Income Taxes	10.Income Taxes The Company’s effective tax rate from continuing operations was 14.8% and 47.4% for the six months ended March 31, 2016 and 2015, 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, 2016 were the recognition of a discrete benefit of $12.3 million related to the retroactive extension of previously expired research and development credits enacted during the first quarter and other energy-related incentives, an $8.4 million benefit related to non-controlling interests, partially offset by the impact of current year losses primarily in Canada, South Africa, and India for which no tax benefit is expected due to valuation allowances of $3.9 million, and a $3.8 million discrete expense, net of related valuation allowance, due to the reduction in the United Kingdom statutory income tax rate during the first quarter. The Company’s effective tax rate from continuing operations was 15.5% and 137.3% for the three months ended March 31, 2016 and 2015, 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 three-month period ended March 31, 2016 were the recognition of a benefit of $5.9 million related to research and development credits and other energy-related incentives and an $8.5 million benefit related to non-controlling interests. In the second quarter of 2016, the Company is utilizing the annual effective tax rate method under ASC 740 to compute its interim tax provision. The Company’s effective tax rate fluctuates from quarter to quarter due to various factors including the change in the mix of global income, outcomes of administrative audits, changes in the assessment of valuation allowances due to management’s consideration of new positive or negative evidence during the quarter, and changes in enacted tax laws and their interpretations which upon enactment include possible tax reform contemplated in the United States and other jurisdictions around the world arising from the result of the base erosion and profit shifting (BEPS) project undertaken by the Organisation for Economic Co-operation Development (OECD) which, if finalized and adopted, could have a material impact on the Company’s income tax expense and deferred tax balances. In the second quarter of fiscal 2015, the Company utilized the discrete-period method under ASC 740 to compute its interim income tax provision due to significant variations in the relationship between the income tax expense and the pre-tax loss. 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. 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 has a deferred tax liability in the amount of $97.3 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. In November 2015, the FASB issued new accounting guidance which simplifies the presentation of deferred income taxes. This guidance requires that deferred tax assets and liabilities be classified as noncurrent in the balance sheet. The Company has elected early adoption of this standard on a prospective basis in the first quarter of 2016. This resulted in a reclassification of the Company’s net current deferred tax asset and net current deferred tax liability to the net non-current deferred tax asset and to its net non-current deferred tax liability in the Company’s consolidated balance sheet as of December 31, 2015. No prior periods were retrospectively adjusted. The adoption of this guidance had no impact on the Company’s consolidated results of income or comprehensive income.
