Costs to Fulfill a Contract

Costs to fulfill a contract are included in "Prepaid expenses and other current assets" on the Consolidated Balance Sheet and amounted to $5,835,000 and $3,963,000 as of March 29, 2020 and December 31, 2019, respectively.

Accounts Receivable, Contract Assets, and Contract Liabilities

Accounts receivable represent amounts billed and currently due from customers which are reported at their net estimated realizable value. The Company maintains an allowance against its accounts receivable for potential credit losses. Contract assets consist of unbilled revenue which arises when revenue is recognized in advance of billing for

certain application-specific customer solutions contracts. Contract liabilities consist of deferred revenue and customer deposits which arise when amounts are billed to or collected from customers in advance of revenue recognition.

On January 1, 2020, the Company adopted Accounting Standards Update (ASU) 2016-13, “Measurement of Credit Losses on Financial Instruments,” using the modified-retrospective approach, which requires the Company to apply the standard on a prospective basis with a cumulative-effect adjustment to retained earnings as of the beginning of the period in which the guidance is effective. The Company did not record an adjustment to retained earnings as this ASU did not have a material impact on the Company's consolidated allowance for credit losses.

The Company recorded credit losses on accounts receivable of $300,000 for the three-month period ended March 29, 2020. No credit losses on accounts receivables were recorded during the three-month period ended March 31, 2019.
