Income Tax Disclosure [Abstract] |
Income tax | NOTE 10. INCOME TAX The Company's effective income tax rate from continuing operations for the three and nine months ended May 31, 2015 was 36.1% and 33.5%, respectively, compared with 35.9% and 31.4% for the three and nine months ended May 31, 2014, respectively. For the three months ended May 31, 2015, the tax rate is higher than the statutory income tax rate of 35% due to losses in certain foreign jurisdictions where the deferred tax assets created by such losses are subject to a full valuation allowance, thus providing no tax benefit for such losses. For the nine months ended May 31, 2015, the tax rate was lower than the statutory income tax rate of 35% because the Company had income from operations in countries which have lower tax rates than the United States. In addition, the Company benefited under Section 199 of the Internal Revenue Code related to domestic production activity income during the three and nine months ended May 31, 2015. The Company's effective income tax rate from discontinued operations for the three and nine months ended May 31, 2015 was 3.9% and 2.2%, respectively, compared with 13.1% and 48.8% for the three and nine months ended May 31, 2014, respectively. The Company's effective income tax rate from discontinued operations for the three and nine months ended May 31, 2015 reflected the fact that earnings from discontinued operations before income taxes included a loss in Australia, a jurisdiction in which all tax losses created a deferred tax asset that was subject to a full valuation allowance, and thus no tax benefit. The Company's effective income tax rate from discontinued operations for the nine months ended May 31, 2014 reflected a $23.8 million pre-tax gain on the sale of Howell, resulting in the appropriate amount of U.S. federal and state income tax expense. The Company made net payments of $46.7 million and $12.9 million for income taxes during the nine months ended May 31, 2015 and 2014, respectively. As of both May 31, 2015 and August 31, 2014, the reserve for unrecognized income tax benefits related to the accounting for uncertainty in income taxes was $27.3 million, exclusive of interest and penalties. The Company's policy classifies interest recognized on an underpayment of income taxes and any statutory penalties recognized on a tax position as income tax expense, and the balances at the end of a reporting period are recorded as part of the current or noncurrent reserve for uncertain income tax positions. For the three and nine months ended May 31, 2015, before any income tax benefits, the Company recorded immaterial amounts of accrued interest and penalties on unrecognized income tax benefits. During the twelve months ending May 31, 2016, it is reasonably possible that the statute of limitations pertaining to positions taken by the Company in prior year income tax returns may lapse or that income tax audits in various taxing jurisdictions could be finalized. As a result, the total amount of unrecognized income tax benefits may decrease by approximately $16.9 million, which would reduce the provision for income taxes by $2.7 million. The Company files income tax returns in the United States and multiple foreign jurisdictions with varying statutes of limitations. In the normal course of business, CMC and its subsidiaries are subject to examination by various taxing authorities. The following is a summary of tax years subject to examination: U.S. Federal — 2009 and forward U.S. States — 2009 and forward Foreign — 2007 and forward The Company is currently under examination by the Internal Revenue Service and state revenue authorities from 2009 to 2011. Management believes the Company's recorded tax liabilities as of May 31, 2015 sufficiently reflect the anticipated outcome of these examinations.
