Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES Our effective tax rate, exclusive of noncontrolling interests, for each of the three and six months ended June 30, 2016 was 38.0%. Our effective tax rate, exclusive of noncontrolling interests, for the three and six months ended June 30, 2015 was 36.3% and 37.8%, respectively. The effective tax rate for the three and six months ended June 30, 2016 was favorably affected by the resolution of state and federal tax matters. The effective tax rate for the three and six months ended June 30, 2015 was favorably affected by the resolution of a Puerto Rican tax matter.

When determining the need for a valuation allowance, we consider all positive and negative evidence, including recent financial results, scheduled reversals of deferred tax liabilities, projected future taxable income and tax planning strategies. The weight given to the positive and negative evidence is commensurate with the extent such evidence can be objectively verified. We adjust the valuation allowance in the period management determines it is more likely than not that deferred tax assets will or will not be realized. Substantially all of our valuation allowance is associated with state loss carryforwards. The realization of our deferred tax asset for state loss carryforwards ultimately depends upon the existence of sufficient taxable income in the appropriate state taxing jurisdictions in future periods.
