Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company files a consolidated federal income tax return. Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The Company's effective tax rate during the nine months ended September 30, 2014 was 13.4% of earnings from continuing operations before income taxes. This differs from the federal statutory income tax rate of 35.0% primarily due to the exclusion of the noncontrolling interests’ share of pre-tax earnings, the impact of state income taxes and the non-deductibility for tax purposes of certain transaction costs resulting from the Sheridan transaction. The Company applies recognition thresholds and measurement attributes for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return as it relates to accounting for uncertainty in income taxes. In addition, it is the Company’s policy to recognize interest accrued and penalties, if any, related to unrecognized benefits as income tax expense in its consolidated statement of operations. The Company does not expect significant changes to its tax positions or liability for tax uncertainties during the next 12 months. The Company and its subsidiaries file U.S. federal and various state tax returns. With few exceptions, the Company is no longer subject to U.S. federal or state income tax examinations for years prior to 2011.
