Summary Of Significant Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 1. Summary of Significant Accounting Policies Basis of financial statement presentation The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries, ventures, and partnerships in which a controlling interest is held. Inter-company transactions and accounts have been eliminated. The Company utilizes the equity method of accounting for companies where its ownership is less than or equal to 50% and significant influence exists. Cash and cash equivalents The Company considers cash and other instruments with maturities of three months or less, when purchased, to be cash and cash equivalents. The Company invests available funds in a manner to maximize returns, preserve investment principal, and maintain liquidity while seeking the highest yield available. Cash and cash equivalents held in non-domestic accounts was approximately $29,700 and $49,233 at December 31, 2015 and 2014, respectively. Included in non-domestic cash equivalents are investments in bank term deposits of approximately $1,939 and $25 at December 31, 2015 and 2014, respectively. The carrying amounts approximated fair value because of the short maturity of the instruments. Inventories Certain inventories are valued at the lower of the last-in, first-out (“LIFO”) cost or market. Approximately 43% in 2015 and 44% in 2014, of the Company’s inventory is valued at average cost or market, whichever is lower. Slow-moving inventory is reviewed and adjusted regularly, based upon product knowledge, physical inventory observation, and the age of the inventory. Property, plant, and equipment Depreciation and amortization are provided on a straight-line basis over the estimated useful lives of 5 to 40 years for buildings and 2 to 10 years for machinery and equipment. Leasehold improvements are amortized over 3 to 13 years, which represent the lives of the respective leases or the lives of the improvements, whichever is shorter. Depreciation expense is recorded within “cost of sales” and “selling and administrative” expenses based upon the particular asset’s use. The Company reviews a long-lived asset for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. There were no material asset impairments recorded for the years ended December 31, 2015, 2014, or 2013. Maintenance, repairs, and minor renewals are charged to operations as incurred. Major renewals and betterments that substantially extend the useful life of the property are capitalized at cost. Upon sale or other disposition of assets, the costs and related accumulated depreciation and amortization are removed from the accounts and the resulting gain or loss, if any, is reflected in income. Allowance for doubtful accounts The allowance for doubtful accounts is recorded to reflect the ultimate realization of the Company’s accounts receivable and includes assessment of the probability of collection and the credit-worthiness of certain customers. Reserves for uncollectible accounts are recorded as part of selling and administrative expenses on the Consolidated Statements of Operations. The Company records a monthly provision for accounts receivable that are considered to be uncollectible. In order to calculate the appropriate monthly provision, the Company reviews its accounts receivable aging and calculates an allowance through application of historic reserve factors to overdue receivables. This calculation is supplemented by specific account reviews performed by the Company’s credit department. As necessary, the application of the Company’s allowance rates to specific customers is reviewed and adjusted to more accurately reflect the credit risk inherent within that customer relationship. Investments Investments in companies in which the Company has the ability to exert significant influence, but not control, over operating and financial policies (generally 20% to 50% ownership) are accounted for using the equity method. Under the equity method, investments are initially recorded at cost and adjusted for dividends and undistributed earnings and losses. The equity method of accounting requires a company to recognize a loss in the value of an equity method investment that is other than a temporary decline. Goodwill and other intangible assets Goodwill is tested annually for impairment or more often if there are indicators of impairment. The goodwill impairment test involves comparing the fair value of a reporting unit to its carrying value, including goodwill. If the carrying amount of the reporting unit exceeds its fair value, a second step is required to measure the goodwill impairment loss. This step compares the implied fair value of the reporting unit’s goodwill to the carrying amount of that goodwill. If the carrying amount of the goodwill exceeds the implied fair value of the goodwill, an impairment loss equal to the excess is recorded as a component of operations. The Company performs its annual impairment tests as of October 1st. During 2015, the Company identified certain triggering events that indicated an interim impairment test was required. As a result of the interim assessment as of September 1, 2015, the Company recorded impairment charges of $80,337 ($63,887 net of taxes) during 2015 related to the acquisitions of IOS and Chemtec. The measurement of goodwill impairment is a Level 3 fair value measurement, as the primary assumptions, including estimates of future revenue growth, gross margin, and EBITDA margin, are not market observable and require management to make judgements regarding future outcomes. Additional information concerning the impairments is set forth in Note 4 to the financial statements. No additional charges were recorded as a result of the 2015 annual impairment test. No goodwill impairment was recognized during 2014 or 2013. The Company has no indefinite-lived intangible assets. The Company reviews a long-lived intangible asset for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. All intangible assets are amortized over their useful lives ranging from 5 to 25 years, with a total weighted average amortization period of approximately 14 years, at December 31, 2015. See Note 4 for additional information including regarding the Company’s other intangible assets. Environmental remediation and compliance Environmental remediation costs are accrued when the liability is probable and costs are estimable. Environmental compliance costs, which principally include the disposal of waste generated by routine operations, are expensed as incurred. Capitalized environmental costs, when appropriate, are depreciated over their useful life. Reserves are not reduced by potential claims for recovery. Claims for recovery are recognized as agreements are reached with third parties or as amounts are received. Reserves are periodically reviewed throughout the year and adjusted to reflect current remediation progress, prospective estimates of required activity, and other factors that may be relevant, including changes in technology or regulations. See Note 19, “Commitments and Contingent Liabilities,” for additional information regarding the Company’s outstanding environmental and litigation reserves. Earnings per share Basic earnings per share is calculated by dividing net income by the weighted average of common shares outstanding during the year. Diluted earnings per share is calculated by using the weighted average of common shares outstanding adjusted to include the potentially dilutive effect of outstanding stock options and restricted stock utilizing the treasury stock method. Revenue recognition The Company’s revenues are comprised of product and service sales as well as products and services provided under long-term contracts. For product and service sales, the Company recognizes revenue when the following criteria have been satisfied; persuasive evidence of a sales arrangement exists, product delivery and transfer of title to the customer has occurred or services have been rendered, the price is fixed or determinable, and collectability is reasonably assured. Generally, product title passes to the customer upon shipment. In limited cases, title does not transfer and revenue is not recognized until the customer has received the products at its physical location. Revenue is recorded net of returns, allowances, customer discounts, and incentives. Sales taxes collected from customers and remitted to governmental authorities are accounted for on a net (excluded from revenues) basis. Shipping and handling costs are included in cost of goods sold. Revenues for products and services under long-term contracts are recognized using the percentage-of-completion method. Sales and gross profit are recognized as work is performed based upon the proportion of actual costs incurred to estimated total project costs. Sales and gross profit are adjusted prospectively for revisions in estimated total project costs and contract values. For certain products and services, the percentage of completion is based upon actual labor costs as a percentage of estimated total labor costs. At the time a loss contract becomes known, the entire amount of the estimated loss is recognized in the Consolidated Statement of Operations. Revenue recognition involves judgments, including assessments of expected returns, the likelihood of nonpayment, and estimates of expected costs and profits on long-term contracts. In determining when to recognize revenue, we analyze various factors, including the specifics of the transaction, historical experience, creditworthiness of the customer, and current market and economic conditions. Changes in judgments on these factors could impact the timing and amount of revenue recognized with a resulting impact on the timing and amount of associated income. Costs in excess of billings are classified as work-in-process inventory. Projects with billings in excess of costs are recorded within deferred revenue. Deferred revenue Deferred revenue consists of customer payments received for which the revenue recognition criteria have not yet been met as well as billings in excess of costs on percentage of completion projects. Advanced payments from customers typically relate to contracts with respect to which the Company has significantly fulfilled its obligations, but due to the Company’s continuing involvement with the project, revenue is precluded from being recognized until title, ownership, and risk of loss have passed to the customer. Fair value of financial instruments The Company’s financial instruments consist of cash equivalents, accounts receivable, accounts payable, interest rate swap agreements, and debt. The carrying amounts of the Company’s financial instruments at December 31, 2015 and 2014 approximate fair value. See Note 18, “Fair Value Measurements,” for additional information. Stock-based compensation The Company applies the provisions of FASB ASC 718, “Compensation – Stock Compensation,” to account for the Company’s share-based compensation. Under the guidance, share-based compensation cost is measured at the grant date based on the calculated fair value of the award. The expense is recognized over the employees’ requisite service period, generally the vesting period of the award. See Note 15, “Stare-based Compensation,” for additional information. Product warranty The Company maintains a current warranty liability for the repair or replacement of defective products. For certain manufactured products, an accrual is made on a monthly basis as a percentage of cost of sales based upon historical experience. For long-lived construction products, a warranty is established when the claim is known and quantifiable. The product warranty accrual is periodically adjusted based on the identification or resolution of known individual product warranty claims or due to changes in the Company’s historical warranty experience. At December 31, 2015 and 2014, the product warranty reserve was $8,755 and $11,500, respectively. See Note 19, “Commitments and Contingencies” for additional information regarding the product warranty. Income taxes Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of assets and liabilities and their respective tax bases. Deferred taxes are measured using enacted tax laws and rates expected to be in effect when such differences are recovered or settled. The effect of a change in tax rates on deferred taxes is recognized in income in the period that includes the enactment date of the change. The Company makes judgments regarding the recognition of deferred tax assets and the future realization of these assets. As prescribed by Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 740 “Income Taxes” and applicable guidance, valuation allowances must be provided for those deferred tax assets for which it is more likely than not (a likelihood more than 50%) that some portion or all of the deferred tax assets will not be realized. The guidance requires the Company to evaluate positive and negative evidence regarding the recoverability of deferred tax assets. Determination of whether the positive evidence outweighs the negative evidence and quantification of the valuation allowance requires the Company to make estimates and judgments of future financial results. The Company evaluates all tax positions taken on its federal, state, and foreign tax filings to determine if the position is more likely than not to be sustained upon examination. For positions that meet the more likely than not to be sustained criteria, the largest amount of benefit to be realized upon ultimate settlement is determined on a cumulative probability basis. A previously recognized tax position is derecognized when it is subsequently determined that a tax position no longer meets the more likely than not threshold to be sustained. The evaluation of the sustainability of a tax position and the expected tax benefit is based on judgment, historical experience, and various other assumptions. Actual results could differ from those estimates upon subsequent resolution of identified matters. The Company accrues interest and penalties related to unrecognized tax benefits in its provision for income taxes. Foreign currency translation The assets and liabilities of our foreign subsidiaries are measured using the local currency as the functional currency and are translated into U.S. dollars at exchange rates as of the balance sheet date. Income statement amounts are translated at the weighted-average rates of exchange during the year. The translation adjustment is accumulated as a separate component of accumulated other comprehensive income (loss). Foreign currency transaction gains and losses are included in determining net income. Included in net income for the years ended December 31, 2015, 2014, and 2013 were foreign currency transaction gains of approximately $1,616, $422, and $433, respectively. Research and development The Company expenses research and development costs as costs are incurred. For the years ended December 31, 2015, 2014, and 2013, research and development expenses were $3,937, $3,096, and $3,154, respectively, and were principally related to the Company’s friction management and railroad monitoring system products. Use of estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Reclassifications Certain accounts in the prior year consolidated financial statements have been reclassified for comparative purposes principally to conform to the presentation in the current year period. These reclassifications include separately presenting sales of services and cost of services sold to reflect the Company’s increased service offerings attributable to the recent acquisitions disclosed in Note 3 and a change in GAAP, as further described below. Recently issued accounting guidance In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2014-09, “Revenue from Contracts with Customers (Topic 606)” (“ASU 2014-09”), which supersedes the revenue recognition requirements in Accounting Standards Codification 605, “Revenue Recognition.” ASU 2014-09 is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. It also requires additional disclosure about the nature, amount, timing, and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. ASU 2014-09 is effective for fiscal years beginning after December 15, 2017, including interim periods within that reporting period. The Company is currently evaluating its implementation approach and assessing the impact of ASU 2014-09 on our financial position and results of operations. In July 2015, the FASB issued ASU No. 2015-11, “Inventory (Topic 330): Simplifying the Measurement of Inventory.” The pronouncement was issued to simplify the measurement of inventory and changes the measurement from lower of cost or market to lower of cost and net realizable value. This pronouncement is effective for reporting periods beginning after December 15, 2016. The adoption of ASU 2015-11 is not expected to have a significant impact on our financial position or results of operations. Recently adopted accounting guidance In April 2015, the FASB issued ASU No. 2015-03, “Interest-Imputation of Interest (Topic 835-30): Simplifying the Presentation of Debt Issuance Costs”, which requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. Debt issuance costs related to line of credit arrangements may continue to be reflected as an asset. The recognition and measurement guidance of debt issuance costs are not affected by the amendments in this update. The standard is effective for financial statements issued for annual periods beginning after December 15, 2015, and interim periods within those annual periods. The Company early adopted the new guidance in the fourth quarter of 2015 and there was no impact to the consolidated financial statements from the adoption of this guidance. In September 2015, the FASB issued ASU No. 2015-16 “Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments” (“ASU 2015-16”). ASU 2015-16 requires that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. Prior to the issuance of the standard, entities were required to retrospectively apply adjustments made to provisional amounts recognized in a business combination. ASU 2015-16 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2015, and early adoption is permitted. Accordingly, the standard is effective for the Company on January 1, 2016. The Company early adopted the new guidance in the fourth quarter of 2015 and there was no impact to the consolidated financial statements from the adoption of this guidance. In November 2015, the FASB issued ASU No. 2015-17, “Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes” ("ASU 2015-17"). This new guidance requires businesses to classify deferred tax liabilities and assets on their balance sheets as noncurrent. Under existing accounting, a business must separate deferred income tax liabilities and assets into current and noncurrent. ASU 2015-17 was issued as a way to simplify the way businesses classify deferred tax liabilities and assets on their balance sheets. Public companies must apply ASU 2015-17 to fiscal years beginning after December 15, 2016. Companies must follow the requirements for interim periods within those fiscal years, but early adoption at the beginning of an interim or annual period is allowed for all entities. The Company adopted this guidance during the fourth quarter of 2015 on a retrospective basis, which resulted in the reclassification of $3,497 current deferred tax assets and $77 current deferred tax liabilities to non-current as of December 31, 2014.

BUSINESS SEGMENTS

Note 2.

Business Segments

The Company is a leading manufacturer, fabricator, and distributor of products and services for rail, construction, energy, and utility markets. The Company is organized and evaluated by product group, which is the basis for identifying reportable segments. Each segment represents a revenue-producing component of the Company for which separate financial information is produced internally that is subject to evaluation by the Company’s chief operating decision maker in deciding how to allocate resources. Each segment is evaluated based upon their segment profit contribution to the Company’s consolidated results.

As a result of recently completed acquisitions, during the first quarter of 2015, the Company renamed the Rail Products and Tubular Products business segments to be Rail Products and Services and Tubular and Energy Services, respectively. The name changes principally reflect the additional businesses conducted by those segments as a result of acquisitions that have enhanced our product and service offerings within the rail and energy markets. Excluding the addition of current year acquisitions, there were no changes to the divisions that have been aggregated within the segments nor were there changes to the historical reportable segment results.

The Company markets its products directly in all major industrial areas of the United States, Canada, and Europe, primarily through an internal sales force.

The Company’s Rail Products and Services segment provides a full line of new and used rail, trackwork, and accessories to railroads, mines, and other customers in the rail industry. The Rail segment also designs and produces insulated rail joints, power rail, track fasteners, concrete railroad ties, coverboards, and special accessories for mass transit and other rail systems. In addition, the Rail Products and Services segment engineers, manufactures, and assembles friction management products and railway wayside data collection and management systems.

The Company’s Construction Products segment sells and rents steel sheet piling, H-bearing pile, and other piling products for foundation and earth retention requirements. The Company’s Fabricated Products division sells bridge decking, bridge railing, structural steel fabrications, expansion joints, bridge forms, and other products for highway construction and repair. The concrete products businesses produce precast concrete buildings and a variety of specialty precast concrete products.

The Company’s Tubular and Energy Services segment provides pipe coatings for natural gas pipelines and utilities, upstream test and inspection services, precision measurement systems for the oil and gas market, and produces threaded pipe products for the oil and gas markets as well as industrial water well and irrigation markets.

The following table illustrates net sales, profit (loss), assets, depreciation/amortization, and expenditures for long-lived assets of the Company by segment for the years ended or at December 31, 2015, 2014, and 2013. Segment profit is the earnings from operations before income taxes and includes internal cost of capital charges for net assets used in the segment at a rate of generally 1% per month excluding recently acquired businesses. The internal cost of capital charges are eliminated during the consolidation process. The accounting policies of the reportable segments are the same as those described in the summary of significant accounting policies except that the Company accounts for inventory on a First-In, First-Out (“FIFO”) basis at the segment level compared to a Last-In, First-Out (“LIFO”) basis at the consolidated level.

Acquisition Summary

Each transaction was accounted for under the acquisition method of accounting under U.S. generally accepted accounting principles which requires an acquiring entity to recognize, with limited exceptions, all of the assets acquired and liabilities assumed in a transaction at fair value as of the acquisition date. Goodwill primarily represents the value paid for each acquisition’s enhancement to the Company’s product and service offerings and capabilities, as well as a premium payment related to the ability to control the acquired assets. The Company has concluded that intangible assets and goodwill values resulting from the Chemtec, FWO, and Carr transactions will be deductible for tax purposes.

The Company incurred $760 and $2,240 of acquisition-related costs which are included in the results of operations within selling and administrative costs for the years ended December 31, 2015 and 2014.

The following unaudited pro forma consolidated income statement presents the Company’s results as if the acquisitions of IOS, Tew, and Chemtec had occurred on January 1, 2014. The 2015 pro forma results include the impact of the current year impairment of goodwill as further described in Note 4.

GOODWILL AND OTHER INTANGIBLE ASSETS

Note 4.

Goodwill and Other Intangible Assets

The following table represents the goodwill balance by reportable segment:



		Rail Products and Services		Construction Products		Tubular and Energy Services		Total
Balance at December 31, 2014	$	38,956	$	5,147	$	38,846	$	82,949
Acquisitions		9,594		-		69,908		79,502
Foreign currency translation impact		(362)		-		-		(362)

Balance at December 31, 2015	$	48,188	$	5,147	$	28,417	$	81,752

The Company performs goodwill impairment tests annually during the fourth quarter, and also performs interim goodwill impairment tests if it is determined that it is more likely than not that the fair value of a reporting unit is less than the carrying amount. Qualitative factors are assessed to determine whether it is more likely than not that the fair value of a reporting unit is less than the carrying amount. During the third quarter of 2015, the Company’s IOS and Chemtec reporting units underperformed against their projections and revised their forecasts downward. Additionally, in August 2015, the Company revised its full year outlook as a result of trends in the energy market as well as the loss of sales to Union Pacific Railroad (“UPRR”). The impact of these factors led to a decline in the Company’s market capitalization which fell below the shareholder’s equity value. The Company concluded that the aggregation of these events were indications of potential impairments.

Based upon these indicators, with the assistance of an independent valuation firm, the Company performed an interim test for impairment of goodwill as of September 1, 2015. The valuation included the use of both the income and market approach. The Company applied greater weighting to the income approach as the Company believes it is the most reliable indication of value as it captures forecasted revenues and earnings for the reporting units in the projection period that the market approach may not directly incorporate.

The results of the test indicated that the IOS and Chemtec reporting units’ respective fair values were less than their carrying values. The fair values of all other reporting units that maintain goodwill exceeded their respective carrying values and were not at risk of impairment. As a result of the impact of the downturn within the energy markets on both reporting units, the expectations of a prolonged period before recovery, and the reduction in active U.S. land oil rig count, which specifically impacted the IOS reporting unit, the near term projections of these reporting units have deteriorated and the expected future growth of each of these reporting units was insufficient to support the carrying values.

The Company compared the implied fair values of the IOS and Chemtec goodwill amounts to the carrying amounts of that goodwill. The fair values of the IOS and Chemtec reporting units were allocated to all of the assets and liabilities of the respective reporting unit as if IOS and Chemtec had been acquired in business combinations as of the test date and the fair value was the purchase price paid to acquire each reporting unit. As a result of this valuation, it was determined that the carrying amounts of IOS’s and Chemtec’s goodwill exceeded the implied fair values of that goodwill. The Company recognized a non-cash goodwill impairment charge of $80,337 ($63,887 net of taxes) to write down the carrying values to the implied fair values, of which $69,908 represents the full carrying value of goodwill related to the IOS acquisition and the remaining $10,429 relates to the Chemtec reporting unit. No additional impairments were triggered as a result of the Company’s 2015 annual impairment test.

The Company performed a recoverability test on the long-lived tangible and definite lived intangible assets related to the IOS and Chemtec acquisitions and concluded that no impairment existed. The Company will continue to monitor these assets, including their respectful useful lives, in future periods.

The following table represents the gross intangible assets balance by reportable segment at December 31:

INVESTMENTS

Note 8.

Investments

The Company is a member of a joint venture, L B Pipe and Coupling Products, LLC (“LB Pipe JV”), in which it maintains a 45% ownership interest. The LB Pipe JV manufactures, markets, and sells various precision coupling products for the energy, utility, and construction markets and is scheduled to terminate on June 30, 2019.

Under applicable guidance for variable interest entities in ASC 810, “Consolidation,” the Company determined that the LB Pipe JV is a variable interest entity. The Company concluded that it is not the primary beneficiary of the variable interest entity, as the Company does not have a controlling financial interest and does not have the power to direct the activities that most significantly impact the economic performance of the LB Pipe JV. Accordingly, the Company concluded that the equity method of accounting remains appropriate.

During the years ended December 31, 2015 and 2014, each of the LB Pipe JV members received proportional distributions from the LB Pipe JV. The Company’s 45% ownership interest resulted in cash distributions of $90 and $630 as of December 31, 2015 and 2014, respectively. There were no changes to the members’ ownership interests as a result of the distribution.

The Company recorded equity in the (loss) income of the LB Pipe JV of approximately ($410), $1,286 and $1,316 for the years ended December 31, 2015, 2014, and 2013, respectively.

As of December 31, 2015 and 2014, the Company had a nonconsolidated equity method investment of $5,246 and $5,746, respectively, in the LB Pipe JV and other investments totaling $75 and $78 as of December 31, 2015 and 2014, respectively.

The Company’s exposure to loss results from its capital contributions, net of the Company’s share of the LB Pipe JV’s income or loss, and its net investment in the direct financing lease covering the facility used by the LB Pipe JV for its operations. The carrying amounts with the maximum exposure to loss of the Company at December 31, 2015 and 2014, respectively, are as follows:



		2015		2014

LB Pipe JV equity method investment	$	5,246	$	5,746
Net investment in direct financing lease		995		1,117
	$	6,241	$	6,863

The Company is leasing five acres of land and two facilities to the LB Pipe JV through June 30, 2019, with a 5.5 year renewal period. The current monthly lease payments, including interest, approximate $17, with a balloon payment of approximately $488, which is required to be paid at the termination of the lease, allocated over the renewal period, or during the initial term of the lease. This lease qualifies as a direct financing lease under the applicable guidance in ASC 840-30, Leases.

The following is a schedule of the direct financing minimum lease payments for the years 2016 and thereafter



		Minimum Lease Payments
2016	$	131
2017		140
2018		150
2019		574
	$	995

As a result of the November 23, 2015 acquisition of Tew Plus, the Company remeasured its 25% equity investment in Tew Plus resulting in other income of $580 for the period ended December 31, 2015. Refer to Note 20, “Other Income,” for additional information on the gain.

Deferred Revenue	Note 9. Deferred Revenue Deferred revenue of $6,934 and $8,034 at December 31, 2015 and 2014, respectively, consists of customer payments received for which the revenue recognition criteria have not yet been met as well as billings in excess of costs on percentage of completion projects. Advanced payments from customers typically relate to contracts with respect to which the Company has significantly fulfilled its obligations, but due to the Company’s continuing involvement with the project, revenue is precluded from being recognized until title, ownership, and risk of loss have passed to the customer.

Borrowings

United States

On March 13, 2015, L.B. Foster Company, its domestic subsidiaries, and certain of its Canadian subsidiaries (“L.B. Foster”) entered into an amended and restated $335,000 Revolving Credit Facility Credit Agreement (“Amended Credit Agreement”) with PNC Bank, N.A., Bank of America, N.A., Wells Fargo Bank, N.A., Citizens Bank of Pennsylvania, and Branch Banking and Trust Company. This Amended Credit Agreement modifies the prior revolving credit facility, which had a maximum credit line of $200,000. The Amended Credit Agreement provides for a five-year, unsecured revolving credit facility that permits borrowings of up to $335,000 for the U.S. borrowers and a sublimit of the equivalent of $25,000 U.S. dollars that is available to the Canadian borrowers. The Amended Credit Agreement’s accordion feature permits L.B. Foster to increase the available revolving borrowings under the facility by up to an additional $100,000 subject to L.B. Foster’s receipt of increased commitments from existing or new lenders and to certain conditions being satisfied.

Borrowings under the Amended Credit Agreement will bear interest at rates based upon either the base rate or Euro-rate plus applicable margins. Applicable margins are dictated by the ratio of L.B. Foster’s indebtedness less consolidated cash on hand to L.B. Foster’s consolidated EBITDA, as defined in the underlying Amended Credit Agreement. The base rate is the highest of (a) PNC Bank’s prime rate, (b) the Federal Funds Rate plus 0.50% or (c) the daily Euro-rate (as defined in the Amended Credit Agreement) plus 1.00%. The base rate and Euro-rate spreads range from 0.00% to 1.50% and 1.00% to 2.50%, respectively.

The Amended Credit Agreement includes two financial covenants: (a) Leverage Ratio, defined as L.B. Foster’s Indebtedness less consolidated cash on hand, in excess of $15,000, divided by L.B. Foster’s consolidated EBITDA, which must not exceed 3.25 to 1.00 and (b) Minimum Interest Coverage, defined as consolidated EBITDA less Capital Expenditures divided by consolidated interest expense, which must be no less than 3.00 to 1.00.

The Amended Credit Agreement permits L.B. Foster to pay dividends, distributions, and make redemptions with respect to its stock provided no event of default or potential default (as defined in the Amended Credit Agreement) has occurred prior to or after giving effect to the dividend, distribution, or redemption. Dividends, distributions, and redemptions are capped at $25,000 per year when funds are drawn on the facility. If no drawings on the facility exist, dividends, distributions, and redemptions in excess of $25,000 per year are subjected to a limitation of $75,000 in the aggregate over the life of the facility. The $75,000 aggregate limitation also permits certain loans, investments, and acquisitions.

Other restrictions exist at all times including, but not limited to, limitation of L.B. Foster’s sale of assets, other indebtedness incurred by either the borrowers or the non-borrower subsidiaries of L.B. Foster, guarantees, and liens.

The Company had $165,000 outstanding borrowings under the Amended Credit Agreement at December 31, 2015 and had available borrowing capacity of $169,474 at December 31, 2015. As of December 31, 2014, the Company had $24,200 in outstanding borrowings and an available borrowing capacity of $175,375 under the previous revolving facility with a borrowing capacity of $200,000.

At December 31, 2015, the Company was in compliance with the Amended Credit Agreement’s covenants.

Letters of Credit

At December 31, 2015 and 2014, the Company had outstanding letters of credit of approximately $526 and $425, respectively.

United Kingdom

A subsidiary of the Company has a credit facility with NatWest Bank for its United Kingdom operations which includes an overdraft availability of £1,500 pounds sterling (approximately $2,210 at December 31, 2015). This credit facility supports the United Kingdom’s working capital requirements and is collateralized by substantially all of the assets of its United Kingdom operations. The interest rate on this facility is the financial institution’s base rate plus 1.50%. Outstanding performance bonds reduce availability under this credit facility. There were no outstanding borrowings under this credit facility at December 31, 2015, however, there were $16 in outstanding guarantees (as defined in the underlying agreement) at December 31, 2015. This credit facility was renewed and amended during the fourth quarter of 2015 to include Tew and Tew Plus as parties to the agreement. All other underlying terms and conditions remained unchanged as a result of the renewal. It is the Company’s intention to renew this credit facility with NatWest Bank during the annual review in 2016.

The United Kingdom loan agreements contain certain financial covenants that require that subsidiary to maintain senior interest and cash flow coverage ratios. The subsidiary was in compliance with these financial covenants at December 31, 2015 and 2014. The subsidiary had available borrowing capacity of $2,194 and $2,337 at December 31, 2015 and 2014, respectively.

At December 31, 2015, the Company has not recorded deferred U.S. income taxes or foreign withholding taxes on $57,781 of undistributed earnings of its foreign subsidiaries. It is management’s intent and practice to indefinitely reinvest such earnings outside of the U.S. Determination of the amount of any unrecognized deferred income tax liability associated with these undistributed earnings is not practicable because of the complexities of the hypothetical calculation.

(Loss) income before income taxes, as shown in the accompanying consolidated statements of operations, includes the following components:



		2015		2014		2013


Domestic	$	(55,061)	$	30,766	$	37,306

At December 31, 2015 and 2014, the tax benefit of net operating loss carryforwards available for state income tax purposes was $324 and $74, respectively. The state net operating loss carryforwards will expire in various years from 2024 through 2035. At December 31, 2015, the Company has foreign net operating loss carryforwards of $1,320, which may be carried forward indefinitely. The Company has foreign tax credit carryforwards in the amount of $272 that will expire in 2024 through 2026. The Company anticipates utilizing these operating loss and credit carryforwards prior to their expiration and, therefore, has not provided a valuation allowance for these amounts.

The following table provides a reconciliation of unrecognized tax benefits at December 31, 2015 and 2014:



		2015		2014


Unrecognized tax benefits at beginning of period:	$	1,013	$	1,509
Increases based on tax positions for prior periods		147		18
Decreases based on tax positions for prior periods		-		(325)
Decreases related to settlements with taxing authorities		(578)		(126)
Decreases as a result of a lapse of the applicable statute of limitations		-		(63)
Balance at end of period	$	582	$	1,013

The total amount of unrecognized tax benefits that, if recognized, would affect the effective tax rate is $582 at December 31, 2015. The Company accrues interest and penalties related to unrecognized tax benefits in its provision for income taxes. At December 31, 2015 and 2014, the Company had accrued interest and penalties related to unrecognized tax benefits of $443 and $335, respectively. At December 31, 2015, the Company does not expect any material increases or decreases to its unrecognized tax benefits within the next 12 months. Ultimate realization of this decrease is dependent upon the occurrence of certain events, including the completion of audits by tax authorities and expiration of statutes of limitations.

The Company files income tax returns in the United States and in various state, local and foreign jurisdictions. The Company is subject to federal income tax examinations for the period 2012 and forward. With respect to the state, local, and foreign filings, certain entities of the Company are subject to income tax examinations for the periods 2011 and forward.

Share-based Compensation [Abstract]

Share-based Compensation

Note 15.

Share-based Compensation

The Company applies the provisions of FASB ASC 718, Compensation – Stock Compensation, to account for the Company’s share-based compensation. Share-based compensation cost is measured at the grant date based on the calculated fair value of the award and is recognized over the employees’ requisite service period. The Company recorded share-based compensation expense of $1,471, $3,007 and $2,156 for the years ended December 31, 2015, 2014, and 2013, respectively, related to fully-vested stock awards, restricted stock awards, and performance unit awards. At December 31, 2015, unrecognized compensation expense for awards the Company expects to vest approximated $2,611. The Company will recognize this expense over the upcoming 3.5 year period through June 2019.

Shares issued as a result of vested stock-based compensation generally will be from previously issued shares which have been reacquired by the Company and held as Treasury stock or authorized but previously unissued common stock.

The excess tax benefit realized for the tax deduction from share-based compensation approximated $253, $336, and $203 for the years ended December 31, 2015, 2014, and 2013, respectively. This excess tax benefit is included in cash flows from financing activities in the Consolidated Statements of Cash Flows.

At December 31, 2015, the Company had stock awards issued pursuant to the 2006 Omnibus Incentive Plan as amended and restated in October 2013 (“Omnibus Plan”). The Omnibus Plan allows for the issuance of 900,000 shares of common stock through the granting of stock options or stock awards (including performance units convertible into stock) to key employees and directors at no less than 100% of fair market value on the date of the grant. The Omnibus Plan provides for the granting of “nonqualified options” with a duration of not more than ten years from the date of grant. The Omnibus Plan also provides that, unless otherwise set forth in the option agreement, stock options are exercisable in installments of up to 25% annually beginning one year from the date of grant. No stock options have been granted under the Omnibus Plan and, as such, there was no share-based compensation expense related to stock options recorded in 2015, 2014, or 2013

The Company also had 7,500 outstanding stock option awards that were granted under the former 1998 Long-Term Incentive Plan for Officers and Directors, amended and restated in May 2006 (“1998 Plan”). During 2015, all 7,500 outstanding stock option awards were exercised prior to their expiration. No future grants are permitted under the expired 1998 Plan and the Company currently makes equity awards under the Omnibus Plan.

Stock Option Awards

Certain information for the three years ended December 31, 2015 relative to employee stock options is summarized as follows:



	2015	2014	2013
Number of shares under the plans:
Outstanding and exercisable at beginning of year	7,500	18,750	22,500
Granted	-	-	-
Canceled	-	-	-
Exercised	(7,500)	(11,250)	(3,750)
Outstanding and exercisable at end of year	-	7,500	18,750

The weighted average exercise price per share of the stock options exercised in 2015, 2014, and 2013 were $9.08, $11.67, and $9.30, respectively. The total intrinsic value of stock options exercised during the years ended December 31, 2015, 2014, and 2013 was $253, $426, and $124, respectively.

Fully-Vested Stock Awards

Non-employee directors are automatically awarded fully vested shares of the Company’s common stock on each date the non-employee directors are elected at the annual shareholders’ meeting to serve as directors.

The non-employee directors were granted a total of 14,000, 10,182, and 9,960 fully-vested shares for the years ended December 31, 2015, 2014, and 2013, respectively. Compensation expense recorded by the Company related to fully-vested stock awards to non-employee directors was approximately $534, $488, and $450 for the years ended December 31, 2015, 2014, and 2013, respectively.

The weighted average fair value of all the fully-vested stock grants awarded was $38.15, $47.94, and $45.16 per share for 2015, 2014, and 2013, respectively.

Restricted Stock Awards and Performance Unit Awards

Under the amended and restated 2006 Omnibus Plan, the Company grants eligible employees restricted stock and performance unit awards. The forfeitable restricted stock awards granted prior to March 2015 generally time-vest after a four year holding period, and those granted in March 2015 generally time-vest ratably over a three-year period, unless indicated otherwise by the underlying restricted stock agreement. Performance unit awards are offered annually under separate three-year long-term incentive programs. Performance units are subject to forfeiture and will be converted into common stock of the Company based upon the Company’s performance relative to performance measures and conversion multiples as defined in the underlying program. If the Company’s estimate of the number of performance stock awards expected to vest changes in a subsequent accounting period, cumulative compensation expense could increase or decrease. The change will be recognized in the current period for the vested shares and would change future expense over the remaining vesting period.

The following table summarizes the restricted stock award and performance unit award activity for the three-year periods ended December 31, 2015, 2014, and 2013:


	Restricted	Performance		Weighted Average
	Stock	Stock		Grant Date
	Units	Units		Fair Value
Outstanding at January 1, 2013	176,646	59,725	$	31.65

Adjustment for incentive awards not expected to vest	-	(53,228)		43.26
Canceled	(5,000)	-		44.84
Outstanding at December 31, 2015	93,817	35,999	$	39.66

Performance units are subject to forfeiture and will be converted into common stock of the Company based upon the Company’s performance relative to performance measures and conversion multiples as defined in the underlying plan. The aggregate fair value in the above table is based upon achieving 100% of the performance targets as defined in the underlying plan. During 2014, the Company reversed $702 of incentive compensation costs under its separate three-year long-term incentive plans caused by the impact of the product warranty charges on Company performance, as it related to the awards’ underlying performance conditions. More information on the product warranty charge can be found in Note 19, “Commitments and Contingent Liabilities”.

Excluding the fully-vested stock awards granted to non-employee directors, the Company recorded compensation expense of $937, $2,519, and $1,706, respectively, for the periods ended December 31, 2015, 2014, and 2013 related to restricted stock and performance unit awards.



	2015	2014	2013
Number of shares available for future grant:
Beginning of year	469,840	513,280	517,280
End of year	407,307	469,840	513,280

The Company issued, pursuant to the Omnibus Plan, approximately 14,000 fully-vested shares during 2014 which were earned under the 2011 – 2013 three -year long-term incentive plan. This non-cash transaction of $454 was reflected as a decrease to Treasury stock in the Consolidated Balance Sheet at December 31, 2014.

RETIREMENT PLANS

Note 16.

Retirement Plans

The Company has seven retirement plans which cover its hourly and salaried employees in the United States: three defined benefit plans (one active / two frozen) and four defined contribution plans. Employees are eligible to participate in the appropriate plan based on employment classification. The Company's contributions to the defined benefit and defined contribution plans are governed by the Employee Retirement Income Security Act of 1974 (“ERISA”), policy and investment guidelines of the applicable plan. The Company’s policy is to contribute at least the minimum in accordance with the funding standards of ERISA.

The Company’s subsidiary, L.B. Foster Rail Technologies (“Rail Technologies”), maintains two defined contribution plans for its employees in Canada, as well as a post-retirement benefit plan. In the United Kingdom, Rail Technologies maintains two defined contribution plans and a defined benefit plan. These plans are discussed in further detail below.

United States Defined Benefit Plans

The following tables present a reconciliation of the changes in the benefit obligation, the fair market value of the assets, and the funded status of the plans, as of December 31, 2015 and 2014:

Amounts recognized in the consolidated balance sheet consist of:
Other long-term liabilities	$	(3,524)	$	(3,720)



Amounts recognized in accumulated other comprehensive income consist of:
Net loss	$	3,993	$	4,429
Prior service cost		-		3
	$	3,993	$	4,432

The actuarial loss included in accumulated other comprehensive loss that will be recognized in net periodic pension cost during 2016 is $276, before taxes.

Net periodic pension costs for the three years ended December 31, 2015 are as follows:



		2015		2014		2013
Components of net periodic benefit cost:
Service cost	$	38	$	23	$	33
Interest cost		742		771		707
Expected return on plan assets		(816)		(968)		(856)
Amortization of prior service cost		3		1		1
Recognized net actuarial loss		275		65		212
Net periodic pension cost (income)	$	242	$	(108)	$	97

The weighted average assumptions in the following table represent the rates used to develop the actuarial present value of the projected benefit obligation for the year listed and also the net periodic benefit cost for the following year.



	2015		2014		2013
Discount rate	4.3	%	4.0	%	4.9	%
Expected rate of return on plan assets	5.2	%	5.5	%	6.5	%

The expected long-term rate of return is based on numerous factors including the target asset allocation for plan assets, historical rate of return, long-term inflation assumptions, and current and projected market conditions. The decline in the expected rate of return on plan assets reflects a shift in the Plans’ investment strategy toward a higher focus on fixed income investments.

Amounts applicable to the Company’s pension plans with accumulated benefit obligations in excess of plan assets are as follows at December 31:



		2015		2014

Projected benefit obligation	$	17,759	$	18,925
Accumulated benefit obligation		17,759		18,925
Fair value of plan assets	$	14,235	$	15,205

Plan assets consist primarily of various fixed income and equity investments. The Company’s primary investment objective is to provide long-term growth of capital while accepting a moderate level of risk. The investments are limited to cash and cash equivalents, bonds, preferred stocks, and common stocks. The investment target ranges and actual allocation of pension plan assets by major category at December 31, 2015 and 2014 are as follows:



	Target		2015		2014
Asset Category
Cash and cash equivalents	0 - 10	%	9	%	2	%
Total fixed income funds	25 - 50		35		34
Total mutual funds and equities	50 - 70		56		64
Total			100	%	100	%

In accordance with the fair value disclosure requirements with FASB ASC 820, “Fair Value Measurements and Disclosures,” the following assets were measured at fair value on a recurring basis at December 31, 2015 and 2014. Additional information regarding FASB ASC 820 and the fair value hierarchy can be found in Note 18, Fair Value Measurements.




		2015		2014

Asset Category
Cash and cash equivalents	$	1,248	$	347

Corporate bonds		4,926		5,194
Total fixed income funds		4,926		5,194
Equity funds and equities

Common stock		-		6,098
Total mutual funds and equities		8,061		9,664
Total	$	14,235	$	15,205

Cash equivalents. The Company uses quoted market prices to determine the fair value of these investments in interest-bearing cash accounts and they are classified in Level 1 of the fair value hierarchy. The carrying amounts approximate fair value because of the short maturity of the instruments.

Fixed income funds. Investments within the fixed income funds category consist of fixed income corporate debt. The Company uses quoted market prices to determine the fair value of these fixed income funds. These instruments consist of exchange-traded government and corporate bonds and are classified in Level 1 of the fair value hierarchy.

Equity funds and equities. The valuation of investments in registered investment companies is based on the underlying investments in securities. Securities traded on security exchanges are valued at the latest quoted sales price. Securities traded in the over-the-counter market and listed securities for which no sale was reported on that date are valued at the average of the last reported bid and ask quotations. These investments are classified in Level 1 of the fair value hierarchy.

The Company currently does not anticipate contributions to its United States defined benefit plans in 2016.

The following benefit payments are expected to be paid:

United Kingdom Defined Benefit Plan

The Portec Rail Products (UK) Limited Pension Plan covers certain current employees, former employees, and retirees. The plan has been frozen to new entrants since April 1, 1997 and also covers the former employees of a merged plan after January 2002. Benefits under the plan were based on years of service and eligible compensation during defined periods of service. Our funding policy for the plan is to make minimum annual contributions required by applicable regulations.

The Company has estimated the long-term rate of return on plan assets based primarily on historical returns on plan assets, adjusted for changes in target portfolio allocations, and recent changes in long-term interest rates based on publicly available information.

Plan assets are invested by the trustees in accordance with a written statement of investment principles. This statement permits investment in equities, corporate bonds, United Kingdom government securities, commercial property, and cash, based on certain target allocation percentages. Asset allocation is primarily based on a strategy to provide steady growth without undue fluctuations. The target asset allocation percentages for 2015 are as follows:



	Portec Rail
	Plan
Equity securities	Up to 100%
Commercial property	Not to exceed 50%
U.K. Government securities	Not to exceed 50%
Cash	Up to 100%

Plan assets held within the Portec Rail Plan consist of cash and marketable securities that have been classified as Level 1 of the fair value hierarchy. All other plan assets have been classified as Level 2 of the fair value hierarchy.

The plan assets by category for the two years ended December 31, 2015 and 2014 are as follows:




		2015		2014
Asset Category
Cash and cash equivalents	$	242	$	218
Equity securities		2,656		2,156
Bonds		1,301		1,899
Commercial property		2,462		2,484
Total	$	6,661	$	6,757

United Kingdom regulations require trustees to adopt a prudent approach to funding required contributions to defined benefit pension plans. The Company anticipates making contributions of $271 to the Portec Rail Plan during 2016.

The following estimated future benefits payments are expected to be paid under the Portec Rail Plan:

Fair Value Measurements [Abstract]

FAIR VALUE MEASUREMENTS

Note 18.

Fair Value Measurements

The Company determines the fair value of assets and liabilities based on the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants. The fair values are based on assumptions that market participants would use when pricing an asset or liability, including assumptions about risk and the risks inherent in valuation techniques and the inputs to valuations. The fair value hierarchy is based on whether the inputs to valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s own assumptions of what market participants would use. The fair value hierarchy includes three levels of inputs that may be used to measure fair value as described below.

Level 1: Quoted market prices in active markets for identical assets or liabilities.

Level 2: Observable market-based inputs or unobservable inputs that are corroborated by market data.

Level 3: Unobservable inputs that are not corroborated by market data.

The classification of a financial asset or liability within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement.

The Company has an established process for determining fair value for its financial assets and liabilities, principally cash and cash equivalents and interest rate swaps. Fair value is based on quoted market prices, where available. If quoted market prices are not available, fair value is based on assumptions that use as inputs market-based parameters. The following section describes the valuation methodologies used by the Company to measure different financial instruments at fair value, including an indication of the level in the fair value hierarchy in which each instrument is generally classified. Where appropriate, the description includes details of the key inputs to the valuations and any significant assumptions.

Cash equivalents. Included within “Cash and cash equivalents” are investments in non-domestic term deposits. The carrying amounts approximate fair value because of the short maturity of the instruments.

LIBOR-Based interest rate swaps. To reduce the impact of interest rate changes on outstanding variable-rate debt, the Company entered into forward starting LIBOR-based interest rate swaps with notional values totaling $50,000. The swaps will become effective in February 2017 at which point it will effectively convert a portion of the debt from variable to fixed-rate borrowings during the term of the swap contract. The fair value of the interest rate swaps is based on market-observable forward interest rates and represents the estimated amount that the Company would pay to terminate the agreements. As such, the swap agreements have been classified as Level 2 within the fair value hierarchy.

The following assets of the Company were measured at fair value on a recurring basis subject to the disclosure requirements of ASC 820 at December 31, 2015 and December 31, 2014:



		Fair Value Measurements at Reporting Date Using								Fair Value Measurements at Reporting Date Using

		December 31, 2015		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		December 31, 2014		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)

COMMITMENTS AND CONTINGENT LIABILITIES

Note 19.

Commitments and Contingent Liabilities

The Company is subject to product warranty claims that arise in the ordinary course of its business. For certain manufactured products, the Company maintains a product warranty accrual that is adjusted on a monthly basis as a percentage of cost of sales. This product warranty accrual is periodically adjusted based on the identification or resolution of known individual product warranty claims.

The following table sets forth the Company’s product warranty accrual:



		Warranty Liability
Balance at December 31, 2014	$	11,500
Additions to warranty liability		1,794
Warranty liability utilized		(4,650)
Acquisitions		111
Balance at December 31, 2015	$	8,755

Included within the above table are concrete tie warranty reserves of approximately $7,544 and $10,331, respectively, at December 31, 2015 and 2014. For the periods ended December 31, 2015, 2014, and 2013, the Company recorded approximately $972, $9,854 and $612, respectively, in pre-tax concrete tie warranty charges within “Cost of Goods Sold” in the Company’s Rail Products and Services segment primarily related to concrete ties manufactured at the Company’s former Grand Island, NE facility.

UPRR Warranty Claims

On July 12, 2011, UPRR notified (the “UPRR Notice”) the Company and its subsidiary, CXT Incorporated (“CXT”), of a warranty claim under CXT's 2005 supply contract relating to the sale of pre-stressed concrete railroad ties to UPRR. UPRR asserted that a significant percentage of concrete ties manufactured in 2006 through 2011 at CXT's Grand Island, NE facility failed to meet contract specifications, had workmanship defects and were cracking and failing prematurely. Of the 3.0 million ties manufactured between 1998 and 2011 from the Grand Island, NE facility, approximately 1.6 million ties were sold during the period UPRR had claimed nonconformance. The 2005 contract called for each concrete tie which failed to conform to the specifications or had a material defect in workmanship to be replaced with 1.5 new concrete ties, provided, that, within five years of the sale of a concrete tie, UPRR notified CXT of such failure to conform or such defect in workmanship. The UPRR Notice did not specify how many ties manufactured during this period were defective nor the exact nature of the alleged workmanship defect.

Following the UPRR Notice, the Company worked with material scientists and pre-stressed concrete experts to test a representative sample of Grand Island, NE concrete ties and assess warranty claims for certain concrete ties made in its Grand Island, NE facility between 1998 and 2011. The Company discontinued manufacturing operations in Grand Island, NE in early 2011.

2012

During 2012, the Company completed sufficient testing and analysis to further understand this matter. Based upon testing results and expert analysis, the Company believed it discovered conditions, which largely related to the 2006 to 2007 manufacturing period, that can shorten the life of the concrete ties produced during this period. During the fourth quarter of 2012 and first quarter of 2013, the Company reached agreement with UPRR on several matters including a process for the Company and UPRR to work together to identify, prioritize, and replace defective ties that meet the criteria for replacement. This process applies to the ties the Company shipped to UPRR from its Grand Island, NE facility from 1998 to 2011. During most of this period the Company’s warranty policy for UPRR carried a 5 year warranty with a 1.5:1 replacement ratio for any defective ties. In order to accommodate UPRR and other customer concerns, the Company also reverted to a previously used warranty policy providing a 15-year warranty with a 1:1 replacement ratio. This change provided an additional 10 years of warranty protection. In the amended 2005 supply agreement, the Company and UPRR also extended the supply of Tucson ties by five years and agreed on a cash payment of $12,000 to UPRR as compensation for concrete ties already replaced by UPRR during the investigation period.

During 2012, as a result of the testing that the Company conducted on concrete ties manufactured at its former Grand Island, NE facility and the developments related to UPRR and other customer matters, the Company recorded pre-tax warranty charges of $22,000 in “Cost of Goods Sold” within its Rail Products and Services segment based on the Company’s estimate of the number of defective concrete ties that will ultimately require replacement during the applicable warranty periods.

2013

Throughout 2013, at UPRR’s request and under the terms of the amended 2005 supply agreement, the Company provided warranty replacement concrete ties for use across certain UPRR subdivisions. The Company attempted to reconcile the quantity of warranty claims for ties replaced and obtain supporting detail for the ties removed. The Company believes that UPRR did not replace concrete ties in accordance with the amended agreement and has not furnished adequate documentation throughout the replacement process in these subdivisions to support its full warranty claim. Based on the information received by the Company to date, the Company believes that a significant number of ties which UPRR replaced in these subdivisions did not meet the criteria to be covered as warranty replacement ties under the amended 2005 supply agreement. The disagreement related to the 2013 warranty replacement activity includes approximately 170,000 ties where the Company provided detailed documentation supporting our position with reason codes that detail why these ties are not eligible for a warranty claim.

In late November 2013, the Company received notice from UPRR asserting a material breach of the amended 2005 supply agreement. UPRR’s notice asserted that the failure to honor its claims for warranty ties in these subdivisions was a material breach. Following receipt of this notice, the Company provided information to UPRR to refute UPRR’s claim of breach and included the reconciliation of warranty claims supported by substantial findings from the Company’s track observation team, all within the 90 day cure period. The Company also proposed further discussions to reach agreement on reconciliation for 2013 replacement activities and future replacement activities and a recommended process that will ensure future replacement activities are done with appropriate documentation and per the terms of the amended 2005 supply agreement.

2014

During the first quarter of 2014, the Company further responded within the 90 day cure period to UPRR’s claim and presented a reconciliation for the subdivisions at issue. This proposed reconciliation was based on empirical data and visual observation from Company employees that were present during the replacement process for a substantial majority of the concrete ties replaced. The Company spent considerable time documenting facts related to concrete tie condition and track condition to assess whether the ties replaced met the criteria to be eligible for replacement under the terms of the amended 2005 supply agreement.

During 2014, the Company increased its accrual by an additional $8,766 based on revised estimates of ties to be replaced based upon scientific testing and other analysis, adjusted for ties already provided to UPRR. The Company continued to work with UPRR to identify, replace, and reconcile defective ties related to the warranty claim in accordance with the amended 2005 supply agreement. The Company and UPRR met during the third quarter of 2014 to evaluate each other’s position in an effort to work towards agreement on the unreconciled 2013 and 2014 replacement activity as well as the standards and practices to be implemented for future replacement activity and warranty tie replacement.

In November and December of 2014, the Company received additional notices from UPRR asserting that ties manufactured in 2000 were defective and again asserting material breaches of the amended 2005 supply agreement relating to warranty tie replacements as well as certain new ties provided to UPRR being out of specification.

As of December 31, 2014, the Company and UPRR had not been able to reconcile the disagreement related to the 2013 and 2014 warranty replacement activity. The disagreement relating to the 2014 warranty replacement activity includes approximately 90,100 ties that the Company believes are not warranty-eligible.

2015

On January 23, 2015, UPRR filed a Complaint and Demand for Jury Trial in the District Court for Douglas County, NE against the Company and its subsidiary, CXT, asserting, among other matters, that the Company breached its express warranty, breached an implied covenant of good faith and fair dealing, anticipatorily repudiated its warranty obligations, and that UPRR’s exclusive and limited remedy provisions in the supply agreement have failed of their essential purpose which entitles UPRR to recover all incidental and consequential damages. The Complaint seeks to cancel all duties of UPRR under the contract, to adjudge the Company as having no remaining rights under the contracts, and to recover damages in an amount to be determined at trial for the value of unfulfilled warranty replacement ties and ties likely to become warranty eligible, for costs of cover for replacement ties, and for various incidental and consequential damages. The amended 2005 supply agreement provides that UPRR’s exclusive remedy is to receive a replacement tie that meets the contract specifications for each tie that failed to meet the contract specifications or otherwise contained a material defect provided that the Company receives written notice of such failure or defect within 15 years after that tie was produced. The amended 2005 supply agreement provides that the Company’s warranty does not apply to ties that (a) have been repaired or altered without the Company’s written consent in such a way as to affect the stability or reliability thereof, (b) have been subject to misuse, negligence, or accident, or (c) have been improperly maintained or used contrary to the specifications for which such ties were produced. The amended 2005 supply agreement also continues to provide that the Company’s warranty is in lieu of all other express or implied warranties and that neither party shall be subject to or liable for any incidental or consequential damages to the other party. The dispute is largely based on (1) claims submitted that the Company believes are for ties claimed for warranty replacement inaccurately rated that are not the responsibility of the Company and claims that do not meet the criteria of a warranty replacement and (2) UPRR’s assertion, which the Company vigorously disputes, that UPRR in future years will be entitled to warranty replacement ties for virtually all of the Grand Island ties. Many thousands of Grand Island ties have been performing in track for over ten years. In addition, a significant amount of Grand Island ties were rated by both parties in the excellent category of the rating system.

In June 2015, UPRR delivered an additional notice alleging defects in ties produced in the Company’s Tucson and Spokane locations and other claimed material breaches which the Company contends are unfounded. The Company again responded to UPRR that it was not in material breach of the amended 2005 supply agreement relating to warranty tie replacements and that new ties being manufactured complied with the specifications provided by UPRR.

On June 16 and 17, 2015, UPRR issued formal notice of the termination of the concrete tie supply agreement as well as the termination of the lease agreement at the Tucson, AZ production facility and rejection and revocation of its prior acceptance of certain ties manufactured at the Company’s Spokane, WA production facility. Since that time, UPRR has discontinued submitting purchase orders to the Company for shipment of warranty replacement ties.

On May 29, 2015, the Company and CXT filed an Answer, Affirmative Defenses and Counterclaims in response to the Complaint, denying liability to UPRR. As a result of UPRR's subsequent June 16-17, 2015 actions and certain related conduct, the Company on October 5, 2015 amended the pending Answer, Affirmative Defenses and Counterclaims to add, among other things, assertions that UPRR's conduct in question was wrongful and unjustified and constituted additional grounds for the affirmative defenses to UPRR’s claims and also for the Company’s counterclaims. By Scheduling Order dated September 3, 2015, a December 30, 2016 deadline for the completion of fact discovery has been established and trial may proceed at some future date after March 3, 2017, although no trial date has been set. The parties are currently conducting discovery.

The Company continues to engage in discussions in an effort to resolve this matter. However, we cannot predict that such discussions will be successful, or that the results of the litigation with UPRR, or any settlement or judgment amounts will be within the range of our estimated accruals for loss contingencies. Future potential costs pertaining to UPRR’s claims and the outcome of the UPRR litigation could result in a material adverse effect on our results of operations, financial condition, and cash flows.

Other Legal Matters

The Company is also subject to other legal proceedings and claims that arise in the ordinary course of its business. In the opinion of management, the amount of ultimate liability with respect to these actions will not materially affect the financial condition or liquidity of the Company. The resolution, in any reporting period, of one or more of these matters could have a material effect on the Company’s results of operations for that period.

Environmental Matters

The Company is subject to national, state, foreign, and/or local laws and regulations relating to the protection of the environment. The Company is monitoring its potential environmental exposure related to current and former facilities. The Company’s efforts to comply with environmental regulations may have an adverse effect on its future earnings. In the opinion of management, compliance with the present environmental protection laws will not have a material adverse effect on the financial condition, results of operations, cash flows, competitive position, or capital expenditures of the Company.

Summary of Significant Accounting Policies (Policies)	12 Months Ended
Summary of Significant Accounting Policies (Policies)	Dec. 31, 2015
Summary Of Significant Accounting Policies [Abstract]
Basis of financial statement presentation [Policy Text Block]	Basis of financial statement presentation The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries, ventures, and partnerships in which a controlling interest is held. Inter-company transactions and accounts have been eliminated. The Company utilizes the equity method of accounting for companies where its ownership is less than or equal to 50% and significant influence exists.
Cash and cash equivalents [Policy Text Block]	Cash and cash equivalents The Company considers cash and other instruments with maturities of three months or less, when purchased, to be cash and cash equivalents. The Company invests available funds in a manner to maximize returns, preserve investment principal, and maintain liquidity while seeking the highest yield available. Cash and cash equivalents held in non-domestic accounts was approximately $29,700 and $49,233 at December 31, 2015 and 2014, respectively. Included in non-domestic cash equivalents are investments in bank term deposits of approximately $1,939 and $25 at December 31, 2015 and 2014, respectively. The carrying amounts approximated fair value because of the short maturity of the instruments.
Inventories [Policy Text Block]	Inventories Certain inventories are valued at the lower of the last-in, first-out (“LIFO”) cost or market. Approximately 43% in 2015 and 44% in 2014, of the Company’s inventory is valued at average cost or market, whichever is lower. Slow-moving inventory is reviewed and adjusted regularly, based upon product knowledge, physical inventory observation, and the age of the inventory.
Property, plant and equipment [Policy Text Block]	Property, plant, and equipment Depreciation and amortization are provided on a straight-line basis over the estimated useful lives of 5 to 40 years for buildings and 2 to 10 years for machinery and equipment. Leasehold improvements are amortized over 3 to 13 years, which represent the lives of the respective leases or the lives of the improvements, whichever is shorter. Depreciation expense is recorded within “cost of sales” and “selling and administrative” expenses based upon the particular asset’s use. The Company reviews a long-lived asset for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. There were no material asset impairments recorded for the years ended December 31, 2015, 2014, or 2013. Maintenance, repairs, and minor renewals are charged to operations as incurred. Major renewals and betterments that substantially extend the useful life of the property are capitalized at cost. Upon sale or other disposition of assets, the costs and related accumulated depreciation and amortization are removed from the accounts and the resulting gain or loss, if any, is reflected in income.
Allowance for doubtful accounts [Policy Text Block]	Allowance for doubtful accounts The allowance for doubtful accounts is recorded to reflect the ultimate realization of the Company’s accounts receivable and includes assessment of the probability of collection and the credit-worthiness of certain customers. Reserves for uncollectible accounts are recorded as part of selling and administrative expenses on the Consolidated Statements of Operations. The Company records a monthly provision for accounts receivable that are considered to be uncollectible. In order to calculate the appropriate monthly provision, the Company reviews its accounts receivable aging and calculates an allowance through application of historic reserve factors to overdue receivables. This calculation is supplemented by specific account reviews performed by the Company’s credit department. As necessary, the application of the Company’s allowance rates to specific customers is reviewed and adjusted to more accurately reflect the credit risk inherent within that customer relationship.
Investments [Policy Text Block]	Investments Investments in companies in which the Company has the ability to exert significant influence, but not control, over operating and financial policies (generally 20% to 50% ownership) are accounted for using the equity method. Under the equity method, investments are initially recorded at cost and adjusted for dividends and undistributed earnings and losses. The equity method of accounting requires a company to recognize a loss in the value of an equity method investment that is other than a temporary decline.
Goodwill and other intangible assets [Policy Text Block]	Goodwill and other intangible assets Goodwill is tested annually for impairment or more often if there are indicators of impairment. The goodwill impairment test involves comparing the fair value of a reporting unit to its carrying value, including goodwill. If the carrying amount of the reporting unit exceeds its fair value, a second step is required to measure the goodwill impairment loss. This step compares the implied fair value of the reporting unit’s goodwill to the carrying amount of that goodwill. If the carrying amount of the goodwill exceeds the implied fair value of the goodwill, an impairment loss equal to the excess is recorded as a component of operations. The Company performs its annual impairment tests as of October 1st. During 2015, the Company identified certain triggering events that indicated an interim impairment test was required. As a result of the interim assessment as of September 1, 2015, the Company recorded impairment charges of $80,337 ($63,887 net of taxes) during 2015 related to the acquisitions of IOS and Chemtec. The measurement of goodwill impairment is a Level 3 fair value measurement, as the primary assumptions, including estimates of future revenue growth, gross margin, and EBITDA margin, are not market observable and require management to make judgements regarding future outcomes. Additional information concerning the impairments is set forth in Note 4 to the financial statements. No additional charges were recorded as a result of the 2015 annual impairment test. No goodwill impairment was recognized during 2014 or 2013. The Company has no indefinite-lived intangible assets. The Company reviews a long-lived intangible asset for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. All intangible assets are amortized over their useful lives ranging from 5 to 25 years, with a total weighted average amortization period of approximately 14 years, at December 31, 2015. See Note 4 for additional information including regarding the Company’s other intangible assets.
Environmental remediation and compliance [Policy Text Block]	Environmental remediation and compliance Environmental remediation costs are accrued when the liability is probable and costs are estimable. Environmental compliance costs, which principally include the disposal of waste generated by routine operations, are expensed as incurred. Capitalized environmental costs, when appropriate, are depreciated over their useful life. Reserves are not reduced by potential claims for recovery. Claims for recovery are recognized as agreements are reached with third parties or as amounts are received. Reserves are periodically reviewed throughout the year and adjusted to reflect current remediation progress, prospective estimates of required activity, and other factors that may be relevant, including changes in technology or regulations. See Note 19, “Commitments and Contingent Liabilities,” for additional information regarding the Company’s outstanding environmental and litigation reserves.
Earnings per share [Policy Text Block]	Earnings per share Basic earnings per share is calculated by dividing net income by the weighted average of common shares outstanding during the year. Diluted earnings per share is calculated by using the weighted average of common shares outstanding adjusted to include the potentially dilutive effect of outstanding stock options and restricted stock utilizing the treasury stock method.
Revenue recognition	Revenue recognition The Company’s revenues are comprised of product and service sales as well as products and services provided under long-term contracts. For product and service sales, the Company recognizes revenue when the following criteria have been satisfied; persuasive evidence of a sales arrangement exists, product delivery and transfer of title to the customer has occurred or services have been rendered, the price is fixed or determinable, and collectability is reasonably assured. Generally, product title passes to the customer upon shipment. In limited cases, title does not transfer and revenue is not recognized until the customer has received the products at its physical location. Revenue is recorded net of returns, allowances, customer discounts, and incentives. Sales taxes collected from customers and remitted to governmental authorities are accounted for on a net (excluded from revenues) basis. Shipping and handling costs are included in cost of goods sold.
Revenue recognition - Percentage of Completion Method [Policy Text Block]	Revenues for products and services under long-term contracts are recognized using the percentage-of-completion method. Sales and gross profit are recognized as work is performed based upon the proportion of actual costs incurred to estimated total project costs. Sales and gross profit are adjusted prospectively for revisions in estimated total project costs and contract values. For certain products and services, the percentage of completion is based upon actual labor costs as a percentage of estimated total labor costs. At the time a loss contract becomes known, the entire amount of the estimated loss is recognized in the Consolidated Statement of Operations. Revenue recognition involves judgments, including assessments of expected returns, the likelihood of nonpayment, and estimates of expected costs and profits on long-term contracts. In determining when to recognize revenue, we analyze various factors, including the specifics of the transaction, historical experience, creditworthiness of the customer, and current market and economic conditions. Changes in judgments on these factors could impact the timing and amount of revenue recognized with a resulting impact on the timing and amount of associated income. Costs in excess of billings are classified as work-in-process inventory. Projects with billings in excess of costs are recorded within deferred revenue.
Revenue Recognition, Deferred Revenue [Policy Text Block]	Deferred revenue Deferred revenue consists of customer payments received for which the revenue recognition criteria have not yet been met as well as billings in excess of costs on percentage of completion projects. Advanced payments from customers typically relate to contracts with respect to which the Company has significantly fulfilled its obligations, but due to the Company’s continuing involvement with the project, revenue is precluded from being recognized until title, ownership, and risk of loss have passed to the customer.
Fair value of financial instruments [Policy Text Block]	Fair value of financial instruments The Company’s financial instruments consist of cash equivalents, accounts receivable, accounts payable, interest rate swap agreements, and debt. The carrying amounts of the Company’s financial instruments at December 31, 2015 and 2014 approximate fair value. See Note 18, “Fair Value Measurements,” for additional information.
Stock-based compensation [Policy Text Block]	Stock-based compensation The Company applies the provisions of FASB ASC 718, “Compensation – Stock Compensation,” to account for the Company’s share-based compensation. Under the guidance, share-based compensation cost is measured at the grant date based on the calculated fair value of the award. The expense is recognized over the employees’ requisite service period, generally the vesting period of the award. See Note 15, “Stare-based Compensation,” for additional information.
Product Warranty [Policy Text Block]	Product warranty The Company maintains a current warranty liability for the repair or replacement of defective products. For certain manufactured products, an accrual is made on a monthly basis as a percentage of cost of sales based upon historical experience. For long-lived construction products, a warranty is established when the claim is known and quantifiable. The product warranty accrual is periodically adjusted based on the identification or resolution of known individual product warranty claims or due to changes in the Company’s historical warranty experience. At December 31, 2015 and 2014, the product warranty reserve was $8,755 and $11,500, respectively. See Note 19, “Commitments and Contingencies” for additional information regarding the product warranty.
Income Taxes [Policy Text Block]	Income taxes Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of assets and liabilities and their respective tax bases. Deferred taxes are measured using enacted tax laws and rates expected to be in effect when such differences are recovered or settled. The effect of a change in tax rates on deferred taxes is recognized in income in the period that includes the enactment date of the change. The Company makes judgments regarding the recognition of deferred tax assets and the future realization of these assets. As prescribed by Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 740 “Income Taxes” and applicable guidance, valuation allowances must be provided for those deferred tax assets for which it is more likely than not (a likelihood more than 50%) that some portion or all of the deferred tax assets will not be realized. The guidance requires the Company to evaluate positive and negative evidence regarding the recoverability of deferred tax assets. Determination of whether the positive evidence outweighs the negative evidence and quantification of the valuation allowance requires the Company to make estimates and judgments of future financial results. The Company evaluates all tax positions taken on its federal, state, and foreign tax filings to determine if the position is more likely than not to be sustained upon examination. For positions that meet the more likely than not to be sustained criteria, the largest amount of benefit to be realized upon ultimate settlement is determined on a cumulative probability basis. A previously recognized tax position is derecognized when it is subsequently determined that a tax position no longer meets the more likely than not threshold to be sustained. The evaluation of the sustainability of a tax position and the expected tax benefit is based on judgment, historical experience, and various other assumptions. Actual results could differ from those estimates upon subsequent resolution of identified matters. The Company accrues interest and penalties related to unrecognized tax benefits in its provision for income taxes.
Foreign Currency Translation [Policy Text Block]	Foreign currency translation The assets and liabilities of our foreign subsidiaries are measured using the local currency as the functional currency and are translated into U.S. dollars at exchange rates as of the balance sheet date. Income statement amounts are translated at the weighted-average rates of exchange during the year. The translation adjustment is accumulated as a separate component of accumulated other comprehensive income (loss). Foreign currency transaction gains and losses are included in determining net income. Included in net income for the years ended December 31, 2015, 2014, and 2013 were foreign currency transaction gains of approximately $1,616, $422, and $433, respectively.
Research and development [Policy Text Block]	Research and development The Company expenses research and development costs as costs are incurred. For the years ended December 31, 2015, 2014, and 2013, research and development expenses were $3,937, $3,096, and $3,154, respectively, and were principally related to the Company’s friction management and railroad monitoring system products.
Use of estimates [Policy Text Block]	Use of estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.
Reclassifications [Policy Text Block]	Reclassifications Certain accounts in the prior year consolidated financial statements have been reclassified for comparative purposes principally to conform to the presentation in the current year period. These reclassifications include separately presenting sales of services and cost of services sold to reflect the Company’s increased service offerings attributable to the recent acquisitions disclosed in Note 3 and a change in GAAP, as further described below.
Recently issued or adopted accounting guidance [Policy Text Block]	Recently issued accounting guidance In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2014-09, “Revenue from Contracts with Customers (Topic 606)” (“ASU 2014-09”), which supersedes the revenue recognition requirements in Accounting Standards Codification 605, “Revenue Recognition.” ASU 2014-09 is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. It also requires additional disclosure about the nature, amount, timing, and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. ASU 2014-09 is effective for fiscal years beginning after December 15, 2017, including interim periods within that reporting period. The Company is currently evaluating its implementation approach and assessing the impact of ASU 2014-09 on our financial position and results of operations. In July 2015, the FASB issued ASU No. 2015-11, “Inventory (Topic 330): Simplifying the Measurement of Inventory.” The pronouncement was issued to simplify the measurement of inventory and changes the measurement from lower of cost or market to lower of cost and net realizable value. This pronouncement is effective for reporting periods beginning after December 15, 2016. The adoption of ASU 2015-11 is not expected to have a significant impact on our financial position or results of operations. Recently adopted accounting guidance In April 2015, the FASB issued ASU No. 2015-03, “Interest-Imputation of Interest (Topic 835-30): Simplifying the Presentation of Debt Issuance Costs”, which requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. Debt issuance costs related to line of credit arrangements may continue to be reflected as an asset. The recognition and measurement guidance of debt issuance costs are not affected by the amendments in this update. The standard is effective for financial statements issued for annual periods beginning after December 15, 2015, and interim periods within those annual periods. The Company early adopted the new guidance in the fourth quarter of 2015 and there was no impact to the consolidated financial statements from the adoption of this guidance. In September 2015, the FASB issued ASU No. 2015-16 “Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments” (“ASU 2015-16”). ASU 2015-16 requires that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. Prior to the issuance of the standard, entities were required to retrospectively apply adjustments made to provisional amounts recognized in a business combination. ASU 2015-16 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2015, and early adoption is permitted. Accordingly, the standard is effective for the Company on January 1, 2016. The Company early adopted the new guidance in the fourth quarter of 2015 and there was no impact to the consolidated financial statements from the adoption of this guidance. In November 2015, the FASB issued ASU No. 2015-17, “Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes” ("ASU 2015-17"). This new guidance requires businesses to classify deferred tax liabilities and assets on their balance sheets as noncurrent. Under existing accounting, a business must separate deferred income tax liabilities and assets into current and noncurrent. ASU 2015-17 was issued as a way to simplify the way businesses classify deferred tax liabilities and assets on their balance sheets. Public companies must apply ASU 2015-17 to fiscal years beginning after December 15, 2016. Companies must follow the requirements for interim periods within those fiscal years, but early adoption at the beginning of an interim or annual period is allowed for all entities. The Company adopted this guidance during the fourth quarter of 2015 on a retrospective basis, which resulted in the reclassification of $3,497 current deferred tax assets and $77 current deferred tax liabilities to non-current as of December 31, 2014.

Segment Reporting, Factors Used to Identify Entity's Reportable Segments	The Company is a leading manufacturer, fabricator, and distributor of products and services for rail, construction, energy, and utility markets. The Company is organized and evaluated by product group, which is the basis for identifying reportable segments. Each segment represents a revenue-producing component of the Company for which separate financial information is produced internally that is subject to evaluation by the Company's chief operating decision maker in deciding how to allocate resources. Each segment is evaluated based upon their segment profit contribution to the Company's consolidated results. As a result of recently completed acquisitions, during the first quarter of 2015, the Company renamed the Rail Products and Tubular Products business segments to be Rail Products and Services and Tubular and Energy Services, respectively. The name changes principally reflect the additional businesses conducted by those segments as a result of acquisitions that have enhanced our product and service offerings within the rail and energy markets. Excluding the addition of current year acquisitions, there were no changes to the divisions that have been aggregated within the segments nor were there changes to the historical reportable segment results.The Company markets its products directly in all major industrial areas of the United States, Canada, and Europe, primarily through an internal sales force.The Company's Rail Products and Services segment provides a full line of new and used rail, trackwork, and accessories to railroads, mines, and other customers in the rail industry. The Rail segment also designs and produces insulated rail joints, power rail, track fasteners, concrete railroad ties, coverboards, and special accessories for mass transit and other rail systems. In addition, the Rail Products and Services segment engineers, manufactures, and assembles friction management products and railway wayside data collection and management systems. The Company's Construction Products segment sells and rents steel sheet piling, H-bearing pile, and other piling products for foundation and earth retention requirements. The Company's Fabricated Products division sells bridge decking, bridge railing, structural steel fabrications, expansion joints, bridge forms, and other products for highway construction and repair. The concrete products businesses produce precast concrete buildings and a variety of specialty precast concrete products.The Company's Tubular and Energy Services segment provides pipe coatings for natural gas pipelines and utilities, upstream test and inspection services, precision measurement systems for the oil and gas market, and produces threaded pipe products for the oil and gas markets as well as industrial water well and irrigation markets.
Segment Reporting, Measurement for Transactions Between Reportable Segments	The following table illustrates net sales, profit (loss), assets, depreciation/amortization, and expenditures for long-lived assets of the Company by segment for the years ended or at December 31, 2015, 2014, and 2013. Segment profit is the earnings from operations before income taxes and includes internal cost of capital charges for net assets used in the segment at a rate of generally 1% per month excluding recently acquired businesses. The internal cost of capital charges are eliminated during the consolidation process. The accounting policies of the reportable segments are the same as those described in the summary of significant accounting policies except that the Company accounts for inventory on a First-In, First-Out ("FIFO") basis at the segment level compared to a Last-In, First-Out ("LIFO") basis at the consolidated level

Variable Interest Entity, Methodology for Determining Whether Entity is Primary Beneficiary

Under applicable guidance for variable interest entities in ASC 810, "Consolidation," the Company determined that the LB Pipe JV is a variable interest entity. The Company concluded that it is not the primary beneficiary of the variable interest entity, as the Company does not have a controlling financial interest and does not have the power to direct the activities that most significantly impact the economic performance of the LB Pipe JV. Accordingly, the Company concluded that the equity method of accounting remains appropriate

[1]	On November 23, 2015, the Company acquired the remaining 75% of shares of Tew Plus resulting in a gain of $580, which is recorded within other income as of December 31, 2015. The gain is included in equity loss (income) and remeasurement gain within the Consolidated Statements of Cash Flows.
