ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES | ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES Business Overview We are a life science technology company that is designing, developing, and manufacturing advanced sequencing solutions that enable scientists and clinical researchers to improve their understanding of the genome and ultimately, resolve genetically complex problems. Our products and technology under development stem from two highly differentiated core technologies focused on accuracy, quality, and completeness, which include our HiFi long-read sequencing technology and our Sequencing by Binding (SBB ® ) technology. Our products address solutions across a broad set of applications including human genetics, plant and animal sciences, infectious disease and microbiology, oncology, and other emerging applications. Our focus is on creating some of the world's most advanced sequencing systems to provide our customers the most complete and accurate view of genomes, transcriptomes, and epigenomes. Our customers include academic and governmental research institutions, commercial testing and service laboratories, genome centers, public health labs, hospitals and clinical research institutes, contract research organizations (CROs), pharmaceutical companies, and agricultural companies. References in this report to “PacBio,” “we,” “us,” the “Company,” and “our” refer to Pacific Biosciences of California, Inc. and its consolidated subsidiaries. Basis of Presentation and Consolidation Our consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States, or U.S. GAAP, as set forth in the Financial Accounting Standards Board, or FASB, Accounting Standards Codification, or ASC. The consolidated financial statements include the accounts of Pacific Biosciences and our wholly owned subsidiaries. All intercompany transactions and balances have been eliminated. Certain prior period amounts have been reclassified to conform to the current period presentation. Use of Estimates The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes to the financial statements. On an ongoing basis, we evaluate our significant estimates including, but not limited to, the valuation of inventory, the fair value of contingent consideration, the valuation of acquired intangible assets, the useful lives assigned to long-lived assets, the computation of provisions for income taxes, and the valuations related to our convertible senior notes. While the extent of the potential impact of the current macroeconomic conditions on our business is highly uncertain, we considered information available related to assumptions and estimates used to determine the results reported and asset valuations as of December 31, 2023. Actual results could differ materially from these estimates. Functional Currency The U.S. dollar is the functional currency of our international operations. We remeasure foreign subsidiaries monetary assets and liabilities to the U.S. dollar and record net gains or losses from remeasurement in other income, net, in the consolidated statements of operations and comprehensive loss. Cash, Cash Equivalents, Restricted Cash, and Investments We consider all highly liquid investments purchased with an original maturity of 90 days or less to be cash equivalents. Cash equivalents may be comprised of money market funds, certificates of deposit, commercial paper, corporate bonds and notes, and government agencies’ securities. We classify our investments in debt securities as available-for-sale and report the investments at fair value in current assets. We evaluate our available-for-sale investments in unrealized loss positions and assess whether the unrealized loss is credit-related. Unrealized gains and losses that are not credit-related are recognized in accumulated other comprehensive income (loss) in stockholders’ equity. Realized gains and losses, expected credit losses, as well as interest income, on available-for-sale securities are also reported in other income, net. The cost used in the determination of gains and losses of securities sold is based on the specific identification method. The cost of marketable securities is adjusted for the amortization of premiums and discounts to expected maturity. Premium and discount amortization is recorded in other income, net. Our investment portfolio at any point in time contains investments in cash deposits, money market funds, commercial paper, corporate debt securities, and U.S. government and agency securities with high credit ratings. We have established guidelines regarding diversification and maturities of investments with the objectives of maintaining safety and liquidity, while maximizing yield. Restricted cash includes cash that is not readily available for use in the Company’s operating activities. Restricted cash is primarily comprised of cash pledged under letters of credit. Concentration and Other Risks Financial instruments that potentially subject us to credit risk consist principally of interest-bearing investments and trade receivables. We maintain cash, cash equivalents, and investments with various major financial institutions. The counterparties to the agreements relating to our investment securities consist of various major corporations, financial institutions, municipalities, and government agencies of high credit standing. At December 31, 2023, most of our cash was deposited with U.S. financial institutions. Our investment policy generally restricts the amount of credit exposure to any one issuer. There is no limit to the percentage of the portfolio that may be maintained in securities issued by the U.S. Treasury and U.S. Government Agencies, or other securities fully backed by U.S. Treasury or Government agencies. We have not experienced significant credit losses from financial institutions. Our trade receivables are derived from revenue to customers and distributors located in the United States and other countries. We perform credit evaluations of our customers’ financial condition and, generally, require no collateral from our customers. The allowance for credit losses is based on our assessment of the collectability of customer accounts. We regularly review our trade receivables including consideration of factors such as historical experience, the age of the accounts receivable balances, customer creditworthiness, customer industry, and current and forecasted economic conditions that may affect a customer’s ability to pay. We have not experienced any significant credit losses to date. Although we have historically not experienced significant credit losses, our exposure to credit losses may increase if our customers are adversely affected by changes in economic pressures or uncertainty associated with local or global economic recessions, or other customer-specific factors. For the year ended December 31, 2023, no single customer accounted for 10% or greater of our total revenue. For the years ended December 31, 2022 and 2021, one customer accounted for approximately 12%, and 13% of our total revenue, respectively. As of December 31, 2023 and 2022, 49% and 57% of our accounts receivable were from domestic customers, respectively. As of December 31, 2023, one customer represented approximately 10% of our net accounts receivable. As of December 31, 2022, one customer represented approximately 10% of our net accounts receivable. We currently purchase several key parts and components used in the manufacture of our products from a limited number of suppliers. Generally, we have been able to obtain an adequate supply of such parts and components but in certain instances have incurred additional costs to secure a supply of constrained material. An extended interruption in the supply of parts and components currently obtained from our suppliers could adversely affect our business and consolidated financial statements. Inventory, Net Inventories are stated at the lower of cost or net realizable value on a first-in, first-out (“FIFO”) method. Adjustments to reduce the cost of inventory to its net realizable value, if required, are made for estimated excess or obsolete balances. Cost includes depreciation, labor, material, and overhead costs, including product and process technology costs. Determining net realizable value of inventories involves numerous judgements, including projecting future average selling prices, sales volumes, and costs to complete products in work in process inventories. We make inventory purchases and commitments to meet future shipment schedules based on forecasted demand for our products. The business environment in which we operate is subject to rapid changes in technology and customer demand. We perform a detailed assessment of inventory each period, which includes a review of, among other factors, demand requirements, product life cycle and development plans, component cost trends, product pricing, product expiration, and quality issues. Based on our analysis, we record adjustments to inventory for potentially excess, obsolete, or impaired goods, when appropriate, to report inventory at net realizable value. Inventory adjustments may be required if actual demand, component costs, supplier arrangements, or product life cycles differ from our estimates. Any such adjustments would result in a charge to our results of operations. Property and Equipment, Net Property and equipment are stated at cost, reviewed regularly for impairment, and depreciated over the estimated useful lives of the assets, using the straight-line method. Leasehold improvements are depreciated over the shorter of the lease term or the estimated useful life of the related asset. Major improvements are capitalized, while maintenance and repairs are expensed as incurred. Transfers of assets between property and equipment, net, and inventory are transferred at standard cost and recognized at carrying value. Estimated useful lives of the major classes of property and equipment are as follows: Estimated Useful Lives Leasehold improvements 3 to 10 years Lab equipment 3 to 5 years Computer equipment 3 to 5 years Computer software 3 years Furniture and fixtures 3 to 5 years Operating Leases We record operating lease right-of-use assets and liabilities on our consolidated balance sheets for all leases with a term of more than 12 months. The operating lease right-of-use assets and liabilities are calculated as the present value of remaining minimum lease payments over the remaining lease term using our estimated secured incremental borrowing rates at the commencement date. Lease payments included in the measurement of the lease liability comprise the fixed rent per the term of the Lease. Operating lease expense is recognized on a straight-line basis over the lease term, with variable lease payments, such as common area maintenance fees, recognized in the period incurred. Business Combinations Under the acquisition method of accounting, we allocate the fair value of the total consideration transferred to the tangible and identifiable intangible assets acquired and liabilities assumed based on their estimated fair values on the date of acquisition. These valuations require us to make estimates and assumptions, especially with respect to intangible assets. We record the excess consideration over the aggregate fair value of tangible and intangible assets, net of liabilities assumed, as goodwill. Costs that we incur to complete the business combination, such as legal and other professional fees, are expensed as they are incurred. In connection with certain acquisitions, contingent consideration can be earned by the sellers upon completion of certain future performance milestones. In these cases, a liability is recorded on the acquisition date for an estimate of the acquisition date fair value of the contingent consideration. These estimates require significant management judgment, including probabilities of achieving certain future milestones. Changes in the fair value of the contingent consideration subsequent to the acquisition date are recognized in operating expense in our consolidated statements of operations and comprehensive loss. If the initial accounting for a business combination is incomplete by the end of a reporting period that falls within the measurement period, we report provisional amounts in our financial statements. During the measurement period, we adjust the provisional amounts recognized at the acquisition date to reflect new information obtained about facts and circumstances that existed as of the acquisition date that, if known, would have affected the measurement of the amounts recognized as of that date. We record these adjustments to the provisional amounts with a corresponding offset to goodwill. Any adjustments identified after the measurement period are recorded in the consolidated statements of operations and comprehensive loss. Goodwill, Intangible Assets, and Other Long-Lived Assets Assets acquired, including intangible assets and capitalized in-process research and development (“IPR&D”), and liabilities assumed are measured at fair value as of the acquisition date. Goodwill, which has an indefinite useful life, represents the excess of cost over fair value of the net assets acquired. Intangible assets acquired in a business combination that are used for IPR&D activities are considered indefinite lived until the completion or abandonment of the associated research and development efforts. Upon reaching the end of the relevant research and development project (i.e., upon commercialization), the IPR&D asset is assessed for impairment and then amortized over its estimated useful life. If the relevant research and development project is abandoned, the IPR&D asset is expensed in the period of abandonment. Goodwill and IPR&D are not amortized; however, they are reviewed for impairment at least annually. We perform annual impairment testing of goodwill in the second quarter of each year, or more frequently if indicators of potential impairment exist. We generally perform annual impairment testing of IPR&D in the fourth quarter of each year, or more frequently if indicators of potential impairment exist. We perform our goodwill impairment analysis at the reporting unit level. We have one reporting unit, which aligns with our reporting structure and availability of discrete financial information. During the goodwill impairment review, we assess qualitative factors to determine whether it is more likely than not that the fair values of our reporting unit is less than the carrying amount, including goodwill. The qualitative factors include, but are not limited to, macroeconomic conditions, industry and market considerations, and our overall financial performance. If, after assessing the totality of these qualitative factors, we determine that it is not more likely than not that the fair value of our reporting unit is less than the carrying amount, then no additional assessment is deemed necessary. Otherwise, we proceed to compare the estimated fair value of the reporting unit with the carrying value, including goodwill. If the carrying amount of the reporting unit exceeds the fair value, we record an impairment loss based on the difference. We may elect to bypass the qualitative assessment in a period and proceed to perform the quantitative goodwill impairment test. During the IPR&D impairment review, we assess qualitative factors to determine whether it is more likely than not that the fair value of the IPR&D is less than the carrying amount. The qualitative factors include, but are not limited to, macroeconomic conditions, industry-specific conditions, and company-specific conditions. If, after assessing the totality of these qualitative factors, we determine that it is not more likely than not that the fair value of the IPR&D is less than the carrying amount, then no additional assessment is deemed necessary. Otherwise, we proceed to compare the estimated fair value of the IPR&D with the carrying value. If the carrying amount of the IPR&D exceeds the fair value, we record an impairment loss based on the difference. We may elect to bypass the qualitative assessment in a period and proceed to perform the quantitative impairment test. Finite-lived intangibles assets include our acquired developed technology and customer relationships. We capitalize finite-lived intangibles assets and generally amortize them on a straight-line basis over the estimated useful lives. We regularly review the carrying amount and useful lives of our finite-lived assets to determine whether indicators of impairment may exist which warrant adjustments to carrying values or estimated useful lives. If indicators of impairment exist, an impairment test is performed to assess the recoverability of the affected assets by determining whether the carrying amount of such assets exceeds the undiscounted expected future cash flows. If the affected assets are not recoverable, we estimate the fair value of the assets and record an impairment loss if the carrying value of the assets exceeds the fair value. Factors that may indicate potential impairment include a significant decline in our stock price and market capitalization compared to the net book value, significant changes in the ability of a particular asset to generate positive cash flows for our strategic business objectives, and the pattern of utilization of a particular asset. Revenue Recognition Our revenue is generated primarily from the sale of products and services. Product revenue primarily consists of sales of our instruments and related consumables; service and other revenue consist primarily of revenue earned from product maintenance agreements. We account for a contract with a customer when there is a legally enforceable contract between us and the customer, the rights of the parties are identified, the contract has commercial substance, and collectability of the contract consideration is probable. Revenues are recognized when control of the promised goods are transferred to our customers, or services are performed, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services. We may enter into contracts with customers that include a combination of promised products and services, resulting in arrangements containing multiple performance obligations. We determine whether each product or service is distinct, in order to identify the performance obligations in the contract and allocate the contract transaction price among the distinct performance obligations. A performance obligation is considered distinct from other obligations in a contract when it provides a benefit to the customer either on its own or together with other resources that are readily available to the customer and is separately identified in the contract. We consider a performance obligation satisfied once we have transferred control of a good or service to the customer, meaning the customer has the ability to use and obtain the benefit of the good or service. Therefore, instrument revenue is recognized upon transfer of control of the asset to the customer, which is generally upon delivery for sales made to our non-distributor customers and upon shipment for sales made to our distributor customers. The consideration for contracts with multiple performance obligations is allocated between separate performance obligations based on their individual standalone selling price. We determine the best estimate of standalone selling price using average selling prices over a 12-month period combined with an assessment of current market conditions. If the standalone selling price is not directly observable, we rely on estimates by considering multiple factors including, but not limited to, overall market conditions, including geographic or regional specific factors, internal costs, profit objectives, pricing practices, and other observable inputs. We recognize revenues as performance obligations are satisfied by transferring control of the product or service to the customer or over the term of a product maintenance agreement with a customer. Our revenue arrangements generally do not provide a right of return. Revenue is recorded net of discounts and sales taxes collected on behalf of governmental authorities. Certain of our agreements provide options to customers which can be exercised at a future date, such as the option to purchase our product at discounted prices, among others. In accounting for customer options, we determine whether an option is a material right and this requires us to exercise significant judgment. If a contract provides the customer an option to acquire additional goods or services at a discount that exceeds the range of discounts that we typically give for that product or service for the same class of customer, or if the option provides the customer certain additional goods or services for free, the option may be considered a material right. If the contract gives the customer the option to acquire additional goods or services at their normal standalone selling prices, we would likely determine that the option is not a material right and, therefore, account for it when the customer exercises the option. If the standalone selling price of the option is not directly observable, an estimated standalone selling price is utilized which considers adjustments for discounts that the customer could receive without exercising the option and the likelihood that the option will be exercised. We may also utilize the alternative approach to estimate the standalone selling price, available pursuant to the applicable accounting guidance, to the extent we conclude the applicable criteria for using the alternative approach has been met. We update the transaction price for expected consideration, subject to constraint, each reporting period if our estimate of future goods to be ordered by customers change. Additionally, we generally provide a one-year warranty on instruments. We accrue the cost of the assurance warranty when revenue of the instrument is recognized. Employee sales commissions are generally recorded as selling, general, and administrative expense when incurred as the amortization period for such costs, if capitalized, would have been one year or less. Cost of Revenue Cost of revenue reflects the direct cost of product components, third-party manufacturing services, and our internal manufacturing overhead and customer service infrastructure costs incurred to produce, deliver, maintain, and support our instruments, consumables, and services. Manufacturing overhead is predominantly comprised of labor and facility costs. We capitalize manufacturing overhead into inventory based on a standard cost model that approximates actual costs. Service costs include the direct costs of components used in support, repair and maintenance of customer instruments as well as the cost of personnel, materials, shipping and support infrastructure necessary to support our installed customer base. Research and Development Research and development expense consists primarily of expenses for personnel engaged in the development of our core technology, the design and development of our future products and current product enhancements. These expenses also include prototype-related expenditures, development equipment and supplies, partner development costs, facilities costs, and other related overhead. We expense research and development costs during the period in which the costs are incurred. We defer and capitalize non-refundable advance payments made for research and development activities until the related goods are received or the related services are rendered. Credit Losses Trade accounts receivable The allowance for credit losses is based on our assessment of the collectability of customer accounts. We regularly review the allowance by considering factors such as the age of the accounts receivable balances, customer creditworthiness, customer industry, and current and forecasted economic conditions that may affect a customer’s ability to pay. Credit loss expense was immaterial for the years ended December 31, 2023, 2022, and 2021. Available-for-sale debt securities Our investment portfolio contains investments in cash deposits, money market funds, commercial paper, corporate debt securities and U.S. government and agency securities. We regularly assess whether our securities in an unrealized loss position are credit related. The credit-related portion of unrealized losses, and any subsequent improvements, are recorded in interest income. Unrealized losses that are not credit related are included in accumulated other comprehensive income (loss). The unrealized losses on our investments are mainly attributable to government securities, including U.S. government and U.S. agency bond securities, impacted by movements in market rates and not due to issuer credit risk. We have the ability to hold and do not intend to sell the investments in unrealized loss positions before the recovery of their amortized cost bases. Although we have historically not experienced significant credit losses, our exposure to credit losses may increase if our customers are adversely affected by changes in economic pressures or uncertainty associated with local or global economic recessions, disruptions associated with the evolution of COVID-19 or other epidemics or pandemics, or other customer-specific factors. Income Taxes We account for income taxes under the asset and liability method, which requires, among other things, that deferred income taxes be provided for temporary differences between the tax bases of our assets and liabilities and the amounts reported in the financial statements. In addition, deferred tax assets are recorded for the future benefit of utilizing net operating losses and research and development credit carryforwards. The effect of a change in tax rates on the deferred tax assets and liabilities is recognized in the provision for income taxes in the period that includes the enactment date. A full valuation allowance is provided against our net deferred tax assets as it is more likely than not that the deferred tax assets will not be fully realized. We regularly review our positions taken relative to income taxes. To the extent our tax positions are more likely than not going to result in additional taxes, we accrue the estimated amount of tax related to such uncertain positions. Share-based Compensation We recognize share-based compensation expense for share-based payments, including stock options, restricted stock units, performance stock units and stock issued under our employee stock purchase plan ("ESPP") based on the grant-date fair value. We estimate the fair value of stock options and ESPP using an option-pricing model. See Note 10. Stockholders’ Equity for further information regarding share-based compensation. Other Comprehensive Income (Loss) Other comprehensive income (loss) is comprised of unrealized gains (losses) on our investment securities. Shipping and Handling Costs related to shipping and handling are included in cost of revenues for all periods presented. Earnings per Share Basic net loss per share is computed by dividing net loss by the weighted-average number of shares of common stock outstanding during the period. Diluted net loss per share is computed using the weighted-average number of shares of common stock outstanding and potential shares assuming the dilutive effect of outstanding stock options, restricted stock units, and common stock issuable pursuant to our ESPP, using the treasury stock method. Recent Accounting Pronouncements Recently Adopted Accounting Standards In October 2021, the FASB issued Accounting Standards Update ("ASU") No. 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers . This ASU provides specific guidance on how to recognize contract assets and contract liabilities related to revenue contracts with customers acquired in a business combination. This amendment improves comparability for both the recognition and measurement of acquired revenue contracts with customers at the date of and after a business combination. We adopted this ASU on January 1, 2023. The adoption of this guidance did not have a material effect on our consolidated financial statements. Accounting Pronouncements Pending Adoption In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures . This ASU requires entities to expand its existing income tax disclosures, specifically related to the rate reconciliation and income taxes paid. This authoritative guidance will be effective for us in fiscal year 2025, with early adoption permitted. The Company is currently evaluating the impact of the ASU but does not expect any material impacts upon adoption. |
