NOTE 1 -- ORGANIZATION
 
     Apartment Investment and Management Company, a Maryland corporation
incorporated on January 10, 1994 ("AIMCO" and, together with its subsidiaries
and other controlled entities, the "Company"), owns a majority of the ownership
interests in AIMCO Properties, L.P., (the "AIMCO operating partnership") through
its wholly owned subsidiaries, AIMCO-GP, Inc. and AIMCO-LP, Inc. The Company
held an approximate 91% interest in the AIMCO operating partnership as of March
31, 1999. AIMCO-GP, Inc. is the sole general partner of the AIMCO operating
partnership.
 
     At March 31, 1999, AIMCO had 61,657,687 shares of Class A Common Stock
outstanding and the AIMCO operating partnership had 5,961,904 Partnership Common
Units ("Common OP Units") outstanding (excluding units held by the Company), for
a combined total of 67,619,591 shares and Common OP Units outstanding.
 
     As of March 31, 1999, AIMCO:
 
        - owned or controlled 63,069 units in 240 apartment properties;
 
        - held an equity interest in 168,817 units in 891 apartment properties;
          and
 
        - managed 141,523 units in 940 apartment properties for third party
          owners and affiliates.
 
NOTE 2 -- BASIS OF PRESENTATION
 
  Principles of Consolidation
 
     The accompanying consolidated financial statements include the accounts of
AIMCO, the AIMCO operating partnership, majority owned subsidiaries and
controlled real estate limited partnerships. Interests held by limited partners
in real estate partnerships controlled by the Company are reflected as minority
interest in other entities. All significant intercompany balances and
transactions have been eliminated in consolidation. The assets of
property-owning limited partnerships and limited liability companies owned or
controlled by AIMCO or the AIMCO operating partnership are generally not
available to pay creditors or secure the obligations of AIMCO or the AIMCO
operating partnership.
 
     After payment of distributions to holders of partnership preferred units
("Preferred OP Units" and together with Common OP Units, "OP Units"), the AIMCO
operating partnership's remaining income is allocated to holders of Common OP
Units based on the weighted average number of Common OP Units outstanding during
the period. The AIMCO operating partnership records the issuance of Common OP
Units and the assets acquired in purchase transactions based on the market price
of the Company's Class A Common Stock at the date of execution of the purchase
contract. The holders of the Common OP Units receive distributions, prorated
from the date of admittance, in an amount equivalent to the dividends paid to
holders of Class A Common Stock.
 
     After holding the Common OP Units for one year, the limited partners
generally have the right to redeem their Common OP Units for cash.
Notwithstanding that right, the AIMCO operating partnership may elect to acquire
some or all of the Common OP Units tendered for redemption in exchange for
shares of Class A Common Stock in lieu of cash.
 
  Investments in Unconsolidated Subsidiaries
 
     The Company has investments in numerous subsidiaries. Investments in
entities in which the Company does not have control are accounted for under the
equity method. Under the equity method, the Company's pro-rata share of the
earnings or losses of the entity for the periods being presented is included in
equity in earnings (losses) from unconsolidated subsidiaries.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
  Investments in Unconsolidated Real Estate Partnerships
 
     The Company owns general and limited partnership interests in numerous
partnerships that own multi-family apartment properties. Investments in real
estate partnerships in which the Company does not have control, are accounted
for under the equity method. Under the equity method, the Company's pro-rata
share of the earnings or losses of the entity for the periods being presented is
included in equity in earnings (losses) from unconsolidated real estate
partnerships.
 
  Notes Receivable from Unconsolidated Subsidiaries and Real Estate Partnerships
 
     Notes receivable from unconsolidated subsidiaries and real estate
partnerships are recorded at original basis, net of any allowance for
impairment. The Company recognizes interest income on notes receivable as
earned, in accordance with the terms of the notes. Interest income is not
recorded on individual notes receivable if management believes the interest is
not collectible.
 
  Earnings per Share
 
     Earnings per share is calculated based on the weighted average number of
shares of common stock, common stock equivalents and dilutive convertible
securities outstanding during the period.
 
  Interim Information
 
     The accompanying unaudited consolidated financial statements of the Company
as of March 31, 1999 and for the three months ended March 31, 1999 and 1998 have
been prepared in accordance with generally accepted accounting principles for
interim financial information. Accordingly, they do not include all of the
information and footnotes required by generally accepted accounting principles
for complete financial statements. In the opinion of management, all adjustments
considered necessary for a fair presentation have been included and all such
adjustments are of a recurring nature.
 
     The consolidated financial statements should be read in conjunction with
the audited consolidated financial statements and notes thereto included in the
Annual Report on Form 10-K for the year ended December 31, 1998. It should be
understood that accounting measurements at interim dates inherently involve
greater reliance on estimates than at year-end. The results of operations for
the interim periods presented are not necessarily indicative of the results for
the entire year.
 
  Reclassification
 
     Certain reclassifications have been made to prior period financial
statements to conform to the current period presentation.
 
NOTE 3 -- IPT MERGER
 
     As a result of its merger with Insignia Financial Group, Inc. on October 1,
1998, AIMCO acquired approximately 51% of the outstanding shares of beneficial
interest of Insignia Properties Trust ("IPT"). On February 26, 1999, AIMCO
acquired, through a merger, the remaining 49% of IPT. Pursuant to the merger,
each of the outstanding shares of IPT that were not held by AIMCO were converted
into the right to receive 0.3601 shares of Class A Common Stock for each share
of IPT common stock, resulting in the issuance of approximately 4.3 million
shares of Class A Common Stock (with a recorded value of approximately $158.8
million).

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
NOTE 4 -- COMMITMENTS
 
  High Performance Units
 
     In January 1998, AIMCO's operating partnership sold an aggregate of 15,000
of its Class I High Performance Partnership Units (the "High Performance Units")
to a joint venture formed by fourteen members of AIMCO's senior management, and
to three of its independent directors for $2.1 million in cash. The High
Performance Units have nominal value unless the Company's total return, defined
as dividend income plus share price appreciation, over the three year period
ending December 31, 2000, is at least 30% and exceeds the industry average, as
determined by a peer group index, by at least 15% (the "Total Return"). At the
conclusion of the three year period, if the Company's Total Return satisfies
these criteria, the holders of the High Performance Units will receive
distributions and allocations of income and loss from the AIMCO operating
partnership in the same amounts and at the same times as would holders of a
number of Common OP Units equal to the quotient obtained by dividing (i) the
product of (a) 15% of the amount by which the Company's cumulative Total Return
over the three year period exceeds the greater of 115% of a peer group index or
30% (such excess being the "Excess Return"), multiplied by (b) the weighted
average market value of the Company's outstanding Class A Common Stock and
Common OP Units, by (ii) the market value of one share of Class A Common Stock
at the end of the three year period. The three year measurement period will be
shortened in the event of a change of control of the Company. Unlike Common OP
Units, the High Performance Units are not redeemable or convertible into Class A
Common Stock unless a change of control of the Company occurs. Because there is
substantial uncertainty that the High Performance Units will have more than
nominal value due to the required Total Return over the three year term, the
Company has not recorded any value to the High Performance Units. If the
measurement period would have ended March 31, 1999, the Excess Return would have
been $0 and the value of the High Performance Units would have been $0, and such
High Performance Units would have had no dilutive effect on net income per
share.
 
NOTE 5 -- DEBT
 
     In February 1999, the Company terminated its $50 million secured credit
facility with Washington Mortgage Financial Group, Ltd. and repaid all
outstanding borrowings with proceeds from new long-term, fully amortizing notes
payable totaling $58.2 million secured by certain properties that previously
secured the credit facility.
 
     In February and March 1999, the Company incurred in the aggregate $125.4
million of long-term, fixed rate, fully amortizing notes payable secured by 20
properties in separate loan transactions. The Company used $8.2 million of the
net proceeds from the financings to refinance existing notes payable and $117.2
million of net proceeds from the financings to repay debt under the interim loan
agreement with Lehman Brothers Inc. As of March 31, 1999, the balance
outstanding under the interim loan agreement was $21 million, under the credit
facility was $58.3 million, and under the IPT credit agreement was $45 million.
The amount available under the credit facility at March 31, 1999 was $40.5
million.

NOTE 8 -- INDUSTRY SEGMENTS
 
     The Company owns and operates multi-family apartment communities throughout
the United States and Puerto Rico which generated rental and other property
related income through the leasing of apartment units to a diverse base of
tenants. The Company separately evaluates the performance of each of its
apartment communities. However, because each of the apartment communities have
similar economic characteristics, facilities, services and tenants, the
apartment communities have been aggregated into a single apartment communities
segment. All segment disclosures are included in or can be derived from the
Company's consolidated financial statements.
 
     All revenues are from external customers and no revenues are generated from
transactions with other segments. There are no tenants which contributed 10% or
more of the Company's total revenues during the three months ended March 31,
1999 and March 31, 1998.

1999, and expects to acquire the remaining apartment community in May 1999.
 
  Conversion of Preferred Stock
 
     On May 12, 1999, the Company notified the holders of the Class J Preferred

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS.
 
  Overview
 
     As of March 31, 1999, the Company owned or managed 373,409 apartment units,
comprised of 63,069 units in 240 apartment communities owned or controlled by
the Company (the "Owned Properties"), 168,817 units in 891 apartment communities
in which the Company has an equity interest (the "Equity Properties") and
141,523 units in 940 apartment communities which the Company manages for third
parties and affiliates (the "Managed Properties" and together with the Owned
Properties and the Equity Properties, the "AIMCO Properties"). The apartment
communities are located in 49 states, the District of Columbia and Puerto Rico.
 
     The following discussion contains forward-looking statements that are
subject to significant risks and uncertainties. There are several important
factors that could cause actual results to differ materially from the results
anticipated by the forward-looking statements contained in the following
discussion. Such factors and risks include, but are not limited to: financing
risks, including the risk that the Company's cash flow from operations may be
insufficient to meet required payments of principal and interest on its debt;
real estate risks, including variations of real estate values and the general
economic climate in local markets and competition for tenants in such markets;
acquisition and development risks, including the failure of acquisitions to
perform in accordance with projections; and possible environmental liabilities,
including costs which may be incurred due to necessary remediation of
contamination of properties presently owned or previously owned by the Company.
In addition, the Company's continued qualification as a REIT involves the
application of highly technical and complex provisions of the Internal Revenue
Code. Readers should carefully review the financial statements and the notes
thereto, as well as the risk factors described in documents the Company files
from time to time with the Securities and Exchange Commission.
 
RESULTS OF OPERATIONS
 
  Comparison of the Three Months Ended March 31, 1999 to the Three Months Ended
March 31, 1998
 
  Net Income
 
     The Company recognized net income of $14.0 million for the three months
ended March 31, 1999, compared to $21.6 million for the three months ended March
31, 1998. The decrease in net income of $7.6 million, or 35%, was primarily the
result of a significant increase in the non-cash expenses (i.e., depreciation of
real property and amortization of management contracts) and general and
administrative expenses associated with the acquisition of Insignia Financial
Group, Inc. ("Insignia"), Ambassador Apartments, Inc. ("Ambassador") and the
purchase of thirty properties (the "1998 Acquisitions") during 1998. The
decrease in net income was also attributable to the increased interest expense
associated with indebtedness which was assumed or incurred in connection with
the acquisitions described above, a decrease in income from the service company
business, the sale of five properties in 1998 (the "1998 Sold Properties") and
one property in 1999 (the "1999 Sold Property"). These factors are discussed in
more detail in the following paragraphs.

     Property operating expenses, consisting of on-site payroll costs, utilities

costs, repairs and maintenance, advertising and marketing, property taxes and

three months ended March 31, 1999, compared to $26.3 million for the three
months ended March 31, 1998, an increase of $16.9 million or 64.3%. Operating

SERVICE COMPANY BUSINESS
 
     The Company's share of income (loss) from the service company business was
$(0.3) million for the three months ended March 31, 1999, compared to $2.7
million for the three months ended March 31, 1998. The decrease in service
company business income of $3.0 million was primarily due to a decrease in fees
for services provided by the Company to real estate partnerships for customary
services.
 
GENERAL AND ADMINISTRATIVE EXPENSES
 
     General and administrative expenses increased from $2.0 million for the
three months ended March 31, 1998 to $3.7 million for the three months ended
March 31, 1999, an 85% increase. The increase is primarily due to additional
corporate costs and additional employee salaries associated with the merger with
Ambassador in May 1998 and the merger with Insignia in October 1998. In
addition, due to the growth of the Company, several new departments have been
added including legal, tax and tender coordination, as well as increased levels
of personnel in the accounting and finance departments.
 
INTEREST EXPENSE
 
     Interest expense, which includes the amortization of deferred financing
costs, totaled $31.3 million for the three months ended March 31, 1999, compared
to $15.4 million for the three months ended March 31, 1998, an increase of $15.9
million, or 103.2%. The increase was primarily due to interest expense incurred
in connection with the acquisition of interests in Ambassador and Insignia and
interest expense incurred in connection with 1998 acquisitions.

INTEREST INCOME
 
     Interest income totaled $10.4 million for the three months ended March 31,
1999, compared to $6.1 million for the three months ended March 31, 1998. The
increase of $4.3 million is primarily due to interest earned on loans made by
the Company to partnerships in which the Company acts as the general partner.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     The Company expects to meet its short-term liquidity requirements,
including property acquisitions, tender offers, refinancing of short-term debt
with long-term, fixed rate, fully amortizing debt, secured or unsecured
short-term indebtedness (including indebtedness under the Company's credit
facilities), the issuance of debt securities, OP Units or equity securities in
public offerings or private placements, and cash generated from operations.
 
     In August 1998, AIMCO and the AIMCO operating partnership filed a shelf
registration statement with the Securities and Exchange Commission ("SEC") with
respect to an aggregate of $1,268 million of debt and equity securities of AIMCO
(of which $268 million was carried forward from AIMCO's 1997 shelf registration
statement) and $500 million of debt securities of AIMCO operating partnership.
The registration statement was declared effective by the SEC on December 10,
1998. As of March 31, 1999, the Company had $1,143 million available and the
AIMCO operating partnership had $500 million available from this registration
statement.
 
     At March 31, 1999, the Company had $38.6 million in cash and cash
equivalents. In addition, the Company had $55.3 million of restricted cash
primarily consisting of reserves and impounds held by lenders for capital
expenditures, property taxes and insurance. The Company's principal demands for
liquidity include normal operating activities, payments of principal and
interest on outstanding debt, capital improvements, acquisitions of or
investments in properties, dividends paid to its stockholders and distributions
paid to minority limited partners in the AIMCO operating partnership. The
Company considers its cash provided by operating activities, and funds available
under its credit facilities, to be adequate to meet short-term liquidity
demands. The Company utilizes its revolving credit facilities for general
corporate purposes and to fund investments on an interim basis.
 
     In February 1999, the Company terminated its $50 million secured credit
facility with Washington Mortgage Financial Group, Ltd. and repaid all
outstanding borrowings with proceeds from new long-term, fully amortizing notes
payable totaling $58.2 million secured by certain properties that previously
secured the credit facility.
 
     In February and March 1999, the Company incurred in the aggregate $125.4
million of long-term, fixed rate, fully amortizing notes payable secured by 20
properties in separate loan transactions. The Company used $8.2 million of the
net proceeds from the financings to refinance existing notes payable, and $117.2
million of net proceeds from the financings to repay debt under the interim loan
agreement with Lehman Brothers Inc. As of March 31, 1999, the balance
outstanding under the interim loan agreement was $21 million, under the credit
facility was $58.3 million, and under the IPT credit agreement was $45 million.
The amount available under the credit facility at March 31, 1999 was $40.5
million.
 
     From time to time, the Company has offered to acquire and, in the future,
may offer to acquire the interests held by third party investors in certain
limited partnerships for which the Company acts as general partner. Any such
acquisitions will require funds to pay the cash purchase price for such
interests. During the quarter ended March 31, 1999, the Company made separate
offers to the limited partners of 106 partnerships owning 326 properties to
acquire their limited partnership interests. The Company paid approximately
$18.2 million in cash, (including transaction costs), to acquire limited
partnership interests pursuant to the offers.
 
     On February 18, 1999, the Company issued 5,000,000 shares of newly created
Class K Convertible Cumulative Preferred Stock, par value $.01 per share in a
public offering. The net proceeds of $120.6 million were used to repay certain
indebtedness and for working capital. For three years, holders of the Class K

of Directors, annual cash

dividends in an amount per share equal to the greater of (i) $2.00 per year
(equivalent to 8% of the liquidation preference), or (ii) the cash dividends
payable on the number of shares of Class A Common Stock into which a share of
Class K Preferred Stock is convertible. Beginning with the third anniversary of
the date of original issuance, holders of Class K Preferred Stock will be
entitled to receive an amount per share equal to the greater of (i) $2.50 per
year (equivalent to 10% of the liquidation preference), or (ii) the cash
dividends payable on the number of Class A Common Stock into which a share of
Class K Preferred is convertible. The Class K Preferred Stock is senior to the
Class A Common Stock as to dividends and liquidation. Upon any liquidation,
dissolution or winding up of AIMCO, before payment or distributions by AIMCO may
be made to any holders of Class A Common Stock, the holders of the Class K
Preferred Stock are entitled to receive a liquidation preference of $25 per
share, plus accumulated, accrued and unpaid dividends.
 
CAPITAL EXPENDITURES
 
     For the quarter ended March 31, 1999, the Company spent $8.7 million for
Capital Replacements (expenditures for routine maintenance of a property), $0.9
million for Initial Capital Expenditures or "ICE" (expenditures at a property
that have been identified, at the time the property is acquired, as expenditures
to be incurred within one year of the acquisition), and $10.0 million for
construction and capital enhancements (amenities that add a material new feature
or revenue source at a property). These expenditures were funded by borrowings
under the Company's primary credit facility, working capital reserves and net
cash provided by operating activities. During 1999, the Company will provide an
allowance for capital replacements of $300 per apartment unit. ICE and capital
enhancements will primarily be funded by cash from operating activities and
borrowings under the Company's primary credit facility.
 
FUNDS FROM OPERATIONS
 
     The Company measures its economic profitability based on funds from
operations ("FFO"), less a reserve for Capital Replacements of $300 per
apartment unit. The Company's management believes that FFO, less such a reserve,
provides investors with an understanding of the Company's ability to incur and
service debt and make capital expenditures. The Board of Governors of the
National Association of Real Estate Investment Trusts ("NAREIT") defines FFO as
net income (loss), computed in accordance with generally accepted accounting
principles ("GAAP"), excluding gains and losses from debt restructuring and
sales of property, plus real estate related depreciation and amortization
(excluding amortization of financing costs), and after adjustments for
unconsolidated partnerships and joint ventures. The Company calculates FFO based
on the NAREIT definition, as adjusted for the minority interest in the AIMCO
operating partnership, amortization of goodwill, the non-cash deferred portion
of the income tax provision for unconsolidated subsidiaries and less the payment
of dividends on preferred stock. FFO should not be considered an alternative to
net income or net cash flows from operating activities, as calculated in
accordance with GAAP, as an indication of the Company's performance or as a
measure of liquidity. FFO is not necessarily indicative of cash available to
fund future cash needs. In addition, there can be no assurance that the
Company's basis for computing FFO is comparable with that of other real estate
investment trusts.

CONTINGENCIES
 
  HUD Approvals and Enforcement
 
     A significant number of apartment units owned or managed by AIMCO are
subject to regulation by the U.S. Department of Housing and Urban Development
("HUD"). Under its regulations, HUD reserves the right to approve the owner and
the manager of HUD-insured and HUD-assisted properties, as well as their
"principals" (e.g., general partners, stockholders with a 10% or greater
interest, officers and directors) in connection with the acquisition of a
property, participation in HUD programs or the award of a management contract.
This approval process is commonly referred to as "2530 Clearance." HUD monitors
the performance of properties with HUD-insured mortgage loans. HUD also monitors
compliance with applicable regulations, and takes performance and compliance
into account in approving the acquisition of management of HUD-assisted
properties. In the event of instances of unsatisfactory performance or
regulatory violations, the HUD office with jurisdiction over a property has the
authority to enter a "flag" into the computerized 2530 Clearance system. If one
or more flags have been entered, a decision whether to grant 2530 Clearance is
then subject to review by HUD's Multi-family Participation Review Committee in
Washington, D.C. (the "2530 Committee"). HUD also has the authority to suspend
or deny property owners and managers from participation in HUD programs with
respect to additional assistance within a geographic region through imposition
of a Limited Denial of Participation by any HUD office or nationwide for
violations of HUD regulatory requirements. As a result of certain mortgage
defaults and unsatisfactory ratings received by NHP Management Company, an
unconsolidated subsidiary of AIMCO, and NHP Incorporated (together "NHP") in
years prior to their acquisition in December 1997 by AIMCO, HUD believes that
the 2530 Committee must review any application for 2530 Clearance filed by
AIMCO. In December 1998 and thereafter, AIMCO
 
                                       18
   20
 
received approval of numerous 2530 applications and had no unresolved flags in
the 2530 system as of March 31, 1999.
 
     NHP has received subpoenas from the HUD Inspector General requesting
documents relating to any arrangement whereby NHP or any of its affiliates
provides or has provided compensation to owners of HUD multi-family projects in
exchange for or in connection with property management of a HUD project, and
related matters. AIMCO believes that other owners and managers of HUD projects
have received similar subpoenas. Documents provided by AIMCO to the HUD
Inspector General relating to certain NHP acquisitions of property management
rights for HUD projects may be responsive to the subpoena. AIMCO believes that
its operations are in compliance, in all material respects, with all laws, rules
and regulations relating to HUD-assisted or HUD-insured properties. Although no
action has been initiated against AIMCO or, to AIMCO's knowledge, any owner of a
HUD property managed by AIMCO, if any such action is taken in the future, it
could ultimately affect existing arrangements with respect to HUD projects,
affect AIMCO's ability to receive 2530 Clearances or otherwise have a material
adverse effect on AIMCO's results of operations.
 
     AIMCO believes that the 2530 Committee will continue to apply the 2530
Clearance process to large management portfolios such as AIMCO's with discretion
and flexibility. If HUD were to disapprove AIMCO as property manager for one or
more affordable properties, AIMCO's ability to obtain property management
revenues from additional properties subject to HUD regulation would be impaired.
 
  Environmental
 
     Various Federal, state and local laws subject property owners or operators
to liability for the costs of removal or remediation of certain hazardous
substances present on a property. Such laws often impose liability without
regard to whether the owner or operator knew of, or was responsible for, the
release of the hazardous substances. The presence of, or the failure to properly
remediate, hazardous substances may adversely affect occupancy at contaminated
apartment communities and our ability to sell or borrow against contaminated
properties. In addition to the costs associated with investigation and
remediation actions brought by governmental agencies, the presence of hazardous
wastes on a property could result in personal injury or similar claims by
private plaintiffs. Various laws also impose liability for the cost of removal
or remediation of hazardous substances at the disposal or treatment facility.
Anyone who arranges for the disposal or treatment of hazardous or toxic
substances is potentially liable under such laws. These laws often impose
liability whether or not the person arranging for the disposal ever owned or
operated the disposal facility. In connection with the ownership, operation and
management of our properties, we could potentially be liable for environmental
liabilities or costs associated with our properties or properties we may acquire
or manage in the future.
 
HIGH PERFORMANCE UNITS
 
     In January 1998, AIMCO's operating partnership sold an aggregate of 15,000
of its Class I High Performance Partnership Units (the "High Performance Units")
to a joint venture formed by fourteen members of AIMCO's senior management, and
to three of its independent directors for $2.1 million in cash. The High
Performance Units have nominal value unless the Company's total return, defined
as dividend income plus share price appreciation, over the three year period
ending December 31, 2000, is at least 30% and exceeds the industry average, as
determined by a peer group index, by at least 15% (the "Total Return"). At the
conclusion of the three year period, if the Company's Total Return satisfies
these criteria, the holders of the High Performance Units will receive
distributions and allocations of income and loss from the AIMCO operating
partnership in the same amounts and at the same times as would holders of a
number of Common OP Units equal to the quotient obtained by dividing (i) the
product of (a) 15% of the amount by which the Company's cumulative Total Return
over the three year period exceeds the greater of 115% of a peer group index or
30% (such excess being the "Excess Return"), multiplied by (b) the weighted
average market value of the Company's outstanding Class A Common Stock and
Common OP Units, by (ii) the market value of one share of Class A Common Stock
at the end of the three year period. The three year measurement period will be
shortened in the event of a change of control of the Company. Unlike Common OP
Units, the High
                                       19
   21
 
Performance Units are not redeemable or convertible into Class A Common Stock
unless a change of control of the Company occurs. Because there is substantial
uncertainty that the High Performance Units will have more than nominal value
due to the required Total Return over the three year term, the Company has not
recorded any value to the High Performance Units. If the measurement period
would have ended March 31, 1999, the Excess Return would have been $0 and the
value of the High Performance Units would have been $0, and such High
Performance Units would have had no dilutive effect on net income per share.
 
YEAR 2000 READINESS DISCLOSURE
 
    GENERAL DESCRIPTION OF THE YEAR 2000 ISSUE AND THE NATURE AND EFFECTS OF THE
    YEAR 2000 ON INFORMATION TECHNOLOGY (IT) AND NON-IT SYSTEMS
 
     The Year 2000 issue is the result of computer programs being written using
two digits rather than four digits to define the applicable year. Any of the
Company's computer programs or hardware that have date-sensitive software or
embedded chips may recognize a date using "00" as the year 1900 rather than the
year 2000. This could result in a system failure or miscalculations causing
disruptions of operations, including, among other things, a temporary inability
to process transactions, send invoices, or engage in similar normal business
activities.
 
     Over the past two years, the Company has determined that it will be
required to modify or replace significant portions of its software and certain
hardware so that those systems will properly utilize dates beyond December 31,
1999. The Company presently believes that with modifications or replacements of
existing software and certain hardware, the Year 2000 issue can be mitigated.
However, if such modifications and replacements are not made, or are not
completed in time, the Year 2000 issue could have a material impact on the
operations of the Company.
 
     The Company's plan to resolve Year 2000 issues involves four phases:
assessment, remediation, testing, and implementation. To date, the Company has
fully completed its assessment of all information systems that could be
significantly affected by the Year 2000, and has begun the remediation, testing
and implementation phases on both hardware and software systems. Assessments are
continuing in regards to embedded systems. The status of each is detailed below.
 
STATUS OF PROGRESS IN BECOMING YEAR 2000 COMPLIANT, INCLUDING TIMETABLE FOR
COMPLETION OF EACH REMAINING PHASE
 
  Computer Hardware
 
     During 1997 and 1998, AIMCO identified all of the computer systems at risk
and formulated a plan to repair or replace each of the affected systems. During
1997, when AIMCO merged with NHP, the mainframe system used by NHP was Year 2000
compliant. In August 1998, the Year 2000 compliant system became fully
functional for the entire Company.
 
     In addition to the mainframe, PC-based network servers, routers and desktop
PCs were analyzed for compliance. AIMCO has begun to replace each of the
non-compliant network connections and desktop PCs and, as of March 31, 1999, had
completed approximately 85% of this effort.
 
     The total cost to replace the PC-based network servers, routers and desktop
PCs is expected to be approximately $1.5 million, of which $1.3 million has been
incurred to date. The remaining network connections and desktop PCs are expected
to be upgraded to Year 2000 compliant systems by June 30, 1999.
 
  Computer Software
 
     AIMCO utilizes a combination of off-the-shelf, commercially available
software programs as well as custom-written programs that are designed to fit
specific needs. Both of these types of programs were studied, and implementation
plans written and executed with the intent of repairing or replacing any
non-compliant software programs.
 
                                       20
   22
 
     In 1997, when AIMCO merged with NHP, the core financial system used by NHP
was Year 2000 compliant. During 1998, AIMCO integrated all of its core financial
systems to this compliant system for general ledger and financial reporting
purposes.
 
     In 1997, AIMCO determined that the software used for property management
and rent collection was not Year 2000 compliant. During 1998, AIMCO implemented
a Year 2000 compliant system at each of its owned or managed properties, at a
cost of $1.4 million. During 1998, AIMCO acquired 82 properties and acquired the
Insignia multi-family business. Insignia owned or managed 1,100 properties. As
properties are acquired, AIMCO converts the existing property management and
rent collection systems to AIMCO's Year 2000 compliant systems. The estimated
additional costs to convert such systems at all recently acquired properties,
including those acquired from Insignia, is $200,000, and the implementation and
testing process is expected to be completed by June 30, 1999.
 
     The final software area is the office software and server operating
systems. AIMCO has upgraded all non-compliant office software systems on each PC
and has upgraded 80% of the server operating systems. The remaining server
operating systems are planned to be upgraded to be Year 2000 compliant by June
30, 1999.
 
  Operating Equipment
 
     AIMCO has operating equipment, primarily at the property sites, which
needed to be evaluated for Year 2000 compliance. In September 1997, AIMCO began
taking a census and inventory of embedded systems (including those devices that
use time to control systems and machines at specific properties, for example,
elevators, heating, ventilating and air conditioning systems, security and alarm
systems, etc.)
 
     The Company has chosen to focus its attention mainly upon security systems,
elevators, heating, ventilating and air conditioning systems, telephone systems
and switches, and sprinkler systems. While this area is the most difficult to
fully research adequately, management has not yet found any major non-
compliance issues that put AIMCO at risk financially or operationally. AIMCO
intends to have a third-party conduct an audit of these systems and report their
findings by June 30, 1999.
 
     Any of the above operating equipment that has been found to be
non-compliant to date has been replaced or repaired. To date, these have
consisted only of security systems and phone systems. As of March 31, 1999,
AIMCO has evaluated approximately 86% of the operating equipment for Year 2000
compliance.
 
     The total cost incurred as of March 31, 1999 to replace or repair the
operating equipment was approximately $70,000. AIMCO estimates the cost to
replace or repair any remaining operating equipment is approximately $325,000,
and AIMCO expects to be completed by June 30, 1999.
 
     AIMCO continues to have "awareness campaigns" throughout the organization
designed to raise awareness and report any possible compliance issues regarding
operating equipment within the enterprise.
 
  Nature and Level of Importance of Third Parties and Their Exposure to the Year
  2000
 
     AIMCO continues to conduct surveys of its banking and other vendor
relationships to assess risks regarding their Year 2000 readiness. AIMCO has
banking relationships with three major financial institutions, all of which have
indicated their compliance efforts will be complete before May 1999. AIMCO has
updated data transmission standards with two of the three financial
institutions. AIMCO's contingency plan in this regard is to move accounts from
any institution that cannot be certified Year 2000 compliant by June 1, 1999.
 
     The Company does not rely heavily on any single vendor for goods and
services, and does not have significant suppliers and subcontractors who share
information systems with the Company (external agents). To date, the Company is
not aware of any external agent with a Year 2000 compliance issue that would
materially impact the Company's results of operations, liquidity, or capital
resources. However, the Company has no means of ensuring that external agents
will be Year 2000 compliant.
 
     Management does not believe that the inability of external agents to
complete their Year 2000 remediation process in a timely manner will have a
material impact on the financial position or results of
 
                                       21
   23
 
operations of the Company. However, the effect of non-compliance by external
agents is not readily determinable.
 
  Costs to Address Year 2000
 
     The total cost of the Year 2000 project is estimated at $3.5 million and is
being funded from operating cash flows. To date, the Company has incurred
approximately $2.8 million ($0.6 million expensed and $2.2 million capitalized
for new systems and equipment) related to all phases of the Year 2000 project.
Of the total remaining project costs, approximately $0.5 million is attributable
to the purchase of new software and operating equipment, which will be
capitalized. The remaining $0.2 million relates to repair of hardware and
software and will be expensed as incurred.
 
  Risks Associated with the Year 2000
 
     Management believes it has an effective program in place to resolve the
Year 2000 issue in a timely manner. As noted above, the Company has not yet
completed all necessary phases of the Year 2000 program. In the event that the
Company does not complete any additional phases, certain worst case scenarios
could occur. The worst case scenarios include elevators, security and heating,
ventilating and air conditioning systems that read incorrect dates and operate
with incorrect schedules (e.g., elevators will operate on Monday as if it were
Sunday). Although such a change would be annoying to residents, it is not
business critical.
 
     In addition, disruptions in the economy generally resulting from Year 2000
issues could also adversely affect the Company. The Company could be subject to
litigation for, among other things, computer system failures, equipment
shutdowns or a failure to properly date business records. The amount of
potential liability and lost revenue cannot be reasonably estimated at this
time.
 
  Contingency Plans Associated with the Year 2000
 
     The Company has contingency plans for certain critical applications and is
working on such plans for others. These contingency plans involve, among other
actions, manual workarounds and selecting new relationships for such activities
as banking relationships and elevator operating systems.
 
INFLATION
 
     Substantially all of the leases at the Company's apartment properties are
for a period of six months or less, allowing, at the time of renewal, for
adjustments in the rental rate and the opportunity to re-lease the apartment
unit at the prevailing market rate. The short-term nature of these leases
generally serves to minimize the risk to the Company of the adverse effect of
inflation and the Company does not believe that inflation has had a material
adverse impact on its revenues.
 
LITIGATION
 
     In connection with the Company's offers to purchase interests in limited
partnerships that own properties, the Company and its affiliates are sometimes
subject to legal actions, including allegations that such activities may involve
breaches of fiduciary duties to the limited partners of such partnerships or
violations of the relevant partnership agreements. The Company believes it
complies with its fiduciary obligations and relevant partnership agreements, and
does not expect such legal actions to have a material adverse effect on the
consolidated financial condition or results of operations of the Company and its
subsidiaries taken as a whole. The Company may incur costs in connection with
the defense or settlement of such litigation, which could adversely affect the
Company's desire or ability to complete certain transactions and thereby have a
material adverse effect on the Company and its subsidiaries.
 
ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
 
     The Company's primary market risk exposure relates to changes in interest
rates. The Company is not subject to any foreign currency exchange rate risk or
commodity price risk, or any other material market rate
 
                                       22
   24
 
or price risks. The Company uses predominantly long-term, fixed-rate and
self-amortizing non-recourse debt in order to avoid the refunding or repricing
risks of short-term borrowings. The Company uses short-term debt financing and
working capital primarily to fund acquisitions and generally expects to
refinance such borrowings with proceeds from equity offerings or long term debt
financings.
 
     The Company had $209.6 million of variable rate debt outstanding at March
31, 1999, which represents 13.0% of the Company's total outstanding debt. Based
on this level of debt, an increase in interest rates of 1% would result in the
Company's income and cash flows being reduced by $2.1 million on an annual
basis.
 
     From time to time, the Company enters into interest rate lock agreements to
obtain what the Company considers advantageous pricing for future anticipated
debt issuances.
 
     The estimated aggregate fair value of the Company's cash and cash
equivalents, receivables, payables and short-term secured and unsecured debt as
of March 31, 1999 is assumed to approximate their carrying value due to their
relatively short terms. Management further believes that, after consideration of
interest rate agreements, the fair market value of the Company's secured
tax-exempt bond debt and secured long-term debt approximates their carrying
value, based on market comparisons to similar types of debt instruments having
similar maturities.
 
                           PART II. OTHER INFORMATION
 
ITEM 2. CHANGES IN SECURITIES AND USE OF PROCEEDS
 
     On February 18, 1999, AIMCO issued 5,000,000 shares of newly created Class
K Convertible Cumulative Preferred Stock, par value $.01 per share ("Class K
Preferred Stock") in a public offering. The net proceeds of $120.6 million were
used to repay certain indebtedness and for working capital. For three years,
holders of the Class K Preferred Stock are entitled to receive, when, as and if
declared by the Board of Directors, annual cash dividends in an amount per share
equal to the greater of (i) $2.00 per year (equivalent to 8% of the liquidation
preference), or (ii) the cash dividends payable on the number of shares of Class
A Common Stock into which a share of Class K Preferred Stock is convertible.
Beginning with the third anniversary of the date of original issuance, holders
of Class K Preferred Stock will be entitled to receive an amount per share equal
to the greater of (i) $2.50 per year (equivalent to 10% of the liquidation
preference), or (ii) the cash dividends payable on the number of Class A Common
Stock into which a share of Class K Preferred is convertible. The Class K
Preferred Stock is senior to the Class A Common Stock as to dividends and
liquidation. Upon any liquidation, dissolution or winding up of AIMCO, before
payment or distributions by AIMCO shall be made to any holders of Class A Common
Stock, the holders of the Class K Preferred Stock shall be entitled to receive a
liquidation preference of $25 per share, plus accumulated, accrued and unpaid
dividends.
 
     From time to time during the quarter, AIMCO issued shares of Class A Common
Stock in exchange for Common OP Units tendered to the AIMCO operating
partnership for redemption in accordance with the terms and provisions of the
agreement of limited partnership of the AIMCO operating partnership. Such shares
are issued based on an exchange ratio of one share for each Common OP Unit. The
shares are issued in exchange for Common OP Units in private transactions exempt
from registration under the Securities Act of 1933, as amended (the "Securities
Act"), pursuant to Section 4(2) thereof. During the three months ended March 31,
1999, 322,801 shares of Class A Common Stock were issued in exchange for Common
OP Units.
