FORWARD-LOOKING STATEMENTS

The Private Securities Litigation Reform Act of 1995 provides a “safe harbor” for forward-looking statements in certain circumstances. Certain information included in this Annual Report contains or may contain information that is forward-looking within the meaning of the federal securities laws, including, without limitation, statements regarding the effect of acquisitions and redevelopments, our future financial performance, including our ability to maintain current or meet projected occupancy, rent levels and same store results, and the effect of government regulations. Actual results may differ materially from those described in these forward-looking statements and, in addition, will be affected by a variety of risks and factors, some of which are beyond our control, including, without limitation: financing risks, including the availability and cost of financing and the risk that our cash flows from operations may be insufficient to meet required payments of principal and interest; earnings may not be sufficient to maintain compliance with debt covenants; real estate risks, including fluctuations in real estate values and the general economic climate in the markets in which we operate and competition for residents in such markets; national and local economic conditions; the terms of governmental regulations that affect us and interpretations of those regulations; the competitive environment in which we operate; the timing of acquisitions and dispositions; insurance risk, including the cost of insurance; natural disasters and severe weather such as hurricanes; litigation, including costs associated with prosecuting or defending claims and any adverse outcomes; energy costs; and possible environmental liabilities, including costs, fines or penalties that may be incurred due to necessary remediation of contamination of properties presently owned or previously owned by us. In addition, Aimco’s current and continuing qualification as a real estate investment trust involves the application of highly technical and complex provisions of the Internal Revenue Code and depends on our ability to meet the various requirements imposed by the Internal Revenue Code, through actual operating results, distribution levels and diversity of stock ownership. Readers should carefully review our financial statements and the notes thereto, as well as the section entitled “Risk Factors” described in Item 1A of this Annual Report and the other documents we file from time to time with the Securities and Exchange Commission.

PART I

Item 1.		Business

The Partnership

AIMCO Properties, L.P., a Delaware limited partnership, or the Partnership, and together with its consolidated subsidiaries, was formed on May 16, 1994, to engage in the acquisition, ownership, management and redevelopment of 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.

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 stock 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.

We own an equity interest in, and consolidate the majority of, the properties in our owned real estate portfolio. These properties represent the consolidated real estate holdings in our financial statements, which we refer to as consolidated properties. In addition, we have an equity interest in, but do not consolidate for financial statement purposes, certain properties that are accounted for under the equity or cost methods. These properties represent our investment in unconsolidated real estate partnerships in our financial statements, which we refer to as unconsolidated properties. Additionally, we provide property management and asset management services to certain properties, and in certain cases, we may indirectly own generally less than one percent of the operations of such properties through a partnership syndication or other fund. Our equity holdings and managed properties are as follows as of December 31, 2009:

		Total Portfolio
		Properties				Units
Consolidated properties			426				95,202
Unconsolidated properties			77				8,478
Property management			22				2,095
Asset management			345				29,879
Total			870				135,654

At December 31, 2009, we had outstanding 122,509,304 common OP Units, 28,096,618 preferred OP Units and 2,344,719 High Performance Units (see Note 11 to the consolidated financial statements in Item 8). At December 31, 2009, Aimco owned 116,479,791 of the common OP Units and 24,940,134 of the preferred OP Units.

Since Aimco’s initial public offering in July 1994, we have completed numerous transactions, including purchases of properties and interests in entities that own or manage properties, expanding our portfolio of owned or managed properties from 132 properties with 29,343 apartment units to a peak of over 2,100 properties with 379,000 apartment units. As of December 31, 2009, our portfolio of owned and/or managed properties consists of 870 properties with 135,654 apartment units.

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. As used herein, and except where the context otherwise requires, “partnership” refers to a limited partnership or a limited liability company and “partner” refers to a limited partner in a limited partnership or a member in a limited liability company.

Available Information

We do not maintain a website; however, Aimco does, and it makes all of its filings with the Securities and Exchange Commission, or SEC, available free of charge as soon as reasonably practicable through its website at www.aimco.com. The information contained on Aimco’s website is not incorporated into this Annual Report. We will furnish copies of the Partnership’s filings free of charge upon written request to Aimco’s corporate secretary.

Any materials we file with the SEC may be read and copied at the SEC’s Public Reference Room at 100 F Street, NE., Washington, DC 20549. Information on the operation of the Public Reference Room may be obtained by calling the SEC at 1-800-SEC-0330. The SEC maintains an Internet site (http://www.sec.gov) that contains reports, proxy and information statements, and other information regarding issuers that file electronically with the SEC.

Financial Information About Industry Segments

We operate in two reportable segments: real estate (owning, operating and redeveloping apartments) and investment management (portfolio management and asset management, which are further discussed in the Business Overview). For further information on these segments, see Note 17 of the consolidated financial statements in Item 8, and Management’s Discussion and Analysis in Item 7.

Business Overview

Our principal financial objective is to increase long-term OP unitholder value, both as measured by Net Asset Value, which is the estimated fair value of our assets, net of debt, or NAV, and total unitholder return.

We strive to meet our objectives through:

	•		property operations — using scale and technology to increase the effectiveness and efficiency of attracting and retaining apartment residents;
	•		portfolio management — allocating capital among geographic markets and apartment property types, primarily Class B and B+ quality apartments that are well located within the 20 largest U.S. markets, through sales, redevelopment and/or acquisitions;
	•		managing our cost and risk of capital by using leverage that is largely long-term, laddered in maturity, non-recourse and property specific; and
	•		reducing our general and administrative and certain other costs through outsourcing and standardization.

Our business is organized around two core activities: Property Operations and Investment Management. These core activities, along with our financial strategy, are described in more detail below.

Property Operations

Our portfolio is comprised of two business components: conventional and affordable. Our conventional operations, which provide 88% of our property net operating income and are market-rate apartments with rents paid by the resident, include 243 properties with 74,030 units. Our affordable operations provide 12% of our property net operating income and consist of 260 properties with 29,650 units, with rents that are generally paid, in whole or part, by a government agency. Affordable properties tend to have relatively more stable rents and higher occupancy due to government rent payments and thus are much less affected by market fluctuations.

We operate a broad range of property types, from suburban garden-style to urban high-rise properties in 44 states, the District of Columbia and Puerto Rico at a range of average monthly rental rates. On average, our portfolio rents are somewhat above the average rents in the local markets. This diversification in geography insulates us, to some degree, from inevitable downturns in any one market.

Our property operations currently are organized into five areas, which are further subdivided according to our target markets. To manage our nationwide portfolio more efficiently and to increase the benefits from our local management expertise, we have given direct responsibility for operations within each area to an area operations leader with regular senior management reviews. To enable the area operations leaders to focus on sales and service, as well as to improve financial control and budgeting, we have dedicated an area financial officer to support each area operations leader, and with the exception of routine maintenance, our specialized Construction Services group manages all on-site improvements, thus reducing the need for the area operations leaders to spend time on oversight of construction projects.

We seek to improve our oversight of property operations by: developing better systems; standardizing business goals, operational measurements and internal reporting; and enhancing financial controls over field operations. Our objectives are to focus on the areas discussed below:

	•		Customer Service. Our operating culture is focused on our residents. Our goal is to provide our residents with consistent service in clean, safe and attractive communities. We evaluate our performance through a customer satisfaction tracking system. In addition, we emphasize the quality of our on-site employees through recruiting, training and retention programs, which we believe contributes to improved customer service and leads to increased occupancy rates and enhanced operational performance.
	•		Resident Selection and Retention. In apartment properties, neighbors are a meaningful part of the product, together with the location of the property and the physical quality of the apartment units. Part of our property operations strategy is to focus on resident acquisition and retention — attracting and retaining credit-worthy residents who are good neighbors. We have structured goals and coaching for all of our sales personnel, a tracking system for inquiries and a standardized renewal communication program. We have standardized residential financial stability requirements and have policies and monitoring practices to maintain our resident quality.
	•		Revenue Management. For our conventional properties, we have a centralized revenue management system that leverages people, processes and technology to work in partnership with our area operational management teams to develop rental rate pricing. We seek to increase revenue by optimizing the balance between rental and occupancy rates. We are also focused on the automation of on-site operations, as we believe that timely and accurate collection of property performance and resident profile data will enable us to maximize revenue through better property management and leasing decisions. We have standardized policies for new and renewal pricing with timely data and analyses by floor-plan, thereby enabling us to maximize our ability to modify pricing, even in challenging sub-markets.

	•		Controlling Expenses. Cost controls are accomplished by local focus at the area level and by taking advantage of economies of scale at the corporate level. As a result of the size of our portfolio and our area concentrations of properties, we have the ability to spread over a large property base the fixed costs for general and administrative expenditures and certain operating functions, such as purchasing, insurance and information technology.
	•		Ancillary Services. We believe that our ownership and management of properties provide us with unique access to a customer base that allows us to provide additional services and thereby increase occupancy and rents, while also generating incremental revenue. We currently provide cable television, telephone services, appliance rental, and carport, garage and storage space rental at certain properties.
	•		Maintaining and Improving Property Quality. We believe that the physical condition and amenities of our apartment properties are important factors in our ability to maintain and increase rental rates. In 2009, we spent $70.3 million (our share), or $723 per owned apartment unit, for Capital Replacements, which represent the share of additions that are deemed to replace the consumed portion of acquired capital assets. Additionally, we spent $53.4 million (our share), or $549 per owned apartment unit, for Capital Improvements, which are non-redevelopment capital additions that are made to enhance the value, profitability or useful life of an asset from its original purchase condition.

Investment Management

Investment management includes activities related to our owned portfolio of properties as well as services provided to affiliated partnerships. Investment management includes portfolio strategy, capital allocation, joint ventures, tax credit syndication, acquisitions, dispositions and other transaction activities. Within our owned portfolio, we refer to these activities as Portfolio Management, and their benefit is seen in property operating results and investment gains. For affiliated partnerships, we refer to these activities as asset management for which we are separately compensated through fees paid by third party investors.

Portfolio Management

Portfolio Management involves the ongoing allocation of investment capital to meet our geographic and product type goals. We target geographic balance in our diversified portfolio in order to optimize risk-adjusted returns and to avoid the risk of undue concentration in any particular market. We also seek to balance the portfolio by product type, with both high quality properties in excellent locations and also high land value properties that support redevelopment activities. We intend to slightly reduce our allocation of capital to affordable properties to 10% of our NAV.

Our geographic allocation strategy focuses on our target markets to reduce volatility in and our dependence on particular areas of the country. We believe our target markets are deep, relatively liquid and possess desirable long-term growth characteristics. They are primarily coastal markets, and also include a number of Sun Belt cities and Chicago, Illinois. We may also invest in other markets on an opportunistic basis. We intend to upgrade the quality of our portfolio through the sale of approximately 5% to 10% of our portfolio annually, with the proceeds generally used to increase our allocation of capital to well located properties within our target markets through capital investments, redevelopment or acquisitions. We expect that increased geographic focus will also add to our investment knowledge and increase operating efficiencies based on local economies of scale.

Our portfolio management activities include strategic portfolio and capital allocation decisions including transactions to buy, sell or modify our ownership interest in properties, including through the use of partnerships and joint ventures, and to increase our investment in existing properties through redevelopment. The purpose of these transactions is to adjust our investments to reflect our decisions regarding target allocations to geographic markets and to investment types.

We believe redevelopment of certain properties in superior locations provides advantages over ground-up development, enabling us to generate rents comparable to new properties with lower financial risk, in less time and with reduced delays associated with governmental permits and authorizations. Redevelopment work also includes seeking entitlements from local governments, which enhance the value of our existing portfolio by increasing density, that is, the right to add residential units to a site. We have historically undertaken a range of redevelopment projects: from those in which a substantial number of all available units are vacated for significant renovations to the property, to those in which there is significant renovation, such as exteriors, common areas or unit improvements, typically done upon lease expirations without the need to vacate units on any wholesale or substantial basis. We have a specialized Redevelopment and Construction Services group to oversee these projects.

During 2009, we increased our allocation of capital to our target markets by disposing of 68 conventional properties located primarily outside of our target markets or in less desirable locations within our target markets and by investing $66.8 million in redevelopment of conventional properties. As of December 31, 2009, our conventional portfolio included 243 properties with 74,030 units in 38 markets. As of December 31, 2009, conventional properties in our target markets comprised 88% of our NAV attributable to our conventional properties. Our top five markets by net operating income contribution include the metropolitan areas of Washington, D.C.; Los Angeles, California; “Other” Florida (which is comprised of Ft. Lauderdale, Jacksonville, Orlando, Palm Beach County and Tampa); Chicago, Illinois and Boston, Massachusetts.

During 2009, we invested $46.0 million in redevelopment of affordable properties, funded primarily by proceeds from the sale of tax credits to institutional partners. As with conventional properties, we also seek to dispose of properties that are inconsistent with our long-term investment and operating strategies. During 2009, we sold 22 properties from our affordable portfolio. As of December 31, 2009, our affordable portfolio included 260 properties with 29,650 units.

Financial Strategy

We are focused on maintaining a safe balance sheet, including minimizing or eliminating our recourse debt and near term property debt maturities as well as minimizing our cost of capital on a risk adjusted basis. We primarily use non-recourse and amortizing property debt with laddered maturities and minimize reliance on corporate debt. The lower risk inherent in non-recourse property debt permits us to operate with higher debt leverage and a lower weighted average cost of capital. We use floating rate property and corporate debt to provide lower interest costs over time at a level that considers acceptable earnings volatility.

During 2009, using proceeds from asset dispositions, we repaid $310.0 million of our term loan, which matures in March 2011, leaving a remaining outstanding balance of $90.0 million at December 31, 2009. We repaid an additional $45.0 million through February 26, 2010, leaving a remaining outstanding balance of $45.0 million.

During 2009, we also focused on reducing refunding risk by accelerating refinancing of property loans maturing prior to 2012. At the beginning of 2009, property debt totaling $753.0 million was scheduled to mature prior to 2012. During 2009, through refinancing, repayment and property sales, we reduced these maturities by 69%, or $516.3 million, and eliminated all 2010 property debt maturities. As of December 31, 2009, five loans totaling $236.7 million were scheduled to mature in 2011. During January 2010, we extended the maturity of one of these loans for $65.0 million to 2013. We expect to refinance the remaining four loans, totaling $171.7 million ($101.2 million our share), at their maturity.

As of December 31, 2009, we had a $180.0 million revolving credit facility and borrowings available of $136.2 million (after giving effect to $43.8 million outstanding for undrawn letters of credit). The revolving credit facility matures in May 2011 and has a one year extension option, subject to certain terms.

Competition

In attracting and retaining residents to occupy our properties we compete with numerous other housing alternatives. Our properties compete directly with other rental apartments as well as condominiums and single-family homes that are available for rent or purchase in the markets in which our properties are located. Principal factors of competition include rent or price charged, attractiveness of the location and property and quality and breadth of services. The number of competitive properties relative to demand in a particular area has a material effect on our ability to lease apartment units at our properties and on the rents we charge. In certain markets there exists oversupply of single family homes and condominiums and a reduction of households, both of which affect the pricing and occupancy of our rental apartments. Additionally, we compete with other real estate investors, including other apartment REITs, pension and investment funds, partnerships and investment companies in acquiring, redeveloping and managing apartment properties. This competition affects our ability to acquire properties we want to add to our portfolio and the price that we pay in such acquisitions.

Taxation

We are treated as a “pass-through” entity for United States Federal income tax purposes and are not subject to United States Federal income taxation. Each of our partners, however, is subject to tax on his allocable share of partnership tax items, including partnership income, gains, losses, deductions and credits, or Partnership Tax Items, for each taxable year during which he is a partner, regardless of whether he receives any actual distributions of cash or other property from us during the taxable year. Generally, the characterization of any particular Partnership Tax Item is determined by us, rather than at the partner level, and the amount of a partner’s allocable share of such item is governed by the terms of the Partnership Agreement. The General Partner is our “tax matters partner” for United States Federal income tax purposes. The tax matters partner is authorized, but not required, to take certain actions on behalf of us with respect to tax matters.

Regulation

General

Apartment properties and their owners are subject to various laws, ordinances and regulations, including those related to real estate broker licensing and regulations relating to recreational facilities such as swimming pools, activity centers and other common areas. Changes in laws increasing the potential liability for environmental conditions existing on properties or increasing the restrictions on discharges or other conditions, as well as changes in laws affecting development, construction and safety requirements, may result in significant unanticipated expenditures, which would adversely affect our net income and cash flows from operating activities. In addition, future enactment of rent control or rent stabilization laws, such as legislation that has been considered in New York, or other laws regulating multifamily housing may reduce rental revenue or increase operating costs in particular markets.

Environmental

Various Federal, state and local laws subject property owners or operators to liability for management, and the costs of removal or remediation, of certain hazardous substances present on a property. Such laws often impose liability without regard to whether the owner or operator knew of, or was responsible for, the release or presence of the hazardous substances. In connection with the ownership, operation and management of properties, we could potentially be liable for environmental liabilities or costs associated with our properties or properties we acquire or manage in the future. These and other risks related to environmental matters are described in more detail in Item 1A, “Risk Factors.”

Insurance

Our primary lines of insurance coverage are property, general liability, and workers’ compensation. We believe that our insurance coverages adequately insure our properties against the risk of loss attributable to fire, earthquake, hurricane, tornado, flood, terrorism and other perils, and adequately insure us against other risk. Our coverage includes deductibles, retentions and limits that are customary in the industry. We have established loss prevention, loss mitigation, claims handling, litigation management and loss reserving procedures to manage our exposure.

Employees

At December 31, 2009, we had approximately 3,500 employees, of which approximately 2,800 were at the property level, performing various on-site functions, with the balance managing corporate and area operations, including investment and debt transactions, legal, financial reporting, accounting, information systems, human resources and other support functions. As of December 31, 2009, unions represented 115 of our employees. We have never experienced a work stoppage and believe we maintain satisfactory relations with our employees.

Item 1A.		Risk Factors

The risk factors noted in this section and other factors noted throughout this Annual Report, describe certain risks and uncertainties that could cause our actual results to differ materially from those contained in any forward-looking statement.

Our existing and future debt financing could render us unable to operate, result in foreclosure on our properties, prevent us from making distributions on our equity or otherwise adversely affect our liquidity.

We are subject to the risk that our cash flow from operations will be insufficient to make required payments of principal and interest, and the risk that existing indebtedness may not be refinanced or that the terms of any refinancing will not be as favorable as the terms of existing indebtedness. If we fail to make required payments of principal and interest on secured debt, our lenders could foreclose on the properties and other collateral securing such debt, which would result in loss of income and asset value to us. As of December 31, 2009, substantially all of the properties that we owned or controlled were encumbered by debt. Our organizational documents do not limit the amount of debt that we may incur, and we have significant amounts of debt outstanding. Payments of principal and interest may leave us with insufficient cash resources to operate our properties or pay distributions required to be paid in order to maintain Aimco’s qualification as a REIT.

Our strategy is generally to incur debt to increase the return on our capital while maintaining acceptable coverage ratios. For the year ended December 31, 2009, as calculated based on the provisions in our credit agreement, which is further discussed in Note 7 to the consolidated financial statements in Item 8, we had a ratio of earnings before interest, taxes and depreciation and amortization to debt service of 1.59:1 and a ratio of earnings to fixed charges of 1.36:1. On February 3, 2010, we and our lenders agreed to reduce the covenant ratios of earnings before interest, taxes and depreciation and amortization to debt service and earnings to fixed charges from 1.50:1 and 1.30:1, respectively, to 1.40:1 and 1.20:1, respectively. We expect to remain in compliance with these covenants.

At December 31, 2009, we had swap positions with two financial institutions totaling $353.1 million. The related swap agreements provide for collateral calls to maintain specified loan-to-value ratios. In the event the values of the real estate properties serving as collateral under these agreements decline, we may be required to provide additional collateral pursuant to the swap agreements, which would adversely affect our cash flows.

Disruptions in the financial markets could affect our ability to obtain financing and the cost of available financing and could adversely affect our liquidity.

Our ability to obtain financing and the cost of such financing depends on the overall condition of the United States credit markets and, to an important extent in 2009, on the level of involvement of certain government sponsored entities, specifically, Federal Home Loan Mortgage Corporation, or Freddie Mac, and Federal National Mortgage Association, or Fannie Mae, in secondary credit markets. During 2009, the United States credit markets (outside of multi-family) experienced significant liquidity disruptions, which caused the spreads on debt financings to widen considerably and made obtaining financing, both non-recourse property debt and corporate borrowings, such as our term loan or revolving credit facility, more difficult.

Further or prolonged disruptions in the credit markets could result in Freddie Mac or Fannie Mae reducing their level of involvement in secondary credit markets, which would adversely affect our ability to obtain non-recourse property debt financing. Additionally, further or prolonged disruptions in the credit markets may also affect our ability to renew our credit facility with similar commitments when it matures in May 2012 (inclusive of a one year extension option).

If our ability to obtain financing is adversely affected, we may be unable to satisfy scheduled maturities on existing financing through other sources of liquidity, which could result in lender foreclosure on the properties securing such debt and loss of income and asset value, each of which would adversely affect our liquidity.

Increases in interest rates would increase our interest expense and reduce our profitability.

As of December 31, 2009, we had approximately $654.6 million of variable-rate indebtedness outstanding and $67.0 million of variable rate preferred OP Units outstanding. Of the total debt subject to variable interest rates, floating rate tax-exempt bond financing was about two-thirds, or $433.9 million. Floating rate tax-exempt bond financing is benchmarked against the Securities Industry and Financial Markets Association Municipal Swap Index, or SIFMA, rate, which since 1989 has averaged 73% of the 30-day LIBOR rate. At December 31, 2009, we had approximately $440.9 million in cash and cash equivalents, restricted cash and notes receivable, the majority of which bear interest. The effect of our interest-bearing assets would partially reduce the effect of an increase in variable interest rates. If this historical relationship continues, we estimate that an increase in 30-day LIBOR of 100 basis points (73 basis points for tax-exempt interest rates) with constant credit risk spreads would result in net income being reduced by $1.1 million and income attributable to the Partnership’s common unitholders being reduced by $1.6 million on an annual basis.

Failure to generate sufficient net operating income may adversely affect our liquidity, limit our ability to fund necessary capital expenditures or adversely affect our ability to pay distributions.

Our ability to fund necessary capital expenditures on our properties depends on, among other things, our ability to generate net operating income in excess of required debt payments. If we are unable to fund capital expenditures on our properties, we may not be able to preserve the competitiveness of our properties, which could adversely affect our net operating income.

Our ability to make payments to our investors depends on our ability to generate net operating income in excess of required debt payments and capital expenditure requirements. Our net operating income and liquidity may be adversely affected by events or conditions beyond our control, including:

	•		the general economic climate;
	•		an inflationary environment in which the costs to operate and maintain our properties increase at a rate greater than our ability to increase rents only upon renewal of existing leases or at the inception of new leases;
	•		competition from other apartment communities and other housing options;
	•		local conditions, such as loss of jobs, unemployment rates or an increase in the supply of apartments, that might adversely affect apartment occupancy or rental rates;
	•		changes in governmental regulations and the related cost of compliance;
	•		increases in operating costs (including real estate taxes) due to inflation and other factors, which may not be offset by increased rents;
	•		changes in tax laws and housing laws, including the enactment of rent control laws or other laws regulating multifamily housing; and
	•		changes in interest rates and the availability of financing.

Increases in inflation or jobless rates could adversely affect our results of operations and liquidity.

In an inflationary environment, the costs to operate and maintain our properties may increase, although we may increase rents upon renewal of existing leases or at the inception of new leases. However, if we are unable to increase rents at levels commensurate with the increases in operating costs, our results of operations and liquidity would be adversely affected. If unemployment rates rise or remain at elevated levels, we may not be able to raise rental rates at our properties, which, coupled with inflationary pressures discussed above, could adversely affect our results of operations and liquidity.

Covenant restrictions may limit our ability to make payments to our investors.

Some of our debt and other securities contain covenants that restrict our ability to make distributions or other payments to our investors unless certain financial tests or other criteria are satisfied. Our credit facility provides, among other things, that we may make distributions to our investors during any four consecutive fiscal quarters in an aggregate amount that does not exceed the greater of 95% of our Funds From Operations for such period, subject to certain non-cash adjustments, or such amount as may be necessary to maintain Aimco’s REIT status. Our outstanding classes of preferred OP Units prohibit the payment of distributions on our common OP Units if we fail to pay the distributions to which the holders of the preferred OP Units are entitled.

Because real estate investments are relatively illiquid, we may not be able to sell properties when appropriate.

Real estate investments are relatively illiquid and cannot always be sold quickly. Our freedom to sell properties is also restricted by REIT tax rules applicable to Aimco. Thus, we may not be able to change our portfolio promptly in response to changes in economic or other market conditions. Our ability to dispose of assets in the future will depend on prevailing economic and market conditions, including the cost and availability of financing. This could have a material adverse effect on our financial condition or results of operations.

Competition could limit our ability to lease apartments or increase or maintain rents.

Our apartment properties compete for residents with other housing alternatives, including other rental apartments, condominiums and single-family homes that are available for rent, as well as new and existing condominiums and single-family homes for sale. Competitive residential housing in a particular area could adversely affect our ability to lease apartments and to increase or maintain rental rates. The current challenges in the credit and housing markets have increased housing inventory that competes with our apartment properties.

Our subsidiaries may be prohibited from making distributions and other payments to us.

All of our properties are owned, and all of our operations are conducted, by us and our subsidiaries. As a result, we depend on distributions and other payments from our subsidiaries in order to satisfy our financial obligations and make payments to our investors. The ability of our subsidiaries to make such distributions and other payments depends on their earnings and cash flows and may be subject to statutory or contractual limitations. As an equity investor in our subsidiaries, our right to receive assets upon their liquidation or reorganization will be effectively subordinated to the claims of their creditors. To the extent that we are recognized as a creditor of such subsidiaries, our claims may still be subordinate to any security interest in or other lien on their assets and to any of their debt or other obligations that are senior to our claims.

Redevelopment and construction risks could affect our profitability.

We intend to continue to redevelop certain of our properties. These activities are subject to the following risks:

	•		we may be unable to obtain, or experience delays in obtaining, necessary zoning, occupancy, or other required governmental or third party permits and authorizations, which could result in increased costs or the delay or abandonment of opportunities;
	•		we may incur costs that exceed our original estimates due to increased material, labor or other costs such as litigation;
	•		we may be unable to complete construction and lease up of a property on schedule, resulting in increased construction and financing costs and a decrease in expected rental revenues;
	•		occupancy rates and rents at a property may fail to meet our expectations for a number of reasons, including changes in market and economic conditions beyond our control and the development by competitors of competing communities;
	•		we may be unable to obtain financing with favorable terms, or at all, for the proposed development of a property, which may cause us to delay or abandon an opportunity;
	•		we may abandon opportunities that we have already begun to explore for a number of reasons, including changes in local market conditions or increases in construction or financing costs, and, as a result, we may fail to recover expenses already incurred in exploring those opportunities;
	•		we may incur liabilities to third parties during the redevelopment process, for example, in connection with resident lease terminations, or managing existing improvements on the site prior to resident lease terminations; and
	•		loss of a key member of a project team could adversely affect our ability to deliver redevelopment projects on time and within our budget.

We are insured for certain risks, and the cost of insurance, increased claims activity or losses resulting from casualty events may affect our operating results and financial condition.

We are insured for a portion of our consolidated properties’ exposure to casualty losses resulting from fire, earthquake, hurricane, tornado, flood and other perils, which insurance is subject to deductibles and self-insurance retention. We recognize casualty losses or gains based on the net book value of the affected property and any related insurance proceeds. In many instances, the actual cost to repair or replace the property may exceed its net book value and the amount of any insurance proceeds. We also insure certain unconsolidated properties for a portion of their exposure to such losses. With respect to our consolidated properties, we recognize the uninsured portion of losses as part of casualty losses in the periods in which they are incurred. In addition, we are self-insured for a portion of our exposure to third-party claims related to our employee health insurance plans, workers’ compensation coverage and general liability exposure. With respect to our insurance obligations to unconsolidated properties and our exposure to claims of third parties, we establish reserves at levels that reflect our known and estimated losses. The ultimate cost of losses and the impact of unforeseen events may vary materially from recorded reserves, and variances may adversely affect our operating results and financial condition. We purchase insurance (or reinsurance where we insure unconsolidated properties) to reduce our exposure to losses and limit our financial losses on large individual risks. The availability and cost of insurance are determined by market conditions outside our control. No assurance can be made that we will be able to obtain and maintain insurance at the same levels and on the same terms as we do today. If we are not able to obtain or maintain insurance in amounts we consider appropriate for our business, or if the cost of obtaining such insurance increases materially, we may have to retain a larger portion of the potential loss associated with our exposures to risks.

Natural disasters and severe weather may affect our operating results and financial condition.

Natural disasters and severe weather such as hurricanes may result in significant damage to our properties. The extent of our casualty losses and loss in operating income in connection with such events is a function of the severity of the event and the total amount of exposure in the affected area. When we have geographic concentration of exposures, a single catastrophe (such as an earthquake) or destructive weather event (such as a hurricane) affecting a region may have a significant negative effect on our financial condition and results of operations. We cannot accurately predict natural disasters or severe weather, or the number and type of such events that will affect us. As a result, our operating and financial results may vary significantly from one period to the next. Although we anticipate and plan for losses, there can be no assurance that our financial results will not be adversely affected by our exposure to losses arising from natural disasters or severe weather in the future that exceed our previous experience and assumptions.

We depend on our senior management.

Our success depends upon the retention of our senior management, including Terry Considine, Aimco’s chief executive officer. We have a succession planning and talent development process that is designed to identify potential replacements and develop our team members to provide depth in the organization and a bench of talent on which to draw. However, there are no assurances that we would be able to find qualified replacements for the individuals who make up our senior management if their services were no longer available. The loss of services of one or more members of our senior management team could have a material adverse effect on our business, financial condition and results of operations. We do not currently maintain key-man life insurance for any of our employees.

If we are not successful in our acquisition of properties, our results of operations could be adversely affected.

The selective acquisition of properties is a component of our strategy. However, we may not be able to complete transactions successfully in the future. Although we seek to acquire properties when such acquisitions increase our net income, Funds From Operations or net asset value, such transactions may fail to perform in accordance with our expectations. In particular, following acquisition, the value and operational performance of a property may be diminished if obsolescence or neighborhood changes occur before we are able to redevelop or sell the property.

We may be subject to litigation associated with partnership transactions that could increase our expenses and prevent completion of beneficial transactions.

We have engaged in, and intend to continue to engage in, the selective acquisition of interests in partnerships controlled by us that own apartment properties. In some cases, we have acquired the general partner of a partnership and then made an offer to acquire the limited partners’ interests in the partnership. In these transactions, we may be subject to litigation based on claims that we, as the general partner, have breached our fiduciary duty to our limited partners or that the transaction violates the relevant partnership agreement or state law. Although we intend to comply with our fiduciary obligations and the relevant partnership agreements, we may incur additional costs in connection with the defense or settlement of this type of litigation. In some cases, this type of litigation may adversely affect our desire to proceed with, or our ability to complete, a particular transaction. Any litigation of this type could also have a material adverse effect on our financial condition or results of operations.

Government housing regulations may limit the opportunities at some of our properties and failure to comply with resident qualification requirements may result in financial penalties and/or loss of benefits, such as rental revenues paid by government agencies.

We own consolidated and unconsolidated equity interests in certain properties and manage other properties that benefit from governmental programs intended to provide housing to people with low or moderate incomes. These programs, which are usually administered by the U.S. Department of Housing and Urban Development, or HUD, or state housing finance agencies, typically provide mortgage insurance, favorable financing terms, tax-credit equity, or rental assistance payments to the property owners. As a condition of the receipt of assistance under these programs, the properties must comply with various requirements, which typically limit rents to pre-approved amounts and impose restrictions on resident incomes. Failure to comply with these requirements and restrictions may result in financial penalties or loss of benefits. We usually need to obtain the approval of HUD in order to acquire or dispose of a significant interest in or manage a HUD-assisted property. We may not always receive such approval.

During 2009, 2008 and 2007, for continuing operations, our rental revenues include $140.3 million, $132.3 million and $121.4 million, respectively, of subsidies from government agencies. Any loss of such benefits would adversely affect our liquidity and results of operations.

Laws benefiting disabled persons may result in our incurrence of unanticipated expenses.

Under the Americans with Disabilities Act of 1990, or ADA, all places intended to be used by the public are required to meet certain Federal requirements related to access and use by disabled persons. Likewise, the Fair Housing Amendments Act of 1988, or FHAA, requires apartment properties first occupied after March 13, 1990, to be accessible to the handicapped. These and other Federal, state and local laws may require modifications to our properties, or affect renovations of the properties. Noncompliance with these laws could result in the imposition of fines or an award of damages to private litigants and also could result in an order to correct any non-complying feature, which could result in substantial capital expenditures. Although we believe that our properties are substantially in compliance with present requirements, we may incur unanticipated expenses to comply with the ADA and the FHAA in connection with the ongoing operation or redevelopment of our properties.

Potential liability or other expenditures associated with potential environmental contamination may be costly.

Various Federal, state and local laws subject property owners or operators to liability for management, and the costs of removal or remediation, of certain hazardous substances present on a property, including lead-based paint. Such laws often impose liability without regard to whether the owner or operator knew of, or was responsible for, the release or presence of the hazardous substances. The presence of, or the failure to manage or remedy properly, hazardous substances may adversely affect occupancy at affected apartment communities and the ability to sell or finance affected properties. In addition to the costs associated with investigation and remediation actions brought by government agencies, and potential fines or penalties imposed by such agencies in connection therewith, the presence of hazardous substances on a property could result in claims by private plaintiffs for personal injury, disease, disability or other infirmities. Various laws also impose liability for the cost of removal, remediation or disposal of hazardous substances through a licensed disposal or treatment facility. Anyone who arranges for the disposal or treatment of hazardous substances is potentially liable under such laws. These laws often impose liability whether or not the person arranging for the disposal ever owned or operated the disposal facility. In connection with the ownership, operation and management of properties, we could potentially be liable for environmental liabilities or costs associated with our properties or properties we acquire or manage in the future.

Moisture infiltration and resulting mold remediation may be costly.

We have been named as a defendant in lawsuits that have alleged personal injury and property damage as a result of the presence of mold. In addition, we are aware of lawsuits against owners and managers of multifamily properties asserting claims of personal injury and property damage caused by the presence of mold, some of which have resulted in substantial monetary judgments or settlements. We have only limited insurance coverage for property damage loss claims arising from the presence of mold and for personal injury claims related to mold exposure. We have implemented policies, procedures, third-party audits and training, and include a detailed moisture intrusion and mold assessment during acquisition due diligence. We believe these measures will prevent or eliminate mold exposure from our properties and will minimize the effects that mold may have on our residents. To date, we have not incurred any material costs or liabilities relating to claims of mold exposure or to abate mold conditions. Because the law regarding mold is unsettled and subject to change, we can make no assurance that liabilities resulting from the presence of or exposure to mold will not have a material adverse effect on our consolidated financial condition or results of operations.

Aimco’s failure to qualify as a REIT would place us in default under our primary credit facilities.

Aimco believes it operates, and has always operated, in a manner that enables it to meet the requirements for qualification as a REIT for Federal income tax purposes. However, Aimco’s current and continuing qualification as a REIT depends on its ability to meet the various requirements imposed by the Code, which are related to organizational structure, distribution levels, diversity of stock ownership and certain restrictions with regard to owned assets and categories of income. These requirements are complex and accordingly there can be no assurances that the Internal Revenue Service will not contend that Aimco has violated provisions of the Code and fails to qualify as a REIT. If Aimco fails to qualify as a REIT, we would then be in default under our primary credit facilities.

REIT distribution requirements limit our available cash.

As a REIT, Aimco is subject to annual distribution requirements. As Aimco’s operating partnership, we pay distributions intended to enable Aimco to satisfy these distribution requirements. This limits the amount of cash we have available for other business purposes, including amounts to fund growth.

Aimco’s charter and Maryland law may limit the ability of a third party to acquire control of Aimco and, therefore, the Partnership.

A third party is not likely to make an offer to acquire the Partnership unless that third party is also acquiring control of Aimco. The 8.7% ownership limit in Aimco’s charter may have the effect of delaying or precluding acquisition of control of Aimco by a third party without the consent of Aimco’s board of directors. Aimco’s charter authorizes its board of directors to issue up to 510,587,500 shares of capital stock. As of December 31, 2009, 426,157,736 shares were classified as Aimco Class A Common Stock, of which 116,479,791 were outstanding, and 84,429,764 shares were classified as preferred stock, of which 24,950,134 were outstanding. Under Aimco’s charter, its board of directors has the authority to classify and reclassify any of Aimco’s unissued shares of preferred stock into shares of capital stock with such preferences, conversion or other rights, voting power restrictions, limitation as to dividends, qualifications or terms or conditions of redemptions as Aimco’s board of directors may determine. The authorization and issuance of a new class of capital stock could have the effect of delaying or preventing someone from taking control of Aimco, even if a change in control was in the best interests of Aimco’s stockholders or the Partnership’s Limited Partners.

The Maryland General Corporation Law may limit the ability of a third party to acquire control of Aimco and, therefore, the Partnership.

As noted above, a third party is not likely to make an offer to acquire the Partnership unless that third party is also acquiring control of Aimco. As a Maryland corporation, Aimco is subject to various Maryland laws that may have the effect of discouraging offers to acquire Aimco and of increasing the difficulty of consummating any such offers, even if an acquisition would be in the best interests of Aimco’s stockholders or the Limited Partners. The Maryland General Corporation Law, specifically the Maryland Business Combination Act, restricts mergers and other business combination transactions between Aimco and any person who acquires directly or indirectly beneficial ownership of shares of Aimco’s stock representing 10% or more of the voting power without prior approval of Aimco’s board of directors. Any such business combination transaction could not be completed until five years after the person acquired such voting power, and generally only with the approval of stockholders representing 80% of all votes entitled to be cast and 66 2/3% of the votes entitled to be cast, excluding the interested stockholder, or upon payment of a fair price. The Maryland General Corporation Law, specifically the Maryland Control Share Acquisition Act, provides generally that a person who acquires shares of Aimco’s capital stock representing 10% or more of the voting power in electing directors will have no voting rights unless approved by a vote of two-thirds of the shares eligible to vote. Additionally, the Maryland General Corporation Law provides, among other things, that the board of directors has broad discretion in adopting stockholders’ rights plans and has the sole power to fix the record date, time and place for special meetings of the stockholders. To date, Aimco has not adopted a shareholders’ rights plan. In addition, the Maryland General Corporation Law provides that corporations that:

	•		have at least three directors who are not officers or employees of the entity or related to an acquiring person; and
	•		has a class of equity securities registered under the Securities Exchange Act of 1934, as amended,

may elect in their charter or bylaws or by resolution of the board of directors to be subject to all or part of a special subtitle that provides that:

	•		the corporation will have a staggered board of directors;
	•		any director may be removed only for cause and by the vote of two-thirds of the votes entitled to be cast in the election of directors generally, even if a lesser proportion is provided in the charter or bylaws;
	•		the number of directors may only be set by the board of directors, even if the procedure is contrary to the charter or bylaws;
	•		vacancies may only be filled by the remaining directors, even if the procedure is contrary to the charter or bylaws; and
	•		the secretary of the corporation may call a special meeting of stockholders at the request of stockholders only on the written request of the stockholders entitled to cast at least a majority of all the votes entitled to be cast at the meeting, even if the procedure is contrary to the charter or bylaws.

To date, Aimco has not made any of the elections described above. However, these provisions of Maryland law could have the effect of delaying or preventing someone from taking control of Aimco, even if a change in control was in the best interests of Aimco’s stockholders or the Partnership’s Limited Partners.

At December 31, 2009, we owned an equity interest in and consolidated 426 properties containing 95,202 apartment units, which we refer to as “consolidated properties.” These consolidated properties contain, on average, 223 apartment units, with the largest property containing 2,113 apartment units. These properties offer residents a range of amenities, including swimming pools, clubhouses, spas, fitness centers and tennis courts. Many of the apartment units offer features such as vaulted ceilings, fireplaces, washer and dryer hook-ups, cable television, balconies and patios. Additional information on our consolidated properties is contained in “Schedule III — Real Estate and Accumulated Depreciation” in this Annual Report on Form 10-K. At December 31, 2009, we held an equity interest in and did not consolidate 77 properties containing 8,478 apartment units, which we refer to as “unconsolidated properties.” In addition, we provided property management services for 22 properties containing 2,095 apartment units, and asset management services for 345 properties containing 29,879 apartment units. In certain cases, we may indirectly own generally less than one percent of the economic interest in such properties through a partnership syndication or other fund.

Substantially all of our consolidated properties are encumbered by property debt. At December 31, 2009, our consolidated properties classified as held for use in our consolidated balance sheet were encumbered by aggregate property debt totaling $5,547.3 million having an aggregate weighted average interest rate of 5.50%. Such property debt was collateralized by 412 properties with a combined net book value of $6,868.3 million. Included in the 412 properties, we had a total of 31 property loans on 15 properties, with an aggregate principal balance outstanding of $366.1 million, that were each collateralized by property and cross-collateralized with certain (but not all) other property loans within this group of property loans (see Note 6 of the consolidated financial statements in Item 8 for additional information about our property debt).

Item 3.		Legal Proceedings

PART II

Item 5.		Market for the Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities

There is no public market for the OP Units, and we do not intend to list the OP Units on any securities exchange. In addition, the Partnership Agreement restricts the transferability of OP Units. The following table sets forth the distributions declared per common OP Unit in each quarterly period during the two years ended December 31, 2009 and 2008:

Quarter Ended		2009				2008
December 31		$	0.20			$	3.88	(1)
September 30			0.10				3.00	(1)
June 30			0.10				0.60
March 31			0.00				0.00

Aimco’s board of directors determines and declares Aimco’s dividends. In making a dividend determination, Aimco’s board of directors considers a variety of factors, including: REIT distribution requirements; current market conditions; liquidity needs and other uses of cash, such as for deleveraging and accretive investment activities. Aimco’s board of directors may adjust the dividend amount or the frequency with which the dividend is paid based on then prevailing facts and circumstances. We intend for our distributions to be consistent with Aimco’s dividends.

On February 24, 2010, there were 124,342,598 common OP Units outstanding, held by 2,440 unitholders of record.

Our Partnership Agreement generally provides that after holding the common OP Units for one year, our Limited Partners have the right to redeem their common OP Units for cash, subject to our prior right to cause Aimco 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).

During the three and twelve months ended December 31, 2009, approximately 379,400 and 518,800 common OP Units were redeemed in exchange for an equal number of shares of Aimco Class A Common Stock, respectively. During the three and twelve months ended December 31, 2009, no preferred OP Units were redeemed in exchange for shares of Aimco Class A Common Stock. The following table summarizes repurchases of our equity securities for the three months ended December 31, 2009:

Item 7.		Management’s Discussion and Analysis of Financial Condition and Results of Operations

Executive Overview

We are a limited partnership engaged in the acquisition, ownership, management and redevelopment of apartment properties. We are the operating partnership for Aimco, which is a self-administered and self-managed real estate investment trust, or REIT. Our property operations are characterized by diversification of product, location and price point. We primarily invest in the 20 largest U.S. markets, as measured by total market capitalization, which is the total market value of institutional-grade apartment properties in a particular market. We define these markets as “target markets” and they possess the following characteristics: a high concentration of population and apartment units; geographic and employment diversification; and historically strong returns with reduced volatility as part of a diversified portfolio. We are one of the largest owners and operators of apartment properties in the United States. As of December 31, 2009, we owned or managed 870 apartment properties containing 135,654 units located in 44 states, the District of Columbia and Puerto Rico. Our primary sources of income and cash are rents associated with apartment leases.

The key financial indicators that we use in managing our business and in evaluating our financial condition and operating performance are: NAV; Funds From Operations, or FFO; Adjusted FFO, or AFFO, which is FFO less spending for Capital Replacements; same store property operating results; net operating income; Free Cash Flow, which is net operating income less spending for Capital Replacements; financial coverage ratios; and leverage as shown on our balance sheet. FFO and Capital Replacements are defined and further described in the sections captioned “Funds From Operations” and “Capital Additions” below. The key macro-economic factors and non-financial indicators that affect our financial condition and operating performance are: household formations; rates of job growth; single-family and multifamily housing starts; interest rates; and availability and cost of financing.

Because our operating results depend primarily on income from our properties, the supply and demand for apartments influences our operating results. Additionally, the level of expenses required to operate and maintain our properties and the pace and price at which we redevelop, acquire and dispose of our apartment properties affect our operating results. Our cost of capital is affected by the conditions in the capital and credit markets and the terms that we negotiate for our equity and debt financings.

During the challenging financial and economic environment in 2009, we focused on: serving and retaining residents; continually improving our portfolio; reducing leverage and financial risk; and simplifying our business model.

We are focused on owning and operating B/B+ quality apartments concentrated in our target markets. We intend to upgrade the quality of our portfolio through the sale of approximately 5% to 10% of our portfolio annually, with the proceeds generally used to increase our allocation of capital to well located properties within our target markets through capital investments, redevelopment or acquisitions.

The following discussion and analysis of the results of our operations and financial condition should be read in conjunction with the accompanying consolidated financial statements in Item 8.

Results of Operations

Overview

2009 compared to 2008

We reported net loss attributable to the Partnership of $66.4 million and net loss attributable to the Partnership’s common unitholders of $123.3 million for the year ended December 31, 2009, compared to net income attributable to the Partnership of $472.0 million and net income attributable to the Partnership’s common unitholders of $403.7 million for the year ended December 31, 2008, decreases of $538.4 million and $527.0 million, respectively. These decreases were principally due to the following items, all of which are discussed in further detail below:

	•		a decrease in income from discontinued operations, primarily related to our sale of fewer assets in 2009 and the recognition of gains on sales as compared to 2008;
	•		a decrease in gain on dispositions of unconsolidated real estate and other, primarily due to a large gain on the sale of an interest in an unconsolidated real estate partnership in 2008;
	•		an increase in depreciation and amortization expense, primarily related to completed redevelopments and capital additions placed in service for partial periods during 2008 and 2009; and
	•		a decrease in asset management and tax credit revenues, primarily due to a reduction in promote income, which is income earned in connection with the disposition of properties owned by our consolidated joint ventures.

The effects of these items on our operating results were partially offset by:

	•		a decrease in earnings allocable to noncontrolling interests, primarily due to a decrease in the noncontrolling interests’ share of the decrease in gains on sales discussed above;
	•		a decrease in general and administrative expenses, primarily related to reductions in personnel and related expenses from our organizational restructuring activities during 2008 and 2009; and
	•		impairment losses on real estate development assets in 2008, for which no similar impairments were recognized in 2009.

2008 compared to 2007

We reported net income attributable to the Partnership of $472.0 million and net income attributable to the Partnership’s Aimco common unitholders of $403.7 million for the year ended December 31, 2008, compared to net income attributable to the Partnership of $34.1 million and net loss attributable to the Partnership’s common unitholders of $43.5 million for the year ended December 31, 2007, increases of $437.9 million and $447.2 million, respectively. These increases were principally due to the following items, all of which are discussed in further detail below:

	•		an increase in income from discontinued operations, primarily related to an increase in the number of assets sold during 2008 and our recognition of higher gains on sales as compared to 2007;
	•		an increase in gain on dispositions of unconsolidated real estate and other, primarily due to a large gain on the sale of an interest in an unconsolidated real estate partnership in 2008;
	•		an increase in net operating income associated with property operations, reflecting improved operations of our same store properties and other properties; and
	•		an increase in asset management and tax credit revenues, primarily due to an increase in promote income, which is income earned in connection with the disposition of properties owned by our consolidated joint ventures.

The effects of these items on our operating results were partially offset by:

	•		impairment losses on real estate development assets in 2008, for which no similar impairments were recognized in 2007;
	•		an increase in earnings allocable to noncontrolling interests, primarily due to an increase in the noncontrolling interests’ share of the increase in gains on sales discussed above;
	•		an increase in depreciation and amortization expense, primarily related to completed redevelopments placed in service for partial periods during 2007 or 2008;
	•		restructuring costs recognized during the fourth quarter of 2008; and
	•		an increase in provisions for losses on notes receivable, primarily due to the impairment during 2008 of our interest in Casden Properties LLC.

The following paragraphs discuss these and other items affecting the results of our operations in more detail.

Business Segment Operating Results

We have two reportable segments: real estate (owning, operating and redeveloping apartments) and investment management (portfolio management and asset management). Our chief operating decision maker uses various generally accepted industry financial measures to assess the performance and financial condition of the business, including: NAV; FFO; AFFO; same store property operating results; net operating income; Free Cash Flow; financial coverage ratios; and leverage as shown on our balance sheet. Our chief operating decision maker emphasizes net operating income as a key measurement of segment profit or loss. Segment net operating income is generally defined as segment revenues less direct segment operating expenses.

Real Estate Segment

Our real estate segment involves the ownership and operation of properties that generate rental and other property-related income through the leasing of apartment units. Our real estate segment’s net operating income also includes income from property management services performed for unconsolidated partnerships and unrelated parties.

The following table summarizes our real estate segment’s net operating income for the years ended December 31, 2009, 2008 and 2007 (in thousands):

		Year Ended December 31,
		2009				2008				2007
Real estate segment revenues:
Rental and other property revenues		$	1,140,828			$	1,137,995			$	1,093,779
Property management revenues, primarily from affiliates			5,082				6,345				6,923
			1,145,910				1,144,340				1,100,702
Real estate segment expenses:
Property operating expenses			521,161				526,238				503,890
Property management expenses			2,869				5,385				6,678
			524,030				531,623				510,568
Real estate segment net operating income		$	621,880			$	612,717			$	590,134

For the year ended December 31, 2009, compared to the year ended December 31, 2008, real estate segment net operating income increased $9.2 million, or 1.5%. This increase was due to an increase in real estate segment revenues of $1.6 million, or 0.1% and a decrease in real estate segment expenses of $7.6 million, or 1.4%.

The increase in revenues from our real estate segment during the year ended December 31, 2009, was primarily attributed to an increase of $10.0 million in revenues related to our conventional redevelopment properties based on more units in service at these properties in 2009, $7.5 million in revenues related to our affordable properties, primarily due to higher average rents partially offset by lower physical occupancy during 2009, and $2.3 million of revenues related to properties acquired during the latter half of 2008. These increases were partially offset by a $14.8 million, or 2.0%, decrease in revenues from our conventional same store properties, due to a decrease of 50 basis points in average physical occupancy and lower average rent (approximately $23 per unit). Conventional same store property revenues in our target markets, which represented approximately 78% of our total conventional same store revenues, decreased by 2.7% due to decreases in average physical occupancy (80 basis points) and average rent (approximately $31 per unit). The decrease in revenues associated with these target markets were primarily attributed to revenue decreases of 4.9% in our Pacific markets, attributed to 140 basis points in lower occupancy and $73 per unit in lower rents, and 3.3% in our Sunbelt market, attributed to 40 basis points in lower occupancy and $35 per unit in lower rents. Conventional same store revenues related to our other markets decreased by 1.7%, due to 130 basis points in lower occupancy and $14 per unit in lower rents.

For the year ended December 31, 2009, compared to the year ended December 31, 2008, the decrease in our real estate segment expenses was primarily attributed to property management expenses. Property management expenses related to our consolidated properties, which are shown in the table above as a component of property operating expenses, decreased by $8.2 million, and property management expenses related to our unconsolidated properties decreased by $2.5 million, both due primarily to reductions in personnel and related costs resulting from our organizational restructurings. These decreases in our real estate segment expenses were partially offset by increases of $0.6 million related to our conventional same store properties, primarily due to increases in employee compensation, insurance, repair and maintenance, and real estate tax expenses, offset by decreases in administrative and marketing expenses, $0.6 million related to our conventional redevelopment properties, primarily due to more units placed in service, $0.5 million related to our affordable properties, primarily due to properties that were newly consolidated in 2008 and $0.8 million related to properties acquired during the latter half of 2008.

For the year ended December 31, 2008, compared to the year ended December 31, 2007, real estate segment net operating income increased $22.6 million, or 3.8%. This increase was due to an increase in real estate segment revenues of $43.6 million, or 4.0%, offset by an increase in real estate segment expenses of $21.1 million, or 4.1%.

The increase in revenues from our real estate segment during the year ended December 31, 2008, was primarily attributed to an increase of $19.8 million in revenues from our conventional same store properties, due to an increase of 80 basis points in average physical occupancy and higher average rent (approximately $18 per unit), $13.0 million in revenues related to our affordable properties, primarily due to newly consolidated properties, and $8.8 million in revenues related to our conventional redevelopment properties based on more units in service and higher rental rates.

For the year ended December 31, 2008, compared to the year ended December 31, 2007, the increase in expense was primarily attributed to increases of $9.3 million related to our affordable properties, primarily due to properties that were newly consolidated, $5.2 million related to our conventional redevelopment properties, primarily due to more units placed in service, $3.1 million of property management expenses related to consolidated properties, which are shown in the table above as a component of property operating expenses, and $0.2 million related to our conventional same store properties, primarily due to increases in utilities and real estate taxes, offset by decreases in employee compensation, repairs and maintenance, and turnover expenses. These increases in property expenses were in addition to an increase of $4.2 million in casualty losses during 2008, primarily related to properties damaged by Tropical Storm Fay and Hurricane Ike.

Investment Management Segment

Our investment management segment includes activities and services related to our owned portfolio of properties as well as services provided to affiliated partnerships. Activities and services that fall within investment management include portfolio strategy, capital allocation, joint ventures, tax credit syndication, acquisitions, dispositions and other transaction activities. Within our owned portfolio, we refer to these activities as “Portfolio Management,” and their benefit is seen in property operating results and in investment gains. For affiliated partnerships, we refer to these activities as asset management, for which we are separately compensated through fees paid by third party investors. The expenses of this segment consist primarily of the costs of departments that perform these activities. These activities are conducted in part by our taxable subsidiaries, and the related net operating income may be subject to income taxes.

Asset management revenue includes certain fees that were earned in a prior period, but not recognized at that time because collectibility was not reasonably assured. Those fees may be recognized in a subsequent period upon occurrence of a transaction or a high level of the probability of occurrence of a transaction, or improvement in operations that generates sufficient cash to pay the fees.

The following table summarizes the net operating income from our investment management segment for the years ended December 31, 2009, 2008 and 2007 (in thousands):

		Year Ended December 31,
		2009				2008				2007
Asset management and tax credit revenues		$	52,193			$	101,225			$	73,755
Investment management expenses			15,779				24,784				20,507
Investment segment net operating income		$	36,414			$	76,441			$	53,248

For the year ended December 31, 2009, compared to the year ended December 31, 2008, net operating income from investment management decreased $40.0 million, or 52.4%. This decrease is primarily attributable to a $42.8 million decrease in promote income, which is income earned in connection with the disposition of properties owned by our consolidated joint ventures, due to fewer related sales in 2009 and a $7.6 million decrease in other general partner transactional fees, partially offset by a $9.0 million decrease in investment management expenses, primarily due to reductions in personnel and related costs from our organizational restructurings and a reduction in transaction costs, and a $3.9 million increase in revenues associated with our affordable housing tax credit syndication business, including syndication fees and other revenue earned in connection with these arrangements.

For the year ended December 31, 2008, compared to the year ended December 31, 2007, net operating income from investment management increased $23.2 million, or 43.6%. This increase is primarily attributable to a $30.7 million increase in promote income, which is income earned in connection with the disposition of properties owned by our consolidated joint ventures, and a $9.2 million increase in other general partner transactional fees. These increases are offset by a decrease of $7.4 million in asset management fees, a decrease of $5.0 million in revenues associated with our affordable housing tax credit syndication business, including syndication fees and other revenue earned in connection with these arrangements, and an increase of $4.3 million in investment management expenses, inclusive of $3.5 million in deferred acquisition costs.

Other Operating Expenses (Income)

Depreciation and Amortization

For the year ended December 31, 2009, compared to the year ended December 31, 2008, depreciation and amortization increased $51.4 million, or 13.1%. This increase primarily consists of depreciation related to properties acquired during the latter part of 2008, completed redevelopments and other capital projects recently placed in service.

For the year ended December 31, 2008, compared to the year ended December 31, 2007, depreciation and amortization increased $45.5 million, or 13.1%. This increase reflects depreciation of $65.3 million for newly acquired properties, completed redevelopments and other capital projects recently placed in service. This increase was partially offset by a decrease of $25.7 million in depreciation adjustments necessary to reduce the carrying amount of buildings and improvements to their estimated disposition value, or zero in the case of a planned demolition, primarily due to a property that became fully depreciated during 2007.

Provision for Operating Real Estate Impairment Losses

Real estate and other long-lived assets to be held and used are stated at cost, less accumulated depreciation and amortization, unless the carrying amount of the asset is not recoverable. If events or circumstances indicate that the carrying amount of a property may not be recoverable, we make an assessment of its recoverability by comparing the carrying amount to our estimate of the undiscounted future cash flows, excluding interest charges, of the property. If the carrying amount exceeds the estimated aggregate undiscounted future cash flows, we recognize an impairment loss to the extent the carrying amount exceeds the estimated fair value of the property.

For the years ended December 31, 2009 and 2007, we recognized impairment losses of $2.3 million and $1.1 million, respectively, related to properties classified as held for use as of December 31, 2009. We recognized no such impairment losses during the year ended December 31, 2008.

Provision for Impairment Losses on Real Estate Development Assets

In connection with the preparation of our 2008 annual financial statements, we assessed the recoverability of our investment in our Lincoln Place property, located in Venice, California. Based upon the decline in land values in Southern California during 2008 and the expected timing of our redevelopment efforts, we determined that the total carrying amount of the property was no longer probable of full recovery and, accordingly, during the three months ended December 31, 2008, recognized an impairment loss of $85.4 million ($55.6 million net of tax).

Similarly, we assessed the recoverability of our investment in Pacific Bay Vistas (formerly Treetops), a vacant property located in San Bruno, California, and determined that the carrying amount of the property was no longer probable of full recovery and, accordingly, we recognized an impairment loss of $5.7 million for this property during the three months ended December 31, 2008.

The impairments discussed above totaled $91.1 million and are included in provisions for impairment losses on real estate development assets in our consolidated statement of income for the year ended December 31, 2009 included in Item 8. We recognized no similar impairments on real estate development assets during the years ended December 31, 2009 or 2007.

General and Administrative Expenses

For the year ended December 31, 2009, compared to the year ended December 31, 2008, general and administrative expenses decreased $29.6 million, or 29.8%. This decrease is primarily attributable to reductions in personnel and related expenses associated with our organizational restructurings (see Note 3 to the consolidated financial statements in Item 8), pursuant to which we eliminated approximately 400, or 36%, of our offsite positions between December 31, 2008 and December 31, 2009.

For the year ended December 31, 2008, compared to the year ended December 31, 2007, general and administrative expenses increased $8.5 million, or 9.4%. This increase is primarily attributable to higher personnel and related expenses of $6.1 million and an increase of $1.5 million in information technology communications costs.

Other Expenses, Net

Other expenses, net includes franchise taxes, risk management activities, partnership administration expenses and certain non-recurring items.

For the year ended December 31, 2009, compared to the year ended December 31, 2008, other expenses, net decreased by $4.7 million. The decrease is primarily attributable to a $5.4 million write-off during 2008 of certain communications hardware and capitalized costs in 2008, and a $5.3 million reduction in expenses of our self insurance activities, including a decrease in casualty losses on less than wholly owned properties from 2008 to 2009. These decreases are partially offset by an increase of $4.3 million in costs related to certain litigation matters.

For the year ended December 31, 2008, compared to the year ended December 31, 2007, other expenses, net increased by $3.2 million. The increase includes a $5.4 million write-off of certain communications hardware and capitalized costs during 2008 and a $1.2 million write-off of redevelopment costs associated with a change in the planned use of a property during 2008. The net unfavorable change also reflects $3.6 million of income recognized in 2007 related to the transfer of certain property rights to an unrelated party. These increases were partially offset by a $3.7 million reduction in expenses of our self insurance activities (net of costs in 2008 related to Tropical Storm Fay and Hurricane Ike) and a net decrease of $1.7 million in costs related to certain litigation matters.

Restructuring Costs

For the year ended December 31, 2009, we recognized restructuring costs of $11.2 million, as compared to $22.8 million in the year ended December 31, 2008, related to our organizational restructurings, which are further discussed in Note 3 to the consolidated financial statements in Item 8. We recognized no restructuring costs during the year ended December 31, 2007.

Interest Income

Interest income consists primarily of interest on notes receivable from non-affiliates and unconsolidated real estate partnerships, interest on cash and restricted cash accounts, and accretion of discounts on certain notes receivable from unconsolidated real estate partnerships. Transactions that result in accretion occur infrequently and thus accretion income may vary from period to period.

For the year ended December 31, 2009, compared to the year ended December 31, 2008, interest income decreased $10.5 million, or 50.9%. Interest income decreased by $8.7 million due to lower interest rates on notes receivable, cash and restricted cash balances and lower average balances and by $4.1 million due to a decrease in accretion income related to our note receivable from Casden Properties LLC for which we ceased accretion following impairment of the note in 2008. These decreases were partially offset by a $2.3 million increase in accretion income related to other notes during the year ended December 31, 2008, resulting from a change in the timing and amount of collection.

For the year ended December 31, 2008, as compared to the year ended December 31, 2007, interest income decreased $23.3 million, or 52.9%. Interest income decreased by $16.0 million due to lower interest rates on notes receivable, cash and restricted cash balances and lower average balances. Interest income also decreased by $5.8 million due to an adjustment of accretion on certain discounted notes during the year ended December 31, 2008, resulting from a change in the estimated timing and amount of collection, and by $1.5 million for accretion income recognized during the year ended December 31, 2007, related to the prepayment of principal on certain discounted loans collateralized by properties in West Harlem in New York City.

Provision for Losses on Notes Receivable

During the years ended December 31, 2009, 2008 and 2007, we recognized net provisions for losses on notes receivable of $21.5 million, $17.6 million and $2.0 million, respectively. The provisions for losses on notes receivable for the years ended December 31, 2009 and 2008, primarily consist of impairments related to our investment in Casden Properties LLC, which are discussed further below.

As part of the March 2002 acquisition of Casden Properties, Inc., we invested $50.0 million for a 20% passive interest in Casden Properties LLC, an entity organized to acquire, re-entitle and develop land parcels in Southern California. Based upon the profit allocation agreement, we account for this investment as a note receivable and through 2008 were amortizing the discounted value of the investment to the $50.0 million previously estimated to be collectible, through January 2, 2009, the initial dissolution date of the entity. In 2009, the managing member extended the dissolution date. In connection with the preparation of our 2008 annual financial statements and as a result of a decline in land values in Southern California, we determined our recorded investment amount was not fully recoverable, and accordingly recognized an impairment loss of $16.3 million ($10.0 million net of tax) during the three months ended December 31, 2008. In connection with the preparation of our 2009 annual financial statements and as a result of continued declines in land values in Southern California, we determined our then recorded investment amount was not fully recoverable, and accordingly recognized an impairment loss of $20.7 million ($12.4 million net of tax) during the three months ended December 31, 2009.

In addition to the impairments related to Casden Properties LLC discussed above, we recognized provisions for losses on notes receivable totaling $0.8 million, $1.3 million and $2.0 million during the years ended December 31, 2009, 2008 and 2007, respectively.

Interest Expense

For the years ended December 31, 2009 and December 31, 2008, interest expense, which includes the amortization of deferred financing costs, totaled $324.2 million and $324.1 million, respectively. Interest expense increased by $15.0 million due to a reduction in redevelopment activity during 2009, which resulted in a reduction in capitalized interest. In addition, interest expense increased by $1.2 million due to an increase in prepayment penalties associated with refinancing activities, from $2.8 million in 2008 to $4.0 million in 2009, and by $3.3 million related to non-recourse property loans, from $311.2 million to $314.5 million, primarily due to higher average interest rates partially offset by lower average balances during 2009. These increases in interest expense were substantially offset by decreases in corporate interest expense. Interest expense related to corporate debt, which is primarily floating rate, decreased by $19.4 million, from $34.8 million to $15.4 million, primarily due to lower average balances and interest rates during 2009.

For the year ended December 31, 2008, compared to the year ended December 31, 2007, interest expense increased $11.1 million, or 3.5%. Interest expense related to non-recourse property loans increased by $17.1 million, from $294.1 million to $311.2 million, primarily due to higher average balances partially offset by lower average interest rates during 2008. In addition, interest expense increased by $4.4 million, due to a decrease in capitalized interest from $29.1 million in 2007 to $24.7 million in 2008, resulting from more units in service and lower interest rates. These increases were partially offset by a decrease in interest expense related to corporate debt, which is primarily floating rate and which decreased by $10.4 million, from $45.2 million to $34.8 million, primarily due to lower average balances and interest rates during 2008.

Equity in Losses of Unconsolidated Real Estate Partnerships

Equity in losses of unconsolidated real estate partnerships includes our share of net losses of our unconsolidated real estate partnerships and is primarily driven by depreciation expense in excess of the net operating income recognized by such partnerships.

During the years ended December 31, 2009, 2008 and 2007, we recognized equity in losses of unconsolidated real estate partnerships of $12.0 million, $4.6 million and $3.3 million, respectively. The $7.4 million increase in our equity in losses from 2008 to 2009 was primarily due to our sale in late 2008 of an interest in an unconsolidated real estate partnership that generated $3.0 million of equity in earnings during the year ended December 31, 2008, and our sale during 2009 of our interest in an unconsolidated group purchasing organization which resulted in a decrease of equity in earnings of approximately $1.2 million. The increase in equity in losses also includes additional losses recognized during 2009 related to the underlying investment properties of certain tax credit syndications we consolidated during 2009 and 2008.

Impairment Losses Related to Unconsolidated Real Estate Partnerships

Impairment losses related to unconsolidated real estate partnerships includes our share of impairment losses recognized by our unconsolidated real estate partnerships. For the year ended December 31, 2009, compared to the year ended December 31, 2008, impairment losses related to unconsolidated real estate partnerships decreased $2.3 million, and for the year ended December 31, 2008, compared to the year ended December 31, 2007, impairment losses related to unconsolidated real estate partnerships increased $2.7 million. This decrease and increase are primarily attributable to impairment losses recognized by unconsolidated partnerships on their underlying real estate properties during 2008.

Gain on Dispositions of Unconsolidated Real Estate and Other

Gain on dispositions of unconsolidated real estate and other includes our share of gains related to dispositions of real estate by unconsolidated real estate partnerships, gains on disposition of interests in unconsolidated real estate partnerships, gains on dispositions of land and other non-depreciable assets and costs related to asset disposal activities. Changes in the level of gains recognized from period to period reflect the changing level of disposition activity from period to period. Additionally, gains on properties sold are determined on an individual property basis or in the aggregate for a group of properties that are sold in a single transaction, and are not comparable period to period.

For the year ended December 31, 2009, compared to the year ended December 31, 2008, gain on dispositions of unconsolidated real estate and other decreased $77.4 million. This decrease is primarily attributable to a gain of $98.4 million on our disposition in 2008 of interests in two unconsolidated real estate partnerships. This decrease was partially offset by $18.7 million of gains on the disposition of interests in unconsolidated partnerships during 2009. Gains recognized in 2009 consist of $8.6 million related to our receipt in 2009 of additional proceeds related to our disposition during 2008 of one of the partnership interests discussed above (see Note 3 to the consolidated financials statements in Item 8), $4.0 million from the disposition of our interest in a group purchasing organization (see Note 3 to the consolidated financial statements in Item 8), and $6.1 million from our disposition in 2009 of interests in unconsolidated real estate partnerships.

For the year ended December 31, 2008, compared to the year ended December 31, 2007, gain on dispositions of unconsolidated real estate and other increased $75.4 million. This increase is primarily attributable to a $98.4 million net gain on the disposition of interests in two unconsolidated real estate partnerships during the year ended December 31, 2008. During 2007, we recognized a $6.0 million non-refundable option and extension fee resulting from the termination of rights under an option agreement to sell the North and Central towers of our Flamingo South Beach property, approximately $6.4 million of net gains on dispositions of land parcels and our share of gains on dispositions of properties by unconsolidated real estate partnerships in 2007, and a $10.6 million gain on debt extinguishment related to properties in the VMS partnership (see Note 3 to the consolidated financial statements in Item 8).

Income Tax Benefit

In conjunction with Aimco’s UPREIT structure, certain of our operations, or a portion thereof, such as property management, asset management and risk management, are conducted through, and certain of our properties are owned by, taxable subsidiaries. Income taxes related to the results of continuing operations of our taxable subsidiaries are included in income tax benefit in our consolidated statements of income.

For the year ended December 31, 2009, compared to the year ended December 31, 2008, income tax benefit decreased by $34.5 million. This decrease was primarily attributed to $36.1 million of income tax benefit recognized in 2008 related to the impairments of our Lincoln Place property and our investment in Casden Properties LLC, both of which are owned through taxable subsidiaries, partially offset by $8.1 million of income tax benefit recognized in 2009 related to the impairment of our investment in Casden Properties LLC.

For the year ended December 31, 2008, compared to the year ended December 31, 2007, income tax benefit increased by $33.4 million. This increase was primarily attributed to $36.1 million of income tax benefit recognized in 2008 related to the impairments of our Lincoln Place property and our investment in Casden Properties LLC.

Income from Discontinued Operations, Net

The results of operations for properties sold during the period or designated as held for sale at the end of the period are generally required to be classified as discontinued operations for all periods presented. The components of net earnings that are classified as discontinued operations include all property-related revenues and operating expenses, depreciation expense recognized prior to the classification as held for sale, property-specific interest expense and debt extinguishment gains and losses to the extent there is secured debt on the property. In addition, any impairment losses on assets held for sale and the net gain or loss on the eventual disposal of properties held for sale are reported in discontinued operations.

For the years ended December 31, 2009 and 2008, income from discontinued operations totaled $152.2 million and $744.9 million, respectively. The $592.7 million decrease in income from discontinued operations was principally due to a $541.2 million decrease in gain on dispositions of real estate, net of income taxes, primarily attributable to fewer properties sold in 2009 as compared to 2008, and a $111.8 million decrease in operating income (inclusive of a $27.1 million increase in real estate impairment losses), partially offset by a $58.8 million decrease in interest expense.

For the years ended December 31, 2008 and 2007, income from discontinued operations totaled $744.9 million and $171.6 million, respectively. The $573.3 million increase in income from discontinued operations was principally due to a $641.7 million increase in gain on dispositions of real estate, net of income taxes, primarily attributable to more properties sold in 2008 as compared to 2007 and a $27.9 million decrease in interest expense. These increases were partially offset by a $66.1 million decrease in operating income (inclusive of a $22.0 million increase in real estate impairment losses) and a $31.6 million decrease related to a 2007 gain on debt extinguishment related to properties in the VMS partnership.

During the year ended December 31, 2009, we sold 89 consolidated properties for gross proceeds of $1.3 billion and net proceeds of $432.7 million, resulting in a net gain on sale of approximately $216.0 million (which is net of $5.8 million of related income taxes). During the year ended December 31, 2008, we sold 151 consolidated properties for gross proceeds of $2.4 billion and net proceeds of $1.1 billion, resulting in a net gain on sale of approximately $757.2 million (which is net of $43.1 million of related income taxes). During the year ended December 31, 2007, we sold 73 consolidated properties for gross proceeds of $480.0 million and net proceeds of $203.8 million, resulting in a net gain on sale of approximately $115.5 million (which is net of $2.1 million of related income taxes).

For the years ended December 31, 2009, 2008 and 2007, income from discontinued operations includes the operating results of the properties sold or classified as held for sale as of December 31, 2009.

Changes in the level of gains recognized from period to period reflect the changing level of our disposition activity from period to period. Additionally, gains on properties sold are determined on an individual property basis or in the aggregate for a group of properties that are sold in a single transaction, and are not comparable period to period (see Note 13 of the consolidated financial statements in Item 8 for additional information on discontinued operations).

Noncontrolling Interests in Consolidated Real Estate Partnerships

Noncontrolling interests in consolidated real estate partnerships reflects the non-Aimco partners’, or noncontrolling partners’, share of operating results of consolidated real estate partnerships. This generally includes the noncontrolling partners’ share of property management fees, interest on notes and other amounts eliminated in consolidation that we charge to such partnerships. As discussed in Note 2 to the consolidated financial statements in Item 8, we adopted the provisions of SFAS 160, which are now codified in the Financial Accounting Standards Board’s Accounting Standards Codification, or FASB ASC, Topic 810, effective January 1, 2009. Prior to our adoption of SFAS 160, we generally did not recognize a benefit for the noncontrolling interest partners’ share of partnership losses for partnerships that have deficit noncontrolling interest balances and we generally recognized a charge to our earnings for distributions paid to noncontrolling partners for partnerships that had deficit noncontrolling interest balances. Under the updated provisions of FASB ASC Topic 810, we are required to attribute losses to noncontrolling interests even if such attribution would result in a deficit noncontrolling interest balance and we are no longer required to recognize a charge to our earnings for distributions paid to noncontrolling partners for partnerships that have deficit noncontrolling interest balances.

For the year ended December 31, 2009, compared to the year ended December 31, 2008, net earnings attributed to noncontrolling interests in consolidated real estate partnerships decreased by $133.3 million. This decrease is primarily attributable to a reduction of $108.7 million related to the noncontrolling interests in consolidated real estate partnerships’ share of gains on dispositions of real estate, due primarily to fewer sales in 2009 as compared to 2008, $5.5 million of losses allocated to noncontrolling interests in 2009 that we would not have allocated to the noncontrolling interest partners in 2008 because to do so would have resulted in deficits in their noncontrolling interest balances, and approximately $3.8 million related to deficit distribution charges recognized as a reduction to our earnings in 2008, for which we did not recognize similar charges in 2009 based on the change in accounting discussed above. These decreases are in addition to the noncontrolling interest partners’ share of increased losses of our consolidated real estate partnerships in 2009 as compared to 2008.

For the year ended December 31, 2008, compared to the year ended December 31, 2007, net income attributed to noncontrolling interests in consolidated real estate partnerships increased by $63.6 million. This increase is primarily attributable to an increase of $106.5 million related to the noncontrolling interests in consolidated real estate partnerships’ share of gains on dispositions of real estate, due primarily to more sales in 2008 as compared to 2007, partially offset by increases of $42.9 million in net recoveries of deficit distributions.

As discussed in Note 2 to the consolidated financial statements in Item 8, during the first quarter 2010, we will adopt new accounting guidance related to accounting for variable interest entities. This change in accounting guidance may result in our consolidation of certain previously unconsolidated entities as well as our deconsolidation of certain we currently consolidate. At this time, we have not yet determined the effect this accounting change will have on our consolidated financial statements.

Critical Accounting Policies and Estimates

We prepare our consolidated financial statements in accordance with accounting principles generally accepted in the United States of America, or GAAP, which requires us to make estimates and assumptions. We believe that the following critical accounting policies involve our more significant judgments and estimates used in the preparation of our consolidated financial statements.

Impairment of Long-Lived Assets

Real estate and other long-lived assets to be held and used are stated at cost, less accumulated depreciation and amortization, unless the carrying amount of the asset is not recoverable. If events or circumstances indicate that the carrying amount of a property may not be recoverable, we make an assessment of its recoverability by comparing the carrying amount to our estimate of the undiscounted future cash flows, excluding interest charges, of the property. If the carrying amount exceeds the estimated aggregate undiscounted future cash flows, we recognize an impairment loss to the extent the carrying amount exceeds the estimated fair value of the property.

From time to time, we have non-revenue producing properties that we hold for future redevelopment. We assess the recoverability of the carrying amount of these redevelopment properties by comparing our estimate of undiscounted future cash flows based on the expected service potential of the redevelopment property upon completion to the carrying amount. In certain instances, we use a probability-weighted approach to determine our estimate of undiscounted future cash flows when alternative courses of action are under consideration. As discussed in Provision for Impairment Losses on Real Estate Development Assets within the preceding discussion of our Results of Operations, during 2008 we recognized impairment losses on our Lincoln Place and Pacific Bay Vistas properties of $85.4 million ($55.6 million net of tax) and $5.7 million, respectively.

Real estate investments are subject to varying degrees of risk. Several factors may adversely affect the economic performance and value of our real estate investments. These factors include:

	•		the general economic climate;
	•		competition from other apartment communities and other housing options;
	•		local conditions, such as loss of jobs or an increase in the supply of apartments, that might adversely affect apartment occupancy or rental rates;
	•		changes in governmental regulations and the related cost of compliance;
	•		increases in operating costs (including real estate taxes) due to inflation and other factors, which may not be offset by increased rents;
	•		changes in tax laws and housing laws, including the enactment of rent control laws or other laws regulating multifamily housing; and
	•		changes in interest rates and the availability of financing.

Any adverse changes in these and other factors could cause an impairment in our long-lived assets, including real estate and investments in unconsolidated real estate partnerships. In addition to the impairments of Lincoln Place and Pacific Bay Vistas discussed above, based on periodic tests of recoverability of long-lived assets, for the years ended December 31, 2009 and 2007, we recorded net impairment losses of $2.3 million and $1.1 million, respectively, related to properties classified as held for use, and during the year ended December 31, 2008, we recorded no additional impairments related to properties held for use.

Notes Receivable and Interest Income Recognition

Notes receivable from unconsolidated real estate partnerships consist primarily of notes receivable from partnerships in which we are the general partner. Notes receivable from non-affiliates consist of notes receivable from unrelated third parties. The ultimate repayment of these notes is subject to a number of variables, including the performance and value of the underlying real estate and the claims of unaffiliated mortgage lenders. Our notes receivable include loans extended by us that we carry at the face amount plus accrued interest, which we refer to as “par value notes,” and loans extended by predecessors, some of whose positions we generally acquired at a discount, which we refer to as “discounted notes.”

We record interest income on par value notes as earned in accordance with the terms of the related loan agreements. We discontinue the accrual of interest on such notes when the notes are impaired, as discussed below, or when there is otherwise significant uncertainty as to the collection of interest. We record income on such nonaccrual loans using the cost recovery method, under which we apply cash receipts first to the recorded amount of the loan; thereafter, any additional receipts are recognized as income.

We recognize interest income on discounted notes receivable based upon whether the amount and timing of collections are both probable and reasonably estimable. We consider collections to be probable and reasonably estimable when the borrower has closed transactions or has entered into certain pending transactions (which include real estate sales, refinancings, foreclosures and rights offerings) that provide a reliable source of repayment. In such instances, we recognize accretion income, on a prospective basis using the effective interest method over the estimated remaining term of the loans, equal to the difference between the carrying amount of the discounted notes and the estimated collectible value. We record income on all other discounted notes using the cost recovery method. Accretion income recognized in any given period is based on our ability to complete transactions to monetize the notes receivable and the difference between the carrying value and the estimated collectible amount of the notes; therefore, accretion income varies on a period by period basis and could be lower or higher than in prior periods.

Provision for Losses on Notes Receivable

We assess the collectibility of notes receivable on a periodic basis, which assessment consists primarily of an evaluation of cash flow projections of the borrower to determine whether estimated cash flows are sufficient to repay principal and interest in accordance with the contractual terms of the note. We recognize impairments on notes receivable when it is probable that principal and interest will not be received in accordance with the contractual terms of the loan. The amount of the impairment to be recognized generally is based on the fair value of the partnership’s real estate that represents the primary source of loan repayment. In certain instances where other sources of cash flow are available to repay the loan, the impairment is measured by discounting the estimated cash flows at the loan’s original effective interest rate.

During the years ended December 31, 2009, 2008 and 2007 we recorded net provisions for losses on notes receivable of $21.5 million, $17.6 million and $2.0 million, respectively. As discussed in Provision for Losses on Notes Receivable within the preceding discussion of our Results of Operations, provisions for losses on notes receivable in 2009 and 2008 include impairment losses of $20.7 million ($12.4 million net of tax) and $16.3 million ($10.0 million net of tax), respectively, on our investment in Casden Properties LLC, which we account for as a note receivable. We will continue to evaluate the collectibility of these notes, and we will adjust related allowances in the future due to changes in market conditions and other factors.

Capitalized Costs

We capitalize costs, including certain indirect costs, incurred in connection with our capital additions activities, including redevelopment and construction projects, other tangible property improvements and replacements of existing property components. Included in these capitalized costs are payroll costs associated with time spent by site employees in connection with the planning, execution and control of all capital additions activities at the property level. We characterize as “indirect costs” an allocation of certain department costs, including payroll, at the area operations and corporate levels that clearly relate to capital additions activities. We capitalize interest, property taxes and insurance during periods in which redevelopment and construction projects are in progress. We charge to expense as incurred costs that do not relate to capital additions activities, including ordinary repairs, maintenance, resident turnover costs and general and administrative expenses (see Capital Additions and Related Depreciation in Note 2 to the consolidated financial statements in Item 8).

For the years ended December 31, 2009, 2008 and 2007, for continuing and discontinued operations, we capitalized $9.8 million, $25.7 million and $30.8 million of interest costs, respectively, and $40.0 million, $78.1 million and $78.1 million of site payroll and indirect costs, respectively. The reduction is primarily due to a reduced level of redevelopment activities.

Funds From Operations

FFO is a non-GAAP financial measure that we believe, when considered with the financial statements determined in accordance with GAAP, is helpful to investors in understanding our performance because it captures features particular to real estate performance by recognizing that real estate generally appreciates over time or maintains residual value to a much greater extent than do other depreciable assets such as machinery, computers or other personal property. The Board of Governors of the National Association of Real Estate Investment Trusts, or NAREIT, defines FFO as net income (loss), computed in accordance with GAAP, excluding gains from sales of depreciable property, plus depreciation and amortization, and after adjustments for unconsolidated partnerships and joint ventures. Adjustments for unconsolidated partnerships and joint ventures are calculated to reflect FFO on the same basis. We compute FFO for all periods presented in accordance with the guidance set forth by NAREIT’s April 1, 2002, White Paper, which we refer to as the White Paper. We calculate FFO attributable to the Partnership’s common unitholders (diluted) by subtracting redemption or repurchase related preferred OP Unit issuance costs and distributions on preferred OP Units and adding back distributions on dilutive preferred securities and premiums or discounts on preferred OP Unit redemptions or repurchases. FFO should not be considered an alternative to net income or net cash flows from operating activities, as determined in accordance with GAAP, as an indication of our performance or as a measure of liquidity. FFO is not necessarily indicative of cash available to fund future cash needs. In addition, although FFO is a measure used for comparability in assessing the performance of REITs, there can be no assurance that our basis for computing FFO is comparable with that of other REITs.

For the years ended December 31, 2009, 2008 and 2007, our FFO is calculated as follows (in thousands):

		2009				2008				2007

Notes:

Liquidity and Capital Resources

Liquidity is the ability to meet present and future financial obligations. Our primary source of liquidity is cash flow from our operations. Additional sources are proceeds from property sales and proceeds from refinancings of existing property loans and borrowings under new property loans.

Our principal uses for liquidity include normal operating activities, payments of principal and interest on outstanding debt, capital additions, distributions paid to unitholders and distributions paid to noncontrolling interest partners, repurchases of common OP Units from Aimco in connection with Aimco’s concurrent repurchase of its Class A Common Stock, and acquisitions of, and investments in, properties. We use our cash and cash equivalents and our cash provided by operating activities to meet short-term liquidity needs. In the event that our cash and cash equivalents and cash provided by operating activities are not sufficient to cover our short-term liquidity demands, we have additional means, such as short-term borrowing availability and proceeds from property sales and refinancings, to help us meet our short-term liquidity demands. We may use our revolving credit facility for general corporate purposes and to fund investments on an interim basis. We expect to meet our long-term liquidity requirements, such as debt maturities and property acquisitions, through long-term borrowings, primarily secured, the issuance of equity securities (including OP Units), the sale of properties and cash generated from operations.

The state of credit markets and related effect on the overall economy may have an adverse affect on our liquidity, both through increases in interest rates and credit risk spreads, and access to financing. As further discussed in Item 7A, Quantitative and Qualitative Disclosures About Market Risk, we are subject to interest rate risk associated with certain variable rate liabilities, preferred stock and assets. Based on our net variable rate liabilities, preferred OP Units and assets outstanding at December 31, 2009, we estimate that a 1.0% increase in 30-day LIBOR with constant credit risk spreads would reduce our income attributable to the Partnership’s common unitholders by approximately $1.6 million on an annual basis. Although base interest rates have generally decreased relative to their levels prior to the disruptions in the financial markets, the tightening of credit markets has affected the credit risk spreads charged over base interest rates on, and the availability of, property loan financing. For future refinancing activities, our liquidity and cost of funds may be affected by increases in base interest rates or higher credit risk spreads. If timely property financing options are not available for maturing debt, we may consider alternative sources of liquidity, such as reductions in certain capital spending or proceeds from asset dispositions.

As further discussed in Note 2 to our consolidated financial statements in Item 8, we use total rate of return swaps as a financing product to lower our cost of borrowing through conversion of fixed rate tax-exempt bonds payable and fixed rate notes payable to variable interest rates indexed to the SIFMA rate for tax-exempt bonds payable and the 30-day LIBOR rate for notes payable, plus a credit risk spread. The cost of financing through these arrangements is generally lower than the fixed rate on the debt. As of December 31, 2009, we had total rate of return swap positions with two financial institutions with notional amounts totaling $353.1 million. Swaps with notional amounts of $307.9 million and $45.2 million had maturity dates in May 2012 and October 2012, respectively.

The total rate of return swaps require specified loan-to-value ratios. In the event the values of the real estate properties serving as collateral under these agreements decline or if we sell properties in the collateral pool with low loan-to-value ratios, certain of our consolidated subsidiaries have an obligation to pay down the debt or provide additional collateral pursuant to the swap agreements, which may adversely affect our cash flows. The obligation to provide collateral is limited to these subsidiaries and is non-recourse to us. At December 31, 2009, these subsidiaries were not required to provide cash collateral based on the loan-to-value ratios of the real estate properties serving as collateral under these agreements.

We periodically evaluate counterparty credit risk associated with these arrangements. At the current time, we have concluded we do not have material exposure. In the event a counterparty were to default under these arrangements, loss of the net interest benefit we generally receive under these arrangements, which is equal to the difference between the fixed rate we receive and the variable rate we pay, may adversely affect our operating cash flows.

See Derivative Financial Instruments in Note 2 to the consolidated financial statements in Item 8 for additional discussion of these arrangements, including the current swap maturity dates.

As of December 31, 2009, the amount available under our $180.0 million revolving credit facility was $136.2 million (after giving effect to $43.8 million outstanding for undrawn letters of credit). Our total outstanding term loan of $90.0 million at December 31, 2009, matures in March 2011. We repaid an additional $45.0 million on the term loan through February 26, 2010, leaving a remaining outstanding balance of $45.0 million. Additionally, we have limited obligations to fund redevelopment commitments during the year ending December 31, 2010, and no development commitments.

At December 31, 2009, we had $81.3 million in cash and cash equivalents, a decrease of $218.4 million from December 31, 2008. At December 31, 2009, we had $220.0 million of restricted cash, primarily consisting of reserves and escrows held by lenders for bond sinking funds, capital additions, property taxes and insurance. In addition, cash, cash equivalents and restricted cash are held by partnerships that are not presented on a consolidated basis. The following discussion relates to changes in cash due to operating, investing and financing activities, which are presented in our consolidated statements of cash flows in Item 8.

Operating Activities

For the year ended December 31, 2009, our net cash provided by operating activities of $233.8 million was primarily related to operating income from our consolidated properties, which is affected primarily by rental rates, occupancy levels and operating expenses related to our portfolio of properties, in excess of payments of operating accounts payable and accrued liabilities, including amounts related to our organizational restructuring. Cash provided by operating activities decreased $206.6 million compared with the year ended December 31, 2008, primarily due to a $159.3 million decrease in operating income related to consolidated properties included in discontinued operations, which was attributable to property sales in 2009 and 2008, a $42.8 million decrease in promote income, which is generated by the disposition of properties by consolidated real estate partnerships, and an increase in payments on operating accounts payable and accrued expenses, including payments related to our restructuring accrual, in 2009 as compared to 2008.

Investing Activities

For the year ended December 31, 2009, our net cash provided by investing activities of $630.7 million consisted primarily of proceeds from disposition of real estate and partnership interests, partially offset by capital expenditures.

Although we hold all of our properties for investment, we sell properties when they do not meet our investment criteria or are located in areas that we believe do not justify our continued investment when compared to alternative uses for our capital. During the year ended December 31, 2009, we sold 89 consolidated properties. These properties were sold for an aggregate sales price of $1.3 billion, or $1.2 billion, after the payment of transaction costs and debt prepayment penalties. The $1.2 billion is inclusive of promote income and debt assumed by buyers. Net cash proceeds from property sales were used primarily to repay term debt and for other corporate purposes.

Capital Additions

We classify all capital additions as Capital Replacements (which we refer to as CR), Capital Improvements (which we refer to as CI), casualties or redevelopment. Additions other than casualty or redevelopment capital additions are apportioned between CR and CI based on the useful life of the capital item under consideration and the period we have owned the property.

CR represents the share of capital additions that are deemed to replace the portion of acquired capital assets that was consumed during the period we have owned the asset. CI represents the share of additions that are made to enhance the value, profitability or useful life of an asset as compared to its original purchase condition. CR and CI exclude capital additions for casualties and redevelopment. Casualty additions represent capitalized costs incurred in connection with casualty losses and are associated with the restoration of the asset. A portion of the restoration costs may be reimbursed by insurance carriers subject to deductibles associated with each loss. Redevelopment additions represent additions that substantially upgrade the property.

The table below details our share of actual spending, on both consolidated and unconsolidated real estate partnerships, for CR, CI, casualties and redevelopment for the year ended December 31, 2009, on a per unit and total dollar basis (in thousands, except per unit amounts). Per unit numbers for CR and CI are based on approximately 97,196 average units for the year, including 81,135 conventional units and 16,061 affordable units. Average units are weighted for the portion of the period that we owned an interest in the property, represent ownership-adjusted effective units, and exclude non-managed units.

Included in the above additions for CI, casualties and redevelopment, was approximately $34.6 million of our share of capitalized site payroll and indirect costs related to these activities for the year ended December 31, 2009.

We generally fund capital additions with cash provided by operating activities, working capital and property sales as discussed below.

Financing Activities

For the year ended December 31, 2009, net cash used in financing activities of $1.1 billion was primarily attributed to debt principal payments, distributions paid to common and preferred unitholders and distributions to noncontrolling interests, partially offset by proceeds from property loans.

Property Debt

At December 31, 2009 and 2008, we had $5.6 billion and $6.3 billion, respectively, in consolidated property debt outstanding, which included $29.2 million and $759.3 million, respectively, of property debt classified within liabilities related to assets held for sale. During the year ended December 31, 2009, we refinanced or closed property loans on 55 properties generating $788.1 million of proceeds from borrowings with a weighted average interest rate of 5.78%. Our share of the net proceeds after repayment of existing debt, payment of transaction costs and distributions to limited partners, was $132.3 million. We used these total net proceeds for capital expenditures and other corporate purposes. We intend to continue to refinance property debt primarily as a means of extending current and near term maturities and to finance certain capital projects.

Term Loans and Credit Facility

We have an Amended and Restated Senior Secured Credit Agreement, as amended, with a syndicate of financial institutions, which we refer to as the Credit Agreement.

As of December 31, 2009, the Credit Agreement consisted of aggregate commitments of $270.0 million, comprised of our $90.0 million outstanding balance on the term loan and $180.0 million of revolving loan commitments. The term loan bears interest at LIBOR plus 1.5%, or at our option, a base rate equal to the prime rate, and matures March 2011. Borrowings under the revolving credit facility bear interest based on a pricing grid determined by leverage (either at LIBOR plus 4.25% with a LIBOR floor of 2.00% or, at our option, a base rate equal to the Prime rate plus a spread of 3.00%). The revolving credit facility matures May 1, 2011, and may be extended for an additional year, subject to certain conditions, including payment of a 45.0 basis point fee on the total revolving commitments and repayment of the remaining term loan balance by February 1, 2011.

At December 31, 2009, the term loan had an outstanding principal balance of $90.0 million and an interest rate of 1.73%. We repaid $45.0 million on the term loan through February 26, 2010, leaving a remaining outstanding balance of $45.0 million. At December 31, 2009, we had no outstanding borrowings under the revolving credit facility. The amount available under the revolving credit facility at December 31, 2009, was $136.2 million (after giving effect to $43.8 million outstanding for undrawn letters of credit issued under the revolving credit facility). The proceeds of revolving loans are generally permitted to be used to fund working capital and for other corporate purposes.

Fair Value Measurements

We have entered into total rate of return swaps on various fixed rate secured tax-exempt bonds payable and fixed rate notes payable to convert these borrowings from a fixed rate to a variable rate and provide an efficient financing product to lower our cost of borrowing. We designate total rate of return swaps as hedges of the risk of overall changes in the fair value of the underlying borrowings. At each reporting period, we estimate the fair value of these borrowings and the total rate of return swaps and recognize any changes therein as an adjustment of interest expense.

Our method used to calculate the fair value of the total rate of return swaps generally results in changes in fair value that are equal to the changes in fair value of the related borrowings, which is consistent with our hedging strategy. We believe that these financial instruments are highly effective in offsetting the changes in fair value of the related borrowings during the hedging period, and accordingly, changes in the fair value of these instruments have no material impact on our liquidity, results of operations or capital resources.

During the year ended December 31, 2009, changes in the fair values of these financial instruments resulted in increases of $5.2 million in the carrying amount of the hedged borrowings and equal decreases in accrued liabilities and other for total rate of return swaps. At December 31, 2009, the cumulative recognized changes in the fair value of these financial instruments resulted in a $24.3 million reduction in the carrying amount of the hedged borrowings offset by an equal increase in accrued liabilities and other for total rate of return swaps. The cumulative changes in the fair values of the hedged borrowings and related swaps reflect the recent uncertainty in the credit markets which has decreased demand and increased pricing for similar debt instruments.

During the year ended December 31, 2009, we received net cash receipts of $19.4 million under the total return swaps, which positively affected our liquidity. To the extent interest rates increase above the fixed rates on the underlying borrowings, our obligations under the total return swaps will negatively affect our liquidity. At December 31, 2009, we were not required to provide cash collateral pursuant to the total rate of return swaps. In the event the values of the real estate properties serving as collateral under these agreements decline, we may be required to provide additional collateral pursuant to the swap agreements, which would adversely affect our liquidity.

See Note 2 to the consolidated financial statements in Item 8 for more information on our total rate of return swaps and related borrowings.

Partners’ Capital Transactions

During the year ended December 31, 2009, we paid cash distributions totaling $59.2 million, $116.8 million and $92.4 million to preferred unitholders, common unitholders and noncontrolling interests, respectively. Additionally, we paid distributions totaling $149.0 million to Aimco through the issuance of approximately 15.5 million common OP units.

During the year ended December 31, 2009, Aimco repurchased 12 shares, or $6.0 million in liquidation preference, of its CRA Preferred Stock for $4.2 million. Concurrent with Aimco’s repurchase, we repurchased from Aimco an equivalent number of our CRA Preferred Units.

We and Aimco have a shelf registration statement that provides for the issuance of debt securities by us and debt and equity securities by Aimco.

Contractual Obligations

Total		$	5,753,775			$	122,558			$	772,795			$	874,342			$	3,984,080

In addition to the amounts presented in the table above, at December 31, 2009, we had $690.5 million of outstanding preferred units outstanding with annual dividend yields ranging from 1.5% (variable) to 9.4%, and $85.7 million of redeemable preferred units outstanding with annual distribution yields ranging from 5.9% to 9.5%.

Additionally, we may enter into commitments to purchase goods and services in connection with the operations of our properties. Those commitments generally have terms of one year or less and reflect expenditure levels comparable to our historical expenditures.

Future Capital Needs

In addition to the items set forth in “Contractual Obligations” above, we expect to fund any future acquisitions, additional redevelopment projects, capital improvements and capital replacement principally with proceeds from property sales (including tax-free exchange proceeds), short-term borrowings, debt and equity financing (including tax credit equity) and operating cash flows.

Off-Balance Sheet Arrangements

We own general and limited partner interests in unconsolidated real estate partnerships, in which our total ownership interests typically range from less than 1% to 50% and in some instances may exceed 50%. There are no lines of credit, side agreements, or any other derivative financial instruments related to or between our unconsolidated real estate partnerships and us and no material exposure to financial guarantees. Accordingly, our maximum risk of loss related to these unconsolidated real estate partnerships is limited to the aggregate carrying amount of our investment in the unconsolidated real estate partnerships and any outstanding notes receivable as reported in our consolidated financial statements (see Note 4 of the consolidated financial statements in Item 8 for additional information about our investments in unconsolidated real estate partnerships).

Item 7A.		Quantitative and Qualitative Disclosures About Market Risk

Our primary market risk exposure relates to changes in base interest rates, credit risk spreads and availability of credit. We are not subject to any other material market rate or price risks. We use predominantly long-term, fixed-rate non-recourse property debt in order to avoid the refunding and repricing risks of short-term borrowings. We use short-term debt financing and working capital primarily to fund short-term uses and acquisitions and generally expect to refinance such borrowings with cash from operating activities, property sales proceeds, long-term debt or equity financings. We use total rate-of-return swaps to obtain the benefit of variable rates on certain of our fixed rate debt instruments. We make limited use of other derivative financial instruments and we do not use them for trading or other speculative purposes.

We had $654.6 million of floating rate debt and $67.0 million of floating rate preferred OP Units outstanding at December 31, 2009. Of the total floating rate debt, the major components were floating rate tax-exempt bond financing ($433.9 million), floating rate secured notes ($122.2 million) and a term loan ($90.0 million). At December 31, 2009, we had approximately $440.9 million in cash and cash equivalents, restricted cash and notes receivable, the majority of which bear interest. The effect of our interest-bearing assets would partially reduce the effect of an increase in variable interest rates. Historically, changes in tax-exempt interest rates have been at a ratio of less than 1:1 with changes in taxable interest rates. Floating rate tax-exempt bond financing is benchmarked against the SIFMA rate, which since 1989 has averaged 73% of the 30-day LIBOR rate. If the historical relationship continues, on an annual basis, we estimate that an increase in 30-day LIBOR of 100 basis points (73 basis points for tax-exempt interest rates) with constant credit risk spreads would result in net income and our net income attributable to the Partnership’s common unitholders being reduced by $1.1 million and $1.6 million, respectively.

We estimate the fair value for our debt instruments using present value techniques that include income and market valuation approaches with market rates for debt with the same or similar terms. Present value calculations vary depending on the assumptions used, including the discount rate and estimates of future cash flows. In many cases, the fair value estimates may not be realizable in immediate settlement of the instruments. The estimated aggregate fair value of our consolidated debt (including amounts reported in liabilities related to assets held for sale) was approximately $5.7 billion and $6.7 billion at December 31, 2009 and 2008, respectively. The combined carrying value of our consolidated debt (including amounts reported in liabilities related to assets held for sale) was approximately $5.7 billion and $6.8 billion at December 31, 2009 and 2008, respectively. See Note 6 and Note 7 to the consolidated financial statements in Item 8 for further details on our consolidated debt. Refer to Derivative Financial Instruments in Note 2 to the consolidated financial statements in Item 8 for further discussion regarding certain of our fixed rate debt that is subject to total rate of return swap instruments. If market rates for our fixed-rate debt were higher by 100 basis points with constant credit risk spreads, the estimated fair value of our debt discussed above would have decreased from $5.7 billion to $5.4 billion. If market rates for our debt discussed above were lower by 100 basis points with constant credit risk spreads, the estimated fair value of our fixed-rate debt would have increased from $5.7 billion to $6.1 billion.

At December 31, 2009, we had swap positions with two financial institutions totaling $353.1 million. The related swap agreements provide for collateral calls to maintain specified loan-to-value ratios. In the event the values of the real estate properties serving as collateral under these agreements decline, we may be required to provide additional collateral pursuant to the swap agreements, which would adversely affect our cash flows. At December 31, 2009, we were not required to provide cash collateral based on the loan-to-value ratios of the real estate properties serving as collateral under these agreements.

Item 9A.		Controls and Procedures

Disclosure Controls and Procedures

The Partnership’s management, with the participation of the chief executive officer and chief financial officer of the General Partner, who are the equivalent of the Partnership’s chief executive officer and chief financial officer, respectively, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of the end of the period covered by this report. Based on such evaluation, the chief executive officer and chief financial officer of the General Partner have concluded that, as of the end of such period, our disclosure controls and procedures are effective.

Management’s Report on Internal Control Over Financial Reporting

Management of the Partnership is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is defined in Rule 13a-15(f) and 15d-15(f) under the Exchange Act as a process designed by, or under the supervision of, the General Partner’s principal executive and principal financial officers, or persons performing similar functions, and effected by the General Partner’s board of directors, management and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles and includes those policies and procedures that:

	•		pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Partnership;
	•		provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Partnership are being made only in accordance with authorizations of the General Partner’s management and directors of the Partnership; and
	•		provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Partnership’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Projections of any evaluation of effectiveness to future periods are subject to the risks that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Management assessed the effectiveness of the Partnership’s internal control over financial reporting as of December 31, 2009. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control-Integrated Framework.

Based on the assessment, management concluded that, as of December 31, 2009, the Partnership’s internal control over financial reporting is effective.

The Partnership’s independent registered public accounting firm has issued an attestation report on the Partnership’s internal control over financial reporting.

Changes in Internal Control over Financial Reporting

There has been no change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the fourth quarter of 2009 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

The Partners
AIMCO Properties, L.P.

We have audited AIMCO Properties, L.P.’s (the “Partnership”) internal control over financial reporting as of December 31, 2009, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). The Partnership’s management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Partnership’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, the Partnership maintained, in all material respects, effective internal control over financial reporting as of December 31, 2009, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of the Partnership as of December 31, 2009 and 2008, and the related consolidated statements of income, partners’ capital, and cash flows for each of the three years in the period ended December 31, 2009, and our report dated February 26, 2010 expressed an unqualified opinion thereon.

PART III

Item 10.		Directors, Executive Officers and Corporate Governance

The board of directors of the General Partner consists of Terry Considine and Miles Cortez. The officers of Aimco are also the officers of the General Partner and hold the same titles. The information required by this item is presented under the captions “Board of Directors and Executive Officers” and “Corporate Governance Matters — Code of Ethics” in the proxy statement for Aimco’s 2010 annual meeting of stockholders and is incorporated herein by reference.

Section 16(a) Beneficial Ownership Reporting Compliance. Section 16(a) of the Securities Exchange Act of 1934, as amended, requires the General Partner’s executive officers and directors, and persons who own more than ten percent of a registered class of OP Units, to file reports (Forms 3, 4 and 5) of unit ownership and changes in unit ownership with the Securities and Exchange Commission (“SEC”). Executive officers, directors and beneficial owners of more than ten percent of OP Units are required by SEC regulations to furnish us with copies of all such forms that they file. Based solely on our review of the copies of Forms 3, 4 and 5 and the amendments thereto received by us for the year ended December 31, 2009, or written representations from certain reporting persons that no Forms 5 were required to be filed by those persons, we believe that during the period ended December 31, 2008, all filing requirements were complied with by the General Partner’s executive officers and directors and beneficial owners of more than ten percent of OP Units.

Audit Committee and Nominating and Corporate Governance Committee. The board of directors of the General Partner does not have a separate audit committee or nominating and corporate governance committee. Based on the structure of the Partnership and its relationship to Aimco, which has a separate audit committee and nominating and corporate governance committee, committees are not warranted for the Partnership. The audit committee of Aimco’s board of directors makes determinations concerning the engagement of the independent registered public accounting firm for Aimco and its subsidiaries, including the Partnership. In addition, the Aimco audit committee reviews with the independent registered public accounting firm the plans and results of the audit engagement, reviews the independence of the independent registered public accounting firm, considers the range of audit and non-audit fees and reviews the adequacy of internal control over financial reporting. The Aimco audit committee currently consists of James N. Bailey, Richard S. Ellwood, Thomas L. Keltner, J. Landis Martin, Robert A. Miller and Michael A. Stein. Aimco’s board of directors has determined that Michael A. Stein is an “audit committee financial expert.” Aimco’s board of directors has also determined that each member of the audit committee is independent, as that term is defined by Section 303A of the listing standards of the New York Stock Exchange relating to audit committees.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Partners
AIMCO Properties, L.P.

We have audited the accompanying consolidated balance sheets of AIMCO Properties, L.P. (the “Partnership”) as of December 31, 2009 and 2008, and the related consolidated statements of income, partners’ capital and cash flows for each of the three years in the period ended December 31, 2009. Our audits also included the financial statement schedule listed in the accompanying Index to Financial Statements. These financial statements and schedule are the responsibility of the Partnership’s management. Our responsibility is to express an opinion on these financial statements and schedule based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of the Partnership at December 31, 2009 and 2008, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 2009, in conformity with United States generally accepted accounting principles. Also, in our opinion, the related financial statement schedule, when considered in relation to the basic financial statements taken as a whole, presents fairly, in all material respects the information set forth therein.

The consolidated financial statements include retroactive adjustments to reflect the adoption in 2009 of Statement of Financial Accounting Standards No. 160, Noncontrolling Interests in Consolidated Financial Statements, an amendment to ARB 51 (codified in FASB ASC 810), Statement of Financial Accounting Standards No. 141(R), Business Combinations — a replacement of FASB Statement No 141 (codified in FASB ASC 805), FASB Staff Position No. EITF 03-6-1, Determining Whether Instruments Granted in Share-Based Payment Transactions are Participating Securities (codified in FASB ASC 260), and FASB Accounting Standards Update No. 2010-01, Accounting for Distributions to Shareholders with Components of Stock and Cash (codified in FASB ASC 505). Further, the Partnership retrospectively adjusted the 2008 and 2007 consolidated financial statements to reflect real estate assets that meet the definition of a component and have been sold or meet the criteria to be classified as held for sale at December 31, 2009 pursuant to Statement of Financial Accounting Standards No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets (codified in FASB ASC 360), through December 31, 2009. As discussed in Note 2 to the consolidated financial statements, the consolidated statement of income for the year ended December 31, 2008 has been restated to reclassify provisions for impairment losses on real estate development assets into operating income.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the Partnership’s internal control over financial reporting as of December 31, 2009, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 26, 2010 expressed an unqualified opinion thereon.
