Note 6 Contracts in Progress
Accounts payable includes retainage due to subcontractors totaling $11.1 million and $8.9 million as of December 31, 2017 and 2016, respectively.
The Company has asserted claims and may have unresolved change orders on certain construction projects. These occur typically as a result of scope changes and project delays. Management continually evaluates these items and estimates the recoverable amounts and, if significant, these recoverability estimates are evaluated to determine the net realizable value. If additional amounts are recovered, additional contract revenue would be recognized. The current estimated net realizable value on such items as recorded in costs and estimated earnings in excess of billings on uncompleted contracts in the consolidated balance sheets was $10.3 million and $7.9 million as of December 31, 2017 and 2016, respectively. The Company anticipates that the majority of such amounts will be earned as revenue within one year.
