[1] The negative carrying value is due to the distributions of proceeds from a mortgage loan, as well as quarterly distributions of excess cash flow, exceeding the original contributions from the partners.
[2] Based on capital contribution and distribution provisions in the joint venture agreement, we expect our economic interest in the venture's cash flow to be greater than the ownership percentage indicated above, which in this case, states our legal interest in this venture. Our economic interest may fluctuate based on a number of factors, including mortgage financing, partnership capital contributions and distributions, and proceeds from gains or losses of asset sales.
