Summary of Significant Accounting Policies | 2. Summary of Significant Accounting Policies Principles of Consolidation The accompanying consolidated financial statements of the Company have been prepared in accordance with United States generally accepted accounting principles (“GAAP”) and include the financial statements of Bone Biologics Corporation and its wholly-owned subsidiary, Bone Biologics Inc. Intercompany balances and transactions have been eliminated in consolidation. Segment Information The Company operates and reports in one segment, which focuses on bone regeneration in spinal fusion using the recombinant human protein known as NELL-1. The Company’s operating segment is reported in a manner consistent with the internal reporting provided to the Chief Operating Decision Maker, which is the Company’s Chief Executive Officer and President. Use of Estimates The preparation of the accompanying consolidated financial statements in conformity with 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 consolidated financial statements and reported amounts of expenses during the reporting period. Significant estimates include the assumptions used in the accrual for potential liabilities, the valuation of the warrant liability, the valuation of debt and equity instruments, the valuation of stock options and warrants issued for services, and deferred tax valuation allowances. Actual results could differ from those estimates. Inflation Macroeconomic factors such as inflation, rising interest rates, governmental responses there to and possible recession caused thereby also add significant uncertainty to the Company’s operations and possible effects to the amount and type of financing available to the Company in the future. Cash Cash primarily consists of bank demand deposits maintained by a major financial institution. The Company’s policy is to maintain its cash balances with financial institutions with high credit ratings and in accounts insured by the Federal Deposit Insurance Corporation (the “FDIC”) and/or by the Securities Investor Protection Corporation (the “SIPC”). The Company may periodically have cash balances in financial institutions in excess of the FDIC and SIPC insurance limits of $ 250,000 500,000 Fair Value of Financial Instruments Accounting standards require certain assets and liabilities be reported at fair value in the financial statements and provide a framework for establishing that fair value. The Company defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The fair value hierarchy is based on three levels of inputs that may be used to measure fair value, of which the first two are considered observable and the last is considered unobservable: Level 1: Quoted prices in active markets for identical assets or liabilities. Level 2: Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; 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 assumptions: Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities including liabilities resulting from embedded derivatives associated with certain warrants to purchase common stock. The fair value of financial instruments measured on a recurring basis was as follows as of December 31, 2023: Schedule of Fair Value Liabilities Measured on Recurring Basic Description Total Level 1 Level 2 Level 3 As of Description Total Level 1 Level 2 Level 3 Liabilities: Warrant liability $ 55,751 — — $ 55,751 Total liabilities at fair value $ 55,751 — — $ 55,751 The following table provides a roll-forward of the warrant liability measured at fair value on a recurring basis using unobservable level 3 inputs for the years ended December 31, 2023 as follows: Schedule of Warrant Liability Measured Fair Value on a Recurring Basic Using Unobservable 2023 Warrant liability Balance as of beginning of period – December 31, 2022 $ 1,659,468 Extinguishment of warrant liability upon exercise of warrants (711,024 ) Change in fair value (892,693 ) Balance as of end of period – December 31, 2023 $ 55,751 The Company believes the carrying amount of certain financial instruments, including cash and accounts payable approximate their values based on their short-term nature and are excluded from the fair value tables above. Prepaid Insurance Prepaid insurance represents the premiums paid for directors and officers insurance coverage and for general liability insurance coverage in excess of the amortization of the total policy premium charged to operations at each balance sheet date. Such amount is determined by amortizing the total policy premium charged on a straight-line basis over the respective policy period. As the policy premiums incurred are generally amortizable over the ensuing twelve-month period, they are recorded as a current asset in the Company’s consolidated balance sheet at each reporting date and appropriately amortized to the Company’s consolidated statement of operations for each reporting period. Prepaid Expenses At December 31, 2023, prepaid expenses consisted of prepaid insurance and prepaid services. Prepaid expenses are amounts paid to secure the use of assets or the receipt of services at a future date or continuously over one or more future periods. When the prepaid expenses are eventually consumed, they are charged to expense. The Company had $ 711,194 956,925 Research and Development Costs Research and development costs include, but are not limited to, payroll and other personnel expenses, consultants, expenses incurred under agreements with contract research and manufacturing organizations and animal clinical investigative sites and the cost to manufacture clinical trial materials. Research and development costs are generally charged to operations ratably over the life of the underlying contracts, unless the achievement of milestones, the completion of contracted work, the termination of an agreement, or other information indicates that a different expensing schedule is more appropriate. However, payments for research and development costs that are contractually defined as non-refundable are charged to operations as incurred. Payments made pursuant to contracts are initially recorded as advances on research and development contract services in the Company’s consolidated balance sheet and are then charged to research and development costs in the Company’s consolidated statement of operations as those contract services are performed. Expenses incurred under contracts in excess of amounts advanced are recorded as research and development contract liabilities in the Company’s consolidated balance sheet, with a corresponding charge to research and development costs in the Company’s consolidated statement of operations. The Company reviews the status of its various clinical trial and research and development contracts on a quarterly basis. Research and development costs, including costs associated with clinical trials involving the Company’s lead product candidate, are summarized below based on the respective geographical regions where such costs are incurred. Summary of Geographical Regions 2023 2022 Years Ended December 31, 2023 2022 United States $ 6,693,377 $ 1,579,298 Australia 214,447 - Total $ 6,907,824 $ 1,579,298 Patents and Licenses Effective April 9, 2019, the Company entered into an Amended and Restated Exclusive License Agreement dated as of March 21, 2019 and amended through three sets of amendments (as so amended the “Amended License Agreement”) with the UCLA TDG. The Amended License Agreement amends and restates the Amended and Restated Exclusive License Agreement, dated as of June 19, 2017 (the “2017 Agreement”). The 2017 Agreement amended and restated the Exclusive License Agreement, effective March 15, 2006, between the Company and UCLA TDG, as amended by ten amendments. See Note 7 for commitments related to the Exclusive License Agreement. Patent expenses include costs to acquire the license of NELL-1, which was de minimis, and costs to file patent applications related to NELL-1. The Company expenses the costs incurred to file patent applications, all costs related to abandoned patent applications and maintenance costs, and these costs are included in general and administrative expenses. Costs associated with licenses acquired to be able to use products from third parties prior to receipt of regulatory approval to market the related products are also expensed. The Company’s licensed technologies may have alternative future uses in that they are enabling (or platform) technologies that can be the basis for multiple products that would each target a specific indication. Costs of acquisition of licenses are expensed. Stock Based Compensation ASC 718, Compensation – Stock Compensation Income Taxes The Company uses an asset and liability approach for accounting and reporting for income taxes that allows recognition and measurement of deferred tax assets based upon the likelihood of realization of tax benefits in future years. Under the asset and liability approach, deferred taxes are provided for the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. A valuation allowance is provided for deferred tax assets if it is more likely than not these items will either expire before the Company is able to realize their benefits, or that future deductibility is uncertain. The Company’s policy is to recognize interest and/or penalties related to income tax matters in income tax expense. No such amounts were accrued as of December 31, 2023 and 2022. Loss per Common Share Basic loss per share is computed by dividing the loss available to common shareholders by the weighted-average number of common shares outstanding during the period. Diluted loss per share is computed similar to basic loss per share except that the denominator is increased to include the number of additional common shares that would have been outstanding if the potential common shares had been issued and if the additional common shares were dilutive. Diluted loss per common share reflects the potential dilution that could occur if options and warrants were to be exercised or converted or otherwise resulted in the issuance of common stock that then shared in the earnings of the entity. Since the effects of outstanding options, warrants, and the conversion of convertible debt are anti-dilutive for the years ended December 31, 2023 and 2022, shares of common stock underlying these instruments have been excluded from the computation of loss per common share. The following sets forth the number of shares of common stock underlying outstanding options and warrants as of December 31, 2023 and 2022: Schedule of Anti Dilutive Securities Excluded from Computation of Earnings Per Share 2023 2022 December 31, 2023 2022 Warrants 197,844 57,692 Stock options 34,310 1,910 Anti dilutive securities 232,154 59,602 Reclassifications Certain prior year balances have been reclassified to conform with the current year presentation.
