[2] Total assets for the Funds segment include $555.8 million, $569.1 million, and $583.4 million related to Fund II’s City Point property at December 31, 2023, 2022,and 2021, respectively.

[3] At December 31, 2023 and December 31, 2022, totals included VIE assets of $721.2 million and 678.1 million, respectively, and VIE liabilities of $234.7 million and $200.4 million, respectively, related to third-party mortgages that are collateralized by the real estate assets of City Point, a Fund II property, and 27 East 61st Street, 801 Madison Avenue, and 1035 Third Avenue, all Fund IV properties, of which $72.5 million is guaranteed by the Operating Partnership (Note 9). The remaining VIE assets are generally encumbered by third-party non-recourse mortgage debt and are collateral under the respective mortgages and are therefore restricted and can only be used to settle the corresponding liabilities of the VIE. The remaining VIE assets may only be used to settle obligations of these consolidated VIEs and the remaining VIE liabilities are only the obligations of these consolidated VIEs and they do not have recourse to the Operating Partnership or the Company.   Unconsolidated VIEs
