The effective rate is based on various factors including expected annual income, statutory tax rates, tax planning opportunities in the various jurisdictions in which the Company operates, permanent items, valuation allowances against deferred tax assets and the ability to utilize tax credits and net operating loss carryforwards. Subsequent recognition, derecognition and measurement of tax positions are separately recognized in the quarter in which the underlying transaction or event occurs which causes variability in the effective tax rates from quarter to quarter. The effective rate for each period differs from the U.S. federal statutory income tax rate due to the mix of earnings by jurisdiction and the effect of transaction costs and business combination accounting adjustments that do not provide tax benefits. Since the Company operates in multiple taxing jurisdictions at rates that are typically less than the U.S. statutory rate, the consolidated effective rate is typically lower than 35%. The valuation allowances also cause volatility in the effective rate as they reduce deferred tax assets in jurisdictions which lack sufficient positive evidence regarding the ability to utilize the assets and no tax benefit or expense is recognized for losses or income incurred in those jurisdictions. In accordance with Accounting Standards Codification 740 ("ASC 740"), the Company records interest and penalties associated with uncertain tax positions within income tax expense within the Company's Condensed Consolidated Statements of Operations. The Company does not have a material liability recorded for interest and penalties related to uncertain tax positions for any period presented.
