, we recognize compensation cost on a straight-line basis over the requisite service period for the entire award. In addition, historically we issue new shares of common stock upon the exercise of stock options but treasury shares may be used.
Revenue Recognition and Other Information	Revenue Recognition and Other Information - We recognize revenue for substantially all of our operations at the time title to the goods transfers to the buyer and there remain no significant future performance obligations by us. All net sales and long-lived assets relate to domestic operations for the periods presented. In addition, net sales to non-U.S. customers were minimal.
Recognition of Insurance Recoveries	Recognition of Insurance Recoveries - If an insurance claim relates to a recovery of our losses, we recognize the recovery when it is probable and reasonably estimable. If our insurance claim relates to a contingent gain, we recognize the recovery when it is realized or realizable and earned. Amounts recoverable from our insurance carriers, if any, are included in accounts receivable. An insurance recovery in excess of recoverable costs relating to a business interruption claim, if any, is a reduction to cost of sales. An insurance recovery in excess of recoverable costs relating to a property insurance claim, if any, is included in property insurance recoveries in excess of losses incurred.
Cost of Sales	Cost of Sales - Cost of sales includes materials, labor and overhead costs to manufacture the products sold plus inbound freight, purchasing and receiving costs, inspection costs, internal transfer costs, loading and handling costs, warehousing costs, railcar lease costs and outbound freight. Maintenance, repairs and minor renewal costs relating to Turnarounds are included in cost of sales as they are incurred. Precious metals used as a catalyst and consumed during the manufacturing process are included in cost of sales. Recoveries and gains from precious metals and business interruption insurance claims are reductions to cost of sales. Provisions for (realization of) losses associated with inventory reserves, gains and losses (realized and unrealized) from our commodities and foreign currency futures/forward contracts, and provision for losses, if any, on firm sales commitments are included in cost of sales.
Selling, General and Administrative Expense	Selling, General and Administrative Expense - Selling, general and administrative expense (“SG&A”) includes costs associated with the sales, marketing and administrative functions. Such costs include personnel costs, including benefits, professional fees, office and occupancy costs associated with the sales, marketing and administrative functions.
Derivatives, Hedges, Financial Instruments and Carbon Credits	Derivatives, Hedges, Financial Instruments and Carbon Credits - Derivatives are recognized in the balance sheet and are measured at fair value. Changes in fair value of derivatives are recorded in results of operations unless the normal purchase or sale exceptions apply or hedge accounting is elected. The fair value amounts recognized for our derivative contracts executed with the same counterparty under a master netting arrangement may be offset. We have the choice to offset or not, but that choice must be applied consistently. A master netting arrangement exists if the reporting entity has multiple contracts with a single counterparty that are subject to a contractual agreement that provides for the net settlement of all contracts through a single payment in a single currency in the event of default on or termination of any one contract. Offsetting the fair values recognized for the derivative contracts outstanding with a single counterparty results in the net fair value of the transactions being reported as an asset or a liability in the balance sheet. We have chosen to present the fair values of our derivative contracts under master netting agreements using a gross fair value presentation as there were no derivatives with fair values that were eligible to be offset as of December 31, 2016 and 2015. The assets for climate reserve tonnes (“carbon credits”) are recognized in the balance sheet and are measured at fair value. Changes in fair value of carbon credits are recorded in results of operations. The liabilities for contractual obligations associated with carbon credits are recognized in the balance sheet and are measured at fair value unless we enter into a firm sales commitment to sell the associated carbon credits. When we enter into a firm sales commitment, the sales price, pursuant to the terms of the firm sales commitment, establishes the amount of the liability for the contractual obligation. Changes in fair value of contractual obligations associated with carbon credits are recorded in results of operations.
Income (Loss) per Common Share	Income (Loss) per Common Share - Net income (loss) attributable to common stockholders is computed by adjusting net income (loss) by the amount of dividends and dividend requirements on preferred stocks and the accretion of redeemable preferred stocks, if applicable. Basic loss per common share is computed by dividing net loss attributable to common stockholders by the weighted average number of common shares outstanding, 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. 1. Summary of Significant Accounting Policies (continued) 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.
Segment Information	Segment Information - With the sale of our Climate Control Business during July 2016, we operate in one principal business segment – our chemical business.
Recently Issued Accounting Pronouncements	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 preliminary 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 our working interest in natural gas properties, performing various services, and rental income. A contract review process is being implemented to obtain and review our new or amended contracts for analysis for adopting this ASU. We will begin to focus on developing a preliminary 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. Although we anticipate that upon adoption of this new ASU, the timing of revenue recognition 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. The guidance requires an entity to measure inventory at the lower of cost or net realizable value, which is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation, rather than the lower of cost or market in the previous guidance. This amendment applies to inventory that is measured using first-in, first-out (FIFO). This amendment is effective for public entities for fiscal years beginning after December 15, 2016, including interim periods within those years. A reporting entity should apply the amendments prospectively with earlier application permitted as of the beginning of an interim or annual reporting period. We do not expect a significant effect from adopting this ASU. In November 2015, the FASB issued ASU No. 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes, which simplifies the presentation of deferred income taxes by eliminating the need for entities to separate deferred income tax liabilities and assets into current and noncurrent amounts in a classified statement of financial position. As a result, all deferred taxes are classified as noncurrent as of December 31, 2016. We adopted this ASU on October 1, 2016 and applied the guidance prospectively to all deferred income taxes. Accordingly, prior period balances have not been reclassified. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which creates Topic 842, Leases, and supersedes the lease requirements in Topic 840, Leases. Topic 842 specifies the accounting for leases. The objective of Topic 842 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. Extensive quantitative and qualitative disclosures, including significant judgments made by management, will be required to provide greater insight into the extent of revenue and expense recognized and expected to be recognized from existing contracts. This ASU is effective for us on January 1, 2019 but early adoption is permitted. This ASU must be adopted using a modified retrospective transition, and provides for certain practical expedients. Transition will require application of the new guidance at the beginning of the earliest comparative period presented. Although we currently have a relative small number of leases, we are evaluating the effect of this guidance on our consolidated financial statements and related disclosures and if we plan to early adopt. 1. Summary of Significant Accounting Policies (continued) In March 2016, the FASB issued ASU No. 2016-09, Compensation—Stock Compensation (Topic 718): Improvements to Employee Share Based Payment Accounting, which amends ASC Topic 718, Compensation - Stock Compensation. ASU 2016-09 includes provisions intended to simplify various aspects related to how share based payments are accounted for and presented in the financial statements. The new guidance among other requirements will require all of the tax effects related to share based payments at settlement (or expiration) to be recorded through the income statement. Currently, tax benefits in excess of compensation cost ("windfalls") are recorded in equity, and tax deficiencies ("shortfalls") are recorded in equity to the extent of previous windfalls, and then to the income statement. This change is required to be applied prospectively to all excess tax benefits and tax deficiencies resulting from settlements after the date of adoption of the ASU 2016-09. Under the new guidance, the windfall tax benefit will be recorded when it arises, subject to normal valuation allowance considerations. This change is required to be applied on a modified retrospective basis, with a cumulative effect adjustment to opening retained earnings. 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 the current requirement to present windfall tax benefits as an inflow from financing activities and an outflow from operating activities. Either prospective or retrospective transition of this provision is permitted. ASU 2016-09 is effective for annual reporting periods beginning after December 15, 2016, and interim periods within that reporting period. The Company will prospectively adopt this standard in first quarter of 2017 and expects a cumulative effect of approximately $1.1 million to be recorded as a deferred tax asset with the offset in retained earnings. Going forward, tax benefits in excess of compensation cost previously recorded in equity will be recorded within the income statement and all tax related cash flows resulting from share based payments will be recorded as an operating activity within the statement of cash flows. 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. This ASU makes eight targeted changes to how cash receipts and cash payments are presented and classified in the statement of cash flows. This ASU is effective for us on January 1, 2018 and adoption will be applied on retrospective basis unless it is impracticable to apply, in which case we would be required to apply the ASU prospectively as of the earliest date practicable. We are currently evaluating the effect of our pending adoption of this ASU on our consolidated financial statements and related disclosures. 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. The amendments in this ASU revise the guidance in Topic 230, Statement of Cash Flows, to require cash and cash equivalents to include restricted cash (and 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. Early adoption is allowed. If an entity adopts early in an interim period, an entity must make any adjustments required to comply with the ASU as of the beginning of the annual period that includes the interim period. We are currently evaluating the effect of our pending adoption of this ASU on our consolidated financial statements and related disclosures.
