| Summarized Balance Sheets for Unconsolidated Investments           | Summarized financial information for the unconsolidated investments on a combined basis is as follows:  December 31, 2014 December 31,2013BALANCE SHEETS:   Investment in real estate$— $12,124Cash and cash equivalents15,461 16,897Other assets57 72Total assets$15,518 $29,093    Accounts payable and other liabilities$605 $159Equity(1)14,913 28,934Total liabilities and equity$15,518 $29,093 (1)  The majority of the equity in unconsolidated investments relates to ALP. In 2008, the Company wrote-off its investment in ALP as a result of ALP reserving its assets to satisfy potential claims and obligations in accordance with its publicly reported liquidation basis of accounting. Subsequently, ALP changed its method of accounting to a going concern basis and reinstated its equity and stated it would report certain expenses as they are incurred. The Company has not recorded any additional equity income as a result of the ALP’s change in accounting. |
