Variable Interest Entities	NOTE 5 — Variable Interest Entities As of September 30, 2013, we were the primary beneficiary of, and therefore consolidated, 66 VIEs, which owned 52 properties with 8,100 apartment homes. Real estate with a carrying value of $420.1 million collateralized $374.4 million of debt of those VIEs. Any significant amounts of assets and liabilities related to our consolidated VIEs are identified parenthetically on our accompanying condensed consolidated balance sheets. The creditors of the consolidated VIEs do not have recourse to our general credit. As of September 30, 2013, we also held variable interests in 39 VIEs for which we were not the primary beneficiary. Those VIEs consist primarily of partnerships that are engaged, directly or indirectly, in the ownership and management of 92 properties with 2,360 apartment homes. We are involved with those VIEs as an equity holder or lender. Our maximum risk of loss related to our investments in or lending activities related to these unconsolidated VIEs is generally limited to our investments in or receivables from such entities. At September 30, 2013, our recorded investment in these entities totaled $4.0 million and is included in other assets within our condensed consolidated balance sheets. Additionally, at September 30, 2013, we had in aggregate $215.6 million of receivables from these unconsolidated VIEs (primarily notes receivable collateralized by first and second mortgages on real estate properties discussed in Note 4). We may be subject to additional losses to the extent of any receivables relating to future provision of services to these entities or financial support that we voluntarily provide. In addition to the consolidated and unconsolidated VIEs discussed above, at September 30, 2013, our consolidated financial statements included certain consolidated and unconsolidated VIEs that were sold in connection with the sale of our legacy asset management business.
