Organization and Significant Accounting Policies[Abstract]
Organization and Significant Accounting Policies	NOTE 1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES We are a life science technology company that designs, develops, and manufactures advanced sequencing solutions to help scientists and clinical researchers 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 existing HiFi long read sequencing technology and our emerging short read Sequencing by Binding (SBB^®) technology. Our products address solutions across a broad set of applications including human germline sequencing, plant and animal sciences, infectious disease and microbiology, oncology, and other emerging applications. Our focus is on providing our customers with advanced sequencing technologies with higher throughput and improved workflows that we believe will enable dramatic advancements in routine healthcare. 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 unaudited condensed 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 unaudited condensed consolidated financial statements include the accounts of Pacific Biosciences and our wholly owned subsidiaries. Certain information and footnote disclosures typically included in our audited financial statements have been condensed or omitted. The accompanying unaudited condensed consolidated financial statements have been prepared on a consistent basis with the December 31, 2021 audited consolidated financial statements and include all adjustments, consisting of only normal recurring adjustments, necessary to fairly state our financial position, results of operations, comprehensive income (loss), and cash flows for the period, but are not necessarily indicative of the results to be expected for the entire year or any future periods. All intercompany transactions and balances have been eliminated. The financial statements should be read in conjunction with the audited consolidated financial statements and notes included in our Annual Report on Form 10-K for the year ended December 31, 2021. 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 determination of stand-alone selling prices for revenue recognition, the fair value of contingent consideration, the valuation of acquired intangible assets, the fair value of certain equity awards, the useful lives assigned to long-lived assets, the computation of provisions for income taxes, the borrowing rate used in calculating the operating lease right-of-use assets and operating lease liabilities, the probability associated with variable payments under partnership development agreements, and the valuations related to our convertible senior notes. While the extent of the potential impact of the ongoing COVID-19 pandemic 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 June 30, 2022. Actual results could differ materially from these estimates. Cash, Cash Equivalents, 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 (loss) income 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. Concentration and Other Risks For the three months ended June 30, 2022, one customer accounted for approximately 11% of total revenue during the period. For the six months ended June 30, 2022, no customers exceeded 10%. For the three and six months ended June 30, 2021, one customer accounted for approximately 17% and 14% of total revenue during the period. No other customers exceeded 10% during those periods. As of June 30, 2022, 57% of our accounts receivable were from domestic customers, compared to 53% as of December 31, 2021. As of June 30, 2022, one customer represented 11% of our accounts receivable, while no customer represented 10% or greater of our net accounts receivable as of December 31, 2021. Recent Accounting Pronouncements Recently Adopted Accounting Standards There are no accounting standards updates (“ASUs”) that have been recently adopted. Significant Accounting Policies There have been no changes to our significant accounting policies as disclosed in the Annual Report on Form 10-K for the fiscal year ended December 31, 2021, however, as a result of certain changes to the standard contractual terms and conditions with customers implemented during the quarter ended March 31, 2022, we concluded that a change in the application of our accounting policy, in accordance with ASC 606, was appropriate. Specifically, we modified the standard contractual terms with customers during the first quarter of 2022, to reflect transfer of title and risk of loss and right to invoice upon delivery. We also updated the terms of the warranty provided with the instrument to remove the service component. As a result, the warranty is no longer a separate performance obligation and, accordingly, we accrue for the cost of the assurance warranty when revenue of the instrument is recognized. In addition, because of technical enhancements associated with our more recent instrument releases, including the Sequel IIe systems, installation services are now distinct from the instrument itself. Therefore, instrument revenue is now recognized upon transfer of control of the asset to the customer, which is generally upon delivery for sales made to our non-distributor customers.
