Organization Consolidation And Presentation Of Financial Statements [Abstract] | |
Description of Business | 1. Description of Business Outset Medical, Inc. (the Company) was originally incorporated on May 5, 2003 in the state of Delaware under the name Home Dialysis Plus, Ltd. The name of the Company was changed to Outset Medical, Inc. on January 5, 2015. Outset Medical, Inc. is a medical technology company pioneering a first-of-its-kind technology to reduce the cost and complexity of dialysis. The Tablo Hemodialysis System, FDA cleared for use from the hospital to the home, represents a significant technological advancement designed to transform the dialysis experience for patients and operationally simplify it for providers. Tablo serves as a single enterprise solution that designed to be utilized across the continuum of care, allowing dialysis to be delivered anytime, anywhere and by anyone. The integration of water purification and on-demand dialysate production enables Tablo to serve as a dialysis clinic on wheels, with 2-way wireless data transmission and a proprietary data analytics platform powering a new holistic approach to dialysis care. The Company’s headquarters are located in San Jose, CA. The Company’s registration statement on Form S-1 related to its initial public offering (IPO) was declared effective by the Securities and Exchange Commission (SEC) on September 14, 2020, and the Company’s common stock began trading on the Nasdaq Global Select Market on September 15, 2020. Upon the completion of the IPO, the Company sold 10,294,000 shares of common stock (which included 1,343,000 shares that were sold pursuant to the full exercise of the underwriters’ option to purchase additional shares in connection with the IPO) at a price to the public of $27.00 per share. Including the full exercise of the underwriters’ option to purchase additional shares, the Company received aggregate net proceeds of approximately $254.8 million after deducting offering costs, underwriting discounts and commissions of approximately $23.1 million. During the year ended December 31, 2020, the Company recognized $18.5 million of cumulative stock-based compensation expense associated with stock options that vest upon the achievement of market and performance conditions satisfied on the effectiveness of the IPO (see Note 9 for further discussion). Reverse Stock Split In September 2020, the Company’s board of directors and shareholders approved a certificate of amendment to the amended and restated certificate of incorporation to effect a reverse split of shares of the Company’s common stock on a 7.9-for-one basis (the Reverse Stock Split) effective as of September 8, 2020. The number of authorized shares and the par values of the common stock and redeemable convertible preferred stock were not adjusted as a result of the Reverse Stock Split. In connection with the Reverse Stock Split, the conversion ratio for the Company’s outstanding redeemable convertible preferred stock was proportionately adjusted such that the common stock issuable upon conversion of such preferred stock was decreased in proportion to the Reverse Stock Split. All references to common stock and options to purchase common stock, share data, per share data and related information contained in these financial statements and related notes have been retrospectively adjusted to reflect the effect of the Reverse Stock Split for all periods presented. Liquidity Since inception, the Company has incurred net losses and negative cash flows from operations. During the years ended December 31, 2020, 2019 and 2018, the Company incurred net losses of $121.5 million, $68.3 million and $49.8 million, respectively. As of December 31, 2020, the Company had an accumulated deficit of $494.1 million. As of December 31, 2020, the Company had cash, cash equivalents and short-term investments of $314.9 million, which are available to fund future operations, and restricted cash of $33.3 million, for a total cash, cash equivalents, restricted cash and short-term investments balance of $348.2 million. Management expects to continue to incur significant expenses for the foreseeable future and to incur operating losses in the near term while the Company makes investments to support its anticipated growth. Management believes that the Company’s existing cash, cash equivalents and short-term investments, which include the proceeds from the IPO, and cash generated from revenues from its products, as well as services and other sales, will be sufficient to meet its anticipated needs for at least the next 12 months from the issuance date of the financial statements. |

These judgments, estimates and assumptions are used for, but not limited to, revenue recognition, allowance for doubtful accounts, inventory valuation and write-downs, warranty obligations, the fair value of common stock and redeemable convertible preferred stock, the fair value of stock options, the fair value of the redeemable convertible preferred stock warrant liability, valuation of investments, recoverability of the Company’s net deferred tax assets and the related valuation allowance, and certain accrued expenses. The Company evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors and adjusts those estimates and assumptions when facts and circumstances dictate. Actual results may differ from those estimates under different assumptions or conditions and the differences may be material. Segment The Company operates as a single operating segment. The Company’s chief operating decision maker, its Chief Executive Officer, reviews financial information on an aggregate basis for the purposes of allocating resources and evaluating financial performance. The Company’s primary operation is in the United States and it has derived its revenue from sales to customers in the United States. The Company has operated a manufacturing facility in Mexico since 2020. T he Company's long-lived tangible assets, as well as the Company's operating lease right-of-use assets recognized on the balance sheets, located in Mexico were $6.0 million as of December 31, 2020. Cash, Cash Equivalents and Restricted Cash As of December 31, 2020, the restricted cash balance of $33.3 million primarily relates to contractual obligations under the SVB Loan and Security Agreement (see Note 7) and collateral for the building leases in San Jose, CA and Tijuana, Mexico. The restricted cash balance of $0.7 million as of December 31, 2019 relates to collateral for the building leases. The Company considers all highly liquid investments purchased with an original maturity of three months or less at the date of purchase to be cash equivalents. As of December 31, 2020 and 2019, the Company’s cash equivalents were held in institutions in the United States and include deposits in a money market fund which were unrestricted as to withdrawal or use. The following table provides a reconciliation of cash, cash equivalents and restricted cash that sum to the total of the amounts shown in the statements of cash flows (in thousands): December 31, 2020 2019 Cash and cash equivalents $ 294,972 $ 36,926 Restricted cash 33,311 743 Total cash, cash equivalents and restricted cash $ 328,283 $ 37,669 Short-Term Investments Short-term investments have been classified as available-for-sale and are carried at estimated fair value as determined based upon quoted market prices or pricing models for similar securities. The Company determines the appropriate classification of its investments in debt securities at the time of purchase. Available-for-sale securities with original maturities beyond three months at the date of purchase are classified as current based on their availability for use in current operations. The Company’s investment securities are recorded at fair value based on the fair value hierarchy. Money market funds and U.S. Treasury securities are classified within Level 1 of the fair value hierarchy. Commercial paper, corporate debt and asset-backed securities are within Level 2 of the fair value hierarchy. Unrealized gains and losses, deemed temporary in nature, are reported as a separate component of accumulated other comprehensive income (loss). A decline in the fair value of any security below cost that is deemed other than temporary results in a charge to earnings and the corresponding establishment of a new cost basis for the security. Premiums (discounts) are amortized (accreted) over the life of the related security as an adjustment to yield using the straight-line interest method. Dividend and interest income are recognized when earned. Realized gains and losses are included in earnings and are derived using the specific identification method for determining the cost of securities sold. Concentration of Credit Risk Financial instruments that potentially subject the Company to a concentration of credit risk consist of cash and cash equivalents, restricted cash, short-term investments and accounts receivable. Substantially all the Company’s cash and cash equivalents, restricted cash and investments are held at one financial institution in the United States that management believes is of high credit quality. Such deposits may, at times, exceed federally insured limits or may not be covered by deposit insurance at all. The Company has not experienced any credit losses on its cash and cash equivalents, restricted cash or short-term investments through December 31, 2020. For the year ended December 31, 2020, three customers accounted for 22%, 19% and 16% of revenues, respectively. One customer accounted for 11% of revenues for the year ended December 31, 2019. Accounts receivable are unsecured and the Company does not require collateral; however, the Company does assess the collectability of accounts receivable based on a number of factors, including past transaction history with, and the creditworthiness of, the customer. Accordingly, the Company is exposed to credit risk associated with accounts receivable. Two customers accounted for 22% and 16% of accounts receivable, respectively, as of December 31, 2020. Four customers accounted for 22%, 13%, 11% and 10% of accounts receivable, respectively, as of December 31, 2019. To reduce risk, the Company closely monitors the amounts due from its customers and assesses the financial strength of its customers through a variety of methods that include, but are not limited to, engaging directly with customer operations and leadership personnel, visiting customer locations to observe operating activities, and assessing customer longevity and reputation in the marketplace. As a result, the Company believes that its accounts receivable credit risk exposure is limited. Fair Value of Financial Instruments The Company determines the fair value of an asset or liability based on the assumptions that market participants would use in pricing the asset or liability in an orderly transaction between market participants at the measurement date. The identification of market participant assumptions provides a basis for determining what inputs are to be used for pricing each asset or liability. A fair value hierarchy has been established which gives precedence to fair value measurements calculated using observable inputs over those using unobservable inputs. This hierarchy prioritized the inputs into three broad levels as follows: Level 1: Quoted prices in active markets for identical instruments; Level 2: Other significant observable inputs (including quoted prices in active markets for similar instruments); and Level 3: Significant unobservable inputs (including assumptions in determining the fair value of certain investments). The Company’s cash and cash equivalents, restricted cash, short-term investments, accounts receivable, accounts payable and accrued liabilities approximate their fair value due to their short maturities. Management believes that its term loan bears interest at the prevailing market rates for instruments with similar characteristics; accordingly, the carrying value of this instrument approximates its fair value. Money market funds are highly liquid investments and are actively traded. The pricing information on the Company’s money market funds are readily available and can be independently validated as of the measurement date. This approach results in the classification of these securities as Level 1 of the fair value hierarchy. The Company has issued redeemable convertible preferred stock warrants and estimated the fair value of these warrants using the Black-Scholes option pricing model, which is considered to be a Level 3 fair value measurement. The assumptions were based on the individual characteristics of the warrants on the valuation date, as well as assumptions for future financings, expected volatility, expected life, yield, and risk-free interest rate. Effective on the date of the IPO, the redeemable convertible preferred stock warrants were considered to be indexed to the Company’s stock, and accordingly, the fair value of redeemable convertible preferred stock warrant liability was remeasured immediately prior to the IPO (See Note 4). Accounts Receivable, Net Accounts receivable are recorded at invoice value, net of any allowance for doubtful accounts. Estimates of the allowance for doubtful accounts are determined based on existing contractual payment terms, historical payment patterns of customers and individual customer circumstances. The allowance for doubtful accounts was not significant as of December 31, 2020 and 2019, respectively. Inventories Inventories are stated at the lower of cost or net realizable value. Cost is determined using the standard cost method, which approximates actual costs as determined on a first-in, first-out basis. The carrying value of inventories is reduced for any difference between cost and net realizable value of inventories that is determined to be obsolete or unmarketable, based upon assumptions about future demand and market conditions. The Company also reviews its inventory value to determine if it reflects the lower of cost or net realizable value based on factors such as inventory items sold at negative gross margins and purchase commitments. Adjustments to the value of inventory establish a new cost basis and are considered permanent even if circumstances later suggest that increased carrying amounts are recoverable. If demand is higher than expected, the Company may sell inventory that had previously been written down. Costs associated with the write-down of inventory are recorded to cost of revenue on the Company’s statements of operations. Property and Equipment, Net Property and equipment, net is stated at cost, net of accumulated depreciation. Depreciation is generally computed using the straight-line method based on the estimated useful lives of the assets, which is generally two to five years. Certain Tablo consoles under operating leases are depreciated using the accelerated method. Leasehold improvements are amortized using the straight-line method over the shorter of the assets estimated useful lives or the remaining term of the lease. Maintenance and repairs are charged to expense as incurred. Significant improvements that substantially enhance the useful life of an asset are capitalized and depreciated. When assets are retired or disposed of, the cost together with related accumulated depreciation is removed from the balance sheet and any resulting gain or loss is reflected in the Company’s statements of operations in the period realized. Impairment for Long-Lived Assets Long-lived assets, such as property and equipment 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 or asset group to be tested for possible impairment, the Company first compares undiscounted cash flows expected to be generated by that asset or asset group to its carrying value. If the carrying value of the long-lived asset or asset group is not recoverable on an undiscounted cash flow basis, an impairment is recognized to the extent that the carrying value 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. There were no such impairment losses as of December 31, 2020 and 2019. Leases The Company determines if an arrangement is a lease at inception by assessing whether the arrangement contains an identified asset and whether it has the right to control the identified asset. Right-of-use (ROU) assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Lease liabilities are recognized at the lease commencement date based on the present value of future lease payments over the lease term. ROU assets are based on the measurement of the lease liability and also include any lease payments made prior to or on lease commencement and exclude lease incentives and initial direct costs incurred, as applicable. As the implicit rate in the Company’s leases is generally unknown, the Company uses its incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. The lease terms may include options to extend or terminate the lease when the Company is reasonably certain it will exercise such options. Lease costs for the Company’s operating leases are recognized on a straight-line basis over the reasonably assured lease term. Variable lease payments include lease operating expenses. The Company has elected to not separate lease and non-lease components for any leases within its existing classes of assets and, as a result, accounts for any lease and non-lease components as a single lease component. The Company has also elected to not apply the recognition requirement to any leases within its existing classes of assets with a term of 12 months or less and does not include an option to purchase the underlying asset that the Company is reasonably certain to exercise. Accrued Warranty Liability The Company generally provides a one-year warranty for defective parts and workmanship on its Tablo consoles, commencing upon the transfer of title and risk of loss to the customer. The Company accrues the estimated cost of product warranties when it invoices the customer, based on historical experience and expected results. Should actual product failure rates and material usage costs differ from these estimates, revisions to the estimated warranty liability would be required. The Company periodically assesses the adequacy of its recorded product warranty liabilities and adjusts the balance as required. Warranty expense is recorded as a component of cost of product revenue in the statements of operations. Contract Liabilities - Deferred Revenue The timing of revenue recognition may differ from the timing of invoicing to customers. The Company records deferred revenue when revenue is recognized subsequent to invoicing. For multi-year service agreements, the Company generally invoices customers annually at the beginning of each annual coverage period. Deferred revenue that will be recognized during the 12 months following the balance sheet date is recorded as the current portion of deferred revenue and the remaining portion is recorded as noncurrent. Redeemable Convertible Preferred Stock Warrant Liability The Company has accounted for its freestanding warrants to purchase shares of the Company’s redeemable convertible preferred stock as liabilities at fair value upon issuance primarily because the shares underlying the warrants contained contingent redemption features outside of the Company’s control. The warrants were subject to re-measurement at each balance sheet date and any change in fair value was recognized in the statements of operations as the change in fair value of redeemable convertible preferred stock warrant liability. The carrying value of the warrants would continue to be adjusted until these instruments are exercised, expire or convert into warrants to purchase shares of the Company’s common stock upon the completion of a liquidation event, including the completion of the IPO, which occurred on September 15, 2020. Upon the closing of the IPO, the liabilities were reclassified to additional paid-in capital, a component of Stockholders’ equity (deficit). The Company estimated the fair value of these liabilities using the Black-Scholes option pricing model and assumptions that were based on the individual characteristics of the warrants on the valuation date, as well as assumptions for future financings, expected volatility, expected life, yield, and risk-free interest rate. Defined Contribution Plan The Company has a defined contribution retirement savings plan under Section 401(k) of the Internal Revenue Code. This plan allows eligible employees to defer a portion of their annual compensation on a pre-tax basis. The Company is authorized to make matching contributions but has not made such contributions for the years ended December 31, 2020, 2019 and 2018. Revenue The Company’s revenue is generated primarily from the sale of its products and services. Product revenue consists primarily of sales of the Tablo console and related consumables, including Tablo cartridges, used in treatment delivery. Service and other revenue consists primarily of revenue generated from consoles service contracts and other revenue from shipping and handling charged to customers. The Company considers each product and each service contract to be a distinct performance obligation. Revenue is recognized when a performance obligation is satisfied, which occurs when control of the promised products or services is transferred to the customer in an amount that reflects the consideration the Company expects to receive in exchange for those products or services. Revenue from product sales is recognized at a point in time when management has determined that control has transferred to the customer, which is generally when legal title has transferred to the customer. Revenue from service contracts is recognized as the output of the service is transferred to the customer over time, typically evenly over the contract term. Revenue is recognized net of allowances for returns and any taxes collected from customers, which are subsequently remitted to governmental authorities. The Company’s contracts with customers often include promises to transfer multiple products and services to a customer. Determining whether products and services are considered distinct performance obligations that should be accounted for separately versus together may require significant judgment. Judgment is also required to determine the stand-alone selling price (SSP) for each distinct performance obligation. The Company uses an observable price to estimate SSP for items that are sold separately, including customer support agreements. In instances where SSP is not directly observable, such as when the Company does not sell the product or service separately, the Company determines the SSP using information that may include market conditions and other observable inputs. The Company may offer additional goods or services to customers at the inception of customer contracts at prices not at SSP. This is considered a material right and an additional performance obligation of the contract. SSP is assigned based on the estimated value of the material right. Costs associated with product sales include commissions. The Company applies the practical expedient to expense the commissions as incurred as the expected amortization period is one year or less. Commissions are recorded as sales and marketing expenses in the statements of operations. Operating Lease Arrangements The Company enters into operating lease arrangements that contain both lease and non-lease elements. The lease element includes Tablo consoles, while non-lease elements include consumables, services and training. Revenue related to such arrangements is allocated to lease and non-lease elements based on their relative SSP. Revenue for the lease element, net of any taxes collected from customers, is recognized on a straight-line basis as product revenue over the lease term, generally three months to one year, in the statements of operations. The costs of the leased Tablo consoles are included in property and equipment, net in the balance sheets and amortized to cost of product revenue. Shipping and Handling Costs Shipping and handling charged to customers are recorded as revenue. Shipping and handling costs are expensed as incurred and are included in sales and marketing expenses. Stock-Based Compensation Expense Stock-based compensation expense relates to stock options with a service condition, stock options with performance and market-based vesting conditions, stock purchase rights under our Employee Stock Purchase Plan (ESPP), restricted stock units (RSUs) and performance stock units (PSUs). Stock-based compensation expense for the Company’s stock-based awards is based on their grant date fair value. Service-based options initially granted to an optionee generally vest at a rate of 25% on the first anniversary of the original vesting date, with the balance vesting monthly over the remaining three years. Any subsequent follow-on options granted to the optionee generally vest monthly over four years. The fair value of stock options with a service condition and stock purchase rights under the ESPP on the grant date is estimated using the Black-Scholes option-pricing model. The fair value of these awards is recognized as compensation expense on a straight-line basis over the requisite service period in which the awards are expected to vest and forfeitures are recognized as they occur. The Black-Scholes model considers several variables and assumptions in estimating the fair value of service-based stock options and stock purchase rights under the ESPP. These variables include the per share fair value of the underlying common stock, exercise price, expected term, risk-free interest rate, expected annual dividend yield and expected stock price volatility over the expected term. For all service-based stock options granted, the Company calculates the expected term using the simplified method for “plain vanilla” stock option awards. The Company had no publicly available stock price information prior to the IPO and limited available stock price information subsequent to the IPO; therefore, the Company has used the historical volatility of the stock price of similar publicly traded peer companies. The risk-free interest rate is based on the yield available on U.S. Treasury zero-coupon issues similar in duration to the expected term of the equity-settled award. For stock options with performance and market-based vesting conditions, stock-based compensation expense is recognized when it is considered probably that the performance vesting condition will be satisfied. Prior to the IPO in September 2020, the Company had not recognized any stock-based compensation expense as the satisfaction of the performance condition was not considered probable. Upon the closing of the IPO, the Company recorded a cumulative stock-based compensation expense using the accelerated attribution method as the performance condition was satisfied. Stock-based compensation expense related to these options is not reversed if the achievement of the market condition does not occur. The fair value of these stock options is estimated using the Monte Carlo approach. RSUs initially granted to an optionee generally vest at a rate of 25% on the first anniversary of the original vesting date, with the balance vesting quarterly over the remaining three years. The fair value of RSUs and PSUs is based on the market price of the Company’s common stock on the date of grant. The determination of the stock-based compensation expense related to PSUs to be recognized in the Company’s statements of operations requires the use of certain estimates and assumptions. At each reported period, the Company reassesses the probability of the achievement of corporate performance goals to estimate the number of shares to be released. Any increase or decrease in stock-based compensation expense resulting from an adjustment in the estimated shares to be released is treated as accumulative catch-up in the period of adjustment. If any of the assumptions or estimates used change significantly, stock-based compensation expense may differ materially from what the Company has recorded in the current period. Research and Development The Company expenses all research and development costs as incurred. These expenses include the costs of proprietary research and development efforts, quality engineering, clinical studies and trials and regulatory affairs. Costs include personnel and related costs, supplies, testing, contract and other outside service fees, depreciation expense and allocated costs including facilities and information technology. Advertising Costs Advertising costs are expensed as incurred. The advertising costs for years ended December 31, 2020, 2019 and 2018 were not significant. Income Taxes The Company accounts for income taxes under the asset and liability method. Under this method, deferred tax assets and liabilities are determined based on differences between financial reporting and tax reporting bases of assets and liabilities and remeasured using enacted tax rates and laws that are expected to be in effect when the differences are expected to reverse. Realization of deferred tax assets is dependent upon future earnings, the timing and amount of which are uncertain. The Company utilizes a two-step approach to recognize and measure uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained upon tax authority examination, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon ultimate settlement. The Company includes any penalties and interest expense related to income taxes as a component of other expense, net, as necessary. Net Loss per Share Attributable to Common Stockholders Basic net loss per share attributable to common stockholders is calculated by dividing the net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding for the period, without consideration for potential dilutive securities. Diluted net loss per share is computed by dividing the net loss by the weighted-average number of common shares and common share equivalents of potentially dilutive securities outstanding for the period. For purposes of the diluted net loss per share calculation, redeemable convertible preferred stock, awards under the Company’s equity compensation plan and warrants are considered to be potentially dilutive securities. For periods in which the Company reports net losses, basic net loss per share attributable to common stockholders is the same as diluted net loss per share attributable to common stockholders because the effects of potentially dilutive securities are antidilutive. Recently Adopted Accounting Pronouncements In August 2018, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement (ASU 2018-13). The amendments on changes in unrealized gains and losses recognized in other comprehensive income categorized within Level 3, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty should be applied prospectively in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. The Company adopted ASU 2018-13 as of January 1, 2020, which did not have a material impact on its financial statements. Recently Issued Accounting Pronouncements Not Yet Adopted In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326) Measurement of Credit Losses on Financial Instruments (ASU 2016-13), which requires an entity to utilize a new impairment model known as the current expected credit loss (CECL) model to estimate its lifetime “expected credit loss” and record an allowance that, when deducted from the amortized cost basis of the financial assets and certain other instruments, including but not limited to available-for-sale debt securities. Credit losses relating to available-for-sale debt securities will be recorded through an allowance for credit losses rather than as a direct write-down to the security. ASU 2016-13 requires a cumulative effect adjustment to the balance sheet as of the beginning of the first reporting period in which the guidance is effective. In November 2019, the FASB issued ASU 2019-10, Financial Instruments—Credit Losses (Topic 326), Derivatives and Hedging (Topic 815) and Leases (Topic 842): Effective Dates , which defers the effective date of ASU 2016-13 to fiscal years beginning after December 15, 2022 for all entities except SEC reporting companies that are not smaller reporting companies. ASU 2016-13 will be effective for the Company beginning January 1, 2023. The Company is currently evaluating the impact of the adoption of ASU 2016-13 on its financial statements. In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740) , which simplifies the accounting for income taxes, primarily by eliminating certain exceptions to ASC 740. This standard is effective for fiscal periods beginning after December 15, 2021. The Company is currently evaluating this standard and the impact it may have on its financial statements. |

There was no such lease revenue for the year ended December 31, 2018. The maturity of the Company’s operating leases as of December 31, 2020 was as follows (in thousands): Years Ending December 31: 2021 $ 4,431 2022 1,699 Total minimum lease payments 6,130 Performance Obligations As of December 31, 2020, the aggregate amount of the transaction price allocated to the remaining performance obligations related to customer service contracts that are unsatisfied or partially unsatisfied was $3.8 million, which is recorded as deferred revenue on the Company’s balance sheet. Of that amount, $3.2 million will be recognized as revenue during the year ended December 31, 2021 and approximately $0.6 million thereafter. Contract Liabilities The contract liabilities consist of deferred revenue which represents payments received in advance of revenue recognition related to console service agreements and for prepayments for products or services yet to be delivered. Revenue under these agreements is recognized over the related service period. The following table summarizes the Company’s contract liabilities (in thousands): December 31, 2020 2019 Deferred revenue, current $ 3,201 $ 883 Deferred revenue, noncurrent 570 134 Total deferred revenue $ 3,771 $ 1,017 During the year ended December 31, 2020, 2019 and 2018, the Company recognized $0.9 million, $0.3 million, and $0.3 million of revenue, respectively, that was included in the deferred revenue balance at the beginning of the period. |

Fair Value Measurements The following tables summarize the Company’s financial assets and liabilities measured at fair value on a recurring basis by level within the fair value hierarchy (in thousands): December 31, 2020 Valuation Hierarchy Amortized Costs Gross Unrealized Holding Gains Gross Unrealized Holding Losses Aggregate Fair Value Assets: Cash equivalents: Money market funds Level 1 $ 56,056 $ — $ — $ 56,056 Short-term investments: U.S. Treasury securities Level 1 14,999 1 — 15,000 Corporate debt Level 2 4,898 — — 4,898 Total assets $ 75,953 $ 1 $ — $ 75,954 December 31, 2019 Valuation Hierarchy Amortized Costs Gross Unrealized Holding Gains Gross Unrealized Holding Losses Aggregate Fair Value Assets: Cash equivalents: Money market funds Level 1 $ 29,761 $ — $ — $ 29,761 Commercial paper Level 2 2,299 — — 2,299 Short-term investments: Commercial paper Level 2 10,972 — — 10,972 Corporate debt Level 2 17,357 19 — 17,376 Asset-backed securities Level 2 4,801 3 — 4,804 Total assets $ 65,190 $ 22 $ — $ 65,212 Liabilities: Redeemable convertible preferred stock warrant liability Level 3 $ 4,285 $ — $ — $ 4,285 Total liabilities $ 4,285 $ — $ — $ 4,285 The Company’s Level 2 securities are valued using third-party pricing sources. The pricing services utilize industry standard valuation models, including both income and market-based approaches, for which all significant inputs are observable, either directly or indirectly, to estimate fair value. These inputs include reported trades of and broker/dealer quotes on the same or similar securities, issuer credit spreads, benchmark securities, prepayment/default projections based on historical data and other observable inputs. The Company validates the prices provided by its third-party pricing services by understanding the models used, obtaining market values from other pricing sources and confirming those securities traded in active markets. As of December 31, 2020, the remaining contractual maturities for available-for-sale securities were less than one year. Impairment assessments are made at the individual security level each reporting period. When the fair value of an available-for-sale security is less than its cost at the balance sheet date, a determination is made as to whether the impairment is other-than-temporary and, if it is other-than-temporary, an impairment loss is recognized in earnings equal to the difference between the investment’s amortized cost and fair value at such date. As of December 31, 2020 and December 31, 2019, none of the Company’s available-for-sale securities were in an unrealized loss position. Redeemable Convertible Preferred Stock Warrant Liability The valuation of the Company’s redeemable convertible preferred stock warrant liability contained unobservable inputs that reflected the Company’s own assumptions for which there was little, if any, market activity at the measurement date. Accordingly, the Company’s redeemable convertible preferred stock warrant liability was measured at fair value on a recurring basis using unobservable inputs and were classified as Level 3 inputs, and any change in fair value of the redeemable convertible preferred stock warrant liability was recognized in the statements of operations. Effective on the date of the IPO, the redeemable convertible preferred stock warrants were considered to be indexed to the Company’s stock and now meet the criteria to be classified in equity. The Company remeasured the warrants immediately prior to the IPO. The fair value of the Series A redeemable convertible preferred stock warrants which were converted into common stock warrants was determined using the Series B and C determined the entire redeemable convertible preferred stock warrants liability was reclassified to additional paid-in capital. The fair value of the warrants, prior to the IPO, was determined using the Black-Scholes option pricing model and the following assumptions: Years Ended December 31, 2020 2019 2018 Fair value of shares of redeemable convertible preferred stock $1.39 – $27.00 $1.36 – $2.40 $2.05 – $3.25 Expected term (in years) 3.24 – 7.25 3.74 – 7.50 4.74 – 8.50 Expected volatility 53.7% – 57.2% 48.1% – 50.0% 48.8% – 50.1% Risk-free interest rate 0.18% – 1.83% 1.76% – 1.83% 2.51% – 2.59% Dividend yield 0% 0% 0% The change in fair value of the redeemable convertible preferred stock warrant liability was as follows (in thousands): Years Ended December 31, 2020 2019 2018 Beginning balance $ 4,285 $ 8,085 $ 7,823 Change in fair value 93 (3,800 ) 262 Conversion of Series A redeemable convertible preferred stock warrants to common stock warrants upon the closing of the IPO (1,252 ) — — Reclassified to additional paid-in capital (3,126 ) — — Ending balance $ — $ 4,285 $ 8,085 |

The Perceptive Term Loans bore interest at a rate of 8.55%, plus the greater of the three-month London Inter-bank Offered Rate (LIBOR) and 2.00%. In July 2020, the Company used the SVB Term Loan (see below) to repay in full all amounts due under the Perceptive Term Loan and cash on hand to pay $1.2 million in early prepayment, accrued interest and exit fees. The repayment of the Perceptive Term Loan was accounted for as a debt extinguishment, which resulted in a loss on extinguishment of $1.6 million recorded in the statements of operations for the year ended December 31, 2020. SVB Loan and Security Agreement On July 2, 2020, the Company entered into a senior secured term loan facility with Silicon Valley Bank (SVB) (the SVB Loan and Security Agreement), which provides for a $30.0 million term loan (the SVB Term Loan). The SVB Term Loan matures on November 1, 2025. Payments under the SVB Term Loan are for interest only through May 2023, and then 30 monthly principal and interest payments from June 2023 until maturity. The SVB Term Loan bears interest at the greater of (A) 0.5% above the Prime Rate as reported in the Wall Street Journal and (B) 3.75% (3.75% as of December 31, 2020). The Company is obligated to maintain a restricted cash balance greater or equal to the outstanding principal balance of $30.0 million of the SVB Term Loan. There is also a final payment fee equal to 6.75% of the original principal amount of the SVB Term Loan, or approximately $2.0 million, due at maturity (or any earlier date of optional pre-payment or acceleration of principal due to an event of default). Such fee is being accreted to interest expense using the effective interest method with the offset recorded in noncurrent accrued interest. The Company may, at its option, prepay the SVB Term Loan in full, subject to an additional prepayment fee ranging between 1% and 3% of the outstanding principal amount of the SVB Term Loan. In the event of default or change in control, all unpaid principal and all accrued and unpaid interest amounts (if any) become immediately due and payable including the prepayment fee. Events of default include, but are not limited to, a payment default, a material adverse change, and insolvency. The SVB Term Loan is secured by substantially all of the Company’s assets, including all of the capital stock held by the Company, if any (subject to a 65% limitation on pledges of capital stock of foreign subsidiaries), subject to certain exceptions. The SVB Loan and Security Agreement contains customary representations, warranties, affirmative covenants and also contains certain restrictive covenants. Debt issuance costs paid directly to SVB and other debt issuance costs amounting to $0.4 million were accounted for as discounts on the SVB Term Loan. These debt discounts, along with the final payment fee, are being amortized over the term of the SVB Term Loan using the effective interest rate method. As of December 31, 2020, the unamortized debt discount was $0.3 million, which is recorded as a direct deduction from the SVB Term Loan on the balance sheets. Aggregate annual payments due on the SVB Term Loan as of December 31, 2020 were as follows (in thousands): Years Ending December 31: 2021 $ 1,141 2022 1,141 2023 8,073 2024 12,667 2025 13,233 Total future payments 36,255 Less: amount representing interest (4,230 ) Less: final payment (2,025 ) Total term loan 30,000 Less: unamortized debt discount (326 ) Total term loan, net of debt discount 29,674 |

The total intrinsic value of options exercised during the years ended December 31, 2020, 2019 and 2018 was $8.2 million, $0.2 million and $0.1 million, respectively. The intrinsic value is the difference between the estimated fair value of the Company’s common stock at the time of exercise and the exercise price of the stock option.

Employees Stock Purchase Plan (ESPP) In September 2020, the Company adopted the Employee Stock Purchase Plan (ESPP). The Company has initially reserved 687,000 shares of common stock for purchase under the ESPP. In addition, the number of shares of common stock available for issuance under the ESPP will automatically increase on the first day of each fiscal year, commencing January 2021 and continuing until (and including) the fiscal year ending December 31, 2030, with such annual increase equal to the lesser of (i) 687,000 shares, (ii) 1% of the number of common stock issued and outstanding on December 31 of the immediately preceding fiscal year, and (iii) an amount determined by the Company’s board of directors. Subject to any limitations contained therein, the ESPP allows eligible participants to contribute, through payroll deductions, up to 15% of their eligible compensation to purchase the Company’s common stock at a purchase price equal to 85% of the fair market value of the common stock on the first day of the offering period or purchase date, whichever is lower.

The fair value of the stock purchase rights under the ESPP is estimated using the Black-Scholes option pricing model. For the year ended December 31, 2020, the grant date fair value was $8.00 and estimated using the following assumptions Expected term (in years) 0.42 Expected volatility 57.0% Risk-free interest rate 0.12% Dividend yield 0% The ESPP commenced in September 2020.

Income Taxes | 10. Income Taxes The provision for income taxes was zero, $20,000 and $25,000 for the years ended December 31, 2020, 2019 and 2018, respectively. The Company has incurred net operating losses for all periods presented. The Company has not reflected any benefit of such net operating loss carryforwards in the financial statements. The Company has established a full valuation allowance against its deferred tax assets due to the uncertainty surrounding the realization of such assets. The effective tax rate of the provision for income taxes differs from the federal statutory rate as follows: Years Ended December 31, 2020 2019 2018 Federal statutory income tax rate 21.0 % 21.0 % 21.0 % State taxes 4.3 7.8 4.9 Change in valuation allowance (23.4 ) (28.5 ) (27.2 ) Federal and state tax credits 0.5 0.9 2.0 Stock based compensation (0.6 ) — — Non-deductible permanent expenses (0.4 ) — — Effect of deferred tax adjustment (1.4 ) — — Other — (1.2 ) (0.7 ) — % — % — % Deferred Tax Assets The major components of deferred tax assets were as follows as of the dates indicated (in thousands): December 31, 2020 2019 Deferred tax assets: Net operating loss carryforwards $ 76,838 $ 56,127 Tax credits 10,039 8,777 Accrual and reserves 2,392 1,675 Tangible and intangible assets 19,090 15,553 Stock-based compensation 2,843 733 Gross deferred tax assets 111,202 82,865 Valuation allowance (111,202 ) (82,865 ) Net deferred tax assets $ — $ — Realization of the deferred tax assets is dependent upon future taxable income, if any, the amount and timing of which are uncertain. The Company has established a valuation allowance to offset deferred tax assets as of December 31, 2020 and 2019 due to the uncertainty of realizing future tax benefits from its net operating loss carryforwards and other deferred tax assets. The valuation allowance increased by $28.3 million, $24.0 million and $13.6 million during the years ended December 31, 2020, 2019 and 2018, respectively. Net Operating Loss and Tax Credit Carryforwards As of December 31, 2020, the Company had a net operating loss carryforward for federal income tax purposes of $301.3 million. Federal net operating losses of $173.5 million incurred after 2017 do not expire. The remaining $127.8 million of federal net operating loss carryforward will begin to expire in 2024 and continue to expire through 2037. The Company had a total state net operating loss carryforward of $174.0 million. State net operating losses of $30.9 million do not expire. The remaining state net operating loss carryforward of $143.1 million will begin to expire in 2021 and continue to expire through 2040. The Company had federal research and development credits of $5.8 million, which will begin to expire in 2030 and state research and development credits of $4.3 million which have no expiration date. These tax credits are subject to the same limitations discussed above. Federal and state laws impose substantial restrictions on the utilization of net operating loss and tax credit carryforwards in the event of an ownership change for tax purposes, as defined in Section 382 of the Internal Revenue Code. As a result of such ownership changes, the Company’s ability to realize the potential future benefit of tax losses and tax credits that existed at the time of the ownership change may be significantly reduced. The Company’s deferred tax asset and related valuation allowance would be reduced, as a result. The Company has not performed a Section 382 study to determine the amount of reduction, if any. Unrecognized tax benefits at December 31, 2020 have been recorded as an offset to federal and state research and development credit carryforwards. Unrecognized Tax Benefits A reconciliation of the total unrecognized tax benefits for the year ended December 31, 2020 was as follows (in thousands): Balance, beginning of year $ 1,020 Decrease related to current year positions — Increase related to current year positions 562 Balance, end of year $ 1,582 The Company does not have any material accrued interest or penalties associated with unrecognized tax benefits. The Company does not believe it is reasonably possible that its unrecognized tax benefits will significantly change within the next twelve months. The Company files income tax returns in the United States and various states. The Company is not currently under examination by income tax authorities in federal, state or other jurisdictions. All tax returns remain open for examination by federal and state authorities for three and four years, respectively, from the date of utilization of any net operating loss or credits. |

Summary of Significant Accoun_2
Summary of Significant Accounting Policies (Policies) | 12 Months Ended |

Accounting Policies [Abstract] | |
Basis of Presentation | Basis of Presentation The financial statements have been prepared in accordance with U.S. generally accepted accounting principles (U.S. GAAP). All share amounts disclosed in the notes to the financial statements are rounded to the nearest thousand except for per share amounts. |
Use of Estimates | Use of Estimates The preparation of the financial statements in conformity with U.S. GAAP requires management to make judgments, estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenue and expenses. These judgments, estimates and assumptions are used for, but not limited to, revenue recognition, allowance for doubtful accounts, inventory valuation and write-downs, warranty obligations, the fair value of common stock and redeemable convertible preferred stock, the fair value of stock options, the fair value of the redeemable convertible preferred stock warrant liability, valuation of investments, recoverability of the Company’s net deferred tax assets and the related valuation allowance, and certain accrued expenses. The Company evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors and adjusts those estimates and assumptions when facts and circumstances dictate. Actual results may differ from those estimates under different assumptions or conditions and the differences may be material. |
Segment | Segment The Company operates as a single operating segment. The Company’s chief operating decision maker, its Chief Executive Officer, reviews financial information on an aggregate basis for the purposes of allocating resources and evaluating financial performance. The Company’s primary operation is in the United States and it has derived its revenue from sales to customers in the United States. The Company has operated a manufacturing facility in Mexico since 2020. T he Company's long-lived tangible assets, as well as the Company's operating lease right-of-use assets recognized on the balance sheets, located in Mexico were $6.0 million as of December 31, 2020. |
Cash, Cash Equivalents and Restricted Cash | Cash, Cash Equivalents and Restricted Cash As of December 31, 2020, the restricted cash balance of $33.3 million primarily relates to contractual obligations under the SVB Loan and Security Agreement (see Note 7) and collateral for the building leases in San Jose, CA and Tijuana, Mexico. The restricted cash balance of $0.7 million as of December 31, 2019 relates to collateral for the building leases. The Company considers all highly liquid investments purchased with an original maturity of three months or less at the date of purchase to be cash equivalents. As of December 31, 2020 and 2019, the Company’s cash equivalents were held in institutions in the United States and include deposits in a money market fund which were unrestricted as to withdrawal or use. The following table provides a reconciliation of cash, cash equivalents and restricted cash that sum to the total of the amounts shown in the statements of cash flows (in thousands): December 31, 2020 2019 Cash and cash equivalents $ 294,972 $ 36,926 Restricted cash 33,311 743 Total cash, cash equivalents and restricted cash $ 328,283 $ 37,669 |
Short-Term Investments | Short-Term Investments Short-term investments have been classified as available-for-sale and are carried at estimated fair value as determined based upon quoted market prices or pricing models for similar securities. The Company determines the appropriate classification of its investments in debt securities at the time of purchase. Available-for-sale securities with original maturities beyond three months at the date of purchase are classified as current based on their availability for use in current operations. The Company’s investment securities are recorded at fair value based on the fair value hierarchy. Money market funds and U.S. Treasury securities are classified within Level 1 of the fair value hierarchy. Commercial paper, corporate debt and asset-backed securities are within Level 2 of the fair value hierarchy. Unrealized gains and losses, deemed temporary in nature, are reported as a separate component of accumulated other comprehensive income (loss). A decline in the fair value of any security below cost that is deemed other than temporary results in a charge to earnings and the corresponding establishment of a new cost basis for the security. Premiums (discounts) are amortized (accreted) over the life of the related security as an adjustment to yield using the straight-line interest method. Dividend and interest income are recognized when earned. Realized gains and losses are included in earnings and are derived using the specific identification method for determining the cost of securities sold. |
Concentration of Credit Risk | Concentration of Credit Risk Financial instruments that potentially subject the Company to a concentration of credit risk consist of cash and cash equivalents, restricted cash, short-term investments and accounts receivable. Substantially all the Company’s cash and cash equivalents, restricted cash and investments are held at one financial institution in the United States that management believes is of high credit quality. Such deposits may, at times, exceed federally insured limits or may not be covered by deposit insurance at all. The Company has not experienced any credit losses on its cash and cash equivalents, restricted cash or short-term investments through December 31, 2020. For the year ended December 31, 2020, three customers accounted for 22%, 19% and 16% of revenues, respectively. One customer accounted for 11% of revenues for the year ended December 31, 2019. Accounts receivable are unsecured and the Company does not require collateral; however, the Company does assess the collectability of accounts receivable based on a number of factors, including past transaction history with, and the creditworthiness of, the customer. Accordingly, the Company is exposed to credit risk associated with accounts receivable. Two customers accounted for 22% and 16% of accounts receivable, respectively, as of December 31, 2020. Four customers accounted for 22%, 13%, 11% and 10% of accounts receivable, respectively, as of December 31, 2019. To reduce risk, the Company closely monitors the amounts due from its customers and assesses the financial strength of its customers through a variety of methods that include, but are not limited to, engaging directly with customer operations and leadership personnel, visiting customer locations to observe operating activities, and assessing customer longevity and reputation in the marketplace. As a result, the Company believes that its accounts receivable credit risk exposure is limited. |
Fair Value of Financial Instruments | Fair Value of Financial Instruments The Company determines the fair value of an asset or liability based on the assumptions that market participants would use in pricing the asset or liability in an orderly transaction between market participants at the measurement date. The identification of market participant assumptions provides a basis for determining what inputs are to be used for pricing each asset or liability. A fair value hierarchy has been established which gives precedence to fair value measurements calculated using observable inputs over those using unobservable inputs. This hierarchy prioritized the inputs into three broad levels as follows: Level 1: Quoted prices in active markets for identical instruments; Level 2: Other significant observable inputs (including quoted prices in active markets for similar instruments); and Level 3: Significant unobservable inputs (including assumptions in determining the fair value of certain investments). The Company’s cash and cash equivalents, restricted cash, short-term investments, accounts receivable, accounts payable and accrued liabilities approximate their fair value due to their short maturities. Management believes that its term loan bears interest at the prevailing market rates for instruments with similar characteristics; accordingly, the carrying value of this instrument approximates its fair value. Money market funds are highly liquid investments and are actively traded. The pricing information on the Company’s money market funds are readily available and can be independently validated as of the measurement date. This approach results in the classification of these securities as Level 1 of the fair value hierarchy. The Company has issued redeemable convertible preferred stock warrants and estimated the fair value of these warrants using the Black-Scholes option pricing model, which is considered to be a Level 3 fair value measurement. The assumptions were based on the individual characteristics of the warrants on the valuation date, as well as assumptions for future financings, expected volatility, expected life, yield, and risk-free interest rate. Effective on the date of the IPO, the redeemable convertible preferred stock warrants were considered to be indexed to the Company’s stock, and accordingly, the fair value of redeemable convertible preferred stock warrant liability was remeasured immediately prior to the IPO (See Note 4). |
Accounts Receivable, Net | Accounts Receivable, Net Accounts receivable are recorded at invoice value, net of any allowance for doubtful accounts. Estimates of the allowance for doubtful accounts are determined based on existing contractual payment terms, historical payment patterns of customers and individual customer circumstances. The allowance for doubtful accounts was not significant as of December 31, 2020 and 2019, respectively. |
Inventories | Inventories Inventories are stated at the lower of cost or net realizable value. Cost is determined using the standard cost method, which approximates actual costs as determined on a first-in, first-out basis. The carrying value of inventories is reduced for any difference between cost and net realizable value of inventories that is determined to be obsolete or unmarketable, based upon assumptions about future demand and market conditions. The Company also reviews its inventory value to determine if it reflects the lower of cost or net realizable value based on factors such as inventory items sold at negative gross margins and purchase commitments. Adjustments to the value of inventory establish a new cost basis and are considered permanent even if circumstances later suggest that increased carrying amounts are recoverable. If demand is higher than expected, the Company may sell inventory that had previously been written down. Costs associated with the write-down of inventory are recorded to cost of revenue on the Company’s statements of operations. |
Property and Equipment, Net | Property and Equipment, Net Property and equipment, net is stated at cost, net of accumulated depreciation. Depreciation is generally computed using the straight-line method based on the estimated useful lives of the assets, which is generally two to five years. Certain Tablo consoles under operating leases are depreciated using the accelerated method. Leasehold improvements are amortized using the straight-line method over the shorter of the assets estimated useful lives or the remaining term of the lease. Maintenance and repairs are charged to expense as incurred. Significant improvements that substantially enhance the useful life of an asset are capitalized and depreciated. When assets are retired or disposed of, the cost together with related accumulated depreciation is removed from the balance sheet and any resulting gain or loss is reflected in the Company’s statements of operations in the period realized. |
Impairment for Long-Lived Assets | Impairment for Long-Lived Assets Long-lived assets, such as property and equipment 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 or asset group to be tested for possible impairment, the Company first compares undiscounted cash flows expected to be generated by that asset or asset group to its carrying value. If the carrying value of the long-lived asset or asset group is not recoverable on an undiscounted cash flow basis, an impairment is recognized to the extent that the carrying value 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. There were no such impairment losses as of December 31, 2020 and 2019. |
Leases | Leases The Company determines if an arrangement is a lease at inception by assessing whether the arrangement contains an identified asset and whether it has the right to control the identified asset. Right-of-use (ROU) assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Lease liabilities are recognized at the lease commencement date based on the present value of future lease payments over the lease term. ROU assets are based on the measurement of the lease liability and also include any lease payments made prior to or on lease commencement and exclude lease incentives and initial direct costs incurred, as applicable. As the implicit rate in the Company’s leases is generally unknown, the Company uses its incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. The lease terms may include options to extend or terminate the lease when the Company is reasonably certain it will exercise such options. Lease costs for the Company’s operating leases are recognized on a straight-line basis over the reasonably assured lease term. Variable lease payments include lease operating expenses. The Company has elected to not separate lease and non-lease components for any leases within its existing classes of assets and, as a result, accounts for any lease and non-lease components as a single lease component. The Company has also elected to not apply the recognition requirement to any leases within its existing classes of assets with a term of 12 months or less and does not include an option to purchase the underlying asset that the Company is reasonably certain to exercise. |
Accrued Warranty Liability | Accrued Warranty Liability The Company generally provides a one-year warranty for defective parts and workmanship on its Tablo consoles, commencing upon the transfer of title and risk of loss to the customer. The Company accrues the estimated cost of product warranties when it invoices the customer, based on historical experience and expected results. Should actual product failure rates and material usage costs differ from these estimates, revisions to the estimated warranty liability would be required. The Company periodically assesses the adequacy of its recorded product warranty liabilities and adjusts the balance as required. Warranty expense is recorded as a component of cost of product revenue in the statements of operations. |
Contract Liabilities - Deferred Revenue | Contract Liabilities - Deferred Revenue The timing of revenue recognition may differ from the timing of invoicing to customers. The Company records deferred revenue when revenue is recognized subsequent to invoicing. For multi-year service agreements, the Company generally invoices customers annually at the beginning of each annual coverage period. Deferred revenue that will be recognized during the 12 months following the balance sheet date is recorded as the current portion of deferred revenue and the remaining portion is recorded as noncurrent. |
Redeemable Convertible Preferred Stock Warrant Liability | Redeemable Convertible Preferred Stock Warrant Liability The Company has accounted for its freestanding warrants to purchase shares of the Company’s redeemable convertible preferred stock as liabilities at fair value upon issuance primarily because the shares underlying the warrants contained contingent redemption features outside of the Company’s control. The warrants were subject to re-measurement at each balance sheet date and any change in fair value was recognized in the statements of operations as the change in fair value of redeemable convertible preferred stock warrant liability. The carrying value of the warrants would continue to be adjusted until these instruments are exercised, expire or convert into warrants to purchase shares of the Company’s common stock upon the completion of a liquidation event, including the completion of the IPO, which occurred on September 15, 2020. Upon the closing of the IPO, the liabilities were reclassified to additional paid-in capital, a component of Stockholders’ equity (deficit). The Company estimated the fair value of these liabilities using the Black-Scholes option pricing model and assumptions that were based on the individual characteristics of the warrants on the valuation date, as well as assumptions for future financings, expected volatility, expected life, yield, and risk-free interest rate. |
Defined Contribution Plan | Defined Contribution Plan The Company has a defined contribution retirement savings plan under Section 401(k) of the Internal Revenue Code. This plan allows eligible employees to defer a portion of their annual compensation on a pre-tax basis. The Company is authorized to make matching contributions but has not made such contributions for the years ended December 31, 2020, 2019 and 2018. |
Revenue | Revenue The Company’s revenue is generated primarily from the sale of its products and services. Product revenue consists primarily of sales of the Tablo console and related consumables, including Tablo cartridges, used in treatment delivery. Service and other revenue consists primarily of revenue generated from consoles service contracts and other revenue from shipping and handling charged to customers. The Company considers each product and each service contract to be a distinct performance obligation. Revenue is recognized when a performance obligation is satisfied, which occurs when control of the promised products or services is transferred to the customer in an amount that reflects the consideration the Company expects to receive in exchange for those products or services. Revenue from product sales is recognized at a point in time when management has determined that control has transferred to the customer, which is generally when legal title has transferred to the customer. Revenue from service contracts is recognized as the output of the service is transferred to the customer over time, typically evenly over the contract term. Revenue is recognized net of allowances for returns and any taxes collected from customers, which are subsequently remitted to governmental authorities. The Company’s contracts with customers often include promises to transfer multiple products and services to a customer. Determining whether products and services are considered distinct performance obligations that should be accounted for separately versus together may require significant judgment. Judgment is also required to determine the stand-alone selling price (SSP) for each distinct performance obligation. The Company uses an observable price to estimate SSP for items that are sold separately, including customer support agreements. In instances where SSP is not directly observable, such as when the Company does not sell the product or service separately, the Company determines the SSP using information that may include market conditions and other observable inputs. The Company may offer additional goods or services to customers at the inception of customer contracts at prices not at SSP. This is considered a material right and an additional performance obligation of the contract. SSP is assigned based on the estimated value of the material right. Costs associated with product sales include commissions. The Company applies the practical expedient to expense the commissions as incurred as the expected amortization period is one year or less. Commissions are recorded as sales and marketing expenses in the statements of operations. Operating Lease Arrangements The Company enters into operating lease arrangements that contain both lease and non-lease elements. The lease element includes Tablo consoles, while non-lease elements include consumables, services and training. Revenue related to such arrangements is allocated to lease and non-lease elements based on their relative SSP. Revenue for the lease element, net of any taxes collected from customers, is recognized on a straight-line basis as product revenue over the lease term, generally three months to one year, in the statements of operations. The costs of the leased Tablo consoles are included in property and equipment, net in the balance sheets and amortized to cost of product revenue. Shipping and Handling Costs Shipping and handling charged to customers are recorded as revenue. Shipping and handling costs are expensed as incurred and are included in sales and marketing expenses. |
Stock-Based Compensation Expense | Stock-Based Compensation Expense Stock-based compensation expense relates to stock options with a service condition, stock options with performance and market-based vesting conditions, stock purchase rights under our Employee Stock Purchase Plan (ESPP), restricted stock units (RSUs) and performance stock units (PSUs). Stock-based compensation expense for the Company’s stock-based awards is based on their grant date fair value. Service-based options initially granted to an optionee generally vest at a rate of 25% on the first anniversary of the original vesting date, with the balance vesting monthly over the remaining three years. Any subsequent follow-on options granted to the optionee generally vest monthly over four years. The fair value of stock options with a service condition and stock purchase rights under the ESPP on the grant date is estimated using the Black-Scholes option-pricing model. The fair value of these awards is recognized as compensation expense on a straight-line basis over the requisite service period in which the awards are expected to vest and forfeitures are recognized as they occur. The Black-Scholes model considers several variables and assumptions in estimating the fair value of service-based stock options and stock purchase rights under the ESPP. These variables include the per share fair value of the underlying common stock, exercise price, expected term, risk-free interest rate, expected annual dividend yield and expected stock price volatility over the expected term. For all service-based stock options granted, the Company calculates the expected term using the simplified method for “plain vanilla” stock option awards. The Company had no publicly available stock price information prior to the IPO and limited available stock price information subsequent to the IPO; therefore, the Company has used the historical volatility of the stock price of similar publicly traded peer companies. The risk-free interest rate is based on the yield available on U.S. Treasury zero-coupon issues similar in duration to the expected term of the equity-settled award. For stock options with performance and market-based vesting conditions, stock-based compensation expense is recognized when it is considered probably that the performance vesting condition will be satisfied. Prior to the IPO in September 2020, the Company had not recognized any stock-based compensation expense as the satisfaction of the performance condition was not considered probable. Upon the closing of the IPO, the Company recorded a cumulative stock-based compensation expense using the accelerated attribution method as the performance condition was satisfied. Stock-based compensation expense related to these options is not reversed if the achievement of the market condition does not occur. The fair value of these stock options is estimated using the Monte Carlo approach. RSUs initially granted to an optionee generally vest at a rate of 25% on the first anniversary of the original vesting date, with the balance vesting quarterly over the remaining three years. The fair value of RSUs and PSUs is based on the market price of the Company’s common stock on the date of grant. The determination of the stock-based compensation expense related to PSUs to be recognized in the Company’s statements of operations requires the use of certain estimates and assumptions. At each reported period, the Company reassesses the probability of the achievement of corporate performance goals to estimate the number of shares to be released. Any increase or decrease in stock-based compensation expense resulting from an adjustment in the estimated shares to be released is treated as accumulative catch-up in the period of adjustment. If any of the assumptions or estimates used change significantly, stock-based compensation expense may differ materially from what the Company has recorded in the current period. |
Research and Development | Research and Development The Company expenses all research and development costs as incurred. These expenses include the costs of proprietary research and development efforts, quality engineering, clinical studies and trials and regulatory affairs. Costs include personnel and related costs, supplies, testing, contract and other outside service fees, depreciation expense and allocated costs including facilities and information technology. |
Advertising Costs | Advertising Costs Advertising costs are expensed as incurred. The advertising costs for years ended December 31, 2020, 2019 and 2018 were not significant. |
Income Taxes | Income Taxes The Company accounts for income taxes under the asset and liability method. Under this method, deferred tax assets and liabilities are determined based on differences between financial reporting and tax reporting bases of assets and liabilities and remeasured using enacted tax rates and laws that are expected to be in effect when the differences are expected to reverse. Realization of deferred tax assets is dependent upon future earnings, the timing and amount of which are uncertain. The Company utilizes a two-step approach to recognize and measure uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained upon tax authority examination, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon ultimate settlement. The Company includes any penalties and interest expense related to income taxes as a component of other expense, net, as necessary. |
Net Loss Per Share Attributable to Common Stockholders | Net Loss per Share Attributable to Common Stockholders Basic net loss per share attributable to common stockholders is calculated by dividing the net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding for the period, without consideration for potential dilutive securities. Diluted net loss per share is computed by dividing the net loss by the weighted-average number of common shares and common share equivalents of potentially dilutive securities outstanding for the period. For purposes of the diluted net loss per share calculation, redeemable convertible preferred stock, awards under the Company’s equity compensation plan and warrants are considered to be potentially dilutive securities. For periods in which the Company reports net losses, basic net loss per share attributable to common stockholders is the same as diluted net loss per share attributable to common stockholders because the effects of potentially dilutive securities are antidilutive. |
Recently Adopted Accounting Pronouncements and Recently Issued Accounting Pronouncements Not Yet Adopted | Recently Adopted Accounting Pronouncements In August 2018, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement (ASU 2018-13). The amendments on changes in unrealized gains and losses recognized in other comprehensive income categorized within Level 3, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty should be applied prospectively in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. The Company adopted ASU 2018-13 as of January 1, 2020, which did not have a material impact on its financial statements. Recently Issued Accounting Pronouncements Not Yet Adopted In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326) Measurement of Credit Losses on Financial Instruments (ASU 2016-13), which requires an entity to utilize a new impairment model known as the current expected credit loss (CECL) model to estimate its lifetime “expected credit loss” and record an allowance that, when deducted from the amortized cost basis of the financial assets and certain other instruments, including but not limited to available-for-sale debt securities. Credit losses relating to available-for-sale debt securities will be recorded through an allowance for credit losses rather than as a direct write-down to the security. ASU 2016-13 requires a cumulative effect adjustment to the balance sheet as of the beginning of the first reporting period in which the guidance is effective. In November 2019, the FASB issued ASU 2019-10, Financial Instruments—Credit Losses (Topic 326), Derivatives and Hedging (Topic 815) and Leases (Topic 842): Effective Dates , which defers the effective date of ASU 2016-13 to fiscal years beginning after December 15, 2022 for all entities except SEC reporting companies that are not smaller reporting companies. ASU 2016-13 will be effective for the Company beginning January 1, 2023. The Company is currently evaluating the impact of the adoption of ASU 2016-13 on its financial statements. In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740) , which simplifies the accounting for income taxes, primarily by eliminating certain exceptions to ASC 740. This standard is effective for fiscal periods beginning after December 15, 2021. The Company is currently evaluating this standard and the impact it may have on its financial statements. |
