Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Income tax expense was $815,000 and $3,931,000 for the three months ended March 31, 2015 and 2014, respectively. The difference in recorded income tax expense/benefit versus income tax expense/benefit computed at the statutory federal income tax rate is primarily attributable to state income taxes, changes in state net operating losses, additional general business credits, changes to valuation allowances associated with certain deferred tax assets, and various permanent differences between pre-tax GAAP income and taxable income. The most significant permanent difference during the three months ended March 31, 2015 was the loss on extinguishment of debt recorded in connection with the privately negotiated exchanges of a portion of the Company’s Senior Notes. At December 31, 2014, the Company had a federal net operating loss carryforward for tax purposes of $307,200,000 expiring in the years ending December 31, 2029 through 2034, a charitable contribution deduction carryforward of $16,234,000 expiring in the years ending December 31, 2015 through 2019, General business credit carryovers of $36,779,000 expiring in the years ending December 31, 2018 through 2034, and an alternative minimum tax (“AMT”) credit carryforward of $27,452,000 that is available until used to reduce federal tax to the AMT amount. If the Company converts to REIT status, it is anticipated certain subsidiaries may be treated as taxable REIT subsidiaries and would continue to be subject to corporate income taxes. In addition, the Company could be subject to corporate income taxes related to assets sold during the 10-year period following the date of conversion, to the extent such assets had a built-in gain on the date of conversion.
