Organization Consolidation And Presentation Of Financial Statements [Abstract]
Basis of Reporting for Consolidated Financial Statements	1. Basis of Reporting for Consolidated Financial Statements The accompanying unaudited condensed consolidated financial statements of CECO Environmental Corp. and its subsidiaries (the “Company”, “we”, “us”, or “our”) have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Certain information and footnote disclosures normally included in annual financial statements have been condensed or omitted pursuant to those rules and regulations. In the opinion of management, the accompanying unaudited condensed consolidated financial statements of the Company contain all adjustments (consisting only of normal recurring adjustments) necessary to present fairly the financial position as of June 30, 2016 and the results of operations and cash flows for the three-month and six-month periods ended June 30, 2016 and 2015. The results of operations for the three-month and six-month periods ended June 30, 2016 are not necessarily indicative of the results to be expected for the full year. The balance sheet as of December 31, 2015 has been derived from the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015 as filed with the SEC. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. These financial statements and accompanying notes should be read in conjunction with the audited financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015 filed with the SEC. Unless otherwise indicated, all balances within tables are in thousands, except per share amounts. On September 3, 2015, the Company completed the acquisition of PMFG, Inc. (“PMFG”). The results of its operations have been consolidated with our results following the acquisition date. For a more complete discussion of the transaction, refer to Note 17. The Company’s consolidated financial statements include the accounts of all wholly-owned and majority-owned subsidiaries for all periods presented. All significant inter-company accounts and transactions have been eliminated in consolidation. The Company is the majority owner of Peerless Propulsys China Holdings LLC (“Peerless Propulsys”). The Company’s 60% equity investment in Peerless Propulsys entitles it to 80% of the earnings. Peerless Propulsys is the sole owner of Peerless China Manufacturing Co. Ltd. (“PCMC”). The noncontrolling interest of Peerless Propulsys is reported as a separate component on the Condensed Consolidated Balance Sheets. On July 12, 2016, the Company entered into an agreement with the noncontrolling owner of Peerless Propulsys and issued a promissory note in the amount of $5.3 million due on July 11, 2019 to the noncontrolling owner in exchange for 100% ownership in the equity and earnings of Peerless Propulsys. The impact of this agreement will be recorded in the third quarter of 2016.

Accounting Changes And Error Corrections [Abstract]
New Financial Accounting Pronouncements	2. New Financial Accounting Pronouncements In May 2016, the Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) These pronouncements have the same effective date as the new revenue standard, which is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. The Company is currently evaluating the impact of the adoption of these standards on the Company’s consolidated financial statements and has not yet determined the method of adoption. In March 2016, the FASB issued ASU 2016-09, “Compensation—Stock Compensation: Improvements to Employee Share-Based Payment Accounting .” In March 2016, the FASB issued ASU 2016-05, “Derivatives and Hedging: Effect of Derivative Contract Novations on Existing Hedge Accounting Relationships.” ASU 2016-09 is effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. The Company is currently evaluating the potential impact of the adoption of this standard on the Company’s consolidated financial statements In February 2016, the FASB issued ASU 2016-02, “Leases.” ASU 2016-02 establishes a right-of-use (“ROU”) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. The Company is currently evaluating the potential impact of the adoption of ASU 2016-02 on the Company’s consolidated financial statements . In July 2015, the FASB issued ASU 2015-11, “Simplifying the Measurement of Inventory.” ASU 2015-11 requires inventory within the scope of the ASU (e.g., first-in, first-out (“FIFO”) or average cost) to be measured using the lower of cost and net realizable value. Inventory excluded from the scope of the ASU (i.e., last-in, first-out (“LIFO”) or the retail inventory method) will continue to be measured at the lower of cost or market. The ASU also amends some of the other guidance in Topic 330, “Inventory,” to more clearly articulate the requirements for the measurement and disclosure of inventory. However, those amendments are not intended to result in any changes to current practice. ASU 2015-11 is effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. The adoption of this standard is not expected to have a significant impact on the Company’s consolidated financial statements . In May 2014, the FASB issued ASU 2014-09, “Revenue From Contracts With Customers.” ASU 2014-09 supersedes nearly all existing revenue recognition principles under GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration an entity expects to be entitled to for those goods or services using a defined five step process. More judgment and estimates may be required to achieve this principle than under existing GAAP. ASU 2014-09 is effective for annual periods beginning after December 15, 2017, including interim periods therein, using either of the following transition methods: (i) a full retrospective approach reflecting the application of the standard in each prior reporting period with the option to elect certain practical expedients or (ii) a retrospective approach with the cumulative effect upon initial adoption recognized at the date of adoption, which includes additional footnote disclosures. The Company is currently evaluating the impact of the adoption of ASU 2014-09 on the Company’s consolidated financial statements and has not yet determined the method of adoption . The Company’s current revenue recognition policies are generally consistent with the new revenue recognition standards set forth in ASU 2014-09. Potential adjustments to input measures are not expected to be pervasive to the majority of the Company’s contracts. While no significant impact is expected upon adoption of the new guidance, the Company will not be able to make that determination until the time of adoption based upon outstanding contracts at that time.

Costs and Estimated Earnings on Uncompleted Contracts	4. Costs and Estimated Earnings on Uncompleted Contracts Revenues from contracts are primarily recognized on the percentage of completion method, measured by the percentage of contract costs incurred to date compared with estimated total contract costs for each contract. This method is used because management considers contract costs to be the best available measure of progress on these contracts. For contracts where the duration is short, total contract revenue is insignificant, or reasonably dependable estimates cannot be made, revenues are recognized on a completed contract basis, when risk and title passes to the customer, which is generally upon shipment of product. During the second quarter, the Company’s Zhongli division within the Energy segment has recognized revenue on a percentage of completion method compared to the completed contracts method that was utilized in previous quarters. This change was made after determining that the Company has designed and implemented appropriate controls to track project costs and estimates to complete. During the three months ended June 30, 2016, this division recognized $8.2 million in percentage of completion revenue. Our contracts have various lengths to completion ranging from a few days to several months. We anticipate that a majority of our current contracts will be completed within the next twelve months.

Changes to job performance, job conditions, and estimated profitability may result in revisions to contract revenue and costs and are recognized in the period in which the revisions are made. A provision of $0.1 million for estimated losses on uncompleted contracts was recognized at June 30, 2016. No provision for estimated losses on uncompleted contracts was required at December 31, 2015.

The Company completes an annual (or more often if circumstances require) impairment assessment of its goodwill and indefinite life intangible assets as of October 1. For 2015, the first step of the two-step goodwill impairment test as described in FASB ASC 350-20-35 was performed for all reporting units, except for the recently acquired PMFG reporting unit, as there were no events or changes in operations since the acquisition date that would indicate possible impairment Under the first step, the Company bases its measurement of the fair value of a reporting unit using a weighting of the income method and the market method on a 50/50 basis. In prior years, the Company used the income method. The income method is based on a discounted future cash flow approach that uses the significant assumptions of projected revenue, projected operational profit, terminal growth rates, and the cost of capital. Projected revenue, projected operational profit and terminal growth rates were determined to be significant assumptions because they are three primary drivers of the projected cash flows in the discounted future cash flow approach. Cost of capital was also determined to be a significant assumption as it is the discount rate used to calculate the current fair value of those projected cash flows. The market method is based on financial multiples of comparable companies and applies a control premium. Significant estimates in the market approach include identifying similar companies with comparable business factors such as size, growth, profitability, risk and return on investment and assessing comparable revenue and operating income multiples in estimating the fair value of a reporting unit. Based on the step 1 analysis, the resultant estimated fair value of the reporting units exceeded their carrying value as of October 1, 2015 and For one of the reporting units tested under the step 1 analysis in 2015, which carried goodwill of $77.9 million, the excess of fair value over their carrying value was only 8%. This reporting unit was acquired in the second half of fiscal 2013, and therefore the Company did not expect the fair value to be significantly in excess of the carrying value. Furthermore, there were no fundamental changes in the business or market that would indicate a significant decline in the fair value since the acquisition date. Management’s projections used to estimate the undiscounted cash flows included increasing sales volumes and operational improvements designed to reduce costs. Changes in any of the significant assumptions used, including if the Company does not successfully achieve its 2016 operating plan, can materially affect the expected cash flows, and such impacts can result in the requirement to proceed to a step 2 test and potentially a material non-cash impairment charge could result. Therefore, the key assumptions most susceptible to change are projected revenue and projected operational profit. We determined that with other assumptions held constant under our weighted income and market method for measuring fair value, a decrease in projected revenue growth rates of approximately 110 basis points or a decrease in projected EBITDA rates of approximately 390 basis points would result in fair value of the reporting unit being equal to its carrying value, which would require us to perform a step 2 test for this reporting unit. During 2015, the Company also performed a step 1 analysis for all reporting units with indefinite life intangible assets. The Company based its measurement of the fair value of the indefinite life intangible assets utilizing the relief from royalty method. The significant assumptions used under the relief from royalty method are projected revenue, royalty rates, terminal growth rates, and the cost of capital. Projected revenue, royalty rates and terminal growth rates were determined to be significant assumptions because they are three primary drivers of the projected royalty cash flows in the relief from royalty method. Cost of capital was also determined to be a significant assumption as it is the discount rate used to calculate the current fair value of those projected royalty cash flows. Changes in any of the significant assumptions used, including if the Company does not successfully achieve its 2016 operating plan, can materially affect the expected cash flows, and such impacts can result in material non-cash impairment charges. Under this approach, the resultant estimated fair value of the indefinite life intangible assets exceeded their carrying value for all but three reporting units as of October 1, 2015. For three of the reporting units, which carried combined indefinite life intangible assets of $10.0 million, our fair value measurement resulted in the aggregate fair value being 33.4% lower than the aggregate carrying value. Accordingly, we recorded an impairment charge of $3.3 million during the three-month period ended December 31, 2015. These three reporting units were acquired in the second half of fiscal 2013. Management’s projections used to estimate the fair values at the date of acquisition primarily included increasing sales volumes; however, the units have experienced lower sales than originally projected. The Company did not identify any triggering events during the three-month and six-month periods ended June 30, 2016 that would require an interim impairment assessment of goodwill or indefinite life intangible assets.

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]
Share-Based Compensation	10. Share-Based Compensation The Company accounts for stock-based compensation in accordance with ASC Topic 718, “Compensation – Stock Compensation,” which requires the Company to recognize compensation expense for stock-based awards, measured at the fair value of the awards at the grant date. The Company recognized expense of $0.6 million and $0.4 million during the three-month periods ended June 30, 2016 and 2015, respectively, and $1.1 million and $0.9 million during the six-month periods ended June 30, 2016 and 2015, respectively. The Company granted no options during the three-month periods ended June 30, 2016 and 2015 and approximately 100,000 options during the six-month periods ended June 30, 2016 and 2015, respectively. The weighted-average fair value of stock options granted during the six months ended June 30, 2016 and 2015 was estimated at $2.07 and $7.15 per option, respectively, using the Black-Scholes option-pricing model based on the following assumptions: Expected Volatility: The Company utilizes a volatility factor based on the Company’s historical stock prices for a period of time equal to the expected term of the stock option utilizing weekly price observations. For the six months ended June 30, 2016 and 2015, the Company utilized a weighted-average volatility factor of 39% and 54%, respectively. Expected Term: For the six months ended June 30, 2016 and 2015, the Company utilized a weighted-average expected term factor of 6.5 years. Risk-Free Interest Rate: The risk-free interest rate factor utilized is based upon the implied yields currently available on U.S. Treasury zero-coupon issues over the expected term of the stock options. For the six months ended June 30, 2016 and 2015, the Company utilized a weighted-average risk-free interest rate factor of 2.1% and 2.0%, respectively. Expected Dividends: The Company utilized a weighted average expected dividend rate of 3.6% and 1.6% to value options granted during the six months ended June 30, 2016 and 2015, respectively. The Company granted approximately 90,000 and 10,000 restricted stock units during the three-month periods ended June 30, 2016 and 2015, respectively, and approximately 100,000 and 10,000 restricted stock units during the six-month periods ended June 30, 2016 and 2015, respectively. The weighted-average fair value of restricted stock units granted during the six months ended June 30, 2016 was estimated at $7.77 per unit using the value of stock in the open market on the date of grant. The fair value of the stock-based awards granted is recorded as compensation expense on a straight-line basis over the vesting periods of the awards adjusted for the Company’s estimate of pre-vesting forfeitures. The pre-vesting forfeiture estimate is based on historical activity and is reviewed periodically and updated as necessary. There is a portion of the outstanding restricted stock units that have both performance and service-based vesting conditions. The Company has determined that the performance condition is likely to be met. As such, the related expense will be recognized over the service period. There were approximately 51,000 options exercised during the six months ended June 30, 2016. The Company received $0.3 million and $0.1 million in cash from employees and directors exercising options during the six months ended June 30, 2016 and 2015, respectively.

Sale-leaseback Transactions	15. Sale-leaseback Transactions Denton Facility On June 2, 2016, the Company entered into an agreement to sell its manufacturing facility in Denton, Texas for gross proceeds of $5.0 million, less costs associated with the transaction of $0.3 million, or net proceeds of $4.7 million. As a part of the transaction, the Company entered into a lease for the property from the purchaser for a period of 13 years. Prior to the consummation of the above transaction, the Company entered into a sublease agreement with a supplier of the Company at this facility for a period of five years. Due to the Company’s continuing involvement through the sublease agreement, the Company has accounted for the sale-leaseback as a financing liability. Payments made by the Company are allocated between interest expense and a reduction to the sale-leaseback financing liability. The weighted-average effective interest rate of the sale-leaseback financing liability was 2.22%. As of June 30, 2016, future payments on the sale-leaseback financing liability are as follows (in thousands): Fiscal Years Payments Remainder of 2016 $ 229 2017 399 2018 407 2019 415 2020 423 2021 431 Thereafter 3,480 Total payments 5,784 Less amount representing interest (784 ) Total sale-leaseback financing liability 5,000 Less current portion of sale-leaseback financing liability included in accounts payable and accrued expenses (287 ) Long-term portion of sale-leaseback financing liability included in other liabilities $ 4,713 As of June 30, 2016 and December 31, 2015, the net carrying value of the Denton facility assets that are included in property, plant, and equipment on our condensed consolidated balance sheets amounted to $12.9 million and $13.1 million, respectively. The useful life of the asset was modified to the remainder of the lease’s duration. The Company concluded there was a triggering event that required an impairment test to be performed to support the assets’ carrying value as a result of the carrying value of the long-lived assets being in excess of the gross proceeds received as a result of the sale-leaseback transaction. An undiscounted cash flow analysis was performed and the sum of the undiscounted cash flows exceeded the long-lived assets’ carrying value. As a result of this analysis, no impairment was recorded during the second quarter of 2016. Telford Facility On June 2, 2016, the Company entered into an agreement to sell its manufacturing facility in Telford, Pennsylvania for gross proceeds of $6.0 million, less costs associated with the transaction of $0.4 million, or net proceeds of $5.6 million. As a part of the transaction, the Company entered into a lease for the property from the purchaser for a period of 13 years. The Company recorded a deferred gain on the sale of this facility in the amount of $2.4 million recorded in the Condensed Consolidated Balance Sheets as an offset to property, plant, and equipment, which will be recognized over the 13-year lease term. As a result of this transaction, the Company initially recorded a capital lease obligation of $5.7 million for the facilities leased. The weighted-average effective interest rate of the capital lease was 3.43%. The future minimum payments for the capital lease as of June 30, 2016, are as follows (in thousands): Fiscal Years Payments Remainder of 2016 $ 241 2017 487 2018 497 2019 507 2020 517 2021 527 Thereafter 4,253 Total payments 7,029 Less amount representing interest (1,392 ) Present value of future minimum lease payments 5,637 Less current portion of capital lease obligation included in accounts payable and accrued expenses (293 ) Long-term portion of capital lease obligation included in other liabilities $ 5,344 Prior to the execution of this transaction, the Company did not have any assets held under capital leases.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies - Legal Matters	16. Commitments and Contingencies – Legal Matters Asbestos cases Our subsidiary, Met-Pro Technologies LLC (“Met-Pro”), beginning in 2002, began to be named in asbestos-related lawsuits filed against a large number of industrial companies including, in particular, those in the pump and fluid handling industries. In management’s opinion, the complaints typically have been vague, general and speculative, alleging that Met-Pro, along with the numerous other defendants, sold unidentified asbestos-containing products and engaged in other related actions which caused injuries (including death) and loss to the plaintiffs. Counsel has advised that more recent cases typically allege more serious claims of mesothelioma. The Company’s insurers have hired attorneys who, together with the Company, are vigorously defending these cases. Many cases have been dismissed after the plaintiff fails to produce evidence of exposure to Met-Pro’s products. In those cases where evidence has been produced, the Company’s experience has been that the exposure levels are low and the Company’s position has been that its products were not a cause of death, injury or loss. The Company has been dismissed from or settled a large number of these cases. Cumulative settlement payments from 2002 through June 30, 2016 for cases involving asbestos-related claims were $0.9 million, which, together with all legal fees other than corporate counsel expenses, have been paid by the Company’s insurers. The average cost per settled claim, excluding legal fees, was approximately $25,000. Based upon the most recent information available to the Company regarding such claims, there were a total of 217 cases pending against the Company as of June 30, 2016 (with Connecticut, New York, Pennsylvania and West Virginia having the largest number of cases), as compared with 221 cases that were pending as of December 31, 2015. During the six months ended June 30, 2016, 40 new cases were filed against the Company, and the Company was dismissed from 42 cases and settled two cases. Most of the pending cases have not advanced beyond the early stages of discovery, although a number of cases are on schedules leading to, or are scheduled for trial. The Company believes that its insurance coverage is adequate for the cases currently pending against the Company and for the foreseeable future, assuming a continuation of the current volume, nature of cases and settlement amounts. However, the Company has no control over the number and nature of cases that are filed against it, nor as to the financial health of its insurers or their position as to coverage. The Company also presently believes that none of the pending cases will have a material adverse impact upon the Company’s results of operations, liquidity or financial condition. Valero One of our subsidiaries, Fisher-Klosterman, Inc. (“FKI”), was a defendant in a products liability lawsuit filed in Harris County, Texas on August 23, 2010 by three Valero refining companies. The plaintiffs claimed that FKI (and its co-Defendants) used an allegedly defective refractory material included in cyclones it supplied to Valero that caused damages to refineries they own and operate. Plaintiffs claimed to have suffered property damages, including catalyst loss, regenerator repair costs, replacement part costs, damage to other property and business interruption loss. During the third quarter of 2014, the Company reached a settlement with the plaintiffs for $0.5 million and, accordingly, recorded a corresponding charge to operations. In addition, the Company reached an agreement with a supplier to recover $0.2 million related to this matter. The recovery was also recorded during the third quarter of 2014. The Company’s insurer, who had paid for the legal defense in this matter, initiated a new case in the Southern District of Ohio against the Company seeking, among other things, recoupment of past legal costs paid. The Company is vigorously disputing this claim, including the pursuit of counterclaims against the insurer, and obtained a preliminary ruling that its insurer was obligated to provide the Company a defense for the Valero litigation. PMFG shareholder lawsuits Since the public announcement of the proposed merger on May 4, 2015, CECO, Merger Sub I, Merger Sub II, PMFG and the members of the PMFG board of directors have been named as defendants in three lawsuits related to the acquisition, which were filed by alleged stockholders of PMFG on May 17, 2015, June 29, 2015 and July 17, 2015. The first filed lawsuit, which is a derivative action that also purports to assert class claims, was filed in the District Court of Dallas County, Texas (the “Texas Lawsuit”). The second and third filed lawsuits, which are class actions, were filed in the Court of Chancery of the State of Delaware and have now been consolidated into a single action (the “Delaware Lawsuit,” and collectively with the Texas Lawsuit, the “Lawsuits”). In the Lawsuits, the plaintiffs generally allege that the merger failed to properly value PMFG, that the individual defendants breached their fiduciary duties in approving the related merger agreement, and that those breaches were aided and abetted by CECO, Merger Sub I and Merger Sub II . In the Lawsuits, the plaintiffs allege, among other things, (a) that the PMFG board of directors board of directors In the Lawsuits, the plaintiffs sought, among other things, (a) to enjoin the defendants from completing the merger on the agreed-upon terms, (b) rescission, to the extent already implemented, of the merger agreement or any of the terms therein, and (c) costs and disbursements and attorneys’ and experts’ fees, as well as other equitable relief as the courts deem proper. Effective as of August 23, 2015, PMFG and the other defendants entered a memorandum of understanding with the plaintiffs in the Delaware Lawsuit regarding the settlement of the Delaware Lawsuit. In connection with this memorandum of understanding, PMFG agreed to make certain additional disclosures to PMFG’s stockholders in order to supplement those contained in the joint proxy statement/prospectus. After PMFG enters into a definitive agreement with the plaintiffs in the Delaware Lawsuit, the proposed settlement will be subject to notice to the class, Court approval, and, if the Court approves the settlement, the settlement, as outlined in the memorandum of understanding, will resolve all of the claims that were or could have been brought in the Delaware Lawsuit, including all claims relating to the decision to enter into the Mergers, entry of the Merger Agreement and any disclosure made in connection therewith including any such claims against CECO, Merger Sub I or Merger Sub II, but did not affect any stockholder’s rights to pursue appraisal rights. It is expected that the resolution of the Delaware Lawsuit will also resolve the Texas Lawsuit, which was stayed voluntarily by the plaintiff, but placed on Texas court’s two-week docket for a non-jury trial on August 15, 2016. On May 11, 2016, the Court entered an order preliminarily approving the proposed settlement and setting a hearing on July 13, 2016 during which it would consider whether to enter an order granting final approval of the proposed settlement, which hearing was subsequently rescheduled for September 14, 2016. Summary The Company is also a party to routine contract and employment-related litigation matters and routine audits of state and local tax returns arising in the ordinary course of its business. The final outcome and impact of open matters, and related claims and investigations that may be brought in the future, are subject to many variables, and cannot be predicted. In accordance with ASC 450, “Contingencies,” and related guidance, we record reserves for estimated losses relating to claims and lawsuits when available information indicates that a loss is probable and the amount of the loss, or range of loss, can be reasonably estimated. The Company expenses legal costs as they are incurred. We are not aware of pending claims or assessments, other than as described above, which may have a material adverse impact on our liquidity, financial position, results of operations, or cash flows.

The Company’s common stock trading price for the 15-trading day period was $9.6655. As a result, each of the remaining shares of PMFG common stock converted into the right to receive 0.6456 shares of Company common stock, or an approximate total of 7,602,166 shares of Company common stock in aggregate. In accordance with the proration and reallocation provisions of the merger agreement, because the $6.85 per share cash consideration was oversubscribed by PMFG shareholders prior to the election deadline, (a) each PMFG share for which a valid stock election was made or for which no valid cash or stock election was made was automatically cancelled and converted into the right to receive the stock consideration and (b) each PMFG shareholder of record that made a valid cash election by the deadline received (i) the cash consideration for approximately 58.05% of such holder’s PMFG shares for which a valid cash election was made and (ii) the stock consideration for approximately 41.95% of such holder’s PMFG shares for which a valid cash election was made. The value of stock recorded for purchase accounting was $72.1 million, which equates to approximately $9.49 per share. PMFG is a global provider of engineered equipment for the abatement of air pollution, the separation and filtration of contaminants from gases and liquids, and industrial noise control equipment, which complements our Energy Segment businesses. The following table summarizes the approximate fair values of the assets acquired and liabilities assumed at the date of closing. (Table only in thousands) Current assets (including cash of $27,100) $ 92,690 Property and equipment 29,982 Other assets 953 Assets held for sale (a) 950 Deferred income tax asset — Goodwill 56,020 Intangible – finite life 29,940 Intangible – indefinite life 10,280 Total assets acquired 220,815 Current liabilities assumed (73,328 ) Deferred income tax liability (800 ) Long term liabilities assumed (3,961 ) Noncontrolling interest (6,000 ) Net assets acquired $ 136,726 (a) The assets held for sale consist primarily of real property, and are valued at the estimated proceeds less cost to sell. The Company has not recorded a gain or loss on the classification of the subject assets to held for sale. The Company expects to complete the sale of the subject assets within the next twelve months. For the three months ended June 30, 2016, PMFG accounted for $25.0 million of revenue and $1.7 million of pre-tax income included in the Company’s results. For the six months ended June 30, 2016, PMFG accounted for $49.9 million of revenue and $4.9 million of pre-tax income included in the Company’s results. The approximate fair values of the assets acquired and liabilities assumed, and the related tax balances, are based on preliminary estimates and assumptions. These preliminary estimates and assumptions could change significantly during the purchase price measurement period as we finalize the valuations of the assets acquired and liabilities assumed, and the related tax balances. Such changes could result in material variances between the Company’s future financial results and the amounts presented in the unaudited pro forma information, including variances in the estimated purchase price, fair values recorded and expenses associated with these items. The following unaudited pro forma information represents the Company’s results of operations as if the PMFG acquisition had occurred as of January 1, 2014: Three Months Ended June 30, Six Months Ended June 30, (Table only in thousands, except per share data) 2015 2015 Net sales $ 124,659 $ 240,410 Net loss (5,434 ) (8,195 ) Earnings per share: Basic $ (0.16 ) $ (0.24 ) Diluted $ (0.16 ) $ (0.24 ) The pro forma results have been prepared for informational purposes only and include adjustments to amortize acquired intangible assets with finite life, reflect foregone interest income on cash paid for the acquisitions, reflect additional interest expense on debt used to fund the acquisitions, and to record the income tax consequences of the pro forma adjustments. Included in the pro forma results are acquisition related expenses of $1.0 million and $1.3 million for the three-month and six-month periods ended June 30, 2015, respectively. Shares used to calculate the basic and diluted earnings per share were adjusted to reflect the additional shares of common stock issued to fund a portion of the acquisition price. These pro forma results do not purport to be indicative of the results of operations that would have occurred had the purchases been made as of the beginning of the periods presented or of the results of operations that may occur in the future. Acquisition and integration expenses on the Condensed Consolidated Statements of Income are related to acquisition activities, which include retention, legal, accounting, banking, and other expenses.

Segment Reporting [Abstract]
Business Segment Information	18. Business Segment Information The Company’s operations are organized and reviewed by management along its product lines and presented in three reportable segments. Environmental Segment Our Environmental segment, formerly known as the Air Pollution Control segment, provides the design and manufacture of product recovery and air pollution control technologies that enable our customers to meet compliance targets for toxic emissions, fumes, volatile organic compounds, process and industrial odors. These products and solutions include chemical and biological scrubbers, fabric filters and cartridge collectors, thermal and catalytic oxidation systems, cyclones, separators, gas absorbers and industrial ventilation systems. This segment also provides component parts for industrial air systems and provides cost effective alternatives to traditional duct components, as well as custom metal engineered fabrication services. These products and services are applicable to a wide variety of industries. During 2015, the Company concluded that changing the name of this segment was appropriate to more accurately describe the long-term goals of the Company in conjunction with the products and services offered within the segment . Energy Segment Our Energy segment provides customized solutions for the power and petrochemical industry. This includes gas turbine exhaust systems, dampers and diverters, gas and liquid separation and filtration equipment, selective catalytic reduction (“SCR”) and selective non-catalytic reduction (“SNCR”) systems, acoustical components and silencers, secondary separators (nuclear plant reactor vessels) and expansion joints, the design and manufacture of technologies for flue gas and diverter dampers, non-metallic expansion joints, natural gas turbine exhaust systems, and silencer and precipitator applications, primarily for coal-fired and natural gas power plants, refining, oil production and petrochemical processing, as well as a variety of other industries. Fluid Handling and Filtration Segment Our Fluid Handling and Filtration (“FHF”) segment provides the design and manufacture of high quality pump, filtration and fume exhaust solutions. This includes centrifugal pumps for corrosive, abrasive and high temperature liquids, filter products for air and liquid filtration, precious metal recovery systems, carbonate precipitators, and technologically advanced air movement and exhaust systems. These products are applicable to a wide variety of industries, particularly the aquarium/aquaculture, plating and metal finishing, food and beverage, chemical/petrochemical, wastewater treatment, desalination and pharmaceutical markets. The accounting policies of the reporting segments are the same as those described in the summary of significant accounting policies in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015 filed with the SEC. Interest income and expense are not included in the measure of segment profit reviewed by management. Income taxes are also not included in the measure of segment operating profit reviewed by management. The operating results of the segments are reviewed through to the “Income from operations” line on the Condensed Consolidated Statements of Income.

New Financial Accounting Pron25

New Financial Accounting Pronouncements (Policies)	6 Months Ended
	Jun. 30, 2016
Accounting Changes And Error Corrections [Abstract]
New Financial Accounting Pronouncements Adopted	In May 2016, the Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) These pronouncements have the same effective date as the new revenue standard, which is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. The Company is currently evaluating the impact of the adoption of these standards on the Company’s consolidated financial statements and has not yet determined the method of adoption. In March 2016, the FASB issued ASU 2016-09, “Compensation—Stock Compensation: Improvements to Employee Share-Based Payment Accounting .” In March 2016, the FASB issued ASU 2016-05, “Derivatives and Hedging: Effect of Derivative Contract Novations on Existing Hedge Accounting Relationships.” ASU 2016-09 is effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. The Company is currently evaluating the potential impact of the adoption of this standard on the Company’s consolidated financial statements In February 2016, the FASB issued ASU 2016-02, “Leases.” ASU 2016-02 establishes a right-of-use (“ROU”) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. The Company is currently evaluating the potential impact of the adoption of ASU 2016-02 on the Company’s consolidated financial statements . In July 2015, the FASB issued ASU 2015-11, “Simplifying the Measurement of Inventory.” ASU 2015-11 requires inventory within the scope of the ASU (e.g., first-in, first-out (“FIFO”) or average cost) to be measured using the lower of cost and net realizable value. Inventory excluded from the scope of the ASU (i.e., last-in, first-out (“LIFO”) or the retail inventory method) will continue to be measured at the lower of cost or market. The ASU also amends some of the other guidance in Topic 330, “Inventory,” to more clearly articulate the requirements for the measurement and disclosure of inventory. However, those amendments are not intended to result in any changes to current practice. ASU 2015-11 is effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. The adoption of this standard is not expected to have a significant impact on the Company’s consolidated financial statements . In May 2014, the FASB issued ASU 2014-09, “Revenue From Contracts With Customers.” ASU 2014-09 supersedes nearly all existing revenue recognition principles under GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration an entity expects to be entitled to for those goods or services using a defined five step process. More judgment and estimates may be required to achieve this principle than under existing GAAP. ASU 2014-09 is effective for annual periods beginning after December 15, 2017, including interim periods therein, using either of the following transition methods: (i) a full retrospective approach reflecting the application of the standard in each prior reporting period with the option to elect certain practical expedients or (ii) a retrospective approach with the cumulative effect upon initial adoption recognized at the date of adoption, which includes additional footnote disclosures. The Company is currently evaluating the impact of the adoption of ASU 2014-09 on the Company’s consolidated financial statements and has not yet determined the method of adoption . The Company’s current revenue recognition policies are generally consistent with the new revenue recognition standards set forth in ASU 2014-09. Potential adjustments to input measures are not expected to be pervasive to the majority of the Company’s contracts. While no significant impact is expected upon adoption of the new guidance, the Company will not be able to make that determination until the time of adoption based upon outstanding contracts at that time.
