Aimco Reports Fourth Quarter 2012 Results

Denver, Colorado, February 7, 2013 - Apartment Investment and Management Company (“Aimco”) (NYSE: AIV) announced today its fourth quarter 2012 results.

Chairman and Chief Executive Officer Terry Considine comments: “Aimco had a solid 2012. Profitability is up with Conventional Same Store NOI growth of 6.5%, the highest rate of annual growth in six years. Portfolio quality is also up with average revenue per unit in our Conventional portfolio increasing nearly 8% to $1,362. Redevelopment investment tripled to $100 million. But, leverage is down: the ratio of Debt plus Preferred Equity to annualized fourth quarter EBITDA declined by about two times from 9.6 times to 7.7 times.”

Considine adds: “We look for 2013 to be another good year with increasing profitability in operations, disciplined upgrading of our portfolio, increased investment in redevelopment, lower leverage, and further simplification leading to lower offsite costs.”

Adjusted Funds From Operations (AFFO)	$	0.38		$	0.20		$	1.34		$	0.87

* Full year 2011 financial results include a deduction of $0.15 per share related to debt prepayment penalties and the write-off of deferred loan costs incurred in connection with a refinancing and securitization transaction during second quarter 2011. Excluding these charges, comparable full year 2011 Pro forma FFO and AFFO per share were $1.64 and $1.02, respectively. On this comparable basis, full year 2012 Pro forma FFO and AFFO increased 12% and 31%, respectively, compared to 2011.

Pro forma FFO - Pro forma FFO increased 24% when compared to fourth quarter 2011 as a result of: improved property operating results; additional income from increased ownership in our consolidated properties; lower preferred stock dividends due to $600.9 million of redemptions during 2012; and lower interest expense. These positive results were somewhat offset by lower income from discontinued operations. Pro forma FFO was $0.02 per share above the midpoint of Aimco's guidance range of $0.47 to $0.53 per share.

Adjusted Funds from Operations - AFFO increased 90% when compared to fourth quarter 2011 as a result of Pro forma FFO growth, the timing of Capital Replacements spending during 2012, and lower Capital Replacements spending due to the sale of nearly 11,000 apartment units during 2012. As Aimco's portfolio is concentrated in fewer properties with higher margins, AFFO is expected to grow at a faster rate than Pro forma FFO growth.

Property Operations

Aimco's property operations consist primarily of Conventional real estate operations, which relate to Aimco's diversified portfolio of market-rate apartment communities. Aimco also operates a portfolio of Affordable Properties, which consists of properties with rents that are generally paid, in whole or in part, by a government agency. Over the next four to five years, Aimco expects to dispose of these Affordable Properties and reinvest capital in its Conventional portfolio.

Affordable Same Store Results - For fourth quarter 2012, average daily occupancy for the Affordable portfolio was 98.9%, an increase of 1.2% from fourth quarter 2011, while average revenue per unit increased 1.1% from $970 to $981 per unit.

Portfolio Management

Aimco's portfolio strategy seeks predictable rent growth from a portfolio of A, B and C-quality conventional properties, averaging B/B+ in quality, and diversified among the largest coastal and job growth markets in the U.S., as measured by total apartment value.

Aimco measures Conventional Property asset quality based on 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 asset quality as follows: A-quality assets are those with rents greater than 125% of local market average; B-quality assets are those with rents 90% to 125% of local market average; and C-quality assets are those with rents less than 90% of local market average. For third quarter 2012, the most recent period for which REIS information is available, Aimco's Conventional Property rents averaged 102% of local market average rents.

Aimco's target markets are primarily coastal markets, and also include several Sun Belt cities and Chicago, Illinois. In executing its portfolio strategy, Aimco expects to sell each year the lowest-rated 5% to 10% of its portfolio and to invest the proceeds from such sales in redevelopment and acquisition of higher-quality properties. Through this disciplined approach to capital recycling, from 2007 through 2012, Aimco increased its year-end conventional portfolio average revenue per unit at a compound annual growth rate of 6.1%, about three times that of market rent growth during the same period. Aimco's outsized growth reflects the impact of portfolio improvements through dispositions, redevelopment and acquisitions.

Conventional Property Revenue per Unit Up 7.9% to $1,362

Fourth quarter 2012 Conventional portfolio average revenue per unit was $1,362, an 7.9% increase compared to fourth quarter 2011, as a result of year-over-year revenue growth of 5.1% and the sale of Conventional Properties during 2011 and 2012 with average revenues per unit substantially lower than those of the retained portfolio.

Dispositions - In fourth quarter 2012, Aimco sold eight Conventional Properties and 16 Affordable Properties with 1,865 and 1,417 units, respectively, for $271.1 million in gross proceeds. Average revenue per unit for the Conventional Properties sold during the quarter was $1,087, compared to the retained portfolio average of $1,362 per unit. Aimco's share of net sales proceeds after distributions to limited partners, repayment of existing property debt and transaction costs was $123.7 million.

Sale of Asset-Management Business - During the fourth quarter, Aimco closed on the sale of the NAPICO portfolio, its legacy asset management business.  The transaction was primarily seller financed, and the associated notes will be repaid over the next six years. Aimco anticipates recognizing between $6 and $8 million in Funds from Operations over the expected term of the notes.

Redevelopment

During the fourth quarter, Aimco began multi-phase capital projects at Park Towne Place and The Sterling, both located in Center-City Philadelphia. The initial phases of these projects consist of Capital Replacement and Capital Improvement investments, with redevelopment to follow.

Leverage Ratios

Aimco's leverage targets are: Debt and Preferred Equity to EBITDA of less than 7.0x; and EBITDA Coverage of Interest and Preferred Dividends of greater than 2.5x. Aimco also focuses on Debt to EBITDA and EBITDA Coverage of Interest ratios. See the Glossary for definitions of these metrics.

	Trailing- Twelve- Month		Annualized 4th Qtr
	2012	2011	2012	2011
Debt to EBITDA	7.5x	8.2x	7.4x	8.2x
Debt and Preferred Equity to EBITDA	7.8x	9.5x	7.7x	9.6x
EBITDA Coverage of Interest	2.3x	2.1x	2.5x	2.2x
EBITDA Coverage of Interest and Preferred Dividends	2.2x	1.8x	2.4x	1.8x

EBITDA Coverage of Interest and Preferred Dividends ratios are provided on a pro forma basis to exclude dividends on preferred stock redeemed during 2012.

Future leverage reduction is expected from earnings growth generated by the current portfolio and by regularly scheduled property debt amortization funded from retained earnings.

Liquidity

Aimco's recourse debt at December 31, 2012, was limited to its revolving credit facility, which Aimco uses for working capital purposes and to secure letters of credit. Borrowings bear interest at a rate set forth on a pricing grid which rate varies based on Aimco's leverage. The revolving credit facility matures in December 2014, and may be extended for two additional one-year periods, subject to certain conditions.

At the end of fourth quarter, Aimco had no outstanding borrowings on its revolving credit facility and available capacity was $454.6 million, net of $45.4 million of letters of credit backed by the facility. Also at the end of the quarter, Aimco had on hand $84.4 million of cash.

Equity Activity

Dividend - As announced on January 31, 2013, Aimco's Board of Directors declared a quarterly cash dividend of $0.24 per share of Class A Common Stock for the quarter ended December 31, 2012, which, on an annualized basis, is a 26% increase compared to the dividends paid during 2012. The fourth quarter 2012 dividend is payable on February 28, 2013, to stockholders of record on February 15, 2013.

Notes to 2013 Outlook and 2013 Pro forma FFO Reconciliation

[1] Property upgrades may include kitchen and bath remodeling; energy conservation projects; and investments in longer-lived materials designed to reduce turnover costs, such as simulated wood flooring and granite countertops.

[2] During 2012, Aimco began multi-phase capital projects at its 2900 on First property, located in Seattle, and two Center-City Philadelphia properties, Park Towne Place and The Sterling. The initial phases of these projects consist of Capital Replacement and Capital Improvement investments, which totaled $4.1 million in 2012. Aimco expects to invest an additional $17 million in Capital Replacements related to these projects during 2013.

[3] Partnership transactions are expected to close during the first half of 2013.

[4] During 2013, Aimco intends to dispose of that portion of its Affordable portfolio not subject to tax credit agreements. If successful, Aimco will hold at the end of the year 53 Affordable properties with approximately 8,000 units, which were redeveloped with Low Income Housing Tax Credits, generally between 2005 and 2009. These properties are expected to be sold as the tax credit compliance periods expire with the majority of sales expected to occur from 2015 to 2019.

[5] Aimco intends to use proceeds from asset sales to fund real estate investments including redevelopment and other capital investments, and partnership transactions.

[6] Anticipated size of unencumbered pool at December 31, 2013, based on December 31, 2012, values.

[7] Aimco's casualty losses during 2012 were significantly lower than the company's historical average, largely due to fewer weather-related casualty events. Aimco's Pro forma FFO guidance assumes 2013 loss experience returns to historical levels.

Forward-looking Statements

This Earnings Release and Supplemental Information contain forward-looking statements within the meaning of the federal securities laws, including, without limitation, statements regarding projected results and specifically forecasts of: first quarter and full year 2013 results, including but not limited to Pro forma FFO and selected components thereof, Capital Replacements spending, and AFFO; redevelopment project investments, timelines and stabilized rents; and timing of other investment activity. These forward-looking statements are based on management's judgment as of this date and include certain risks and uncertainties. Risks and uncertainties include, but are not limited to: Aimco's ability to maintain current or meet projected occupancy, rental rates and property operating results; the effect of acquisitions, dispositions and redevelopments; and our ability to comply with debt covenants, including financial coverage ratios. 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 the control of Aimco, including, without limitation: financing risks, including the availability and cost of capital markets 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, including the pace of job growth and the level of unemployment; the terms of governmental regulations that affect Aimco and interpretations of those regulations; the competitive environment in which Aimco operates; the timing of acquisitions, dispositions and redevelopments; 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 Aimco. In addition, our 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 Aimco's financial statements and the notes thereto, as well as the section entitled “Risk Factors” in Item 1A of Aimco's Annual Report on Form 10-K for the year ended December 31, 2011, and the other documents Aimco files from time to time with the Securities and Exchange Commission. These forward-looking statements reflect management's judgment as of this date, and Aimco assumes no obligation to revise or update them to reflect future events or circumstances. This press release does not constitute an offer of securities for sale.

[1]	Refer to the Glossary for the definition of Proportionate Property Net Operating Income, as well as a reconciliation of the trailing twelve month amounts of Rental and other property revenues, Property operating expenses and Proportionate Property Net Operating Income to the corresponding amounts computed in accordance with GAAP.
[2]	Net real estate includes three substantially vacant redevelopment properties, Lincoln Place, Pacific Bay Vistas and The Preserve at Marin, that have December 31, 2012, net book values of $328 million in total. These properties are included in Aimco’s redevelopment pipeline.
[3]	Deferred income includes $81.8 million of unamortized cash contributions received by Aimco in exchange for the sale of tax credit and related tax benefits. These cash contributions are deferred upon receipt and amortized into earnings in future periods as Aimco delivers the tax credits and related benefits to the investors.
	Deferred income and the future earnings associated with the deferred income 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, as well as the estimated income taxes thereon, are presented below.

Total Conventional Portfolio Data by Market
Third Quarter 2012 Market Information
(unaudited)
Aimco's portfolio strategy seeks predictable rent growth from a portfolio of A, B and C-quality conventional properties, averaging B/B+ in quality, and diversified among the largest coastal and job growth markets in the U.S. as measured by total apartment value. Aimco measures Conventional Property asset quality based on 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 asset quality as follows: A-quality assets are those with rents greater than 125% of local market average; B-quality assets are those with rents 90% to 125% of local market average; and C-quality assets are those with rents less than 90% of local market average. The following schedule illustrates Aimco’s Conventional Property portfolio quality and market growth projections based on 3Q 2012 data, the most recent period for which third-party data is available.

[2] NOI Cap Rate is calculated based on Aimco's share of the trailing twelve month NOI prior to sale, less a 3.0% management fee, divided by the gross proceeds, which excludes prepayment penalties associated with the related property debt.
[3] Net Sales Proceeds are after repayment of existing debt, net working capital settlements, payment of transaction costs and debt prepayment penalties.
[4] Non-recourse property debt assumed in connection with acquisition.

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 over which 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 operations or fitness facilities at Aimco's multi-family properties; 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 definitions and calculations 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 acquired since January 1, 2011.

ADJUSTED INTEREST EXPENSE: Adjusted Interest Expense represents Aimco's proportionate share of interest expense less (i) prepayment penalties and amortization of deferred financing costs and (ii) the amount of interest income recognized by Aimco related to its investment in the subordinated tranches in a securitization trust holding only Aimco property debt.

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 OPERATING PARTNERSHIP:AIMCO Properties, L.P., a Delaware limited partnership, is the operating partnership in Aimco's UPREIT structure. Aimco owns approximately 95% 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 includes 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, CR does not increase the useful life of an asset from its original purchase condition. CR represents the portion of capital additions that are deemed to replace the consumed portion of acquired capital assets. CR is deducted in the calculation of AFFO.

CASUALTY CAPITAL ADDITIONS: Casualty capital additions represent capitalized costs incurred in connection with the restoration of an asset after a casualty event such as a hurricane, tornado or flood.

32

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 classified as 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.

(in thousands) (unaudited)	Quarter Ended December 31, 2012			Year Ended December 31, 2012
Capital Additions per Schedule 9	$	85,955		$	260,043
Capital additions related to:
Unconsolidated real estate partnerships	(140		)	(1,226		)
Consolidated sold and held for sale properties	249			12,142
Consolidated properties Aimco owns but does not manage	127			821
Consolidated properties that are not multi-family, such as commercial properties or fitness facilities	147			323
Consolidated capital additions	$	86,338		$	272,103

CONVENTIONAL PROPERTIES: Conventional Properties represent Aimco's portfolio of market-rate apartment communities. Aimco's portfolio strategy seeks predictable rent growth from a portfolio of A, B and C-quality conventional properties, averaging B/B+ in quality, and diversified among the largest coastal and job growth markets in the United States, as measured by apartment value.

DEBT TO EBITDA RATIO: The ratio of (a) Aimco's proportionate share of debt net of Aimco's proportionate share of cash and restricted cash, and Aimco's investment in the subordinated tranches in a securitization trust holding only Aimco property debt to (b) EBITDA.

DEBT AND PREFERRED EQUITY TO EBITDA RATIO: The ratio of (a) Aimco's proportionate share of debt net of Aimco's proportionate share of cash and restricted cash, and Aimco's investment in the subordinated tranches in a securitization trust holding only Aimco property debt, plus Aimco's preferred stock and the preferred units of the Aimco Operating Partnership to (b) EBITDA.

DEBT SERVICE COVERAGE RATIO: As defined in Aimco's credit agreement, the ratio of (a) Earnings Before Interest, Taxes, Depreciation and Amortization (Compliance EBITDA), reduced by certain capital expenditure reserves, to (b) debt service, which represents the sum of (i) Aimco's proportionate share of interest expense (excluding prepayment penalties and amortization of deferred financing costs) and (ii) debt amortization, for the four fiscal quarters preceding the date of calculation.

EFFECTIVE UNITS: The number of actual property units multiplied by Aimco's ownership interest in the property as of the end of the current period. Effective Units may be used to analyze Aimco's proportionate financial measures on a per-unit basis.

33

EARNINGS BEFORE INTEREST, TAXES, DEPRECIATION AND AMORTIZATION (EBITDA): 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 is computed by adding to Aimco's Pro forma FFO (a) Aimco's proportionate share of interest expense, taxes, depreciation and amortization related to non-real estate assets, non-cash stock compensation expense and (b) Preferred Dividends.

EBITDA COVERAGE OF INTEREST RATIO: The ratio of (a) EBITDA to (b) Adjusted Interest Expense. Aimco's management uses this ratio as one measure of leverage.

EBITDA COVERAGE OF INTEREST AND PREFERRED DIVIDENDS RATIO: The ratio of (a) EBITDA to (b) the sum of Adjusted Interest Expense and Preferred Dividends. Aimco's management uses this ratio as one measure of leverage.

FIXED CHARGE COVERAGE RATIO: As defined by Aimco's credit agreement, the ratio of (a) EBITDA computed in accordance with the terms of Aimco's credit agreement, which differs from EBITDA defined above, to (b) fixed charges, which represent the sum of (i) Aimco's proportionate share of interest expense (excluding prepayment penalties and amortization of deferred financing costs), (ii) debt amortization and (iii) Preferred Dividends, for the four fiscal quarters preceding the date of calculation.

FREE CASH FLOW INTERNAL RATE OF RETURN: Free Cash Flow represents a property's net operating income less capital spending required to maintain the condition of the property, and a Free Cash Flow Internal Rate of Return represents the rate of return generated by discounting the expected Free Cash Flow from the property and the proceeds from its eventual sale.

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, and impairment losses recognized with respect to, 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.

In addition to FFO, Aimco uses PRO FORMA FUNDS FROM OPERATIONS (Pro forma FFO) and ADJUSTED FUNDS FROM OPERATIONS (AFFO)to measure performance. Pro forma FFO represents FFO as defined above, excluding preferred equity redemption related amounts (adjusted for noncontrolling interests). Preferred equity redemption related amounts (gains or losses) are items that periodically affect Aimco's operating results. Aimco excludes preferred equity redemption related amounts (gains or losses) from Pro forma FFO because such amounts are not representative of operating performance. AFFO represents Pro forma FFO reduced by Capital Replacements (also adjusted for noncontrolling interests).

FFO, Pro forma FFO and AFFO 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, Pro forma FFO or AFFO 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 and reconciled to AFFO on the following page.

NEW LEASE AND RENEWAL RATES: Aimco measures changes in rental rates by comparing, on a lease-by-lease basis, the rate on a newly executed lease to the rate on the expiring lease for that same apartment. Newly executed leases are classified as either a new lease, where a vacant apartment is leased to a new customer, or a renewal of an existing lease.

OTHER AFFORDABLE PROPERTIES: Affordable Properties that do not meet the Same Store Property definition because they are not managed by Aimco and/or Aimco's ownership interest is less than 10%.

OTHER CONVENTIONAL PROPERTIES: Conventional Properties that have significant rent control restrictions, non-multi-family such as commercial operations or fitness facilities at Aimco's multi-family properties, and properties that had not reached and maintained a stabilized level of occupancy as of January 1, 2011, often due to a casualty event.

35

OTHER EXPENSES, NET: Other expenses, net includes franchise taxes, risk management activities related to our unconsolidated partnerships, certain other corporate expenses and partnership expenses (partnership level expenses incurred directly or indirectly for services such as audit, tax and legal).

PREFERRED DIVIDENDS: Preferred dividends include dividends paid with respect to Aimco's Preferred Stock and the Aimco Operating Partnership Preferred Partnership Units.

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; 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 page.
