The Condensed Consolidated Balance Sheets include the following amounts related to our consolidated VIEs that are consolidated by the Operating Partnership: $1,828.6 million and $1,640.1 million of Operating real estate, net; $33.2 million and $31.5 million of Real estate under development; $64.4 million and $74.4 million of Investments in and advances to unconsolidated affiliates; $88.6 million and $79.4 million of Other assets, net; $1.8 million and $2.0 million of Right-of-use assets - operating leases, net; $28.2 million and $15.9 million of Cash and cash equivalents; $13.8 million and $11.0 million of Restricted cash; $28.0 million and $27.3 million of Rents receivable, net; $904.5 million and $799.7 million of Mortgage and other notes payable, net; $130.0 million and $120.1 million of Accounts payable and other liabilities; $1.8 million and $2.1 million of Lease liability- operating leases as of June 30, 2025 and December 31, 2024, respectively.
[2] | Total assets for the Investment Management segment include $533.7 million and $549.3 million related to Fund II’s City Point property as of June 30, 2025 and 2024, respectively.
[3] | As of June 30, 2025 and December 31, 2024, total VIE assets of $670.4 million and $705.6 million, respectively, and total VIE liabilities of $235.8 million and $235.1 million, respectively, include third-party mortgage debt 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 serve as collateral under the respective property mortgage loans. These assets are restricted and may only be used to settle the corresponding obligations of the VIEs. Similarly, the remaining VIE liabilities are obligations of these consolidated VIEs and do not have recourse to the Operating Partnership or the Company.
