NATURE OF OPERATIONS AND BASIS

NATURE OF OPERATIONS AND BASIS OF PRESENTATION	3 Months Ended

Accounting Policies [Abstract]
NATURE OF OPERATIONS AND BASIS OF PRESENTATION	1. NATURE OF OPERATIONS AND BASIS OF PRESENTATION Nature of Operations CUI Global Inc. (CUI Global) is a platform company composed of two segments: the Power and Electromechanical segment and the Energy segment. The Power and Electromechanical segment is made up of the following wholly owned subsidiaries of CUI Global: CUI, Inc. (CUI), based in Tualatin, Oregon; CUI Japan, based in Tokyo, Japan; and CUI-Canada, based in Toronto, Canada. All three subsidiaries are providers of power and electromechanical components including power supplies, transformers, converters, connectors and industrial controls for Original Equipment Manufacturers (OEMs). The Power and Electromechanical segment defines its product offerings into two categories: components including connectors, speakers, buzzers, test and measurement devices, and control solutions including encoders and sensors; and power solutions, which includes Novum. These offerings provide a technology architecture that addresses power and related accessories to industries as broadly ranging as consumer electronics, medical and defense. The Company’s Energy segment is made up of the Orbital Gas Systems Limited subsidiary (Orbital) and the Orbital Gas Systems, North America, Inc. subsidiary. This business segment was formed when in April 2013, CUI Global acquired 100 CUI Properties, LLC owns the CUI Global headquarters facility located in Tualatin, Oregon and is included in the consolidation of the Company. Basis of Presentation The accompanying interim unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America and the rules and regulations of the United States Securities and Exchange Commission for interim financial information, which includes condensed consolidated financial statements. Accordingly, they do not include all the information and notes necessary for a comprehensive presentation of financial position and results of operations and should be read in conjunction with the Annual Report, Form 10-K for the year ended December 31, 2015. It is management's opinion that all material adjustments (consisting of normal recurring adjustments) have been made, which are necessary for a fair financial statement presentation. Significant intercompany accounts and transactions have been eliminated in consolidation. The results for the interim period are not necessarily indicative of the results to be expected for the year ending December 31, 2016. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Certain amounts from the prior periods have been reclassified to the current period presentation including on the condensed consolidated statements of operations, for the three months ended March 31, 2015, $ 33 , and $ 12 79 5 35 30 The following reclassifications were related to the third quarter 2015 reclassification of product certifications from property and equipment to other intangible assets: on the condensed consolidated statements of cash flows for the three months ended March 31, 2015, $42 thousand of depreciation expense was reclassified to amortization of intangibles, and $35 thousand of purchases of property and equipment was reclassified to investments in other intangible assets. Revisions The following immaterial revisions made to prior financial statements were related to sales of raw material components to a vendor that in turn, sold finished goods inventory to the Company that included the raw material components that we had sold to the vendor. For the three months ended March 31, 2015, sales and cost of sales were both decreased by $ 216 246 177

Goodwill and Intangible Assets Disclosure [Abstract]
GOODWILL AND INDEFINITE-LIVED INTANGIBLES	3. GOODWILL AND INDEFINITE-LIVED INTANGIBLES The Company tests for goodwill impairment in the second quarter of each year and whenever events or circumstances indicate that the carrying amount of the asset exceeds its fair value and may not be recoverable. In accordance with its policies, the Company performed a qualitative assessment of goodwill at May 31, 2015, and determined there was no impairment of goodwill. As detailed in ASC 350-20-35-3A, in performing its testing for impairment of goodwill, management completes a qualitative analysis to determine whether it was more likely than not that the fair value of a reporting unit is less than its carrying amount, including goodwill. To complete this review, management follows the steps in ASC 350-20-35-3C to evaluate the fair values of the goodwill and considers all known events and circumstances that might trigger an impairment of goodwill. Through these reviews, management concluded that there were no events or circumstances that triggered an impairment (and there was no expectation that a reporting unit or a significant portion of a reporting unit would be sold or otherwise disposed of in the following year), therefore, no further analysis was necessary to prepare for goodwill impairment beyond the steps in ASC 350-20-35-3C in accordance with ASU 2011-08.

The Company performed a qualitative assessment of impairment for other indefinite-lived assets at May 31, 2015 following the guidance in ASC 350-30-35-18A and 18B and determined there to be no impairment.

Earnings Per Share [Abstract]
LOSS PER COMMON SHARE	11. LOSS PER COMMON SHARE In accordance with FASB Accounting Standards Codification Topic 260 (“FASB ASC 260”), “Earnings per Share,” basic net income (loss) per share is computed by dividing the net income (loss) available to common stockholders for the period by the weighted average number of common shares outstanding during the period. Diluted net income (loss) per share is computed by dividing net income (loss) available to common stockholders by the weighted average number of diluted shares outstanding during the period calculated using the treasury stock method. Due to the Company’s net loss in the three months ended March 31, 2016 and March 31, 2015, the assumed exercise of stock options using the treasury stock method would have had an antidilutive effect and therefore 1.0 (in thousands except per share amount) For the three months ended 2016 2015 Net loss $ (2,668) $ (4,076) Basic and diluted weighted average number of shares outstanding 20,879 20,774 Basic and diluted loss per common share $ (0.13) $ (0.20)

NATURE OF OPERATIONS AND BASI28

NATURE OF OPERATIONS AND BASIS OF PRESENTATION (Policies)	3 Months Ended
	Mar. 31, 2016
Accounting Policies [Abstract]
Nature of Operations	Nature of Operations CUI Global Inc. (CUI Global) is a platform company composed of two segments: the Power and Electromechanical segment and the Energy segment. The Power and Electromechanical segment is made up of the following wholly owned subsidiaries of CUI Global: CUI, Inc. (CUI), based in Tualatin, Oregon; CUI Japan, based in Tokyo, Japan; and CUI-Canada, based in Toronto, Canada. All three subsidiaries are providers of power and electromechanical components including power supplies, transformers, converters, connectors and industrial controls for Original Equipment Manufacturers (OEMs). The Power and Electromechanical segment defines its product offerings into two categories: components including connectors, speakers, buzzers, test and measurement devices, and control solutions including encoders and sensors; and power solutions, which includes Novum. These offerings provide a technology architecture that addresses power and related accessories to industries as broadly ranging as consumer electronics, medical and defense. The Company’s Energy segment is made up of the Orbital Gas Systems Limited subsidiary (Orbital) and the Orbital Gas Systems, North America, Inc. subsidiary. This business segment was formed when in April 2013, CUI Global acquired 100 CUI Properties, LLC owns the CUI Global headquarters facility located in Tualatin, Oregon and is included in the consolidation of the Company.
Basis of Presentation	Basis of Presentation The accompanying interim unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America and the rules and regulations of the United States Securities and Exchange Commission for interim financial information, which includes condensed consolidated financial statements. Accordingly, they do not include all the information and notes necessary for a comprehensive presentation of financial position and results of operations and should be read in conjunction with the Annual Report, Form 10-K for the year ended December 31, 2015. It is management's opinion that all material adjustments (consisting of normal recurring adjustments) have been made, which are necessary for a fair financial statement presentation. Significant intercompany accounts and transactions have been eliminated in consolidation. The results for the interim period are not necessarily indicative of the results to be expected for the year ending December 31, 2016. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Reclassification	Certain amounts from the prior periods have been reclassified to the current period presentation including on the condensed consolidated statements of operations, for the three months ended March 31, 2015, $ 33 , and $ 12 79 5 35 30 The following reclassifications were related to the third quarter 2015 reclassification of product certifications from property and equipment to other intangible assets: on the condensed consolidated statements of cash flows for the three months ended March 31, 2015, $42 thousand of depreciation expense was reclassified to amortization of intangibles, and $35 thousand of purchases of property and equipment was reclassified to investments in other intangible assets.

[1]	On October 1, 2013, the funding of the purchase of the Company’s Tualatin, Oregon corporate offices from Barakel, LLC was completed. The purchase price for this asset was $5.1 million. The purchase was funded, in part, by a promissory note payable to Wells Fargo Bank in the amount of $3.7 million plus interest at the rate of 2% above LIBOR, payable over ten years with a balloon payment due at maturity. It was secured by a deed of trust on the purchased property which was executed by CUI Properties, LLC and guaranteed by CUI Global, Inc. During the three months ended March 31, 2016, the Company made principal payments of $21 thousand against the mortgage promissory note payable. At March 31, 2016, the balance owed on the mortgage promissory note payable was $3.5 million, of which $86 thousand and $3.4 million were in current and long-term liabilities, respectively.
[2]	The note payable to International Electronic Devices, Inc. (formerly CUI, Inc.) is associated with the acquisition of CUI, Inc. The promissory note is due May 15, 2020 and includes a 5% interest rate per annum, with interest payable monthly and the principal due as a balloon payment at maturity. The note contains a contingent conversion feature, such that in the event of default on the note the holder of the note can, at the holder’s option, convert the note principal into common stock at $0.001 per share. As of March 31, 2016, the Company is in compliance with all terms of this promissory note and the conversion feature is not effective.
