Contract Balances

The table below presents the contract assets and contract liabilities included on the consolidated balance sheets for the following periods:

​

The increase in contract assets was primarily driven by growth in revenue recognized and timing of billable milestones occurring during the Successor 2021 Period, and also by the acquisitions of Oakman, DPSS, and Techshot compared to December 31, 2020 before they were acquired.

The decrease in contract liabilities was related to timing of billable milestones occurring during the Successor 2021 Period, partially offset by an increase related to the acquisitions of Oakman and DPSS during the Successor 2021 Period ending December 31, 2021, compared to December 31, 2020 before they were acquired. Revenue recognized in the Successor 2021 Period that was included in the contract liability balance as of December 31, 2020 was $15.3 million.

The Company evaluates the contract value and cost estimates at completion (“EAC”) for performance obligations at least quarterly and more frequently when circumstances significantly change. Due to the nature of the work required to be performed on many of the Company’s performance obligations, the estimate of total revenue and cost at completion is complex, subject to many variables and requires significant judgment by management on a contract by contract basis. As part of this process, management reviews information including, but not limited to, labor productivity, the nature and technical complexity of the work to be performed, availability and cost volatility of materials, subcontractor and vendor performance, volume assumptions, inflationary trends, and schedule and performance delays. Management’s judgment related to these considerations has become increasingly more significant given the current economic environment primarily caused by the COVID-19 pandemic.

When the Company’s estimate of total costs to be incurred to satisfy a performance obligation exceeds the expected revenue, the Company recognizes the loss immediately. When the Company determines that a change in estimate has an impact on the associated profit of a performance obligation, the Company records the cumulative positive or negative adjustment to the statement of operations and comprehensive income (loss). Changes in estimates and assumptions related to the status of certain long-term contracts may have a material effect on the Company’s operating results.

The following table summarizes the impact of the net EAC adjustments for the periods presented:

Remaining Performance Obligations

As of December 31, 2021, the aggregate amount of the transaction price allocated to remaining performance obligations was $129.3 million. The Company expects to recognize approximately 78% of its remaining performance obligations as revenue within the next 12 months and the balance thereafter.
