(1)The weighted average leased occupancy for commercial properties represents the total leased square feet divided by the total square footage at acquisition. The weighted average leased occupancy for residential properties represents the total leased units divided by the total available units. Properties under construction are not included in the calculation of weighted average leased occupancy.

(2)As of June 30, 2025, we owned a building at 7 Dey Street / 185 Broadway that was comprised of approximately 140,382 square feet (unaudited) of residential space and approximately 50,206 square feet (unaudited) of office and retail space that is under development. For the purpose of this report, we have included this building in the number of residential properties we own. However, we have included only the residential square footage in the residential approximate square footage, and have listed the balance of the square footage as development square footage.
