4.    INVESTMENTS IN UNCONSOLIDATED JOINT VENTURES

As of June 30, 2019, the Company had an aggregate investment of approximately $216 million in its equity method joint ventures. The Company formed these ventures with unaffiliated third parties, or acquired interests in them, to develop or manage primarily office and multi-family rental properties, or to acquire land in anticipation of possible development of office and multi-family rental properties. As of June 30, 2019, the unconsolidated joint ventures owned: two office properties aggregating approximately 0.2 million square feet, seven multi-family properties totaling 2,611 apartments units, two retail properties aggregating approximately 81,700 square feet, a 351-room hotel, a development project for up to approximately 360 apartments units; and interests and/or rights to developable land parcels able to accommodate up to 3,738 apartments units. The Company’s unconsolidated interests range from 20 percent to 85 percent subject to specified priority allocations in certain of the joint ventures.

The amounts reflected in the following tables (except for the Company’s share of equity in earnings) are based on the historical financial information of the individual joint ventures. The Company does not record losses of the joint ventures in excess of its investment balances unless the Company is liable for the obligations of the joint venture or is otherwise committed to provide financial support to the joint venture. The outside basis portion of the Company’s investments in joint ventures is amortized over the anticipated useful lives of the underlying ventures’ tangible and intangible assets acquired and liabilities assumed. Unless otherwise noted below, the debt of the Company’s unconsolidated joint ventures generally is non-recourse to the Company, except for customary exceptions pertaining to such matters as intentional misuse of funds, environmental conditions, and material misrepresentations.

The Company has agreed to guarantee repayment of a portion of the debt of its unconsolidated joint ventures. As of June 30, 2019, such debt had a total borrowing capacity of up to $317.1 million of which the Company agreed to guarantee up to $35.8 million. As of June 30, 2019, the outstanding balance of such debt totaled $211.2 million of which $25.2 million was guaranteed by the Company. The Company performed management, leasing, development and other services for the properties owned by the unconsolidated joint ventures and recognized $0.5 million and $0.6 million for such services in the three months ended June 30, 2019 and 2018, respectively. The Company had $0.2 million in accounts receivable due from its unconsolidated joint ventures as of both June 30, 2019 and December 31, 2018.

Included in the Company’s investments in unconsolidated joint ventures as of June 30, 2019 are four unconsolidated development joint ventures, which are VIEs for which the Company is not the primary beneficiary. These joint ventures are primarily established to develop real estate property for long-term investment and were deemed VIEs primarily based on the fact that the equity investment at risk was not sufficient to permit the entities to finance their activities without additional financial support. The initial equity contributed to these entities was not sufficient to fully finance the real estate construction as development costs are funded by the partners throughout the construction period. The Company determined that it was not the primary beneficiary of these VIEs based on the fact that the Company has shared control of these entities along with the entity’s partners and therefore does not have controlling financial interests in these VIEs. The Company’s aggregate investment in these VIEs was approximately $119.7 million as of June 30, 2019. The Company’s maximum exposure to loss as a result of its involvement with these VIEs is estimated to be approximately $155.5 million, which includes the Company’s current investment and estimated future funding commitments/guarantees of approximately $35.8 million. The Company has not provided financial support to these VIEs that it was not previously contractually required to provide. In general, future costs of development not financed through third parties will be funded with capital contributions from the Company and its outside partners in accordance with their respective ownership percentages.
