Apartment Investment and Management Company
Announces Fourth Quarter 2010 Results

Denver, Colorado — February 4, 2011 — Apartment Investment and Management Company (NYSE: AIV) announced today its fourth quarter 2010 results.

Chairman, Chief Executive Officer and President Terry Considine comments: “Aimco had a solid 2010. Full year Same Store, Conventional Same Store and Total Portfolio net operating income were all up from the prior year. Total Portfolio revenue was up 1.0% and Conventional Same Store revenue was essentially flat, notwithstanding the fragile economy. Aimco upgraded its portfolio with the sale of 51 properties and ended the year with a strong balance sheet and no recourse debt. Looking forward, the Aimco business plan is straightforward and unchanged: own and operate B/B+ quality apartments in the 20 largest U.S. markets to provide predictable returns for shareholders.”

Chief Financial Officer Ernie Freedman adds: “Fourth quarter Pro forma FFO of $0.39 per share exceeded the upper end of our guidance range by $0.01 per share, primarily as a result of better than expected operating results. We expect 2011 FFO to be in a range from $1.46 to $1.56 per share with first quarter 2011 FFO projected to be $0.33 to $0.37 per share. With a solid 2010 behind us, Aimco is looking ahead to 2011 with a quality portfolio, a strong balance sheet and a focus on future growth opportunities.”

Net income (loss) — Net loss attributable to Aimco common stockholders for the quarter was $38.4 million, compared to net loss of $6.7 million for fourth quarter 2009. Fourth quarter 2010 net loss increased as compared to fourth quarter 2009 primarily due to a decrease of $60.7 million in income from discontinued operations as a result of 2009 and 2010 property sales, partially offset by lower provision for losses on notes receivable of $20.4 million, lower restructuring costs of $8.7 million and an increase of $9.9 million in net operating income of our properties included in continuing operations.

Funds from Operations — FFO is a non-GAAP financial measure defined in the glossary in Aimco’s Supplemental Information (the Glossary). FFO calculated in accordance with the definition prescribed by the National Association of Real Estate Investment Trusts (NAREIT) was $35.7 million, or $0.31 per share, compared to $16.1 million, or $0.14 per share, in fourth quarter 2009. Pro forma FFO, which represents FFO as prescribed by NAREIT but excludes operating real estate impairment losses and preferred equity redemption related amounts, was $45.3 million, or $0.39 per share, compared to $30.2 million, or $0.26 per share, in fourth quarter 2009. Fourth quarter 2010 Pro forma FFO of $0.39 per share was $0.03 per share above the midpoint of Aimco’s guidance range primarily as a result of higher than expected Conventional Same Store average daily occupancy and a reduction in previously estimated real estate tax obligations due to successful appeals completed during the fourth quarter.

Property Operations

Property operating results discussed below represent Aimco’s Proportionate Share of reported amounts, which reflects property operating results adjusted for Aimco’s ownership in each property. This non-GAAP measure is defined in the Glossary.

Diversified Operating Portfolio — Aimco’s property operations consist primarily of Conventional, with some Affordable, real estate operations. Conventional real estate operations relate to Aimco’s diversified portfolio of market rate apartment communities and include Same Store Properties, Redevelopment Properties, and Other Properties. Conventional Property operations generated 88% of Aimco’s fourth quarter 2010 property net operating income (NOI). See Supplemental Schedules 7a and 7b for detailed information on Aimco’s Conventional real estate portfolio, including selected operating results.

Affordable real estate operations consist of Aimco’s portfolio of properties with rents that are generally paid, in whole or in part, by a government agency. Affordable properties tend to have more stable rents and higher occupancy than Conventional properties due to government rent payments and thus are less affected by market fluctuations. Affordable Property operations generated 12% of Aimco’s fourth quarter 2010 NOI.

Comparing Conventional Same Store results in fourth quarter 2010 with fourth quarter 2009, total revenue increased $3.0 million, or 1.6%. The increase in revenue was primarily the result of higher average daily occupancy of 96.7% for fourth quarter 2010 compared to 95.3% for fourth quarter 2009. Higher average daily occupancy was offset by lower average rent per unit, down 0.8% or $8 per unit, from $1,053 per unit to $1,045 per unit.

New and renewal lease rates have steadily improved throughout the year. Rental rates on new leases during the fourth quarter were higher than expiring lease rates each month during the quarter and, on average, fourth quarter new lease rates were 0.9% higher than expiring lease rates. By comparison, new lease rates were 7.0% below expiring lease rates in the first quarter, 2.3% below expiring lease rates in the second quarter, and 1.4% below expiring lease rates in the third quarter. For the full year, new lease rates were on average 2.3% below expiring lease rates.

Fourth quarter renewal rates were 1.6% higher than expiring lease rates. This compares to renewal rates that were 0.1% higher than expiring lease rates in the first quarter, 1.9% higher than expiring lease rates in the second quarter, and 1.5% higher than expiring lease rates in the third quarter. For the full year, renewal rates were on average 1.5% higher than expiring lease rates.

During fourth quarter 2010, Conventional Same Store expenses decreased $2.7 million or 3.7%, primarily as a result of lower real estate taxes, reductions in personnel costs, turnover expenses and marketing costs, partially offset by higher employee-related insurance costs. Refer to Supplemental Schedules 6a through 6c for additional details on Conventional Same Store operating results.

Affordable Same Store Results — In fourth quarter 2010, the Affordable Same Store portfolio included 153 communities with 18,359 units, in which Aimco had a weighted average ownership of 65%. For the fourth quarter 2010, average month-end occupancy for the affordable portfolio was 97.6%, an increase of 0.7% from fourth quarter 2009, while average rent per unit increased 3.8% from $780 to $810 per unit. During the fourth quarter 2010, Affordable Same Store expenses decreased 6.0% primarily as a result of lower contract services and administrative expenses.

Portfolio

Aimco’s portfolio strategy focuses on B/B+ quality Conventional apartment communities located in the 20 largest U.S. markets as measured by total apartment value, with a target capital allocation of 10% to Affordable apartment communities.

Aimco measures Conventional Property asset quality based on average rents compared to local market average rents as reported by REIS, a third-party provider of commercial real estate performance information and analysis. Aimco defines A-quality assets as those with rents greater than 125% of local market average, B-quality assets as those with rents 90% to 125% of local market average and C-quality assets as those with rents less than 90% of local market average. For the third quarter 2010, the most recent period for which REIS information is available, Aimco’s Conventional Property rents averaged 100% of local market average rents.

AIMCO 4th Quarter 2010 Page 3

For the fourth quarter 2010, average rents for the Conventional portfolio were $1,052 per unit, a 1.0% increase compared to fourth quarter 2009, primarily as a result of the sale of Conventional properties during 2010 with rents averaging 25% lower than the retained portfolio.

Aimco’s geographic allocation strategy focuses on the 20 largest U.S. markets. Aimco believes these markets to be deep, relatively liquid and possessing desirable long-term growth characteristics. These target markets are primarily coastal markets, and also include a number of Sun Belt cities and Chicago, Illinois. In executing this strategy, Aimco expects to reduce its investment in markets outside the 20 largest markets and to increase its investment in the 20 largest markets through redevelopment and acquisitions. During fourth quarter 2010, net operating income generated by Conventional properties located in the 20 largest markets accounted for 84.5% of total Conventional Property net operating income, an increase of 1.9% compared to fourth quarter 2009. In fourth quarter 2010, Aimco sold eight Conventional properties and 12 Affordable properties with 1,877 and 1,264 units, respectively, for $117.9 million in gross proceeds. Aimco’s share of net proceeds after distributions to limited partners, repayment of existing property debt and transaction costs was $35.8 million.

See Supplemental Schedules 7a and 7b for additional details regarding Aimco’s portfolio quality and capital allocation, and Supplemental Schedule 8 for additional details on disposition activity.

Partnership Transaction Activity — During fourth quarter 2010, Aimco purchased the noncontrolling limited partners’ interests in two properties for a total of $19.9 million. Aimco purchased the noncontrolling limited partners’ 25% interest in a property located in Alexandria, Virginia, for $19.5 million. The property has 1,222 units and is a candidate for redevelopment in the near term.

See Supplemental Schedules 4a and 4b for additional details about Aimco’s non-recourse property debt and Supplemental Schedule 5 for information related to Aimco’s preferred securities.

Aimco’s recourse debt at December 31, 2010, was limited to its revolving credit facility, which Aimco uses for working capital purposes and to secure letters of credit. At the end of fourth quarter, Aimco had no outstanding borrowings on its revolving credit facility and available capacity was $260.3 million, net of $39.7 million of letters of credit backed by the facility.

Aimco’s fourth quarter EBITDA Coverage of Interest and EBITDA Coverage of Interest and Preferred Dividends ratios were 2.07:1 and 1.68:1, compared to third quarter 2010 ratios of 2.05:1 and 1.67:1, respectively. Separately, in connection with its revolving credit facility, Aimco is subject to Debt Service and Fixed Charge Coverage covenants, as defined in the Glossary. For fourth quarter 2010, Aimco’s Debt Service and Fixed Charge Coverage ratios were 1.57:1 and 1.33:1, compared to covenants in place during the quarter of 1.40:1 and 1.20:1, respectively, and third quarter 2010 ratios of 1.58:1 and 1.34:1. Aimco expects to remain in compliance with these covenants.

During fourth quarter 2010, Aimco issued 600,000 shares under its At-the-Market (ATM) offering program at a weighted average price of $24.50 per share, generating $14.4 million in proceeds. The proceeds from the ATM offering were used primarily to fund the cash portion of the acquisition of the noncontrolling limited partners’ 25% interest in the Alexandria, Virginia property described above.

Dividend — Aimco’s Board of Directors declared a cash dividend of $0.12 per share on its Class A Common Stock for the quarter ended December 31, 2010. The dividend is payable February 28, 2011 to shareholders of record on February 18, 2011.

During 2010, Aimco refinanced certain of the loans subject to the swaps, replacing such loans with long-dated, fixed-rate property debt, and expects to do the same in 2011 with certain other loans subject to the swaps. The average interest rate associated with the total rate of return swaps was 1.58% at December 31, 2010. These activities are expected to increase interest expense in 2011 by $0.06 per share when compared to 2010.

Conventional Same Store Revenue Detail

The following table represents the assumptions used by Aimco in its 2011 guidance for Conventional Same Store revenue growth of 2.0% to 3.0%.

	Conventional Same Store
	Revenue Growth
	(at the midpoint)
Earn in of 2010 leases (New Leasesâ 2.3%, Renewalsá 1.5%)		0.4	%
2011 Projected renewal and new lease rate growth of 3.6%*		1.6	%
Other		0.5	%
Midpoint of 2011 Guidance		2.5	%

* In establishing guidance, Aimco has taken into consideration 2011 revenue growth in its markets as projected by third party data providers, which estimates currently range from 3.1% to 6.2%. Aimco projects that 2011 revenue growth at the low end of this range would produce 2011 Conventional Same Store revenue growth of approximately 2.3%, or 20 basis points less than the midpoint of Aimco’s guidance of 2.5%. Revenue growth at the high end of the third party estimate range would produce 2011 Conventional Same Store revenue growth of approximately 3.7%, or 120 basis points greater than the midpoint of guidance of 2.5%.

Net Asset Value Supplemental Information	(page 2 of 2)
(in thousands) (unaudited)

[1]	Net real estate includes Lincoln Place and Pacific Bay Vistas (formerly Treetops), which are predominantly vacant and have December 31, 2010 net book values of $152.3 million and $36.8 million, respectively, or $189.1 million in total. Aimco refers to these properties collectively as part of its redevelopment pipeline.
[2]	Aimco has notes receivable from consolidated partnerships that are eliminated in the consolidated balance sheet. The noncontrolling partners’ share of amounts payable to Aimco pursuant to those notes is added to the GAAP-based amounts to arrive at the proportionate balance presented.
[3]	Aimco’s internal NAV estimate is computed based on Aimco’s share of NOI and as such takes into account Aimco’s share of NOI attributable to unconsolidated partnerships. For this reason, investment in unconsolidated real estate partnerships is excluded from non-real estate assets in Aimco’s internal NAV computation.
[4]	Deferred financing costs, goodwill and investment in management contracts represent non-tangible assets for which cash has already been paid by Aimco. As such, these amounts are excluded from Aimco’s internal NAV computation.
[5]	Deferred income consists primarily of cash contributions received in connection with Aimco’s tax credit activities, which are deferred upon receipt and amortized into earnings in future periods as the tax credits and related tax benefits are delivered to the tax credit investors. Certain of Aimco’s tax credit arrangements provide for contributions to be made in installments, which contributions are not reflected in Aimco’s consolidated financial statements until such time as the contributions are received. Deferred income, including deferred tax credit income, represents a non-cash obligation, the amortization of which represents non-cash income in future periods. These non-cash liabilities and related income streams are excluded from Aimco’s internal estimates of NAV. However, amortization of deferred tax credit income is included in net income and, as such, FFO. Projected amortization of deferred tax credit contributions received and to be received is presented below.

Total Conventional Portfolio Data by Market
Third Quarter 2010 Market Information
(unaudited)

Aimco’s portfolio strategy focuses on the ownership of a broadly diversified portfolio of B/B+ assets with properties concentrated in the 20 largest U.S. markets as measured by total apartment value, with a target allocation to Conventional Properties of 90%. Aimco measures Conventional Property asset quality based on average rents compared to local market average rents as reported by REIS (a third-party provider of commercial real estate performance and analysis), with A-quality assets earning rents greater than 125% of local market average, B-quality assets earning rents 90% to 125% of local market average and C-quality assets earning rents less than 90% of local market average. Aimco’s geographic allocation strategy focuses on the 20 largest U.S. markets, with market quality measured in part based on long-term growth characteristics.

The following schedule illustrates Aimco’s Conventional Property portfolio quality and market growth projections based on 3Q 2010 data, as this is the most recent period for which third-party data is available.

2010 Acquisitions

During 2010, Aimco acquired the remaining noncontrolling limited partnership interests in two consolidated real estate partnerships in which Aimco affiliates serve as general partner, for total consideration of $19.9 million.

Notes

[1]	NOI Cap Rate is calculated based on the trailing twelve month NOI prior to sale, less a 3.5% management fee, divided by the gross proceeds. Prior to 1Q 2010, Aimco provided a Free Cash Flow cap rate on this schedule, which represented an NOI cap rate assuming a 5% management fee and an adjustment of $300 per door for capital replacements.
[2]	Net Sales Proceeds are after repayment of existing debt, net working capital settlements, payment of transaction costs and prepayment penalties.
[3]	Year-to-date, Aimco has disposed of Conventional Properties in the following markets:

Capital Additions
(in thousands, except per unit data) (unaudited)

All capital additions are classified as either Capital Replacements (“CR”), Capital Improvements (“CI”), Redevelopment or Casualties. Non-redevelopment and non-casualty capital additions are apportioned between CR and CI based on the useful life of the capital item under consideration and the period Aimco has owned the property (i.e., the portion that was consumed during Aimco’s ownership of the item represents CR; the portion of the item that was consumed prior to Aimco’s ownership represents CI). See the Glossary for further descriptions.

Amounts below represent actual additions related to residential properties that are owned and managed by Aimco at the end of the period. These amounts include consolidated and unconsolidated properties and are not adjusted for Aimco’s ownership interest in such properties. Amounts do not include capital additions related to:

• properties sold during the period or properties held for sale at the end of the period;

• properties that are not multi-family such as commercial properties or fitness facilities; and

• properties that Aimco owns but does not manage.

See the Glossary for a reconciliation of these amounts to GAAP capital additions.

Glossary and Reconciliations of Non-GAAP Financial and Operating Measures

This Earnings Release and Supplemental Information include certain financial measures used by Aimco management that are not calculated in accordance with accounting principles generally accepted in the United States, or GAAP. Aimco’s definition and calculation of these non-GAAP financial and operating measures and other terms may differ from the definitions and methodologies used by other REITs and, accordingly, may not be comparable. These non-GAAP financial and operating measures should not be considered an alternative to GAAP net income or any other GAAP measurement of performance and should not be considered an alternative measure of liquidity.

ACQUISITION PROPERTIES:Properties that have been acquired during the twelve months prior to the current quarter-end that have not reached a stabilized level of occupancy during the current period and each period for which comparable results are presented.

ADJUSTED FUNDS FROM OPERATIONS (AFFO):AFFO is Pro forma FFO, as defined below, less Capital Replacement additions, also defined below, and adjusted for the Aimco Operating Partnership’s share of such Capital Replacements. Similar to FFO, AFFO is helpful to investors in understanding Aimco’s 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 depreciating assets such as machinery, computers or other personal property. There can be no assurance that Aimco’s method for computing AFFO is comparable with that of other real estate investment trusts.

AFFORDABLE PROPERTIES:Affordable Properties 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 (HUD) or state housing finance agencies, typically provide mortgage insurance, favorable financing terms, tax credit equity, or rental assistance payments to the property owners. Under these programs, rent adjustments are made in accordance with property-specific contracts between Aimco and HUD, with rent increases generally based on an adjustment factor set by HUD annually. Aimco targets an investment in Affordable Properties of 10% or less of Net Asset Value, which serves to offset the volatility of our Conventional portfolio; provide revenue growth that over time is similar to that of Conventional Properties; expand our investment opportunities; and provide helpful positioning with government bodies, benefiting Aimco’s business overall.

AIMCO OPERATING PARTNERSHIP:AIMCO Properties, L.P., a Delaware limited partnership, is the operating partnership in Aimco’s UPREIT structure. Aimco owns approximately 93% of the common partnership units of the Aimco Operating Partnership.

AIMCO PROPORTIONATE FINANCIAL INFORMATION:Non-GAAP measures representing Aimco’s share of financial information discussed in this Earnings Release and Supplemental Information. Aimco’s proportionate share of financial information includes Aimco’s share of unconsolidated real estate partnerships and excludes noncontrolling interests in consolidated real estate partnerships. Proportionate reporting benefits the users of Aimco’s financial information by providing the amount of revenues, expenses, assets and liabilities attributable only to Aimco stockholders. Aimco also refers to this measure as “Aimco’s Share” of financial information. See Supplemental Schedules 1, 3 and 4 for reconciliation of Aimco’s proportionate share of financial results to Aimco’s consolidated financial statements.

CAPITAL ADDITIONS DEFINITIONS AND RECONCILIATION

CAPITAL IMPROVEMENTS (CI): CI additions include all non-redevelopment capital additions that are made to enhance the value, profitability or useful life of an asset from its original purchase condition.

CAPITAL REPLACEMENTS (CR): Unlike CI additions, CR additions do not increase the useful life of an asset from its original purchase condition. They represent the share of additions that are deemed to replace the consumed portion of acquired capital assets. CR additions are deducted in the calculation of AFFO.

CASUALTY CAPITAL ADDITIONS: Capitalized costs incurred in connection with casualty losses and are associated with the restoration of the asset. A portion of the restoration costs is reimbursed by insurance carriers net of deductibles associated with each loss.

Supplemental Schedule 9 contains capital additions information related to (1) residential properties that Aimco owns and manages at the end of the period, (2) properties that are consolidated in Aimco’s GAAP financial statements, and (3) properties that are accounted for under the equity method of accounting in Aimco’s GAAP financial statements. Amounts do not include capital additions related to:

• consolidated properties sold during the period or properties held for sale at the end of the period;

• consolidated properties that are not multi-family such as commercial properties or fitness facilities; or

• consolidated properties that Aimco owns but does not manage.

Aimco believes the capital addition detail provided in Supplemental Schedule 9 provides an enhanced understanding of capital additions related to our primary business of owning and operating apartment communities. A reconciliation of capital additions presented on Supplemental Schedule 9 to Aimco’s consolidated GAAP information is presented below.

	Three Months Ended			Year Ended

Consolidated properties Aimco owns but does not manage		20			676
Consolidated capital additions	$	46,439		$	175,330

CONVENTIONAL PROPERTIES:Conventional Properties represent Aimco’s portfolio of market-rate apartment communities. Aimco focuses on owning and operating apartment communities with rents that are 100% to 125% of local market average rents and concentrates its investment in the 20 largest apartment markets in the United States, as measured by apartment value. Aimco targets an investment in Conventional Properties of 90% or more of Net Asset Value.

DEBT SERVICE COVERAGE RATIO:As defined in Aimco’s credit agreement, the ratio of (a) Aimco’s adjusted total earnings before interest, taxes, depreciation and amortization (which is reduced by certain capital expenditure reserves) to (b) the actual debt service, for the four fiscal quarters preceding the date of calculation.

EFFECTIVE UNITS:Unit count at 100% ownership multiplied by Aimco’s ownership share. Effective Units may be used to analyze Aimco’s proportionate financial measures on a per-unit basis.

AIMCO 4th Quarter 2010 Page 21

EARNINGS BEFORE INTEREST, TAXES, DEPRECIATION AND AMORTIZATION (EBITDA):EBITDA is equal to Aimco’s adjusted total earnings before interest, taxes, depreciation and amortization as defined in Aimco’s credit agreementbeforecapital addition reserves provided for in Aimco’s credit agreement. EBITDA is the numerator used in Aimco’s calculation of EBITDA Coverage of Interest Ratio and EBITDA Coverage of Preferred Dividends and Interest Ratio.

EBITDA COVERAGE OF INTEREST RATIO:The ratio of (a) Aimco’s EBITDA to (b) total interest expense charges, as provided for in Aimco’s credit agreement, for the four fiscal quarters preceding the date of calculation. This ratio is similar to Aimco’s Debt Service Coverage Ratio with the exception that Aimco’s EBITDA Coverage of Interest Ratio does not include capital addition reserves in the numerator and does not include debt amortization or capitalized interest in the denominator, while Debt Service Coverage Ratio does include these items. Aimco’s credit agreement does not contain any compliance thresholds for the EBITDA Coverage of Interest Ratio; however, Aimco management uses this ratio as one measure of leverage.

EBITDA COVERAGE OF INTEREST AND PREFERRED DIVIDENDS RATIO:The ratio of (a) Aimco’s EBITDA to (b) the sum of total interest expense and dividends/distributions on preferred shares/units, as provided for in Aimco’s credit agreement, for the four fiscal quarters preceding the date of calculation. This ratio is similar to Aimco’s Fixed Charge Coverage Ratio with the exception that Aimco’s EBITDA Coverage of Interest and Preferred Dividends Ratio does not include capital addition reserves in the numerator and does not include debt amortization or capitalized interest in the denominator, while Fixed Charge Coverage Ratio does include these items. Aimco’s credit agreement does not contain any compliance thresholds for the EBITDA Coverage of Interest and Preferred Dividends Ratio; however, Aimco management uses this ratio as one measure of leverage.

FIXED CHARGE COVERAGE RATIO:As defined in Aimco’s credit agreement, the ratio of (a) Aimco’s adjusted total earnings before interest, taxes, depreciation and amortization (which is reduced by certain capital expenditure reserves) to (b) fixed charges, which represents the sum of total interest expense, debt amortization and dividends/distributions on preferred shares/units, for the four fiscal quarters preceding the date of calculation.

FEE MANAGED PROPERTIES:Aimco provides property management and/or asset management services for a portfolio of properties, primarily pursuant to long-term arrangements with affiliated parties. In certain cases, Aimco may indirectly own generally less than one percent of the operations of such properties through a partnership syndication or other fund.

FUNDS FROM OPERATIONS (FFO):FFO is a commonly used measure of REIT performance, which the National Association of Real Estate Investment Trusts (NAREIT) defines as net income, 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. Aimco computes FFO for all periods presented in accordance with the guidance set forth by NAREIT’s April 1, 2002 White Paper.

In addition to FFO, Aimco usesPRO FORMA FUNDS FROM OPERATIONS (Pro forma FFO)to measure performance. Pro forma FFO represents FFO as defined above, excluding operating real estate impairments and preferred stock redemption related amounts (adjusted for noncontrolling interests). Both operating real estate impairment losses and preferred stock redemption related amounts are recurring items that affect Aimco’s operating results. Operating real estate impairment losses, net of related income tax benefits and noncontrolling interests, are excluded from Pro forma FFO because Aimco believes the inclusion of such losses in FFO is inconsistent with the treatment of gains on the disposition of operating real estate, which are not included in FFO. Aimco excludes preferred redemption related amounts (gains or losses) from Pro forma FFO because such amounts are not representative of operating results.

AIMCO 4th Quarter 2010 Page 22

FFO and Pro forma FFO are helpful to investors in understanding Aimco’s performance because they capture 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 depreciating assets such as machinery, computers or other personal property. There can be no assurance that Aimco’s method for computing FFO is comparable with that of other real estate investment trusts. Net income (loss) attributable to Aimco common stockholders as determined in accordance with GAAP is reconciled to FFO and Pro forma FFO as presented on Supplemental Schedule 1 below.

AIMCO 4th Quarter 2010 Page 23

PROPERTY NET OPERATING INCOME (NOI):NOI is defined by Aimco as total property rental and other property revenues less direct property operating expenses, including real estate taxes. NOI does not include: property management revenues, primarily from affiliates; casualties; off-site property management expenses; depreciation; or interest expense. NOI is helpful because it helps both investors and management to understand the operating performance of real estate excluding costs associated with decisions about acquisition pricing, overhead allocations and financing arrangements. NOI is considered by many in the real estate industry to be a useful measure for determining the value of real estate. A reconciliation of NOI as presented in this Earnings Release and Supplemental Information to Aimco’s consolidated GAAP amounts is provided below and on the following pages.

REDEVELOPMENT PROPERTIES:Properties where (1) a substantial number of available units have been vacated for major renovations or have not been stabilized in occupancy for at least one year as of the earliest period presented, or (2) other significant renovation, such as exteriors, common areas or unit improvements (done upon lease expirations), is underway or has been complete for less than one year, as of the earliest period presented. In both cases the properties have been removed from the Same Store portfolio. Redevelopment properties are classified as either Conventional or Affordable. Aimco combines Affordable Redevelopment Properties with Other Affordable Properties for financial reporting purposes within its Supplemental Schedules 1 and 2.

SAME STORE PROPERTIES: Same Store properties are those properties (1) that are managed by Aimco, (2) in which Aimco’s ownership exceeds 10%, and (3) that have reached and maintained a stabilized level of occupancy during the current period and each period for which comparable results are presented. Same Store properties are classified as either Conventional or Affordable and properties classified in the consolidated financial statements as held for sale are not included in Same Store. To ensure comparability between periods, the proportionate Conventional Same Store information shown on Supplemental Schedules 6a through 6c is based on Aimco’s current period ownership.
