Risks and Uncertainties
Regulation governing blockchain technologies, cryptocurrencies, digital assets, digital asset exchanges, utility tokens, security tokens and offerings of digital assets is uncertain, and new regulations or policies may materially adversely affect the development and the value of our tokens and token ecosystem. Regulation of digital assets, like PhunCoin and PhunToken, cryptocurrencies, blockchain technologies and digital asset exchanges, is evolving and likely to continue to evolve. Regulation also varies significantly among international, federal, state and local jurisdictions and is subject to significant uncertainty. Various legislative and executive bodies in the United States and in other countries may in the future adopt laws, regulations, or guidance, or take other actions, which may severely impact the permissibility of tokens generally and the technology behind them or the means of transaction or in transferring them. Any such laws, regulations, guidance or other actions could adversely affect our ability to maintain PhunCoin and PhunToken, which could have a material adverse effect on our operations and financial condition. Failure by us to comply with any such laws and regulations, some of which may not exist yet or are subject to interpretation and may be subject to change, could also result in a material adverse effect on our operations and financial condition.
Concentrations of Credit Risk
Our financial instruments that are exposed to concentrations of credit risk consist primarily of cash, trade accounts receivable and our digital asset holdings.
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.
There is currently no clearing house for our digital assets, including our bitcoin holdings, nor is there a central or major depository for the custody of our digital assets. There is a risk that some or all of our digital asset holdings could be lost or stolen. There can be no assurance that the custodians will maintain adequate insurance or that such coverage will cover losses with respect to our digital asset holdings. Further, transactions denominated in digital assets are irrevocable. Stolen or incorrectly transferred digital assets may be irretrievable. As a result, any incorrectly executed transactions could adversely our financial condition. The aggregate cost basis (prior to impairment) of our digital asset holdings was $8,817 and $37,737 at March 31, 2023 and December 31, 2022, respectively.
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.

Our inventory balance on the dates presented consisted of the following:

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. 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:

Fair Value Measurements
We follow the guidance in ASC 820, Fair Value Measurement, to measure certain assets and liabilities on a recurring and nonrecurring 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. We use 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 assets and liabilities measured at fair value on a recurring basis as of March 31, 2023 are set forth below:
Level 1 Level 2 Level 3 Total
Warrant liability $ —  $ $ —  $
Total $ —  $ $ —  $
Our financial instruments measured at fair value on a recurring basis as of December 31, 2022 are set forth below:
Level 1 Level 2 Level 3 Total
Warrant liability $ —  $ 256  $ —  $ 256 
Total $ —  $ 256  $ —  $ 256 
The following table sets forth the assumptions used to calculate the fair values of the liability classified warrant issued in connection with our 2020 Convertible Notes as of the dates presented:

March 31, 2023 December 31, 2022
Strike price per share $ 1.42  $ 1.42 
Closing price per share $ 0.71  $ 0.77 
Term (years) 0.28 0.53
Volatility 57  % 102  %
Risk-free rate 4.97  % 4.70  %
Dividend Yield
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.
