Variable Interest Entities	12. Variable Interest Entities A VIE is an entity that lacks sufficient equity to finance its activities without additional subordinated financial support from other parties, or whose equity holders lack the characteristics of a controlling financial interest. The following discusses the Company's involvement with VIEs where the Company is the primary beneficiary and consolidates the VIEs or where the Company is not the primary beneficiary and does not consolidate the VIEs. Operating Subsidiary The Company's operating subsidiary, OP, is a limited liability company that has governing provisions that are the functional equivalent of a limited partnership. The Company holds the majority of membership interest in OP, acts as the managing member of OP and exercises full responsibility, discretion and control over the day-to-day management of OP. The noncontrolling interests in OP do not have substantive liquidation rights, substantive kick-out rights without cause, or substantive participating rights that could be exercised by a simple majority of noncontrolling interest members (including by such a member unilaterally). The absence of such rights, which represent voting rights in a limited partnership equivalent structure, would render OP to be a VIE. The Company, as managing member, has the power to direct the core activities of OP that most significantly affect OP's performance, and through its majority interest in OP, has both the right to receive benefits from and the obligation to absorb losses of OP. Accordingly, the Company is the primary beneficiary of OP and consolidates OP. As the Company conducts its business and holds its assets and liabilities through OP, the total assets and liabilities, earnings (losses), and cash flows of OP represent substantially all of the total consolidated assets and liabilities, earnings (losses), and cash flows of the Company. Company-Sponsored Private Funds The Company sponsors private funds and other investment vehicles as general partner for the purpose of providing investment management services in exchange for management fees and carried interest. These private funds are established as limited partnerships or equivalent structures. Limited partners of the private funds do not have either substantive liquidation rights, or substantive kick-out rights without cause, or substantive participating rights that could be exercised by a simple majority of limited partners or by a single limited partner. Accordingly, the absence of such rights, which represent voting rights in a limited partnership, results in the private funds being considered VIEs. The nature of the Company's involvement with its sponsored funds comprise fee arrangements and general partner and limited partner equity interests. The fee arrangements are commensurate with the level of management services provided by the Company, and contain terms and conditions that are customary to similar at-market fee arrangements. Consolidated Company-Sponsored Private Funds—The Company currently consolidates sponsored private funds in which it has more than an insignificant equity interest in the fund as general partner. As a result, the Company is considered to be acting in the capacity of a principal of the sponsored private fund and is therefore the primary beneficiary of the fund. The Company’s exposure is limited to the value of its outstanding investment in the consolidated private funds of $94.7 million at December 31, 2022 and $53.1 million at December 31, 2021. The liabilities of the consolidated funds may only be settled using assets of the consolidated funds, and the Company, as general partner, is not obligated to provide any financial support to the consolidated private funds. At December 31, 2022 and December 31, 2021, the consolidated private funds had total assets of $274.2 million and $230.6 million, respectively, and total liabilities of $79.6 million and $63.0 million, respectively, made up primarily of cash, marketable equity securities, unsettled trades, and other equity investment. Unconsolidated Company-Sponsored Private Funds—The Company does not consolidate its sponsored private funds where it has insignificant direct equity interests or capital commitments to these funds as general partner. The Company may invest alongside certain of its sponsored private funds through joint ventures between the Company and these funds, or the Company may have capital commitments to its sponsored private funds that are satisfied directly through the co-investment joint ventures as an affiliate of the general partner. In these instances, the co-investment joint ventures are consolidated by the Company. As the Company's direct equity interests in its sponsored private funds as general partner absorb insignificant variability, the Company is considered to be acting in the capacity of an agent of these funds and is therefore not the primary beneficiary of these funds. The Company accounts for its equity interests in unconsolidated sponsored private funds under the equity method. The Company's maximum exposure to loss is limited to the carrying value of its investment in the unconsolidated sponsored private funds, totaling $748.4 million at December 31, 2022 and $382.7 million at December 31, 2021, included in equity investments, and $1.0 million at December 31, 2022 and $45.4 million at December 31, 2021, included within assets held for disposition. Securitizations The Company previously securitized loans receivable and CRE debt securities using VIEs. Upon securitization, the Company had retained beneficial interests in the securitization vehicles, usually in the form of equity tranches or subordinate securities. The securitization vehicles were structured as pass-through entities that receive principal and interest on the underlying loans or debt securities and distribute those payments to the holders of the notes, certificates or bonds issued by the securitization vehicles. The loans and debt securities were transferred into securitization vehicles such that these assets were restricted and legally isolated from the creditors of the Company, and therefore were not available to satisfy the Company's obligations but only the obligations of the securitization vehicles. The obligations of the securitization vehicles did not have any recourse to the general credit of the Company and its other subsidiaries. The Company also acquired securities issued by securitization trusts that are VIEs. Unconsolidated Securitizations—The Company does not consolidate the assets and liabilities of CLOs or collateralized debt obligations ("CDOs") in which the Company has an interest but does not retain the collateral management function. The Company’s exposure to loss is limited to its investment in these CLOs of $50.9 million at December 31, 2022, or CDOs of $30.2 million at December 31, 2021, previously presented as debt securities within assets held for disposition prior to disposition of the CDOs in February 2022 (Note 21). Trusts Prior to the sale of NRF Holdco in February 2022, wholly-owned subsidiaries of NRF Holdco that were formed as statutory trusts, NorthStar Realty Finance Trust I through VIII (the “Trusts”), previously issued trust preferred securities ("TruPS") in private placement offerings and used the proceeds to purchase junior subordinated notes to evidence loans made to NRF Holdco. The sole assets of the Trusts consisted of a like amount of junior subordinated notes issued by the Issuer at the time of the offerings (the "Junior Notes"). Neither the Company nor the OP was an obligor or guarantor on the Junior Notes or the TruPS. The Company had owned all of the common stock of the Trusts but did not consolidate the Trusts as the holders of the preferred securities issued by the Trusts were the primary beneficiaries of the Trusts. The Company had accounted for its interest in the Trusts under the equity method and its maximum exposure to loss was limited to its investment carrying value of $3.7 million at December 31, 2021. The Trusts were recorded as equity investments and the junior subordinated notes as debt, both previously classified as held for disposition (Note 21)
