Related Parties	Related Parties Through our management activities and transactions with our real estate joint ventures and partnerships, we had net accounts receivable of $1.3 million and $2.2 million outstanding as of September 30, 2017 and December 31, 2016, respectively. We also had accounts payable and accrued expenses of $.4 million and $.3 million outstanding as of September 30, 2017 and December 31, 2016, respectively. We recorded joint venture fee income included in Other Revenue for the three months ended September 30, 2017 and 2016 of $1.4 million and $1.2 million, respectively, and $4.4 million and $3.5 million for the nine months ended September 30, 2017 and 2016, respectively. In September 2016, we acquired a partner's 50% interest in an unconsolidated tenancy-in-common arrangement for approximately $13.5 million that we had previously accounted for under the equity method. This transaction resulted in the consolidation of the property in our condensed consolidated financial statements, and we recognized a gain of $9.0 million on the fair value remeasurement of our equity method investment. In October 2016, an unconsolidated joint venture distributed land to both us and our partner, and we recognized a gain of $1.9 million associated with the remeasurement of a land parcel. Also, we paid a payable totaling $4.8 million due to the unconsolidated joint venture. In November 2016, we acquired our partner’s interest in two consolidated joint ventures for an aggregate amount of $3.3 million. As of December 31, 2015, we held a combined 51% interest in an unconsolidated real estate joint venture that owned three centers in Colorado with total assets and debt of $43.7 million and $72.4 million, respectively. In February 2016, in exchange for our partners' aggregate 49% interest in this venture and $2.5 million in cash, we distributed one center to our partners. We have consolidated this venture as of the transaction date and re-measured our investment in this venture to its fair value, and recognized a gain of $37.4 million.
