Progress billings in accounts receivable at December 31, 2016 and June 30, 2016 included retentions to be collected within one year of $51.4 million and $29.7 million, respectively. Contract retentions collectible beyond one year are included in other assets in the condensed consolidated balance sheet and totaled $0.3 million as of June 30, 2016. There were no retentions collectible beyond one year as of December 31, 2016. Other Under percentage of completion accounting for fixed-priced contracts, contract revenues and earnings are recognized ratably over the contract term based on the proportion of actual costs incurred to total estimated costs. As of December 31, 2016, the Company is performing work on two previously announced significant multi-year projects that are contracted on a fixed price basis. The first project is expected to complete in fiscal 2017 and revenue will continue to decline as this project nears completion. The second project is expected to be completed in fiscal 2018. On the project that is expected to be completed in fiscal 2018, the Company executed a change order in the second quarter that settled the claims outstanding on the effective date of the change order, updated the project schedule, and increased the contract value to allow for the recovery of increased costs. The settlement resulted in a second quarter reduction in earnings related to adjusting the gross profit margin and the percent complete on the project due to the increased project size. In addition, the change order contained provisions that require the achievement of defined schedule milestones to earn a portion of the additional contract value. At December 31, 2016, the Company’s schedule assessment indicates that it is probable that these schedule milestones will be achieved. Although this change order reduced the financial risk inherent in this project, it is possible that future changes in contract estimates, including those related to project costs, project timeline, and future change orders or claims, could occur and have a material positive or negative impact to our results of operations and financial position in subsequent accounting periods.
