Income Taxes	Note 15—Income Taxes The effective tax rate for the nine months ended September 30, 2015 for income before taxes and noncontrolling interests is 38.3% and for income attributable to Primoris is 38.4%. The rate differs from the U.S. federal statutory rate of 35% due primarily to state income taxes, the “Domestic Production Activity Deduction” and nondeductible meals and incidental per diems common in the construction industry. To determine its quarterly provision for income taxes, the Company uses an estimated annual effective tax rate, which is based on expected annual income, statutory tax rates and tax planning opportunities available in the various jurisdictions in which the Company operates. Certain significant or unusual items are separately recognized in the quarter in which they occur and can be a source of variability in the effective tax rate from quarter to quarter. The Company recognizes interest and penalties related to uncertain tax positions, if any, as an income tax expense. Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences of temporary differences between the financial reporting basis and tax basis of the Company’s assets and liabilities. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period of enactment date. In the third quarter of 2014, the Internal Revenue Service concluded an examination of our federal income tax returns for 2011 and 2012 which did not have a material impact on our financial statements. The Company’s federal income tax returns are no longer subject to examination for tax years before 2013. The statutes of limitation of state and foreign jurisdictions vary generally between 3 to 5 years. Accordingly, the tax years 2009 through 2014 generally remain open to examination by the other taxing jurisdictions in which the Company operates.
