We are described in more detail below. Recent accomplishments in the execution of such strategies are discussed in the Executive Overview in Item 7.

In addition, our apartment communities we want to add to our portfoliocompete for residents with other housing alternatives, including other rental apartments and the pricecondominiums, and single-family homes that we payare available for rent, as well as new and existing condominiums and single-family homes for sale. Competitive residential housing, as well as household formation and job creation in such acquisitions;a particular area, could adversely affect our ability to financelease apartment homes and to increase or refinance communities in our portfolio and the cost of such financing; and our ability to dispose of communities we no longer desire to retain in our portfolio and the timing and price available to us when we seek to dispose of such communities.

Certain of Aimco’sour operations, or a portion thereof, including property management and risk management are conducted through taxable REIT subsidiaries, each of which we refer to as a TRS. A TRS is a subsidiary C-corporation that has not elected REIT status and, as such, is subject to United States federal corporate income tax. We use TRS entities to facilitate our ability to offer certain services andperform activities to our residents and investment partners that cannot be offeredperformed directly by a REIT. We also use TRS entities to hold investments in certain apartment communities.

Apartment development is subject to various laws, ordinances, and regulations, including those concerning entitlement, building, health and safety, site and building design, environment, zoning, sales, and similar matters apply to or affect the real estate development industry.

Apartment communities and their owners are subject to various laws, ordinances, and regulations, including those related to real estate broker licensing and regulations relating to recreational facilities such as swimming pools, activity centers, and other common areas.

Changes in laws increasing the potential liability for environmental conditions existing on apartment communities or increasing the restrictions on discharges or other conditions, as well as changes in laws affecting development, construction, and safety requirements, may result in significant unanticipated expenditures, which wouldcould adversely affect our net income and cash flows from operating activities.

In addition, existing rent control laws, as well as future enactment of rent control or rent stabilization laws, or other laws and ordinances regulating multifamily housing, such as eviction moratoriums and governmental lockdowns, may reduce rental revenue or increase operating costs in particular markets.

RISKS RELATED TO BUSINESS

Adverse economic and geopolitical conditions, health crises and dislocations in the credit markets could affect our ability to collect rents and late fees from tenants, and our ability to evict tenants, in addition to having other negative effects on our business, which in turn could adversely affect our financial condition and results of operations.

Adverse economic and geopolitical conditions, local, regional, national, or international health crises and dislocations in the credit markets could negatively impact our tenants and our operations. For example, the World Health Organization declared COVID-19 to be a pandemic on March 11, 2020. The outbreak of the COVID-19 pandemic has severely impacted global

economic activity and caused significant volatility and negative pressure in financial markets. The global impact of the outbreak has been rapidly evolving and many countries, including the United States, have reacted by instituting a wide variety of measures including states of emergency, mandatory quarantines, required business and school closures, implementing “shelter in place” orders, and restricting travel. In addition, many cities and states have enacted, or are considering enacting, exceptions to contractual obligations for residents and commercial tenants, including government mandated rent delays or other abatement measures or concessions or prohibitions on lease terminations or evictions. Many experts predict that the outbreak will trigger a period of material global economic slowdown or a global recession.

Factors that have negatively impacted, or would negatively impact, our operations or those of entities in which we hold a partial interest during the COVID-19 pandemic or another health crisis, adverse economic or geopolitical event or dislocation in the credit market include:

Given the ongoing and dynamic nature of the circumstances surrounding the COVID-19 pandemic, it is difficult to predict how significant the impact of this outbreak will be on the global economy, our residents and commercial tenants, our communities, and the operations of entities in which we hold a noncontrolling interest (including our interest in Maximus PM Mezzanine A LLC, the partnership owning the “Parkmerced Apartments”), or for how long disruptions are likely to continue. The extent of such impact will depend on developments, which are highly uncertain, rapidly evolving and cannot be predicted, including the ability to contain the virus, the duration of measures implemented, and the overall impact of these measures. Such developments, depending on their nature, duration, and intensity, could have a material adverse effect on our operating results and financial condition. The COVID-19 pandemic also may have the effect of heightening many of the other risks described below.

We do not have control over the partnership owning the Parkmerced Apartments, the operation of which could adversely affect our financial condition and results of operations.

Our indirect interest in the partnership owning the Parkmerced Apartments is subject to certain risks, including, but not limited to, exposure to the skill and capital of the controlling party and those resulting from the severe downturn in San Francisco rents, the ongoing disruption due to the COVID-19 pandemic and associated governmental response, and the current economic situation which may result in all or a portion of the loan not being repaid. Such risks could have a material adverse effect on our financial condition and results of operations.

Development, redevelopment, and construction risks could affect our profitability.

Our ability to fund necessary capital expenditures on our apartment communities depends on, among other things, our ability to generate net operating income in excess of required debt payments.payments and our ability to collect on interest and principal payments due to us pursuant to the terms of our arrangement with AIR relative to their interest in the partnership owning the Parkmerced Apartments. If we are unable to fund capital expenditures on our apartment communities, we may not be able to preserve the competitiveness of our communities, which could adversely affect their net operating income and long-term value.

Our ability to make payments to our investors depends on our ability to generate net operating income in excess of required debt payments and capital expenditure requirements.requirements and our ability to collect on interest and principal payments due to us pursuant to the terms of our arrangement with AIR relative to their interest in the partnership owning the Parkmerced Apartments. Our net operating income and liquidity may be adversely affected by events or conditions beyond our control, including:

We will initially be primarily dependent on AIR for our pipeline of development and redevelopment opportunities.

We will initially be primarily dependent on the pipeline of development and redevelopment opportunities that may be sourced by AIR for a significant portion of our anticipated growth and future revenue. Until we acquire additional sources of development and redevelopment opportunities, we will primarily depend on AIR. We may not be successful in identifying additional opportunities to further diversify and increase our sources of revenue and reduce our portfolio concentration in the near future or at all. The inability of AIR to source such opportunities for us efficiently or at all, could have a material adverse effect on us.

Our properties are geographically concentrated in California, Chicago, Florida, and in the Northeast region of the United States, which makes us more susceptible to regional and local adverse economic and other conditions than if we owned a more geographically diversified portfolio.

The majority of our properties are located in California, Chicago, Florida, and in the Northeast region of the United States. As a result, we are particularly susceptible to adverse economic or other conditions in these markets (such as periods of economic slowdown or recession, business layoffs or downsizing, industry slowdowns, relocations of businesses, increases in real estate and other taxes, and the cost of complying with governmental regulations or increased regulation), as well as to natural disasters (including earthquakes, storms, and hurricanes), potentially adverse effects of “global warming,” and other disruptions that occur in these markets (such as terrorist activity or threats of terrorist activity and other events), any of which may have a greater impact on the value of our assets or on our operating results than if we owned a more geographically diversified portfolio.

We cannot assure you that these markets will grow or that underlying real estate fundamentals will be favorable to owners, operators, and developers of office, multifamily or retail assets, or future development assets. Our operations may also be affected if competing assets are built in these markets. Moreover, submarkets within our core markets may be dependent upon a limited number of industries. Any adverse economic or other conditions in the Northeast region of the United States or in California, or any decrease in demand for office, multifamily, or retail assets could adversely impact our financial condition and results of operations.

Our development projects may subject us to certain liabilities, and we are subject to risks associated with developing properties in partnership with others.

We may hire and supervise third-party contractors to provide construction, engineering, and various other services for development projects. Certain of these contracts may be structured such that we are the principal rather than the agent. As a result, we may assume liabilities in the course of the project and be subjected to, or become liable for, claims for construction defects, negligent performance of work or other similar actions by third parties we have engaged.

Adverse outcomes of disputes or litigation could negatively impact our business, results of operations, and financial condition, particularly if we have not limited the extent of the damages for which we may be liable, or if our liabilities exceed the amounts of the insurance that we carry. Moreover, our tenants may seek to hold us accountable for the actions of contractors because of our role even if we have technically disclaimed liability as a legal matter, in which case we may determine it necessary to participate in a financial settlement for purposes of preserving the tenant or customer relationship or to protect our corporate brand. Acting as a principal may also mean that we pay a contractor before we have been reimbursed by our tenants. This exposes us to additional risks of collection in the event of a bankruptcy, insolvency, or a condominium purchaser default. The reverse can occur as well, where a contractor we have paid files for bankruptcy protection or commits fraud with the funds before completing a project that we have funded in part or in full.

Additionally, we may use partnerships and limited liability companies to develop some of our real estate investments. Acting through our wholly owned subsidiaries, we typically will be the general partner or managing member in these partnerships or limited liability companies. There are, however, instances in which we may not control or even participate in management or day-to-day operations of these properties. The use of partnerships and limited liability companies involve special risks associated with the possibility that:

7

Table of Contents

In the event any of our partners or members file for bankruptcy, we could be precluded from taking certain actions affecting our project without bankruptcy court approval, which could diminish our control over the project even if we were the general partner or managing member. In addition, if the bankruptcy court were to discharge the obligations of our partner or member, it could result in our ultimate liability for the project being greater than originally anticipated.

Further, disputes between us and a partner may result in litigation or arbitration that may increase our expenses and prevent our management from focusing their time and attention on our business.

To the extent we are a general partner, we may be exposed to unlimited liability, which may exceed our investment or equity in the partnership. If one of our subsidiaries is a general partner of a particular partnership, it may be exposed to the same kind of unlimited liability.

Development of properties may entail a lengthy, uncertain, and costly entitlement process.

Approval to develop real property sometimes requires political support and generally entails an extensive entitlement process involving multiple and overlapping regulatory jurisdictions and often requires discretionary action by local governments. Real estate projects must generally comply with local land development regulations and may need to comply with state and federal regulations. We may incur substantial costs to comply with legal and regulatory requirements. An increase in legal and regulatory requirements may cause us to incur substantial additional costs, or in some cases cause us to determine that the property is not feasible for development. In addition, our competitors and local residents may challenge our efforts to obtain entitlements and permits for the development of properties. The process to comply with these regulations is usually lengthy and costly, may not result in the approvals we seek, and can be expected to materially affect our development activities.

Government regulations and legal challenges may delay the start or completion of the development of our communities, increase at a rate greater thanour expenses or limit our building of apartments or other activities.

Various local, state, and federal statutes, ordinances, rules, and regulations concerning building, health and safety, site and building design, environment, zoning, sales, and similar matters apply to or affect the real estate development industry. In addition, our ability to increase rents,obtain or renew permits or approvals and the continued effectiveness of permits already granted or approvals already obtained depends on factors beyond our control, such as changes in federal, state, and local policies, rules and regulations, and their interpretations and application.

Municipalities may restrict or place moratoriums on the availability of utilities, such as water and sewer taps. If municipalities in which we can only do upon renewal of existing leasesoperate take such actions, it could have an adverse effect on our business by causing delays, increasing our costs, or at the inception of new leases;

Our apartment communities compete for residents with other housing alternatives, including other rental apartments and condominiums, and, to a lesser degree, single-family homes that are available for rent, as well as new and existing condominiums and single-family homes for sale. Competitive residential housing, as well as household formation and job creation in a particular area, could adversely affect our ability to lease apartment homes and to increase or maintain rental rates.

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

Various federal, state, and local laws subject apartment communityreal estate owners or operators to liability for management, and the costs of removal or remediation of certain potentially hazardous materials that may be present in the land or buildings of an apartment community.buildings. Potentially hazardous materials may include polychlorinated biphenyls, petroleum-based fuels, lead-based paint, or asbestos, among other materials. Such laws often impose liability without regard to fault or whether the owner or operator

Under the Americans with Disabilities Act of 1990 or ADA,(“ADA”), all places intended to be used by the public are required to meet certain federal requirements related to access and use by disabled persons. The Fair Housing Amendments Act of 1988 or FHAA,(“FHAA”), requires apartment communities first occupied after March 13, 1991, to comply with design and construction requirements for disabled access. For those apartment communities receiving federal funds, the Rehabilitation Act of 1973 also has requirements regarding disabled access. These and other federal, state, and local laws may require structural modifications to our apartment communities or changes in policy/practice, or affect renovations of the communities. Noncompliance with these laws could result in the imposition of fines or an award of damages to private litigants and also could result in an order to correct any non-complying feature, which could result in substantial capital expenditures. Although we believe that our apartment communities are substantially in compliance with present requirements, we may incur unanticipated expenses to comply with the ADA, the FHAA, and the Rehabilitation Act of 1973 in connection with the ongoing operation or redevelopment of our apartment communities.

Although we are proactively engaged in managing moisture intrusion and preventing the presence of mold at our apartment communities, it is not unusual for periodic moisture intrusion to cause mold in isolated locations within an apartment community. We have implemented policies, procedures, and training, and include a detailed moisture intrusion and mold assessment during acquisition due diligence. We believe these measures will manage mold exposure at our apartment communities and will minimize the effects that mold may have on our residents. To date, we have not incurred any material costs or liabilities relating to claims of mold exposure or to abate mold conditions. We have only limited insurance coverage for property damage claims arising from the presence of mold and for personal injury claims related to mold exposure.

We are insured for a portion of our consolidated apartment communities’real estate assets’ exposure to casualty losses resulting from fire, earthquake, hurricane, tornado, flood, and other perils, which insurance is subject to deductibles and self-insurance retention. We recognize casualty losses or gains based on the net book value of the affected apartment communityasset and the amount of any related insurance proceeds. In many instances, the actual cost to repair or replace the apartment community may exceed its net book value and any insurance proceeds. We recognize the uninsured portion of losses as casualty losses in the periods in which they are incurred. In addition, we are self-insured for a portion of our exposure to third-party claims related to our employee health insurance plans, workers’ compensation coverage, and general liability exposure. With respect to our exposure to claims of third parties, we establish reserves at levels that reflect our known and estimated losses. The ultimate cost of losses and the impact of unforeseen events

may vary materially from recorded reserves, and variances may adversely affect our operating results and financial condition. We purchase insurance to reduce our exposure to losses and limit our financial losses on large individual risks. The availability and cost of insurance are determined by market conditions outside our control. No assurance can be made that we will be able to obtain and maintain insurance at the same levels and on the same terms as we do today. If we are not able to obtain or maintain insurance in amounts, we consider appropriate for our business, or if the cost of obtaining such insurance increases materially, we may have to retain a larger portion of the potential loss associated with our exposures to risks.

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

Members of talent on which to draw. However, there are no assurances that we would be able to find qualified replacements for the individuals who make up our senior management if their services were no longer available.team have national or regional industry reputations that attract business and investment opportunities and assist us in negotiations with lenders, existing and potential tenants, and other industry participants. The loss of services of one or more members of our senior management team, or our inability to attract and retain similarly qualified personnel, could adversely affect our business, diminish our investment opportunities, and weaken our relationships with lenders, business partners, existing and prospective tenants, and industry participants, which could adversely affect our financial condition, results of operations, and cash flow.

We rely on AIR to manage a majority of our properties. If AIR fails to efficiently manage such properties, tenants may not renew their leases, or we may become subject to unforeseen liabilities.

A majority of our properties are managed by AIR. We do not supervise AIR or its managers and employees on a day-to-day basis and we cannot assure you that they will manage such properties in a manner that is consistent with their obligations under our agreements, that they will not be negligent in their performance or engage in any criminal or fraudulent activity, or that they will not otherwise default on their management obligations to us. If any of the foregoing occurs, the relationships with our tenants at such properties could be damaged, which may cause the tenants not to renew their leases, and we could incur liabilities resulting from loss or injury to the properties or to persons at the properties. If we are unable to lease the properties or we become subject to significant liabilities as a result of AIR’s management performance, our financial condition and results of operations could be substantially harmed.

In addition to property management services, we depend on AIR to support certain of our property’s operations, and any adverse changes in the financial health of AIR or our relationship with it could hinder AIR’s ability to successfully manage our operations.

We are dependent on AIR to support certain of our property’s operations pursuant to the Property Management Agreement. Any adverse changes in the financial condition of AIR, AIR’s ability to retain or replace its employees, or our relationship with AIR, could hinder AIR’s ability to successfully manage our operations, which would materially adversely affect our financial condition and results of operations.

Our business and operations would suffer in the event of significant disruptions or cyberattacks of our information technology systems or our failure to comply with laws, rules and regulations related to privacy and data protection.

Information technology, communication networks, and related systems are essential to the operation of our business. We use these systems to manage our vendor relationships, internal communications, accounting and record-keeping systems, and many other key aspects of our business. Our operations rely on the secure processing, storage, and transmission of confidential and other information in our computer systems and networks, which also depend on the strength of our procedures and the effectiveness of our internal controls. Information security risks have generally increased in recent years due to the rise in new technologies and the increased sophistication and activities of perpetrators of cyberattacks.

Despite system redundancy, risk transfer, insurance, indemnification, the implementation of security measures, required employee awareness training, and the existence of a disaster recovery plan for our internal information technology systems, our systems, and systems maintained by third-party vendors with which we do business are vulnerable to damage from any number

11

of sources. We face risks associated with energy blackouts, natural disasters, terrorism, war, telecommunication failures, and cyberattacks and intrusions, such as computer viruses, malware, attachments to emails, intrusion, and unauthorized access, including from persons inside our organization or from persons outside our organization with access to our systems. We may also incur additional costs to remedy damages caused by such disruptions. Although we make efforts to maintain the security and integrity of our systems and have implemented various measures to manage the risk of a security breach or disruption, there can be no assurance that our security efforts and measures will be effective or that attempted security breaches or disruptions would not be successful or damaging. Any compromise of our security could also result in a violation of applicable privacy and other laws, significant legal and financial exposure, damage to our reputation, loss or misuse of the information (which may be confidential, proprietary, or commercially sensitive in nature), and a loss of confidence in our security measures, which could harm our business.

We also are subject to laws, rules, and regulations in the United States, such as the California Consumer Protection Act (the “CCPA” (which became effective on January 1, 2020)), relating to the collection, use, and security of employee and other data. Evolving compliance and operational requirements under the CCPA and the privacy and data security laws of other jurisdictions in which we operate impose significant costs that are likely to increase over time. Our failure to comply with laws, rules, and regulations related to privacy and data protection could harm our business or reputation.

“ROFO/Purchase Option” provisions, such as in our Master Leasing Agreement, may discourage third parties from negotiating with us with respect to the sale of our real property.

During the term of the Master Leasing Agreement, AIR will have a purchase option on the direct or indirect transfer of any real property owned or, subject to the consent of the landlord, leased by us (including indirect transfers pursuant to a transfer of equity interests in any of our subsidiaries that owns or leases such real property) and any rights to acquire real property, but excluding any property leased from AIR pursuant to the Master Leasing Agreement, with respect to real property for which redevelopment has been substantially completed by Aimco (if applicable) and that has reached a specified occupancy for a minimum time period and a right of first offer with respect to stabilized properties that Aimco is under contract to purchase, but excluding any such transfers in respect of certain of the operating properties. This right of first offer and purchase option may discourage third parties from negotiation with us with respect to the sale of our real property and may limit the number of interested buyers, and further may prevent us from receiving the maximum price that we may otherwise have obtained for such properties.

There may be, or there may be the appearance of, conflicts of interest in our relationship with AIR.

There may be, or there may be the appearance of, conflicts of interest in our relationship with AIR. The Separation was designed to minimize conflicts of interest between us and AIR, however, there can be no assurance that such conflicts don’t exist.

Although we and AIR each have an independent board of directors and independent management and are incentivized to make decisions that are in the best interests of its respective business, Mr. Considine, along with Messrs. Miller and Stein, serve on both our and AIR’s boards of directors, however, such directors will recuse themselves from voting as members of either board of directors during the approval or disapproval of any transactions between the two companies.

The agreements between us and AIR generally do not limit or restrict AIR or its affiliates from engaging in any business or managing other entities that engage in business of the type conducted by us. Although we and AIR do not generally engage in the same business, AIR and its affiliates may in the future determine to redevelop or develop apartment communities and other real estate assets, some of which may be in close proximity to certain of our apartment communities. Certain business opportunities appropriate for us may also in the future be appropriate for AIR or its affiliates, and we may compete with AIR for certain business opportunities. This may cause us to compete with AIR for business opportunities or result in a change in our current business strategy.

Actual, potential, or perceived conflicts could give rise to investor dissatisfaction, settlements with stockholders, litigation or regulatory inquiries or enforcement actions. Appropriately dealing with conflicts of interest is complex and difficult, and our reputation could be damaged if we fail, or appear to fail, to deal appropriately with one or more potential, actual, or perceived conflicts of interest. Regulatory scrutiny of, or litigation in connection with, conflicts of interest could have a material adverse effect on our reputation, which could materially adversely affect our business in a number of ways, including causing a reluctance of counterparties to do business with us, a decrease in the prices of our equity securities, and a resulting increased risk of litigation and regulatory enforcement actions.

Our business could be negatively affected as a result of the actions of activist stockholders.

Publicly traded companies have increasingly become subject to campaigns by investors advocating corporate actions such as financial restructuring, increased borrowing, special dividends, stock repurchases, or even sales of assets or the entire company. Given our stockholder composition and other factors, it is possible our stockholders or future activist stockholders

12

Table of Contents

may attempt to effect such changes. Responding to proxy contests and other actions by such activist stockholders or others would be costly and time-consuming, disrupt our operations and divert the attention of our board of directors and senior management team from the pursuit of business strategies, which could adversely affect our results of operations and financial condition. Additionally, perceived uncertainties as to our future direction as a result of stockholder activism or changes to the composition of the board of directors may lead to the perception of a change in the direction of the business, instability or lack of continuity, which may be exploited by our competitors, cause concern to our current or potential lenders, partners, or others with whom we do business, and make it more difficult to attract and retain qualified personnel.

RISKS RELATED TO OUR INDEBTEDNESS AND FINANCING

Our debt financing could result in foreclosure of our apartment communities, prevent us from making distributions on our equity, or otherwise adversely affect our liquidity.

On December 16, 2020, we entered into a new revolving secured credit facility. In connection with the Separation, certain of our subsidiaries retained existing secured property-level debt equal to approximately $449.5 million and another became the obligator on two notes payable to the subsidiaries of AIR with an aggregated principal amount equal to approximately $534.1 million (“Notes Payable to AIR”). Over time, we may become party to one or more additional financing arrangements, including credit facilities or other bank debt, bonds, and mortgage financing.

In connection with such financing activities, we are subject to the risk that our cash flow from operations will be insufficient to make required payments of principal and interest, and the risk that our indebtedness may not be refinanced or that the terms of any refinancing will not be as favorable as the terms of then-existing indebtedness. If we fail to make required payments of principal and interest on our non-recourse debt, our lenders could foreclose on the apartment communities and other collateral securing such debt, which would result in the loss to us of income and asset value. As of December 31, 2020, a significant number of our apartment communities are encumbered by property debt or serve as collateral for the Notes Payable to AIR. Our organizational documents do not limit the amount of debt that we may incur, and we have significant amounts of debt outstanding. Payments of principal and interest may leave us with insufficient cash resources to operate our communities or pay distributions required to maintain our qualification as a REIT.

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

Our ability to obtain financing and the cost of such financing depends on the overall condition of the United States credit markets. During periods of economic uncertainty, the United States credit markets may experience significant liquidity disruptions, which may cause the spreads on debt financings to widen considerably and make obtaining financing, both non-recourse property debt and corporate borrowings such as those under our credit facilities, more difficult. In particular, apartment borrowers have benefited from the historic willingness of the Federal National Mortgage Association (“Fannie Mae”), and the Federal Home Loan Mortgage Corporation (“Freddie Mac”), to make substantial amounts of loans secured by multifamily properties, even in times of economic distress. These two lenders are federally chartered and subject to federal regulation, which is subject to change, making uncertain their prospects and ability to provide liquidity in a future downturn.

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

Increases in interest rates would increase our interest expense and reduce our profitability, and the potential phasing out of LIBOR after 2021 may affect our financial results.

Our new revolving secured credit facility contains variable-rate interest and may be based, in part, on LIBOR. An increase or decrease in LIBOR would likely increase or decrease our interest expense. An increase in interest expense may affect our profitability.

In addition, in July 2017, the Financial Conduct Authority, which regulates LIBOR, announced it intends to stop compelling banks to submit rates for the calculation of LIBOR after 2021. In 2018, the Alternative Reference Rates Committee identified the Secured Overnight Financing Rate (“SOFR”), as the alternative to LIBOR. Whether or not SOFR attains market traction as a LIBOR replacement remains a question, and the future of LIBOR at this time is uncertain. At this time, it is not possible to predict the effect of any such changes, any establishment of alternative reference rates or any other reforms to LIBOR that may be enacted in the United Kingdom or elsewhere. Due to the broad use of LIBOR as a reference rate, all financial market participants, including us, are impacted by the risks associated with this transition. To the extent any of our new revolving secured credit facility is expected to have a variable-rate interest based, in part, on LIBOR and, if LIBOR is no longer available, an alternative benchmark index will likely be proposed to replace it. Accordingly, any of these proposals or the resulting consequences could have a material adverse effect on our financing costs, and as a result, our financial condition, operating results, and cash flows.

Covenant restrictions may limit our operations and impact our ability to make payments to our investors.

Some of our existing and/or future debt and other securities may contain covenants that restrict our activities. These may include covenants that limit our operations or impact our ability to make distributions or other payments unless certain financial tests or other criteria are satisfied, as well as certain other customary affirmative and negative covenants.

We may increase leverage in executing our development plan, which could further exacerbate the risks associated with our substantial indebtedness.

We may decide to increase our leverage to execute our development plan. We will consider a number of factors when evaluating our level of indebtedness and when making decisions regarding the incurrence of new indebtedness, including the estimated market value of our assets and the ability of particular assets, and our company as a whole, to generate cash flow to cover the expected debt service. Although our credit facilities may limit our ability to incur additional indebtedness, our governing documents do not limit the amount of debt we may incur, and we may change our target debt levels at any time without the approval of our stockholders. We may incur additional indebtedness from time to time in the future to finance working capital, capital expenditures, investments or acquisitions, or for other purposes. If we do so, the risks related to our indebtedness could intensify.

RISKS RELATED TO THE SEPARATION

We may be unable to achieve some or all of the benefits that we expect to achieve from the Separation.

Following the Separation, we and AIR are two, focused and independent companies. We may not be able to achieve some or all of the benefits that we expect to achieve as a company independent from AIR in the time we expect, if at all. For instance, it may take longer than anticipated for us to, or we may never, succeed in growing our revenues through our development and redevelopment business.

The Separation could give rise to disputes or other unfavorable effects, which could materially and adversely affect our business, financial condition andposition or results of operations.

In connection with the Separation, we entered into a Separation and Distribution Agreement with AIR, effective as of December 15, 2020 (the “Separation Agreement”), which, among other things, contains the agreements among the parties regarding the principal transactions necessary to effect the Separation. It also sets forth other agreements that govern certain aspects of the parties’ ongoing relationship after the completion of the Separation. The Separation may lead to increased operating and other expenses, of both a nonrecurring and a recurring nature, and to changes to certain operations, which expenses or changes could arise pursuant to arrangements made between AIR and us or could trigger contractual rights of, and obligations to, third parties. Disputes with third parties could also arise out of these transactions, and we could experience unfavorable reactions to the Separation from employees, lenders, ratings agencies, regulators, OP unitholders or other interested parties. These increased expenses, changes to operations, disputes with third parties or other effects could materially and adversely affect our business, financial position or results of operations. In addition, following the Separation, disputes with AIR could arise in connection with each of the Separation Agreement, the Employee Matters Agreement, the Property Management Agreements, the Master Services Agreement, the Master Leasing Agreement, or certain other agreements.

Although we have endeavored to enter into agreements on market terms, our agreements with AIR may not reflect terms that would have resulted from arm’s-length negotiations with unaffiliated third parties.

The agreements related to the Separation, including the Separation Agreement, the Employee Matters Agreement, the Property Management Agreements, the Master Services Agreement, the Master Leasing Agreement, and certain other agreements were entered into in the context of the Separation while both companies were under common control. As a result, although we endeavored to enter into these agreements on market terms, they may not reflect terms that would have resulted from arm’s-length negotiations between unaffiliated third parties. The terms of the agreements entered into in the context of the Separation concern, among other things, allocation of assets and liabilities attributable to periods prior to the Separation and the rights and obligations, including certain indemnification obligations, of AIR and us after the Separation, certain services provided by us to AIR and by AIR to us after the Separation, and our lease from AIR of the Initial Leased Properties.

Following the Separation, we may be unable to make, on a timely or cost-effective basis, the changes necessary to operate as an independent company.

Following the Separation, AIR hired substantially all of Aimco’s existing employees (including Aimco’s existing property management employees), and Aimco retained approximately 50 employees. We dohave no significant historical operations as a company independent from AIR and did not, currently maintain key-man life insurancefollowing the Separation, have the infrastructure or personnel necessary to operate as an independent company without relying on AIR to provide certain services (such as those related to technology, payroll, etc.) on an ongoing basis. In connection with the Separation, we entered into a Master Services Agreement with AIR pursuant to which AIR will provide certain services to us to allow us to benefit from certain cost efficiencies in sharing certain resources

and personnel. As a separate publicly traded company, Aimco is subject to, and responsible for, anyregulatory compliance, including periodic public filings with the SEC and compliance with the NYSE continued listing requirements as well as compliance with generally applicable tax and accounting rules, certain elements of which may rely on services provided by AIR under the Master Services Agreement.

If Aimco fails to qualify as a REIT, Aimco will not be allowed a deduction for dividends paid to its stockholders in computing its taxable income and will be subject to United States federal income tax at regular corporate rates. This would substantially reduce our funds available for general corporate usage or for distribution to our investors. Unless entitled to relief under certain provisions of the Code, Aimco also would be disqualified from taxation as a REIT for the four taxable years following the year during which it ceased to qualify as a REIT. In addition, Aimco’s failure to qualify as a REIT wouldmay place us in default under our revolving credit agreement.

We believe that Aimco operates, and has since its taxable year ended December 31, 1994, operated, in a manner that enables it to meet the requirements for qualification and taxation as a REIT. However, qualification as a REIT involves the application of highly technical and complex Code provisions for United States federal income tax purposes.which only limited judicial and administrative authorities exist. Moreover, even a technical or inadvertent mistake could jeopardize our REIT status. Aimco’s continued qualification as a REIT will depend on its satisfaction of certain asset, income, investment, organizational, distribution, stockholder ownership, and other requirements on a continuing basis. Aimco’s ability to satisfy the asset tests depends upon our analysis of the fair market values of our assets, some of which are not susceptible to a precise determination, and for which we do not obtain independent appraisals. Aimco’s compliance with the REIT annual income and quarterly asset requirements also depends upon our ability to successfully manage successfully the composition of our income and assets on an ongoing basis. Moreover, the proper classification of an instrument as debt or equity for United StatesU.S. federal income tax purposes may be uncertain in some circumstances, which could affect the application of the REIT qualification requirements. Accordingly, there can be no assurance that the Internal Revenue Service or the IRS,(the “IRS”), will not contend that our interests in subsidiaries or other issuers constitutes a violation of the REIT requirements. Moreover, future economic, market, legal, tax, or other considerations may cause Aimco to fail to qualify as a REIT, or Aimco’s Boardthe board of Directorsdirectors of Aimco may determine to revoke its REIT status.

As a REIT, Aimco is subject to annual distribution requirements. The Aimco Operating Partnership pays distributions, including taxable stock dividends, intended to enable Aimco to satisfy its distribution requirements. This limits the amount of cash available for other business purposes, including amounts to fund our growth. Aimco generally must distribute annually at least 90% of its REIT“real estate investment trust taxable income,” which is generally equivalent to net taxable ordinary income, determined without regard to the dividends paid deduction and excluding any net capital gain, in order for its distributed earnings not to be subject to United States federal corporate income tax. We intend to make distributions to Aimco’s stockholders to comply with the requirements applicable to REITs under the Code (which may be all cash or combination of cash and stock satisfying the Code.requirements of applicable law). However, differences in timing between the recognition of taxable income and the actual receipt of cash could require us to sell apartment communities or borrow funds on a short-term or long-term basis to meet the 90% distribution requirement of the Code.

In addition, Aimco Operating Partnership may issue an unlimited number of residents to those with incomes atadditional OP Units or below certain levels. Failure to comply with these requirementsother securities for such consideration and on such terms as it may result in financial penalties or loss of benefits. We are usually required to obtainestablish, without the approval of HUDthe holders of OP Units. Such securities could have priority over the OP Units as to cash flow, distributions, and liquidation proceeds. The effect of any such issuance may be to dilute the interests of holders of OP Units.

Cash distributions by Aimco Operating Partnership are not guaranteed and may fluctuate with partnership performance.

Aimco Operating Partnership does not intend to make regular distributions to holders of OP Units (other than what is required for Aimco to maintain its REIT status). There can be no assurance regarding the amounts of available cash that Aimco Operating Partnership will generate or the portion that its general partner will choose to distribute. The actual amounts of available cash will depend upon numerous factors, including profitability of operations, required principal and interest payments on its debt, the cost of acquisitions (including related debt service payments), its issuance of debt and equity securities, fluctuations in order to acquire or disposeworking capital, capital expenditures, adjustments in reserves, prevailing economic conditions, and financial, business, and other factors, some of a significant interest in or manage a HUD-assisted apartment community. Wewhich may be beyond Aimco Operating Partnership’s control. Cash distributions depend primarily on cash flow, including from reserves, and not on profitability, which is affected by non-cash items. Therefore, cash distributions may be made during periods when the Aimco Operating Partnership records losses and may not always receive such approval.

Aimco may purchasehave conflicts of interest with holders of OP Units.

Conflicts of interest could arise in the shares of capital stock held in trust at a price equal to the lesser of the price paid by the transferee of the shares or the then current market price. If the trust transfers any of the shares of capital stock, the affected person will receive the lesser of the price paid for the shares or the then current market price. An individual who acquires shares of capital stock that violate the above rules bears the risk that the individual:

The Aimco Operating Partnership agreement limits the liability of the general partner for actions taken in good faith. Aimco Operating Partnership’s partnership agreement expressly limits the liability of the general partner by providing that the general partner, and its officers and directors, will not be liable or accountable in damages to Aimco Operating Partnership, the limited partners, or assignees for errors in judgment or mistakes of fact or law or of any act or omission if the general partner or such director or officer acted in good faith. In addition, Aimco Operating Partnership is required to indemnify the general partner, its affiliates, and their respective officers, directors, employees, and agents to the fullest extent permitted by applicable law, against any and all losses, claims, damages, liabilities, joint or several, expenses, judgments, fines, and other actions incurred by the general partner or such other persons, provided that Aimco Operating Partnership will not indemnify for (i) willful misconduct or a knowing violation of the law or (ii) for any transaction for which such person received an improper personal benefit in violation or breach of any provision of the partnership agreement. The provisions of Delaware law that allow the common law fiduciary duties of a general partner to be modified by a partnership agreement have not been resolved in a court of law, and the general partner has not obtained an opinion of counsel covering the provisions set forth in the Aimco Operating Partnership agreement that purport to waive or restrict the fiduciary duties of the general partner that would be in effect under common law were it not for the partnership agreement.
