Accounting Policies [Abstract]
Summary of Significant Accounting Policies	(1) Summary of Significant Accounting Policies Description of Business – Layne Christensen Company and subsidiaries (together, “Layne,” the “Company,” “we,” “our,” or “us”) is a global water management, construction and drilling company. We primarily operate in North America and South America. Our customers include government agencies, investor-owned utilities, industrial companies, global mining companies, consulting engineering firms, heavy civil construction contractors, oil and gas companies, power companies and agribusinesses. We have ownership interests in certain foreign affiliates operating in Latin America (see Note 5 to the Consolidated Financial Statements). Fiscal Year – Layne’s fiscal year end is January 31. References to fiscal years, or “FY,” are to the twelve months then ended. Investment in Affiliated Companies – Investments in affiliates (20% to 50% owned) in which we have the ability to exercise significant influence, but do not hold a controlling interest over operating and financial policies, are accounted for by the equity method. We evaluate our equity method investments for impairment at least annually or when events or changes in circumstances indicate there is a loss in value of the investment that is other than a temporary decline. During the fiscal year ended January 31, 2017, due to the extended downturn in the minerals market due to lower commodity prices for the past few years, we reviewed our equity method investments for impairment. Based on weighted approach of the discounted cash flow method and market approach, we concluded that the fair value exceeds the carrying amount of our equity investments. Accordingly, no impairment charge was recorded during the fiscal year ended January 31, 2017. Principles of Consolidation – The Consolidated Financial Statements include the accounts of Layne and all of our subsidiaries where we exercise control. For investments in subsidiaries that are not wholly-owned, but where we exercise control, the equity held by the minority owners and their portions of net income (loss) are reflected as noncontrolling interests. All intercompany accounts and transactions have been eliminated in consolidation. In the Notes to Consolidated Financial Statements, all dollar and share amounts in tabulations are in thousands of dollars and shares, respectively, unless otherwise indicated. Presentation – Beginning with the first quarter of fiscal year ended January 31, 2017, we are excluding nonvested restricted stock units (“RSU”) from the total shares issued and outstanding in our Consolidated Balance Sheets, since no shares are actually issued until the shares have vested and are no longer restricted. Once the restriction lapses on RSUs, the units are converted to unrestricted shares of our common stock and the par value of the stock is reclassified from additional paid-in-capital to common stock. RSU shares in prior periods have been reclassified to conform to this presentation. As discussed further in Note 16 to the Consolidated Financial Statements, during the third quarter of fiscal year ended January 31, 2016, we completed the sale of our Geoconstruction business segment. During the fiscal year ended January 31, 2015, we sold Costa Fortuna and Tecniwell, both previously reported in the Geoconstruction operating segment. The results of operations related to the Geoconstruction business segment have been classified as discontinued operations for all periods presented through the date of sale. Unless noted otherwise, discussion in these Notes to Consolidated Financial Statements pertains to continuing operations. Amounts presented on the Consolidated Balance Sheets have also been reclassified. Business Segments – We report our financial results under four reporting segments consisting of Water Resources, Inliner, Heavy Civil and Mineral Services. During the first quarter of fiscal year ended January 31, 2017, changes were made to simplify our business and streamline our operating and reporting structure. Our Collector Wells group was shifted from Heavy Civil to Water Resources to better align their operational expertise. We also shifted certain other smaller operations out of our “Other” segment and into our four reporting segments, and no longer report an “Other” segment. Information for prior periods has been recast to conform to our new presentation. We also report corporate activities under the title “Unallocated Corporate.” Unallocated corporate expenses primarily consist of general and administrative functions performed on a company-wide basis and benefiting all segments. These costs include accounting, financial reporting, internal audit, treasury, legal, tax compliance, executive management and board of directors. Corporate assets are all assets not directly associated with a segment, and consist primarily of cash and deferred income taxes. Use of and Changes in Estimates – The preparation of financial statements in conformity with accounting principles generally accepted in the U.S. requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Estimates and assumptions about future events and their effects cannot be perceived with certainty, and accordingly, these estimates may change as new events occur, as more experience is acquired, as additional information is obtained and as Layne’s operating environment changes. While we believe that the estimates and assumptions used in the preparation of the Consolidated Financial Statements are appropriate, actual results could differ from those estimates. Foreign Currency Transactions and Translation – In accordance with ASC Topic 830, “Foreign Currency Matters,” gains and losses resulting from foreign currency transactions are included in the Consolidated Statements of Operations. Assets and liabilities of non-U.S. subsidiaries whose functional currency is the local currency are translated into U.S. dollars at exchange rates prevailing at the balance sheet date. The net foreign currency exchange differences resulting from these translations are reported in accumulated other comprehensive loss. Revenues and expenses are translated at average foreign currency exchange rates during the year. The cash flows and financing activities of our operations in Mexico are primarily denominated in U.S. dollars. Accordingly, these operations use the U.S. dollar as their functional currency. Monetary assets and liabilities are remeasured at period end foreign currency exchange rates and nonmonetary items are measured at historical foreign currency exchange rates with exchange rate differences reported in the Consolidated Statement of Operations. Net foreign currency transaction losses were $0.2 million, $0.1 million, and $0.2 million for the fiscal years ended January 31, 2017, 2016 and 2015, respectively, and are recorded in other income, net in the accompanying Consolidated Statements of Operations. Revenue Recognition – Revenues are recognized on large, long-term construction contracts meeting the criteria of ASC Topic 605-35 “Construction-Type and Production-Type Contracts” (“ASC Topic 605-35”), using the percentage-of-completion method based upon the ratio of costs incurred to total estimated costs at completion. Contract price and cost estimates are reviewed periodically as work progresses and adjustments proportionate to the percentage of completion are reflected in contract revenues in the reporting period when such estimates are revised. The nature of accounting for contracts is such that refinements of the estimating process for changing conditions and new developments are continuous and characteristic of the process. Many factors can and do change during a contract performance period which can result in a change to contract profitability including differing site conditions (to the extent that contract remedies are unavailable), the availability of skilled contract labor, the performance of major material suppliers, the performance of major subcontractors, unusual weather conditions and unexpected changes in material costs. These factors may result in revision to costs and income and are recognized in the period in which the revisions become known. Provisions for estimated losses on uncompleted construction contracts are made in the period in which such losses become known. When the estimate on a contract indicates a loss, the entire loss is recorded during the accounting period in which the facts that caused the revision become known. Management evaluates the performance of contracts on an individual basis. In the ordinary course of business, but at least quarterly, we prepare updated estimates of cost and profit or loss for each contract. The cumulative effect of revisions in estimates of the total forecasted revenue and costs, including unapproved change orders and claims, during the course of the contract is reflected in the accounting period in which the facts that caused the revision become known. Large changes in cost estimates on larger, more complex construction projects can have a material impact on our financial statements and are reflected in results of operations when they become known. During the fiscal years ended January 31, 2017, 2016 and 2015, approximately $12.9 million, $22.2 million and $25.2 million in losses on open contracts were recorded, respectively. We record revenue on contracts relating to unapproved change orders and claims by including in revenue an amount less than or equal to the amount of the costs incurred by us to date for contract price adjustments that we seek to collect from customers for delays, errors in specifications or designs, change orders in dispute or unapproved as to scope or price, or other unanticipated additional costs, in each case when recovery of the costs is considered probable. The amount of unapproved change orders and claims revenues are included in our Consolidated Balance Sheets as part of costs and estimated earnings in excess of billings on uncompleted contracts. See Note 2 to the Consolidated Financial Statements. When determining the likelihood of eventual recovery, we consider such factors as our experience on similar projects and our experience with the customer. As new facts become known, an adjustment to the estimated recovery is made and reflected in the current period. As allowed by ASC Topic 605-35, revenue is recognized on smaller, short-term construction contracts using the completed contract method. Provisions for estimated losses on uncompleted construction contracts are made in the period in which such losses become known. We determine when contracts such as these are completed based on acceptance by the customer. Revenues for drilling contracts within Mineral Services are recognized in terms of the value of total work performed to date on the basis of actual footage or meterage drilled. Revenues for direct sales of equipment and other ancillary products not provided in conjunction with the performance of construction contracts are recognized at the date of delivery to, and acceptance by, the customer. Provisions for estimated warranty obligations are made in the period in which the sales occur. Our revenues are presented net of taxes imposed on revenue-producing transactions with our customers, such as, but not limited to, sales, use, value-added and some excise taxes. Inventories – We value inventories at the lower of cost or market. Cost of U.S. inventories and the majority of foreign operations are determined using the average cost method, which approximates FIFO. Inventories consist primarily of supplies and raw materials. Supplies of $18.8 million and $16.8 million and raw materials of $2.3 million and $2.7 million were included in inventories, net of reserves of $0.9 million and $1.2 million, in the Consolidated Balance Sheets as of January 31, 2017 and 2016, respectively. Property and Equipment – Property and equipment (including major renewals and improvements) are recorded at cost less accumulated depreciation. Depreciation is provided using the straight-line method. The useful lives used for the items within each property classification are as follows: Classification Years Buildings 15 - 35 Machinery and equipment 3 - 10 Property and equipment are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Recoverability is evaluated by comparing the carrying value of the assets to the undiscounted associated cash flows. When this comparison indicates that the carrying value of the asset is greater than the undiscounted cash flows, a loss is recognized for the difference between the carrying value and estimated fair value. Fair value is determined based either on market quotes or appropriate valuation techniques. See Note 4 to the Consolidated Financial Statements for a discussion of fixed asset impairments recognized during the fiscal year ended January 31, 2016. As discussed in Note 18 to the Consolidated Financial Statements, during the fiscal year ended January 31, 2016, we implemented a plan to exit our operations in Africa and Australia. As a result of the decision, we determined that it was more likely than not that certain fixed assets will be sold or otherwise disposed of before the end of their estimated useful lives. We recorded charges of approximately $12.9 million and $3.9 million during the fiscal years ended January 31, 2017 and 2016, respectively, to adjust the carrying values of property and equipment in Africa and Australia to estimated fair values, based upon valuation information that includes available third-party quoted prices and appraisals of assets. In calculating the impairment for fiscal year ended January 31, 2017, the carrying amount of the assets included the cumulative currency translation adjustment related to our African and Australian entities. The charges are shown as part of restructuring costs in the Consolidated Statement of Operations. We reflect property as assets held for sale when management, having the authority to approve the action, commits to a plan to sell the asset, the sale is probable within one year, and the asset is available for immediate sale in its present condition. We also consider whether an active program to locate a buyer has been initiated, whether the asset is marketed actively for sale at a price that is reasonable in relation to its current fair value, and whether actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn. Upon designation as asset held for sale, we record the carrying value of each asset at the lower of its carrying value or its estimated fair value, less estimated costs to sell, and cease recording depreciation. During the fourth quarter of the fiscal year ended January 31, 2017, we determined that our assets in Australia amounting to $2.5 million, which is part of Mineral Services segment, met all of the held for sale criteria, and as such were classified as held for sale in the Consolidated Balance Sheet as of January 31, 2017. We recorded a reserve for assets held for sale related to Australia of $12.4 million as of January 31, 2017, and the reserve is included as part of Other Current Liabilities in the Consolidated Balance Sheet. During the fourth quarter of the fiscal year ended January 31, 2016, we determined that assets in our Ethiopian location amounting to $0.8 million, which is part of Mineral Services segment, met all of the held for sale criteria, and as such were classified as held for sale in the Consolidated Balance Sheet as of January 31, 2017 and 2016. During the fourth quarter of the fiscal year ended January 31, 2015, assets in our Redlands, California location amounting to $1.4 million, which is part of the Water Resources segment, were classified as held for sale. Due to unforeseen circumstances, the foregoing sale was not completed during the past two fiscal years; however, the assets continue to meet the held for sale criteria as of January 31, 2017, and disposition is expected to be completed within the next twelve months. Discontinued Operations – We adopted Accounting Standards Update 2014-08, "Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity," on February 1, 2015. Under the new guidance, a discontinued operation is defined as a disposal of a component or group of components that is disposed of or is classified as held for sale and represents a strategic shift that has or will have a major effect on an entity’s operations and financial results. See Note 16 to the Consolidated Financial Statements for a discussion of our discontinued operations. Goodwill –In accordance with ASC Topic 350-20, “Intangibles-Goodwill and Other”, we are required to test for the impairment of goodwill on at least an annual basis. We conduct this evaluation annually as of December 31 or more frequently if events or changes in circumstances indicate that goodwill might be impaired. Our reporting units are based on our organizational and reporting structure and are the same as our four reportable segments. Corporate and other assets and liabilities are allocated to the reporting units to the extent that they relate to the operations of those reporting units in determining their carrying amount. We have the option of first performing a qualitative assessment to determine the existence of events and circumstances that would lead to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If such a conclusion is reached, then we would be required to perform a quantitative impairment assessment of goodwill. However, if the assessment leads to a determination that it is more likely than not that the fair value of a reporting unit is greater than its carrying amount, no further assessments are required. As of December 31, 2016 and 2015, we performed a qualitative assessment for our annual goodwill impairment test, and determined that it was more likely than not that the fair value of Inliner, the only reporting unit with goodwill, would exceed its carrying value . As of January 31, 2017 and 2016, we had $8.9 million of goodwill on the Consolidated Balance Sheets. The goodwill is all attributable to the Inliner reporting segment. Goodwill expected to be tax deductible was $0.9 million as of January 31, 2017 and 2016. The cumulative goodwill impairment losses for Water Resources, Inliner, Heavy Civil and Mineral Services were $17.5 million, $23.1 million, $44.6 million and $20.2 million, respectively, which were recorded during the fiscal year ended January 31, 2012. Intangible Assets – Other intangible assets with finite lives primarily consist of tradenames and patents. Intangible assets are being amortized using the straight-line method over their estimated useful lives, which range from ten to thirty-five years. Finite-lived intangible assets are reviewed for recoverability whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Cash and Cash Equivalents – We consider investments with an original maturity of three months or less when purchased to be cash equivalents. Our cash equivalents are subject to potential credit risk. Our cash management and investment policies restrict investments to investment grade, highly liquid securities. The carrying value of cash and cash equivalents approximates fair value. Restricted Deposits – Restricted deposits consist of escrow funds related to a certain disposition, and judicial deposits associated with tax related legal proceedings in Brazil. Restricted deposits – current of $3.5 million as of January 31, 2016, are included in Other Current Assets in the Consolidated Balance Sheet. Restricted deposits – non-current of $5.0 million and $4.3 million as of January 31, 2017 and 2016, respectively, are included in Other Assets in the Consolidated Balance Sheets. Allowance for Uncollectible Accounts Receivable – We make ongoing estimates relating to the collectability of our accounts receivable and maintain an allowance for estimated losses resulting from the inability of our customers to make required payments. In determining the amount of the allowance, we make judgments about the creditworthiness of customers based on ongoing credit evaluations, and also consider a review of accounts receivable aging, industry trends, customer financial strength, credit standing and payment history to assess the probability of collection. Bad debt expense, which is recorded as part of Selling, General and Administrative Expenses in the Consolidated Statement of Operations, amounted to $1.9 million, ($0.6) million, and $0.8 million for the fiscal years ended January 31, 2017, 2016 and 2015, respectively. We do not establish an allowance for credit losses on long-term contract unbilled receivables. Adjustments to unbilled receivables related to credit quality, if they occur, are accounted for as a reduction of revenue. Concentration of Credit Risk – We grant credit to our customers, which may include concentrations in state and local governments. Although this concentration could affect our overall exposure to credit risk, we believe that our portfolio of accounts receivable is sufficiently diversified, thus spreading the credit risk. To manage this risk, we perform periodic credit evaluations of our customers’ financial condition, including monitoring our customers’ payment history and current credit worthiness. We do not generally require collateral in support of our trade receivables, but may require payment in advance or security in the form of a letter of credit or bank guarantee. During the fiscal years ended January 31, 2017, 2016 and 2015, no individual customer accounted for more than 10% of our consolidated revenues. Accrued Insurance – We maintain insurance programs where we are responsible for the amount of each claim up to a self-insured limit. Estimates are recorded for health and welfare, workers’ compensation, property and casualty insurance costs that are associated with these programs. These costs are estimated based in part on actuarially determined projections of future payments under these programs and include amounts incurred but not reported. Should a greater amount of claims occur compared to what was estimated or costs of the medical profession increase beyond what was anticipated, accruals recorded may not be sufficient and additional costs to the consolidated financial statements could be required. Costs estimated to be incurred in the future for employee health and welfare benefits, workers’ compensation, property and casualty insurance programs resulting from claims which have been incurred are accrued currently. Under the terms of the agreement with the various insurance carriers administering these claims, we are not required to remit the total premium until the claims are actually paid by the insurance companies. Fair Value of Financial Instruments – The carrying amounts of financial instruments, including cash and cash equivalents, customer receivables and accounts payable, approximated fair value at January 31, 2017 and 2016, because of the relatively short maturity of those instruments. See Note 14 to the Consolidated Financial Statements for fair value disclosures. Litigation and Other Contingencies – We are involved in litigation incidental to our business, the disposition of which is not expected to have a material effect on our business, financial position, results of operations or cash flows. In addition, some of our contracts contain provisions that require payment of liquidated damages if we are responsible for the failure to meet specified contractual milestone dates and the applicable customer asserts a claim under these provisions. These contracts define the conditions under which our customers may make claims against Layne for liquidated damages. In many cases in which we have historically had potential exposure for liquidated damages, such damages ultimately were not asserted by our customers. It is possible, however, that future results of operations for any particular quarterly or annual period could be materially affected by changes in our assumptions related to these proceedings. If the assessment of a contingency indicates that it is probable that a material loss has been incurred and the amount of the liability can be estimated, then the estimated liability is accrued in our Consolidated Financial Statements. If the assessment indicates that a potentially material loss contingency is not probable but is reasonably possible, or is probable but cannot be estimated, then the nature of the contingent liability, and an estimate of the range of possible losses, if determinable and material, is disclosed. These provisions are reviewed at least quarterly and adjusted to reflect the impacts of negotiations, settlements, rulings, advice of legal counsel, and other information and events pertaining to a particular case. Supplemental Cash Flow Information –The amounts paid or refunded for income taxes, interest and non-cash investing and financing activities were as follows: Years Ended January 31, (in thousands) 2017 2016 2015 Income taxes paid $ 1,555 $ 1,947 $ 3,882 Income tax refunds (596 ) (4,251 ) (394 ) Interest paid 12,331 11,065 6,737 Noncash investing and financing activities: Exchange of 4.25% Convertible Notes for 8.0% Convertible Notes — 55,500 — Contingent consideration on sale of discontinued operations — 4,244 — Receivable on sale of discontinued operations — — 2,638 Accrued capital additions 1,427 1,186 774 Income Taxes – Income taxes are provided using the asset and liability method, in which deferred taxes are recognized on the difference between the financial statement carrying amounts and tax bases of existing assets and liabilities. Deferred tax assets are reviewed for recoverability and valuation allowances are provided as necessary. Provision for U.S. income taxes on undistributed earnings of foreign subsidiaries and affiliates is made only on those amounts in excess of funds considered to be invested indefinitely. In general, we record income tax expense during interim periods based on our best estimate of the full year’s effective tax rate. However, income tax expense relating to adjustments to Layne’s liabilities for uncertainty in income tax positions for prior reporting periods are accounted for discretely in the interim period in which it occurs. Income tax expense relating to adjustments for current year uncertain tax positions is accounted for as a component of the adjusted annualized effective tax rate. In assessing the need for a valuation allowance, we consider both positive and negative evidence related to the likelihood of realization of the deferred tax assets. The weight given to the positive and negative evidence is commensurate with the extent to which the evidence may be objectively verified. Accounting guidance states that a cumulative loss in recent years is a significant piece of negative evidence that is difficult to overcome in determining that a valuation allowance is not needed against deferred tax assets. As such, it is generally difficult for positive evidence regarding projected future taxable income exclusive of reversing taxable temporary differences to outweigh objective negative evidence of recent financial reporting losses. In preparing future taxable income projections, we consider the periods in which future reversals of existing taxable and deductible temporary differences are likely to occur, future taxable income, taxable income available in prior carryback years and the availability of tax-planning strategies when determining the ability to realize recorded deferred tax assets. Our estimate of uncertainty in income taxes is based on the framework established in the accounting for income taxes guidance. We recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. For tax positions that meet this recognition threshold, we apply judgment, taking into account applicable tax laws and experience in managing tax audits, to determine the amount of tax benefits to recognize in the financial statements. For each position, the difference between the benefit realized on our tax return and the benefit reflected in the financial statements is recorded as a liability in the Consolidated Balance Sheets. This liability is updated at each financial statement date to reflect the impacts of audit settlements and other resolution of audit issues, expiration of statutes of limitation, developments in tax law and ongoing discussions with taxing authorities. Income (Loss) Per Share – Income (loss) per share is computed by dividing net earnings available to common shareholders by the weighted average number of common shares outstanding during the period. For periods in which we recognize losses, the calculation of diluted loss per share is the same as the calculation of basic loss per share. For periods in which we recognize net income, diluted earnings per common share is computed in the same way as basic earnings per common share except that the denominator is increased to include the number of additional common shares that would be outstanding if all potential common shares had been issued that were dilutive. Options to purchase common stock and nonvested shares are included based on the treasury stock method for dilutive earnings per share except when their effect is antidilutive. The 4.25% Convertible Notes and the 8.0% Convertible Notes (as defined in Note 8 to the Consolidated Financial Statements) are included in the calculation of diluted loss per share if their inclusion is dilutive under the if-converted method. Options to purchase 750,044, 839,715 and 1,015,514 shares have been excluded from weighted average shares for the fiscal years ended January 31, 2017, 2016 and 2015, respectively, as their effect was antidilutive. A total of 1,871,640, 1,407,170 and 487,292 non-vested shares have been excluded from weighted average shares for the fiscal years ended January 31, 2017, 2016 and 2015, respectively, as their effect was antidilutive. Share-Based Compensation – We recognize the cost of all share-based instruments in the financial statements based on the calculated fair value of the award. The fair value of share-based compensation granted in the form of stock options is determined using a lattice valuation model. In addition, we granted certain market-based awards during the years ended January 31, 2017, 2016 and 2015, which were valued using the Monte Carlo simulation model. See Note 13 to the Consolidated Financial Statements. Unearned compensation expense associated with the issuance of awards is amortized on a straight-line basis as the restrictions on the stock expire, subject to achievement of certain contingencies. Research and Development Costs – Research and development costs charged to expense during the fiscal years ended January 31, 2017, 2016 and 2015 were $0.1 million in each of the three fiscal years and are recorded in selling, general and administrative expenses.

Goodwill And Intangible Assets Disclosure [Abstract]
Impairment Charges	(4) Impairment Charges Prior to the segment realignment in the third quarter of the fiscal year ended January 31, 2016, we reviewed the recoverability of the asset values of our long-lived assets in the Energy Services segment during the second quarter of the fiscal year ended January 31, 2016. Using the undiscounted cash flow model, we concluded that the carrying value of the assets in Energy Services was not fully recoverable as of July 31, 2015. We performed an assessment of the fair value of the assets of Energy Services based on orderly liquidation value of the property and equipment, which was considered as Level 2 fair value measurement. This assessment resulted in the recording of an impairment charge of approximately $4.6 million during the second quarter of the fiscal year ended January 31, 2016, which is shown as impairment charges in the Consolidated Statements of Operations.

The asset-based facility is guaranteed by assets of our direct and indirect wholly owned domestic subsidiaries, subject to certain exceptions described in the asset-based facility. The obligations under the asset-based facility are secured by a lien on substantially all of our assets and the assets of the subsidiary guarantors, subject to certain exceptions described in the asset-based facility, including a pledge of up to 65% of the equity interests of our first tier foreign subsidiaries. Availability under the asset-based facility is currently the lesser of (i) $100.0 million or (ii) the borrowing base (as defined in the asset-based facility agreement). Availability under the asset-based facility as of January 31, 2017, was approximately $100.0 million, as the borrowing base exceeded total commitments. Approximately $27.7 million of letters of credit were issued under the asset-based facility as of January 31, 2017, resulting in Excess Availability (described below) of $72.3 million. Advances under the asset-based facility are subject to certain conditions precedent, including the accuracy of certain representations and warranties and the absence of any default or event of default. Future advances may be used for general corporate and working capital purposes, and to pay fees and expenses associated with the asset-based facility. Pursuant to the asset-based facility agreement, the revolving loans will bear interest at either: • the alternate base rate plus the applicable margin. The alternate base rate is equal to the highest of (a) the base rate, (b) the sum of the Federal Funds Open rate plus 0.5%, and (c) the sum of the Daily LIBOR rate plus 1%, or • the LIBOR rate (as defined in the asset-based facility agreement) for the interest period in effect for such borrowing plus the applicable margin. The asset-based facility contains various restrictions and covenants, including restrictions on dispositions of certain assets, incurrence of indebtedness, investments, distributions, capital expenditures, acquisitions and prepayment of certain indebtedness. In general, provided that we maintain a certain level of Excess Availability, we will not be restricted from incurring additional unsecured indebtedness or making investments, distributions, capital expenditures or acquisitions. In compliance with the terms of our asset-based facility, we obtained an asset sale consent from our lenders on January 25, 2017 in connection with the sale of our Heavy Civil business segment. If Excess Availability is less than the greater of 17.5% of Total Availability or $17.5 million for more than one business day, then a “Covenant Compliance Period” (as defined in the asset-based facility agreement) will exist until Excess Availability has been equal to or greater than the greater of 17.5% of the Total Availability or $17.5 million for a period of 30 consecutive days. We must maintain a minimum fixed charge coverage ratio of not less than 1.0 to 1.0 and a maximum first lien leverage ratio of not greater than 5.0 to 1.0 for the four fiscal quarters ended immediately preceding any Covenant Compliance Period and for any four fiscal quarter period ending during a Covenant Compliance Period. We would not have been in compliance with the fixed charge coverage ratio had we been in a Covenant Compliance Period as of the fiscal years ended January 31, 2017 and 2016. During the fiscal year ended January 31, 2016, we had two consecutive four-quarter periods with a fixed charge coverage ratio of not less than 1.0 to 1.0 and therefore, we are no longer required to maintain a cumulative minimum cash flow (as defined in the asset-based facility agreement) of not less than negative $45.0 million and a minimum cash flow of not less than negative $25.0 million during any twelve consecutive month period. The asset-based facility also contains a subjective acceleration clause that can be triggered if the lenders determine that we have experienced a material adverse change. If triggered by the lenders, this clause would create an Event of Default (as defined in the asset-based facility agreement), which in turn would permit the lenders to accelerate repayment of outstanding obligations. The balance sheet classification of the borrowings under the asset-based facility has been determined in accordance with ASC Topic 470-10-45, “Balance Sheet Classification of Borrowings Outstanding under Revolving Credit Agreements that Include both a Subjective Acceleration Clause and a Lock-Box Arrangement.” Accordingly, the borrowings have been classified as a long-term liability in the accompanying Consolidated Balance Sheet. In general, during a Covenant Compliance Period or if an Event of Default has occurred and is continuing, all of Layne’s funds received on a daily basis will be applied to reduce amounts owing under the asset-based facility. Based on current projections Layne does not anticipate being in a Covenant Compliance Period during the next twelve months. Also, because Excess Availability currently is, and is expected to be for the next twelve months, sufficient not to trigger a Covenant Compliance Period, we are and anticipate being in compliance with the applicable debt covenants associated with the asset-based facility for the next twelve months. Defaults under the asset-based facility include (but are not limited to) the following: • non-payment of principal, interest, fees and other amounts under the asset-based facility • failure to comply with any of the negative covenants, certain of the specified affirmative covenants or other covenants under the asset-based facility • failure to pay certain indebtedness when due • specified events of bankruptcy and insolvency • one or more judgments of $5.0 million not covered by insurance and not paid within a specified period. • a change in control as defined in the asset-based facility. The maturity date for the asset based facility is April 15, 2019. However, the maturity date will accelerate to May 15, 2018 if each of the following has not yet occurred on or before such date: (i) either (a) all of the 8.0% Convertible Notes (or Permitted Refinancing Indebtedness (as defined in the asset-based facility agreement) in respect thereof) are converted or (b) the maturity date of the 8.0% Convertible Notes (or Permitted Refinancing Indebtedness in respect thereof) is extended to a date which is after October 15, 2019, and (ii) either (a) all of the 4.25% Convertible Notes (or Permitted Refinancing Indebtedness in respect thereof) are converted, (b) the maturity date for the 4.25% Convertible Notes (or Permitted Refinancing Indebtedness in respect thereof) is extended to a date which is after October 15, 2019, or (c) the 4.25% Convertible Notes are effectively discharged. The 4.25% Convertible Notes will be effectively discharged after, among other things, we have irrevocably deposited with the trustee of the 4.25% Convertible Notes cash in an amount sufficient to pay any remaining interest and principal payments due on any then remaining unconverted 4.25% Convertible Notes, with irrevocable instructions to the trustee to make such payments to the holders of the 4.25% Convertible Notes as they become due. 4.25% Convertible Senior Notes On November 12, 2013, we completed the issuance and sale of $110.0 million aggregate principal amount of 4.25% Convertible Notes due 2018 (the “4.25% Convertible Notes”), in accordance with the terms of the purchase agreement (the “Purchase Agreement”) entered into with Jefferies LLC (the “Initial Purchaser”). On December 5, 2013, the Initial Purchaser exercised its option to purchase an additional $15.0 million aggregate principal amount of 4.25% Convertible Notes as part of the Purchase Agreement. The 4.25% Convertible Notes were issued pursuant to an Indenture, dated November 12, 2013 (the “4.25% Convertible Notes Indenture”), between Layne and U.S. Bank National Association, as trustee. The 4.25% Convertible Notes are senior, unsecured obligations of Layne. The 4.25% Convertible Notes are convertible, at the option of the holders, into consideration consisting of, at our election, cash, shares of our common stock, or a combination of cash and shares of our common stock (and cash in lieu of fractional shares) until the close of business on the scheduled trading day immediately preceding May 15, 2018. However, before May 15, 2018, the 4.25% Convertible Notes will not be convertible except in certain circumstances provided in the 4.25% Convertible Notes Indenture. The 4.25% Convertible Notes bear interest at a rate of 4.25% per year, payable semi-annually in arrears in cash on May 15 and November 15 of each year, beginning on May 15, 2014. The 4.25% Convertible Notes will mature on November 15, 2018, unless earlier repurchased, redeemed or converted. The initial conversion rate was 43.6072 shares of our common stock per $1,000 principal amount of 4.25% Convertible Notes (which is equivalent to an initial conversion price of approximately $22.93 per share of our common stock). The conversion rate will be subject to adjustment upon the occurrence of certain events. In addition, we may be obligated to increase the conversion rate for any conversion that occurs in connection with certain corporate events, including our call of the 4.25% Convertible Notes for redemption. On and after November 15, 2016, and prior to the maturity date, pursuant to the 4.25% Convertible Note Indenture, we may redeem all, but not less than all, of the 4.25% Convertible Notes for cash if the sale price of our common stock equals or exceeds 130% of the applicable conversion price for a specified time period ending on the trading day immediately prior to the date we deliver notice of the redemption. The redemption price will equal 100% of the principal amount of the 4.25% Convertible Notes to be redeemed, plus any accrued and unpaid interest to, but excluding, the redemption date. In addition, upon the occurrence of a fundamental change (as defined in the 4.25% Convertible Notes Indenture), holders of the 4.25% Convertible Notes will have the right, at their option, to require us to repurchase their 4.25% Convertible Notes in cash at a price equal to 100% of the principal amount of the 4.25% Convertible Notes to be repurchased, plus accrued and unpaid interest to, but excluding, the fundamental change repurchase date. If any amount payable on a 4.25% Convertible Note (including principal, interest, a fundamental change repurchase or a redemption) is not paid by us when it is due and payable, such amount will accrue interest at a rate equal to 5.25% per annum from such payment date until paid. In accordance with ASC Topic 470-20, “Debt with Conversion and Other Options,” we separately account for the liability and equity conversion components of the 4.25% Convertible Notes. The principal amount of the liability component of the 4.25% Convertible Notes was $106.0 million as of the date of issuance based on the present value of our cash flows using a discount rate of 8.0%, our approximate borrowing rate at the date of the issuance for a similar debt instrument without the conversion feature. The carrying value of the equity conversion component was $19.0 million. A portion of the Initial Purchaser’s discount and commission and the offering costs totaling $0.8 million and deferred taxes totaling $7.1 million were allocated to the equity conversion component. The liability component will be accreted to the principal amount of the 4.25% Convertible Notes using the effective interest method over five years. In accordance with guidance in ASC Topic 470-20 and ASC Topic 815-15, “Embedded Derivatives,” we determined that the embedded conversion components and other embedded derivatives of the 4.25% Convertible Notes do not require bifurcation and separate accounting. On March 2, 2015, we exchanged approximately $55.5 million aggregate principal amount of our 4.25% Convertible Notes for approximately $49.9 million aggregate principal amount of our 8.0% Convertible Notes (described further below). In accordance with the derecognition guidance for convertible instruments in an exchange transaction under ASC Topic 470-20, the fair value of the 8.0% Convertible Notes (“the exchange consideration”) and the transaction costs incurred were allocated between the liability and equity components of the 4.25% Convertible Notes. Of the $49.9 million exchange consideration, $42.1 million, which represents the fair value of the 4.25% Convertible Notes immediately prior to its derecognition, was allocated to the extinguishment of the liability component. Transaction costs of $0.9 million were also allocated to the liability component. As a result, we recognized a gain on extinguishment of debt of $4.2 million during the first quarter of the fiscal year ended January 31, 2016. The remaining $7.8 million of the exchange consideration and $0.2 million of transaction costs were allocated to the reacquisition of the equity component and recognized as a reduction of stockholders’ equity. The following table presents the carrying value of the 4.25% Convertible Notes: January 31, January 31, (in thousands) 2017 2016 Carrying amount of the equity conversion component $ 3,106 $ 3,106 Principal amount of the 4.25% Convertible Notes $ 69,500 $ 69,500 Unamortized deferred financing fees (1,033 ) (1,523 ) Unamortized debt discount (1) (4,080 ) (6,211 ) Net carrying amount $ 64,387 $ 61,766 (1) As of January 31, 2017, the remaining period over which the unamortized debt discount will be amortized is 21 months using an effective interest rate of 9%. 8.0 % Senior Secured Second Lien Convertible Notes On March 2, 2015, we completed the offering of approximately $100.0 million aggregate principal amount of 8.0% Senior Secured Second Lien Convertible Notes (“8.0% Convertible Notes”). The 8.0% Convertible Notes were offered at par to certain investors that held approximately $55.5 million of our 4.25% Convertible Notes due 2018 pursuant to terms in which the investors agreed to (i) exchange the 4.25% Convertible Notes owned by them for approximately $49.9 million of the 8.0% Convertible Notes and (ii) purchase approximately $49.9 million aggregate principal amount of 8.0% Convertible Notes at a cash price equal to the principal amount thereof. The amount of accrued interest on the 4.25% Convertible Notes delivered by the investors in the exchange was credited to the cash purchase price payable by the investors in the purchase. The sale of the 8.0% Convertible Notes generated net cash proceeds of approximately $45.0 million after deducting discounts and commissions, estimated offering expenses and accrued interest on the 4.25% Convertible Notes being exchanged. We used the net cash proceeds to repay the then outstanding balance on the asset-based facility of $18.2 million with the remainder of the proceeds held for general working capital purposes. The 8.0% Convertible Notes were issued pursuant to an Indenture, dated as of March 2, 2015 (the “8.0% Convertible Notes Indenture”), among Layne, the guarantor parties thereto and U.S. Bank National Association, as trustee and collateral agent. The 8.0% Convertible Notes are senior, secured obligations of Layne, with interest payable on May 1 and November 1 of each year, beginning May 1, 2015, at a rate of 8.0% per annum. The 8.0% Convertible Notes will mature on May 1, 2019; provided, however, that, unless all of the 4.25% Convertible Notes (or any permitted refinancing indebtedness in respect thereof) have been redeemed, repurchased, otherwise retired, discharged in accordance with their terms or converted into our common stock, or have been effectively discharged, in each case on or prior to August 15, 2018 or the scheduled maturity date of the 4.25% Convertible Notes (or any permitted refinancing indebtedness incurred in respect thereof) is extended to a date that is after October 15, 2019, the 8.0% Convertible Notes will mature on August 15, 2018. The 8.0% Convertible Notes are senior, secured obligations and are guaranteed by our subsidiaries that currently are co-borrowers or guarantors under our asset-based facility, as well as all of our future wholly-owned U.S. restricted subsidiaries and, in certain cases, certain of our other subsidiaries. The 8.0% Convertible Notes are secured by a lien on substantially all of our assets and the assets of the subsidiary guarantors, subject to certain exceptions. The liens on the assets securing the 8.0% Convertible Notes are junior in priority to the liens (the “First Priority Liens”) on such assets securing our debt (the “First Priority Debt”) or that of the subsidiary guarantors under our asset-based facility and certain other specified existing or future obligations. At any time prior to the maturity date, we may redeem for cash all, but not less than all, of the 8.0% Convertible Notes; provided, however, that we may not redeem the 8.0% Convertible Notes on a redemption date that is outside an Open Redemption Period (as defined in the 8.0% Convertible Notes Indenture) unless the last reported sale price of our common stock equals or exceeds 140% of the conversion price of the 8.0% Convertible Notes in effect on each of at least 20 trading days during the 30 consecutive trading day period ending on, and including, the trading day immediately preceding the date on which we deliver the redemption notice. In addition, upon the occurrence of a “fundamental change” (as defined in the 8.0% Convertible Notes Indenture), holders of the 8.0% Convertible Notes will have the right, at their option, to require us to repurchase their 8.0% Convertible Notes in cash at a price equal to 100% of the principal amount of the 8.0% Convertible Notes to be repurchased, plus accrued and unpaid interest to, but excluding, the fundamental change repurchase date. The 8.0% Convertible Notes Indenture permits us to reinvest the net proceeds from certain “asset sales” (as defined in the 8.0% Convertible Notes Indenture). Any such reinvestments are subject to the criteria and time periods in the 8.0% Convertible Notes Indenture. Any net proceeds from “asset sales” that are not reinvested within the applicable time period constitute “excess proceeds” (as defined in the 8.0% Convertible Notes Indenture). When the aggregate amount of “excess proceeds” exceeds $10.0 million, we must, within 30 days, make an offer to all holders of the 8.0% Convertible Notes and holders of certain other pari passu debt obligations of the Company (together, the “Qualifying Indebtedness”) to repurchase the Qualifying Indebtedness up to the maximum amount of the available “excess proceeds.” The Qualifying Indebtedness repurchase price will equal 100% of the principal amount plus any accrued and unpaid interest to, but excluding the repurchase date. The holders of the Qualifying Indebtedness may, at their option, elect to accept the repurchase offer. If the aggregate amount of Qualifying Indebtedness tendered for repurchase exceeds the amount of “excess proceeds”, the Qualifying Indebtedness tendered will be repurchased on a pro rata basis. We may use any “excess proceeds” remaining as a result of an insufficient amount of Qualifying Indebtedness being tendered for repurchase for any purpose not otherwise prohibited by the 8.0% Convertible Notes Indenture. The 8.0% Convertible Notes are convertible, at the option of the holders, into consideration consisting of shares of our common stock (and cash in lieu of fractional shares) until the close of business on the scheduled trading day immediately preceding the maturity date. No holder will have the right to convert any 8.0% Convertible Notes into shares of common stock to the extent that the conversion would cause that holder to beneficially own more than 9.9% of the shares of our common stock then outstanding after giving effect to the proposed conversion. The initial conversion rate was 85.4701 shares of our common stock per $1,000 principal amount of 8.0% Convertible Notes (equivalent to an initial conversion price of approximately $11.70 per share of our common stock). The conversion rate is subject to adjustment upon the occurrence of certain events. In addition, we may be obligated to increase the conversion rate for any conversion that occurs in connection with certain corporate events, including our call of the 8.0% Convertible Notes for redemption. The 8.0% Convertible Notes Indenture contains covenants that, among other things, restrict our ability and that of our restricted subsidiaries, subject to certain exceptions, to: (1) incur additional indebtedness; (2) create liens; (3) declare or pay dividends on, make distributions with respect to, or purchase or redeem, our equity interests or the equity interests of our restricted subsidiaries, or make certain payments on subordinated or unsecured indebtedness or make certain investments; (4) enter into certain transactions with affiliates; (5) engage in certain asset sales unless specified conditions are satisfied; and (6) designate certain subsidiaries as unrestricted subsidiaries. The 8.0% Convertible Notes Indenture also contains events of default after the occurrence of which the 8.0% Convertible Notes may be accelerated and become immediately due and payable. If any amount payable on a 8.0% Convertible Note (including principal, interest, a fundamental change repurchase or a redemption) is not paid by us when it is due and payable, such amount will accrue interest at a rate equal to 9.0% per annum from such payment date until paid. In accordance with guidance in ASC Topic 815-15, we determined that the embedded conversion components and other embedded derivatives of the 8.0% Convertible Notes do not require bifurcation and separate accounting. We accounted for the 8.0% Convertible Notes as debt with conversion features that are not beneficial under ASC Topic 470-20. Accordingly, all the proceeds from the issuance of the 8.0% Convertible Notes are recorded as a liability in our Consolidated Balance Sheets. The following table presents the carrying value of the 8.0% Convertible Notes: January 31, January 31, (in thousands) 2017 2016 Principal amount of the 8.0% Convertible Notes $ 99,898 $ 99,898 Unamortized deferred financing fees (1,946 ) (2,693 ) Net carrying amount $ 97,952 $ 97,205 Surety Bonds As of January 31, 2017 and 2016, surety bonds issued to secure performance of our projects amounted to $223.8 million and $259.7 million, respectively. The amount of our surety bonds is based on the expected amount of revenues remaining to be recognized on the projects.

See Note 15 to the Consolidated Financial Statements. The tax effect on pretax loss from continuing operations generally is determined by a computation that does not consider the tax effect on other categories of income or loss (for example, other comprehensive loss, discontinued operations, additional paid in capital, etc.). An exception to that general rule is provided when there is a pretax loss from continuing operations and pretax income from other categories of income. Pursuant to this exception, we recorded a tax benefit on continuing operations during the fiscal year ended January 31, 2016. During the fiscal year ended January 31, 2016, a tax benefit of $3.6 million was recorded on continuing operations which offset tax expense recorded on discontinued operations. We recorded $19.4 million, $35.1 million and $26.0 million of valuation allowances from continuing operations on our net domestic and certain foreign deferred tax assets during the fiscal years ended January 31, 2017, 2016 and 2015, respectively. The valuation allowance recorded for the fiscal year ended January 31, 2017 was recorded on deferred tax assets generated during the year, and was primarily related to tax losses and tax credit carryforwards. The total valuation allowance at January 31, 2017 of $157.7 million was comprised of a domestic valuation allowance of $140.3 million and a foreign valuation allowance of $17.4 million. In assessing the need for a valuation allowance, we concluded that we had a cumulative loss on domestic operations after adjusting for significant non-recurring charges beginning in the fiscal year ended January 31, 2014 and continuing through the fiscal year ended January 31, 2017. Based on this assessment, we concluded that it was not more likely than not that realization of our domestic deferred tax assets would occur in future periods, and accordingly a valuation allowance was provided. Similar consideration was given to foreign deferred tax assets, and we concluded that certain foreign deferred tax assets were also not more likely than not to be realized and a valuation allowance was recorded. The establishment of a valuation allowance does not have any impact on cash, nor does such an allowance preclude us from using our loss carryforwards or utilizing other deferred tax assets in the future. The net income (loss) from discontinued operations for the fiscal years ended January 31, 2016 and 2015 was $8.1 million and ($46.9) million, respectively. These amounts are net of income tax (expense) benefit of ($3.6) million, and ($0.7) million, respectively. The effective tax rates for discontinued operations were (31.1%) and 1.5% for the fiscal years ended January 31, 2016 and 2015, respectively. Deferred income taxes result from temporary differences between the financial statement and tax bases of our assets and liabilities. The sources of these differences and their cumulative tax effects were as follows: Years Ended January 31, (in thousands) 2017 2016 Accruals $ 24,719 $ 29,734 Share based compensation 2,525 2,415 Intangibles 3,429 4,039 Foreign tax credit carryforwards 47,827 45,809 Tax loss carryforwards 70,966 49,154 Cumulative currency translation adjustment 5,068 6,588 Capital loss carryforwards 12,861 13,398 Other assets 1,418 2,330 Total deferred tax asset 168,813 153,467 Valuation allowance (157,664 ) (140,124 ) Buildings, machinery and equipment (6,687 ) (6,519 ) Convertible Notes (1,530 ) (2,422 ) Unremitted foreign earnings (4,782 ) (6,593 ) Other liabilities (2,107 ) (2,412 ) Total deferred tax liability (15,106 ) (17,946 ) Net deferred tax liability $ (3,957 ) $ (4,603 ) We had the following tax losses and tax credit carryforwards at January 31, 2017: Gross Expected Tax Carryforward Benefit Valuation (dollars in millions) Expiration Amount Amount Allowance Federal net operating loss carryforwards 2034-2037 $ 131.8 $ 45.4 $ (45.4 ) State net operating loss carryforwards 2024-2037 205.0 10.5 (10.5 ) Federal capital loss carryforwards 2020 33.3 12.9 (12.9 ) State capital loss carryforwards 2020 33.3 1.3 (1.3 ) Foreign tax loss carryforwards 2019-2032 50.2 15.0 (15.0 ) Federal foreign tax credit carryforwards 2018-2022 n/a 20.0 (20.0 ) Federal foreign tax credit carryforwards 2023-2027 n/a 27.8 (27.8 ) Total $ 132.9 $ (132.9 ) As of January 31, 2017, undistributed earnings of foreign subsidiaries and certain foreign affiliates included $44.4 million for which no federal income or foreign withholding taxes have been provided. These earnings, which are considered to be invested indefinitely, would become subject to income tax if they were remitted as dividends or if we were to sell our stock in the affiliates or subsidiaries. It is not practicable to determine the amount of income or withholding tax that would be payable upon remittance of these earnings. Deferred income taxes were provided on undistributed earnings of certain foreign subsidiaries and foreign affiliates where the earnings are not considered to be invested indefinitely. A reconciliation of the beginning and ending amount of gross unrecognized tax benefits, excluding penalties and interest is as follows: Years Ended January 31, (in thousands) 2017 2016 2015 Balance, beginning of year $ 10,809 $ 13,018 $ 15,312 Additions based on tax positions related to current year 7,354 81 187 Additions for tax positions of prior years 1,669 1,326 28 Settlement with tax authorities (1,168 ) — (707 ) Reductions for tax positions of prior years (55 ) (3,392 ) (308 ) Reductions due to the lapse of statutes of limitation (160 ) (224 ) (1,494 ) Balance, end of year $ 18,449 $ 10,809 $ 13,018 Substantially all of the unrecognized tax benefits recorded at January 31, 2017, 2016 and 2015 would affect the effective rate if recognized. It is reasonably possible that the amount of unrecognized tax benefits will decrease during the next year by approximately $7.2 million due to settlements of audit issues and expiration of statutes of limitation. We classify interest and penalties related to income taxes as a component of income tax expense. As of January 31, 2017, 2016 and 2015, we had $8.7 million, $7.8 million and $8.5 million, respectively, of interest and penalties accrued associated with unrecognized tax benefits. The liability for interest and penalties increased (decreased) $0.9 million, ($0.7) million and $0.1 million during the fiscal years ended January 31, 2017, 2016 and 2015, respectively. We file income tax returns in the U.S., various state jurisdictions and certain foreign jurisdictions. The statute of limitations remains open for tax years ended January 31, 2013 through 2017. We are currently under examination for federal purposes for the tax year ended January 31, 2013, and there are several state examinations currently in progress. We file income tax returns in the foreign jurisdictions where we operate. The returns are subject to examination which may be ongoing at any point in time. Tax liabilities are recorded based on estimates of additional taxes which will be due upon settlement of those examinations. The tax years subject to examination by foreign tax authorities vary by jurisdiction, but generally the tax years 2014 through 2017 remain open to examination.

Operating Lease Obligations	(11) Operating Lease Obligations Our operating leases are primarily for buildings, light and medium duty trucks, and other equipment. We sublease certain portion of our facilities under non-cancelable sublease agreements. Rent expense under operating leases (including insignificant amounts of contingent rental payments and sublease rental income) was $4.9 million, $7.3 million and $9.6 million for the fiscal years ended January 31, 2017, 2016 and 2015, respectively. Future minimum lease payments required under operating leases that have initial or remaining non-cancelable lease terms and related subleases in excess of one year from January 31, 2017, are as follows: Minimum Rental (in thousands) Commitments Fiscal Year 2018 $ 3,734 Fiscal Year 2019 2,728 Fiscal Year 2020 2,231 Fiscal Year 2021 1,691 Fiscal Year 2022 1,085 Minimum lease payments $ 11,469

Employee Benefit Plans

Employee Benefit Plans	12 Months Ended
	Jan. 31, 2017
Postemployment Benefits [Abstract]
Employee Benefit Plans	(12) Employee Benefit Plans Our salaried and certain hourly employees are eligible to participate in our sponsored, defined contribution plans. Total expense recorded in selling, general and administrative costs for our portion of these plans was $3.1 million, $3.0 million and $3.2 million for the fiscal years ended January 31, 2017, 2016 and 2015, respectively. We have a deferred compensation plan for certain management employees, however the plan was suspended during the fiscal year ended January 31, 2015. Participants could elect to defer up to 25% of their salaries and up to 50% of their bonuses to the plan. Matching contributions, and the vesting period of those contributions, were established at our discretion. Employee deferrals are vested at all times. The total amount deferred, including matching, for the fiscal year ended January 31, 2015 was $0.2 million. The total liability for deferred compensation was $5.1 million and $6.3 million as of January 31, 2017 and 2016, respectively. These liabilities are primarily included in other non-current liabilities, except for those amounts due in the next twelve months, which are recorded in accrued compensation in the Consolidated Balance Sheet. We contribute to a number of multiemployer defined benefit pension plans under the terms of collective-bargaining agreements that cover our union-represented employees. The risks of participating in these multiemployer plans are different from single-employer plans in the following aspects: • assets contributed to the multiemployer plan by one employer may be used to provide benefits to employees of other participating employers; • if a participating employer stops contributing to the plan, the unfunded obligations of the plan may be borne by the remaining participating employers; and • if we choose to stop participating in some of our multiemployer plans, we may be required to pay those plans an amount based on the underfunded status of the plan, referred to as a withdrawal liability. In accordance with accounting guidance, we evaluated each of our multiemployer plans to determine if any were individually significant. The evaluation was based on the following criteria: • the total employees participating in the multiemployer plan compared to the total employees covered by the plan; • the total contributions to the multiemployer plan as a percentage of the total contributions to the plan by all participating employers; and • the amount of potential liability that could be incurred due to our withdrawal from the multiemployer plan, underfunded status of the plan or other participating employers’ withdrawal from the plan. As of January 31, 2017 and 2016, we did not participate in multiemployer plans that would be considered individually significant. We make contributions to these multiemployer plans equal to the amounts accrued for pension expense. Total contributions and union pension expense for these plans was $1.9 million, $2.1 million and $1.9 million for the fiscal years ended January 31, 2017, 2016 and 2015, respectively. Information regarding assets and accumulated benefits of these plans has not been made available to us. We also provide supplemental retirement benefits to a former chief executive officer. Benefits are computed based on the compensation earned during the highest five consecutive years of employment reduced for a portion of Social Security benefits and an annuity equivalent of his defined contribution plan balance. We do not contribute to the plan or maintain any investment assets related to the expected benefit obligation. We have recognized the full amount of our actuarially determined pension liability. The current portion recognized in our Consolidated Balance Sheets as other accrued expenses was $0.3 million as of January 31, 2017 and 2016. The long-term portion recognized in our Consolidated Balance Sheets as of January 31, 2017 and 2016 was $5.1 million and $5.2 million, respectively, as other non-current liabilities. Net periodic pension cost (benefit) of the supplemental retirement benefits for the fiscal years ended January 31, 2017, 2016 and 2015 was $0.2 million, ($0.4) million and $1.3 million, respectively.

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]
Equity-Based Compensation	(13) Equity-Based Compensation Layne has an equity-based compensation plan that provides for the granting of options to purchase or the issuance of shares of common stock at a price fixed by the Board of Directors or a committee. As of January 31, 2017, there were 348,949 shares which remain available to be granted under the plan as stock options or restricted stock awards. We have the ability to issue shares under the plans either from new issuances or from treasury, although we have previously always issued new shares and expect to continue to issue new shares in the future. We granted 13,495 shares of restricted stock, 199,352 restricted stock units and 447,903 performance vesting restricted stock units under the Layne Christensen Company 2006 Equity Incentive Plan during the fiscal year ended January 31, 2017. The grants consist of both service-based awards and market-based awards. We also granted a total of 134,333 stock options during the fiscal year ended January 31, 2017 under the Layne Christensen Company 2006 Equity Incentive Plan. All options were granted at an exercise price equal to the fair market value of our common stock at the date of grant. The options have terms of ten years from the date of grant and generally vest ratably over periods of one month to five years. We recognized $3.5 million, $3.9 million and $2.6 million of compensation cost for share-based plans for the fiscal years ended January 31, 2017, 2016 and 2015, respectively. Of these amounts, $3.0 million, $3.0 million and $1.2 million, respectively, related to non-vested stock. The total income tax benefit recognized for share-based compensation arrangements was $1.4 million, $1.5 million and $1.0 million for the fiscal years ended January 31, 2017, 2016 and 2015, respectively. As of January 31, 2017, no tax benefit is expected to be realized for equity-based compensation arrangements due to a full valuation allowance of our domestic deferred tax assets. As of January 31, 2017, total unrecognized compensation cost related to unvested stock options was approximately $0.2 million, which is expected to be recognized over a weighted-average period of 0.9 years. As of January 31, 2017, there was approximately $3.6 million of total unrecognized compensation cost related to nonvested restricted stock awards and restricted stock units that is expected to be recognized over a weighted-average period of 1.7 years. The fair value of share-based compensation granted in the form of stock options is determined using a lattice valuation model. The valuations in each respective year were made using the assumptions noted in the following table. Expected volatilities are based on historical volatility of the stock price. We use historical data to estimate early exercise and post-vesting forfeiture rates to be applied within the valuation model. The risk-free interest rate for the periods within the expected term of the option is based on the U.S. Treasury yield curve in effect at the time of grant. The weighted-average fair value per share at the date of grant for options granted during the fiscal years ended January 31, 2017, 2016 and 2015 was $1.59, $1.60 and $5.59, respectively. Years Ended January 31, Assumptions: 2017 2016 2015 Weighted-average expected volatility 56.1% 52.6% 51.0% Expected dividend yield 0% 0% 0% Risk-free interest rate 0.60% 0.70% 1.46% Expected term (in years) 1.9 3.3 5.6 Exercise multiple factor 1.39 1.65 1.9 Post-vesting forfeiture 20.3% 12.5% 13.1% Stock option transactions for the fiscal years ended January 31, 2017, 2016 and 2015 were as follows: Number of Shares Weighted Average Exercise Price Weighted Average Remaining Contractual Term (Years) Intrinsic Value (in thousands) Outstanding at February 1, 2014 1,105,812 $ 24.22 Granted 360,586 13.11 Exercised — — $ — Expired (55,126 ) 16.63 Forfeited (395,758 ) 23.03 Outstanding at January 31, 2015 1,015,514 21.15 Granted 106,168 5.51 Exercised — — — Expired (77,707 ) 24.73 Forfeited (204,260 ) 26.20 Outstanding at January 31, 2016 839,715 17.61 Granted 134,433 7.04 Exercised — — — Expired (10,000 ) 29.29 Forfeited (214,104 ) 21.19 Outstanding at January 31, 2017 750,044 14.54 6.5 1,107 Exercisable at January 31, 2015 653,978 24.46 Exercisable at January 31, 2016 576,871 19.00 Exercisable at January 31, 2017 611,453 15.43 6.2 1,037 Options expected to vest at January 31, 2017 138,591 10.61 7.9 70 The aggregate intrinsic value was calculated using the difference between the current market price and the exercise price for only those options that have an exercise price less than the current market price. Nonvested stock awards having service requirements only, are valued as of the grant date closing stock price and generally vest ratably over service periods of one to five years. Other nonvested stock awards vest based upon Layne meeting various performance goals. Certain nonvested stock awards provide for accelerated vesting if there is a change of control (as defined in the plans) or the disability or the death of the executive and for equitable adjustment in the event of changes in our equity structure. We granted certain performance based nonvested stock awards during the years ended January 31, 2017, 2016 and 2015, which were valued using the Monte Carlo simulation model. Assumptions used in the Monte Carlo simulation model for the fiscal years ended January 31, 2017, 2016 and 2015 were as follows: Years Ended January 31, Assumptions: 2017 2016 2015 Weighted-average fair value $ 4.70 $ 3.04 $ 8.96 Weighted-average expected volatility 58.3 % 44.2 % 37.0 % Expected dividend yield 0.0 % 0.0 % 0.0 % Weighted-average risk free rate 0.9 % 0.9 % 0.9 % Non-vested share transactions for the fiscal years ended January 31, 2017, 2016 and 2015 were as follows: Number of Shares Average Grant Date Fair Value Intrinsic Value (in thousands) Nonvested stock at February 1, 2014 292,423 $ 23.42 Granted - Directors 13,090 17.19 Granted - Restricted stock units 394,489 17.06 Granted - Performance vesting shares 244,679 8.96 Vested (13,027 ) 25.82 Forfeited (444,362 ) 18.95 Nonvested stock at January 31, 2015 487,292 14.86 Granted - Directors 24,085 5.19 Granted - Restricted stock units 130,287 5.25 Granted - Performance vesting shares 1,035,409 3.03 Vested (182,563 ) 17.07 Forfeited (87,340 ) 8.57 Nonvested stock at January 31, 2016 1,407,170 5.20 Granted - Directors 13,495 7.04 Granted - Restricted stock units 199,352 7.04 Granted - Performance vesting shares 447,903 4.70 Vested (26,349 ) 6.22 Forfeited (169,931 ) 8.29 Nonvested stock at January 31, 2017 1,871,640 5.00 $ 19,521

Fair Value Disclosures [Abstract]
Fair Value Measurements	(14) Fair Value Measurements Our estimates of fair value for financial assets and financial liabilities are based on the framework established in the fair value accounting guidance. The framework is based on the inputs used in the valuation, gives the highest priority to quoted prices in active markets and requires that observable inputs be used in the valuations when available. The three levels of the hierarchy are as follows: • Level 1 – Unadjusted quoted prices in active markets for identical assets or liabilities. • Level 2 – Observable inputs other than those included in Level 1, such as quoted market prices for similar assets and liabilities in active markets or quoted prices for identical assets in inactive markets. • Level 3 – Unobservable inputs reflecting our own assumptions and best estimate of what inputs market participants would use in pricing an asset or liability. Our assessment of the significance of a particular input to the fair value in its entirety requires judgment and considers factors specific to the asset or liability. Our financial instruments held at fair value, are presented below as of January 31, 2017 and 2016: Fair Value Measurements (in thousands) Carrying Value Level 1 Level 2 Level 3 January 31, 2017 Financial Assets: Long-term restricted deposits held at fair value $ 5,055 $ 5,055 $ — $ — Contingent consideration receivable (1) 4,244 — — 4,244 January 31, 2016 Financial Assets: Current restricted deposits held at fair value $ 3,466 $ 3,466 $ — $ — Long-term restricted deposits held at fair value 4,252 4,252 — — Contingent consideration receivable (1) 4,244 — — 4,244 (1) The contingent consideration receivable represents our share in the profits of one of the contracts assumed by the purchaser, as part of the sale of the Geoconstruction business on August 17, 2015. The amount was estimated based on the projected profits of the contract. There have been no changes in the estimated fair value since the closing date of the sale agreement. Other Financial Instruments We use the following methods and assumptions in estimating the fair value disclosures for our other financial instruments: Cash equivalents – The carrying amounts reported in the accompanying Consolidated Balance Sheets approximates their fair values and are classified as Level 1 within the fair value hierarchy. Short-term and long-term debt, other than the convertible notes – The fair value of debt instruments is classified as Level 2 within the fair value hierarchy and is valued using a market approach based on quoted prices for similar instruments traded in active markets. Where quoted prices are not available, the income approach is used to value these instruments based on the present value of future cash flows discounted at estimated borrowing rates for similar debt instruments or on estimated prices based on current yields for debt issues of similar quality and terms. Convertible notes – The convertible notes are measured on a non-recurring basis using Level 1 inputs based upon observable quoted prices of the 4.25% Convertible Notes and the 8.0% Convertible Notes. The following table summarizes the carrying values and estimated fair values of the long-term debt: January 31, 2017 January 31, 2016 Carrying Fair Carrying Fair (in thousands) Value Value Value Value 4.25% Convertible Notes $ 64,387 $ 64,705 $ 61,766 $ 49,873 8.0% Convertible Notes 97,952 92,156 97,205 92,156 During the fiscal year ended January 31, 2016, we performed an assessment of property and equipment located in Africa and Australia. Based on our assessment, we recorded a charge of approximately $3.9 million to adjust certain property and equipment with a carrying value of $10.4 million to its estimated fair value of $6.5 million. The fair value of the assets was determined primarily using Level 2 inputs that include available third-party quoted prices and appraisals of assets.

Contingencies

Commitments And Contingencies Disclosure [Abstract]
Contingencies	(15) Contingencies Our drilling activities involve certain operating hazards that can result in personal injury or loss of life, damage and destruction of property and equipment, damage to the surrounding areas, release of hazardous substances or wastes and other damage to the environment, interruption or suspension of drill site operations and loss of revenues and future business. The magnitude of these operating risks is amplified when, as is frequently the case, we conduct a project on a fixed-price, bundled basis where we delegate certain functions to subcontractors but remain responsible to the customer for the subcontracted work. In addition, we are exposed to potential liability under foreign, federal, state and local laws and regulations, contractual indemnification agreements or otherwise in connection with our services and products. Litigation arising from any such occurrences may result in Layne being named as a defendant in lawsuits asserting large claims. Although we maintain insurance protection which we consider economically prudent, there can be no assurance that any such insurance will be sufficient or effective under all circumstances or against all claims or hazards to which we may be subject or that we will be able to continue to obtain such insurance protection. A successful claim or damage resulting from a hazard for which we are not fully insured could have a material adverse effect on us. In addition, we do not maintain political risk insurance with respect to our foreign operations. Layne, through Geoconstruction, our discontinued segment, was a subcontractor on the foundation for an office building in California in 2013 and 2014. Geoconstruction's work on the project was completed in September 2014. Certain anomalies were subsequently discovered in the structural concrete, which were remediated by the general contractor during 2015. We have participated in discussions with the owner and the general contractor for the project regarding potential causes for the anomalies. During fiscal year ended January 31, 2016, the owner, the general contractor and Layne submitted a claim to the project’s insurers to cover the cost of remedial work, which claim was denied on November 2, 2016. The owner and the general contractor have filed a legal proceeding against the insurers seeking coverage under the insurance policy. Management does not believe that we are liable for any of the remediation costs related to this project. As of the date of this report, no action has been filed against us. Accordingly, no provision has been made in the Consolidated Financial Statements. As previously reported, beginning in October 2010, the Audit Committee of the Board of Directors conducted an internal investigation into, among other things, the legality of certain payments by Layne to agents and other third parties interacting with government officials in certain countries in Africa. The internal investigation suggested potential violations of the FCPA and certain local laws. Layne made a voluntary disclosure to the DOJ and the SEC regarding the results of the investigation and cooperated with the DOJ and SEC in connection with their review of the matter. The DOJ’s inquiry was closed in 2014. On October 27, 2014, Layne entered into a settlement with the SEC to resolve the allegations concerning potential violations of the FCPA. This settlement with the SEC resolves all outstanding government investigations with respect to Layne concerning potential FCPA violations. Under the terms of the settlement, without admitting or denying the SEC’s allegations, we consented to entry of an administrative cease-and-desist order under the books and records, internal controls and anti-bribery provisions of the FCPA. We agreed to pay to the SEC $4.7 million in disgorgement and prejudgment interest, and $0.4 million in penalties. The amounts in connection with the settlement were paid on November 6, 2014. We also agreed to undertake certain compliance, reporting and cooperation obligations to the SEC for two years following the settlement date. On November 9, 2016, we made our final report to the SEC and have no further reporting obligations to the SEC under the settlement. We are involved in various other matters of litigation, claims and disputes which have arisen in the ordinary course of business. We believe that the ultimate disposition of these matters will not, individually and in the aggregate, have a material adverse effect upon our business or consolidated financial position, results of operations or cash flows. However, it is possible, that future results of operations for any particular quarterly or annual period could be materially affected by changes in the assumptions related to these proceedings. In accordance with U.S. generally accepted accounting principles, we record a liability when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. These provisions are reviewed at least quarterly and adjusted to reflect the impacts of negotiations, settlements, rulings, advice of legal counsel, and other information and events pertaining to a particular case. To the extent additional information arises or the strategies change, it is possible that our estimate of the probable liability in these matters may change.

Discontinued Operations And Disposal Groups [Abstract]
Discontinued Operations	(16) Discontinued Operations Geoconstruction On August 17, 2015, we sold our Geoconstruction business segment to a subsidiary of Keller Foundations, LLC, a member of Keller Group plc (“Keller”), for a total of $42.3 million, including the preliminary estimate of the business segment’s working capital. After post-closing adjustments, the total purchase price increased to $47.7 million, to adjust for our estimated share in the profits of one of the contracts being assumed by Keller and final working capital adjustments. As of January 31, 2016, we had approximately $1.5 million held in an escrow account, which is part of Other Assets in the Consolidated Balance Sheet, which was paid in the fourth quarter of the fiscal year ended January 31, 2017 after the satisfaction of certain conditions. In addition, as of January 31, 2017 and 2016, we recognized a $4.2 million contingent consideration receivable, included in Other Assets in the Condensed Consolidated Balance Sheet. The contingent consideration represents our best estimate of our share in the profits of one of the contracts assumed by Keller. Tecniwell On October 31, 2014, we disposed of Tecniwell to Alberto Battini (50 %) and Paolo Trubini (50 %), an employee of Tecniwell at the time of disposal. The transaction was a sale by Layne of all quotas representing 100% of the corporate capital of Tecniwell in exchange for $0.9 million. The purchase price for the quotas was paid in two equal payments. Layne received $0.5 million on October 31, 2014 and the remainder on January 22, 2015. We recorded a loss on the sale of the business amounting to $0.8 million, which is included on the Consolidated Statements of Operations for the fiscal year ended January 31, 2015, as a loss from discontinued operations. Costa Fortuna On July 31, 2014, we disposed of Costa Fortuna to Aldo Corda, the original owner and the then current manager of the business at the time of the disposal. The transaction was structured as a sale by Layne of all of the issued and outstanding shares of Holub, S.A., a Uruguay Sociedad Anonima, Costa Fortuna’s parent company, and its subsidiaries in exchange for $4.4 million, payable to Layne as described below. The purchase price for the shares and remaining intercompany receivable is payable in future years, beginning with the year ended December 31, 2015, based on 33.33% of Costa Fortuna’s income before taxes for such year. The unpaid portion of the purchase price will accrue interest at the rate of 2.5% per annum. The unpaid balance of the purchase price, plus accrued interest, is due and payable to Layne on July 31, 2024. The loss on the sale of the business was $38.3 million, which is included in the Consolidated Statements of Operations for the fiscal year ended January 31, 2015 as a loss from discontinued operations. During the fiscal year ended January 31, 2016, we wrote off the balance of the receivable from the sale of Costa Fortuna amounting to $3.2 million, which is included under other income (expense) line in loss from discontinued operations in the Consolidated Statement of Operations. The financial results of the discontinued operations are as follows: Years Ended January 31, (in thousands) 2016 2015 Revenue $ 45,875 $ 109,588 Cost of revenues (exclusive of depreciation and amortization shown below) (34,120 ) (97,103 ) Selling, general and administrative expenses (exclusive of depreciation and amortization shown below) (10,004 ) (11,385 ) Depreciation and amortization (3,240 ) (9,864 ) Equity in earnings of affiliates 1,104 3,390 Other expense items (821 ) (1,822 ) Total operating loss on discontinued operations before income taxes (1,206 ) (7,196 ) Income tax expense (benefit) 1,460 (551 ) Total operating income (loss) on discontinued operations $ 254 $ (7,747 ) Total consideration $ 47,717 $ 3,538 Net book value of assets sold (31,776 ) (38,610 ) Reclassification adjustment for foreign currency translation — (3,794 ) Transaction costs associated with sale (3,036 ) (145 ) Gain (loss) on sale of discontinued operations before income taxes 12,905 (39,011 ) Income tax expense (5,102 ) (120 ) Total income (loss) on discontinued operations $ 8,057 $ (46,878 ) Prior to the completion of the sale of the Geoconstruction business segment, we owned 65% and 50% of Case-Bencor Joint Venture (Washington) and Case-Bencor Joint Venture (Iowa), respectively, which were both included as part of the Geoconstruction business segment as investments in affiliates, and were discontinued as a result of the sale.

Segment Reporting [Abstract]
Segments and Foreign Operations	(17) Segments and Foreign Operations We are a global solutions provider to the world of essential natural resources – water, minerals and energy. The Chief Operating Decision Maker (CODM) reviews operating results to determine the appropriate allocation of resources within the organization. The CODM defines the operational and organizational structure into discrete segments based on our primary product lines. In the first quarter of the fiscal year ended January 31, 2017, changes were made to simplify our business and streamline our operating and reporting structure. Our Collector Wells group was shifted from Heavy Civil to Water Resources to better align their operational expertise. We also shifted certain other smaller operations out of our “Other” segment and into our four reporting segments, and no longer report an “Other” segment. Information for prior periods has been recast to conform to our new presentation. During the third quarter of the fiscal year ended January 31, 2016, as a result of our strategic review of all aspects of our operations, we realigned our operating structure to combine the Energy Services segment with Water Resources segment. We determined that given the similar nature of the equipment and services for Energy Services and Water Resources, we can effectively manage our cost structure and serve our customer base in a combined segment. We now manage and report our operations through four segments: Water Resources, Inliner, Heavy Civil, and Mineral Services. Historical segment numbers have been recast to conform to this new operating structure. During the second quarter of the fiscal year ended January 31, 2016, we entered into a definitive agreement to sell our Geoconstruction business segment. The operating results of the Geoconstruction business are presented as discontinued operations and, as such, have been excluded from continuing operations and segment results for all periods presented. See Note 16 to Consolidated Financial Statements for further discussion. Layne’s segments are defined as follows: Water Resources Water Resources provides its customers with an array of water management solutions, including discovery and defining of water sources through hydrologic studies, water supply development through water well drilling and intake construction, and water delivery through pipeline and pumping infrastructure. Water Resources also brings technologies to the water and wastewater markets and offers water treatment equipment engineering services, providing systems for the treatment of regulated and nuisance contaminants, specifically, iron, manganese, hydrogen sulfide, arsenic, radium, nitrate, perchlorate, and volatile organic compounds. Water Resources drills deep injection wells for industrial and municipal clients that need to dispose of wastewater associated with their processes. Water Resources also performs complete diagnostic and rehabilitation services for existing wells, pumps and related equipment, including conducting downhole closed circuit televideo inspections to investigate and resolve water well and pump performance problems. In addition, Water Resources constructs radial collector wells through its Ranney® Collector Wells technology, which is an alternative to conventional vertical wells and can be utilized to develop moderate to very high capacities of groundwater. Water Resources provides water systems and services in most regions of the U.S. Inliner Inliner provides a wide range of process, sanitary and storm water rehabilitation solutions to municipalities and industrial customers dealing with aging infrastructure needs. Inliner focuses on its proprietary Inliner ® cured-in-place pipe (“CIPP”) which allows it to rehabilitate aging sanitary sewer, storm water and process water infrastructure to provide structural rebuilding as well as infiltration and inflow reduction. Inliner’s trenchless technology minimizes environmental impact and reduces or eliminates surface and social disruption. Inliner has the ability to supply both traditional felt-based CIPP lining tubes cured with water or steam as well as a fiberglass-based lining tubes cured with ultraviolet light. Inliner owns the North American rights to the Inliner CIPP technology, owns and operates the liner manufacturer, and also provides installation of Inliner CIPP product. While Inliner focuses on our proprietary Inliner CIPP, it provides full system renewal, including a wide variety of other rehabilitative methods including Janssen structural renewal for service lateral connections and mainlines, slip lining, traditional excavation and replacement, and form and manhole renewal with cementitious and epoxy products. Inliner provides services in most regions of the U.S. Heavy Civil Heavy Civil performs design and build services of water and wastewater treatment plants, as well as pipeline installation, to government agencies and industrial clients. In addition, Heavy Civil builds surface water intakes, pumping stations, hard rock tunnels and marine construction services-all in support of the water infrastructure in the U.S. Beyond water solutions, Heavy Civil also designs and constructs biogas facilities for the purpose of generating and capturing methane gas, an emerging renewable energy resource. Heavy Civil provides services in most regions of the U.S. As disclosed in Note 21 to the Consolidated Financial Statements, on February 8, 2017, we entered into an Asset Purchase Agreement to sell substantially all of the assets of our Heavy Civil business. Mineral Services Mineral Services conducts primarily above ground drilling activities, including all phases of core drilling, reverse circulation, dual tube, hammer and rotary air-blast methods. Our service offerings include both exploratory and definitional drilling. Global mining companies engage companies such as Mineral Services to extract samples from sites that the mining companies analyze for mineral content before investing heavily in development to extract the minerals. Mineral Services helps its clients determine if minable mineral deposit is on the site, the economic viability of the mining site and the geological properties of the ground, which helps in the determination of mine planning. Mineral Services also offers its customers water management and soil stabilization expertise. Mine water management consists of vertical, large diameter wells for sourcing and dewatering; and horizontal drains for slope de-pressurization. The primary markets are in the western U.S., Mexico, and South America. As discussed in Note 18 to the Consolidated Financial Statements, during the fiscal year ended January 31, 2016, we implemented a plan to exit our operations in Africa and Australia. Mineral Services also has ownership interests in foreign affiliates operating in Latin America that form our primary presence in Chile and Peru. Financial information for our segments is presented below. Unallocated corporate expenses primarily consist of general and administrative functions performed on a company-wide basis and benefiting all segments. These costs include accounting, financial reporting, internal audit, treasury, legal, tax compliance, executive management and board of directors. Corporate assets consist of assets not directly associated with a segment, and consist primarily of cash and deferred income taxes. Management evaluates segment performance based primarily on revenues and Adjusted EBITDA. Adjusted EBITDA represents income or loss from continuing operations before interest, taxes, depreciation and amortization, non-cash equity-based compensation, equity in earnings or losses from affiliates, certain non-recurring items such as impairment charges, restructuring costs, gain on extinguishment of debt, and certain other gains or losses, plus dividends received from affiliates.

Restructuring And Related Activities [Abstract]
Restructuring Costs	(18) Restructuring Costs During the second quarter of the fiscal year ended January 31, 2017, we initiated a plan to reduce costs and improve our profitability in our Water Resources segment (“Water Resources Business Performance Initiative”). The Water Resources Business Performance Initiative involves cost rationalization, increased standardization of functions such as sales, pricing and estimation, disposal of underutilized assets, and process improvements to drive efficiencies. We recorded approximately $3.2 million in restructuring costs related to the Water Resources Business Performance Initiative for the fiscal year ended January 31, 2017, which includes costs related to office closures and severance costs. We estimate remaining amounts to be incurred for the Water Resources Business Performance Initiative of approximately $0.1 million. During the fiscal year ended January 31, 2017, we continued the implementation of our FY2016 Restructuring Plan, which involves the exit of our operations in Africa and Australia and other actions to support our strategic focus in simplifying the business and build upon our capabilities in water (“FY2016 Restructuring Plan”). For the fiscal year ended January 31, 2017, we recognized approximately $14.1 million of restructuring expenses for the FY2016 Restructuring Plan, primarily related to the closure of our Australian and African entities resulting in the impairment of our assets held for sale. In calculating the impairment, the carrying amount of the assets included the cumulative currency translation adjustment related to our Australian and African entities. Also included are severance costs and other personnel-related costs, and other costs to support our business focus and strategy. For the fiscal year ended January 31, 2017, the FY2016 Restructuring Plan related to the segments as follows: $13.3 million in Mineral Services, $0.4 million in Heavy Civil, $0.3 million in Corporate, and $0.1 million in Inliner. The FY2016 Restructuring Plan was substantially completed as of January 31, 2017. We estimate remaining amounts to be incurred for the FY2016 Restructuring Plan of approximately $0.1 million. We previously implemented a restructuring plan during the second quarter of the fiscal year ended January 31, 2015 (“FY2015 Restructuring Plan”). The FY2015 Restructuring Plan involved, among other things, reductions in the global workforce, asset relocation or disposal and process improvements. The FY2015 Restructuring Plan was designed to achieve short and long-term cost reductions, and was completed during the first quarter of the fiscal year ended January 31, 2016. The following table summarizes the carrying amount of the accrual for the restructuring plans discussed above: Severance and other personnel- Write-down related of Asset (in thousands) costs inventory write-down Other Total FY2015 Restructuring Plan $ 1,440 $ — $ — $ 1,258 $ 2,698 Cash expenditures (935 ) — — (776 ) (1,711 ) Balance at January 31, 2015 $ 505 $ — $ — $ 482 $ 987 Restructuring Costs FY2016 Restructuring Plan $ 3,657 $ — $ 3,870 $ 835 $ 8,362 FY2015 Restructuring Plan 13 — — 1,579 1,592 Total Restructuring Costs $ 3,670 $ — $ 3,870 $ 2,414 $ 9,954 Write-down of inventory — 7,905 — — 7,905 Cash expenditures (3,105 ) — — (1,218 ) (4,323 ) Non-cash expense — (7,905 ) (3,870 ) (1,245 ) (13,020 ) Adjustment to liability 87 — — (377 ) (290 ) Balance at January 31, 2016 $ 1,157 $ — $ — $ 56 $ 1,213 Restructuring Costs Water Resources Business Performance Initiative $ 459 $ — $ — $ 2,745 $ 3,204 FY2016 Restructuring Plan 397 — 12,878 869 14,144 Total Restructuring Costs $ 856 $ — $ 12,878 $ 3,614 $ 17,348 Cash expenditures (1,354 ) — — (3,532 ) (4,886 ) Non-cash expense (1) — — (12,878 ) — (12,878 ) Adjustment to liability 10 — — 32 42 Balance at January 31, 2017 $ 669 $ — $ — $ 170 $ 839 (1) For the fiscal year ended January 31, 2017, we recognized an impairment of assets held for sale in Australia and Africa.

Accounting Changes And Error Corrections [Abstract]
New Accounting Pronouncements	(19) New Accounting Pronouncements On January 26, 2017, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2017-04, “Intangibles—Goodwill and Other: Simplifying the Test for Goodwill Impairment,” which simplifies the manner in which an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. However, under the amendments in this ASU, an entity should (1) perform its annual or interim goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount, and (2) recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value, with the understanding that the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. The guidance is effective for us beginning on February 1, 2020 and will be applied on a prospective basis. We are currently evaluating the effect that the adoption of this ASU will have on our financial statements. On December 22, 2016, the FASB issued ASU 2016-20, “Technical Corrections and Improvements to Revenue from Contracts with Customers.” The amendments in ASU 2016-20 include thirteen technical corrections and improvements that affect only narrow aspects of the guidance issued in ASU 2014-09. These narrow aspects include (1) pre-production costs related to long-term supply arrangements; (2) contract costs–impairment testing; (3) contract costs–interaction of impairment testing with guidance in other Topics; (4) provisions for losses on production-type and construction-type contracts; (5) scope of FASB ASC 606; (6) disclosure of remaining performance obligations; (7) contract modifications example; (8) fixed-odds wagering contracts in the casino industry; (9) cost capitalization for advisors to private and public funds, (10) loan guarantee fees; (11) contract asset versus receivable; (12) refund liability; and (13) advertising costs. ASU 2016-20 will become effective when the guidance in ASU No. 2014-09 becomes effective, beginning February 1, 2018 for Layne. We are currently evaluating the effect that the adoption of this ASU will have on our financial statements. In November 2016, the FASB issued ASU 2016-18, “Statement of Cash Flows: Restricted Cash,” which provides guidance about the presentation of changes in restricted cash and restricted cash equivalents on the statement of cash flows. This ASU is effective for us beginning on February 1, 2018 and will be applied using a retrospective transition method to each period presented. We are currently evaluating the effect that the adoption of this ASU will have on our financial statements. In August 2016, the FASB issued ASU 2016-15, “Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments.” This ASU provides guidance and clarification in regards to the classification of eight types of receipts and payments in the statement of cash flows, including debt repayment or extinguishment costs, settlement of zero-coupon bonds, proceeds from the settlement of insurance claims, distributions received from equity method investees and cash receipts from beneficial interest in securitization transactions. The guidance is effective for us beginning on February 1, 2018 and will be applied using a retrospective transition method to each period presented. We are currently evaluating the effect that the adoption of this ASU will have on our financial statements. In February 2016, the FASB issued ASU 2016-02, “Leases,” which establishes a right-of-use (ROU) model that requires a lessee to record an ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. This ASU is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. ASU 2016-02 requires modified retrospective adoption for all leases existing at, or entered into after, the date of initial application, with an option to use certain transition relief. We anticipate adopting this ASU beginning on February 1, 2019. We are currently evaluating the effect that the adoption of this ASU will have on our financial statements. See Note 11 to the Consolidated Financial Statements for further discussion of our operating leases. On July 22, 2015, the FASB issued ASU On August 27, 2014, FASB issued ASU 2014-15, “Disclosure of Uncertainties About an Entity’s Ability to Continue as a Going Concern”. The guidance, which is effective for annual reporting periods ending after December 15, 2016, extends the responsibility for performing the going-concern assessment to management and contains guidance on how to perform a going-concern assessment and when going-concern disclosures would be required under GAAP. We adopted this guidance on the fourth quarter of the fiscal year ended January 31, 2017 and it did not have a material effect on our financial statements. The FASB issued ASU 2014-09, “Revenue from Contracts with Customers” on May 28, 2014. On August 12, 2015, the FASB issued ASU 2015-14, which defers the adoption of ASU 2014-09 to annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Earlier application is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. This guidance defines the steps to recognize revenue for entities that have contracts with customers as well as requiring significantly expanded disclosures regarding the qualitative and quantitative information of the nature, amount, timing, and uncertainty of revenue and cash flows arising from such contracts. We have completed our initial assessment of this ASU and anticipate adopting the new guidance beginning on February 1, 2018 using the full retrospective method that will result in restatement of the comparative periods presented. We are in the process of preparing to implement changes to our accounting policies and controls, business processes and information systems to support the new revenue recognition and disclosure requirements. We are continuing to evaluate the potential impact that this ASU will have on our financial position and results of operations.

As a result, it is not practical to allocate a portion of depreciation and amortization to cost of revenues for the presentation of gross profit. (2) Loss per share was computed independently for each of the quarters presented. The sum of the quarters may not equal the total year amount due to the impact of changes in average quarterly shares outstanding. We incurred restructuring costs as part of our Water Resources Business Performance Initiative and our FY2016 Restructuring Plan, consisting primarily of costs related to office closures, severance costs, impairment of our assets held for sale related to the closure of our Australian and African entities, and other costs to support our business focus and strategy. The total impact of these restructuring costs was $0.5 million, $1.0 million, $1.7 million and $14.2 million during the first quarter, second quarter, third quarter and fourth quarter of the fiscal year ended January 31, 2017, respectively. 2016 (in thousands, except per share data) First Second Third Fourth Revenues $ 174,271 $ 176,317 $ 173,179 $ 159,243 Cost of revenues (exclusive of depreciation, amortization and impairment charges shown below) (1) (143,231 ) (151,249 ) (142,941 ) (132,657 ) Depreciation and amortization (8,735 ) (8,254 ) (7,940 ) (7,756 ) Impairment charges — (4,598 ) — — Net loss from continuing operations (6,574 ) (23,510 ) (8,994 ) (13,784 ) Net loss (6,558 ) (18,154 ) (3,442 ) (16,651 ) Net (loss) income attributable to noncontrolling interests — — — 28 Net loss attributable to Layne Christensen Company (6,558 ) (18,154 ) (3,442 ) (16,623 ) Loss per share from continuing operations - basic and diluted (2) (0.34 ) (1.19 ) (0.45 ) (0.70 ) Loss per share - basic and diluted (2) (0.33 ) (0.93 ) (0.17 ) (0.84 ) (1) As discussed in Note 1 to the Consolidated Financial Statements, we utilize multiple methods of revenue recognition based on the nature of work performed.

The sum of the quarters may not equal the total year amount due to the impact of changes in average quarterly shares outstanding. The second quarter of the fiscal year ended January 31, 2016 was impacted by a $4.6 million impairment charge for the Energy Services segment, which was previously reported as a separate segment prior to the segment being combined with Water Resources segment effective the third quarter of the fiscal year ended January 31, 2016. As discussed in Note 4 to the Consolidated Financial Statements, the impairment charge was recorded to reflect reductions in the estimated fair value of certain long-lived assets. As part of our exit of operations in Africa and Australia, we incurred restructuring costs consisting primarily of severance costs and other personnel-related costs, as well as a write-down of the carrying value of inventory and fixed assets. The total impact of these restructuring costs was $10.6 million, $2.1 million and $2.9 million during the second quarter, third quarter and fourth quarter of the fiscal year ended January 31, 2016, respectively.

Subsequent Events [Abstract]
Subsequent Events	( 21) Subsequent Event On February 8, 2017, we entered into an Asset Purchase Agreement to sell substantially all of the assets of our Heavy Civil business for $10.1 million, subject to certain working capital adjustments. The purchaser of the Heavy Civil business is Reycon Partners LLC (the "Buyer"), which is owned by a group of private investors, including members of the current Heavy Civil senior management team. The Buyer has the option to pay up to $3.7 million of the consideration in the form of Layne common stock currently owned by the owners of the Buyer (valued at the weighted average price of Layne's common stock for the 10 trading days immediately prior to the closing date). The total purchase price for the assets will increase or decrease on a dollar-for-dollar basis to the extent the Heavy Civil division's working capital is more or less than an agreed upon target working capital amount. In addition, Layne and the Buyer have agreed to split equally any amounts received with respect to a $3.5 million outstanding receivable related to a job contract that is substantially completed. Subject to satisfaction of closing conditions, including obtaining any required consents and approvals, the transaction is expected to close within 90 days from the date of the Asset Purchase Agreement. We expect to recognize a loss on the sale of our Heavy Civil business during the first half of fiscal year ended January 31, 2018.

Summary of Significant Accoun31

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Jan. 31, 2017
Accounting Policies [Abstract]
Description of Business	Description of Business – Layne Christensen Company and subsidiaries (together, “Layne,” the “Company,” “we,” “our,” or “us”) is a global water management, construction and drilling company. We primarily operate in North America and South America. Our customers include government agencies, investor-owned utilities, industrial companies, global mining companies, consulting engineering firms, heavy civil construction contractors, oil and gas companies, power companies and agribusinesses. We have ownership interests in certain foreign affiliates operating in Latin America (see Note 5 to the Consolidated Financial Statements).
Fiscal Year	Fiscal Year – Layne’s fiscal year end is January 31. References to fiscal years, or “FY,” are to the twelve months then ended.
Investment in Affiliated Companies	Investment in Affiliated Companies – Investments in affiliates ( 20% to 50% owned) in which we have the ability to exercise significant influence, but do not hold a controlling interest over operating and financial policies, are accounted for by the equity method. We evaluate our equity method investments for impairment at least annually or when events or changes in circumstances indicate there is a loss in value of the investment that is other than a temporary decline. During the fiscal year ended January 31, 2017, due to the extended downturn in the minerals market due to lower commodity prices for the past few years, we reviewed our equity method investments for impairment. Based on weighted approach of the discounted cash flow method and market approach, we concluded that the fair value exceeds the carrying amount of our equity investments. Accordingly, no impairment charge was recorded during the fiscal year ended January 31, 2017.
Principles of Consolidation	Principles of Consolidation – The Consolidated Financial Statements include the accounts of Layne and all of our subsidiaries where we exercise control. For investments in subsidiaries that are not wholly-owned, but where we exercise control, the equity held by the minority owners and their portions of net income (loss) are reflected as noncontrolling interests. All intercompany accounts and transactions have been eliminated in consolidation. In the Notes to Consolidated Financial Statements, all dollar and share amounts in tabulations are in thousands of dollars and shares, respectively, unless otherwise indicated.
Presentation	Presentation – Beginning with the first quarter of fiscal year ended January 31, 2017, we are excluding nonvested restricted stock units (“RSU”) from the total shares issued and outstanding in our Consolidated Balance Sheets, since no shares are actually issued until the shares have vested and are no longer restricted. Once the restriction lapses on RSUs, the units are converted to unrestricted shares of our common stock and the par value of the stock is reclassified from additional paid-in-capital to common stock. RSU shares in prior periods have been reclassified to conform to this presentation. As discussed further in Note 16 to the Consolidated Financial Statements, during the third quarter of fiscal year ended January 31, 2016, we completed the sale of our Geoconstruction business segment. During the fiscal year ended January 31, 2015, we sold Costa Fortuna and Tecniwell, both previously reported in the Geoconstruction operating segment. The results of operations related to the Geoconstruction business segment have been classified as discontinued operations for all periods presented through the date of sale. Unless noted otherwise, discussion in these Notes to Consolidated Financial Statements pertains to continuing operations. Amounts presented on the Consolidated Balance Sheets have also been reclassified.
Business Segments	Business Segments – We report our financial results under four reporting segments consisting of Water Resources, Inliner, Heavy Civil and Mineral Services. During the first quarter of fiscal year ended January 31, 2017, changes were made to simplify our business and streamline our operating and reporting structure. Our Collector Wells group was shifted from Heavy Civil to Water Resources to better align their operational expertise. We also shifted certain other smaller operations out of our “Other” segment and into our four reporting segments, and no longer report an “Other” segment. Information for prior periods has been recast to conform to our new presentation. We also report corporate activities under the title “Unallocated Corporate.” Unallocated corporate expenses primarily consist of general and administrative functions performed on a company-wide basis and benefiting all segments. These costs include accounting, financial reporting, internal audit, treasury, legal, tax compliance, executive management and board of directors. Corporate assets are all assets not directly associated with a segment, and consist primarily of cash and deferred income taxes.
Use of and Changes in Estimates	Use of and Changes in Estimates – The preparation of financial statements in conformity with accounting principles generally accepted in the U.S. requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Estimates and assumptions about future events and their effects cannot be perceived with certainty, and accordingly, these estimates may change as new events occur, as more experience is acquired, as additional information is obtained and as Layne’s operating environment changes. While we believe that the estimates and assumptions used in the preparation of the Consolidated Financial Statements are appropriate, actual results could differ from those estimates.
Foreign Currency Transactions and Translation	Foreign Currency Transactions and Translation – In accordance with ASC Topic 830, “Foreign Currency Matters,” gains and losses resulting from foreign currency transactions are included in the Consolidated Statements of Operations. Assets and liabilities of non-U.S. subsidiaries whose functional currency is the local currency are translated into U.S. dollars at exchange rates prevailing at the balance sheet date. The net foreign currency exchange differences resulting from these translations are reported in accumulated other comprehensive loss. Revenues and expenses are translated at average foreign currency exchange rates during the year. The cash flows and financing activities of our operations in Mexico are primarily denominated in U.S. dollars. Accordingly, these operations use the U.S. dollar as their functional currency. Monetary assets and liabilities are remeasured at period end foreign currency exchange rates and nonmonetary items are measured at historical foreign currency exchange rates with exchange rate differences reported in the Consolidated Statement of Operations. Net foreign currency transaction losses were $0.2 million, $0.1 million, and $0.2 million for the fiscal years ended January 31, 2017, 2016 and 2015, respectively, and are recorded in other income, net in the accompanying Consolidated Statements of Operations.
Revenue Recognition	Revenue Recognition – Revenues are recognized on large, long-term construction contracts meeting the criteria of ASC Topic 605-35 “Construction-Type and Production-Type Contracts” (“ASC Topic 605-35”), using the percentage-of-completion method based upon the ratio of costs incurred to total estimated costs at completion. Contract price and cost estimates are reviewed periodically as work progresses and adjustments proportionate to the percentage of completion are reflected in contract revenues in the reporting period when such estimates are revised. The nature of accounting for contracts is such that refinements of the estimating process for changing conditions and new developments are continuous and characteristic of the process. Many factors can and do change during a contract performance period which can result in a change to contract profitability including differing site conditions (to the extent that contract remedies are unavailable), the availability of skilled contract labor, the performance of major material suppliers, the performance of major subcontractors, unusual weather conditions and unexpected changes in material costs. These factors may result in revision to costs and income and are recognized in the period in which the revisions become known. Provisions for estimated losses on uncompleted construction contracts are made in the period in which such losses become known. When the estimate on a contract indicates a loss, the entire loss is recorded during the accounting period in which the facts that caused the revision become known. Management evaluates the performance of contracts on an individual basis. In the ordinary course of business, but at least quarterly, we prepare updated estimates of cost and profit or loss for each contract. The cumulative effect of revisions in estimates of the total forecasted revenue and costs, including unapproved change orders and claims, during the course of the contract is reflected in the accounting period in which the facts that caused the revision become known. Large changes in cost estimates on larger, more complex construction projects can have a material impact on our financial statements and are reflected in results of operations when they become known. During the fiscal years ended January 31, 2017, 2016 and 2015, approximately $12.9 million, $22.2 million and $25.2 million in losses on open contracts were recorded, respectively. We record revenue on contracts relating to unapproved change orders and claims by including in revenue an amount less than or equal to the amount of the costs incurred by us to date for contract price adjustments that we seek to collect from customers for delays, errors in specifications or designs, change orders in dispute or unapproved as to scope or price, or other unanticipated additional costs, in each case when recovery of the costs is considered probable. The amount of unapproved change orders and claims revenues are included in our Consolidated Balance Sheets as part of costs and estimated earnings in excess of billings on uncompleted contracts. See Note 2 to the Consolidated Financial Statements. When determining the likelihood of eventual recovery, we consider such factors as our experience on similar projects and our experience with the customer. As new facts become known, an adjustment to the estimated recovery is made and reflected in the current period. As allowed by ASC Topic 605-35, revenue is recognized on smaller, short-term construction contracts using the completed contract method. Provisions for estimated losses on uncompleted construction contracts are made in the period in which such losses become known. We determine when contracts such as these are completed based on acceptance by the customer. Revenues for drilling contracts within Mineral Services are recognized in terms of the value of total work performed to date on the basis of actual footage or meterage drilled. Revenues for direct sales of equipment and other ancillary products not provided in conjunction with the performance of construction contracts are recognized at the date of delivery to, and acceptance by, the customer. Provisions for estimated warranty obligations are made in the period in which the sales occur. Our revenues are presented net of taxes imposed on revenue-producing transactions with our customers, such as, but not limited to, sales, use, value-added and some excise taxes.
Inventories	Inventories – We value inventories at the lower of cost or market. Cost of U.S. inventories and the majority of foreign operations are determined using the average cost method, which approximates FIFO. Inventories consist primarily of supplies and raw materials. Supplies of $ 18.8 million and $16.8 million and raw materials of $2.3 million and $2.7 million were included in inventories, net of reserves of $0.9 million and $1.2 million, in the Consolidated Balance Sheets as of January 31, 2017 and 2016, respectively.
Property and Equipment	Property and Equipment – Property and equipment (including major renewals and improvements) are recorded at cost less accumulated depreciation. Depreciation is provided using the straight-line method. The useful lives used for the items within each property classification are as follows: Classification Years Buildings 15 - 35 Machinery and equipment 3 - 10 Property and equipment are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Recoverability is evaluated by comparing the carrying value of the assets to the undiscounted associated cash flows. When this comparison indicates that the carrying value of the asset is greater than the undiscounted cash flows, a loss is recognized for the difference between the carrying value and estimated fair value. Fair value is determined based either on market quotes or appropriate valuation techniques. See Note 4 to the Consolidated Financial Statements for a discussion of fixed asset impairments recognized during the fiscal year ended January 31, 2016. As discussed in Note 18 to the Consolidated Financial Statements, during the fiscal year ended January 31, 2016, we implemented a plan to exit our operations in Africa and Australia. As a result of the decision, we determined that it was more likely than not that certain fixed assets will be sold or otherwise disposed of before the end of their estimated useful lives. We recorded charges of approximately $12.9 million and $3.9 million during the fiscal years ended January 31, 2017 and 2016, respectively, to adjust the carrying values of property and equipment in Africa and Australia to estimated fair values, based upon valuation information that includes available third-party quoted prices and appraisals of assets. In calculating the impairment for fiscal year ended January 31, 2017, the carrying amount of the assets included the cumulative currency translation adjustment related to our African and Australian entities. The charges are shown as part of restructuring costs in the Consolidated Statement of Operations. We reflect property as assets held for sale when management, having the authority to approve the action, commits to a plan to sell the asset, the sale is probable within one year, and the asset is available for immediate sale in its present condition. We also consider whether an active program to locate a buyer has been initiated, whether the asset is marketed actively for sale at a price that is reasonable in relation to its current fair value, and whether actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn. Upon designation as asset held for sale, we record the carrying value of each asset at the lower of its carrying value or its estimated fair value, less estimated costs to sell, and cease recording depreciation. During the fourth quarter of the fiscal year ended January 31, 2017, we determined that our assets in Australia amounting to $2.5 million, which is part of Mineral Services segment, met all of the held for sale criteria, and as such were classified as held for sale in the Consolidated Balance Sheet as of January 31, 2017. We recorded a reserve for assets held for sale related to Australia of $12.4 million as of January 31, 2017, and the reserve is included as part of Other Current Liabilities in the Consolidated Balance Sheet. During the fourth quarter of the fiscal year ended January 31, 2016, we determined that assets in our Ethiopian location amounting to $0.8 million, which is part of Mineral Services segment, met all of the held for sale criteria, and as such were classified as held for sale in the Consolidated Balance Sheet as of January 31, 2017 and 2016. During the fourth quarter of the fiscal year ended January 31, 2015, assets in our Redlands, California location amounting to $1.4 million, which is part of the Water Resources segment, were classified as held for sale. Due to unforeseen circumstances, the foregoing sale was not completed during the past two fiscal years; however, the assets continue to meet the held for sale criteria as of January 31, 2017, and disposition is expected to be completed within the next twelve months.
Discontinued Operations	Discontinued Operations – We adopted Accounting Standards Update 2014-08, "Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity," on February 1, 2015. Under the new guidance, a discontinued operation is defined as a disposal of a component or group of components that is disposed of or is classified as held for sale and represents a strategic shift that has or will have a major effect on an entity’s operations and financial results. See Note 16 to the Consolidated Financial Statements for a discussion of our discontinued operations.
Goodwill	Goodwill –In accordance with ASC Topic 350-20, “Intangibles-Goodwill and Other”, we are required to test for the impairment of goodwill on at least an annual basis. We conduct this evaluation annually as of December 31 or more frequently if events or changes in circumstances indicate that goodwill might be impaired. Our reporting units are based on our organizational and reporting structure and are the same as our four reportable segments. Corporate and other assets and liabilities are allocated to the reporting units to the extent that they relate to the operations of those reporting units in determining their carrying amount. We have the option of first performing a qualitative assessment to determine the existence of events and circumstances that would lead to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If such a conclusion is reached, then we would be required to perform a quantitative impairment assessment of goodwill. However, if the assessment leads to a determination that it is more likely than not that the fair value of a reporting unit is greater than its carrying amount, no further assessments are required. As of December 31, 2016 and 2015, we performed a qualitative assessment for our annual goodwill impairment test, and determined that it was more likely than not that the fair value of Inliner, the only reporting unit with goodwill, would exceed its carrying value . As of January 31, 2017 and 2016, we had $8.9 million of goodwill on the Consolidated Balance Sheets. The goodwill is all attributable to the Inliner reporting segment. Goodwill expected to be tax deductible was $0.9 million as of January 31, 2017 and 2016. The cumulative goodwill impairment losses for Water Resources, Inliner, Heavy Civil and Mineral Services were $17.5 million, $23.1 million, $44.6 million and $20.2 million, respectively, which were recorded during the fiscal year ended January 31, 2012.
Intangible Assets	Intangible Assets – Other intangible assets with finite lives primarily consist of tradenames and patents. Intangible assets are being amortized using the straight-line method over their estimated useful lives, which range from ten to thirty-five years. Finite-lived intangible assets are reviewed for recoverability whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable.
Cash and Cash Equivalents	Cash and Cash Equivalents – We consider investments with an original maturity of three months or less when purchased to be cash equivalents. Our cash equivalents are subject to potential credit risk. Our cash management and investment policies restrict investments to investment grade, highly liquid securities. The carrying value of cash and cash equivalents approximates fair value.
Restricted Deposits	Restricted Deposits – Restricted deposits consist of escrow funds related to a certain disposition, and judicial deposits associated with tax related legal proceedings in Brazil. Restricted deposits – current of $ 3.5 million as of January 31, 2016, are included in Other Current Assets in the Consolidated Balance Sheet. Restricted deposits – non-current of $5.0 million and $4.3 million as of January 31, 2017 and 2016, respectively, are included in Other Assets in the Consolidated Balance Sheets.
Allowance for Uncollectible Accounts Receivable	Allowance for Uncollectible Accounts Receivable – We make ongoing estimates relating to the collectability of our accounts receivable and maintain an allowance for estimated losses resulting from the inability of our customers to make required payments. In determining the amount of the allowance, we make judgments about the creditworthiness of customers based on ongoing credit evaluations, and also consider a review of accounts receivable aging, industry trends, customer financial strength, credit standing and payment history to assess the probability of collection. Bad debt expense, which is recorded as part of Selling, General and Administrative Expenses in the Consolidated Statement of Operations, amounted to $ 1.9 million, ($0.6) million, and $0.8 million for the fiscal years ended January 31, 2017, 2016 and 2015, respectively. We do not establish an allowance for credit losses on long-term contract unbilled receivables. Adjustments to unbilled receivables related to credit quality, if they occur, are accounted for as a reduction of revenue.
Concentration of Credit Risk	Concentration of Credit Risk – We grant credit to our customers, which may include concentrations in state and local governments. Although this concentration could affect our overall exposure to credit risk, we believe that our portfolio of accounts receivable is sufficiently diversified, thus spreading the credit risk. To manage this risk, we perform periodic credit evaluations of our customers’ financial condition, including monitoring our customers’ payment history and current credit worthiness. We do not generally require collateral in support of our trade receivables, but may require payment in advance or security in the form of a letter of credit or bank guarantee. During the fiscal years ended January 31, 2017, 2016 and 2015, no individual customer accounted for more than 10% of our consolidated revenues.
Accrued Insurance	Accrued Insurance – We maintain insurance programs where we are responsible for the amount of each claim up to a self-insured limit. Estimates are recorded for health and welfare, workers’ compensation, property and casualty insurance costs that are associated with these programs. These costs are estimated based in part on actuarially determined projections of future payments under these programs and include amounts incurred but not reported. Should a greater amount of claims occur compared to what was estimated or costs of the medical profession increase beyond what was anticipated, accruals recorded may not be sufficient and additional costs to the consolidated financial statements could be required. Costs estimated to be incurred in the future for employee health and welfare benefits, workers’ compensation, property and casualty insurance programs resulting from claims which have been incurred are accrued currently. Under the terms of the agreement with the various insurance carriers administering these claims, we are not required to remit the total premium until the claims are actually paid by the insurance companies.
Fair Value of Financial Instruments	Fair Value of Financial Instruments – The carrying amounts of financial instruments, including cash and cash equivalents, customer receivables and accounts payable, approximated fair value at January 31, 2017 and 2016, because of the relatively short maturity of those instruments. See Note 14 to the Consolidated Financial Statements for fair value disclosures.
Litigation and Other Contingencies	Litigation and Other Contingencies – We are involved in litigation incidental to our business, the disposition of which is not expected to have a material effect on our business, financial position, results of operations or cash flows. In addition, some of our contracts contain provisions that require payment of liquidated damages if we are responsible for the failure to meet specified contractual milestone dates and the applicable customer asserts a claim under these provisions. These contracts define the conditions under which our customers may make claims against Layne for liquidated damages. In many cases in which we have historically had potential exposure for liquidated damages, such damages ultimately were not asserted by our customers. It is possible, however, that future results of operations for any particular quarterly or annual period could be materially affected by changes in our assumptions related to these proceedings. If the assessment of a contingency indicates that it is probable that a material loss has been incurred and the amount of the liability can be estimated, then the estimated liability is accrued in our Consolidated Financial Statements. If the assessment indicates that a potentially material loss contingency is not probable but is reasonably possible, or is probable but cannot be estimated, then the nature of the contingent liability, and an estimate of the range of possible losses, if determinable and material, is disclosed. These provisions are reviewed at least quarterly and adjusted to reflect the impacts of negotiations, settlements, rulings, advice of legal counsel, and other information and events pertaining to a particular case.
Supplemental Cash Flow Information	Supplemental Cash Flow Information –The amounts paid or refunded for income taxes, interest and non-cash investing and financing activities were as follows: Years Ended January 31, (in thousands) 2017 2016 2015 Income taxes paid $ 1,555 $ 1,947 $ 3,882 Income tax refunds (596 ) (4,251 ) (394 ) Interest paid 12,331 11,065 6,737 Noncash investing and financing activities: Exchange of 4.25% Convertible Notes for 8.0% Convertible Notes — 55,500 — Contingent consideration on sale of discontinued operations — 4,244 — Receivable on sale of discontinued operations — — 2,638 Accrued capital additions 1,427 1,186 774
Income Taxes	Income Taxes – Income taxes are provided using the asset and liability method, in which deferred taxes are recognized on the difference between the financial statement carrying amounts and tax bases of existing assets and liabilities. Deferred tax assets are reviewed for recoverability and valuation allowances are provided as necessary. Provision for U.S. income taxes on undistributed earnings of foreign subsidiaries and affiliates is made only on those amounts in excess of funds considered to be invested indefinitely. In general, we record income tax expense during interim periods based on our best estimate of the full year’s effective tax rate. However, income tax expense relating to adjustments to Layne’s liabilities for uncertainty in income tax positions for prior reporting periods are accounted for discretely in the interim period in which it occurs. Income tax expense relating to adjustments for current year uncertain tax positions is accounted for as a component of the adjusted annualized effective tax rate. In assessing the need for a valuation allowance, we consider both positive and negative evidence related to the likelihood of realization of the deferred tax assets. The weight given to the positive and negative evidence is commensurate with the extent to which the evidence may be objectively verified. Accounting guidance states that a cumulative loss in recent years is a significant piece of negative evidence that is difficult to overcome in determining that a valuation allowance is not needed against deferred tax assets. As such, it is generally difficult for positive evidence regarding projected future taxable income exclusive of reversing taxable temporary differences to outweigh objective negative evidence of recent financial reporting losses. In preparing future taxable income projections, we consider the periods in which future reversals of existing taxable and deductible temporary differences are likely to occur, future taxable income, taxable income available in prior carryback years and the availability of tax-planning strategies when determining the ability to realize recorded deferred tax assets. Our estimate of uncertainty in income taxes is based on the framework established in the accounting for income taxes guidance. We recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. For tax positions that meet this recognition threshold, we apply judgment, taking into account applicable tax laws and experience in managing tax audits, to determine the amount of tax benefits to recognize in the financial statements. For each position, the difference between the benefit realized on our tax return and the benefit reflected in the financial statements is recorded as a liability in the Consolidated Balance Sheets. This liability is updated at each financial statement date to reflect the impacts of audit settlements and other resolution of audit issues, expiration of statutes of limitation, developments in tax law and ongoing discussions with taxing authorities.
Income (Loss) Per Share	Income (Loss) Per Share – Income (loss) per share is computed by dividing net earnings available to common shareholders by the weighted average number of common shares outstanding during the period. For periods in which we recognize losses, the calculation of diluted loss per share is the same as the calculation of basic loss per share. For periods in which we recognize net income, diluted earnings per common share is computed in the same way as basic earnings per common share except that the denominator is increased to include the number of additional common shares that would be outstanding if all potential common shares had been issued that were dilutive. Options to purchase common stock and nonvested shares are included based on the treasury stock method for dilutive earnings per share except when their effect is antidilutive. The 4.25% Convertible Notes and the 8.0% Convertible Notes (as defined in Note 8 to the Consolidated Financial Statements) are included in the calculation of diluted loss per share if their inclusion is dilutive under the if-converted method. Options to purchase 750,044, 839,715 and 1,015,514 shares have been excluded from weighted average shares for the fiscal years ended January 31, 2017, 2016 and 2015, respectively, as their effect was antidilutive. A total of 1,871,640, 1,407,170 and 487,292 non-vested shares have been excluded from weighted average shares for the fiscal years ended January 31, 2017, 2016 and 2015, respectively, as their effect was antidilutive.
Share-Based Compensation	Share-Based Compensation – We recognize the cost of all share-based instruments in the financial statements based on the calculated fair value of the award. The fair value of share-based compensation granted in the form of stock options is determined using a lattice valuation model. In addition, we granted certain market-based awards during the years ended January 31, 2017, 2016 and 2015, which were valued using the Monte Carlo simulation model. See Note 13 to the Consolidated Financial Statements. Unearned compensation expense associated with the issuance of awards is amortized on a straight-line basis as the restrictions on the stock expire, subject to achievement of certain contingencies.
Research and Development Costs	Research and Development Costs – Research and development costs charged to expense during the fiscal years ended January 31, 2017, 2016 and 2015 were $ 0.1 million in each of the three fiscal years and are recorded in selling, general and administrative expenses.

As a result, it is not practical to allocate a portion of depreciation and amortization to cost of revenues for the presentation of gross profit.
[2]	Loss per share was computed independently for each of the quarters presented. The sum of the quarters may not equal the total year amount due to the impact of changes in average quarterly shares outstanding.
