Significant Accounting Policies [Text Block]
2.
     SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
Use of Estimates
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. Significant estimates include estimates used to review the Company’s goodwill, impairments and estimations of long-lived assets, revenue recognition on cost-to-cost type contracts, allowances for uncollectible accounts, inventory valuation, warranty reserves, valuations of non-cash capital stock issuances and the valuation allowance on deferred tax assets. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable in 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.
 
Company Conditions
The continued delays in shipment of GasPTs on a significant project due to governmental delays and the related slower than expected acceptance of this new disruptive technology has caused a delay in our expected profitability.
 
The Company had losses of
$17.3
million and cash used in operating activities of
$12.3
million during the year ended
December 31, 2018.
As of
December 31, 2018,
our accumulated deficit is
$124.0
million.
 
Management believes the Company's present cash flows will
not
enable it to meet its obligations for
twelve
months from the date these financial statements are available to be issued. However, management has developed a plan to address this issue. The plan included obtaining a new long-term financing in the form of a new line of credit, and utilizing the cash received from our recent sale/leaseback of our Tualatin headquarters. As part of this plan the Company has obtained a firm commitment from Bank of American for a
$10.0
million credit facility. The new line of credit is expected to close in
April
of
2019.
For more information on the Company's new line of credit, see Note
16
Subsequent Events. In addition, as of
December 31, 2018,
the Company has unused availability of
$2.0
million on its current line of credit and unused availability of
$0.6
million under its Overdraft Facility. However, our new credit facility will replace these facilities. Including our cash balance, we further have
$16.9
million of positive working capital primarily related to trade accounts receivable and our inventory less current liabilities that we will manage in the next
twelve
 months to create positive cash flow. Considering the above factors and the new line of credit, management believes it is probable that management’s plans will be achieved and will enable the Company to meet its obligations for the
twelve
-month period from the date the financial statements are available to be issued.
 
Principles of Consolidation
The accompanying consolidated financial statements include the accounts of CUI Global, Inc. and its wholly owned subsidiaries CUI Inc., CUI Japan, CUI-Canada, CUI Properties, LLC, Orbital Gas Systems, Ltd. and Orbital Gas Systems, North America, Inc. hereafter referred to as the ‘‘Company.’’ Significant intercompany accounts and transactions have been eliminated in consolidation.
 
Fair Value of Financial Instruments
Accounting Standards Codification (‘‘ASC’’)
820
‘‘Fair Value Measurements and Disclosures’’ (‘‘ASC
820’’
) defines fair value, establishes a framework for measuring fair value under generally accepted accounting principles in the U.S., and enhances disclosures about fair value measurements. ASC
820
describes a fair value hierarchy based on
three
levels of inputs, of which the
first
two
are considered observable and the last unobservable, that
may
be used to measure fair value, which are the following:
 
 
Level
1
– Pricing inputs are quoted prices available in active markets for identical assets or liabilities as of the reporting date.
 
Level
2
– Pricing inputs are quoted for similar assets, or inputs that are observable, either directly or indirectly, for substantially the full term through corroboration with observable market data. Level
2
includes assets or liabilities valued at quoted prices adjusted for legal or contractual restrictions specific to these investments.
 
Level
3
– Pricing inputs are unobservable for the assets or liabilities; that is, the inputs reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability.
 
The Company determines when a financial instrument transfers between levels based on management’s judgment of the significance of unobservable inputs used to calculate the fair value of the financial instrument.
 
Management believes the carrying amounts of the short-term financial instruments, including cash and cash equivalents, investment, note receivable, accounts receivable, contract assets, prepaid expense and other assets, accounts payable, accrued liabilities, contract liabilities, refund liabilities, and other liabilities reflected in the accompanying consolidated balance sheet approximate fair value at
December 
31,
2018
and
2017
due to the relatively short-term nature of these instruments. Mortgage debt and related notes payable approximate fair value based on current market conditions. The Company measures its derivative liability on a recurring basis using significant observable inputs (Level
2
). The Company’s derivative liability is valued using a LIBOR swap curve. As of
December 31, 2018,
the mortgage debt and derivative liability were repaid and had
zero
balances.
 
Cash and Cash Equivalents
Cash includes deposits at financial institutions with maturities of
three
months or less. The Company at times has cash in banks in excess of FDIC insurance limits and places its temporary cash investments with high credit quality financial institutions. The Company considers all highly liquid marketable securities with maturities of
90
days or less at the date of acquisition to be cash equivalents. Cash equivalents include money market funds, certificates of deposit and commercial paper. At
December 
31,
2018
and
2017,
the Company had 
$0.3
million and
$0.9
million, respectively, of cash and cash equivalents balances at domestic financial institutions that were covered under the FDIC insured deposits programs and 
$68
thousand and
$0.2
million, respectively, at foreign financial institutions covered under the United Kingdom Financial Services Compensation (FSC) and the Canada Deposit Insurance Corporation (CDIC). At
December 
31,
2018
and
2017,
the Company held
$0.3
million and
$0.1
million, respectively, in Japanese foreign bank accounts and
$1
thousand and
$0.1
million, respectively, in European foreign bank accounts and
$67
thousand and
$0.1
million, respectively, in Canadian bank accounts. In addition to the Company's unrestricted cash and cash equivalents, the Company has
$523
thousand of long-term restricted cash on its balance sheet related to a contract guarantee. The restricted cash is classified as long term in nature because the contract guarantee extends to the end of
2021.
Restricted cash is combined with other cash and cash equivalents in reconciling the change in cash on the Company's Consolidated Statements of Cash Flows.
 
Investments and Notes Receivable
Test Products International, Inc. ("TPI") is a provider of handheld test and measurement equipment. Through the acquisition of CUI Inc., the Company obtained
352,589
common shares (representing an
8.94%
interest from
January 1
to
March 31, 2014
and
8.5%
thereafter). Through
September 30, 2015,
CUI Global enjoyed a close association with TPI through common related parties, IED, Inc. and James McKenzie as well as through participation that allowed for a significant amount of influence over TPI’s business decisions. Accordingly, through
September 30, 2015,
for financial statement purposes, the Company recognized its investment in TPI under the equity method. Following a determination of reduction in influence and control, the investment was recorded using the cost method.
 
During the
first
quarter of
2016,
the investment in TPI was exchanged for a note receivable from TPI of
$0.4
million, which was the carrying value of the investment, earning interest at
5%
per annum, due
June 30, 2019.
The Company recorded interest income on the note of
$17
thousand,
$18
thousand and
$19
thousand for the years ended
December 31, 2018,
2017
and
2016,
respectively. The interest receivable has been settled on a quarterly basis via a non-cash offset against the finders-fee royalties earned by TPI on GasPT sales. Finders-fee royalties of
$10
thousand,
$16
thousand and
$37
thousand were earned by TPI in the years ended
December 
31,
2018,
2017
and
2016,
respectively, and offset against the note receivable on a quarterly basis. Also, in
2018
and
2017,
the Company received
$19
thousand and
$39
thousand, respectively, in cash payments against the note.  The balance on the note receivable at
December 31, 2018
and
2017
was
$318
thousand and
$330
thousand, respectively. CUI Global reviewed the note receivable for non-collectability as of
December 
31,
2018
and concluded that
no
allowance was necessary.
 
During
2018,
the Company made
two
strategic investments in convertible notes receivable with Virtual Power Systems ("VPS") for a total of
$655
thousand. CUI Inc. is the exclusive
third
-party design and development provider of VPS's ICE (Intelligent Control of Energy) products. See Note
3,
Investments and Fair Value Measurements for more information on these convertible notes.
 
Accounts Receivable and Allowance for Uncollectible Accounts
Accounts receivable consist of the receivables associated with revenue derived from product sales including present amounts due to contracts accounted for under cost-to-cost method. An allowance for uncollectible accounts is recorded to allow for any amounts that
may
not
be recoverable, based on an analysis of prior collection experience, customer credit worthiness and current economic trends. Based on management’s review of accounts receivable, an allowance for doubtful accounts of
$0.2
million and
$0.1
million at
December 
31,
2018
and
2017,
respectively, is considered adequate. The reserve in both periods considers aged receivables that management believes should be specifically reserved for as well as historic experience with bad debts to determine the total reserve appropriate for each period. Receivables are determined to be past due based on the payment terms of original invoices. The Company grants credit to its customers, with standard terms of Net
30
days. The Company routinely assesses the financial strength of its customers and, therefore, believes that its accounts receivable credit risk exposure is limited. Additionally, the Company maintains a foreign credit receivables insurance policy that covers many of the CUI Inc. foreign customer receivable balances in an effort to further reduce credit risk exposure.
 
Activity in the allowance for doubtful accounts for the years ended
December

Inventories
Inventories consist of finished and unfinished products and are stated at the lower of cost or market through either the
first
-in,
first
-out (FIFO) method as a cost flow convention or through the moving average cost method.
 
At
December 
31,
2018,
and
2017,
inventory is presented on the balance sheet net of reserves. The Company provides reserves for inventories estimated to be excess, obsolete or unmarketable. The Company’s estimation process for assessing the net realizable value is based upon its known backlog, projected future demand, historical usage and expected market conditions. Manufactured inventory includes material, labor and overhead. Inventory by category consists of:

In the
fourth
quarter of
2018,
the Company recorded an additional inventory reserve of
$1.4
million related to slow-moving inventory in the Energy segment.
 
Land, Buildings, Improvements, Furniture, Vehicles, Equipment, and Leasehold Improvements
Land is recorded at cost and includes expenditures made to ready it for use. Land is considered to have an infinite useful life.
 
Buildings and improvements are recorded at cost.
 
Furniture, vehicles, and equipment are recorded at cost and include major expenditures, which increase productivity or substantially increase useful lives.
 
Leasehold improvements are recorded at cost and are depreciated over the lesser of the lease term, estimated useful life, or
ten
years.
 
The cost of buildings, improvements, furniture, vehicles, and equipment is depreciated over the estimated useful lives of the related assets.
 
Depreciation is computed using the straight-line method for financial reporting purposes. The estimated useful lives for buildings, improvements, furniture, vehicles, and equipment are as follows:
 
   
Estimated
Useful
Life (years)
 
Buildings and improvements
   
5
to
39
 
Furniture and equipment
   
3
to
10
 
Vehicles
   
3
to
5
 
 
Maintenance, repairs and minor replacements are charged to expenses when incurred. When buildings, improvements, furniture, equipment and vehicles are sold or otherwise disposed of, the asset and related accumulated depreciation are removed from this account, and any gain or loss is included in the statement of operations or as a deferred gain liability on the balance sheets.
 
Long-Lived Assets
Long-lived assets including finite-lived intangible assets are periodically reviewed for impairment whenever circumstances and situations change such that there is an indication that the carrying amounts
may
not
be recoverable. In performing the review for recoverability, the future cash flows expected to result from the use of the asset and its eventual disposition are estimated. If the sum of the expected future cash flows (undiscounted and without interest charges) is less than the carrying amount of the long-lived asset, an impairment loss is recognized as the excess of the carrying amount over the fair value. Otherwise, an impairment loss is
not
recognized. Management estimates the fair value and the estimated future cash flows expected. Any changes in these estimates could impact whether there was impairment and the amount of the impairment.
 
In the
fourth
quarter of
2018,
the Company determined that certain long-term prepaid assets classified on the balance sheet as deposits and other assets, which were reliant on future revenue within the Energy segment in order to be amortized to expense, did
not
have adequate forecasted revenue to justify the current valuation. This was primarily driven by the lack of substantial sales over the last
two
years within the Energy segment and uncertainty regarding the level of future sales. For that reason, the Company recorded a
$1.5
million impairment to deposits and other assets and reclassified
$0.1
million to prepaid assets. The amount reclassified to prepaid assets related to prepaid royalties associated with expected
2019
revenue.
 
In
2018,
the Company also performed an undiscounted cash flows impairment analysis as prescribed under ASC
360
Property, Plant and Equipment
on its long-lived fixed assets and its finite lived intangible assets at Orbital-UK due to an indication that the overall carrying value of the operating unit was
not
recoverable. Based upon that analysis,
no
impairment was identified for those assets.
No
impairments were recognized in
2017
or
2016.
 
Identifiable Intangible Assets
Intangible assets are stated at cost net of accumulated amortization and impairment. The fair value for intangible assets acquired through acquisitions is measured at the time of acquisition utilizing the following inputs, as needed:
 
1.
Inputs used to measure fair value are unadjusted quote prices available in active markets for the identical assets or liabilities if available.
 
2.
Inputs used to measure fair value, other than quoted prices included in
1,
are either directly or indirectly observable as of the reporting date through correlation with market data, including quoted prices for similar assets and liabilities in active markets and quoted prices in inactive markets. This includes assets and liabilities valued using models or other pricing methodologies that do
not
require significant judgment since the input assumptions used in the models, such as interest rates and volatility factors, are corroborated by readily observable data from actively quoted markets for substantially the full life of the asset.
 
3.
Inputs used to measure fair value are unobservable inputs supported by little or
no
market activity and reflect the use of significant management judgment. These values are generally determined using pricing models for which the assumptions utilize management’s estimates of market participant assumptions.
   
4.
Expert appraisal and fair value measurement as completed by
third
-party experts.

Indefinite-lived intangible assets are reviewed annually for impairment and when circumstances suggest.
 
Indefinite-Lived Intangibles and Goodwill Assets
The Company accounts for business combinations under the acquisition method of accounting in accordance with ASC
805,
‘‘Business Combinations,’’ where the total purchase price is allocated to the tangible and identified intangible assets acquired and liabilities assumed based on their estimated fair values. The purchase price is allocated using the information currently available, and
may
be adjusted, up to
one
year from acquisition date, after obtaining more information regarding, among other things, asset valuations, liabilities assumed and revisions to preliminary estimates. The purchase price in excess of the fair value of the tangible and identified intangible assets acquired less liabilities assumed is recognized as goodwill.
 
Annual Test.
The Company tests for impairment of indefinite-lived intangibles and Goodwill in the
second
quarter of each year and whenever events or circumstances indicate that the carrying amount of Goodwill exceeds its fair value and
may
not
be recoverable. The Company’s qualitative assessment for indefinite-lived assets at
May 31, 2018,
followed the guidance in ASC
350
-
30
-
35
-
18A
and
18B.
 
Under current accounting guidance, CUI Global is
not
required to calculate the fair value of a reporting unit unless the entity determines, based on a qualitative assessment, that it is more likely than
not
that its fair value is less than its carrying amount. The guidance includes a number of factors to consider in conducting the qualitative assessment. The Company tests for goodwill impairment in the
second
quarter of each year and whenever events or changes in circumstances indicate that the carrying amount of the asset exceeds its fair value and
may
not
be recoverable.
 
As detailed in ASC
350
-
20
-
35
-
3A,
in performing its testing for Goodwill as of
May 31, 2018,
management completed 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 the qualitative 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.
 
During our review of Goodwill as of
May 31, 2018,
the Company determined that there were indicators present to suggest that it was more likely than
not
that the fair value of the Orbital-UK reporting unit was less than its carrying amount.
 
The significant changes for the Orbital-UK reporting unit subsequent to the most recent impairment test performed as of
December 31, 2017
included a decline in the
2018
actual revenue, operating income and cash flows compared to prior forecasts for the same period and a negative change in the
2018
forecasted revenue, operating income and cash flows for the remainder of the year due in part to the longer than expected temporary halt in shipping of its GasPT product to a major customer in Italy and market uncertainty due to the continuing effects of Brexit.
 
To test the Orbital-UK reporting unit for impairment as of
May 31, 2018,
the Company used a quantitative test. The Company estimated the fair value of the Orbital-UK reporting unit using a blend of a market approach and an income approach, which was deemed to be the most indicative of fair value in an orderly transaction between market participants. Under the income approach, the Company determined fair value based on estimated future cash flows of the Orbital-UK reporting unit discounted by an estimated weighted-average cost of capital, reflecting the overall level of inherent risk of the Orbital-UK reporting unit and the rate of return an outside investor would expect to earn. The Company based its cash flow projections for the Orbital-UK reporting unit using a forecast of cash flows and a terminal value developed by capitalizing an assumed stabilized cash flow figure. The forecast and related assumptions were derived from an updated financial forecast prepared during the
second
quarter of
2018.
At that time, a key assumption related to the recoverability of the Orbital-UK reporting unit Goodwill was the resumption of delivery of GasPT product to
one
of our major customers and continued strengthening of our integration revenues. Under the market approach, appropriate valuation multiples were derived from the historical operating data of selected guideline companies. The valuation multiples were evaluated and adjusted based on the strengths and weaknesses of the Company relative to the selected guideline companies and the multiple was then applied to the appropriate operating data of the Company to arrive at an indication of fair market value. As a result of the analysis, the Company concluded that the carrying value of the Orbital-UK reporting unit exceeded its estimated fair value. The quantitative test for the Orbital-UK reporting unit resulted in an impairment for the Orbital-UK reporting unit, and the Company recorded a Goodwill impairment charge of
$1.3
million during the
second
quarter of
2018.
 
December 2018
Interim Test.
During the
fourth
quarter of
2018,
the Company determined there were indicators present to suggest that it was more likely than
not
that the fair value of the Orbital-UK reporting unit was less than its carrying amount. The significant changes for the Orbital-UK reporting unit subsequent to the annual goodwill impairment test performed as of
May 31, 2018
were driven by a slower recovery in the Energy segment than originally forecasted. Actual GasPT revenue continued to lag behind forecasted revenue as acceptance of the technology continued to be slower than anticipated and delays associated with existing customer contracts that have
not
yet resumed. This slower than expected recovery, led to lower
2018
Energy segment revenue, operating income and cash flows than originally forecasted.
 
To test the Orbital-UK reporting unit for impairment, the Company used a quantitative test similar to the
one
used at
May 31, 2018
with updated financial forecasts and assumptions based on the information available at
December 31, 2018.
As a result of the analysis, the Company concluded that the carrying value of the Orbital-UK reporting unit exceeded its estimated fair value. The quantitative test for the Orbital-UK reporting unit resulted in an impairment for the Orbital-UK reporting unit, and the Company recorded a goodwill impairment charge of
$3.1
million during the
fourth
quarter of
2018,
which was a write-off of the remaining Energy segment goodwill. In addition, the reporting units in the Power and Electromechanical segment were also tested for impairment due to the overall decrease in market capitalization experienced in
2018.
 
 
As of
December 31, 2018,
there was goodwill remaining for CUI Inc., CUI-Canada and CUI-Japan reporting units, which are included in the Power and Electromechanical segment.
 
December 2017
Interim Test.
During the
fourth
quarter of
2017,
the Company determined that there were indicators present to suggest that it was more likely than
not
that the fair value of the Orbital-UK reporting unit was less than its carrying amount. The significant changes for the Orbital-UK reporting unit subsequent to the annual goodwill impairment test performed as of
May 31, 2017
included a decline in the
2017
actual revenue, operating income and cash flows compared to previously forecasted results and a decline in the
2018
forecasted revenue, operating income and cash flows due in part to the longer than expected temporary halt in shipping of its GasPT product to a major customer in Italy and market uncertainty due to the continuing effects of Brexit.
 
To test the Orbital-UK reporting unit for impairment, the Company used a quantitative test. The Company estimated the fair value of the Orbital-UK reporting unit using a blend of a market approach and an income approach, which was deemed to be the most indicative of fair value in an orderly transaction between market participants. Under the income approach, the Company determined fair value based on estimated future cash flows of the Orbital-UK reporting unit discounted by an estimated weighted-average cost of capital, reflecting the overall level of inherent risk of the Orbital-UK reporting unit and the rate of return an outside investor would expect to earn. The Company based its cash flow projections for the Orbital-UK reporting unit using a forecast of cash flows and a terminal value developed by capitalizing an assumed stabilized cash flow figure. The forecast and related assumptions were derived from an updated financial forecast prepared during the
fourth
quarter of
2017.
Under the market approach, appropriate valuation multiples were derived from the historical operating data of selected guideline companies. The valuation multiples were evaluated and adjusted based on the strengths and weaknesses of the Company relative to the selected guideline companies and the multiple was then applied to the appropriate operating data of the Company to arrive at an indication of fair market value. As a result of the analysis, the Company concluded that the carrying value of the Orbital-UK reporting unit exceeded its estimated fair value. The quantitative test for the Orbital-UK reporting unit resulted in an impairment for the Orbital-UK reporting unit, and the Company recorded a goodwill impairment charge of
$3.2
million during the
fourth
quarter of
2017.
 
2016
Annual Test.
In
2016,
the analysis, determined there was
no
impairment necessary to goodwill. Through these reviews, management concluded 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
350
-
20
-
35
-
3C
in accordance with current accounting guidance. On a periodic basis, we will also perform a quantitative analysis of goodwill impairment and in
2016,
in addition to the qualitative analysis, we performed a quantitative analysis of goodwill impairment and concluded
no
impairment of goodwill was required.
 
Patent Costs
The Company estimates the patents it has filed have a future beneficial value; therefore it capitalizes the costs associated with filing for its patents. At the time the patent is approved, the patent costs associated with the patent are amortized over the useful life of the patent. If the patent is
not
approved, at that time the costs will be expensed.
 
Accrued expenses
Accrued expenses are liabilities that reflect expenses on the statement of operations that have
not
been paid or recorded in accounts payable at the end of the period. At
December 
31,
2018
and
December 
31,
2017,
accrued expenses of
$4.9
million and
$4.2
million, respectively, included
$1.7
million and
$1.9
million, respectively, of accrued compensation and
$1.7

Derivative instruments
The Company uses various derivative instruments including forward currency contracts, and interest rate swaps to manage certain exposures. These instruments are entered into under the Company’s corporate risk management policy to minimize exposure and are
not
for speculative trading purposes. The Company recognizes all derivatives as either assets or liabilities in the consolidated balance sheet and measures those instruments at fair value. Changes in the fair value of derivatives are recognized in earnings. The Company has limited involvement with derivative instruments and does
not
trade them. From time to time, the Company
may
enter into foreign currency exchange contracts to minimize the risk associated with foreign currency exchange rate exposure from expected future cash flows. The Company had entered into
one
interest rate swap, which had a maturity date of
ten
years from the date of inception, and was used to minimize the interest rate risk on the variable rate mortgage. During the years ended
December 
31,
2018,
2017
and
2016,
the Company had a non-cash gain and unrealized gains of
$129
thousand,
$111
thousand, and
$113
thousand, respectively, related to the derivative liabilities. During the year ended
December 31, 2018,
the Company paid
$227
thousand to close out the interest rate swap in conjunction with the repayment of the related variable rate mortgage.
 
Derivative Liabilities
The Company evaluates embedded conversion features pursuant to FASB Accounting Standards Codification
No.
815
(‘‘FASB ASC
815’’
), ‘‘Derivatives and Hedging,’’ which requires a periodic valuation of the fair value of derivative instruments and a corresponding recognition of liabilities associated with such derivatives.
 
Stock-Based Compensation
The Company records its stock-based compensation expense under its stock option plans and also issues stock for services. The Company accounts for stock-based compensation using FASB Accounting Standards Codification
No.
718
(‘‘FASB ASC
718’’
), ‘‘Compensation – Stock Compensation.’’ FASB ASC
718
requires the fair value of all stock-based employee compensation awarded to employees to be recorded as an expense over the related vesting period.
 
Stock bonuses issued to employees are recorded at fair value using the market price of the stock on the date of grant and expensed over the vesting period or immediately if fully vested on date of issuance. Employee stock options are recorded at fair value using the Black-Scholes option pricing model. The underlying assumptions used in the Black-Scholes option pricing model by the Company are taken from publicly available sources including: (
1
) volatility, which is calculated using historic stock price information from online finance websites such as Google Finance and Yahoo Finance; (
2
) the stock price on the date of grant is obtained from online finance websites such as those previously noted; (
3
) the appropriate discount rates are obtained from the United States Federal Reserve economic research and data website; and (
4
) other inputs are determined based on previous experience and related estimates. With regards to expected volatility, the Company utilizes an appropriate period for historical share prices for CUI Global that best reflect the expected volatility for determining the fair value of its stock options.
 
See Note 
10
Stockholders' Equity for additional disclosure and discussion of the employee stock plan and activity.
 
Common stock, stock options and common stock warrants issued to other than employees or directors are also recorded on the basis of their fair value, as required by FASB ASC
505,
which is measured as of the date required by FASB ASC
505,
‘‘Equity – Based Payments to Non-Employees.’’ In accordance with FASB ASC
505,
the stock options or common stock warrants are valued using the Black-Scholes option pricing model on the basis of the market price of the underlying common stock on the ‘‘valuation date,’’ which for options and warrants related to contracts that have substantial disincentives to non-performance is the date of the contract, and for all other contracts is the performance completion date. Expense related to the options and warrants is recognized on a straight-line basis over the shorter of the period over which services are to be received or the vesting period. Where expense must be recognized prior to a valuation date, the expense is computed based off an estimate of the fair value of the stock award as valued under the Black-Scholes option pricing model on the basis of the market price of the underlying common stock at the end of the period, and any subsequent changes in the market price of the underlying common stock up through the valuation date is reflected in the expense recorded in the subsequent period in which that change occurs.
 
Common stock issued to other than employees or directors subject to performance (performance based awards) require interpretation to include ASC
505
-
50
-

as to when the counterparty’s performance is complete based on delivery, or other relevant performance criteria in accordance with the relevant agreement. When performance is complete, the common stock is issued and the expense recorded on the basis of their value as required by FASB ASC
505
on the date the performance requirement is achieved.
 
Defined Contribution Plans
The Company has a
401
(k) retirement savings plan that allows employees to contribute to the plan after they have completed
60
days of service and are
18
years of age. The Company matches the employee's contribution up to
6%
of total compensation. CUI Inc., Orbital Gas Systems, North America, Inc., and CUI Global made total employer contributions, net of forfeitures, of
$0.5
million,
$0.4
million, and
$0.4
million for
2018,
2017
and
2016,
respectively.
 
Orbital-UK operates a defined contribution retirement benefit plan for employees who have been employed with the company at least
12
months and who chose to enroll in the plan. Orbital-UK contributes to its plan the equivalent of
5%
of the employee's salary and the employee has the option to contribute pre-tax earnings. Orbital-UK made total employer contributions of
$0.3
million,
$0.2
million and
$0.3
million during
2018,
2017,
and
2016,
respectively.
 
Revenue Recognition
On
January 1, 2018,
we adopted the new accounting standard ASC
606,
“Revenue from Contracts with Customers” and all the related amendments (“new revenue standard"), which supersedes nearly all existing revenue recognition guidance under U.S. GAAP. This guidance includes the required steps to achieve the core principle that a company should recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The new revenue standard was applied using the modified retrospective method. We recognized the cumulative effect of initially applying the new revenue standard as an adjustment to accumulated deficit as of
January 1, 2018.
As a result of the adoption of this standard, certain changes have been made to the consolidated balance sheets. We expect the ongoing impact of the adoption of the new standard to primarily affect the timing of revenue recognition. The most significant impact was on Power and Electromechanical segment revenue with certain distribution customers that was previously recorded as “sell through." Under the new accounting guidance, we record the revenue upon sale to the distributor with an appropriate amount reserved for estimated returns and allowances as the Company recognizes revenue at the time the related performance obligation is satisfied by transferring a promised good or service to its customers. For the Power and Electromechanical segment, their revenue is based upon the transfer of goods and satisfaction of its performance obligations as of a point in time. During the transition this had the effect of having a certain amount of revenue
not
recorded as revenue but as part of the cumulative effect of the accounting change. For the majority of contracts in the Energy segment, revenue is still measured over time using the cost-to-cost method. The change that most affected the transition adjustment on Energy segment revenue was the requirement to limit revenue recognition on contracts without an enforceable right to payment for performance completed to date. Revenue on contracts without a specific enforceable right to payment on work performed to date was "clawed back" as part of the Company's transition adjustment. The cumulative effect adjustment recorded as of
January 1, 2018
was a net
$1.9
million decrease to accumulated deficit due to a
$2.8
million transition adjustment from the Power and Electromechanical segment partially offset by a $(
0.9
) million transition adjustment from the Energy segment, net of deferred tax.

had

impact on the Company’s cash flows from operations.
 
Power and Electromechanical segment
The Power and Electromechanical segment generates its revenue from
two
categories of products:
power supply solutions
 - including external and embedded ac-dc power supplies, dc-dc converters, basic digital point of load modules, ICE (Intelligent Control of Energy) products enabled by the VPS patented software system and offering a technology architecture that addresses power and related accessories; and 
components
 - including connectors, speakers, buzzers, and industrial control solutions including encoders and sensors. These offerings provide a technology architecture that addresses power and related accessories to industries as broadly ranging as telecommunications, consumer electronics, medical and defense, among others. The production and delivery of these products are considered single performance obligations. Revenue is recognized when we satisfy a performance obligation and this occurs upon shipment and ownership transfer of our products to our customers at a point in time.
 
Energy segment
The Energy segment subsidiaries, collectively referred to as Orbital Gas Systems (Orbital), generate their revenue from a portfolio of products, services and resources that offer a diverse range of personalized gas engineering solutions to the gas utilities, power generation, petrochemical, emissions, manufacturing and automotive industries, among others.
 
Orbital accounts for a majority of its contract revenue proportionately over time. For our performance obligations satisfied over time, we recognize revenue by measuring the progress toward complete satisfaction of that performance obligation. The selection of the method to measure progress towards completion can be either an input method or an output method and requires judgment based on the nature of the goods or services to be provided.
 
For our construction contracts, revenue is generally recognized over time as our performance creates or enhances an asset that the customer controls. Our fixed price construction projects generally use a cost-to-cost input method to measure our progress towards complete satisfaction of the performance obligation as we believe it best depicts the transfer of control to the customer. Under the cost-to-cost measure of progress, the extent of progress towards completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation.
 
The timing of revenue recognition for Energy products also depends on the payment terms of the contract, as our performance does
not
create an asset with an alternative use to us. For those contracts which we have a right to payment for performance completed to date at all times throughout our performance, inclusive of a cancellation, we recognize revenue over time. As discussed above, these performance obligations use a cost-to-cost input method to measure our progress towards complete satisfaction of the performance obligation as we believe it best depicts the transfer of control to the customer. However, for those contracts for which we do
not
have a right, at all times, to payment for performance completed to date, we recognize revenue at the point in time when control is transferred to the customer.
 
For our service contracts, revenue is also generally recognized over time as the customer simultaneously receives and consumes the benefits of our performance as we perform the service. For our fixed price service contracts with specified service periods, revenue is generally recognized on a straight-line basis over such service period when our inputs are expended evenly, and the customer receives and consumes the benefits of our performance throughout the contract term.
 
For certain of our revenue streams, such as call-out repair and service work, and outage services, that are performed under time and materials contracts, our progress towards complete satisfaction of such performance obligations is measured using an output method as the customer receives and consumes the benefits of our performance completed to date.
 
Due to uncertainties inherent in the estimation process, it is possible that estimates of costs to complete a performance obligation will be revised in the near-term. For those performance obligations for which revenue is recognized using a cost-to-cost input method, changes in total estimated costs, and related progress towards complete satisfaction of the performance obligation, are recognized on a cumulative catch-up basis in the period in which the revisions to the estimates are made. When the current estimate of total costs for a performance obligation indicate a loss, a provision for the entire estimated loss on the unsatisfied performance obligation is made in the period in which the loss becomes evident.
 
Product-type contracts (for example, sale of GasPT units) for which revenue does
not
qualify to be recognized over time are recognized at a point in time. Revenues from warranty and maintenance activities are recognized ratably over the term of the warranty and maintenance period.
 
Accounts Receivable, Contract Assets and Contract Liabilities
Accounts receivable are recognized in the period when our right to consideration is unconditional. Accounts receivable are recognized net of an allowance for doubtful accounts. A considerable amount of judgment is required in assessing the likelihood of realization of receivables.
 
The timing of revenue recognition
may
differ from the timing of invoicing to customers. Contract assets include unbilled amounts from our construction projects when revenue recognized under the cost-to-cost measure of progress exceed the amounts invoiced to our customers, as the amounts cannot be billed under the terms of our contracts. Such amounts are recoverable from our customers based upon various measures of performance, including achievement of certain milestones, completion of specified units or completion of a contract. Also included in contract assets are amounts we seek or will seek to collect from customers or others for errors or changes in contract specifications or design, contract change orders or modifications in dispute or unapproved as to both scope and/or price or other customer-related causes of unanticipated additional contract costs (claims and unapproved change orders). Our contract assets do
not
include capitalized costs to obtain and fulfill a contract. Contract assets are generally classified as current within the Consolidated Balance Sheets.
 
Contract liabilities from our construction contracts occur when amounts invoiced to our customers exceed revenues recognized under the cost-to-cost measure of progress. Contract liabilities additionally include advanced payments from our customers on certain contracts. Contract liabilities decrease as we recognize revenue from the satisfaction of the related performance obligation and are recorded as either current or long-term, depending upon when we expect to recognize such revenue.

Refund Liabilities and Corresponding Inventory Adjustment
Refund liabilities primarily represent estimated future new product introduction returns and estimated future scrap returns. Estimated future returns and allowances are reserved based on historical return rates. In addition to the refund liabilities recorded for future returns, the Company also records an adjustment to inventory and corresponding adjustment to cost of revenue for the Company's right to recover products from customers upon settling the refund liability.
 
Performance Obligations
Remaining Performance Obligations
Remaining performance obligations, represents the transaction price of firm orders for which work has
not
been performed and excludes unexercised contract options and potential orders under ordering-type contracts. As of 
December 31, 2018, 
the Company's remaining performance obligations are generally expected to be filled within the next
12
months.
 
Any adjustments to net revenues, cost of revenues, and the related impact to operating income are recognized as necessary in the period they become known. These adjustments
may
result from positive program performance, and
may
result in an increase in operating income during the performance of individual performance obligations, if we determine we will be successful in mitigating risks surrounding the technical, schedule and cost aspects of those performance obligations. Likewise, these adjustments
may
result in a decrease in operating income if we determine we will
not
be successful in mitigating these risks. Changes in estimates of net revenues, cost of revenues and the related impact to operating income are recognized on a cumulative catch-up basis in the period they become known, which recognizes in the current period the cumulative effect of the changes on current and prior periods based on a performance obligation's percentage of completion. A significant change in
one
or more of these estimates could affect the profitability of
one
or more of our performance obligations. For separately priced extended warranty or product maintenance performance obligations, when estimates of total costs to be incurred on the performance obligation exceed total estimates of revenue to be earned, a provision for the entire loss on the performance obligation is recognized in the period the loss is determined.
 
Performance Obligations Satisfied Over Time
To determine the proper revenue recognition method for contracts for our Energy segment, we evaluate whether a single contract should be accounted for as more than
one
performance obligation. This evaluation requires significant judgment and the decision to separate the single contract into multiple performance obligations could change the amount of revenue and profit recorded in a given period.
 
For most of our contracts, the customer contracts with us to provide a significant service of integrating a complex set of tasks and components into a single project or capability (even if that single project results in the delivery of multiple units). Hence, the entire contract is accounted for as
one
performance obligation. Less commonly, however, we
may
promise to provide distinct goods or services within a contract in which case we separate the contract into more than
one
performance obligation. If a contract is separated into more than
one
performance obligation, we allocate the total transaction price to each performance obligation in an amount based on the estimated relative standalone selling prices of the promised goods or services underlying each performance obligation. We infrequently sell standard products with observable standalone sales. In cases where we do, the observable standalone sales are used to determine the standalone selling price. More frequently, we sell a customized customer specific solution, and in these cases we typically use the expected cost plus a margin approach to estimate the standalone selling price of each performance obligation.
 
Performance Obligations Satisfied at a Point in Time.
Revenue from goods and services transferred to customers at a single point in time accounted for 
84%
of revenues for the year ended
December 31, 2018.
The majority of our revenue recognized at a point in time is in our Power and Electromechanical segment. Revenue on these contracts is recognized when the product is shipped and the customer takes ownership of the product. Determination of ownership and control transfer is determined by shipping terms delineated on the customer purchase orders.
 
Variable Consideration
The nature of our contracts gives rise to several types of variable consideration, including new product introduction returns and scrap return allowances primarily in our Power and Electromechanical segment. In rare instances in our Energy segment, we include in our contract estimates, additional revenue for submitted contract modifications or claims against the customer when we believe we have an enforceable right to the modification or claim, the amount can be estimated reliably and its realization is probable. In evaluating these criteria, we consider the contractual/legal basis for the claim, the cause of any additional costs incurred, the reasonableness of those costs and the objective evidence available to support the claim. We include new product introduction and scrap return estimates in our calculation of net revenue when there is a basis to reasonably estimate the amount of the returns. These estimates are based on historical return experience, anticipated returns and our best judgment at the time. These amounts are included in our calculation of net revenue recorded for our contracts and the associated remaining performance obligations.

2016
 
As discussed above, ASC
606
was adopted on a modified retrospective basis and accordingly the
2017
and
2016
financial statements were
not
restated for ASC
606.
For
2017
and
2016,
revenue was recognized as follows.
 
Power and Electromechanical segment
Product revenue was recognized in the period when persuasive evidence of an arrangement with a customer existed, the products were shipped and title had transferred to the customer, the price was fixed or determinable, and collection was reasonably assured. The Company sells to distributors pursuant to distribution agreements that have certain terms and conditions such as the right of return and price protection, which inhibited revenue recognition unless they could be reasonably estimated as we could
not
assert the price was fixed and determinable and estimate returns. For
one
distributor that comprises
26%
of consolidated revenue in
2017,
we had such history and ability to estimate and therefore recognized revenue upon sale to the distributor and recorded a corresponding reserve for the estimated returns. For
three
other distributor arrangements that represented a combined
15%
of revenue in
2017,
we recognized revenue on a sell-through basis, and accordingly deferred revenue and the related costs until such time as the distributor resold the product.
 
Energy segment
For production-type contracts meeting the Company’s minimum threshold, revenues and related costs on these contracts were recognized using the ‘‘percentage of completion method’’ of accounting in accordance with ASC
605
-
35,
 
Accounting for Performance of Construction-Type and Certain Production Type Contracts 
(‘‘ASC
605
-
35’’
). Under this method, contract revenues and related expenses were recognized over the performance period of the contract in direct proportion to the costs incurred as a percentage of total estimated costs for the entirety of the contract. Costs included direct material, direct labor, subcontract labor and any allocable indirect costs. The Company captured certain job costs as work progressed, including labor, material and costs
not
invoiced. Margin adjustments were made as information pertaining to contracts changed. All un-allocable indirect costs and corporate general and administrative costs were charged to the periods as incurred. The amount of costs
not
invoiced were captured to ensure an estimated margin consistent with that expected at the completion of the project. In the event a loss on a contract was foreseen, the Company recognized the loss when it was determined. Contract costs plus recognized profits were accumulated as deferred assets, and billings and/or cash received were recorded to a deferred revenue liability account. The net of these
two
accounts for any individual project was presented as ‘‘Costs in excess of billings,’’ an asset account, or ‘‘Billings in excess of costs,’’ a liability account.
 
Production-type contracts that did
not
qualify for use of the percentage of completion method were accounted for using the ‘‘completed contract method’’ of accounting in accordance with ASC
605
-
35
-
25
-
57.
Under this method, contract costs were accumulated as deferred assets, and billings and/or cash received was recorded to a deferred revenue liability account, during the periods of construction, but
no
revenues, costs, or profits were recognized in operations until the period within which completion of the contract occurred. A contract was considered complete when all costs except insignificant items were incurred; the equipment was operating according to specifications and was accepted by the customer.
 
For product sales in the Energy segment, revenue was recognized in the period when persuasive evidence of an arrangement with a customer existed, the products were shipped and title had transferred to the customer, the price was fixed or determinable, and collection was reasonably assured.
 
Revenues from warranty and maintenance activities were recognized ratably over the term of the warranty and maintenance period and the unrecognized portion was recorded as deferred revenue.
 
Shipping and Handling Costs
Amounts billed to customers in sales transactions related to shipping and handling represent revenues earned for the goods provided and are included in sales, and were approximately
$27
thousand,
$17
thousand, and
$23
thousand, for the years ended
December 
31,
2018,
2017
and
2016,
respectively. The Company expenses inbound shipping and handling costs as cost of revenues.
 
Warranty Reserves
A warranty reserve liability is recorded based on estimates of future costs on sales recognized. At
December 
31,
2018
and
2017,
the balance of approximately
$37
thousand and
$40
thousand, respectively, for warranty reserve liability is included in accrued expenses on the balance sheet.
 
Advertising
The costs incurred for producing and communicating advertising are charged to operations as incurred. Advertising expense for the years ended
December 
31,
2018,
2017
 and
2016
were
$2.0
million,
$1.8
million, and
$1.7
million, respectively. In addition to these advertising costs, the Company also incurs advertising related costs for advertising completed in partnership with its distributors. These costs are offset against revenues. During
2018,
2017
and
2016,
the advertising costs offset against revenues were
$0.6
million,
$0.3
million, and
$0.3
million, respectively.
 
Income Taxes
Income taxes are accounted for under the asset and liability method of FASB Accounting Standards Codification
No.
740
(‘‘FASB ASC
740’’
), ‘‘Income Taxes.’’ Under FASB ASC
740,
deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized as income in the period that includes the enactment date. Deferred tax assets are reduced by a valuation allowance to the extent that management believes it is more likely than
not
that such deferred tax assets will
not
be realized.
 
Valuation allowances have been established against all domestic based deferred tax assets and U.K. based deferred tax assets due to uncertainties in the Company’s ability to generate sufficient taxable income in future periods to make realization of such assets more likely than
not.
  In future periods, tax benefits and related domestic and U.K. deferred tax assets will be recognized when management considers realization of such amounts to be more likely than
not.
The Company has
not
provided for valuation allowances on deferred tax assets in any other jurisdiction.
 
The Company recognizes interest and penalties, if any, related to its tax positions in income tax expense.
 
CUI Global files consolidated income tax returns with its U.S. based subsidiaries for federal and many state jurisdictions in addition to separate subsidiary income tax returns in Japan, the United Kingdom and Canada. As of
December 
31,
2018,
the Company is
not
under examination by any income tax jurisdiction. The Company is
no
longer subject to USA examination for years prior to
2015.
 
Net Loss per Share
In accordance with FASB Accounting Standards Codification
No.
260
(‘‘FASB ASC
260’’
), ‘‘Earnings per Share,’’ basic net loss per share is computed by dividing the net 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
2018,
2017
and
2016,
the assumed exercise of stock options using the treasury stock method would have had an antidilutive effect and therefore all options for each of the
three
years were excluded from the calculation of diluted net loss per share. Accordingly, diluted net loss per share is the same as basic net loss per share for
2018,
2017
and
2016.
The weighted average shares outstanding included 
1,844;
63,602
and
25,811
of shares that are considered outstanding, but unissued as of
December 
31,
2018,
2017
and
2016,
respectively, for shares to be issued in accordance with a royalty agreement pertaining to sales of the GasPT devices and unpaid equity share bonuses in
2017
and
2016.
 
The following table summarizes the number of stock options outstanding excluding amounts applicable to contingent conversion option, which
may
dilute future earnings per share:

Foreign Currency Translation
The financial statements of the Company's foreign offices have been translated into U.S. dollars in accordance with FASB ASC
830,
‘‘Foreign Currency Matters’’ (FASB ASC
830
). All balance sheet accounts have been translated using the exchange rate in effect at the balance sheet date.  Statement of Operations amounts have been translated using an appropriately weighted average exchange rate for the year. The translation gains and losses resulting from the changes in exchange rates during
2018,
2017
and
2016
have been reported in accumulated other comprehensive income (loss), except for gains and losses resulting from the translation of intercompany receivables and payables, which are included in earnings for the period.
 
Segment Reporting
Operating segments are defined in accordance with ASC
280
-
10
as components of an enterprise for which separate financial information is available that is evaluated regularly by the chief operating decision maker, or decision-making group, in deciding how to allocate resources and in assessing performance. The measurement basis of segment profit or loss is income (loss) from operations. Management has identified
six
operating segments based on the activities of the Company in accordance with ASC
280
-
10.
These operating segments have been aggregated into
three
reportable segments. The
three
reportable segments are Power and Electromechanical, Energy and Other. The Power and Electromechanical segment is focused on the operations of CUI Inc., CUI-Canada, Inc. and CUI Japan for the sale of internal and external power supplies and related components and industrial controls. The Energy segment is focused on the operations of Orbital Gas Systems Ltd. and Orbital Gas Systems, North America, Inc. which includes gas related test and measurement systems, including the GasPT. The Other segment represents the remaining activities that are
not
included as part of the other reportable segments and represent primarily corporate activity.

is intended to provide financial statement users with more useful information about expected credit losses on financial assets held by a reporting entity at each reporting date. The new standard replaces the existing incurred loss impairment methodology with a methodology that requires consideration of a broader range of reasonable and supportable forward-looking information to estimate all expected credit losses. This ASU is effective for fiscal years and interim periods within those years beginning after

Leases (Topic
842
)
 (‘‘ASU
2016
-
02’’
). ASU
2016
-
02
requires lessees to present right-of-use assets and lease liabilities on the balance sheet. The new guidance will be effective for public business entities for fiscal years beginning after
December 15, 2018
including interim periods within that fiscal year. We will adopt the standard in the
first
quarter of
2019.
As part of the transition, we will utilize the effective date method of implementation. Under the effective date method, we will include the new required disclosures for the current period and provide the disclosures required by the previous guidance found in ASC
840
for the prior year comparative periods. In addition, we will elect to utilize the package of practical expedients permitted under the transition guidance within the new standard, which among other things, will allow us to carry forward the historical lease classifications and allow us to exclude leases with an initial term of
12
months or less from being recorded on the Company's balance sheet; we will recognize lease expense for these short-term leases on a straight-line basis over the lease term.
 
Upon adoption, we expect to record a right-of-use asset and a corresponding lease liability for the Company's operating leases where the Company is the lessee. The potential effect on the Company's consolidated financial statements is largely based on the present value of future minimum lease payments, the amount of which will depend upon the population of leases in effect at the date of adoption. The present value of future minimum lease payments totaled
$7.8
million as of
December 31, 2018.
In addition, we will have a
$2.9
million adjustment to retained earnings at
January 1, 2019
as a result of recognizing the gain on the sale-leaseback transaction. We do
not
expect material changes to the recognition of operating lease expense in the Company's consolidated statements of operation.
