Aimco Reports Third Quarter 2013 Results

Denver, Colorado, October 31, 2013 - Apartment Investment and Management Company (“Aimco”) (NYSE: AIV) announced today its third quarter 2013 results.

Chairman and Chief Executive Officer Terry Considine comments: "Aimco enjoyed a solid third quarter. Business is good with steady demand driving higher rents. Our portfolio gets better and better as we add high quality properties through redevelopment, acquisitions and selective development funded by the sale of lower-rated properties."

Chief Financial Officer Ernie Freedman adds: "Pro forma FFO of $0.50 per share was equal to the midpoint of our guidance. We are projecting fourth quarter Pro forma FFO to be in a range from $0.53 to $0.59."

Pro forma FFO Up 11%, AFFO Up 15% Year-to-Date

	THIRD QUARTER						YEAR-TO-DATE
(all items per common share)	2013			2012			2013			2012
Net income	$	0.46		$	0.17		$	0.56		$	0.11
Funds from Operations (FFO)	$	0.50		$	0.38		$	1.47		$	1.15

Pro forma Funds from Operations (Pro forma FFO)	$	0.50		$	0.46		$	1.47		$	1.32
Deduct Aimco's share of Capital Replacements	$	(0.15	)	$	(0.13	)	$	(0.37	)	$	(0.36	)
Adjusted Funds From Operations (AFFO)	$	0.35		$	0.33		$	1.10		$	0.96

Pro forma FFO - Pro forma FFO increased 9% when compared to third quarter 2012, as a result of improved property operating results, lower offsite costs, additional interest income earned on the West Harlem property loans acquired in second quarter 2013, and lower interest expense due to refinancing activities. These positive results were somewhat offset by lower investment management income and lower income from discontinued operations.

Adjusted Funds from Operations - AFFO increased 6% when compared to third quarter 2012, as a result of Pro forma FFO growth, offset somewhat by increased Capital Replacement spending. An increase in 2013 Capital Replacement spending related to multi-phase capital projects was partially offset by a reduction in Standard Capital Replacements due to the sale of approximately 11,000 apartment homes during 2012. As Aimco concentrates its investment capital in higher quality, higher price-point properties, Capital Replacements decline as a percentage of net operating income. As a result, AFFO, up 15% year-to-date, is increasing at a faster rate than is Pro forma FFO, up 11% year-to-date.

Property Operations

Aimco's property operations consist primarily of 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 proceeds in its Conventional portfolio.

Year-Over-Year Conventional Same Store NOI Up 5.9%

Rental 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.

2013	1st Qtr	2nd Qtr	Jul	Aug	Sep	3rd Qtr	Year-to-Date Sep	Preliminary Oct
Renewal rent increases	5.3%	5.2%	5.1%	5.0%	5.3%	5.1%	5.2%	4.5%
New lease rent increases	2.6%	3.1%	3.6%	2.9%	(1.3)%	1.7%	2.3%	1.1%
Weighted average rent increases	3.9%	4.1%	4.3%	3.9%	1.6%	3.3%	3.7%	3.1%

In September, Aimco executed a targeted "sale" in Greater Washington D.C. and in Philadelphia in order to increase occupancy in advance of the expected seasonal slowdown in consumer demand. Concessions that were offered at these properties to build occupancy were largely eliminated at the end of September. On a preliminary basis, October new lease rates increased 1.1% across Aimco's entire Same Store portfolio. This result compares favorably to new lease rate increases in September 2013, and to new lease rate increases of 0.4% in October 2012.

Affordable Same Store Results - For third quarter 2013, average daily occupancy for the Affordable portfolio was 98.9%, which was consistent with third quarter 2012, while average revenue per apartment home increased 1.1% from $969 to $980 per apartment home.

Portfolio Management

Aimco's portfolio strategy seeks predictable rent growth from a portfolio of "A", "B" and "C" quality market-rate 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's target markets are primarily coastal markets, and also include several Sun Belt cities and Chicago, Illinois.

Aimco measures 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 lower than 90% of local market average. For second quarter 2013, the most recent period for which REIS information is available, Aimco's Conventional Property rents averaged 103% of local market average rents.

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 apartment home at a compound annual growth rate of 6.1%, approximately three times the growth rate of market rents. This outsized rate of growth reflects the impact of portfolio management through dispositions, redevelopment and acquisitions.

Conventional Property Revenue Per Apartment Home Up 6.6% to $1,426

Third quarter 2013 Conventional portfolio average revenue per apartment home was $1,426, a 6.6% increase compared to third quarter 2012, as a result of year-over-year revenue per apartment home growth of 4.4% and the sale of Conventional Properties during 2012 and 2013 with average revenues per apartment home substantially lower than those of the retained portfolio.

Portfolio Management Activities

Dispositions - In third quarter 2013, Aimco sold five Conventional Properties and three Affordable Properties with 1,959 and 321 apartment homes, respectively, for $166.9 million in gross proceeds. Aimco's share of net sales proceeds after distributions to limited partners, repayment of existing property debt and transaction costs was $57.2 million. The wind down of Aimco’s Affordable portfolio continued from more than 250 properties three years ago to 79 properties at the end of third quarter 2013.

Acquisitions - As previously announced, Aimco acquired two properties during the third quarter. Aimco acquired for $9.5 million a five-story building located in Midtown Atlanta adjacent to the 190-acre Piedmont Park and approximately three miles from Aimco's Peachtree Park property. Constructed in 2012, the building consists of 30 apartment homes and approximately 3,700 square feet of retail space. The property's average revenue per apartment home is approximately $2,100, and its rents are 165% greater than the Atlanta market average, making this an "A" quality asset in Aimco's portfolio. Aimco intends to add value to the property through operational improvements.

At closing, the Atlanta acquisition was funded from Aimco's credit facility, which Aimco expects to repay with proceeds from the sale of a property containing 156 apartment homes located in Virginia with average revenue per apartment home of $875. Aimco expects the Free Cash Flow Internal Rate of Return generated by the acquired property to be approximately 100 basis points greater than expected from the property to be sold.

3

Also during the third quarter, Aimco acquired for $15.1 million a 44-apartment home community located in Boston, Massachusetts. Constructed in 2012, the property’s average revenue per apartment home is $2,200 per month, and its rents are 19% greater than the Boston market average, making this a “B+” quality asset in Aimco’s portfolio. At closing, the acquisition was funded from Aimco’s credit facility, which Aimco expects to repay with proceeds from the sale of a Florida property containing 262 apartment homes with average revenue per apartment home of $750. Aimco expects the Free Cash Flow Internal Rate of Return generated by the acquired property to be approximately 150 basis points greater than property expected to be sold.

Redevelopment and Development

During the third quarter, Aimco continued the redevelopment of five properties that began during 2012. In addition, Aimco continued multi-phase capital projects at Park Towne Place and The Sterling, both located in Center City Philadelphia, and 2900 on First, located in Seattle. The initial phases of these projects consist of Capital Replacement and Capital Improvement investments, with redevelopment expected to follow.

As previously announced, during third quarter, Aimco entered into an agreement with Trinity Financial to develop a 12-story building at One Canal Street in the historic Bulfinch Triangle neighborhood of Boston’s West End. Under the terms of the agreement, Trinity and its experienced development team will be responsible for construction of the building.

Over the next two and one-half years, Aimco expects to invest approximately $190 million in the development of One Canal Street, which will include 310 luxury apartment homes, approximately 22,000 square feet of commercial space and 147 parking spaces. The site has been leased to Aimco pursuant to a 99-year ground lease from the Massachusetts Department of Transportation.

The development will be funded in part by a $114 million construction loan and in part by proceeds from the sales of lower-rated properties in less desirable submarkets. The property loan bears interest at a rate of 5.2%, and matures in 2023. Consistent with Aimco’s discipline of upgrading its portfolio through paired-property, leverage-neutral transactions, Aimco has identified four properties with approximately 3,100 apartment homes that Aimco has sold or plans to sell to fund the equity portion of the One Canal Street development. These lower-rated properties are located in Colorado, Indiana, Massachusetts and Texas and have monthly revenues per unit averaging approximately $750. Aimco expects its One Canal Street investment to generate a Free Cash Flow Internal Rate of Return that is 400 to 450 basis points greater than the properties identified for sale and 200 to 225 basis points greater than is available on the acquisition of a comparable, stabilized property in this submarket.

Leverage Ratios

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

	2013		2012
	Trailing-Twelve-Month	Annualized 3rd Qtr	Trailing-Twelve-Month	Annualized 3rd Qtr
Debt to EBITDA	7.8x	7.7x	7.9x	7.7x
Debt and Preferred Equity to EBITDA	8.0x	8.0x	8.1x	8.0x
EBITDA Coverage of Interest	2.5x	2.5x	2.3x	2.3x
EBITDA Coverage of Interest and Preferred Dividends	2.4x	2.4x	1.9x	2.2x

Trailing-twelve-month 2013 Debt to EBITDA and Debt and Preferred Equity to EBITDA ratios are provided on a pro forma basis, taking into account the interest income associated with the West Harlem property loans acquired during the second quarter, which acquisition was funded from Aimco's revolving line of credit.

Aimco continues to expect to achieve its leverage target of Debt and Preferred Equity to EBITDA of approximately 7.0x in the first quarter 2014. Future leverage reduction is expected from earnings growth generated by the current portfolio, by regularly scheduled property debt amortization funded from retained earnings, and by collection of the maturing West Harlem property loans.

Liquidity

Aimco's recourse debt at September 30, 2013, was limited to its revolving credit facility, which Aimco uses for working capital and other short-term purposes, and to secure letters of credit.

As previously announced, during the third quarter, Aimco closed on a new $600 million revolving credit facility to replace its existing $500 million facility. Similar to the facility being replaced, borrowings on the new facility bear interest at a rate set forth on a pricing grid, which varies based on Aimco's leverage. The interest rate spread on the new facility is, on average, 70 basis points lower than the facility being replaced. The new facility matures in September 2018, inclusive of a one-year extension.

At the end of the third quarter, Aimco had outstanding borrowings on its revolving credit facility of $298.6 million and available capacity was $255.6 million, net of $45.8 million of letters of credit backed by the facility. Of the outstanding borrowings, $119.1 million related to the second quarter purchase of the West Harlem property loans. Aimco expects to repay borrowings on its revolving credit facility upon collection of the outstanding property loans and with proceeds from paired-property sales. At the end of the third quarter, Aimco's share of cash and restricted cash on hand was $183.3 million. In addition, Aimco holds four properties in its unencumbered asset pool with a total estimated fair value of approximately $190 million.

Equity Activity

Dividend - As previously announced, Aimco's Board of Directors declared a quarterly cash dividend of $0.24 per share of Class A Common Stock for the quarter ended September 30, 2013. The third quarter 2013 dividend is payable on November 29, 2013, to stockholders of record on November 15, 2013.

Notes to 2013 Outlook

[1] At the midpoint of Aimco's guidance range, AFFO guidance has been reduced by $0.01 per share. This projected reduction in AFFO is due to the planned acceleration of Capital Replacements spending related to multi-phase capital projects. During 2012, Aimco began these 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 $25 million in Capital Replacements related to these projects during 2013. This is an increase of $2 million compared to previous expectations as these projects are ahead of schedule. Total estimated costs are on budget.

[2] At the midpoint of Aimco's guidance ranges, full year 2013 investments in redevelopment and development have been increased by $35 million, due in part to the One Canal Street development project and in part to additional costs related to Aimco's Lincoln Place and Preserve at Marin redevelopment properties.

[3] Aimco has increased its dispositions guidance to reflect acceleration of 2014 sales into 2013, to fund the equity component of its increased investment activity.

[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 in this table to the corresponding amounts computed in accordance with GAAP.
[2]	Net real estate includes three properties, Lincoln Place, Pacific Bay Vistas and The Preserve at Marin, which are vacant or have low occupancies while the properties undergo significant redevelopment. Refer to Supplemental Schedule 10 for further information about these redevelopment projects.
[3]	Deferred income includes $65.8 million of unamortized cash contributions received by Aimco in exchange for the allocation of tax credits and related tax benefits to the investors in tax credit arrangements. 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.
	Under existing tax credit agreements, Aimco will receive additional cash contributions of $37.9 million, which when received will be deferred and amortized into earnings in future periods. Projected amortization of deferred tax credit contributions received and to be received, as well as the estimated income taxes thereon, are presented below. Deferred income and the future earnings associated with the deferred income are excluded from Aimco’s internal estimates of NAV.

Total Conventional Portfolio Data by Market
Second Quarter 2013 Market Information
(unaudited)
Aimco's portfolio strategy seeks predictable rent growth from a portfolio of "A," "B" and "C" quality market-rate 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 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 2Q 2013 data, the most recent period for which third-party data is available.

Supplemental Schedule 9
Capital Additions
(in thousands, except per apartment home data) (unaudited)
Capital additions are classified as either Capital Replacements (“CR”), which includes Standard CR and CR related to multi-phase projects, Property Upgrades, Capital Improvements (“CI”), Redevelopment or Casualty. 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).

GLOSSARY AND RECONCILIATIONS OF NON-GAAP FINANCIAL AND OPERATING MEASURES

This Earnings Release and Supplemental Information include certain financial and operating 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, 2012.

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. Aimco distinguishes CR between those relating to multi-phase capital projects and all other CR, which is referred to as Standard CR.

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.

PROPERTY UPGRADES: 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. Property Upgrades differ from Redevelopment Additions in that they are generally lesser in scope and do not significantly disrupt operations.

REDEVELOPMENT ADDITIONS: Redevelopment represents capital additions intended to enhance the value of property through the ability to generate higher average rental rates. Redevelopment additions may include costs related to entitlement, which enhance the value of a property through increased density, and costs related to renovation of exteriors, common areas or apartment homes.

31

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)	Three Months Ended September 30, 2013		Nine Months Ended September 30, 2013
Capital Additions per Schedule 9	$	110,609	$	263,198
Capital additions related to:
Consolidated sold and held for sale properties	498		1,576
Consolidated properties Aimco does not manage and properties that are not multi-family, such as commercial properties or fitness facilities	39		244
Consolidated capital additions	$	111,146	$	265,018

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 RATIO DEFINITIONS

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.

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) Proportionate 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) Proportionate EBITDA.

DEBT SERVICE COVERAGE RATIO: As defined in Aimco's credit agreement, the ratio of (a) Earnings Before Interest, Taxes, Depreciation and Amortization, reduced by certain capital expenditure reserves (which we refer to as "Compliance EBITDA"), 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.

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

32

EBITDA COVERAGE OF INTEREST AND PREFERRED DIVIDENDS RATIO: The ratio of (a) Proportionate 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) Compliance EBITDA 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.

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

PROPORTIONATE EARNINGS BEFORE INTEREST, TAXES, DEPRECIATION AND AMORTIZATION (PROPORTIONATE EBITDA): Proportionate 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.

EFFECTIVE APARTMENT HOMES: The number of actual apartment homes multiplied by Aimco's ownership interest in the property as of the end of the current period. Effective Apartment Homes may be used to analyze Aimco's proportionate financial measures on a per-home basis.

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% and/or they are not subject to tax credit agreements.

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, 2012, often due to a casualty event.

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).

34

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.
