Income Taxes	10.Income Taxes The Company’s effective tax rate from continuing operations was (18.6)% and 49.7% for the nine months ended June 30, 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 nine-month period ended June 30, 2016 were the recognition of a discrete benefit of $11.7 million related to the retroactive extension of previously expired research and development credits enacted during the first quarter and other energy-related incentives, a $15.3 million benefit related to non-controlling interests, $38.4 million benefit related to valuation allowances in the United Kingdom and Australia, 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 $7.2 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 (71.2)% and 97.2% for the three months ended June 30, 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 June 30, 2016 were the recognition of a benefit of $38.4 million related to the release of valuation allowances in the United Kingdom and Australia and a $6.9 million benefit related to non-controlling interests. Based on a review of positive and negative evidence available to us, the Company has previously recorded valuation allowances against our deferred tax assets in the United Kingdom, Canada and Australia to reduce them to the amount that in our judgment is more likely than not realizable. Certain valuation allowances in the amount of $26.5 million in the United Kingdom have been released due to sufficient positive evidence obtained during the third quarter of 2016. Our United Kingdom affiliate evaluated the new positive evidence against any negative evidence and determined the valuation allowance was no longer necessary. This new positive evidence includes reaching a position of cumulative income over a three year period and the use of net operating losses on a taxable basis. In addition, our United Kingdom affiliate has strong projected earnings in the United Kingdom. During the third quarter of 2016, our Australian affiliate made an election in Australia to combine the tax results of the URS Australia business with the AECOM Australia business. This election resulted in the ability to utilize the URS Australia businesses’ deferred tax assets and accordingly, the valuation allowance of $11.9 million was released. In the third 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 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 third quarter of 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.
