Summary Of Significant Accounting Policies [Abstract] |
Basis Of Presentation And Consolidation | 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. Translation adjustments resulting from translating foreign subsidiaries’ results of operations and assets and liabilities into U.S. dollars are immaterial for all periods presented.
Use Of Estimates | Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes to the financial statements. Our estimates include, but are not limited to, the valuation of inventory, revenue valuation, the valuation of a financing derivative and long-term notes, the valuation and recognition of share-based compensation, the delivery period for collaboration agreements, the useful lives assigned to long-lived assets, and the computation provisions for income taxes. Actual results could differ materially from these estimates. During 2017, we recorded a charge to cost of service and other revenue of $1.6 million relating to leased RS II instruments primarily due to a change in the estimated useful life of these instruments. The charge of $1.6 million increased loss per share by $0.01 for the year ended December 31, 2017.
Fair Value Of Financial Instruments | Fair Value of Financial Instruments The carrying amount of our accounts receivable, prepaid expenses, other current assets, accounts payable, accrued expenses and other liabilities, current, approximate fair value due to their short maturities. The carrying value of our other liabilities, non-current, approximates fair value due to the time to maturity and prevailing market rates. The fair value hierarchy established under U.S. GAAP requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. A financial instrument’s categorization within the fair value hierarchy is based upon the lowest level input that is significant to the fair value measurement. The three levels of inputs that may be used to measure fair value are as follows:
| • |  | 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 in active markets for similar assets or liabilities, quoted prices for identical or similar assets or liabilities 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; and
| • |  | Level 3: unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
We consider an active market as one in which transactions for the asset or liability occurs with sufficient frequency and volume to provide pricing information on an ongoing basis. Conversely, we view an inactive market as one in which there are few transactions for the asset or liability, the prices are not current, or price quotations vary substantially either over time or among market makers. Where appropriate, our non-performance risk, or that of our counterparty, is considered in determining the fair values of liabilities and assets, respectively. We classify our cash deposits and money market funds within Level 1 of the fair value hierarchy because they are valued using bank balances or quoted market prices. We classify our investments as Level 2 instruments based on market pricing and other observable inputs. We did not classify any of our investments within Level 3 of the fair value hierarchy. Assets and liabilities measured at fair value are classified in their entirety based on the lowest level input that is significant to the fair value measurement. Our assessment of the significance of a particular input to the entire fair value measurement requires management to make judg e ments and consider factors specific to the asset or liability. Assets and Liabilities Measured at Fair Value on a Recurring Basis The following table sets forth the fair value of our financial assets and liabilities that were measured on a recurring basis as of December 31, 2017 and December 31, 2016 respectively (in thousands): ﻿

﻿ The estimated fair value of the Financing Derivative liability (as defined in “Note 6. Notes Payable’) was determined using Level 3 inputs, or significant unobservable inputs. Refer to “Note 6. Notes Payable” for a detailed description and valuation approach. Changes to the estimated fair value of the Financing Derivative are recorded in “Other income (expense), net” in the consolidated statements of operations and comprehensive loss. The following table provides the changes in the fair value of the Financial Derivative for the year ended December 31, 2017 and 2016 (in thousands), respectively: ﻿
﻿ |  |  |

﻿Financing Derivative |  | Amount
﻿Balance as of December 31, 2015 |  | $ | 600

﻿Change in fair value due to partial exercise of derivative associated with $4.5 million principal payoff |  |  | (826)
﻿Balance as of December 31, 2017 |  | $ | 183
﻿ |  |  |
﻿ For the year ended December 31, 2017, there were no transfers between Level 1, Level 2, or Level 3 assets or liabilities reported at fair value on a recurring basis and our valuation techniques did not change compared to the prior year. Financial Assets and Liabilities Not Measured at Fair Value on a Recurring Basis The carrying amount of our accounts receivable, prepaid expenses, other current assets, accounts payable, accrued expenses and other current liabilities approximate fair value due to their short maturities. We determined the fair value of the Notes (as defined in “Note 6. Notes Payable”) from the debt facility we entered into during the first quarter of 2013 using Level 3 inputs, or significant unobservable inputs. The value of the Notes was determined by comparing the difference between the fair value of the Notes with and without the Financing Derivative by calculating the respective present values from future cash flows using a 10.3% and 10.6% weighted average market yield at December 31, 2017 and December 31, 2016, respectively. Refer to “Note 6. Notes Payable” for additional details regarding the Notes. The estimated fair value and carrying value of the Notes are as follows (in thousands): ﻿

﻿
Cash And Cash Equivalents | Cash and Cash Equivalents We consider all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents.
Investments | Investments We have designated all investments as available-for-sale and therefore, such investments are reported at fair value, with unrealized gains and losses recognized in accumulated other comprehensive income (loss) (“OCI”) in stockholders’ equity. The cost of marketable securities is adjusted for the amortization of premiums and discounts to expected maturity. Premium and discount amortization is included in other income, net. Realized gains and losses, as well as interest income, on available-for-sale securities are also included in other income, net. The cost of securities sold is based on the specific identification method. We include all of our available-for-sale securities in current assets. All of our investments are subject to a periodic impairment review. We recognize an impairment charge when a decline in the fair value of our investments below the cost basis is judged to be other-than-temporary. Factors considered in determining whether a loss is temporary include the length of time and extent to which an investment’s fair value has been less than its cost basis, the financial condition and near-term prospects of the investee, extent of the loss related to credit of the issuer, the expected cash flows from the security, our intent to sell the security and whether or not we will be required to sell the security before the recovery of its amortized cost. During the years ended December 31, 2017, 2016 and 2015, we did not recognize any impairment charges on our investments as it is more likely than not that we will recover their amortized cost basis upon sale or maturity.
Concentration And Other Risks | Concentration and Other Risks 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. Our accounts receivable are derived from net 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. We regularly review our accounts receivable including consideration of factors such as historical experience, credit quality, the age of the accounts receivable balances and current economic conditions that may affect a customer’s ability to pay. We have not experienced any significant credit losses to date. Excluding contractual revenue from the Roche agreement, which has now been terminated, for the year ended December 31, 2017, one customer, Gene Company Limited, accounted for approximately 31% of our total revenue, for the years ended December 31, 2016 and 2015, no customer accounted for more than 10% of our total revenue. As of both December 31, 2017 and 2016, 84% of our accounts receivable were from domestic customers. As of December 31, 2017, one c ustomer, Gene Company Limited, represented approximately 20% of our net accounts receivable. As of December 31, 2016, no customer represented more than 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. However, 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 | Inventory We early adopted the Accounting Standards Update (“ASU”) No. 2015-11, Simplifying the Measurement of Inventory in the year ended December 31, 2016 effective January 1, 2016. The adoption did not result in any material impact to inventory. As a result, our inventories are stated at the lower of average cost or net realizable value. Cost is determined using the 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.
Property And Equipment, Net | Property and Equipment, Net Property and equipment are stated at cost, net of accumulated depreciation and any impairment charges. Depreciation is computed using the straight-line method over the estimated useful life of the asset, generally two to three years for computer equipment, three to five years for software, three to seven years for furniture and fixtures, three to five years for lab equipment and 30 years for buildings. 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.
Long-Term Restricted Cash | Long-term Restricted Cash As required under the lease agreement for our corporate offices (the “O’Brien lease”), we were required to establish a letter of credit for the benefits of the landlord and to submit $4.5 million as a deposit for the letter of credit in October 2015; and, as such, $4.5 million was recorded in “Long-term restricted cash” in the consolidated balance sheet as of such year and continued to be so recorded as of both December 31, 2017 and December 31, 2016.
Impairment Of Long-Lived Assets | Impairment of Long-Lived Assets We periodically review property and equipment for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset is impaired or the estimated useful lives are no longer appropriate. Fair value is estimated based on discounted future cash flows. If indicators of impairment exist and the undiscounted projected cash flows associated with such assets are less than the carrying amount of the asset, an impairment loss is recorded to write the asset down to its estimated fair value. To date, we have not recorded any impairment charges.
Revenue Recognition | Revenue Recognition Our revenue is generated primarily from the sale of products and services, in addition to revenue from collaboration agreements. Product revenue consists of sales of our instruments and related consumables; Service and other revenue primarily consist of revenue earned from product maintenance agreements, instrument lease agreements and grant revenue. Contractual revenue relates to revenue recognized from the collaboration agreement under which we received an upfront fee and may receive contingent milestone payments. Our deliverables under the arrangement include licenses to intellectual property rights and research and development services. We recognize revenue when persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, the price is fixed or determinable, and collectability is reasonably assured. For instances where final acceptance of the product or system is required, revenue is deferred until all acceptance criteria have been met. Revenue for product sales is generally recognized upon customer acceptance. For certain qualified distributors revenue is recognized based upon shipment terms. Revenue for product maintenance agreements is recognized when earned, which is generally ratably over the service period. In order to assess whether the price is fixed or determinable, we evaluate whether refund rights exist. If refund rights exist or payment terms are based on future performance, we defer revenue recognition until the price becomes fixed or determinable. We assess collectability based on a number of factors, including customer creditworthiness. If we determine that collection of amounts due is not reasonably assured, revenue recognition is deferred until receipt of payment. We regularly enter into arrangements, comprised of one or more contracts, from which revenue is derived from multiple deliverables including a mix of products and or services. Revenue recognition for contracts with multiple deliverables is based on the individual units of accounting determined to exist in the contract. A delivered item is considered a separate unit of accounting when (i) the delivered item has value to the customer on a stand-alone basis; and (ii) if a general right of return exists, the delivery or performance of an undelivered item is considered probable and under our control. Items are considered to have stand-alone value when they are sold separately by any vendor or when the customer could resell the item on a stand-alone basis. Our revenue arrangements generally do not have a general right of return. When a deliverable does not meet the criteria to be considered a separate unit of accounting, we group it with other deliverables that, when combined, meet the criteria, and the appropriate allocation of arrangement consideration and revenue recognition is determined. Consideration is allocated at the inception of the contract to all deliverables based on their relative selling price. In order to determine the relative selling price of a deliverable, we apply, in order, vendor-specific objective evidence (“VSOE”); third-party evidence if VSOE is not available; and lastly our best estimate of selling price for the deliverable if neither VSOE nor third-party evidence is available. In order to establish VSOE, we must regularly sell the product or service on a standalone basis with a substantial majority of sales priced within a relatively narrow range. If an insufficient number of standalone sales exist and VSOE cannot be determined, we then consider whether third party evidence can be used to establish selling price. Due to the lack of similar products and services sold by other companies within our industry, we have not established selling price using third-party evidence. If neither VSOE nor third party evidence of selling price exists, we determine our best estimate of selling price using a combination of prices set by our pricing committee adjusted for applicable discounts and customer orders received to date. Deferred service revenue primarily represents product maintenance agreement revenue that is expected to be recognized over the related service period, generally one to three years. For instrument lease agreements we entered into with our customers, they are classified as operating-type leases and revenue from these leases is recognized on a straight-line basis over the respective lease term, once the lessee takes (or has the right to take) control/possession of the property under the lease. Effectively, this occurs once installation is complete and acceptance has been obtained.
Cost Of Revenue | ﻿ 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. There are no incremental costs associated with our contractual revenue; all product development costs are reflected in research and development expense. Manufacturing overhead is predominantly comprised of labor and facility costs. We determine and 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 the installed customer base.
Research And Development | Research and Development Research and development expense consists primarily of expenses for personnel engaged in the development of our SMRT Sequencing technology, the design and development of our future products and current product enhancements. These expenses also include prototype-related expenditures, development equipment and supplies, facilities costs and other related overhead. We expense research and development costs during the period in which the costs are incurred. However, 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.
Leases | Leases We categorize leases at their inception as either operating or capital leases. On certain of our lease agreements, we may receive tenant improvement allowances, rent holidays and other incentives. Rent expense is recorded on a straight-line basis over the term of the lease. The difference between rent expense recognized and amounts paid under the lease agreement is recorded as deferred rent in the balance sheets. Leasehold improvements are capitalized at cost and depreciated over the shorter of their expected useful life or the life of the lease. Tenant improvements afforded to us by landlord incentives are recorded as leasehold improvement assets with corresponding deferred rent liabilities. For build-to-suit lease arrangements, we evaluate the extent of our financial and operational involvement in the tenant improvements to determine whether we are considered the owner of the construction project under U.S. GAAP. When we are considered the owner of a project, we record the shell of the facility at its fair value at the date construction commences with a corresponding facility financing obligation. Improvements to the facility during the construction project are capitalized and, to the extent funded by lessor afforded incentives, with corresponding increases to the facility financing obligation. Payments we make under leases in which we are considered the owner of the facility are allocated to land rental expense, based on the relative values of the land and building at the commencement of construction, reductions of the facility financing obligation and interest expense recognized on the outstanding obligation. To the extent gross future payments do not equal the recorded liability, the liability is settled upon return of the facility to the lessor. Any difference between the book value of the assets and remaining facility obligation are recorded in other expense, net. For existing arrangements, the differences are expected to be immaterial.
Income Taxes | 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 basis 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. 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 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 would accrue the estimated amount of tax related to such uncertain positions.
Stock-Based Compensation | Stock-based Compensation Stock-based compensation expense for all stock-based compensation awards is based on the grant date fair value estimated using the Black-Scholes option pricing model. We have limited historical information available to support the underlying estimates of certain assumptions required to value stock options. The expected term of options is estimated based on the simplified method. We do not have sufficient trading history to solely rely on the volatility of our own common stock for establishing expected volatility. Therefore, we based our expected volatility on the historical stock volatilities of our common stock as well as several comparable publicly listed companies over a period equal to the expected term of the options. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for the expected term of the stock option. We estimate our forfeiture rate based on an analysis of our actual forfeitures and will continue to evaluate the adequacy of the forfeiture rate based on actual forfeiture experience, analysis of employee turnover behavior and other factors. The impact from a forfeiture rate adjustment will be recognized in full in the period of adjustment, and if the actual number of future forfeitures differs from that which was estimated, we may be required to record adjustments to stock-based compensation expense in future periods. We recognize compensation expense on a straight-line basis over the requisite service period. We elected to use the simplified method to calculate the beginning pool of excess tax benefits.
Other Comprehensive Income (Loss) | Other Comprehensive Income (loss) Other comprehensive income (loss) is comprised of unrealized gains (losses) on our investment securities.
Recent Accounting Pronouncements | Recent Accounting Pronouncements ﻿ Recently Adopted Accounting Standards In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, which amends the current stock compensation guidance. The amendments simplify the accounting for the taxes related to stock-based compensation, including adjustments to how excess tax benefits and a company's payments for tax withholdings should be classified. Furthermore, the amendments allow the entities to make an accounting policy election to either estimate forfeitures or recognize forfeitures as they occur. We adopted this guidance as of January 1, 2017. Prior to adoption, the excluded windfall deductions for federal and state purposes were $6.0 million and $0.6 million, respectively. Upon adoption of ASU 2016-09, we recognized the excluded windfall deductions as a deferred tax asset with a corresponding increase to valuation allowance. Our total deferred tax assets were $321.5 million as of January 1, 2017, and were fully offset by a valuation allowance. Further, we did not elect an accounting policy change to record forfeitures as they occur and thus we continue to estimate forfeitures at each period. During August 2014, the FASB issued ASU No. 2014-15, Presentation of Financial Statements – Going Concern Disclosure of Uncertainties About an Entity’s Ability to Continue as a Going Concern, which requires management to evaluate whether there are conditions or events that raise substantial doubt about an entity’s ability to continue as a going concern in the next 12 months from the filing date of the Annual Report on Form 10-K for the year ended December 31, 2017 and to provide disclosures when certain criteria are met. The guidance is effective for annual periods beginning after December 15, 2016 and interim reporting periods starting in the first quarter of 2017. We adopted this standard as of December 31, 2016. Cash, cash equivalents and investments at December 31, 2017 totaled $62.9 million, compared to $72.0 million at December 31, 2016. We believe that our existing cash, cash equivalents and investments will be sufficient to fund our projected operating requirements for at least the next 12 months; however, we may raise additional capital in the future. Our view regarding sufficiency of cash and liquidity is primarily based on our financial forecast for 2018, which includes various assumptions regarding demand for our products. Generally, we expect demand for our products to increase. Factors that may affect our capital needs include, but are not limited to, slower than expected adoption of our products resulting in lower sales of our products and services; future acquisitions; our ability to obtain new collaboration and customer arrangements; the progress of our research and development programs; initiation or expansion of research programs and collaborations; litigation costs, including the costs involved in preparing, filing, prosecuting, defending and enforcing intellectual property rights; the purchase of patent licenses; and other factors. ﻿ Recently Issued Accounting Standards In February 2016, the FASB issued ASU 2016-02, Leases. The guidance in ASU 2016-02 supersedes the lease recognition requirements in ASC Topic 840, Leases. ASU 2016-02 requires an entity to recognize assets and liabilities arising from a lease for both financing and operating leases, along with additional qualitative and quantitative disclosures. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, with early adoption permitted. We are currently evaluating the impact of the adoption of this standard on our consolidated financial statements. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, requiring an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The updated standard will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. In August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers: Deferral of the Effective Date, which deferred the effective date of the new revenue standard for periods beginning after December 15, 2016 to December 15, 2017, with early adoption permitted but not earlier than the original effective date. Accordingly, the updated standard is effective for us in the first quarter of 2018. Entities have the option of using either a full retrospective or a modified retrospective approach to adopt this new guidance. While we are continuing to assess all potential impacts of the new standard on our consolidated financial statements, we plan to adopt the standard using the modified retrospective approach with the cumulative effect of adoption, if any, to be recognized as an adjustment to our accumulated deficit on January 1, 2018. The new revenue standard is principle-based and interpretation of those principles may vary from company to company based on their unique circumstances. It is possible that interpretation, industry practice, and guidance may evolve as companies and the accounting profession work to implement this new standard. We are still in the process of evaluating the effect of the new standard on our historical financial statements and disclosures. While we have not completed our evaluation, we currently believe that the impact of adopting the standard will not materially change the amount or timing of our recognition of revenue and related costs. Accordingly, we do not expect to recognize a material adjustment to our accumulated deficit upon adoption on January 1, 2018. As we complete our evaluation of this new standard, new information may arise that could change our current understanding of the impact to revenue and expense recognized. Additionally, we will continue to monitor industry activities and any additional guidance provided by regulators, standards setters, or the accounting profession and adjust our assessment and implementation plans accordingly.
