Reclassification

Certain amounts in prior periods have been reclassified to conform to current period presentation. These reclassifications had no effect on the previously reported net loss.

Fair Value of Financial Instruments

Fair value of financial instruments

The Company follows Accounting Standards Codification (“ASC”) 820–10 “Fair Value Measurement” of the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification to measure the fair value of its financial instruments and disclosures about fair value of its financial instruments. ASC 820–10 establishes a framework for measuring fair value and expands disclosures about fair value measurements. To increase consistency and comparability in fair value measurements and related disclosures, ASC 820–10 establishes a fair value hierarchy which prioritizes the inputs to valuation techniques used to measure fair value into three (3) broad levels.

The three (3) levels of fair value hierarchy defined by ASC 820–10 are described below:

Level 1		Quoted market prices available in active markets for identical assets or liabilities as of the reporting date.

Level 2		Pricing inputs other than quoted prices in active markets included in Level 1, which are either directly or indirectly observable as of the reporting date.

Level 3		Pricing inputs that are generally unobservable inputs and not corroborated by market data.

Financial assets are considered Level 3 when their fair values are determined using pricing models, discounted cash flow methodologies or similar techniques and at least one significant model assumption or input is unobservable.

The fair value hierarchy gives the highest priority to quoted prices (unadjusted) in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. If the inputs used to measure the financial assets and liabilities fall within more than one level described above, the categorization is based on the lowest level input that is significant to the fair value measurement of the instrument.

The carrying amounts of the Company’s financial assets and liabilities, such as cash, prepaid expenses and other current assets, accounts payable and accrued expenses approximate their fair values due to the short-term nature of these instruments.

The Company had no Level 3 financial assets or liabilities as of December 31, 2017 and 2016.

The Company uses Level 1 of the fair value hierarchy to measure the fair value of investments in certain common equity securities as well as digital currencies. The Company revalues such assets at every reporting period and recognizes gains or losses as revenue and cost of revenue respectively in the consolidated statements of operations that are attributable to the change in the fair value of the digital currencies.

The following table provides the financial assets measured on a recurring basis and reported at fair value on the balance sheet as of December 31, 2017:

			Fair value measurement using
	Carrying value		Level 1		Level 2		Level 3		Total
Digital currencies	$	48	$	48	$	–	$	–	$	48

Revenue Recognition

Revenue recognition

The Company recognizes revenue when it is realized or realizable and earned. The Company considers revenue realized or realizable and earned when there is persuasive evidence of an arrangement, delivery has occurred, the sales price is fixed or determinable and collectability is probable. The Company’s primary revenue stream is related to the mining of digital currencies. The Company derives its revenue by solving “blocks” to be added to the blockchain and providing transaction verification services within the digital currency networks of cryptocurrencies, such as Bitcoin and Ethereum, commonly termed “cryptocurrency mining.” In consideration for these services, the Company receives digital currency (“Coins”). The Coins are recorded as revenue, using the average spot price of Bitcoin on the date of receipt. The Coins are recorded on the balance sheet at their fair value and re–measured at each reporting date. Revaluation gains or losses, as well gains or losses on sale of coins are recorded as revenue and cost of revenue, respectively in the consolidated statements of operations. Expenses associated with running the cryptocurrency mining business, such as equipment depreciation, rent and electricity cost are recorded as costs of revenues.

Loss Per Share

Loss per share

Basic loss per share is calculated by dividing net loss applicable to common shareholders by the weighted average number of common shares outstanding during the period. Diluted loss per share is calculated by dividing the net loss attributable to common shareholders by the sum of the weighted average number of common shares outstanding plus potential dilutive common shares outstanding during the period. Potential dilutive securities, comprised of unvested restricted shares, convertible debt stock warrants and stock options, are not reflected in diluted net loss per share because such potential shares are anti–dilutive due to the Company’s net loss.

Accordingly, the computation of diluted loss per share for the year ended December 31, 2017, excludes 2,000,000 shares issuable to the investors of the December 2017 private placement, 3,381,816 shares issuable to UAHC Ventures, LLC a Nevada limited liability company (“UAHC”) due to the conversion of the UAHC note payable, 3,850,000 unvested restricted shares, 6,000,000 shares issuable under stock options, and 13,720,742 shares issuable under warrants. The computation of diluted loss per share for the year ended December 31, 2016, excluded 3,000,000 unvested restricted shares, 2,300,000 shares issuable upon the conversion of convertible notes, 6,000,000 shares issuable under stock options and 100,000 shares issuable under warrants.

Stock-Based Compensation

Stock–based compensation

The Company recognizes compensation expense for all equity–based payments in accordance with ASC 718 “Compensation – Stock Compensation”. Under fair value recognition provisions, the Company recognizes equity–based compensation net of an estimated forfeiture rate and recognizes compensation cost only for those shares expected to vest over the requisite service period of the award.

Restricted stock awards are granted at the discretion of the compensation committee of the Board of Directors of the Company. These awards are restricted as to the transfer of ownership and generally vest over the requisite service periods, typically over an 18 to 24-month period (vesting on a straight–line basis). The fair value of a stock award is equal to the fair market value of a share of the Company’s common stock on the grant date.

The fair value of an option award is estimated on the date of grant using the Black–Scholes option valuation model. The Black–Scholes option valuation model requires the development of assumptions that are inputs into the model. These assumptions are the expected stock volatility, the risk–free interest rate, the expected life of the option, the dividend yield on the underlying stock and the expected forfeiture rate. Expected volatility is calculated based on the historical volatility of the Company’s common stock over the expected term of the option. Risk–free interest rates are calculated based on continuously compounded risk–free rates for the appropriate term.

Determining the appropriate fair value model and calculating the fair value of equity–based payment awards requires the input of the subjective assumptions described above. The assumptions used in calculating the fair value of equity–based payment awards represent management’s best estimates, which involve inherent uncertainties and the application of management’s judgment. The Company is required to estimate the expected forfeiture rate and recognize expense only for those shares expected to vest. The fair value of unvested equity instruments is re-measured each reporting period and such re-measured value is amortized over the requisite remaining service period.

The Company accounts for share–based payments granted to non–employees in accordance with ASC 505–50, “Equity Based Payments to Non–Employees”. The Company determines the fair value of the stock–based payment as either the fair value of the consideration received or the fair value of the equity instruments issued, whichever is more readily determinable. If the fair value of the equity instruments issued is used, it is measured using the stock price and other measurement assumptions as of the earlier of either (1) the date at which a commitment for performance by the counterparty to earn the equity instruments is reached, or (2) the date at which the counterparty’s performance is complete.

Investments Available for Sale

Investments available for sale

Equity security investments available for sale, at market value, reflect unrealized appreciation and depreciation, as a result of temporary changes in market value during the period, in shareholders’ equity, net of income taxes in “accumulated other comprehensive income (loss)” in the consolidated balance sheets. For non–publicly traded securities, market prices are determined through the use of pricing models that evaluate securities. For publicly traded securities, market value is based on quoted market prices or valuation models that use observable market inputs.

Intangible Assets

Intangible assets

Intangible assets consisted of the Sentinel network intrusion detection device, all underlying software and firmware, the server contract, and case and circuit board inventory that the Company acquired from Cyberdonix, Inc, an Alabama corporation (“Cyberdonix”), in October 2016. Estimates of future cash flows and timing of events for evaluating long–lived assets for impairment are based upon management’s judgment. If any of our intangible or long–lived assets are considered to be impaired, the amount of impairment to be recognized is the excess of the carrying amount of the assets over its fair value. Applicable long–lived assets are amortized or depreciated over the shorter of their estimated useful lives, the estimated period that the assets will generate revenue, or the statutory or contractual term in the case of patents. Estimates of useful lives and periods of expected revenue generation are reviewed periodically for appropriateness and are based upon management’s judgment. As of December 31, 2017, the Company had impaired its remaining intangible assets.

Recent Accounting Pronouncements

Recent accounting pronouncements

Management does not believe that any recently issued, but not yet effective accounting pronouncements, when adopted, will have a material effect on the accompanying consolidated financial statements, other than those disclosed below.

In May 2014, the FASB issued Accounting Standards Update (“ASU”) 2014-09, “Revenue from Contracts with Customers (Topic 606).” The guidance requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The FASB delayed the effective date to annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Earlier application is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. In addition, in March and April 2016, the FASB issued new guidance intended to improve the operability and understandability of the implementation guidance on principal versus agent considerations. Both amendments permit the use of either a retrospective or cumulative effect transition method and are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, with early application permitted. The Company expects to implement ASU 2014-09, on January 1, 2018 pursuant to which it will utilize the modified retrospective approach. The Company does not believe that ASU 2014-09 will have a material impact on its consolidated financial statements.

In February 2016, FASB issued ASU No. 2016–02, “Leases (Topic 842)”, which creates new accounting and reporting guidelines for leasing arrangements. The new guidance requires organizations that lease assets to recognize assets and liabilities on the balance sheet related to the rights and obligations created by those leases, regardless of whether they are classified as finance or operating leases. Consistent with current guidance, the recognition, measurement, and presentation of expenses and cash flows arising from a lease primarily will depend on its classification as a finance or operating lease. The guidance also requires new disclosures to help financial statement users better understand the amount, timing, and uncertainty of cash flows arising from leases. The new standard is effective for annual reporting periods beginning after December 15, 2018, including interim periods within that reporting period, with early application permitted. The Company is currently evaluating the impact of the new pronouncement on its consolidated financial statements.

In August 2016, the FASB issued ASU 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments”. ASU 2016-15 provides guidance for eight specific cash flow issues with respect to how cash receipts and cash payments are classified in the statements of cash flows, with the objective of reducing diversity in practice. The effective date for ASU 2016-15 is for annual periods beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted. The Company expects to implement ASU 2016-15 on January 1, 2018 and does not believe it will have a material impact on its consolidated financial statements.

In January 2017, the FASB issued ASU 2017-04, “Intangibles – Goodwill and Other” (Topic 350). The amendments in this update simplify the test for goodwill impairment by eliminating Step 2 from the impairment test, which required the entity to perform procedures to determine the fair value at the impairment testing date of its assets and liabilities following the procedure that would be required in determining fair value of assets acquired and liabilities assumed in a business combination. The amendments in this update are effective for public companies for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. The Company is evaluating the impact of adopting this guidance on its consolidated financial statements.

In January 2017, the FASB issued ASU 2017-01, “Business Combinations” (Topic 805), Clarifying the Definition of a Business. The amendments in this update clarify the definition of a business to help companies evaluate whether transactions should be accounted for as acquisitions or disposals of assets or businesses. The amendments in this update are effective for public companies for annual periods beginning after December 15, 2017, including interim periods within those periods. The Company expects to implement ASU 2017-01 on January 1, 2018 and does not believe it will have a material impact on its consolidated financial statements.

In July 2017, the FASB issued ASU 2017-11, “Earnings Per Share (Topic 260), Distinguishing Liabilities from Equity (Topic 480) and Derivatives and Hedging (Topic 815): I. Accounting for Certain Financial Instruments with Down Round Features; II. Replacement of the Indefinite Deferral for Mandatorily Redeemable Financial Instruments of Certain Nonpublic Entities and Certain Mandatorily Redeemable Non-controlling Interests with a Scope Exception”. Part I of this update addresses the complexity of accounting for certain financial instruments with down round features. Down round features are features of certain equity-linked instruments (or embedded features) that result in the strike price being reduced on the basis of the pricing of future equity offerings. Current accounting guidance creates cost and complexity for entities that issue financial instruments (such as warrants and convertible instruments) with down round features that require fair value measurement of the entire instrument or conversion option. Part II of this update addresses the difficulty of navigating Topic 480, Distinguishing Liabilities from Equity, because of the existence of extensive pending content in the FASB Accounting Standards Codification. This pending content is the result of the indefinite deferral of accounting requirements about mandatorily redeemable financial instruments of certain nonpublic entities and certain mandatorily redeemable non-controlling interests. The amendments in Part II of this update do not have an accounting effect. ASU 2017-11 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018. The Company has adopted the ASU beginning with these consolidated financial statements. As a result, the conversion features of certain of its convertible notes payable and equity instruments that contain “down round” provisions were not bifurcated and were not recorded as a derivative liability.
