Business [Abstract]
Description of the Business	1 . BUSINESS AND ACCOUNTING POLICIES Description of the Business IES Holdings, Inc. is a holding company that owns and manages operating subsidiaries in business activities across a variety of end markets. Our operations are currently organized into four principal business segments, based upon the nature of our services : Communications – Nationwide provider of technology infrastructure products and services to large corporations and independent businesses. Residential – Regional provider of electrical installation services for single-family housing and multi-family apartment complexes. Commercial & Industrial – Provider of electrical and mechanical design, construction, and maintenance services to the commercial and industrial markets in various regional markets and nationwide in certain areas of expertise, such as the power infrastruct ure market. Infrastructure Solutions – Provider of electro-mechanical solutions for industrial operations. The words “IES”, the “Company”, “we”, “our”, and “us” refer to IES Holdings, Inc. and, except as otherwise specified herein, to our wholly-owned subsidiaries. Seasonality and Quarterly Fluctuations Results of operations from our Residential construction segment are seasonal, depending on weather trends, with typically higher revenues generated during spring and summer and lower revenues generated during fall and winter, with an impact from precipitation in the warmer months. The Communications, Commercial & Industrial, and Infrastructure Solutions segments of our business are less subject to seasonal trends, as work in these segments generally is performed inside structures protected from the weather, although weather can still impact these businesses, especially in the early stages of projects. Our service and maintenance business is generally not affected by seasonality. Our volume of business ma y be adversely affected by declines in construction projects resulting from adverse regional or national economic conditions. Quarterly results may also be materially affected by the timing of new construction projects. Results for our Infrastructure Solutions segment may be affected by the timing of outages at o ur customers’ facilities. Accordingly, operating results for any fiscal period are not necessarily indicative of results that may be achieved for any subsequent fiscal period. Basis of Financial Statement Preparation The accompanying unaudited condensed consolidated financial statements include the accounts of IES and its wholly-owned subsidiaries, and have been prepared in accordance with the instructions to interim financial reporting as prescribed by the Securities and Exchange Commission (the “SEC”). The results for the interim periods are not necessarily indicative of results for the entire year. These interim financial statements do not include all disclosures required by U.S. generally accepted accounting principles (“GAAP”), and should be read in conjunction with the consolidated financial statements and notes thereto filed with the SEC in our Annual Report on Form 10-K for the fiscal year ended September 30, 2016 . In the op inion of management, the unaudited condensed consolidated financial statements contained in this report include all known accruals and adjustments necessary for a fair presentation of the financial position, results of operations, and cash flows for the pe riods reported herein. Any such adjustments are of a normal recurring nature . Noncontrolling Interest In conjunction with our purchase of STR Mechanical, LLC (“STR”) during the third quarter of fiscal 2016, we acquired a controlling interest of 80 perce nt of the membership interests of STR. The remaining 20 percent interest, which was retained by the third party sellers, is identified in our financials as no ncontrolling interest and is classified outside of permanent equity on our consolidated balance s heet. See Note 13 – Business Combinations for further discussion. Use of Estimates The preparation of financial statements in conformity with GAAP requires the use of estimates and assumptions by management in determining the reported amounts of assets and liabilities, disclosures of contingent liabilities at the date of the financial statements and the reported amounts of revenues and expenses duri ng the reporting period. Actual results could differ from those estimates. Estimates are primarily used in our revenue recognition of construction in progress, fair value assumptions in accounting for business combination s and analyzing goodwill, investmen ts, intangible assets and long-lived asset impairments and adjustments, allowance for doubtful accounts receivable, stock-based compensation, reserves for legal matters, realizability of defer red tax assets, unrecognized tax benefits and self-insured claims liabilities and related reserves. Accounting Standards Not Yet Adopted In May 2014, the Financial Accounting Standards Board (“FASB” ), issued ASU No. 2014-09, Revenue from Contracts with Customers , a comprehensive new revenue recognition standard which will supersede previous existing revenue recognition guidance. The standard creates a five-step model for revenue recogni tion that requires companies to exercise judgment when considering contract terms and relevant facts and circumstances. The standard also requires expanded disclosures surrounding revenue recognition. The effective date will be the first quarter of our fis cal year ended September 30, 2019. The standard allows for either full retrospective or modified retrospective adoption, and we currently plan to use the modified retrospective basis on the adoption date. We are continuing to evaluate the impact of the ado ption of this standard on our consolidated financial statements. In particular, we continue to analyze areas including contract termination provisions and accounting for change orders. However, we expect that we will continue to recognize revenues for mos t of our fixed-price contracts over time, as services are performed. We are also continuing to assess the necessary changes in processes and controls to meet the disclosure requirements of the new standard. In February 2016, the FASB issued ASU No. 2016 -02, Leases ("ASU 2016-02"). Under ASU 2016-02, lessees will need to recognize a right-of-use asset and a lease liability for all of their leases, other than those that meet the definition of a short-term lease. For income statement purposes, leases must be classified as either operating or finance. Operating leases will result in straight-line expense, similar to current operating leases, while finance leases will result in a front-loaded expense pattern, similar to current capital leases. ASU 2016-02 bec omes effective for the fiscal year ended September 30, 2020. We are currently evaluating whether to early adopt the standard and what impact it will have on our consolidated financial statements. In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows, to standardize the classification of restricted cash and cash equivalents transactions on the statement of cash flows. The new standard is effective for interim and annual reporting periods beginning after December 15, 2017, although early ado ption is permitted. The retrospective transition method will be required for this new guidance. We expect we will adopt this guidance by September 30, 2017, and that it will not have a material impact on our consolidated financial statements. In January 2 017, the FASB issued ASU 2017-01, Business Combinations. This standard clarifies the definition of a business to assist entities with evaluation of whether transactions should be accounted for as acquisitions or disposals of assets or businesses. The new standard is effective for interim and annual reporting periods beginning after December 15, 2017, although early adoption is permitted for certain transactions. The prospective transition method will be required for this new guidance. We do not expect this guidance to have a material impact on our consolidated financial statements. Also in January 2017, the FASB issued ASU 2017-04, Intangibles – Goodwill and Other. This update is intended to simplify the subsequent measurement of goodwill by eliminating t he second step in the current two-step goodwill impairment test. This update is effective for public entities for interim and annual reporting periods beginning after December 15, 2019, although early adoption is permitted for interim and annual goodwill i mpairment tests performed on testing dates after January 1, 2017. The prospective transition method will be required for this new guidance. We do not expect this guidance to have a material impact on our consolidated financial statements. Adoption of New Accounting Pronouncements In March 2016, the FASB issued ASU No. 2016-09, Compensation—Stock Compensation (“ASU 2016-09”). ASU 2016-09 eliminates additional paid in capital pools and requires excess tax benefits and tax deficiencies to be recorded in the income statement when the awards vest or are settled. The accounting for an employee’s use of shares to satisfy the employer’s statutory income tax withholding obligation and the accounting for forfeitures is also changing. ASU 2016-09 is effective for fi scal years beginning after December 15, 2017, with early adoption permitted. We elected to early adopt ASU 2016-09 in the quarter ended December 31, 2016, which required us to reflect any adjustments as of October 1, 2016. We elected to account for forf eitures as they occur to determine the amount of compensation cost to be recognized, resulting in a cumulative effect adjustment of $ 58 to reduce retained earnings for the increase to stock compensation expense. We recorded an offsetting cumulative effect adjustment of $ 362 to increase retained earnings to recognize a deferred tax asset related to tax benefits which were not previously recognized, as the tax deduction related to stock compensation expense resulted in an increase to a net operating loss rat her than a reduction to income tax payable. Amendments to the accounting for minimum statutory withholding tax requirements had no impact to retained earnings as of October 1, 2016. In August 2016, the FASB issued ASU 2016-15 , Statement of Cash Flows , to standardize the classification of certain transactions on the statement of cash flows. These transactions include contingent consideration payments made after a business combination. The new standard is effective for interim and annual reporti ng periods beginning after December 15, 2017, although early adoption is permitted, and requires application using a retrospective transition method. We implemented the standard for the quarter ended March 31, 2017. The adoption had no impact on our state ment of cash flows.

Controlling Shareholder [Abstract]
Controlling Shareholder	2 . CONTROLLING SHAREHOLDER At March 31, 2017 , Tontine Capital Partners, L.P. together with its affiliates (collectively, “Tontine”) was the Company’s controlling shareholder, owning approximately 58 % of the Company’s outstanding common stock according to a Schedule 13D/A filed with the SEC by Tontine on October 5, 2016. Accordingly, Tontine has the ability to exercise significant control over our affairs, including the election of directors and most actions requiring the approval of shareholders. While Tontine is subject to restrictions under federal securities laws on sales of its shares as an affiliate, the Company has filed a shelf registration statement to register all of the shares of IES common stock owned by To ntine at the time of registration. As long as the shelf registration statement remains effective, Tontine has the ability to resell any or all of its registered shares from time to time in one or more offerings, as described in the shelf registration state ment and in any prospectus supplement filed in connection with an offering pursuant to the shelf registration statement. Should Tontine sell or otherwise dispose of all or a portion of its position in IES, a change in ownership of IES could occur. A chan ge in ownership, as defined by Internal Revenue Code Section 382, could reduce the availability of the Company’s net operating losses (“NOLs”) for federal and state income tax purposes. On November 8, 2016, the Company implemented a new tax benefit protect ion plan (the “NOL Rights Plan”). T he NOL Rights Plan was designed to deter an acquisition of the Company's stock in excess of a th reshold amount that could trigger a change of control within the meaning of Internal Revenue Code Section 382. There can be no assurance that the NOL Rights Plan will be effective in deterring a change of ownership or protecting the NOLs. Furthermore, a ch ange in control would trigger the change of control provisions in a number of our material agreements, including our credit facility, bonding agreements with our sureties and our severance arrangements. Jeffrey L. Gendell was appointed as a member of the Board of Directors and as non-executive Chairman of the Board in November 2016. He is the managing member and founder of Tontine, and the brother of David B. Gendell, who has served as a member of the Board of Directors since February 2012, as non-executi ve Vice Chairman of the Board since November 2016 and as non-executive Chairman of the Board from January 2015 to November 2016. David B. Gendell is also an employee of Tontine. The Company is party to a sublease agreement with Tontine Associates, LLC, an affiliate of Tontine, for corporate office space in Greenwich, Connecticut. The lease was renewed for a three-year term in April 2016 with an increase in the monthly rent to $ 8 , reflecting the increase paid by Tontine Associates, LLC to its landlord and the Company’s increased use of the corporate office space. The lease has terms at market rates and payments by the Company are at a rate consistent with that paid by Tontine Assoc iates, LLC to its landlord.

Debt [Abstract]
Debt	3 . DEBT At March 31, 2017 and September 30, 2016 , our long-term debt of $ 29,376 and $ 29,257 , respectively, relates to amounts drawn on our revolving credit facility. Our weighted-average interest rate on these borrowings was 2.99 % at March 31, 2017 , and 2.76 % at September 30, 2016 . At March 31, 2017 , we also had $ 6,634 in outstandi ng letters of credit and total availability of $ 40,686 under this facility without violating our financial covenants. On April 14, 2017, we entered into an amendment and restatement of our revolving credit facility w hich increased the size of the facility and modified certain of its terms, including the financial covenants disclosed in Item 7 of our Annual Report on 10-K for the year ended September 30, 2016. See Note 14 – Subsequent Events for further discussion of this amendment and restatement. The Company was in compliance with all covenants at March 31, 2017. At March 31, 2017 , the carrying value of amounts outstanding on our revolving credit facility approximated fair value, as debt incurs interest at a va riable rate. The fair value of the debt is classified as a level 2 measurement.

Stockholders' Equity [Abstract]
Stockholders' Equity	6 . STOCKHOLDERS’ EQUITY Equity Incentive Plan The Company’s 2006 Equity Incentive Plan, which was amended and restated effective February 9, 2016, provides for grants of stock options as well as grants of stock, including restricted stock. Approximately 3.0 million shares of common stock are authorized for issuance under the amended and restated 2006 Equity Incentive Plan, of which approximately 1,051,757 shares were available for issuance at March 31, 2017 . Stock Repurcha se Program Our Board of Directors has authorized a stock repurchase program for the purchase from time to time of up to 1.5 million shares of the Company’s common stock. Share purchases are made for cash in open market transactions at prevailing market prices or in privately negotiated transactions or otherwise. The timing and amount of purchases under the program are determined based upon prevailing market conditions, our liquidity requirements, contractual restrictions and other factors. All or part of the repurchases may be implemented under a Rule 10b5-1 trading plan, which allows repurchases under pre-set terms at times when the Company might otherwise b e prevented from purchasing under insider trading laws or because of self-imposed blackout periods. The program does not require the Company to purchase any specific number of shares and may be modified, suspended or reinstated at any time at the Company’s discretion and without notice. We made no purchases of stock pursuant to this plan during the six months ended March 31, 2017 and 2016 . Treasury Stock During the six months ended March 31, 2017 , we repurchased 683 shares of common stock from our employees to satisfy minimum tax withholding requirements upon the vesting of restricted stock issued under the 2006 Equity Incentive Plan, as amended and restated. During the six months ended March 31, 2017 , we issued 1,287 unrestricted shares of common stock from treasury stock to members of our Board of Directors as part of their overa ll compensation, and 14,750 unrestricted shares of common stock to satisfy the exercise of outstanding options. During the six months ended March 31, 2016 , we repurchased 2,140 shares of common stock from our employees to satisfy minimum tax withholding requirements upon the vesting of restricted stock issued under the 2006 Equity Incentive Plan and 7,500 shares of common stock were forfeited by former employees and returned to tre asury stock. We issued 3,905 unrestricted shares of common stock from treasury stock to members of our Board of Directors as part of their overall compensation, and 15,000 unrestricted shares to satisfy th e exercise of outstanding options. Restricted Stock During the three months ended March 31, 2017 and 2016 , we recognized $ 136 and $ 130 , respectively, in compensation expense related to our restricted stock awards . During the six months ended March 31, 2017 and 2016 , we recognized $ 273 and $ 262 , respectively, in compensation expense related to our restricted stock awards . At March 31, 2017 , t he unamortized compensation cost related to outstanding unvested restricted stock was $ 541 . Performance Cash Units Performance based phantom cash units (“PPCUs”) are a contractual right to cash payment of $ 20 dollars per PPCU. At March 31, 2017 , the Company had outstanding an aggregate of 30,000 PPCUs, which will generally become vested, if at all, upon achievement of certain specified performance objectives and continued performance of services through mid-December 2018 , each of which as of March 31, 2017 are dee med probable. During the three months ended March 31, 2017 , and 2016 , we recognized compensation expense of $ 58 and zero , respectively, related to these units. During the six months ended March 31, 2017 , and 2016 , we recognized compensation expense of $ 193 and zero , respectively, related to these units. Phantom Stock Units Phantom stock units (“PSUs”) are primarily granted to the members of the Board of Directors as part of their overall compensation. These PSUs are paid via unrestricted stock grants to each director upon their departure from the Board of Directors. We record compensation expense for the full value of the grant on the date of grant. For the three months ended March 31, 2017 and 2016 , we recognized $ 40 and $ 34 , respectively, i n compensation expense related to these grants. During the six months ended March 31, 2017 and 2016 , we recognized $ 84 and $ 68 , respectively, in compensation expense related to these grants.

Fair Value Measurements [Abstract]
Fair Value Measurements	9 . FAIR VALUE MEASUREMENTS Fair Value Measurement Accounting Fair value is considered the price to sell an asset, or transfer a liability, between market participants on the measurement date. Fair value measurements assume that the asset or liability is (1) exchanged in an orderly manner, (2) the exchange is in the principal market for that asset or liability, and (3) the market participants are independent, knowledgeable, able and willing to transact an exchange. Fair value accoun ting and reporting establishes a framework for measuring fair value by creating a hierarchy for observable independent market inputs and unobservable market assumptions and expands disclosures about fair value measurements. Considerable judgment is require d to interpret the market data used to develop fair value estimates. As such, the estimates presented herein are not necessarily indicative of the amounts that could be realized in a current exchange. The use of different market assumptions and/or estimati on methods could have a material effect on the estimated fair value. At March 31, 2017 , financial assets and liabilities measured at fair value on a recurring basis were limited to our Executive Deferred Compensation Plan, under which certain employees are permitted to defer a portion of their base salary and/or bonus for a Plan Year (as defined in the plan ), and contin gent consideration liabilities related to our acquisition s of Calumet Armature & Electric, LLC (“Calumet”) in October 2015 and Freeman Enclosure Systems, LLC and its affiliate Strategic Edge LLC (together, “Freeman”) in March 2017. Financial assets and liabilities measured at fair value on a recurring basis as of March 31, 2017 , are summarized in the following table by the type of inputs applicable to the fair value measurements: March 31, 2017 Total Fair Value Quoted Prices (Level 1) Significant Unobservable Inputs (Level 3) Executive savings plan assets $ 630 $ 630 $ - Executive savings plan liabilities (514) (514) - Contingent consideration (1,112) - (1,112) Total $ (996) $ 116 $ (1,112) Financial assets and liabilities measured at fair value on a recurring basis as of September 30, 2016 , are summarized in the following table by the type of inputs applicable to the fair value measurements: September 30, 2016 Total Fair Value Quoted Prices (Level 1) Significant Unobservable Inputs (Level 3) Executive savings plan assets $ 599 $ 599 $ - Executive savings plan liabilities (486) (486) - Contingent consideration (1,100) - (1,100) Total $ (987) $ 113 $ (1,100) In fiscal years 2016 and 2017, we entered into contingent consideration arrangements related to certain acquisitions .

Commitments And Contingencies [Abstract]
Legal Matters	12 . COMMITMENTS AND CONTINGENCIES Legal Matters From time to time we are a party to various claims, lawsuits and other legal proceedings that arise in the ordinary course of business. We maintain various insurance coverages to minimize financial risk associated with these proceedings. None of these proceedings, separately or in the aggregate, are expected to have a material adverse effect on our financial position, results of operations or cash flows. With respect to all such proceedings, we record reserves when it is probable that a liability has been incurred and the amount of loss can be reasonably estimated. We expense routine legal costs related to these proceedings as they are incurred. The following is a discussion of our significant legal matters: Capstone Construction Claims From 2003 to 2005, two of our former subsidiaries performed HVAC and electrical work under contract with Capstone Building Corporation (“Capstone”) on a university student housing project in Texas. In 2005, our subsidiaries filed for arbitration against Capstone, seeking payment for work performed, change orders and other impacts. The parties settled those claims, and the release included a waiver of warranties associated with any of the HVAC work. Several years later, the sub sidiaries discontinued operations, and the Company sold their assets. On October 24, 2013, Capstone filed a petition in the 12th Judicial District Court of Walker County, Texas against these subsidiaries, among other subcontractors, seeking contribution, d efense, indemnity and damages for breach of contract in connection with alleged construction defect claims brought against Capstone by the owner of the student housing project. The owner claims $ 10,406 in damages, plus attorneys’ fees and costs against Cap stone, which Capstone is seeking to recover from the subcontractors. The claims against the Company are based on alleged defects in the mechanical design, construction and installation of the HVAC and electrical systems performed by our former subsidiaries . Based on the settlement reached in the 2005 arbitration, we moved for, and the District Court granted us, summary judgment, dismissing all of Capstone’s claims in the 2013 l awsuit. Capstone appealed, and in April , 2016, the 10th Court of Appeals, Waco, T exas Division, reversed the ruling with respect to the indemnity claims and remanded the case back to the District Court. The Texas Supreme Court subsequently denied our petition to review this decision and our motion for rehearing. As a result, we filed a new motion for summary judgment at the District Court level in April 2017 . The Company will defend the claims and expects ultimately to prevail on the merits, but there can be no assurance that the Company will prevail or that it will not incur costs and liability for indemnity in connection with resolution of the claims. To date, the Company has not established a reserve with respect to this matter, as we believe the likelihood of our responsibility for damages is not probable and a potential range of exp osure is not reasonably estimable. Risk-Management We retain the risk for workers’ compensation, employer’s liability, automobile liability, construction defects, general liability and employee group health claims, as well as pollution coverage, resulting from uninsured deductibles per accident or occurrence which are generally subject to annual aggregate limits. Our general liability program provides coverage for bodily injury and property damage. In many cases, we insure third parties, including general contractors, as additional insu reds under our insurance policies. Losses are accrued based upon our known claims incurred and an estimate of claims incurred but not reported. As a result, many of our claims are effectively self-insured. Many claims against our insurance are in the form of litigation. At March 31, 2017 and September 30, 2016 , we had $ 6,198 and $ 5,464 , respectively, accrued for insurance liabilities. We are also subject to construction defect liabilities, primarily within our Residential segment. As of March 31, 2017 and September 30, 2016 , we had $ 219 and $ 235 , respectively, reserved for these claims. Because the reserves are based on judgment and estimates, and involve variables that are inherently uncertain, such as the outcome of litigation and an assessment of insurance coverage, there can be no assurance that the ultimate liability will not be higher or lower than such estimates or that the timing of payments will not create liquidity issues for the Company. Some of the underwriters of our casualty insurance program require us to post letters of credit as collateral. This is common in the insurance industry. To date, we have not had a situation where an underwriter has had reasonable cause to effect payment u nder a letter of credit. At March 31, 2017 and September 30, 2016 , $ 6,176 and $ 6,126 , respectively, of our outstanding letters of credit was utilized to collateralize our insurance program. Surety As of March 31, 2017 , the estimated cost to complete our bonded projects was approximately $ 38,949 . We evaluate our bonding requirements on a regular basis, including the terms offered by our sureties. We believe the bonding capacity presently provided by our current sureties is adequate for our current operations and will be adequate for our operations for the foreseeable future. Posting letters of credit in favor of our sureties reduces the borrowing availability under our credit facility. Other Commitments and Contingencies Some of our customers and vendors require us to post letters of credit, or provide intercompany guarantees, as a means of guaranteeing performance under our contracts and ensuring payment by us to subcontractors and vendors. If our customer has reasonable cause to effect payment under a letter of credit, we would be required to reimburse our creditor for the le tter of credit. At March 31, 2017 and September 30, 2016 , $ 458 and $ 818 , respectively, of our outstanding letters of credit were to collateralize our vendors. From time to time, we may enter into firm pu rchase commitments for materials such as copper or aluminum wire which we expect to use in the ordinary course of business. These commitments are typically for terms of less than one year and require us to buy minimum quantities of materials at specific in tervals at a fixed price over the term. As of March 31, 2017 , we had no such purchase orders.

The total purchase consideration for the Freeman acquisition included contingent consideration payments based on the acquired company’s earnings, as defined in the purchase and sale agreement, through March 31, 2020 . The f air value of the contingent consideration liability was estimated at $ 464 at March 31, 2017 , and is included in other non-current li abilities on our condensed consolidated balance sheets. Freeman is a n Ohio -b ased manufacturer of custom generator enclosures primarily used by data centers and large commercial and industrial facilities. Freeman is included in our Infrastructure Solutions segment. The Company accounted for the transaction under the acquisition method of accounting, which requires recording assets and liabilities at fair value (Level 3). The valuations derived from estimated fair value assessments and assumptions used by management are preliminary, pending finalization of the valuations of deferr ed taxes, fixed assets, contingent consideration liability, and certain intangible assets. While management believes that its preliminary estimates and assumptions underlying the valuations are reasonable, different estimates and assumptions could result i n different values being assigned to individual assets acquired and liabilities assumed. This may result in adjustments to the preliminary amounts recorded. The preliminary valuation of the assets acquired and liabilities assumed as of the date of the acqu isition is as follows: Current assets $ 5,406 Property and equipment 7,581 Intangible assets (primarily customer relationships) 1,989 Goodwill 3,820 Current liabilities (5,508) Deferred tax liability (1,161) Net assets acquired $ 12,127 With regard to goodwill, which is not tax deductible, the balance is attributable to the workforce of the acquired business and other intangibles that do not qualify for separate recognition. 2016 The Company completed four acquisitions in the fiscal year ended September 30, 2016 for total aggregate consideration of $ 59,592 .

SUBSEQUENT EVENTS Credit facility amendment On April 10, 2017, we entered into an amendment and restatement to our revolving credit facility (“the Amended Credit Agreement”) . Pursuant to the Amended Credit Agre ement , our maximum revolver amount increased from $70 million to $100 million, and the maturity date of the revolving credit facility was extended from August 9, 2019 to August 9, 2021. The Amended Credit Agreement also modified our f inancial covenants by, among other items, implementing a new covenant that requires the Company to maintain a minimum EBITDA (as defined in the Amended Credit Agreement) that will be tested quarterly on a trailing twelve month basis; increasing the minimum liquidity requirement applicable to the Company from 12.5% to 30% of the maximum revolver amount; raising the Company’s required fixed charge coverage ratio (the “FCCR”) to 1.1:1.0 from 1.0:1.0; and requiring that the FCCR be tested quarterly regardless o f the Company’s liquidity levels. The amendment and restatement did not include any changes to interest rates and continues to contain other customary affirmative, negative and financial covenants as well as events of default.

LossContingencyOpinionOfCounsel	Based on the settlement reached in the 2005 arbitration, we moved for, and the District Court granted us, summary judgment, dismissing all of Capstone’s claims in the 2013 lawsuit. Capstone appealed, and in April, 2016, the 10th Court of Appeals, Waco, Texas Division, reversed the ruling with respect to the indemnity claims and remanded the case back to the District Court. The Texas Supreme Court subsequently denied our petition to review this decision and our motion for rehearing. As a result, we filed a new motion for summary judgment at the District Court level in April 2017. The Company will defend the claims and expects ultimately to prevail on the merits, but there can be no assurance that the Company will prevail or that it will not incur costs and liability for indemnity in connection with resolution of the claims. To date, the Company has not established a reserve with respect to this matter, as we believe the likelihood of our responsibility for damages is not probable and a potential range of exposure is not reasonably estimable.
