Summary of Significant Accounting Policies | Summary of Significant Accounting Policies Basis of Presentation The Company’s consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) as determined by the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) and pursuant to the regulations of the U.S. Securities and Exchange Commission (“SEC”). For all periods presented, net loss equals comprehensive loss. Reverse Recapitalization The Business Combination was accounted for as a reverse recapitalization and Spartan was treated as the “acquired” company for accounting purposes. The Business Combination was accounted as the equivalent of Legacy Fisker issuing stock for the net assets of Spartan, accompanied by a recapitalization. Accordingly, all historical financial information presented in these consolidated financial statements represents the accounts of Legacy Fisker and its wholly owned subsidiaries “as if” Legacy Fisker is the predecessor to the Company. The shares and net loss per common share, prior to the Business Combination, have been adjusted as shares reflecting the exchange ratio established in the Business Combination. Going Concern, Liquidity and Capital Resources The Company evaluated whether there are any conditions and events, considered in the aggregate, that raise substantial doubt about its ability to continue as a going concern over the next twelve months from the date of filing this report. As of December 31, 2022, the Company had approximately $736.5 million in cash and cash equivalents, which is unrestricted and available for Fisker's general use. The Company believes that substantial doubt about its ability to continue as a going concern does not exist as its cash on hand will be sufficient to meet its working capital and capital expenditure requirements for a period of at least twelve months from the date of the filing of this Form 10-K. Since inception, the Company has yet to generate significant revenue from its core business operations and has incurred significant accumulated losses of approximately $1.2 billion. The Company expects to continue to incur significant operating losses for the foreseeable future. The Company expects its capital expenditures and working capital requirements to increase substantially in 2023 and beyond, as it progresses toward serial production of the Fisker Ocean EV model, develop its customer support and marketing infrastructure and expand its research and development efforts. The Company may, however, need additional cash resources, including proceeds of up to $156.5 mill ion from the sale of Class A common stock under its at-the-market equity program, to fund its operations until it commences serial production levels of the Fisker Ocean and achieves a level of production and sales that provide for operating profitability. To the extent that Fisker’s current resources are insufficient to satisfy its cash requirements, the Company may need to seek additional equity or debt financing and there can be no assurance that the Company will be successful in its efforts. If the financing is not available, or if the terms of financing are less desirable than the Company expects, the Company may be forced to decrease its planned level of investment in product development or scale back its operations, including production of the Fisker Ocean, which could have an adverse impact on its business and financial prospects. Supplier Risk The Company continued nomination of suppliers with an accelerated phase during the year for engineering, development, testing, tooling and production of components for serial production of its vehicles, which will be assembled in Austria. As of December 31, 2022, these supplier contracts do not represent unconditional purchase obligations with take-or-pay or specified minimum quantities provisions with the exception of an agreement securing battery capacity for the Fisker Ocean SUV. Under the terms of the agreement, the battery supplier will deliver two different battery solutions for the Fisker Ocean SUV, with an initial battery capacity of over 5 gigawatt-hours annually, from 2023 through 2025. Use of Estimates The preparation of the consolidated financial statements in conformity with GAAP required management to make estimates and assumptions that affect the reported amounts of assets and liabilities in the consolidated financial statements and accompanying notes. The Company bases these estimates on historical experience and on various other assumptions that it believes are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying amounts of assets and liabilities that are not readily apparent from other sources. Actual results may differ materially from these estimates. Principles of Consolidation The consolidated financial statements include the accounts of Fisker Inc. and its wholly owned subsidiaries. All inter-company transactions and balances have been eliminated in consolidation. Cash and Cash Equivalents The Company considers all highly liquid investments purchased with original maturities of three months or less at acquisition to be cash equivalents. Cash and cash equivalents include cash held in banks and money market mutual funds, which is unrestricted and available for Fisker's general use. Concentrations of Credit Risk and Off-balance Sheet Risk Cash and cash equivalents are financial instruments that are potentially subject to concentrations of credit risk. The Company’s cash and cash equivalents are deposited in accounts at large financial institutions, and amounts may exceed federally insured limits. The Company believes it is not exposed to significant credit risk due to the financial strength of the depository institutions in which the cash and cash equivalents are held. The Company has no financial instruments with off-balance sheet risk of loss. Fair Value Measurements The Company follows the accounting guidance in ASC 820, Fair Value Measurement , for its fair value measurements of financial assets and liabilities measured at fair value on a recurring basis. Fair value is defined as an exit price, representing the amount 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 a liability. The accounting guidance requires fair value measurements be classified and disclosed in one of the following three categories: Level 1: Quoted prices in active markets for identical assets or liabilities. Level 2: Observable inputs other than Level 1 prices, for similar assets or liabilities that are directly or indirectly observable in the marketplace. Level 3: Unobservable inputs which are supported by little or no market activity and that are financial instruments whose values are determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant judgment or estimation. The fair value hierarchy also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Assets and liabilities measured at fair value are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. Long-Lived Assets Property and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization is computed using the straight-line method over the estimated useful lives of the related assets as follows: Useful Life (in years) Tooling 3-8 Machinery and equipment 5-15 Furniture and fixtures 5-10 IT hardware and software 3-10 Leasehold improvements Shorter of their estimated life or remaining lease term Construction in progress is comprised primarily of costs incurred to construct serial production tooling located at affiliates of Magna and our suppliers. Leasehold improvements are amortized on a straight-line basis over the shorter of their estimated useful lives or the term of the related lease. Upon retirement or sale, the cost and related accumulated depreciation are removed from the balance sheet and the resulting gain or loss is reflected in operations. Maintenance and repair expenditures are expensed as incurred, while major improvements that increase functionality of the asset are capitalized and depreciated ratably to expense over the identified useful life. Long-lived assets, including intangible assets subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If circumstances require a long-lived asset to be tested for possible impairment, the Company first compares undiscounted cash flows expected to be generated by that asset group to its carrying amount. The Company assesses impairment for asset groups, which represent a combination of assets that produce distinguishable cash flows. If the carrying amount of the asset group is not recoverable on an undiscounted cash flow basis, an impairment is recognized to the extent that the carrying amount exceeds its fair value. Fair value is determined through various valuation techniques, including discounted cash flow models, quoted market values, and third-party independent appraisals, as considered necessary. The Company has not recorded any impairment charges during the periods presented. Leases The Company classifies arrangements meeting the definition of a lease as operating or financing leases, and leases are recorded on the consolidated balance sheet as both a right-of-use asset and lease liability, calculated by discounting fixed lease payments over the lease term at the rate implicit in the lease or the Company’s incremental borrowing rate. Lease liabilities are increased by interest and reduced by payments each period, and the right of use asset is amortized over the lease term. For operating leases, interest on the lease liability and the amortization of the right-of-use asset result in straight-line rent expense over the lease term. For finance leases, interest on the lease liability and the amortization of the right-of-use asset results in front-loaded expense over the lease term. Variable lease expenses are recorded when incurred. In calculating the right-of-use asset and lease liability, the Company elects to combine lease and non-lease components for all classes of assets. The Company excludes short-term leases having initial terms of 12 months or less from the new guidance as an accounting policy election, and instead recognizes rent expense on a straight-line basis over the lease term. Current portion of the Company’s lease liability is based on lease payments due within twelve months of the balance sheet date. Variable lease payments are included in lease payments when the contingency upon which the payment is dependent is resolved. Debt Issuance Costs Direct and incremental costs, including amounts paid to initial purchasers of the Company’s convertible notes, are directly attributed to efforts to obtain debt financing are debt issuance costs. Upon issuance of debt, the carrying value is the principal amount of debt reduced by any debt issuance costs. Debt issuance costs are attributed to interest expense and accreted over the expected term of the debt using the effective interest rate method. Derivative Financial Instruments The Company does not use derivative instruments to hedge exposures to interest rate, market, or foreign currency risks. The Company evaluates all of its financial instruments, including notes payable, to determine if such instruments are derivatives or contain features that qualify as embedded derivatives. The Company applies significant judgment to identify and evaluate complex terms and conditions in its contracts and agreements to determine whether embedded derivatives exist. Embedded derivatives must be separately measured from the host contract if all the requirements for bifurcation are met. The assessment of the conditions surrounding the bifurcation of embedded derivatives depends on the nature of the host contract. Bifurcated embedded derivatives are recognized at fair value, with changes in fair value recognized in the statement of operations each period. Bifurcated embedded derivatives are classified with the related host contract in the Company’s balance sheet. The Company enters into contracts that meet the definitions of a freestanding instrument, such as capped call options with equity-linked features, and a derivative. A freestanding instrument that is a derivative is evaluated by the Company to determine if it qualifies for an exception to derivative accounting. The Company determines whether the equity-linked feature is indexed to the Company's Class A common stock and whether the settlement provision in the contract is consistent with a fixed-for-fixed equity instrument. To qualify for classification in stockholder's equity, the Company evaluates whether the contract requires physical settlement, net share settlement, or a combination thereof and, when the Company has a choice of net cash settlement or settlement in the Company's shares, additional criteria are evaluated to determine whether equity classification is appropriate. Refer to Note 11 for additional information regarding the accounting for the convertible senior notes and capped call options. From July 2019 to December 2019, the Company entered into note agreements that were determined to have embedded derivative instruments in the form of a contingent put option. The notes are recognized at the value of proceeds received after allocating issuance proceeds to the separable instruments issued with the notes and to the bifurcated contingent put option. The notes are subsequently measured at amortized cost using the effective interest method to accrete interest over their term to bring the notes’ initial carrying value to their principal balance at maturity. The bifurcated put option is initially measured at fair value which is included in the Bridge notes payable balance on the Consolidated Balance Sheets and subsequently measured at fair value with changes in fair value recognized as a component of Other income (expense) in the Consolidated Statements of Operations (see Note 3). The Company accounts for its public and private warrants as a derivative liability initially measured at its fair values and remeasured in the consolidated statements of operations at the end of each reporting period. When the warrants are exercised, the corresponding derivative liability is de-recognized at the underlying fair value of the Class A common stock that is issued to the warrant holder less any cash paid in accordance with the warrant agreement. Upon either cash or cashless exercise, the de-recognized derivative liability results in an increase in additional paid in capital equal to the difference between the fair value of the underlying Class A common stock and its par value. A cashless exercise results in the warrant holder surrendering Class A common stock equal to the stated warrant exercise price based on the contractual terms in the warrant agreement that govern the cashless conversion. Segments Operating segments are defined as components of an entity for which separate financial information is available and that is regularly reviewed by the Chief Operating Decision Maker (“CODM”) in deciding how to allocate resources to an individual segment and in assessing performance. The Company’s CODM is its Chief Executive Officer. The Company has determined that it operates in one operating segment and one reportable segment, as the CODM reviews financial information presented on a consolidated basis for purposes of making operating decisions, allocating resources, and evaluating financial performance. Revenue Recognition The Company recognizes revenue from contracts with customers in accordance with ASC 606, Revenue from Contracts with Customers (“ASC 606”). The core principle of ASC 606 is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. A good or service is transferred to a customer when, or as the customer obtains control of that good or service. The following five steps are applied to achieve that core principle: • Step 1: Identify the contract with the customer • Step 2: Identify the performance obligation(s) in the contract • Step 3: Determine the transaction price • Step 4: Allocate the transaction price to the performance obligation(s) in the contract • Step 5: Recognize revenue when or as the company satisfies a performance obligation The Company’s customers may reserve a Fisker vehicle by making a deposit, which is refundable, and in certain instances, subject to a 10% administration and process fee in the event of cancellation. In the third quarter of 2022, the Company began accepting order deposits of $5,000 USD or equivalent currency for Fisker Ocean Ones, a limited-edition trim level of the Fisker Ocean. The Company also converted customer deposits for reservation holders who previously made a deposit for an Extreme, Ultra or Sport Ocean prior to August 16, 2022, the enactment date of the Inflation Reduction Act of 2022 (the "Inflation Reduction Act"). Order deposits will be applied to the sales price of the vehicle and recognized as revenue when the vehicle is sold and delivered to the customer. Order Deposits are recognized contract liabilities and not included in customer deposits. The Company has yet to deliver and recognize revenue related to the delivery of a vehicle. Certain holders of the Company’s bridge notes were issued option agreements providing the holder with a non-binding right to receive a base model Fisker Ocean SUV within the first twelve months of production, subject to the terms and conditions. The proceeds received from these holders were allocated to the bridge notes and option agreements on a relative fair value basis, resulting in an initial discount to the bridge notes. Foreign Currency Remeasurement and Transactions The functional currency of the Company’s U.K., German, Indian and Austrian subsidiaries is the U.S. Dollar. For these subsidiaries, monetary assets and liabilities denominated in non U.S. currencies are re-measured to U.S. Dollars using current exchange rates in effect at the balance sheet date. Non-monetary assets and liabilities denominated in non-U.S. currencies are maintained at historical U.S. Dollar exchange rates. Expenses are re-measured at average U.S. Dollar monthly rates. Foreign currency transaction gains and losses are a result of the effect of exchange rate changes on transactions denominated in currencies other than the functional currency. Transaction gains and losses are immaterial for all periods presented. In April and July 2022, the Company purchased 130.1 million Euros for 140.0 million U.S. dollars, a currency exchange rate of 1 U.S. dollar for 1.076 Euro and 50.0 million Euros for 50.9 million U.S. dollars, a currency exchange rate of 1 U.S. dollar for 1.018 Euro, which are designed to provide an economic hedge against future foreign currency exposures. Stock-based Compensation The Company expenses stock-based compensation over the requisite service period based on the estimated grant-date fair value of the awards. The Company accounts for forfeitures as they occur. The Company recognizes non-employee compensation costs over the requisite service period based on a measurement of fair value for each stock award. The grant date for an option or stock award is established when the grantee has a mutual understanding of the key terms and conditions of the option or award, the award is authorized, including all the necessary approvals unless approval is essentially a formality or perfunctory, and the grantee begins to benefit from, or be adversely affected by, underlying changes in the price of the Company’s Class A common shares. An award or option is authorized on the date that all approval requirements are completed (e.g., action by the compensation committee approving the award and the number of options, restricted shares or other equity instruments to be issued to individual employees). From inception through December 31, 2022, the Company has primarily granted service and performance based awards. Stock-based compensation expense is recognized for awards with graded-vesting schedules are recognized on a straight-line basis over the requisite service period for each vesting tranche. The Company estimates the fair value of stock option grants using the Black-Scholes option pricing model, and the assumptions used in calculating the fair value of stock-based awards represent management’s best estimates and involve inherent uncertainties and the application of management’s judgment. For stock-based awards with vesting subject to performance conditions, stock-based compensation expense is recognized over the requisite service period when the performance conditions becomes probable of achievement . All stock-based compensation expense are recorded in selling, general and administrative or research and development costs in the statements of operations based upon the underlying individual’s role at the Company except for the capitalization of costs associated with the Magna wa rrants (see Note 13). Research and Development Costs Research and development costs are expensed as incurred. Research and development expenses consist primarily of payroll, benefits and stock-based compensation of those employees engaged in research, design and development activities, costs related to design and prototype tools, prototype development work, and supplies and services. Advertising Expense All advertising costs are expensed as incurred. For the years ended December 31, 2022, 2021 and 2020, advertising expense w as $9.3 million , $6.3 million, and $0.8 million, respectively. Income Taxes Income taxes are recorded in accordance with ASC 740, Income Taxes (“ASC 740”), which provides for deferred taxes using an asset and liability approach. The Company recognizes deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the consolidated financial statements or tax returns. Deferred tax assets and liabilities are determined based on the difference between the consolidated financial statement and tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. Valuation allowances are provided, if based upon the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. The Company accounts for uncertain tax positions in accordance with the provisions of ASC 740. When uncertain tax positions exist, the Company recognizes the tax benefit of tax positions to the extent that the benefit would more likely than not be realized assuming examination by the taxing authority. The determination as to whether the tax benefit will more likely than not be realized is based upon the technical merits of the tax position as well as consideration of the available facts and circumstances. The Company recognizes any interest and penalties accrued related to unrecognized tax benefits as income tax expense. Net Loss per Share of Common Stock Basic net loss per share of common stock is calculated using the two-class method under which earnings are allocated to both common shares and participating securities. Undistributed net losses are allocated entirely to common shareholders since the participating security has no contractual obligation to share in the losses. Basic net loss per share is calculated by dividing the net loss attributable to common shares by the weighted-average number of shares of common stock outstanding for the period. The diluted net loss per share of common stock is computed by dividing the net loss using the weighted-average number of common shares and, if dilutive, potential common shares outstanding during the period. Potential common shares consist of stock options and warrants to purchase common stock (using the treasury stock method). Restatement of Consolidated Financial Statements as of and for the year ended December 31, 2020 As part of the Business Combination, the Company originally completed a comprehensive evaluation and concluded that the public and private warrants, as described in Notes 4 and 13, that were initially issued by Spartan could be classified within equity. Subsequent to filing the Company's Annual Report on Form 10-K for the year ended December 31, 2020 on March 30, 2021, the Staff of the Securities and Exchange Commission issued a public statement (the “Statement”) entitled “Staff Statement on Accounting and Reporting Considerations for Warrants Issued by Special Purpose Acquisition Companies (“SPACs”)” on April 12, 2021 stating that warrants issued by SPACs may require classification as a liability of the entity measured at fair value, with changes in fair value each period reported in earnings. Based on the review of the Company’s historical accounting pursuant to ASC 815, Derivatives and Hedging (Topic 815) (“ASC 815”), and after considering the Statement, the Company concluded its Warrants require classification as derivative liabilities to be measured at their fair values as of the closing of the Business Combination, with subsequent changes in fair value remeasured through earnings. The accounting for the Warrants does not impact the Company’s financial statements in any reporting periods prior to the Business Combination, as the Company assumed the Warrants through the Business Combination which was accounted for as a reverse recapitalization. The fair value of the Warrants as of the closing date of the Business Combination on October 29, 2020 and December 31, 2020 amounted to $62.7 million and $138.1 million, respectively. During the fourth quarter of 2020, the change in fair value from October 29, 2020 through December 31, 2020 amounted to an increase of $75.4 million. The Company concluded the effect of this error on the previously reported consolidated financial statements as of and for the year ended December 31, 2020 is material and, as such, on May 17, 2021 restated the December 31, 2020 consolidated financial statements, and accompanying notes from the amounts previously reported to give effect to the correction of this error. Recently Adopted Accounting Pronouncements In September 2020, the FASB issued ASU 2020-06, Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging-Contracts in Entity’s Own Equity (Subtopic 815-40) . This ASU simplifies the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts on an entity’s own equity. The ASU eliminates the current models that require separation of beneficial conversion and cash conversion features from convertible instruments and simplifies the derivative scope exception guidance pertaining to equity classification of contracts in an entity’s own equity. The ASU also introduces additional disclosures for convertible In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments |
