Consolidation Policy for VIEs	Variable Interest Entities Partnership As the result of the adoption of ASU 2015-02, which stipulates that limited partnerships (and similar entities) where the limited partners do not have substantive participating or kick-out rights are VIEs, we determined that the Partnership is a VIE. Prior to the adoption of ASU 2015-02, the General Partner consolidated the Partnership pursuant to the voting interest model. We concluded that, because it holds majority ownership and exercises control over every aspect of the Partnership's operations, the General Partner is the primary beneficiary of the Partnership and, as such, will continue to consolidate the Partnership. The assets and liabilities of the General Partner and the Partnership are substantially the same, as the General Partner does not have any significant assets other than its investment in the Partnership. All of the Company's debt is also an obligation of the Partnership. Unconsolidated Joint Ventures We have equity interests in unconsolidated joint ventures that primarily own and operate rental properties or hold land for development. We consolidate those joint ventures that are considered to be VIEs where we are the primary beneficiary. We analyze our investments in joint ventures to determine if the joint venture is considered a VIE and would require consolidation. We (i) evaluate the sufficiency of the total equity investment at risk, (ii) review the voting rights and decision-making authority of the equity investment holders as a group and whether there are limited partners (or similar owning entities) that lack substantive participating or kick out rights, guaranteed returns, protection against losses, or capping of residual returns within the group and (iii) establish whether activities within the venture are on behalf of an investor with disproportionately few voting rights in making this VIE determination. To the extent that we own interests in a VIE and we (i) are the sole entity that has the power to direct the activities of the VIE and (ii) have the obligation or rights to absorb the VIE's losses or receive its benefits, then we would be determined to be the primary beneficiary and would consolidate the VIE. To the extent we own interests in a VIE, then at each reporting period, we re-assess our conclusions as to which, if any, party within the VIE is considered the primary beneficiary. There were no unconsolidated joint ventures, in which we have any recognized assets or liabilities or have retained any economic exposure to loss at June 30, 2016 that met the criteria to be considered VIEs. Our maximum loss exposure for guarantees of joint venture indebtedness, none of which relate to VIEs, totaled $75.5 million at June 30, 2016.

Disclosure of accounting policy for consolidation to describe the significant judgments and assumptions made in determining whether a variable interest held by the entity requires the variable interest entity to be consolidated and (or) disclose information about its involvement with the variable interest entity; the methodology used by the entity for determining whether or not it is the primary beneficiary of the variable interest entity; and the significant factors considered and judgments made in determining that the power to direct the activities that significantly impact the economic performance of the variable interest entity are shared (as defined).
