EXPLANATORY NOTE 

This filing combines the Annual Reports on Form 10-K for the fiscal year ended December 31, 2017, of Apartment Investment and Management 
Company,  or  Aimco,  and  AIMCO  Properties,  L.P.,  or  the  Aimco  Operating  Partnership.  Where  it  is  important  to  distinguish  between  the  two 
entities, we refer to them specifically. Otherwise, references to “we,” “us” or “our” mean collectively Aimco, the Aimco Operating Partnership and 
their consolidated entities.  

Aimco, a Maryland corporation, is a self-administered and self-managed real estate investment trust, or REIT. Aimco, through wholly-owned 
subsidiaries, is the general and special limited partner of and, as of December 31, 2017, owned a 95.5% ownership interest in the common partnership 
units  of,  the  Aimco  Operating  Partnership.  The  remaining  4.5%  interest  is  owned  by  limited  partners.  As  the  sole  general  partner  of  the  Aimco 
Operating Partnership, Aimco has exclusive control of the Aimco Operating Partnership’s day-to-day management. 

The Aimco Operating Partnership holds all of Aimco’s assets and manages the daily operations of Aimco’s business. Pursuant to the Aimco 
Operating Partnership agreement, Aimco is required to contribute to the Aimco Operating Partnership any assets which it may acquire including all 
proceeds from the offerings of its securities. In exchange for the contribution of these assets, Aimco receives additional interests in the Aimco 
Operating  Partnership  with  similar  terms  (e.g.,  if  Aimco  contributes  proceeds  of  a  stock  offering,  Aimco  receives  partnership  units  with  terms 
substantially similar to the stock issued by Aimco). 

We  believe  combining  the  periodic  reports  of  Aimco  and  the  Aimco  Operating  Partnership  into  this  single  report  provides  the  following 

benefits:  

•  We present our business as a whole, in the same manner our management views and operates the business;

•  We  eliminate  duplicative  disclosure  and  provide  a  more  streamlined  and  readable  presentation  because  a  substantial  portion  of  the 

disclosures apply to both Aimco and the Aimco Operating Partnership; and  

•  We save time and cost through the preparation of a single combined report rather than two separate reports.

We operate Aimco and the Aimco Operating Partnership as one enterprise, the management of Aimco directs the management and operations 
of the Aimco Operating Partnership, and the members of the Board of Directors of Aimco are identical to those of the Aimco Operating Partnership. 

We believe it is important to understand the few differences between Aimco and the Aimco Operating Partnership in the context of how Aimco 
and the Aimco Operating Partnership operate as a consolidated company. Aimco has no assets or liabilities other than its investment in the Aimco 
Operating Partnership. Also, Aimco is a corporation that issues publicly traded equity from time to time, whereas the Aimco Operating Partnership 
is a partnership that has no publicly traded equity. Except for the net proceeds from stock offerings by Aimco, which are contributed to the Aimco 
Operating Partnership in exchange for additional limited partnership interests (of a similar type and in an amount equal to the shares of stock sold in 
the offering), the Aimco Operating Partnership generates all remaining capital required by its business. These sources include the Aimco Operating 
Partnership’s working capital, net cash provided by operating activities, borrowings under its revolving credit facility, the issuance of debt and 
equity securities, including additional partnership units, and proceeds received from the sale of apartment communities.  

Equity, partners’ capital and noncontrolling interests are the main areas of difference between the consolidated financial statements of Aimco 
and those of the Aimco Operating Partnership. Interests in the Aimco Operating Partnership held by entities other than Aimco, which we refer to as 
OP  Units,  are  classified  within  partners’  capital  in  the  Aimco  Operating  Partnership’s  financial  statements  and  as  noncontrolling  interests  in 
Aimco’s financial statements.  

To help investors understand the differences between Aimco and the Aimco Operating Partnership, this report provides separate consolidated 
financial statements for Aimco and the Aimco Operating Partnership; a single set of consolidated notes to such financial statements that includes 
separate  discussions  of  each  entity’s  stockholders’  equity  or  partners’  capital,  as  applicable;  and  a  combined  Management’s  Discussion  and 
Analysis of Financial Condition and Results of Operations section that includes discrete information related to each entity.  

This report also includes separate Part II, Item 9A. Controls and Procedures sections and separate Exhibits 31 and 32 certifications for Aimco 
and the Aimco Operating Partnership in order to establish that the requisite certifications have been made and that Aimco and the Aimco Operating 
Partnership are both compliant with Rule 13a-15 or Rule 15d-15 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and 18 
U.S.C. §1350.

FORWARD-LOOKING STATEMENTS 

The  Private  Securities  Litigation  Reform  Act  of  1995  provides  a  “safe  harbor”  for  forward-looking  statements  in  certain  circumstances. 
Certain  information  included  in  this  Annual  Report  contains  or  may  contain  information  that  is  forward-looking,  within  the  meaning  of  the 
federal securities laws, including, without limitation, statements regarding: our ability to maintain current or meet projected occupancy, rental 
rates and property operating results; the effect of acquisitions, dispositions, redevelopments and developments; our ability to meet budgeted 
costs and timelines, and achieve budgeted rental rates related to our redevelopment and development investments; expectations regarding sales 
of  our  apartment  communities  and  the  use  of  proceeds  thereof;  and  our  ability  to  comply  with  debt  covenants,  including  financial  coverage 
ratios.  

Actual results may differ materially from those described in these forward-looking statements and, in addition, will be affected by a variety of 

risks and factors, some of which are beyond our control, including, without limitation:  

•  Real estate and operating risks, including fluctuations in real estate values and the general economic climate in the markets in which we 
operate and competition for residents in such markets; national and local economic conditions, including the pace of job growth and the 
level  of  unemployment;  the  amount,  location  and  quality  of  competitive  new  housing  supply;  the  timing  of  acquisitions,  dispositions, 
redevelopments and developments; and changes in operating costs, including energy costs; 

• 

• 

• 

Financing risks, including the availability and cost of capital markets’ financing; the risk that our cash flows from operations may be 
insufficient  to  meet  required  payments  of  principal  and  interest;  and  the  risk  that  our  earnings  may  not  be  sufficient  to  maintain 
compliance with debt covenants;  

Insurance risks, including the cost of insurance, natural disasters and severe weather such as hurricanes; and 

Legal  and  regulatory  risks,  including  costs  associated  with  prosecuting  or  defending  claims  and  any  adverse  outcomes;  the  terms  of 
governmental regulations that affect us and interpretations of those regulations; and possible environmental liabilities, including costs, 
fines or penalties that may be incurred due to necessary remediation of contamination of apartment communities presently or previously 
owned by us. 

In  addition,  our  current  and  continuing  qualification  as  a  real  estate  investment  trust  involves  the  application  of  highly  technical  and 
complex provisions of the Internal Revenue Code and depends on our ability to meet the various requirements imposed by the Internal Revenue 
Code, through actual operating results, distribution levels and diversity of stock ownership. 

Readers should carefully review our financial statements and the notes thereto, as well as the section entitled “Risk Factors” described in 

Item 1A of this Annual Report and the other documents we file from time to time with the Securities and Exchange Commission. 

PART I 

Item 1. Business 

The Company 

Apartment  Investment  and  Management  Company,  or  Aimco,  is  a  Maryland  corporation  incorporated  on  January  10,  1994.  Aimco  is  a  self-
administered  and  self-managed  real  estate  investment  trust,  or  REIT,  focused  on  the  ownership,  management,  redevelopment  and  limited 
development of quality apartment communities located in some of the largest markets in the United States.  

Aimco, through its wholly-owned subsidiaries, AIMCO-GP, Inc. and AIMCO-LP Trust, owns a majority of the ownership interests in AIMCO 
Properties, L.P., or the Aimco Operating Partnership, a Delaware limited partnership formed on May 16, 1994. Aimco conducts all of its business and 
owns all of its assets through the Aimco Operating Partnership. 

As of December 31, 2017, we had ownership interests in 182 apartment communities with 43,802 apartment homes. 

Business Overview 

Our  business  activities  are  defined  by  a  commitment  to  our  core  values  of  integrity,  respect,  collaboration,  performance  and  a  focus  on  our 
customers. These values and our corporate mission, “to consistently provide quality apartment homes in a respectful environment delivered by a 
team of people who care,” shape our culture. In all of our interactions with residents, team members, business partners, lenders, and equity holders, 
we aim to be the best owner and operator of apartment communities and an outstanding corporate citizen. 

2 

 
 
 
Table of Contents 

Our  principal  financial  objective  is  to  provide  predictable  and  attractive  returns  to  our  equity  holders.  We  measure  our  current  return  using 
Adjusted Funds From Operations and our long-term return using Economic Income (each of which are defined under the Non-GAAP Measures 
heading in Item 7). Our business plan to achieve this principal financial objective is to:  

• 

• 

• 

operate our portfolio of desirable apartment homes with a high level of focus on customer selection and customer satisfaction and in an 
efficient manner that produces predictable and growing Free Cash Flow, which is defined under the Operational Excellence heading, below;  

improve  our  portfolio  of  apartment  communities,  which  is  diversified  both  by  geography  and  by  price  point  by  selling  apartment 
communities  with  lower  projected  free  cash  flow  internal  rates  of  return  and  investing  the  proceeds  from  such  sales  through  capital 
enhancements, redevelopment, development, and acquisitions with greater land value, higher expected rent growth, and projected free cash 
flow internal rates of return in excess of those expected from the communities sold;  

use low levels of financial leverage primarily in the form of non-recourse, long-dated, fixed-rate property debt and perpetual preferred equity, 
a combination which reduces our refunding and re-pricing risk and which provides a hedge against increases in interest rates; and 

• 

focus intentionally on a collaborative and productive culture based on respect for others and personal responsibility.

Our business is organized around five areas of strategic focus: operational excellence; redevelopment; portfolio management; balance sheet; and 
team and culture. Our areas of strategic focus are described in more detail below. Recent accomplishments in the execution of such strategies are 
discussed in the Executive Overview in Item 7. 

Operational Excellence 

We own and operate a portfolio of market rate apartment communities diversified by both geography and price point, which we refer to as our 
Real Estate portfolio. At December 31, 2017, our Real Estate portfolio included 136 apartment communities with 36,904 apartment homes in which we 
held  an  average  ownership  of 99%.  This  portfolio  was  divided  about  two  thirds by value to our  “Same  Store” portfolio  of  stabilized  apartment 
communities  and  about  one  third  by  value  to  “Other  Real  Estate,”  which  includes  recently  acquired  communities  and  communities  under 
redevelopment or development whose long-term financial contribution is not yet stabilized. 

We  also  held  nominal  ownership  positions  in  partnerships  that  own  46  low-income  housing  tax  credit  apartment  communities  with  6,898 
apartment  homes.  We  provide  services  to  these  partnerships  and  receive  fees  and  other  payments  in  return.  Our  relationship  with  these 
partnerships is different than real estate ownership and is better described as an asset management business, or Asset Management. 

To manage our property operations efficiently and to increase the benefits from our local management expertise, we give direct responsibility for 
operations within each area to area operations leaders with regular oversight by senior management. To enable the area operations leaders to focus 
on sales and service, as well as to improve financial control and budgeting, we have dedicated area financial officers who support the operations 
leaders.  Additionally,  with  the  exception  of  routine  maintenance  and  purchases  and  installation  of  equipment,  we  have  specialized  teams  that 
manage capital spending related to larger and more complicated construction.  

We  seek  to  improve  our  property  operations  by:  employing  service-oriented,  well-trained  team  members;  taking  advantage  of  advances  in 
technology;  centralizing  operational  tasks  where  efficient  to  do  so;  standardizing  business  processes,  operational  measurements,  and  internal 
reporting; and enhancing financial controls over field operations. We focus on the following areas: 

•  Customer Satisfaction. Our operating culture is focused on our residents and providing them with a high level of service in a clean, safe, 
and  respectful  living  environment.  We  regularly  monitor  and  evaluate  our  performance  by  providing  customers  with  numerous 
opportunities to grade our work. In 2017, we received 84,000 customer grades averaging 4.25 on a five-point scale. We use this customer 
feedback  as  a  daily  management  tool.  We  also  publish  on-line  these  customer  evaluations  as  important  and  credible  information  for 
prospective customers. We have automated certain aspects of our on-site operations to enable current and future residents to interact with 
us using methods that are efficient and effective for them, such as making on-line requests for service work and executing leases and lease 
renewals on-line. In addition, we emphasize the quality of our on-site team members through recruiting, training and retention programs, 
which,  with  the  continuous,  real-time  customer  feedback,  contributes  to  improved  customer  service.  We  believe  that  greater  customer 
satisfaction leads to higher resident retention and increased occupancy rates, which in turn leads to increased revenue and reduced costs. 

• 

Resident Selection and Retention. In our apartment communities, we believe that one’s neighbors are a meaningful part of the customer 
experience, together with the location of the community and the physical quality of the apartment homes.  

3 

 
 
Table of Contents 

Part of our property operations strategy is to focus on attracting and retaining stable, credit-worthy residents who are also good neighbors. 
We have explicit criteria for resident selection, which we apply to new leases and to renewal leases, including creditworthiness and behavior 
in accordance with our community standards and our written “Good Neighbor Commitment.” Our focus on resident selection and retention 
led to 53% of expiring leases being renewed in 2017, which is above peer average.  

•  Revenue Management and Ancillary Services. We have a centralized revenue management system that leverages people, processes, and 
technology to work in partnership with our local property management teams to develop rental rate pricing. We seek to increase Free Cash 
Flow, which we define as net operating income less Capital Replacements, by optimizing the balance between rental and occupancy rates, as 
well as taking into consideration costs such as preparing an apartment home for a new resident. We are focused on careful measurements of 
on-site  operations,  as  we  believe  that  timely  and  accurate  collection  of  apartment  community  performance  and  resident  profile  data  will 
enable us to maximize Free Cash Flow through better property management and leasing decisions. We seek to maximize profit by performing 
timely data analysis of new and renewal pricing for each apartment home, thereby enabling us to adjust rents quickly in response to changes 
in supply and demand and minimize vacancy time. We also generate incremental revenue by providing services to our residents, including, at 
certain apartment communities, telecommunications services, parking options, package lockers, and storage space rental.  

•  Controlling Expenses. Innovation is the foundation of our cost control efforts. Innovative activities include: moving administrative tasks to 
our shared service center, which reduces costs and allows site teams to focus on sales and service; taking advantage of economies of scale 
at the corporate level, through electronic procurement which reduces complexity and increases purchasing volume discounts; focusing on 
life  cycle  costs  by  investing  in  more  durable,  longer-lived  materials,  which  reduce  turn  times  and  costs;  and  leveraging  technology  to 
enhance the customer experience through website design and package lockers, which meet today’s customer preference for self-service. For 
the year ended  December 31, 2017 compared to 2016, Same Store property operating expenses increased by  0.7%. Same Store controllable 
operating expenses, which we define as property operating expenses excluding taxes, insurance and utility expenses, decreased by 1.3%. The 
compounded annual growth rate for Same Store controllable operating expenses for the past decade is negative 0.4%. 

• 

Improving  and  Maintaining  Apartment  Community  Quality.  We  believe  that  the  physical  condition  and  amenities  of  our  apartment 
communities are important factors in our ability to maintain and increase rental rates. We invest in the maintenance and improvement of our 
apartment  communities  primarily  through:  Capital  Enhancements,  which  may  include  kitchen  and  bath  remodeling,  energy  conservation 
projects, and investments in longer-lived materials as described above, all of which are generally lesser in scope than is a redevelopment and 
do  not  significantly  disrupt  property  operations;  Capital  Improvements,  which  extend  the  useful  life  of  an  apartment  community  from  its 
condition  at  our  date  of  purchase;  and  Capital  Replacements,  which  are  capital  additions  made  to  replace  the  portion  of  an  apartment 
community consumed during our ownership. During 2017, we invested approximately $2,800 per apartment home in Capital Enhancements, 
$470 per apartment home in Capital Improvements, and $1,050 per apartment home in Capital Replacements.  

Redevelopment 

Redevelopment  is  our  second  line  of  business  where  we  create  value  equal  to  25%  to  35%  of  our  incremental  investment  by  repositioning 
communities within the Aimco portfolio and by constructing new communities. We measure the rate and quality of financial returns by Net Asset 
Value creation, an important component of Economic Income, our primary measure of long-term financial performance (Net Asset Value is defined 
under  the  Non-GAAP  Measures  heading  in  Item  7).  We  invest  to  earn  risk-adjusted  returns  in  excess  of  those  expected  from  the  apartment 
communities sold in paired trades to fund the redevelopment and development.  

We undertake a range of redevelopments, including those in which buildings or exteriors are renovated without the need to vacate apartment 
homes; those in which significant renovation of apartment homes may be accomplished upon lease expiration and turnover; and those in which an 
entire  building  or  community  is  vacated.  We  often  execute  redevelopments  using  a  phased  approach,  in  which  we  renovate  an  apartment 
community  in  stages.  Redevelopment  work  may  include  seeking  entitlements  from  local  governments,  which  enhance  the  value  of  our  existing 
portfolio by increasing density, that is, the right to add apartment homes to a site. 

We  also  undertake  ground-up  development  when  warranted  by  risk-adjusted  investment  returns,  either  directly  in  connection  with  the 
redevelopment of an existing apartment community or, on a more limited basis, at a new location. When warranted, we rely on the expertise and 
credit of a third-party developer familiar with the local market to limit our exposure to construction risk. 

Of  these  two  activities,  we  favor  redevelopment  because  it  permits  adjustment  of  the  scope  and  timing  of  spending  to  align  with  changing 

market conditions and customer preferences.

Portfolio Management 

Our portfolio management strategy involves the allocation of investment capital to enhance rent growth and increase long term capital values 
through portfolio design emphasizing land value as well as location and submarket. We target geographic diversification in our portfolio in order to 
reduce the volatility of our rental revenue and to reduce the risk of undue concentration in any particular market. Similarly, we seek price point 
diversification by owning communities that offer apartment homes at rents below those asked by competitive new building supply. 

Our portfolio of apartment communities is diversified across “A,” “B,” and “C+” price points, averaging “B/B+” in quality and is also diversified 
among  some  of  the  largest  markets  in  the  United  States.  Please  refer  to  the  Executive  Overview  heading  under  Item  7  for  a  description  of  our 
portfolio quality ratings. At December 31, 2017, our Real Estate portfolio was allocated about one half to “A” rated properties, and about one half to 
“B” and “C+” rated properties.  

As part of our portfolio strategy, we seek to sell up to 10% of our portfolio annually and to reinvest the proceeds from such sales in accretive 
uses such as capital enhancements, redevelopments, occasional developments, and selective acquisitions with projected free cash flow internal 
rates of return higher than expected from the communities being sold. Through this disciplined approach to capital recycling, we have significantly 
increased the quality and expected rental rate growth of our portfolio.  

Balance Sheet 

Our  leverage  strategy  seeks  to  increase  financial  returns  while  using  leverage  with  appropriate  caution.  We  limit  risk  through  balance  sheet 
structure, employing low leverage, primarily non-recourse and long-dated property debt; build financial flexibility by maintaining ample unused and 
available credit as well as holding properties with substantial value unencumbered by property debt; and use partners’ capital when it enhances 
financial returns or reduces investment risk. 

We  target  the  ratio  of  Proportionate  Debt  plus  Preferred  Equity  to  Adjusted  EBITDA  to  be  below  7.0x  and  we  target  the  ratio  of  Adjusted 
EBITDA to Adjusted Interest Expense and Preferred Dividends to be greater than 2.5x. Please refer to the Non-GAAP Measures heading under Item 
7 for definitions of these terms. Our leverage includes our share of long-term, non-recourse property debt secured by apartment communities in our 
Real Estate portfolio, our term loan, outstanding borrowings under our revolving credit facility, and outstanding preferred equity.  

Our liquidity consists of cash balances and available capacity on our revolving line of credit. At December 31, 2017, we had on hand $616.6 

million in cash and restricted cash plus available capacity on our line of credit.  

We also manage our financial flexibility by maintaining an investment grade rating and holding apartment communities that are unencumbered 
by property debt. At December 31, 2017, we held unencumbered apartment communities with an estimated fair market value of approximately $1.8 
billion, up 12.5% year-over year. 

Please  refer  to  the  Executive  Overview  and  Liquidity  and  Capital  Resources  headings  under  Item  7  for  additional  information  regarding  our 

balance sheet and liquidity. 

Team and Culture 

Our team and culture are keys to our success. Our intentional focus on a collaborative and productive culture based on respect for others and 
personal responsibility is reinforced by a preference for promotion from within based on succession planning and talent development to produce a 
strong, stable team that is the enduring foundation of our success. In 2017, Aimco was recognized by the Denver Post as a Top Work Place. We are 
one of only a dozen Colorado companies of all sizes that have earned this designation for five consecutive years. 

Competition 

In attracting and retaining residents to occupy our apartment communities, we compete with numerous other housing providers. Our apartment 
communities compete directly with other rental apartments as well as condominiums and single-family homes that are available for rent or purchase 
in the markets in which our apartment communities are located. Principal factors of competition include rent or price charged, attractiveness of the 
location and apartment community, and the quality and breadth of services. The number of competitive apartment communities relative to demand 
in a particular area has a material effect on our ability to lease apartment homes at our communities and on the rents we charge. In certain markets, 
there exists an oversupply of newly-constructed apartment homes, single-family homes, and condominiums relative to consumer demand, which 
affects the pricing and occupancy of our rental apartments.  

We also compete with other real estate investors, including other apartment REITs, pension and investment funds, partnerships, and investment 
companies in acquiring, redeveloping, managing, obtaining financing for, and disposing of apartment communities. This competition affects our 
ability to acquire apartment communities we want to add to our portfolio and the price that we pay  

5 

 
 
Table of Contents 

in such acquisitions; our ability to finance 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. 

Taxation  

Aimco 

Aimco has elected to be taxed as a REIT under the Internal Revenue Code of 1986, as amended, which we refer to as the Code, commencing with 
our taxable year ended December 31, 1994, and intends to continue to operate in such a manner. The Code imposes various requirements related to 
organizational structure, distribution levels, diversity of stock ownership, and certain restrictions with regard to owned assets and categories of 
income that must be met in order to continue to qualify as a REIT. If Aimco continues to qualify for taxation as a REIT, Aimco will generally not be 
subject to United States federal corporate income tax on its taxable income that is currently distributed to stockholders. This treatment substantially 
eliminates the “double taxation” (at the corporate and stockholder levels) that generally results from an investment in a corporation. 

Certain of Aimco’s 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 and activities to our residents and 
investment partners that cannot be offered directly by a REIT. We also use TRS entities to hold investments in certain apartment communities.  

The Aimco Operating Partnership 

The  Aimco  Operating  Partnership  is  treated  as  a  “pass-through” entity  for  United  States  federal  income  tax  purposes  and  is  not  subject  to 
United  States  federal  income  taxation.  Partners  in  the  Aimco  Operating  Partnership,  however,  are  subject  to  tax  on  their  allocable  share  of 
partnership  income,  gains,  losses,  deductions,  and  credits,  regardless  of  whether  the  partners  receive  any  actual  distributions  of  cash  or  other 
property from the Aimco Operating Partnership during the taxable year. Generally, the characterization of any particular item is determined by the 
Aimco Operating Partnership, rather than at the partner level, and the amount of a partner’s allocable share of such item is governed by the terms of 
the Aimco Operating Partnership’s Partnership Agreement. The Aimco Operating Partnership is subject to tax in certain states. 

Regulation 

General 

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 would 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,  such  as  legislation  that  has  been  considered  in  New  York  and  certain  cities  in 
California, or other laws regulating multifamily housing may reduce rental revenue or increase operating costs in particular markets. 

Environmental  

Various federal, state, and local laws subject apartment community owners or operators to liability for management, and the costs of removal or 
remediation,  of  certain  potentially  hazardous  materials  that  may  be  present  at  an  apartment  community.  These  materials  may  include  lead-based 
paint, asbestos, polychlorinated biphenyls, and petroleum-based fuels. Such laws often impose liability without regard to fault or whether the owner 
or  operator  knew  of,  or  was  responsible  for,  the  release  or  presence  of  such  materials.  In  connection  with  the  ownership,  operation,  and 
management of apartment communities, we could potentially be liable for environmental liabilities or costs associated with our current apartment 
communities, communities we acquire or manage in the future, or communities we previously owned or operated in the past. These and other risks 
related to environmental matters are described in more detail in Item 1A. Risk Factors. 

Insurance 

Our primary lines of insurance coverage are property, general liability, and workers’  compensation. We believe that our insurance coverages 
adequately insure our apartment communities against the risk of loss attributable to fire, earthquake, hurricane, tornado, flood, terrorism, and other 
perils, and adequately insure us against other risk. Our coverage includes deductibles, retentions and  

6 

 
 
Table of Contents 

limits  that  are  customary  in  the  industry.  We  have  established  loss  prevention,  loss  mitigation,  claims  handling,  and  litigation  management 
procedures to manage our exposure. 

Employees 

At December 31, 2017, we had approximately 1,350 team members, of which about 1,000 were at the apartment community level performing on-site 
functions,  or  at  our  shared  service  center  performing  tasks  that  have  been  centralized  there,  with  the  balance  managing  corporate  and  area 
functions,  including  investment  and  debt  transactions,  legal,  finance  and  accounting,  information  systems,  human  resources  and  other  support 
functions. As of December 31, 2017, unions represented approximately 80 of our team members. We have never experienced a work stoppage and 
believe we maintain satisfactory relations with our team members.  

Available Information 

Our combined Annual Report on Form 10-K, our combined Quarterly Reports on Form 10-Q, Current Reports on Form 8-K filed by Aimco or the 
Aimco Operating Partnership and any amendments to any of those reports that we file with the Securities and Exchange Commission are available 
free of charge as soon as reasonably practicable through Aimco’s website at www.aimco.com. The information contained on Aimco’s website is not 
incorporated into this Annual Report. Aimco’s Common Stock is listed on the New York Stock Exchange under the symbol “AIV.” In 2017, Aimco’s 
chief  executive  officer  submitted  his  annual  corporate  governance  listing  standards  certification  to  the  New  York  Stock  Exchange,  which 
certification was unqualified. 

Item 1A. Risk Factors 

The risk factors noted in this section and other factors noted throughout this Annual Report, describe certain risks and uncertainties that could 

cause our actual results to differ materially from those contained in any forward-looking statement. 

Redevelopment, development and construction risks could affect our profitability.  

We  are  currently  redeveloping  certain  of  our  apartment  communities.  During  2018,  we  expect  to  invest  $120  million  to  $200  million  in 

redevelopment and development activities. Redevelopment and development are subject to numerous risks, including the following:  

•  we may be unable to obtain, or experience delays in obtaining, necessary zoning, occupancy, or other required governmental or third-party 

permits and authorizations, which could result in increased costs or the delay or abandonment of opportunities;  

•  we may incur costs that exceed our original estimates due to increased material, labor or other costs, such as litigation; 

•  we may be unable to complete construction and lease-up of an apartment community on schedule, resulting in increased construction and 

financing costs and a decrease in expected rental revenues; 

• 

occupancy  rates  and  rents  at  an  apartment  community  may  fail  to  meet  our  expectations  for  a  number  of  reasons,  including  changes  in 
market and economic conditions beyond our control and the development of competing communities;  

•  we may be unable to obtain financing with favorable terms, or at all, which may cause us to delay or abandon an opportunity;

•  we  may  abandon  opportunities  that  we  have  already  begun  to  explore,  or  stop  projects  we  have  already  commenced,  for  a  number  of 
reasons, including changes in local market conditions or increases in construction or financing costs, and, as a result, we may fail to recover 
costs already incurred in exploring those opportunities; 

•  we may incur liabilities to third parties during the redevelopment or development process; 

• 

• 

unexpected events or circumstances may arise during the redevelopment or development process that affect the timing of completion and 
the cost and profitability of the redevelopment or development; and 

loss  of  a  key  member  of  a  redevelopment  or  development  team  could  adversely  affect  our  ability  to  deliver  redevelopments  and 
developments on time and within our budget. 

Failure to generate sufficient net operating income may adversely affect our liquidity, limit our ability to fund necessary capital expenditures 
or adversely affect our ability to pay dividends or distributions. 

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. 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. 

7 

 
 
Table of Contents 

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. Our net operating income and liquidity may be adversely affected by events or conditions beyond our control, 
including: 

• 

• 

• 

• 

• 

• 

• 

the general economic climate; 

an inflationary environment in which the costs to operate and maintain our communities increase at a rate greater than our ability to increase 
rents, which we can only do upon renewal of existing leases or at the inception of new leases; 

competition from other apartment communities and other housing options;

local conditions, such as loss of jobs, unemployment rates, or an increase in the supply of apartments, that might adversely affect apartment 
occupancy or rental rates; 

changes in governmental regulations and the related cost of compliance;

changes in tax laws and housing laws, including the enactment of rent control laws or other laws regulating multifamily housing; and

changes in interest rates and the availability of financing. 

Competition could limit our ability to lease apartment homes or increase or maintain rents.  

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.  

Because real estate investments are relatively illiquid, we may not be able to sell apartment communities when appropriate.  

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. 

If we are not successful in our acquisition of apartment communities, our results of operations could be adversely affected. 

The  selective  acquisition  of  apartment  communities  is  a  component  of  our  strategy.  However,  we  may  not  be  able  to  complete  transactions 
successfully in the future. Although we seek to acquire apartment communities when such acquisitions increase our free cash flow internal rate of 
returns and are accretive to Net Asset Value, such transactions may fail to perform in accordance with our expectations. In particular, following 
acquisition, the value and operational performance of an apartment community may be diminished if obsolescence or neighborhood changes occur 
before we are able to redevelop or sell the community. This could have an adverse effect on our financial condition or results of operations. 

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

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 existing indebtedness may not be refinanced or that the terms of any refinancing will not be as favorable as the terms of 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, 2017, the majority of our 
apartment communities were encumbered by debt. 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 be paid in order to maintain Aimco’s 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 revolving credit agreement, more difficult. In particular, apartment  

8 

 
 
Table of Contents 

borrowers  have  benefited  from  the  historic  willingness  of  Federal  National  Mortgage  Association,  or  Fannie  Mae,  and  the  Federal  Home  Loan 
Mortgage  Corporation,  or  Freddie  Mac,  to  make  substantial  amounts  of  loans  secured  by  multi-family  properties,  even  in  times  of  economic 
distress. These two lenders are federally chartered and subject to federal regulation, 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, 
each of which would adversely affect our liquidity. 

Increases in interest rates would increase our interest expense and reduce our profitability. 

As  of  December  31,  2017,  we  had  approximately  $399.8  million  of  variable-rate  indebtedness  outstanding  associated  with  our  Real  Estate 
portfolio. We estimate that an increase in 30-day LIBOR of 100 basis points with constant credit risk spreads would reduce our net income and the 
amount of net income attributable to our common security holders (including Aimco common stockholders and the Aimco Operating Partnership’s 
common unitholders) by approximately $3.8 million on an annual basis.  

At December 31, 2017, our Real Estate portfolio had approximately $95.3 million in cash and cash equivalents and restricted cash, a portion of 
which bear interest at variable rates indexed to LIBOR-based rates, which may partially mitigate the effect of an increase in variable rates on our 
variable-rate indebtedness discussed above. 

Covenant restrictions may limit our ability to make payments to our investors. 

Some of our debt and other securities contain covenants that restrict our ability to make distributions or other payments to our investors unless 
certain  financial  tests  or  other  criteria  are  satisfied.  Our  revolving  credit  agreement  provides,  among  other  things,  that  we  may  not  make 
distributions to our investors during any four consecutive fiscal quarters in an aggregate amount greater than 95% of our Funds From Operations 
for such period, subject to certain non-cash adjustments, or such amount as may be necessary to maintain Aimco’s REIT status. Our outstanding 
classes of preferred stock or preferred units prohibit the payment of dividends on our Common Stock or common partnership units if we fail to pay 
the dividends to which the holders of the preferred stock or preferred units are entitled.  

The Aimco Operating Partnership and its subsidiaries may be prohibited from making distributions and other payments. 

All of Aimco’s apartment communities are owned, and all of Aimco’s operations are conducted, by the Aimco Operating Partnership. Further, 
many of the Aimco Operating Partnership’s apartment communities are owned by subsidiaries of the Aimco Operating Partnership. As a result, 
Aimco  depends  on  distributions  and  other  payments  from  the  Aimco  Operating  Partnership,  and  the  Aimco  Operating  Partnership  depends  on 
distributions and payments from its subsidiaries in order to satisfy our financial obligations and make payments to our investors. The ability of the 
Aimco Operating Partnership and its subsidiaries to make such distributions and other payments depends on their earnings and cash flows and 
may be subject to statutory or contractual limitations. As an equity investor in the Aimco Operating Partnership and its subsidiaries, our right to 
receive assets upon their liquidation or reorganization will be effectively subordinated to the claims of their creditors. To the extent that we are 
recognized as a creditor of such subsidiaries, our claims may still be subordinate to any security interest in or other lien on their assets and to any 
of their debt or other obligations that are senior to our claims. 

Potential liability or other expenditures associated with potential environmental contamination may be costly. 

Various federal, state and local laws subject apartment community 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.  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 knew of, or was responsible for, the presence of such materials. The 
presence of, or the failure to manage or remediate properly, these materials may adversely affect occupancy at such apartment communities as well 
as  the  ability  to  sell  or  finance  such  apartment  communities.  In  addition,  governmental  agencies  may  bring  claims  for  costs  associated  with 
investigation and remediation actions, damages to natural resources and for potential fines or penalties in connection with such damage or with 
respect  to  the  improper  management  of  hazardous  materials.  Moreover,  private  plaintiffs  may  potentially  make  claims  for  investigation  and 
remediation costs they incur or personal injury, disease, disability or other infirmities related to the alleged presence of hazardous materials at an 
apartment community. In addition to potential environmental liabilities or costs associated with our current apartment communities, we may also be 
responsible for such liabilities or costs associated with communities we acquire or manage in the future, or apartment communities we no longer 
own or operate.

Laws benefiting disabled persons may result in our incurrence of unanticipated expenses. 

Under the Americans with Disabilities Act of 1990, or 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, 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. 

Moisture infiltration and resulting mold remediation may be costly.  

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. 

Government  housing  regulations  may  limit  the  opportunities  at  some  of  our  apartment  communities  and  failure  to  comply  with  resident 
qualification  requirements  may  result  in  financial  penalties  and/or  loss  of  benefits,  such  as  rental  revenues  paid  by  government  agencies. 
Additionally, the government may cease to operate or reduce funding for government housing programs which would result in a loss of benefits 
from those programs. 

We own equity interests in consolidated and unconsolidated entities that own certain apartment communities that benefit from governmental 
programs intended to provide housing to people with low or moderate incomes. These programs, which are usually administered by the United 
States Department of Housing and Urban Development, or HUD, or state housing finance agencies, typically provide one or more of the following: 
mortgage insurance; favorable financing terms; tax-exempt interest; historic or low-income housing tax credits; or rental assistance payments to the 
apartment  community  owners.  As  a  condition  of  the  receipt  of  assistance  under  these  programs,  the  apartment  communities  must  comply  with 
various requirements, which typically limit rents to pre-approved amounts and limit our choice of residents to those with incomes at or below certain 
levels. Failure to comply with these requirements may result in financial penalties or loss of benefits. We are usually required to obtain the approval 
of HUD in order to acquire or dispose of a significant interest in or manage a HUD-assisted apartment community. We may not always receive such 
approval.  

Additionally,  there  is  no  guarantee  that  the  government  will  continue  to  operate  these  programs  or  that  the  programs  will  be  operated  in  a 
manner that generates benefits consistent with those received in the past. Any cessation of or change in the administration of benefits from these 
government housing programs may result in our loss or reduction in the amount of the benefits we receive under these programs, including rental 
subsidies.  During  2017,  2016  and  2015,  rental  revenues  for  our  Real  Estate  portfolio  included  $30.6  million,  $30.9  million  and  $25.6  million, 
respectively, from subsidies from government agencies. Of the 2017 subsidies, approximately 23.9% related to communities sold during 2017 leaving 
about $7.1 million related to communities benefiting from housing assistance contracts that expire in 2018, which we are in the process of renewing 
or  anticipate  renewing,  and  $16.2  million  related  to  communities  benefiting  from  housing  assistance  contracts  that  expire  after  2018  and  had  a 
weighted  average  term  of  8.0  years.  Any  loss  or  reduction  in  the  amount  of  these  benefits  may  adversely  affect  our  liquidity  and  results  of 
operations.  

We also hold nominal ownership positions in partnerships owning low-income housing tax credit communities. We provide services to these 
partnerships and receive fees and other payments in return. We refer to this relationship as our Asset Management business. During 2017, 2016 and 
2015, rental revenues of communities owned by partnerships served by our Asset Management business included $49.0 million, $49.3 million and 
$47.8 million, respectively, of subsidies from government agencies. 

Although we are insured for certain risks, the cost of insurance, increased claims activity or losses resulting from casualty events may affect our 
operating results and financial condition. 

We are insured for a portion of our consolidated apartment communities’ 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 community and the amount of any related  

10 

 
 
Table of Contents 

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 and severe weather may affect our operating results and financial condition. 

Natural disasters such as earthquakes and severe weather such as hurricanes may result in significant damage to our apartment communities. 
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 results will not be adversely affected by our exposure to losses arising from natural disasters or severe weather in the 
future that exceed our previous experience and assumptions.  

We depend on our senior management.  

Our  success  depends  upon  the  retention  of  our  senior  management,  including  Terry  Considine,  our  chief  executive  officer.  We  have  a 
succession planning and talent development process that is designed to identify potential replacements and develop our team members to provide 
depth  in  the  organization  and  a  bench  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. The loss of services of one or more 
members of our senior management team could have a material adverse effect on our business, financial condition and results of operations. We do 
not currently maintain key-man life insurance for any of our employees.  

Aimco may fail to qualify as a REIT. 

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 
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 would 
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 as a REIT for United States federal income tax purposes. 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  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 States 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, 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 Board of Directors 
may determine to revoke its REIT status.  

REIT distribution requirements limit our available cash. 

As a REIT, Aimco is subject to annual distribution requirements. The Aimco Operating Partnership pays distributions 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 taxable income, determined without regard to the dividends paid deduction and 
excluding any net capital gain, in order for its distributed earnings not to be  

11 

 
 
Table of Contents 

subject to United States federal corporate income tax. We intend to make distributions to Aimco’s stockholders to comply with the requirements of 
the Code. 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. 

Aimco may be subject to federal and state income taxes, in certain circumstances. 

Even if Aimco qualifies as a REIT, Aimco may be subject to United States federal income and excise taxes in various situations, such as on its 
undistributed income. Aimco could also be required to pay a 100% tax on any net income on non-arm’s length transactions between Aimco and a 
taxable REIT subsidiary and on any net income from sales of apartment communities that were held for sale primarily in the ordinary course. State 
and local tax laws may not conform to the United States federal income tax treatment, and Aimco may be subject to state or local taxation in various 
state or local jurisdictions in which Aimco transacts business. Any taxes imposed on Aimco would reduce our operating cash flow and net income 
and could negatively impact our ability to pay dividends and distributions. 

Dividends payable by REITs do not qualify for the reduced tax rates available for some dividends. 

REITs are entitled to a U.S. federal tax deduction for dividends paid to their stockholders. As compared to other taxable corporations, this ability 
to reduce or eliminate the REIT’s taxable income by paying dividends to stockholders is a principal benefit of maintaining REIT status, generally 
resulting  in  a  lower  combined  tax  liability  of  the  REIT  and  its  stockholders  as  compared  to  that  of  the  combined  tax  liability  of  other  taxable 
corporations and their stockholders. Notwithstanding this combined benefit, dividends payable by REITs may result in marginally higher taxes to 
the stockholder.  

C-corporations are generally required to pay U.S. federal income tax on earnings. After tax earnings are then available for stockholder dividends. 
The  maximum  U.S.  federal  tax  rate  applicable  to  income  from  "qualified  dividends"  payable  to  U.S.  stockholders  that  are  individuals,  trusts  and 
estates  is  currently  20%,  plus  the  3.8%  investment  tax  surcharge.  While  dividends  payable  by  REITs  are  generally  not  eligible  for  the  qualified 
dividend reduced rates, stockholders that are individuals, trusts or estates may deduct 20% of the aggregate amount of ordinary dividends from 
REITs.  This  deduction  is  available  for  taxable  years  beginning  after  December  31,  2017  and  before  January  1,  2026  and  will  generally  cause  the 
maximum tax rate for ordinary dividends from REITs to be 29.6%, plus the 3.8% investment tax surcharge. 

Beginning in 2018, REIT dividends payable to individuals, trusts and estates can be taxed at 20% for capital gains and qualified dividends, 25% 
for unrecaptured Section 1250 gains, or 29.6% for ordinary dividends, whereas qualified dividends from C-corporations are generally taxed at 20%. 
Both are subject to the 3.8% investment tax surcharge. Based on the character of Aimco’s 2017 REIT dividends, the effective U.S. federal income tax 
rate that would be be paid on Aimco’s 2018 dividends by stockholders who are individuals, trusts and estates would be 25.5% before considering 
the 3.8% investment tax surcharge. To the extent, the character of Aimco’s 2018 REIT dividends are similar to that of 2017, Aimco dividends would 
be taxed at a marginal rate 5.5% higher than the rate for a C-corporation dividend. In 2017, the ordinary income portion of of Aimco’s REIT taxable 
income was elevated compared to prior years. If the character of Aimco’s 2018 REIT dividends are similar to the average of the last three years, 
Aimco dividends would be taxed at a marginal rate 4.6% higher than the rate for a C-corporation dividend.  

Changes to U.S. federal income tax laws could materially and adversely affect Aimco and Aimco's stockholders. 

The present U.S. federal income tax treatment of REITs may be modified, possibly with retroactive effect, by legislative, judicial or administrative 
action at any time, which could affect the U.S. federal income tax treatment of an investment in Aimco Common Stock. The U.S. federal income tax 
rules dealing with REITs constantly are under review by persons involved in the legislative process, the IRS and the U.S. Treasury Department, 
which results in statutory changes as well as frequent revisions to regulations and interpretations. The recently enacted Tax Cuts and Jobs Act 
made substantial changes to the Code. Among those changes are a significant permanent reduction in the generally applicable corporate tax rate, 
changes in the taxation of individuals and other non-corporate taxpayers that generally but not universally reduce their tax rates on a temporary 
basis subject to ‘‘sunset” provisions, the elimination or modification of various currently allowed deductions (including substantial limitations on 
the deductibility of interest and, in the case of individuals, the deduction for personal state and local taxes), certain additional limitations on the 
deduction  of  net  operating  losses,  and  preferential  rates  of  taxation  on  most  ordinary  REIT  dividends  and  certain  business  income  derived  by 
noncorporate taxpayers in comparison to other ordinary income recognized by such taxpayers. The effect of these and the many other changes 
made in the Tax Cuts and Jobs Act is highly uncertain, both in terms of their direct effect on the taxation of an investment in our common stock and 
their indirect effect on market conditions generally. Furthermore, many of the provisions of the Tax Cuts and Jobs Act will require guidance through 
the issuance of Treasury regulations in order to assess their effect. There may be a substantial delay before such regulations are promulgated, 
increasing  the  uncertainty  as  to  the  ultimate  effect  of  the  statutory  amendments  on  Aimco.  There  may  also  be  technical  corrections  legislation 
proposed with respect to the Tax Cuts and Jobs Act, the effect and timing of which cannot be predicted and may be adverse to Aimco or Aimco's 
stockholders.

Investors are urged to consult their tax advisors with respect to these changes and the potential effect on their investment in Aimco’s Common 
Stock. 

Limits on ownership of shares specified in Aimco’s charter may result in the loss of economic and voting rights by purchasers that violate those 
limits. 

Aimco’s charter limits ownership of Common Stock by any single stockholder (applying certain “beneficial ownership” rules under the federal 
securities laws) to 8.7% (or up to 12.0% upon a waiver from Aimco’s Board of Directors) of outstanding shares of Common Stock, or 15% in the 
case of certain pension trusts, registered investment companies and Mr. Considine (or up to 18.0% for such pension trusts or registered investment 
companies upon a waiver from Aimco’s Board of Directors). Aimco’s charter also limits ownership of Aimco’s Common Stock and preferred stock 
by any single stockholder to 8.7% of the value of the outstanding Common Stock and preferred stock, or 15% in the case of certain pension trusts, 
registered investment companies and Mr. Considine. The charter also prohibits anyone from buying shares of Aimco’s capital stock if the purchase 
would result in Aimco losing its REIT status. This could happen if a transaction results in fewer than 100 persons owning all of Aimco’s shares of 
capital stock or results in five or fewer persons (applying certain attribution rules of the Code) owning 50% or more of the value of all of Aimco’s 
shares of capital stock. If anyone acquires shares in excess of the ownership limit or in violation of the ownership requirements of the Code for 
REITs: 

• 

the transfer will be considered null and void; 

•  we will not reflect the transaction on Aimco’s books; 

•  we may institute legal action to enjoin the transaction; 

•  we may demand repayment of any dividends received by the affected person on those shares;

•  we may redeem the shares; 

• 

• 

the affected person will not have any voting rights for those shares; and

the shares (and all voting and dividend rights of the shares) will be held in trust for the benefit of one or more charitable organizations 
designated by Aimco. 

Aimco may purchase 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: 

•  may lose control over the power to dispose of such shares; 

•  may not recognize profit from the sale of such shares if the market price of the shares increases;

•  may be required to recognize a loss from the sale of such shares if the market price decreases; and

•  may be required to repay to us any dividends received from us as a result of his or her ownership of the shares.

Aimco’s charter may limit the ability of a third-party to acquire control of Aimco. 

The 8.7% and other ownership limits discussed above may have the effect of delaying or precluding acquisition by a third-party of control of 
Aimco without the consent of Aimco’s Board of Directors. Aimco’s charter authorizes its Board of Directors to issue up to 510,587,500 shares of 
capital stock. As of December 31, 2017, 500,787,260 shares were classified as Common Stock, of which 157,189,447 were outstanding, and 9,800,240 
shares were classified as preferred stock, of which 5,000,000 were outstanding. Under Aimco’s charter, its Board of Directors has the authority to 
classify  and  reclassify  any  of  Aimco’s unissued shares of capital stock into shares of capital stock with such preferences, conversion or other 
rights, voting power restrictions, limitations as to dividends, qualifications or terms or conditions of redemptions as the Board of Directors may 
determine. The authorization and issuance of a new class of capital stock could have the effect of delaying or preventing someone from taking 
control of Aimco, where there is a difference of opinion between the Aimco Board of Directors and others as to what is in Aimco’s stockholders’ 
best interests. 

The Maryland General Corporation Law may limit the ability of a third-party to acquire control of Aimco. 

As a Maryland corporation, Aimco is subject to various Maryland laws that may have the effect of discouraging offers to acquire Aimco and 
increasing the difficulty of consummating any such offers, where there is a difference of opinion between the Aimco Board of Directors and others 
as to what is in Aimco’s stockholders’ best interests. The Maryland General Corporation Law, specifically the Maryland Business Combination Act, 
restricts mergers and other business combination transactions between Aimco  

13 

 
 
Table of Contents 

and any person who acquires, directly or indirectly, beneficial ownership of shares of Aimco’s stock representing 10% or more of the voting power 
without Aimco’s Board of Directors’ prior approval. Any such business combination transaction could not be completed until five years after the 
person acquired such voting power, and generally only with the approval of stockholders representing 80% of all votes entitled to be cast and 66-
2/3% of the votes entitled to be cast, excluding the interested stockholder, or upon payment of a fair price. The Maryland General Corporation Law, 
specifically  the  Maryland  Control  Share  Acquisition  Act,  provides  generally  that  a  person  who  acquires  shares  of  Aimco’s  capital  stock 
representing 10% or more of the voting power in electing directors will have no voting rights unless approved by a vote of two-thirds of the shares 
eligible to vote. Additionally, the Maryland General Corporation Law provides, among other things, that the board of directors has broad discretion 
in adopting stockholders’ rights plans and has the sole power to fix the record date, time and place for special meetings of the stockholders. To 
date, Aimco has not adopted a stockholders’ rights plan. In addition, the Maryland General Corporation Law provides that a corporation that: 

• 

• 

has at least three directors who are not officers or employees of the entity or related to an acquiring person; and

has a class of equity securities registered under the Securities Exchange Act of 1934, as amended,

may elect in its charter or bylaws or by resolution of the board of directors to be subject to all or part of a special subtitle that provides that: 

• 

• 

• 

• 

• 

the corporation will have a staggered board of directors; 

any  director  may  be  removed  only  for  cause  and  by  the  vote  of  two-thirds  of  the  votes  entitled  to  be  cast  in  the  election  of  directors 
generally, even if a lesser proportion is provided in the charter or bylaws; 

the number of directors may only be set by the board of directors, even if the procedure is contrary to the charter or bylaws;

vacancies may only be filled by the remaining directors, even if the procedure is contrary to the charter or bylaws; and

the secretary of the corporation may call a special meeting of stockholders at the request of stockholders only on the written request of the 
stockholders entitled to cast at least a majority of all the votes entitled to be cast at the meeting, even if the procedure is contrary to the 
charter or bylaws. 

To date, Aimco has not made any of the elections described above.

Additional  information  about  our  consolidated  apartment  communities  is  contained  in  “Schedule  III  -  Real  Estate  and  Accumulated 
Depreciation” in this Annual Report on Form 10-K. Refer to  Note 4 to the consolidated financial statements in Item 8 for additional information 
regarding property debt.  

Our Real Estate portfolio is diversified by both price point and geography and consists of market rate apartment communities in which we own a 
substantial  interest.  Our  Real  Estate  portfolio  includes  garden  style,  mid-rise and high-rise  apartment  communities  located  in  22  states  and  the 
District of Columbia. Our portfolio strategy seeks predictable rent growth from a portfolio of apartment communities diversified among some of the 
largest markets in the United States, and that is diversified across “A,” “B” and “C+” price points, averaging “B/B+” in quality. As of December 31, 
2017, our Real Estate portfolio consisted of roughly one half “A” quality communities and one half “B” and “C+” quality communities (as measured 
by gross asset value). Please refer to the Executive Overview heading under Item 7 for a description of our portfolio quality ratings. The following 
table sets forth information on the apartment communities in our Real Estate portfolio as of December 31, 2017:

At December 31, 2017, we owned an equity interest in 136 apartment communities with 36,904 apartment homes in our Real Estate portfolio. We 

consolidated 132 of these apartment communities with 36,762 apartment homes.  

These consolidated apartment communities contained, on average, 279 apartment homes, with the largest community containing 2,113 apartment 
homes.  These  apartment  communities  offer  residents  a  range  of  amenities,  including  resort  pools  with  cabanas,  grills,  clubhouses,  spas,  fitness 
centers,  package  lockers,  dog  parks  and  large  open  spaces.  Many  of  the  apartment  homes  offer  features  such  as  granite  countertops,  wood 
flooring, stainless steel appliances, fireplaces, spacious closets, washer and dryer connections, balconies and patios.  

The majority of our consolidated apartment communities are encumbered by property debt. At December 31, 2017, apartment communities in our 
Real Estate portfolio were encumbered by, in aggregate, $3.5 billion of property debt with a weighted average interest rate of 4.6% and a weighted 
average maturity of 7.2 years. The apartment communities collateralizing this non-recourse property debt have an estimated aggregate fair value of 
$10.9 billion. At December 31, 2017, we held unencumbered apartment communities with an estimated fair value of approximately $1.8 billion. 

At December 31, 2017, we also held nominal ownership positions in partnerships that own 46 apartment communities with 6,898 apartment homes 
that qualify for low-income housing tax credits and are structured to provide for the pass through of tax credits and tax deductions to their partners. 
We  provide  asset  management  and  other  services  to  these  partnerships  and  receive  fees  and  other  payments  in  return.  In  accordance  with 
accounting  principles  generally  accepted  in  the  United  States  of  America,  or  GAAP,  we  consolidate  most  of  these  partnerships,  which  own  an 
aggregate of 39 apartment communities with 6,211 apartment homes. 

Item 3. Legal Proceedings 

As  further  discussed  in  Note  5  to  the  consolidated  financial  statements  in  Item  8,  we  are  engaged  in  discussions  with  regulatory  agencies 
regarding environmental matters at apartment communities we, or predecessor entities, previously owned. Although the outcome of these matters is 
uncertain, we do not expect the resolution to have a material adverse effect on our consolidated financial condition, results of operations or cash 
flows.

Aimco’s Board of Directors determines and declares its dividends. In making a dividend determination, Aimco’s Board of Directors considers a 
variety  of  factors,  including:  REIT  distribution  requirements;  current  market  conditions;  liquidity  needs;  and  other  uses  of  cash,  such  as  for 
deleveraging and accretive investment activities. Aimco’s Board of Directors targets a dividend payout ratio between 65% and 70% of Adjusted 
Funds From Operations (which is defined in Item 7). In January 2018, Aimco’s Board of Directors declared a cash dividend of $0.38 per share on its 
Common Stock. On an annualized basis, this represents an  increase of 6% compared to the dividends paid in  2017. This dividend is payable on 
February 28, 2018, to stockholders of record on February 16, 2018. Aimco’s Board of Directors anticipates similar per share quarterly cash dividends 
for the remainder of 2018. However, the Board of Directors may adjust the dividend amount or the frequency with which the dividend is paid based 
on then prevailing circumstances.  

On February 27,  2018, the closing price of Aimco Common Stock was  $38.43 per share, as reported on the NYSE, and there were 157,330,262 
shares of Common Stock outstanding, held by 1,741 stockholders of record. The number of holders does not include individuals or entities who 
beneficially own shares but whose shares are held of record by a broker or clearing agency, but does include each such broker or clearing agency 
as one record holder. 

As a REIT, Aimco is required to distribute annually to holders of its Common Stock at least 90% of its “real estate investment trust taxable 
income,”  which,  as  defined  by  the  Code  and  United  States  Department  of  Treasury  regulations,  is  generally  equivalent  to  net  taxable  ordinary 
income. 

From time to time, Aimco may issue shares of Common Stock in exchange for OP Units, defined under The Aimco Operating Partnership heading 
below. Please refer to Note  7 to the consolidated financial statements in Item 8 for further discussion of such exchanges. Aimco may also issue 
shares of Common Stock in exchange for limited partnership interests in consolidated real estate partnerships. During the year ended December 31, 
2017,  Aimco  did  not  issue  any  shares  of  Common  Stock  in  exchange  for  OP  Units  or  limited  partnership  interests  in  consolidated  real  estate 
partnerships.  

Aimco’s  Board  of  Directors  has,  from  time  to  time,  authorized  Aimco  to  repurchase  shares  of  its  outstanding  capital  stock.  There  were  no 
repurchases  of  Aimco  shares  during  the  year  ended  December  31,  2017.  As  of  December  31,  2017,  Aimco  was  authorized  to  repurchase 
approximately 19.3 million shares. This authorization has no expiration date. These repurchases may be made from time to time in the open market or 
in privately negotiated transactions.

Performance Graph 

The following graph compares cumulative total returns for Aimco’s Common Stock, the MSCI US REIT Index, the NAREIT Apartment Index, and 
the Standard & Poor’s 500 Total Return Index (the “S&P 500”). The MSCI US REIT Index is published by Morgan Stanley Capital International Inc., 
a provider of equity indices. The NAREIT Apartment Index is published by The National Association of Real Estate Investment Trusts, or NAREIT, 
a representative of real estate investment trusts and publicly traded real estate companies with interests in United States real estate and capital 
markets. The MSCI REIT Index reflects total shareholder return for a broad range of REITs and the NAREIT Apartment Index provides a more direct 
multifamily peer comparison of total shareholder return. The indices are weighted for all companies that fit the definitional criteria of the particular 
index and are calculated to exclude companies as they are acquired and to add companies to the index calculation as they become publicly traded 
companies. All companies that fit the definitional criteria and existed at the point in time presented are included in the index calculations. The graph 
assumes  the  investment  of  $100  in  Aimco’s  Common  Stock  and  in  each  index  on  December  31,  2012,  and  that  all  dividends  paid  have  been 
reinvested. The historical information set forth below is not necessarily indicative of future performance.

The Aimco Operating Partnership 

Interests in the Aimco Operating Partnership that are held by limited partners other than Aimco are referred to as OP Units. OP Units include 
common partnership units, which we refer to as common OP Units, as well as partnership preferred units, or preferred OP Units. There is no public 
market  for  the  Aimco  Operating  Partnership’s  common  partnership  units,  including  OP  Units,  and  we  have  no  intention  of  listing  the  common 
partnership units on any securities exchange. In addition, the Aimco Operating Partnership’s Partnership Agreement restricts the transferability of 
common  partnership  units,  including  OP  Units.  The  following  table  sets  forth  the  distributions  declared  per  common  partnership  unit  in  each 
quarterly period during the two years ended December 31, 2017 and 2016:

The Aimco Operating Partnership’s Board of Directors determines and declares its distributions. Aimco, through wholly-owned subsidiaries, is 
the general and special limited partner of and, as of December 31, 2017, owned a 95.5% ownership interest in the common partnership units of the 
Aimco  Operating  Partnership  and  the  Aimco  Operating  Partnership  holds  all  of  Aimco’s  assets  and  manages  the  daily  operations  of  Aimco’s 
business. The distributions paid by the Aimco Operating Partnership to Aimco are used by Aimco to fund the dividends paid to its stockholders.  
Accordingly,  the  per  share  dividends  Aimco  pays  to  its  stockholders  generally  equal  the  per  share  distributions  paid  by  the  Aimco  Operating 
Partnership to holders of its common partnership units. 

At February 27, 2018, there were 164,901,915 common partnership units and equivalents outstanding (157,330,262 of which were held by Aimco) 

that were held by 2,624 unitholders of record. 

The Aimco Operating Partnership’s Partnership Agreement generally provides that after holding common OP Units for one year, limited partners 

other than Aimco have the right to redeem their common OP Units for cash or, at our election, shares of Aimco Common Stock. 

No common OP Units or preferred OP Units held by Limited Partners were redeemed for shares of Aimco Common Stock during the year ended 

December 31, 2017.

(1)  Effective January 1, 2014, we adopted a new accounting standard, which revised the definition of a discontinued operation. In the selected financial data 
presentation above, for the year ended December 31, 2013, total revenues excludes revenue generated by discontinued operations of $62.2 million and net 
income includes income from discontinued operations, net of tax, of $203.2 million.  

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations 

Executive Overview 

We are focused on the ownership, management, redevelopment and limited development of quality apartment communities located in some of 

the largest markets in the United States.  

Our  principal  financial  objective  is  to  provide  predictable  and  attractive  returns  to  our  equity  holders.  We  measure  our  current  return  using 
Adjusted Funds From Operations, or AFFO, and our long-term total return using Economic Income. In 2017, AFFO grew by 7.6% to $2.12 per share. 
Over the last five years, our Economic Income grew at a compound annual return of 13.7%, comprised of 10.6% compounded annual growth in net 
asset value, or NAV, per share and $5.78 in cash dividends per share paid over the period. We also use Pro forma Funds From Operations, or Pro 
forma FFO, as a measure of operational performance. Economic Income, NAV, AFFO, and Pro forma FFO are non-GAAP measures and are defined 
under the Non-GAAP Measures heading below. 

Our business and five areas of strategic focus are described in more detail within the Business Overview in Item 1. The results from execution of 

our business plan in 2017 are further described in the sections that follow.  

Net income attributable to common stockholders per common share decreased by $0.71 for the year ended December 31, 2017, as compared to 
2016, primarily due to lower gains on the sale of apartment communities and higher depreciation expense, partially offset by increased contribution 
from property net operating income more fully described below.  

Pro forma FFO per share increased $0.13, or 5.6%, for the year ended December 31, 2017, as compared to 2016. The primary driver of this increase 

was property net operating income growth of $0.11 per share, consisting of:  

• 

• 

$0.10  from  Same  Store  property  net  operating  income  growth  of  4.2%,  driven  primarily  by  a  3.2%  increase  in  revenue  and  almost  flat 
expense growth;  

$0.12 from the lease-up over the last 12 months of more than 800 renovated homes at redevelopment communities and completion of the 
lease-up of One Canal in Boston, and Indigo in Redwood City, California; and

Table of Contents 

• 

• 

$0.02 from our Other Real Estate apartment communities, primarily due to rate increases; partially offset by 

$0.13 lower property net operating income from apartment communities sold in 2016 to fund redevelopment and development activities and 
acquisitions.  

As compared to 2016, lower interest rates, higher tax benefit, higher transactional income and other factors, partially offset by lower deferred tax 

credit income, contributed an additional $0.02 to Pro forma FFO per share. 

The $0.13 increase in year-over-year Pro forma FFO per share plus $0.02 in lower capital replacement spending due to fewer apartment homes 

increased AFFO by $0.15, or 7.6% per share.  

Operational Excellence 

We own and operate a portfolio of market rate apartment communities diversified by both geography and price point. At December 31, 2017, our 
Real Estate portfolio included 136 apartment communities with 36,904 apartment homes in which we held an average ownership of approximately 
99%.  

Our property operations team delivered solid results for our Real Estate portfolio for the year ended December 31, 2017. Highlights include:  

• 

• 

Same Store net operating income growth greater than 4% for the seventh year in a row; 

Same Store rent increases on renewals and new leases averaged 4.6% and 0.6%, respectively, for a weighted average increase of 2.5%; and

•  Completion of the lease-up of One Canal in Boston, and Indigo in Redwood City, California. 

Our focus on efficient operations through productivity initiatives such as centralization of administrative tasks, optimization of economies of 
scale at the corporate level, and investment in more durable, longer-lived materials has helped us control operating expenses. As a result of these 
efforts, our Same Store controllable operating expenses, which we define as property operating expenses before real estate taxes, insurance and 
utilities,  decreased  by  1.3%  for  the  year  ended  December  31,  2017  compared  to  2016.  The  compounded  annual  growth  rate  for  Same  Store 
controllable operating expenses for the past decade is negative 0.4%. 

For the year ended December 31, 2017, our Real Estate portfolio provided 69% net operating income margins and 64% Free Cash Flow margins. 

Free Cash Flow is defined under the Non-GAAP Measures heading below.  

In addition to those communities in our Real Estate portfolio, as of December 31, 2017, we held nominal ownership positions (generally less than 
1%) in partnerships that own 46 low-income housing tax credit communities with 6,898 apartment homes. We provide asset management and other 
services to these partnerships and receive fees and other payments in return. Our relationship with these partnerships is different than real estate 
ownership and is better described as an Asset Management business. We have limited upside or downside exposure. In accordance with GAAP, 
we consolidate most of these partnerships and communities, thus reflecting their operating results as though they were our own until our fee and 
other interests have been repaid, generally upon sale of the underlying communities. 

Redevelopment 

Our second line of business is the redevelopment and development of apartment communities where we create value equal to 25% to 35% of our 
incremental investment by repositioning communities within the Aimco portfolio and by constructing new communities. We measure the rate and 
quality of financial returns by Net Asset Value creation, an important component of Economic Income, our primary measure of long-term financial 
performance. We invest to earn risk-adjusted returns in excess of those expected from the apartment communities sold in paired trades to fund the 
redevelopment or development.  

We  also  undertake  ground-up  development  when  warranted  by  risk-adjusted  investment  returns,  either  directly  in  connection  with  the 
redevelopment of an existing apartment community or, on a more limited basis, at a new location. When warranted, we rely on the expertise and 
credit of a third-party developer familiar with the local market to limit our exposure to construction risk. 

Of  these  two  activities,  we  favor  redevelopment  because  it  permits  adjustment  of  the  scope  and  timing  of  spending  to  align  with  changing 

market conditions and customer preferences. 

During the year ended December 31, 2017, we invested $172.4 million primarily in our ongoing redevelopment and development projects.

Table of Contents 

During the year ended December 31, 2017, we completed construction on the third tower of Park Towne Place in Center City, Philadelphia. As of 
December 31, 2017, the first three towers combined were 89% leased with approximately 40 homes remaining to be leased at the third redeveloped 
tower to reach occupancy stabilization. Based on these results, we decided to proceed with a $40 million redevelopment of the fourth and final 
tower. We have completed de-leasing and commenced construction on this tower, and lease-up is scheduled to commence in the spring of 2018. 

We have planned and entitled a new $117.0 million, 226 apartment home community to be known as Parc Mosaic, located in Boulder, Colorado 
on the site of our Eastpointe community. As part of this plan, as of December 31, 2017, we completed the de-leasing of Eastpointe and commenced 
demolition and construction. The site is two miles from the new Google campus and is across the street from Ball Aerospace’s Technology Campus 
and Foothills Hospital. Building in Boulder is highly regulated and new supply is limited, notwithstanding higher enrollment at the University of 
Colorado and increased employment generally.  

Inclusive of these two new projects, our total estimated net investment in redevelopment and development activities is $714.6 million, with a 
projected weighted average net operating income yield on these investments of 6.1%, assuming untrended rents. As of December 31, 2017, $513.1 
million of this total has been funded. 

During 2017, we leased over 800 apartment homes at our redevelopment communities. As of December 31, 2017, our lease-up exposure at active 
redevelopment and development projects included approximately 611 apartment homes, of which 232 were in the fourth tower of Park Towne Place, 
which we expect to be available for lease beginning in the summer of 2018 and 215 were in Parc Mosaic, which we expect to be available for lease 
beginning in the summer of 2019.  

See  below  under  the  Liquidity  and  Capital  Resources  –  Redevelopment/Development  heading  for  additional  information  regarding  our 

redevelopment and development investment during the year ended December 31, 2017. 

Portfolio Management 

Our portfolio of apartment communities is diversified across  “A,” “B,”  and “C+” price points, averaging  “B/B+” in quality and is diversified 
across some of the largest markets in the U.S. We measure the quality of apartment communities in our Real Estate portfolio based on average rents 
of our apartment homes compared to local market average rents as reported by a third-party provider of commercial real estate performance and 
analysis. Under this rating system, we classify as “A”  quality apartment communities those earning rents greater than 125% of the local market 
average, as “B” quality apartment communities those earning rents between 90% and 125% of the local market average; as “C+” quality apartment 
communities  those  earning  rents  greater  than  $1,100  per  month,  but  lower  than  90%  of  local  market  average;  and  as  “C”  quality  apartment 
communities those earning rents less than $1,100 per month and lower than 90% of local market average. We classify as “B/B+” quality a portfolio 
that on average earns rents between 100% and 125% of the local market average rents where the portfolio is located. Although some companies and 
analysts within the multifamily real estate industry use apartment community quality ratings of “A,” “B,” and “C,” some of which are tied to local 
market rent averages, the metrics used to classify apartment community quality as well as the period for which local market rents are calculated may 
vary from company to company. Accordingly, our rating system for measuring apartment community quality is neither broadly nor consistently 
used in the multifamily real estate industry. 

As part of our portfolio strategy, we seek to sell up to 10% of our portfolio annually and to reinvest the proceeds from such sales in accretive 
uses such as capital enhancements, redevelopments, occasional developments, and selective acquisitions with projected Free Cash Flow internal 
rates of return higher than expected from the communities being sold. Through this disciplined approach to capital recycling, we have significantly 
increased  the  quality  and  expected  growth  rate  of  our  portfolio,  resulting  in  a  compound  annual  growth  rate  in  average  revenue  per  Aimco 
apartment home of 8.8% over the last three years.

Table of Contents 

The quality of our portfolio improved through value created by our redevelopment and transaction activities, contributing to the increase in 
average revenue per apartment home. The increase is due to rent growth from the improved quality of our portfolio, driven in part by the sale of 
apartment  communities  with  average  monthly  revenues  per  Aimco  apartment  home  lower  than  those  of  the  retained  portfolio,  and  also  by  our 
reinvestment of the sales proceeds through redevelopment, development and acquisition of apartment communities with higher rents and better free 
cash flow return prospects than the apartment communities sold. 

As we execute our portfolio strategy, we expect to increase average revenue per Aimco apartment home for our Real Estate portfolio at a rate 
greater than market rent growth; increase free cash flow margins; and maintain sufficient geographic and price point diversification to moderate 
volatility and concentration risk. 

During the year ended December 31, 2017, we sold five apartment communities with 2,291 apartment homes for a gain of $297.9 million and gross 
proceeds of $397.0 million resulting in net proceeds of $381.1 million. Two of these apartment communities were affordable communities located in 
Washington, DC and Philadelphia, and three were located in southern New Jersey and southern Virginia. 

In January 2018, we agreed to sell our interests in the entities owning the La Jolla Cove property in settlement of legal actions filed in 2014 by a 
group of disappointed buyers who had hoped to acquire the property. As a result of the settlement, we recognized a gross impairment loss of $35.8 
million in our 2017 results, $25.6 million of which relates to the establishment of a deferred tax liability assumed in connection with our acquisition of 
the business entities. Upon closing of the transaction, the tax liability will be assumed by the buyer, resulting in no economic loss. The remaining 
$10.2 million loss is offset by cash distributions we received during our ownership and avoided legal costs for continued litigation. On an economic 
basis, we agreed to sell these entities at roughly our purchase price, adjusted for retained cash distributions and avoided legal costs. 

Also in January 2018, we sold three additional apartment communities with 513 apartment homes for a gain of approximately $50.0 million, net of 
tax, and gross proceeds of $71.9 million, resulting in $64.6 million in net proceeds. Two of these communities are located in southern Virginia and 
one is located in suburban Maryland. 

Proceeds from the 2017 and 2018 sales were used to repay outstanding borrowings on our revolving credit facility, effectively funding the equity 
portion  of  the  Palazzo  reacquisition,  as  further  discussed  in  Note  3  to  the  consolidated  financial  statements  in  Item  8,  as  well  as  our  2017 
redevelopment and development activities.  

Balance Sheet 

We target net leverage of $3.8 billion. At December 31, 2017, our leverage of $3.9  billion was above this target due to the timing of the three 

apartment community sales discussed above that closed in January 2018. 

Our leverage includes our share of long-term, non-recourse property debt encumbering apartment communities in our Real Estate portfolio, our 
term loan, outstanding borrowings on the revolving credit facility and outstanding preferred equity. In our calculation of leverage, we exclude non-
recourse property debt obligations of consolidated partnerships served by our Asset Management business, as these are not our obligations and 
they have limited effect on the amount of fees and other amounts we expect to receive in our role as asset manager for these partnerships. 

Our  leverage  strategy  seeks  to  increase  financial  returns  while  using  leverage  with  appropriate  caution.  We  limit  risk  through  balance  sheet 
structure, employing low leverage, primarily non-recourse and long-dated property debt; build financial flexibility by maintaining ample unused and 
available credit as well as holding properties with substantial value unencumbered by property debt; and use partners’ capital when it enhances 
financial returns or reduces investment risk. 

We  target  the  ratio  of  Proportionate  Debt  and  Preferred  Equity  to  Adjusted  EBITDA  to  be  below  7.0x  and  we  target  the  ratio  of  Adjusted 

EBITDA to Adjusted Interest Expense and Preferred Dividends to be greater than 2.5x.  

Proportionate Debt, Adjusted EBITDA and Adjusted Interest Expense, as used in these ratios, are non-GAAP financial measures, which are 
further discussed and reconciled under the Non-GAAP Measures – Leverage Ratios heading. Preferred Equity represents Aimco’s preferred stock 
and the Aimco Operating Partnership’s preferred OP Units. Our leverage ratios for the three months ended December 31, 2017, are presented below:

Table of Contents 

We  calculate  our  leverage  ratios  based  on  the  most  recent  three  month  amounts,  annualized.  Our  calculation  of  Adjusted  EBITDA  in  our 
leverage ratios has been adjusted on a pro forma basis to reflect the disposition of five apartment communities during the period as if the sales had 
closed on October 1, 2017. The effect of this pro forma adjustment may be found in the Adjusted EBITDA reconciliation under the Non-GAAP 
Measures heading.  

During 2017, we closed or rate-locked nine fixed-rate, non-recourse, amortizing, property loans totaling $550.8 million. On a weighted basis, the 
term of these loans averaged 9.1 years and their interest rates averaged 3.48%, 123 basis points above the corresponding treasury rates at the time 
of pricing. 

Also during 2017, we restructured five fixed-rate, non-recourse, amortizing, property loans totaling $17.4 million, extending their maturity dates 

from 2018 to 2023 and reducing their weighted average interest rate from 4.13% to 3.63%. 

The net effect of 2017 property debt refinancing activities has been to lower our weighted average fixed interest rates by about 20 basis points to 

4.64%, generating prospective annual interest savings of approximately $6.6 million. 

Our liquidity consists of cash balances and available capacity on our revolving line of credit. As of December 31, 2017, we had on hand $616.6 

million of cash and restricted cash plus available capacity on our revolving line of credit. 

We also manage our financial flexibility by maintaining an investment grade rating and holding apartment communities that are unencumbered 
by property debt. At December 31, 2017, we held unencumbered apartment communities with an estimated fair market value of approximately $1.8 
billion, up 12.5% year-over-year. 

Two credit rating agencies rate our creditworthiness, using different methodologies and ratios for assessing our credit, and both have rated our 
credit and outlook as BBB- (stable), an investment grade rating. Although some of the ratios they use are similar to those we use to measure our 
leverage, there are differences in our methods of calculation and therefore our leverage ratios disclosed above are not indicative of the ratios that 
may be calculated by these agencies. 

For additional information regarding our leverage, please see the discussion under the Liquidity and Capital Resources heading.  

Team and Culture 

Our team and culture are keys to our success. Our intentional focus on a collaborative and productive culture based on respect for others and 
personal responsibility is reinforced by a preference for promotion from within based on succession planning and talent development to produce a 
strong, stable team that is the enduring foundation of our success. In 2017, Aimco was recognized by the Denver Post as a Top Work Place. We are 
one of only a dozen Colorado companies of all sizes that have earned this designation for five consecutive years. 

Key Financial Indicators 

The  key  financial  indicators  that  we  use  in  managing  our  business  and  in  evaluating  our  operating  performance  are  Economic  Income,  our 
measure  of  total  return,  and  Adjusted  Funds  From  Operations,  our  measure  of  current  return.  In  addition  to  these  indicators,  we  evaluate  our 
operating performance and financial condition using: Pro forma Funds From Operations; FCF; same store property operating results; proportionate 
property  net  operating  income;  average  revenue  per  effective  apartment  home;  leverage  ratios;  and  net  leverage.  Certain  of  these  financial 
indicators are non-GAAP financial measures, which are defined, further described and, for certain of the measures, reconciled to comparable GAAP-
based measures under the Non-GAAP Measures heading below. 

Results of Operations 

Because our operating results depend primarily on income from our apartment communities, the supply of and demand for apartments influences 
our operating results. Additionally, the level of expenses required to operate and maintain our apartment communities and the pace and price at 
which we redevelop, acquire and dispose of our apartment communities affect our operating results.  

The  following  discussion  and  analysis  of  the  results  of  our  operations  and  financial  condition  should  be  read  in  conjunction  with  the 

accompanying consolidated financial statements in Item 8.  

Overview 

2017 compared to 2016  

Net income attributable to Aimco and net income attributable to the Aimco Operating Partnership decreased by $114.6 million and $120.0 million, 

respectively, for the year ended December 31, 2017 as compared to 2016. The decrease in income was  

24 

 
 
Table of Contents 

principally  due  to  a  decrease  in  gain  on  dispositions  of  real  estate  and  an  increase  in  depreciation  and  amortization  resulting  from  redeveloped 
apartment homes placed into service and the completion of One Canal and the acquisition of Indigo in 2016, partially offset by improved operating 
results as further described below. 

2016 compared to 2015  

Net income attributable to Aimco and net income attributable to the Aimco Operating Partnership increased by $181.7 million and $190.8 million, 
respectively, for the  year ended December 31, 2016  as  compared  to  2015.  The  increase  in  income  was  principally  due  to  an  increase  in  gain  on 
dispositions of real estate, partially offset by an increase in depreciation and amortization resulting from redeveloped apartment homes placed into 
service and the completion of One Canal and the acquisition of Indigo in 2016. 

The following paragraphs discuss these and other items affecting the results of operations of Aimco and the Aimco Operating Partnership in 

more detail. 

Property Operations 

As described under the preceding Executive Overview heading, our Real Estate segment consists primarily of market rate apartment communities 

in which we hold a substantial equity ownership interest. 

We use proportionate property net operating income to assess the operating performance of our Real Estate portfolio. Proportionate property 
net operating income reflects our share of rental and other property revenues less direct property operating expenses, including real estate taxes, for 
consolidated apartment communities we manage. Accordingly, the results of operations of our Real Estate segment discussed below are presented 
on a proportionate basis and exclude the results of four apartment communities with 142 apartment homes that we neither manage nor consolidate. 

We do not include offsite costs associated with property management or casualty-related amounts in our assessment of segment performance. 
Accordingly, these items are not allocated to our segment results discussed below. Refer to Note 12 in the consolidated financial statements in Item 
8 for further discussion regarding our reportable segments, including a reconciliation of these proportionate amounts to consolidated rental and 
other property revenues and property operating expenses. 

Real Estate Proportionate Property Net Operating Income 

We classify apartment communities within our Real Estate segment as Same Store and Other Real Estate. Same Store communities are those that 
have reached a stabilized level of operations as of the beginning of a two-year comparable period and maintained it throughout the current and 
comparable prior year, and are not expected to be sold within 12 months. Other Real Estate includes apartment communities that do not meet the 
Same  Store  definition,  including,  but  not  limited  to:  redevelopment  and  development  apartment  communities,  which  are  those  currently  under 
construction that have not achieved a stabilized level of operations and those that have been completed in recent years that have not achieved and 
maintained  stabilized  operations  for  both  the  current  and  comparable  prior  year;  acquisition  apartment  communities,  which  are  those  we  have 
acquired since the beginning of a two-year comparable period; and communities that we expect to sell within 12 months but do not yet meet the 
criteria to be classified as held for sale. 

As of December 31, 2017, as defined by our segment performance metrics, our Real Estate segment consisted of 92 Same Store communities with 

26,386 apartment homes and 37 Other Real Estate communities with 9,863 apartment homes. 

From December 31, 2016 to December 31, 2017, on a net basis, our Same Store portfolio decreased by nine communities and decreased by 4,507 

apartment homes. These changes consisted of: 

• 

• 

• 

• 

• 

• 

the addition of three redeveloped apartment communities with 974 apartment homes that were classified as Same Store upon maintaining 
stabilized operations for the entirety of both periods presented; 

the  addition  of  one  acquired  apartment  community  with  94  apartment  homes  that  was  classified  as  Same  Store  because  we  have  now 
owned it for the entirety of both periods presented; 

the reduction of five apartment communities with 2,460 apartment homes for which we commenced redevelopment during the period; 

the reduction of two apartment communities with 906 apartment homes we expected to sell during 2017; 

the reduction of three apartment communities with 1,696 apartment homes sold during the period; and

the reduction of three apartment communities with 513 apartment homes held for sale.

For the year ended December 31, 2017 compared to 2016, our Real Estate segment’s proportionate property net operating income increased $49.4 

million, or 9.1%. 

Same Store proportionate property net operating income increased by $16.8 million, or 4.2%. This increase was primarily attributable to an $18.0 
million, or  3.2%, increase in rental and other property revenues due to  higher average revenues ($59 per effective home), comprised primarily of 
increases in rental rates. Renewal rents (the rent paid by an existing resident who renewed her lease compared to the rent she previously paid) were 
up 4.6% for the year ended December 31, 2017, and new lease rents (the rent paid by a new resident compared to the rent paid by the previous 
resident of the same apartment home) were up 0.6%, resulting in a weighted average increase of 2.5%. The increase in Same Store rental and other 
property revenues was partially offset by a $1.2 million, or 0.7%, increase in property operating expenses, primarily due to increases in real estate 
taxes. During the year ended December 31, 2017 compared to 2016, controllable operating expenses, which exclude utility costs, real estate taxes and 
insurance, decreased by $1.0 million, or 1.3%. 

The proportionate property net operating income of Other Real Estate communities increased by $32.5 million, or 23.8%, due to: 

• 

• 

redevelopment  and  lease-up  activities  during  the  year  ended  December  31,  2017,  which  helped  contribute  to  incremental  property  net 
operating income of $20.9 million compared to 2016; and  

higher property net operating income of $11.6 million from other communities, including the effect of our increased ownership interest in 
the Palazzo communities from our June 2017 reacquisition of the 47% limited partner interest in the related joint venture.

For the year ended December 31, 2016 compared to 2015, our Real Estate segment’s proportionate property net operating income increased $43.7 

million, or 8.8%. 

Same Store proportionate property net operating income increased by $25.6 million, or 6.4%. This increase was primarily attributable to a $27.5 
million, or  4.8%, increase in rental and other property revenues due to  higher average revenues ($85 per effective home), comprised primarily of 
increases in rental rates. Renewal rents (the rent paid by an existing resident who renewed her lease compared to the rent she previously paid) were 
up 5.7% for the year ended December 31, 2016, and new lease rents (the rent paid by a new resident compared to the rent paid by the previous 
resident of the same apartment home) were up 2.4%, resulting in a weighted average increase of 4.0%. The increase in Same Store rental and other 
property revenues was partially offset by a $1.9 million, or 1.1%, increase in property operating expenses, primarily due to increases in real estate 
taxes,  personnel  costs  and  repairs  and  maintenance,  partially  offset  by  lower  utilities  expenses  and  insurance  costs.  During  the  year  ended 
December 31, 2016 compared to 2015, controllable operating expenses, which exclude utility costs, real estate taxes and insurance, increased by $1.4 
million, or 1.7%. 

The proportionate property net operating income of Other Real Estate communities increased by $18.0 million during the year ended December 

31, 2016 compared to 2015. This increase is attributable to the following: 

• 

• 

• 

$7.8 million increase due to the net operating income stabilization of three redeveloped communities;

$3.7  million  due  to  lease-up  activities  at  acquired  and  redeveloped  apartment  communities,  partially  offset  by  decreases  due  to 
apartment homes taken out of service for redevelopment; and 

$6.5 million from other communities, including apartment communities we acquired in 2015 and market rate increases at four apartment 
communities that were approved in 2016 by the Department of Housing and Urban Development.

Non-Segment Real Estate Operations 

Operating  income  amounts  not  attributed  to  our  Real  Estate  segment  include  offsite  costs  associated  with  property  management,  casualty 
losses, and the results of apartment communities sold or held for sale, reported in consolidated amounts, which we do not allocate to our Real 
Estate segment for purposes of evaluating segment performance (see Note 12 to the consolidated financial statements in Item 8).  

For the years ended December 31, 2017, 2016 and 2015, casualty losses totaled $8.2 million, $5.6 million and $7.0 million, respectively. Casualty 
losses were elevated during the year ended December 31, 2017, primarily due to hurricane damage. Casualty losses were elevated during the year 
ended December 31, 2015, primarily due to losses resulting from property damage and snow removal costs associated with the severe snow storms 
in the Northeast.  

For the years ended December 31, 2017, 2016 and 2015, apartment communities previously in our Real Estate portfolio that were sold or classified 

as held for sale as of December 31, 2017 generated net operating income of $26.5 million, $46.8 million and $68.8 million, respectively. 

Asset Management Results 

As further discussed in Note 2 to the consolidated financial statements in Item 8, we provide asset management and other services to certain 
consolidated partnerships that own apartment communities that qualify for low-income housing tax credits and are structured to provide for the 
pass-through of tax credits and tax deductions to their partners. 

Contribution from Asset Management included in our consolidated financial statements includes: fees and other amounts paid to us from the net 
operating  income  of  partnerships  served  by  our  Asset  Management  business  less  interest  expense  incurred  on  non-recourse  property  debt 
obligations of the partnerships; income associated with delivery of tax credits to the third-party investors in the partnerships (including amounts 
received  during  the  period  and  amounts  received  in  previous  periods);  and  transactional  revenue  and  other  income  less  asset  management 
expenses (including certain allocated offsite costs related to the operation of this business). 

The contribution from Asset Management for the years ended December 31, 2017, 2016 and 2015, is presented in the table below.

For the periods presented above, the contribution from the Asset Management business fluctuated for the reasons discussed below. 

• 

• 

• 

Increases  in  the  amount  available  for  payment  of  Asset  Management  fees  generated  by  the  partnerships  were  primarily  attributed  to 
increases  in  rental  income  due  to  higher  rates,  partially  offset  by  the  loss  of  net  operating  income  from  communities  sold  and  higher 
operating expenses, including personnel and repairs and maintenance costs. 

Tax credit income, net, decreased primarily due to the delivery of substantially all of the tax credits on various partnerships and our 2016 
acquisition of an investor limited partner’s interest in one of the tax credit partnerships (and their rights to undelivered tax credits) prior to 
the end of the tax credit delivery period. Following the purchase, we recognized tax benefits in our results of operations, which largely 
offset the tax credit income we otherwise would have recognized. 

Transactional revenues for the year ended December 31, 2017 includes $2.4 million in fees earned in connection with the disposition of real 
estate and for the year ended December 31, 2016 includes a $3.6 million fee earned for assisting a third-party property owner in a mark-up-
to-market renewal related to an affordable community we previously owned. Other income, for each of the years presented, includes results 
related to the Napico business, which is further described under the Other, net heading below.  

28 

 
 
  
  
  
  
  
  
Table of Contents 

We expect the contribution to our net income from the Asset Management business to decline in future years as we continue to deliver the final 
tax credits for these partnerships and, as part of our plan to exit the Asset Management business, the partnerships sell the underlying apartment 
communities.  

Depreciation and Amortization 

For  the  year  ended December  31,  2017  compared  to  2016,  depreciation  and  amortization  expense  increased  by  $33.1  million  primarily  due  to 
renovated  apartment  homes  placed  in  service  after  their  completion,  a  full  year  of  depreciation  following  the  2016  completion  of  our  One  Canal 
development and 2016 acquisition of Indigo, and other capital additions, partially offset by decreases associated with apartment communities sold.  

For  the  year  ended  December 31,  2016  compared  to  2015,  depreciation  and  amortization  expense  increased  by  $26.8  million  primarily  due  to 
renovated  apartment  homes  placed  in  service  after  their  completion,  the  completion  of  our  One  Canal  and  Vivo  developments,  and  our  2016 
acquisition of Indigo and other capital additions, partially offset by decreases associated with apartment communities sold. 

General and Administrative Expenses 

In recent years, we have worked toward simplifying our business, which allowed us to reduce overhead and other costs. This simplification and 
our  scale  reductions  have  allowed  us  to  reduce  our  offsite  costs,  which  consist  of  general  and  administrative  expenses,  property  management 
expenses and investment management expenses, by $11.6 million, or 15.1%, over the last three years.  

For  the year  ended  December  31,  2017 compared to  2016,  general  and  administrative  expenses decreased  $3.1 million,  primarily  due  to  lower 

personnel and related costs including incentive compensation, professional services, technology costs and other corporate costs. 

For the year ended December 31, 2016 compared to 2015, general and administrative expenses, excluding incentive compensation, decreased by 
approximately  $0.2  million.  Inclusive  of  incentive  compensation,  general  and  administrative  expenses  increased $0.5  million, primarily due to our 
performance against key performance indicators in 2016 as compared to 2015. 

Other Expenses, Net 

Other  expenses,  net  includes  franchise  taxes,  costs  associated  with  our  risk  management  activities,  partnership  administration  expenses  and 

certain non-recurring items.  

For the year ended December 31, 2017 compared to 2016, other expenses, net decreased by $2.9 million. The decrease was primarily due to the 
2016  recognition  of  estimated  future  environmental  clean-up  and  abatement  costs  associated  with  the  matters  discussed  in  Note  5  to  the 
consolidated financial statements in Item 8, partially offset by legal costs we incurred related to a challenge to the title of a property we acquired in 
2014. 

For the year ended December 31, 2016 compared to 2015, other expenses, net increased by $3.9 million. The increase was primarily due to the 

2016 environmental costs discussed above, partially offset by lower legal and related costs. 

Provision for Real Estate Impairment Loss 

In January 2018, we agreed to sell our interests in the entities owning the La Jolla Cove property in settlement of legal actions filed in 2014 by a 
group of disappointed buyers who had hoped to acquire the property. As a result of the settlement, we recognized in our 2017 results a gross 
impairment  loss  of  $35.8  million,  $25.6  million  of  which  relates  to  the  establishment  of  a  deferred  tax  liability  assumed  in  connection  with  our 
acquisition of the business entities. Upon closing of the transaction, the tax liability will be assumed by the buyer, resulting in no economic loss to 
Aimco. The remaining  $10.2  million  loss  is  offset  by  cash  distributions  paid  to  us  during  our  ownership  and  avoided  legal  costs  for  continued 
litigation. On an economic basis, we agreed to sell these entities at roughly our purchase price, adjusted for retained cash distributions and avoided 
legal costs. 

We recognized no provisions for impairment losses during the years ended December 31, 2016 or 2015. 

Interest Expense 

For  the  year  ended  December  31,  2017  compared  to  2016,  interest  expense,  which  includes  the  amortization  of  debt  issuance  costs  and 
amortization of deferred financing costs, decreased by $1.8 million, or 0.9%. The decrease was primarily due to lower average outstanding balances 
on non-recourse property debt for our Real Estate apartment communities and lower interest rates, resulting in an $11.9 million reduction in interest 
expense. These decreases were partially offset by higher amounts outstanding on corporate borrowings (including our term loan and incremental 
line borrowings used to temporarily fund the reacquisition of  

29 

 
 
Table of Contents 

the Palazzo limited partner interests) and a decrease in capitalized interest associated with our redevelopment and development activities. 

For  the  year  ended  December  31,  2016  compared  to  2015,  interest  expense  decreased  by  $3.3  million,  or  1.7%.  The  decrease  was  primarily 
attributed to lower average outstanding balances from our repayment of non-recourse property debt and to a lesser extent from a lower average cost 
of  debt  on  property  loans  refinanced  during  the  year,  resulting  in  an  $8.1  million  reduction  in  interest  expense,  and  a  $4.9  million  reduction  of 
interest expense on debt related to apartment community dispositions. These decreases were partially offset by increased interest expense on debt 
associated  with  apartment  community  acquisitions  and  on  One  Canal,  the  construction  of  which  was  completed  during  2016  and  for  which  we 
ceased interest capitalization, and higher average borrowings on our revolving credit facility. 

Other, Net 

Other,  net  includes  our  equity  in  the  income  or  loss  of  unconsolidated  real  estate  partnerships,  and  the  results  of  operations  related  to  the 

Napico business, which we accounted for under the profit sharing method prior to the derecognition of the final property during 2017.  

For  the  year  ended  December  31,  2017  compared  to 2016,  net  income  of  the  Napico  business  increased  by  $2.1  million. For the  year  ended 
December  31,  2016 compared to 2015, net income of the Napico business increased  by $5.4  million. As discussed in Note  3 to the consolidated 
financial  statements  in  Item  8,  in  2017  we  derecognized  the  assets  and  liabilities  related  to  the  final  Napico  property,  and  in  2016  we  partially 
derecognized the assets and liabilities of the Napico business, resulting in gains that contributed to the increase in other, net in both years. 

Income Tax Benefit 

Certain of our operations, including property management and risk management, are conducted through TRS entities. Additionally, some of our 

apartment communities are owned through TRS entities. 

Our  income  tax  benefit  calculated  in  accordance  with  GAAP  includes:  (a)  historic  tax  credits  that  offset  income  tax  obligations  of  our  TRS 
entities;  (b)  income  taxes  associated  with  the  income  or  loss  of  our  TRS  entities,  for  which  the  tax  consequences  have  been  realized  or  will  be 
realized in future periods; and (c) low income housing tax credits that offset REIT taxable income, primarily from retained capital gains. Income taxes 
related to these items (before gains on dispositions) are included in income tax benefit in our consolidated statements of operations. 

Income tax benefit for the periods presented also reflects GAAP taxes associated with income and gains related to the Napico business, which 

was partially deconsolidated in 2016 and for which the final property was deconsolidated in 2017. 

For the  year ended December 31, 2017 compared to 2016, income tax benefit increased  by $6.9 million,  from $25.2 million to  $32.1 million. The 
increase is primarily due to higher tax benefit associated with low-income housing tax credits from our September 2016 acquisition of the limited 
partner interests in a tax credit partnership, higher net operating losses at the TRS entities (including the La Jolla Cove impairment loss discussed 
above) and the $0.5 million net tax benefit we recognized as a result of the December 2017 tax reform legislation (as further discussed in Note 9 to the 
consolidated  financial  statements  in  Item  8).  These  increases  were  partially  offset  by  a  decrease  in  historic  tax  credits  associated  with  the 
redevelopment of certain apartment communities, including the timing of final certification on one redevelopment in 2016. 

For  the  year  ended  December  31,  2016  compared  to  2015,  income  tax  benefit  decreased  by  $2.3  million,  primarily  due  to  lower  net  losses 
recognized by apartment communities owned by our TRS entities, partially offset by higher historic tax credits associated with the redevelopment of 
certain  apartment  communities  and  higher  tax  benefit  associated  with  low-income housing tax credits from our acquisition of the limited partner 
interests in a tax credit partnership.

The apartment communities sold from our Real Estate portfolio during 2017, 2016 and 2015 were primarily located outside of our primary markets 
or in lower-rated  locations  within  our  primary  markets  and  had  average  revenues  per  apartment  home  significantly  below  those  of  our  retained 
portfolio.  

Noncontrolling Interests in Consolidated Real Estate Partnerships 

Noncontrolling interests in consolidated real estate partnerships reflects the results of our consolidated real estate partnerships allocated to the 
owners who are not affiliated with Aimco. The amounts of income or loss of our consolidated real estate partnerships that we allocate to owners not 
affiliated with Aimco include their share of property management fees, interest on notes and other amounts that we charge to these partnerships.  

For the years ended December  31,  2017, 2016 and 2015, we allocated net income of $9.1 million,  $25.3 million, and $4.8 million, respectively, to 
noncontrolling interests in consolidated real estate partnerships. The amount of net income allocated to noncontrolling interests was driven by 
three primary factors: the operations of the consolidated apartment communities; gains on the sale of apartment communities with noncontrolling 
interest holders; and the results of operations of the Napico business, as further discussed below. 

• 

The amount of net income allocated to noncontrolling interests resulting from operations of the consolidated apartment communities was 
$2.4 million, $4.4  million and $4.2 million for the years ended December 31, 2017,  2016 and 2015, respectively. The decrease from 2016 to 
2017 is primarily due to the June 30, 2017 reacquisition of our limited partner’s interest in the Palazzo joint venture. 

•  Gains on the sale of apartment communities allocated to noncontrolling interests totaled $7.3 million, $13.0 million and $6.0 million for the 

years ended December 31, 2017, 2016 and 2015, respectively. 

•  As discussed in Note 3 to the consolidated financial statements in Item 8, we derecognized the Napico business in two transactions, which 
occurred in 2016 and 2017. We allocated $8.1  million of the gain on sale and a $0.6 million net loss, respectively, to the noncontrolling 
interest holders in connection with the 2017 and 2016 transactions. In 2015, we allocated a net loss of  $5.4 million to the noncontrolling 
interest holders from the results of Napico operations.  

Net Income Attributable to Aimco Preferred Stockholders and the Aimco Operating Partnership’s Preferred Unitholders 

Net income attributable to Aimco preferred stockholders and the Aimco Operating Partnership’s preferred unitholders decreased by $3.4 million 
and  $2.9  million,  respectively,  during  the  year  ended  December  31,  2017  as  compared  to  2016.  These  decreases  were  primarily  due  to  Aimco’s 
redemption of its Class Z Preferred Stock in 2016. In connection with the redemption, we wrote off previously deferred issuance costs of $1.3 million. 
Additionally, the $0.7 million excess of the redemption value over the

carrying  amount  was  reflected  in  the  net  income  attributable  to  Aimco  Preferred  Stockholders  and  Aimco  Operating  Partnership’s  Preferred 
Unitholders for the year ended December 31, 2016.  

Net income attributable to Aimco preferred stockholders and the Aimco Operating Partnership’s preferred unitholders increased by $0.2 million 
and  $0.5  million,  respectively,  during  the  year  ended  December  31,  2016  as  compared  to  2015.  These  increases  were  primarily  due  to  Aimco’s 
redemption  of  its  Class  Z  Preferred  Stock  described  above,  which  resulted  in $2.0  million  of  redemption  related  charges,  partially  offset  by  $1.1 
million of lower dividends.  

Critical Accounting Policies and Estimates 

We prepare our consolidated financial statements in accordance with GAAP, which requires us to make estimates and assumptions. We believe 
that the following critical accounting policies involve our more significant judgments and estimates used in the preparation of our consolidated 
financial statements. 

Capitalized Costs 

We capitalize costs, including certain indirect costs, incurred in connection with our capital additions activities, including redevelopments and 
developments,  other  tangible  apartment  community  improvements  and  replacements  of  existing  apartment  community  components.  Included  in 
these capitalized costs are payroll costs associated with time spent by site employees in connection with the planning, execution and control of all 
capital additions activities at the apartment community level. We characterize as “indirect costs” an allocation of certain department costs, including 
payroll, at the area operations and corporate levels that clearly relate to capital additions activities. We also capitalize interest, property taxes and 
insurance  during  periods  in  which  redevelopments  and  developments  are  in  progress.  We  commence  capitalization  of  costs,  including  certain 
indirect costs, incurred in connection with our capital addition activities, at the point in time when activities necessary to get apartment communities 
ready for their intended use begin. These activities include when apartment communities or apartment homes are undergoing physical construction, 
as well as when apartment homes are held vacant in advance of planned construction, provided that other activities such as permitting, planning 
and design are in progress. We cease the capitalization of costs when the apartment communities or components thereof are substantially complete 
and ready for their intended use, which is typically when construction has been completed and apartment homes are available for occupancy. We 
charge  costs  including  ordinary  repairs,  maintenance  and  resident  turnover  costs  to  property  operating  expense,  as  incurred.  Refer  to  the 
discussion  of  investing  activities  within  the  Liquidity  and  Capital  Resources  section  for  a  summary  of  costs  capitalized  during  the  periods 
presented. 

Impairment of Long-Lived Assets 

Real  estate  and  other  long-lived  assets  to  be  held  and  used  are  stated  at  cost,  less  accumulated  depreciation  and  amortization,  unless  the 
carrying amount of the asset is not recoverable. If events or circumstances indicate that the carrying amount of an apartment community may not be 
recoverable, we make an assessment of its recoverability by comparing the carrying amount to our estimate of the undiscounted future cash flows, 
excluding interest charges, of the apartment community. If the carrying amount exceeds the estimated aggregate undiscounted future cash flows, we 
recognize an impairment loss to the extent the carrying amount exceeds the estimated fair value of the apartment community.  

As part of our portfolio strategy, we seek to sell up to 10% of our portfolio annually and to reinvest the proceeds from such sales in accretive 
uses such as capital enhancements, redevelopments, occasional developments, and selective acquisitions with projected Free Cash Flow internal 
rates of return higher than expected from the communities being sold. As we execute this strategy, we evaluate alternatives to sell or reduce our 
interest  in  apartment  communities  that  do  not  align  with  our  long-term  investment  strategy,  although  there  is  no  assurance  that  we  will  sell  or 
reduce  our  investment  in  such  apartment  communities  during  the  desired  time  frame.  For  any  apartment  communities  that  are  sold  or  meet  the 
criteria to be classified as held for sale during the next 12 months, the reduction in the estimated holding period for these apartment communities 
may result in impairment losses.  

Non-GAAP Measures 

Various of the key financial indicators we use in managing our business and in evaluating our financial condition and operating performance are 
non-GAAP  measures.  Key  non-GAAP  measures  we  use  are  defined  and  described  below,  and  for  those  non-GAAP financial measures used or 
disclosed  within  this  annual  report,  reconciliations  of  the  non-GAAP  financial  measures  to  the  most  comparable  financial  measure  computed  in 
accordance with GAAP are provided. 

Funds from Operations, Pro forma Funds From Operations and Adjusted Funds From Operations are non-GAAP financial measures, which are 
defined and further described below under the Funds From Operations and Adjusted Funds From Operations heading. Economic Income and Net 
Asset Value are non-GAAP financial measures defined and further described below under the Economic Income heading.

Table of Contents 

Free Cash Flow, or FCF, as calculated for our retained portfolio, represents an apartment community’s property net operating income, or NOI, 
less spending for capital replacements, which represents our estimation of the capital additions made to replace capital assets consumed during our 
ownership period (further discussed under the Funds From Operations and Adjusted Funds From Operations heading and the Liquidity and Capital 
Resources heading). FCF margin represents an apartment community’s NOI less $1,200 per apartment home of assumed annual capital replacement 
spending,  as  a  percentage  of  the  apartment  community’s  rental  and  other  property  revenues.  Capital  replacement  spending  is  a  method  of 
measuring the cost of capital asset usage during the period; therefore we believe that FCF is useful to investors as a supplemental measure of 
apartment community performance because it takes into consideration costs incurred during the period to replace capital assets that have been 
consumed during our ownership.  

Funds From Operations and Adjusted Funds From Operations 

Funds From Operations, or FFO, is a non-GAAP financial measure that we believe, when considered with the financial statements determined in 
accordance with GAAP, is helpful to investors in understanding our performance because it captures features particular to real estate performance 
by recognizing that real estate generally appreciates over time or maintains residual value to a much greater extent than do other depreciable assets 
such as machinery, computers or other personal property. The National Association of Real Estate Investment Trusts, or NAREIT, defines FFO as 
net  income  or  loss  computed  in  accordance  with  GAAP,  excluding  gains  from  sales  of,  and  impairment  losses  recognized  with  respect  to, 
depreciable real estate, plus depreciation and amortization related to real estate, and after adjustments for unconsolidated partnerships and joint 
ventures. Adjustments for unconsolidated partnerships and joint ventures are calculated on the same basis to determine FFO. We calculate FFO 
attributable to Aimco common stockholders (diluted) by subtracting, if dilutive, redemption or repurchase related preferred stock issuance costs 
and dividends on preferred stock.  

In addition to FFO, we compute Pro forma FFO and Adjusted FFO, or AFFO, which are also non-GAAP financial measures that we believe are 
helpful  to  investors  in  understanding  our  performance.  Pro  forma  FFO  represents  FFO  attributable  to  Aimco  common  stockholders  (diluted), 
excluding preferred equity redemption-related amounts (adjusted for noncontrolling interests). Preferred equity redemption-related amounts (gains 
or losses) are items that periodically affect our operating results and we exclude these items from our calculation of Pro forma FFO because such 
amounts are not representative of our operating performance. 

Additionally in 2017, we recognized a net tax benefit associated with the December 2017 tax reform legislation consisting of a benefit related to 
the revaluation of net deferred tax liabilities of Aimco’s taxable REIT subsidiaries, partially offset by a valuation allowance related to deferred tax 
assets. We excluded this net tax benefit from our computation of Pro forma FFO because this type of tax benefit occurs infrequently and is not 
representative of our operating performance.  

AFFO represents Pro forma FFO reduced by Capital Replacements (also adjusted for noncontrolling interests), which represents our estimation 
of the capital additions made to replace capital assets consumed during our ownership period. When we make capital additions at an apartment 
community, we evaluate whether the additions extend the useful life of an asset as compared to its condition at the time we purchased the apartment 
community. We classify as Capital Improvements those capital additions that meet these criteria and we classify as Capital Replacements those that 
do not. AFFO is a key financial indicator we use to evaluate our operational performance and is one of the factors that we use to determine the 
amounts of our dividend payments. 

FFO,  Pro  forma  FFO  and  AFFO  should  not  be  considered  alternatives  to  net  income  (loss),  as  determined  in  accordance  with  GAAP,  as 
indications of our performance. Although we use these non-GAAP measures for comparability in assessing our performance compared to other 
REITs, not all REITs compute these same measures and those who do may not compute them in the same manner. Additionally, computation of 
AFFO is subject to our definition of Capital Replacement spending. Accordingly, there can be no assurance that our basis for computing these non-
GAAP measures is comparable with that of other REITs.

(1)  Represents  the  numerator  for  calculating  Aimco’s  earnings  per  common  share  in  accordance  with  GAAP  (see  Note  10  to  the  consolidated  financial 

statements in Item 8). 

(2)  During  the  years  ended  December 31, 2017,  2016 and  2015,  the  Aimco  Operating  Partnership  had  outstanding,  on  average, 7,422,334,  7,760,597 and 

7,656,626 common OP Units. 

(3)  Represents the denominator for Aimco’s earnings per common share – diluted, calculated in accordance with GAAP.

Refer to the Executive Overview for discussion of our Pro forma FFO and AFFO results for 2017, as compared to their comparable periods in 

2016. 

Refer  to  the  Liquidity  and  Capital  Resources  section  for  further  information  regarding  our  capital  investing  activities,  including  Capital 

Replacements. 

The Aimco Operating Partnership does not separately compute or report FFO, Pro forma FFO or AFFO. However, based on Aimco’s method for 
allocation of such amounts to noncontrolling interests in the Aimco Operating Partnership, as well as the limited differences between Aimco’s and 
the Aimco Operating Partnership’s net income amounts during the periods presented, FFO, Pro forma FFO and AFFO amounts on a per unit basis 
for the Aimco Operating Partnership would be expected to be substantially the same as the corresponding per share amounts for Aimco. 

Economic Income 

Economic Income represents stockholder value creation as measured by the change in estimated NAV per share plus cash dividends per share. 
We believe Economic Income is important to investors as it represents a measure of the total return we have earned for our stockholders. NAV, as 
used in our calculation of Economic Income, is a non-GAAP measure and represents the estimated fair value of assets net of liabilities attributable 
to Aimco’s common stockholders and the Aimco Operating Partnership’s common unitholders on a diluted basis. We believe NAV is considered 
useful by some investors in real estate companies because the value of company assets can be readily estimated, even for non-earning assets such 
as land or properties under development. NAV has the advantage of incorporating the investment decisions of thousands of real estate investors. 
We believe it enhances comparability among companies that have differences in their accounting. While NAV is not identical to liquidation value in 
that some costs and benefits are disregarded, it is often considered a floor with upside for value ascribed to the operating platform.

Table of Contents 

NAV also provides an objective basis for the perceived quality and predictability of future cash flows as well as their expected growth as these are 
factors considered by real estate investors.  

Our estimated NAV per share and the quoted share price of Aimco Common Stock are not necessarily equal. Although we use Economic Income 
and NAV for comparability in assessing our value creation compared to other REITs, not all REITs publish these measures and those who do may 
not compute them in the same manner. Accordingly, there can be no assurance that our basis for computing these measures is comparable with that 
of other REITs. 

We report NAV on a semiannual basis, as of the end of the first and third quarters. Economic Income for 2017, was calculated using the change 
in  NAV  per  share  between  September  30,  2016  and  2017.  NAV  will  fluctuate  over  time.  This  NAV  information  should  not  be  relied  upon  as 
representative of the amount a stockholder could expect to receive in a liquidation event, now or in the future. Certain assets are excluded as are 
certain  liabilities  such  as  taxes  and  transaction  costs  associated  with  a  liquidation.  In  addition,  NAV  is  based  on  management’s  subjective 
judgments, assumptions and opinions as of the date of determination. We assume no obligation to revise or update NAV to reflect subsequent or 
future  events  or  circumstances.  Our  NAV  estimate  is  subject  to  a  variety  of  risks  and  uncertainties,  many  of  which  are  beyond  our  control, 
including, without limitation, those described in Item 1A. Risk Factors.  

A reconciliation of NAV to Aimco’s total equity, which we believe is the most directly comparable GAAP measure, as of September 30, 2017, is 

provided below (in millions, except per share data):

(1)   We compute NAV by estimating the value of our communities, using methods we believe are appropriate based on the characteristics of the communities. 
For purposes of estimating NAV, real estate at fair value disclosed above includes wholly owned apartment communities plus our proportionate share of 
communities held by non-wholly owned entities (both consolidated and unconsolidated), and excludes the estimated fair value of communities that are part 
of the Asset Management business. The value of Asset Management communities is factored into the valuation of the Asset Management portfolio as 
described in footnote 5. A reconciliation of our consolidated apartment communities to those communities included in total real estate at fair value in the 
table above is as follows: 

Consolidated apartment communities as of September 30, 2017

For valuation purposes at September 30, 2017, we segregated these 141 communities into the following categories: stabilized portfolio and non-

stabilized portfolio.  

(2)  As  of  September  30, 2017,  our  stabilized  portfolio  includes  123  communities  that  had  reached  stabilized  operations  and  were  not  expected  to  be  sold 
within twelve months. We value this portfolio using a direct capitalization rate method based on the annualized proportionate property NOI for the three 
months ended September 30, 2017, less a 2% management fee. Market property management fees range between 1.5% and 3.0% with larger, higher quality 
portfolios at the lower end of that range. The weighted average estimated capitalization rate as applied to the annualized property NOI was 5.1%, which 
we calculate on a property-by-property basis, based

primarily on information published by a third-party. Community characteristics that we use to determine comparable market capitalization rates include: 
the  market  in  which  the  community  is  located;  infill  or  suburban  location  within  the  market;  property  quality  grade;  and  whether  the  community  is 
stabilized or value-add. We used this valuation method for approximately 79% of real estate fair value at September 30, 2017.  

(3)  The non-stabilized portfolio includes seven apartment communities under redevelopment at September 30, 2017 and two apartment communities in lease-
up. We valued these communities by discounting projected future cash flows. Key assumptions used to estimate the value of these communities include: 
revenues, which are based on in-place rents, projected submarket rent growth to community stabilization based on projections published by third parties 
and adjusted for the impacts of redevelopment; expenses, which are based on estimated operating costs adjusted for inflation and a management fee equal 
to 2% of projected revenue; estimated remaining costs to complete construction; and a terminal value based on current market capitalization rates plus five 
basis points per year from September 30, 2017 to community stabilization. Discount rates applied to estimated future cash flows of these communities 
ranged  between  6.00%  and  7.15%  depending  on  construction  and  lease-up progress. We used this valuation method for approximately 17% of the real 
estate fair value at September 30, 2017. The non-stabilized portfolio also included nine apartment communities under contract for sale, which were valued 
at sales contract price and represent approximately 4% of real estate fair value at September 30, 2017.  

(4)  We calculate the fair value of indebtedness related to real estate as the carrying value of our non-recourse property debt adjusted for the mark-to-market 
liability  on  our  fixed-rate  property  debt  as  of  September  30, 2017,  plus  the  outstanding  balances  on  the  revolving  line  of  credit  and  term  loan,  which 
approximate their fair value as of September 30, 2017.  The  mark-to-market has been computed using a money-weighted average interest rate of 4.15%, 
which  rate  takes  into  account  the  timing  of  amortization  and  maturities,  and  a  market  rate  of  3.75%,  which  rate  takes  into  account  the  duration  of  the 
existing property debt, the loan-to-value and debt service coverage, as well as timing of amortization and maturities. For purposes of estimating NAV, the 
fair value of debt includes our proportionate share of debt related to non-wholly owned entities (both consolidated and unconsolidated), and excludes non-
recourse  property  debt  obligations  of  consolidated  partnerships  of  the  Asset  Management  business,  which  is  factored  into  the  valuation  of  the  Asset 
Management business as described in footnote 5.  

(5)  We estimate our share of the fair value of the Asset Management business as the present value of the expected future cash flows of various low-income 
housing tax credit partnerships using a 7% discount rate. As further discussed in Note 2 to the consolidated financial statements in Item 8, the future cash 
flows we expect to receive include fees and other amounts to be paid from cash flows from the operation of the underlying communities and proceeds from 
sale of the underlying communities after repayment of any associated property-level debt. The key assumptions used to estimate the future cash flows we 
expect to receive include: operating cash flow, which is based on an estimate of contractual rents and expenses reflecting expected increases; the value of 
the  underlying  apartment  communities,  which  we  value  using  a  direct  capitalization  rate  method  similar  to  that  described  in  footnote  2  above;  and  the 
estimated sale date of the apartment communities, which is generally upon or shortly after the expiration of the tax credit compliance periods. 

(6)  Other  tangible  assets  consist  of  cash,  restricted  cash,  accounts  receivable  and  other  assets  for  which  we  reasonably  expect  to  receive  cash  through  the 
normal course of operations or another future event. Other tangible liabilities consist of accounts payable, accrued liabilities and other tangible liabilities we 
reasonably  expect  to  settle  in  cash  through  the  normal  course  of  operations  or  another  future  event.  Other  tangible  assets  and  liabilities  were  generally 
valued at their carrying amounts and reduced by the noncontrolling interests’ portion of these amounts and exclude intangible assets and liabilities reflected 
on  our  consolidated  balance  sheet.  The  fair  value  of  our  preferred  stock  is  estimated  as  the  closing  share  price  on  September  30,  2017,  less  accrued 
dividends. Such accrued dividends are assumed to be accounted for in the closing share price and these amounts are also included in other tangible liabilities. 

(7)  Total shares, units and dilutive share equivalents represents Common Stock, OP Units, participating unvested restricted shares and the dilutive effect of 

common stock equivalents outstanding as of September 30, 2017.  

Leverage Ratios 

As discussed under the Balance Sheet and Liquidity heading, as part of our leverage strategy, we target the ratio of Proportionate Debt and 
Preferred Equity to Adjusted EBITDA to be below 7.0x and we target the ratio of Adjusted EBITDA to Adjusted Interest Expense and Preferred 
Dividends to be greater than 2.5x. We believe these ratios are important measures as they are commonly used by investors and analysts to assess 
the relative financial risk associated with balance sheets of companies within the same industry, and they are believed to be similar to measures 
used by rating agencies to assess entity credit quality.  

We calculate our leverage ratios based on the most recent three month amounts, annualized. 

Proportionate Debt, as used in our leverage ratios, is a non-GAAP measure and includes our share of the long-term, non-recourse property debt 
secured  by  apartment  communities  in  the  Real  Estate  portfolio,  our  term  loan,  and  outstanding  borrowings  under  our  revolving  credit  facility, 
reduced by our share of the cash and restricted cash of our consolidated and unconsolidated partnerships owning communities in our Real Estate 
portfolio, and also by our investment in the subordinate tranches of a securitization trust that holds certain of our property debt (essentially, an 
investment in our own non-recourse property loans).  

In our Proportionate Debt computation, we increase our recorded debt by unamortized debt issue costs because these amounts represent cash 
expended in earlier periods and do not reduce our contractual obligations, and we reduce our recorded debt obligations by the amounts of cash and 
restricted cash on-hand (such restricted cash amounts being primarily restricted under the terms of  

36 

 
 
Table of Contents 

our property debt agreements) assuming these amounts would be used to reduce our outstanding leverage. We further reduce our recorded debt by 
the value of our investment in a securitization trust that holds certain of our property debt, as our payments of principal and interest associated with 
such property debt will ultimately repay our investments in the trust.  

We  exclude  from  our  leverage  the  non-recourse  property  debt  obligations  of  consolidated  partnerships  served  by  our  Asset  Management 
business. The non-recourse property debt obligations of these partnerships are not our obligations and have limited effect on the amount of fees 
and other payments we expect to receive. 

We believe Proportionate Debt is useful to investors as it is a measure of our net exposure to debt obligations. Proportionate Debt, as used in 

our leverage ratios, is calculated as set forth in the table below.  

Preferred  Equity,  as  used  in  our  leverage  ratios,  represents  the  redemption  amounts  for  Aimco’s  preferred  stock  and  the  Aimco  Operating 

Partnership’s preferred OP Units. Preferred Equity, although perpetual in nature, is another component of our overall leverage. 

Adjusted EBITDA is a non-GAAP measure. We believe Adjusted EBITDA provides investors relevant and useful information because it allows 
investors to view income from our operations on an unleveraged basis, before the effects of taxes, depreciation and amortization, gains or losses on 
sales of and impairment losses related to real estate and various other items described below.  

Adjusted EBITDA represents Aimco’s share of the consolidated amount of our net income, adjusted to exclude the effect of the following items 

for the reasons set forth below:  

•  Adjusted Interest Expense, defined below, to allow investors to compare a measure of our earnings before the effects of our indebtedness 

with that of other companies in the real estate industry; 

• 

• 

• 

• 

preferred  dividends,  to  allow  investors  to  compare  a  measure  of  our  performance  before  the  effects  of  our  capital  structure  and 
indebtedness with that of other companies in the real estate industry;  

income  taxes,  to  allow  investors  to  measure  our  performance  independent  of  income  taxes,  which  may  vary  significantly  from  other 
companies within our industry due to leverage and tax planning strategies, among other factors; 

depreciation and amortization, gains or losses on dispositions and impairment losses related to real estate, for similar reasons to those set 
forth in our discussion of FFO, Pro forma FFO and AFFO in the preceding section; and  

other items, including gains on dispositions of non-depreciable assets, as these are items that periodically affect our operations but that are 
not necessarily representative of our ability to service our debt obligations. 

While Adjusted EBITDA is a relevant measure of performance and is commonly used in leverage ratios, it does not represent net income as 
defined  by  GAAP,  and  should  not  be  considered  as  an  alternative  to  net  income  in  evaluating  our  performance.  Further,  our  definition  and 
computation of Adjusted EBITDA may not be comparable to similar measures reported by other companies.  

Adjusted Interest Expense, as calculated in our leverage ratios, is a non-GAAP measure that we believe is meaningful for investors and analysts 
as it presents our share of current recurring interest requirements associated with leverage. Our calculation of Adjusted Interest Expense is set forth 
in the table below. Adjusted Interest Expense represents our proportionate share of interest expense on non-recourse property debt encumbering 
apartment communities in the Real Estate portfolio and interest expense on our term loan and revolving credit facility borrowings. We exclude from 
our calculation of Adjusted Interest Expense: 

• 

• 

• 

debt prepayment penalties, which are items that, from time to time, affect our operating results, but are not representative of our scheduled 
interest obligations;  

the amortization of debt issue costs, as these amounts have been expended in previous periods and are not representative of our current or 
prospective debt service requirements; and 

the income we receive on our investment in the securitization trust that holds certain of our property debt, as this income is being generated 
indirectly from interest we pay with respect to property debt held by the trust. 

Preferred  Dividends  represents  the  preferred  dividends  paid  on  Aimco’s  preferred  stock  and  the  preferred  distributions  paid  on  the  Aimco 
Operating Partnership’s preferred OP Units, exclusive of preferred equity redemption related amounts. We add Preferred Dividends to Adjusted 
Interest Expense for a more complete picture of the interest and dividend requirements of our leverage, inclusive of perpetual preferred equity.

(1) In our calculation of leverage ratios for the three months ended December 31, 2017, we adjusted our calculation of Adjusted EBITDA to reflect the 

disposition of five apartment communities sold during the period as if they had closed on October 1, 2017, because the proceeds from these sales were used 
to reduce leverage as of December 31, 2017.

Liquidity  is  the  ability  to  meet  present  and  future  financial  obligations.  Our  primary  source  of  liquidity  is  cash  flow  from  our  operations. 
Additional sources are proceeds from sales of apartment communities, proceeds from refinancings of existing property debt, borrowings under new 
property  debt,  borrowings  under  our  Credit  Agreement,  as  defined  below,  including  our  revolving  credit  facility,  and  proceeds  from  equity 
offerings. 

Our  principal  uses  for  liquidity  include  normal  operating  activities,  payments  of  principal  and  interest  on  outstanding  property  debt,  capital 
expenditures, dividends paid to stockholders, distributions paid to noncontrolling interest partners and acquisitions of apartment communities. We 
use our cash and cash equivalents and our cash provided by operating activities to meet short-term liquidity needs. In the event that our cash and 
cash equivalents and cash provided by operating activities are not sufficient to cover our short-term liquidity needs, we have additional means, 
such as short-term borrowing availability and proceeds from apartment community sales and refinancings. We may use our revolving credit facility 
for  working  capital  and  other  short-term purposes, such as funding investments on an interim basis. We expect to meet our long-term  liquidity 
requirements, such as debt maturities, redevelopment spending and apartment community acquisitions, through long-term borrowings (primarily 
non-recourse), the issuance of equity securities (including OP Units), the sale of apartment communities and cash generated from operations. 

As of December 31, 2017, our primary sources of liquidity were as follows: 

•  $60.5 million in cash and cash equivalents;

•  $34.8 million of restricted cash, which consists primarily of escrows related to resident security deposits and reserves and escrows held by 

lenders for capital additions, property taxes and insurance; and 

•  $521.3 million of available capacity to borrow under our revolving credit facility (which is more fully described below), after consideration of 

outstanding borrowings of $67.2 million and $11.5 million of letters of credit backed by the facility. 

At December 31, 2017, we also held unencumbered apartment communities with an estimated fair market value of approximately $1.8 billion. Each 

of the amounts presented above exclude amounts attributable to partnerships served by our Asset Management business.  

Leverage and Capital Resources 

The  availability  of  credit  and  its  related  effect  on  the  overall  economy  may  affect  our  liquidity  and  future  financing  activities,  both  through 
changes in interest rates and access to financing. Currently, interest rates are low compared to historical levels and many lenders are active in the 
market. However, any adverse changes in the lending environment could negatively affect our  

 
 
 
  
  
 
 
 
 
39 

Table of Contents 

liquidity. We believe we have mitigated much of this exposure by reducing our short and intermediate term maturity risk through refinancing such 
loans with long-dated,  fixed-rate  property  debt.  However,  if  property  financing  options  become  unavailable  for  our  further  debt  needs,  we  may 
consider alternative sources of liquidity, such as reductions in capital spending or proceeds from apartment community dispositions. 

Two credit rating agencies rate our creditworthiness and both have rated our credit and outlook as BBB- (stable), an investment grade rating. 
Our investment grade rating would be useful in accessing capital through the sale of bonds in private or public transactions. However, our intention 
and historical practice has been to raise debt capital in the form of property-level, non-recourse, long-dated, fixed-rate, amortizing debt, the cost of 
which is generally less than that of recourse debt and the terms of which also provide for greater balance sheet safety. 

At  December  31,  2017,  approximately  86.7%  of  our  leverage  consisted  of  property-level,  non-recourse,  long-dated,  amortizing  debt. 
Approximately 97.7%  of  our  property-level debt is fixed-rate, which provides a hedge against increases in interest rates, capitalization rates and 
inflation. The weighted average maturity of our property-level debt was 7.2 years. 

For property debt encumbering the communities in our Real Estate portfolio, $173.7 million of our unpaid principal balances mature during 2018, 
of  which  $111.5  million  was  refinanced  in  January  2018  with  ten-year, fixed-rate,  non-recourse  property  debt.  On  average,  13.6%  of  our  unpaid 
principal balances will mature each year from 2019 through 2021. 

While our primary source of leverage is property-level, non-recourse, long-dated, fixed-rate, amortizing debt, we have a Senior Secured Credit 
Agreement with a syndicate of financial institutions, which we refer to as our Credit Agreement. Our Credit Agreement provides for $600.0 million of 
revolving loan commitments. As of  December  31,  2017, we had  $67.2 million  of  outstanding  borrowings  under  our  revolving  loan  commitments, 
representing 1.6% of our total leverage. The Credit Agreement provides us with an option to expand the aggregate loan commitments, subject to 
customary conditions, by up to $200.0 million. 

During 2017, we amended the Credit Agreement to add a $250.0 million term loan to fund partially our reacquisition of limited partner interests in 
the Palazzo joint venture. The term loan represents 6.1% of our total leverage as of December 31, 2017, matures on June 30, 2018, has a one-year 
extension option and bears interest at 30-day LIBOR plus 135 basis points.  

As  of  December  31,  2017,  our  outstanding  perpetual  preferred  equity  represented  approximately  5.5%  of  our  total  leverage.  Our  preferred 
securities are perpetual in nature; however, for illustrative purposes, we compute the weighted average maturity of our total leverage assuming a 40-
year maturity on our preferred securities. 

The combination of non-recourse property level debt, borrowings under our Credit Agreement and perpetual preferred equity that comprises our 
total leverage, reduces our refunding and re-pricing risk. The weighted average maturity for our total leverage described above was 8.5 years as of 
December 31, 2017.  

Under the Credit Agreement, we have agreed to maintain Fixed Charge Coverage ratio of 1.40x, as well as other covenants customary for similar 
revolving credit arrangements. For the year ended December 31, 2017, our Fixed Charge Coverage ratio was 2.01x, compared to ratio of 1.96x for the 
year ended December 31, 2016. We expect to remain in compliance with this covenant during the next 12 months.  

Changes in Cash and Cash Equivalents 

The following discussion relates to changes in consolidated cash and cash equivalents due to operating, investing and financing activities, 

which are presented in our consolidated statements of cash flows in Item 8 of this report. 

Operating Activities 

For the  year ended December 31, 2017, our net cash provided by operating activities was  $394.1 million. Our operating cash flow is affected 
primarily by rental rates, occupancy levels and operating expenses related to our portfolio of apartment communities. Cash provided by operating 
activities for the year ended December 31, 2017, increased by $16.4 million compared to 2016, due to improved operating results of our Same Store 
communities and increased contribution from redevelopment and lease-up communities, partially offset by a decrease in the net operating income 
associated with apartment communities we sold during 2016.  

40 

 
 
Table of Contents 

Investing Activities 

For the year ended December 31, 2017, net cash provided by investing activities of $14.7 million consisted primarily of $402.2 million in proceeds 

from the sale of apartment communities, partially offset by capital expenditures.  

For the years ended December 31, 2017, 2016 and 2015, we sold and acquired various apartment communities as further discussed in Note 3 to 

the consolidated financial statements in Item 8. 

Capital additions for our Real Estate segment totaled $338.0 million, $321.0 million and $340.3 million during the years ended December 31, 2017, 
2016  and  2015,  respectively.  We  generally  fund  capital  additions  with  cash  provided  by  operating  activities  and  cash  proceeds  from  sales  of 
apartment communities.  

We categorize capital spending for communities in our Real Estate portfolio broadly into six primary categories:  

• 

• 

• 

• 

• 

• 

capital replacements, which represent capital additions made to replace the portion of acquired apartment communities consumed during 
our period of ownership; 

capital improvements, which represent capital additions made to replace the portion of acquired apartment communities consumed prior to 
our period of ownership;  

capital  enhancements,  which  may  include  kitchen  and  bath  remodeling,  energy  conservation  projects  and  investments  in  longer-lived 
materials designed to reduce turnover and maintenance costs, all of which are generally lesser in scope than redevelopment additions and 
do not significantly disrupt property operations;  

redevelopment additions, which represent capital additions intended to enhance the value of the apartment community through the ability 
to generate higher average rental rates, and may include costs related to entitlement, which enhance the value of a community through 
increased density, and costs related to renovation of exteriors, common areas or apartment homes;  

development  additions,  which  represent  construction  and  related  capitalized  costs  associated  with  development  of  apartment 
communities; and  

casualty  capital  additions,  which  represent  construction  and  related  capitalized  costs  incurred  in  connection  with  the  restoration  of  an 
apartment community after a casualty event such as a severe snow storm, hurricane, tornado, flood or fire. 

We exclude from these measures the amounts of capital spending related to apartment communities sold or classified as held for sale at the end 
of the period, as well as amounts expended by consolidated partnerships served by our Asset Management business as such amounts generally do 
not affect the amount of cash flow we expect to receive from the operation and ultimate disposition of these communities. 

A summary of the capital spending for these categories, along with a reconciliation of the total for these categories to the capital expenditures 
reported in the accompanying consolidated statements of cash flows for the years ended December 31, 2017, 2016 and 2015, are presented below

(1) Redevelopments  provide  us  with  the  flexibility  to  align  the  timing  of  completed  apartment  homes  with  market  demand.  As  such,  expected  occupancy 

stabilization and expected NOI Stabilization dates may change as market conditions evolve. 

(2) This phase of redevelopment encompasses common areas, amenity improvements, residential homes on one floor and the creation of a new retail space. 

(3) In response to market conditions, during 2017, we decided to pause redevelopment activities pertaining to apartment homes and will reassess an appropriate 

time to resume such activity. Redevelopment of common areas, such as corridors, is ongoing and expected to be complete in early 2018.  

(4) This phase of the redevelopment encompasses common areas and security system upgrades. 

(5) In response to market conditions, during 2017, we decided to pause redevelopment activities and will reassess an appropriate time to resume redevelopment 

activity. 

Net investment represents the total actual or estimated investment, net of tax and other credits earned as a direct result of our redevelopment or 

development of the community. 

NOI  Stabilization  represents  the  period  in  which  we  expect  the  communities  to  achieve  stabilized  rents  and  operating  costs,  generally  five 

quarters after occupancy stabilization. 

During the year ended December 31, 2017, we invested $172.4 million primarily in our ongoing redevelopment and development projects. 

During the year ended December 31, 2017, we completed construction on the third tower of Park Towne Place in Center City, Philadelphia. As of 
December 31, 2017, the first three towers combined were 89% leased with approximately 40 homes remaining to be leased at the third redeveloped 
tower to reach occupancy stabilization. Based on these results, we decided to proceed with a $40 million redevelopment of the fourth and final 
tower. We have completed de-leasing and commenced construction on this tower, and lease-up is scheduled to commence in the spring of 2018.  

Also in Center City Philadelphia, during the year ended December 31, 2017, we completed redevelopment and the lease-up of the 534 apartment 
homes at The Sterling and substantially completed the reconfiguration of the second floor commercial space, upgrades to the third and fourth floor 
commercial space and upgrades to residential common areas.

We have planned and entitled a new $117.0 million, 226 apartment home community to be known as Parc Mosaic, located in Boulder, Colorado 
on the site of our Eastpointe community. As part of this plan, as of December 31, 2017, we completed the de-leasing of Eastpointe and commenced 
demolition and construction. The site is two miles from the new Google campus and is across the street from Ball Aerospace’s Technology Campus 
and Foothills Hospital. Building in Boulder is highly regulated and new supply is limited, notwithstanding higher enrollment at the University of 
Colorado and increased employment generally. 

Inclusive  of  the  redevelopment  and  development  projects  discussed  above,  during  the  year  ended  December  31,  2017  we  expanded  our 
redevelopment  and  development  pipeline  by  $228.9  million.  The  total  estimated  net  investment  for  these  redevelopment  and  development 
communities  is $714.6  million, with a projected weighted average net operating income yield on these investments of  6.1% assuming untrended 
rents. As of December 31, 2017, $513.1 million of this total has been funded. 

We expect our total redevelopment and development spending to range from $120 million to $200 million for the year ending December 31, 2018. 

Financing Activities 

For the year ended December 31, 2017, our net cash used in financing activities of $393.3 million was primarily attributed to our reacquisition of 
the limited partner interests in the Palazzo communities, dividends paid to common security holders, distributions paid to noncontrolling interests 
and  principal  payments  on  property  loans,  partially  offset  by  proceeds  from  the  term  loan,  net  borrowings  on  our  revolving  credit  facility,  and 
proceeds from non-recourse property debt. 

Net  borrowings  on  our  revolving  credit  facility  primarily  relate  to  the  timing  of  property  debt  financing  activities  and  apartment  community 
dispositions.  Proceeds  from  non-recourse  property  debt  borrowings  during  the  year  consisted  of  the  closing  of  seven fixed-rate,  non-recourse, 
amortizing, property loans totaling $308.8 million. On a weighted basis, the term of these loans averaged 8.2 years and their interest rates averaged 
3.48%, 121 basis points more than the corresponding 10-year Treasury rate at the time of pricing. 

We like the discipline of financing our investments in real estate through the use of fixed-rate, amortizing, non-recourse property debt, as the 
amortization gradually reduces our leverage and reduces our refunding risk, the fixed-rate provides a hedge against increases in interest rates, and 
the non-recourse feature avoids entity risk. 

Principal payments on property loans during the year totaled $409.2 million, consisting of $85.1 million of scheduled principal amortization and 

repayments of $324.1 million.

(1)  Includes  scheduled  principal  amortization  and  maturity  payments  related  to  our  non-recourse  property  debt  secured  by  communities  in  our  Real  Estate 

portfolio. 

(2)  Includes outstanding borrowings on our revolving credit facility assuming repayment at the contractual maturity date. Our revolving credit facility is subject 

to an annual commitment fee (0.25% of aggregate commitments), which is not included in the amounts above. 

(3)  Represents the term loan that matures on June 30, 2018 and has a one-year extension option. 
(4)  Includes  interest  related  to  both  fixed-rate  and  variable-rate  non-recourse  property  debt,  our  variable-rate  revolving  credit  facility  borrowings,  and  our 
variable-rate  term  loan.  Interest  related  to  variable-rate  debt  is  estimated  based  on  the  rate  effective  at  December  31,  2017.  Refer  to  Note  4  to  the 
consolidated financial statements in Item 8 for a description of average interest rates associated with our debt. 

(5)  These ground leases expire in years ranging from 2063 to 2087.
(6)  Represents estimated obligations pursuant to construction contracts related to our redevelopment, development and other capital spending. Refer to Note 5

to the consolidated financial statements in Item 8 for additional information regarding these obligations. 

In addition to the amounts presented in the table above, at December 31, 2017, we had  $125.0 million (liquidation value) of Aimco’s perpetual 
preferred stock outstanding with an annual dividend yield of 6.9% and $101.5 million (liquidation value) of redeemable preferred OP Units of the 
Aimco Operating Partnership outstanding with annual distribution yields ranging from 1.92% to 8.8%. The dividends and distributions that accrue 
on the perpetual preferred stock and redeemable preferred OP Units are cumulative and are paid quarterly. 

At December 31, 2017, communities owned by partnerships served by our Asset Management business were encumbered by $231.4 million of 
non-recourse property debt, $43.3 million of which matures in the next five years. The partnerships’ future obligation for interest related to this debt 
is $124.6 million, $52.3 million of which will be incurred over the next five years. The non-recourse property debt obligations of these partnerships 
have limited effect on the amount of fees and other payments we expect to receive. 

Additionally, we may enter into commitments to purchase goods and services in connection with the operations of our apartment communities. 

Those commitments generally have terms of one year or less and reflect expenditure levels comparable to our historical expenditures. 

Future Capital Needs 

In addition to the items set forth in “Contractual  Obligations” above, we expect to fund any future acquisitions, redevelopment, development 
and  other  capital  spending  principally  with  proceeds  from  apartment  community  sales,  short-term  borrowings,  debt  and  equity  financing  and 
operating cash flows. Our near-term business plan does not contemplate the issuance of equity.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk 

Our chief market risks are refunding risk, that is the availability of property debt or other cash sources to refund maturing property debt, and re-
pricing  risk,  that  is  the  possibility  of  increases  in  base  interest  rates  and  credit  risk  spreads.  We  use  predominantly  long-dated,  fixed-rate, 
amortizing,  non-recourse  property  debt  in  order  to  avoid  the  refunding  and  repricing  risks  of  short-term  borrowings.  We  use  short-term  debt 
financing  and  working  capital  primarily  to  fund  short-term  uses  and  generally  expect  to  refinance  such  borrowings  with  cash  from  operating 
activities, proceeds from apartment community sales, long-term debt or equity financings. We make limited use of derivative financial instruments 
and we do not use them for trading or other speculative purposes.  

Market Risk Associated with Loans Secured by Our Real Estate Portfolio 

As of December 31, 2017, on a consolidated basis, we had approximately $82.7 million of variable-rate property-level debt outstanding and $317.2 
million of variable-rate borrowings under our Credit Agreement, including a $250.0 million term loan that matures on June 30, 2018. We estimate that 
a change in 30-day LIBOR of 100 basis points with constant credit risk spreads would reduce or increase net income attributable to Aimco common 
stockholders and the Aimco Operating Partnership’s common unitholders by approximately $3.8 million on an annual basis. 

At December 31, 2017, our Real Estate segment had approximately $95.3 million in cash and cash equivalents and restricted cash, a portion of 

which bears interest at variable rates, which may offset somewhat a change in rates on our variable-rate debt discussed above.  

We estimate the fair value of debt instruments as described in Note 11 to the consolidated financial statements in Item 8. The estimated fair value 
of indebtedness associated with the Real Estate portfolio was approximately $3.9 billion at December 31, 2017, inclusive of a $55.1 million mark-to-
market liability. The mark-to-market liability decreased by $9.8 million as compared to the mark-to-market liability at December 31, 2016. 

If market rates for consolidated fixed-rate debt were higher by 100 basis points with constant credit risk spreads, the estimated fair value of debt 
discussed above would decrease from  $3.9 billion to  $3.8 billion. If market rates for consolidated debt discussed above were lower by 100 basis 
points with constant credit risk spreads, the estimated fair value of consolidated fixed-rate debt would increase from $3.9 billion in the aggregate to 
$4.0 billion. 

Market Risk Associated with Our Asset Management Business 

The carrying value of non-recourse property debt of the partnerships served by our Asset Management business of $227.1 million and $236.4 
million approximated its estimated fair value at December 31, 2017 and 2016, respectively. All of the non-recourse property debt of these partnership 
is fixed-rate debt. We do not believe this indebtedness represents a market risk for Aimco because increases or decreases in the fair value of the 
indebtedness are not expected to have a significant effect on the fees we expect to collect from these consolidated partnerships.

Item 9A. Controls and Procedures 

Aimco 

Disclosure Controls and Procedures 

Aimco’s management, with the participation of Aimco’s chief executive officer and chief financial officer, has evaluated the effectiveness of its 
disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act), as of the end of the period covered by 
this report. Based on such evaluation, Aimco’s chief executive officer and chief financial officer have concluded that, as of the end of such period, 
Aimco’s disclosure controls and procedures are effective.  

Management’s Report on Internal Control Over Financial Reporting  

Aimco’s  management  is  responsible  for  establishing  and  maintaining  adequate  internal  control  over  financial  reporting.  Internal  control  over 
financial reporting is defined in Rule 13a-15(f) and 15d-15(f) under the Exchange Act as a process designed by, or under the supervision of, our 
principal executive and principal financial officers and effected by our Board of Directors, management and other personnel to provide reasonable 
assurance  regarding  the  reliability  of  financial  reporting  and  the  preparation  of  financial  statements  for  external  purposes  in  accordance  with 
generally accepted accounting principles and includes those policies and procedures that:  

• 

• 

• 

pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of assets;

provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with 
generally accepted accounting principles, and that receipts and expenditures are being made only in accordance with authorizations of our 
management and directors; and  

provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of assets that could 
have a material effect on the financial statements. 

Because  of  its  inherent  limitations,  internal  control  over  financial  reporting  may  not  prevent  or  detect  misstatements.  Projections  of  any 
evaluation of effectiveness to future periods are subject to the risks that controls may become inadequate because of changes in conditions, or that 
the degree of compliance with the policies or procedures may deteriorate. 

Management assessed the effectiveness of Aimco’s internal control over financial reporting as of December 31, 2017. In making this assessment, 
management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control-
Integrated Framework (2013 Framework). 

Based on their assessment, management concluded that, as of December 31, 2017, Aimco’s internal control over financial reporting is effective. 

Aimco’s independent registered public accounting firm has issued an attestation report on Aimco’s internal control over financial reporting. 

Changes in Internal Control Over Financial Reporting 

There has been no change in Aimco’s internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange 
Act) during the fourth quarter of 2017 that has materially affected, or is reasonably likely to materially affect, Aimco’s internal control over financial 
reporting.

Definition and Limitations of Internal Control Over Financial Reporting 

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial 
reporting  and  the  preparation  of  financial  statements  for  external  purposes  in  accordance  with  generally  accepted  accounting  principles.  A 
company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in

company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the 
company’s assets that could have a material effect on the financial statements. 

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any 
evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that

Report of Independent Registered Public Accounting Firm 

The Board of Directors and Stockholders of 
Apartment Investment and Management Company 

Opinion on the Financial Statements 

We  have  audited  the  accompanying  consolidated  balance  sheets  of  Apartment  Investment  and  Management  Company  (the  Company)  as  of 
December 31, 2017 and 2016, the related consolidated statements of operations, comprehensive income, equity, and cash flows for each of the three 
years  in  the  period  ended  December  31,  2017,  and  the  related  notes  and  the  financial  statement  schedule  listed  in  the  accompanying  Index  to 
Financial  Statements  (collectively  referred  to  as  the  “consolidated  financial  statements”).  In  our  opinion,  the  consolidated  financial  statements 
present fairly, in all material respects, the financial position of the Company at December 31, 2017 and 2016, and the results of its operations and its 
cash flows for each of the three years in the period ended December 31, 2017, in conformity with U.S. generally accepted accounting principles. 

We  also  have  audited,  in  accordance  with  the  standards  of  the  Public  Company  Accounting  Oversight  Board  (United  States)  (PCAOB),  the 
Company's internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control-Integrated Framework 
issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission  (2013  framework)  and  our  report  dated  February 28,  2018 
expressed an unqualified opinion thereon. 

Adoption of New Accounting Standard 

As  discussed  in  Note  2  to  the  consolidated  financial  statements,  the  Company  changed  its  accounting  for  the  income  tax  consequences  of 

intercompany transfers of assets effective January 1, 2017. 

Basis for Opinion 

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company’s 
financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with 
respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange 
Commission and the PCAOB. 

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain 
reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included 
performing  procedures  to  assess  the  risks  of  material  misstatement  of  the  financial  statements,  whether  due  to  error  or  fraud,  and  performing 
procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in 
the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well 
as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion. 

We have served as the Company’s auditor since 1994.

The Partners of 
AIMCO Properties, L.P. 

Opinion on the Financial Statements 

Report of Independent Registered Public Accounting Firm 

We have audited the accompanying consolidated balance sheets of AIMCO Properties, L.P. (the “Partnership”)  as of  December  31,  2017 and 
2016, the related consolidated statements of operations, comprehensive income, partners' capital, and cash flows for each of the three years in the 
period  ended  December  31,  2017,  and  the  related  notes  and  the  financial  statement  schedule  listed  in  the  accompanying  Index  to  Financial 
Statements (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, 
in all material respects, the financial position of the Partnership at December 31, 2017 and 2016, and the results of its operations and its cash flows 
for each of the three years in the period ended December 31, 2017, in conformity with U.S. generally accepted accounting principles. 

We  also  have  audited,  in  accordance  with  the  standards  of  the  Public  Company  Accounting  Oversight  Board  (United  States)  (PCAOB),  the 
Partnership's  internal  control  over  financial  reporting  as  of  December  31,  2017,  based  on  criteria  established  in  Internal  Control-Integrated 
Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated February 28, 
2018 expressed an unqualified opinion thereon. 

Adoption of New Accounting Standard 

As discussed in Note 2 to the consolidated financial statements, the Partnership changed its accounting for the income tax consequences of 

intercompany transfers of assets effective January 1, 2017. 

Basis for Opinion 

These  financial  statements  are  the  responsibility  of  the  Partnership's  management.  Our  responsibility  is  to  express  an  opinion  on  the 
Partnership’s  financial  statements  based  on  our  audits.  We  are  a  public  accounting  firm  registered  with  the  PCAOB  and  are  required  to  be 
independent  with  respect  to  the  Partnership  in  accordance  with  the  U.S.  federal  securities  laws  and  the  applicable  rules  and  regulations  of  the 
Securities and Exchange Commission and the PCAOB. 

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain 
reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included 
performing  procedures  to  assess  the  risks  of  material  misstatement  of  the  financial  statements,  whether  due  to  error  or  fraud,  and  performing 
procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in 
the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well 
as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion. 

/s/ ERNST & YOUNG LLP  

We have served as the Partnership’s auditor since 1994.

APARTMENT INVESTMENT AND MANAGEMENT COMPANY 
AIMCO PROPERTIES, L.P. 
NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS 
December 31, 2017  

Apartment  Investment  and  Management  Company,  or  Aimco,  is  a  Maryland  corporation  incorporated  on  January  10,  1994.  Aimco  is  a  self-
administered and self-managed real estate investment trust, or REIT. AIMCO Properties, L.P., or the Aimco Operating Partnership, is a Delaware 
limited partnership formed on May 16, 1994, to conduct our business, which is focused on the ownership, management, redevelopment and limited 
development of quality apartment communities located in some of the largest markets in the United States. 

Aimco, through its wholly-owned subsidiaries, AIMCO-GP, Inc. and AIMCO-LP Trust, owns a majority of the ownership interests in the Aimco 
Operating Partnership. Aimco conducts all of its business and owns all of its assets through the Aimco Operating Partnership. Interests in the 
Aimco Operating Partnership that are held by limited partners other than Aimco are referred to as OP Units. OP Units include common partnership 
units, which we refer to as common OP Units, as well as partnership preferred units, which we refer to as preferred OP Units. As of December 31, 
2017, after eliminations for units held by consolidated subsidiaries, the Aimco Operating Partnership had 164,617,537  common  partnership  units 
outstanding. As of December 31, 2017, Aimco owned 157,189,447 of the common partnership units (95.5% of the common partnership units) of the 
Aimco Operating Partnership and Aimco had outstanding an equal number of shares of its Class A Common Stock, which we refer to as Common 
Stock. 

Except  as  the  context  otherwise  requires,  “we,”  “our”  and  “us”  refer  to  Aimco,  the  Aimco  Operating  Partnership  and  their  consolidated 

subsidiaries, collectively. 

As of December 31, 2017, we owned an equity interest in 136 apartment communities with 36,904 apartment homes in our Real Estate portfolio. 
Our Real Estate portfolio, which comprises our reportable segment, is diversified by both price point and geography and consists of market rate 
apartment communities in which we own a substantial interest. We consolidated 132 of these apartment communities with 36,762 apartment homes.  

As  of  December  31,  2017,  we  also  held  nominal  ownership  positions  in  partnerships  that  own  46  low-income  housing  tax  credit  apartment 
communities  with  6,898  apartment  homes.  We  provide  services  to  these  partnerships  and  receive  fees  and  other  payments  in  return.  Our 
relationship  with  these  partnerships  is  different  than  real  estate  ownership  and  is  better  described  as  an  asset  management  business,  or  Asset 
Management.  In  accordance  with  accounting  principles  generally  accepted  in  the  United  States  of  America,  or  GAAP,  we  are  required  to 
consolidate partnerships owning an aggregate of 39 apartment communities with 6,211 apartment homes. 

Note 2 — Basis of Presentation and Summary of Significant Accounting Policies 

Principles of Consolidation 

Aimco’s  accompanying  consolidated  financial  statements  include  the  accounts  of  Aimco,  the  Aimco  Operating  Partnership,  and  their 
consolidated  subsidiaries.  The  Aimco  Operating  Partnership’s  consolidated  financial  statements  include  the  accounts  of  the  Aimco  Operating 
Partnership and its consolidated subsidiaries. All significant intercompany balances have been eliminated in consolidation.  

Interests in the Aimco Operating Partnership that are held by limited partners other than Aimco are reflected in Aimco’s accompanying balance 
sheets as noncontrolling interests in Aimco Operating Partnership. Interests in partnerships consolidated into the Aimco Operating Partnership that 
are held by third parties are reflected in our accompanying balance sheets as noncontrolling interests in consolidated real estate partnerships. The 
assets of real estate partnerships consolidated by the Aimco Operating Partnership must first be used to settle the liabilities of such consolidated 
real estate partnerships. These consolidated real estate partnerships’ creditors do not have recourse to the general credit of the Aimco Operating 
Partnership.  

As used herein, and except where the context otherwise requires, “partnership” refers to a limited partnership or a limited liability company and 

“partner” refers to a partner in a limited partnership or a member of a limited liability company. 

Acquisition of Real Estate and Related Depreciation and Amortization 

We  generally  recognize  the  acquisition  of  apartment  communities  or  interests  in  partnerships  that  own  apartment  communities  at  cost.  The 

related transaction costs are generally included in the cost of the acquired apartment community. 

F-16 

 
 
 
Table of Contents 

We  allocate  the  cost  of  apartment  communities  acquired  based  on  the  relative  fair  value  of  the  assets  acquired  and  liabilities  assumed.  We 
determine  the  fair  value  of  tangible  assets,  such  as  land,  buildings,  furniture,  fixtures  and  equipment,  generally  using  valuation  techniques  that 
consider comparable market transactions, replacement costs and other available information. We determine the fair value of identified intangible 
assets  (or  liabilities),  which  typically  relate  to  in-place leases, using valuation techniques that consider the terms of the in-place leases, current 
market data for comparable leases and our experience in leasing similar communities. The intangible assets or liabilities related to in-place leases are 
comprised of: (a) the value of the above- and below-market leases in-place, measured over the period, including probable lease renewals for below-
market leases, that the leases are expected to remain in effect; (b) the estimated unamortized portion of avoided leasing commissions and other costs 
that ordinarily would be incurred to originate the in-place leases; and (c) the value associated with leased apartment homes during an estimated 
absorption period (estimates of rental revenue that would not have been earned had leased apartment homes been vacant at the time of acquisition 
assuming lease-up periods based on market demand and stabilized occupancy levels).  

Depreciation  for  all  tangible  assets  is  calculated  using  the  straight-line  method  over  their  estimated  useful  lives.  Acquired  buildings  and 
improvements  are  depreciated  over  a  useful  life based on the age, condition and other physical characteristics of the apartment  community. At 
December  31,  2017, the weighted average depreciable life of our buildings and improvements was approximately  28 years. Furniture, fixtures and 
equipment associated with apartment communities are depreciated over five years.  

The above- and below-market lease intangibles are amortized to rental revenue over the expected remaining terms of the associated leases, which 
include reasonably assured renewal periods. Other intangible assets related to in-place leases are amortized to depreciation and amortization over 
the expected remaining terms of the associated leases.  

At December 31, 2017 and 2016, deferred income in our consolidated balance sheets included below-market lease amounts totaling $9.1 million 
and $10.4 million, respectively, which are net of accumulated amortization of $34.4 million and $33.1 million, respectively. During the years ended 
December 31, 2017, 2016 and 2015, we included amortization of below-market leases of $1.3 million, $1.7 million and $1.7 million, respectively, in rental 
and other property revenues in our consolidated statements of operations. 

At December 31, 2017, our below-market leases had a weighted average amortization period of 6.2 years and estimated aggregate amortization for 

each of the five succeeding years as follows (in thousands):

Capital Additions and Related Depreciation  

We  capitalize  costs,  including  certain  indirect  costs,  incurred  in  connection  with  our  capital  additions  activities,  including  redevelopments, 
developments,  other  tangible  apartment  community  improvements  and  replacements  of  existing  apartment  community  components.  Included  in 
these  capitalized  costs  are  payroll  costs  associated  with  time  spent  by  site  employees  in  connection  with  capital  additions  activities  at  the 
apartment community level. We characterize as “indirect costs” an allocation of certain department costs, including payroll, at the area operations 
and corporate levels that clearly relate to capital additions activities. We also capitalize interest, property taxes and insurance during periods in 
which redevelopments, developments and construction projects are in progress. We begin capitalization of costs, including certain indirect costs, 
incurred in connection with our capital addition activities, upon commencement of activities necessary to get apartment communities ready for their 
intended use. These activities include when apartment communities or apartment homes are undergoing physical construction, as well as when 
apartment homes are held vacant in advance of planned construction, provided that other activities such as permitting, planning and design are in 
progress. We cease the capitalization of costs when the apartment communities are substantially complete and ready for their intended use, which 
is  typically  when  construction  has  been  completed  and  apartment  homes  are  available  for  occupancy.  Costs,  including  ordinary  repairs, 
maintenance and resident turnover costs, are charged to property operating expense as incurred.  

We depreciate capitalized costs using the straight-line method over the estimated useful life of the related improvement, which is generally 5, 15 
or  30  years.  All  capitalized  site  payroll  costs  and  indirect  costs  are  allocated  to  capital  additions  proportionately,  based  on  direct  costs  and 
depreciated over the estimated useful lives of such capital additions.  

F-17 

 
 
  
  
 
Table of Contents 

Certain  homogeneous  items  that  are  purchased  in  bulk  on  a  recurring  basis,  such  as  carpeting  and  appliances,  are  depreciated  using  group 
methods that reflect the average estimated useful life of the items in each group. Except in the case of apartment community casualties, where the 
net book value of the lost asset is written off in the determination of casualty gains or losses, we generally do not recognize any loss in connection 
with  the  replacement  of  an  existing  apartment  community  component  because  normal  replacements  are  considered  in  determining  the  estimated 
useful lives used in connection with our composite and group depreciation methods.  

For the years ended December 31, 2017, 2016 and 2015, we capitalized to buildings and improvements $7.6 million, $9.6 million and $11.7 million 

of interest costs, respectively, and $36.0 million, $32.9 million and $28.2 million of other direct and indirect costs, respectively.  

Impairment of Long-Lived Assets 

Real  estate  and  other  long-lived  assets  to  be  held  and  used  are  stated  at  cost,  less  accumulated  depreciation  and  amortization,  unless  the 
carrying amount of the asset is not recoverable. If events or circumstances indicate that the carrying amount of an apartment community may not be 
recoverable, we make an assessment of its recoverability by comparing the carrying amount to our estimate of the undiscounted future cash flows, 
excluding interest charges, of the apartment community. If the carrying amount exceeds the aggregate undiscounted future cash flows, we recognize 
an impairment loss to the extent the carrying amount exceeds the estimated fair value of the apartment community.  

Cash Equivalents 

We classify highly liquid investments with an original maturity of three months or less as cash equivalents. We maintain cash equivalents in 
financial institutions in excess of insured limits. We have not experienced any losses in these accounts in the past and believe that we are not 
exposed to significant credit risk because our accounts are deposited with major financial institutions. 

Restricted Cash 

Restricted  cash  includes  capital  replacement  reserves,  completion  repair  reserves,  bond  sinking  fund  amounts,  tax  and  insurance  escrow 

accounts held by lenders and resident security deposits. 

Other Assets 

At December 31, 2017 and 2016, other assets was comprised of the following amounts (dollars in thousands): 

Investments in securitization trust that holds Aimco property debt 

Accumulated unrecognized deferred tax expense from intercompany transfers

As discussed under the Accounting Pronouncements Adopted in the Current Year heading, on January 1, 2017, we recognized a cumulative 
effect  adjustment  to  retained  earnings  and  partners’  capital,  which  reduced  to  zero  the  accumulated  unrecognized  deferred  tax  expense  from 
intercompany transfers. 

The  table  above  excludes  other  assets  of  partnerships  served  by  our  Asset  Management  business,  which  are  presented  separately  on  our 

consolidated balance sheet. 

Investments in Securitization Trust that holds Aimco Property Debt 

We hold investments in a securitization trust that primarily holds certain of our property debt. These investments were initially recognized at 
their purchase price and the discount to the face value is being accreted into interest income over the expected term of the securities. We have 
designated these investments as available for sale securities and we measure these investments at fair  

F-18 

 
 
  
  
  
  
  
  
  
  
  
  
Table of Contents 

value  with  changes  in  their  fair  value,  other  than  the  changes  attributed  to  the  accretion  described  above,  recognized  as  an  adjustment  of 
accumulated other comprehensive income or loss within equity and partners’ capital. Refer to Note 11 for further information regarding these debt 
securities. 

Intangible Assets 

At December 31, 2017 and 2016, other assets included goodwill associated with our reportable segment of $37.8 million. We perform an annual 
impairment test of goodwill by evaluating qualitative factors to determine the likelihood that goodwill may be impaired. We primarily consider the 
fair value of our real estate portfolio and the fair value of our debt relative to their carrying values. As a result of the qualitative analysis, we do not 
believe our goodwill is impaired as of the date of our annual test. 

During the years ended December 31, 2016 and 2015, we allocated $4.5 million and $1.2 million, respectively, of goodwill related to our reportable 
segments to the carrying amounts of the apartment communities sold or classified as held for sale. The amounts of goodwill allocated to these 
apartment communities were based on the relative fair values of the apartment communities sold or classified as held for sale. As further discussed 
under the Accounting Pronouncements Adopted in the Current Year heading, commencing in 2017 we no longer allocate goodwill to the carrying 
amounts of apartment communities sold or classified as held for sale that do not meet the definition of a business. 

Capitalized Software Costs 

Purchased  software  and  other  costs  related  to  software  purchased  or  developed  for  internal  use  are  capitalized  during  the  application 
development stage and are amortized using the straight-line method over the estimated useful life of the software, generally three to five years. For 
the years ended December 31, 2017, 2016 and 2015, we capitalized software purchase and development costs totaling $2.0 million, $3.4 million and 
$3.6  million,  respectively.  At  December  31,  2017  and  2016,  other  assets  included  $9.1  million  and  $12.6  million  of  net  capitalized  software, 
respectively.  During  the  years  ended  December  31,  2017,  2016 and  2015,  we  recognized  amortization  of  capitalized  software  of  $5.5 million,  $7.2 
million and $6.9 million, respectively, which is included in depreciation and amortization in our consolidated statements of operations. 

Investments in Unconsolidated Real Estate Partnerships 

We  own  general  and  limited  partner  interests  in  partnerships  that  either  directly,  or  through  interests  in  other  real  estate  partnerships,  own 
apartment  communities.  We  generally  account  for  investments  in  real  estate  partnerships  that  we  do  not  consolidate  under  the  equity  method. 
Under the equity method, we recognize our share of the earnings or losses of the entity for the periods presented, inclusive of our share of any 
impairments and disposition gains recognized by and related to such entities, and we present such amounts within other, net in our consolidated 
statements of operations.  

The excess of the cost of the acquired partnership interests over the historical carrying amount of partners’ equity or deficit is generally ascribed 
to the fair values of land and buildings owned by the partnerships. We amortize the excess cost related to the buildings over the related estimated 
useful lives. Such amortization is recorded as an adjustment of the amounts of earnings or losses we recognize from such unconsolidated real estate 
partnerships.  

Deferred Costs  

We defer lender fees and other direct costs incurred in obtaining new financing and amortize the amounts over the terms of the related loan 
agreements. Amortization of these costs is included in interest expense. Debt issue costs associated with our revolving credit facility are included in 
other assets on our consolidated balance sheets. Debt issue costs associated with non-recourse property debt and our term loan are presented as a 
direct deduction from the related liabilities on our consolidated balance sheets.  

We defer leasing commissions and other direct costs incurred in connection with successful leasing efforts and amortize the costs over the 

terms of the related leases. Amortization of these costs is included in depreciation and amortization.  

Noncontrolling Interests in Consolidated Real Estate Partnerships 

We  report  the  unaffiliated  partners’  interests  in  the  net  assets  of  our  consolidated  real  estate  partnerships  as  noncontrolling  interests  in 
consolidated  real  estate  partnerships  within  consolidated  equity  and  partners’  capital.  Noncontrolling  interests  in  consolidated  real  estate 
partnerships consist primarily of equity interests held by limited partners in consolidated real estate partnerships that have finite lives. We generally 
attribute to noncontrolling interests their share of income or loss of consolidated partnerships based on their proportionate interest in the results of 
operations of the partnerships, including their share of losses even if such attribution results in a deficit noncontrolling interest balance within our 
equity and partners’ capital accounts. 

F-19 

 
 
Table of Contents 

The  terms  of  the  related  partnership  agreements  generally  require  the  partnerships  to  be  liquidated  following  the  sale  of  the  underlying  real 
estate. As the general partner in these partnerships, we ordinarily control the execution of real estate sales and other events that could lead to the 
liquidation, redemption or other settlement of noncontrolling interests. 

Changes in our ownership interest in consolidated real estate partnerships generally consist of our purchase of an additional interest in or the 
sale of our entire interest in a consolidated real estate partnership. The effect on our equity and partners’ capital  of  our  purchase  of  additional 
interests in consolidated real estate partnerships during the years ended December 31, 2017, 2016 and 2015, is shown in our consolidated statements 
of equity and partners’ capital. The effect on our equity and partners’ capital of sales of consolidated real estate or sales of our entire interest in 
consolidated real estate partnerships is reflected in our consolidated financial statements as gains on disposition of real estate and accordingly the 
effect on our equity and partners’ capital is reflected within the amount of net income allocated to us and to noncontrolling interests. Upon our 
deconsolidation of a real estate partnership following the sale of our partnership interests or liquidation of the partnership following sale of the 
related  apartment  community,  we  derecognize  any  remaining  noncontrolling  interest  of  the  associated  partnership  previously  recorded  in  our 
consolidated balance sheets. 

Noncontrolling Interests in Aimco Operating Partnership 

Noncontrolling interests in Aimco Operating Partnership consist of common OP Units and preferred OP Units. Holders of preferred OP Units 
participate in the Aimco Operating Partnership’s income or loss only to the extent of their preferred distributions. Within Aimco’s consolidated 
financial statements, after provision for Preferred OP Unit distributions, the Aimco Operating Partnership’s income or loss is allocated to the holders 
of common partnership units based on the weighted average number of common partnership units (including those held by Aimco) outstanding 
during the period. During the years ended December 31, 2017, 2016 and 2015, the holders of common OP Units had a weighted average ownership 
interest in the Aimco Operating Partnership of 4.5%, 4.7% and 4.7%, respectively. See Note 7 for further information regarding the items comprising 
noncontrolling interests in the Aimco Operating Partnership. 

Revenue Recognition 

Our apartment communities have operating leases with apartment residents with terms averaging 12 months. We recognize rental revenue related 
to these leases, net of any concessions, on a straight-line basis over the term of the lease. We recognize revenues from asset management and other 
services when the related fees are earned and realized or realizable. 

Asset Management Business 

We are the general partner in certain low-income housing tax credit partnerships, which are structured to provide for the pass-through of tax 
credits and deductions to their partners. The tax credits are generally realized ratably over the first ten years of the tax credit arrangement and are 
subject to the partnership’s compliance with applicable laws and regulations for a period of 15 years. We hold nominal ownership positions in these 
partnerships, generally less than one percent. At inception, each investor agreed to fund capital contributions to the partnerships and we received a 
syndication  fee  from  the  partnerships  upon  the  investors’  admission  to  the  partnership.  In  our  role,  we  provide  asset  management  and  other 
services  to  these  partnerships  and  we  receive  fees  and  other  payments  in  return.  To  the  extent  amounts  due  to  us  are  not  paid  currently,  the 
balances accrue and are satisfied from the partnerships’ future operating or liquidating cash flow. 

Capital contributions received by the partnerships from tax credit investors represent, in substance, consideration that we receive in exchange 
for our obligation to deliver tax credits and other tax benefits to the investors. We record these contributions as deferred income in our consolidated 
balance sheets upon receipt, and we recognize these amounts as revenue in our consolidated statements of operations when our obligation to the 
investors is relieved upon delivery of the tax benefits. 

We consolidate the low-income housing tax credit partnerships in which we are the sole general partner, as further discussed in Note 13. When 
the contractual arrangements obligate us to deliver tax benefits to the investors, and entitle us through fee arrangements to receive substantially all 
available cash flow from the partnerships, we recognize the income or loss generated by the underlying real estate based on our economic interest 
in the partnerships’ current period results, which is approximately 100% and represents the allocation of cash available for distribution we would 
receive from a hypothetical liquidation at the book value of the partnership’s net assets. Our economic interest in these partnerships will be 100% 
until the limited partners become entitled to an allocation of distributable cash (generally upon sale of the underlying real estate). Our economic 
interest generally differs from our legal interest. 

Insurance 

We  believe  our  insurance  coverages  insure  our  apartment  communities  adequately  against  the  risk  of  loss  attributable  to  fire,  earthquake, 

hurricane, tornado, flood and other perils. In addition, we have third-party insurance coverage (after self-insured  

F-20 

 
 
Table of Contents 

retentions) that defray the costs of large workers’ compensation, health and general liability exposures. We accrue losses based upon our estimates 
of the aggregate liability for uninsured losses incurred using certain actuarial assumptions followed in the insurance industry and based on our 
experience.  

Share-Based Compensation 

We  issue  various  forms  of  share-based  compensation,  including  stock  options  and  restricted  stock  awards  with  service  conditions  and/or 
market conditions. We recognize share-based employee compensation based on the fair value on the grant date and recognize compensation cost 
over the awards’  requisite  service  periods.  We  reduce  compensation  cost  related  to  forfeited  awards  in  the  period  of  forfeiture.  See  Note 8  for 
further discussion of our share-based compensation. 

Income Taxes 

Aimco has elected to be taxed as a REIT under the Internal Revenue Code commencing with its taxable year ended December 31, 1994, and it 
intends to continue to operate in such a manner. Aimco’s current and continuing qualification as a REIT depends on its ability to meet the various 
requirements imposed by the Internal Revenue Code, which are related to organizational structure, distribution levels, diversity of stock ownership 
and certain restrictions with regard to owned assets and categories of income. If Aimco qualifies for taxation as a REIT, it will generally not be 
subject to United States federal corporate income tax on its taxable income that is currently distributed to stockholders. This treatment substantially 
eliminates the “double taxation” (at the corporate and stockholder levels) that generally results from an investment in a corporation.  

Even  if  Aimco  qualifies  as  a  REIT,  it  may  be  subject  to  United  States  federal  income  and  excise  taxes  in  various  situations,  such  as  on  our 
undistributed income. Aimco also will be required to pay a  100% tax on any net income on non-arm’s length transactions between it and a TRS 
(described below) and on any net income from sales of apartment communities that were held for sale in the ordinary course. The state and local tax 
laws may not conform to the United States federal income tax treatment, and Aimco may be subject to state or local taxation in various state or local 
jurisdictions, including those in which we transact business. Any taxes imposed on us reduce our operating cash flow and net income.  

Certain  of  our  operations  or  a  portion  thereof,  including  property  management  and  risk  management,  are  conducted  through  taxable  REIT 
subsidiaries,  which  are  subsidiaries  of  the  Aimco  Operating  Partnership,  and  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 and activities to our residents and investment partners that cannot be offered directly by a REIT. We also use 
TRS entities to hold investments in certain apartment communities. 

For our TRS entities, deferred income taxes result from temporary differences between the carrying amounts of assets and liabilities for financial 
reporting purposes and the amounts used for United States federal income tax purposes, and are measured using the enacted tax rates and laws that 
are expected to be in effect when the differences reverse. We reduce deferred tax assets by recording a valuation allowance when we determine, 
based  on  available  evidence,  that  it  is  more  likely  than  not  that  the  assets  will  not  be  realized.  As  further  discussed  under  the  Accounting 
Pronouncements Adopted in the Current Year heading within this note, commencing in 2017, we recognize the tax consequences associated with 
intercompany  transfers  between  the  Aimco  Operating  Partnership  and  TRS  entities  when  such  transactions  occur.  Refer  to  Note  9  for  further 
information about our income taxes. 

Comprehensive Income or Loss 

As discussed under the preceding Investments in Securitization Trust that holds Aimco Property Debt heading, we have investments that are 
measured at fair value with unrealized gains or losses recognized as an adjustment of accumulated other comprehensive loss within equity and 
partners’  capital.  Additionally,  as  discussed  in  Note  11,  we  recognize  changes  in  the  fair  value  of  our  cash  flow  hedges  as  an  adjustment  of 
accumulated other comprehensive loss within equity and partners’ capital. The amounts of consolidated comprehensive income for the years ended 
December  31,  2017,  2016  and  2015,  along  with  the  corresponding  amounts  of  such  comprehensive  income  attributable  to  Aimco,  the  Aimco 
Operating Partnership and to noncontrolling interests, are presented within the accompanying consolidated statements of comprehensive income. 

Earnings per Share and Unit 

Aimco and the Aimco Operating Partnership calculate earnings (loss) per share and unit based on the weighted average number of shares of 
Common Stock or common partnership units, participating securities, common stock or common unit equivalents and dilutive convertible securities 
outstanding during the period. The Aimco Operating Partnership considers both common partnership units and equivalents, which have identical 
rights to distributions and undistributed earnings, to be common units for purposes of the earnings per unit computations. See Note 10 for further 
information regarding earnings per share and unit computations.

Use of Estimates 

The preparation of our consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions 
that  affect  the  reported  amounts  included  in  the  financial  statements  and  accompanying  notes  thereto.  Actual  results  could  differ  from  those 
estimates. 

Reclassifications 

Certain items included in the 2016 and 2015 financial statements have been reclassified to conform to the current presentation. 

Accounting Pronouncements Adopted in the Current Year 

During 2017, we elected to adopt early the new accounting standard that revised the GAAP definition of a business. Under the new standard 
we expect apartment communities will no longer be considered businesses; therefore, transaction costs incurred related to the acquisition of real 
estate operations will be capitalized as a cost of the acquisition. Additionally, we will no longer allocate goodwill to sales of apartment communities 
for purposes of calculating gain or loss upon sale. We have applied the new standard prospectively to transactions occurring after adoption, which 
did not have a significant effect on our financial condition or results of operations. 

Effective  January  1,  2017,  we  adopted  a  new  standard  issued  by  the  Financial  Accounting  Standards  Board,  or  FASB,  that  simplifies  the 
accounting for the income tax consequences of intercompany transfers of assets. Previously, the recognition within the statement of operations of 
income  tax  expense  or  benefit  resulting  from  an  intercompany  transfer  of  assets  did  not  occur  until  the  assets  affect  GAAP  income  or  loss,  for 
example, through depreciation, impairment or upon the sale of the asset to a third-party. Under the new standard, we are required to recognize the 
income  tax  expense  or  benefit  from  an  intercompany  transfer  of  assets  when  the  transfer  occurs.  We  have  applied  this  change  on  a  modified 
retrospective basis and recognized a cumulative effect adjustment to retained earnings and partners’ capital of $65.7 million as of January 1, 2017, 
representing accumulated unrecognized tax expense from intercompany transfers between the Aimco Operating Partnership and TRS entities. Such 
amounts were included in other assets within our consolidated balance sheets at December 31, 2016. 

Also effective January 1, 2017, we adopted guidance that simplifies the accounting for share-based compensation. Under prior practice, tax 
benefits in excess of those associated with compensation cost recognized in accordance with GAAP, or windfalls, were recorded in equity and tax 
deficiencies were recorded in equity until previous windfalls had been recovered and then recognized in earnings. Under the new guidance, all of 
the tax effects related to share-based compensation are recognized through earnings. This guidance is applied to all windfalls and tax deficiencies 
resulting  from  settlements  occurring  after  January  1,  2017.  The  new  guidance  also  requires  windfalls  to  be  recorded  in  the  period  the  related 
transaction  triggering  tax  consequences  occurs,  such  as  an  exercise  of  stock  options  or  vesting  of  restricted  shares.  This  change  in  timing  of 
recognition has been applied on a modified retrospective basis. We did not record a cumulative effect adjustment to opening retained earnings on 
the date of adoption as there were no accumulated windfalls recorded in equity. Compared to prior periods, we may experience incremental volatility 
in income tax benefit or expense resulting from the recognition in earnings of windfall benefits or deficiencies upon the exercise of stock options and 
vesting of restricted shares. 

Recent Accounting Pronouncements 

The FASB has issued new standards that affect accounting for revenue from contracts with customers and are effective for us on January 1, 
2018. The new revenue standards establish a single comprehensive model for entities to use in accounting for revenue arising from contracts with 
customers and supersede most current GAAP applicable to revenue recognition. The core principle of the new guidance is that revenue should 
only be recognized when an entity has transferred control of goods or services to a customer and for an amount reflecting the consideration to 
which the entity expects to be entitled for such exchange. We have completed our analysis of the effect this guidance will have on our consolidated 
financial statements and have determined we will not recognize a cumulative effect adjustment upon adoption. We do not anticipate changes to the 
timing or amount of revenue we recognize on an ongoing basis as substantially all of our revenue is earned from leases and is subject to the current 
lease standard until the adoption of the new lease standard, which is discussed below.  

The FASB has also issued a new standard on lease accounting, which is effective for us on January 1, 2019. Under the new lease standard, 
lessor accounting will be largely unchanged, but lessees will be required to recognize a right of use asset and a lease liability for virtually all leases, 
with such leases classified as either operating or finance. The new standard must be adopted using a modified retrospective method, which requires 
application of the new guidance at the beginning of the earliest comparative period presented and provides for certain practical expedients, which 
we anticipate electing. We do not anticipate significant changes in the timing of income from our leases with residents. However, in circumstances 
where we are a lessee, in primarily a limited population of ground leases and leases for corporate office space, we will be required to recognize right 
of use assets and related lease liabilities on our consolidated balance sheets. We do not anticipate the adoption of this standard will have a material  

F-22 

 
 
Table of Contents 

effect on our financial condition or results of operations. We are in the process of determining the amount of the right of use assets and related 
lease liabilities that will be recognized upon adoption.  

During 2016, the FASB also issued an Accounting Standards Update that is intended to reduce diversity in the classification and presentation 
of changes in restricted cash in the statement of cash flows and is effective for us on January 1, 2018. The new standard requires that the statement 
of cash flows describe the changes in the combined balances of cash and cash equivalents and restricted cash during the period. The guidance is 
required to be applied retrospectively to each period presented in the financial statements. We currently present transfers between restricted and 
unrestricted  cash  accounts  as  operating,  investing  and  financing  activities  depending  upon  the  required  or  intended  purpose  for  the  restricted 
funds, and cash receipts and payments directly with third parties to or from restricted cash accounts are presented on the statement of cash flows 
as a net change in restricted cash and classified similarly to transfers between restricted and unrestricted cash. We expect that the primary change 
to our statement of cash flows will be the presentation of activity in the restricted cash accounts combined with similar activity in unrestricted 
accounts. 

Note 3 — Significant Transactions 

Reacquisition of Limited Partner Interest in Palazzo Joint Venture 

During the year ended December 31, 2017, we reacquired for $451.5 million, the 47% noncontrolling limited partner interest in the Palazzo joint 
venture, which owns three communities with a total of 1,382 apartment homes located in Los Angeles, California. We assumed $140.5 million of the 
noncontrolling interest partner’s share of existing non-recourse property-level debt and paid $311.0 million in cash consideration, which was funded 
by  short  term  borrowings.  We  now  own  all  of  the  interests  in  the  Palazzo  joint  venture  and  its  underlying  apartment  communities.  Prior  to  the 
transaction, we consolidated into our financial statements the joint venture and underlying apartment communities, therefore this transaction has 
been accounted for as an equity transaction. In accordance with GAAP, we recognized the $155.6  million of consideration paid in excess of the 
noncontrolling interest balance as a reduction of additional paid-in capital within Aimco’s equity and the Aimco Operating Partnership’s partners’ 
capital.  

Acquisitions of Apartment Communities  

During the year ended December 31, 2016, we purchased a 463-apartment community in Redwood City, California that was in the final stages of 
construction at the time of acquisition. At closing, we paid $303.0 million in cash and issued $17.0 million of 6.0% Class Ten preferred OP Units to 
the  seller.  The  purchase  price,  plus $1.8  million of capitalized transaction costs, was allocated as follows: $26.9  million to land; $292.7  million to 
buildings and improvements (including construction in progress); and $2.2 million to furniture and fixtures.  

In  February  2018,  we  purchased  a 748-apartment  home  community  in  Fairfax  County,  Virginia  for  $160.0  million.  Based  on  the  timing  of  this 

acquisition, we have not completed our purchase price allocation.

The apartment communities sold from our Real Estate portfolio during 2017, 2016 and 2015 were predominantly located outside of our primary 
markets  or  in  lower-rated  locations  within  our  primary  markets  and  had  average  revenues  per  apartment  home  significantly  below  those  of  our 
retained portfolio.  

In January 2018, we agreed to sell our interests in the entities owning the La Jolla Cove property in settlement of legal actions filed in 2014 by a 

group of disappointed buyers who had hoped to acquire the property. As a result of the settlement, we recognized

in our 2017 results of operations a gross impairment loss of $35.8 million, $25.6 million of which relates to the establishment of a deferred tax liability 
assumed in connection with our acquisition of the business entities. Upon closing of the transaction, the tax liability will be assumed by the buyer, 
resulting in no economic loss to Aimco. 

In addition to the apartment communities we sold during the periods presented, from time to time we may be marketing for sale certain apartment 
communities  that  are  inconsistent  with  our  long-term  investment  strategy.  At  the  end  of  each  reporting  period,  we  evaluate  whether  such 
communities meet the criteria to be classified as held for sale. As of December 31, 2017, we had three apartment communities with 513 apartment 
homes in our Real Estate portfolio that were classified as held for sale. In January 2018, we sold these apartment homes for a gain on disposition of 
$51.0  million,  net  of  tax,  and  gross  proceeds  of  $71.9 million  resulting  in  $64.6  million  of  net  proceeds  to  Aimco.  Proceeds  from  the  sales  were 
primarily used to repay outstanding borrowings under our Credit Agreement. 

Napico Disposition 

In 2012, we sold the Napico business. The transaction was primarily seller-financed, and the associated notes were scheduled to be repaid from 
the operation and liquidation of the Napico business and were collateralized by the buyer’s interests in the portfolio. During 2016, the buyer paid in 
full the seller-financed notes as well as an agreed upon final payment representing future contingent consideration that may have been due under 
the terms of the sale. As a result, we derecognized the net assets and liabilities of the Napico business with the exception of the amounts related to 
one community in which we had continuing involvement in the form of a legal interest in the community and a guarantee related to property-level 
debt. We recognized a gain of $5.2 million in other, net on our consolidated statement of operations for the year ended December 31, 2016. We also 
wrote off a deficit balance in noncontrolling interests in consolidated real estate partnerships associated with the Napico business of $8.1 million, 
which is recorded in net income attributable to noncontrolling interests in consolidated real estate partnerships for the  year ended December 31, 
2016.  

In 2017, the owner refinanced the mortgage related to the final community, resulting in the release of our remaining guarantee, which allowed us 
to transfer the nominal general partner interest in the community to the buyer. In connection with the transfer, we reduced other assets and accrued 
liabilities and other by $34.5 million and $38.4 million, respectively, and recognized a gain of $7.1 million, net of tax, in other, net in our consolidated 
financial statements for the year ended December 31, 2017.  

Note 4 — Non-Recourse Property Debt and Credit Agreement 

Non-Recourse Property Debt (Real Estate Portfolio) 

We finance apartment communities in our Real Estate portfolio primarily using property-level, non-recourse, long-dated,  fixed-rate, amortizing 
debt.  The  following  table  summarizes  non-recourse  property  debt  related  to  assets  classified  as  held  for  use  at  December 31, 2017  and 2016  (in

Fixed-rate property debt matures at various dates through January 2055, and has interest rates that range from 2.73% to 8.05%, with a weighted 
average interest rate of 4.64%. Principal and interest on fixed-rate debt are generally payable monthly or in monthly interest-only payments with 
balloon payments due at maturity. At December 31, 2017, each of the fixed-rate loans payable related to apartment communities classified as held for 
use were secured by one of 98 apartment communities that had an aggregate gross book value of $6.3 billion.  

Variable-rate property debt matures at various dates through July 2033, and had interest rates that ranged from 1.00% to 3.06%, as of December 
31, 2017, with a weighted average interest rate of 2.70% at December 31, 2017. Principal and interest on variable-rate debt are generally payable in 
semi-annual  installments  with  balloon  payments  due  at  maturity.  As  of December  31,  2017, our variable-rate  property  debt  related  to  apartment 
communities classified as held for use were each secured by seven apartment communities that had an aggregate gross book value of $204.2 million. 

These  non-recourse  property  debt  instruments  contain  covenants  common  to  the  type  of  borrowing,  and  at December  31,  2017,  we  were  in 

compliance with all such covenants.

We have a senior secured credit agreement with a syndicate of financial institutions, which we refer to as the Credit Agreement. Our Credit 
Agreement provides for $600.0 million of revolving loan commitments. Borrowings against the revolving loan commitments bear interest at a rate set 
forth on a pricing grid, which rate varies based on our credit rating as assigned by specified rating agencies (LIBOR plus 1.20%, or, at our option, a 
base rate plus 0.20% at December 31, 2017). The Credit Agreement matures on January 22, 2022. The Credit Agreement provides that we may make 
distributions to our investors during any four consecutive quarters in an aggregate amount that does not exceed the greater of 95% of our Funds 
From Operations for such period, subject to certain non-cash adjustments, or such amount as may be necessary to maintain Aimco’s REIT status. 

During 2017, we amended the Credit Agreement to add a $250.0 million term loan, which we used to fund a portion of the reacquisition of our 
limited partner’s interest in the Palazzo joint venture. The term loan matures on June 30, 2018, includes a one-year extension option, subject to the 
satisfaction of customary conditions, and bears interest at 30-day LIBOR plus 1.35%. We paid lender and other fees of $1.0 million in connection 
with the term loan, which have been deferred and are amortized as additional interest using the effective interest method. 

As of  December 31, 2017 and  2016, we had  $67.2 million and $17.9  million of outstanding borrowings under our revolving loan commitments, 
respectively. The interest rate on our outstanding borrowings was 3.26% and 2.09% at December 31, 2017 and 2016, respectively. As of December 
31,  2017,  after  outstanding  borrowings  and  $11.5  million  of  undrawn  letters  of  credit  backed  by  the  Credit  Agreement,  our  available  borrowing 
capacity was $521.3 million.  

Non-Recourse Property Debt (Asset Management Business) 

The partnerships served by the Asset Management business finance apartment communities using property-level,  non-recourse, long-dated, 
fixed-rate, amortizing debt. The following table summarizes non-recourse property debt related to assets classified as held for use at December 31,

In  connection  with  our  redevelopment,  development  and  capital  improvement  activities,  we  have  entered  into  various  construction-related 
contracts  and  we  have  made  commitments  to  complete  redevelopment  of  certain  apartment  communities,  pursuant  to  financing  or  other 
arrangements. As of December  31,  2017, our commitments related to these capital activities totaled approximately  $91.1 million, most of which we 
expect to incur during the next 12 months.  

We enter into certain commitments for future purchases of goods and services in connection with the operations of our apartment communities. 

Those commitments generally have terms of one year or less and reflect expenditure levels comparable to our historical expenditures. 

Tax Credit Arrangements 

For  various  consolidated  partnerships  served  by  our  Asset  Management  business,  we  are  required  to  manage  the  partnerships  and  related 
apartment communities in compliance with various laws, regulations and contractual provisions that apply to historic and low-income housing tax 
credit syndication arrangements. In some instances, noncompliance with applicable requirements could result in projected tax benefits not being 
realized by the limited partners in these partnerships and would require a refund or reduction of investor capital contributions, which are reported as 
deferred income in our consolidated balance sheets until such time as our obligation to deliver tax benefits is relieved. The remaining compliance 
periods for the tax credit syndication arrangements range from less than one year to eight years. We do not anticipate that any material refunds or 
reductions of investor capital contributions will be required in connection with these arrangements. 

Legal Matters 

In addition to the matters described below, we are a party to various legal actions and administrative proceedings arising in the ordinary course 
of business, some of which are covered by our general liability insurance program, and none of which we expect to have a material adverse effect on 
our consolidated financial condition, results of operations or cash flows. 

Environmental 

Various federal, state and local laws subject apartment community 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. Such laws often 
impose  liability  without  regard  to  fault  or  whether  the  owner  or  operator  knew  of,  or  was  responsible  for,  the  presence  of  such  materials.  The 
presence of, or the failure to manage or remediate properly, these materials may adversely affect occupancy at such apartment communities as well 
as  the  ability  to  sell  or  finance  such  apartment  communities.  In  addition,  governmental  agencies  may  bring  claims  for  costs  associated  with 
investigation and remediation actions. Moreover, private plaintiffs may potentially make claims for investigation and remediation costs they incur or 
for  personal  injury,  disease,  disability  or  other  infirmities  related  to  the  alleged  presence  of  hazardous  materials.  In  addition  to  potential 
environmental  liabilities  or  costs  associated  with  our  current  apartment  communities,  we  may  also  be  responsible  for  such  liabilities  or  costs 
associated with communities we acquire or manage in the future, or apartment communities we no longer own or operate. 

We are engaged in discussions with the Environmental Protection Agency, or EPA, and the Indiana Department of Environmental Management, 
or IDEM, regarding contaminated groundwater in a residential area in the vicinity of an Indiana apartment community that has not been owned by 
us  since  2008.  The  contamination  allegedly  derives  from  a  dry  cleaner  that  operated  on  our  former  property,  prior  to  our  ownership.  We  have 
undertaken a voluntary remediation of the dry cleaner contamination under IDEM’s  

F-26 

 
 
  
Table of Contents 

oversight, and in previous years accrued our share of the then-estimated cleanup and abatement costs. In 2016, EPA listed our former community 
and a number of residential communities in the vicinity on the National Priorities List, or NPL (i.e. as a Superfund site), and IDEM has formally 
sought to terminate us from the voluntary remediation program. We continue discussions with both agencies on potential long-term solutions. We 
have filed a formal appeal of the EPA listing and the IDEM termination of us from the voluntary remediation program. Although the outcome of 
these processes are uncertain, we do not expect their resolution to have a material adverse effect on our consolidated financial condition, results of 
operations or cash flows. 

We  also  have  been  contacted  by  regulators  and  the  current  owner  of  a  property  in  Lake  Tahoe,  California  regarding  environmental  issues 
allegedly  stemming  from  the  historic  operation  of  a  dry  cleaner.  An  entity  owned  by  us  was  the  former  general  partner  of  a  now-dissolved 
partnership that previously owned a site that was used for dry cleaning. That entity and the current property owner have been remediating the dry 
cleaner site since 2009, under the oversight of the Lahontan Regional Water Quality Control Board, or Lahontan. In May 2017, Lahontan issued a 
final cleanup and abatement order that names four potentially-responsible parties, acknowledges that there may be additional responsible parties, 
and  requires  the  named  parties  to  perform  additional  groundwater  investigation  and  corrective  actions  with  respect  to  onsite  and  offsite 
contamination. We are appealing the final order while simultaneously complying with it. Although the outcome of this process is uncertain, we do 
not expect its resolution to have a material adverse effect on our consolidated financial condition, results of operations or cash flows. 

We have determined that our legal obligations to remove or remediate certain potentially hazardous materials may be conditional asset retirement 
obligations, as defined in GAAP. Except in limited circumstances where the asset retirement activities are expected to be performed in connection 
with a planned construction project or apartment community casualty, we believe that the fair value of our asset retirement obligations cannot be 
reasonably estimated due to significant uncertainties in the timing and manner of settlement of those obligations. Asset retirement obligations that 
are reasonably estimable as of December 31, 2017, are immaterial to our consolidated financial condition, results of operations and cash flows. 

Operating Leases  

We are obligated under non-cancelable operating leases for office space. We are also obligated under non-cancelable operating leases for the 
ground under certain of our apartment communities with remaining terms ranging from 46 years  to 70 years. Approximate minimum annual rental 
payments under operating leases are as follows (in thousands):

Note 6 — Aimco Equity 

Preferred Stock 

At December 31, 2017 and 2016, Aimco had a single class of perpetual preferred stock outstanding, its Class A Cumulative Preferred Stock, with 

5,000,000 shares authorized, issued and outstanding and with a balance of $125.0 million as of December 31, 2017 and 2016.  

Aimco’s Class A Preferred Stock has a $0.01 per share par value, is senior to Aimco’s Common Stock, has a liquidation preference per share of 
$25.00  and  is  redeemable  at  our  option  on  or  after  May 17,  2019.  The  holders  of  Preferred  Stock  are  generally  not  entitled  to  vote  on  matters 
submitted to stockholders. Dividends at an annual rate of 6.88% are subject to declaration by Aimco’s Board of Directors.

During  the  year  ended  December  31,  2016,  Aimco  redeemed  all  of  the  outstanding  shares  of  its  Class  Z  Cumulative  Preferred  Stock  at  a 
redemption  value  of  $34.8  million.  We  reflected  the  $0.7  million  excess  of  the  redemption  value  over  the  carrying  amount  and  $1.3  million  of 
previously deferred issuance costs as an adjustment of net income attributable to preferred stockholders for the year ended December 31, 2016.  

During the year ended  December 31, 2015, Aimco redeemed the remaining outstanding shares, or $27.0 million in liquidation preference, of its 
Series  A  Community  Reinvestment  Act,  or  CRA,  Preferred  Stock.  We  reflected  $0.7  million  of  issuance  costs  as  an  adjustment  of  net  income 
attributable to preferred stockholders for the year ended December 31, 2015.  

In connection with these redemptions of Aimco preferred stock, the Aimco Operating Partnership redeemed from Aimco a number of Partnership 

Preferred Units equal to the number of shares redeemed or repurchased by Aimco.  

Common Stock 

During the years ended December 31, 2017, 2016 and 2015, Aimco declared dividends per common share of $1.44, $1.32 and $1.18, respectively.  

During the year ended December  31,  2015, Aimco issued  9,430,000 shares of its Common Stock, par value  $0.01 per share, in an underwritten 
public offering, for net proceeds per share of $38.90. The offering generated net proceeds to Aimco of $366.6 million, net of issuance costs. Aimco 
contributed the net proceeds from the sale of Common Stock to the Aimco Operating Partnership in exchange for a number of common partnership 
units equal to the number of shares of Common Stock issued.  

Registration Statements 

Aimco and the Aimco Operating Partnership have a shelf registration statement that provides for the issuance of debt and equity securities by 

Aimco and debt securities by the Aimco Operating Partnership.  

Note 7 — Partners’ Capital 

Partnership Preferred Units Owned by Aimco 

At December  31,  2017 and 2016, the Aimco Operating Partnership had outstanding preferred units in classes and amounts similar to Aimco’s 
Preferred  Stock  described  in  Note  6,  or  Partnership  Preferred  Units.  All  of  these  Partnership  Preferred  Units  were  owned  by  Aimco  during  the 
periods presented. 

The Partnership Preferred Units are senior to the Aimco Operating Partnership’s common partnership units. The Partnership Preferred Units do 
not  have  voting  rights,  except  the  right  to  approve  certain  changes  to  the  Aimco  Operating  Partnership’s  Partnership  Agreement  that  would 
adversely affect holders of such class of units. Distributions on Partnership Preferred Units are subject to being declared by the General Partner. 
The Partnership Preferred Units are redeemable by the Aimco Operating Partnership only in connection with a concurrent redemption by Aimco of 
the corresponding Aimco Preferred Stock held by unrelated parties.  

As  discussed  in  Note  6,  during  the  years  ended  December  31,  2016  and  2015,  Aimco  completed  various  Preferred  Stock  redemptions.  In 
connection with these redemptions, the Aimco Operating Partnership redeemed from Aimco a corresponding number of Partnership Preferred Units.

Each class of preferred OP Units is currently redeemable at the holders’ option. The Aimco Operating Partnership, at its sole discretion, may 
settle such redemption requests in cash or cause Aimco to issue shares of its Common Stock with a value equal to the redemption price. In the 
event  the  Aimco  Operating  Partnership  requires  Aimco  to  issue  shares  of  Common  Stock  to  settle  a  redemption  request,  the  Aimco  Operating 
Partnership would issue to Aimco a corresponding number of common partnership units. The Aimco Operating Partnership has a redemption policy 
that requires cash settlement of redemption requests for the preferred OP Units, subject to limited exceptions. Subject to certain conditions, the 
Class Four and Class Six preferred OP Units may be converted into common OP Units. 

These redeemable units are classified within temporary equity in Aimco’s consolidated balance sheets and within temporary capital in the Aimco 

Operating Partnership’s consolidated balance sheets. 

During the years ended December 31, 2017, 2016 and 2015, approximately 67,000, 69,000 and 700 preferred OP Units, respectively, were redeemed 

in exchange for cash, and no preferred OP Units were redeemed in exchange for shares of Aimco Common Stock. 

The Class Ten preferred OP Units were issued as partial consideration for an acquisition during the year ended December 31, 2016.  

The following table presents a reconciliation of the Aimco Operating Partnership’s preferred OP Units during the years ended  December 31,

In the Aimco Operating Partnership’s consolidated balance sheets, the common partnership units held by Aimco are classified within Partners’ 
Capital as General Partner and Special Limited Partner capital and the common OP Units are classified within Limited Partners’ capital. In Aimco’s 
consolidated  balance  sheets,  the  common  OP  Units  are  classified  within  permanent  equity  as  common  noncontrolling  interests  in  the  Aimco 
Operating Partnership. 

Common partnership units held by Aimco are not redeemable whereas common OP Units are redeemable at the holders’ option, subject to certain 

restrictions, on the basis of one common OP Unit for either one share of Common Stock or cash equal to the fair

value of a share of Common Stock at the time of redemption. Aimco has the option to deliver shares of Common Stock in exchange for all or any 
portion of the common OP Units tendered for redemption. When a limited partner redeems a common OP Unit for Common Stock, Limited Partners’ 
capital is reduced and the General Partner and Special Limited Partners’ capital is increased.  

The holders of the common OP Units receive distributions, prorated from the date of issuance, in an amount equivalent to the dividends paid to 
holders of Common Stock. During the years ended December 31, 2017, 2016 and 2015, the Aimco Operating Partnership declared distributions per 
common unit of $1.44, $1.32 and $1.18, respectively.  

During  the  years  ended  December  31,  2017,  2016  and  2015,  approximately  98,000,  248,000  and  112,000  common  OP  Units,  respectively,  were 

redeemed in exchange for cash, and no common OP Units were redeemed in exchange for shares of Common Stock.  

Note 8 — Share-Based Compensation 

We have a stock award and incentive program to attract and retain officers and independent directors. As of December 31, 2017, approximately 
0.4 million shares were available for issuance under our 2015 Stock Award and Incentive Plan. The total number of shares available for issuance 
under this plan may be increased by an additional 0.7 million shares to the extent of any forfeiture, cancellation, exchange, surrender, termination or 
expiration of an award outstanding under our 2007 Stock Award and Incentive Plan. Awards under the 2015 plan may be in the form of incentive 
stock options, non-qualified stock options and restricted stock, or other types of awards as authorized under the plan.  

Our plans are administered by the Compensation and Human Resources Committee of Aimco’s Board of Directors. In the case of stock options, 

the exercise price of the options granted may not be less than the fair market value of a share of Common Stock at the date of grant. 

Total compensation cost recognized for stock based awards was $9.3 million, $8.6 million and $7.2 million for the years ended December 31, 2017, 
2016 and 2015, respectively. Of these amounts, $1.4 million, $1.0 million and $0.5 million, respectively, were capitalized. At December 31, 2017, total 
unvested compensation cost not yet recognized was $11.8 million. We expect to recognize this compensation over a weighted average period of 
approximately 1.6 years.  

We have granted five different types of awards that are outstanding as of December  31,  2017. We have granted stock options and restricted 
stock awards that are subject to time-based vesting and require continuous employment, typically over a period of four years from the grant date, 
and we refer to these awards as Time-Based Stock Options and Time-Based Restricted Stock, respectively. We have also granted stock options, 
restricted stock awards and long-term incentive partnership units, or LTIP units, that vest conditioned on Aimco’s total shareholder return, or TSR, 
relative to the NAREIT Apartment Index (60% weighting) and the MSCI US REIT Index (40% weighting) over a forward-looking performance period 
of three years. We refer to these awards as TSR Stock Options, TSR Restricted Stock and TSR LTIP units. Earned TSR-based awards, if any, will 
vest 50% on each of the third anniversary and fourth anniversary of the grant date, based on continued employment. The term of Time-Based Stock 
Options and TSR Stock Options is generally ten years from the date of grant. 

We recognize compensation cost associated with Time-Based awards ratably over the requisite service periods, which are typically four years. 
We recognize compensation cost related to the TSR-based awards, which have graded vesting periods, over the requisite service period for each 
separate vesting tranche of the award, commencing on the grant date. The value of the TSR-based awards take into consideration the probability 
that the market condition will be achieved; therefore previously recorded compensation cost is not adjusted in the event that the market condition is 
not achieved and awards do not vest.

We estimated the fair value of TSR-based awards granted in 2017, 2016 and 2015 using a Monte Carlo model using the assumptions set forth in 

the table below.  

The risk-free interest rate reflects the annualized yield of a zero coupon U.S. Treasury security with a term equal to the expected term of the 
option. The expected dividend yield reflects expectations regarding cash dividend amounts per share paid on Aimco’s Common Stock during the 
expected term of the option. Expected volatility reflects an average of the historical volatility of Aimco’s Common Stock during the historical period 
commensurate with the expected term of the options that ended on the date of grant, and the implied volatility is calculated from observed call 
option contracts closest to the expected term. The derived vesting period of TSR Restricted Stock and TSR LTIP units was determined based on the 
graded vesting terms. The expected term of the TSR-options was based on historical option exercises and post-vesting terminations. The midpoints 
of our valuation assumptions for the 2017, 2016 and 2015 grants were as follows:

In December 2017, the U.S. Congress passed the Tax Cuts and Jobs Act, or the 2017 Act, which is effective for years beginning with 2018. The 
2017 Act provides for a reduction in the federal income tax rate. In accordance with GAAP, we revalued our deferred tax assets and liabilities as of 
December 31, 2017. We have not completed our accounting for the tax effects of enactment of the 2017 Act; however, we have made a reasonable 
estimate of the effects on our existing deferred tax balances, resulting in our recognition of a net tax benefit of $15.9 million.  

At December 31, 2017, we had federal and state net operating loss carryforwards, or NOLs, for which the deferred tax asset was approximately 
$9.5 million, before a valuation allowance of $6.6 million. The NOLs expire in years 2018 to 2033. Subject to certain separate return limitations, we 
may use these NOLs to offset a portion of state taxable income generated by our TRS entities.  

As  of  December  31,  2017,  we  had  low-income  housing  and  rehabilitation  tax  credit  carryforwards  and  corresponding  deferred  tax  assets  of 
approximately $73.5 million for income tax purposes that expire in years 2024 to 2037. In light of the lower federal tax rate under the 2017 Act, our 
TRS entities must generate more taxable income in future years to utilize tax credit carryforwards, which are recorded as deferred tax assets. As a 
result,  during  the  year  ended  December  31,  2017,  we  recognized  a  partial  valuation  allowance  of  $15.4  million  against  the  deferred  tax  assets 
associated with low-income housing and rehabilitation tax credit carryforwards. 

At December 31, 2017, we had a real estate partnership basis difference of $4.4 million related to the 2017 impairment loss recognized related to 

the La Jolla Cove property discussed in Note 3, for which we have recognized a full valuation allowance.

Because the statute of limitations has not yet elapsed, our United States federal income tax returns for the year ended December 31, 2013 and 
subsequent years and certain of our State income tax returns for the year ended December 31, 2013 and subsequent years are currently subject to 
examination by the IRS or other taxing authorities. If recognized, the unrecognized benefit would affect the effective rate.  

In 2014, the IRS initiated an audit of the Aimco Operating Partnership’s 2011 and 2012 tax years. This audit remains in process as of December 

31, 2017. We do not believe the audit will have any material effect on our unrecognized tax benefits, financial condition or results of operations. 

Our  policy  is  to  include  any  interest  and  penalties  related  to  income  taxes  within  the  income  tax  line  item  in  our  consolidated  statements  of 

operations.

In accordance with the accounting requirements for stock-based compensation, we may recognize tax benefits in connection with the exercise of 
stock options by employees of our TRS entities and the vesting of restricted stock awards. As of  December  31,  2017, all cumulative excess tax 
benefits  from  employee  stock  option  exercises  and  vested  restricted  stock  awards  had  been  realized.  As  further  discussed  in  the  Accounting 
Pronouncements Adopted in the Current Year heading in Note 2, in 2017 we began recognizing the tax effects related to stock-based compensation 
through earnings in the period the compensation was recognized. 

Significant components of the income tax benefit or expense are as follows and are classified within income tax benefit in income before gain on

(1)   As a result of the 2017 Act, Alternative Minimum Tax credits that are not used will be refunded before 2022, therefore in 2017 we reclassified $2.7 million
in AMT credits from deferred tax assets to receivables, which is included in other assets on our consolidated balance sheet, resulting in a net current federal 
tax benefit. 

Consolidated income or loss subject to tax consists of pretax income or loss of our TRS entities and income and gains retained by the REIT. For 
the years ended December 31, 2017, 2016 and 2015, we had consolidated net loss subject to tax of $55.6 million, net income subject to tax of $109.3 
million and net loss subject to tax of $31.3 million, respectively.

(1)  Includes the establishment of a deferred tax asset related to partnership basis difference when it became apparent that it would reverse in the foreseeable 

future. This deferred tax asset is fully reserved in the valuation allowance described below. 

(2)  2016 and 2015 include the effect of intercompany asset transfers between the Aimco Operating Partnership and TRS entities, for which tax was deferred 
and recognized as the assets affected GAAP income or loss, for example, through depreciation, impairment, or upon the sale of the asset to a third-party. 
Effective January 1, 2017, we adopted a new accounting standard applicable to intercompany asset transfers. As a result, the accumulated unrecognized 
deferred tax expense associated with historical intercompany transfers was recognized as a cumulative effect adjustment through retained earnings at that 
time, as further described in Note 2.

Aimco  and  the  Aimco  Operating  Partnership  calculate  basic  earnings  per  common  share  and  basic  earnings  per  common  unit  based  on  the 
weighted average number of shares of Common Stock and common partnership units and participating securities outstanding, and calculate diluted 
earnings per share and diluted earnings per unit taking into consideration dilutive common stock and common partnership unit equivalents and 
dilutive convertible securities outstanding during the period.  

Our  common  stock  equivalents  and  common  partnership  unit  equivalents  include  options  to  purchase  shares  of  Common  Stock,  which,  if 
exercised, would result in Aimco’s issuance of additional shares and the Aimco Operating Partnership’s issuance to Aimco of additional common 
partnership  units  equal  to  the  number  of  shares  purchased  under  the  options.  These  equivalents  also  include  unvested  TSR  Restricted  Stock 
awards that do not meet the definition of participating securities, which would result in the issuance of additional common shares and common 
partnership units equal to the number of shares that vest. The effect of these securities was dilutive for the years ended December 31, 2017, 2016, 
and 2015, and accordingly has been included in the denominator for calculating diluted earnings per share and unit during these periods.  

Our Time-Based Restricted Stock awards receive dividends similar to shares of Common Stock and common partnership units prior to vesting 
and  our  TSR  LTIP  units  receive  a  percentage  of  the  distributions  paid  to  common  partnership  units  prior  to  vesting.  These  dividends  and 
distributions are not forfeited in the event the awards do not vest. Therefore, the unvested restricted shares and units related to these awards are 
participating securities. The effect of participating securities is included in basic and diluted earnings per share and unit computations using the 
two-class method of allocating distributed and undistributed earnings when the two-class method is more dilutive than the treasury stock method. 
At  December  31,  2017,  2016  and  2015,  there  were  0.2  million,  0.2  million  and  0.3  million  shares  of  unvested  participating  restricted  securities, 
respectively.  

As discussed in  Note 7, the Aimco Operating Partnership has various classes of preferred OP Units, which may be redeemed at the holders’ 
option. The Aimco Operating Partnership may redeem these units for cash, or at its option, shares of Common Stock. As of December  31,  2017, 
these preferred OP Units were potentially redeemable for approximately 2.3 million shares of Common Stock (based on the period end market price), 
or cash. The Aimco Operating Partnership has a redemption policy that requires cash settlement of redemption requests for the preferred OP Units, 
subject  to  limited  exceptions.  Accordingly,  we  have  excluded  these  securities  from  earnings  per  share  and  unit  computations  for  the  periods 
presented above, and we expect to exclude them in future periods. 

Note 11 — Fair Value Measurements 

Recurring Fair Value Measurements 

We measure at fair value on a recurring basis our investment in the securitization trust that holds certain of our property debt, which we classify 
as available for sale (AFS) debt securities, and our interest rate swaps, both of which are classified within Level 2 of the GAAP fair value hierarchy.  

Our  investments  classified  as  AFS  are  presented  within  other  assets  in  the  accompanying  consolidated  balance  sheets.  We  hold  several 

positions in the securitization trust that pay interest currently and we also hold the first loss position in the securitization

trust, which accrues interest over the term of the investment. We are accreting the discount to the $100.9 million face value of the investments into 
interest  income  using  the  effective  interest  method  over  the  remaining  expected  term  of  the  investments,  which  as  of  December  31,  2017,  was 
approximately  3.4  years.  Our  amortized  cost  basis  for  these  investments,  which  represents  the  original  cost  adjusted  for  interest  accretion  less 
interest payments received, was  $77.7 million and $72.5 million at December  31,  2017 and 2016, respectively. We estimated the fair value of these 
investments to be $82.8 million and $76.1 million at December 31, 2017 and 2016, respectively.  

We estimate the fair value of these investments using an income and market approach with primarily observable inputs, including yields and 
other information regarding similar types of investments, and adjusted for certain unobservable inputs specific to these investments. The fair value 
of the positions that pay interest currently typically moves in an inverse relationship with movements in interest rates. The fair value of the first loss 
position is primarily correlated to collateral quality and demand for similar subordinate commercial mortgage-backed securities.  

Certain  consolidated  partnerships  served  by  our  Asset  Management  business  have  entered  into  interest  rate  swap  agreements,  which  limit 
exposure to interest rate risk on the partnerships’ debt by effectively converting the interest from a variable rate to a fixed rate. We estimate the fair 
value of interest rate swaps using an income approach with primarily observable inputs, including information regarding the hedged variable cash 
flows and forward yield curves relating to the variable interest rates on which the hedged cash flows are based.  

The following table sets forth a summary of changes in fair value in the interest rate swaps (in thousands): 

Beginning balance

Realized losses on derecognition of interest rate swaps included in earnings represents previously unrealized losses related to an interest rate 
swap to which the partnership owning the final Napico property was a party. We wrote off the accumulated other comprehensive income related to 
this swap in conjunction with the derecognition of the property’s assets and liabilities as discussed in Note 3. 

As of December 31, 2017 and  2016, the remaining interest rate swaps, exclusive of the derecognized Napico interest rate swap, had aggregate 
notional amounts of $22.0 million and $22.4 million, respectively. As of December 31, 2017, these swaps had a weighted average remaining term of 
6.0 years. We have designated these interest rate swaps as cash flow hedges. The fair value of these swaps is presented within accrued liabilities 
and other related to the Asset Management business within our consolidated balance sheets, and we recognize any changes in the fair value as an 
adjustment of accumulated other comprehensive loss within equity and partners’ capital to the extent of their effectiveness.  

If  the  forward  rates  at  December  31,  2017,  remain  constant,  we  estimate  that  during  the  next  12  months,  we  would  reclassify  into  earnings 
approximately  $0.3  million  of  the  unrealized  losses  in  accumulated  other  comprehensive  loss.  If  market  interest  rates  increase  above  the  3.26% 
weighted average fixed rate under these interest rate swaps we will benefit from net cash payments due to us from our counterparty to the interest 
rate swaps.

Fair Value Disclosures 

We believe that the carrying values of the consolidated amounts of cash and cash equivalents, receivables and payables approximates their fair 
value at December 31, 2017 and 2016, due to their relatively short-term nature and high probability of realization. The estimated fair value of total 
indebtedness associated with our Real Estate portfolio was approximately $3.9 billion and $3.7 billion at December 31, 2017 and 2016, respectively, 
as  compared  to  carrying  amounts  of $3.9  billion  and  $3.6  billion,  respectively.  The  carrying  amounts  of  the  non-recourse  property  debt  of  the 
consolidated partnerships served by our Asset Management business approximated its estimated fair value at December 31, 2017 and December 31, 
2016. We estimate the fair value of our consolidated debt using an income and market approach, including comparison of the contractual terms to 
observable and unobservable inputs such as market interest rate risk spreads, contractual interest rates, remaining periods to maturity, collateral 
quality and loan to value ratios on similarly encumbered apartment communities within our portfolio. We classify the fair value of our consolidated 
debt within Level 3 of the GAAP valuation hierarchy based on the significance of certain of the unobservable inputs used to estimate their fair 
values. 

Note 12 — Business Segments 

During  the  year  ended  December  31,  2017,  we  revised  the  information  regularly  reviewed  by  our  chief  executive  officer,  who  is  our  chief 
operating decision maker, to assess our operating performance. Apartment communities are classified as either part of our Real Estate portfolio or as 
those owned by partnerships served by our Asset Management business.  

Our  chief  operating  decision  maker  uses  proportionate  property  net  operating  income  to  assess  the  operating  performance  of  our  apartment 
communities. Proportionate property net operating income reflects our share of rental and other property revenues less direct property operating 
expenses,  including  real  estate  taxes,  for  consolidated  apartment  communities  we  own  and  manage.  As  of  December  31,  2017,  for  segment 
performance evaluation, our Real Estate segment included 132 consolidated apartment communities with 36,762 apartment homes and excluded four 
apartment communities with 142 apartment homes that we neither manage nor consolidate. 

As of December 31, 2017, through our Asset Management business we also held nominal ownership positions in consolidated partnerships that 
own 46 low-income housing tax credit apartment communities with 6,898 apartment homes. Neither the results of operations nor the assets of these 
partnerships  and  apartment  communities  are  quantitatively  material;  therefore,  we  have  one  reportable  segment,  Real  Estate.  The  results  of 
operations for the years ended December 31, 2016 and 2015, and the segment assets as of December 31, 2016, shown below have been revised to 
reflect the change in our reportable segments.  

The  following  tables  present  the  revenues,  net  operating  income  and  income  before  gain  on  dispositions  of  our  Real  Estate  segment  on  a 
proportionate basis (excluding amounts related to apartment communities sold or classified as held for sale as of December 31, 2017) for the years 
ended December 31, 2017, 2016 and 2015 (in thousands):

For the years ended December 31, 2017, 2016 and 2015, capital additions related to our Real Estate segment totaled $338.0 million, $321.0 million 

and $340.3 million, respectively. 

Note 13 — Variable Interest Entities 

Generally, a variable interest entity, or VIE, is a legal entity in which the equity investors do not have the characteristics of a controlling financial 
interest or the equity investors lack sufficient equity at risk for the entity to finance its activities without additional subordinated financial support. 
A limited partnership is considered a VIE when the majority of the limited partners unrelated to the general partner possess neither the right to 
remove the general partner without cause, nor certain rights to participate in the decisions that most significantly affect the financial results of the 
partnership. In determining whether we are the primary beneficiary of a VIE, we consider qualitative and quantitative factors, including, but not 
limited  to:  which  activities  most  significantly  impact  the  VIE’s  economic  performance  and  which  party  controls  such  activities;  the  amount  and 
characteristics of our investment; the obligation or likelihood for us or other investors to provide financial support; and the similarity with and 
significance  to  our  business  activities  and  the  business  activities  of  the  other  investors.  Significant  judgments  related  to  these  determinations 
include estimates about the current and future fair values and performance of real estate held by these VIEs and general market conditions. 

Aimco consolidates the Aimco Operating Partnership, which is a VIE for which Aimco is the primary beneficiary. Aimco, through the Aimco 

Operating Partnership, consolidates all VIEs for which it is the primary beneficiary. 

All of the VIEs we consolidate own interests in one or more apartment communities. VIEs that own apartment communities we classify as part of 
our Real Estate segment are typically structured to generate a return for their partners through the operation and ultimate sale of the communities. 
We are the primary beneficiary in the limited partnerships in which we are the sole decision maker and have a substantial economic interest.  

Certain partnerships served by our Asset Management business own interests in low-income housing tax credit apartment communities that are 
structured to provide for the pass-through of tax credits and tax deductions to their partners and are VIEs. We hold a nominal ownership position in 
these partnerships, generally one percent or less. As general partner in these partnerships, we are the sole decision maker and we receive fees and 
other payments in return for the asset management and other services we provide and thus share in the economics of the partnerships, and as such, 
we are the primary beneficiary of these partnerships. The table below summarizes information regarding VIEs that are consolidated by the Aimco 
Operating Partnership:

CHIEF EXECUTIVE OFFICER CERTIFICATION 

I, Terry Considine, certify that:  

1. 

I have reviewed this annual report on Form 10-K of Apartment Investment and Management Company;

2.  Based on my knowledge, this report does not contain any untrue statement of a material fact or omit to state a material fact necessary to make 
the statements made, in light of the circumstances under which such statements were made, not misleading with respect to the period covered 
by this report; 

3.  Based on my knowledge, the financial statements, and other financial information included in this report, fairly present in all material respects 

the financial condition, results of operations and cash flows of the registrant as of, and for, the periods presented in this report; 

4.  The registrant’s other certifying officers and I are responsible for establishing and maintaining disclosure controls and procedures (as defined 
in Exchange Act Rules 13a-15(e) and 15d-15(e)) and internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 
15d-15(f)) for the registrant and have: 

(a)  Designed  such  disclosure  controls  and  procedures,  or  caused  such  disclosure  controls  and  procedures  to  be  designed  under  our 
supervision, to ensure that material information relating to the registrant, including its consolidated subsidiaries, is made known to us by 
others within those entities, particularly during the period in which this report is being prepared; 

(b)  Designed such internal control over financial reporting, or caused such internal control over financial reporting to be designed under our 
supervision, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for 
external purposes in accordance with generally accepted accounting principles; 

(c)  Evaluated the effectiveness of the registrant’s disclosure controls and procedures and presented in this report our conclusions about the 

effectiveness of the disclosure controls and procedures, as of the end of the period covered by this report based on such evaluation; and 

(d)  Disclosed in this report any change in the registrant’s internal control over financial reporting that occurred during the registrant’s most 
recent fiscal quarter (the registrant’s fourth fiscal quarter in the case of an annual report) that has materially affected, or is reasonably likely 
to materially affect, the registrant’s internal control over financial reporting; and 

5.  The registrant’s other certifying officers and I have disclosed, based on our most recent evaluation of internal control over financial reporting, 
to the registrant’s auditors and the audit committee of the registrant’s board of directors (or persons performing the equivalent functions): 

(a)  All  significant  deficiencies  and  material  weaknesses  in  the  design  or  operation  of  internal  control  over  financial  reporting  which  are 

reasonably likely to adversely affect the registrant’s ability to record, process, summarize and report financial information; and 

(b)  Any fraud, whether or not material, that involves management or other employees who have a significant role in the registrant’s internal 

control over financial reporting.
