Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies 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 filed with the Securities and Exchange Commission and have not materially changed during the three months ended June 30, 2021. Revenue Recognition The Company derives revenue from primarily two sources, product and service revenues, which are discussed further below. The Company recognizes revenue using a five step process. This process involves identifying the contract with a customer, determining the performance obligations in the contract, determining the contract price, allocating the contract price to the distinct performance obligations in the contract based on stand-alone selling price, and recognizing revenue when the performance obligations have been satisfied. A performance obligation is considered distinct from other obligations in a contract when it provides a benefit to the customer either on its own or together with other resources that are readily available to the customer and is separately identified in the contract. The Company considers a performance obligation satisfied once it has transferred control of a good or service to the customer, meaning the customer has the ability to use and obtain the benefit of the good or service. The Company’s agreements with customers often include multiple performance obligations, which can sometimes be included in separate contracts entered into within a reasonably short period of time. The Company considers an entire customer arrangement to determine if separate contracts should be considered combined for the purposes of revenue recognition. In order to determine the stand-alone selling price, the Company conducts a periodic analysis to determine whether various goods or services have an observable stand-alone selling price as well as to identify significant changes to current stand-alone selling prices. If the Company does not have an observable stand-alone selling price for a particular good or service, then the stand-alone selling price for that particular good or service is estimated using an approach that maximizes the use of observable inputs. The Company’s process for determining stand-alone selling price requires judgment and considers multiple factors that are reasonably available and maximizes the use of observable inputs that may vary over time depending upon the unique facts and circumstances related to each performance obligation. The Company believes that this method results in an estimate that represents the price the Company would charge for the product offerings if they were sold separately. For most of its performance obligations, the Company has established stand-alone selling price as a range rather than a single value, such range being plus or minus 15% of the weighted average of observable prices. If the contractually stated prices of all the performance obligations in a contract fall within their respective stand-alone selling price ranges, the Company will allocate the transaction price at the contractually stated amounts. In situations where the contractually stated price for one or more performance obligations in a contract fall(s) outside of their respective stand-alone selling price range, the Company will use the mid-point of the respective stand-alone selling price range for performance obligations in the contract priced outside of their respective stand-alone selling price range(s) and the contract values for performance obligations priced within their respective stand-alone selling price range(s), to allocate the transaction price on a relative stand-alone selling price basis. Taxes, such as sales, value-add and other taxes, collected from customers concurrent with revenue generating activities and remitted to governmental authorities are not included in revenue. Shipping and handling costs associated with outbound freight are accounted for as a fulfillment cost and are included in cost of sales. The following describes the nature of the Company’s primary types of revenue and the revenue recognition policies and significant payment terms as they pertain to the types of transactions the Company enters into with its customers. Product revenues Product revenues are comprised of two major revenue streams, direct platform sales and consumables. Direct platform sales revenues are comprised of advanced automation systems (including fully-paid workflow licenses) as well as Culture Station instruments. Direct platform sales also include revenue from subscription arrangements in which customers are able to subscribe to a specific workflow and pay a quarterly fee over a fixed period of time which covers the annual workflow license, the advanced automation system, as well as warranty and service. Consumables revenues are comprised of OptoSelect chips required to run the system as well as reagent kits. The Company’s standard arrangement with its customers is generally a purchase order or an executed contract. Revenue on product sales is recognized when control has transferred to the customer which typically occurs when the product has been shipped to the customer, risk of loss has transferred to the customer and the Company has a present right to payment for the system, chip or kit, as applicable. In certain limited circumstances when a product sale includes client acceptance provisions, the Company will first assess such terms to determine if the control of the good is being transferred to the customer in accordance with the agreed-upon specifications in the contract. To the extent that such acceptance provisions can be objectively determined to be aligned with the standard specifications of the arrangement, are defined and easily evaluated for completion, as well as do not afford the customer any additional rights or create additional performance obligations for the Company, such provisions would be determined perfunctory and would not preclude revenue recognition presuming all other criteria are met. If such acceptance provisions are considered to be substantive, revenue is recognized either when client acceptance has been obtained, client acceptance provisions have lapsed, or the Company has objective evidence that the criteria specified in the client acceptance provisions have been satisfied. Payment terms are generally thirty to ninety days from the date of invoicing. On a limited basis, the Company also enters into fixed-term sales-type lease arrangements with certain qualified customers. Revenue from sales-type lease arrangements is generally recognized in a manner consistent with platform systems, assuming all other revenue recognition criteria have been met. Service revenues Service revenues primarily consist of joint development agreements, service and warranty, training and installation services, platform support and feasibility studies on the Company’s advanced automation systems and workflows. The Company’s services are provided primarily on a fixed fee basis; from time to time these fixed fee contracts may be invoiced at the outset of the arrangements. The Company recognizes revenue from the sale of extended warranty and enhanced service warranty arrangements over the respective period, while revenue on feasibility studies is recognized over time, using an input measure of progress based on costs incurred to date relative to total expected costs. Revenue on platform support is recognized as the services are performed. Service contracts are typically short-term in nature. Payment terms are generally thirty to ninety days from the date of invoicing. Joint development agreements are agreements whereby the Company provides services for the development of customized advanced automation systems or workflows, or for customized workflows and consumables to meet a specific customer’s needs. Such contracts can be executed on a time-and-materials basis as well as include defined milestones associated with these development activities over extended periods of time, some in excess of twenty-four months. Typically, there are formal customer acceptance clauses as each milestone is completed, and an approval to proceed with the next milestone is generally required. The Company recognizes revenue over time, using an input measure of progress based on costs incurred to date relative to total expected costs. Payment terms are generally thirty to ninety days from the achievement of each milestone. The Company only includes variable consideration in the transaction price to the extent that it is not probable that a significant reversal of revenue will occur for that amount. The constraint estimate is reassessed at each reporting date until the uncertainty is resolved. Contract assets and contract liabilities Contract assets include amounts where revenue recognized exceeds the amount invoiced to the customer and the right to payment is not solely subject to the passage of time. The Company’s contract asset balances of $3.8 million and $2.7 million as of June 30, 2021 and December 31, 2020, respectively, are primarily from its sales-type lease arrangements as well as its development and feasibility study agreements. The Company does not have impairment losses associated with contracts with customers for the three and six months ended June 30, 2021 and 2020. Contract liabilities consist of fees invoiced or paid by the Company’s customers for which the associated services have not been performed and revenues have not been recognized based on the Company’s revenue recognition criteria described above. Such amounts are reported as deferred revenue on the condensed consolidated balance sheets. Deferred revenue that is expected to be recognized during the following twelve months is recorded as a current liability and the remaining portion is recorded as non-current. Contract assets and contract liabilities are reported in a net position on an individual contract basis at the end of each reporting period. Contract assets are classified as current or long-term on the condensed consolidated balance sheet based on the timing of when the Company expects to complete the related performance obligations and invoice the customers. Contract liabilities are classified as current or long-term on the condensed consolidated balance sheet based on the timing when the revenue recognition associated with the related customer payments and invoicing is expected to occur. Costs to obtain or fulfill a contract Origination costs relate primarily to the payment of incentive bonuses to individuals that are directly related to sales transactions. Fulfillment costs generally include the direct cost of services such as platform support and feasibility studies. Origination and fulfillment costs that are internal to the Company are generally expensed when incurred because most of those costs are incurred concurrently with the delivery of the related goods and services, which are predominantly recognized at a point in time or are less than one year in nature. The origination costs that are related to long-term development agreements are capitalized and amortized over the relevant service period. The origination costs that are related to long-term development agreements are not material as of June 30, 2021 and 2020. Stock-Based Compensation The Company maintains an incentive compensation plan under which incentive stock options, nonqualified stock options and restricted stock units (“RSUs”) are granted primarily to employees and non-employee consultants. Stock-based compensation expense for stock-based awards is based on the grant date fair value. The Company determines the fair value of RSUs based on the closing value of its stock price listed on Nasdaq at the date of the grant. The Company estimates the fair value of stock option awards on the grant date using the Black-Scholes option-pricing model. The fair value of stock option 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. Stock option awards that include a service condition and a performance condition are considered expected to vest when the performance condition is probable of being met. Compensation expense associated with performance awards that are determined to be probable of achievement is recognized over the requisite service period, provided the grantee remains an employee or consultant of the Company through each applicable vesting date. For performance awards not initially assessed as probable of achievement, the Company records a cumulative adjustment to compensation expense in the period the Company changes its determination that a performance condition becomes probable of being achieved. The Company ceases recognition of compensation expense in any periods where the Company determines the attainment of a performance condition is no longer probable. If the performance goals are determined to be improbable, no compensation expense is recognized and any previously recognized compensation expense is reversed. Product Warranties The Company provides a 13-month assurance-type warranty on its platforms and chip consumables. Upon shipment, the Company establishes an accrual for estimated warranty expenses based on historical data and trends of product reliability and costs of repairing and replacing defective products. The Company exercises judgment in estimating the expected product warranty costs, using data such as the actual and projected product failure rates, estimated repair costs, freight, material, labor, and overhead costs. While management believes that historical experience provides a reliable basis for estimating such warranty cost, unforeseen quality issues or component failure rates could result in future costs in excess of such estimates, or alternatively, improved quality and reliability in the Company’s products could result in actual expenses that are below those currently estimated. Leases The Company determines the initial classification and measurement of its right-of-use assets and lease liabilities at the lease commencement date and thereafter, if modified. The lease term includes any renewal options and termination options that the Company is reasonably assured to exercise. The present value of lease payments is determined by using the interest rate implicit in the lease, if that rate is readily determinable; otherwise, the Company uses its incremental borrowing rate. The incremental borrowing rate is determined by using the rate of interest that the Company would pay to borrow on a collateralized basis an amount equal to the lease payments for a similar term and in a similar economic environment. Lease expense for operating leases is recognized on a straight-line basis over the lease term based on the total lease payments and is included in operating expenses in the condensed consolidated statements of operations and comprehensive loss. For all leases, rent payments that are based on a fixed index or rate at the lease commencement date are included in the measurement of lease assets and lease liabilities at the lease commencement date. The Company has elected the practical expedient to not separate lease and non-lease components. The Company’s non-lease components are primarily related to property maintenance and insurance. The Company also acts as a lessor to provide equipment financing through sales-type lease arrangements with certain qualified customers. Revenue from sales-type leases is presented on a gross basis when the company enters into a lease to realize value from a product that it would otherwise sell in its ordinary course of business. Amounts due and receivable under these arrangements are recorded at the outset of the arrangement as a contract asset in prepaid expenses and other current assets and other assets until such time that invoices are issued in accordance with the terms of the lease, at which point they are recorded as trade accounts receivable in the condensed consolidated balance sheets. Net Loss Attributable to Common Stockholders Per Share Net loss attributable to common stockholders per share is computed by dividing the weighted-average number of common shares outstanding for the period. Diluted net loss per share reflects the potential dilution that would occur if securities or other contracts to issue common stock were exercised or converted into common stock; however, potential common equivalent shares are excluded if their effect is anti-dilutive. In computing diluted net loss per share, the Company utilizes the treasury stock method. The Company applies the two-class method to compute basic and diluted net loss or income per share when it has issued shares that meet the definition of participating securities. The two-class method determines net (loss) or income per 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 net (loss) income available to common stockholders for the period to be allocated between common and participating securities based upon their respective rights to share in the earnings as if all net (loss) income for the period had been distributed. The Company’s convertible preferred stock participates in any dividends declared by the Company and are therefore considered to be participating securities. The participating securities are not required to participate in the losses of the Company, and therefore during periods of loss there is no allocation required under the two-class method.
