Revenue from Contract with Customer [Abstract]
Revenue	2. Revenue The Company recognizes revenue when control of promised goods or services is transferred to customers. The transfer of control generally occurs upon shipment when title and risk of loss pass to the customer. The vast majority of the Company’s revenue is generated from the sale of distinct products. Revenue is measured as the amount of consideration the Company expects to receive in exchange for such products, which is generally at contractually stated prices. Sales taxes and value added taxes collected concurrently with revenue generating activities are excluded from revenue. Performance Obligations Substantially all of the Company’s revenue is recognized at a point in time, upon shipment, rather than over time. At the request of its customers, the Company may perform professional services, generally for the maintenance and repair of products previously sold to those customers and for engineering services. Professional services for the maintenance and repair of products are typically short in duration, mostly less than one month, and generally involve a single distinct performance obligation. The related revenue is recognized at a point in time when control transfers to the customer upon completion of professional services. The consideration expected to be received in exchange for such services is typically the contractually stated amount. Certain engineering services are longer in duration and the related revenue is recognized over time. As the Company’s right to payment from a customer is based on the value of engineering services performed, the Company recognizes revenue based on the corresponding value to the customer from the Company’s performance completed to date. Revenue from engineering services aggregated to less than 3% of the Company’s consolidated revenue during the six months ended June 30, 2023 and July 1, 2022. The Company occasionally sells separately priced non-standard/extended warranty services or preventative maintenance plans with the sale of products. The transfer of control over the service plans is over time. The Company recognizes the related revenue ratably over the terms of the service plans. The transaction price of a contract is allocated to each performance obligation based on its relative standalone selling price. Standalone selling prices are generally determined based on the prices charged to customers or using the expected cost plus a margin. Shipping & Handling Costs The Company accounts for shipping and handling activities that occur after the transfer of control over the related goods as fulfillment activities rather than performance obligations. Shipping and handling fees charged to customers are recognized as revenue and the related costs are recorded in cost of revenue at the time of transfer of control. Warranties The standard warranty periods for the Company’s products are typically 12 months to 36 months. The Company recognizes estimated liabilities associated with standard warranty periods for its products in accordance with the provisions of ASC 450, “Contingencies,” as the Company has the ability to ascertain the likelihood of the liabilities and can reasonably estimate the amount of the liabilities. A provision for the estimated cost related to standard warranties is recorded as cost of revenue at the time revenue is recognized. The Company’s estimate of the costs to service the warranty obligations is based on historical experience and expectations of future conditions. To the extent that the Company’s experience in warranty claims or costs associated with servicing those claims differ from the original estimates, revisions to the estimated warranty liabilities are recorded at that time, with offsetting adjustments to cost of revenue. Practical Expedients and Exemptions The Company expenses incremental direct costs of obtaining a contract when incurred because the expected amortization period is typically one year or less. These costs are recorded within selling, general and administrative expenses in the consolidated statement of operations. The Company does not adjust the promised amount of consideration for the effects of a financing component because the transfer of a promised good to a customer and the customer’s payment for that good are typically one year or less. The Company does not disclose the value of the remaining performance obligation for contracts with an original expected length of one year or less. Contract Liabilities Contract liabilities consist of deferred revenue and advance payments from customers, including amounts that are refundable. These contract liabilities are classified as either current or long-term liabilities in the consolidated balance sheet based on the timing of when the Company expects to recognize the related revenue. As of June 30, 2023 and December 31, 2022, contract liabilities were $6.6 million and $8.4 million, respectively, and are included in accrued expenses and other current liabilities and other liabilities in the accompanying consolidated balance sheets. The decrease in the contract liability balance during the six months ended June 30, 2023 is primarily due to $5.3 million of revenue recognized during the period that was included in the contract liability balance as of December 31, 2022, partially offset by cash payments received in advance of satisfying performance obligations.
