Sale of partial interest in consolidated real estate joint venture

As of March 31, 2023, our investment in 15 Necco Street, a development project aggregating 345,995 RSF located in our Seaport Innovation District submarket was held in a consolidated real estate joint venture in which 90% was owned by us and 10% was owned by our existing joint venture partner.

In April 2023, an investor acquired a 20% interest in this joint venture, which consists of an 18% interest sold by us and a 2% interest sold by our existing partner. The sales price of the 18% interest sold by us was $66.1 million. Upon completion of the sale, our ownership interest in the consolidated real estate joint venture is 72% and our existing and new partners’ noncontrolling interests are 8% and 20%, respectively. We retained control over this real estate joint venture and therefore continue to consolidate it.

Asset held for sale

In January 2020, we acquired a three-building office campus aggregating 509,702 RSF in our Route 128 submarket. At the time of our acquisition, the campus was fully occupied with a weighted-average remaining lease term of 6.1 years. We had intended to convert the campus into office/laboratory space through redevelopment upon the expirations of the acquired in-place leases.

Since our acquisition, the macroeconomic environment and demand for office space have deteriorated considerably. In April 2023, upon meeting the criteria for classification as held for sale, we recognized a real estate impairment charge of approximately $139 million to reduce our investment in this campus to its current fair value less costs to sell from the book value of $259 million. These buildings represent our only pure operating office campus in the Greater Boston market, and we expect to complete the sale in mid-2023.
