Summary of Significant Accounting Policies | NOTE 3 – Summary of Significant Accounting Policies Management’s 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 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 revenues and expenses during the reporting period. Actual results could differ from those estimates. Cash and Cash Equivalents The Company considers all highly liquid investments with an original contractual maturity on date of purchase of less than or equal to three months to be classified and presented as cash equivalents on the Balance Sheets. Cash equivalents are stated at cost, which approximates fair value. The Company’s cash and cash equivalents may include demand deposit accounts with large financial institutions, institutional money market funds, U.S. Treasury securities, and corporate notes and bonds. The Company monitors the creditworthiness of the financial institutions, institutional money market funds, and corporations in which the Company invests its surplus funds. The Company has experienced no credit losses from its cash and cash equivalent investments. Short Term Investment The Company invests its excess cash in United States (“U.S.”) Treasury securities and highly rated corporate securities. The Company intends and has the ability to hold these investments to maturity. Securities with original maturity dates of more than three months are reported as held-to-maturity investments and are recorded at amortized cost, which approximates fair value due to the negligible risk of changes in value due to interest rates. All investments held as of December 31, 2022 and September 30, 2022 had contractual maturities of less than one year. The amortized cost and estimated fair values of the Company’s investments as of December 31, 2022 and September 30, 2022 are as follows: December 31, 2022 Unrealized Unrealized Amortized Holding Holding Fair Short-term: U.S. treasury and corporate notes $ 2,975,194 $ — $ 769 $ 2,974,425 Total $ 2,975,194 $ — $ 769 $ 2,974,425 September 30, 2022 Unrealized Unrealized Amortized Holding Holding Fair Short-term: U.S. treasury and corporate notes $ 2,981,010 $ — $ 2,870 $ 2,978,140 Total $ 2,981,010 $ — $ 2,870 $ 2,978,140 Revenue Recognition The Company entered into a development and distribution agreement which has current and future revenue recognition implications. See “Note 7 – Zimmer Development Agreement.” In determining the appropriate amount of revenue to be recognized as it fulfills its obligations under its agreements, the Company performs the following steps: (i) identification of the promised goods or services in the contract; (ii) determination of whether the promised goods or services are performance obligations, including whether they are distinct in the context of the contract; (iii) measurement of the transaction price, including the constraint on variable consideration; (iv) allocation of the transaction price to the performance obligations based on estimated selling prices; and (v) recognition of revenue when (or as) the Company satisfies each performance obligation. Product Revenue Revenues from product sales are recognized when control of the promised goods or services is transferred to the Company’s customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. At the inception of each customer contract, performance obligations are identified and the total transaction price is allocated to the performance obligations. The Company commenced commercial sales of cEEG strip/grid and electrode cable assembly products in the first quarter of fiscal year 2021. Cost of Product Revenue Cost of product revenue consists of the manufacturing and materials costs incurred by the Company’s third-party contract manufacturer in connection with the Company’s strip and grid cortical electrodes (the “Strip/Grid Products”) and outside supplier materials costs in connection with the . In addition, cost of product revenue includes royalty fees incurred in connection with the Company’s license agreements. Collaborations Revenue A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is the unit of account in Account Standards Codification (“ASC”) Topic 606. (“ASC 606”). Performance obligations may include license rights, development services, and services associated with regulatory submission and approval processes. Significant management judgment is required to determine the level of effort required under an arrangement and the period over which the Company expects to complete its performance obligations under the arrangement. If the Company cannot reasonably estimate when its performance obligations are either completed or become inconsequential, then revenue recognition is deferred until the Company can reasonably make such estimates. Revenue is then recognized over the remaining estimated period of performance using the cumulative catch-up method. As part of the accounting for collaboration arrangements, the Company must develop assumptions that require judgment to determine the stand-alone selling price of each performance obligation identified in the contract. The Company uses key assumptions to determine the stand-alone selling price, which may include forecasted revenues, development timelines, reimbursement rates for personnel costs, discount rates and probabilities of technical and regulatory success. The Company allocates the total transaction price to each performance obligation based on the estimated relative standalone selling prices of the promised goods or service underlying each performance obligation. Licenses of intellectual property Milestone payments Royalties Fair Value of Financial Instruments The Company’s accounting for fair value measurements of assets and liabilities that are recognized or disclosed at fair value in the financial statements on a recurring or nonrecurring basis adheres to the Financial Accounting Standards Board (“FASB”) fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to measurements involving significant unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are as follows: ● Level 1 Inputs: Unadjusted quoted prices in active markets for identical assets or liabilities accessible to the Company at the measurement date. ● Level 2 Inputs: Other than quoted prices included in Level 1 inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability. ● Level 3 Inputs: Unobservable inputs for the asset or liability used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at the measurement date. As of December 31, 2022 and September 30, 2022, the fair values of cash, cash equivalents, short-term investments, accounts receivable, inventory, prepaid and other assets, accounts payable and accrued expenses approximated their carrying values because of the short-term nature of these assets or liabilities. There were no transfers between fair value hierarchy levels during the three months ended December 31, 2022 and 2021. Intellectual Property The Company has entered into two licensing agreements with major research institutions, which allow for access to certain patented technology and know-how. Payments under those agreements are capitalized and amortized to general and administrative expense over the expected useful life of the acquired technology. Property and Equipment Property and equipment is recorded at cost and reduced by accumulated depreciation. Depreciation expense is recognized over the estimated useful lives of the assets using the straight-line method. The estimated useful life for equipment and furniture ranges from three to seven years and three years for software. Tangible assets acquired for research and development activities and that have alternative use are capitalized over the useful life of the acquired asset. Estimated useful lives are periodically reviewed, and, when appropriate, changes are made prospectively. Software purchased for internal use consists primarily of amounts paid for perpetual licenses to third-party software providers and installation costs. When certain events or changes in operating conditions occur, asset lives may be adjusted and an impairment assessment may be performed on the recoverability of the carrying amounts. Maintenance and repairs are charged directly to expense as incurred. Impairment of Long-Lived Assets The Company evaluates its long-lived assets, which consist of licensed intellectual property, property and equipment and right of use assets for impairment whenever events or changes in circumstances indicate that the carrying value of these assets may not be recoverable. The Company assesses the recoverability of long-lived assets by determining whether or not the carrying value of such assets will be recovered through undiscounted expected future cash flows. If the asset is considered to be impaired, the amount of any impairment is measured as the difference between the carrying value and the fair value of the impaired asset. Allowances for Doubtful Accounts The Company records a provision for doubtful accounts, when appropriate, based on historical experience and a detailed assessment of the collectability of its accounts receivable. In estimating the allowance for doubtful accounts, the Company considers, among other factors, the aging of the accounts receivable, its historical write-offs, the credit worthiness of each customer, and general economic conditions. Account balances are charged off against the allowance when the Company believes that it is probable that the receivable will not be recovered. Actual write-offs may be in excess of the Company’s estimated allowance. Inventories Inventories are stated at the lower of cost (using the first-in, first-out “FIFO” method) or net realizable value. The Company calculates inventory valuation adjustments for excess and obsolete inventory, when appropriate, based on current inventory levels, movement, expected useful lives, and estimated future demand of the products and spare parts. The Company’s inventory is currently comprised of cEEG strip/grid and electrode cable assembly work-in-process and finished good product. The Strip/Grid Products are produced by a third-party contract manufacturer and the Electrode Cable Assembly Products are obtained from outside suppliers. Research and Development Costs Research and development costs are charged to expense as incurred. Research and development expenses may include costs incurred in performing research and development activities, including clinical trial costs, manufacturing costs for both clinical and pre-clinical materials as well as other contracted services, license fees, and other external costs. Non-refundable advance payments for goods and services that will be used in future research and development activities are expensed when the activity is performed or when the goods have been received, rather than when payment is made, in accordance with ASC 730, Research and Development Selling, General and Administrative Selling, general and administrative expenses consist primarily of personnel-related costs including stock-based compensation for personnel in functions not directly associated with research and development activities. Other significant costs include legal and litigation costs relating to corporate matters, intellectual property costs, professional fees for consultants assisting with regulatory, clinical, product development, financial matters, and sales and marketing in connection with the commercial sales of the Company’s products. Stock-Based Compensation The Company accounts for stock-based compensation in accordance with the provisions of ASC 718, Compensation — Stock Compensation Income Taxes For the Company, income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax base and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Deferred tax assets are reduced by a valuation allowance if it is more likely than not that some portion or all of the deferred tax asset will not be realized. Net Loss Per Share For the Company, basic loss per share of common stock is computed by dividing net loss by the weighted average number of shares of common stock outstanding during the period. Diluted earnings or loss per share of common stock is computed similarly to basic earnings or loss per share except the weighted average shares outstanding are increased to include additional shares from the assumed exercise of any common stock equivalents, if dilutive. The Company’s warrants, stock options and restricted stock units are considered common stock equivalents for this purpose. Diluted earnings is computed utilizing the treasury method for the warrants, stock options and restricted stock units. No incremental common stock equivalents were included in calculating diluted loss per share because such inclusion would be anti-dilutive given the net loss reported for both the three months ended December 31, 2022 and 2021. The following potential common shares were not considered in the computation of diluted net loss per share as their effect would have been anti-dilutive for the three months ended December 31: 2022 2021 Warrants 7,103,344 6,753,444 Stock options 1,313,646 1,111,226 Restricted stock units 392,500 6,888 Unissued vested restricted stock units 7,322 — Recent Accounting Pronouncements In June 2016, the FASB issued Accounting Standards Update (“ASU”) 2016-13, “ Financial Instruments – Credit Losses” In August 2020, 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): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity |
