Organization Consolidation And Presentation Of Financial Statements [Abstract]

Note 1 — Organization

Apartment Investment and Management Company (“Aimco”), a Maryland corporation incorporated on January 10, 1994, is a self-administered and self-managed real estate investment trust (“REIT”). Aimco, through a wholly-owned subsidiary, is the general partner and directly is the special limited partner of Aimco OP L.P. (“Aimco Operating Partnership”).

Except as the context otherwise requires, “we,” “our,” and “us” refer to Aimco, Aimco Operating Partnership, and their consolidated subsidiaries, collectively.

The Separation

On December 15, 2020, Aimco completed the separation of its businesses (the “Separation”), creating two, separate and distinct, publicly traded companies, Aimco and Apartment Income REIT Corp. (“AIR”) (Aimco and AIR together, as they existed prior to the Separation, “Aimco Predecessor”).

Prior to the Separation, the consolidated financial statements were prepared on a carve-out basis and reflect significant assumptions and allocations. The consolidated financial statements reflect our historical consolidated financial position, results of operations, and cash flows in conformity with generally accepted accounting principles in the United States (“GAAP”). The historical financial statements of Aimco do not represent the financial position and results of operations of one legal entity, but rather a combination of entities under common control that have been “carved out” from Aimco Predecessor’s financial statements. All significant intercompany balances have been eliminated in consolidation.

All separation related transactions between Aimco and Aimco Predecessor are considered effectively settled through partners’ capital in our consolidated financial statements, other than the Notes Payable to AIR as discussed in Note 7. The settlement of these transactions is reflected as contributions from Aimco Predecessor, net in our consolidated statements of equity and partners’ capital and net change in Aimco Predecessor invesment in financing activity in our consolidated statements of cash flows.

Business

Aimco, through a wholly owned subsidiary, is the general and special limited partner of Aimco Operating Partnership. As of December 31, 2021, Aimco owned 93.1% of the legal interest in the common partnership units of Aimco Operating Partnership and 95.0% of the economic interest in Aimco Operating Partnership. The remaining 6.9% legal interest is owned by limited partners. As the sole general partner of Aimco Operating Partnership, Aimco has exclusive control of Aimco Operating Partnership’s day-to-day management.

We own or lease a portfolio of real estate investments focused primarily on the U.S. multifamily sector. These real estate investments include a portfolio of 29 operating apartment communities (25 consolidated properties with 6,125 apartment homes and four unconsolidated properties), diversified by both geography and price point, in ten major U.S. markets; one commercial office building owned as part of a land assemblage; three residential apartment communities, with 1,331 planned apartment homes, a single family rental community, with 16 planned homes plus eight accessory dwelling units, and one hotel, with 106 planned rooms, that we are actively developing or redeveloping; land parcels held for development; and three residential apartment communities with 499 apartment homes, for which we have completed the redevelopment and are in lease-up, but have not achieved stabilization.
