Income Tax Disclosure [Abstract] |
Income Taxes | INCOME TAXES Our effective tax rate was 36 percent and 34 percent for the three-month and six-month periods ended June 30, 2016, respectively. Our rate for the six-month period ended June 30, 2016 included a $4 million state income tax benefit on uncertain tax positions resulting from the expiration of applicable statutes of limitation. Our effective tax rate was 46 percent and 43 percent for the three-month and six-month periods ended June 30, 2015, respectively, primarily due to an $18 million valuation allowance against the deferred tax assets of TopBuild recorded as a non-cash charge to income tax expense in the second quarter of 2015. The TopBuild deferred tax assets have been impaired by our decision to spin off TopBuild into a separate company that on a stand-alone basis as of June 30, 2015, the spin off date, was unlikely to be able to realize the value of such deferred tax assets as a result of its history of losses.
