The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Items subject to such estimates and assumptions include, but are not limited to, the useful lives of long-lived assets, revenue recognition, sales return reserve, allowances for inventory valuation, the realizability of deferred tax assets, the measurement of stock-based compensation, and the valuation of the Company’s various financial instruments (including preferred stock and warrants). The Company bases its estimates on historical experience and on various other assumptions that the Company believes to be reasonable under the circumstances. On an ongoing basis, the Company evaluates these assumptions, judgments and estimates. Actual results may differ from these estimates.

The Company is not aware of any specific event or circumstances that would require an update to estimates, judgments or assumptions or a revision to the carrying value of the Company’s assets or liabilities as of the date these financial statements were available to be issued. These estimates, judgments and assumptions may change in the future, as new events occur, or additional information is obtained.

The Company has been actively monitoring the COVID-19 situation and its impact on the Company’s business. In response to the pandemic, numerous state and local jurisdictions have imposed “shelter-in-place” orders, quarantines and other restrictions. In the United States, governmental authorities have recommended, and in certain cases required, that elective, specialty and other procedures and appointments, be suspended or canceled. Similarly, in March and December 2020, the governor of California, where the Company’s headquarters are located, issued “stay at home” orders limiting non-essential activities, travel and business operations. Such orders or restrictions have resulted in reduced operations at the Company’s headquarters (including its manufacturing facility), work stoppages, slowdowns and delays, travel restrictions and cancellation of events and have restricted the efforts of the Company’s sales representatives, thereby significantly and negatively impacting the Company’s operations.

The full extent to which the COVID-19 pandemic will directly or indirectly impact our business, results of operations and financial condition, including sales, expenses, reserves and allowances, manufacturing, research and development costs and employee-related amounts, will depend on future developments that are highly uncertain, including as a result of new information that may emerge concerning COVID-19 and the actions taken to contain it or treat COVID-19, as well as the economic impact on local, regional, national and international customers and markets. The situation surrounding COVID-19 remains fluid and the potential for a material impact on the Company increases the longer the virus impacts the level of economic activity in the United States and globally.

The functional currency of the Company and its subsidiaries is the U.S. dollar. Accordingly, non-U.S. dollar denominated monetary assets and liabilities are re-measured into U.S. dollars at the exchange rates in effect at the reporting date, non-monetary assets and liabilities are recorded at historical rates, and revenue and expenses are recorded at average exchange rates in effect during each reporting period. Foreign currency transaction gains and losses are recorded in other income (expense), net in the unaudited condensed consolidated statements of operations and comprehensive loss.

The Company follows the two-class method when computing net loss per common share. The two-class method determines net loss per common share for each class of common and participating securities according to dividends declared or accumulated and participation rights in undistributed earnings. The two-class method requires income available to common stockholders for the period to be allocated between common and participating securities based upon their respective rights to receive dividends as if all income for the period had been distributed.

computed by adjusting net loss attributable to common stockholders to reallocate undistributed earnings based on the potential impact of dilutive securities. Diluted net loss per common share attributable to common stockholders is computed by dividing the diluted net loss attributable to common stockholders by the weighted average number of common shares outstanding for the period, including potential dilutive common shares assuming the dilutive effect of common stock equivalents.

The Company’s redeemable convertible preferred stock contractually entitled the holders of such shares to participate in dividends but does not contractually require the holders of such shares to participate in losses of the Company. Accordingly, in periods in which the Company reports a net loss, such losses are not allocated to such participating securities. In periods in which the Company reports a net loss attributable to common stockholders, diluted net loss per common share attributable to common stockholders is the same as basic net loss per common share attributable to common stockholders, since dilutive common shares are not assumed to have been issued if their effect is anti-dilutive. The Company reported a net loss attributable to common stockholders for the three months ended March 31, 2021 and 2020.

Comprehensive loss is comprised of net loss and other comprehensive income (loss). The Company has no components of other comprehensive loss. Therefore, net loss equals comprehensive loss for all periods presented and, accordingly, the Consolidated Statements of Comprehensive Loss is not presented in a separate statement.

The Company operates as one reportable and operating segment, which relates to the sale of lidar sensor kits. The Company’s chief operating decision maker is its chief executive officer, who reviews financial information presented on a consolidated basis for purposes of making operating decisions, assessing financial performance and allocating resources.

In accordance with ASC 606, revenue is recognized when a customer obtains control of promised products or services. The amount of revenue recognized reflects the consideration that the Company expects to be entitled to receive in exchange for these products or services. To achieve the core principle of this standard, the Company performs the following five steps:

The Company considers the terms and conditions of revenue contracts and its customary business practices in identifying contracts under ASC 606. It is determined that a contract with a customer exists when the contract is approved, each party’s rights regarding the product or services to be transferred and the payment terms for the product or services can be identified, it is determined that the customer has the ability and intent to pay and the contract has commercial substance. The Company applies judgement in determining the customer’s ability and intent to pay, which is based on a variety of factors, including the customer’s historical payment experience or, in the case of a new customer, credit and financial information pertaining to the customer.

Performance obligations promised in a contract are identified based on the product or services that will be transferred to the customer that are both capable of being distinct, whereby the customer can benefit from the product or service either on its own or together with other resources that are readily available from third parties or from the Company, and are distinct in the context of the contract, whereby the transfer of the product or services is separately identifiable from other promises in the contract. The Company’s performance obligations consist of (i) sale of lidar sensor kits and (ii) product development and validation services.

The transaction price is determined based on the consideration to which the Company expects to be entitled in exchange for transferring product or services to the customer. Variable consideration is included in the transaction price if the Company judges that it is probable that a significant future reversal of cumulative revenue under the contract will not occur. The Company does not have a material amount of variable consideration in its agreements with customers. None of the Company’s contracts contain a significant financing component. All taxes assessed by a governmental authority on a specific revenue-producing transaction collected by the Company from a customer are excluded from the transaction price.

If the contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. Contracts that contain multiple performance obligations require an allocation of the transaction price to each performance obligation based on a relative standalone selling price (“SSP”). In each of the three months ended March 31, 2021 and 2020, the Company did not have a material volume of contracts that required the allocation of transaction price to multiple performance obligations.

Revenue is recognized at the time the related performance obligation is satisfied by transferring the promised product or service to a customer. Revenue is recognized when control of products or services is transferred to customers, in an amount that reflects the consideration that the Company expects to receive in exchange for those products or services. The Company generates all of its revenue from contracts with customers and applies judgment in identifying and evaluating any terms and conditions in contracts which may impact revenue recognition.

The majority of the Company’s revenue comes from product sales of lidar sensor kits to customers. Revenue is recognized at a point in time when control of the goods is transferred to the customer, generally occurring upon shipment. Product sales to certain customers may require customer acceptance due to performance acceptance criteria that is considered more than a formality. For these product sales, revenue is recognized upon the expiration of the customer acceptance period. Amounts billed to customers related to shipping and handling are classified as revenue, and the Company has elected to recognize the cost of shipping activities that occur after control has transferred to the customer as a fulfillment cost rather than a separate performance obligation. All related shipping costs are accrued and recognized within cost of revenue when the related revenue is recognized. Taxes collected from customers and remitted to governmental authorities are excluded from revenue on the net basis of accounting. Accounts receivable are due under normal trade terms, typically three months or less. Revenue from sale of lidar sensor kits, which are recognized at a point in time, was approximately $6.6 million and $2.3 million in the three months ended March 31, 2021 and 2020, respectively.

When a contract involves multiple performance obligations, the Company accounts for individual performance obligation separately if the customer can benefit from the performance obligation on its own or with other resources that are readily available to the customer and the performance obligation is separately identifiable from other promises in the arrangement. The consideration is allocated between separate performance obligations in proportion to their estimated standalone selling price. The standalone selling price reflects the price the Company would charge for a specific performance obligation if it were sold separately in similar circumstances and to similar customers.

The Company provides standard product warranties for a term of typically two years to ensure that its lidar sensors comply with agreed-upon specifications. Standard warranties are considered to be assurance type warranties and are not accounted for as separate performance obligations.

The Company expenses the incremental costs of obtaining a contract when incurred because the amortization period for these costs would be less than one year. These costs primarily relate to sales commissions and are expensed as incurred in sales and marketing expense in the Company’s consolidated statements of operations and comprehensive loss. The expense was $0.3 million for the three months ended March 31, 2021. No commission plan was in place and no expense was recognized for the three months ended March 31, 2020.

The Company’s general terms and conditions for its contracts do not contain a right of return that allows the customer to return products and receive a credit, however it has in practice permitted returns of its sensor kits in limited circumstances up to six months after purchase. Allowances for sales returns, which reduce revenue, are estimated using historical experience and were immaterial as of March 31, 2021 and December 31, 2020. Actual returns in subsequent periods have been consistent with estimated amounts.

Revenue allocated to remaining performance obligations represents the transaction price allocated to the performance obligations that are unsatisfied, or partially unsatisfied. It includes unearned revenue and amounts that will be invoiced and recognized as revenue in future periods and does not include contracts where the customer is not committed. The customer is not considered committed where they are able to terminate for convenience without payment of a substantive penalty under the contract. Additionally, as a practical expedient, the Company has not disclosed the value of unsatisfied performance obligations for contracts with an original expected length of one year or less.

In certain arrangements, the Company receives payment from a customer either before or after the performance obligation has been satisfied. The expected timing difference between the payment and satisfaction of performance obligations for the vast majority of the Company’s contracts is one year or less; therefore, the Company applies a practical expedient and does not consider the effects of the time value of money. The Company’s contracts with customer prepayment terms do not include a significant financing component because the primary purpose is not to receive financing from the customers.

The Company may modify contracts to offer customers additional products or services. Each of the additional products and services are generally considered distinct from those products or services transferred to the customer before the modification. The Company evaluates whether the contract price for the additional products and services reflects the standalone selling price as adjusted for facts and circumstances applicable to that contract. In these cases, the Company accounts for the additional products or services as a separate contract. In other cases where the pricing in the modification does not reflect the standalone selling price as adjusted for facts and circumstances applicable to that contract, the Company accounts for the additional products or services as part of the existing contract primarily on a prospective basis.

Accounting for contracts recognized over time under ASC 606 involves the use of various techniques to estimate total contract revenue and costs. Due to uncertainties inherent in the estimation process, it is possible that estimates of costs to complete a performance obligation will be revised in the near-term. The Company reviews and updates its contract-related estimates regularly, and records adjustments as needed. For those performance obligations for which revenue is recognized using a cost-to- cost input method, changes in total estimated costs, and related progress towards complete satisfaction of the performance obligation, are recognized on a cumulative catch-up basis in the period in which the revisions to the estimates are made.

Restricted cash consists of certificates of deposit held by a bank as security for outstanding letters of credit. The Company had a restricted cash balance of $1.3 million and $1.3 million as of March 31, 2021 and December 31, 2020, respectively, which has been excluded from the Company’s cash and cash equivalents balances. The Company presented $0.3 million of the total amount of restricted cash within current assets on the condensed consolidated balance sheets as of March 31, 2021 and

Financial instruments that potentially subject the Company to credit risk consist primarily of cash, cash equivalents, and restricted cash, and accounts receivable. Cash, cash equivalents and restricted cash are deposited with federally insured commercial banks in the United States and at times cash balances may be in excess of federal insurance limits. The Company generally does not require collateral or other security deposits for accounts receivable.

To reduce credit risk, the Company considers customer creditworthiness, past transaction history with the customer, current economic industry trends, and changes in customer payment terms when determining the collectability of specific customer accounts. Past due balances over 90 days and other higher risk amounts are reviewed individually for collectability. Based on management’s assessment, the Company provides for estimated uncollectible amounts through a charge to earnings and a credit to valuation allowance. Balances that remain outstanding after the Company has used reasonable collection efforts are written off through a charge to the valuation allowance and a credit to accounts receivable.

One supplier accounted for approximately 17% of total purchases during the three months ended March 31, 2021 and accounted for 48% of total accounts payable as of March 31, 2021. One supplier accounted for approximately 11% of total purchases during the three months ended March 31, 2020 and accounted for 23% of total accounts payable balance as of December 31, 2020.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326), to introduce a new impairment model for recognizing credit losses on financial instruments based on an estimate of current expected credit losses (“ECL”). Under the new model, an entity is required to estimate ECL on available-for-sale (AFS) debt securities only when the fair value is below the amortized cost of the asset and is no longer based on an impairment being “other-than-temporary”. The new model also requires the impairment calculation on an individual security level and requires an entity to use the present value of cash flows when estimating the ECL. The credit-related losses are required to be recognized through earnings and non-credit related losses are reported in other comprehensive income. The ASU will be effective for fiscal years beginning after December 15, 2022 and early adoption is permitted. The new guidance will require modified retrospective application to all outstanding instruments, with a cumulative effect adjustment recorded to opening retained earnings as of the beginning of the first period in which the guidance becomes effective. The Company does not believe the adoption of this new guidance will have a material impact on its unaudited condensed consolidated financial statements.

In August 2018, the FASB issued ASU 2018-15, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract, which aligns the requirements for capitalizing implementation costs incurred in a cloud computing arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. This ASU is effective for the Company for fiscal years beginning after December 15, 2020 and interim periods within annual periods beginning after December 15, 2021. Early adoption is permitted. The Company is currently evaluating the effect of the guidance on its unaudited condensed consolidated financial statements and disclosures.

In December 2019, the FASB issued ASU No. 2019-12, Income Taxes. ASU 2019-12 simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740 and by improving consistent application of other areas of Topic 740. The new standard is effective for the Company for annual periods beginning after December 15, 2021 and interim periods within fiscal years beginning after December 15, 2022, with early adoption permitted. The Company is currently evaluating the effect of the guidance on its condensed consolidated financial statements and disclosures.
