Income Tax	9 Months Ended
Sep. 30, 2011
income tax disclosure [Abstract]
Income Tax	(9) Income Tax The Company has recorded a deferred tax asset in the amount of $20.5 million relating to the difference between its book and tax basis of its investment in the Partnership as of September 30, 2011 and December 31, 2010. Because the Company can only realize this deferred tax asset upon the liquidation of the Partnership and to the extent of capital gains, the Company has provided a full valuation allowance against this deferred tax asset. The income tax provision for the nine months ended September 30, 2011 reflects a tax benefit of $2.1 million for the current period loss. Unrecognized tax benefits increased $0.3 million during the nine months ended September 30, 2011, and the increase, if recognized, would affect the effective tax rate.

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.
