Summary of Significant Accounting Policies Summary of Significant Accounting Policies
There have been no changes in significant accounting policies as described in our Annual Report on Form 10-K for the year ended December 31, 2020, except as set forth below.
Recently Adopted Accounting Pronouncements
In December 2019, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (“ASU 2019-12”). ASU 2019-12 includes the removal of certain exceptions to the general principles of ASC 740 and simplifies the accounting for income taxes by clarifying and amending existing guidance. We adopted the update January 1, 2021 and it did not have a material impact on our condensed consolidated financial statements and disclosures.
In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) ("ASU 2016-02"). We adopted ASU 2016-02 effective January 1, 2021. The core principle of ASU 2016-02 is that a lessee should recognize the assets and liabilities that arise from leases. For operating leases, a lessee is required to recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments, in the statement of financial position. We have elected certain practical expedients permitted under the transition guidance that allows us to use the beginning of the period of adoption (January 1, 2021) as the date of initial recognition. As a result, prior period comparative financial information was not recast under the new
standard and continues to be presented under the prior lease accounting standards. Other practical expedients include our election to not separate non-lease components from lease components and to not reassess lease classification, treatment of initial direct costs or whether an existing or expired contract contains a lease. We have also elected to apply the short-term lease exception for all leases, which we will not recognize right-of-use assets or lease liabilities for leases that, at the commencement date, have a term of twelve (12) months or less.
The adoption of the new lease standard on January 1, 2021, resulted in the recognition of right-of-use assets and operating lease liabilities of $2,101 on the condensed consolidated balance sheet. In connection with the adoption of this standard, short-term deferred rent of $8, which was previously recorded in accrued expenses and long term deferred rent of $180 previously recorded in deferred rent on the condensed consolidated balance sheet was offset against the right-of-use asset. The details of our right-of-use asset and lease liability recognized upon adoption of ASC 842 are set forth below:
January 1, 2021
Right-of-use asset $ 2,101 
Straight-line rent accrual (188)
$ 1,913 
Lease liability, current $ 500 
Lease liability, non-current 1,601
$ 2,101 
Concentrations of Credit Risk
Our financial instruments that are exposed to concentrations of credit risk consist primarily of cash and trade accounts receivable. Although we limit our exposure to credit loss by depositing our cash with established financial institutions that management believes have good credit ratings and represent minimal risk of loss of principal, our deposits, at times, may exceed federally insured limits. Collateral is not required for accounts receivable, and we believe the carrying value approximates fair value.
The following table sets forth our concentration of accounts receivable, net of specific allowances for doubtful accounts.
March 31, 2021 December 31, 2020
Customer A 20  % —  %
Customer B 19  % —  %
Customer C 18  % 16  %
Customer D —  % 55  %
Customer E —  % 13  %
Customer F 25  % —  %
Digital Assets
During the three months ended March 31, 2021, we purchased an aggregate of $1,098 in digital assets, comprised solely of bitcoin. We currently account for all digital assets held as a result of these transactions as indefinite-lived intangible assets in accordance with Accounting Standards Codification ("ASC") 350, Intangibles—Goodwill and Other. We have ownership of and control over our bitcoin and we may use third-party custodial services to secure it. The digital assets are initially recorded at cost and are subsequently remeasured on the condensed consolidated balance sheet at cost, net of any impairment losses incurred since acquisition.
We determine the fair value of our bitcoin on a nonrecurring basis in accordance with ASC 820, Fair Value Measurement, based on quoted prices on the active exchange(s) that we have determined is its principal market for bitcoin (Level 1 inputs). We perform an analysis each quarter to identify whether events or changes in circumstances, principally
decreases in the quoted prices on active exchanges, indicate that it is more likely than not that our digital assets are impaired. In determining if an impairment has occurred, we consider the lowest market price of one bitcoin quoted on the active exchange since acquiring the bitcoin. If the then current carrying value of a 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.
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, at which point they are presented net of any impairment losses for the same digital assets held. In determining the gain to be recognized upon sale, we calculate the difference between the sales price and carrying value of the digital assets sold immediately prior to sale. Impairment losses and gains or losses on sales are recognized within other expense in our condensed consolidated statements of operations and comprehensive loss. Impairment loss was immaterial and we did not sell any bitcoin during the three months ended March 31, 2021.
Use of Estimates
The preparation of financial statements in conformity with U.S. GAAP requires management to make certain 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 the reported amounts of revenue and expenses during the reporting period. Items subject to the use of estimates include, but are not limited to, the standalone selling price for our products and services, stock-based compensation, useful lives of long-lived assets including intangibles, fair value of intangible assets and the recoverability or impairment of tangible and intangible assets, including goodwill, reserves and certain accrued liabilities, the benefit period of deferred commissions, assumptions used in Black-Scholes valuation method, such as expected volatility, risk-free interest rate and expected dividend rate, our incremental borrowing rate in determining the present value of remaining lease payments, and provision for (benefit from) income taxes. Actual results could differ from those estimates and such differences could be material to the condensed consolidated financial statements.
Loss per Common Share
Basic loss per common share is computed by dividing net loss applicable to common stockholders by the weighted average number of shares of common stock outstanding during the period. Restricted shares subject to repurchase provisions relating to early exercises under our 2009 Equity Incentive Plan were excluded from basic shares outstanding. Diluted loss per common share is computed by giving effect to all potential shares of common stock, including those related to our outstanding warrants and stock equity plans, to the extent dilutive. For all periods presented, these shares were excluded from the calculation of diluted loss per share of common stock because their inclusion would have been anti-dilutive. As a result, diluted loss per common share is the same as basic loss per common share for all periods presented.
The following table sets forth common stock equivalents that have been excluded from the computation of dilutive weighted average shares outstanding as their inclusion would have been anti-dilutive:
March 31,
2021 2020
Convertible notes 4,920,000 21,740
Warrants 5,996,112 3,836,112
Options 1,087,033 1,381,173
Restricted stock units 5,545,454 3,124,460
Restricted shares 574 4,689
Total 17,549,173 8,368,174
Fair Value of Financial Instruments
We follow the guidance in ASC 820, Fair Value Measurement, to account for financial assets and liabilities measured on a recurring basis. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. The Company uses a fair value hierarchy, which distinguishes between assumptions based on market data (observable inputs) and an entity's own
assumptions (unobservable inputs). The guidance requires fair value measurements be classified and disclosed in one of the following three categories:
Level 1: Unadjusted quoted prices in active markets for identical assets or liabilities.
Level 2: Quoted prices in markets that are not active or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability.
Level 3: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity).
Determining which category an asset or liability falls within the hierarchy requires significant judgment. Our financial instruments measured at fair value as of March 31, 2021 are set forth below:
Level 1 Level 2 Level 3 Total
Digital currencies $ 1,098  $ —  $ —  $ 1,098 
Total $ 1,098  $ —  $ —  $ 1,098 
Warrant liability $ —  $ 2,499  $ —  $ 2,499 
Total $ —  $ 2,499  $ —  $ 2,499 

Our financial instruments measured at fair value as of December 31, 2020 are set forth below:
Level 1 Level 2 Level 3 Total
Warrant liability $ —  $ 1,614  $ —  $ 1,614 
Total $ —  $ 1,614  $ —  $ 1,614 
The carrying value of accounts receivable, prepaid expenses, other current assets, accounts payable and accrued expenses are considered to be representative of their respective fair values because of the short-term nature of those instruments.
Recent Accounting Pronouncements Not Yet Adopted
In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments ("ASU 2016-13"). ASU 2016-13 introduces a model based on expected losses for most financial assets and certain other instruments. In addition, for available-for-sale debt securities with unrealized losses, the losses will be recognized as allowances rather than reductions in the amortized cost of the securities. As a smaller reporting company, the standard is currently effective for us for annual reporting periods beginning after December 15, 2022, with early adoption permitted for annual reporting periods beginning after December 15, 2019. We currently intend to adopt this new standard effective January 1, 2023. We currently do not expect the adoption of ASU 2016-13 to have a material impact on our condensed consolidated financial statements and disclosures.
In August 2020, the FASB issued ASU 2020-06, Debt – Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic 815 – 40), (“ASU 2020-06”). ASU 2020-06 simplifies the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts on an entity’s own equity. ASU 2020-06 is effective for smaller reporting companies for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. We are currently evaluating the impact of this guidance on our condensed consolidated financial statements and disclosures.
