The Rainmaker Note is secured as a registered lien under the Uniform Commercial Code and the Personal Property Security Act (Ontario) against the assets of Rainmaker and bears interest at the rate of 10% per annum. In September 2023, the Company and Rainmaker entered into Amendment No. 1 to the Rainmaker Note and the due date was extended to March 14, 2024, at which time all principal and accrued interest is due and payable. The Company has the right, at any time, to convert all or any portion of the then outstanding and unpaid Rainmaker Note and interest into at the conversion price as defined in the Rainmaker Note. On January 1, 2023, as a result of adopting ASU 2016-13, the Company recorded an allowance for credit losses of $3.8 million and reversed accrued interest of $0.1 million. All amounts related to the Rainmaker Note have been fully reserved. As of December 31, 2023 and 2022, the Rainmaker Note balance, including accrued interest, was nil and $3.8 million, respectively.

The Gryphon Note, pursuant to which the Company loaned in the aggregate to Gryphon $12.5 million, had a payment schedule whereby the principal and accrued interest shall be forgiven upon the termination of the Merger Agreement. The Gryphon Note was unsecured and bore interest at the rate of 9.5% per annum. On April 4, 2022, the Merger Agreement was terminated and $13.1 million, including interest, was forgiven and written off to other expense. As of both December 31, 2023 and 2022, the outstanding Gryphon Note balance, including accrued interest, was nil.

Investments, All Other Investments [Abstract]
Investment	Investments Special Purpose Acquisition Company In April 2021, the Company sponsored a special purpose acquisition company (“SPAC”), Minority Equality Opportunities Acquisition Inc. (“MEOA”), through our wholly owned subsidiary, Minority Equality Opportunities Acquisition Sponsor, LLC (“SPAC Sponsor”). MEOA’s purpose is to focus initially on transactions with companies that are minority owned businesses. On July 3, 2023, MEOA announced that it did not complete an initial business combination on or prior to June 30, 2023, the deadline by which it must have completed an initial business combination. As of the close of business on July 3, 2023, MEOA’s redeemable public shares were deemed cancelled and represented only the right to receive the redemption amount. MEOA instructed Continental Stock Transfer & Trust Company, the trustee of the trust account, to liquidate the redeemable securities held in the trust account. The redemption of MEOA’s redeemable public shares for $10.4 million was completed in the third quarter of 2023. The Company received no proceeds from the trust account. On November 30, 2022, after giving effect to the redemption of redeemable public shares of MEOA, the Company’s subsidiary owned a controlling interest of MEOA and it was consolidated. As of December 31, 2022, the Company held 3,162,500 shares of MEOA’s Class B common stock. The SPAC Sponsor agreed to waive its redemption rights with respect to its outstanding Class B common stock issued prior to MEOA’s initial public offering. There were no redemption rights or liquidating distributions with respect to MEOA’s warrants, which expired worthless. On December 19, 2023, the Company’s 3,162,500 shares of MEOA’s Class B common stock were cancelled, eliminating the Company’s ownership of MEOA, and the Company recognized a $6.1 million gain related to the deconsolidation of MEOA. Filecoiner Common Stock In October 2021, the Company purchased 1,500,000 shares of common stock of Filecoiner, a private corporation, at a price equal to $4.00 per share and was recorded at cost of $6.0 million. During the year ended December 31, 2022, the Company recognized an impairment for the common stock of Filecoiner held and recorded an impairment expense of $6.0 million. Filecoiner Preferred Stock In October 2021, the Company received 8,000 shares of Series B preferred stock of Filecoiner (“Filecoiner Series B Preferred Stock”) for consideration for the sale of its SnapServer® product line to Filecoiner. The preferred shares have a liquidation preference of $1,000 per share, do not accrue dividends nor have voting rights. Filecoiner will use 1.5% of its annual gross revenue to redeem any outstanding shares of Filecoiner Series B Preferred Stock. This amount will be paid to the holder of the Filecoiner Series B Preferred Stock within 15 days of the completion of Filecoiner's annual December 31 audited financial statements. During any 12-calendar month period, 25% of the shares of Series B Preferred Stock shall be convertible at the option of the holder thereof at any time into a number of shares of common stock determined by dividing (i) the original issue price by (ii) the conversion price then in effect. The initial conversion price for the Series B Preferred Stock is equal to $8.00 per share. The conversion price from time to time in effect is subject to adjustment as hereinafter defined in the Filecoiner acquisition agreement. The fair value of the Filecoiner Series B Preferred Stock was estimated using a Monte Carlo simulation with the following inputs: discount rate of 40%, risk-free rate of 1.05%, cost of debt of 7.48%, together with a capital option pricing model using the following inputs: volatility of 146% and risk-free rate of 1.05%. As of December 31, 2021, the fair value of the Filecoiner Series B Preferred Stock held by the Company was $6.4 million. During the year ended December 31, 2022, the Company recognized an impairment for the preferred stock of Filecoiner held and recorded an impairment expense of $6.4 million. Silicon Valley Technology Partners Preferred Shares In November 2018, in connection with the divestiture of Overland, the Company received 1,879,699 SVTP Preferred Shares with a fair value of $2.1 million. The Company concluded it does not have a significant influence over the investee. During the year ended December 31, 2022, the Company recognized an impairment for the SVTP Preferred Shares held and recorded an impairment expense of $2.1 million.

Earnings Per Share [Abstract]

Earnings Per Share [Text Block]

Net Loss per Share

Basic net loss per share is computed by dividing net loss applicable to common shareholders by the weighted-average number of common shares outstanding during the period. Preferred shares, common share outstanding purchase warrants, and outstanding options and RSUs are considered common stock equivalents and are only included in the calculation of diluted earnings per common share when net income is reported and their effect is dilutive. For all periods presented, there is no difference in the number of shares used to calculate basic and diluted shares outstanding due to the Company’s net loss position.

Anti-dilutive common share equivalents excluded from the computation of diluted net loss per share were as follows:


	December 31,
	2023	2022
Preferred shares	6,216,422	8,571,429
Common share purchase warrants	5,842,354	2,826,220

Summary of 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. Subsidiaries in which controlling interests are maintained are consolidated. 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 disclosure of contingent assets and liabilities at the date of the financial statements and reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates.

Reclassifications

Certain prior period amounts have been reclassified for consistency with the current period presentation. The reclassifications did not have a material impact on the Company's consolidated financial statements and related disclosures.

The financial statements of the Company’s foreign subsidiary, for which the functional currency is the local currency, is 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 accumulated other comprehensive income (loss) within shareholders’ equity. Gains or losses from foreign currency transactions are recognized in the consolidated statements of operations. Such transactions resulted in a minimal gain and $46,000 loss for the years ended December 31, 2023 and 2022, respectively.

Cash and 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 Company maintains cash and cash equivalent balances with financial institutions that exceed federally insured limits. The Company has not experienced any losses related to these balances and believes credit risk to be minimal.

Restricted Cash

Restricted cash is cash held in a separate bank account with restrictions on withdrawal. The Company’s restricted cash was classified as current and pledged as collateral for a standby letter of credit for the bonding purpose necessary for the Company to receive mining machines and was released in 2023.

Funds held in trust account were restricted and invested in U.S. government treasury money market funds. During the year ended December 31, 2023, the proceeds were released from the trust account to MEOA for the redemption of its redeemable public shares as MEOA was unable to complete the required business combination.

Accounts Receivable

Accounts receivable is recorded at the invoiced amount and is non-interest bearing. The Company estimates its 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, the Company analyzes 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. The Company reviews the allowance for doubtful accounts on a quarterly basis and records adjustments as considered necessary. Customer accounts are written-off against the allowance for doubtful accounts when an account is considered uncollectable. At December 31, 2023 and 2022, allowance for doubtful accounts of nil and $3,200, respectively, was recorded.

Digital Assets

The Company accounts for its digital assets, Bitcoin, as indefinite-lived intangible assets. The digital assets are recorded at cost less impairment. An impairment analysis is performed daily to determine if the fair value of Bitcoin is lower than the Company’s carrying value for Bitcoin until the Company’s Bitcoin is disposed of or until the end of the reporting period, whichever comes first. The fair value of digital assets is determined on a nonrecurring basis based on the lowest intraday quoted price as reported in the Company’s principal market. If the carrying value of the digital asset exceeds the fair value an impairment loss has occurred with respect to those digital assets in the amount equal to the difference between their carrying values and the fair value determined.

Impairment losses are recognized in operating costs and expenses in the consolidated statements of operations in the period in which the impairment is identified. The impaired digital assets are written down to their fair value at the time of impairment and this new cost basis will not be adjusted upward for any subsequent increase in fair value. Gains are not recorded until realized upon sale or disposition.

Digital assets awarded to the Company through its mining activities are included within operating activities on the accompanying consolidated statements of cash flows. The disposal of digital assets are included within operating activities in the accompanying consolidated statements of cash flows and any realized gains or losses from such sales are included in operating costs and expenses in the consolidated statements of operations. The Company accounts for its gains or losses in accordance with the first in first out (FIFO) method of accounting.

The following table presents the activities of the digital assets (in thousands):


Balance at January 1, 2022	$	—
Addition of digital assets	3,443
Bitcoin issued for services	(600)
Impairment loss	(1,148)
Balance at December 31, 2022	1,695
Addition of Bitcoin	19,730
Bitcoin sold for cash	(18,195)
Bitcoin issued for services	(1,562)
Impairment loss	(682)
Balance at December 31, 2023	$	986

Allowance for Credit Losses

The Company’s assessment of its allowance for credit losses requires it to incorporate considerations of historical information, current conditions and reasonable and supportable forecasts. The Company manages credit risk through review of available public company information. For the Company’s note receivable, as of December 31, 2023, the Company has recorded an allowance for credit losses and elected to write off accrued interest receivables by reversing interest income.

Investments

The Company holds investments in equity securities of public and nonpublic companies for business and strategic purposes. Nonpublic equity securities that do not have a readily determinable fair value are carried at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. The Company reviews its investments on a regular basis to determine if the investments are impaired. For purposes of this assessment, the Company considers the investee’s cash position, earnings and revenue outlook, liquidity and management ownership, among other factors, in its review. If management’s assessment indicates that an impairment exists, the Company estimates the fair value of the equity investment and recognizes in current earnings an impairment loss that is equal to the difference between the fair value of the equity investment and its carrying amount.

Leases

The Company enters into operating leases primarily for real estate. The Company determines if an arrangement contains a lease at inception. Right of use (“ROU”) assets and liabilities resulting from operating leases are included in property and equipment, other current liabilities and other non-current liabilities on our consolidated balance sheets. Operating lease ROU assets and liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. As the leases typically do not provide an implicit rate, the Company uses the incremental borrowing rate based on the information available at commencement date in determining the discount rate to calculate the present value of future payments. The operating lease ROU asset may also include any lease payments made and exclude lease incentives and initial direct costs incurred. The Company’s leases do not include options to extend the lease. Short-term leases with an initial term of 12 months or less are not recorded on the balance sheet. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term. On December 28, 2023, the Company sold its Service and Product segment and no longer has any operating leases or ROU assets and liabilities as of December 31, 2023.

Property and Equipment

Property and equipment primarily consists of mining equipment and is stated at cost, including purchase price and all shipping and custom fees, and depreciated using the straight-line method over the estimated useful lives of the assets, generally five years.

The Company reviews the carrying amounts of property and equipment when events or changes in circumstances indicate the assets may not be recoverable. If any such indication exists, the fair value of the asset is estimated in order to determine the extent of the impairment loss, if any.

Intangible Assets

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 five years to 15 years for supplier agreements, six years for channel partner relationships, and seven years for customer relationships as this method most closely reflects the pattern in which the economic benefits of the assets will be consumed.

The Company has purchased carbon credits. As it intends to use these carbon credits, the assets have been classified as intangible assets. When the carbon credit is used, it is expensed as an operating expense.

Impairment of Intangible Assets

The Company performs regular reviews of intangible assets to determine if any event has occurred that may indicate that intangible assets with finite useful lives and other long-lived assets are potentially impaired. 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.

Warrant Liabilities

Warrant liabilities are for a common share purchase warrant issued in connection with previously outstanding convertible debt, and warrants for shares of MEOA’s common stock that are not indexed to its own stock. Warrants are presented as liabilities at fair value on the consolidated balance sheets. The warrants are subject to remeasurement at each balance sheet date and any change in fair value is recognized in interest income and other expense, net, in the consolidated statements of operations.

Redeemable Non-controlling Interest

Redeemable non-controlling interest is interest in a subsidiary of the Company that are redeemable outside of the Company’s control either for cash or other assets. This interest is classified as temporary equity and measured at the estimated redemption value at the end of each reporting period. The resulting increases or decreases in the estimated redemption amount are effected by corresponding charges to accumulated deficit. At December 31, 2022, redeemable non-controlling interest recorded within the Company’s consolidated balance sheet relates to its subsidiary, MEOA. At December 31, 2023, redeemable non-controlling interest was no longer subject to consolidation with the Company.

Revenue Recognition

The Company accounts for revenue pursuant to ASU 2014-09, Revenue from Contracts with Customers and all the related amendments (“Topic 606”). 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, and contract consideration will be recognized on a “sell-in basis” or when control of the purchased goods or services transfer to the distributor.

The Company is engaged with digital asset mining pool operators to provide computing power to the mining pools. In exchange for providing computing power, the Company is entitled to Full Pay Per Share (“FPPS”), which is a fractional share of the fixed Bitcoin award the mining pool operator receives, plus a fractional share of the transaction fees attached to that blockchain less net digital asset fees due to the mining pool operator over the measurement period, as applicable. The pay-outs received are based on the expected value from the block reward plus the transaction fee reward, regardless of whether the mining pool operator successfully records a block to the blockchain.

The Company’s fractional share is based on the proportion of computing power the Company contributed to the mining pool operator to the total computing power contributed by all mining pool participants in solving the current algorithm. The contracts are terminable at any time by either party without compensation and the Company’s enforceable right to compensation only begins when the Company starts providing computing power to the mining pool operator (which occurs daily at midnight Universal Time Coordinated (“UTC”)). The contract arises at the point that the Company provides computing power to the mining pool operator, which is beginning contract day at midnight UTC (contract inception), as customer consumption is in tandem with daily earnings of delivery of the computing power. According to the customer contract, daily earnings are calculated from midnight-to-midnight UTC time, and the sub-account balance is credited one hour later at 1:00 AM UTC time.

The Company satisfies its performance obligation over time with daily settlement in Bitcoin. The Company’s performance is completed as it transfers the computing power (hashrate computations) over-time (midnight to midnight) to the customer. The Company has full control of the mining equipment utilized in the mining pool and if the Company determines it will increase or decrease the processing power of its machines and/or fleet (i.e., for repairs or when power costs are excessive) the computing power provided to the customer will be adjusted.

The transaction consideration the Company receives is noncash consideration in the form of Bitcoin, which the Company measures at fair value at contract inception. The noncash consideration is variable, since the amount of block reward earned depends on the amount of computing power contributed, the amount of transaction fees awarded and operator fees over the same period. The Company does not constrain this variable consideration because it is probable that a significant reversal in the amount of revenue recognized from the contract will not occur when the uncertainty is subsequently resolved and recognizes the noncash consideration on the same day that control is transferred, which is the same day as contract inception.

Expenses associated with running the Bitcoin mining operations, such as hosting, operating supplies, utilities and monitoring services are recorded as cost of revenues.

The Company also generates revenue from: (i) solutions for standalone storage and integrated hyper-converged storage; (ii) professional services; and (iii) warranty and customer services. The Company recognizes revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services. To determine revenue recognition for contracts with customers the Company performs the following five steps: (i) identify the promised goods or services in the contract; (ii) identify the performance obligations in the contract, including whether they are distinct in the context of the contract; (iii) determine the transaction price, including the constraint on variable consideration; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the Company satisfies the performance obligations.

The majority of the Company’s product and service revenue is recognized when performance obligations under the terms of a contract with a customer are satisfied at a point in time. These contracts are generally comprised of a single performance obligation to transfer products. Accordingly, the Company recognizes revenue when change of control has been transferred to the customer, generally at the time of shipment of products. The Company sells its products both directly to customers and through distributors generally under agreements with payment terms typically less than 45 days. Revenue on direct product sales, excluding sales to distributors, 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. Product sales to distribution customers that are subject to certain rights of return, stock rotation privileges and price protections, contain a component of “variable consideration.” Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring products and is generally based upon a negotiated fixed price and is net of estimates for variable considerations.

For performance obligations related to warranty and customer services, such as extended product warranties, the Company transfers control and recognizes revenue on a time-elapsed basis. The performance obligations are satisfied as services are rendered typically on a stand-ready basis over the contract term, which is generally 12 months.

The Company also enters into revenue arrangements that may consist of multiple performance obligations of its product and service offerings such as for sales of hardware devices and extended warranty services. The Company allocates contract fees to the performance obligations on a relative stand-alone selling price basis. The Company determines the stand-alone selling price based on its normal pricing and discounting practices for the specific product and/or service when sold separately. When the Company is unable to establish the individual stand-alone price for all elements in an arrangement by reference to sold separately instances, the Company may estimate the stand-alone selling price of each performance obligation using a cost plus a margin approach, by reference to third party evidence of selling price, based on the Company’s actual historical selling prices of similar items, or based on a combination of the aforementioned methodologies; whichever management believes provides the most reliable estimate of stand-alone selling price.

Extended Warranty

Separately priced extended on-site warranties and service contracts are offered for sale to customers on all product lines. Extended warranty and service contract revenue and recognized as service revenue over the period of the service agreement. The Company will typically apply the practical expedient to agreements wherein the period between transfer of any good or service in the contract and when the customer pays for that good or service is one year or less. On December 28, 2023, the Company sold its service and product segment and no longer has any deferred revenue for extended on-site warranties and service contracts as of December 31, 2023.

Shipping and Handling

Amounts billed to customers for shipping and handling are included in revenue, and costs incurred related to shipping and handling are included in cost of product revenue.

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. Research and development expenses are charged to operating expenses as incurred when these expenditures relate to the Company’s research and development efforts and have no alternative future uses.

Segment Information

Operating segments are defined as components of an enterprise for which separate financial information is available and evaluated regularly by the chief operating decision maker, or decision-making group, in deciding the method to allocate resources and assess performance. Through the period ended December 28, 2023, the Company had two operating segments. On December 28, 2023, the Company sold its service and product segment.

Income Taxes

The Company provides 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 (Loss)

Comprehensive income (loss) and its components encompass 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, the Company performs ongoing credit evaluations of its customers and maintain allowances for potential credit losses for estimated bad debt losses.

Share-based Compensation

The Company accounts for share-based awards, and similar equity instruments, granted to employees, non-employee directors, and consultants in accordance with the authoritative guidance for share-based compensation. Share-based compensation award types may include stock options and restricted stock units (“RSUs”) and restricted stock awards (“RSAs”). Share-based compensation expense is recognized on a straight-lined basis over the requisite service period (usually the vesting period) except for options with graded vesting which is recognized pursuant to an accelerated method. Forfeitures are recognized as a reduction in share-based compensation expense as they occur.

Non-controlling Interest

The Company accounts for its non-controlling interest in accordance with the authoritative guidance for consolidation which governs the accounting for and reporting of non-controlling interests (“NCIs”) in partially owned consolidated subsidiaries and the loss of control of subsidiaries. Certain provisions of the guidance indicate, among other things, that NCIs be treated as a separate component of equity, not as a liability, that increases and decreases in the parent’s ownership interest that leave control intact be treated as equity transactions rather than as step acquisitions or dilution gains or losses, and that losses of a partially owned consolidated subsidiary be allocated to the NCI even when such allocation might result in a deficit balance. The net income (loss) attributed to the NCI is separately designated in the accompanying consolidated statements of operations. At December 31, 2023, the Company no longer owned a controlling interest in MEOA and as such the non-controlling interest was no longer subject to consolidation with the Company.

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 November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires public entities with a single reportable segment to provide all the disclosures required by this standard and all existing segment disclosures in Topic 280 on an interim and annual basis, including new requirements to disclose significant segment expenses that are regularly provided to the chief operating decision maker (“CODM”) and included within the reported measure(s) of a segment's profit or loss, the amount and composition of any other segment items, the title and position of the CODM, and how the CODM uses the reported measure(s) of a segment's profit or loss to assess performance and decide how to allocate resources. The guidance is effective for annual periods beginning after December 15, 2023, and interim periods beginning after December 15, 2024, applied retrospectively with early adoption permitted. The Company is evaluating the impact of adoption of this standard on its consolidated financial statements and disclosures.

In December 2023, the FASB issued ASU 2023-08, Intangibles - Goodwill - and Other - Crypto Assets (Subtopic 350-60): Accounting For and Disclosure of Crypto Assets, which requires that an entity measure crypto assets at fair value in the statement of financial position each reporting period and recognize changes from remeasurement in net income. The amendments also require that an entity provide enhanced disclosures for both annual and interim reporting periods to provide investors with relevant information to analyze and assess the exposure and risk of significant individual crypto asset holdings. In addition, fair value measurement aligns the accounting required for holders of crypto assets with the accounting for entities that are subject to certain industry-specific guidance and eliminates the requirement to test those assets for impairment, thereby reducing the associated cost and complexity of applying the current guidance. The guidance is effective for annual periods beginning after December 15, 2024, and interim periods beginning after December 15, 2024, applied retrospectively with early adoption permitted. The Company expects to early adopt the new standard effective January 1, 2024 and does not expect a material impact on its consolidated financial statements and disclosures.

In December 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures, which requires more detailed income tax disclosures. The guidance requires entities to disclose disaggregated information about their effective tax rate reconciliation as well as expanded information on income taxes paid by jurisdiction. The disclosure requirements will be applied on a prospective basis, with the option to apply them retrospectively. The standard is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. The Company is evaluating the disclosure requirements related to the new standard.

Recently Adopted Accounting Pronouncements

In June 2016, the FASB issued Accounting Standards Update No. 2016-13, Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”). ASU 2016-13 amends the impairment model by requiring entities to use a forward-looking approach based on expected losses to estimate credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. Entities will no longer be permitted to consider the length of time that fair value has been less than amortized cost when evaluating when credit losses should be recognized. The Company adopted ASU 2016-13 on January 1, 2023 on a modified retrospective basis which resulted in a $3.8 million increase to the opening balance of accumulated deficit, representing the cumulative allowance for credit losses for the Company’s note receivable.

In October 2021, the FASB issued Accounting Standards Update No. 2021-08, Accounting for Contract Assets and Contract Liabilities from Contracts with Customers (“ASU 2021-08”). ASU 2021-08 amends ASC 805 to require acquiring entities to apply Topic 606 to recognize and measure contract assets and contract liabilities in a business combination. The Company adopted the new standard beginning January 1, 2023, however it did not have an effect on its financial position, results of operations or cash flows.

Impairment of Intangible Assets

During the year ended December 31, 2023, a certain vendor for the Company’s carbon credits was not able to perform under terms of the agreement, which indicated that an impairment triggering event occurred for the carbon credits held for future use, and the Company determined the carrying value of the indefinite-lived intangible asset exceeded its estimated fair value. The Company compared the indicated fair value to the carrying value of its indefinite-lived asset, and as a result of the analysis, an impairment charge of $1.7 million was recorded for the carbon credits held for future use for the year ended December 31, 2023.

During the year ended December 31, 2023, adverse changes in the business climate indicated that an impairment triggering event occurred for one supplier agreement, and the Company determined the carrying value of the finite-lived intangible asset exceeded its estimated fair value. The Company compared the indicated fair value to the carrying value of its finite-lived asset, and as a result of the analysis, an impairment charge of $1.2 million was recorded for the supplier agreement for the year ended December 31, 2023.

For the year ended December 31, 2022, adverse changes in the business climate, including the decline in the price of Bitcoin and two vendor bankruptcy filings, indicated that an impairment triggering event occurred, and the Company determined the carrying value of finite-lived intangible assets exceeded its estimated fair value. In measuring fair value, the Company used a weighted income and market approach. For the income approach, the Company used discounted cash flow analysis and for the market approach, the Company used the sales price (market price) of similar assets. The Company compared the indicated fair value to the carrying value of its finite-lived assets, and as a result of the analysis, an impairment charge of $13.2 million was recorded for supplier agreements for the year ended December 31, 2022.

Hertford Asset Acquisition

On July 31, 2021, the Company entered into an agreement (the “Hertford Agreement”) with Hertford Advisors Ltd. (“Hertford”), a privately held company that provides turnkey mining solutions, to provide an exclusive right to assume all of Hertford’s rights to a number of digital asset mining hardware agreements (the “Equipment Agreements”). The Company has assumed and executed the first Equipment Agreement directly with the manufacturer, for the purchase of up to 60,000 new digital asset mining machines, with deliveries that commenced in January 2022. In exchange for the assignment of the Equipment Agreements for which the Company has the right, but not the obligation to complete, in 2021 the Company issued to Hertford common and preferred shares with an aggregate value of $53.8 million and was included in supplier agreements.

In November 2022, the Company entered into an agreement with Hertford modifying the number of outstanding preferred shares held by Hertford (the “Modified Hertford Agreement”). Pursuant to the Modified Hertford Agreement, the Company cancelled 36,000 Series H Preferred Shares, with a value of $15.9 million, without payment of any cash consideration, and reduced the value of the supplier agreement intangible asset by such amount.

Debt Disclosure [Abstract]

Debt Disclosure [Text Block]

Convertible Debt

On April 17, 2023, the Company entered into a Securities Purchase Agreement (the “LDA Purchase Agreement”) pursuant to which the Company issued to an investor, LDA Capital Limited (the “Investor”), a senior convertible promissory note having an aggregate principal amount of $1.0 million (the “LDA Note”), as amended April 25, 2023, and a common share purchase warrant (the “LDA Warrant”) to purchase up to 455,927 common shares of the Company (the “LDA Warrant Shares”). The Company received proceeds of approximately $0.8 million, which were net of fees associated with the transaction, on April 18, 2023 (the “Closing Date”). The LDA Note matures 24 months after issuance, bears interest at a rate of 7.5% per annum and is convertible into the Company's common shares (the “Conversion Shares”), at the Investor's election, at an initial conversion price equal to the greater of (i) $2.0832 per share, or (ii) 85% of the VWAPS (as defined in the LDA Note) during the trading five days prior to delivery of a conversion notice by the Investor, subject to adjustment for certain stock splits, stock combinations and dilutive share issuances.

On August 14, 2023, in accordance with the terms of the LDA Purchase Agreement prepayment option, the Company repaid the full amount of the LDA Note, including interest and fees, in the amount of $1.3 million. As a result of the repayment, the Company redeemed from the holder of the LDA Warrant 40% of the then outstanding LDA Warrant, or 182,371 LDA Warrant Shares. At December 31, 2023, the balance of the LDA Note was nil. The Company recognized a loss on debt extinguishment of $63,000 which is included in the consolidated statement of operations in interest income and other expense, net.

The LDA Warrant is exercisable at an initial exercise price of $3.29 per share and expires three years from the date of issuance or earlier if the closing of a Fundamental Transaction occurs (defined as merger or consolidation, any sale of substantially all of the Company’s assets, any tender offer or exchange offer pursuant to which common shareholders can tender or exchange their shares for other securities, cash or property, as well as any reclassification of common shares into other securities, cash or property). On the date that is six months from the date of issuance of the LDA Warrant, the exercise price will be adjusted to the lower of (i) $3.29, and (ii) a price equal to 110% of the average of the VWAPS (as defined in the LDA Warrant) of the Company's common shares over five days of trading preceding such date. Additionally, the exercise price of the LDA Warrant is subject to adjustment for certain stock splits, stock combinations and dilutive share issuances. Pursuant to the terms of the LDA Purchase Agreement, the Company will reserve for issuance 200% of the maximum aggregate number of common shares as are issuable upon repayment or conversion in full of the LDA Note and exercise in full of the LDA Warrant at any time. In October 2023, the Company adjusted the LDA Warrant exercise price from $3.29 to $1.342 pursuant to the terms in the LDA Purchase Agreement.

On December 29, 2023, the Company issued 123,806 common shares with a value of $0.4 million for a cashless exercise of 200,000 LDA Warrant Shares.

The LDA Warrant contains a contingent put option. In the event of a Fundamental Transaction, the Investor may, at the Investor’s option, require the Company to purchase the LDA Warrant for an amount of cash equal to the Black Scholes value of the remaining unexercised portion of the warrant on the date of consummation of such Fundamental Transaction. The Company has recorded the warrant as a liability and will adjust the warrant liability to fair value each reporting period until settled.

On April 17, 2023, upon issuance of the LDA Note and LDA Warrant, which are accounted for as freestanding financial instruments, the Company determined that the aggregate fair value of $2.0 million for the instruments issued exceeds the net proceeds received under the transaction. Accordingly, the excess of the fair value over the proceeds received of $1.0 million was recognized as interest expense. The initial fair value of the LDA Warrant was measured using a Monte Carlo valuation model and at December 31, 2023 using a Black Scholes valuation model with the following assumptions, respectively:


	April 17, 2023			December 31, 2023
Common share price	$	2.98		$	3.47
Expected volatility	120.0		%	120.0		%
Risk-free interest rate	3.8		%	4.2		%

Equity Incentive Plans

As of December 31, 2023, a total of 820,585 common shares are authorized for issuance with respect to awards primarily granted under the 2015 Plan. In addition, the share limit will automatically increase on the first trading day in January of each calendar year during the term of the 2015 Plan by an amount equal to the lesser of (i) 10% of the total number of common shares issued and outstanding on December 31 of the immediately preceding calendar year, or (ii) such number of common shares as may be established by the Board. The 2015 Plan authorizes the board of directors to grant stock and options awards to directors, employees and consultants. As of December 31, 2023, the Company had approximately 366,415 share-based awards available for future grant.

The Company’s Employee Stock Purchase Plan (“ESPP”) authorizes the purchase of up to 5,357 common shares by employees under the plan. As of December 31, 2023 and 2022, there were no offering periods available to employees.

The following table summarizes option activity:


	Shares Subject to Options	Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Term (years)	Aggregate Intrinsic Value (in thousands)

Exercisable — December 31, 2023	325,599	$	5.39	4.5	$	222

The weighted average grant date fair values of options granted during the years ended December 31, 2023 and 2022 were $0.58 per share and $4.92 per share, respectively. For the years ended December 31, 2023 and 2022, the intrinsic value of stock options exercised was $0.1 million and nil, respectively. Cash received from stock option exercises for the years ended December 31, 2023 and 2022 was approximately $0.6 million and nil, respectively.

The fair value of each option was estimated on the date of grant using the Black-Scholes option pricing model. 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 based on term of the award. Option awards can be granted for a maximum term of up to ten years. The assumptions used in the Black-Scholes model were as follows:


	Year Ended December 31,
	2023	2022
Expected volatility	81.8-84.0%	121.7-124.4%
Expected term (in years)	0.5	3.9
Risk-free interest rate	5.27-5.52%	2.71-3.91%

Restricted Stock Units

The following table summarizes RSU activity:


	Number of Shares	Weighted Average Grant Date Fair Value
Outstanding — January 1, 2022	8,571	$	24.22

Forfeited	(20,953)	$	6.78
Outstanding — December 31, 2023	58,929	$	9.51

The estimated fair value of RSUs was based on the market value of the Company’s common shares on the date of grant. RSUs typically vest over a period of one year to three years from the original date of grant. The total grant date fair value of RSUs vested during the years ended December 31, 2023 and 2022 was approximately $1.7 million and $7.2 million, respectively. The fair value of RSUs vested during the years ended December 31, 2023 and 2022 was approximately $0.7 million and $2.5 million, respectively.

Restricted Stock Awards

The Company granted restricted stock awards (“RSA”) to certain employees and consultants in lieu of cash payment for services performed. The estimated fair value of the RSAs was based on the market value of the Company’s common shares on the date of grant. The RSAs were fully vested on the date of grant. The fair value of the RSAs vested during the years ended December 31, 2023 and 2022 was approximately $0.2 million and nil, respectively.

The following table summarizes RSA activity:

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	Organization and Business Sphere 3D Corp. 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.” Any reference to the “Company”, “Sphere 3D”, “we”, “our”, “us”, or similar terms refers to Sphere 3D Corp. and its subsidiaries. In January 2022, the Company commenced operations of its Bitcoin mining business and is dedicated to becoming a leader in the Blockchain and Crypto Industry. The Company has established and plans to continue to grow an enterprise-scale mining operation through the procurement of mining equipment and partnering with experienced service providers. In addition, through December 28, 2023, the Company delivered data management and desktop and application virtualization solutions through hybrid cloud, cloud and on premise implementations by its global reseller network. On December 28, 2023, the Company sold its service and product segment which included HVE ConneXions and Unified ConneXions. Liquidity and Going Concern The Company has recurring losses from operations and incurred a net loss of approximately $23.3 million for the year ended December 31, 2023. Management has projected that based on our hashing rate at December 31, 2023, cash on hand may not be sufficient to allow the Company to continue operations and there is substantial doubt about the Company’s ability to continue as a going concern within 12 months from the date of issuance of the financial statements if we are unable to raise additional funding for operations. We expect our working capital needs to increase in the future as we continue to expand and enhance our operations. Our ability to raise additional funds for working capital through equity or debt financings or other sources may depend on the financial success of our then current business and successful implementation of our key strategic initiatives, financial, economic and market conditions and other factors, some of which are beyond our control. Further equity financings may have a dilutive effect on shareholders and any debt financing, if available, may require restrictions to be placed on our future financing and operating activities. We require additional capital and if we are unsuccessful in raising that capital at a reasonable cost and at the required times, or at all, we may not be able to continue our business operations in the cryptocurrency mining industry or we may be unable to advance our growth initiatives, either of which could adversely impact our business, financial condition and results of operations. Significant changes from the Company’s current forecasts, including but not limited to: (i) shortfalls from projected mining earning levels; (ii) increases in operating costs; (iii) fluctuations in the value of cryptocurrency; and (iv) 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 seek bankruptcy protection or be subject to an involuntary bankruptcy petition, any of, which would have a material adverse effect on the Company’s business, results of operations, financial position and liquidity. These factors, among others, indicate there is substantial doubt about the Company’s ability to continue as a going concern within 12 months from the date of issuance of the financial statements. 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 and do not include any adjustments that might result from the outcome of this uncertainty. Share Consolidation On June 28, 2023, the Company filed Articles of Amendment to effect a share consolidation (also known as a reverse stock split) of its issued and outstanding common shares on a one-for-seven basis. The share consolidation became effective on June 28, 2023. All share and per share amounts have been restated for all periods presented to reflect the share consolidation.

Preferred Stock [Text Block]	Preferred Shares Series H Preferred Shares On October 1, 2021, the Company filed articles of amendment to create a series of preferred shares, being, an unlimited number of Series H Preferred Shares and to provide for the rights, privileges, restrictions and conditions attaching thereto. The Series H Preferred Shares are convertible provided (and only if and to the extent) that prior shareholder approval of the issuance of all Sphere 3D common shares issuable upon conversion of the Series H Preferred Shares has been obtained in accordance with the rules of the Nasdaq Stock Market, at any time from time to time, at the option of the holder thereof, into 142.857 Sphere 3D common shares for every Series H Preferred Share. Each holder of the Series H Preferred Shares, may, subject to prior shareholder approval, convert all or any part of the Series H Preferred Shares provided that after such conversion the common shares issuable, together with all the common shares held by the shareholder in the aggregate would not exceed 9.99% of the total number of outstanding common shares of the Company. Each Series H Preferred Share has a stated value of $1,000. The Series H Preferred Shares are non-voting and do not accrue dividends. These features include, in the event of the liquidation, dissolution or winding-up of the Company, whether voluntary or involuntary, deemed liquidation or any other distribution of the assets of the Company among its shareholders for the purpose of winding-up its affairs, the Series H Preferred Shares shall entitle each of the holders thereof to receive an amount equal to the Series H subscription price per Series H Preferred Share, as defined in the agreement, to be paid before any amount is paid or any assets of the Company are distributed to the holders of its common shares. In November 2022, the Company entered into the Modified Hertford Agreement. Pursuant to the Modified Hertford Agreement, the Company cancelled 36,000 Series H Preferred Shares, with a value of $15.9 million, without payment of any cash consideration, and reduced the value of the supplier agreement intangible asset by such amount. The Modified Hertford Agreement also provides for certain resale restrictions applicable to the common shares that are issuable upon the conversion of the remaining Series H Preferred Shares during the two-year period ending on December 31, 2024, which are different from the restrictions contained in the Hertford Agreement, as well, commencing January 1, 2023 and terminating on December 31, 2023, holders of Series H Preferred Shares are permitted to (a) convert Series H Preferred Shares in an aggregate amount up to or equal to 3.0% of the aggregate number of Series H Preferred Shares outstanding on the first day of each such month and (b) sell the resulting number (and no greater number) of such converted common shares within such month. Commencing January 1, 2024 and terminating on December 31, 2024, holders of Series H Preferred Shares are permitted to (a) convert Series H Preferred Shares in an aggregate amount up to or equal to 10.0% of the aggregate number of Series H Preferred Shares outstanding on the first day of each such month and (b) sell the resulting number (and no greater number) of such converted common shares within such month. In August 2023, the Company entered into an Amended and Restated Agreement (the “Hertford Amendment”) with Hertford Advisors Ltd. and certain other parties listed in the Hertford Amendment (together, the “Hertford Group”), which amends and restates in its entirety the purchase agreement between the Company and Hertford Advisors Ltd. dated July 31, 2021, as modified by the amendment to such agreement dated November 7, 2022 (together, the “Original Hertford Agreement”). As an inducement to enter into the Hertford Amendment, the Company issued to Hertford 1,376 Series H Preferred Shares and 800,000 warrants with an aggregate fair value of $1.0 million. Pursuant to the Hertford Amendment, Hertford exchanged 14,980 Series H Preferred Shares for Series H Preferred Shares held by other persons (the “Exchanged Series H Preferred Shares”). The offer and sale of the Series H Preferred Shares and the Warrants have not been registered under the Securities Act and may not be offered or sold in the United States in the absence of an effective registration statement or exemption from the registration requirements, and in each case in compliance with applicable state securities laws. In August 2023, the Company entered into a Securities Purchase Agreement (the “Purchase Agreement”) pursuant to which the Company issued to two investors a total of 13,764 of the Company’s Series H Preferred Shares and a total of 1,966,293 common share purchase warrants (the “Warrants”), each of which entitled the holder to purchase one common share of the Company (the “Warrant Shares”). Pursuant to the terms of the Purchase Agreement, the Company received gross proceeds of $3.0 million. The Company issued a total of 1,377 Series H Preferred Shares and 196,629 warrants as a finder’s fee for the transaction with an aggregate fair value of $0.5 million. Pursuant to the terms of the Purchase Agreement, the Company will reserve for issuance the maximum aggregate number of common shares that are issuable upon exercise in full of the Warrants at any time. The Warrants issued in connection with the Hertford Amendment and the Purchase Agreement are exercisable beginning February 12, 2024 and February 23, 2024, respectively, at an initial exercise price of $2.75 per share and have a term of three years from the date of issuance. The exercise price of the Warrants are subject to adjustment for certain stock splits, stock combinations and dilutive share issuances. In accordance with the authoritative guidance for distinguishing liabilities from equity, the Company has determined that its Series H preferred shares carry certain redemption features beyond the control of the Company. Accordingly, the Series H Preferred Shares are presented as temporary equity. For the year ended December 31, 2023, the Company issued 4,714,560 common shares for the conversion of 33,002 Series H Preferred Shares. For the year ended December 31, 2022, no Series H Preferred Shares were converted.

(“Gryphon”), under which Gryphon agreed to be the exclusive provider of any and all management services for all of the Company’s blockchain and cryptocurrency-related operations including but not limited to services relating to all mining equipment owned, purchased, leased, operated, or otherwise controlled by the Company at any location (collectively, the “Services”) unless the Gryphon MSA is terminated by the Company. On December 29, 2021, the Company and Gryphon entered into Amendment No. 1 to the Gryphon MSA (the “Gryphon MSA Amendment”) which extended the initial term of the Gryphon MSA to five years as the Company did not receive delivery of a specified minimum number of digital mining machines during 2022. Subject to written notice from the Company and an opportunity by Gryphon to cure for a period of up to 180 days, the Gryphon MSA provided the Company with the right terminate the Gryphon MSA in the event of: (i) Gryphon’s failure to perform the Services under the Gryphon MSA in a professional and workmanlike manner in accordance with generally recognized digital mining industry standards for similar services, or (ii) Gryphon’s gross negligence, fraud or willful misconduct in connection with performing the Services. Gryphon shall be entitled to specific performance or termination for cause in the event of a breach by the Company, subject to written notice and an opportunity to cure for a period of up to 180 days.

Under the GC Data Center MA, the monthly service fee is payable based on the actual hashrate performance of the equipment per miner type per location as a percentage of the anticipated monthly hashrate per miner type. A deposit of $0.5 million previously paid to Compute North for the last two months of monthly service fees was remitted to GC Data Center on behalf of the Company and is included in prepaid digital hosting services at December 31, 2023.

As part of the agreement, Core Scientific will provide digital mining fleet management and monitoring solution, Minder™, data analytics, alerting, monitoring, and miner management services.

Extended Warranty

The Company had nil and $6,700 in deferred costs included in other current and non-current assets related to deferred service revenue at December 31, 2023 and 2022, respectively. Changes in the liability for deferred revenue associated with extended warranties and service contracts were as follows (in thousands):

Litigation

The Company is, from time to time, subject to claims and suits arising in the ordinary course of business. The Company cannot predict the final outcome of such proceedings. Where appropriate, the Company vigorously defends such claims, lawsuits and proceedings. Paid expenses related to the defense of such claims are recorded by the Company as incurred and paid. On the basis of current information, the Company does not believe there is a reasonable possibility that a material loss, if any, will result from any claims, lawsuits and proceedings to which the Company is subject to either individually, or in the aggregate.

On April 7, 2023, the Company filed a suit against Gryphon in the U.S. District Court for the Southern District of New York. The Company alleges, among other things, that Gryphon materially breached its obligations to the Company, both its contractual duties under the Gryphon MSA dated August 19, 2021, and its fiduciary duties, including as a custodian of the Company’s assets. On August 22, 2023, Gryphon asserted counterclaims alleging breach of contract, breach of the implied covenant of good faith and fair dealing, negligence in managing its computer systems, and defamation. On November 7, 2023, Gryphon voluntarily dismissed its defamation claim. Gryphon has amended its complaint several times, and on December 14, 2023, added a second breach of contract claim predicated on another alleged breach of the Gryphon MSA. On February 2, 2024, the Company filed a partial motion to dismiss the second breach of contract claim, the negligence claim, and the breach of the implied covenant claim for failure to state a claim. On February 16, 2024, the court so-ordered a stipulation agreed to by the parties dismissing the second breach of contract claim, the negligence claim, and the breach of the implied covenant claim with prejudice. The so-ordered stipulation expressly preserves the Company’s ability to seek the recovery of its costs and attorney’s fees incurred in connection with the dismissed claims. The Company disputes the allegations against it and intends to vigorously defend itself and to vigorously pursue its claims against Gryphon. At this preliminary stage, the Company believes that Gryphon’s claims lack merit; however, because this litigation is still at this early stage, the Company cannot reasonably estimate the likelihood of an unfavorable outcome or the magnitude of such an outcome, if any.

Depreciation expense for property and equipment was $4.2 million and $1.7 million during the years ended December 31, 2023 and 2022, respectively, inclusive of ROU asset amortization of $56,000 and $14,000, respectively. On December 28, 2023, the Company sold its service and product segment which included the ROU asset.

During the years ended December 31, 2023 and 2022, the Company sold 3,336 and nil miners that were included in mining equipment, for cash proceeds of $4.5 million and nil, respectively. The Company had a loss on the sale of miners of $1.0 million and nil during the years ended December 31, 2023 and 2022, respectively.

Impairment of Mining Equipment

For the year ended December 31, 2022, adverse changes in the business climate, including the decline in the price of Bitcoin and two vendor bankruptcy filings, indicated that an impairment triggering event occurred, and it was determined the carrying value of mining equipment exceeded its estimated fair value. In measuring fair value, the Company used a weighted probability of the income and market approaches. For the income approach, the Company used discounted cash flow analysis and for the market approach, the Company used the sales price (market price) of similar assets. The Company compared the indicated fair value to the carrying value of its mining equipment assets, and as a result of the analysis, an impairment charge of $75.9 million was recorded for the year ended December 31, 2022. The estimated fair value of the Company’s miners is classified in Level 3 of the fair value hierarchy. The Company did not incur any impairment charges for its mining equipment for the year ended December 31, 2023.

Income Tax Disclosure [Abstract]

Income Tax Disclosure [Text Block]

Income Taxes

The Company is subject to taxation in Canada and also in certain foreign tax jurisdictions. The Company's tax returns for calendar year 2016 and forward are subject to examination by the Canadian tax authorities. The Company's tax returns for fiscal year 2019 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.

At December 31, 2023, there were no unrecognized tax benefits. 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, 2023 and 2022, and recognized no interest and/or penalties in the consolidated statements of operations for the years ended December 31, 2023 and 2022.

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

The Company’s consolidated financial instruments include cash equivalents, accounts receivable, notes receivable, accounts payable, accrued liabilities, and warrant liabilities. 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, notes receivable, accounts payable and accrued liabilities are generally considered to be representative of their respective fair values because of the short-term nature of those instruments.

The following tables provide a summary of the financial instruments that are measured at fair value on a recurring basis (in thousands):


	December 31, 2023
	Fair Value		Level 1		Level 2		Level 3

Warrant liabilities	$	205	$	—	$	—	$	205


	December 31, 2022
	Fair Value		Level 1		Level 2		Level 3
Warrant liabilities	$	864	$	864	$	—	$	—

At December 31, 2023, the fair value of the LDA Warrant was measured using a Black Scholes valuation model. The fair value of the warrants at December 31, 2022 issued in connection with MEOA's public offering were measured based on the listed market price of such warrants.

The following table presents the activities of warrant liabilities that are measured at fair value (in thousands):


Warrant liability as of January 1, 2022	$	—
Issuance of MEOA warrant	864
Warrant liability as of December 31, 2022	864
Issuance of LDA warrant	976

Noncash exercise of LDA warrant	(411)
Change in fair value LDA warrant	(112)

Warrant liability as of December 31, 2023	$	205

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

As discussed in Note 2, Summary of Significant Accounting Policies, to the Consolidated Financial Statements, the Company accounts for its Bitcoin as indefinite-lived intangible assets, which are subject to impairment losses if the fair value of its Bitcoin held decreases below their carrying value during the reporting period.

The Company's non-financial assets such as property and equipment and intangible assets are recorded at fair value when an impairment is recognized or at the time acquired in an asset acquisition or business combination measured using significant unobservable inputs (Level 3). As discussed in Note 8 - Intangible Assets, at December 31, 2023 and 2022, 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. As discussed in Note 6 - Investments and Note 7 - Certain Balance Sheet Items, at December 31, 2022, the Company recorded impairment charges associated with investments and property and equipment and reduced the carrying amount of such assets subject to the impairment to their estimated fair value

Discontinued Operations and Disposal Groups [Abstract]
Disposal Groups, Including Discontinued Operations, Disclosure [Text Block]	Disposal of Service and Product - Related Party Transaction On December 28, 2023, the Company and Joseph O’Daniel (“Purchaser”), entered into a share purchase agreement under which the Company sold its service and product segment, which included HVE ConneXions and Unified ConneXions, for $1.00 and the transfer of outstanding assets and liabilities. As a result of the share purchase agreement, the Purchaser, who served as the Company’s President, resigned effective December 28, 2023 and is no longer a related party of the Company. Through December 28, 2023, the service and product segment provided network operations center (“NOC”) services to its customers. NOC revenues were for monthly services performed for the customer that are performed either in-house or at the customer’s site. The service and product segment also delivered data management and desktop and application virtualization solutions through hybrid cloud, cloud and on premise implementations by a reseller network. During the year ended December 31, 2023, the Company recognized a noncash gain of $0.7 million related to the transfer of net liabilities to the Purchaser.

Significant Accounting Policies (Policies)	12 Months Ended
Significant Accounting Policies (Policies)	Dec. 31, 2023
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. Subsidiaries in which controlling interests are maintained are consolidated. 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 disclosure of contingent assets and liabilities at the date of the financial statements and reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates.
Reclassification, Comparability Adjustment	Reclassifications Certain prior period amounts have been reclassified for consistency with the current period presentation. The reclassifications did not have a material impact on the Company's consolidated financial statements and related disclosures.
Foreign Currency Transactions and Translations Policy [Policy Text Block]	Foreign Currency Translation The financial statements of the Company’s foreign subsidiary, for which the functional currency is the local currency, is 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 accumulated 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, Restricted Cash and Cash Equivalents, Policy	Cash and 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 Company maintains cash and cash equivalent balances with financial institutions that exceed federally insured limits. The Company has not experienced any losses related to these balances and believes credit risk to be minimal. Restricted Cash Restricted cash is cash held in a separate bank account with restrictions on withdrawal. The Company’s restricted cash was classified as current and pledged as collateral for a standby letter of credit for the bonding purpose necessary for the Company to receive mining machines and was released in 2023. Funds held in trust account were restricted and invested in U.S. government treasury money market funds. During the year ended December 31, 2023, the proceeds were released from the trust account to MEOA for the redemption of its redeemable public shares as MEOA was unable to complete the required business combination.
Accounts Receivable [Policy Text Block]	Accounts Receivable Accounts receivable is recorded at the invoiced amount and is non-interest bearing. The Company estimates its 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, the Company analyzes 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. The Company reviews the allowance for doubtful accounts on a quarterly basis and records adjustments as considered necessary. Customer accounts are written-off against the allowance for doubtful accounts when an account is considered uncollectable.
Digital Assets, Policy	Digital Assets The Company accounts for its digital assets, Bitcoin, as indefinite-lived intangible assets. The digital assets are recorded at cost less impairment. An impairment analysis is performed daily to determine if the fair value of Bitcoin is lower than the Company’s carrying value for Bitcoin until the Company’s Bitcoin is disposed of or until the end of the reporting period, whichever comes first. The fair value of digital assets is determined on a nonrecurring basis based on the lowest intraday quoted price as reported in the Company’s principal market. If the carrying value of the digital asset exceeds the fair value an impairment loss has occurred with respect to those digital assets in the amount equal to the difference between their carrying values and the fair value determined. Impairment losses are recognized in operating costs and expenses in the consolidated statements of operations in the period in which the impairment is identified. The impaired digital assets are written down to their fair value at the time of impairment and this new cost basis will not be adjusted upward for any subsequent increase in fair value. Gains are not recorded until realized upon sale or disposition. Digital assets awarded to the Company through its mining activities are included within operating activities on the accompanying consolidated statements of cash flows. The disposal of digital assets are included within operating activities in the accompanying consolidated statements of cash flows and any realized gains or losses from such sales are included in operating costs and expenses in the consolidated statements of operations. The Company accounts for its gains or losses in accordance with the first in first out (FIFO) method of accounting.
Receivables, Trade and Other Accounts Receivable, Allowance for Doubtful Accounts, Policy	Allowance for Credit Losses The Company’s assessment of its allowance for credit losses requires it to incorporate considerations of historical information, current conditions and reasonable and supportable forecasts. The Company manages credit risk through review of available public company information. For the Company’s note receivable, as of December 31, 2023, the Company has recorded an allowance for credit losses and elected to write off accrued interest receivables by reversing interest income.
Equity Securities without Readily Determinable Fair Value [Policy Text Block]	Investments The Company holds investments in equity securities of public and nonpublic companies for business and strategic purposes. Nonpublic equity securities that do not have a readily determinable fair value are carried at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. The Company reviews its investments on a regular basis to determine if the investments are impaired. For purposes of this assessment, the Company considers the investee’s cash position, earnings and revenue outlook, liquidity and management ownership, among other factors, in its review. If management’s assessment indicates that an impairment exists, the Company estimates the fair value of the equity investment and recognizes in current earnings an impairment loss that is equal to the difference between the fair value of the equity investment and its carrying amount.
Lessee, Leases	Leases The Company enters into operating leases primarily for real estate. The Company determines if an arrangement contains a lease at inception. Right of use (“ROU”) assets and liabilities resulting from operating leases are included in property and equipment, other current liabilities and other non-current liabilities on our consolidated balance sheets. Operating lease ROU assets and liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. As the leases typically do not provide an implicit rate, the Company uses the incremental borrowing rate based on the information available at commencement date in determining the discount rate to calculate the present value of future payments. The operating lease ROU asset may also include any lease payments made and exclude lease incentives and initial direct costs incurred. The Company’s leases do not include options to extend the lease. Short-term leases with an initial term of 12 months or less are not recorded on the balance sheet. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term. On December 28, 2023, the Company sold its Service and Product segment and no longer has any operating leases or ROU assets and liabilities as of December 31, 2023.
Property and Equipment, Policy [Policy Text Block]	Property and Equipment Property and equipment primarily consists of mining equipment and is stated at cost, including purchase price and all shipping and custom fees, and depreciated using the straight-line method over the estimated useful lives of the assets, generally five years. The Company reviews the carrying amounts of property and equipment when events or changes in circumstances indicate the assets may not be recoverable. If any such indication exists, the fair value of the asset is estimated in order to determine the extent of the impairment loss, if any.
Intangible Assets, Policy [Policy Text Block]	Intangible Assets 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 five years to 15 years for supplier agreements, six years for channel partner relationships, and seven years for customer relationships as this method most closely reflects the pattern in which the economic benefits of the assets will be consumed. The Company has purchased carbon credits. As it intends to use these carbon credits, the assets have been classified as intangible assets. When the carbon credit is used, it is expensed as an operating expense.
Impairment or Disposal of Long-Lived Assets, Including Intangible Assets, Policy [Policy Text Block]	Impairment of Intangible Assets The Company performs regular reviews of intangible assets to determine if any event has occurred that may indicate that intangible assets with finite useful lives and other long-lived assets are potentially impaired. 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.
Warrant Liabilities [Policy Text Block]	Warrant Liabilities Warrant liabilities are for a common share purchase warrant issued in connection with previously outstanding convertible debt, and warrants for shares of MEOA’s common stock that are not indexed to its own stock. Warrants are presented as liabilities at fair value on the consolidated balance sheets. The warrants are subject to remeasurement at each balance sheet date and any change in fair value is recognized in interest income and other expense, net, in the consolidated statements of operations.
Consolidation, Subsidiaries or Other Investments, Consolidated Entities, Policy [Policy Text Block]	Redeemable Non-controlling Interest Redeemable non-controlling interest is interest in a subsidiary of the Company that are redeemable outside of the Company’s control either for cash or other assets. This interest is classified as temporary equity and measured at the estimated redemption value at the end of each reporting period. The resulting increases or decreases in the estimated redemption amount are effected by corresponding charges to accumulated deficit. At December 31, 2022, redeemable non-controlling interest recorded within the Company’s consolidated balance sheet relates to its subsidiary, MEOA. At December 31, 2023, redeemable non-controlling interest was no longer subject to consolidation with the Company.
Revenue [Policy Text Block]	Revenue Recognition The Company accounts for revenue pursuant to ASU 2014-09, Revenue from Contracts with Customers and all the related amendments (“Topic 606”). 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, and contract consideration will be recognized on a “sell-in basis” or when control of the purchased goods or services transfer to the distributor. The Company is engaged with digital asset mining pool operators to provide computing power to the mining pools. In exchange for providing computing power, the Company is entitled to Full Pay Per Share (“FPPS”), which is a fractional share of the fixed Bitcoin award the mining pool operator receives, plus a fractional share of the transaction fees attached to that blockchain less net digital asset fees due to the mining pool operator over the measurement period, as applicable. The pay-outs received are based on the expected value from the block reward plus the transaction fee reward, regardless of whether the mining pool operator successfully records a block to the blockchain. The Company’s fractional share is based on the proportion of computing power the Company contributed to the mining pool operator to the total computing power contributed by all mining pool participants in solving the current algorithm. The contracts are terminable at any time by either party without compensation and the Company’s enforceable right to compensation only begins when the Company starts providing computing power to the mining pool operator (which occurs daily at midnight Universal Time Coordinated (“UTC”)). The contract arises at the point that the Company provides computing power to the mining pool operator, which is beginning contract day at midnight UTC (contract inception), as customer consumption is in tandem with daily earnings of delivery of the computing power. According to the customer contract, daily earnings are calculated from midnight-to-midnight UTC time, and the sub-account balance is credited one hour later at 1:00 AM UTC time. The Company satisfies its performance obligation over time with daily settlement in Bitcoin. The Company’s performance is completed as it transfers the computing power (hashrate computations) over-time (midnight to midnight) to the customer. The Company has full control of the mining equipment utilized in the mining pool and if the Company determines it will increase or decrease the processing power of its machines and/or fleet (i.e., for repairs or when power costs are excessive) the computing power provided to the customer will be adjusted. The transaction consideration the Company receives is noncash consideration in the form of Bitcoin, which the Company measures at fair value at contract inception. The noncash consideration is variable, since the amount of block reward earned depends on the amount of computing power contributed, the amount of transaction fees awarded and operator fees over the same period. The Company does not constrain this variable consideration because it is probable that a significant reversal in the amount of revenue recognized from the contract will not occur when the uncertainty is subsequently resolved and recognizes the noncash consideration on the same day that control is transferred, which is the same day as contract inception. Expenses associated with running the Bitcoin mining operations, such as hosting, operating supplies, utilities and monitoring services are recorded as cost of revenues. The Company also generates revenue from: (i) solutions for standalone storage and integrated hyper-converged storage; (ii) professional services; and (iii) warranty and customer services. The Company recognizes revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services. To determine revenue recognition for contracts with customers the Company performs the following five steps: (i) identify the promised goods or services in the contract; (ii) identify the performance obligations in the contract, including whether they are distinct in the context of the contract; (iii) determine the transaction price, including the constraint on variable consideration; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the Company satisfies the performance obligations. The majority of the Company’s product and service revenue is recognized when performance obligations under the terms of a contract with a customer are satisfied at a point in time. These contracts are generally comprised of a single performance obligation to transfer products. Accordingly, the Company recognizes revenue when change of control has been transferred to the customer, generally at the time of shipment of products. The Company sells its products both directly to customers and through distributors generally under agreements with payment terms typically less than 45 days. Revenue on direct product sales, excluding sales to distributors, 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. Product sales to distribution customers that are subject to certain rights of return, stock rotation privileges and price protections, contain a component of “variable consideration.” Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring products and is generally based upon a negotiated fixed price and is net of estimates for variable considerations. For performance obligations related to warranty and customer services, such as extended product warranties, the Company transfers control and recognizes revenue on a time-elapsed basis. The performance obligations are satisfied as services are rendered typically on a stand-ready basis over the contract term, which is generally 12 months. The Company also enters into revenue arrangements that may consist of multiple performance obligations of its product and service offerings such as for sales of hardware devices and extended warranty services. The Company allocates contract fees to the performance obligations on a relative stand-alone selling price basis. The Company determines the stand-alone selling price based on its normal pricing and discounting practices for the specific product and/or service when sold separately. When the Company is unable to establish the individual stand-alone price for all elements in an arrangement by reference to sold separately instances, the Company may estimate the stand-alone selling price of each performance obligation using a cost plus a margin approach, by reference to third party evidence of selling price, based on the Company’s actual historical selling prices of similar items, or based on a combination of the aforementioned methodologies; whichever management believes provides the most reliable estimate of stand-alone selling price.
Extended Product Warranty, Policy [Policy Text Block]	Extended Warranty Separately priced extended on-site warranties and service contracts are offered for sale to customers on all product lines. Extended warranty and service contract revenue and recognized as service revenue over the period of the service agreement. The Company will typically apply the practical expedient to agreements wherein the period between transfer of any good or service in the contract and when the customer pays for that good or service is one year or less. On December 28, 2023, the Company sold its service and product segment and no longer has any deferred revenue for extended on-site warranties and service contracts as of December 31, 2023.
Shipping and Handling Cost, Policy [Policy Text Block]	Shipping and Handling Amounts billed to customers for shipping and handling are included in revenue, and costs incurred related to shipping and handling are included in cost of product revenue.
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. Research and development expenses are charged to operating expenses as incurred when these expenditures relate to the Company’s research and development efforts and have no alternative future uses.
Segment Reporting, Policy [Policy Text Block]	Segment Information Operating segments are defined as components of an enterprise for which separate financial information is available and evaluated regularly by the chief operating decision maker, or decision-making group, in deciding the method to allocate resources and assess performance. Through the period ended December 28, 2023, the Company had two operating segments. On December 28, 2023, the Company sold its service and product segment.
Income Tax, Policy [Policy Text Block]	Income Taxes The Company provides 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 (Loss), Policy [Policy Text Block]	Comprehensive Income (Loss) Comprehensive income (loss) and its components encompass 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, the Company performs ongoing credit evaluations of its customers and maintain allowances for potential credit losses for estimated bad debt losses.
Share-based Payment Arrangement [Policy Text Block]	Share-based Compensation The Company accounts for share-based awards, and similar equity instruments, granted to employees, non-employee directors, and consultants in accordance with the authoritative guidance for share-based compensation. Share-based compensation award types may include stock options and restricted stock units (“RSUs”) and restricted stock awards (“RSAs”). Share-based compensation expense is recognized on a straight-lined basis over the requisite service period (usually the vesting period) except for options with graded vesting which is recognized pursuant to an accelerated method. Forfeitures are recognized as a reduction in share-based compensation expense as they occur.
Non-controlling Interest, Policy [Policy Text Block]	Non-controlling Interest The Company accounts for its non-controlling interest in accordance with the authoritative guidance for consolidation which governs the accounting for and reporting of non-controlling interests (“NCIs”) in partially owned consolidated subsidiaries and the loss of control of subsidiaries. Certain provisions of the guidance indicate, among other things, that NCIs be treated as a separate component of equity, not as a liability, that increases and decreases in the parent’s ownership interest that leave control intact be treated as equity transactions rather than as step acquisitions or dilution gains or losses, and that losses of a partially owned consolidated subsidiary be allocated to the NCI even when such allocation might result in a deficit balance. The net income (loss) attributed to the NCI is separately designated in the accompanying consolidated statements of operations. At December 31, 2023, the Company no longer owned a controlling interest in MEOA and as such the non-controlling interest was no longer subject to consolidation with the Company.
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. In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires public entities with a single reportable segment to provide all the disclosures required by this standard and all existing segment disclosures in Topic 280 on an interim and annual basis, including new requirements to disclose significant segment expenses that are regularly provided to the chief operating decision maker (“CODM”) and included within the reported measure(s) of a segment's profit or loss, the amount and composition of any other segment items, the title and position of the CODM, and how the CODM uses the reported measure(s) of a segment's profit or loss to assess performance and decide how to allocate resources. The guidance is effective for annual periods beginning after December 15, 2023, and interim periods beginning after December 15, 2024, applied retrospectively with early adoption permitted. The Company is evaluating the impact of adoption of this standard on its consolidated financial statements and disclosures. In December 2023, the FASB issued ASU 2023-08, Intangibles - Goodwill - and Other - Crypto Assets (Subtopic 350-60): Accounting For and Disclosure of Crypto Assets, which requires that an entity measure crypto assets at fair value in the statement of financial position each reporting period and recognize changes from remeasurement in net income. The amendments also require that an entity provide enhanced disclosures for both annual and interim reporting periods to provide investors with relevant information to analyze and assess the exposure and risk of significant individual crypto asset holdings. In addition, fair value measurement aligns the accounting required for holders of crypto assets with the accounting for entities that are subject to certain industry-specific guidance and eliminates the requirement to test those assets for impairment, thereby reducing the associated cost and complexity of applying the current guidance. The guidance is effective for annual periods beginning after December 15, 2024, and interim periods beginning after December 15, 2024, applied retrospectively with early adoption permitted. The Company expects to early adopt the new standard effective January 1, 2024 and does not expect a material impact on its consolidated financial statements and disclosures. In December 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures, which requires more detailed income tax disclosures. The guidance requires entities to disclose disaggregated information about their effective tax rate reconciliation as well as expanded information on income taxes paid by jurisdiction. The disclosure requirements will be applied on a prospective basis, with the option to apply them retrospectively. The standard is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. The Company is evaluating the disclosure requirements related to the new standard. Recently Adopted Accounting Pronouncements In June 2016, the FASB issued Accounting Standards Update No. 2016-13, Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”). ASU 2016-13 amends the impairment model by requiring entities to use a forward-looking approach based on expected losses to estimate credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. Entities will no longer be permitted to consider the length of time that fair value has been less than amortized cost when evaluating when credit losses should be recognized. The Company adopted ASU 2016-13 on January 1, 2023 on a modified retrospective basis which resulted in a $3.8 million increase to the opening balance of accumulated deficit, representing the cumulative allowance for credit losses for the Company’s note receivable. In October 2021, the FASB issued Accounting Standards Update No. 2021-08, Accounting for Contract Assets and Contract Liabilities from Contracts with Customers (“ASU 2021-08”). ASU 2021-08 amends ASC 805 to require acquiring entities to apply Topic 606 to recognize and measure contract assets and contract liabilities in a business combination. The Company adopted the new standard beginning January 1, 2023, however it did not have an effect on its financial position, results of operations or cash flows.
