| Significant Accounting Policies [Text Block] | Significant Accounting Policies Principles of Consolidation The consolidated financial statements of the Company have been prepared by management in accordance with accounting principles generally accepted in the United States of America (“GAAP”), applied on a basis consistent for all periods. These consolidated financial statements include the accounts of the Company and its subsidiaries, all of which are wholly owned. All intercompany balances and transactions have been appropriately eliminated in consolidation. Reclassifications Certain reclassifications have been made to prior periods’ amounts to conform to the current period’s presentation. Use of Estimates The preparation of the consolidated financial statements 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 consolidated financial statements and reported amounts of revenues and expenses during the reporting period. Significant areas requiring the use of management estimates relate to the determination of provisions for litigation claims; deferred revenue; allowance for doubtful receivables; inventory valuation; warranty provisions; deferred income taxes; and impairment assessments of goodwill, other indefinite-lived intangible assets and long-lived assets. Actual results could differ from these estimates. Foreign Currency Translation The financial statements of foreign subsidiaries, for which the functional currency is the local currency, are translated into U.S. dollars using the exchange rate at the consolidated balance sheet date for assets and liabilities and a weighted-average exchange rate during the year for revenue, expenses, gains and losses. Translation adjustments are recorded as other comprehensive income (loss) within shareholders’ equity. Gains or losses from foreign currency transactions are recognized in the consolidated statements of operations. Such transactions resulted in a minimal loss in 2016, and a loss of $1.7 million and $0.2 million for the years ended December 31, 2015 and 2014 , respectively. Cash Equivalents Highly liquid investments with insignificant interest rate risk and original maturities of three months or less, when purchased, are classified as cash equivalents. Cash equivalents are composed of money market funds. The carrying amounts approximate fair value due to the short maturities of these instruments. Accounts Receivable Accounts receivable is recorded at the invoiced amount and is non-interest bearing. We estimate our allowance for doubtful accounts based on an assessment of the collectability of specific accounts and the overall condition of the accounts receivable portfolio. When evaluating the adequacy of the allowance for doubtful accounts, we analyze specific trade and other receivables, historical bad debts, customer credits, customer concentrations, customer credit-worthiness, current economic trends and changes in customers’ payment terms and/or patterns. We review the allowance for doubtful accounts on a quarterly basis and record adjustments as considered necessary. Customer accounts are written-off against the allowance for doubtful accounts when an account is considered uncollectable. At both December 31, 2016 and 2015 , allowance for doubtful accounts of $1.6 million was recorded. Inventories Inventories are stated at the lower of cost or market using the first-in-first-out method. We assess the value of inventories periodically based upon numerous factors including, among others, expected product or material demand, current market conditions, technological obsolescence, current cost, and net realizable value. If necessary, we write down its inventory for obsolete or unmarketable inventory by an amount equal to the difference between the cost of the inventory and the estimated market value. Property and Equipment Property and equipment are recorded at cost. Depreciation expense is computed using the straight-line method. Leasehold improvements are depreciated over the shorter of the remaining estimated useful life of the asset or the term of the lease. Expenditures for normal maintenance and repair are charged to expense as incurred, and improvements are capitalized. Upon the sale or retirement of property or equipment, the asset cost and related accumulated depreciation are removed from the respective accounts and any gain or loss is included in the results of operations. Estimated useful lives are typically as follows: Building 40 years Machinery and equipment 3-5 years Furniture and fixtures 5 years Computer equipment and software 1-5 years Goodwill and Intangible Assets Goodwill represents the excess of consideration paid over the value assigned to the net tangible and identifiable intangible assets acquired. For intangible assets purchased in a business combination, the estimated fair values of the assets received are used to establish their recorded values. For intangible assets acquired in a non-monetary exchange, the estimated fair values of the assets transferred (or the estimated fair values of the assets received, if more clearly evident) are used to establish their recorded values. Valuation techniques consistent with the market approach, income approach and/or cost approach are used to measure fair value. Purchased intangible assets are amortized on a straight-line basis over their economic lives of 25 years for channel partner relationships, four to nine years for developed technology, eight years for capitalized development costs, and five to 25 years for customer relationships as this method most closely reflects the pattern in which the economic benefits of the assets will be consumed. Impairment of Goodwill, Other Indefinite-Lived Intangible Assets and Long-Lived Assets Goodwill and other indefinite-lived assets are tested for impairment on an annual basis at December 31, or more frequently if there are indicators of impairment. Triggering events for impairment reviews may be indicators such as adverse industry or economic trends, restructuring actions, lower projections of profitability, or a sustained decline in our market capitalization. Other indefinite-lived intangible assets are quantitatively assessed for impairment, if necessary, by comparing their estimated fair values to their carrying values. If the carrying value exceeds the fair value, the difference is recorded as an impairment. See Note 6 - Intangible Assets and Goodwill for further information on impairment. Long-lived assets, such as property and equipment and intangible assets subject to amortization, are reviewed for recoverability whenever events or changes in circumstances indicate the carrying value may not be recoverable. Our consideration includes, but is not limited to: (i) significant under-performance relative to historical or projected future operating results; (ii) significant changes in the manner of use of the assets or the strategy for the Company’s overall business; (iii) significant decrease in the market value of the assets; and (iv) significant negative industry or economic trends. When the carrying value is not considered recoverable, an impairment loss for the amount by which the carrying value of a long-lived asset exceeds its fair value is recognized, with an offsetting reduction in the carrying value of the related asset. See Note 6 - Intangible Assets and Goodwill for further information on impairment. Revenue Recognition Revenue from sales of products is recognized when persuasive evidence of an arrangement exists, the price is fixed or determinable, collectability is reasonably assured and delivery has occurred. Under this policy, revenue on direct product sales, excluding sales to distributors, is recognized upon shipment of products to customers. These customers are not entitled to any specific right of return or price protection, except for any defective product that may be returned under our standard product warranty. Revenue from services, such as extended product warranties, are deferred and recognized over the period of the service agreement. Title and risk of loss transfer to the customer when the product leaves the Company’s dock, except for one subsidiary where title and risk of loss transfer to the customer when the product arrives at the customer’s location. Product sales to distribution customers are subject to certain rights of return, stock rotation privileges and price protection. Because we are unable to estimate its exposure for returned product or price adjustments, revenue from shipments to these customers is not recognized until the related products are in turn shipped to the ultimate customer by the distributor. For products for which software is more than an incidental component, we recognize revenue in accordance with current authoritative guidance for software revenue recognition. The Company enters into revenue arrangements that may consist of multiple deliverables of its product and service offerings, such as for sales of hardware devices and extended warranty services. The Company allocates revenue to deliverables in multiple element arrangements based on relative selling prices. The Company determines its vendor-specific objective evidence (“VSOE”) based on its normal pricing and discounting practices for the specific product or service when sold separately. When the Company is not able to establish VSOE for all deliverables in an arrangement with multiple elements, the Company attempts to determine the selling price of each element based on third party evidence of selling price, or based on the Company’s actual historical selling prices of similar items, whichever management believes provides the most reliable estimate of expected selling prices. Warranty and Extended Warranty We record a provision for standard warranties provided with all products. If future actual costs to repair were to differ significantly from estimates, the impact of these unforeseen costs or cost reductions would be recorded in subsequent periods. Separately priced extended on-site warranties and service contracts are offered for sale to customers on all product lines. We contract with third party service providers to provide service relating to on-site warranties and service contracts. Extended warranty and service contract revenue and amounts paid in advance to outside service organizations are deferred and recognized as service revenue and cost of service, respectively, over the period of the service agreement. Shipping and Handling Amounts billed to customers for shipping and handling are included in product revenue, and costs incurred related to shipping and handling are included in cost of product revenue. Advertising Costs Advertising costs are expensed as incurred. Advertising expenses were $2.5 million , $1.6 million and $0.7 million for the years ended December 31, 2016, 2015 and 2014 , respectively. Research and Development Costs Research and development expenses include payroll, employee benefits, share-based compensation expense, and other headcount-related expenses associated with product development. Research and development expenses also include third party development and programming costs, localization costs incurred to translate software for international markets, and the amortization of purchased software code and services content. Such costs related to software development are included in research and development expense until the point that technological feasibility is reached, which for our software products, is generally shortly before the products are released to manufacturing. Once technological feasibility is reached, such costs are capitalized and amortized to cost of revenue over the estimated lives of the products. During 2016 , no development costs were capitalized. During 2015 and 2014 , the Company capitalized $0.1 million and $1.8 million , respectively, of development costs. Segment Information We report segment data based on the management approach. The management approach designates the internal reporting that is used by management for making operating and investment decisions and evaluating performance as the source of our reportable segments. We use one measurement of profitability and do not disaggregate our business for internal reporting. We operate in one segment providing data management, and desktop and application virtualization solutions for small and medium businesses and distributed enterprises. We disclose information about products and services, geographic areas, and major customers. Income Taxes We provide for income taxes utilizing the asset and liability approach of accounting for income taxes. Under this approach, deferred taxes represent the future tax consequences expected to occur when the reported amounts of assets and liabilities are recovered or paid. The provision for income taxes generally represents income taxes paid or payable for the current year plus the change in deferred taxes during the year. Deferred taxes result from differences between the financial and tax basis of our assets and liabilities and are adjusted for changes in tax rates and tax laws when changes are enacted. Valuation allowances are recorded to reduce deferred tax assets when a judgment is made that it is considered more likely than not that a tax benefit will not be realized. A decision to record a valuation allowance results in an increase in income tax expense or a decrease in income tax benefit. If the valuation allowance is released in a future period, income tax expense will be reduced accordingly. The calculation of tax liabilities involves evaluating uncertainties in the application of complex global tax regulations. The impact of an uncertain income tax position is recognized at the largest amount that is “more likely than not” to be sustained upon audit by the relevant taxing authority. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained. If the estimate of tax liabilities proves to be less than the ultimate assessment, a further charge to expense would result. Comprehensive Loss Comprehensive loss and its components encompasses all changes in equity other than those arising from transactions with shareholders, including net loss and foreign currency translation adjustments, and is disclosed in a separate consolidated statement of comprehensive loss. Concentration of Credit Risks Financial instruments that potentially subject us to concentrations of credit risk consist primarily of trade accounts receivable, which are generally not collateralized. To reduce credit risk, we perform ongoing credit evaluations of its customers and maintain allowances for potential credit losses for estimated bad debt losses. At December 31, 2016 and 2015, there was one customer that made up 13.0% and 17.5% , respectively, of accounts receivable. There were no customers for the years ended December 31, 2016, 2015 and 2014 that made up 10% or more of net revenue. Share-based Compensation We account for share-based awards, and similar equity instruments, granted to employees, non-employee directors, and consultants under the fair value method. Share-based compensation award types include stock options and restricted stock. We use the Black-Scholes option pricing model to estimate the fair value of option awards on the measurement date, which generally is the date of grant. The expense is recognized over the requisite service period (usually the vesting period) for the estimated number of instruments for which service is expected to be rendered. The fair value of restricted stock units (“RSUs”) is estimated based on the market value of the Company’s common shares on the date of grant. The fair value of options granted to non-employees is estimated at the measurement date using the Black-Scholes option pricing model and the unvested options remeasured at each reporting date, with changes in fair value recognized in expense in the consolidated statement of operations. Share-based compensation expense for options with graded vesting is recognized pursuant to an accelerated method. Share-based compensation expense for RSUs is recognized over the vesting period using the straight-line method. Share-based compensation expense for an award with performance conditions is recognized when the achievement of such performance conditions are determined to be probable. If the outcome of such performance condition is not determined to be probable or is not met, no compensation expense is recognized and any previously recognized compensation expense is reversed. We have not recognized, and do not expect to recognize in the near future, any tax benefit related to share-based compensation cost as a result of the full valuation allowance of our net deferred tax assets and its net operating loss carryforward. Recently Issued Accounting Pronouncements From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (“FASB”) that are adopted by the Company as of the specified effective date. If not discussed, the Company believes that the impact of recently issued standards, which are not yet effective, will not have a material impact on the Company’s consolidated financial statements upon adoption. In January 2017, the FASB issued Accounting Standards Update (“ASU”) No. 2017-04, Intangibles - Goodwill and Other (Topic 350) - Simplifying the Test for Goodwill Impairment (“ASU 2017-04”) . ASU 2017-04 simplifies the subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test. An entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount, and recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value, if applicable. The loss In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”). ASU 2016-15 addresses eight cash flow classification issues and how they should be reported in the statement of cash flows. ASU 2016-15 is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. Early adoption is permitted for all companies in any interim or annual period. We are currently evaluating the effect that the updated standard will have on our consolidated financial position, results of operations or cash flows. In April 2016, the FASB issued ASU No. 2016-10, Revenue From Contracts With Customers (Topic 606): Identifying Performance Obligations and Licensing (“ASU 2016-10”). ASU 2016-10 clarifies the following two aspects of Topic 606: identifying performance obligations and the licensing implementation guidance, while retaining the related principles for those areas. The effective date of ASU 2016-10 will coincide with ASU 2014-09 and, as described below, ASU 2014-09 will be effective for annual reporting periods beginning after December 15, 2017. The impact on our consolidated financial position, results of operations or cash flows as a result of the adoption of ASU 2016-10 has not yet been determined. In March 2016, the FASB issued ASU No. 2016-08, Revenue From Contracts With Customers (Topic 606): Principal Versus Agent Considerations (Reporting Revenue Gross Versus Net) (“ASU 2016-08”). ASU 2016-08 amends the principal-versus-agent implementation guidance in ASU 2014-09. ASU 2016-08 clarifies the principal-versus-agent guidance in Topic 606 and requires an entity to determine whether the nature of its promise to provide goods or services to a customer is performed in a principal or agent capacity and to recognize revenue in a gross or net manner based on its principal/agent designation. The effective date of ASU 2016-08 will coincide with ASU 2014-09 and, as described below, ASU 2014-09 will be effective for annual reporting periods beginning after December 15, 2017. The impact on our consolidated financial position, results of operations or cash flows as a result of the adoption of ASU 2016-08 has not yet been determined. In February 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718) (“ASU 2016-09”). ASU 2016-09 simplifies the accounting for several aspects of the accounting for share-based payment transactions including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. ASU 2016-09 is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early adoption is permitted for any entity in any interim or annual period. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. An entity that elects early adoption must adopt all of the amendments in the same period. We have not yet selected a transition method and we are still evaluating any potential impact of the adoption of ASU 2016-09 may have on our consolidated financial position, results of operations or cash flows. In February 2016, the FASB issued ASU 2016-02 Leases (Topic 842) (“ASU 2016-02”). ASU 2016-02 increases transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and requires disclosing key information about leasing arrangements. ASU 2016-02 is effective for reporting periods beginning after December 15, 2018, with early adoption permitted. An entity will be required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. We are still evaluating any potential impact of the adoption of ASU 2016-02 may have on our consolidated financial position, results of operations or cash flows. In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory . ASU 2015-11 requires that for entities that measure inventory using the first-in, first-out method, inventory should be measured at the lower of cost and net realizable value. Topic 330, Inventory , 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. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. ASU 2015-11 is effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. The amendments should be applied prospectively with earlier application permitted as of the beginning of an interim or annual reporting period. The impact on our consolidated financial position, results of operations or cash flows as a result of the adoption of ASU 2015-11 has not yet been determined. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers. ASU 2014-09 outlines a single comprehensive model for accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance. ASU 2014-09 requires an entity to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 as amended is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. Entities can transition to the standard either retrospectively or as a cumulative-effect adjustment as of the date of adoption. We have not yet selected a transition method and the impact on our consolidated financial position, results of operations or cash flows as a result of the adoption of ASU 2014-09 has not yet been determined. Recently Adopted Accounting Pronouncements In November 2015, the FASB issued ASU 2015-17, Balance Sheet Classification of Deferred Taxes (“ASU 2015-17”). ASU 2015-17 requires companies to classify all deferred tax assets and liabilities as non-current on the balance sheet instead of separating deferred taxes into current and non-current amounts. For public business entities, the guidance is effective for financial statements issued for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Early adoption is permitted for all companies in any interim or annual period. The guidance may be adopted on either a prospective or retrospective basis. We have adopted this guidance prospectively as of December 31, 2016. Therefore, prior periods have not been adjusted to reflect this adoption. This change in accounting principle does not change our consolidated financial position, results of operations or cash flows. In September 2015, the FASB issued ASU No. 2015-16, Business Combinations (Topic 805). ASU No. 2015-16 requires that an acquirer recognizes adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. This guidance requires that the acquirer record, in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change in provisional amounts, calculated as if the accounting had been completed at the acquisition date. This guidance requires an entity to present separately on the face of the income statement or disclose in the notes the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. ASU No. 2015-16 is effective beginning fiscal years beginning after December 15, 2015, including interim periods within those fiscal years. The impact on our consolidated financial position, results of operations or cash flows as a result of the adoption of ASU 2015-16 was not material. In April 2015, the FASB issued ASU 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from that debt liability, consistent with the presentation of a debt discount. The recognition and measurement guidance for debt issuance costs is not affected by ASU 2015-03. ASU 2015-03 is effective fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. Early application is permitted. The impact on our consolidated financial position, results of operations or cash flows as a result of the adoption of ASU 2015-03 was not material. In August 2014, the FASB issued ASU 2014-15, Presentation of Financial Statements - Going Concern. ASU 2014-15 provides that in connection with preparing financial statements for each annual and interim reporting period, an entity’s management should evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the financial statements are issued (or within one year after the date that the financial statements are available to be issued when applicable). ASU 2014-15 will be effective for the annual reporting periods ending after December 15, 2016, and for annual and interim periods thereafter. Early application is permitted. The impact on our consolidated financial disclosures as a result of the adoption of ASU 2014-15 was not material. |
