Accounting Policies [Abstract]
Basis of Presentation and Summary of Significant Accounting Policies	Basis of Presentation and Summary of Significant Accounting Policies Basis of Presentation and Consolidation The accompanying condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, these condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020. In the opinion of management, the condensed consolidated financial statements reflect all adjustments, which are normal and recurring in nature, necessary for fair financial statement presentation. All intercompany transactions and balances have been eliminated in consolidation. Use of Estimates The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make judgments, estimates and assumptions that affect the reported amounts of assets, liabilities, equity, revenues and expenses, and related disclosures. The significant estimates made by management include inventory reserves, valuation allowance for deferred tax assets, valuation of warrants, revenue, stock-based compensation expense and other loss contingencies. Management periodically evaluates such estimates and they are adjusted prospectively based upon such periodic evaluation. Actual results could differ from those estimates. Segment Information The Company has determined its operating segments on the same basis that it uses to evaluate its performance internally. The Company has two business activities: (i) manufacturing and distribution of lidar sensors that measure distance using laser light to generate a highly accurate 3D map for automotive mobility applications and (ii) development of ultra-sensitive pixel-based sensors and designing, testing and providing consulting services for non-standard integrated circuits that are essential for systems to meet the requirement of customers. The Company’s operating segments are (i) Autonomy Solutions and (ii) Component Sales. The Company’s chief operating decision maker (“CODM”), its Chief Executive Officer, reviews the operating results of these segments for the purpose of allocating resources and evaluating financial performance. Concentration of Credit Risk Financial instruments that potentially subject the Company to significant concentrations of credit risk, consist primarily of cash and cash equivalents, marketable investments and accounts receivable. A significant portion of the Company’s cash and cash equivalents is held at high-quality domestic financial institutions. Deposits held with the financial institutions may, at times, exceed the amount of insurance provided on such deposits . The Company held cash in foreign entities of $0.5 million and $0.6 million as of March 31, 2021 and December 31, 2020, respectively. The Company’s revenue is derived from customers located in the United States and international markets. The Company mitigates its credit risks by performing ongoing credit evaluations of its customers’ financial conditions and requires advance payment from customers in certain circumstances. The Company generally does not require collateral. Three customers accounted for 28%, 19%, and 18%, respectively, of the Company’s accounts receivable at March 31, 2021 and one customer accounted for 86% of the Company’s accounts receivable at December 31, 2020. Significant Accounting Policies The Company’s significant accounting policies are disclosed in its Annual Report on Form 10-K for the year ended December 31, 2020. Other than the accounting policies discussed below related to equity investments, accounting for Earn-Out shares and in Note 11 related to the adoption of Accounting Standards Codification (“ASC”) 842, Leases , there has been no material change to the Company’s significant accounting policies during the three months ended March 31, 2021. See Note 11 related to the adoption of ASC 842 . Equity Investments The Company’s holds marketable equity investments, over which the Company does not have a controlling interest or significant influence. Marketable equity investments are measured using the quoted prices in active markets with changes recorded in other income (expense), net on the condensed consolidated statement of operations. Recently Adopted Accounting Pronouncements In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) No. 2016-02, Leases (Topic 842) and issued subsequent amendments to the initial guidance in 2017, 2018 and 2019 (collectively “ASC 842”). Under the new guidance, a lessee is required to recognize assets and liabilities for both finance, previously known as capital, and operating leases with lease terms of more than 12 months. The ASU also requires disclosures to help investors and other financial statement users better understand the amount, timing, and uncertainty of cash flows arising from leases. In transition, the Company recognized and measured leases at the beginning of the period of adoption, January 1, 2021, using a modified retrospective approach that included a number of optional practical expedients that the Company elected to apply. See Note 11 for disclosure on the impact of adopting this standard. Recent Accounting Pronouncements Not Yet Effective In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (ASC 326) : Measurement of Credit Losses of Financial Instruments, which, together with subsequent amendments, amends the requirement on the measurement and recognition of expected credit losses for financial assets held. ASU 2016-13 will be effective for the Company beginning January 1, 2023, with early adoption permitted. The Company is currently in the process of evaluating the effects of this pronouncement on the Company’s financial statements and does not expect it to have a material impact on the consolidated financial statements.

Revenue	Revenue Disaggregation of Revenues The Company disaggregates its revenue from contracts with customers by geographic region based on the primary locations where the customer is situated, type of good or service and timing of transfer of goods or services to customers (point-in-time or over time), as it believes it best depicts how the nature, amount, timing and uncertainty of its revenue and cash flows are affected by economic factors. Total revenue based on the disaggregation criteria described above are as follows (in thousands): Three Months Ended March 31, 2021 2020 Revenue % of Revenue Revenue % of Revenue Revenue by primary geographical market: North America $ 2,539 48 % $ 1,085 28 % Asia Pacific 321 6 % 8 — % Europe and Middle East 2,453 46 % 2,779 72 % Total $ 5,313 100 % $ 3,872 100 % Revenue by timing of recognition: Recognized at a point in time $ 2,053 39 % $ 608 16 % Recognized over time 3,260 61 % 3,264 84 % Total $ 5,313 100 % $ 3,872 100 % Revenue by segment: Autonomy Solutions $ 4,336 82 % $ 3,297 85 % Component Sales 977 18 % 575 15 % Total $ 5,313 100 % $ 3,872 100 % Volvo Stock Purchase Warrant In March 2020, the Company issued a stock purchase warrant to Volvo Car Technology Fund AB (“VCTF”) in connection with an engineering services contract. VCTF is entitled to purchase from the Company up to 4,089,280 shares of Class A common stock, at a price of $3.1769 per share. The warrants vest and become exercisable in two tranches based on satisfaction of certain commercial milestones. The fair value of warrants aggregating $2.9 million represent consideration payable to a customer and would be recognized as reduction in revenue consistent with the revenue recognition pattern when these warrants become probable of vesting. The Company’s management determined that the vesting of these warrants was not probable as of March 31, 2021. Contract assets and liabilities Contract assets primarily represent revenues recognized for performance obligations that have been satisfied but for which amounts have not been billed. The Company’s contract assets as of March 31, 2021 and December 31, 2020 were $1.2 million and $0, respectively. Contract liabilities consist of deferred revenue and customer advanced payments. Deferred revenue includes billings in excess of revenue recognized related to product sales and other services revenue and is recognized as revenue when the Company performs under the contract. Customer advanced payments represent required customer payments in advance of product shipments according to customer’s payment term. Customer advance payments are recognized as revenue when control of the performance obligation is transferred to the customer. The Company’s contract liabilities were $0.7 million and $2.3 million as of March 31, 2021 and December 31, 2020, respectively, and were included in accrued and other current liabilities in the condensed consolidated balance sheets. The significant changes in contract liabilities balances consisted of the following (in thousands): March 31, 2021 December 31, 2020 Beginning balance $ 2,284 $ 225 Revenue recognized that was included in the contract liabilities beginning balance (1,667) (225) Increase due to cash received and not recognized as revenue and billings in excess of revenue recognized during the period 37 2,284 Ending balance $ 654 $ 2,284

Fair Value Measurements

Fair Value Measurements	Mar. 31, 2021
Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The Company carries cash equivalents, marketable investments, and Public and Private Warrants. Fair value is based on the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is estimated by applying the following hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement: Level 1 — Observable inputs, which include unadjusted quoted prices in active markets for identical assets or liabilities. Level 2 — Observable inputs other than Level 1 inputs, such as quoted prices 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. Level 3 — Unobservable inputs that are supported by little or no market activity and that are based on management’s assumptions, including fair value measurements determined by using pricing models, discounted cash flow methodologies or similar techniques. The Company determined the fair value of its Level 1 financial instruments, which are traded in active markets, using quoted market prices for identical instruments. Marketable investments classified within Level 2 of the fair value hierarchy are valued based on other observable inputs, including broker or dealer quotations, alternative pricing sources or U.S. Government Treasury yield of appropriate term. When quoted prices in active markets for identical assets or liabilities are not available, the Company relies on non-binding quotes from its investment managers, which are based on proprietary valuation models of independent pricing services. These models generally use inputs such as observable market data, quoted market prices for similar instruments, historical pricing trends of a security as relative to its peers. To validate the fair value determination provided by its investment managers, the Company reviews the pricing movement in the context of overall market trends and trading information from its investment managers. The Company performs routine procedures such as comparing prices obtained from independent source to ensure that appropriate fair values are recorded. Because the transfer of Private Warrants to anyone outside of a small group of individuals constituting the sponsors of Gores Metropoulos, Inc. would result in the Private Warrants having substantially the same terms as the Public Warrants, management determined that the fair value of each Private Warrant is the same as that of a Public Warrant, with an insignificant adjustment for short-term marketability restrictions, as of December 31, 2020. As of March 31, 2021, management determined the fair value of the Private Warrants using observable inputs in the Black-Scholes valuation model, which used the remaining term of warrants of 4.68 years, volatility of 64.2% and a risk-free rate of 0.83%. Accordingly, the Private Warrants are classified as Level 3 financial instruments. The following table presents changes in Level 3 liabilities relating to Private Warrants measured at fair value as of March 31, 2021 (in thousands): Private Warrants Balance as of December 31, 2020 $ — Additions 51,753 Exercise — Measurement adjustments — Balance as of March 31, 2021 $ 51,753 The Company’s financial assets and liabilities subject to fair value measurements on a recurring basis and the level of inputs used for such measurements were as follows (in thousands): Fair Value (in thousands) Measured as of Level 1 Level 2 Level 3 Total Assets: Cash equivalents: Money market funds $ 19,035 $ — $ — $ 19,035 U.S. Treasury — — — — Commercial paper — 166,255 — 166,255 Total cash equivalents $ 19,035 $ 166,255 $ — $ 185,290 Marketable investments: U.S. Treasury $ 210,709 $ — $ — $ 210,709 U.S. agency and government sponsored securities — — — — Commercial paper — 106,209 — 106,209 Corporate bonds — 61,672 — 61,672 Asset-backed securities — 8,051 — 8,051 Equity investments $ 16,950 $ — $ — $ 16,950 Total marketable investments $ 227,659 $ 175,932 $ — $ 403,591 Liabilities: Public Warrants $ — $ — $ — $ — Private Warrants — — 51,753 51,753 Total warrant liabilities $ — $ — $ 51,753 $ 51,753 Fair Value (in thousands) Measured as of Level 1 Level 2 Level 3 Total Assets: Cash equivalents: Money market funds $ 64,971 $ — $ — $ 64,971 U.S. Treasury 24,999 — — 24,999 Commercial paper — 108,322 — 108,322 Total cash equivalents $ 89,970 $ 108,322 $ — $ 198,292 Marketable investments: U.S. Treasury $ 130,348 $ — $ — $ 130,348 U.S. agency and government sponsored securities — 19,996 — 19,996 Commercial paper — 73,898 — 73,898 Corporate bonds — 45,450 — 45,450 Asset-backed securities — 7,018 — 7,018 Total marketable investments $ 130,348 $ 146,362 $ — $ 276,710 Liabilities: Public Warrants $ 228,933 $ — $ — $ 228,933 Private Warrants — 114,467 — 114,467 Total warrant liabilities $ 228,933 $ 114,467 $ — $ 343,400

Earnings Per Share [Abstract]
Earnings (Loss) Per Share	Earnings (Loss) Per Share The Company computes earnings per share of Common Stock using the two-class method required for participating securities and does not apply the two-class method in periods of net loss. Earnings per share calculations for all periods prior to the Business Combination have been retrospectively restated to the equivalent number of shares reflecting the exchange ratio established in the reverse capitalization. Subsequent to the Business Combination, earnings per share was calculated based on weighted average number of shares of common stock then outstanding. The following table sets forth the computation of basic and diluted loss per share for the three months ended March 31, 2021 and 2020: (in thousands, except for share and per share amounts): March 31, 2021 2020 Numerator: Net loss $ (75,923) $ (15,581) Deemed dividend attributable to BCF accretion — — Net loss attributable to common shareholders $ (75,923) $ (15,581) Denominator: Weighted average common shares outstanding- Basic 332,987,523 128,668,864 Dilutive effect of potential common shares — — Weighted average common shares outstanding- Diluted 332,987,523 128,668,864 Net loss per shares attributable to common shareholders- Basic and Diluted $ (0.23) $ (0.12) The following table presents the potential shares of Common Stock outstanding that were excluded from the computation of diluted net loss per share of common stock as of the periods presented because including them would have been antidilutive: March 31, 2021 2020 Warrants 7,166,301 5,060,907 Stock options 15,776,371 12,804,955 Restricted stock awards and restricted stock units 2,208,842 5,178,722 Series A Convertible Preferred Stock — 94,818,151 Founders Preferred Stock — 26,206,837 Earn-out shares 25,818,744 — Total 50,970,258 144,069,572

Share-based Payment Arrangement [Abstract]
Stock-based Compensation	Stock-based Compensation The Company maintained the 2015 Stock Plan (the “2015 Plan”) under which incentive stock options, non-qualified stock options, and restricted stock were granted to employees and non-employee consultants. In connection with the Business Combination, the Company assumed the 2015 Plan upon the Closing. The Company terminated the 2015 Plan, provided that the outstanding awards previously granted under the 2015 Plan continue to remain outstanding under the 2015 Plan. In December 2020, the Company’s Board adopted and the Company’s stockholders approved the 2020 Equity Incentive Plan (the “2020 Plan”). The 2020 Plan became effective upon the closing of the Business Combination. Under the 2020 Plan, as of March 31, 2021, the Company was authorized to issue a maximum number of 36,588,278 shares of Class A common stock. The Company granted 798,203 restricted stock units in the three months ended March 31, 2021. Stock Options Under the terms of the 2015 Plan, incentive stock options must have an exercise price at or above the fair market value of the stock on the date of the grant, while non-qualified stock options are permitted to be granted below fair market value of the stock on the date of grant. Stock options granted have service-based vesting conditions only. The service-based vesting conditions vary, though typically, stock options vest over four years with 25% of stock options vesting on the first anniversary of the grant and the remaining 75% vesting monthly over the remaining 36 months. Option holders have a 10-year period to exercise the options before they expire. Forfeitures are recognized in the period they occur. A summary of the Company’s stock option activity for the three months ended March 31, 2021 was as follows: Number of Weighted- Weighted- Aggregate Outstanding as of December 31, 2020 16,188,071 $ 1.67 Granted — — Exercised (183,918) 1.71 Forfeited (227,782) 1.71 Outstanding as of March 31, 2021 15,776,371 1.71 8.83 $ 356,546 The aggregate intrinsic value of stock options exercised during the three months ended March 31, 2021 and 2020 was $4.5 million and $0, respectively. The intrinsic value is calculated as the difference between the exercise price and the fair value of the common stock on the exercise date. The total grant-date fair value of the options vested was $1.9 million and $0.2 million, respectively, during the three months ended March 31, 2021 and 2020, respectively. Restricted Stock Awards Prior to June 30, 2019, the Company granted restricted stock awards to employees. Recipients purchased the restricted stock on the grant date and the Company has the right to repurchase the restricted shares at the same price recipients paid to obtain those shares. The restrictions lapse solely based on continued service, and generally lapse over 4 years —25% on the first anniversary of the date of issuance, and the remaining 75% monthly over the remaining 36 months. At the grant date of the award, recipients of restricted stock are granted voting rights and receive dividends on unvested shares. No restricted stock awards have been granted after June 30, 2019. Restricted stock awards activity for the three months ended March 31, 2021 was as follows: Shares Weighted Average Outstanding as of December 31, 2020 1,815,891 $ 1.15 Granted — — Forfeited (47,444) 1.10 Vested (357,808) 0.83 Outstanding as of March 31, 2021 1,410,639 1.13 Restricted Stock units A summary of the Company’s restricted stock units activity for the three months ended March 31, 2021 was as follows: Shares Weighted Average Outstanding as of December 31, 2020 — $ — Granted 798,203 28.18 Forfeited — — Vested — — Outstanding as of March 31, 2021 798,203 28.18 Compensation expense Stock-based compensation expense by function was as follows (in thousands): Three Months Ended March 31, 2021 2020 Cost of sales $ 83 $ 72 Research and development 762 435 Sales and marketing 186 82 General and administrative 806 540 Total $ 1,837 $ 1,129

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The effective tax rate was 0% and 0% for the three months ended March 31, 2021 and 2020, respectively. The three months effective tax rates differ significantly from our statutory tax rate of 21%, primarily due to the Company’s valuation allowance movement in each period. The realization of tax benefits of deferred tax assets is dependent upon future levels of taxable income, of an appropriate character, in the periods the items are expected to be deductible or taxable. Based on the available objective evidence, the Company does not believe it is more likely than not that the net deferred tax assets will be realizable. Accordingly, the Company has provided a full valuation allowance against the domestic net deferred tax assets as of March 31, 2021 and December 31, 2020. The Company intends to maintain the remaining valuation allowance until sufficient positive evidence exists to support a reversal of, or decrease in, the valuation allowance. The Company reports income tax related interest and penalties within its provision for income tax in its condensed consolidated statements of operations. Similarly, the Company reports the reversal of income tax-related interest and penalties within its provision for income tax line item to the extent the Company resolves its liabilities for uncertain tax positions in a manner favorable to its accruals therefor. During the three months ended March 31, 2021, there were no material changes to the total amount of unrecognized tax benefits.

Leases [Abstract]
Leases	Leases The Company leases manufacturing equipment under non-cancelable finance leases expiring at various dates through December 2025. The Company also leases office and manufacturing facilities under non-cancelable operating leases expiring at various dates through June 2026. Some of the Company’s leases include one or more options to renew, with renewal terms that if exercised by the Company, extend the lease term from one The Company adopted ASC 842 using the modified retrospective method on January 1, 2021. The Company elected the available package of practical expedients and implemented internal controls to enable the preparation of financial information upon adoption. The most significant impact of the adoption of ASC 842 was the recognition of right-of-use, or ROU, assets and lease liabilities for operating leases of $10.8 million and $12.0 million, respectively, and a reversal of deferred rent of $1.2 million on January 1, 2021. The Company’s accounting for finance leases remained substantially unchanged. The adoption of ASC 842 did not have any impact on the Company’s operating results or cash flows. The Company determines if an arrangement is or contains a lease at inception. Operating leases are included in operating lease right-of use assets and operating lease liabilities in the Company’s condensed consolidated balance sheets. Finance leases are included in property and equipment, and finance lease liabilities in the Company’s condensed consolidated balance sheets. Right-of-use 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. Operating lease right-of-use assets and liabilities are recognized at the commencement date based on an amount equal to the present value of lease payments over the lease term. The Company’s leases do not provide an implicit rate, therefore the Company uses an incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. The Company uses the implicit rate when it is readily determinable. The Company elected the package of practical expedients permitted under the transition guidance within the new standard, which among other things, allowed it to carry forward existing lease classification and to exclude leases with original terms of one year or less. Further, the Company elected to combine lease and non-lease components for all asset classes. Any variable lease components are expensed as incurred. The operating lease right-of-use asset also include adjustments related to prepaid or deferred lease payments and lease incentives. The Company’s lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Operating lease expense for lease payments is recognized on a straight-line basis over the lease term.

The Company had purchase obligations primarily for purchases of inventory, R&D, and general and administrative activities totaling $10.7 million as of March 31, 2021, which are expected to be received within a year. Legal Matters From time to time, the Company is involved in actions, claims, suits and other proceedings in the ordinary course of business, including assertions by third parties relating to intellectual property infringement, breaches of contract or warranties or employment-related matters. When it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated, the Company records a liability for such loss contingencies. The Company’s estimates regarding potential losses and materiality are based on the Company’s judgment and assessment of the claims utilizing currently available information. Although the Company will continue to reassess its reserves and estimates based on future developments, the Company’s objective assessment of the legal merits of such claims may not always be predictive of the outcome and actual results may vary from the Company’s current estimates.

Basis of Presentation and Summary of Significant Accounting Policies (Policies)	3 Months Ended
	Mar. 31, 2021
Accounting Policies [Abstract]
Basis of Presentation and Consolidation	Basis of Presentation and Consolidation The accompanying condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, these condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020. In the opinion of management, the condensed consolidated financial statements reflect all adjustments, which are normal and recurring in nature, necessary for fair financial statement presentation. All intercompany transactions and balances have been eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make judgments, estimates and assumptions that affect the reported amounts of assets, liabilities, equity, revenues and expenses, and related disclosures. The significant estimates made by management include inventory reserves, valuation allowance for deferred tax assets, valuation of warrants, revenue, stock-based compensation expense and other loss contingencies. Management periodically evaluates such estimates and they are adjusted prospectively based upon such periodic evaluation. Actual results could differ from those estimates.
Segment Information	Segment InformationThe Company has determined its operating segments on the same basis that it uses to evaluate its performance internally. The Company has two business activities: (i) manufacturing and distribution of lidar sensors that measure distance using laser light to generate a highly accurate 3D map for automotive mobility applications and (ii) development of ultra-sensitive pixel-based sensors and designing, testing and providing consulting services for non-standard integrated circuits that are essential for systems to meet the requirement of customers. The Company’s operating segments are (i) Autonomy Solutions and (ii) Component Sales. The Company’s chief operating decision maker (“CODM”), its Chief Executive Officer, reviews the operating results of these segments for the purpose of allocating resources and evaluating financial performance.
Concentration of Credit Risk	Concentration of Credit Risk Financial instruments that potentially subject the Company to significant concentrations of credit risk, consist primarily of cash and cash equivalents, marketable investments and accounts receivable. A significant portion of the Company’s cash and cash equivalents is held at high-quality domestic financial institutions. Deposits held with the financial institutions may, at times, exceed the amount of insurance provided on such deposits . The Company held cash in foreign entities of $0.5 million and $0.6 million as of March 31, 2021 and December 31, 2020, respectively. The Company’s revenue is derived from customers located in the United States and international markets. The Company mitigates its credit risks by performing ongoing credit evaluations of its customers’ financial conditions and requires advance payment from customers in certain circumstances. The Company generally does not require collateral.
Equity Investments	Equity Investments The Company’s holds marketable equity investments, over which the Company does not have a controlling interest or significant influence. Marketable equity investments are measured using the quoted prices in active markets with changes recorded in other income (expense), net on the condensed consolidated statement of operations.
Recently Adopted Accounting Pronouncements and Recent Accounting Pronouncements Not Yet Effective	Recently Adopted Accounting Pronouncements In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) No. 2016-02, Leases (Topic 842) and issued subsequent amendments to the initial guidance in 2017, 2018 and 2019 (collectively “ASC 842”). Under the new guidance, a lessee is required to recognize assets and liabilities for both finance, previously known as capital, and operating leases with lease terms of more than 12 months. The ASU also requires disclosures to help investors and other financial statement users better understand the amount, timing, and uncertainty of cash flows arising from leases. In transition, the Company recognized and measured leases at the beginning of the period of adoption, January 1, 2021, using a modified retrospective approach that included a number of optional practical expedients that the Company elected to apply. See Note 11 for disclosure on the impact of adopting this standard. Recent Accounting Pronouncements Not Yet Effective In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (ASC 326) : Measurement of Credit Losses of Financial Instruments, which, together with subsequent amendments, amends the requirement on the measurement and recognition of expected credit losses for financial assets held. ASU 2016-13 will be effective for the Company beginning January 1, 2023, with early adoption permitted. The Company is currently in the process of evaluating the effects of this pronouncement on the Company’s financial statements and does not expect it to have a material impact on the consolidated financial statements.
Fair Value Measurements	Fair Value Measurements The Company carries cash equivalents, marketable investments, and Public and Private Warrants. Fair value is based on the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is estimated by applying the following hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement: Level 1 — Observable inputs, which include unadjusted quoted prices in active markets for identical assets or liabilities. Level 2 — Observable inputs other than Level 1 inputs, such as quoted prices 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. Level 3 — Unobservable inputs that are supported by little or no market activity and that are based on management’s assumptions, including fair value measurements determined by using pricing models, discounted cash flow methodologies or similar techniques. The Company determined the fair value of its Level 1 financial instruments, which are traded in active markets, using quoted market prices for identical instruments. Marketable investments classified within Level 2 of the fair value hierarchy are valued based on other observable inputs, including broker or dealer quotations, alternative pricing sources or U.S. Government Treasury yield of appropriate term. When quoted prices in active markets for identical assets or liabilities are not available, the Company relies on non-binding quotes from its investment managers, which are based on proprietary valuation models of independent pricing services. These models generally use inputs such as observable market data, quoted market prices for similar instruments, historical pricing trends of a security as relative to its peers. To validate the fair value determination provided by its investment managers, the Company reviews the pricing movement in the context of overall market trends and trading information from its investment managers. The Company performs routine procedures such as comparing prices obtained from independent source to ensure that appropriate fair values are recorded. Because the transfer of Private Warrants to anyone outside of a small group of individuals constituting the sponsors of Gores Metropoulos, Inc. would result in the Private Warrants having substantially the same terms as the Public Warrants, management determined that the fair value of each Private Warrant is the same as that of a Public Warrant, with an insignificant adjustment for short-term marketability restrictions, as of December 31, 2020. As of March 31, 2021, management determined the fair value of the Private Warrants using observable inputs in the Black-Scholes valuation model, which used the remaining term of warrants of 4.68 years, volatility of 64.2% and a risk-free rate of 0.83%. Accordingly, the Private Warrants are classified as Level 3 financial instruments. The following table presents changes in Level 3 liabilities relating to Private Warrants measured at fair value as of March 31, 2021 (in thousands): Private Warrants Balance as of December 31, 2020 $ — Additions 51,753 Exercise — Measurement adjustments — Balance as of March 31, 2021 $ 51,753
Leases	The Company determines if an arrangement is or contains a lease at inception. Operating leases are included in operating lease right-of use assets and operating lease liabilities in the Company’s condensed consolidated balance sheets. Finance leases are included in property and equipment, and finance lease liabilities in the Company’s condensed consolidated balance sheets.Right-of-use 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. Operating lease right-of-use assets and liabilities are recognized at the commencement date based on an amount equal to the present value of lease payments over the lease term. The Company’s leases do not provide an implicit rate, therefore the Company uses an incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. The Company uses the implicit rate when it is readily determinable. The Company elected the package of practical expedients permitted under the transition guidance within the new standard, which among other things, allowed it to carry forward existing lease classification and to exclude leases with original terms of one year or less. Further, the Company elected to combine lease and non-lease components for all asset classes. Any variable lease components are expensed as incurred. The operating lease right-of-use asset also include adjustments related to prepaid or deferred lease payments and lease incentives. The Company’s lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Operating lease expense for lease payments is recognized on a straight-line basis over the lease term.
