BASIS OF PRESENTATION AND ACCOUNTING POLICIES [Abstract]
BASIS OF PRESENTATION AND ACCOUNTING POLICIES	1. BASIS OF PRESENTATION AND ACCOUNTING POLICIES The condensed consolidated balance sheets, statements of operations, comprehensive income and cash flows for the periods presented herein have been prepared by the Company and are unaudited. In the opinion of management, all adjustments (consisting solely of normal recurring adjustments) necessary to present fairly the consolidated financial position, results of operations and cash flows for all periods presented have been made. The results for the three and nine months ended September 30, 2018 are not necessarily indicative of the results to be expected for the full year. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and footnotes thereto included in the Bel Fuse Annual Report on Form 10-K for the year ended December 31, 2017. Certain information and footnote disclosures required under accounting principles generally accepted in the United States of America ("U.S. GAAP") have been condensed or omitted from the following condensed consolidated financial statements pursuant to the rules and regulations, including the interim reporting requirements, of the SEC. The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts and the disclosure of contingent amounts in our condensed consolidated financial statements and accompanying notes. Actual results could differ from these estimates. The Company's significant accounting policies are summarized in Note 1 of the Company's Annual Report on Form 10-K for the year ended December 31, 2017. There were no significant changes to these accounting policies during the nine months ended September 30, 2018, except as discussed in Note 2, Revenue, related to the adoption of the new revenue standards. All amounts included in the tables to these notes to condensed consolidated financial statements, except per share amounts, are in thousands. Recently Adopted Accounting Standards In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) Upon adoption, the new revenue standards replaced most existing revenue recognition guidance in U.S. GAAP. Based on our review of representative samples of contracts and other forms of agreements with customers globally and our evaluation of the provisions under the five-step model specified by the new revenue standards, the Company has implemented changes with respect to timing of revenue recognition primarily related to arrangements for which the customer takes the Company's products from a facility holding consignment inventory. In connection with the modified retrospective application of the new revenue standards, we recorded an adjustment to increase retained earnings of $3.4 million upon the January 1, 2018 adoption date. Apart from this adjustment and the inclusion of additional required disclosures in Note 2, the adoption of the new revenue standards did not have a material impact on the Company's condensed consolidated financial statements. In January 2016, the FASB issued ASU 2016-01, Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments guidance was adopted by the Company effective January 1, 2018 and it did not have any impact on the Company's condensed consolidated statement of cash flows in the periods presented. In October 2016, the FASB issued ASU 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory . Current U.S. GAAP prohibits the recognition of current and deferred income taxes for intra-entity asset transfer until the asset has been sold to an was effective for annual reporting periods beginning after December 15, 2017, including interim reporting periods within those annual reporting periods, and should be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. This guidance was adopted by the Company effective January 1, 2018 and it did not have a material impact on the Company's condensed consolidated financial position or results of operations. In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business In March 2017, the FASB issued ASU 2017-07, Compensation – Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost In May 2017, the FASB issued ASU 2017-09, Compensation – Stock Compensation (Topic 718): Scope of Modification Accounting ("ASU 2017-09") Accounting Standards Issued But Not Yet Adopted In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) , to provide a new comprehensive model for lease accounting. Under In January 2017, the FASB issued Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment In February 2018, the FASB issued ASU 2018-02, Income Statement – Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income We are currently in the process of evaluating this new standard update.

REVENUE

REVENUE	9 Months Ended

REVENUE [Abstract]
REVENUE	2. REVENUE Significant Accounting Policy On January 1, 2018, the Company adopted ASC 606 using the modified retrospective method applied to those contracts which were not completed as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under ASC 606, while prior period amounts are not adjusted and continue to be reported in accordance with our historical accounting under ASC 605. The adoption of ASC 606 represents a change in accounting principle that will more closely align revenue recognition with the transfer of control of the Company's goods and services and provides financial statement readers with enhanced disclosures related to the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. In accordance with ASC 606, revenue is recognized when a customer obtains control of promised goods or services. The amount of revenue recognized reflects the consideration to which the Company expects to be entitled to receive in exchange for these goods and services. Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction, that are collected by the Company from a customer, are excluded from revenue. Shipping and handling costs associated with outbound freight after control over a product has transferred to a customer are accounted for as a fulfillment cost and are included in cost of sales. Nature of Goods and Services Our revenues are substantially derived from sales of our products. In our connectivity solutions product group, we provide connectors and cable assemblies to the aerospace, military/defense, commercial, rugged harsh environment and communication markets. This group also includes passive jacks, plugs and cable assemblies that provide connectivity in networking equipment, as well as modular plugs and cable assemblies used within the structured cabling system, known as premise wiring. In our power solutions and protection group, we provide AC-DC and DC-DC power conversion devices and circuit protection products. Applications range from board-mount power to system-level architectures for servers, storage, networking, industrial and transportation. In our magnetic solutions group, we provide an extensive line of integrated connector modules (ICM), where an Ethernet magnetic solution is integrated into a connector package. Products within the Company's magnetic solutions group are primarily used in networking and industrial applications. The Company also provides incremental services to our customers in the form of training, technical support, special tooling, and other support as deemed necessary from time to time. For purposes of ASC 606, all such incremental services were concluded to be immaterial in the context of the contracts. Types of Contracts Substantially all of the Company's revenue is derived from contracts with its customers under one of the following types of contracts: · Direct with customer: · Distributor: · Consignment: · Licensing Agreements: Warranties Warranties vary by product line and are competitive for the markets in which the Company operates. Warranties generally extend for one to three years from the date of sale, providing customers with assurance that the related product will function as intended. The Company reviews its warranty liability quarterly based on an analysis of actual expenses and failure rates accompanied with estimated future costs and projected failure rate trends. Factors taken into consideration when evaluating our warranty reserve are (i) historical claims for each product, (ii) volume increases, (iii) life of warranty, (iv) historical warranty repair costs and (v) other factors. To the extent that actual experience differs from our estimate, the provision for product warranties will be adjusted in future periods. Actual warranty repair costs are charged against the reserve balance as incurred. See Note 7, "Accrued Expenses." Product Returns We estimate product returns, including product exchanges under warranty, based on historical experience. In general, the Company is not contractually obligated to accept returns except for defective product or in instances where the product does not meet the Company's product specifications. However, the Company may permit its customers to return product for other reasons. In certain instances, the Company would generally require a significant cancellation penalty payment by the customer. The Company estimates such returns, where applicable, based upon management's evaluation of historical experience, market acceptance of products produced and known negotiations with customers. Such estimates are deducted from sales and provided for at the time revenue is recognized. Distribution customers often receive what is referred to as "ship and debit" arrangements, whereby Bel will invoice them at an agreed upon unit price upon shipment of product and a price reduction may be granted if the market price of the product declines after shipment. Distributors may also be entitled to special pricing discount credits, and certain customers are entitled to return allowances based on previous sales volumes. Bel deducts estimates for anticipated credits, refunds and returns from sales each quarter based on historical experience. Significant Payment Terms Contracts with customers indicate the general terms and conditions in which business will be conducted for a set period of time. Individual purchase orders state the description, quantity and price of each product purchased. Payment for products sold under direct contracts with customers or contracts with distributors is typically due in full within 30-90 days from the transfer of title to customer. Payment for products sold under consignment contracts is typically due within 60 days of the customer pulling the product from the hub. Payment due related to our licensing agreements is generally within 30 days of receiving the licensee sales data, which is either on a quarterly or annual basis. Since the customer agrees to a stated price for each product on each purchase order, the majority of contracts are not subject to variable consideration. However, the "ship and debit" arrangements with distributors, royalty income associated with our licensing agreements, and the product returns described above are each deemed to be variable consideration which requires the Company to make constrained estimates based on historical data.

In the case of our consignment arrangements, we are unable to invoice the customer until product is pulled from the hub by the customer, which generates an unbilled receivable (a contract asset) when revenue is initially recognized. A contract liability results when cash payments are received or due in advance of our performance obligation being met. We have certain customers who provide payment in advance of product being shipped, which results in deferred revenue (a contract liability). The balances of the Company's contract assets and contract liabilities at September 30, 2018 are as follows: September 30, January 1, 2018 2018 Contract assets - current (unbilled receivable) $ 16,553 $ 14,536 Contract liabilities - current (deferred revenue) $ 776 $ 855 The change in balance of our unbilled receivables from January 1, 2018 to September 30, 2018 primarily relates to a timing difference between the Company's performance (i.e. when our product is shipped to a customer-controlled hub) and the point at which the Company can invoice the customer per the terms of the customer contract (i.e. when the customer pulls our product from the customer-controlled hub). A tabular presentation of the activity within the deferred revenue account for the nine months ended September 30, 2018 is presented below: Nine Months Ended September 30, 2018 Balance, January 1 $ 855 New advance payments received 6,180 Recognized as revenue during period (6,251 ) Currency translation (8 ) Balance, September 30 $ 776 Transaction Price Allocated to Future Obligations The aggregate amount of transaction price allocated to remaining performance obligations that have not been satisfied as of September 30, 2018 related to contracts that exceed one year in duration amounted to $17.6 million, with expected contract expiration dates that range from 2019 - 2024. It is expected that 14% of this aggregate amount will be recognized in the fourth quarter of 2019, 52% will be recognized in 2020 and the remainder will be recognized in years beyond 2020. The majority of the Company's total backlog of orders at September 30, 2018 is related to contracts that have an original expected duration of one year or less, for which the Company is electing to utilize the practical expedient available within the guidance, and are excluded from the transaction price related to these future obligations. The Company will generally satisfy the remaining performance obligations as we transfer control of the products ordered to our customers. The transaction price related to these future obligations also excludes variable consideration consisting of sales or usage-based royalties earned on licensing agreements. The variability related to these sales or usage-based royalties will be resolved in the periods when the licensee generates sales related to the licensed intellectual property. Other Practical Expedients: In the application of the recognition and measurement principles of ASC 606, the Company elected to utilize the following additional practical expedients which are provided for within the guidance: · Financing Components · Costs to Obtain a Contract

FAIR VALUE MEASUREMENTS [Abstract]
FAIR VALUE MEASUREMENTS	4. FAIR VALUE MEASUREMENTS F Level 1 Observable inputs such as quoted market prices in active markets; Level 2 Inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3 Unobservable inputs about which little or no market data exists, therefore requiring an entity to develop its own assumptions. As of December 31, 2017, the Company held certain financial assets that are measured at fair value on a recurring basis. These consisted of securities that are among the Company's investments in a rabbi trust which are intended to fund the Company's Supplemental Executive Retirement Plan ("SERP") obligations. The gross unrealized gains associated with the investment securities held in the rabbi trust were $0.2 million at December 31, 2017. Such unrealized gains are included, net of tax, in accumulated other comprehensive loss. During the nine months ended September 30, 2018, the Company sold its securities and realized a gain on sale of $0.2 million. The proceeds of $1.3 million were reinvested in other securities within the rabbi trust. As of September 30, 2018 and December 31, 2017, our securities primarily consisted of investments held in a rabbi trust of $1.3 million and $1.5 million, respectively, which were measured at fair value using quoted prices in active markets for identical assets (Level 1) inputs. The Company does not have any financial assets measured at fair value on a recurring basis categorized as Level 3, and there were no transfers in or out of Level 1, Level 2 or Level 3 during the nine months ended September 30, 2018 or September 30, 2017. Excluding the changes made in accordance with the Company’s adoption of ASU 2016-01, there were no changes to the Company's valuation techniques used to measure asset fair values on a recurring or nonrecurring basis during the nine months ended September 30, 2018. There were no financial assets accounted for at fair value on a nonrecurring basis as of September 30, 2018 or December 31, 2017. The Company has other financial instruments, such as cash and cash equivalents, accounts receivable, restricted cash, accounts payable, accrued expenses and notes payable, which are not measured at fair value on a recurring basis but are recorded at amounts that approximate fair value due to their liquid or short-term nature. The fair value of the Company's long-term debt is estimated using a discounted cash flow method based on interest rates that are currently available for debt issuances with similar terms and maturities. At September 30, 2018 and December 31, 2017, the estimated fair value of total debt was $116.9 million and $124.8 million, respectively, compared to a carrying amount of $114.8 million and $122.7 million, respectively. The Company did not have any other financial liabilities within the scope of the fair value disclosure requirements as of September 30, 2018. Nonfinancial assets and liabilities, such as goodwill, indefinite-lived intangible assets and long-lived assets, are accounted for at fair value on a nonrecurring basis. These items are tested for impairment upon the occurrence of a triggering event or in the case of goodwill, on at least an annual basis. There were no triggering events that occurred during the nine months ended September 30, 2018 that would warrant interim impairment testing.

DEBT [Abstract]
DEBT	8. DEBT The Company has a Credit and Security Agreement with KeyBank National Association (as amended, the "CSA"). The CSA consists of (i) a term loan, with outstanding borrowings of $116.7 million and $125.0 million at September 30, 2018 and December 31, 2017, respectively and (ii) a $75 million revolving credit facility ("Revolver"), with no outstanding borrowings at September 30, 2018 or December 31, 2017. The CSA has a maturity date of December 11, 2022. At September 30, 2018 and December 31, 2017, the carrying value of the debt on the condensed consolidated balance sheet is reflected net of $1.9 million and $2.3 million, respectively, of deferred financing costs. During the nine months ended September 30, 2018, the Company made voluntary prepayments of $6.0 million. Per the terms of the CSA, such voluntary prepayments reduce the amount of future scheduled payments on a pro rata basis. The weighted-average interest rate in effect was 4.25% at September 30, 2018 and 3.38% at December 31, 2017 and consisted of LIBOR plus the Company's credit spread, as determined per the terms of the CSA. The Company incurred $1.4 million and $1.5 million of interest expense during the three months ended September 30, 2018 and September 30, 2017, respectively, and $3.9 million and $4.5 million of interest expense during the nine months ended September 30, 2018 and September 30, 2017, respectively. The CSA contains customary representations and warranties, covenants and events of default and financial covenants that measure (i) the ratio of the Company's total funded indebtedness, on a consolidated basis, to the amount of the Company's consolidated EBITDA, as defined, ("Leverage Ratio") and (ii) the ratio of the amount of the Company's consolidated EBITDA to the Company's consolidated fixed charges. If an event of default occurs, the lenders under the CSA would be entitled to take various actions, including the acceleration of amounts due thereunder and all actions permitted to be taken by a secured creditor. At September 30, 2018, the Company was in compliance with its debt covenants, including its most restrictive covenant, the Fixed Charge Coverage Ratio.

INCOME TAXES

INCOME TAXES [Abstract]
INCOME TAXES	9. INCOME TAXES The Company and its subsidiaries file income tax returns in the U.S. federal jurisdiction and various states and foreign jurisdictions. The Company is no longer subject to U.S. federal examinations by tax authorities for years before 2015 and for state examinations before 2012. Regarding foreign subsidiaries, the Company is no longer subject to examination by tax authorities for years before 2008 in Asia and generally 2010 in Europe. As a result of the expiration of the statutes of limitations for specific jurisdictions, it is reasonably possible that the related unrecognized benefits for tax positions taken regarding previously filed tax returns may change materially from those recorded as liabilities for uncertain tax positions in the Company's consolidated financial statements at September 30, 2018. The Company's liabilities for uncertain tax positions totaled $28.2 million and $30.4 million at September 30, 2018 and December 31, 2017, respectively, of which $1.1 million and $2.5 million is included in other current liabilities at September 30, 2018 and December 31, 2017, respectively. These amounts, if recognized, would reduce the Company's effective tax rate. As of September 30, 2018, approximately $2.5 million of the Company's liabilities for uncertain tax positions were resolved during 2018 by way of expiration of the related statute of limitations. The Company's policy is to recognize interest and penalties related to uncertain tax positions as a component of the current provision for income taxes. During the nine months ended September 30, 2018 and 2017, the Company recognized $0.7 million and $0.6 million, respectively, in interest and penalties in the consolidated statements of operations. During the three and nine months ended September 30, 2018, the Company recognized for the reversal of such interest and penalties, relating to the expiration of statutes of limitations and settlement of the acquired liability for uncertain tax positions. The Company has approximately $3.1 million and $3.2 million accrued for the payment of interest and penalties at September 30, 2018 and December 31, 2017, respectively, which is included in both income taxes payable and liability for uncertain tax positions in the consolidated balance sheets. Tax Reform The Tax Cuts and Jobs Act (the "Act") was enacted on December 22, 2017. The Act reduces the U.S. federal corporate tax rate from 35% to 21%, requires companies to pay a one-time transition tax on earnings of certain foreign subsidiaries that were previously tax deferred and creates new taxes on certain foreign sourced earnings. At December 31, 2017, we had not completed our accounting for the tax effects of enactment of the Act; however, we had made a reasonable estimate of the effects on our existing deferred tax balances and the one-time transition tax in which we recognized a provisional amount of $18.1 million, which was included as a component of income tax expense from continuing operations. During the nine months ended September 30, 2018, the Company has made measurement-period adjustments related to foreign earnings and profits computations and foreign income tax calculations for the Company's non-U.S. subsidiaries. The Company's measurement-period adjustment reduced its estimate of the deemed repatriation tax by $2.6 million, resulting in the reduction of the Company's provisional estimate from $18.1 million to $15.5 million. The Company plans to pay the tax in installments in accordance with the Act. Effective January 1, 2018, the Act subjects a U.S. shareholder to current tax on global intangible low-taxed income (GILTI) earned by certain foreign subsidiaries. The Company has elected an accounting policy to provide for the tax expense related to the GILTI in the period the tax is incurred.

COMMITMENTS AND CONTINGENCIES [Abstract]
COMMITMENTS AND CONTINGENCIES	12. COMMITMENTS AND CONTINGENCIES Legal Proceedings The Company is party to a number of legal actions and claims, none of which individually or in the aggregate, in the opinion of management, are expected to have a material adverse effect on the Company's consolidated results of operations or financial position. In connection with the acquisition of Power Solutions, there is an ongoing claim by the Arezzo Revenue Agency in Italy concerning certain tax matters related to what was then Power-One Asia Pacific Electronics Shenzhen Co. Ltd. (now Bel Power Solutions Asia Pacific Electronics Shenzhen Co. Ltd, or "BPS China") for the years 2004 to 2006. In September 2012, the Tax Court of Arezzo ruled in favor of BPS China and cancelled the claim. In February 2013, the Arezzo Revenue Agency filed an appeal of the Tax Court's ruling. The hearing of the appeal was held on October 2, 2014. On October 13, 2014, BPS China was informed of the Regional Tax Commission of Florence ruling which was in favor of the Arezzo Revenue Agency and against BPS China. An appeal was filed on July 18, 2015 before the Regional Tax Commission of Florence and rejected. On December 5, 2016, the Arezzo Revenue Agency filed an appeal with the Supreme Court and BPS China filed a counter-appeal on January 4, 2017. The Supreme Court has yet to render its judgment. The estimated liability related to this matter is approximately $12.0 million and has been included as a liability for uncertain tax positions on the accompanying condensed consolidated balance sheets. As Bel is fully indemnified in this matter per the terms of the stock purchase agreement with ABB, a corresponding other asset for indemnification is also included in other assets on the accompanying consolidated balance sheets at September 30, 2018 and December 31, 2017. In 2015, the Company was provided notice of a potential patent infringement claim by Setec Netzwerke AG ("Setec"), a German company for the alleged infringement of their patent EP 306 934 B1. Setec subsequently filed a lawsuit against the Company and three of its subsidiaries in the Regional Court of Dusseldorf, Germany on January 29, 2016 for patent infringement. The Company filed its defense to Setec's Complaint and a nullity lawsuit against Setec's patent on August 31 2016. The Court hearing on infringement took place on March 23, 2017. Upon hearing argument from both parties, the Court issued a decision on April 6, 2017 staying final judgment in the infringement case pending resolution of the nullity lawsuit in the Federal Patents Courts in Munich, Germany. The Federal Patents Courts issued its preliminary opinion regarding the patent-in-suit on March 29, 2018, stating that it considers the patent-in-suit to not be novel over the prior art documents presented in the case. The parties agreed to withdraw from the pending infringement and nullity proceedings and entered into a settlement agreement on June 29, 2018. The Company paid Setec 75,000 Euro in exchange for a perpetual, worldwide royalty-free license to the patent-in-suit and all its counterparts. In 2015, one of the Company's subsidiaries in the PRC, Dongguan Transpower Electric Products Co., Ltd. ("Dongguan Transpower"), was provided notice of a claim by DG Yu Shing Industrial Development Company Limited against Dongguan Transpower and three other defendants for past due construction costs of approximately $3.2 million. In April 2018, the 3 rd People Court of Dongguan ruled and provided an unfavorable judgment against Dongguan Transpower and two of the other defendants requiring payment of the aforementioned amount. The defendants were held to be jointly and severally liable for approximately $3.2 million in costs. Due to the fact that none of the other defendants had sufficient funds to pay the damages amount, the Court ordered the entire amount (CNY 20,133,174.10) to be paid by Dongguan Transpower. On May 25, 2018, the Court enforced its order and withdrew the damages amount from Dongguan Transpower's bank accounts. On May 31, 2018, Dongguan Transpower filed an action against the other defendants in CP Court to recoup the damages amount paid pursuant to an indemnification letter dated October 16, 2015. The Court heard arguments on July 2, 2018 and rendered a verdict on July 9, 2018 ordering the Jinmei entities (defendants) to pay CNY 20,133,174 back to Dongguan Transpower together with the incurred interest. On August 27, 2018, Dongguan Transpower received payment of CNY 20,430,203 (approximately $3.2 million) from the defendants and this case was closed. On June 1, 2018, the Company filed an action against Unipower, LLC in the United States District Court for the Southern District of New York for breach of contract. Specifically, the Company alleges in its Complaint that Unipower has willfully violated the Master Services Agreement ("MSA") entered into by the parties on January 23, 2015 by failing to make payment for the products it contracted for under the MSA. The Company is claiming irreparable harm and substantial damages in excess of $1.0 million. The case is currently in the discovery phase of the litigation. The Company is not a party to any other legal proceeding, the adverse outcome of which is likely to have a material adverse effect on the Company's consolidated financial condition or results of operations.

Recently Adopted Accounting Standards	Recently Adopted Accounting Standards In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) Upon adoption, the new revenue standards replaced most existing revenue recognition guidance in U.S. GAAP. Based on our review of representative samples of contracts and other forms of agreements with customers globally and our evaluation of the provisions under the five-step model specified by the new revenue standards, the Company has implemented changes with respect to timing of revenue recognition primarily related to arrangements for which the customer takes the Company's products from a facility holding consignment inventory. In connection with the modified retrospective application of the new revenue standards, we recorded an adjustment to increase retained earnings of $3.4 million upon the January 1, 2018 adoption date. Apart from this adjustment and the inclusion of additional required disclosures in Note 2, the adoption of the new revenue standards did not have a material impact on the Company's condensed consolidated financial statements. In January 2016, the FASB issued ASU 2016-01, Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments guidance was adopted by the Company effective January 1, 2018 and it did not have any impact on the Company's condensed consolidated statement of cash flows in the periods presented. In October 2016, the FASB issued ASU 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory . Current U.S. GAAP prohibits the recognition of current and deferred income taxes for intra-entity asset transfer until the asset has been sold to an was effective for annual reporting periods beginning after December 15, 2017, including interim reporting periods within those annual reporting periods, and should be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. This guidance was adopted by the Company effective January 1, 2018 and it did not have a material impact on the Company's condensed consolidated financial position or results of operations. In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business In March 2017, the FASB issued ASU 2017-07, Compensation – Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost In May 2017, the FASB issued ASU 2017-09, Compensation – Stock Compensation (Topic 718): Scope of Modification Accounting ("ASU 2017-09")
