Revenues are recognized as performance obligations are satisfied over time (also known as percentage-of-completion method), measured by the ratio of costs incurred up to a given date to estimated total costs for each contract. This cost to cost measure is used because management considers it to be the best available measure of progress on these contracts. Contract costs include all direct material, labor, subcontract and other costs and those indirect costs determined to relate to contract performance, such as indirect salaries and wages, equipment repairs and depreciation, insurance and payroll taxes. Administrative and general expenses are charged to expense as incurred. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined. Changes in job performance, job conditions, estimated profitability and associated change orders and claims, including those changes arising from contract penalty provisions and final contract settlements, may result in revisions to costs and income and are recognized in the period in which the revisions are determined.</font><font style="font-family:inherit;font-size:10pt;"> </font></div><div style="line-height:120%;padding-bottom:2px;padding-top:6px;text-align:justify;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;">Residential Construction</font></div><div style="line-height:120%;padding-bottom:2px;padding-top:6px;text-align:justify;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Residential construction revenue and related profit are recognized when construction on the concrete foundation unit is completed (i.e., at a point in time). The time from starting construction to finishing is typically less than one month.</font></div></div>

Certain of the Company’s accounting policies require higher degrees of judgment than others in their application. These include among other things the recognition of revenue and earnings from construction contracts over time, the valuation of long-term assets, income taxes, purchase accounting, intangibles and goodwill. Management continually evaluates all of its estimates and judgments based on available information and experience; however, actual results could differ from these estimates. </font></div></div>
