Contracts with Customers

Unbilled receivables decreased from $10,025 at December 31, 2018 to $9,043 at December 31, 2019, primarily driven by timing of billings at BDS and BGS.

Advances and progress billings increased from $50,676 at December 31, 2018 to $51,551 at December 31, 2019, primarily driven by advances on orders received in excess of revenue recognized at BDS, BGS, and BCA.

Revenues recognized for the years ended December 31, 2019 and 2018 from amounts recorded as Advances and progress billings at the beginning of each year were $16,778 and $24,737.

Certain commercial airplane customers are experiencing liquidity issues and seeking additional capital. Should these customers fail to address their liquidity issues, accounts receivable, unbilled receivables and certain inventory could become impaired. In addition we would have to remove contracts related to these customers from backlog and remarket any undelivered aircraft.

The following table summarizes our contract assets under long-term contracts that were unbillable or related to outstanding claims as of December 31:

Unbilled receivables related to commercial customer incentives expected to be collected after one year were $211 and $150 at December 31, 2019 and 2018. Unbilled receivables related to claims are items that we believe are earned, but are subject to uncertainty concerning their determination or ultimate realization.
