Organization and Summary of Significant Accounting Policies

a.

Organization and Nature of Operations: Navidea Biopharmaceuticals, Inc. (“Navidea,” the “Company,” or “we”), a Delaware Corporation (NYSE American: NAVB), is a biopharmaceutical company focused on the development and commercialization of precision immunodiagnostic agents and immunotherapeutics. Navidea is developing multiple precision-targeted products based on our Manocept™ platform to enhance patient care by identifying the sites and pathways of undetected disease and enable better diagnostic accuracy, clinical decision-making and targeted treatment.

Navidea’s Manocept platform is predicated on the ability to specifically target the CD206 mannose receptor expressed on activated macrophages. The Manocept platform serves as the molecular backbone of Tc99m tilmanocept, the first product developed and commercialized by Navidea based on the platform. Other than Tc99m tilmanocept, which the Company has a license to distribute outside of Canada, Mexico and the United States, none of the Company’s drug product candidates have been approved for sale in any market.

In  July 2011, we established a British business unit, Navidea Biopharmaceuticals Limited (“Navidea UK”), to address European and international development and commercialization needs for our technologies, including Tc99m tilmanocept. Navidea owns 100% of the outstanding shares of Navidea UK.

In January 2015, Macrophage Therapeutics, Inc. (“MT”) was formed specifically to explore immuno-therapeutic applications for the Manocept platform. Navidea owns 99.9% of the outstanding shares of MT.

In  June 2020, in anticipation of the United Kingdom’s separation from the European Union (“Brexit”), we established an Irish entity, Navidea Biopharmaceuticals Europe Limited (“Navidea Europe”). Following Brexit, Navidea Europe allows us to continue to develop and commercialize our technologies within the European Union (“EU”) as well as internationally. Navidea owns 100% of the outstanding shares of Navidea Europe.

b.

Principles of Consolidation: Our consolidated financial statements include the accounts of Navidea and our wholly-owned subsidiaries, Navidea Europe and Navidea UK, as well as those of our majority-owned subsidiary, MT. All significant inter-company accounts were eliminated in consolidation.

c.

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.

d.

Revenue Recognition: We currently generate revenue from a grant to support one of our product development initiatives. We generally recognize grant revenue when expenses reimbursable under the grant have been paid and payments under the grant become contractually due.

We also earn revenues related to our licensing and distribution agreements. The consideration we are eligible to receive under our licensing and distribution agreements typically includes upfront payments, reimbursement for research and development (“R&D”) costs, milestone payments, and royalties. Each licensing and distribution agreement is unique and requires separate assessment in accordance with current accounting standards. See Note 3.

e.

Stock-Based Compensation: As of December 31, 2021, we had instruments outstanding under two stock-based compensation plans; the Fourth Amended and Restated 2002 Stock Incentive Plan (the “2002 Plan”) and the Amended and Restated 2014 Stock Incentive Plan (the “2014 Plan”). Currently, under the 2014 Plan, we may grant incentive stock options, nonqualified stock options, and restricted stock awards to full-time employees and directors, and nonqualified stock options and restricted stock awards may be granted to our consultants and agents. Total shares authorized under the 2014 Plan is 1,750,000 shares. Although instruments are still outstanding under the 2002 Plan, the 2002 Plan has expired and no new grants may be made from it. Under both plans, the exercise price of each option is greater than or equal to the closing market price of our Common Stock on the date of the grant.

Stock options granted under the 2002 Plan and the 2014 Plan generally vest on an annual basis over one to four years. Outstanding stock options under the plans, if not exercised, generally expire ten years from their date of grant or up to 90 days following the date of an optionee’s separation from employment with the Company. We issue new shares of our Common Stock upon exercise of stock options.

Stock-based payments to employees and directors, including grants of stock options and restricted stock, are recognized in the statements of operations based on their estimated fair values on the date of grant, subject to an estimated forfeiture rate. The fair value of each option award with time-based vesting provisions is estimated on the date of grant using the Black-Scholes option pricing model. The determination of fair value using the Black-Scholes option pricing model is affected by our stock price as well as assumptions regarding a number of complex and subjective variables, including expected stock price volatility, risk-free interest rate, expected dividends and projected employee stock option behaviors. The fair value of each option award with market-based vesting provisions is estimated on the date of grant using a Monte Carlo simulation. The determination of fair value using a Monte Carlo simulation is affected by our stock price as well as assumptions regarding a number of complex and subjective variables, including expected stock price volatility, risk-free interest rate, expected dividends and projected employee stock option behaviors.

Expected volatilities are based on the Company’s historical volatility, which management believes represents the most accurate basis for estimating expected future volatility under the current circumstances. Navidea uses historical data to estimate forfeiture rates. The expected term of stock options granted is based on the vesting period and the contractual life of the options. The risk-free rate is based on the U.S. Treasury yield in effect at the time of the grant. The assumptions used to calculate the fair value of stock option awards granted during the years ended December 31, 2021 and 2020 are noted in the following table.

The portion of the fair value of stock-based awards that is ultimately expected to vest is recognized as compensation expense over either (1) the requisite service period or (2) the estimated performance period. Restricted stock awards are valued based on the closing stock price on the date of grant and amortized ratably over the estimated life of the award. Restricted stock may vest based on the passage of time, or upon occurrence of a specific event or achievement of goals as defined in the grant agreements. In such cases, we record compensation expense related to grants of restricted stock based on management’s estimates of the probable dates of the vesting events. Stock-based awards that do not vest because the requisite service period is not met prior to termination result in reversal of previously recognized compensation cost. See Note 4.

f.

Research and Development Costs: R&D expenses include both internal R&D activities and external contracted services. Internal R&D activity expenses include salaries, benefits, and stock-based compensation, as well as travel, supplies, and other costs to support our R&D staff. External contracted services include clinical trial activities, manufacturing and control-related activities, and regulatory costs. R&D expenses are charged to operations as incurred. We review and accrue R&D expenses based on services performed and rely upon estimates of those costs applicable to the stage of completion of each project.

g.

Stock Subscriptions and Other Receivables: Stock subscriptions and other receivables are recorded net of an allowance for doubtful accounts. We estimate an allowance for doubtful accounts based on a review and assessment of specific accounts and other receivables and write off accounts against the allowance account when deemed uncollectible. See Note 6.

h.

Inventory: All components of inventory are valued at the lower of cost (first-in, first-out) or net realizable value. We adjust inventory to net realizable value when the net realizable value is lower than the carrying cost of the inventory. Net realizable value is determined based on estimated sales activity and margins. We estimate a reserve for obsolete inventory based on management’s judgment of probable future commercial use, which is based on an analysis of current inventory levels, estimated future sales and production rates, and estimated shelf lives. See Note 7.

i.

Intangible Assets: Intangible assets consist primarily of license agreements, and patent and trademark costs. Intangible assets are stated at cost, less accumulated amortization. License agreements and patent costs are amortized using the straight-line method over the estimated useful lives of the license agreements and patents of approximately 5 to 15 years. Patent application costs are deferred pending the outcome of patent applications. Costs associated with unsuccessful patent applications and abandoned intellectual property are expensed when determined to have no recoverable value. We evaluate the potential alternative uses of all intangible assets, as well as the recoverability of the carrying values of intangible assets, on a recurring basis. During 2021 and 2020, we capitalized patent and trademark costs of $304,000 and $278,000, respectively. During 2021 and 2020, we abandoned patents with previously-capitalized patent costs of $99,000 and $9,000, respectively.

j.

Leases: All of our leases are operating leases and are included in right-of-use lease assets, current lease liabilities and noncurrent lease liabilities on our consolidated balance sheets. These assets and liabilities are recognized at the commencement date based on the present value of remaining lease payments over the lease term using the Company’s incremental borrowing rates or implicit rates, when readily determinable. The discount rates used for each lease were based principally on the Platinum debt, which was secured and outstanding for most of 2018. We used a “build-up” method where the approach was to estimate the risk/credit spread priced into the debt rate and then adjust that for the remaining term of each lease. Additionally, some market research was completed on the Company’s peer group as identified for purposes of compensation analysis. Short-term operating leases which have an initial term of 12 months or less are not recorded on the consolidated balance sheets. Lease expense for operating leases is recognized on a straight-line basis over the lease term. Lease expense is included in selling, general and administrative expenses on our consolidated statements of operations. See Note 11.

k.

Contingent Liabilities: We are subject to legal proceedings and claims that arise in the normal course of business. In accordance with ASC Topic 450, Contingencies, we accrue for contingent liabilities when management determines it is probable that a liability has been incurred and the amount can be reasonably estimated. This determination requires significant judgment by management. As of the date of the filing of this Annual Report on Form 10-K, we are engaged in separate matters of ongoing litigation with Capital Royalty Partners II, L.P. and our former President and Chief Executive Officer, Dr. Michael Goldberg.

In  assessing whether we should accrue a liability in our financial statements as a result of the lawsuits, we considered various factors, including the legal and factual circumstances of the cases, the trial records and post-trial rulings of the applicable courts and appellate courts, the current status of the proceedings, applicable law and the views of legal counsel. We have concluded that a loss from these cases is not probable and reasonably estimable and, therefore, a liability has not been recorded with respect to these cases as of December 31, 2021. While we believe that the ultimate resolution of these matters will not have a material impact on our financial statements, the outcome of litigation is inherently uncertain and the final resolution of these matters may result in expense to us in excess of management's expectations. See Note 12.

l.

Convertible Preferred Stock: The Company evaluated the provisions of the Series C, Series D and Series E Convertible Preferred Stock under Accounting Standards Codification (“ASC”) 480, Distinguishing Liabilities from Equity, ASC 815, Derivatives and Hedging, ASC 470, Debt, and Accounting Series Release (“ASR”) 268, Presentation in Financial Statements of “Redeemable Preferred Stocks.” Based on this evaluation, the Company determined that neither the Series C, Series D nor Series E Preferred Stock is a mandatorily redeemable financial instrument and any obligation to issue a variable number of shares of Common Stock is not unconditional. Accordingly, the Series C, Series D and Series E Preferred Stock should be classified as equity. Neither the embedded conversion option nor the embedded call option meet the criteria to be separated from the Series C, Series D or Series E Preferred stock and thus these features should not be bifurcated and accounted for as derivatives. Additionally, the Series C and Series D Preferred Stock contain a beneficial conversion feature (“BCF”). Prior to the adoption of Accounting Standards Update (“ASU”) No. 2020-06, Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, effective January 1, 2021, the BCF resulted in an increase to additional paid-in capital and a discount on the Series C and Series D Preferred Stock. The discounts on the Series C and Series D Preferred Stock were considered to be fully amortized at the date of issuance because the Series C and Series D Preferred Stock are immediately convertible, resulting in a deemed dividend at the date of issuance for the amount of the BCF. Following adoption of ASU 2020-06, no BCF is recorded in the consolidated financial statements. Finally, the Company determined that the Series D and Series E Preferred Stock does not contain conversion features that could result in the Company being required to redeem a portion of the shares converted, thus the Series D and Series E Preferred Stock should not be classified in mezzanine equity. See Note 13.

m.

Income Taxes: 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 bases, 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. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Due to the uncertainty surrounding the realization of the deferred tax assets in future tax returns, all of the deferred tax assets have been fully offset by a valuation allowance as of December 31, 2021 and 2020.

Current accounting standards include guidance on the accounting for uncertainty in income taxes recognized in the financial statements. Such standards also prescribe a recognition threshold and measurement model for the financial statement recognition of a tax position taken, or expected to be taken, and provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. The Company believes that the ultimate deductibility of all tax positions is highly certain, although there is uncertainty about the timing of such deductibility. As a result, no liability for uncertain tax positions was recorded as of December 31, 2021 or 2020 and we do not expect any significant changes in the next twelve months. Should we need to accrue interest or penalties on uncertain tax positions, we would recognize the interest as interest expense and the penalties as a selling, general and administrative expense. As of December 31, 2021, tax years 2018-2021 remained subject to examination by federal and state tax authorities. See Note 14.

n.

Recently Adopted Accounting Standards: In August 2018, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement. ASU 2018-13 is intended to improve the effectiveness of disclosure requirements on fair value measurements in Topic 820. ASU 2018-13 modifies certain disclosure requirements and is effective for annual and interim reporting periods beginning after December 15, 2019. The adoption of ASU 2018-13 did not have any impact on our consolidated financial statements or our fair value disclosures.

In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. ASU 2019-12 is intended to improve consistent application and simplify the accounting for income taxes. ASU 2019-12 removes certain exceptions to the general principles in Topic 740 and clarifies and amends existing guidance. ASU 2019-12 is effective for annual and interim reporting periods beginning after December 12, 2020, with early adoption permitted. The adoption of ASU 2019-12 did not have a material impact on our consolidated financial statements.

In August 2020, the FASB issued ASU No. 2020-06, Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity. ASU 2020-06 was issued to reduce the complexity associated with accounting for certain financial instruments with characteristics of liabilities and equity. ASU 2020-06 reduces the number of accounting models for convertible debt instruments and convertible preferred stock and improves the disclosures for convertible instruments and related earnings-per-share (“EPS”) guidance. ASU 2020-06 also amends the guidance for the derivatives scope exception for contracts in an entity’s own equity and improves and amends the related EPS guidance. ASU 2020-06 is effective for public business entities except smaller reporting companies for annual and interim reporting periods beginning after December 15, 2021, and for annual and interim reporting periods beginning after December 15, 2023 for all other entities. Early adoption is permitted, but the guidance must be adopted as of the beginning of a fiscal year. We adopted ASU 2020-06 effective January 1, 2021 using the modified retrospective method. Prior to the adoption of ASU 2020-06, the BCF contained in the Series C and Series C Preferred Stock resulted in an increase to additional paid-in capital and a discount on the Series C and Series D Preferred Stock. The discounts on the Series C and Series D Preferred Stock were considered to be fully amortized at the date of issuance because the Series C and Series D Preferred Stock are immediately convertible, resulting in a deemed dividend at the date of issuance for the amount of the BCF. Following adoption of ASU 2020-06, no BCF is recorded in the consolidated financial statements. The adoption of ASU 2020-06 did not result in a cumulative effect adjustment to retained earnings.

o.

Recently Issued Accounting Standards: In May 2021, the FASB Issued ASU No. 2021-04, Issuer’s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options. ASU 2021-04 was issued to clarify and reduce diversity in an issuer’s accounting for modifications or exchange of freestanding equity-classified written call options (for example, warrants) that remain equity-classified after modification or exchange. ASU 2021-04 requires that an entity treat a modification or exchange of a freestanding equity-classified written call option that remains equity-classified after modification or exchange be treated as an exchange of the original instrument for a new instrument. ASU 2021-04 also clarifies how an entity should measure and recognize the effect of a modification or exchange of a freestanding equity-classified written call option that remains equity-classified after modification or exchange. ASU 2021-04 is effective for all entities for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years, and should be implemented prospectively to modifications or exchanges occurring on or after the effective date of the amendments. Early adoption is permitted, including in an interim period. We do not expect the adoption of ASU 2021-04 to have a material impact on our consolidated financial statements.

In November 2021, the FASB issued ASU No. 2021-10, Disclosures by Business Entities about Government Assistance. ASU 2021-10 was issued to increase the transparency of government assistance. ASU 2021-10 requires that entities make certain annual disclosures about transactions with a government that are accounted for by applying a grant or contribution accounting model by analogy. The required disclosures include: (1) information about the nature of the transactions and the related accounting policy used to account for the transactions; (2) the line items on the balance sheet and income statement that are affected by the transactions, and the amounts applicable to each financial statement line item; and (3) significant terms and conditions of the transactions, including commitments and contingencies. The amendments in ASU 2021-10 are effective for all entities within their scope for financial statements issued for annual periods beginning after December 15, 2021. Early application of the amendments is permitted. An entity should apply the amendments in ASU 2021-10 either (1) prospectively to all transactions within the scope of the amendments that are reflected in financial statements at the date of initial application and new transactions that are entered into after the date of initial application or (2) retrospectively to those transactions. We do not expect the adoption of ASU 2021-10 to have an impact on our consolidated financial statements, however we do expect to make the additional disclosures required by the update.
