Organization and Business	Dec. 31, 2017
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	Organization and Business Sphere 3D Corp. (the “Company”) was incorporated under the Business Corporations Act (Ontario) on May 2, 2007 as T.B. Mining Ventures Inc. On March 24, 2015, the Company completed a short-form amalgamation with a wholly-owned subsidiary. In connection with the short-form amalgamation, the Company changed its name to “Sphere 3D Corp.” The Company delivers data management, and desktop and application virtualization solutions through hybrid cloud, cloud and on premise implementations by its global reseller network. The Company achieves this through a combination of containerized applications, virtual desktops, virtual storage and physical hyper-converged platforms. The Company’s products allow organizations to deploy a combination of public, private or hybrid cloud strategies while backing them up with the latest storage solutions. The Company has a portfolio of brands including RDX^®,Glassware 2.0™, SnapCLOUD^®, SnapServer^®, SnapSync™, NEO^®, and V3^®. Related Party Share Purchase Agreement On February 20, 2018, the Company, Overland Storage, Inc., a California corporation and a wholly owned subsidiary of the Company (“Overland”), and Silicon Valley Technology Partners LLC, a Delaware limited liability company established and controlled by Eric Kelly, the Company’s Chief Executive Officer and Chairman of the Board of Directors (the “Purchaser”) entered into a share purchase agreement (the “Purchase Agreement”), pursuant to which, among other things, and subject to certain closing conditions, the Company will sell to Purchaser all of the issued and outstanding shares of capital stock of Overland for $45.0 million (the “Purchase Price”), subject to a working capital adjustment (the “Share Purchase”). The net proceeds from the Share Purchase will be used to repay: (i) the Company’s outstanding obligations under its Credit Agreement with Opus Bank; (ii) its outstanding obligations under the related party convertible note with FBC Holdings S.a.r.l. (“FBC Holdings”); and (iii) its related party subordinated promissory note with MF Ventures, LLC. The Special Committee of the Board of Directors of the Company and the Board of Directors of the Company (with Eric Kelly recusing himself) unanimously approved the entry into the Purchase Agreement by the Company. Under the terms of the Purchase Agreement, the Share Purchase is contingent upon, and Purchaser must use its best efforts to arrange for, debt and/or equity financing in an amount at least equal to the Purchase Price in order to consummate the Share Purchase (the “Financing”). In addition, the Company must use commercially reasonable efforts to provide all cooperation reasonably requested by Purchaser regarding the Financing. Until the Financing is committed in accordance with a Contingency Termination Event (as defined below), the Company is free to solicit and negotiate other offers to purchase the Company, Overland or any or all of their assets and has the right to terminate the Purchase Agreement for any or no reason without penalty (subject to the expense reimbursement provisions described below). The closing of the Share Purchase and of the other transactions contemplated by the Purchase Agreement are subject to (i) the adoption of the Purchase Agreement by the affirmative vote of the holders of (a) at least 66 2/3% of the outstanding common shares of the Company cast in person or by proxy at the special meeting of shareholders and (b) a majority of the votes cast by certain “minority shareholders” in person or by proxy at the special meeting of shareholders (the “Shareholder Approval”) and (ii) the transfer by the Company of (a) the businesses of (x) Unified ConneXions, Inc. and (y) HVE ConneXions, LLC (including the provision of information technology consulting services and hardware solutions around cloud computing, data storage and server virtualization to corporate, government, and educational institutions), and (b) the SNAP network attached storage business to a subsidiary of the Company other than Overland or a subsidiary of Overland. The closing of the Share Purchase and of the other transactions contemplated by the Purchase Agreement are also subject to various other conditions, including the consummation of the Financing, the absence of any order, statute, rule, regulation, executive order, decree or injunction issued by any governmental entity prohibiting the Share Purchase, the absence of a pending claim, suit, action or proceeding material claims seeking to prohibit the Share Purchase, the accuracy of the representations and warranties contained in the Purchase Agreement, compliance with the covenants and agreements contained in the Purchase Agreement in all material respects, and the absence of a material adverse effect on either the Company or Overland. The Company has made customary representations, warranties and covenants in the Purchase Agreement, including, among others, covenants (i) to conduct its business in the ordinary course during the period between the execution of the Purchaser Agreement and the closing of the Share Purchase, (ii) not to engage in specified types of transactions during this period unless agreed to in writing by Purchaser, (iii) to convene and hold a meeting of its shareholders for the purpose of obtaining the Shareholder Approval and (iv) subject to certain exceptions and only following the occurrence of the Contingency Termination Event (as defined below), not to solicit and negotiate other offers to purchase the Company, Overland or any or all of their assets or to withdraw, modify or qualify in a manner adverse to Purchaser the recommendation of the Board that the Company’s shareholders vote in favor of approving the Share Purchase. The Company has also agreed to indemnification provisions in favor of Purchaser that are customary for transactions of this type. Prior to the (i) execution and delivery of financing commitments in forms reasonably acceptable to the Company, which provide, among other things, for commitments from financing sources sufficient to pay the Purchase Price in the Share Purchase, (ii) execution and delivery by Purchaser of an irrevocable waiver in a form reasonably acceptable to the Company waiving Purchaser’s condition to the obligation to close the Share Purchase that the Financing has been received and (iii) an executed certificate delivered by Purchaser to the Company regarding the accuracy of certain representations regarding the Financing (the “Contingency Termination Event”), the Company has the right to terminate the Purchase Agreement for any reason or for no reason. The Purchase Agreement also provides that, upon such termination of the Purchase Agreement by the Company, the Company has agreed to reimburse Purchaser up to approximately $350,000 for the reasonable and documented out-of-pocket expenses incurred by the Purchaser and the sources for the Financing in connection with the negotiation, execution and performance of the Purchase Agreement and the transactions contemplated thereby, as well as the fees and expenses of the Purchaser's outside counsel. In addition, the Purchase Agreement contains certain other termination rights, including, following the occurrence of the Contingency Termination Event, the right of the Company to terminate the Purchase Agreement under specified circumstances to accept an unsolicited superior proposal from a third party. The Purchase Agreement provides that, following the occurrence of the Contingency Termination Event and upon termination of the Purchase Agreement by the Company under specified circumstances (including termination by the Company to accept a superior proposal) or by Purchaser under specified circumstances, a termination fee equal to the lesser of (i) $1.0 million and (ii) the amount of Purchaser’s reasonable fees and expenses in connection with the negotiation, execution and performance of the Purchase Agreement (including the amount that the Purchaser must pay or reimburse to the sources for the Financing) will be payable by the Company to the Purchaser. Such termination fee is also payable following the occurrence of the Contingency Termination Event under certain other specified circumstances set forth in the Purchase Agreement. The Purchase Agreement also provides that each party to the Purchase Agreement may compel the other party or parties thereto to specifically perform its or their obligations under the Purchase Agreement. However, if the Purchase Agreement is terminated such that the Company termination fee becomes payable, the Purchaser will be precluded from any other remedy against the Company or Overland, including expense reimbursement and specific performance. Further, if the Purchase Agreement is terminated such that the expense reimbursement becomes payable, the Purchaser will be precluded from any other remedy against the Company or Overland, including the Company termination fee and specific performance. Subject to certain exceptions and limitations, either party may terminate the Purchase Agreement if the Share Purchase is not consummated by August 19, 2018. Management has projected that cash on hand will not be sufficient to allow the Company to continue operations beyond March 31, 2018 if the Company is unable to amend, refinance, or pay off its debt and credit facilities. In February 2018, the Company entered into a Purchase Agreement. If the transactions contemplated by the Purchase Agreement are consummated, the Company expects that the proceeds to be received by the Company would be sufficient to pay off its outstanding debt and credit facilities. The Company anticipates to hold a special shareholder meeting in April 2018 to seek shareholder approval for the Share Purchase and, subject to the receipt of requisite shareholder approval, anticipates the transaction will close shortly thereafter. There can be no guarantee that we will be able to raise additional funds or amend or refinance our debt and credit facilities on favorable terms or at all, nor can there be any guarantee that the Company’s shareholders will approve the Share Purchase. Significant changes from the Company’s current forecasts, including but not limited to: (i) failure to comply with the financial covenants in its credit facilities; (ii) shortfalls from projected sales levels; (iii) unexpected increases in product costs; (iv) increases in operating costs; (v) changes in the historical timing of collecting accounts receivable; and (vi) inability to maintain compliance with the requirements of the NASDAQ Capital Market and/or inability to maintain listing with the NASDAQ Capital Market could have a material adverse impact on the Company’s ability to access the level of funding necessary to continue its operations at current levels. If any of these events occurs or the Company is unable to generate sufficient cash from operations or financing sources, the Company may be forced to liquidate assets where possible and/or curtail, suspend or cease planned programs or operations generally or possibly seek bankruptcy protection, which would have a material adverse effect on the Company’s business, results of operations, financial position and liquidity. The Company incurred losses from operations and negative cash flows from operating activities for the 12 months ended December 31, 2017, and such losses might continue for a period of time. Based upon the Company's current expectations and projections for the next year, the Company believes that it may not have sufficient liquidity necessary to sustain operations beyond March 31, 2018 due to the maturity dates of the existing debt facilities. These factors, among others, raise doubt that the Company will be able to continue as a going concern. The accompanying consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. Reverse Stock Split On July 5, 2017, the Board of Directors of the Company authorized a share consolidation (also known as a reverse stock split) of the Company’s issued and outstanding common shares at a ratio of 1-for-25, which became effective on July 11, 2017. All share and per share amounts in the accompanying consolidated financial statements and the notes thereto have been restated for all periods to reflect the share consolidation.

Accounting Policies [Abstract]

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.

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 impairment assessments of goodwill, other indefinite-lived intangible assets and long-lived assets; deferred revenue; allowance for doubtful receivables; inventory valuation; warranty provisions; deferred income taxes; and litigation claims. 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 gain of $0.9 million in 2017 and a minimal loss in 2016.

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 December 31, 2017 and 2016, allowance for doubtful accounts of $1.7 million and $1.6 million, respectively, was recorded.

Inventories

Inventories are stated at the lower of cost and net realizable value using the first-in-first-out method. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. 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 net realizable 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 six to 25 years for channel partner relationships, three to nine years for developed technology, three to eight years for capitalized development costs, and two 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, Intangible Assets and Long-Lived Assets

Goodwill and intangible 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. 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.

Long-lived assets 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.

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.

Depending on delivery terms, title and risk of loss transfer to the customer when the product leaves the Company’s dock, or 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.

In limited circumstances where a customer is unable to accept shipment and requests products be delivered to, and stored on, the Company’s premises, revenue is recognized when: (i) the customer has accepted risk of loss and acknowledged passage of title to the goods (ii) the customer has made a fixed commitment to purchase the products, (iii) the customer has requested delayed delivery and storage of the products, (iv) there is an agreed schedule for shipment of products to the customer within a reasonable period of time, (v) the Company has no specific performance obligation such that the earnings process for the products, as a unit of accounting, is not complete, (vi) the goods are segregated from the inventory and not available to fill other orders, (vii) the product is complete, ready for shipment and accepted by the customer, and (viii) all other criteria above for revenue recognition have been met.

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 determines 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 $1.5 million and $2.5 million for the years ended December 31, 2017 and 2016, 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 2017 and 2016, no development costs were capitalized.

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, 2017 and 2016, there was one customer that made up 12.3% and 13.0%, respectively, of accounts receivable. There were no customers for the years ended December 31, 2017 and 2016 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. Forfeitures are recognized in share-based compensation expense as they occur.

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 July 2017, the FASB issued Accounting Standards Update (“ASU”) No. 2017-11, Earnings Per Share (Topic 260); Distinguishing Liabilities from Equity (Topic 480); Derivatives and Hedging (Topic 815) (“ASU 2017-11”). The update changes the classification of certain equity-linked financial instruments (or embedded features) with down round features. The update also clarifies existing disclosure requirements for equity-classified instruments. The update is effective retrospectively for annual reporting periods beginning after December 15, 2018, 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 ASU 2017-11 will have on our consolidated financial statements and related disclosures.

In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350) - Simplifying the Test for Goodwill Impairment (“ASU 2017-04”). The update 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 recognized should not exceed the total amount of goodwill allocated to the reporting unit. The same impairment test also applies to any reporting unit with a zero or negative carrying amount. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. The update is effective for annual reporting periods, including interim periods, beginning after December 15, 2019, on a prospective basis. Early adoption is permitted for interim or annual goodwill impairment tests performed after January 1, 2017. We do not expect the adoption of ASU 2017-04 to have a material effect on our consolidated financial statements and related disclosures.

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”). The update addresses eight cash flow classification issues and how they should be reported in the statement of cash flows. The update 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 ASU 2016-15 will have on our consolidated financial statements and related disclosures.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) (“ASU 2016-02”). The update 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. The update 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 currently evaluating the effect that ASU 2016-02 will have on our consolidated financial statements and related disclosures.

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”). In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606). In March, April, May and December 2016, the FASB issued additional guidance related to Topic 606. The new standard will supersede nearly all existing revenue recognition guidance. Under Topic 606, an entity is required 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. Topic 606 defines a five-step process in order to achieve this core principle, which may require the use of judgment and estimates, and also requires expanded qualitative and quantitative disclosures relating to the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers, including significant judgments and estimates used. The new standard permits adoption either by using (i) a full retrospective approach for all periods presented in the period of adoption or (ii) a modified retrospective approach where the new standard is applied in the financial statements starting with the year of adoption. We plan to adopt the new standard effective January 1, 2018 using the modified retrospective approach. The Company expects the adoption of the new standard will result in the recognition of revenues generally upon shipment (sell-in basis) for sales of products to certain customers which are currently being recognized on a sell-through basis. The Company estimates the adoption of the new standard under the modified retrospective method to result in a cumulative adjustment reducing our accumulated deficit by approximately $0.3 million. Additionally, as we continue to assess the new standard along with industry trends and additional interpretive guidance, we may adjust our adoption accordingly.

Recently Adopted Accounting Pronouncements

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. The update is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. The Company adopted ASU 2016-09 effective January 1, 2017. The impact on our consolidated financial statements and related disclosures was not material.

In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory (“ASU 2015-11”). The update 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. The update 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 Company adopted ASU 2015-11 effective January 1, 2017. The impact on our consolidated financial statements and related disclosures was not material.

Business Combination

UCX and HVE Acquisition

In December 2016, the Company acquired 19.9% of the outstanding equity interests of Unified ConneXions, Inc. (“UCX”) and HVE ConneXions, LLC (“HVE”) for the purchase price of $1.5 million. The Company issued 157,894 shares of its common shares in satisfaction of payment. In January 2017, the Company completed its acquisition of all of the remaining outstanding equity interests of UCX and HVE, for $1.1 million in cash and issued 88,235 common shares with an approximate value of $0.3 million. In 2017, the Company recognized a $1.1 million loss, included in other expense, as a result of the remeasurement to fair value the equity interest held immediately before the business combination. The valuation was based on the Company’s private placement completed as of January 26, 2017.

UCX and HVE provide information technology consulting services and hardware solutions around cloud computing, data storage and server virtualization to corporate, government, and educational institutions primarily in the southern central United States. By adding UCX’s technologies, professional services and engineering talent, and HVE’s products, engineering and virtualization expertise, the Company intends to expand its virtualization offerings as well as enhance its ability to accelerate the delivery of hybrid cloud solutions to customers. We incurred acquisition related expenses of $34,000 which consisted primarily of due diligence, legal and other one-time charges and are included in general and administrative expense in the consolidated statements of operations.

A summary of the estimated fair values of the assets acquired and liabilities assumed as of the closing date were as follows (in thousands):



Cash	$	49
Accounts receivable	582
Inventory	206

Total identifiable assets acquired	2,142
Accounts payable and accrued liabilities	(359		)
Deferred revenue	(518		)
Net identifiable assets acquired	1,265
Goodwill	522
Net assets acquired	$	1,787

Goodwill is primarily comprised of a trained an assembled workforce. The fair value estimates for the assets acquired and liabilities assumed for the acquisition were based on estimates and analysis, including work performed by third party valuation specialists. The goodwill recognized upon acquisition is not deductible for tax purposes.

The results of operations related to this acquisition have been included in our consolidated statements of operations from the acquisition date. Pro forma results of operations have not been presented because at this time it is impracticable to provide as the information is not available at the level of detail required.

The identified intangible assets as of the date of acquisition consisted of the following (in thousands):



	Estimated Fair Value		Weighted- Average Useful Life (years)
Channel partner relationships	$	730	6.0

Impairments

In 2017, primarily as a result of the Company’s change in revenue projection for its Snap product line, it was determined the carrying value of indefinite-lived intangible assets exceeded its estimated fair value. In measuring fair value, the Company used income and market approaches. The Company compared the indicated fair value to the carrying value of its indefinite-lived assets, and as a result of the analysis, an impairment charge of $2.2 million was recorded to indefinite-lived trade names for the year ended December 31, 2017. In addition, the Company recorded an impairment of $0.3 million related to developed technology for the year ended December 31, 2017.

In 2016, as a result of the Company’s declining market capitalization it was determined the carrying value exceeded its estimated fair value. In measuring fair value, the Company used income and market approaches. The Company compared the indicated fair value to the carrying value of its indefinite-lived assets, and as a result of the analysis, an impairment charge of $1.2 million was recorded to indefinite-lived trade names for the year ended December 31, 2016. In addition, the Company compared the implied fair value of the goodwill to the carrying value of the goodwill, and as a result of the analysis, an impairment charge of $33.2 million was recorded for the year ended December 31, 2016.

- Definition

The entire disclosure for the aggregate amount of goodwill and a description of intangible assets, which may include (a) for amortizable intangible assets (also referred to as finite-lived intangible assets), the carrying amount, the amount of any significant residual value, and the weighted-average amortization period, (b) for intangible assets not subject to amortization (also referred to as indefinite-lived intangible assets), the carrying amount, and (c) the amount of research and development assets acquired and written off in the period, including the line item in the income statement in which the amounts written off are aggregated, if not readily apparent from the income statement. Also discloses (a) for amortizable intangibles assets in total and by major class, the gross carrying amount and accumulated amortization, the total amortization expense for the period, and the estimated aggregate amortization expense for each of the five succeeding fiscal years, (b) for intangible assets not subject to amortization the carrying amount in total and by major class, and (c) for goodwill, in total and for each reportable segment, the changes in the carrying amount of goodwill during the period (including the aggregate amount of goodwill acquired, the aggregate amount of impairment losses recognized, and the amount of goodwill included in the gain (loss) on disposal of a reporting unit). If any part of goodwill has not been allocated to a reportable segment, discloses the unallocated amount and the reasons for not allocating. For each impairment loss recognized related to an intangible asset (excluding goodwill), discloses: (a) a description of the impaired intangible asset and the facts and circumstances leading to the impairment, (b) the amount of the impairment loss and the method for determining fair value, (c) the caption in the income statement or the statement of activities in which the impairment loss is aggregated, and (d) the segment in which the impaired intangible asset is reported. For each goodwill impairment loss recognized, discloses: (a) a description of the facts and circumstances leading to the impairment, (b) the amount of the impairment loss and the method of determining the fair value of the associated reporting unit, and (c) if a recognized impairment loss is an estimate not finalized and the reasons why the estimate is not final. May also disclose the nature and amount of any significant adjustments made to a previous estimate of an impairment loss.

Debt Disclosure [Abstract]
Debt Disclosure [Text Block]	Debt Related Party Convertible Note In December 2014, in connection with the acquisition of Overland, the existing debt of Overland and the remaining debt of the Company were amended and restated into a $19.5 million convertible note held by FBC Holdings. In April 2016, the Company modified its convertible note with FBC Holdings, pursuant to which the holder made an additional advance and principal amount under the convertible note amount was increased to $24.5 million. The convertible note is scheduled to mature March 31, 2018 and bears interest at an 8.0% simple annual interest rate, payable semi-annually. The obligations under the convertible note are secured by substantially all assets of the Company. At December 31, 2017, the Company had $24.4 million, net of unamortized debt costs of $0.1 million, outstanding on the convertible note. The Company has the option to pay accrued and outstanding interest either entirely in cash or common shares. If the Company choses to pay the interest in common shares, the calculation is based upon the number of common shares that may be issued as payment of interest on the convertible note and will be determined by dividing the amount of interest due by current market price as defined in the convertible note agreement. For the years ended December 31, 2017 and 2016, the Company issued 586,298 and 168,594 common shares, respectively, for the settlement of accrued interest expense. In November 2015, the convertible note’s conversion price was adjusted to $75.00 per share. In February 2016, in connection with the November 2015 modification and certain specified terms, the Company issued to the holder of the convertible note a warrant to purchase 20,000 common shares of the Company at a price of $40.50. At the option of the Company, the convertible note is convertible into common shares at the conversion price at any time that the weighted average trading price for the common shares exceeds 150% of the conversion price (i.e. exceeds $112.50 per share), for ten consecutive trading days on its principal stock exchange that the common shares trade. The convertible note contains customary covenants, including covenants that limit or restrict the Company’s ability to incur liens, incur indebtedness, or make certain restricted payments. Upon the occurrence of an event of default under the convertible note, the Holder may declare all amounts outstanding to be immediately due and payable. The convertible note specifies a number of events of default (some of which are subject to applicable grace or cure periods), including, among other things, non-payment defaults, covenant defaults, cross-defaults to other materials indebtedness, bankruptcy and insolvency defaults, and material judgment defaults. As of December 31, 2017, the Company was in compliance with all covenants of the convertible note. For the years ended December 31, 2017 and 2016, interest expense, including amortization of debt costs, on the convertible note was $2.2 million and $2.1 million, respectively. Related Party Debt In December 2017, the Company entered into a $2.0 million subordinated promissory note with MF Ventures, LLC, a related party. The promissory note is subordinate to the Company’s Opus Bank Credit Agreement and FBC Holdings indebtedness and has a maturity date of the earliest of: (i) December 11, 2020; (ii) immediately after repayment in full of the Opus Bank Credit Agreement and the FBC Holdings indebtedness; or (iii) immediately after the Company’s refinancing of both the Opus Bank Credit Agreement and the FBC Holdings indebtedness. The promissory note may be prepaid at any time by the Company; including any accrued and unpaid interest and a $0.3 million prepayment penalty. The promissory note bears interest at a 12.5% simple annual interest rate, payable quarterly in arrears. Interest shall be paid in kind by increasing the principal amount of the note on each quarterly interest payment date. In September 2016, the Company entered into a $2.5 million agreement with FBC Holdings. The term loan has a maturity date of January 31, 2018 and bears interest at a 20.0% simple annual interest rate, payable monthly in arrears. Monthly payments of principal on the term loan began on January 31, 2017, in 13 equal installments. The Company has the option to pre-pay the outstanding balance of the term loan, plus any accrued interest, at any time. The obligations of the Company and certain of its subsidiaries (collectively, the “Loan Parties”) under the term loan agreement and related documents will be secured by substantially all assets of the Loan Parties. At December 31, 2017, the outstanding balance of the term loan was $0.2 million. For the years ended December 31, 2017 and 2016, interest expense, including amortization of debt costs, on the term loan was $0.3 million and $0.1 million, respectively. In January 2018, the FBC Holdings term loan was paid in full per the term loan agreement. Credit Agreement In April 2016, the Company entered into a Credit Agreement with Opus Bank for a term loan in the amount of $10.0 million and a credit facility in the amount of up to $10.0 million. A portion of the proceeds were used to pay off the Company’s then outstanding credit facilities with FBC Holdings and Silicon Valley Bank. The remainder of the proceeds were used for working capital and general business requirements. On December 30, 2016, the credit facility was reduced to $8.2 million. The obligations under the term loan and credit facility are secured by substantially all assets of the Company other than the stock of its subsidiaries organized outside of the U.S. and Canada that are pledged to secure the Company’s obligations under the Company’s convertible note. At December 31, 2017 and 2016, the interest rate on the term loan and credit facility was 8.25% and 6.5%, respectively. In September 2017, the Company and Opus Bank entered into an Amendment Number Seven to Credit Agreement, Waiver and Reaffirmation (“Amendment Number Seven”). Under the terms of Amendment Number Seven; (a) the maturity date for the revolving and term loan credit facilities were amended to the earliest of (i) the maturity of the convertible note held by FBC Holdings, (ii) March 31, 2018; or (iii) such earlier date upon which the obligations may be accelerated in accordance with terms of the Credit Agreement, and (b) in the event of a failure by the Company to comply with certain covenants and milestones set forth in Amendment Number Seven, all amounts under the Opus Credit Agreement may be accelerated and become immediately payable. In March 2017, the Company and Opus Bank entered into an Amendment Number Two to Credit Agreement, Amendment Number One to Amendment Number 1, Waiver and Reaffirmation (the “Second Amendment”). As a condition of the Second Amendment, the Company issued to Opus Bank (i) a warrant, exercisable for 15,957 shares at an exercise price of $0.25 per common share as the debt was not repaid by April 17, 2017 and (ii) a warrant, exercisable for 35,242 shares at an exercise price of $0.25 per common share as the debt was not repaid by May 31, 2017. In December 2016, as a condition of the extension of credit to the Company under the Credit Agreement, the Company issued to Opus Bank a warrant exercisable for 34,483 shares at an exercise price of $0.25 per common share. The December 2016 warrant replaced the warrant that was previously issued in April 2016. The term loan and credit facility contain customary covenants, including covenants that limit or restrict the Company’s ability to incur liens, incur indebtedness, or make certain restricted payments. Upon the occurrence of an event of default under the term loan, the holder may declare all amounts outstanding to be immediately due and payable. The term loan and credit facility specify a number of events of default (some of which are subject to applicable grace or cure periods), including, among other things, non-payment defaults, covenant defaults, cross-defaults to other materials indebtedness, bankruptcy and insolvency defaults, and material judgment defaults. As of December 31, 2017, the Company was in compliance with all covenants of the term loan and credit facility. At December 31, 2017, the outstanding balances of the term loan and credit facility were $10.0 million and $8.2 million, respectively. For the years ended December 31, 2017 and 2016, interest expense, including amortization of debt costs, on the Opus facilities was $3.4 million and $1.8 million. Terminated Related Party Credit Facility In December 2014, the Company entered into a revolving credit agreement with FBC Holdings for a revolving credit facility of $5.0 million. In July 2015, the credit facility was amended to extend the scheduled maturity date to May 2016 with an automatic extension to November 2016, and the aggregate borrowing amount was increased to $10.0 million. In April 2016, the credit facility was terminated upon repayment of the outstanding balance. For the years ended December 31, 2017 and 2016, interest expense for the credit facility was none and $0.9 million, respectively, which included $0.7 million of amortization of issuance costs in the year ended 2016.

Fair Value Disclosures [Abstract]

Fair Value Disclosures [Text Block]

Fair Value Measurements

The authoritative guidance for fair value measurements establishes a three tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions.

Assets and Liabilities that are Measured at Fair Value on a Recurring Basis

Our financial instruments include cash equivalents, accounts receivable, prepaid expenses, accounts payable, accrued expenses, credit facility, debt and related party debt. Fair value estimates of these instruments are made at a specific point in time, based on relevant market information. These estimates may be subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. The carrying amount of cash equivalents, accounts receivable, prepaid expenses, accounts payable and accrued expenses are generally considered to be representative of their respective fair values because of the short-term nature of those instruments. The carrying amount of the credit facility borrowings approximate their fair value as the interest rate of the credit facility is substantially comparable to rates offered for similar debt instruments. The carrying value of debt and related party debt approximates its fair value as the borrowing rates are substantially comparable to rates available for loans with similar terms.

The following table provides information by level for liabilities that are measured at fair value using significant unobservable inputs (Level 3) (in thousands):



Warrant liability as of January 1, 2016	$	1,447
Change in fair value of warrants	(1,248		)
Reclassification to equity	1
Warrant liability as of December 31, 2016	200
Additions to warrant liability	4,677
Change in fair value of warrants	(2,249		)
Reclassification to equity	(959		)
Warrant liability as of December 31, 2017	$	1,669

The Company determined the estimated fair value of the warrant liability using a Black-Scholes model using similar assumptions as disclosed in Note 9 - Equity Incentive Plan.

Assets and Liabilities that are Measured at Fair Value on a Nonrecurring Basis

The Company's non-financial assets such as goodwill, intangible assets and property and equipment are recorded at fair value when an impairment is recognized or at the time acquired in a business combination. As discussed in Note 5 - Intangible Assets and Goodwill, at December 31, 2017, the Company recorded impairment charges associated with acquired intangible assets, and reduced the carrying amount of such assets subject to the impairment to their estimated fair value. At December 31, 2016, the Company recorded impairment charges associated with goodwill and acquired intangible assets, and reduced the carrying amount of such assets subject to the impairment to their estimated fair value.

- Definition

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.

Equity Incentive Plans

In 2017, the shareholders approved the amendment of our 2015 Performance Incentive Plan (“2015 Plan”) which increased the 2015 Plan by 1.7 million shares. The 2015 Plan, as amended, authorizes the board of directors to grant stock and options awards of up to 2.1 million common shares to directors, employees and consultants. As of December 31, 2017, the Company had approximately 770,000 share-based awards available for future grant.

In 2017, the shareholders approved the amendment of our Employee Stock Purchase Plan (“ESPP”) which increased the ESPP by 220,000 shares. The ESPP authorizes the purchase of up to 300,000 common shares by employees under the plan. As of December 31, 2017 and 2016, there were no offering periods available to employees.

Stock Options

The fair value of each option is estimated on the date of grant using the Black-Scholes option pricing model, which uses the weighted-average assumptions noted in the following table:



	Year Ended December 31,
	2017		2016
Expected volatility	120.0	%	93.0	%
Risk-free interest rate	2.1	%	1.5	%
Dividend yield	—		—
Expected term (in years)	4.7		4.7

The expected volatility was based on the Company’s historical share price. The risk-free interest rate is determined based upon a constant maturity U.S. Treasury security with a contractual life approximating the expected term of the option. The expected term of options granted is estimated based on a number of factors, including but not limited to the vesting term of the award, historical employee exercise behavior, the expected volatility of the Company’s common shares and an employee’s average length of service.

Options typically vest over a three-year period from the original grant date. The exercise price of each award is based on the market price of the Company’s common shares at the date of grant. Option awards can be granted for a maximum term of up to ten years. Option activity is summarized below (shares and aggregate intrinsic value in thousands):



	Shares		Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Term (years)	Aggregate Intrinsic Value
Options outstanding at January 1, 2016	149		$	60.75

Income Taxes

Income Tax Disclosure [Abstract]

Income Tax Disclosure [Text Block]

Income Taxes

On December 22, 2017, tax legislation referred to as the Tax Cuts and Jobs Act (the “Tax Act”) was enacted. The Tax Act reduced the U.S. corporate income tax rate from 35% to 21%, effective January 1, 2018. The Company re-measured its deferred tax assets and liabilities as of December 31, 2017, applying the reduced corporate income tax rate and recorded a provisional decrease to the deferred tax assets and liabilities of $16.7 million, with a corresponding adjustment to the valuation allowance.

Due to the complexity of the Tax Act, the Company has not finalized the accounting for the effects of the Tax Legislation, including the provisional amounts recorded related to the transition tax, re-measurement of the deferred taxes and the change to the valuation allowance. The impact of the Tax Legislation may differ from the Company’s estimate, during the one-year measurement period due to, among other things, further refinement of the Company's calculation, changes in interpretations and assumptions the Company has made, and guidance that may be issued and actions the Company may take as a result of the Tax Legislation.

The Tax Act taxes certain unrepatriated earnings and profits (“E&P”) of the Company’s foreign subsidiaries. In order to determine the Transition Tax, the Company must determine, along with other information, the amount of its accumulated post 1986 E&P for its foreign subsidiaries, as well as the non U.S. income tax paid by those subsidiaries on such E&P. The Company recorded a provisional amount of U.S. taxable income of $3.5 million, which did not result in additional tax expense due to the Company’s net operating losses. The Company continues to evaluate information which may adjust the computed Transition Tax. Since the Company has significant net operating losses, any change to this provisional amount would not have an impact on the Company’s financial position or results of operations.

The Company is subject to taxation in Canada and also in certain foreign tax jurisdictions. The Company's tax returns for calendar year 2012 and forward are subject to examination by the Canadian tax authorities. The Company's tax returns for fiscal year 2006 and forward are subject to examination by the U.S. federal and state tax authorities.

The Company recognizes the impact of an uncertain income tax position on its income tax return at the largest amount that is “more likely than not” to be sustained upon audit by the relevant taxing authority. An uncertain tax position will not be recognized if it has less than a 50% likelihood of being sustained.

The following is a summary of the changes in the amount of unrecognized tax benefits (in thousands):



	December 31,
	2017		2016
Unrecognized tax benefits, beginning of period	$	406	$	673
Decrease related to prior periods	—		(267		)
Unrecognized tax benefits, end of period	$	406	$	406

At December 31, 2017, there was $0.4 million of unrecognized tax benefits presented as a reduction of the related deferred tax asset for which there is full valuation allowance, and the entire amount of the unrecognized tax benefits at December 31, 2017 will affect the effective tax rate if recognized. However, the portion that would be recognized as an increase to deferred tax assets may result in a corresponding increase in the valuation allowance at the time of recognition resulting in no net effect to the effective tax rate, depending upon the Company’s assessment of the likelihood of realization of the tax benefits at the time they are recognized.

The Company believes it is reasonably possible that, within the next 12 months, the amount of unrecognized tax benefits may remain unchanged. The Company recognizes interest and penalties related to unrecognized tax benefits in its provision for income taxes. The Company had no material accrual for interest and penalties on its consolidated balance sheets at December 31, 2017 and 2016, and recognized no interest and/or penalties in the consolidated statements of operations for the years ended December 31, 2017 and 2016.

Deferred income taxes reflect the net effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Significant components of the Company’s deferred tax assets and liabilities are shown below. A valuation allowance has been recorded, as realization of such assets is uncertain. Deferred income taxes are comprised as follows (in thousands):



	December 31,
	2017			2016
Deferred tax assets:
Net operating loss carryforward	$	39,713		$	48,138
Intangible assets	1,989			2,791
Tax credits	2,329			2,133
Inventory	1,112			1,906
Share-based compensation	475			920
Warranty and extended warranty	289			550
Other	2,107			2,708
Deferred tax assets, gross	48,014			59,146
Valuation allowance for deferred tax assets	(46,959		)	(59,039		)
Deferred tax assets, net of valuation allowance	1,055			107
Deferred tax liabilities:
Intangible assets	(1,970		)	(3,063		)
Property and equipment	(172		)	(144		)
Deferred tax liabilities	(2,142		)	(3,207		)
Net deferred tax assets (liabilities)	$	(1,087	)	$	(3,100	)

The Company has assessed whether its valuation allowance analysis for deferred tax assets was affected by various aspects of the Tax Act (e.g., deemed repatriation of deferred foreign income, future tax on global intangible low-taxed income (“GILTI”), and new categories of foreign tax credits). Since the Company has recorded provisional amounts related to certain portions of the Tax Act, any corresponding determination of the need for or change in a valuation allowance is also provisional. The Company reduced its valuation allowance by $1.0 million as a result of the Tax Act and its effects on the realizability of its deferred tax assets.

At December 31, 2017, the Company had Canadian net operating loss carryforwards of $28.9 million. These carryforwards will begin expiring in 2031, unless previously utilized. At December 31, 2017, the Company had U.S. federal and state net operating loss carryforwards of $120.4 million and $79.2 million, respectively. The remaining federal net operating loss will begin expiring in 2023, unless previously utilized. State net operating loss carryforwards generally begin expiring in 2018, unless previously utilized.

The Company’s ability to use its U.S. federal and state net operating loss and research and development credit carryforwards may be substantially limited due to ownership change limitations that may have occurred or that could occur in the future, as required by Section 382 of the Internal Revenue Code of 1986, as amended, as well as similar state provisions. The Company has completed a study through December 31, 2014, to assess whether an ownership change has occurred or whether there have been multiple ownership changes since the Company became a “loss corporation” under the definition of Section 382. Due to the existence of the valuation allowance, it is not expected that any possible limitation will have an impact on the results of operations or financial position of the Company.

At December 31, 2017, the Company had California research and development tax credit carryforwards totaling $2.9 million. The California research credit may be carried forward indefinitely. The Company has federal alternative minimum tax credit carryforwards totaling $0.2 million which will be refundable through 2021 due to tax reform.

Litigation

The Company is, from time to time, subject to claims and suits arising in the ordinary course of business. In the opinion of management, the ultimate resolution of such pending proceedings will not have a material effect on the Company’s results of operations, financial position or cash flows.

Patent Litigation Funding Agreement

In December 2010, Overland entered into a litigation funding agreement (the “Funding Agreement”) with Special Situations Fund III QP, L.P., Special Situations Private Equity Fund, L.P., Special Situations Technology Fund, L.P., and Special Situations Technology Fund II, L.P. (collectively, the “Special Situations Funds”) pursuant to which the Special Situations Funds agreed to fund certain patent litigation brought by Overland. In May 2014, the Special Situations Funds filed a complaint against Overland in the Supreme Court for New York County, alleging breach of the Funding Agreement. The Special Situations Funds allege that Overland’s January 2014 acquisition of Tandberg Data entitled the Special Situation Funds to a $6.0 million payment under the Funding Agreement, and therefore Overland’s refusal to make the payment constitutes a breach of the Funding Agreement by Overland. In November 2014, the Special Situations Funds amended their complaint to allege that Overland breached the Funding Agreement’s implied covenant of good faith and fair dealing by settling the patent litigation with BDT in bad faith to avoid a payment obligation under the Funding Agreement. The Special Situations Funds are seeking $6.0 million in contractual damages as well as costs and fees. On October 10, 2017, the Court entered an order granting Overland’s motion for summary judgment and dismissing the Special Situations Funds’ complaint in its entirety with prejudice. The Special Situations Funds have filed a notice of appeal.

Patent Infringement

In May 2013, Safe Storage LLC (“Safe Storage”), a Delaware limited liability company, filed a complaint against Overland in the U.S. District Court for the District of Delaware alleging infringement of U.S. Patent No. 6,978,346 by our products. In February 2017, Overland and Safe Storage entered into a settlement agreement, pursuant to which the claim was dismissed.

Other

In January 2018, Mr. Vito Lupis filed a statement of claim in the Ontario Court of Justice alleging, among other things, breach of contracts, deceit and negligence against Mr. Giovanni J. Morelli, a former officer of the Company, and vicarious liability against the Company, in connection with stock purchase agreements and other related agreements that would have been entered into between Mr. Lupis and the Company in 2012. The Company believes the allegations are without merit and plans to vigorously defend itself against the allegations.

In April 2015, we filed a proof of claim in connection with bankruptcy proceedings of V3 Systems, Inc. (“V3”) based on breaches by V3 of the Asset Purchase Agreement entered into between V3 and the Company dated February 11, 2014 (the “APA”). On October 6, 2015, UD Dissolution Liquidating Trust (“UD Trust”), the apparent successor to V3, filed a complaint against us and certain of our current and former directors in the U.S. Bankruptcy Court for the District of Utah Central Division objecting to our proof of claim and asserting claims for affirmative relief against us and our directors. This complaint alleges, among other things, that Sphere breached the APA and engaged in certain other actions and/or omissions that caused V3 to be unable to timely sell the Sphere common shares received by V3 pursuant to the APA. The plaintiff seeks, among other things, monetary damages for the loss of the potential earn-out consideration, the value of the common shares held back by us pursuant to the APA and costs and fees. We believe the lawsuit to be without merit and intend to vigorously defend against the action.

On December 23, 2015, we filed a motion seeking to dismiss the majority of the claims asserted by the UD Trust. On January 13, 2016, we filed a counterclaim against the UD Trust in which we allege that V3 breached numerous provisions of the APA. On July 22, 2016, we filed a motion seeking to transfer venue of this action to the United States District Court for the District of Delaware. The Bankruptcy Court granted our motion to transfer venue on August 30, 2016, and the case was formally transferred to the Delaware Court on October 11, 2016. There is currently no hearing set on our motion to dismiss.

Subsequent Events [Abstract]
Subsequent Events [Text Block]	Subsequent Events Warrant Exchange Agreement On March 16, 2018, the Company entered into warrant exchange agreements, in a privately negotiated exchange under Section 4(a)(2) of the Securities Act of 1933, as amended, pursuant to which the Company issued 1,430,998 common shares in exchange for the surrender and cancellation of the Company’s outstanding March 24, 2017 warrants (the “Exchange”). Immediately after the Exchange, the previously issued warrants became null and void. MF Ventures, LLC, participated in the Exchange by acquiring 299,999 common shares in exchange for a warrant to purchase 272,727 common shares. Related Party Share Purchase Agreement On February 20, 2018, the Company, Overland, and Silicon Valley Technology Partners LLC, a Delaware limited liability company established and controlled by Eric Kelly, the Company’s Chief Executive Officer and Chairman of the Board of Directors (the “Purchaser”) entered into a share purchase agreement (the “Purchase Agreement”), pursuant to which, among other things, and subject to certain closing conditions, the Company will sell to Purchaser all of the issued and outstanding shares of capital stock of Overland for $45.0 million (the “Purchase Price”), subject to a working capital adjustment (the “Share Purchase”).

Significant Accounting Policies (Policies)	12 Months Ended
Significant Accounting Policies (Policies)	Dec. 31, 2017
Accounting Policies [Abstract]
Consolidation, Policy [Policy Text Block]	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.
Use of Estimates, Policy [Policy Text Block]	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 impairment assessments of goodwill, other indefinite-lived intangible assets and long-lived assets; deferred revenue; allowance for doubtful receivables; inventory valuation; warranty provisions; deferred income taxes; and litigation claims. Actual results could differ from these estimates.
Foreign Currency Transactions and Translations Policy [Policy Text Block]	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.
Cash and Cash Equivalents, Policy [Policy Text Block]	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.
Trade and Other Accounts Receivable, Policy [Policy Text Block]	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.
Inventory, Policy [Policy Text Block]	Inventories Inventories are stated at the lower of cost and net realizable value using the first-in-first-out method. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. 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 net realizable value.
Property, Plant and Equipment, Policy [Policy Text Block]	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.
Goodwill and Intangible Assets, Policy [Policy Text Block]	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 six to 25 years for channel partner relationships, three to nine years for developed technology, three to eight years for capitalized development costs, and two 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 or Disposal of Long-Lived Assets, Including Intangible Assets, Policy [Policy Text Block]	Impairment of Goodwill, Intangible Assets and Long-Lived Assets Goodwill and intangible 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. 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. Long-lived assets 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.
Revenue Recognition, Policy [Policy Text Block]	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. Depending on delivery terms, title and risk of loss transfer to the customer when the product leaves the Company’s dock, or 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. In limited circumstances where a customer is unable to accept shipment and requests products be delivered to, and stored on, the Company’s premises, revenue is recognized when: (i) the customer has accepted risk of loss and acknowledged passage of title to the goods (ii) the customer has made a fixed commitment to purchase the products, (iii) the customer has requested delayed delivery and storage of the products, (iv) there is an agreed schedule for shipment of products to the customer within a reasonable period of time, (v) the Company has no specific performance obligation such that the earnings process for the products, as a unit of accounting, is not complete, (vi) the goods are segregated from the inventory and not available to fill other orders, (vii) the product is complete, ready for shipment and accepted by the customer, and (viii) all other criteria above for revenue recognition have been met. 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 determines 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.
Standard Product Warranty, Policy [Policy Text Block]	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.
Extended Product Warranty, Policy [Policy Text Block]	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 Cost, Policy [Policy Text Block]	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, Policy [Policy Text Block]	Advertising Costs Advertising costs are expensed as incurred.
Research and Development Expense, Policy [Policy Text Block]	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.
Segment Reporting, Policy [Policy Text Block]	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 Tax, Policy [Policy Text Block]	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 Income, Policy [Policy Text Block]	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 Risk, Credit Risk, Policy [Policy Text Block]	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.
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	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. Forfeitures are recognized in share-based compensation expense as they occur. 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.
New Accounting Pronouncements, Policy [Policy Text Block]	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.

- Definition

Tabular disclosure of warrants or rights issued. Warrants and rights outstanding are derivative securities that give the holder the right to purchase securities (usually equity) from the issuer at a specific price within a certain time frame. Warrants are often included in a new debt issue to entice investors by a higher return potential. The main difference between warrants and call options is that warrants are issued and guaranteed by the company, whereas options are exchange instruments and are not issued by the company. Also, the lifetime of a warrant is often measured in years, while the lifetime of a typical option is measured in months. Disclose the title of issue of securities called for by warrants and rights outstanding, the aggregate amount of securities called for by warrants and rights outstanding, the date from which the warrants or rights are exercisable, and the price at which the warrant or right is exercisable.

Assumption of Warrants

272,727

[1]	If the Company or any subsidiary thereof, at any time while this warrant is outstanding, enters into a Variable Rate Transaction (“VRT”) (as defined in the purchase agreement) and the issue price, conversion price or exercise price per share applicable thereto is less than the warrant exercise price then in effect, the exercise price shall be reduced to equal the VRT price.
[2]	These warrants were subject to certain anti-dilution adjustments. In August 2017, the Company issued additional common shares, which triggered a price adjustment for these warrants from $7.50 to $5.00 and the issuance of an additional warrants to purchase 433,638 common shares. While these warrants are outstanding, if the Company enters into a Fundamental Transaction, defined as a merger, consolidation or similar transaction, the Company or any successor entity will, at the option of each holder, exercisable at any time within 90 days after the consummation of the Fundamental Transaction, purchase the warrant from the holder exercising such option by paying to the holder an amount of cash equal to the Black-Scholes Value of the remaining unexercised portion of such holder’s warrant on the date of the consummation of the Fundamental Transaction. On March 16, 2018, the Company entered into warrant exchange agreements pursuant to which the Company issued 1,430,998 common shares in exchange for the surrender and cancellation of the Company’s outstanding March 24, 2017 warrants (the “Exchange”). Immediately after the Exchange, the previously issued warrants became null and void. MF Ventures, LLC, participated in the Exchange by acquiring 299,999 common shares in exchange for a warrant to purchase 272,727 common shares.
[3]	Includes 624,727 of warrants to purchase common shares, in the aggregate, outstanding to related parties at December 31, 2017.
