Organization, Consolidation and Presentation of Financial Statements [Abstract]
Variable Interest Entities	Variable Interest Entities At third quarter-end 2013, we are the primary beneficiary of one variable interest entity (VIE) that we consolidate. At third quarter-end 2013, our consolidated balance sheet includes no assets and $1,342,000 in liabilities related to this VIE. In first nine months 2013, there were no contributions to this VIE. Also at third quarter-end 2013, we are not the primary beneficiary of three VIEs that we account for using the equity method. The unrelated managing partners oversee day-to-day operations and guarantee some of the debt of the VIEs, and while we have certain rights regarding major decisions, we do not have the power to direct the activities that are most significant to the economic performance of the entities. Although some of the debt is guaranteed by the managing partners, we may under certain circumstances elect or be required to provide additional funds to these VIEs. At third quarter-end 2013, these three VIEs have total assets of $11,079,000, substantially all of which represent developed and undeveloped real estate, and total liabilities of $44,541,000, which includes $27,902,000 of borrowings classified as current maturities. These amounts are included in other ventures in the combined summarized balance sheet information for ventures accounted for using the equity method in Note 7 — Investment in Unconsolidated Ventures. At third quarter-end 2013, our investment in these VIEs is $18,000 and is included in investment in unconsolidated ventures. In first nine months 2013, we contributed $111,000 to these VIEs. Our maximum exposure to loss related to these VIEs is estimated at $3,730,000, which exceeds our investment as we have a nominal general partner interest in all of these VIEs and could be held responsible for their liabilities. The maximum exposure to loss represents the maximum loss that we could be required to recognize assuming all the ventures’ assets (principally real estate) are worthless, without consideration of the probability of a loss or of any actions we may take to mitigate any such loss.
