Summary of Significant Accounting Policies | Note 2 – Summary of Significant Accounting Policies Cash and Cash Equivalents and Marketable Securities The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. The Company held $13,202,816 and $1,182,412 in cash equivalents as of June 30, 2023 and December 31, 2022, respectively. The Company held marketable securities as of June 30, 2023 as noted in the following table: Adjusted Cost Unrealized Losses Fair Value Cash and Cash Equivalents Current Marketable Securities Non-Current Marketable Securities Cash $ 14,599,361 — $ 14,599,361 $ 14,599,361 — — Level 2: U.S. Treasury securities $ — $ — $ — $ — $ — — Total $ 14,599,361 $ — $ 14,599,361 $ 14,599,361 $ — — The Company held marketable securities as of December 31, 2022 as noted in the following table: Adjusted Cost Unrealized Losses Fair Value Cash and Cash Equivalents Current Marketable Securities Non-Current Marketable Securities Cash $ 4,046,937 — $ 4,046,937 $ 4,046,937 — — Level 2: U.S. Treasury securities $ 1,963,432 $ 18,968 $ 1,944,464 $ — $ 1,944,464 — Total $ 6,010,369 $ 18,968 $ 5,991,401 $ 4,046,937 $ 1,944,464 — Accounting Standards Codification (ASC) Topic 820 “Fair Value Measurements” establishes a fair value hierarchy that prioritizes the information used to develop those assumptions. The fair value hierarchy is as follows: Level 1 Inputs - Unadjusted quoted prices in active markets for identical assets or liabilities that the entity has the ability to access at the measurement date. Level 2 Inputs - Fair value estimates are based on observable inputs other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 Inputs - Unobservable inputs for determining the fair values of assets or liabilities that reflect an entity’s own assumptions about the assumptions that market participants would use in pricing the assets or liabilities. The following is a description of valuation methodologies used for assets and liabilities recorded at an amortized cost basis: • Investment Securities Held-to-Maturity. Investment securities held-to-maturity (“HTM”) are recorded at their initial cost, and any discount or premium amortized over the remaining life of the security. The carrying value of the investment is adjusted for the amortized amount of any discount or premium at each reporting period. Accounts Receivable Accounts receivables consist of balances due from sales, service revenues, unbilled accounts receivables which is for revenues earned but not yet billed, and other receivables relating to common stock subscription purchases where the stock has been transferred but the cash has not been received. The Company monitors accounts receivable and provides allowances when considered necessary. At June 30, 2023 and December 31, 2022, accounts receivable were considered to be fully collectible but in accordance with the allowance for credit losses, the Company recorded an allowance for bad debt based on a reserve of current and aged receivables. Accordingly, an allowance for doubtful accounts of $406 and $0 was recorded as of June 30, 2023 and December 31, 2022, respectively. Accounts Receivable Accounts receivables consist of balances due from sales and service revenues and accrued interest from the investment account. Unbilled Accounts Receivable Unbilled accounts receivables consist of balances due from sales and service revenue earned but not yet billed. Accounts receivable allowance for credit losses The activity related to the accounts receivable allowance for credit losses was as follows: Name Six Months Ending at June 30, 2023 Year Ending at December 31, 2022 Beginning balance $ — $ — Current period provision 406 — Write-offs — — Ending Balance $ 406 $ — Inventories Inventories are stated at the lower of cost or net realizable value. Cost is determined on a first-in, first-out basis. The majority of our inventory is raw materials and work in progress. Net realizable value is the value of an asset that can be realized upon the sale of the asset, less a reasonable estimate of the costs associated with either the eventual sale or the disposal of the asset in question. We utilize third-party suppliers to produce our products. Costs associated with fabrication, and other costs associated with the manufacturing of products, are recorded as inventory. We periodically evaluate the carrying value of our inventories in relation to estimated forecasts of product demand, which takes into consideration the life cycle of product releases. When quantities on hand exceed estimated sales forecasts, we perform an analysis to determine if a write-down for such excess inventories is required. Once inventory has been written down, it creates a new cost basis for inventory. Inventories are classified as current assets in accordance with recognized industry practice. Property and Equipment Property and Equipment is recorded at cost. Depreciation is computed using the straight-line method and an estimated useful life of three years. Expenses for maintenance and repairs are charged to expense as incurred. Depreciation expense related to property and equipment was as follows: Period Ended June 30, 2023 2022 Depreciation $ 10,417 $ 728 Intangible Assets Intangible assets are subject to amortization, and any impairment is determined in accordance with ASC 360, “Property, Plant, and Equipment.” Intangible assets are stated at historical cost and amortized over their estimated useful lives. The Company uses a straight-line method of amortization unless a method that better reflects the pattern in which the economic benefits of the intangible asset are consumed or otherwise used up can be reliably determined. As of June 30, 2023 and December 31, 2022, there was no impairment. Long-Lived Assets The Company reviews long-lived assets, including intangible assets with finite lives, for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The Company uses an estimate of the undiscounted cash flows over the remaining life of its long-lived assets, or related group of assets where applicable, in measuring whether the assets to be held and used will be realizable. Recoverability of assets held and used is measured by a comparison of the carrying amount to the future undiscounted expected net cash flows to be generated by the asset. As of June 30, 2023 and December 31, 2022, there were no impairments. Concentrations of Credit Risk Financial instruments that potentially subject the Company to credit risk consist of cash and cash equivalents, and marketable securities. Deposits with financial institutions are insured, up to certain limits, by the Federal Deposit Insurance Corporation (“FDIC”). The Company’s cash deposits often exceed the FDIC insurance limit; however, all deposits are maintained with high credit quality institutions and the Company has not experienced any losses in such accounts. The financial condition of financial institutions is periodically reassessed, and the Company believes the risk of any loss is minimal. The Company believes the risk of any loss on cash due to credit risk is minimal. Furthermore, we perform ongoing credit evaluations of our customers and generally do not require collateral. Significant customers and suppliers are those that account for greater than 10% of the Company’s revenues and purchases. Our customer revenue for one customer made up over 90% of revenue for the period ended June 30, 2023 and year ended December 31, 2022. In 2023 and 2022, the Company purchased a substantial portion of manufacturing services from one third party vendor, Merrell Bros Fabrication, LLC. Revenue Recognition The Company follows the revenue standards of Codification (ASC) Topic 606: “Revenue from Contracts with Customers (Topic 606).” The core principle of this Topic is that an entity recognizes 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. Revenue is recognized in accordance with that core principle by applying the following five steps: 1) identify the contracts with a customer; 2) identify the performance obligations in the contract; 3) determine the transaction price; 4) allocate the transaction price to the performance obligations; and 5) recognize revenue when (or as) we satisfy a performance obligation using the input method. The Company’s performance obligations are satisfied over time over the life of the contract. The Company’s revenue arrangements consist of a single performance obligation to transfer services. Revenue is recognized over time by measuring the progress toward complete satisfaction of the performance obligation using specific milestones. These milestones within the contract are assigned revenue recognition percentages, based on overall expected cost-plus margin estimates of those milestones compared to the total cost of the contract. Contract revenues are recognized in the proportion that contract costs incurred bear to total estimated costs. This method is used because management considers the input method to be the best available measure of progress on these contracts. Contract costs include all direct material and labor and subcontractor costs and those indirect costs related to contract performance, such as indirect labor, supplies, tools, repairs, and depreciation. General, selling, and administrative costs are charged to expense as incurred. We also record as revenue all amounts billed to customers for shipping and handling costs and record the actual shipping costs as a component of cost of revenues. Reimbursements received from customers for out-of-pocket expenses are recorded as revenues, with related costs recorded as cost of revenues. We present revenues net of any taxes collected from customers and remitted to government authorities. Revenues for the six-month period ended June 30, 2023 in the amount of $843,321 were generated from the sale of the AirSCWO system, $8,000 was generated from the sale of treatability services. Revenues for the six-month period ended June 30, 2022 in the amount of $1,303,759 were generated from the sale of the AirSCWO system. Stock-based Compensation The Company has accounted for stock-based compensation under the provisions of ASC Topic 718 – “Stock Compensation” which requires the use of the fair-value based method to determine compensation for all arrangements under which employees and others receive shares of stock or equity instruments (stock options and common stock purchase warrants). The fair value of each stock option award is estimated on the date of grant using the Black-Scholes valuation model that uses assumptions for expected volatility, expected dividends, expected term, and the risk-free interest rate. Expected volatilities are based on historical volatility of peer companies and other factors estimated over the expected term of the stock options. The expected term of options granted is derived using the “simplified method” which computes expected term as the average of the sum of the vesting term plus the contract term. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant for the period of the expected term. Income Tax Policy The Company accounts for income taxes using the liability method prescribed by ASC 740 - Income Taxes. Under this method, deferred tax assets and liabilities are determined based on the difference between the financial reporting and tax bases of assets and liabilities using enacted tax rates that will be in effect in the year in which the differences are expected to reverse. The Company records a valuation allowance to offset deferred tax assets if, based on the weight of available evidence, it is more-likely-than-not that some portion, or all, of the deferred tax assets will not be realized. The effect on deferred taxes of a change in tax rates is recognized as income or loss in the period that includes the enactment date. Accounting for Uncertainty in Income Taxes The Company follows the provisions of ASC Topic 740-10, “Accounting for Uncertainty in Income Taxes” which clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements and prescribes a recognition threshold and measurement process for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. This topic also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition. There were no uncertain tax positions as of June 30, 2023 and December 31, 2022. Research and Development Costs The Company’s research and development costs are expensed in the period in which they are incurred. Such expenditures amounted to $627,869 and $608,348 for the six months ended June 30, 2023, and 2022, respectively. Earnings (Loss) Per Share Earnings (loss) per share is computed in accordance with ASC Topic 260, “Earnings per Share” Basic weighted-average number of shares of common stock outstanding for the years ended June 30, 2023 and December 31, 2022 include the shares of the Company issued and outstanding during such periods, each on a weighted average basis. The basic weighted average number of shares common stock outstanding excludes common stock equivalent incremental shares, while diluted weighted average number of shares outstanding includes such incremental shares. However, as the Company was in a loss position for all periods presented, basic and diluted weighted average shares outstanding are the same, as the inclusion of the incremental shares would be anti-dilutive. As of June 30, 2023, there were the following potentially dilutive securities that were excluded from diluted net loss per share because their effect would be antidilutive : options for 12,855,467 shares of common stock and 1,235,000 warrants. As of December 31, 2022, there were the following potentially dilutive securities that were excluded from diluted net loss per share because their effect would be antidilutive : options for 12,752,000 shares of common stock and 1,250,000 warrants. Financial Instruments The Company carries cash, accounts receivable, accounts payable and accrued expenses, at historical costs. The respective estimated fair values of these assets and liabilities approximate carrying values / useful lives of equipment and intangible assets due to their current nature. Foreign Currency Translation All assets and liabilities of the Company’s locations whose accounts are denominated in foreign currency are translated into United States dollars at appropriate year-end current exchange rates. All income and expense accounts of those locations are translated at the average exchange rate for each period. The foreign currency translation amounts for the period ended June 30, 2023 and the year ended December 31, 2022 are included in accumulated comprehensive income on the consolidated statement of changes in stockholders’ equity. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect 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 income and expenses during the reporting period. Actual results could differ from those estimates. Significant estimates in the accompanying financial statements include the fair value of equity-based compensation, revenue, fair value of intangible assets, useful lives of intangible assets, capital raise transactions, and valuation allowance against deferred tax assets. Recent Accounting Pronouncements In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments The Company considers the applicability and impact of all recently issued accounting pronouncements. Recent accounting pronouncements not specifically identified in our disclosures are either not applicable to the Company or are not expected to have a material effect on our financial condition or results of operations. |
