Costs to fulfill contract assets relate to deferred costs, which are included within other current assets and or other assets, and software development costs, which are included within property and equipment, in our condensed consolidated balance sheets. Changes in contract liabilities during the period decreased $1.2 million from December 31, 2018 to June 30, 2019 , primarily due to an increase of approximately $4.4 million from new projects, offset by approximately $5.6 million of amortization and recognition of revenue in the six months ended June 30, 2019 . Contract losses recognized for the six months ended June 30, 2019 were not material. Accrued contract liabilities below are included within accrued expenses in our condensed consolidated balance sheets. The timing of revenue recognition, billings and cash collections results in billed accounts receivable, unbilled receivables, and customer advances and deposits (contract liabilities) on the condensed consolidated balance sheets. Changes in the contract asset and liability balances during the six months ended June 30, 2019 were not materially impacted by any other factors. Contract balances consist of the following (in thousands): June 30, 2019 December 31, 2018 Contract Assets Trade accounts receivable, net $ 52,562 $ 72,180 Unbilled accounts receivable 354 235 Costs to fulfill 4,480 5,214 Total contract assets $ 57,396 $ 77,629 Contract Liabilities Accrued contract liabilities $ 1,094 $ 535 Deferred revenue 7,491 9,255 Total contract liabilities $ 8,585 $ 9,790 Remaining performance obligations represent the transaction price of firm orders for which work has not yet been performed. This amount does not include 1) contracts that are less than one year in duration, 2) contracts for which we recognize revenue based on the right to invoice for services performed, or 3) variable consideration allocated entirely to a wholly unsatisfied performance obligation. Much of our revenue qualifies for one of these exemptions. As of June 30, 2019 , the aggregate amount of the transaction price allocated to remaining performance obligations for contracts with an original expected duration of one year or more was $ 19.3 million. We expect to recognize revenue on approximately 62% of the remaining performance obligations in 2019, 29% in 2020, and the remaining recognized thereafter. |
