| (1) | On August 8, 2019, the Company, through a joint venture in which the Company owned a 90% interest and that it previously consolidated, completed the construction and opened for operation a store located in Waltham, MA. On September 6, 2019, the Company acquired the noncontrolling member’s 10% interest in the venture for $2.6 million. Prior to this transaction, the noncontrolling member’s interest was reported in Noncontrolling interests in subsidiaries on the consolidated balance sheets. Since the Company retained its controlling interest in the joint venture and the store is now wholly owned, this transaction was accounted for as an equity transaction. The carrying amount of the noncontrolling interest was reduced to zero to reflect the purchase and the $2.0 million difference between the purchase price paid by the Company and the carrying amount of the noncontrolling interest was recorded as an adjustment to equity attributable to the Company, with no gain or loss recorded. In conjunction with the Company’s acquisition of the noncontrolling interest, the $10.5 million related party loan extended by the Company to the venture during the construction period was repaid in full.
​
| (2) | These stores were previously owned by two separate consolidated joint ventures, of which the Company held a 51% ownership interest in each. On June 25, 2019, the noncontrolling member in the venture that owned the Bayonne, NJ store put its 49% interest in the venture to the Company for $11.5 million. On September 17, 2019, the noncontrolling member in the venture that owned the Queens, NY store put its 49% interest in the venture to the Company for $15.2 million. These amounts are included in Development costs in the consolidated statements of cash flows.
​
| (3) | This property is subject to a ground lease.
