DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES [Abstract]
DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	1. DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Bel Fuse Inc. and subsidiaries ("Bel," the "Company," ) design, manufacture and sell a broad array of products that power, protect and connect electronic circuits. These products are used in the networking, telecommunication, high-speed data transmission, commercial aerospace, military, broadcasting, transportation and consumer electronic industries around the world. We manage our operations geographically through our three reportable operating segments: North America, Asia and Europe. On June 19, 2014, we completed the acquisition of 100% of the issued and outstanding capital stock of the Power-One Power Solutions business ("Power Solutions") of ABB Ltd. On July 25, 2014, we completed the acquisition of 100% of the issued and outstanding capital stock of the U.S. and U.K. Connectivity Solutions businesses from Emerson Electric Co. ("Emerson"). On August 29, 2014, we completed the acquisition of the Connectivity Solutions business in China from Emerson (collectively with the U.S. and U.K. portion of the transaction, "Connectivity Solutions"). The acquisitions of Power Solutions and Connectivity Solutions may hereafter be referred to collectively as either the "2014 Acquisitions" or the "2014 Acquired Companies". Accordingly, as of the respective acquisition dates, all of the assets acquired and liabilities assumed were recorded at their preliminary fair values and the Company's consolidated results of operations for the years ended December 31, 2016, 2015 and 2014 include the operating results of the acquired companies from their respective acquisition dates through the respective period end dates. The consolidated financial statements for the year ended December 31, 2014 reflect measurement period adjustments related to the 2014 Acquisitions. The measurement period adjustments were finalized within the respective measurement periods, and, in the aggregate, were not considered material to the consolidated financial statements. See Note 2, "Acquisitions and Disposition," for further details. All amounts included in the tables to these notes to consolidated financial statements, except per share amounts, are in thousands. Principles of Consolidation - Use of Estimates - to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an on-going basis, we evaluate our estimates, including but not limited to those related to product returns, provisions for bad debt, inventories, goodwill, intangible assets, investments, Supplemental Executive Retirement Plan ("SERP") expense, income taxes, contingencies and litigation. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. Cash Equivalents Allowance for Doubtful Accounts Effects of Foreign Currency – In non-U.S. locations that are not considered highly inflationary, we translate the balance sheets at the end of period exchange rates with translation adjustments accumulated within stockholders' equity on our consolidated balance sheets. We translate the statements of operations at the average exchange rates during the applicable period. In connection with foreign currency denominated transactions, including multi-currency intercompany payable and receivable transactions and loans, the Company incurred net realized and unrealized currency exchange gains of $3.1 million, $5.1 million and $4.3 million for the years ended December 31, 2016, 2015 and 2014, respectively, were included in SG&A expenses on the consolidated statements of operations. Concentration of Credit Risk - We place temporary cash investments with quality financial institutions and commercial issuers of short-term paper and, by policy, limit the amount of credit exposure in any one financial Inventories Revenue Recognition For certain customers, we provide consigned inventory, either at the customer's facility or at a third-party warehouse. Sales of consigned inventory are recorded when the customer withdraws inventory from consignment . 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 these 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. Product Warranties Goodwill and Identifiable Intangible Assets Identifiable intangible assets consist primarily of patents, licenses, trademarks, trade names, customer lists and relationships, non-compete agreements and technology based intangibles and other contractual agreements. We amortize finite lived identifiable intangible assets over the shorter of their stated or statutory duration or their estimated useful lives, ranging from 1 to 29 years, on a straight-line basis to their estimated residual values and periodically review them for impairment. Total identifiable intangible assets comprise 17.5% and 15.2% in 2016 and 2015, respectively, of our consolidated total assets. We use the acquisition method of accounting for all business combinations and do not amortize goodwill or intangible assets with indefinite useful lives. Goodwill and intangible assets with indefinite useful lives are tested for possible impairment annually during the fourth quarter of each fiscal year or more frequently if events or changes in circumstances indicate that the asset might be impaired. Impairment and Disposal of Long-Lived Assets For indefinite-lived intangible assets, such as trademarks and trade names, each year and whenever impairment indicators are present, we determine the fair value of the asset and record an impairment loss for the excess of book value over the fair value, if any. In addition, in all cases of an impairment review we re-evaluate whether continuing to characterize the asset as indefinite-lived is appropriate. See Note 4, "Goodwill and Other Intangible Assets," for additional details. Depreciation - Income Taxes - We record net deferred tax assets to the extent we believe these assets will more-likely-than-not be realized. In making such determination, we consider all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax planning strategies and recent financial operations. We have established valuation allowances for deferred tax assets that are not likely to be realized. In the event we were to determine that we would be able to realize our deferred income tax assets in the future in excess of our net recorded amount, we would adjust the valuation allowance, which would reduce the provision for income taxes. We establish reserves for tax contingencies when, despite the belief that our tax return positions are fully supported, it is probable that certain positions may be challenged and may not be fully sustained. The tax contingency reserves are analyzed on a quarterly basis and adjusted based upon changes in facts and circumstances, such as the conclusion of federal and state audits, expiration of the statute of limitations for the assessment of tax, case law and emerging legislation. Our effective tax rate includes the effect of tax contingency reserves and changes to the reserves as considered appropriate by management. Earnings per Share The earnings and weighted average shares outstanding used in the computation of basic and diluted earnings per share are as follows: 2016 2015 2014 Numerator: Net (loss) earnings $ (64,834 ) $ 19,197 $ 8,603 Less dividends declared: Class A 522 522 522 Class B 2,728 2,713 2,665 Undistributed (loss) earnings $ (68,084 ) $ 15,962 $ 5,416 Undistributed (loss) earnings allocation - basic and diluted: Class A undistributed (loss) earnings $ (11,930 ) $ 2,809 $ 970 Class B undistributed (loss) earnings (56,154 ) 13,153 4,446 Total undistributed (loss) earnings $ (68,084 ) $ 15,962 $ 5,416 Net (loss) earnings allocation - basic and diluted: Class A net (loss) earnings $ (11,408 ) $ 3,331 $ 1,492 Class B net (loss) earnings (53,426 ) 15,866 7,111 Net (loss) earnings $ (64,834 ) $ 19,197 $ 8,603 Denominator: Weighted average shares outstanding: Class A - basic and diluted 2,175 2,175 2,175 Class B - basic and diluted 9,749 9,698 9,491 Net (loss) earnings per share: Class A - basic and diluted $ (5.25 ) $ 1.53 $ 0.69 Class B - basic and diluted $ (5.48 ) $ 1.64 $ 0.75 Research and Development ("R&D") - Our engineering groups are strategically located around the world to facilitate communication with and access to customers' engineering personnel. This collaborative approach enables partnerships with customers for technical development efforts. On occasion, we execute non-disclosure agreements with our customers to help develop proprietary, next generation products destined for rapid deployment. R&D costs are expensed as incurred, and are included in cost of sales on the consolidated statements of operations. Generally, R&D is performed internally for the benefit of the Company. R&D costs include salaries, building maintenance and utilities, rents, materials, administration costs and miscellaneous other items. R&D expenses for the years ended December 31, 2016, 2015 and 2014 amounted to $26.7 million, $27.7 million and $21.5 million, respectively. Fair Value Measurements Level 1 Level 2 Level 3 For financial instruments such as cash and cash equivalents, accounts receivable, accounts payable, accrued expenses and notes payable, the carrying amount approximates fair value because of the short maturities of such instruments. See Note 5, "Fair Value Measurements," for additional disclosures related to fair value measurements. Recently Issued Accounting Standards Recently Adopted Accounting Standards In June 2014, the FASB issued ASU 2014-12, Compensation – Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period . The amendment requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition.

ACQUISITIONS AND DISPOSITION [Abstract]
ACQUISITIONS AND DISPOSITION	2. ACQUISITIONS AND DISPOSITION 2014 Acquisitions On June 19, 2014, the Company completed its acquisition of Power Solutions for $109.9 million, net of cash acquired. Power Solutions is a leading provider of high-efficiency and high-density power conversion products for server, storage and networking equipment, industrial applications and power systems. In connection with its acquisition of Power Solutions from ABB Ltd., the Company acquired a 49% interest in a joint venture in the People's Republic of China ("PRC"). The Company has assigned no value to this investment. See Note 18, "Related Party Transactions," for additional information. At the conclusion of the measurement period, which was one year after the acquisition date, there were certain working capital and tax related items outstanding with ABB Ltd. The working capital item was settled with ABB Ltd. during the third quarter of 2015, which was after the conclusion of the measurement period and, as a result, the Company recognized $4.2 million of other income on the consolidated statements of operations. See Note 9, "Income Taxes," for further information on the tax related items outstanding with ABB Ltd. On July 25, 2014, the Company completed its acquisition of the U.S. and U.K. entities of Connectivity Solutions. On August 29, 2014, the China portion of the transaction closed. The Company paid a total of $98.8 million for Connectivity Solutions, net of cash acquired and including a working capital adjustment. Connectivity Solutions is a leading provider of high‑performance RF/Microwave and Harsh Environment Optical Connectors and Assemblies for military, aerospace, wireless communications, data communications, broadcast and industrial applications. During the years ended December 31, 2015 and 2014, the Company incurred $0.6 million and $7.3 million of acquisition-related costs, respectively, associated with the 2014 Acquisitions primarily for audit-related costs, investment banker fees and legal fees. These costs are included in selling, general and administrative expenses on the consolidated statements of operations. The purchase accounting related to the 2014 Acquisitions was finalized within one year of the respective acquisition dates. The results of operations of the 2014 Acquired Companies have been included in the Company's consolidated financial statements for the period subsequent to their respective acquisition dates. During the years ended December 31, 2016, 2015 and 2014, the 2014 Acquired Companies contributed revenue of $195.6 million, $230.3 million and $134.3 million, respectively, and operating income (loss) of approximately $3.8 million, $10.3 million and ($2.5) million, respectively, to the Company's consolidated financial results. The following unaudited pro forma information presents a summary of the combined results of operations of the Company and the aggregate results of Power Solutions and Connectivity Solutions for the periods presented as if the 2014 Acquisitions had occurred on January 1, 2013, along with certain pro forma adjustments. These pro forma adjustments give effect to the amortization of certain definite-lived intangible assets, adjusted depreciation based upon estimated fair value of assets acquired, interest expense and amortization of deferred financing costs related to the financing of the business combinations, and related tax effects. The 2014 unaudited pro forma net earnings for the year ended December 31, 2014 were adjusted to exclude $14.9 million ($9.8 million after tax) of non-recurring expenses, including audit, legal and other transaction fees, IT migration costs and employee-related expenses, which were incurred in connection with the 2014 Acquisitions. The pro forma results do not reflect the realization of any potential cost savings, or any related integration costs. Certain cost savings may result from these acquisitions; however, there can be no assurance that these cost savings will be achieved. The unaudited pro forma results are presented for illustrative purposes only and are not necessarily indicative of the results that would have actually been obtained if the acquisitions had occurred on the assumed dates, nor is the pro forma data intended to be a projection of results that may be obtained in the future. Year Ended December 31, 2014 Revenue $ 629,132 Net earnings 11,705 Earnings per Class A common share - basic and diluted 0.94 Earnings per Class B common share - basic and diluted 1.02 Disposition – Sale of NPS On January 23, 2015, the Company completed the sale of the Network Power Systems ("NPS") product line and related transactions of the acquired Power Solutions business to Unipower LLC ("Unipower") for $9.0 million in cash. The sale also included $1.0 million of escrow pending Unipower's realization of certain sales targets. The net proceeds of $9.0 million from the sale were used to repay outstanding borrowings in accordance with the provisions of the Credit and Security Agreement (see Note 10, Debt). The transaction provided that Bel would move processes and people to Unipower under an interim transition services agreement and that Bel would also continue to manufacture the NPS products for up to 24 months under a manufacturing services agreement. As a result of the sale and related transactions, the Company recorded deferred revenue of $9.0 million. Of this amount, the Company has recognized net sales of $4.5 million during each of 2016 and 2015. None of the $1.0 million of escrow was recognized as Unipower did not achieve the sales targets specified in the agreement. In January 2017, the Company extended the manufacturing services agreement with Unipower through June 2017 at renegotiated pricing by product for that term.

GOODWILL AND OTHER INTANGIBLE ASSETS [Abstract]
GOODWILL AND OTHER INTANGIBLE ASSETS	4. GOODWILL AND OTHER INTANGIBLE ASSETS Goodwill Goodwill represents the excess of the purchase price and related acquisition costs over the fair value assigned to the net tangible and other intangible assets acquired in a business acquisition. The changes in the carrying value of goodwill classified by our segment reporting structure for the years ended December 31, 2016 and 2015 are as follows: Total North America Asia Europe Balance at January 1, 2015 Goodwill, gross 145,310 69,380 50,052 25,878 Accumulated impairment charges (26,941 ) (14,066 ) (12,875 ) - Goodwill, net $ 118,369 $ 55,314 $ 37,177 $ 25,878 Measurement period adjustments 4,590 (6,016 ) 4,351 6,255 Foreign currency translation (1,325 ) - 129 (1,454 ) Balance at December 31, 2015: Goodwill, gross 148,575 63,364 54,532 30,679 Accumulated impairment charges (26,941 ) (14,066 ) (12,875 ) - Goodwill, net $ 121,634 $ 49,298 $ 41,657 $ 30,679 Impairment charge (101,650 ) (40,408 ) (41,633 ) (19,609 ) Foreign currency translation (2,033 ) - (24 ) (2,009 ) Balance at December 31, 2016: Goodwill, gross 146,542 63,364 54,508 28,670 Accumulated impairment charges (128,591 ) (54,474 ) (54,508 ) (19,609 ) Goodwill, net $ 17,951 $ 8,890 $ - $ 9,061 The goodwill associated with the 2014 acquisitions, as well as the allocation by reporting unit, was finalized by the end of each of the respective measurement periods in 2015, and resulted in an additional $4.6 million of goodwill being recorded in 2015. As discussed in Note 5, Fair Value Measurements, goodwill is reviewed for impairment on a reporting unit basis annually during the fourth quarter of each year and whenever events or changes in circumstances indicate the carrying value of goodwill may not be recoverable. The goodwill impairment test involves a two-step process. In the first step, the fair value of each reporting unit is compared to its carrying value. If the fair value of the reporting unit exceeds its carrying value, goodwill is not impaired and no further testing is required. If the fair value of the reporting unit is less than the carrying value, the second step of the impairment test must be performed to measure the amount of impairment loss. In the second step, the reporting unit's fair value is allocated to all of the assets and liabilities of the reporting unit, including any unrecognized intangible assets, in a hypothetical analysis that calculates the implied fair value of goodwill in the same manner as if the reporting unit was being acquired in a business combination. If the implied fair value of the reporting unit's goodwill is less than the carrying value, the difference is recorded as an impairment loss and a reduction to goodwill. We estimated the fair value of these reporting units using a weighting of fair values derived from income and market approaches. Under the income approach, we determine the fair value of a reporting unit based on the present value of estimated future cash flows. Cash flow projections are based on management's estimates of revenue growth rates and operating margins, taking into consideration industry and market conditions. The discount rate used is based on a weighted average cost of capital adjusted for the relevant risk associated with the characteristics of the business and the projected cash flows. The market approach estimates fair value based on market multiples of revenue and earnings derived from comparable publicly traded companies with similar operating and investment characteristics as the reporting unit. 2016 Annual Impairment Test During the fourth quarter of 2016, the Company completed step one of our annual goodwill impairment test for our reporting units. We concluded that the fair value of each of the Company's reporting units exceeded the respective carrying values and that there was no indication of impairment. The excess of estimated fair values over carrying value, including goodwill for each of our reporting units that had goodwill as of the 2016 annual impairment test were as follows: Reporting Unit % by Which Estimated Fair Value Exceeds Carrying Value North America 13% Europe 30% 2016 Interim Impairment Test During the first quarter of 2016, management determined that sufficient indicators of potential impairment existed to require an interim goodwill impairment analysis for all of the Company's reporting units. These indicators included the recent business performance of those reporting units, combined with the long-term market conditions and business trends within the reporting units. Detailed below is a table of key underlying assumptions utilized in the Level 3 fair value estimate calculation for the interim test performed as of March 31, 2016 as compared to those assumptions utilized during the annual valuation performed as of October 1, 2015. Assumptions may vary by reporting unit. The table below shows the range of assumptions utilized across the various reporting units. Goodwill Impairment Analysis Key Assumptions 2016 - Interim 2015 - Annual Income Approach - Discounted Cash Flows (a): Revenue 5-year compound annual growth rate (CAGR) (9.0%) - (0.6%) 2.6% - 2.7% 2016 EBITDA margins (b) 5.1% - 6.6% 7.2% - 8.4% Cost of equity capital 11.6% - 14.7% 12.3% - 16.5% Cost of debt capital 3.6% - 8.5% 2.4% - 5.9% Weighted average cost of capital 10.0% - 14.0% 11.0% - 15.0% Market Approach - Multiples of Guideline Companies (a): Net operating revenue multiples used 0.4 - 0.6 0.4 - 0.5 Operating EBITDA multiples used (b) 5.9 - 6.3 5.0 - 5.3 Invested capital control premium 25% 25% Weighting of Valuation Methods: Income Approach - Discounted Cash Flows 75% 75% Market Approach - Multiples of Guideline Companies 25% 25% (a) Ranges noted reflect assumptions and multiples used throughout the North America, Asia and Europe reporting units (b) EBITDA represents earnings before interest, taxes, depreciation and amortization. EBITDA margin is calculated by dividing EBITDA by net sales. The March 31, 2016 interim impairment test related to the Company's goodwill was performed by reporting unit (North America, Asia and Europe). The valuation test, which heavily weights future discounted cash flow projections, indicated impairment of the goodwill associated with all three of the Company's reporting units. As a result, the Company recorded a provisional non-cash goodwill impairment charges totaling $104.3 million during the first quarter of 2016. During the second quarter of 2016, the Company finalized its interim impairment test, which resulted in a $2.6 million reduction to the provisional impairment charge recorded during the first quarter of 2016. The Company's goodwill associated with its reporting units originated from several of Bel's prior acquisitions, primarily Power Solutions acquired in 2014 and Connectivity Solutions acquired in 2014 (which represented $55.5 million and $55.0 million, respectively, of the carrying value of goodwill at the testing date). The carrying value of the Company's goodwill was $121.6 million at December 31, 2015. As noted above, the fair value determined under step one of the goodwill impairment test completed in the fourth quarter of 2016 exceeded the carrying value for each reporting unit. Therefore, there was no impairment of goodwill. However, if the fair value decreases in future periods, the Company may fail step one of the goodwill impairment test and be required to perform step two. In performing step two, the fair value would have to be allocated to all of the assets and liabilities of the reporting unit. Therefore, any potential goodwill impairment charge would be dependent upon the estimated fair value of the reporting unit at that time and the outcome of step two of the impairment test. The fair values of the assets and liabilities of the reporting unit, including the intangible assets, could vary depending on various factors. The future occurrence of a potential indicator of impairment, such as a decrease in expected net earnings, adverse equity market conditions, a decline in current market multiples, a decline in our common stock price, a significant adverse change in legal factors or business climates, an adverse action or assessment by a regulator, unanticipated competition, strategic decisions made in response to economic or competitive conditions, or a more-likely-than-not expectation that a reporting unit or a significant portion of a reporting unit will be sold or disposed of, could require an interim assessment for some or all of the reporting units before the next required annual assessment. In the event of significant adverse changes of the nature described above, it may be necessary for us to recognize an additional non-cash impairment of goodwill, which could have a material adverse effect on our consolidated financial condition and results of operations. Based on annual impairment tests performed in prior years, there was no indication of goodwill impairment during 2014 or 2015. Other Intangible Assets Other identifiable intangible assets include patents, technology, license agreements, non-compete agreements and trademarks. Amounts assigned to these intangible assets have been determined by management. Management considered a number of factors in determining the allocations, including valuations and independent appraisals. Trademarks have indefinite lives and are reviewed for impairment on an annual basis. Other intangible assets, excluding trademarks, are being amortized over 1 to 29 years. The Company tests indefinite-lived intangible assets for impairment using a fair value approach, the relief-from-royalty method (a form of the income approach). At December 31, 2016, the Company's indefinite-lived intangible assets related to the trademarks acquired in the Power Solutions, Connectivity Solutions, Cinch and Fibreco acquisitions. The components of definite and indefinite-lived intangible assets are as follows: December 31, 2016 December 31, 2015 Gross Carrying Accumulated Net Carrying Gross Carrying Accumulated Net Carrying Amount Amortization Amount Amount Amortization Amount Patents, licenses and technology $ 38,658 $ 11,276 $ 27,382 $ 39,388 $ 7,932 $ 31,456 Customer relationships 43,821 8,302 35,519 44,894 5,735 39,159 Non-compete agreements 2,667 2,376 291 2,753 1,838 915 Trademarks 11,677 41 11,636 16,338 41 16,297 $ 96,823 $ 21,995 $ 74,828 $ 103,373 $ 15,546 $ 87,827 Amortization expense was $7.0 million in each of 2016 and 2015 and $5.4 million in 2014. Estimated amortization expense for intangible assets for the next five years is as follows: December 31, Amortization Expense 2017 $ 6,521 2018 6,229 2019 6,229 2020 6,197 2021 6,196 2016 Annual Impairment Test The Company completed its annual indefinite-lived intangible assets impairment test during the fourth quarter of 2016, noting no further impairment. Management has concluded that the fair value of these trademarks exceeded the related carrying values at December 31, 2016 and that there was no indication of impairment. 2016 Interim Impairment Test During the first quarter of 2016, management determined that sufficient indicators of potential impairment existed to require an interim impairment review of our trademarks. Based on the Company's analysis, the fair values of all of the Company's trademarks were lower than the respective carrying values. As a result, in 2016, the Company recorded a non-cash impairment of $4.3 million which is included in impairment of goodwill and other intangible assets on the consolidated statements of operations. Detailed below is a table of key underlying assumptions utilized in the Level 3 fair value estimate calculation of the Company's trademarks for the interim test performed as of March 31, 2016 as compared to those assumptions utilized during the annual valuation performed as of October 1, 2015. Assumptions may vary by individual trademark. The table below shows the range of assumptions utilized across the Company's various trademarks. Trademark Impairment Analysis Key Assumptions 2016 - Interim 2015 - Annual Revenue 5-year compound annual growth rate (CAGR) (0.4%) - 2.7% 0.2% - 4.0% Estimated fair royalty rate 0.25% - 1.5% 0.5% - 2.0% Discount rate 11.0% - 15.0% 12.0% - 14.0% Based on annual impairment tests performed in prior years, there was no indication of indefinite-lived intangible assets impairment during 2014 or 2015. The future occurrence of a potential indicator of impairment, such as those described above, could require an interim assessment for some or all of the Company's trademarks. In such a case, it may be necessary for us to recognize an additional non-cash impairment charge related to our trademarks, which could have a material adverse effect on our consolidated financial condition and results of operations.

FAIR VALUE MEASUREMENTS [Abstract]
FAIR VALUE MEASUREMENTS	5. FAIR VALUE MEASUREMENTS As of December 31, 2016 and 2015, 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, and other marketable securities described below. The securities that are held in the rabbi trust are categorized as available-for-sale securities and are included as other assets in the accompanying consolidated balance sheets at December 31, 2016 and 2015. The gross unrealized gains associated with the investments held in the rabbi trust were $0.7 million and $0.7 million at December 31, 2016 and 2015, respectively. Such unrealized gains are included, net of tax, in accumulated other comprehensive income. As of December 31, 2016 and 2015, our available-for-sale securities, which primarily consist of investments held in a rabbi trust of $1.7 million and $3.6 million, respectively, are 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 2016 or 2015. There were no changes to the Company's valuation techniques used to measure asset fair values on a recurring or nonrecurring basis during 2016. There were no financial assets accounted for at fair value on a nonrecurring basis as of December 31, 2016 or 2015. 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 December 31, 2016 and 2015, the estimated fair value of total debt was $144.3 million and $188.1 million, respectively, compared to a carrying amount of $141.2 million and $183.5 million, respectively. The Company did not have any other financial liabilities within the scope of the fair value disclosure requirements as of December 31, 2016. 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. See Note 4, "Goodwill and Other Intangible Assets," for further information about goodwill and other indefinite-lived intangible assets.

OTHER ASSETS

OTHER ASSETS [Abstract]
OTHER ASSETS	6. OTHER ASSETS At December 31, 2016 and 2015, the Company has obligations of $16.9 million and $15.6 million, respectively, associated with its SERP. As a means of informally funding these obligations, the Company has invested in life insurance policies related to certain employees and marketable securities held in a rabbi trust. At December 31, 2016 and 2015, these assets had a combined value of $12.7 million and $12.2 million, respectively. Company-Owned Life Insurance Investments in company-owned life insurance policies ("COLI") were made with the intention of utilizing them as a long-term funding source for the Company's SERP obligations. However, the cash surrender value of the COLI does not represent a committed funding source for these obligations. Any proceeds from these policies are subject to claims from creditors. The cash surrender value of the COLI of $10.9 million and $8.5 million at December 31, 2016 and 2015, respectively, is included in other assets in the accompanying consolidated balance sheets. During 2016 and 2015, the Company sold $2.2 million and $2.8 million, respectively, of marketable securities within the rabbi trust and utilized the proceeds to purchase additional COLI. The volatility in global equity markets in recent years has also had an effect on the cash surrender value of the COLI policies. The Company recorded income (expense) to account for the increase (decrease) in cash surrender value in the amount of $0.5 million, ($0.1) million and $0.2 million during the years ended December 31, 2016, 2015 and 2014, respectively. These fluctuations in the cash surrender value were allocated between cost of sales and selling, general and administrative expenses on the consolidated statements of operations for the years ended December 31, 2016, 2015 and 2014. The allocation is consistent with the costs associated with the long-term employee benefit obligations that the COLI is intended to fund. Other Investments At December 31, 2016 and 2015, the Company held, in the aforementioned rabbi trust, available-for-sale investments at a cost of $1.0 million and $2.9 million, respectively. Together with the COLI described above, these investments are intended to fund the Company's SERP obligations and are classified as other assets in the accompanying consolidated balance sheets. The Company monitors these investments for impairment on an ongoing basis. As discussed above, the Company sold $2.2 million of its SERP investments during 2016 and $2.8 million during 2015. At December 31, 2016 and 2015, the fair market value of these investments was $1.7 million and $3.6 million, respectively. The gross unrealized gain of $0.7 million and $0.7 million at December 31, 2016 and 2015, respectively, has been included, net of tax, in accumulated other comprehensive income (loss).

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 2013 and for state examinations before 2010. Regarding foreign subsidiaries, the Company is no longer subject to examination by tax authorities for years before 2006 in Asia and generally 2009 in Europe. At December 31, 2015, the Company was under examination by the taxing authorities in Germany for the tax years 2011 through 2013. This audit concluded in April 2016 and resulted in an immaterial amount of incremental tax expense. At December 31, 2016 and 2015, the Company has approximately $27.8 million and $42.2 million, respectively, of liabilities for uncertain tax positions ($0.4 million and $1.9 million, respectively, is included in other current liabilities on the consolidated balance sheets and $27.4 million and $40.3 million, respectively, is included in liability for uncertain tax positions on the consolidated balance sheets). These amounts, if recognized, would reduce the Company's effective tax rate. As of December 31, 2016, approximately $0.4 In connection with the acquisition of the Power Solutions business in 2014, the Company acquired a liability for additional uncertain tax positions related to various tax matters for the years 2007 through 2013. During the year ended December 31, 2016, a portion of these tax matters was resolved with the taxing authorities which resulted in a reduction of $13.9 million in the liability for uncertain tax positions, of which $11.1 million related to interest and penalties. The Company is actively pursuing resolution of the remaining tax matters. From the date of acquisition through December 31, 2016, the Company has recorded $4.5 million of interest and penalties pertaining to this issue, of which $2.6 million was reversed during 2016 in relation to the settlement of the exposure. The Company will continue to accrue approximately $ million annually until the issues are resolved. As part of the acquisition of Power Solutions, the Company acquired a $12.0 million liability for uncertain tax positions relating to 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.) for the years 2004 through 2006, as further described in Note 16, "Commitments and Contingencies." 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 December 31, 2016. A total of $0.4 million of the acquired liability for uncertain tax positions relates to the 2006 tax year and is scheduled to expire on December 31, 2017. Additionally, A reconciliation of the beginning and ending amount of the liability for uncertain tax positions, including the portion included in income taxes payable, is as follows : 2016 2015 2014 Liability for uncertain tax positions - January 1 $ 42,158 $ 39,970 $ 2,189 Additions based on tax positions related to the current year 2,483 3,241 2,732 Additions relating to acquisitions - - 35,874 Translation adjustment (881 ) (844 ) - Settlement/expiration of statutes of limitations (15,932 ) (209 ) (825 ) Liability for uncertain tax positions - December 31 $ 27,828 $ 42,158 $ 39,970 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 years ended December 31, 2016, 2015 and 2014, the Company recognized $1.3 million, $2.5 million and $1.6 million, respectively, in interest and penalties in the consolidated statements of operations. During the years ended December 31, 2016, 2015 and 2014, the Company recognized a benefit of $3.1 million, less than $0.1 million and $0.2 million, respectively, for the reversal of such interest and penalties, relating to the expiration of statues of limitations and settlement of the acquired liability for uncertain tax positions, respectively. The Company has approximately $2.2 million and $4.0 million accrued for the payment of interest and penalties at December 31, 2016 and 2015, respectively, which is included in both income taxes payable and liability for uncertain tax positions in the consolidated balance sheets. The Company's total (loss) earnings before (benefit) provision for income taxes included (loss) earnings from domestic operations of ($43.3) million, $6.1 million and ($9.2) million for 2016, 2015 and 2014, respectively, and (loss) earnings before (benefit) provision for income taxes from foreign operations of ($39.2) million, $19.6 million and $19.0 million for 2016, 2015 and 2014, respectively.

With this license, a Macao offshore company named Bel Fuse (Macao Commercial Offshore) Limited has been established to handle the Company's sales to third-party customers in Asia. Sales by this company consist of products manufactured in the PRC. This company is not subject to Macao corporate profit taxes which are imposed at a tax rate of 12%. Additionally, the Company established TRP International, a China Business Trust ("CBT"), when it acquired the TRP group, as previously discussed. Sales by the CBT consists of products manufactured in the PRC and sold to third-party customers inside and outside Asia. The CBT is not subject to PRC income taxes, which are generally imposed at a tax rate of 25%. As of December 31, 2016, the Company has gross foreign income tax net operating losses ("NOL") of $25.6 million, foreign tax credits of $0.3 million and capital loss carryforwards of $0.2 million which amount to a total of $6.2 million of deferred tax assets. The Company has established valuation allowances totaling $6.1million against these deferred tax assets. In addition, the Company has gross federal and state income tax NOLs of $16.0 million, including $3.8 million of NOLs acquired from Array and $10.0 million of NOLs acquired from Connectivity Solutions, which amount to $5.3 million of deferred tax assets and tax credit carryforwards of $2.3 million. The Company has established valuation allowances of $0.2 million and $1.2 million, respectively, against these deferred tax assets. The foreign NOL's can be carried forward indefinitely, the NOL acquired from Array expires at various times during 2026 – 2027, the NOL acquired from Connectivity Solutions expire at various times during 2022-2033, the state NOL's expire at various times during – 2031 and the tax credit carryforwards expire at various times during 2025 - 2034. It is the Company's intention to repatriate substantially all net income from its wholly owned PRC subsidiary, Dongguan Transpower Electric Products Co., Ltd, a Chinese Limited Liability Company, to its direct Hong Kong parent Transpower Technologies (Hong Kong) Ltd. Applicable income and dividend withholding taxes have been reflected in the accompanying consolidated statements of operations for the year ended December 31, 2016. However, U.S. deferred taxes need not be provided as there is no intention to repatriate such amounts to the U.S. Management's intention is to permanently reinvest the majority of the remaining earnings of foreign subsidiaries in the expansion of its foreign operations. Unrepatriated earnings, upon which U.S. income taxes have not been accrued, are approximately $100.4 million at December 31, 2016. Such unrepatriated earnings are deemed by management to be permanently reinvested. At December 31, 2016, the estimated federal income tax liability related to unrepatriated foreign earnings is $23.3 million under the current tax law.

DEBT [Abstract]
DEBT	10. DEBT On June 19, 2014, the Company entered into a senior Credit and Security Agreement with KeyBank National Association ("KeyBank"), as administrative agent and lender, which was amended on June 30, 2014 principally to add a syndicate of additional lenders (as so amended, the "Credit and Security Agreement" or "CSA"). The maturity date of the CSA is June 18, 2019. The CSA consists of (i) a $50 million revolving credit facility ("Revolver"), (ii) a $145 million term loan facility ("Term Loan") and (iii) a $70 million delayed draw term loan ("DDTL"). Under the terms of the CSA, the Company is entitled, subject to the satisfaction of certain conditions, to request additional commitments under the revolving credit facility or term loans in the aggregate principal amount of up to $100 million to the extent that existing or new lenders agree to provide such additional commitments and/or term loans. The obligations of the Company under the CSA are guaranteed by certain of the Company's material U.S. subsidiaries (together with the Company, the "Loan Parties") and are secured by a first priority security interest in substantially all of the existing and future personal property of the Loan Parties, certain material real property of the Loan Parties and certain of the Loan Parties' material U.S. subsidiaries, including 65% of the voting capital stock of certain of the Loan Parties' direct foreign subsidiaries. The borrowings under the CSA will bear interest at a rate equal to, at the Company's option, either (1) LIBOR, plus a margin ranging from 1.75% per annum to 3.00% per annum depending on the Company's leverage ratio, or (2)(a) an "Alternate Base Rate," which is the highest of (i) the federal funds rate plus 0.50%, (ii) KeyBank's prime rate and (iii) the LIBOR rate with a maturity of one month plus 1.00%, plus (b) a margin ranging from 0.75% per annum to 2.00% per annum, depending on the Company's leverage ratio. The interest rate in effect at December 31, 2016 was 3.06%, which consisted of LIBOR of 0.81% plus the Company's margin of 2.25%. The interest rate in effect at December 31, 2015 was 3.19%, which consisted of LIBOR of 0.44% plus the Company's margin of 2.75%. 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 ("Fixed Charge Coverage Ratio"). 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 December 31, 2016, the Company was in compliance with its debt covenants, including its most restrictive covenant, the Leverage Ratio. The unused credit available under the credit facility at December 31, 2016 was $50.0 million. In January 2017, the Company borrowed $6.0 million of its available credit under the credit facility. Concurrent with its entry into the CSA on June 19, 2014, the Company borrowed $145.0 million under the Term Loan to complete its acquisition of Power Solutions. In July 2014, in connection with the acquisition of Connectivity Solutions, the Company borrowed an additional $90.0 million under the CSA ($70.0 million through the DDTL and $20.0 million under the Revolver). In March 2016, the Company amended the terms of the CSA to modify (i) the date by which the Company was obligated to make excess cash flow prepayments in 2016 on account of excess cash flow achieved for fiscal year 2015, (ii) the method of application of mandatory and voluntary prepayments related to the Company's loans, and (iii) the maximum Leverage Ratio of the Company allowed under the CSA for the period from the effective date of the amendment through September 2017. In connection with this amendment to the CSA, the Company paid $0.7 million of deferred financing costs, and the modification to the amortization schedule resulted in $0.5 million of existing deferred financing costs to be accelerated and recorded as interest expense during the first quarter of 2016. The Company recorded a total of $6.5 million in deferred financing costs related to the CSA since 2014, and these costs are being amortized in interest expense over the remaining term of the loan. At December 31, 2016 and 2015, the carrying value of the debt on the consolidated balance sheets is reflected net of $2.6 million and $3.6 million, respectively, of deferred financing costs as a result of the adoption of accounting guidance effective January 1, 2016. See Note 1, "Basis of Presentation and Accounting Policies". In connection with its outstanding borrowings and amortization of the deferred financing costs described above, the Company incurred $6.7 million and $7.6 million of interest expense during the years ended December 31, 2016 and 2015, respectively. At December 31, 2016 and 2015, borrowings outstanding related to the term loans (Term Loan and DDTL combined) were $143.8 million and $187.2 million, respectively, with no borrowings outstanding under the revolver at either period. Scheduled principal payments of the total debt outstanding at December 31, 2016 are as follows (in thousands): 2017 $ 12,495 2018 20,860 2019 110,443 Total long-term debt 143,798 Less: Current maturities of long-term debt (12,495 ) Noncurrent portion of long-term debt $ 131,303

Management cannot presently predict what future impact this will have on the Company, if any, or how the political climate in the PRC will affect the Company's contractual arrangements in the PRC. A significant portion of the Company's manufacturing operations and approximately 40% of its identifiable assets are located in Asia. Net Sales to Major Customers The Company had net sales to one customer in excess of ten percent of consolidated net sales in each of 2016, 2015 and 2014. The net sales associated with this customer was $59.8 million in 2016 (12.0% of sales), $74.8 million in 2015 (13.2% of sales) and $76.4 million in 2014 (15.7% of sales).

RETIREMENT FUND AND PROFIT SHARING PLAN [Abstract]
RETIREMENT FUND AND PROFIT SHARING PLAN	13. RETIREMENT FUND AND PROFIT SHARING PLAN The Company maintains the Bel Fuse Inc. Employees' Savings Plan, a defined contribution plan that is intended to meet the applicable requirements for tax-qualification under sections 401(a) and (k) of the Internal Revenue Code of 1986, as amended (the "Code"). The Employees' Savings Plan allows eligible employees to voluntarily contribute a percentage of their eligible compensation, subject to Code limitations, which contributions are matched by the Company. For plan years beginning on and after January 1, 2012, the Company's matching contributions are made in cash and are equal to 100% of the first 1% of compensation contributed by participants, and 50% of the next 5% of compensation contributed by participants. Prior to January 1, 2012, the Company's matching and profit sharing contributions were made in the form of shares of Bel Fuse Inc. Class A and Class B common stock. The expense for the years ended December 31, 2016, 2015 and 2014 amounted to $1.1 million, $1.2 million and $0.8 million, respectively. As of December 31, 2016, the plan owned 13,637 and 159,688 shares of Bel Fuse Inc. Class A and Class B common stock, respectively. Effective January 1, 2017, the Company's matching contribution will be made in the form of Bel Fuse Inc. Class A common stock. The Company's subsidiaries in Asia have a retirement fund covering substantially all of their Hong Kong based full-time employees. Eligible employees contribute up to 5% of salary to the fund. In addition, the Company must contribute a minimum of 5% of eligible salary, as determined by Hong Kong government regulations. The Company currently contributes 7% of eligible salary in cash or Company stock. The expense for the years ended December 31, 2016, 2015 and 2014 amounted to approximately $0.3 million in each year. As of December 31, 2016, the plan owned 3,323 and 17,342 shares of Bel Fuse Inc. Class A and Class B common stock, respectively. The Company maintains a SERP, which is designed to provide a limited group of key management and other key employees of the Company supplemental retirement and death benefits. . The SERP initially became effective in The Plan is unfunded. Benefits under the SERP are payable from the general assets of the Company, but the Company has established a rabbi trust which includes certain life insurance policies in effect on participants as well as other investments to partially cover the Company's obligations under the Plan. See Note 6, "Other Assets," for further information on these assets. The benefits available under the Plan vary according to when and how the participant terminates employment with the Company. If a participant retires (with the prior written consent of the Company) on his normal retirement date (65 years old, 20 years of service, and 5 years of Plan participation), his normal retirement benefit under the Plan would be annual payments equal to 40% of his average base compensation (calculated using compensation from the highest five consecutive calendar years of Plan participation), payable in monthly installments for the remainder of his life. If a participant retires early from the Company (55 years old, 20 years of service, and five years of Plan participation), his early retirement benefit under the Plan would be an amount (i) calculated as if his early retirement date were in fact his normal retirement date, (ii) multiplied by a fraction, with the numerator being the actual years of service the participant has with the Company and the denominator being the years of service the participant would have had if he had retired at age 65, and (iii) actuarially reduced to reflect the early retirement date. If a participant dies prior to receiving 120 monthly payments under the Plan, his beneficiary would be entitled to continue receiving benefits for the shorter of (i) the time necessary to complete 120 monthly payments or (ii) 60 months. If a participant dies while employed by the Company, his beneficiary would receive, as a survivor benefit, an annual amount equal to (i) 100% of the participant's annual base salary at date of death for one year, and (ii) 50% of the participant's annual base salary at date of death for each of the following four years, each payable in monthly installments. The Plan also provides for disability benefits, and a forfeiture of benefits if a participant terminates employment for reasons other than those contemplated under the Plan. The expense related to the Plan for the years ended December 31, 2016, 2015 and 2014 amounted to $1.6 million, $1.5 million and $1.3 million, respectively.

The accumulated benefit obligation for the SERP was $13.8 million as of December 31, 2016 and $12.7 million as of December 31, 2015. The estimated net loss and prior service cost for the defined benefit pension plan that will be amortized from accumulated other comprehensive loss into net periodic benefit cost over the next fiscal year is $0.4 million. The Company expects to make contributions of $0.1 million to the SERP in 2017. The Company had no net transition assets or obligations recognized as an adjustment to other comprehensive income and does not anticipate any plan assets being returned to the Company during 2017, as the plan has no assets.

SHARE-BASED COMPENSATION [Abstract]
SHARE-BASED COMPENSATION	14. SHARE-BASED COMPENSATION The Company has (the " ") which provides for the granting of "Incentive Stock Options" within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended The Company believes that such awards better align the interest of its employees with those of its shareholders. The 2011 Equity Compensation Plan provides for the issuance of 1.4 million shares of the Company's Class B common stock. At December 31, 2016, 599,800 shares remained available for future issuance under the 2011 Equity Compensation Plan. The Company records compensation expense in its consolidated statements of operations related to employee stock-based options and awards. The aggregate pretax compensation cost recognized for stock-based compensation amounted to approximately $2.8 million, $2.8 million and $2.7 million for 2016, 2015 and 2014, respectively, and related solely to restricted stock awards Restricted Stock Awards The Company provides common stock awards to certain officers and key employees. The Company grants these awards, at its discretion, from the shares available under the Program. Unless otherwise provided at the date of grant or unless subsequently accelerated, the shares awarded are typically earned in 25% increments on the second, third, fourth and fifth anniversaries of the award and are distributed provided the employee has remained employed by the Company through such anniversary dates; otherwise the unearned shares are forfeited. The market value of these shares at the date of award is recorded as compensation expense on the straight-line method over the five-year periods from the respective award dates, as adjusted for forfeitures of unvested awards. During 2016, 2015 and 2014, the Company issued 180,000 shares, 84,000 shares and 378,000 shares of the Company's Class B common stock, respectively, under a restricted stock plan to various officers and employees. A summary of the restricted stock activity under the Program as of December 31, 2016 is presented below: Weighted Average Restricted Stock Weighted Average Remaining Awards Shares Award Price Contractual Term Outstanding at January 1, 2016 564,025 $ 22.00 3.2 years Granted 180,000 23.30 Vested (155,100 ) 20.99 Forfeited (30,325 ) 23.06 Outstanding at December 31, 2016 558,600 $ 22.64 3.1 years As of December 31, 2016, there was $8.7 million of total pretax unrecognized compensation cost included within additional paid-in capital related to non-vested stock based compensation arrangements granted under the restricted stock award plan. That cost is expected to be recognized over a period of 4.9 years. This expense is recorded in cost of sales and SG&A expense based upon the employment classification of the award recipients. The Company's policy is to issue new shares to satisfy restricted stock awards. Currently the Company believes that substantially all restricted stock awards will vest.

COMMON STOCK

COMMON STOCK	12 Months Ended

COMMON STOCK [Abstract]
COMMON STOCK	15. COMMON STOCK As of December 31, 2016, according to regulatory filings, there was one shareholder of the Company's common stock (other than shareholders subject to specific exceptions) with ownership in excess of 10% of Class A outstanding shares with no ownership of the Company's Class B common stock. In accordance with the Company's certificate of incorporation, the Class B Protection clause is triggered if a shareholder owns 10% or more of the outstanding Class A common stock and does not own an equal or greater percentage of all then outstanding shares of both Class A and Class B common stock (all of which common stock must have been acquired after the date of the 1998 recapitalization). In such a circumstance, such shareholder must, within 90 days of the trigger date, purchase Class B common shares, in an amount and at a price determined in accordance with a formula described in the Company's certificate of incorporation, or forfeit its right to vote its Class A common shares. As of December 31, 2016, to the Company's knowledge, this shareholder had not purchased any Class B shares to comply with these requirements. In order to vote its shares at Bel's next shareholders' meeting, this shareholder must either purchase the required number of Class B common shares or sell or otherwise transfer Class A common shares until its Class A holdings are under 10%. As of December 31, 2016, to the Company's knowledge, this shareholder owned 23.15% of the Company's Class A common stock in the aggregate and had not taken steps to either purchase the required number of Class B common shares or sell or otherwise transfer Class A common shares until its Class A holdings fall below 10%. Unless and until this situation is satisfied in a manner permitted by the Company's Restated Certificate of Incorporation, the subject shareholder will not be permitted to vote its shares of common stock. Throughout 2016, 2015 and 2014, the Company declared cash dividends on a quarterly basis at a rate of $0.06 per Class A share of common stock and $0.07 per Class B share of common stock. The Company declared and paid cash dividends totaling $3.2 million in each of 2016, 2015 and 2014. There are no contractual restrictions on the Company's ability to pay dividends, provided that the Company is not in default under its credit agreements immediately before such payment and after giving effect to such payment.

COMMITMENTS AND CONTINGENCIES [Abstract]
COMMITMENTS AND CONTINGENCIES	16. COMMITMENTS AND CONTINGENCIES Leases The Company leases various facilities under operating leases expiring through December 2023. Some of these leases require the Company to pay certain executory costs (such as insurance and maintenance). Future minimum lease payments for operating leases are approximately as follows: Year Ending December 31, 2017 $ 6,491 2018 3,590 2019 2,813 2020 2,597 2021 2,108 Thereafter 1,171 $ 18,770 Rental expense for all leases was approximately $7.9 million, $8.8 million and $7.5 million for the years ended December 31, 2016, 2015 and 2014, respectively. Other Commitments The Company submits purchase orders for raw materials to various vendors throughout the year for current production requirements, as well as forecasted requirements. Certain of these purchase orders relate to special purpose material and, as such, the Company may incur penalties if an order is cancelled. The Company had outstanding purchase orders related to raw materials in the amount of $31.0 million and $42.6 million at December 31, 2016 and December 31, 2015, respectively. The Company also had outstanding purchase orders related to capital expenditures in the amount of $2.8 million and $1.5 million at December 31, 2016 and December 31, 2015, respectively. Legal Proceedings The Company was a defendant in a lawsuit captioned SynQor, Inc. v. Artesyn Technologies, Inc., et al. brought in the United States District Court for the Eastern District of Texas in September 2011. This was a patent infringement action for damages in the form of lost profits and reasonable royalties for the period beginning January 24, 2011 (the post-verdict period of a related case). SynQor, Inc. also sought enhanced damages. The Company had an indemnification agreement in place with one of its customers specifically covering post-verdict damages related to this case. This case went to trial on July 30, 2013. In April 2014, a final judgment was rendered in this case, whereby the Company was assessed an additional $0.7 million in post-verdict damages. This amount was paid by the Company in July 2014 and was subsequently reimbursed by one of its customers under the terms of the indemnification agreement referenced above. SynQor filed an appeal of the final judgment in May 2014. The appeals court heard oral arguments from the parties on this matter on March 2, 2015. The matter was settled as to all further damages and claims relating to the appeal in early 2016 with no further payment required from the Company. The Company is a plaintiff in a lawsuit captioned Bel Fuse Inc. et al. v. Molex Inc. brought in the United District Court of New Jersey in April 2013. The Company claims that Molex infringed three of the Company's patents related to integrated magnetic connector products. Molex filed a motion to dismiss the complaint on August 6, 2013. The Company filed an amended complaint and response on August 20, 2013. Molex withdrew its original Motion to Dismiss and filed a second, revised Motion to Dismiss on September 6, 2013. The Company filed its response on October 7, 2013. The Court denied Molex's revised Motion to Dismiss on June 16, 2014. In June 2014, Molex initiated an Inter Partes Review (IPR) at the U.S. Patent and Trademark Office for one of the three patents associated with this case. The Company and Molex executed an agreement in September 2014 to terminate the IPR and to withdraw one of the patents from the district court litigation. The Parties settled the case involving the two remaining patents for $0.5 million in September 2015 and the case was subsequently dismissed by the Court in October 2015. The Company recognized the settlement amount in net sales on the consolidated statements of operations. 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 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 December 31, 2016 and December 31, 2015. 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 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 is currently scheduled for March 23, 2017. The Company does not have enough information at this time in order to make any further conclusions or assessments as to infringement or potential damages. 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.

DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES [Abstract]
Principles of Consolidation	Principles of Consolidation -
Use of Estimates	Use of Estimates - to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an on-going basis, we evaluate our estimates, including but not limited to those related to product returns, provisions for bad debt, inventories, goodwill, intangible assets, investments, Supplemental Executive Retirement Plan ("SERP") expense, income taxes, contingencies and litigation. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.
Cash Equivalents	Cash Equivalents
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts
Effects of Foreign Currency	Effects of Foreign Currency – In non-U.S. locations that are not considered highly inflationary, we translate the balance sheets at the end of period exchange rates with translation adjustments accumulated within stockholders' equity on our consolidated balance sheets. We translate the statements of operations at the average exchange rates during the applicable period. In connection with foreign currency denominated transactions, including multi-currency intercompany payable and receivable transactions and loans, the Company incurred net realized and unrealized currency exchange gains of $3.1 million, $5.1 million and $4.3 million for the years ended December 31, 2016, 2015 and 2014, respectively, were included in SG&A expenses on the consolidated statements of operations.
Concentration of Credit Risk	Concentration of Credit Risk - We place temporary cash investments with quality financial institutions and commercial issuers of short-term paper and, by policy, limit the amount of credit exposure in any one financial
Inventories	Inventories
Revenue Recognition	Revenue Recognition For certain customers, we provide consigned inventory, either at the customer's facility or at a third-party warehouse. Sales of consigned inventory are recorded when the customer withdraws inventory from consignment . 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 these 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.
Product Warranties	Product Warranties
Goodwill and Identifiable Intangible Assets	Goodwill and Identifiable Intangible Assets Identifiable intangible assets consist primarily of patents, licenses, trademarks, trade names, customer lists and relationships, non-compete agreements and technology based intangibles and other contractual agreements. We amortize finite lived identifiable intangible assets over the shorter of their stated or statutory duration or their estimated useful lives, ranging from 1 to 29 years, on a straight-line basis to their estimated residual values and periodically review them for impairment. Total identifiable intangible assets comprise 17.5% and 15.2% in 2016 and 2015, respectively, of our consolidated total assets. We use the acquisition method of accounting for all business combinations and do not amortize goodwill or intangible assets with indefinite useful lives. Goodwill and intangible assets with indefinite useful lives are tested for possible impairment annually during the fourth quarter of each fiscal year or more frequently if events or changes in circumstances indicate that the asset might be impaired.
Impairment and Disposal of Long-Lived Assets	Impairment and Disposal of Long-Lived Assets For indefinite-lived intangible assets, such as trademarks and trade names, each year and whenever impairment indicators are present, we determine the fair value of the asset and record an impairment loss for the excess of book value over the fair value, if any. In addition, in all cases of an impairment review we re-evaluate whether continuing to characterize the asset as indefinite-lived is appropriate. See Note 4, "Goodwill and Other Intangible Assets," for additional details.
Depreciation	Depreciation -
Income Taxes	Income Taxes - We record net deferred tax assets to the extent we believe these assets will more-likely-than-not be realized. In making such determination, we consider all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax planning strategies and recent financial operations. We have established valuation allowances for deferred tax assets that are not likely to be realized. In the event we were to determine that we would be able to realize our deferred income tax assets in the future in excess of our net recorded amount, we would adjust the valuation allowance, which would reduce the provision for income taxes. We establish reserves for tax contingencies when, despite the belief that our tax return positions are fully supported, it is probable that certain positions may be challenged and may not be fully sustained. The tax contingency reserves are analyzed on a quarterly basis and adjusted based upon changes in facts and circumstances, such as the conclusion of federal and state audits, expiration of the statute of limitations for the assessment of tax, case law and emerging legislation. Our effective tax rate includes the effect of tax contingency reserves and changes to the reserves as considered appropriate by management.
Earnings per Share	Earnings per Share
Research and Development ("R&D")	Research and Development ("R&D") - Our engineering groups are strategically located around the world to facilitate communication with and access to customers' engineering personnel. This collaborative approach enables partnerships with customers for technical development efforts. On occasion, we execute non-disclosure agreements with our customers to help develop proprietary, next generation products destined for rapid deployment. R&D costs are expensed as incurred, and are included in cost of sales on the consolidated statements of operations. Generally, R&D is performed internally for the benefit of the Company. R&D costs include salaries, building maintenance and utilities, rents, materials, administration costs and miscellaneous other items. R&D expenses for the years ended December 31, 2016, 2015 and 2014 amounted to $26.7 million, $27.7 million and $21.5 million, respectively.
Fair Value Measurements	Fair Value Measurements Level 1 Level 2 Level 3 For financial instruments such as cash and cash equivalents, accounts receivable, accounts payable, accrued expenses and notes payable, the carrying amount approximates fair value because of the short maturities of such instruments. See Note 5, "Fair Value Measurements," for additional disclosures related to fair value measurements.
Recently Issued Accounting Standards	Recently Issued Accounting Standards Recently Adopted Accounting Standards In June 2014, the FASB issued ASU 2014-12, Compensation – Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period . The amendment requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. A reporting entity should apply existing guidance in Topic 718 as it relates to awards with performance conditions that affect vesting to account for such awards.

The Company currently plans to adopt this accounting standard in the first quarter of fiscal year 2018. The guidance permits two methods of adoption: full retrospective in which the standard is applied to all of the periods presented or modified retrospective where an entity will have to recognize the cumulative effect of initially applying the standard as an adjustment to the opening balance of retained earnings. We are currently evaluating the full impact of this new guidance on its consolidated financial statements, including selection of the transition method. The Company is still in the process of evaluating the effect of the new standard on the Company's historical financial statements. Our efforts to adopt this standard to date have focused on contract analysis at a business unit and regional level. As the Company completes its evaluation of this new standard, new information may arise that could change the Company's current understanding of the impact to revenue and expense recognized. Additionally, the Company will continue to monitor industry activities and any additional guidance provided by regulators, standards setters, or the accounting profession and adjust the Company's assessment and implementation plans accordingly.
