Revision in Estimates

Our profit recognition related to construction contracts is based on estimates of costs to complete each project. These estimates can vary significantly in the normal course of business as projects progress, circumstances develop and evolve, and uncertainties are resolved. When we experience significant changes in our estimates of costs to complete, we undergo a process that includes reviewing the nature of the changes to ensure that there are no material amounts that should have been recorded in a prior period rather than as revisions in estimates for the current period. In our review of these changes for the three and six months ended June 30, 2016 and 2015, we did not identify any material amounts that should have been recorded in a prior period. We use the cumulative catch-up method applicable to construction contract accounting to account for revisions in estimates. Under this method, revisions in estimates are accounted for in their entirety in the period of change. There can be no assurance that we will not experience further changes in circumstances or otherwise be required to further revise our cost estimates.

Revenue in an amount equal to cost incurred is recognized if there is not sufficient information to determine the estimated profit on the project with a reasonable level of certainty.

Construction Joint Ventures

We have determined that certain of these joint ventures are consolidated because they are variable interest entities (“VIEs”), and we are the primary beneficiary. We continually evaluate whether there are changes in the status of the VIEs or changes to the primary beneficiary designation of the VIE.
