[1] On May 25, 2022, the NYC partnership sold the remaining two properties and distributed sales proceeds to the members. Dissolution will follow final distributions, which are expected in 2024.

[2] During April 2022, we acquired our partner's 75% share in four properties held in the RegCal, LLC, partnership for a total purchase price of $88.5 million. Upon acquisition, these four properties were consolidated into Regency's financial statements.

[3] New York Common Retirement Fund (NYC) and RegCal, LLC (RegCal) no longer have any operating properties and any residual balances have been included in Others as of December 31, 2023. The residual balances are primarily made up of the Company’s share of remaining working capital.
