Income Tax Disclosure [Abstract] |
INCOME TAXES | INCOME TAXES The Company’s income tax expense for the three and nine months ended June 30, 2016 was $128.8 million and $317.8 million, respectively, compared to $112.4 million and $272.8 million, respectively, in the same periods of fiscal 2015. The effective tax rate was 34.0% and 34.5% for the three and nine months ended June 30, 2016, respectively, compared to 33.7% and 34.8% in the prior year periods. The effective tax rates for all periods include an expense for state income taxes that was reduced by a tax benefit for the domestic production activities deduction and federal energy tax credits. At June 30, 2016 and September 30, 2015, the Company had deferred tax assets, net of deferred tax liabilities, of $514.3 million and $568.2 million, respectively, partially offset by valuation allowances of $9.2 million and $10.1 million, respectively. The accounting for deferred taxes is based upon estimates of future results. Differences between the anticipated and actual outcomes of these future results could have a material impact on the Company’s consolidated results of operations or financial position. Also, changes in existing federal and state tax laws and tax rates could affect future tax results and the valuation of the Company’s deferred tax assets. When assessing the realizability of deferred tax assets, the Company considers whether it is more likely than not that some portion or all of its deferred tax assets will not be realized. The realization of deferred tax assets is dependent upon the generation of sufficient taxable income in future periods. The Company records a valuation allowance when it determines it is more likely than not that a portion of the deferred tax assets will not be realized. The valuation allowance for both periods relates to the Company’s state deferred tax assets for net operating loss (NOL) carryforwards. The valuation allowance as of September 30, 2015 also relates to certain state tax credit carryforwards. As of June 30, 2016, the Company believes it is more likely than not that a portion of its state NOL carryforwards will not be realized because some state NOL carryforward periods are too brief to realize the related deferred tax assets. The Company will continue to evaluate both the positive and negative evidence in determining the need for a valuation allowance with respect to its remaining state NOL carryforwards.
