Summary of Significant Accounting Policies [Abstract] |
Principles of Consolidation | Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated on consolidation.
Reclassifications | Reclassifications Certain reclassifications have been made in prior years’ financial statements to conform to the presentation used in the current year. These reclassifications have not resulted in any changes to the previously reported net income for any year.
Use of Estimates | Use of Estimates The preparation of financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The financial statements include estimates based on currently available information and management's judgment as to the outcome of future conditions and circumstances. Significant estimates in these financial statements include allowance for doubtful accounts receivable, inventory provision, useful lives and impairment of long-lived assets, income tax provision, goodwill impairment, cost of pension benefits and estimates related to purchase price allocation. Changes in the status of certain facts or circumstances could result in material changes to the estimates used in the preparation of the financial statements and actual results could differ from the estimates and assumptions.
Revenue Recognition | Revenue Recognition Revenue is recognized when (1) persuasive evidence of an arrangement exists, (2) delivery occurs, (3) the sales price is fixed or determinable, (4) collectability is reasonably assured and (5) customer acceptance criteria, if any, has been successfully demonstrated. Revenue is recognized on the sale of goods, when the significant risks and rewards of ownership have been transferred to the buyer upon delivery, provided that the Company maintains neither managerial involvement to the degree usually associated with ownership, nor effective control over the goods sold. There are no further obligations on the part of the Company subsequent to revenue recognition, except when customers have the right of return or when the Company warrants the product. The Company records a provision for future returns, based on historical experience at the time of shipment of products to customers. The Company warrants some of its products against defects in design, materials and workmanship for periods ranging primarily from one to ten years depending on the model. The Company records a provision for estimated future warranty costs based on the historical relationship of warranty claims to sales at the time of shipment of products to customers. The Company periodically reviews the adequacy of its product warranties and adjusts, if necessary, the warranty percentage and accrued warranty reserve for actual experience. Service revenue primarily consists of preventative maintenance and monitoring services, as well as the provision of after-market support related to equipment sales and project commissioning service revenue. Revenues from these services are recognized when the service is performed and the customer has accepted the work.
Cost of Goods Sold | Cost of Goods Sold Cost of goods sold for the T&D Solutions and Critical Power Solutions segments primarily includes charges for materials, direct labor and related benefits, freight (inbound and outbound), direct supplies and tools, purchasing and receiving costs, inspection costs, internal transfer costs, warehousing costs and utilities related to production facilities and, where appropriate, an allocation of overhead. Cost of goods sold for Critical Power Solutions also includes indirect labor and infrastructure cost related to the provision of field services.
Financial Instruments | Financial Instruments The Company’s financial instruments consist primarily of cash and cash equivalents, receivables, payables and debt instruments. The carrying values of these financial instruments approximate their respective fair values as they are either short-term in nature or carry interest rates which are periodically adjusted to market rates. Unless otherwise indicated, the carrying value of these financial instruments approximates their fair market value.
Cash and Cash Equivalents | Cash and Cash Equivalents Cash and cash equivalents comprise cash on hand, demand deposits and investments with an original maturity at the date of purchase of three months or less.
Accounts Receivable | Accounts Receivable The Company accounts for trade receivables at original invoice amount less an estimate made for doubtful receivables based on a review of all outstanding amounts on a monthly basis. Management determines the allowance for doubtful accounts by regularly evaluating individual customer receivables and considering a customer's financial condition, credit history and current economic conditions. The Company writes off trade receivables when they are deemed uncollectible. The Company records recoveries of trade receivables previously written off when it receives them. Management considers the Company’s allowance for doubtful accounts, which was $0.6 million and $0.6 million as of December 31, 2015 and 2014, respectively, sufficient to cover any exposure to loss in its accounts receivable.
Long-Lived Assets | Long-Lived Assets Depreciation and amortization for property, plant and equipment, and finite life intangible assets, is computed and included in cost of goods sold and in selling and administrative expense, as appropriate. Long-lived assets, consisting primarily of property, plant and equipment, are stated at cost less accumulated depreciation. Property, plant and equipment are depreciated using the straight line method, based on the estimated useful lives of the assets (buildings – 25 years, machinery and equipment - 5 to 15 years, computer hardware and software - 3 to 5 years, furniture & fixtures 5 to 7 years, leasehold improvements – term of lease). Depreciation commences once the assets are ready for their intended use. Finite life intangible assets consist primarily of customer relationships in multiple categories that are specific to the businesses acquired and for which estimated useful lives were determined based on actual historical customer attrition rates. The Company’s other finite life intangible assets consist of non-compete agreements, which have defined terms, certain trademarks which the Company has elected to gradually discontinue, and internally-developed software. These finite life intangible assets are amortized by the Company over periods ranging from one to twenty years. Long-lived assets and finite life intangible assets are reviewed for impairment whenever events or circumstances have occurred that indicate the remaining useful life of the asset may warrant revision or that the remaining balance of the asset may not be recoverable. Upon indications of impairment, or in the normal course of annual testing, assets and liabilities are grouped at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. The measurement of possible impairment is generally estimated by the ability to recover the balance of an asset group from its expected future operating cash flows on an undiscounted basis. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the asset exceeds the fair value thereof. Determining asset groups and underlying cash flows requires the use of significant judgment. In 2015, due to relocation of Bemag, the Company recorded an impairment charge of $261 for customer relationships. No impairment was recorded in 2014.
Goodwill and Indefinite Life Intangible Assets | Goodwill and Indefinite Life Intangible Assets Goodwill was generated through the acquisitions made by the Company between 2010 and 2015. As the total consideration paid exceeded the value of the net assets acquired, the Company recorded goodwill for each of the completed acquisitions. At the date of acquisition, the Company performed a valuation to determine the value of the intangible assets, and the allocation of the purchase price to the assets and liabilities acquired. The goodwill is attributable to synergies and economies of scale provided to us by the acquired entity. The Company tests its goodwill and indefinite-lived intangible asset for impairment at least annually and whenever events or circumstances change that indicate impairment may have occurred. In 2015, the Company changed its annual testing date from December 31 to October 1. The Company believes this change in the method of applying an accounting principle is preferable, as it allows for a more robust fair value assessment. This change in annual testing date does not delay, accelerate, or avoid an impairment charge. A significant amount of judgment is involved in determining if an indicator of impairment has occurred. Such indicators may include, among others: a significant decline in the Company’s expected future cash flows; a sustained, significant decline in the Company’s stock price and market capitalization; a significant adverse change in legal factors or in the business climate of its segments; unanticipated competition; and slower growth rates. Any adverse change in these factors could have a significant impact on the recoverability of goodwill, the indefinite-lived intangible asset and the Company’s consolidated financial results.The company recorded an impairment charge of $143 for technology related industry accreditation and $1.4 million for goodwill in 2015 and 2014, respectively. Reportable segments are defined in Note 1 Basis of Presentation. The Company tests its goodwill for impairment at the reporting unit level, which is an operating segment or a segment that is one level below its operating segments. An operating segment is defined by ASC 280-10-50 as a component of an enterprise that earns revenue and incurs expenses, of which discrete financial information is available. During the second quarter of 2015, the Company began evaluating improvement strategies to reorganize, simplify and cut costs from operations through closer business integration which reduced the number of reporting units to four in 2015, while the 2014 operations had nine reporting units. The goodwill has been assigned to the reporting unit to which the value relates. Three of the Company's four reporting units have goodwill. The Company tests goodwill by estimating the fair value of the reporting unit using a discounted cash flow model and other valuation techniques, but may elect to perform a qualitative analysis. A quantitative analysis is used to determine an estimated fair value representing the amount at which a reporting unit could be bought or sold in a current transaction between willing parties on an arms-length basis. The estimated fair value of each reporting unit is derived using a discounted cash flow method based on market and reporting unit-specific assumptions, including estimated future revenues and expenses, weighted average cost of capital, capital expenditures, the useful life over which cash flows will occur and other assumptions which are considered reasonable and inherent in discounted cash flow analysis. A qualitative analysis is performed by assessing certain trends and factors, including projected market outlook and growth rates, forecasted and actual sales and operating profit margins, discount rates, industry data and other relevant qualitative factors. These trends and factors are compared to, and based on, the assumptions used in the most recent quantitative assessment. Indefinite life intangible assets consist primarily of trademarks. The fair value of these assets are determined using a royalty relief methodology similar to that employed when the associated assets were acquired, but using updated estimates of future sales, cash flows and profitability. The Company’s 2015 quantitative impairment test identified no impairment of goodwill or indefinite life intangibles. During the Company's 2014 annual impairment tests of goodwill and indefinite-lived intangible assets, management identified potential impairment. The Company's management then determined that, by use of quantitative methods for testing, the Bemag Transformer Inc. (“Bemag”) business unit assets were impaired and recognized an impairment charge of approximately $1.2 million related to goodwill and $0.2 million related to definite-lived intangible assets as the carrying value of the Bemag business unit was in excess of its fair value. See Note 8 - Goodwill and Other Intangible Assets for further information.
Foreign Currency Translation | Foreign Currency Translation The functional currency for the Companies foreign subsidiaries is the local currency in which the entity is located. The financial statements of all subsidiaries with a functional currency other than the U.S. dollar have been translated into U.S. dollars. All assets and liabilities of foreign operations are translated into U.S. dollars using year-end exchange rates, and all revenues and expenses are translated at weighted average rates during the respective period. The U.S. dollar results that arise from such translation, as well as exchange gains and losses on intercompany balances of a long-term investment nature, are included in the cumulative currency translation adjustments in accumulated other comprehensive income in stockholders’ equity. Gains and losses resulting from foreign currency transactions are included in earnings.
Income Taxes | Income Taxes The Company accounts for income taxes under the asset and liability method, based on the income tax laws and rates in the countries in which operations are conducted and income is earned. This approach requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax basis of assets and liabilities. Developing the provision for income taxes requires significant judgment and expertise in federal, international and state income tax laws, regulations and strategies, including the determination of deferred tax assets and liabilities and, if necessary, any valuation allowances that may be required for deferred tax assets. The Company records a valuation allowance to reduce its deferred tax assets to the amount that is more likely than not to be realized. The Company believes that the deferred tax assets recorded as of December 31, 2015 and 2014, is realizable through future reversals of existing taxable temporary differences and future taxable income. If the Company was to subsequently determine that it would be able to realize deferred tax assets in the future in excess of its net recorded amount, an adjustment to deferred tax assets would increase net income for the period in which such determination was made. The Company will continue to assess the adequacy of the valuation allowance on a quarterly basis. The Company’s judgments and tax filings are subject to audit by various taxing authorities. The objective of accounting for income taxes is to recognize the amount of taxes payable or refundable for the current year and deferred tax liabilities and assets for the future tax consequences or events that have been recognized in the Company’s financial statements or tax returns. The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position (see “Unrecognized Tax Benefits" below). Income tax related interest and penalties are grouped with interest expense on the consolidated statement of operations.
Unrecognized Tax Benefits | Unrecognized Tax Benefits The Company accounts for unrecognized tax benefits in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) "Income Taxes" ("ASC 740"). ASC 740 prescribes a recognition threshold that a tax position is required to meet before being recognized in the financial statements and provides guidance on de-recognition, measurement, classification, interest and penalties, accounting in interim periods, disclosure and transition issues. ASC 740 contains a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained upon ultimate settlement with a taxing authority, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon ultimate settlement. Additionally, ASC 740 requires the Company to accrue interest and related penalties, if applicable, on all tax positions for which reserves have been established consistent with jurisdictional tax laws. See Note 14 - Income Taxes.
Share-Based Payments | Share-Based Payments The Company accounts for share based payments in accordance with the provisions of FASB ASC 718 "Compensation - Stock Compensation" and accordingly recognizes in its financial statements share based payments at their fair value. In addition, it recognizes in the financial statements an expense based on the grant date fair value of stock options granted to employees and directors. The expense is recognized on a straight line basis over the expected option life while taking into account the vesting period and the offsetting credit is recorded in additional paid-in capital. Upon exercise of options, the consideration paid together with the amount previously recorded as additional paid-in capital is recognized as capital stock. The Company estimates its forfeiture rate in order to determine its compensation expense arising from stock based awards. The Company uses the Black-Scholes Merton option pricing model to determine the fair value of the options. Non-employee members of the Board of Directors are deemed to be employees for the purposes of recognizing share-based compensation expense.
Employee Benefit Plan | Employee Benefit Plan The Company sponsors a defined benefit plan as described in Note 15 - Pension Plan. The cost of pension benefits earned by employees is actuarially determined using the accumulated benefit method and a discount rate, used to measure interest cost on the accrued employee future benefit obligation, based on market interest rates on high-quality debt instruments with maturities that match the timing and benefits expected to be paid by the plan. Plan assets are valued using current market values and the expected return on plan assets is based on the net asset value of the plan assets. The costs that relate to employee current service are charged to income annually. The transitional obligation created upon adoption of the FASB ASC 715 "Compensation - Retirement Benefits" is amortized over the average remaining service period of employees. For a given year, unrecognized actuarial gains or losses are recognized into income if the unamortized balance at the beginning of the year is more than 10% of the greater of the plan asset or liability balance. Any unrecognized actuarial gain or loss in excess of this threshold is recognized in income over the remaining service period of the employees. The Company reflects the funded status of its defined pension plans as a net asset or net liability in its balance sheet, with an offsetting amount in accumulated other comprehensive income, and recognizes changes in that funded status in the year in which the changes occur through comprehensive income.
Inventories | Inventories Inventories are stated at the lower of cost or market using first-in, first-out (FIFO) or weighted-average methods and include the cost of materials, labor and manufacturing overhead. The Company uses estimates in determining the level of reserves required to state inventory at the lower of cost or market. The Company estimates are based on market activity levels, production requirements, the physical condition of products and technological innovation. Changes in any of these factors may result in adjustments to the carrying value of inventory. See Note 6.
Income (Loss) Per Share | Income (Loss) Per Share Basic income (loss) per share is computed by dividing the income (loss) for the period by the weighted average number of common shares outstanding during the period. Diluted income (loss) per share is computed by dividing the income (loss) for the period by the weighted average number of common and common equivalent shares outstanding during the period. (see Note 17 – Basic and Diluted Net Income (Loss) Per Share).
Fair Value Measurements | Fair Value Measurements FASB ASC 820 “Fair Value Measurement and Disclosure” applies to all assets and liabilities that are being measured and reported on a fair value basis. ASC 820 establishes a framework for measuring fair value in U.S GAAP, and expands disclosure about fair value measurements. ASC 820 enables the reader of the financial statements to assess the inputs used to develop those measurements by establishing a hierarchy for ranking the quality and reliability of the information used to determine fair values. ASC 820 requires that assets and liabilities carried at fair value be classified and disclosed in one of the following three categories: Level 1: Quoted market prices in active markets for identical assets or liabilities. Level 2: Observable market based inputs or unobservable inputs that are corroborated by market data. Level 3: Unobservable inputs that are not corroborated by market data. In determining the appropriate levels, the Company performs a detailed analysis of the assets and liabilities that are subject to ASC 820, consisting primarily of cash and cash equivalents, receivables, payables and debt instruments. At each reporting period, all assets and liabilities for which the fair value measurement is based on significant unobservable inputs are classified as Level 3. The fair value represents management’s best estimates based on a range of methodologies and assumptions. The carrying value of receivables and payables arising in the ordinary course of business approximate fair value because of the relatively short period of time between their origination and expected realization. These items have been classified as Level 1. The Company’s financial instruments consist primarily of cash and cash equivalents, receivables, payables and debt instruments. The carrying values of these financial instruments approximate their respective fair values as they are either short-term in nature or carry interest rates which are periodically adjusted to market rates. Unless otherwise indicated, the carrying value of these financial instruments approximates their fair market value.
Reclassification of Long-Term Debt | Reclassification of Long-Term Debt The financial statements included in this annual report have been prepared assuming that we will continue as a going concern, which contemplates the recoverability of assets and the satisfaction of liabilities in the normal course of business. Significant assumptions underlie this belief, including, among other things, that there will be no material adverse developments in our business, liquidity, capital requirements and that our credit facilities with our lender will remain available to us and will not need to be replaced. In addition, we did not duly pay and discharge our payroll tax obligations in a manner compliant with the covenant requirements of our U.S. Facilities. (see Note 5 – Other Expense). Based on these determinations, we began discussions with our lender and secured a waiver of defaults dated November 18, 2015 with respect to our U.S. credit agreement and our Canadian letter loan agreement, to suspend testing of the existing financial defaults until January 31, 2016 and to permit borrowings of up to $3.0 million by our Canadian subsidiary in order to provide financial support to our U.S. operations, subject to the satisfaction of new financial reporting requirements and other conditions. This waiver was subsequently extended to April 30, 2016, and the amount of borrowings increased up to $5.0 million by our Canadian subsidiary in order to provide financial assistance to our US operations. As a result of this noncompliance and expected future noncompliance with existing covenant requirements through March 31, 2017, all outstanding long-term debt with the lender will be classified as a current liability. On March 28, 2016 we executed a committed term sheet for a formal extension of our credit facilities from the Bank for Montreal to July 31, 2017. A formal amendment of the credit agreement is expected to be executed during the second quarter of 2016, with terms that will be consistent with those agreed upon in the committed term sheet. With the execution of the amendment to the credit agreement, portions of the credit facilities will be classified as long term indebtedness. This committed term sheet contains revised covenants and funding amounts that finance our cash requirements for anticipated operating activities, restructuring and integration plans, capital improvements and scheduled principal repayments of long-term debt.
Recent Accounting Pronouncements | Recent Accounting Pronouncements There have been no recent accounting pronouncements not yet adopted by the Company which would have a material impact on our financial statements. Revenue from Contracts with Customers. In May 2014, the FASB issued Accounting Standards Update No. 2014-09 (“ASU 2014-09”), which supersedes nearly all existing revenue recognition guidance under U.S. GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration to which an entity expects to be entitled for those goods or services. ASU 2014-09 defines a five step process to achieve this core principle and, in doing so, more judgment and estimates may be required within the revenue recognition process than are required under existing U.S. GAAP. In July 2015, the FASB made a decision to defer the effective date of the new standard for one year and permit early adoption as of the original effective date. The Company is currently evaluating the impact of its pending adoption of ASU 2014-09 on its consolidated financial statements and has not yet determined the method by which it will adopt the standard in 2018. Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share (or Its Equivalent). In May 2015, the FASB issued Accounting Standards Update (“ASU”) 2015-07, “Fair Value Measurement (Topic 820): Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share (or Its Equivalent)” (“ASU 2015-07”). The amendments apply to reporting entities that elect to measure the fair value of an investment using the net asset value (“NAV”) per share (or its equivalent) practical expedient. The amendments remove the requirement to categorize within the fair value hierarchy all investments for which fair value is measured using the NAV per share practical expedient. The amendments also remove the requirement to make certain disclosures for all investments that are eligible to be measured at fair value using the NAV per share practical expedient. Rather, those disclosures are limited to investments for which the entity has elected to measure the fair value using that practical expedient. The amendments in this ASU are effective for reporting periods beginning after December 15, 2015, with early adoption permitted. Entities should apply the amendments in this update retrospectively to all periods presented. As the Company measures certain defined benefit plan assets using the NAV practicable expedient, upon adoption of ASU 2015-07, the fair value of these plan assets will be removed from the fair value hierarchy in all periods presented in the Company’s Consolidated Financial Statements. The Company will continue to disclose information on these investments for which fair value is measured at NAV as a practical expedient. Simplifying the Measurement of Inventory. In July 2015, the FASB issued ASU No. 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory. This standard amends Topic 330, Inventory, which currently requires an entity to measure inventory at the lower of cost or market. Market could be replacement cost, net realizable value, or net realizable value less an approximately normal profit margin. When this standard is adopted, an entity should measure in scope inventory at the lower of cost and net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The amendments are effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. The Company is currently evaluating the impact on its consolidated financial statements. Simplifying the Accounting for Measurement-Period Adjustments. In September 2015, the FASB issued ASU No. 2015-16, This ASU eliminates the requirement for an acquirer in a business combination to account for measurement-period adjustments retrospectively. The ASU is effective for public business entities for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. Early adoption is permitted for any interim and annual financial statements that have not yet been issued. The ASU is applied prospectively to adjustments to provisional amounts that occur after the effective date. That is, the ASU applies to open measurement periods, regardless of the acquisition date. The Company is currently assessing the impact that adopting this new accounting guidance will have, if any, on its consolidated financial statements and footnotes disclosures. Balance Sheet Classification of Deferred Taxes. In November 2015, the FASB issued No. 2015-17, Income Taxes (Topic 740), which requires that deferred tax liabilities and assets be classified as non-current in a classified statement of financial position. The current requirement that deferred tax liabilities and assets of a tax-paying component of an entity be offset and presented as a single amount is not affected by ASU No. 2015-17. ASU No. 2015-17 is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years, with early adoption permitted. A reporting entity may apply the provisions of ASU No. 2015-17 prospectively or retrospectively to all prior periods presented in the financial statements. The Company retrospectively adopted ASU No. 2015-17 in 2015 and has reflected the impact in the current and prior years in its statement of financial position. Leases. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which requires, among other things, a lessee to recognize a liability representing future lease payments and a right-of-use asset representing its right to use the underlying asset for the lease term. For operating leases, a lessee will be required to recognize at inception a right-of-use asset and a lease liability equal to the net present value of the lease payments, with lease expense recognized over the lease term on a straight-line basis. For leases with a term of twelve months or less, ASU 2016-02 allows a reporting entity to make an accounting policy election to not recognize a right-of-use asset and a lease liability, and to recognize lease expense on a straight-line basis. ASU No. 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, with early adoption permitted. Upon adoption, a reporting entity should apply the provisions of ASU 2016-02 at the beginning of the earliest period presented using a modified retrospective approach, which includes certain optional practical expedients that an entity may elect to apply. The Company is evaluating the potential impact on its consolidated financial statements of adopting ASU 2016-02. In August 2014, the FASB issued Accounting Standards Update (“ASU”) 2014-15, “Presentation of Financial Statements – Going Concern (Subtopic 205-40)”. This ASU establishes accounting guidance about management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern or to provide related footnote disclosures. The amendments in this Update are effective for the annual period ending after December 15, 2016, and for annual periods and interim periods thereafter. Early application is permitted. The Company is evaluating the potential impact on its consolidated financial statements of adopting ASU 2014-15.
