Contract Balances

Billed receivables, unbilled receivables (contract assets), and contract liabilities are the results of revenue recognition, customer billing, and timing of payment receipts. Billed receivables, net, represent unconditional rights to consideration under the terms of the contract and include amounts billed and currently due from our customers. Unbilled receivables represent our right to consideration in exchange for goods or services that we have transferred to the customer prior to us having the right to payment for such goods or services. Contract liabilities are recorded when customers remit contractual cash payments in advance of us satisfying related performance obligations under contractual arrangements, including those with performance obligations to be satisfied over a period of time.

We present our unbilled receivables and contract liabilities on a contract-by-contract basis. If a contract liability exists, it is netted against the unbilled receivables balance for that contract. Unbilled receivables increased from $41.3 million at December 31, 2018 to $46.0 million at June 30, 2019, primarily due to revenue recognized in excess of billings. Contract liabilities, which are included in accrued expenses and other current liabilities in our consolidated balance sheet, decreased from $5.0 million at December 31, 2018 to $4.9 million at June 30, 2019, primarily due to revenue recognized in excess of advance payments received. For the six months ended June 30, 2019 and June 30, 2018, we recognized revenue that was previously included in the beginning balance of contract liabilities of $2.0 million and $7.7 million, respectively.

Performance Obligations

Our performance obligations are satisfied over time as work progresses or at a point in time. Revenues from products and services transferred to customers over time accounted for approximately 57% of our revenues for the three and six months ended June 30, 2019 and June 30, 2018, primarily related to revenues in our Federal Services Group and for MRO services in our Aviation Group. Revenues from products and services transferred to customers at a point in time accounted for approximately 43% of our revenues for the three and six months ended June 30, 2019 and June 30, 2018. The majority of our revenue recognized at a point in time is for the sale of vehicle and aircraft parts in our Supply Chain Management and Aviation groups.

As of June 30, 2019, the aggregate amount of transaction prices allocated to unsatisfied or partially unsatisfied performance obligations was $269 million. Performance obligations expected to be satisfied within one year and greater than one year are 97% and 3%, respectively. We have applied the practical expedient for certain parts sales and MRO services to exclude the amount of remaining performance obligations for (i) contracts with an original expected term of one year or less or (ii) contracts for which we recognize revenue in proportion to the amount we have the right to invoice for services performed.

During the six months ended June 30, 2019 and June 30, 2018, revenue recognized from performance obligations satisfied in prior periods was not material.
