Income Taxes
Income Taxes	11.Income Taxes The Company’s effective tax rate from continuing operations was 47.4% and 28.1% for the six months ended March 31, 2015 and 2014, respectively. The most significant items contributing to the difference between the statutory U.S. federal income tax rate of 35% and the Company’s effective tax rate for the six-month period ended March 31, 2015 were the impact of non-controlling income of interests in consolidated subsidiaries, state income tax benefits, the recognition of discrete items related to the extension of previously expired research and development credits and other energy related incentives, partially offset by an increase in certain non-deductible valuation allowances, transaction and other costs. As of the second quarter of fiscal 2015, the Company is utilizing the discrete-period method allowed by accounting standards codification to compute its interim tax provision due to significant variations in the relationship between income tax expense and pre-tax accounting income or loss; consequently, the actual effective rate for the interim period is being reported. The discrete-period method is applied when the application of the estimated annual effective tax rate is impractical because it is not possible to reliably estimate the annual effective tax rate. For the three-month periods ended December 31, 2014 and 2013 and the six-month period ended March 31, 2014, the Company utilized the estimated annual effective tax rate method in computing its interim tax provisions. The relationship between pre-tax accounting income and income tax for these periods allowed the Company to estimate the annual effective tax rate to be applied to year-to-date income in those periods. The Company’s effective tax rate fluctuates from quarter to quarter due to various factors including the change in the mix of global income, tax law changes, outcomes of administrative audits, changes in the assessment of valuation allowances and other tax contingencies. The Company believes the outcomes which are reasonably possible within the next twelve months, including lapses in statutes of limitations, will not result in a material change in the liability for uncertain tax positions. Generally, the Company does not provide for U.S. taxes or foreign withholding taxes on undistributed earnings from non-U.S. subsidiaries because such earnings are able to and intended to be reinvested indefinitely. Determination of the amount of any unrecognized deferred income tax liability on this temporary difference is not practicable because of the complexities of the hypothetical calculation. The Company recorded a deferred tax liability in the amount of $108.9 million relating to certain foreign subsidiaries for which the undistributed earnings are not intended to be reinvested indefinitely as part of the liabilities assumed in connection with the acquisition of URS on October 17, 2014.
