NOTE 1 — Organization

AIMCO Properties, L.P., a Delaware limited partnership, or the Partnership, was formed on May 16, 1994 to conduct the business of acquiring, redeveloping, leasing, and managing multifamily apartment properties. Our securities include Partnership common units, or common OP Units, Partnership preferred units, or preferred OP Units, and high performance Partnership units, or High Performance Units, which are collectively referred to as “OP Units.” Apartment Investment and Management Company, or Aimco, is the owner of our general partner, AIMCO-GP, Inc., or the General Partner, and special limited partner, AIMCO-LP Trust, or the Special Limited Partner. The General Partner and Special Limited Partner hold common OP Units and are the primary holders of outstanding preferred OP Units. “Limited Partners” refers to individuals or entities that are our limited partners, other than Aimco, the General Partner or the Special Limited Partner, and own common OP Units or preferred OP Units. Generally, after holding the common OP Units for one year, the Limited Partners have the right to redeem their common OP Units for cash, subject to our prior right to acquire some or all of the common OP Units tendered for redemption in exchange for shares of Aimco Class A Common Stock. Common OP Units redeemed for Aimco Class A Common Stock are generally exchanged on a one-for-one basis (subject to antidilution adjustments). Preferred OP Units and High Performance Units may or may not be redeemable based on their respective terms, as provided for in the Fourth Amended and Restated Agreement of Limited Partnership of AIMCO Properties, L.P. as amended, or the Partnership Agreement.

At September 30, 2011, we had outstanding 126,866,035 common OP Units, 27,922,861 preferred OP Units and 2,339,950 High Performance Units. At September 30, 2011, Aimco owned 120,916,144 of the common OP Units and 24,861,411 of the preferred OP Units.

We, through our operating divisions and subsidiaries, hold substantially all of Aimco’s assets and manage the daily operations of Aimco’s business and assets. Aimco is required to contribute all proceeds from offerings of its securities to us. In addition, substantially all of Aimco’s assets must be owned through the Partnership; therefore, Aimco is generally required to contribute all assets acquired to us. In exchange for the contribution of offering proceeds or assets, Aimco receives additional interests in us with similar terms (e.g., if Aimco contributes proceeds of a preferred stock offering, Aimco (through the General Partner and Special Limited Partner) receives preferred OP Units with terms substantially similar to the preferred securities issued by Aimco).

Aimco frequently consummates transactions for our benefit. For legal, tax or other business reasons, Aimco may hold title or ownership of certain assets until they can be transferred to us. However, we have a controlling financial interest in substantially all of Aimco’s assets in the process of transfer to us. Except as the context otherwise requires, “we,” “our” and “us” refer to the Partnership, and the Partnership’s consolidated entities, collectively. Except as the context otherwise requires, “Aimco” refers to Aimco and Aimco’s consolidated entities, collectively.

Our principal financial objective is to provide predictable and attractive returns to our unitholders. Our business plan to achieve this objective is to:

•

own and operate a broadly diversified portfolio of primarily class “B/B+” assets (defined below) with properties concentrated in the 20 largest markets in the United States (as measured by total apartment value, which is the estimated total market value of apartment properties in a particular market);

•

improve our portfolio by selling assets with lower projected returns and reinvesting those proceeds through the purchase of new assets or additional investment in existing assets in our portfolio, including increased ownership or redevelopment; and

•

provide financial leverage primarily by the use of non-recourse, long-dated, fixed-rate property debt and perpetual preferred units.

As of September 30, 2011, we:

•

owned an equity interest in 205 conventional real estate properties with 64,781 units;

	•		owned an equity interest in 201 affordable real estate properties with 24,040 units; and

	•		provided services for, or managed, 11,233 units in 159 properties, primarily pursuant to long-term asset management agreements. In certain cases, we may indirectly own less than one percent of the operations of such properties through a syndication or other fund.

Of these properties, we consolidated 199 conventional properties with 63,335 units and 160 affordable properties with 19,969 units. These conventional and affordable properties generated 87% and 13%, respectively, of our proportionate property net operating income (as defined in Note 11) during the nine months ended September 30, 2011. During the nine months ended September 30, 2011, as part of our ongoing effort to simplify our business, we resigned from our role providing asset or property management services for approximately 100 properties with approximately 11,400 units.

For conventional assets, we focus on the ownership of primarily B/B+ assets. We measure conventional property asset quality based on average rents of our units compared to local market average rents as reported by a third-party provider of commercial real estate performance and analysis, with A-quality assets earning rents greater than 125% of local market average, B-quality assets earning rents 90% to 125% of local market average and C-quality assets earning rents less than 90% of local market average. We classify as B/B+ those assets earning rents ranging from 100% to 125% of local market average. Although some companies and analysts within the multifamily real estate industry use asset class ratings of A, B and C, some of which are tied to local market rent averages, the metrics used to classify asset quality as well as the timing for which local markets rents are calculated may vary from company to company. Accordingly, our rating system for measuring asset quality is neither broadly nor consistently used in the multifamily real estate industry.
