Revisions in Estimates [Abstract]

Revision in Estimate Method [Policy Text Block]

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. We do not recognize revenue on contract change orders or affirmative claims until we have a signed agreement; however, we do recognize costs as incurred and revisions to estimated total costs as soon as the obligation to perform is determined. Approved change orders and affirmative claims, as well as changes in related estimates of costs to complete, are considered revisions in estimates. 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.
