PART I

ITEM 1. BUSINESS. 

BUSINESS OVERVIEW

We help organizations around the world protect their information, reduce storage costs, comply with regulations, facilitate corporate 
disaster recovery, and better use their information and IT infrastructure for business advantages, regardless of its format, location 
or life cycle stage. We do this by storing physical records and data backup media, offering information management solutions, and 
providing data center space for enterprise-class colocation and hyperscale deployments. We offer comprehensive records and 
information management services and data management services, along with the expertise and experience to address complex 
storage and information management challenges such as rising storage rental costs, legal and regulatory compliance, and disaster 
recovery requirements. We provide secure and reliable data center facilities to protect digital information and ensure the continued 
operation of our customers’ IT infrastructure, with reliable and flexible deployment options.

Founded in an underground facility near Hudson, New York in 1951, Iron Mountain Incorporated, a Delaware corporation, has 
approximately 225,000 customers in a variety of industries in 63 countries around the world, as of December 31, 2021. We 
currently serve customers across an array of market verticals - commercial, legal, financial, healthcare, insurance, life sciences, 
energy, business services, entertainment and government organizations, including approximately 95% of the Fortune 1000. As of 
December 31, 2021, we employed approximately 25,000 people. We are listed on the New York Stock Exchange (the “NYSE”) and 
are a constituent of the Standard & Poor’s 500 Index and the MSCI REIT index. As of December 31, 2021, we were number 605 on 
the Fortune 1000.

We have been organized and have operated as a REIT beginning with our taxable year ended December 31, 2014.

BUSINESS STRATEGY

OVERVIEW

Our company has been a market leader in the physical ecosystem supporting information storage and retrieval, as most 
businesses have relied on paper documents or computer tapes to store their valuable information. Over time, customers are 
increasing their digital information, with the new information storage ecosystem being a hybrid of physical and digital mediums. We 
are a different company than the one we have been historically. The strategic journey we are on is driving this change and our 
focus remains on four pillars outlined below to grow our business.

Continued growth in physical storage 
through revenue management as well 
as volume growth achieved in faster 
growing emerging markets and 
consumer and adjacent business 
growth in developed markets

• We are establishing and enhancing leadership positions in higher-growth 

markets such as central and eastern Europe, Latin America, Asia and Africa, 
through both organic expansion and acquisitions in countries where GDP growth 
is faster and outsourcing information management is at an earlier stage.

• We continue to identify, acquire, incubate and scale complementary businesses 
and products to support our long-term growth objectives and drive solid returns 
on invested capital. These opportunities include our digital services, Secure IT 
Asset Disposition and our Entertainment Services, Fine Arts and Consumer 
Storage (each as defined below) businesses.

Utilizing our global scale as well as 70 
years of customer trust to deliver 
differentiated data center offerings

• We have made significant progress in scaling our Global Data Center Business 
through acquisitions and organic growth, with 19 operating data centers across 
16 global markets. 

• As of December 31, 2021, approximately 89% of our data center capacity was 
leased. With total potential capacity of 604 megawatts ("MW") in land and 
buildings currently owned or operated by us, we are among the largest global 
data center operators.

Developing and offering new products 
and services that allow our customers 
to achieve reliable and secure 
information management solutions in 
an increasingly hybrid physical and 
digital world

• Our customers are faced with navigating a more complex regulatory 

environment, and one in which hybrid physical and digital solutions have 
become the norm. Our strategy is underpinned by our persistent focus on best-
in-class customer experience, as we continue to seek innovative solutions to 
help our customers progress on their journey from physical storage to a digital 
ecosystem.

Increased investment in our business 
and customer-centric solutions

• We have established an investment strategy to fuel our growth. The investments 
are enabled by the success of Project Summit and informed by our established 
leadership position in the physical storage business, expanding services, and 
our significant progress in the Global Data Center business. 

PROJECT SUMMIT

In October 2019, we announced our global program ("Project Summit") designed to better position us for future growth and 
achievement of our strategic objectives. We expanded Project Summit during the first quarter of 2020 to include additional 
opportunities to streamline our business and operations, as well as accelerated the timing of certain opportunities previously 
identified. As a result of this initiative, we simplified our global structure, rebalanced resources to focus on higher growth areas, 
realigned our management structure to create a more dynamic, agile organization, and made investments to enhance the customer 
experience. All Project Summit activities were completed in 2021, resulting in $375.0 million in annual Adjusted EBITDA benefits of 
which $165.0 million were delivered in 2020 and $160.0 million were delivered in 2021, with the remainder to come in 2022. Project 
Summit charges totaled approximately $450.0 million since the program's inception. For further details on Project Summit, see the 
"Overview" section of “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” in this 
Annual Report.

BUSINESS SEGMENTS

The amount of revenues derived from our business segments and other relevant data, including financial information about 
geographic areas and product and service lines, for the years ended December 31, 2021, 2020 and 2019, are set forth in Note 11 
to Notes to Consolidated Financial Statements included in this Annual Report.

practices. We are able to offer this service in over 30 countries.

convenient and seamless consumer storage experience.

Part I

BUSINESS ATTRIBUTES

Our business has the following attributes: 

Large, Diversified,
Global Business

The world’s most heavily regulated organizations trust us with the storage of their records. Our 
mission-critical storage offerings and related services generated approximately $4.5 billion in 
annual revenue in 2021. Our business has a highly diverse customer base of approximately 
225,000 customers - with no single customer accounting for more than approximately 1% of 
revenue during the year ended December 31, 2021 - and operates in 63 countries globally. This 
presents a significant cross-sell opportunity for our Global Data Center, Global Digital Solutions 
and Global Secure IT Asset Disposition businesses.

Recurring, Durable 
Revenue Stream

We generate a majority of our revenues from contracted storage rental fees, via agreements that 
generally range from one to five years in length. Historically, in our Records Management 
business, we have seen strong customer retention (of approximately 98%) and solid physical 
records retention; more than 50% of physical records that entered our facilities 15 years ago are 
still with us today. We have also seen strong customer retention in our Global Data Center 
Business.

Comprehensive 
Information
Management Solution

As an S&P 500 REIT with approximately 1,450 locations globally and with offerings spanning 
physical storage, digitization solutions and digital storage, we are positioned to provide a holistic 
offering to our customers. We are able to cater to our customers’ physical and digital needs and 
to help guide their digital transformation journey. 

Significant Owner and 
Operator
of Real Estate

We operate approximately 95 million square feet of real estate worldwide. Our owned real estate 
footprint spans nearly 25 million square feet and is concentrated in major metropolitan statistical 
areas in North America, Western Europe and Latin America.

Limited Revenue 
Cyclicality

Historically, economic downturns have not significantly affected our storage rental business. Due 
to the durability of our total global physical volumes, the success of our revenue management 
initiatives, and the growth of our Global Data Center Business, we believe we can continue to 
grow organic storage rental revenue over time.

Shifting Revenue Mix

We have identified a number of areas where we see opportunity for growth as we position 
ourselves to unlock greater value for our customers. These business lines, including Data Center, 
Fine Arts and Entertainment Services, Consumer Storage and Secure IT Asset Disposition, 
represent markets with strong secular growth.

In addition, our Global Data Center business has the following attributes:

Large Data Center
Platform with Significant
Expansion Opportunity

As of December 31, 2021, we had 177 MW of leasable capacity with an additional 427 
MW under construction or held for development.

Differentiated Compliance
and Security

Efficient Access
and Flexibility

100% Green Powered
Data Centers

COMPETITION

We offer comprehensive compliance support and physical and cyber security. Our 
Security-in-Depth approach to security includes a combination of technical and human 
security measures, and experienced senior military and public sector security leaders 
oversee our security. As of December 31, 2021, our data centers comply with one of the 
most comprehensive compliance programs in the industry, including enterprise-wide 
certified ISO 14001 and 50001 environmental and energy management systems. We 
also report globally on service organizational controls, as well as global ISO 27001 
certification, and PCI-DSS compliance, and met FISMA HIGH and FedRAMP controls in 
the United States.

We have the ability to provide customers with a range of deployment options from one 
cabinet to an entire building, leveraging our global portfolio of hyperscale-ready and 
underground data centers. We also provide access to numerous carriers, cloud providers 
and peering exchanges with migration support and IT.

As of December 31, 2021, our Global Data Center platform was powered by 100% 
renewable energy, with carbon credit assistance and low power usage effectiveness 
(“PUE"). We are one of the top 30 buyers of renewable energy among the Fortune 1000 
and now offer the Green Power Pass, which allows customers to include the power they 
consume at any Iron Mountain data centers as green power in their CDP, RE100, GRI, or 
other sustainability reporting.

We compete with thousands of storage and information management services providers around the world as well as storage and 
information management services managed and operated internally by organizations. We believe that competition for records and 
information customers is based on price, reputation and reliability, quality and security of storage, quality of service and scope and 
scale of technology. While the majority of our competitors operate in only one market or region, we believe we provide a 
differentiated global offering that competes effectively in these areas.

We also compete with numerous data center developers, owners and operators, many of whom own properties similar to ours in 
some of the same metropolitan areas where our facilities are located. We believe that competition for data center customers is 
based on availability of power, security considerations, location, connectivity and rental rates, and we generally believe we compete 
effectively in each of these areas. Additionally, we believe our strong brand, global footprint and excellent commercial relationships 
enable us to compete successfully and provide significant cross-sell opportunities with our existing customer base.

HUMAN CAPITAL MANAGEMENT

EMPLOYEES

As of December 31, 2021, we employed approximately 9,000 employees in the United States and approximately 16,000 
employees outside of the United States. As of December 31, 2021, approximately 500 employees were represented by unions in 
North America and approximately 1,250 employees were represented by unions in Latin America. All union employees are currently 
under renewed labor agreements or operating under an extension agreement.

BENEFIT PROGRAMS

We provide our employees with benefits that are designed to support their overall physical, financial, emotional and social well-
being. These benefits vary by location but may include health and welfare benefits, paid time off, and programs to support financial 
security. Additionally, employees are able to access emotional well-being resources through global employee assistance programs. 
Certain unionized employees receive benefits through unions and are not eligible to participate in our benefit programs. In addition 
to base compensation and other usual benefits, a significant portion of full-time employees participate in some form of incentive-
based compensation program that provides payments based on revenues, profits or attainment of specific objectives for the unit in 
which they work.

DIVERSITY, EQUITY AND INCLUSION 

At Iron Mountain, we believe that an inclusive environment with diverse teams produces more creative solutions, results in better, 
more innovative products and services and is crucial to our efforts to attract and retain key talent. As one of our five core company 
values, Promoting Including and Teamwork is a behavior all of our employees are expected to demonstrate every day. We have 
prioritized diversity, equity and inclusion ("DEI") as part of our corporate-wide strategic goals. Steps we have taken to create and 
sustain a more diverse, equitable and inclusive environment include: hiring a Global Chief Diversity, Equity & Inclusion Officer with 
significant DEI experience to lead our cultural transformation, the path to creating an environment of inclusiveness and belonging. 
We review and revise our systems, policies and processes to assure that our structures facilitate inclusiveness and accountability. 
We ensure that our recruiting efforts reflect our diversity goals and we launch, expand and support our Employee Resource 
Groups, who meet and connect on shared characteristics and life experiences that can prove impactful to our business, our 
customers and our employees.  

COMPANY CULTURE

We recognize that an inspired culture is foundational to how we deliver on our purpose and create sustained growth and value for 
our shareholders. Iron Mountain's culture is deeply rooted in its enduring values: Act with Integrity, Own Safety and Security, Build 
Customer Value, Take Ownership and Promote Inclusion and Teamwork. While Iron Mountain is a culture of learning, 
collaboration, diversity and well-being, we know that culture overall comes down to what it feels like to work at Iron Mountain. This 
is why we celebrate our employees who consistently demonstrate Iron Mountain's values in measurable ways while inspiring others 
to do the same. We commit significant resources to sustaining a culture that enables innovation and facilitates trust, engagement, 
belonging and performance. We regularly survey our employees on a range of topics to measure our effectiveness and to obtain 
their views. In addition, headcount data and cost analyses offer insights into how and where our employees work. We use all of this 
information to refine our approach when necessary to drive increased employee engagement and success. 

COMMUNITY INVOLVEMENT

We are committed to integrating responsible and sustainable practices throughout our organization to help our operations to have a 
positive impact on the environment and the communities in which we operate. We aim to give back to the communities where we 
live and work, and believe that this commitment helps in our efforts to attract and retain employees. We offer philanthropic support 
to our global community through our Living Legacy Initiative, which is our commitment to help preserve and make accessible 
cultural and historical information and artifacts. We encourage volunteerism in the communities in which we live and work through 
our Moving Mountains volunteer program, offering paid time off for employees to help community-based and civic-minded 
organizations.

INSURANCE

For strategic risk transfer purposes, we maintain a comprehensive insurance program with insurers that we believe to be reputable 
and that have adequate capitalization in amounts that we believe to be appropriate. Property insurance is purchased on a 
comprehensive basis, including flood and earthquake (including excess coverage), subject to certain policy conditions, sublimits 
and deductibles. Property is insured based upon the replacement cost of real and personal property, including leasehold 
improvements, business income loss and extra expense. Other types of insurance that we carry, which are also subject to certain 
policy conditions, sublimits and deductibles, include medical, workers’ compensation, general liability, umbrella, automobile, 
professional, warehouse legal liability and directors’ and officers’ liability policies.

GOVERNMENT REGULATION

We are required to comply with numerous U.S. federal, state, and foreign laws and regulations covering a wide variety of subject 
matters which may have a material effect on our capital expenditures, earnings and competitive position.

For example, some of our current and formerly owned or leased properties were previously used by entities other than us for 
industrial or other purposes, or were affected by waste generated from nearby properties, that involved the use, storage, 
generation and/or disposal of hazardous substances and wastes, including petroleum products. In some instances, this prior use 
involved the operation of underground storage tanks or the presence of asbestos-containing materials. Where we are aware of 
environmental conditions that require remediation, we undertake appropriate activity, in accordance with all legal requirements. 
Although we have from time to time conducted limited environmental investigations and remedial activities at some of our former 
and current facilities, we have not undertaken an environmental review of all of our properties, including those we have acquired. 
We therefore may be potentially liable for environmental cost and may be unable to sell, rent, mortgage or use contaminated real 
estate owned or leased by us. Under various federal, state and local environmental laws, we may be liable for environmental 
compliance and remediation costs to address contamination, if any, located at owned and leased properties as well as damages 
arising from such contamination, whether or not we know of, or were responsible for, the contamination, or the contamination 
occurred while we owned or leased the property. Environmental conditions for which we might be liable may also exist at properties 
that we may acquire in the future. In addition, future regulatory action and environmental laws may impose costs for environmental 
compliance that do not exist today.

We transfer a portion of our risk of financial loss due to currently undetected environmental matters by purchasing an 
environmental impairment liability insurance policy, which covers all owned and leased locations. Coverage is provided for both 
liability and remediation costs.

In addition, we are subject to numerous U.S. federal, state, local and foreign laws and regulations relating to data privacy and 
cybersecurity, which are complex, change frequently and have tended to become more stringent over time. We devote substantial 
resources, and may in the future have to devote significant additional resources, to facilitate compliance with these laws and 
regulations, and to investigate, defend or remedy actual or alleged violations or breaches. Any failure by us to comply with, or 
remedy any violations or breaches of, these laws and regulations could result in the curtailment of certain of our operations, the 
imposition of fines and penalties, liability resulting from litigation, restrictions on our ability to carry on or expand our operations, 
significant costs and expenses and reputational harm.

For more information about laws and regulations that could affect our business, see “Item 1A. Risk Factors” included in this Annual 
Report.

ITEM 1A. RISK FACTORS.  

We face many risks. If any of the events or circumstances described below actually occur, we and our businesses, financial 
condition or results of operations could suffer, and the trading price of our debt or equity securities could decline. Our current and 
potential investors should consider the following risks and the information contained under the heading “Cautionary Note Regarding 
Forward-Looking Statements” before deciding to invest in our securities.

BUSINESS RISKS

Failure to execute our strategic growth plan may adversely impact our financial condition and results of operations.

As part of our strategic growth plan we expect to invest in our existing businesses, including records and information management 
storage and services businesses in our higher-growth markets, data centers, asset life cycle management and secure information 
technology asset disposition, consumer storage and other adjacent businesses, and in new businesses, business strategies, 
products, services, technologies and geographies, and we may selectively divest certain businesses. These initiatives may involve 
significant risks and uncertainties, including:

• our inability to maintain relationships with key customers and suppliers or to execute on our plan to incorporate the digitization of 

our customers’ records and new digital information technologies into our offerings;

•

failure to achieve satisfactory returns on new product offerings, acquired companies, joint ventures, growth initiatives, or other 
investments, particularly in markets where we do not currently operate or have a substantial presence;

• our inability to identify suitable companies to acquire, invest in or partner with;

• our inability to complete acquisitions or investments on satisfactory terms;

• our inability to structure acquisitions or investments in a manner that complies with our debt covenants and is consistent with our 

leverage ratio goals;

• challenges in managing costs to offset the impact of inflationary pressure;

•

•

increased demands on our management, operating systems, internal controls and financial and physical resources and, if 
necessary, our inability to successfully expand our infrastructure; 

incurring additional debt necessary to acquire suitable companies or make other growth investments if we are unable to pay the 
purchase price or make the investment out of working capital or the issuance of our common stock or other equity securities;

• our inability to manage the budgeting, forecasting and other process control issues presented by future growth, particularly with 

respect to operations in countries outside of the United States or in new lines of business;

•

insufficient revenues to offset expenses and liabilities associated with new investments; 

• our inability to attract, develop and retain skilled employees to lead and support our strategic growth plan, particularly in new 

businesses, technologies, products or offerings outside our core competencies; and 

• challenges in executing on our strategic growth plan within the constraints of our REIT structure, as well as remaining REIT 

compliant.

Our new ventures are inherently risky and we can provide no assurance that such strategies and offerings will be successful in 
achieving the desired returns within a reasonable timeframe, if at all, and that they will not adversely affect our business, 
reputation, financial condition, and operating results. 

We face competition from other companies to grow our business, and, as a result, we may be unable to acquire or invest in, or we 
may pay a premium purchase price for, data centers, technology and adjacent businesses and businesses in higher-growth 
markets that support our strategic growth plan, which could have an adverse effect on our results of operations and financial 
condition. 

As stored records and tapes become less active our service revenue growth and profits from related services may decline.

Our Records Management and Data Management service revenue growth is being negatively impacted by declining activity rates 
as stored records and tapes are becoming less active and more archival, and these activity levels were further negatively impacted 
by the COVID-19 pandemic. The amount of information available to customers digitally or in their own information systems has 
been steadily increasing in recent years, and we believe this trend will continue. As a result, our customers are less likely than they 
have been in the past to retrieve records and rotate tapes, thereby reducing their activity levels. At the same time, many of our 
costs related to records and tape related services remain relatively fixed. In addition, our reputation for providing secure information 
storage is critical to our success, and actions to manage cost structure, such as outsourcing certain transportation, security or other 
functions, could negatively impact our reputation and adversely affect our business. Ultimately, if we are unable to appropriately 
align our cost structure with decreased levels of service activity, our operating results could be adversely affected.

Part I

Our customers may shift from paper and tape storage to alternative technologies that may shift our revenue mix away from storage 
revenue.

We derive substantial revenues from rental fees for the storage of physical records and computer backup media and from storage 
related services. Storage volume and/or demand for our traditional storage related services may decline as our customers adopt 
alternative storage technologies or as retention requirements evolve, which may require significantly less space than traditional 
physical records and tape storage. To date, our customers’ shift from paper and tape storage to alternative technologies has not 
accelerated as a result of the COVID-19 pandemic. While volumes in our Global RIM Business segment were relatively steady in 
2021 and we expect them to remain relatively consistent in the near term, we can provide no assurance that our customers will 
continue to store most or a portion of their records as paper documents or as tapes, or that the paper documents or tapes they do 
store with us will require our storage related services at the same levels as they have in the past. A significant shift by our 
customers to storage of data through non-paper or non-tape-based technologies, whether now existing or developed in the future, 
could adversely affect our businesses. In addition, the digitization of records may shift our revenue mix from the more predictable 
storage revenue to service revenue, which is inherently more volatile.

Our future growth depends in part upon our ability to continue to effectively manage and execute on revenue management.

Over the past several years, our organic revenue growth has been positively impacted by our ability to effectively introduce, expand 
and monitor revenue management initially in our more established markets, and subsequently in our higher-growth markets. If we 
are not able to continue and effectively manage pricing, our results of operations could be adversely affected and we may not be 
able to execute on our strategic growth plan.

Changes in customer behavior with respect to destruction of records stored with us could adversely affect our business, financial 
condition and results of operations.

Over the past several years, our destruction rates, as a percentage of records stored with us, have fluctuated. When destruction 
rates for records stored with us increase, it has a positive impact on our service revenues in the year of destruction but negatively 
impacts our longer term storage revenues, adversely affecting our financial condition and results of operations.

We and our customers are subject to laws and governmental regulations relating to data privacy and cybersecurity and our 
customers’ demands in this area are increasing. This may cause us to incur significant expenses and non-compliance with such 
regulations and demands could harm our business.

We are subject to numerous U.S. federal, state, local and foreign laws and regulations relating to data privacy and cybersecurity. 
These regulations are complex, change frequently and have tended to become more stringent over time. There are also a number 
of legislative proposals pending before the U.S. Congress, various state legislative bodies and foreign governments concerning 
data protection that could affect us. In addition, a growing number of U.S. and foreign legislative and regulatory bodies have 
adopted consumer notification and other requirements if consumer information is accessed by unauthorized persons and additional 
regulations regarding the use, access, accuracy and security of such information are possible. In the U.S., we are subject to 
various state laws which provide for disparate notification regimes. In addition, as a result of the continued emphasis on information 
security and instances in which personal information has been compromised, our customers are requesting that we take 
increasingly sophisticated measures to enhance security and comply with data privacy regulations, and that we assume higher 
liability under our contracts. 

We devote substantial resources, and may in the future have to devote significant additional resources, to facilitate compliance with 
laws and regulations, our customers’ data privacy and security demands, and to investigate, defend or remedy actual or alleged 
violations or breaches. Any failure by us to comply with, or remedy any violations or breaches of, laws and regulations or customer 
requirements could result in the curtailment of certain of our operations, the imposition of fines and penalties, liability resulting from 
litigation, restrictions on our ability to carry on or expand our operations, significant costs and expenses and reputational harm.

Attacks on our internal IT systems could damage our reputation, cause us to lose revenues, and adversely affect our business, 
financial condition and results of operations.

Our reputation for providing secure information storage to customers is critical to the success of our business. Our reputation or 
brand, and specifically, the trust our customers place in us, could be negatively impacted in the event of perceived or actual failures 
by us to store information securely. Although we seek to prevent and detect attempts by unauthorized users to gain access to our 
IT systems, and incur significant costs to do so, our IT and network infrastructure has in the past been and may in the future be 
vulnerable to attacks by hackers, including state-sponsored organizations with significant financial and technological resources, 
breaches due to employee error, fraud or malice or other disruptions (including, but not limited to, computer viruses and other 
malware, denial of service, and ransomware), which may involve a privacy breach requiring us to notify regulators, clients or 
employees and enlist identity theft protection. Moreover, until we have migrated businesses we acquire onto our IT systems or 
ensured compliance with our information technology security standards, we have in the past and may in the future face additional 
risks because of the continued use of predecessor IT systems. We have outsourced, and expect to continue to outsource, certain 
support services, including cloud storage systems and cloud computing services, to third parties, which has in the past and may in 
the future subject our IT and other sensitive information to additional risk. In addition, the continuation of remote work 
arrangements as a result of the COVID-19 pandemic has increased and could further increase our cybersecurity risks. A successful 
breach of the security of our IT systems could lead to theft or misuse of our customers’ proprietary or confidential information or our 
employees’ personal information and result in third party claims against us, regulatory penalties, and reputational harm. Although 
we maintain insurance coverage for various cybersecurity risks, there is no guarantee that all costs or losses incurred will be fully 
insured. Damage to our reputation could make us less competitive, which could negatively impact our business, financial condition 
and results of operations.

Our business, operations, and financial results have been, and could continue to be, impacted by developments in the COVID-19 
pandemic.

The COVID-19 pandemic, and the ongoing emergence of variants of the SARS-CoV-2 virus, and the resulting actions taken in 
response by governments, businesses, and individuals have resulted in, and are expected to continue to result in, substantial  
increased cyclical impacts to the global economy, including a curtailment of business activities (including changes in demand for a 
broad variety of goods and services), weakened economic conditions, disruptions in supply, manufacturing and logistics, economic 
uncertainty and volatility in the financial markets, both in the United States and abroad, as well as reduced service operations and 
changed business practices for us, our customers, and other third parties with which we do business. 

Due to the unpredictable and rapidly changing nature of the COVID-19 pandemic, the extent to which it continues to impact us will 
depend on numerous factors that we are unable to predict and are not within our control, including: the duration or re-emergence of 
outbreaks and developments of variants of the SARS-CoV-2 virus, the distribution, public acceptance and efficacy of COVID-19 
vaccines; the continuation, resumption, and/or expansion of restrictions imposed by governments and businesses; the impact of 
any resulting inflationary or recessionary conditions and general economic uncertainty in the global markets; the pace of economic 
recovery from any impact of the COVID-19 pandemic; and the impact of any such factors on our customers, suppliers, vendors, 
and other business partners.

Complying with fire and safety standards may result in significant expense.

As of December 31, 2021, we operated approximately 1,450 facilities worldwide, including more than 600 in the United States. 
Many of these facilities were built and outfitted by third parties and added to our real estate portfolio as part of acquisitions. Some 
of these facilities contain fire suppression and safety features that are different from our current specifications and current 
standards for new facilities, although we believe these facilities were in compliance with applicable fire and safety laws and 
regulations in effect at the time of their construction or outfitting. In some instances, local authorities may take the position that our 
fire suppression and safety features in a particular facility are insufficient and require additional measures that may involve 
considerable expense to us. In addition, where we determine that the fire suppression and safety features of a facility require 
improvement, we will develop and implement a plan to remediate the issue, although implementation may require an extended 
period to complete. A significant aspect of the integration of businesses we have acquired or may acquire is the process of making 
investments in the acquired facilities to conform such facilities to our standards of operations. This process is complex and time-
consuming. If additional fire safety and suppression measures beyond our current operating plan were required at a large number 
of our facilities, the expense required for compliance could negatively impact our business, financial condition or results of 
operations.

If we fail to meet our commitment to transition to more renewable and sustainable sources of energy, it may negatively impact our 
ability to attract and retain customers, employees and investors who focus on this commitment. Furthermore, changes to 
environmental laws and standards may increase the cost to operate some of our businesses. This could impact our results of 
operations and the trading of our stock.

We have made a commitment to prioritize sustainable energy practices, reduce our carbon footprint and transition to more 
renewable and sustainable sources of energy, particularly in our data center business. We have made progress towards reducing 
our carbon footprint, but if we are not successful in continuing this reduction or if our customers, employees and investors are not 
satisfied with our sustainability efforts, it may negatively impact our ability to attract and retain customers, employees and investors 
who focus on this commitment. This could negatively impact our results of operations and the trading of our stock.

IRON MOUNTAIN 2021 FORM 10-K

Part I

Furthermore, changes in environmental laws in any jurisdiction in which we operate could increase compliance costs or impose 
limitations on our operations. For example, our emergency generators at our data centers are subject to regulations and permit 
requirements governing air pollutants, and the heating, ventilation and air conditioning and fire suppression systems at some of our 
data centers and data management locations may include ozone-depleting substances that are subject to regulation. While 
environmental regulations do not normally impose material costs upon operations at our facilities, unexpected events, equipment 
malfunctions, human error and changes in law or regulations, among other factors, could result in unexpected costs, which could 
be material.

Failure to successfully integrate acquired businesses could negatively impact our balance sheet and results of operations.

Strategic acquisitions are an important element of our growth strategy and the success of any acquisition we make depends in part 
on our ability to integrate the acquired business and realize anticipated synergies. The process of integrating acquired businesses, 
particularly in new markets or for new offerings, may involve unforeseen difficulties and may require a disproportionate amount of 
our management’s attention and our financial and other resources.

For example, the success of our significant acquisitions depends, in large part, on our ability to realize the anticipated benefits, 
including cost savings or revenue acceleration from combining the acquired businesses with ours. To realize these anticipated 
benefits, we must be able to successfully integrate our business and the acquired businesses, and this integration is complex and 
time-consuming. We may encounter challenges in the integration process including the following:

• challenges and difficulties associated with managing our larger, more complex, company;

• conforming standards, controls, procedures and policies, business cultures and compensation and benefits structures between 

the two businesses;

• consolidating corporate and administrative infrastructures;

• coordinating geographically dispersed organizations;

•

retaining critical acquired talent;

• potential unknown liabilities and unforeseen expenses or delays associated with an acquisition; and

• our ability to deliver on our strategy going forward.

Further, our acquisitions subject us to liabilities (including tax liabilities) that may exist at an acquired company, some of which may 
be unknown. Although we and our advisors conduct due diligence on the businesses we acquire, there can be no guarantee that 
we are aware of all liabilities of an acquired company. These liabilities, and any additional risks and uncertainties related to an 
acquired company not known to us or that we may deem immaterial or unlikely to occur at the time of the acquisition, could 
negatively impact our future business, financial condition and results of operations.

We can give no assurance that we will ultimately be able to effectively integrate and manage the operations of any acquired 
business or realize anticipated synergies. The failure to successfully integrate the cultures, operating systems, procedures and 
information technologies of an acquired business could have a material adverse effect on our financial condition and results of 
operations.

Our customer contracts may not always limit our liability and may sometimes contain terms that could lead to disputes in contract 
interpretation.

Our customer contracts typically contain standardized provisions limiting our liability regarding the services we perform and the loss 
or destruction of, or damage to, records, information, or other items stored with us; however, some of our contracts with large 
customers and some of the contracts assumed in our acquisitions contain no such limits or contain non-standard limits. We can 
provide no assurance that our limitation of liability provisions will be enforceable in all instances or, if enforceable, that they would 
otherwise protect us from liability. In the past, we have had relatively few disputes with our customers regarding the terms of their 
customer contracts, and most disputes to date have not been material, but we can provide no assurance that we will not have 
material disputes in the future. Moreover, as we expand our operations in digital solutions and the storage of valuable items and 
respond to customer demands for higher limitation of liability, our exposure to contracts with higher or no limitations of liability and 
disputes with customers over contract interpretation may increase. Although we maintain a comprehensive insurance program, we 
can provide no assurance that we will be able to maintain insurance policies on acceptable terms or with high enough coverage 
amounts to cover losses to us in connection with customer contract disputes.

International operations pose unique risks.

As of December 31, 2021, we operated in over 60 countries outside the United States. Our international operations account for a 
significant portion of our overall operations, and as part of our growth strategy, we expect its share to increase as we continue to 
acquire or invest in businesses in select foreign markets, including countries where we do not currently operate. International 
operations are subject to numerous risks, including:

•

the impact of foreign government and United States laws and regulations that apply to us in foreign countries where we operate; 
in particular, we are subject to United States and foreign sanctions and anti-corruption laws, such as the Foreign Corrupt 
Practices Act and the United Kingdom Bribery Act, and, although we have implemented internal controls, policies and 
procedures and training to deter prohibited practices, our employees, partners, contractors or agents may violate or circumvent 
such policies and the law; 

• costs and difficulties associated with managing international operations including cross border sales;

•

•

the volatility of certain foreign economies in which we operate;

fluctuations of foreign currency exchange rates in the markets in which we operate;

• political uncertainties and changes in the global political climate or other global events, such as trade wars involving the U.S. or 
global pandemics, including the COVID-19 pandemic, which may impose restrictions on, or create additional risk in relation to, 
global operations, which risks may become more pronounced as we consolidate operations across countries and need to move 
records and data across borders; 

•

the risk that business partners upon whom we depend for technical assistance or management and acquisition expertise in 
some markets outside of the United States will not perform as expected;

• difficulties attracting and retaining local management and key employees to operate our business in certain countries; and

• cultural differences and differences in business practices and operating standards, as well as risks and challenges in expanding 

into countries where we have no prior operational experience.

Our use of joint ventures could expose us to additional risks and liabilities, including our reliance on joint venture partners who may 
have economic and business interests that are inconsistent with our business interests, our lack of sole decision-making authority, 
and disputes between us and our joint venture partners.

As part of our growth strategy, particularly in connection with our international and data center expansion, we currently, and may in 
the future, co-invest with third parties using joint ventures. These joint ventures can result in our holding non-controlling interests in, 
or having shared responsibility for managing the affairs of, a property or portfolio of properties, business, partnership, joint venture 
or other entity. As a result, in connection with our pursuit or entrance into any such joint venture, we may be subject to additional 
risks, including:

• our ability to sell our interests in the joint venture may be limited by the joint venture agreement;  

• we may not have the right to exercise sole decision-making authority regarding the properties, business, partnership, joint 

venture or other entity;

•

if our partners become bankrupt or fail to fund their share of required capital contributions, we may choose or be required to 
contribute unplanned capital;

• our partners may have economic, tax or other interests or goals that are inconsistent with our interests or goals, and that could 

affect our ability to negotiate satisfactory joint venture terms, to operate the property or business or maintain our qualification for 
taxation as a REIT;

• our partners may be subject to different laws or regulations than us, or may be structured differently than us for tax purposes, 

which could create conflicts of interest and/or affect our ability to maintain our qualification for taxation as a REIT;

• our partners may take actions that are not within our control, which could require us to dispose of the joint venture asset, transfer 

it to a taxable REIT subsidiary (“TRS”) in order for us to maintain our qualification for taxation as a REIT, or purchase such 
partner’s interests or assets at an above-market price;

• we may agree to restrictions on our ability to expand our business in certain geographies independently or with other partners;

• disputes between us and our partners may result in litigation or arbitration that would increase our expenses and prevent our 

management from focusing their time and effort on our day-to-day business; and

• we may in certain circumstances be liable for the actions of our third-party partners or guarantee all or a portion of the joint 

venture’s liabilities, which may require us to pay an amount greater than our investment in the joint venture.

Each of these factors may result in returns on these investments being less than we expect or in losses, and our financial and 
operating results may be adversely affected.

Part I

Significant costs or disruptions at our data centers could adversely affect our business, financial condition and results of operations.

Our Global Data Center Business depends on providing customers with highly reliable facilities, power infrastructure and 
operations solutions, and we will need to retain and hire qualified personnel to manage our data centers. Service interruptions or 
significant equipment damage could result in difficulty maintaining service level commitment obligations that we owe to certain of 
our customers. Service interruptions or equipment damage may occur at one or more of our data centers because of numerous 
factors, including: human error; equipment failure; physical, electronic and cyber security breaches; fire, hurricane, flood, 
earthquake and other natural disasters; water damage; fiber cuts; extreme temperatures; power loss or telecommunications failure; 
war, terrorism and any related conflicts or similar events worldwide; and sabotage and vandalism. We also purchase significant 
amounts of electricity from generating facilities and utility companies that are subject to environmental laws, regulations and permit 
requirements. These environmental requirements are subject to material change, which could result in increases in our electricity 
suppliers’ compliance costs that may be passed through to us. In addition, climate change may increase the likelihood that our data 
centers are affected by some of these factors.

While these risks could impact our overall business, they could have a more significant impact on our Global Data Center 
Business, where we have service level commitment obligations to certain of our customers. As a result, service interruptions or 
significant equipment damage at our data centers could result in difficulty maintaining service level commitments to these 
customers and potential claims related to such failures. Because our data centers are critical to many of our customers’ 
businesses, service interruptions or significant equipment damage at our data centers could also result in lost profits or other 
indirect or consequential damages to our customers.

Our Global Data Center Business is susceptible to regional costs of power, power shortages, planned or unplanned power outages 
and limitations on the availability of adequate power resources. We rely on third parties to provide power to our data centers. We 
are therefore subject to an inherent risk that such third parties may fail to deliver such power in adequate quantities or on a 
consistent basis. If the power delivered to our data centers is insufficient or interrupted, we would be required to provide power 
through the operation of our on-site generators, generally at a significantly higher operating cost. Additionally, global fluctuations in 
the price of power can increase the cost of energy, and we may be limited in our ability to, or may not always choose to, pass these 
increased costs on to our customers. We also rely on third party telecommunications carriers to provide internet connectivity to our 
customers. These carriers may elect not to offer or to restrict their services within our data centers or may elect to discontinue such 
services. Furthermore, carriers may face business difficulties, which could affect their ability to provide telecommunications 
services or the quality of such services. If connectivity is interrupted or terminated, our financial condition and results of operations 
may be adversely affected. Events such as these may also impact our reputation as a data center provider which could adversely 
affect our results of operations.

We face additional risks in expanding our Global Data Center Business, including the significant amount of capital required.

Expanding our Global Data Center Business requires significant capital commitments. In addition, we may be required to commit 
significant operational and financial resources in connection with the organic growth of our Global Data Center Business, generally 
12 to 18 months in advance of securing customer contracts, and we may not have enough customer demand to support these data 
centers when they are built. There can be no assurance we will have sufficient customer demand to support the data centers we 
have acquired, or that we will not be adversely affected by the risks noted above under "Significant costs or disruptions at our data 
centers could adversely affect our business, financial condition and results of operations", which could make it difficult for us to 
realize expected returns on our investments, if any.  

Failure to comply with certain regulatory and contractual requirements under our United States Government contracts could 
adversely affect our revenues, operating results and financial position and reputation.

Having the United States Government as a customer subjects us to certain regulatory and contractual requirements. Failure to 
comply with these requirements could subject us to investigations, price reductions, up to treble damages, and civil penalties. 
Noncompliance with certain regulatory and contractual requirements could also result in us being suspended or debarred from 
future United States Government contracting. We may also face private derivative securities claims because of adverse 
government actions. Any of these outcomes could have a material adverse effect on our revenues, operating results, financial 
position and reputation.

We may be subject to certain costs and potential liabilities associated with the real estate required for our business.

Because our business is heavily dependent on real estate, we face special risks attributable to the real estate we own or lease. 
Such risks include:

• acquisition and occupancy costs that make it difficult to meet anticipated margins and difficulty locating suitable facilities due to a 

relatively small number of available buildings having the desired characteristics in some real estate markets; 

•

increases in rent expense and property tax as a result of the increasing demand for industrial real estate;

• uninsured losses or damage to our storage facilities due to an inability to obtain full coverage on a cost-effective basis for some 
casualties, such as fires, hurricanes and earthquakes, or any coverage for certain losses, such as losses from riots or terrorist 
activities;

•

•

inability to use our real estate holdings effectively and costs associated with vacating or consolidating facilities if the demand for 
physical storage were to diminish; and

liability under environmental laws for the costs of investigation and cleanup of contaminated real estate owned or leased by us, 
whether or not (i) we know of, or were responsible for, the contamination, or (ii) the contamination occurred while we owned or 
leased the property.

Some of our current and formerly owned or leased properties were previously used by entities other than us for industrial or other 
purposes, or were affected by waste generated from nearby properties, that involved the use, storage, generation and/or disposal 
of hazardous substances and wastes, including petroleum products. In some instances this prior use involved the operation of 
underground storage tanks or the presence of asbestos-containing materials. Where we are aware of environmental conditions that 
require remediation, we undertake appropriate activity, in accordance with all legal requirements. Although we have from time to 
time conducted limited environmental investigations and remedial activities at some of our former and current facilities, we have not 
undertaken an environmental review of all of our properties, including those we have acquired. We therefore may be potentially 
liable for environmental costs like those discussed above and may be unable to sell, rent, mortgage or use contaminated real 
estate owned or leased by us. Environmental conditions for which we might be liable may also exist at properties that we may 
acquire in the future. In addition, future regulatory action and environmental laws may impose costs for environmental compliance 
that do not exist today.

Unexpected events, including those resulting from climate change or geopolitical events, could disrupt our operations and 
adversely affect our reputation and results of operations.

Unexpected events, including fires or explosions at our facilities, war or other military conflict, including an escalation of the conflict 
between Russia and Ukraine, or terrorist activities, natural disasters such as earthquakes and wildfires, unplanned power outages, 
supply disruptions, failure of equipment or systems, and severe weather events, such as droughts, heat waves, hurricanes, and 
flooding, could adversely affect our reputation and results of operations through physical damage to our facilities and equipment 
and through physical damage to, or disruption of, local infrastructure. During the past several years we have seen an increase in 
the frequency and intensity of severe weather events and we expect this trend to continue due to climate change. Some of our key 
facilities worldwide are vulnerable to severe weather events, and global weather pattern changes may also pose long-term risks of 
physical impacts to our business. Our customers rely on us to securely store and timely retrieve their critical information, and, while 
we maintain disaster recovery and business continuity plans that would be implemented in these situations, these unexpected 
events could result in customer service disruption, physical damage to one or more key operating facilities and the information 
stored in those facilities, the temporary closure of one or more key operating facilities or the temporary disruption of information 
systems, each of which could negatively impact our reputation and results of operations. In addition, these unexpected events 
could negatively impact our reputation if such events result in adverse publicity, governmental investigations or litigation or if 
customers do not otherwise perceive our response to be adequate. 

Fluctuations in commodity prices may affect our operating revenues and results of operations.

Our operating revenues and results of operations are impacted by significant changes in commodity prices. In particular, our secure 
shredding operations generate revenue from the sale of shredded paper for recycling. Further, significant declines in the cost of 
paper may continue to negatively impact our revenues and results of operations, and increases in other commodity prices, 
including steel, may negatively impact our results of operations.

Failure to manage and adequately implement our new IT systems could negatively affect our business.

We rely on IT infrastructure, including hardware, networks, software, people and processes, to provide information to support 
assessments and conclusions about our operating performance. We are in the process of upgrading a number of our IT systems, 
including consolidating our existing finance operations platforms, and we face risks relating to these transitions. For example, we 
may incur greater costs than we anticipate training our personnel on the new systems, we may experience service disruptions or 
errors in accurately capturing data or retaining our records, and we may be delayed in meeting our various reporting obligations. 
There can be no assurance that we will manage our IT systems and implement these new systems as planned or that we will do so 
without disruptions to our operations, which could have an adverse effect on our business, financial condition, results of operations 
and cash flows.

RISKS RELATED TO OUR INDEBTEDNESS

Our substantial indebtedness could adversely affect our financial health and prevent us from fulfilling our obligations under our 
various debt instruments.

We have a significant amount of indebtedness. As of December 31, 2021, our total long-term debt was approximately $9.3 billion, 
stockholders equity was approximately $856 million and we had cash and cash equivalents (including restricted cash) of 
approximately $256 million. Our substantial indebtedness could have important consequences to our current and potential 
investors. These risks include:

•

•

•

•

•

•

•

•

inability to satisfy our obligations with respect to our various debt instruments;

inability to make borrowings to fund future working capital, capital expenditures and strategic growth opportunities, including 
acquisitions, further organic development of our Global Data Center Business and expansions into adjacent businesses and 
other service offerings, and other general corporate requirements, including possible required repurchases, redemptions or 
prepayments of our various indebtedness;

limits on our distributions to stockholders; in this regard if these limits prevented us from satisfying our REIT distribution 
requirements, we could fail to remain qualified for taxation as a REIT or, if these limits do not jeopardize our qualification for 
taxation as a REIT but do nevertheless prevent us from distributing 100% of our REIT taxable income, we will be subject to 
federal corporate income tax, and potentially a nondeductible excise tax, on the retained amounts;

limits on future borrowings under our existing or future credit arrangements, which could affect our ability to pay our 
indebtedness or to fund our other liquidity needs;

inability to generate sufficient funds to cover required interest payments;

restrictions on our ability to refinance our indebtedness on commercially reasonable terms;

limits on our flexibility in planning for, or reacting to, changes in our business and the information management services industry; 
and

inability to adjust to adverse economic conditions that could place us at a disadvantage to our competitors with less debt and 
who, therefore, may be able to take advantage of opportunities that our indebtedness prevents us from pursuing.

Despite our current indebtedness levels, we may still incur substantially more debt, particularly in order to execute on our strategic 
growth plan. The terms of our indentures generally do not cap the maximum amount of additional funds that may be borrowed 
under our Credit Agreement and possible future credit arrangements. 

Restrictive debt covenants may limit our ability to pursue our growth strategy.

Our Credit Agreement and our indentures contain covenants restricting or limiting our ability to, among other things:

•

incur additional indebtedness;

• pay dividends or make other restricted payments;

• make asset dispositions;

• create or permit liens;

• sell, transfer or exchange assets;

• guarantee certain indebtedness;

• make acquisitions and other investments; and

• enter into partnerships and joint ventures.

These restrictions and our long-term commitment to reduce our leverage ratio may adversely affect our ability to pursue our 
acquisition and other growth strategies, including our strategic growth plan.

We may not have the ability to raise the funds necessary to finance the repurchase of outstanding senior notes upon a change of 
control event as required by our indentures.

Upon the occurrence of a “change of control,” as defined in our indentures, we will be required to offer to repurchase all of our 
outstanding senior notes. However, it is possible that we will not have sufficient funds at the time of a change of control to make the 
required repurchase of any outstanding notes or that restrictions in our Credit Agreement will not allow such repurchases. Certain 
important corporate events, however, such as leveraged recapitalizations that would increase the level of our indebtedness, would 
not constitute a “change of control” under our indentures.

Iron Mountain Incorporated (“IMI”) is a holding company, and, therefore, its ability to make payments on its various debt obligations 
depends in large part on the operations of its subsidiaries.

IMI is a holding company; substantially all of its assets consist of the equity in its subsidiaries, and substantially all of its operations 
are conducted by its direct and indirect consolidated subsidiaries. As a result, its ability to make payments on its debt obligations 
will be dependent upon the receipt of sufficient funds from its subsidiaries, whose ability to distribute funds may be limited by local 
capital requirements, joint venture structures and other applicable restrictions. However, our various debt obligations are 
guaranteed, on a joint and several and full and unconditional basis, by IMI’s U.S. subsidiaries that represent the substantial 
majority of its U.S. operations.

RISKS RELATED TO OUR TAXATION AS A REIT

If we fail to remain qualified for taxation as a REIT, we will be subject to tax at corporate income tax rates and will not be able to 
deduct distributions to stockholders when computing our taxable income.

We have elected to be taxed as a REIT for federal income tax purposes beginning with our 2014 taxable year. We believe that our 
organization and method of operation comply with the rules and regulations promulgated under the Internal Revenue Code of 
1986, as amended (the “Code”), such that we will continue to qualify for taxation as a REIT. However, we can provide no assurance 
that we will remain qualified for taxation as a REIT. If we fail to remain qualified for taxation as a REIT, we will be subject to federal 
income taxation at corporate income tax rates unless certain relief provisions apply.

Qualification for taxation as a REIT involves the application of highly technical and complex provisions of the Code to our 
operations as well as various factual determinations concerning matters and circumstances not entirely within our control. There 
are limited judicial or administrative interpretations of applicable REIT provisions of the Code.

If, in any taxable year, we fail to remain qualified for taxation as a REIT and are not entitled to relief under the Code:

• we will not be allowed a deduction for distributions to stockholders in computing our taxable income;

• we will be subject to federal and state income tax on our taxable income at regular corporate income tax rates; and

• we would not be eligible to elect REIT status again until the fifth taxable year that begins after the first year for which we failed to 

qualify for taxation as a REIT.

Any such corporate tax liability could be substantial and would reduce the amount of cash available for other purposes. If we fail to 
remain qualified for taxation as a REIT, we may need to borrow additional funds or liquidate some investments to pay any 
additional tax liability. Accordingly, funds available for investment and distributions to stockholders could be reduced.

As a REIT, failure to make required distributions would subject us to federal corporate income tax.

We expect to continue paying regular quarterly distributions; however, the amount, timing and form of our regular quarterly 
distributions will be determined, and will be subject to adjustment, by our board of directors. To remain qualified for taxation as a 
REIT, we are generally required to distribute at least 90% of our REIT taxable income (determined without regard to the dividends 
paid deduction and excluding net capital gain) each year, or in limited circumstances, the following year, to our stockholders. 
Generally, we expect to distribute all or substantially all of our REIT taxable income. If our cash available for distribution falls short 
of our estimates, we may be unable to maintain distributions that approximate our REIT taxable income and may fail to remain 
qualified for taxation as a REIT. In addition, our cash flows from operations may be insufficient to fund required distributions as a 
result of differences in timing between the actual receipt of income and the payment of expenses and the recognition of income and 
expenses for federal income tax purposes, or the effect of nondeductible expenditures.

To the extent that we satisfy the 90% distribution requirement but distribute less than 100% of our REIT taxable income, we will be 
subject to federal corporate income tax on our undistributed taxable income. In addition, we will be subject to a 4% nondeductible 
excise tax on our undistributed taxable income if the actual amount that we distribute to our stockholders for a calendar year is less 
than the minimum amount specified under the Code.

We may be required to borrow funds, sell assets or raise equity to satisfy our REIT distribution requirements, to comply with asset 
ownership tests or to fund capital expenditures, future growth and expansion initiatives.

In order to satisfy our REIT distribution requirements and maintain our qualification and taxation as a REIT, or to fund capital 
expenditures, future growth and expansion initiatives, we may need to borrow funds, sell assets or raise equity, even if our financial 
condition or the then-prevailing market conditions are not favorable for these borrowings, sales or offerings. Furthermore, the REIT 
distribution requirements and our commitment to investors on dividend growth may result in increasing our financing needs to fund 
capital expenditures, future growth and expansion initiatives, which would increase our indebtedness. An increase in our 
outstanding debt could lead to a downgrade of our credit ratings, which could negatively impact our ability to access credit markets. 
Further, certain of our current debt instruments limit the amount of indebtedness we and our subsidiaries may incur. Additional 
financing, therefore, may be unavailable, more expensive or restricted by the terms of our outstanding indebtedness. For a 
discussion of risks related to our substantial level of indebtedness, see “Risks Related to Our Indebtedness.”

Part I

Complying with REIT requirements may limit our flexibility, cause us to forgo otherwise attractive opportunities that we would 
otherwise pursue to execute our strategic growth plan, or otherwise reduce our income and amounts available for distribution to our 
stockholders.

To remain qualified for taxation as a REIT, we must satisfy tests concerning, among other things, the sources of our income, the 
nature and diversification of our assets and the amounts we distribute to our stockholders. Thus, compliance with these tests may 
require us to refrain from certain activities and may hinder our ability to make certain attractive investments, including the purchase 
of non-REIT qualifying operations or assets, the expansion of non-real estate activities, and investments in the businesses to be 
conducted by our TRSs, and, to that extent, limit our opportunities and our flexibility to change our business strategy and execute 
on our strategic growth plan. This may restrict our ability to acquire certain businesses, enter into joint ventures or acquire minority 
interests of companies. Furthermore, acquisition opportunities in domestic and international markets may be adversely affected if 
we need or require the target company to comply with some REIT requirements prior to closing.

We conduct a significant portion of our business activities, including our information management services businesses and several 
of our international operations, through domestic and foreign TRSs. Under the Code, no more than 20% of the value of the assets 
of a REIT may be represented by securities of one or more TRSs. Similar rules apply to other nonqualifying assets. These 
limitations may affect our ability to make additional investments in non-REIT qualifying operations or assets or in international 
operations through TRSs.

If we fail to comply with specified asset ownership tests applicable to REITs as measured at the end of any calendar quarter, we 
generally must correct such failure within 30 days after the end of the applicable calendar quarter or qualify for statutory relief 
provisions to avoid losing our qualification for taxation as a REIT. As a result, we may be required to liquidate assets or to forgo our 
pursuit of otherwise attractive investments or executing on portions of our strategic growth plan. These actions may reduce our 
income and amounts available for distribution to our stockholders.

As a REIT, we are limited in our ability to fund distribution payments using cash generated through our TRSs.

Our ability to receive distributions from our TRSs is limited by the rules with which we must comply to maintain our qualification for 
taxation as a REIT. In particular, at least 75% of our gross income for each taxable year as a REIT must be derived from real 
estate, which generally includes gross income from providing customers with secure storage space or colocation or wholesale data 
center space. Consequently, no more than 25% of our gross income may consist of dividend income from our TRSs and other 
nonqualifying types of income. Thus, our ability to receive distributions from our TRSs may be limited, which may impact our ability 
to fund distributions to our stockholders using cash flows from our TRSs. Specifically, if our TRSs become highly profitable, we 
might become limited in our ability to receive net income from our TRSs in an amount required to fund distributions to our 
stockholders commensurate with that profitability.

In addition, a significant amount of our income and cash flows from our TRSs is generated from our international operations. In 
many cases, there are local withholding taxes and currency controls that may impact our ability or willingness to repatriate funds to 
the United States to help satisfy REIT distribution requirements.

Our extensive use of TRSs, including for certain of our international operations, may cause us to fail to remain qualified for taxation 
as a REIT.

Our operations include an extensive use of TRSs. The net income of our TRSs is not required to be distributed to us, and income 
that is not distributed to us generally is not subject to the REIT income distribution requirement. However, there may be limitations 
on our ability to accumulate earnings in our TRSs and the accumulation or reinvestment of significant earnings in our TRSs could 
result in adverse tax treatment. In particular, if the accumulation of cash in our TRSs causes (1) the fair market value of our 
securities in our TRSs to exceed 20% of the fair market value of our assets or (2) the fair market value of our securities in our TRSs 
and other nonqualifying assets to exceed 25% of the fair market value of our assets, then we will fail to remain qualified for taxation 
as a REIT. Further, a substantial portion of our operations are conducted overseas, and a material change in foreign currency rates 
could also affect the value of our foreign holdings in our TRSs, negatively impacting our ability to remain qualified for taxation as a 
REIT.

Even if we remain qualified for taxation as a REIT, some of our business activities are subject to corporate level income tax and 
foreign taxes, which will continue to reduce our cash flows, and we will have potential deferred and contingent tax liabilities.

Even if we remain qualified for taxation as a REIT, we may be subject to some federal, state, local and foreign taxes, including 
taxes on any undistributed income, and state, local or foreign income, franchise, property and transfer taxes. In addition, we could 
in certain circumstances be required to pay an excise or penalty tax, which could be significant in amount, in order to utilize one or 
more relief provisions under the Code to maintain our qualification for taxation as a REIT.

A portion of our business is conducted through wholly-owned TRSs because certain of our business activities could generate 
nonqualifying REIT income as currently structured and operated. The income of our domestic TRSs will continue to be subject to 
federal and state corporate income taxes. In addition, our international assets and operations will continue to be subject to taxation 
in the foreign jurisdictions where those assets are held or those operations are conducted. Any of these taxes would decrease our 
earnings and our available cash.

                                                                                                                                                                                                                                  Part I

We will also be subject to a federal corporate level income tax at the highest regular corporate income tax rate on gain recognized 
from a sale of a REIT asset where our basis in the asset is determined by reference to the basis of the asset in the hands of a C 
corporation (such as an asset that we hold in one of our qualified REIT subsidiaries (“QRSs”) following the liquidation or other 
conversion of a former TRS). This tax is generally applicable to any disposition of such an asset during the five-year period after 
the date we first owned the asset as a REIT asset, to the extent of the built-in-gain based on the fair market value of such asset on 
the date we first held the asset as a REIT asset. In addition, any depreciation recapture income that we recognize because of 
accounting method changes that we make in connection with our acquisition activities will be fully subject to this tax.

Complying with REIT requirements may limit our ability to hedge effectively and increase the cost of our hedging and may cause us 
to incur tax liabilities.

The REIT provisions of the Code limit our ability to hedge assets, liabilities, revenues and expenses. Generally, income from 
hedging transactions that we enter into to manage risk of interest rate changes with respect to borrowings made or to be made by 
us to acquire or carry real estate assets and income from certain currency hedging transactions related to our non-United States 
operations, as well as income from qualifying counteracting hedges, do not constitute “gross income” for purposes of the REIT 
gross income tests. To the extent that we enter into other types of hedging transactions, the income from those transactions is likely 
to be treated as nonqualifying income for purposes of the REIT gross income tests. As a result of these rules, we may need to limit 
our use of advantageous hedging techniques or implement those hedges through our TRSs. This could increase the cost of our 
hedging activities because our TRSs would be subject to tax on income or gains resulting from hedges entered into by them and 
may expose us to greater risks associated with changes in interest rates or exchange rates than we would otherwise want to bear. 
In addition, hedging losses in any of our TRSs generally will not provide any tax benefit, except for being carried forward for 
possible use against future income or gain in the TRSs.

Distributions payable by REITs generally do not qualify for preferential tax rates.

Dividends payable by United States corporations to noncorporate stockholders, such as individuals, trusts and estates, are 
generally eligible for reduced United States federal income tax rates applicable to “qualified dividends.” Distributions paid by REITs 
generally are not treated as “qualified dividends” under the Code, and the reduced rates applicable to such dividends do not 
generally apply. However, for tax years beginning before 2026, REIT dividends paid to noncorporate stockholders that meet 
specified holding period requirements are generally taxed at an effective tax rate lower than applicable ordinary income tax rates 
due to the availability of a deduction under the Code for specified forms of income from passthrough entities. More favorable rates 
will nevertheless continue to apply to regular corporate “qualified” dividends, which may cause some investors to perceive that an 
investment in a REIT is less attractive than an investment in a non-REIT entity that pays dividends, thereby reducing the demand 
and market price of our common stock.

The ownership and transfer restrictions contained in our certificate of incorporation may not protect our qualification for taxation as 
a REIT, could have unintended antitakeover effects and may prevent our stockholders from receiving a takeover premium.

In order for us to remain qualified for taxation as a REIT, no more than 50% of the value of outstanding shares of our capital stock 
may be owned, beneficially or constructively, by five or fewer individuals at any time during the last half of each taxable year. In 
addition, rents from “affiliated tenants” will not qualify as qualifying REIT income if we own 10% or more by vote or value of the 
customer, whether directly or after application of attribution rules under the Code. Subject to certain exceptions, our certificate of 
incorporation prohibits any stockholder from owning, beneficially or constructively, more than (i) 9.8% in value of the outstanding 
shares of all classes or series of our capital stock or (ii) 9.8% in value or number, whichever is more restrictive, of the outstanding 
shares of any class or series of our capital stock. We refer to these restrictions collectively as the “ownership limits” and we 
included them in our certificate of incorporation to facilitate our compliance with REIT tax rules. The constructive ownership rules 
under the Code are complex and may cause the outstanding stock owned by a group of related individuals or entities to be deemed 
to be constructively owned by one individual or entity. As a result, the acquisition of less than 9.8% of our outstanding common 
stock (or the outstanding shares of any class or series of our capital stock) by an individual or entity could cause that individual or 
entity or another individual or entity to own constructively in excess of the relevant ownership limits. Any attempt to own or transfer 
shares of our common stock or of any of our other capital stock in violation of these restrictions may result in the shares being 
automatically transferred to a charitable trust or may be void. Even though our certificate of incorporation contains the ownership 
limits, there can be no assurance that these provisions will be effective to prevent our qualification for taxation as a REIT from 
being jeopardized, including under the affiliated tenant rule. Furthermore, there can be no assurance that we will be able to monitor 
and enforce the ownership limits. If the restrictions in our certificate of incorporation are not effective and, as a result, we fail to 
satisfy the REIT tax rules described above, then, absent an applicable relief provision, we will fail to remain qualified for taxation as 
a REIT.

In addition, the ownership and transfer restrictions could delay, defer or prevent a transaction or a change in control that might 
involve a premium price for our stock or otherwise be in the best interest of our stockholders. As a result, the overall effect of the 
ownership and transfer restrictions may be to render more difficult or discourage any attempt to acquire us, even if such acquisition 
may be favorable to the interests of our stockholders.

Part I

Legislative or other actions affecting REITs could have a negative effect on us or our stockholders.

At any time, the federal or state income tax laws governing REITs, the administrative interpretations of those laws, or local laws 
impacting our REIT structure for our international operations may be amended. Federal, state and local tax laws are constantly 
under review by persons involved in the legislative process, the IRS, the United States Department of the Treasury (“Treasury”) and 
state and local taxing authorities. Changes to the tax laws, regulations and administrative interpretations or local laws governing 
our international operations, which may have retroactive application, could adversely affect us. In addition, some of these changes 
could have a more significant impact on us as compared to other REITs due to the nature of our business and our substantial use 
of TRSs, particularly non-United States TRSs, or how we have structured our operations outside the United States to comply with 
REIT qualification requirements. We cannot predict with certainty whether, when, in what forms, or with what effective dates, the tax 
laws, regulations, administrative interpretations or local laws applicable to us may be changed or if such laws would impact our 
ability to remain qualified for taxation as a REIT or the costs of doing so. 

GENERAL RISK FACTORS

Our cash distributions are not guaranteed and may fluctuate.

As a REIT, we are generally required to distribute at least 90% of our REIT taxable income to our stockholders. Furthermore, we 
are committed to growing our dividends, and have stated this publicly.

Our board of directors, in its sole discretion, will determine, on a quarterly basis, the amount of cash to be distributed to our 
stockholders based on a number of factors including, but not limited to, our results of operations, cash flow and capital 
requirements, economic conditions, tax considerations, borrowing capacity and other factors, including debt covenant restrictions 
that may impose limitations on cash payments, future acquisitions and divestitures, any stock repurchase program and general 
market demand for our space and related services. Consequently, our distribution levels may fluctuate and we may not be able to 
meet our public commitments with respect to dividend growth.

Our business could be adversely impacted if there are deficiencies in our disclosure controls and procedures or internal control 
over financial reporting.

The design and effectiveness of our disclosure controls and procedures and internal control over financial reporting may not 
prevent all errors, misstatements or misrepresentations. While management will continue to review the effectiveness of our 
disclosure controls and procedures and internal control over financial reporting, there can be no guarantee that our internal control 
over financial reporting will be effective in accomplishing all control objectives all of the time. Furthermore, our disclosure controls 
and procedures and internal control over financial reporting with respect to entities that we do not control or manage may be 
substantially more limited than those we maintain with respect to the subsidiaries that we have controlled or managed over the 
course of time. Deficiencies, including any material weakness, in our internal control over financial reporting which may occur in the 
future could result in misstatements of our results of operations, restatements of our financial statements, a decline in our stock 
price, or otherwise materially adversely affect our business, reputation, results of operations, financial condition or liquidity.

We face competition for customers.

We compete with multiple businesses in all geographic areas where we operate; our current or potential customers may choose to 
use those competitors instead of us. In addition, if we are successful in winning customers from competitors, the process of moving 
their stored records into our facilities is often costly and time consuming. We also compete, in some of our business lines, with our 
current and potential customers’ internal storage and information management services capabilities and their cloud-based 
alternatives. These organizations may not begin or continue to use us for their future storage and information management service 
needs.

The performance of our businesses relies on our ability to attract, develop, and retain talented personnel, while controlling our labor 
costs.

We are highly dependent on skilled and qualified personnel to operate our businesses. The failure to attract and retain qualified 
employees or to effectively control our labor costs could negatively affect our competitive position and operating results. Our ability 
to control labor costs and attract qualified personnel is subject to numerous external factors, including prevailing wages, labor 
shortages, the impact of legislation or regulations governing wages and hours, labor relations, immigration, healthcare and other 
benefits, other employment-related costs and the hiring practices of our competitors.

The leased facilities typically have initial lease terms of five to 10 years with one or more renewal options. In addition, some of the 
leases contain either a purchase option or a right of first refusal upon the sale of the property. We believe that the space available 
in our facilities is adequate to meet our current needs, although future growth may require that we lease or purchase additional real 
property.

OVERVIEW

COVID-19

In March 2020, the World Health Organization declared a novel strain of coronavirus (“COVID-19”) a pandemic. While we have 
broad geographic and customer diversification with operations in 63 countries and no single customer accounting for more than 
approximately 1% of revenue during the year ended December 31, 2021, COVID-19 is a global pandemic impacting numerous 
industries and geographies. While our service operations have increased from the reductions we experienced during the first and 
second quarter of 2020, future service revenues remain uncertain and will be dependent on the severity of the COVID-19 
pandemic, including new variants of COVID-19 that may emerge. 

PROJECT SUMMIT

In October 2019, we announced Project Summit, our global program designed to better position us for future growth and 
achievement of our strategic objectives. As of December 31, 2021, we have completed Project Summit. As a result of the program 
we have simplified our global structure, rebalanced resources to focus on higher growth areas, realigned our management 
structure to create a more dynamic, agile organization, made investments to enhance the customer experience and leveraged new 
technology solutions that enabled us to modernize our service delivery model and more efficiently utilize our fleet, labor and real 
estate. Project Summit has improved annual Adjusted EBITDA (as defined below) by approximately $375.0 million exiting 2021, of 
which approximately $160.0 million and $165.0 million were realized in 2021 and 2020, respectively, with the remainder to come in 
2022. 

2021

Exiting 2021

$160 million

$375 million

The implementation of Project Summit resulted in total operating expenditures ("Restructuring Charges") of approximately $450.0 
million that primarily consisted of: (1) employee severance costs; (2) internal costs associated with the development and 
implementation of Project Summit initiatives; (3) professional fees, primarily related to third party consultants who assisted with the 
design and execution of various initiatives as well as project management activities and (4) system implementation and data 
conversion costs. The following table presents (in millions) total Restructuring Charges related to Project Summit from the inception 
of Project Summit through December 31, 2021 and for the years ended December 31, 2021, 2020 and 2019:

DIVESTMENTS

Part II

INTELLECTUAL PROPERTY MANAGEMENT BUSINESS  
On June 7, 2021, we sold our Intellectual Property Management ("IPM") business, also known as our technology escrow services 
business, which we predominantly operated in the United States, for total gross consideration of approximately $215.4 million (the 
“IPM Divestment”). As a result of the IPM Divestment, we recorded a gain on sale of approximately $179.0 million to Other 
(income) expense, net, during the year ended December 31, 2021, the substantial majority of which was recorded during the 
second quarter of 2021, representing the excess of the fair value of the consideration received over the sum of the carrying value 
of the IPM business. Our IPM business represented approximately $14.2 million, $32.8 million and $33.2 million of total revenues 
for the years ended December 31, 2021, 2020 and 2019, respectively, and approximately $6.8 million, $16.0 million and $17.2 
million of total net income for the years ended December 31, 2021, 2020 and 2019, respectively.

IRON MOUNTAIN CONSUMER STORAGE 
In March 2019, we contributed our customer contracts and certain intellectual property and other assets used by us to operate our 
consumer storage business in the United States and Canada (the “IM Consumer Storage Assets”) and approximately $20.0 million 
in cash (gross of certain transaction expenses) (the “Cash Contribution”) to a strategic partnership (the “MakeSpace JV”) 
established by us and MakeSpace Labs, Inc. (“MakeSpace”) pursuant to a transaction which closed on March 19, 2019 (the 
"Consumer Storage Transaction"). Upon the closing of the Consumer Storage Transaction, the MakeSpace JV owned (i) the IM 
Consumer Storage Assets, (ii) the Cash Contribution and (iii) the customer contracts, intellectual property and certain other assets 
used by MakeSpace to operate its consumer storage business in the United States. As part of the Consumer Storage Transaction, 
we received an initial equity interest of approximately 34% in the MakeSpace JV (the “MakeSpace Investment”). In the second 
quarter of 2020, we committed to participate in a round of equity funding for the MakeSpace JV whereby we contributed $36.0 
million of the $45.0 million being raised in installments between May 2020 through October 2021. At December 31, 2021, we 
owned 49.99% of the outstanding equity in the MakeSpace JV. 

In connection with the Consumer Storage Transaction and the MakeSpace Investment, we also entered into a storage and service 
agreement with the MakeSpace JV to provide certain storage and related services to the MakeSpace JV (the “MakeSpace 
Agreement”). Revenues and expenses associated with the MakeSpace Agreement are presented as a component of our Global 
RIM Business segment. During the years ended December 31, 2021, 2020 and 2019, we recognized revenue of approximately 
$34.7 million, $33.6 million and $22.5 million, respectively, associated with the MakeSpace Agreement.

As a result of the Consumer Storage Transaction, we recorded a gain on sale of approximately $4.2 million to Other (income) 
expense, net, during the first quarter of 2019, representing the excess of the fair value of the consideration received over the sum 
of the carrying value of our consumer storage operations and (ii) the Cash Contribution.

________________________________________________________

As described in Note 4 to Notes to Consolidated Financial Statements included in this Annual Report, we have concluded that the 
divestments of IPM and the IM Consumer Storage Assets in the Consumer Storage Transaction do not meet the criteria to be 
reported as discontinued operations in our consolidated financial statements. 

GENERAL

RESULTS OF OPERATIONS - KEY TRENDS 

•

In spite of the COVID-19 pandemic, we have experienced relatively steady volume in our Global RIM Business segment, with 
organic storage rental revenue growth driven primarily by revenue management. We expect organic storage rental revenue 
growth to benefit from revenue management and volume to be relatively stable in the near term.

• Our organic service revenue growth is primarily due to increases in our service activity, particularly in regions where 

governments have lifted or eased COVID-19-related restrictions on our customers’ non-essential business operations. We 
expect organic service revenue growth in 2022 to benefit from our new and existing digital offerings.

• We expect revenue and Adjusted EBITDA growth to accelerate in 2022 with continued focus on new product and service 

offerings, innovation, customer solutions and market expansion.  

IRON MOUNTAIN 2021 FORM 10-K

Table of Contents

Part II

Our revenues consist of storage rental revenues as well as service revenues and are reflected net of sales and value-added taxes. 
Storage rental revenues, which are considered a key driver of financial performance for the storage and information management 
services industry, consist primarily of recurring periodic rental charges related to the storage of materials or data (generally on a per 
unit basis) that are typically retained by customers for many years and revenues associated with our data center operations. 
Service revenues include charges for related service activities, the most significant of which include: (1) the handling of records, 
including the addition of new records, temporary removal of records from storage, refiling of removed records, customer termination 
and permanent withdrawal fees, project revenues, and courier operations, consisting primarily of the pickup and delivery of records 
upon customer request; (2) destruction services, consisting primarily of secure shredding of sensitive documents and the 
subsequent sale of shredded paper for recycling, the price of which can fluctuate from period to period; (3) digital solutions, 
including the scanning, imaging and document conversion services of active and inactive records, and consulting services; and (4) 
data center services, including set up, monitoring and support of our customers' assets which are protected in our data center 
facilities, and special project services, including data center fitout. Our service revenue growth has been negatively impacted by 
declining activity rates as stored records are becoming less active. While customers continue to store their records and tapes with 
us, they are less likely than they have been in the past to retrieve records for research and other purposes, thereby reducing 
service activity levels.

BREAKDOWN OF REVENUES 

Cost of sales (excluding depreciation and amortization) consists primarily of labor, including wages and benefits for field personnel, 
facility occupancy costs (including rent and utilities), transportation expenses (including vehicle leases and fuel), other product cost 
of sales and other equipment costs and supplies. Of these, labor and facility occupancy costs are the most significant. Selling, 
general and administrative expenses consist primarily of wages and benefits for management, administrative, IT, sales, account 
management and marketing personnel, as well as expenses related to communications and data processing, travel, professional 
fees, bad debts, training, office equipment and supplies. 

Cost of sales (excluding depreciation and amortization) and Selling, general and administrative expenses for the year ended 
December 31, 2021 consists of the following: 

COST OF SALES

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES

30

IRON MOUNTAIN 2021 FORM 10-K

Table of Contents

Part II

Trends in facility occupancy costs are impacted by:

•
•

•

•

the total number of facilities we occupy;
the mix of properties we own versus properties we lease;
fluctuations in per square foot occupancy costs; and
the levels of utilization of these properties.

Trends in total wages and benefits in dollars and as a percentage of total consolidated revenue are influenced by:

• changes in headcount and compensation levels;
• achievement of incentive compensation targets;
• workforce productivity; and
• variability in costs associated with medical insurance and workers’ compensation.

The expansion of our international businesses has impacted the major cost of sales components and selling, general and 
administrative expenses.

• Our international operations are more labor intensive relative to revenue than our operations in North America and, 

therefore, labor costs are a higher percentage of international operational revenue.

• The overhead structure of our expanding international operations has generally not achieved the same level of overhead 

leverage as our North American operations, which may result in an increase in selling, general and administrative expenses 
as a percentage of consolidated revenue as our international operations become a larger percentage of our consolidated 
results.

Our depreciation and amortization charges result primarily from depreciation related to storage systems, which include racking 
structures, buildings, building and leasehold improvements and computer systems hardware and software. Amortization relates 
primarily to customer relationship intangible assets, contract fulfillment costs and data center lease-based intangible assets. Both 
depreciation and amortization are impacted by the timing of acquisitions. 

Our consolidated revenues and expenses are subject to the net effect of foreign currency translation related to our operations 
outside the United States. It is difficult to predict the future fluctuations of foreign currency exchange rates and how those 
fluctuations will impact our Consolidated Statements of Operations. As a result of the relative size of our international operations, 
these fluctuations may be material on individual balances. Our revenues and expenses from our international operations are 
generally denominated in the local currency of the country in which they are derived or incurred. Therefore, the impact of currency 
fluctuations on our operating income and operating margin is partially mitigated. In order to provide a framework for assessing how 
our underlying businesses performed excluding the effect of foreign currency fluctuations, we compare the percentage change in 
the results from one period to another period in this report using constant currency presentation. The constant currency growth 
rates are calculated by translating the 2020 results at the 2021 average exchange rates and the 2019 results at the 2020 average 
exchange rates. Constant currency growth rates are a non-GAAP measure.

NON-GAAP MEASURES

ADJUSTED EBITDA

Adjusted EBITDA is defined as income (loss) from continuing operations before interest expense, net, provision (benefit) for income 
taxes, depreciation and amortization (inclusive of our share of Adjusted EBITDA from our unconsolidated joint ventures), and 
excluding certain items we do not believe to be indicative of our core operating results, specifically:

EXCLUDED

• Acquisition and Integration Costs

• Other (income) expense, net

• Restructuring Charges

•

•

Intangible impairments

(Gain) loss on disposal/write-down of property, plant and 
equipment, net (including real estate)

• Stock-based compensation expense

• COVID-19 Costs (as defined below)

Adjusted EBITDA Margin is calculated by dividing Adjusted EBITDA by total revenues. We also show Adjusted EBITDA and 
Adjusted EBITDA Margin for each of our reportable operating segments under “Results of Operations – Segment Analysis” below.

IRON MOUNTAIN 2021 FORM 10-K

 
 
 
 
Table of Contents

Part II

Adjusted EBITDA excludes both interest expense, net and the provision (benefit) for income taxes. These expenses are associated 
with our capitalization and tax structures, which we do not consider when evaluating the operating profitability of our core 
operations. Adjusted EBITDA also does not include depreciation and amortization expenses, in order to eliminate the impact of 
capital investments, which we evaluate by comparing capital expenditures to incremental revenue generated and as a percentage 
of total revenues. Adjusted EBITDA and Adjusted EBITDA Margin should be considered in addition to, but not as a substitute for, 
other measures of financial performance reported in accordance with accounting principles generally accepted in the United States 
of America (“GAAP”), such as operating income, income (loss) from continuing operations, net income (loss) or cash flows from 
operating activities from continuing operations (as determined in accordance with GAAP).

ADJUSTED EPS

Adjusted EPS is defined as reported earnings per share fully diluted from continuing operations (inclusive of our share of adjusted 
losses (gains) from our unconsolidated joint ventures) and excluding certain items, specifically:

EXCLUDED

• Acquisition and Integration Costs

• Other (income) expense, net 

• Restructuring Charges

• COVID-19 Costs

(Gain) loss on disposal/write-down of property, plant and 
equipment, net (including real estate)

• Tax impact of reconciling items and discrete tax items 

We do not believe these excluded items to be indicative of our ongoing operating results, and they are not considered when we are 
forecasting our future results. We believe Adjusted EPS is of value to our current and potential investors when comparing our 
results from past, present and future periods.

have an insignificant impact on our reported provision (benefit) for income taxes and (ii) other discrete tax items. Our structural tax rate for purposes of the calculation 
of Adjusted EPS for the years ended December 31, 2021, 2020 and 2019 was 17.7%, 15.1%, and 17.6%, respectively.

FFO (NAREIT) AND FFO (NORMALIZED)

Funds from operations ("FFO") is defined by the National Association of Real Estate Investment Trusts (“Nareit”) as net income 
(loss) excluding depreciation on real estate assets, gains on sale of real estate, net of tax, and amortization of data center leased-
based intangibles. FFO (Nareit) does not give effect to real estate depreciation because these amounts are computed, under 
GAAP, to allocate the cost of a property over its useful life. Because values for well-maintained real estate assets have historically 
increased or decreased based upon prevailing market conditions, we believe that FFO (Nareit) provides investors with a clearer 
view of our operating performance. Our most directly comparable GAAP measure to FFO (Nareit) is net income (loss).

Although Nareit has published a definition of FFO, we modify FFO (Nareit), as is common among REITs seeking to provide 
financial measures that most meaningfully reflect their particular business ("FFO (Normalized)"). Our definition of FFO (Normalized) 
excludes certain items included in FFO (Nareit) that we believe are not indicative of our core operating results, specifically:

EXCLUDED
• Acquisition and Integration Costs

• Restructuring Charges

• Stock-based compensation expense

• COVID-19 Costs

•

•

Intangible impairments

• Real estate financing lease depreciation

(Gain) loss on disposal/write-down of property, plant and 
equipment, net (excluding real estate)

• Tax impact of reconciling items and discrete tax items

•

(Income) loss from discontinued operations, net of tax

• Other (income) expense, net

CRITICAL ACCOUNTING ESTIMATES

Our discussion and analysis of our financial condition and results of operations are based upon our Consolidated Financial 
Statements, which have been prepared in accordance with GAAP. The preparation of these financial statements requires us to 
make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and 
related disclosure of contingent assets and liabilities at the date of the financial statements and for the period then ended. On an 
ongoing basis, we evaluate the estimates used. We base our estimates on historical experience, actuarial estimates, current 
conditions and various other assumptions that we believe to be reasonable under the circumstances. These estimates form the 
basis for making judgments about the carrying values of assets and liabilities and are not readily apparent from other sources. 
Actual results may differ from these estimates. The following should be read in conjunction with Note 2 to Notes to Consolidated 
Financial Statements included in this Annual Report, which provides a summary of our significant accounting policies. Our critical 
accounting estimates include the following, which are listed in no particular order:

Part II

REVENUE RECOGNITION 

Revenue is recognized when or as control of promised goods or services is transferred to the customer, in an amount that reflects 
the consideration we expect to be entitled to in exchange for those goods or services. See Note 2.r. to Notes to Consolidated 
Financial Statements included in this Annual Report for additional details on our revenue recognition policies. Revenue for all our 
lines of business, with the exception of storage revenues in our Global Data Center Business (which is subject to leasing 
guidance), is recognized in accordance with Accounting Standards Codification ("ASC") 606, Revenue from Contracts with 
Customers (“ASC 606”), the application of which requires that we make estimates and judgements that may affect the amount and 
timing of revenue we recognize. 

We have determined that the majority of our contracts contain series performance obligations which qualify to be recognized under 
a practical expedient available in ASC 606 known as the “right to invoice.” This determination allows variable consideration in such 
contracts to be allocated to and recognized in the period to which the consideration relates, which is typically the period in which it 
is billed, rather than requiring estimation of variable consideration at the inception of the contract.  

From time to time, we make payments to entities that are also customers under a revenue contract. These payments are 
comprised of Customer Inducements (as defined in Note 2.l. to Notes to Consolidated Financial Statements included in this Annual 
Report). Consideration payable to a customer is treated as a reduction of the transaction price over periods ranging from one to 10 
years. If the payment to the customer does not represent payment for a distinct service, revenue is recognized only up to the 
amount of consideration remaining after customer payment obligations are considered.   

Contract Fulfillment Costs are amortized over a three year term, which we have determined is consistent with the transfer of the 
underlying performance obligations to which the assets relate. Different determinations on term length would result in differences in 
the amount and timing of amortization expense recognized.

ACCOUNTING FOR ACQUISITIONS

Part of our growth strategy has been to acquire businesses. The purchase price of each acquisition has been determined after due 
diligence of the target business, market research, strategic planning and the forecasting of expected future results and synergies. 
Estimated future results and expected synergies are subject to revisions as we integrate each acquisition and attempt to leverage 
resources. 

Accounting for acquisitions of a business has resulted in the capitalization of the cost in excess of the estimated fair value of the 
net assets acquired in each of these acquisitions as goodwill. We estimate the fair values of the assets acquired in each acquisition 
as of the date of acquisition and these estimates are subject to adjustment based on the final assessments of the fair value of 
intangible assets (primarily customer relationship and data center lease-based intangible assets), property, plant and equipment 
(primarily building, building improvements, leasehold improvements, data center infrastructure and racking structures), operating 
leases, contingencies and income taxes (primarily deferred income taxes). See Note 3 to Notes to Consolidated Financial 
Statements included in this Annual Report for a description of recent acquisitions. 

Determining the fair values of the net assets acquired requires management’s judgment and often involves the use of assumptions 
with respect to future cash inflows and outflows, discount rates and market data, among other items. As it relates to our data center 
acquisitions, the fair values of the net assets acquired requires management’s judgment and often involves the use of assumptions 
with respect to (i) certain economic costs (as described more fully in Note 2.l. to Notes to Consolidated Financial Statements 
included in this Annual Report) avoided by acquiring a data center operation with active tenants that would have otherwise been 
incurred if the data center operation was purchased vacant, (ii) market rental rates and (iii) expectations of lease renewals and 
extensions. Due to the inherent uncertainty of future events, actual values of net assets acquired could be different from our 
estimated fair values and could have a material impact on our financial statements.

Of the net assets acquired in our acquisitions, the fair value of owned buildings, including building improvements, customer 
relationship and data center lease-based intangible assets, racking structures and operating leases are generally the most 
common and most significant. For significant acquisitions or acquisitions involving new markets or new products, we generally use 
third parties to assist us in estimating the fair value of owned buildings, including building improvements, customer relationship and 
lease-based intangible assets and market rental rates for acquired operating leases. For acquisitions that are not significant or do 
not involve new markets or new products, we generally use third parties to assist us in estimating the fair value of acquired owned 
buildings, including building improvements, and market rental rates for acquired operating leases. When not using third party 
appraisals of the fair value of acquired net assets, the fair value of acquired customer relationship intangible assets, above and 
below market in-place operating leases, and racking structures is determined internally. The fair value of acquired racking 
structures is determined internally by taking current estimated replacement cost at the date of acquisition for the quantity of racking 
structures acquired, discounted to take into account the quality (e.g. age, material and type) of the racking structures. We use 
discounted cash flow models to determine the fair value of customer relationship assets, which requires a significant amount of 
judgment by management, including estimating expected lives of the relationships, expected future cash flows and discount rates. 
We determine the fair value of tangible data center assets using an estimated replacement cost at the date of acquisition, then 
discounting for age, economic and functional obsolescence.

IRON MOUNTAIN 2021 FORM 10-K

Part II

Our estimates of fair value are based upon assumptions believed to be reasonable at that time but which are inherently uncertain 
and unpredictable. Assumptions may be incomplete or inaccurate, and unanticipated events and circumstances may occur, which 
may affect the accuracy of such assumptions. Total property, plant and equipment and intangible assets acquired in our 2021 
acquisitions were approximately $150.1 million and $44.9 million, respectively.

IMPAIRMENT OF TANGIBLE AND INTANGIBLE ASSETS 

ASSETS SUBJECT TO DEPRECIATION OR AMORTIZATION 

We review long-lived assets and all finite-lived intangible assets for impairment whenever events or changes in circumstances 
indicate the carrying amount of such assets may not be recoverable. Examples of events or circumstances that may be indicative 
of impairment include, but are not limited to:

• A significant decrease in the market price of an asset;

• A significant change in the extent or manner in which a long-lived asset is being used or in its physical condition;

• A significant adverse change in legal factors or in the business climate that could affect the value of the asset;

• An accumulation of costs significantly greater than the amount originally expected for the acquisition or construction of an asset;

• A current-period operating or cash flow loss combined with a history of operating or cash flow losses or a projection or forecast 

that demonstrates continuing losses associated with the use of a long-lived asset; and

• A current expectation that, more likely than not, an asset will be sold or otherwise disposed of significantly before the end of its 

previously estimated useful life.

If events indicate the carrying value of such assets may not be recoverable, recoverability of these assets is determined by 
comparing the sum of the forecasted undiscounted net cash flows of the operation to which the assets relate to their carrying 
amount. The operations are generally distinguished by the business segment and geographic region in which they operate. If it is 
determined that we are unable to recover the carrying amount of the assets, the long-lived assets are written down, on a pro rata 
basis, to fair value. Fair value is determined based on discounted cash flows or appraised values, depending upon the nature of the 
assets.

We did not record impairment charges for any of our long-lived asset and finite-lived intangibles during the years ended December 
31, 2021 and 2020. During 2019, we recorded an impairment charge of approximately $24.0 million on the assets associated with 
the select offerings within our Iron Mountain Iron Cloud portfolio as we explored strategic options regarding how to maintain and 
support the infrastructure of select offerings within this portfolio.  

GOODWILL AND OTHER INDEFINITE-LIVED INTANGIBLE ASSETS NOT SUBJECT TO 
AMORTIZATION

Goodwill and intangible assets with indefinite lives are not amortized but are reviewed annually for impairment, or more frequently if 
impairment indicators arise. Other than goodwill, we currently have no intangible assets that have indefinite lives and which are not 
amortized. See Note 2.k. to Notes to Consolidated Financial Statements included in this Annual Report for additional details on our 
goodwill and other indefinite-lived intangible assets policies.  

We have selected October 1 as our annual goodwill impairment review date. We have performed our annual goodwill impairment 
review as of October 1, 2021, 2020 and 2019. We concluded that as of October 1, 2021, 2020 and 2019, goodwill was not 
impaired. 

Our reporting units at which level we performed our goodwill impairment analysis as of October 1, 2021 were as follows:

• North American Records and Information Management reporting 

• Asia Records and Information Management reporting unit ("Asia 

unit ("North America RIM")

RIM")

• Europe Records and Information Management reporting unit 

• Global Data Center

("Europe RIM")

• Latin America Records and Information Management reporting 

unit ("Latin America RIM")

• Australia and New Zealand Records and Information Management 

reporting unit ("ANZ RIM")

• Fine Arts

• Entertainment Services

Based on our goodwill impairment analysis as of October 1, 2021, all of our reporting units had estimated fair values exceeding 
their carrying values by greater than 20%. Our Global Data Center reporting unit had an estimated fair value that exceeded its 
carrying value by approximately 23%. The reporting unit represented approximately $426.1 million, or 9.5%, of our consolidated 
goodwill balance at December 31, 2021. The following is a summary of the Global Data Center reporting unit including the goodwill 
balance (in thousands), percentage by which the fair value of the reporting unit exceeded its carrying value, and certain key 
assumptions used by us in determining the fair value of the reporting unit as of October 1, 2021:

For purposes of our goodwill impairment analysis, the term “capital expenditures” includes both growth investment and recurring capital expenditures. The capital 
expenditure assumptions in our goodwill impairment analysis include significant growth investment in the next three years.    

Terminal growth rates are applied in year 10 of our discounted cash flow analysis.

Reporting unit valuations have generally been determined using a combined approach based on the present value of future cash 
flows (the “Discounted Cash Flow Model”) and market multiples (the “Market Approach"). There are inherent uncertainties and 
judgments involved when determining the fair value of the reporting units for purposes of our annual goodwill impairment testing. 
The following includes supplemental information to the table above for the Data Center reporting unit where the estimated fair value 
exceeded its carrying value by approximately 23% as of October 1, 2021. The success of this business and the achievement of 
certain key assumptions developed by management and used in the Discounted Cash Flow Model are contingent upon various 
factors including, but not limited to, (i) achieving growth from existing customers, (ii) sales to new customers, (iii) increased market 
penetration and (iv) accurately timing the capital investments related to expansions.

Our Global Data Center Business footprint spans nine markets in the United States: Denver, Colorado; Kansas City, Missouri; 
Boston, Massachusetts; Boyers, Pennsylvania; Manassas, Virginia; Edison, New Jersey; Columbus, Ohio; and Phoenix and 
Scottsdale, Arizona and seven international markets: Amsterdam, London, Singapore, Frankfurt (directly and through an 
unconsolidated joint venture) and through unconsolidated joint ventures in Mumbai, Pune and Noida. We provide enterprise-class 
data center facilities and hyperscale-ready capacity to protect mission-critical assets and ensure the continued operation of our 
customers’ IT infrastructure with secure, reliable and flexible data center options. Data centers are highly specialized and secure 
assets that serve as centralized repositories of server, storage and network equipment. They are capital intensive and designed to 
provide the space, power, cooling and network connectivity necessary to efficiently operate mission-critical IT equipment. The 
demand for data center infrastructure is being driven by many factors, but most importantly by significant growth in data as well as 
an increased demand for outsourcing. In order to attract and retain customers, as well as sustain growth in our existing and new 
markets, we must have the capability to tailor our facilities and invest capital to meet our customers’ needs. Our estimate of fair 
value reflects the expected growth in each of our data center markets along with the corresponding capital investments required to 
meet demand. The business is primarily comprised of acquisitions completed in 2018 and late 2017; therefore, we would expect 
that the fair value of this reporting unit would closely approximate its carrying value.

Key factors that could reasonably be expected to have a negative impact on the estimated fair value of these reporting units and 
potentially result in impairment charges include, but are not limited to: (i) a deterioration in general economic conditions, (ii) 
significant adverse changes in regulatory factors or in the business climate, and (iii) adverse actions or assessment by regulators, 
all of which could result in adverse changes to the key assumptions used in valuing the reporting units. The inability to meet the 
assumptions used in the Discounted Cash Flow Model and Market Approach for each of the reporting units, or future adverse 
market conditions not currently known, could lead to a fair value that is less than the carrying value in any one of our reporting 
units. 

Reporting unit valuations have generally been determined using a combined approach based on the Discounted Cash Flow Model 
and Market Approach. The Discounted Cash Flow Model incorporates significant assumptions including future revenue growth 
rates, operating margins, discount rates and capital expenditures. The Market Approach requires us to make assumptions related 
to Adjusted EBITDA multiples. Changes in economic and operating conditions impacting these assumptions or changes in multiples 
could result in goodwill impairments in future periods. In conjunction with our annual goodwill impairment reviews, we reconcile the 
sum of the valuations of all of our reporting units to our market capitalization as of such dates.

IRON MOUNTAIN 2021 FORM 10-K

Part II

Although we believe we have sufficient historical and projected information available to us to test for goodwill impairment, it is 
possible that actual results could differ from the estimates used in our impairment tests. Of the key assumptions that impact the 
goodwill impairment test, the expected future cash flows and discount rate are among the most sensitive and are considered to be 
critical assumptions, as changes to these estimates could have an effect on the estimated fair value of each of our reporting units. 
We have assessed the sensitivity of these assumptions on each of our reporting units as of October 1, 2021. 

North America RIM, Europe
RIM, Latin America RIM, ANZ
RIM, Asia RIM, Fine Arts and 
Entertainment Services

We noted that, based on the estimated fair value of these reporting units determined as of 
October 1, 2021:

• a hypothetical decrease of 10% in the expected annual future cash flows of these reporting 
units, with all other assumptions unchanged, would have decreased the estimated fair value 
of these reporting units as of October 1, 2021 by a range of approximately 9.7% to 10.6% 
but would not, however, have resulted in the carrying value of any of these reporting units 
with goodwill exceeding their estimated fair value;

• a hypothetical increase of 100 basis points in the discount rate, with all other assumptions 
unchanged, would have decreased the estimated fair value of these reporting units as of 
October 1, 2021 by a range of approximately 4.2% to 9.9% but would not, however, have 
resulted in the carrying value of any of these reporting units with goodwill exceeding their 
estimated fair value.

Global Data Center

We noted that, as of October 1, 2021, the estimated fair value of the reporting unit:

• exceeds its carrying value by approximately 23%.

Accordingly, any significant negative change in either the expected annual future cash flows of 
the reporting unit or the discount rate may result in the carrying value of the reporting unit 
exceeding its estimated fair value.

At December 31, 2021, no factors were identified that would alter the conclusions of our October 1, 2021 goodwill impairment 
analysis. In making this assessment, we considered a number of factors including operating results, business plans, anticipated 
future cash flows, transactions and marketplace data. There are inherent uncertainties related to these factors and our judgment in 
applying them to the analysis of goodwill impairment.

INCOME TAXES

As a REIT, we are generally permitted to deduct from our federal taxable income the dividends we pay to our stockholders. The 
income represented by such dividends is not subject to federal taxation at the entity level but is taxed, if at all, at the stockholder 
level. The income of our domestic TRSs, which hold our domestic operations that may not be REIT-compliant as currently operated 
and structured, is subject, as applicable, to federal and state corporate income tax. In addition, we and our subsidiaries continue to 
be subject to foreign income taxes in other jurisdictions in which we have business operations or a taxable presence, regardless of 
whether assets are held or operations are conducted through subsidiaries disregarded for federal income tax purposes or TRSs. 
We will also be subject to a separate corporate income tax on any gains recognized on the sale or disposition of any asset 
previously owned by a C corporation during a five-year period after the date we first owned the asset as a REIT asset that are 
attributable to "built-in gains" with respect to that asset on that date. We will also be subject to a built-in gains tax on our 
depreciation recapture recognized into income as a result of accounting method changes in connection with our acquisition 
activities. If we fail to remain qualified for taxation as a REIT, we will be subject to federal income tax at regular corporate income 
tax rates. Even if we remain qualified for taxation as a REIT, we may be subject to some federal, state, local and foreign taxes on 
our income and property in addition to taxes owed with respect to our TRS operations. In particular, while state income tax regimes 
often parallel the federal income tax regime for REITs, many states do not completely follow federal rules and some do not follow 
them at all. See Note 10 to Notes to Consolidated Financial Statements included in this Annual Report for additional details on our 
tax policies.

Accounting for income taxes requires the recognition of deferred tax assets and liabilities for the expected future tax consequences 
of temporary differences between the tax and financial reporting bases of assets and liabilities and for loss and credit 
carryforwards. We measure deferred tax assets and liabilities using enacted tax rates expected to be applied to taxable income in 
the years in which those temporary differences and carryforwards are expected to be recovered or settled. The effect on deferred 
tax assets and liabilities as a result of a change in tax rates is recognized in income in the period that the change is enacted. 
Valuation allowances are provided when recovery of deferred tax assets does not meet the more likely than not standard as 
defined in GAAP. Valuation allowances would be reversed as a reduction to the provision for income taxes if related deferred tax 
assets are deemed realizable based on changes in facts and circumstances relevant to the recoverability of the asset.

IRON MOUNTAIN 2021 FORM 10-K

39

Table of Contents

Part II

At December 31, 2021, we have federal and state net operating loss carryforwards of which we are expecting an insignificant tax 
benefit to be realized. We have assets for foreign net operating losses of $85.5 million, with various expiration dates (and in some 
cases no expiration date), subject to a valuation allowance of approximately 47%. If actual results differ unfavorably from certain of 
our estimates used, we may not be able to realize all or part of our net deferred income tax assets and additional valuation 
allowances may be required. Although we believe our estimates are reasonable, no assurance can be given that our estimates 
reflected in the tax provisions and accruals will equal our actual results. These differences could have a material impact on our 
income tax provision and operating results in the period in which such determination is made.

The evaluation of an uncertain tax position is a two-step process. The first step is a recognition process whereby we determine 
whether it is more likely than not that a tax position will be sustained upon examination, including resolution of any related appeals 
or litigation processes, based on the technical merits of the position. The second step is a measurement process whereby a tax 
position that meets the more likely than not recognition threshold is calculated to determine the amount of benefit to recognize in 
the financial statements. The tax position is measured as the largest amount of benefit that is greater than 50% likely of being 
realized upon ultimate settlement.

We are subject to income taxes in the United States and numerous foreign jurisdictions. We are subject to examination by various 
tax authorities in jurisdictions in which we have business operations or a taxable presence. We regularly assess the likelihood of 
additional assessments by tax authorities and provide for these matters as appropriate. As of December 31, 2021 and 2020, we 
had approximately $27.8 million and $26.0 million, respectively, of reserves related to uncertain tax positions. The reversal of these 
reserves will be recorded as a reduction of our income tax provision if sustained. Although we believe our tax estimates are 
appropriate, the final determination of tax audits and any related litigation could result in changes in our estimates.

Following our conversion to a REIT in 2014, we concluded that it was not our intent to reinvest our current and future undistributed 
earnings of our foreign subsidiaries indefinitely outside the United States. As of December 31, 2016, we concluded that it is our 
intent to indefinitely reinvest our current and future undistributed earnings of certain of our unconverted foreign TRSs outside the 
United States. During 2021, as a result of the enactment of a tax law and the closing of various acquisitions, we reassessed this 
intention and concluded that it is no longer our intention to reinvest our undistributed earnings of our foreign TRSs indefinitely 
outside the United States. As a REIT, future repatriation of incremental undistributed earnings of our foreign subsidiaries will not be 
subject to federal or state income tax, with the exception of foreign withholding taxes. However, such future repatriations may 
require distributions to our stockholders in accordance with REIT distribution rules, and any such distribution may then be taxable, 
as appropriate, at the stockholder level. We expect to provide for foreign withholding taxes on the current and future earnings of all 
of our foreign subsidiaries as the result of such reassessment.

(1) Constant currency growth rates are calculated by translating the 2020 results at the 2021 average exchange rates and the 2019 results at the 2020 average 

exchange rates.

(2) Our organic revenue growth rate, which is a non-GAAP measure, represents the year-over-year growth rate of our revenues excluding the impact of business 

acquisitions, divestitures and foreign currency exchange rate fluctuations, but including the impact of acquisitions of customer relationships.

TOTAL REVENUES

For the year ended December 31, 2021, the increase in reported consolidated revenue was driven by reported storage rental 
revenue growth and reported service revenue growth. Foreign currency exchange rate fluctuations increased our reported 
consolidated revenues by 1.5% in the year ended December 31, 2021 compared to the prior year period.

STORAGE RENTAL REVENUES AND SERVICE REVENUES

Primary factors influencing the change in reported storage rental revenue and reported service revenue for the year ended 
December 31, 2021 compared to the year ended December 31, 2020 include the following: 

STORAGE RENTAL REVENUES • organic storage rental revenue growth driven by increased volume in faster growing 
markets and our Global Data Center Business segment and revenue management;
• a 2.4% increase in total global volume (excluding acquisitions, total global volume 

increased 0.2%); and

• an increase of $37.7 million due to foreign currency exchange rate fluctuations.

SERVICE REVENUES

• an increase in service activity levels, particularly in regions where governments have lifted 

or eased COVID-19 related restrictions on our customers' non-essential business 
operations;

• organic service revenue growth reflecting increased service activity levels; and

• an increase of $20.8 million due to foreign currency exchange rate fluctuations.

Primary factors influencing the change in reported consolidated Cost of sales for the year ended December 31, 2021 compared to

• an increase in labor costs driven by an increase in service activity, particularly in regions where governments have lifted or 
eased COVID-19 related restrictions on our customers' non-essential business operations, partially offset by benefits from 
Project Summit;

• an increase in facilities expenses driven by increases in rent expense, reflecting the impact from our sale-leaseback activity 
during the years ended December 31, 2020 and 2021 (which we expect to continue in 2022 as we continue to look for future 
opportunities to monetize a small portion of our owned industrial real estate assets as part of our ongoing capital recycling 
program), as well as increases in utilities and property taxes; 

• an increase in product cost of sales and other driven by an increase in project activity; and

• an increase of $25.8 million due to foreign currency exchange rate fluctuations.

Primary factors influencing the change in reported consolidated Selling, general and administrative expenses for the year ended

• an increase in general, administrative and other expenses, driven by higher wages and benefits, stock-based compensation 

expense and bonus compensation accruals, partially offset by benefits from Project Summit, as well as lower professional fees 
and bad debt expense;

• an increase in sales, marketing and account management expenses, driven by higher compensation expense, primarily 

reflecting increased wages and sales commissions, as well as increased marketing costs; and

• an increase of $10.1 million due to foreign currency exchange rate fluctuations. 

DEPRECIATION AND AMORTIZATION

Our depreciation and amortization charges result primarily from depreciation related to storage systems, which include racking 
structures, buildings, building and leasehold improvements and computer systems hardware and software. Amortization relates 
primarily to customer relationship intangible assets, contract fulfillment costs and data center lease-based intangible assets. Both 
depreciation and amortization are impacted by the timing of acquisitions.

Depreciation expense increased $17.5 million, or 3.9%, on a reported dollar basis for the year ended December 31, 2021 
compared to the year ended December 31, 2020. See Note 2.h. to Notes to Consolidated Financial Statements included in this 
Annual Report for additional information regarding the useful lives over which our property, plant and equipment is depreciated. 

Amortization expense increased $10.8 million, or 5.3%, on a reported dollar basis for the year ended December 31, 2021 
compared to the year ended December 31, 2020. 

ACQUISITION AND INTEGRATION COSTS

Acquisition and integration costs represent operating expenditures directly associated with the closing and integration activities of 
our business acquisitions that have closed, or are highly probable of closing, and include (i) advisory, legal and professional fees to 
complete business acquisitions and (ii) costs to integrate acquired businesses into our existing operations, including move, 
severance, facility upgrade and system integration costs (collectively, "Acquisition and Integration Costs"). Acquisition and 
Integration Costs do not include costs associated with the formation of joint ventures or costs associated with the acquisition of 
customer relationships. Acquisition and Integration Costs for the years ended December 31, 2021, 2020 and 2019 was 
approximately $12.8 million, $0.0 million and $13.3 million, respectively.

FOREIGN CURRENCY TRANSACTION (GAINS) LOSSES, NET 

We recorded net foreign currency transaction gains of $15.8 million in the year ended December 31, 2021, based on period-end 
exchange rates. These gains resulted primarily from the impact of changes in the exchange rate of the Euro and the British pound 
sterling against the United States dollar compared to December 31, 2020 on our intercompany balances with and between certain 
of our subsidiaries.

as of May 18, 2021, of one of our wholly owned Netherlands subsidiaries, for which we had value-added tax liability exposure that 
was recorded in 2019, partially offset by (c) losses on our equity method investments. Other, net for the year ended December 31, 
2020 consists primarily of (a) changes in the estimated value of our mandatorily redeemable noncontrolling interests and (b) losses 
on our equity method investments.

PROVISION (BENEFIT) FOR INCOME TAXES

Our effective tax rates for the years ended December 31, 2021 and 2020 were 28.0% and 7.9%, respectively. Our effective tax rate 
is subject to variability in the future due to, among other items: (1) changes in the mix of income between our QRSs and our TRSs, 
as well as among the jurisdictions in which we operate; (2) tax law changes; (3) volatility in foreign exchange gains and losses; (4) 
the timing of the establishment and reversal of tax reserves; and (5) our ability to utilize net operating losses that we generate.

The primary reconciling items between the federal statutory tax rate of 21.0% and our overall effective tax rate were:

YEAR ENDED DECEMBER 31,

2021

The benefit derived from the dividends paid deduction of $8.2 million 
which was offset by (1) the impact of differences in the tax rates at 
which our foreign earnings are subject to, resulting in a tax provision 
of $9.9 million, and (2) foreign withholding taxes of $23.7 million, 
which were either paid during the year or accrued, for the deferred tax 
liability for the U.S. tax impact of undistributed earnings of foreign 
TRSs that are no longer intended to be permanently reinvested 
outside the United States. 

2020
The benefit derived from the dividends paid deduction of $60.4 million 
and the impact of differences in the tax rates at which our foreign 
earnings are subject to, resulting in a tax provision of $9.5 million.

As a REIT, we are entitled to a deduction for dividends paid, resulting in a substantial reduction of federal income tax expense. As a 
REIT, substantially all of our income tax expense will be incurred based on the earnings generated by our foreign subsidiaries and 
our domestic TRSs.

We are subject to income taxes in the United States and numerous foreign jurisdictions. We are subject to examination by various 
tax authorities in jurisdictions in which we have business operations or a taxable presence. We regularly assess the likelihood of 
additional assessments by tax authorities and provide for these matters as appropriate. Although we believe our tax estimates are 
appropriate, the final determination of tax audits and any related litigation could result in changes in our estimates.

Primary factors influencing the change in revenue and Adjusted EBITDA Margin in our Global RIM Business segment for the year 
ended December 31, 2021 compared to the year ended December 31, 2020 include the following:

• organic storage rental revenue growth driven by revenue management and volume;

• a 2.3% increase in global records management volume (excluding acquisitions, global records management volume increased 

0.2%);

• organic service revenue growth mainly driven by increased traditional service activity levels, particularly in regions where 

governments have lifted or eased COVID-19 related restrictions on our customers' non-essential business operations, and 
growth in our Global Digital Solutions and Secure IT Asset Disposition businesses;

• an increase in revenue of $54.6 million due to foreign currency exchange rate fluctuations; and

• a 100 basis point increase in Adjusted EBITDA Margin primarily driven by benefits from Project Summit, revenue management, 
ongoing cost containment measures and lower bad debt expense, partially offset by increases in compensation, benefits, sales 
commissions and rent expense.

• an increase in Adjusted EBITDA primarily driven by organic storage rental revenue growth; and

• a 330 basis point decrease in Adjusted EBITDA Margin reflecting a change in revenue mix due to lower margin project revenue 

during the period, which is expected to have a temporary impact on segment margins.

and

• a decrease in Adjusted EBITDA driven by higher wages, benefits and bonus compensation accruals, partially offset by benefits 
from Project Summit, decreased professional fees, ongoing cost containment measures and improved service revenue trends.

LIQUIDITY AND CAPITAL RESOURCES

GENERAL

We expect to meet our short-term and long-term cash flow requirements through cash generated from operations, cash on hand, 
borrowings under our Credit Agreement (as defined below) and proceeds from monetizing a small portion of our total industrial real 
estate assets, as well as other potential financings (such as the issuance of debt or equity). Our cash flow requirements, both in the 
near and long term, include, but are not limited to, capital expenditures, the repayment of outstanding debt, shareholder dividends, 
potential and pending business acquisitions and normal business operation needs. 

PROJECT SUMMIT

As disclosed above, in October 2019, we announced Project Summit. From the inception of Project Summit through December 31, 
2021, we have incurred approximately $450.0 million of Restructuring Charges related to Project Summit, primarily related to 
employee severance costs, internal costs associated with the development and implementation of Project Summit initiatives and 
professional fees. From the inception of Project Summit through December 31, 2021, we have also incurred approximately $33.8 
million of capital expenditures. As of December 31, 2021, we have completed Project Summit.

A. CASH FLOWS FROM OPERATING ACTIVITIES

For the year ended December 31, 2021, net cash flows provided by operating activities decreased by $228.8 million compared to 
the prior year period primarily due to a decrease in cash from working capital of $266.0 million, primarily related to the collections of 
accounts receivable and timing of accounts payable and accrued expenses, partially offset by an increase in net income (including 
non-cash charges) of $37.2 million.

B. CASH FLOWS FROM INVESTING ACTIVITIES

Our significant investing activities during the year ended December 31, 2021 are highlighted below:

• We paid cash for capital expenditures of $611.1 million. Additional details of our capital spending are included in the “Capital 

Expenditures” section below.

• We paid cash for acquisitions (net of cash acquired) of $204.0 million, primarily funded by borrowings under our Revolving Credit 

Facility. 

• We received $278.3 million in proceeds from sales of property, plant and equipment, primarily related to proceeds from sale and 
sale-leaseback transactions of 14 facilities in the United Kingdom and the United States during the second and fourth quarters of 
2021.

• We received $213.9 million in net proceeds from the IPM Divestment.

C. CASH FLOWS FROM FINANCING ACTIVITIES

Our significant financing activities for the year ended December 31, 2021 included:

• Net proceeds of $737.8 million associated with the issuance of the 5% Notes due 2032 (as defined below).

• Net payments of $192.3 million primarily associated with repayment of borrowings under the Revolving Credit Facility and the 

Accounts Receivable Securitization Program.

• Purchase of noncontrolling interest of $75.0 million.

CAPITAL EXPENDITURES

We present two categories of capital expenditures: (1) Growth Investment Capital Expenditures and (2) Recurring Capital 
Expenditures with the following sub-categories: (i) Data Center; (ii) Real Estate; (iii) Innovation and Other (for Growth Investment 
Capital Expenditures only); and (iv) Non-Real Estate (for Recurring Capital Expenditures only). 

GROWTH INVESTMENT CAPITAL EXPENDITURES:

of land and development of facilities) or capacity expansion in existing buildings.

• Real Estate: Expenditures primarily related to investments in land, buildings, building improvements, leasehold improvements 

and racking structures to grow our revenues or achieve operational efficiencies.

•

Innovation and Other: Discretionary capital expenditures for significant new products and services, restructuring (including 
Project Summit), and integration of acquisitions.

RECURRING CAPITAL EXPENDITURES:

• Real Estate: Expenditures primarily related to the replacement of components of real estate assets such as buildings, building 

improvements, leasehold improvements and racking structures.

• Non-Real Estate: Expenditures primarily related to the replacement of containers and shred bins, warehouse equipment, 

fixtures, computer hardware, or third-party or internally-developed software assets that support the maintenance of existing 
revenues or avoidance of an increase in costs.

CREDIT AGREEMENT

Our credit agreement (the "Credit Agreement") consists of a revolving credit facility (the “Revolving Credit Facility”) and a term loan 
(the “Term Loan A”). The Revolving Credit Facility enables IMI and certain of its United States and foreign subsidiaries to borrow in 
United States dollars and (subject to sublimits) a variety of other currencies (including Canadian dollars, British pounds sterling and 
Euros, among other currencies) in an aggregate outstanding amount not to exceed $1,750.0 million. Under the Credit Agreement, 
we have the option to request additional commitments of up to $1,260.0 million, in the form of term loans or through increased 
commitments under the Revolving Credit Facility, subject to the conditions specified in the Credit Agreement. The Credit Agreement 
is scheduled to mature on June 3, 2023, at which point all obligations become due. The original principal amount of the Term Loan 
A was $250.0 million and is to be paid in quarterly installments in an amount equal to $3.1 million per quarter, with the remaining 
balance due on June 3, 2023. 

IMI and the Guarantors guarantee all obligations under the Credit Agreement. The interest rate on borrowings under the Credit 
Agreement varies depending on our choice of interest rate and currency options, plus an applicable margin, which varies based on 
our consolidated leverage ratio. Additionally, the Credit Agreement requires the payment of a commitment fee on the unused 
portion of the Revolving Credit Facility, which fee ranges from between 0.25% to 0.4% based on our consolidated leverage ratio 
and fees associated with outstanding letters of credit. As of December 31, 2021, we had no outstanding borrowings under the 
Revolving Credit Facility and $203.1 million aggregate outstanding principal amount under the Term Loan A. At December 31, 
2021, we had various outstanding letters of credit totaling $3,039 under the Revolving Credit Facility. The amount available for 
borrowing under the Revolving Credit Facility as of December 31, 2021, which is based on IMI’s leverage ratio, the last 12 months' 
earnings before interest, taxes, depreciation and amortization and rent expense (“EBITDAR”), other adjustments as defined in the 
Credit Agreement and current external debt, was $1,747.0 million (which amount represents the maximum availability as of such 
date). Available borrowings under the Revolving Credit Facility are subject to compliance with our indenture covenants as 
discussed below. The average interest rate in effect under the Revolving Credit Facility and Term Loan A was 1.9% as of  
December 31, 2021.

Part II

IMI’s wholly owned subsidiary, Iron Mountain Information Management, LLC (“IMIM”), has an incremental term loan B with a 
principal amount of $700.0 million (the “Term Loan B”). The Term Loan B, which matures on January 2, 2026, was issued at 
99.75% of par. The Term Loan B holders benefit from the same security and guarantees as other borrowings under the Credit 
Agreement. The Term Loan B holders also benefit from the same affirmative and negative covenants as other borrowings under the 
Credit Agreement; however, the Term Loan B holders are not generally entitled to the benefits of the financial covenants under the 
Credit Agreement.

Principal payments on the Term Loan B are to be paid in quarterly installments of $1.8 million per quarter during the period June 
30, 2018 through December 31, 2025, with the balance due on January 2, 2026. The Term Loan B may be prepaid without penalty 
at any time. The Term Loan B bears interest at a rate of LIBOR plus 1.75%. As of December 31, 2021, we had $673.8 million 
aggregate outstanding principal amount under the Term Loan B. The interest rate in effect under Term Loan B as of December 31, 
2021 was 3.1%.

DECEMBER 2021 OFFERING

On December 28, 2021, Iron Mountain Information Management Services, Inc., one of our wholly owned subsidiaries, completed a 
private offering of $750.0 million in aggregate principal amount of the 5% Notes due 2032. The 5% Notes due 2032 were issued at 
100.000% of par. The total net proceeds of approximately $738.0 million from the issuance of the 5% Notes due 2032, after 
deducting the initial purchasers’ commissions, were used to finance the purchase price of the ITRenew Transaction, which closed 
on January 25, 2022, and to pay related fees and expenses. At December 31, 2021, the net proceeds from the 5% Notes due 
2032, were used to temporarily repay borrowings under our Revolving Credit Facility and Accounts Receivable Securitization 
Program and invest in money market funds. The 5% Notes due 2032 are fully and unconditionally guaranteed, on a senior basis, 
by IMI and the other Guarantors. 

UK BILATERAL REVOLVING CREDIT FACILITY

Iron Mountain (UK) PLC and Iron Mountain (UK) Data Centre Limited (collectively, the "UK Borrowers") have a 140.0 million British 
pounds sterling Revolving Credit Facility (the “UK Bilateral Facility”) with Barclays Bank PLC. The maximum amount permitted to 
be borrowed under the UK Bilateral Facility is 140.0 million British pounds sterling, and we have the option to request additional 
commitments of up to 125.0 million British pounds sterling, subject to the conditions specified in the UK Bilateral Facility. The UK 
Bilateral Facility is fully drawn. The UK Bilateral Facility is secured by certain properties in the United Kingdom. IMI and the 
Guarantors guarantee all obligations under the UK Bilateral Facility. The UK Bilateral Facility was originally scheduled to mature on 
September 23, 2022, at which point all obligations were to become due. 

On May 25, 2021, the UK Borrowers entered into an amendment to the UK Bilateral Facility with Barclays Bank PLC to (i) modify 
the interest rate from LIBOR plus 2.25% to LIBOR plus 2.0% (with flexibility built in for the expected transition away from LIBOR) 
and (ii) add an additional option to extend the maturity date by one year. After this amendment, the UK Bilateral Facility contains 
two one-year options that allow us to extend the maturity date beyond the September 23, 2022 expiration date, subject to certain 
conditions specified in the UK Bilateral Facility, including the lender's consent. On September 23, 2021, the UK Borrowers executed 
the one-year option to extend the maturity date to September 24, 2023.The interest rate in effect under the UK Bilateral Facility was 
2.1% as of December 31, 2021.  

ACCOUNTS RECEIVABLE SECURITIZATION PROGRAM

We participate in an accounts receivable securitization program (the “Accounts Receivable Securitization Program”) involving 
several of our wholly owned subsidiaries and certain financial institutions. Under the Accounts Receivable Securitization Program, 
certain of our subsidiaries sell substantially all of their United States accounts receivable balances to our wholly owned special 
purpose entities, Iron Mountain Receivables QRS, LLC and Iron Mountain Receivables TRS, LLC (the “Accounts Receivable 
Securitization Special Purpose Subsidiaries”). The Accounts Receivable Securitization Special Purpose Subsidiaries use the 
accounts receivable balances to collateralize loans obtained from certain financial institutions. The Accounts Receivable 
Securitization Special Purpose Subsidiaries are consolidated subsidiaries of IMI. IMIM retains the responsibility of servicing the 
accounts receivable balances pledged as collateral for the Accounts Receivable Securitization Program and IMI provides a 
performance guaranty. The maximum availability allowed is limited by eligible accounts receivable, as defined under the terms of 
the Accounts Receivable Securitization Program. 

On June 28, 2021, we entered into an amendment to the Accounts Receivable Securitization Program to extend the maturity date 
from July 30, 2021 to July 1, 2023, at which point all obligations become due. The interest rate under the amended Accounts 
Receivable Securitization Program is LIBOR plus 1.0%. As of December 31, 2021, the maximum amount available under the 
Accounts Receivable Securitization Program was $300.0 million. There were no amounts outstanding under the Accounts 
Receivable Securitization Program as of December 31, 2021. Commitment fees at a rate of 40 basis points are charged on 
amounts made available but not borrowed under the Accounts Receivable Securitization Program.

LETTERS OF CREDIT

Part II

As of December 31, 2021, we had outstanding letters of credit totaling $36,480, of which $3,039 reduce our borrowing capacity 
under the Revolving Credit Facility (as described above). The letters of credit expire at various dates between January 2022 and 
March 2025.

DEBT COVENANTS

The Credit Agreement (as defined in Note 7 to Notes of Consolidated Financial Statements included in this Annual Report), our 
bond indentures and other agreements governing our indebtedness contain certain restrictive financial and operating covenants, 
including covenants that restrict our ability to complete acquisitions, pay cash dividends, incur indebtedness, make investments, 
sell assets and take other specified corporate actions. The covenants do not contain a rating trigger. Therefore, a change in our 
debt rating would not trigger a default under the Credit Agreement, our bond indentures or other agreements governing our 
indebtedness. The Credit Agreement requires that we satisfy a fixed charge coverage ratio, a net total lease adjusted leverage ratio 
and a net secured debt lease adjusted leverage ratio on a quarterly basis and our bond indentures require that, among other 
things, we satisfy a leverage ratio (not lease adjusted) or a fixed charge coverage ratio (not lease adjusted), as a condition to taking 
actions such as paying dividends and incurring indebtedness.

The Credit Agreement uses EBITDAR-based calculations and the bond indentures use EBITDA-based calculations as the primary 
measures of financial performance for purposes of calculating leverage and fixed charge coverage ratios. The bond indenture 
EBITDA-based calculations include our consolidated subsidiaries, other than those we have designated as “Unrestricted 
Subsidiaries” as defined in the bond indentures. Generally, the Credit Agreement and the bond indentures use a trailing four fiscal 
quarter basis for purposes of the relevant calculations and require certain adjustments and exclusions for purposes of those 
calculations, which make the calculation of financial performance for purposes of those calculations under the Credit Agreement 
and bond indentures not directly comparable to Adjusted EBITDA as presented herein. These adjustments can be significant. For 
example, the calculation of financial performance under the Credit Agreement and certain of our bond indentures includes (subject 
to specified exceptions and caps) adjustments for non-cash charges and for expected benefits associated with (i) completed 
acquisitions, (ii) certain executed lease agreements associated with our data center business that have yet to commence, and (iii) 
restructuring and other strategic initiatives, such as Project Summit. The calculation of financial performance under our other bond 
indentures includes, for example, adjustments for non-cash charges and for expected benefits associated with (i) completed 
acquisitions, and (ii) events that are extraordinary, unusual or non-recurring, such as the COVID-19 pandemic.

Our leverage and fixed charge coverage ratios under the Credit Agreement as of December 31, 2021 are as follows:

Net total lease adjusted leverage ratio

Net secured debt lease adjusted leverage ratio

Fixed charge coverage ratio

DECEMBER 31, 2021 MAXIMUM/MINIMUM ALLOWABLE

5.3 

1.8 

2.4 

Maximum allowable of 6.5

Maximum allowable of 4.0

Minimum allowable of 1.5

We are in compliance with our leverage and fixed charge coverage ratios under the Credit Agreement, our bond indentures and 
other agreements governing our indebtedness as of December 31, 2021. Noncompliance with these leverage and fixed charge 
coverage ratios would have a material adverse effect on our financial condition and liquidity.

___________________________________________________________________________________________________

Our ability to pay interest on or to refinance our indebtedness depends on our future performance, working capital levels and 
capital structure, which are subject to general economic, financial, competitive, legislative, regulatory and other factors which may 
be beyond our control. There can be no assurance that we will generate sufficient cash flow from our operations or that future 
financings will be available on acceptable terms or in amounts sufficient to enable us to service or refinance our indebtedness or to 
make necessary capital expenditures.

DERIVATIVE INSTRUMENTS

INTEREST RATE SWAP AGREEMENTS

In March 2018, we entered into interest rate swap agreements to limit our exposure to changes in interest rates on a portion of our 
floating rate indebtedness. As of December 31, 2021, we had $350.0 million in notional value of interest rate swap agreements 
outstanding, which expire in March 2022. Under the interest rate swap agreements, we receive variable rate interest payments 
associated with the notional amount of each interest rate swap, based upon one-month LIBOR, in exchange for the payment of 
fixed interest rates as specified in the interest rate swap agreements. 

In July 2019, we entered into forward-starting interest rate swap agreements to limit our exposure to changes in interest rates on a 
portion of our floating rate indebtedness once our current interest rate swap agreements expire in March 2022. The forward-starting 
interest rate swap agreements have $350.0 million in notional value, commence in March 2022 and expire in March 2024. Under 
the swap agreements, we will receive variable rate interest payments based upon one-month LIBOR, in exchange for the payment 
of fixed interest rates as specified in the interest rate swap agreements.

Part II

We have designated these interest rate swap agreements, including the forward-starting interest rate swap agreements, as cash 
flow hedges. 

CROSS-CURRENCY SWAP AGREEMENTS

We enter into cross-currency swap agreements to hedge the variability of exchange rate impacts between the United States dollar 
and the Euro. The cross-currency swap agreements are designated as a hedge of net investment against certain of our Euro 
denominated subsidiaries and require an exchange of the notional amounts at maturity.

In August 2019, we entered into cross-currency swap agreements whereby we notionally exchanged approximately $110.0 million 
at an interest rate of 6.0% for approximately 99.1 million Euros at a weighted average interest rate of approximately 3.65%. These 
cross-currency swap agreements expire in August 2023.

In September 2020, we entered into cross-currency swap agreements whereby we notionally exchanged approximately $359.2 
million at an interest rate of 4.5% for approximately 300.0 million Euros at a weighted average interest rate of approximately 3.4%. 
These cross-currency swap agreements expire in February 2026.

See Note 6 to Notes to Consolidated Financial Statements included in this Annual Report for additional information on our 
derivative instruments. 

EQUITY FINANCING

In 2017, we entered into a Distribution Agreement with the Agents pursuant to which we could sell, from time to time, up to an 
aggregate sales price of $500.0 million of our common stock through the At The Market (ATM) Equity Program. On February 15, 
2022, the Distribution Agreement was terminated.  

During the quarter and year ended December 31, 2021, there were no shares of common stock sold under the At The Market 
(ATM) Equity Program. 

ACQUISITIONS  

See Note 3 to Notes to Consolidated Financial Statements included in this Annual Report for information regarding our 2021 
acquisitions.

INFOFORT ACQUISITION

On September 15, 2021, in order to further expand our records management operations in the Middle East and North Africa, we 
acquired Information Fort, LLC, a records and information management provider, for approximately $90.3 million.

FRANKFURT DATA CENTER ACQUISITION

On September 23, 2021, in order to further enhance our data center operations in Germany, we completed the acquisition of assets 
of a Frankfurt data center for approximately 77.9 million Euros (or approximately $91.3 million, based upon the exchange rate 
between the Euro and the United States dollar on the closing date of this acquisition).

OTHER 2021 ACQUISITIONS

In addition to the transactions noted above, during the year ended December 31, 2021, in order to enhance our existing operations 
in the United Kingdom and Indonesia and to expand our operations into Morocco, we completed the acquisition of two records 
management companies and one art storage company for total cash consideration of approximately $45.1 million. 

2022 ACQUISITION OF ITRENEW  

On January 25, 2022, we acquired an approximately 80% interest in Intercept Parent, Inc. ("ITRenew"), a company with asset 
lifecycle management operations primarily in the United States, for approximately $725.0 million (the “ITRenew Transaction”). The 
acquisition agreement also provides us the option to purchase, and the shareholders the option to sell, the remaining 
approximately 20% interest in ITRenew as follows: (i) approximately 16% on or after the second anniversary of the ITRenew 
Transaction and (ii) approximately 4% on or after the third anniversary of the ITRenew Transaction (collectively, the “Remaining 
Interest”), each at a purchase price to be determined based upon the achievement of certain performance metrics, but for no less 
than $200.0 million in total.

INVESTMENTS

Part II

See Note 5 to Notes to Consolidated Financial Statements included in this Annual Report for information regarding our joint 
ventures.

2021 NEWLY FORMED JOINT VENTURE

In April 2021, we closed on an agreement to form a joint venture (the "Web Werks JV") with the shareholders of Web Werks India 
Private Limited ("Web Werks"), a colocation data center provider in India. In connection with the formation of the Web Werks JV, we 
made an initial investment of approximately 3,750.0 million Indian rupees (or approximately $50.1 million, based upon the 
exchange rate between the United States dollar and Indian rupee as of the closing date of the initial investment) in exchange for a 
noncontrolling interest in the form of convertible preference shares in the Web Werks JV (the “Initial Web Werks JV Investment”). 
These shares are convertible into a to-be-determined amount of common shares based upon the achievement of EBITDA targets 
for the Web Werks JV's fiscal year ending March 31, 2022.

Under the terms of the Web Werks JV shareholder agreement, we are required to make additional investments over a period 
ending May 2023 totaling approximately 7,500.0 million Indian rupees (or approximately $100.0 million, based upon the exchange 
rate as of December 31, 2021 between the United States dollar and Indian rupee).

JOINT VENTURE SUMMARY

The following joint ventures are accounted for as equity method investments and are presented as a component of Other within

Part II

ITEM 7A. QUANTITATIVE AND QUALITATIVE 
DISCLOSURES ABOUT MARKET RISK.

CREDIT RISK

Financial instruments that potentially subject us to credit risk consist principally of cash and cash equivalents (including money 
market funds and time deposits) and accounts receivable. The only significant concentrations of liquid investments as of 
December 31, 2021 relate to cash and cash equivalents held in money market funds with four “Triple A” rated money market funds 
and time deposits with one global bank. As per our risk management investment policy, we limit exposure to concentration of credit 
risk by limiting the amount invested in any one mutual fund to a maximum of 1% of the fund's total assets or in any one financial 
institution to a maximum of $75.0 million. As of December 31, 2021, our cash and cash equivalents balance, including restricted 
cash, was $255.8 million.

INTEREST RATE RISK

Given the recurring nature of our revenues and the long-term nature of our asset base, we have the ability and the preference to 
use long-term, fixed interest rate debt to finance our business at attractive rates, thereby helping to preserve our long-term returns 
on invested capital. Occasionally, we may use interest rate swaps as a tool to maintain our targeted level of fixed rate debt.

As of December 31, 2021, we had $973.3 million of variable rate debt outstanding with a weighted average variable interest rate of 
approximately 3.3%, and $8,391.2 million of fixed rate debt outstanding. As of December 31, 2021, approximately 90% of our total 
debt outstanding was fixed. If the weighted average variable interest rate on our variable rate debt had increased by 1%, our net 
income for the year ended December 31, 2021 would have been reduced by approximately $12.2 million. 

See Note 6 to Notes to Consolidated Financial Statements included in this Annual Report for a discussion on our interest rate 
swaps and Note 7 to Notes to Consolidated Financial Statements included in this Annual Report for a discussion of our long-term 
indebtedness, including the fair values of such indebtedness as of December 31, 2021.

CURRENCY RISK 

Our international investments may be subject to risks and uncertainties related to fluctuations in currency valuation. Our reporting 
currency is the United States dollar. However, our international revenues and expenses are generated in the currencies of the 
countries in which we operate, primarily the British pound sterling, Euro, Canadian dollar, Brazilian real and the Australian dollar. 
Declines in the value of the local currencies in which we are paid relative to the United States dollar will cause revenues in United 
States dollar terms to decrease and dollar-denominated liabilities to increase in local currency.

The impact of currency fluctuations on our earnings is mitigated by the fact that most operating and other expenses are also 
incurred and paid in the local currency. We also have several intercompany obligations between our foreign subsidiaries and IMI 
and our United States-based subsidiaries. In addition, our foreign subsidiaries and IME also have intercompany obligations 
between them. These intercompany obligations are primarily denominated in the local currency of the foreign subsidiary.

We have adopted and implemented a number of strategies to mitigate the risks associated with fluctuations in foreign currency 
exchange rates. One strategy is to finance certain of our international subsidiaries with debt that is denominated in local currencies, 
thereby providing a natural hedge. In determining the amount of any such financing, we take into account local tax considerations, 
among other factors. Another strategy we utilize is for IMI or IMIM, a wholly-owned subsidiary of IMI, to borrow in foreign currencies 
to hedge our intercompany financing activities. In addition, on occasion, we enter into currency swaps to temporarily or 
permanently hedge an overseas investment, such as a major acquisition, to lock in certain transaction economics. We have 
implemented these strategies for our foreign investments in the United Kingdom, Canada, Australia, Latin America and continental 
Europe. IM UK has financed a portion of its capital needs through the issuance in British pounds sterling of the GBP Notes due 
2025. Our Australian business has financed a portion of its capital needs through direct borrowings in Australian dollars under the 
AUD Term Loan. This creates a tax efficient natural currency hedge. 

We have entered into cross-currency swap agreements to hedge the variability of exchange rate impacts between the United 
States dollar and the Euro. These cross-currency swap agreements are designated as a hedge of net investment against certain of 
our Euro denominated subsidiaries and require an exchange of the notional amounts at maturity. These cross-currency swaps are 
marked to market at the end of each reporting period and any changes in fair value are recorded as a component of Accumulated 
other comprehensive items, net. Unrealized gains are recognized as assets, which are recorded as a component of Other within 
Other assets, net, while unrecognized losses are recognized as liabilities, which are recorded as either a component of (i) Accrued 
expenses and other current liabilities or (ii) Other long-term liabilities in our Consolidated Balance Sheets. 

See Note 6 to Notes to Consolidated Financial Statements included in this Annual Report for a discussion on our cross-currency 
swap agreements.

58

IRON MOUNTAIN 2021 FORM 10-K

Table of Contents

Part II

As of and during the year ending December 31, 2021, we had no outstanding forward contracts. At the maturity of any forward 
contract, we may enter into a new forward contract to hedge movements in the underlying currencies. At the time of settlement, we 
either pay or receive the net settlement amount from any forward contract and recognize this amount in Other (income) expense, 
net in the accompanying statements of operations as a realized foreign exchange gain or loss. At the end of each month, we mark 
the outstanding forward contracts to market and record an unrealized foreign exchange gain or loss for the mark-to-market 
valuation. Historically, we have not designated any of the forward contracts we have entered as hedges.

The impact of devaluation or depreciating currency on an entity depends on the residual effect on the local economy and the ability 
of an entity to raise prices and/or reduce expenses. Due to our constantly changing currency exposure and the potential substantial 
volatility of currency exchange rates, we cannot predict the effect of exchange fluctuations on our business. The effect of a change 
in foreign currency exchange rates on our net investment in foreign subsidiaries is reflected in the “Accumulated Other 
Comprehensive Items, net” component of equity. A 10% depreciation in year-end 2021 functional currencies, relative to the United 
States dollar, would result in a reduction in our equity of approximately $300.0 million.

ITEM 9A. CONTROLS AND PROCEDURES. 

DISCLOSURE CONTROLS AND PROCEDURES

The term “disclosure controls and procedures” is defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act. These rules refer 
to the controls and other procedures of a company that are designed to ensure that information is recorded, processed, 
accumulated, summarized, communicated and reported to management, including its principal executive and principal financial 
officers, as appropriate to allow timely decisions regarding what is required to be disclosed by a company in the reports that it files 
under the Exchange Act. As of December 31, 2021 (the “Evaluation Date”), we carried out an evaluation, under the supervision and 
with the participation of our management, including our chief executive officer and chief financial officer, of the effectiveness of our 
disclosure controls and procedures. Based upon that evaluation, our chief executive officer and chief financial officer concluded 
that, as of the Evaluation Date, our disclosure controls and procedures are effective.

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER 
FINANCIAL REPORTING

Our management, with the participation of our principal executive officer and principal financial officer, is responsible for 
establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) of the 
Exchange Act. Our internal control system is designed to provide reasonable assurance to our management and board of directors 
regarding the preparation and fair presentation of published financial statements. Due to their 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 policies or procedures may deteriorate. Under the supervision and with the participation of our management, including our 
chief executive officer and chief financial officer, we conducted an evaluation of the effectiveness of our internal control over 
financial reporting based on the framework in Internal Control—Integrated Framework (2013) issued by the Committee of 
Sponsoring Organizations of the Treadway Commission. Based on this evaluation, our management concluded that our internal 
control over financial reporting was effective as of December 31, 2021.

The effectiveness of our internal control over financial reporting has been audited by Deloitte & Touche LLP, an independent 
registered public accounting firm, as stated in their report which is included in this Annual Report.

REPORT OF INDEPENDENT REGISTERED PUBLIC 
ACCOUNTING FIRM  

To the shareholders and the Board of Directors of Iron Mountain Incorporated

OPINION ON INTERNAL CONTROL OVER FINANCIAL REPORTING

We have audited the internal control over financial reporting of Iron Mountain Incorporated and subsidiaries (the “Company”) as of 
December 31, 2021, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of 
Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, 
effective internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control - 
Integrated Framework (2013) issued by COSO. 

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) 
(PCAOB), the consolidated financial statements as of and for the year ended December 31, 2021, of the Company and our report 
dated February 24, 2022, expressed an unqualified opinion on those financial statements. 

BASIS FOR OPINION

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment 
of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal 
Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial 
reporting based on our audit. 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 audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the 
audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material 
respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a 
material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed 
risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a 
reasonable basis for our opinion.

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 reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets 
of the company; (2) 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 of the company are 
being made only in accordance with authorizations of management and directors of the 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 the degree of compliance with the policies or procedures may deteriorate.

Our management, with the participation of our principal executive officer and principal financial officer, is responsible for 
establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) of the 
Exchange Act. Our internal control system is designed to provide reasonable assurance to our management and board of directors 
regarding the preparation and fair presentation of published financial statements.

There were no changes in our internal control over financial reporting (as defined in Rule 13a-15(f) of the Exchange Act) during the

ITEM 9B. OTHER INFORMATION.

Disclosure Pursuant to Section 13(r) of the Exchange Act

Section 219 of the Iran Threat Reduction and Syria Human Rights Act of 2012 and Section 13(r) of the Exchange Act require an 
issuer to disclose in its annual and quarterly reports whether it or any of its affiliates have knowingly engaged in certain activities, 
including specified activities or transactions relating to the Government of Iran (as defined in section 560.304 of title 31 of the Code 
of Federal Regulations) and to persons designated under Executive Order No. 13382 (70 Fed. Reg. 38567). As previously 
disclosed in our Quarterly Reports on Form 10-Q for the quarters ended March 31, 2020 and June 30, 2020 (the “2020 Quarterly 
Reports”) and in our Annual Report on Form 10-K for the year ended December 31, 2020 (the “2020 Annual Report”), during the 
first quarter of 2020, we determined that one of our non-U.S. subsidiaries provided limited hard copy record, electronic media (e.g., 
CD), box and container storage and handling services during such quarter, and in prior periods since the reporting requirement 
took effect, to at least one entity designated under Executive Order No. 13382 (the “Entity”) and one Government of Iran entity - 
both located outside of Iran. In each case, the customer relationship commenced at a time when U.S. sanctions law did not limit 
dealings with entities determined to be part of the Government of Iran or designated under Executive Order No. 13382 by non-U.S. 
entities owned or controlled by U.S. persons. Each relationship automatically continued from year to year without any affirmative 
step being taken by either party. During the second quarter of 2020, the non-U.S. subsidiary in question notified both entities of its 
decision to terminate those relationships. 

We also reported in the 2020 Quarterly Reports and 2020 Annual Report that we had notified the U.S. Department of the Treasury’s 
Office of Foreign Assets Control (“OFAC”) of these limited activities and initiated an internal investigation, and, during that 
investigation, we had identified two additional customer relationships between the subsidiary in question and entities designated 
under Executive Order No. 13382 and Executive Order No. 13224, neither of which was active and ongoing during the year ended 
December 31, 2020. We have been actively cooperating with OFAC in its review of this matter.

As we reported in our 2020 Annual Report, following the year ended December 31, 2020, we submitted a Final Notice of Voluntary 
Disclosure (“Final VSD”) with OFAC on January 14, 2021. The Final VSD included a detailed overview of our internal investigation 
and the remedial measures we have implemented or will be implementing to address the root causes of the potentially violative 
activity. The Final VSD findings showed that the potential violations were inadvertent. We will continue to cooperate fully with OFAC 
in its ongoing review of this matter. 

As we reported in our 2020 Quarterly Reports and our 2020 Annual Report, when the non-U.S. subsidiary terminated its 
relationship with the Entity during the second quarter of 2020, it also took steps to treat the property held in storage for the Entity as 
blocked property under regulations administered by OFAC, including by placing blocks and notices on the Entity’s account and 
instructing relevant employees of the non-U.S. subsidiary. However, as reported in our Quarterly Report for the quarter ended June 
30, 2021, notwithstanding such procedures, through a review process, the Company became aware in the second quarter of 2021 
that an employee of the non-U.S. subsidiary authorized the destruction of the Entity’s property. The Company conducted a review 
of the matter which resulted in remediation actions including the termination of the employee. The non-U.S. subsidiary in question 
did not receive any revenue in connection with this activity and, except for related communications, has not engaged in any other 
activity with the Entity during the period covered by this report. Consistent with the disclosure contained in the 2020 Annual Report, 
we do not intend to continue any activity involving the Entity.

On August 5, 2021, we submitted an Initial Notice of Voluntary Disclosure to OFAC regarding the destruction of the Entity’s 
property. We continue to investigate the matter and intend to submit a Final Notice of Voluntary Disclosure to OFAC once the 
investigation is complete. We will continue to cooperate fully with OFAC in its review of this matter.

We continue to enhance our internal processes and procedures designed to identify transactions associated with restricted parties, 
such as introducing a Global International Sanctions and Trade Law Policy and engaging a more comprehensive third-party 
screening provider. We are also supplementing our existing compliance training with the launch of global training on sanctions and 
restricted parties in the first quarter of 2021. We will continue to review and improve our programs and processes, as necessary or 
appropriate, to comply with all applicable sanctions laws and to comply with the disclosure requirements of Section 13(r) of the 
Exchange Act.

REPORT OF INDEPENDENT REGISTERED PUBLIC 
ACCOUNTING FIRM

To the shareholders and the Board of Directors of Iron Mountain Incorporated

OPINION ON THE FINANCIAL STATEMENTS

We have audited the accompanying consolidated balance sheets of Iron Mountain Incorporated and subsidiaries (the “Company”) 
as of December 31, 2021 and 2020, the related consolidated statements of operations, comprehensive income (loss), equity, and 
cash flows, for each of the three years in the period ended December 31, 2021, and the related notes and the schedule listed in the 
Index at Item 15 (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all 
material respects, the financial position of the Company as of December 31, 2021 and 2020, and the results of its operations and 
its cash flows for each of the three years in the period ended December 31, 2021, in conformity with accounting principles generally 
accepted in the United States of America.

We have also 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, 2021, based on criteria established in 
Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission 
and our report dated February 24, 2022, expressed an unqualified opinion on the Company’s internal control over financial 
reporting.

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.

CRITICAL AUDIT MATTER

The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was 
communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are 
material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The 
communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we 
are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the 
accounts or disclosures to which it relates.

GOODWILL - GLOBAL DATA CENTER REPORTING UNIT - REFER TO NOTE 2.K. TO THE 
FINANCIAL STATEMENTS 

CRITICAL AUDIT MATTER DESCRIPTION
The Company’s evaluation of goodwill for impairment involves the comparison of the fair value of each reporting unit to its carrying 
value. The Company determined the fair value of the Global Data Center reporting unit using a combined approach based on the 
present value of future cash flows (the “Discounted Cash Flow Model”) and market multiples (the “Market Approach”). The 
determination of the fair value using the Discounted Cash Flow Model requires management to make significant assumptions 
related to future revenue growth rates, operating margins, discount rates and capital expenditures. The determination of the fair 
value using the Market Approach requires management to make significant assumptions related to adjusted earnings before 
interest, taxes, depreciation and amortization (“Adjusted EBITDA”) multiples. Changes in economic and operating conditions 
impacting these assumptions or changes in multiples could result in goodwill impairments in future periods. The goodwill balance 
allocated to the Global Data Center reporting unit was $429 million as of October 1, 2021 (goodwill impairment testing date). The 
fair value of the Global Data Center reporting unit exceeded its carrying value as of the measurement date and, therefore, no 
impairment was recognized.

The Global Data Center reporting unit’s fair value exceeded its carrying value by less than 25%, accordingly, auditing the 
assumptions used in the goodwill impairment analysis for this reporting unit involved especially subjective judgment.

HOW THE CRITICAL AUDIT MATTER WAS ADDRESSED IN THE AUDIT
Our audit procedures related to future revenue growth rates, operating margins and capital expenditures (collectively, the 
“Forecast”), the selection of discount rates, and Adjusted EBITDA multiples for the Global Data Center reporting unit included the 
following, among others: 

• We evaluated management’s ability to accurately forecast by comparing actual results to management’s historical forecasts. 

• We evaluated the reasonableness of management’s Forecast by comparing it to (1) historical results, (2) internal 

communications to management and the Board of Directors, and (3) forecasted information included in Company press releases 
and industry reports of the Company and companies in its peer group.

• With the assistance of our fair value specialists, we evaluated the discount rates, including testing the underlying source 

information and the mathematical accuracy of the calculations, and developing a range of independent estimates and comparing 
those to the discount rates selected by management.

• With the assistance of our fair value specialists, we evaluated the Adjusted EBITDA multiples, including testing the underlying 
source information and mathematical accuracy of the calculations and comparing the multiples selected by management to its 
guideline companies.

• We tested the effectiveness of controls over the evaluation of goodwill for impairment, including those over the Forecast and the 

selection of the Adjusted EBITDA multiples and discount rates.

IRON MOUNTAIN INCORPORATED
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

DECEMBER 31, 2021
(In thousands, except share and per share data) 

1. NATURE OF BUSINESS

The accompanying financial statements represent the consolidated accounts of Iron Mountain Incorporated, a Delaware 
corporation (“IMI”), and its subsidiaries (“we” or “us”). We help organizations around the world protect their information, reduce 
storage costs, comply with regulations, facilitate corporate disaster recovery, and better use their information and information 
technology (“IT”) infrastructure for business advantages, regardless of its format, location or life cycle stage. We do this by storing 
physical records and data backup media, offering information management solutions, and providing data center space for 
enterprise-class colocation and opportunistic hyperscale deployments. We offer comprehensive records and information 
management services and data management services, along with the expertise and experience to address complex storage and 
information management challenges such as rising storage rental costs, legal and regulatory compliance, and disaster recovery 
requirements. We provide secure and reliable data center facilities to protect digital information and ensure the continued operation 
of our customers’ IT infrastructure, with reliable and flexible deployment options.

In March 2020, the World Health Organization declared a novel strain of coronavirus (“COVID-19”) a pandemic. The broader 
impacts of the COVID-19 pandemic on our financial position, results of operations and cash flows, including impacts to the 
estimates we use in the preparation of our financial statements, remain uncertain and difficult to predict as information continues to 
evolve, and the severity and duration of the pandemic, including new variants of COVID-19 that may emerge, remains unknown, as 
is our visibility of its effect on the markets we serve and our customers within those markets.

In October 2019, we announced a global program designed to better position us for future growth and achievement of our strategic 
objectives (“Project Summit”). As of December 31, 2021, we have completed Project Summit. See Note 13.

We have been organized and have operated as a real estate investment trust for United States federal income tax purposes 
(“REIT”) beginning with our taxable year ended December 31, 2014.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

A. PRINCIPLES OF CONSOLIDATION

The accompanying financial statements reflect our financial position, results of operations, comprehensive income (loss), equity 
and cash flows on a consolidated basis. All intercompany transactions and account balances have been eliminated.

B. USE OF ESTIMATES

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America 
(“GAAP”) requires us to make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, 
revenues and expenses, and related disclosure of contingent assets and liabilities at the date of the financial statements and for 
the period then ended. On an ongoing basis, we evaluate the estimates used. We base our estimates on historical experience, 
actuarial estimates, current conditions and various other assumptions that we believe to be reasonable under the circumstances. 
These estimates form the basis for making judgments about the carrying values of assets and liabilities and are not readily 
apparent from other sources. Actual results may differ from these estimates.

C. FOREIGN CURRENCY

Local currencies are the functional currencies for our operations outside the United States, with the exception of certain foreign 
holding companies, whose functional currency is the United States dollar. In those instances where the local currency is the 
functional currency, assets and liabilities are translated at period-end exchange rates, and revenues and expenses are translated 
at average exchange rates for the applicable period. See Note 2.q.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

D. CASH, CASH EQUIVALENTS AND RESTRICTED CASH

Cash and cash equivalents include cash on hand and cash invested in highly liquid short-term securities, which have remaining 
maturities at the date of purchase of less than 90 days. Cash and cash equivalents are carried at cost, which approximates fair 
value. 

E. ALLOWANCE FOR DOUBTFUL ACCOUNTS AND CREDIT MEMO RESERVES

We maintain an allowance for doubtful accounts and a credit memo reserve for estimated losses resulting from the potential 
inability of our customers to make required payments and potential disputes regarding billing and service issues.

In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update ("ASU") No. 2016-13, 
Financial Instruments-Credit Losses-Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”). ASU 2016-13 
changes how entities will measure credit losses on most financial assets. The standard eliminates the probable initial recognition of 
estimated losses and provides a forward-looking expected credit loss model for accounts receivable, loans and other financial 
instruments.

On January 1, 2020 we adopted ASU 2016-13 on a modified retrospective basis for all financial assets measured at amortized 
cost. The adoption of ASU 2016-13 did not result in a material impact on our consolidated financial statements. Under ASU 
2016-13, we calculate and monitor our allowance considering future potential economic and macroeconomic conditions and 
reasonable and supportable forecasts for expected future collectability of our outstanding receivables, in addition to considering our 
past loss experience, current and prior trends in our aged receivables and credit memo activity. Our considerations when 
calculating our allowance include, but are not limited to, the following: the location of our businesses, the composition of our 
customer base, our product and service lines, potential future economic unrest, and potential future macroeconomic factors, 
including natural disasters and any impacts associated with the COVID-19 pandemic. Continued adjustments will be made should 
there be any material change to reasonable and supportable forecasts that may impact our likelihood of collection, as it becomes 
evident. Our highly diverse global customer base, with no single customer accounting for more than approximately 1% of revenue 
during the years ended December 31, 2021, 2020 and 2019, limits our exposure to concentration of credit risk. Additionally, we 
write off uncollectible balances as circumstances warrant, generally, no later than one year past due.

Prior to our adoption of ASU 2016-13, we maintained an allowance for doubtful accounts for estimated losses resulting from the 
potential inability of our customers to make required payments and potential disputes regarding billing and service issues. When 
calculating the allowance, we considered our past loss experience, current and prior trends in our aged receivables and credit 
memo activity, current economic conditions, and specific circumstances of individual receivable balances. If the financial condition 
of our customers were to significantly change, resulting in a significant improvement or impairment of their ability to make 
payments, an adjustment of the allowance might have been required. 

A rollforward of allowance for doubtful accounts and credit memo reserves is as follows:

F. CONCENTRATIONS OF CREDIT RISK

Financial instruments that potentially subject us to credit risk consist principally of cash and cash equivalents (including money 
market funds and time deposits) and accounts receivable. The only significant concentrations of liquid investments as of 
December 31, 2021 and 2020 related to cash and cash equivalents. At December 31, 2021 and 2020, we had money market funds 
with four “Triple A” rated money market funds and time deposits with one global bank. As per our risk management investment 
policy, we limit exposure to concentration of credit risk by limiting the amount invested in any one mutual fund to a maximum of 1% 
of the fund's total assets or in any one financial institution to a maximum of $75,000. See Note 2.o.

G. PREPAID EXPENSES AND ACCRUED EXPENSES

There are no prepaid expenses with items greater than 5% of total current assets as of December 31, 2021 and 2020.

Accrued expenses and other current liabilities, with items greater than 5% of total current liabilities are shown separately, and

Minor maintenance costs are expensed as incurred. Major improvements which extend the life, increase the capacity or improve 
the safety or the efficiency of property owned are capitalized and depreciated. Major improvements to leased buildings are 
capitalized as leasehold improvements and depreciated.

We capitalize interest expense during the active construction period of major capital projects. Capitalized interest is added to the 
cost of the underlying assets and is amortized over the useful lives of the assets. During the years ended December 31, 2021, 
2020 and 2019, capitalized interest is as follows:

We develop various software applications for internal use. Computer software costs associated with internal use software are 
expensed as incurred until certain capitalization criteria are met. Third party consulting costs, as well as payroll and related costs 
for employees directly associated with, and devoting time to, the development of internal use computer software projects (to the 
extent time is spent directly on the project) are capitalized. Capitalization begins when the design stage of the application has been 
completed and it is probable that the project will be completed and used to perform the function intended. Capitalization ends when 
the asset is ready for its intended use. Depreciation begins when the software is placed in service. Computer software costs that 
are capitalized are periodically evaluated for impairment.

During the years ended December 31, 2021, 2020 and 2019, capitalized costs associated with the development of internal use 
computer software projects are as follows:

Entities are required to record the fair value of a liability for an asset retirement obligation in the period in which it is incurred. Asset 
retirement obligations represent the costs to replace or remove tangible long-lived assets required by law, regulatory rule or 
contractual agreement. Our asset retirement obligations are primarily the result of requirements under our facility lease agreements 
which generally have “return to original condition” clauses which would require us to remove or restore items such as shred pits, 
vaults, demising walls and office build-outs, among others. The significant assumptions used in estimating our aggregate asset 
retirement obligations are the timing of removals, the probability of a requirement to perform, estimated cost and associated 
expected inflation rates that are consistent with historical rates and credit-adjusted risk-free rates that approximate our incremental 
borrowing rate. Our asset retirement obligations at December 31, 2021 and 2020 were $36,493 and $34,537, respectively.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

I. LEASES

We lease facilities for certain warehouses, data centers and office space. We also have land leases, including those on which 
certain facilities are located. The majority of our leased facilities are classified as operating leases that, on average, have initial 
lease terms of five to 10 years, with one or more lease renewal options to extend the lease term. Our lease renewal option terms 
generally range from one to five years. The exercise of the lease renewal option is at our sole discretion and may contain fixed 
rent, fair market value based rent or Consumer Price Index rent escalation clauses. We include option periods in the lease term 
when our failure to renew the lease would result in an economic disincentive, thereby making it reasonably certain that we will 
renew the lease. We recognize straight line rental expense over the life of the lease and any fair market value or Consumer Price 
Index rent escalations are recognized as variable lease expense in the period in which the obligation is incurred. In addition, we 
lease certain vehicles and equipment. Vehicle and equipment leases typically have lease terms ranging from one to seven years. 

We account for all leases, both operating and financing, in accordance with Accounting Standards Codification ("ASC") Topic 842 
Leases, ("ASC 842"). Our accounting policy provides that leases with an initial term of 12 months or less will not be included within 
the lease right-of-use assets and lease liabilities recognized on our Consolidated Balance Sheets. We will continue to recognize 
the lease payments for those leases with an initial term of 12 months or less in our Consolidated Statements of Operations on a 
straight-line basis over the lease term.

The lease right-of-use assets and related lease liabilities are classified as either operating or financing. Lease right-of-use assets 
are calculated as the net present value of future payments plus any capitalized initial direct costs less any tenant improvements or 
lease incentives. Lease liabilities are calculated as the net present value of future payments. In calculating the present value of the 
lease payments, we utilize the rate stated in the lease (in the limited circumstances when such rate is explicitly stated) or, if no rate 
is explicitly stated, we utilize a rate that reflects our securitized incremental borrowing rate by geography for the lease term. We 
account for nonlease components (which include common area maintenance, taxes, and insurance) with the related lease 
component. Any variable nonlease components are not included within the lease right-of-use asset and lease liability on our 
Consolidated Balance Sheets, and instead, are reflected as an expense in the period incurred.

At January 1, 2019, we recognized the cumulative effect of initially applying ASC 842 as an adjustment to the opening balance of 
(Distributions in excess of earnings) Earnings in excess of distributions, resulting in an increase of approximately $5,800 to 
stockholders’ equity due to certain build to suit leases that were accounted for as financing leases under ASC 840, Leases, but are 
accounted for as operating leases under ASC 842. 

Operating and financing lease right-of-use assets and lease liabilities as of December 31, 2021 and 2020 are as follows:

(1) Estimated minimum future lease payments exclude variable common area maintenance charges, insurance and taxes. 

At December 31, 2021, we had 14 leases which we have signed but which have not yet commenced and are not included in our 
lease obligation table above. The total undiscounted minimum lease payments for these leases are approximately $456,700 and 
have lease terms that range from 10 to 25 years. Each of these leases is expected to commence during 2022. The largest of these 
leases is for a facility in the United Kingdom that is currently under construction. The exact terms of the lease will be determined 
upon the completion of building construction, which is expected to occur during late 2022. We expect the rent due in the first year 
of the lease to be approximately $5,000, and we expect the term of the lease to be approximately 25 years.

We review long-lived assets, including all finite-lived intangible assets, for impairment whenever events or changes in 
circumstances indicate the carrying amount of such assets may not be recoverable. Recoverability of these assets is determined 
by comparing the sum of the forecasted undiscounted net cash flows of the operation to which the assets relate to their carrying 
amount. The operations are generally distinguished by the business segment and geographic region in which they operate. If it is 
determined that we are unable to recover the carrying amount of the assets, the long-lived assets are written down, on a pro rata 
basis, to fair value. Fair value is determined based on discounted cash flows or appraised values, depending upon the nature of the 
assets. Long-lived assets, including finite-lived intangible assets, are amortized over their useful lives. Annually, or more frequently 
if events or circumstances warrant, we assess whether a change in the lives over which long-lived assets, including finite-lived 
intangible assets, are amortized is necessary.

approximately $164,000, of which 
(i) approximately $127,400 relates 
to the sale-leaseback transactions 
of five facilities in the United 
Kingdom during the second quarter 
of 2021 and (ii) approximately 
$36,600 relates to the sale and 
sale-leaseback transactions of nine 
facilities in the United States during 
the fourth quarter of 2021.  

• Gains associated with sale-
leaseback transactions of 
approximately $342,100, of which 
(i) approximately $265,600 relates 
to the sale-leaseback transactions 
of 14 facilities in the United States 
during the fourth quarter of 2020 
and (ii) approximately $76,400 
relates to the sale-leaseback 
transactions of two facilities in the 
United States during the third 
quarter of 2020.  

• Gains of approximately $24,100 
associated with the Frankfurt JV 
Transaction (as defined in Note 3).

• Gains associated with sale and sale-

leaseback transactions of 
approximately $67,800 in the United 
States.

• The sale of certain land and 

buildings of approximately $36,000 
in the United Kingdom.

Partially offset by losses from:

• The impairment charge on the 

assets associated with the select 
offerings within our Iron Mountain 
Iron Cloud portfolio and loss on the 
subsequent sale of certain IT 
infrastructure assets and rights to 
certain hardware and maintenance 
contracts used to deliver these 
offerings of approximately $25,000.

• The write-down of certain property,

(1)   The gains recognized associated with the sale and sale-leaseback transactions during the years ended December 31, 2021 and 2020 are part of our program to 
monetize a small portion of our industrial real estate assets. The terms for these leases are consistent with the terms of our lease portfolio, which are disclosed in 
Note 2.i.

K. GOODWILL AND OTHER INDEFINITE-LIVED INTANGIBLE ASSETS

Goodwill and intangible assets with indefinite lives are not amortized but are reviewed annually for impairment or more frequently if 
impairment indicators arise. Other than goodwill, we currently have no intangible assets that have indefinite lives and which are not 
amortized.

We have selected October 1 as our annual goodwill impairment review date. We have performed our annual goodwill impairment 
review as of October 1, 2021, 2020 and 2019. We concluded that as of October 1, 2021, 2020 and 2019, goodwill was not 
impaired. During the first quarter of 2020, as discussed in greater detail below, we concluded that we had a triggering event related 
to our Fine Arts reporting unit, requiring us to perform an interim goodwill impairment test. We concluded that the fair value of our 
Fine Arts reporting unit was less than its carrying value, and, therefore, we recorded a $23,000 impairment charge on the goodwill 
associated with this reporting unit during the first quarter of 2020.

The following is a discussion regarding (i) interim goodwill impairment review for our Fine Arts reporting unit during the first quarter 
of 2020 and (ii) the reporting units at which level we tested goodwill for impairment as of October 1, 2021 and 2020 and the 
composition of these reporting units at December 31, 2021 and 2020 (including the amount of goodwill associated with each 
reporting unit). When changes occur in the composition of one or more reporting units, the goodwill is reassigned to the reporting 
units affected based upon their relative fair values.

I. INTERIM GOODWILL IMPAIRMENT REVIEW - FINE ARTS, FIRST QUARTER OF 2020

During the first quarter of 2020, we concluded that we had a triggering event related to our Fine Arts reporting unit, requiring us to 
perform an interim goodwill impairment test. The primary factor contributing to our conclusion was the expected impact of the 
COVID-19 pandemic to this particular business and its customers and revenue sources, which caused us to believe it was more 
likely than not that the carrying value of our Fine Arts reporting unit exceeded its fair value. During the first quarter of 2020, we 
performed an interim goodwill impairment test for our Fine Arts reporting unit utilizing a discounted cash flow model, with updated 
assumptions on future revenues, operating expenditures and capital expenditures. We concluded that the fair value of our Fine Arts 
reporting unit was less than its carrying value, and, therefore, we recorded a $23,000 impairment charge on the goodwill 
associated with this reporting unit during the first quarter of 2020. Factors that may impact these assumptions include, but are not 
limited to: (i) our ability to maintain, or grow, storage and retail service revenues in this reporting unit in line with current 
expectations and (ii) our ability to manage our fixed and variable costs in this reporting unit in line with potential future revenue 
declines.

II. REPORTING UNITS AS OF OCTOBER 1, 2021 and 2020

Our reporting units at which level we performed our goodwill impairment analysis as of October 1, 2021 and 2020 were as follows: 

• North America Records and Information Management ("North 

• Asia Records and Information Management ("Asia RIM")

America RIM")

• Europe Records and Information Management ("Europe RIM")

• Latin America Records and Information Management ("Latin 

America RIM")

• Australia and New Zealand Records and Information 

Management ("ANZ RIM")

• Global Data Center

• Fine Arts

• Entertainment Services

We concluded that the goodwill associated with each of our reporting units was not impaired as of such date. There were no 
changes to the composition of our reporting units between October 1, 2021 and December 31, 2021 and between October 1, 2020 
and December 31, 2020.	

GOODWILL BY REPORTING UNIT AS OF DECEMBER 31, 2021 and 2020

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

Reporting unit valuations have generally been determined using a combined approach based on the present value of future cash 
flows (the “Discounted Cash Flow Model”) and market multiples (the “Market Approach”). 

The Discounted Cash Flow Model incorporates significant 
assumptions including future revenue growth rates, 
operating margins, discount rates and capital expenditures. 

The Market Approach requires us to make assumptions 
related to Adjusted EBITDA (as defined in Note 11) 
multiples. 

Changes in economic and operating conditions impacting these assumptions or changes in multiples could result in goodwill 
impairments in future periods. In conjunction with our annual goodwill impairment reviews, we reconcile the sum of the valuations 
of all of our reporting units to our market capitalization as of such dates.

The changes in the carrying value of goodwill attributable to each reportable operating segment for the years ended December 31, 
2021 and 2020 are as follows:

L. FINITE-LIVED INTANGIBLE ASSETS AND LIABILITIES

I. CUSTOMER RELATIONSHIP INTANGIBLE ASSETS
Customer relationship intangible assets, which are acquired through either business combinations or acquisitions of customer 
relationships, are amortized over periods ranging from 10 to 30 years. Customer relationship intangible assets are recorded based 
upon estimates of their fair value.

II. CUSTOMER INDUCEMENTS
Payments that are made to a customer’s current records management vendor in order to terminate the customer’s existing contract 
with that vendor (“Permanent Withdrawal Fees”), or direct payments to a customer for which no distinct benefit is received in return, 
are collectively referred to as "Customer Inducements". Customer Inducements are treated as a reduction of the transaction price 
over periods ranging from one to 10 years and are included in storage and service revenue in the accompanying Consolidated 
Statements of Operations. If the customer terminates its relationship with us, the unamortized carrying value of the Customer 
Inducement intangible asset is charged to revenue. However, in the event of such termination, we generally collect, and record as 
income, permanent removal fees that generally equal or exceed the amount of the unamortized Customer Inducement intangible 
asset.

III. DATA CENTER INTANGIBLE ASSETS AND LIABILITIES
Finite-lived intangible assets associated with our Global Data Center Business consist of the following:

DATA CENTER IN-PLACE LEASE INTANGIBLE ASSETS AND DATA CENTER TENANT RELATIONSHIP INTANGIBLE 
ASSETS
Data Center In-Place Lease Intangible Assets (“Data Center In-Place Leases”) and Data Center Tenant Relationship Intangible 
Assets (“Data Center Tenant Relationships”) reflect the value associated with acquiring a data center operation with active tenants 
as of the date of acquisition. The value of Data Center In-Place Leases is determined based upon an estimate of the economic 
costs (such as lost revenues, tenant improvement costs, commissions, legal expenses and other costs to acquire new data center 
leases) avoided by acquiring a data center operation with active tenants that would have otherwise been incurred if the data center 
operation was purchased vacant. Data Center In-Place Leases are amortized over the weighted average remaining term of the 
acquired data center leases. The value of Data Center Tenant Relationships is determined based upon an estimate of the 
economic costs avoided upon lease renewal of the acquired tenants, based upon expectations of lease renewal. Data Center 
Tenant Relationships are amortized over the weighted average remaining anticipated life of the relationship with the acquired 
tenant.

DATA CENTER ABOVE-MARKET AND BELOW-MARKET IN-PLACE LEASE INTANGIBLE ASSETS
We record Data Center Above-Market In-Place Lease Intangible Assets (“Data Center Above-Market Leases”) and Data Center 
Below-Market In-Place Lease Intangible Assets (“Data Center Below-Market Leases”) at the net present value of the difference 
between (i) the contractual amounts to be paid pursuant to each in-place lease and (ii) management’s estimate of the fair market 
lease rates for each corresponding in-place lease. Data Center Above-Market Leases and Data Center Below-Market Leases are 
amortized over the remaining non-cancellable term of the acquired in-place lease to storage revenue.

The gross carrying amount and accumulated amortization of our finite-lived intangible assets as of December 31, 2021 and 2020,

M. DEFERRED FINANCING COSTS

Deferred financing costs are amortized over the life of the related debt. If debt is retired early, the related unamortized deferred 
financing costs are written-off in the period the debt is retired to Other (income) expense, net. See Note 7.

N. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

Every derivative instrument is required to be recorded in the balance sheet as either an asset or a liability measured at its fair 
value. Periodically, we acquire derivative instruments that are intended to hedge either cash flows or values that are subject to 
foreign exchange or other market price risk and not for trading purposes. We have formally documented our hedging relationships, 
including identification of the hedging instruments and the hedged items, as well as our risk management objectives and strategies 
for undertaking each hedge transaction. Given the recurring nature of our revenues and the long-term nature of our asset base, we 
have the ability and the preference to use long-term, fixed interest rate debt to finance our business, thereby preserving our long-
term returns on invested capital. We may use interest rate swaps as a tool to maintain our targeted level of fixed rate debt. In 
addition, we may enter into cross-currency swaps to hedge the variability of exchange rates between the United States and our 
foreign subsidiaries, as well as interest rates. We may also use borrowings in foreign currencies, either obtained in the United 
States or by our foreign subsidiaries, to hedge foreign currency risk associated with our international investments. As of 
December 31, 2021 and 2020, none of our derivative instruments contained credit-risk related contingent features. See Note 6.

O. FAIR VALUE MEASUREMENTS

Entities are permitted under GAAP to elect to measure certain financial instruments and certain other items at either fair value or 
cost. We have elected the cost measurement option in all circumstances where we had an option. 

Our financial assets or liabilities that are carried at fair value are required to be measured using inputs from the three levels of the 
fair value hierarchy. A financial asset or liability’s classification within the hierarchy is determined based on the lowest level input 
that is significant to the fair value measurement. The three levels of the fair value hierarchy are as follows:

Level 1—Inputs are unadjusted quoted prices in active markets for identical assets or liabilities that we have the ability to access at 
the measurement date.

Level 2—Inputs include quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets 
or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (i.e., interest 
rates, yield curves, etc.), and inputs that are derived principally from or corroborated by observable market data by correlation or 
other means (market corroborated inputs).

Level 3—Unobservable inputs that reflect our assumptions about the assumptions that market participants would use in pricing the 
asset or liability. 

The assets and liabilities carried at fair value and measured on a recurring basis as of December 31, 2021 and 2020, respectively, 
are as follows:

(1) Money market funds and time deposits are measured based on quoted prices for similar assets and/or subsequent transactions.

(2) Certain trading securities are measured at fair value using quoted market prices.

(3) Certain trading securities are measured based on inputs other than quoted market prices that are observable.

(4) Derivative assets and liabilities include (i) interest rate swap agreements, including forward-starting interest rate swap agreements, to limit our exposure to changes 
in interest rates on a portion of our floating rate indebtedness and (ii) cross-currency swap agreements to hedge the variability of exchange rates impacts between 
the United States dollar and the Euro and certain of our Euro denominated subsidiaries. Our derivative financial instruments are measured using industry standard 
valuation models using market-based observable inputs, including interest rate curves, forward and spot prices for currencies and implied volatilities. Credit risk is 
also factored into the determination of the fair value of our derivative financial instruments. See Note 6 for additional information on our derivative financial 
instruments.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

We did not have any material items that are measured at fair value on a non-recurring basis for the years ended December 31, 
2021, 2020, and 2019, with the exception of: (i) the reporting units as presented in our goodwill impairment analysis (as disclosed 
in Note 2.k.); (ii) those acquired in acquisitions (as disclosed in Note 3); (iii) the redemption value of certain redeemable 
noncontrolling interests (as disclosed in Note 2.p.); and (iv) our initial investments in the Web Werks JV, the Frankfurt JV and the 
MakeSpace JV (each as defined in Note 5), all of which are based on Level 3 inputs.

The fair value of our long-term debt, which was determined based on either Level 1 inputs or Level 3 inputs, is disclosed in Note 7. 
Long-term debt is measured at cost in our Consolidated Balance Sheets as of December 31, 2021 and 2020. 

P. REDEEMABLE NONCONTROLLING INTERESTS

Certain unaffiliated third parties own noncontrolling interests in certain of our foreign consolidated subsidiaries. The underlying 
agreements between us and our noncontrolling interest shareholders for these subsidiaries contain provisions under which the 
noncontrolling interest shareholders can require us to purchase their respective interests in such subsidiaries at certain times and 
at a purchase price as stipulated in the underlying agreements (generally at fair value). These put options make these 
noncontrolling interests redeemable and, therefore, these noncontrolling interests are classified as temporary equity outside of 
stockholders’ equity. Redeemable noncontrolling interests are reported at the higher of their redemption value or the noncontrolling 
interest holders’ proportionate share of the underlying subsidiaries net carrying value. Increases or decreases in the redemption 
value of the noncontrolling interest are offset against Additional Paid-in Capital.

In 2018, one of our noncontrolling interest shareholders exercised its option to put its ownership interest back to us. Upon the 
exercise of the put option, this noncontrolling interest became mandatorily redeemable by us, and, therefore, was accounted for as 
a liability rather than a component of redeemable noncontrolling interests. In May 2021, we agreed to final settlement terms and 
paid the put option price for the noncontrolling interest shares.

R. REVENUES

Our revenues consist of storage rental revenues as well as service revenues and are reflected net of sales and value-added taxes. 
Storage rental revenues, which are considered a key driver of financial performance for the storage and information management 
services industry, consist primarily of recurring periodic rental charges related to the storage of materials or data (generally on a per 
unit basis) that are typically retained by customers for many years and revenues associated with our data center operations. 
Service revenues include charges for related service activities, the most significant of which include: (1) the handling of records, 
including the addition of new records, temporary removal of records from storage, refiling of removed records, customer termination 
and permanent removal fees, project revenues and courier operations, consisting primarily of the pickup and delivery of records 
upon customer request; (2) destruction services, consisting primarily of secure shredding of sensitive documents and the 
subsequent sale of shredded paper for recycling, the price of which can fluctuate from period to period; (3) digital solutions, 
including the scanning, imaging and document conversion services of active and inactive records, and consulting services; and (4) 
data center services, including set up, monitoring and support of our customers' assets which are protected in our data center 
facilities, and special project services, including data center fitout. 

We account for revenue in accordance with ASC 606, Revenue from Contracts with Customers (“ASC 606”). Customers are 
generally billed monthly based on contractually agreed-upon terms, and storage rental and service revenues are recognized in the 
month the respective storage rental or service is provided, in line with the transfer of control to the customer. When storage rental 
fees or services are billed in advance, amounts related to future storage rental or prepaid service contracts are accounted for as 
deferred revenue and recognized upon the transfer of control to the customer, generally ratably over the contract term. Customer 
contracts generally include promises to provide monthly recurring storage and related services that are essentially the same over 
time and have the same pattern of transfer of control to the customer; therefore, most performance obligations represent a promise 
to deliver a series of distinct services over time (as determined for purposes of ASC 606, a “series”). For those contracts that 
qualify as a series, we have a right to consideration from the customer in an amount that corresponds directly with the value of the 
underlying performance obligation transferred to the customer to date. This concept is known as "right to invoice” and we apply the 
“right to invoice” practical expedient to the majority of all revenues, with the exception of storage revenues in our Global Data 
Center Business (which are subject to leasing guidance). Additionally, each purchasing decision is fully in the control of the 
customer and; therefore, consideration beyond the current reporting period is variable and allocated to the specific period to which 
the consideration relates, which is consistent with the practical expedient.

Our Global Data Center Business features storage rental provided to the customer at contractually specified rates over a fixed 
contractual period. Storage rental revenue related to the storage component of our Global Data Center Business is recognized on a 
straight-line basis over the contract term in accordance with ASC 842. The revenue related to the service component of our Global 
Data Center Business is recognized in the period the related services are provided.

The costs associated with the initial movement of customer records into physical storage and certain commissions are considered 
costs to obtain or fulfill customer contracts (“Contract Fulfillment Costs”). The following describes our significant Contract Fulfillment 
Costs recognized under ASC 606:

INTAKE COSTS (AND ASSOCIATED DEFERRED REVENUE)
The costs of the initial intake of customer records into physical storage (“Intake Costs”) are deferred and amortized as a component 
of depreciation and amortization in our Consolidated Statements of Operations over three years, consistent with the transfer of the 
performance obligation to the customer to which the asset relates. In instances where such Intake Costs are billed to the customer, 
the associated revenue is deferred and recognized over the same three-year period. 

COMMISSIONS
Certain commission payments that are directly associated with the fulfillment of long-term contracts are capitalized and amortized 
as a component of depreciation and amortization in our Consolidated Statements of Operations over three years, consistent with 
the transfer of the performance obligation to the customer to which the asset relates. Certain direct commission payments 
associated with contracts with a duration of one year or less are expensed as incurred under the practical expedient which allows 
an entity to expense as incurred an incremental cost of obtaining a contract if the amortization period of the asset that the entity 
otherwise would have recognized is one year or less.

DATA CENTER LESSOR CONSIDERATIONS
Our Global Data Center Business features storage rental provided to customers at contractually specified rates over a fixed 
contractual period. Our data center revenue contracts are accounted for in accordance with ASC 842. ASC 842 provides a practical 
expedient which allows lessors to account for nonlease components (such as power and connectivity, in the case of our Global 
Data Center Business) with the related lease component if both the timing and pattern of transfer are the same for nonlease 
components and the lease component, and the lease component, if accounted for separately, would be classified as an operating 
lease. The single combined component is accounted for under ASC 842 if the lease component is the predominant component and 
is accounted for under ASC 606 if the nonlease components are the predominant components. We have elected to take this 
practical expedient.

S. STOCK-BASED COMPENSATION

We record stock-based compensation expense, utilizing the straight-line method, for the cost of stock options, restricted stock units 
(“RSUs”), performance units (“PUs”) and shares of stock issued under our employee stock purchase plan (“ESPP”) (together, 
"Employee Stock-Based Awards”).

For our Employee Stock-Based Awards made on or after February 20, 2019, we have included the following retirement provision: 

• Upon an employee’s retirement on or after attaining age 58, if the sum of (i) the award recipient’s age at retirement and (ii) the 

award recipient’s years of service with the company totals at least 70, the award recipient is entitled to continued vesting of any 
outstanding Employee Stock-Based Awards, provided that, for awards granted in the year of retirement, their retirement occurs 
on or after July 1 (the “Retirement Criteria”). 

• Accordingly, (i) grants of Employee Stock-Based Awards to an employee who has met the Retirement Criteria on or before the 
date of grant, or will meet the Retirement Criteria before July 1 of the year of the grant, will be expensed between the date of 
grant and July 1 of the grant year and (ii) grants of Employee Stock-Based Awards to employees who will meet the Retirement 
Criteria during the award’s normal vesting period will be expensed between the date of grant and the date upon which the award 
recipient meets the Retirement Criteria. 

• Stock options and RSUs granted to recipients who meet the Retirement Criteria will continue vesting on the original vesting 

schedule. If an employee retires and has met the Retirement Criteria, stock options generally will remain exercisable for up to 
three years or the original expiration date of the stock options, if earlier. PUs granted to recipients who meet the Retirement 
Criteria will continue to vest and be delivered in accordance with the original vesting schedule of the applicable PU award and 
remain subject to the same performance conditions.

The substantial majority of stock-based compensation expense for Employee Stock-Based Awards is included in Selling, general 
and administrative expenses in the accompanying Consolidated Statements of Operations.

STOCK OPTIONS
Options are generally granted with exercise prices equal to the market price of the stock on the date of grant; however, in certain 
instances, options are granted at prices greater than the market price of the stock on the date of grant. The substantial majority of 
options we issue become exercisable ratably over a period three years from the date of grant and have a contractual life of 10 
years from the date of grant, unless the holder’s employment is terminated sooner. Our non-employee directors are considered 
employees for purposes of our stock option plans and stock option reporting.

Our stock options outstanding at December 31, 2021 are based on the three-year vesting period (10 year contractual life) 
described above. 

Our equity compensation plans generally provide that, upon a vesting change in control (as defined in each plan), any unvested 
options and other awards granted thereunder shall vest immediately if an employee is terminated as a result of the change in 
control or terminates their own employment for good reason (as defined in each plan). On January 20, 2015, our stockholders 
approved the adoption of the Iron Mountain Incorporated 2014 Stock and Cash Incentive Plan, as amended (the "2014 Plan”). 

In May 2021, our stockholders approved an amendment to the 2014 Plan to (i) increase the number of shares of our common stock 
authorized for issuance thereunder by 8,000,000 from 12,750,000 to 20,750,000, (ii) extend the termination date of the 2014 Plan 
from May 24, 2027 to May 12, 2031, (iii) provide that, other than in specified circumstances, no equity-based award will vest before 
the first anniversary of the date of grant and (iv) provide that dividends and dividend equivalents are not paid with respect to stock 
options or stock appreciation rights.

A total of 20,750,000 shares of common stock have been reserved for grants of options and other rights under our various stock 
incentive plans, including the 2014 Plan. The number of shares available for grant under our various stock incentive plans, not 
including the ESPP, at December 31, 2021 was 9,055,756.

The weighted average fair value of stock options granted in 2021, 2020 and 2019 was $3.23, $2.35 and $3.58 per share, 
respectively. These values were estimated on the date of grant using the Black-Scholes option pricing model. The weighted 
average assumptions used for grants in the years ended December 31, 2021, 2020 and 2019 are as follows:

(1) Expected volatility is calculated utilizing daily historical volatility over a period that equates to the expected life of the option. 

(2) Risk-free interest rate is based on the United States Treasury interest rates whose term is consistent with the expected life (estimated period of time outstanding) of 

the stock options. 

(3) Expected dividend yield is considered in the option pricing model and represents our current annualized expected per share dividends over the current trade price of 

our common stock. 

(4) Expected life of the stock options granted is estimated using the historical exercise behavior of employees.

RESTRICTED STOCK UNITS
Our RSUs generally have a vesting period of three years from the date of grant. However, RSUs granted to our non-employee 
directors vest immediately upon grant. All RSUs accrue dividend equivalents associated with the underlying stock as we declare 
dividends. Dividends will generally be paid to holders of RSUs in cash upon the vesting date of the associated RSU and will be 
forfeited if the RSU does not vest. The fair value of RSUs is the excess of the market price of our common stock at the date of 
grant over the holder's purchase price (which is typically zero). 

The fair value of RSUs vested during the years ended December 31, 2021, 2020 and 2019, are as follows:

The PUs we issue vest based on our performance against predefined operational and share based targets. For awards granted in 
2019 and thereafter, the vesting is subject to a minimum level of return on invested capital (“ROIC”) in the third year of the 
performance period, and thereafter the number of PUs earned is based on (i) the revenue performance for each year averaged at 
the end of the three-year performance period, (ii) the revenue exit rate of new products in the last quarter of the three-year 
performance period and (iii) a relative TSR target. With respect to the PUs granted in 2019 and thereafter, the number of PUs 
earned may range from 0% to approximately 238% of the initial award.

PU grant. As detailed above, PUs granted are subject to the Retirement Criteria. PUs granted to recipients who meet the 
Retirement Criteria will continue to vest and be delivered in accordance with the original vesting schedule of the applicable PU 
award and remain subject to the same performance conditions. As a result, PUs are generally expensed over the three-year 
performance period.

All PUs accrue dividend equivalents associated with the underlying stock as we declare dividends. Dividends will generally be paid 
to holders of PUs in cash upon the settlement date of the associated PU and will be forfeited if the PU does not vest.

During the years ended December 31, 2021, 2020 and 2019, we issued 488,953, 425,777 and 380,856 PUs, respectively. We 
forecast the likelihood of achieving the predefined targets for our PUs in order to calculate the expected PUs to be earned. We 
record a compensation charge based on either the forecasted PUs to be earned (during the performance period) or the actual PUs 
earned (at the three-year anniversary of the grant date) over the vesting period for each of the awards. The fair value of PUs based 
on our performance against predefined targets is the excess of the market price of our common stock at the date of grant over the 
purchase price (which is typically zero). For PUs earned based on a market condition, we utilize a Monte Carlo simulation to fair 
value these awards at the date of grant, and such fair value is expensed over the three-year performance period. 

The fair value of earned PUs that vested during the years ended December 31, 2021, 2020 and 2019, is as follows:

EMPLOYEE STOCK PURCHASE PLAN
We offer an ESPP in which participation is available to substantially all United States and Canadian employees who meet certain 
service eligibility requirements. The ESPP provides for the purchase of our common stock by eligible employees through 
successive offering periods. We have historically had two six-month offering periods per year, the first of which generally runs from 
June 1 through November 30 and the second of which generally runs from December 1 through May 31. During each offering 
period, participating employees accumulate after-tax payroll contributions, up to a maximum of 15% of their compensation, to pay 
the purchase price at the end of the offering. Participating employees may withdraw from an offering before the purchase date and 
obtain a refund of the amounts withheld as payroll deductions. At the end of the offering period, outstanding options under the 
ESPP are exercised, and each employee’s accumulated contributions are used to purchase our common stock. The price for 
shares purchased under the ESPP is 95% of the fair market price at the end of the offering period, without a look-back feature. As 
a result, we do not recognize compensation expense for the ESPP shares purchased. In May 2021, our stockholders approved an 
amendment to the ESPP to increase the number of shares of Common Stock authorized for issuance thereunder by 1,000,000 
from 1,000,000 to 2,000,000. For the years ended December 31, 2021, 2020 and 2019, there were 112,297, 159,853 and 129,505 
shares, respectively, purchased under the ESPP. As of December 31, 2021, we have 1,103,990 shares available under the ESPP.
________________________________________________________

As of December 31, 2021, unrecognized compensation cost related to the unvested portion of our Employee Stock-Based Awards 
was $42,559 and is expected to be recognized over a weighted-average period of 1.9 years.

We issue shares of our common stock for the exercises of stock options, and the vesting of RSUs, PUs and shares of our common 
stock under our ESPP from unissued reserved shares.

T. ACQUISITION AND INTEGRATION COSTS

Acquisition and integration costs represent operating expenditures directly associated with the closing and integration activities of 
our business acquisitions that have closed, or are highly probable of closing, and include (i) advisory, legal and professional fees to 
complete business acquisitions and (ii) costs to integrate acquired businesses into our existing operations, including move, 
severance, facility upgrade and system integration costs (collectively, "Acquisition and Integration Costs"). Acquisition and 
Integration Costs do not include costs associated with the formation of joint ventures or costs associated with the acquisition of 
customer relationships. Acquisition and integration costs for the year ended December 31, 2021, 2020 and 2019 were $12,764, $0 
and $13,293, respectively.

V. INCOME TAXES

Accounting for income taxes requires the recognition of deferred tax assets and liabilities for the expected future tax consequences 
of temporary differences between the tax and financial reporting bases of assets and liabilities and for loss and credit 
carryforwards. Valuation allowances are provided when recovery of deferred tax assets does not meet the more likely than not 
standard as defined in GAAP. We have elected to recognize interest and penalties associated with uncertain tax positions as a 
component of the Provision (benefit) for income taxes in the accompanying Consolidated Statements of Operations.

W. INCOME (LOSS) PER SHARE—BASIC AND DILUTED

Basic income (loss) per common share is calculated by dividing income (loss) by the weighted average number of common shares 
outstanding. The calculation of diluted income (loss) per share is consistent with that of basic income (loss) per share but gives 
effect to all potential common shares (that is, securities such as stock options, RSUs, PUs, warrants or convertible securities) that 
were outstanding during the period, unless the effect is antidilutive. 

The calculation of basic and diluted income (loss) per share for the years ended December 31, 2021, 2020 and 2019 is as follows:

Income (loss) from continuing operations

X. NEW ACCOUNTING PRONOUNCEMENTS

RECENTLY ADOPTED ACCOUNTING PRONOUNCEMENTS

In December 2019, the Financial Accounting Standards Board (the "FASB") issued ASU No. 2019-12, Income Taxes (Topic 740) 
(“ASU 2019-12”). ASU 2019-12 simplifies the accounting for income taxes by removing certain exceptions for recognizing deferred 
taxes for investments, performing intra-period allocation and calculating income taxes in interim periods. ASU 2019-12 also adds 
guidance to reduce complexity in certain areas, including recognizing deferred taxes for tax goodwill and allocating taxes to 
members of a consolidated group. We adopted ASU 2019-12 on January 1, 2021. ASU 2019-12 did not have a material impact on 
our consolidated financial statements.

OTHER AS YET ADOPTED ACCOUNTING PRONOUNCEMENTS

In December 2021, the FASB issued ASU No. 2021-08, Business Combinations (Topic 805), Accounting for Contract Assets and 
Contract Liabilities from Contracts with Customers (“ASU 2021-08”). ASU 2021-08 requires that an entity recognize and measure 
contract assets and contract liabilities acquired in a business combination in accordance with ASU 2014-09 and for the related 
revenue contracts in accordance with ASU 2014-09 as if it had originated the contracts. ASU 2021-08 will be effective for us on 
January 1, 2023, with early adoption permitted. We are currently evaluating the impact ASU 2021-08 will have on our consolidated 
financial statements.

In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848) (“ASU 2020-04”). ASU 2020-04 provides 
optional expedients and exceptions for applying U.S.GAAP to contracts, hedging relationships, and other transactions, for a limited 
period of time, to ease the potential burden of recognizing the effects of reference rate reform on financial reporting. The 
amendments in ASU 2020-04 apply to contracts, hedging relationships and other transactions that reference the London Inter-Bank 
Offered Rate (“LIBOR”) or another reference rate expected to be discontinued due to the global transition away from LIBOR and 
certain other interbank offered rates. An entity may elect to apply the amendments provided by ASU 2020-04 beginning March 12, 
2020 through December 31, 2022. We are currently evaluating these amendments as they relate to our contracts, hedging 
relationships and other transactions that reference LIBOR, as well as the impact of ASU 2020-04 on our consolidated financial 
statements but do not expect the impact to be material. 

3. ACQUISITIONS

We account for acquisitions using the acquisition method of accounting, and, accordingly, the assets and liabilities acquired are 
recorded at their estimated fair values and the results of operations for each acquisition have been included in our consolidated 
results from their respective acquisition dates. 

A. ACQUISITIONS COMPLETED DURING THE YEAR ENDED DECEMBER 31, 2021  

On September 15, 2021, in order to further expand our records management operations in the Middle East and North Africa, we 
acquired Information Fort, LLC, a records and information management provider, for approximately $90,300.

On September 23, 2021, in order to further enhance our data center operations in Germany, we completed the acquisition of assets 
of a Frankfurt data center for approximately 77,900 Euros (or approximately $91,300, based upon the exchange rate between the 
Euro and the United States dollar on the closing date of this acquisition).

In addition to the transactions noted above, during the year ended December 31, 2021, in order to enhance our existing operations 
in the United Kingdom and Indonesia and to expand our operations into Morocco, we completed the acquisition of two records 
management companies and one art storage company for total cash consideration of approximately $45,100.

3. ACQUISITIONS (CONTINUED)

B. ACQUISITIONS COMPLETED DURING THE YEAR ENDED DECEMBER 31, 2020

Prior to January 9, 2020, we owned a 25% equity interest in OSG Records Management (Europe) Limited ("OSG"). On January 9, 
2020, we acquired the remaining 75% equity interest in OSG for cash consideration of approximately $95,500 (the "OSG 
Acquisition"). The OSG Acquisition enabled us to extend our Global RIM Business in Russia, Ukraine, Kazakhstan, Belarus, and 
Armenia. The results of OSG are fully consolidated within our consolidated financial statements from the closing date of the OSG 
Acquisition. In connection with the OSG Acquisition, our previously held 25% equity investment in OSG was remeasured to fair 
value at the closing date of the OSG Acquisition; as a result, we recorded a gain of approximately $10,000 during the first quarter of 
2020, which is included as a component of Other (income) expense, net on our Consolidated Statements of Operations. The fair 
value of the 25% equity investment in OSG was determined based on the purchase price of the OSG Acquisition. 

On February 17, 2020, in order to enhance our existing operations in the United Arab Emirates, we acquired Glenbeigh Records 
Management DWC-LLC, a storage and records management company, for total cash consideration of approximately $29,100.

C. ACQUISITIONS COMPLETED DURING THE YEAR ENDED DECEMBER 31, 2019

During the year ended December 31, 2019, in order to enhance our existing operations in the United States, Colombia, Germany, 
Hong Kong, Latvia, Slovakia, Switzerland, Thailand and the United Kingdom and to expand our operations into Bulgaria, we 
completed the acquisition of 10 storage and records management companies and one art storage company for total cash 
consideration of approximately $51,000. The individual purchase prices of these acquisitions ranged from approximately $700 to 
$12,500.

(1) Cash paid for acquisitions, net of cash acquired in our Consolidated Statement of Cash Flows includes contingent and other payments of $0, $512 and $7,267 for the 

years ended December 31, 2021, 2020 and 2019, respectively, related to acquisitions made in the years prior to 2021, 2020 and 2019, respectively.

(2) The weighted average lives of Customer Relationship Intangible Assets associated with acquisitions in 2021, 2020 and 2019 was 11 years, 14 years and 16 years, 

respectively.

(3) The weighted average lives of Data Center In-Place Leases associated with acquisitions in 2021 was five years.

(4) The weighted average lives of Data Center Tenant Relationships associated with acquisitions in 2021 was five years.

(5) The weighted average lives of Data Center Below-Market Leases associated with acquisitions in 2021 was four years.

Allocations of the purchase price for acquisitions are based on estimates of the fair value of the net assets acquired and are subject 
to adjustment upon the finalization of the purchase price allocations. The accounting for business combinations requires estimates 
and judgments regarding expectations for future cash flows of the acquired business, and the allocations of those cash flows to 
identifiable tangible and intangible assets, in determining the assets acquired and liabilities assumed. The fair values assigned to 
tangible and intangible assets acquired and liabilities assumed, including contingent consideration, are based on management’s 
best estimates and assumptions, as well as other information compiled by management, including valuations that utilize customary 
valuation procedures and techniques. The estimates and assumptions underlying the initial valuations are subject to the collection 
of information necessary to complete the valuations within the measurement periods, which are up to one year from the respective 
acquisition dates. The preliminary purchase price allocations that are not finalized as of December 31, 2021 relate to the final 
assessment of the fair values of intangible assets (primarily customer relationship intangible assets) and property, plant and 
equipment associated with the acquisitions we closed in 2021.

3. ACQUISITIONS (CONTINUED)
As the valuation of certain assets and liabilities for purposes of purchase price allocations are preliminary in nature, they are 
subject to adjustment as additional information is obtained about the facts and circumstances regarding these assets and liabilities 
that existed at the acquisition date. Any adjustments to our estimates of purchase price allocation will be made in the periods in 
which the adjustments are determined and the cumulative effect of such adjustments will be calculated as if the adjustments had 
been completed as of the acquisition dates. Adjustments recorded during the fourth quarter of 2021 and year ended December 31, 
2021 were not material to our balance sheet or results from operations.

4. DIVESTMENTS

INTELLECTUAL PROPERTY MANAGEMENT BUSINESS  
On June 7, 2021, we sold our Intellectual Property Management ("IPM") business, also known as our technology escrow services 
business, which we predominantly operated in the United States, for total gross consideration of approximately $215,400 (the “IPM 
Divestment”). As a result of the IPM Divestment, we recorded a gain on sale of approximately $179,000 to Other (income) expense, 
net, during the year ended December 31, 2021, the substantial majority of which was recorded during the second quarter of 2021, 
representing the excess of the fair value of the consideration received over the sum of the carrying value of the IPM business.

We have concluded that the IPM Divestment does not meet the criteria to be reported as discontinued operations in our 
consolidated financial statements, as our decision to divest this business does not represent a strategic shift that will have a major 
effect on our operations and financial results. Accordingly, the revenues and expenses associated with this business are presented 
as a component of operating income (loss) in our Consolidated Statements of Operations for the year ended December 31, 2021 
through the closing date of the IPM Divestment and for the years ended December 31, 2020 and 2019 and the cash flows 
associated with this business is presented as a component of cash flows from operations in our Consolidated Statements of Cash 
Flows for the year ended December 31, 2021 through the closing date of the IPM Divestment and for the years ended December 
31, 2020 and 2019.

IRON MOUNTAIN CONSUMER STORAGE 
In March 2019, we contributed our customer contracts and certain intellectual property and other assets used by us to operate our 
consumer storage business in the United States and Canada (the “IM Consumer Storage Assets”) and approximately $20,000 in 
cash (gross of certain transaction expenses) (the “Cash Contribution”) to a strategic partnership (the “MakeSpace JV”) established 
by us and MakeSpace Labs, Inc. (“MakeSpace”) pursuant to a transaction which closed on March 19, 2019 (the "Consumer 
Storage Transaction"). Upon the closing of the Consumer Storage Transaction, the MakeSpace JV owned (i) the IM Consumer 
Storage Assets, (ii) the Cash Contribution and (iii) the customer contracts, intellectual property and certain other assets used by 
MakeSpace to operate its consumer storage business in the United States. As part of the Consumer Storage Transaction, we 
received an initial equity interest of approximately 34% in the MakeSpace JV (the "MakeSpace Investment"). In connection with the 
Consumer Storage Transaction and the investment in the MakeSpace JV, we also entered into a storage and service agreement 
with the MakeSpace JV to provide certain storage and related services to the MakeSpace JV (see Note 12). 

We have concluded that the divestment of the IM Consumer Storage Assets in the Consumer Storage Transaction does not meet 
the criteria to be reported as discontinued operations in our consolidated financial statements, as our decision to divest this 
business does not represent a strategic shift that will have a major effect on our operations and financial results. Accordingly, the 
revenues and expenses associated with this business are presented as a component of Income (loss) from continuing operations 
in our Consolidated Statements of Operations for the year ended December 31, 2019 through the closing date of the Consumer 
Storage Transaction and the cash flows associated with this business are presented as a component of cash flows from continuing 
operations in our Consolidated Statements of Cash Flows for the year ended December 31, 2019 through the closing date of the 
Consumer Storage Transaction.

As a result of the Consumer Storage Transaction, we recorded a gain on sale of approximately $4,200 to Other (income) expense, 
net, in the first quarter of 2019, representing the excess of the fair value of the consideration received over the sum of (i) the 
carrying value of our consumer storage operations and (ii) the Cash Contribution.

5. INVESTMENTS
WEB WERKS JOINT VENTURE  

In April 2021, we closed on an agreement to form a joint venture (the "Web Werks JV") with the shareholders of Web Werks India 
Private Limited ("Web Werks"), a colocation data center provider in India. In connection with the formation of the Web Werks JV, we 
made an initial investment of approximately 3,750,000 Indian rupees (or approximately $50,100, based upon the exchange rate 
between the United States dollar and Indian rupee as of the closing date of the initial investment) in exchange for a noncontrolling 
interest in the form of convertible preference shares in the Web Werks JV (the “Initial Web Werks JV Investment”). These shares 
are convertible into a to-be-determined amount of common shares based upon the achievement of EBITDA targets for the Web 
Werks JV's fiscal year ending March 31, 2022.

Under the terms of the Web Werks JV shareholder agreement, we are required to make additional investments over a period 
ending May 2023 totaling approximately 7,500,000 Indian rupees (or approximately $100,000, based upon the exchange rate as of 
December 31, 2021 between the United States dollar and Indian rupee).  

FRANKFURT JOINT VENTURE  

In October 2020, we formed a joint venture (the “Frankfurt JV”) with AGC Equity Partners (“AGC”) to design and develop a 280,000 
square foot, 27 megawatt, hyperscale data center currently under development in Frankfurt, Germany (the “Frankfurt JV 
Transaction”). AGC acquired an 80% equity interest in the Frankfurt JV, while we retained a 20% equity interest (the "Frankfurt JV 
Investment"). The total cash consideration for the 80% equity interest sold to AGC was approximately $105,000. We received 
approximately $93,300 (gross of certain transaction expenses) upon the closing of the Frankfurt JV, and we are entitled to receive 
an additional approximately $11,700 upon the completion of development of the data center, which we expect to occur in the third 
quarter of 2022. In connection with the Frankfurt JV Transaction, we also entered into agreements whereby we will earn various 
fees, including property management and construction and development fees, for services we are providing to the Frankfurt JV. 

As a result of the Frankfurt JV Transaction, we recognized a gain during the year ended December 31, 2020 of approximately 
$24,100, representing the excess of the fair value of the consideration received over the carrying value of the assets, which 
consisted primarily of land and land development assets which were previously included within our Global Data Center Business 
segment. 

MAKESPACE JOINT VENTURE

In March 2019, we formed the MakeSpace JV. In the second quarter of 2020, we committed to participate in a round of equity 
funding for the MakeSpace JV whereby we contributed approximately $36,000 of the $45,000 being raised in installments between 
May 2020 through October 2021.  

JOINT VENTURE SUMMARY

The joint ventures, referred to above, are accounted for as equity method investments and are presented as a component of Other 
within Other assets, net in our Consolidated Balance Sheets. The carrying values and equity interests in our joint ventures at

6. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES 

Derivative instruments we are party to include: (i) interest rate swap agreements (which are designated as cash flow hedges), (ii) 
cross-currency swap agreements (which are designated as net investment hedges) and (iii) foreign exchange currency forward 
contracts (which are not designated as hedges).

INTEREST RATE SWAP AGREEMENTS DESIGNATED AS CASH FLOW HEDGES

In March 2018, we entered into interest rate swap agreements to limit our exposure to changes in interest rates on a portion of our 
floating rate indebtedness. As of December 31, 2021 and 2020, we had $350,000 in notional value of interest rate swap 
agreements outstanding, which expire in March 2022. Under the interest rate swap agreements, we receive variable rate interest 
payments associated with the notional amount of each interest rate swap, based upon one-month LIBOR, in exchange for the 
payment of fixed interest rates as specified in the interest rate swap agreements. 

In July 2019, we entered into forward-starting interest rate swap agreements to limit our exposure to changes in interest rates on a 
portion of our floating rate indebtedness once our current interest rate swap agreements expire in March 2022. The forward-starting 
interest rate swap agreements have $350,000 in notional value, commence in March 2022 and expire in March 2024. Under the 
swap agreements, we will receive variable rate interest payments based upon one-month LIBOR, in exchange for the payment of 
fixed interest rates as specified in the interest rate swap agreements.

We have designated these interest rate swap agreements, including the forward-starting interest rate swap agreements, as cash 
flow hedges. Unrealized gains are recognized as assets, while unrealized losses are recognized as liabilities. 

CROSS-CURRENCY SWAP AGREEMENTS DESIGNATED AS A HEDGE OF NET 
INVESTMENT

In August 2019, we entered into cross-currency swap agreements to hedge the variability of exchange rate impacts between the 
United States dollar and the Euro. Under the terms of the cross-currency swap agreements we notionally exchanged approximately 
$110,000 at an interest rate of 6.0% for approximately 99,055 Euros at a weighted average interest rate of approximately 3.65%. 
These cross-currency swap agreements expire in August 2023 (“August 2023 Cross Currency Swap Agreements”).

In September 2020, we entered into cross-currency swap agreements to hedge the variability of exchange rates impacts between 
the United States dollar and the Euro. Under the terms of the cross-currency swap agreements, we notionally exchanged 
approximately $359,200 at an interest rate of 4.5% for approximately 300,000 Euros at a weighted average interest rate of 
approximately 3.4%. These cross-currency swap agreements expire in February 2026 (“February 2026 Cross Currency Swap 
Agreements”).

We have designated these cross-currency swap agreements as hedge of net investments against certain of our Euro denominated 
subsidiaries and they require an exchange of the notional amounts at maturity. These cross-currency swap agreements are marked 
to market at each reporting period, representing the fair values of the cross-currency swap agreements, and any changes in fair 
value are recognized as a component of Accumulated other comprehensive items, net. Unrealized gains are recognized as assets 
while unrealized losses are recognized as liabilities.

FOREIGN EXCHANGE CURRENCY FORWARD CONTRACTS NOT DESIGNATED AS 
HEDGING INSTRUMENTS 

On occasion, we enter into forward contracts to hedge our exposures associated with certain foreign currencies. We have not 
designated any of these forward contracts as hedges. Our policy is to record the fair value of each derivative instrument on a gross 
basis. As of December 31, 2021 and 2020, we had no outstanding forward contracts.

EURO NOTES DESIGNATED AS A HEDGE OF NET INVESTMENT 

Prior to their redemption in August 2020, we designated a portion of our Euro Notes as a hedge of net investment of certain of our 
Euro denominated subsidiaries. From January 1, 2020 through the date of redemption and for the year ended December 31, 2019 
we designated, on average, 300,000 and 284,986 Euros, respectively, of our Euro Notes as a hedge of net investment of certain of 
our Euro denominated subsidiaries. As a result, we recorded the following foreign exchange gains (losses) related to the change in 
fair value of such debt due to currency translation adjustments as a component of Accumulated other comprehensive items, net:

A. CREDIT AGREEMENT

Our credit agreement (the "Credit Agreement") consists of a revolving credit facility (the “Revolving Credit Facility”) and a term loan 
(the “Term Loan A”). The Revolving Credit Facility enables IMI and certain of its United States and foreign subsidiaries to borrow in 
United States dollars and (subject to sublimits) a variety of other currencies (including Canadian dollars, British pounds sterling and 
Euros, among other currencies) in an aggregate outstanding amount not to exceed $1,750,000. Under the Credit Agreement, we 
have the option to request additional commitments of up to $1,260,000, in the form of term loans or through increased 
commitments under the Revolving Credit Facility, subject to the conditions specified in the Credit Agreement. The Credit Agreement 
is scheduled to mature on June 3, 2023, at which point all obligations become due. The original principal amount of the Term Loan 
A was $250,000 and is to be paid in quarterly installments in an amount equal to $3,125 per quarter, with the remaining balance 
due on June 3, 2023. IMI and the Guarantors guarantee all obligations under the Credit Agreement. The interest rate on borrowings 
under the Credit Agreement varies depending on our choice of interest rate and currency options, plus an applicable margin, which 
varies based on our consolidated leverage ratio. Additionally, the Credit Agreement requires the payment of a commitment fee on 
the unused portion of the Revolving Credit Facility, which fee ranges from between 0.25% to 0.4% based on our consolidated 
leverage ratio and fees associated with outstanding letters of credit. As of December 31, 2021, we had no outstanding borrowings 
under the Revolving Credit Facility and $203,125 aggregate outstanding principal amount under the Term Loan A. At December 31, 
2021, we had various outstanding letters of credit totaling $3,039 under the Revolving Credit Facility. The remaining amount 
available for borrowing under the Revolving Credit Facility as of December 31, 2021, which is based on IMI’s leverage ratio, the 
last 12 months' earnings before interest, taxes, depreciation and amortization and rent expense (“EBITDAR”), other adjustments as 
defined in the Credit Agreement and current external debt, was $1,746,961 (which amount represents the maximum availability as 
of such date). Available borrowings under the Revolving Credit Facility are subject to compliance with our indenture covenants as 
discussed below. The average interest rate in effect under the Revolving Credit Facility and Term Loan A was 1.9% as of both 
December 31, 2021 and 2020.

principal amount of $700,000 (the “Term Loan B”). The Term Loan B, which matures on January 2, 2026, was issued at 99.75% of 
par. The Term Loan B holders benefit from the same security and guarantees as other borrowings under the Credit Agreement. The 
Term Loan B holders also benefit from the same affirmative and negative covenants as other borrowings under the Credit 
Agreement; however, the Term Loan B holders are not generally entitled to the benefits of the financial covenants under the Credit 
Agreement.

Principal payments on the Term Loan B are to be paid in quarterly installments of $1,750 per quarter during the period June 30, 
2018 through December 31, 2025, with the balance due on January 2, 2026. The Term Loan B may be prepaid without penalty at 
any time. The Term Loan B bears interest at a rate of LIBOR plus 1.75%. As of December 31, 2021, we had $673,750 aggregate 
outstanding principal amount under the Term Loan B. The interest rate in effect under Term Loan B as of December 31, 2021 and 
2020 was 3.1% and 1.9%, respectively.

C. AUSTRALIAN DOLLAR TERM LOAN

Iron Mountain Australia Group Pty, Ltd. (“IM Australia”), a wholly owned subsidiary of IMI, has an AUD term loan with an original 
principal balance of 350,000 Australian dollars (“AUD Term Loan”). All indebtedness associated with the AUD Term Loan was 
issued at 99% of par. Principal payments on the AUD Term Loan are to be paid in quarterly installments in an aggregate amount of 
8,750 Australian dollars per year. The AUD Term Loan bears interest at BBSY (an Australian benchmark variable interest rate) plus 
3.875%. The AUD Term Loan is scheduled to mature on September 22, 2022, at which point all obligations become due. The full 
amount of the AUD Term Loan is classified within the current portion of long-term debt in our Consolidated Balance Sheet as of 
December 31, 2021.

As of December 31, 2021, we had 307,813 Australian dollars ($223,530 based upon the 
exchange rate between the United States dollar and the Australian dollar as of 
December 31, 2021) outstanding on the AUD Term Loan. As of December 31, 2020, we 
had 316,563 Australian dollars ($244,014 based upon the exchange rate between the 
United States dollar and the Australian dollar as of December 31, 2020) outstanding on 
the AUD Term Loan. The interest rate in effect under the AUD Term Loan was 4.0% and

 D. UK BILATERAL REVOLVING CREDIT FACILITY 

IM UK and Iron Mountain (UK) Data Centre Limited has a 140,000 British pounds 
sterling Revolving Credit Facility (the “UK Bilateral Facility”) with Barclays Bank PLC. 
The maximum amount permitted to be borrowed under the UK Bilateral Facility is 
140,000 British pounds sterling, and we have the option to request additional 
commitments of up to 125,000 British pounds sterling, subject to the conditions 
specified in the UK Bilateral Facility. The UK Bilateral Facility is fully drawn. The UK 
Bilateral Facility is secured by certain properties in the United Kingdom. IMI and the 
Guarantors guarantee all obligations under the UK Bilateral Facility. 

On May 25, 2021, Iron Mountain (UK) PLC and Iron Mountain (UK) Data Centre Limited 
(collectively, the "UK Borrowers") entered into an amendment to the UK Bilateral Facility 
with Barclays Bank PLC to (i) modify the interest rate from LIBOR plus 2.25% to LIBOR 
plus 2.0% (with flexibility built in for the expected transition away from LIBOR) and (ii) 
add an additional option to extend the maturity date by one year. After this amendment, 
the UK Bilateral Facility contains two one-year options that allow us to extend the 
maturity date beyond the September 23, 2022 expiration date, subject to certain 
conditions specified in the UK Bilateral Facility, including the lender's consent. On 
September 23, 2021, the UK Borrowers executed the one-year option to extend the 
maturity date to September 24, 2023.The interest rate in effect under the UK Bilateral 
Facility was 2.1% and 2.3% as of December 31, 2021 and 2020, respectively.

E. ACCOUNTS RECEIVABLE SECURITIZATION PROGRAM 

We participate in an accounts receivable securitization program (the “Accounts Receivable Securitization Program”) involving 
several of our wholly owned subsidiaries and certain financial institutions. Under the Accounts Receivable Securitization Program, 
certain of our subsidiaries sell substantially all of their United States accounts receivable balances to our wholly owned special 
purpose entities, Iron Mountain Receivables QRS, LLC and Iron Mountain Receivables TRS, LLC (the “Accounts Receivable 
Securitization Special Purpose Subsidiaries”). The Accounts Receivable Securitization Special Purpose Subsidiaries use the 
accounts receivable balances to collateralize loans obtained from certain financial institutions. The Accounts Receivable 
Securitization Special Purpose Subsidiaries are consolidated subsidiaries of IMI. The Accounts Receivable Securitization Program 
is accounted for as a collateralized financing activity, rather than a sale of assets, and therefore: (i) accounts receivable balances 
pledged as collateral are presented as assets and borrowings are presented as liabilities on our Consolidated Balance Sheets, (ii) 
our Consolidated Statements of Operations reflect the associated charges for bad debt expense related to pledged accounts 
receivable (a component of selling, general and administrative expenses) and reductions to revenue due to billing and service 
related credit memos issued to customers and related reserves, as well as interest expense associated with the collateralized 
borrowings and (iii) receipts from customers related to the underlying accounts receivable are reflected as operating cash flows and 
borrowings and repayments under the collateralized loans are reflected as financing cash flows within our Consolidated Statements 
of Cash Flows. IMIM retains the responsibility of servicing the accounts receivable balances pledged as collateral for the Accounts 
Receivable Securitization Program and IMI provides a performance guaranty. The maximum availability allowed is limited by 
eligible accounts receivable, as defined under the terms of the Accounts Receivable Securitization Program. 

On June 28, 2021, we entered into an amendment to the Accounts Receivable 
Securitization Program to extend the maturity date from July 30, 2021 to July 1, 2023, 
at which point all obligations become due. The interest rate under the amended 
Accounts Receivable Securitization Program is LIBOR plus 1.0%. The full amount 
outstanding under the Accounts Receivable Securitization Program is classified within 
current portion of long-term debt at December 31, 2020 in our Condensed 
Consolidated Balance Sheets. There were no other changes to the terms of the 
Accounts Receivable Securitization Program.

F. CASH POOLING

Certain of our subsidiaries participate in cash pooling arrangements (the “Cash Pools”) to help manage global liquidity 
requirements. Under the Cash Pools, cash deposited by participating subsidiaries with certain financial institutions are pledged as 
security against the debit balances of other participating subsidiaries, and legal rights of offset are provided and, therefore, 
amounts are presented in our Consolidated Balance Sheets on a net basis. Each subsidiary receives interest on the cash balances 
held on deposit or pays interest on its debit balances based on an applicable rate as defined in the Cash Pools.

We utilize two separate Cash Pools with Bank Mendes Gans (“BMG”), an independently operated wholly owned subsidiary of ING 
Group, one of which we utilize to manage global liquidity requirements for our qualified REIT subsidiaries (the “BMG QRS Cash 
Pool”) and the other for our taxable REIT subsidiaries (the “BMG TRS Cash Pool”). We have executed overdraft facility agreements 
for the BMG QRS Cash Pool and BMG TRS Cash Pool, each in an amount not to exceed $10,000. Each overdraft facility permits 
us to cover a temporary net debit position in the applicable pool.

7. DEBT (CONTINUED) 

During the third quarter of 2021, certain of our subsidiaries in the Asia Pacific region began to participate in two cash pooling 
arrangements with JP Morgan Chase Bank, N.A. (“JPM”), one of which we utilize to manage global liquidity requirements for our 
QRSs in the Asia Pacific region (the “JPM QRS Cash Pool") and the other for our TRSs in the Asia Pacific region (the "JPM TRS 
Cash Pool") (collectively, the “JPM Cash Pools”). We have executed overdraft facility agreements for the JPM QRS Cash Pool and 
the JPM TRS Cash Pool in amounts not to exceed $12,000 and $10,000, respectively. Each overdraft facility permits us to cover a 
temporary net debit position in the applicable pool. 

The approximate amount of the net cash position, gross position and outstanding debit balances for each of our cash pools as of 
December 31, 2021 and 2020 were as follows:

G. LETTERS OF CREDIT

As of December 31, 2021, we had outstanding letters of credit totaling $36,480, of which $3,039 reduce our borrowing capacity 
under the Revolving Credit Facility (as described above). The letters of credit expire at various dates between January 2022 and 
March 2025.

H. DEBT COVENANTS

The Credit Agreement, our bond indentures and other agreements governing our indebtedness contain certain restrictive financial 
and operating covenants, including covenants that restrict our ability to complete acquisitions, pay cash dividends, incur 
indebtedness, make investments, sell assets and take other specified corporate actions. The covenants do not contain a rating 
trigger. Therefore, a change in our debt rating would not trigger a default under the Credit Agreement, our bond indentures or other 
agreements governing our indebtedness. The Credit Agreement requires that we satisfy a fixed charge coverage ratio, a net total 
lease adjusted leverage ratio and a net secured debt lease adjusted leverage ratio on a quarterly basis and our bond indentures 
require that, among other things, we satisfy a leverage ratio (not lease adjusted) or a fixed charge coverage ratio (not lease 
adjusted), as a condition to taking actions such as paying dividends and incurring indebtedness. 

The Credit Agreement uses EBITDAR-based calculations and the bond indentures use EBITDA-based calculations as the primary 
measures of financial performance for purposes of calculating leverage and fixed charge coverage ratios. The bond indenture 
EBITDA-based calculations include our consolidated subsidiaries, other than those we have designated as “Unrestricted 
Subsidiaries” as defined in the bond indentures. Generally, the Credit Agreement and the bond indentures use a trailing four fiscal 
quarter basis for purposes of the relevant calculations and require certain adjustments and exclusions for purposes of those 
calculations, which make the calculation of financial performance for purposes of those calculations under the Credit Agreement 
and bond indentures not directly comparable to Adjusted EBITDA as presented herein. We are in compliance with our leverage and 
fixed charge coverage ratios under the Credit Agreement, our bond indentures and other agreements governing our indebtedness 
as of December 31, 2021 and 2020. Noncompliance with these leverage and fixed charge coverage ratios would have a material 
adverse effect on our financial condition.

B. SELF-INSURED LIABILITIES

We are self-insured up to certain limits for costs associated with workers’ compensation claims, vehicle accidents, property and 
general business liabilities, and benefits paid under employee healthcare and short-term disability programs. At December 31, 
2021 and 2020, there were $46,797 and $47,959, respectively, of self-insurance accruals reflected in Accrued expenses on our 
Consolidated Balance Sheets. The measurement of these costs requires the consideration of historical cost experience and 
judgments about the present and expected levels of cost per claim. We account for these costs primarily through actuarial 
methods, which develop estimates of the undiscounted liability for claims incurred, including those claims incurred but not reported. 
These methods provide estimates of future claim costs based on claims incurred as of the balance sheet date.

associated with such litigation is covered by various commercial liability insurance policies purchased by us and, in limited cases, 
indemnification from third parties. Our policy is to establish reserves for loss contingencies when the losses are both probable and 
reasonably estimable. We record legal costs associated with loss contingencies as expenses in the period in which they are 
incurred. While the outcome of litigation is inherently uncertain, we do not believe any current litigation will have a material adverse 
effect on our consolidated financial condition, results of operations or cash flows. We have estimated a reasonably possible range 
for all loss contingencies and believe it is reasonably possible that we could incur aggregate losses in addition to amounts currently 
accrued for all matters up to an additional $25,000 over the next several years. 

9. STOCKHOLDERS’ EQUITY MATTERS

Our board of directors has adopted a dividend policy under which we have paid, and in the future intend to pay, quarterly cash 
dividends on our common stock. The amount and timing of future dividends will continue to be subject to the approval of our board 
of directors, in its sole discretion, and to applicable legal requirements.

In 2019, 2020 and 2021, our board of directors declared the following dividends:

9. STOCKHOLDERS’ EQUITY MATTERS (CONTINUED) 

During the years ended December 31, 2021, 2020 and 2019, we declared dividends in an aggregate and per share amount, based 
on the weighted average number of common shares outstanding during each respective year, as follows:

For federal income tax purposes, distributions to our stockholders are generally treated as nonqualified ordinary dividends 
(potentially eligible for the lower effective tax rates available for “qualified REIT dividends”), qualified ordinary dividends or return of 
capital. The United States Internal Revenue Service requires historical C corporation earnings and profits to be distributed prior to 
any REIT distributions, which may affect the character of each distribution to our stockholders, including whether and to what extent 
each distribution is characterized as a qualified or nonqualified ordinary dividend. In addition, certain of our distributions qualify as 
capital gain distributions. For the years ended December 31, 2021, 2020, and 2019, the dividends we paid on our common shares 
were classified as follows:

Nonqualified ordinary dividends

Dividends paid during the years ended December 31, 2021, 2020, and 2019 which were classified as qualified ordinary dividends 
for federal income tax purposes primarily related to the distribution of historical C corporation earnings and profits related to certain 
acquisitions completed during the years ended December 31, 2021, 2020, and 2019. In 2021, the percentage of our dividend that 
was classified as a capital gain was 21.8% and was primarily related to the sale of land and buildings in the United States and the 
United Kingdom. In 2020, the percentage of our dividend that was classified as a capital gain was 49.5% and primarily related to 
the sale of land and buildings in the United States. In 2019, the percentage of our dividend that was classified as a capital gain was 
14.7% and primarily related to the sale of land and buildings in the United Kingdom. 

10. INCOME TAXES

We have been organized and have operated as a REIT effective beginning with our taxable year that ended on December 31, 
2014. As a REIT, we are generally permitted to deduct from our federal taxable income the dividends we pay to our stockholders. 
The income represented by such dividends is not subject to federal taxation at the entity level but is taxed, if at all, at the 
stockholder level. The income of our domestic taxable REIT subsidiaries (“TRSs”), which hold our domestic operations that may not 
be REIT-compliant as currently operated and structured, is subject, as applicable, to federal and state corporate income tax. In 
addition, we and our subsidiaries continue to be subject to foreign income taxes in other jurisdictions in which we have business 
operations or a taxable presence, regardless of whether assets are held or operations are conducted through subsidiaries 
disregarded for federal income tax purposes or TRSs. We will also be subject to a separate corporate income tax on any gains 
recognized on the sale or disposition of any asset previously owned by a C corporation during a five-year period after the date we 
first owned the asset as a REIT asset that are attributable to “built-in gains” with respect to that asset on that date. We will also be 
subject to a built-in gains tax on our depreciation recapture recognized into income as a result of accounting method changes in 
connection with our acquisition activities. If we fail to remain qualified for taxation as a REIT, we will be subject to federal income 
tax at regular corporate income tax rates. Even if we remain qualified for taxation as a REIT, we may be subject to some federal, 
state, local and foreign taxes on our income and property in addition to taxes owed with respect to our TRS operations. In 
particular, while state income tax regimes often parallel the federal income tax regime for REITs, many states do not completely 
follow federal rules and some do not follow them at all.

effective tax rate is subject to variability in the future due to, among other items: (1) changes in the mix of income between our 
qualified REIT subsidiaries (“QRSs”) and our TRSs, as well as among the jurisdictions in which we operate; (2) tax law changes; 
(3) volatility in foreign exchange gains and losses; (4) the timing of the establishment and reversal of tax reserves; and (5) our 
ability to utilize net operating losses that we generate.

10. INCOME TAXES (CONTINUED)

The primary reconciling items between the federal statutory tax rate of 21.0% and our overall effective tax rate were:

YEAR ENDED DECEMBER 31,

2020
The benefit derived from the dividends paid 
deduction of $60,378 and the impact of 
differences in the tax rates at which our 
foreign earnings are subject to, resulting in a 
tax provision of $9,472. 

2019
The benefit derived from the dividends paid 
deduction of $40,577 and the impact of 
differences in the tax rates at which our 
foreign earnings are subject to, resulting in a 
tax provision of $8,562.

2021
The benefit derived from the dividends paid 
deduction of $8,203 which was offset by (1) 
the impact of differences in the tax rates at 
which our foreign earnings are subject to, 
resulting in a tax provision of $9,856, and (2) 
foreign withholding taxes of $23,654, which 
were either paid during the year or accrued, 
for the deferred tax liability for the U.S. tax 
impact of undistributed earnings of foreign 
TRSs that are no longer intended to be 
permanently reinvested outside the United 
States.

As a REIT, we are entitled to a deduction for dividends paid, resulting in a substantial reduction of federal income tax expense. As a 
REIT, substantially all of our income tax expense will be incurred based on the earnings generated by our foreign subsidiaries and 
our domestic TRSs. 

Following our conversion to a REIT in 2014, we concluded that it was not our intent to reinvest our current and future undistributed 
earnings of our foreign subsidiaries indefinitely outside the United States. As of December 31, 2016, we concluded that it is our 
intent to indefinitely reinvest our current and future undistributed earnings of certain of our unconverted foreign TRSs outside the 
United States. During 2021, as a result of the enactment of a tax law and the closing of various acquisitions, we reassessed this 
intention and concluded that it is no longer our intention to reinvest our undistributed earnings of our foreign TRSs indefinitely 
outside the United States. As a REIT, future repatriation of incremental undistributed earnings of our foreign subsidiaries will not be 
subject to federal or state income tax, with the exception of foreign withholding taxes. However, such future repatriations may 
require distributions to our stockholders in accordance with REIT distribution rules, and any such distribution may then be taxable, 
as appropriate, at the stockholder level. We expect to provide for foreign withholding taxes on the current and future earnings of all 
of our foreign subsidiaries as the result of such reassessment.

The evaluation of an uncertain tax position is a two-step process. The first step is a recognition process whereby we determine 
whether it is more likely than not that a tax position will be sustained upon examination, including resolution of any related appeals 
or litigation processes, based on the technical merits of the position. The second step is a measurement process whereby a tax 
position that meets the more likely than not recognition threshold is calculated to determine the amount of benefit to recognize in 
the financial statements. The tax position is measured as the largest amount of benefit that is greater than 50% likely of being 
realized upon ultimate settlement.

We have elected to recognize interest and penalties associated with uncertain tax positions as a component of the provision 
(benefit) for income taxes in the accompanying Consolidated Statements of Operations. We recorded an increase of $823 and 
$1,780 for gross interest and penalties for the years ended December 31, 2021 and 2019, respectively. We recorded a decrease of 
$1,499 for gross interest and penalties for the year ended December 31, 2020. We had $6,805 and $6,212 accrued for the 
payment of interest and penalties as of December 31, 2021 and 2020, respectively.

A summary of tax years that remain subject to examination by major tax jurisdictions is as follows:

10. INCOME TAXES (CONTINUED) 

The normal statute of limitations for United States federal tax purposes is three years from the date the tax return is filed; however, 
the statute of limitations may remain open for periods longer than three years in instances where a federal tax examination is in 
progress. The 2020, 2019 and 2018 tax years remain subject to examination for United States federal tax purposes as well as net 
operating loss carryforwards utilized in these years. The normal statute of limitations for state purposes is between three to five 
years. However, certain of our state statute of limitations remain open for periods longer than this when audits are in progress.

We are subject to income taxes in the United States and numerous foreign jurisdictions. We are subject to examination by various 
tax authorities in jurisdictions in which we have business operations or a taxable presence. We regularly assess the likelihood of 
additional assessments by tax authorities and provide for these matters as appropriate. As of December 31, 2021, we had $27,772 
of reserves related to uncertain tax positions, of which $24,627 and $3,145 is included in other long-term liabilities and deferred 
income taxes, respectively, in the accompanying Consolidated Balance Sheet. As of December 31, 2020, we had $25,969 of 
reserves related to uncertain tax positions, of which $23,402 and $2,567 is included in other long-term liabilities and deferred 
income taxes, respectively, in the accompanying Consolidated Balance Sheet. Although we believe our tax estimates are 
appropriate, the final determination of tax audits and any related litigation could result in changes in our estimates.

A rollforward of unrecognized tax benefits is as follows:

Gross tax contingencies—December 31, 2018

Gross additions based on tax positions related to the current year

Gross additions for tax positions of prior years

Gross reductions for tax positions of prior years

Lapses of statutes

The reversal of these reserves of $27,772 as of December 31, 2021 will be recorded as a reduction of our income tax provision, if 
sustained. We believe that it is reasonably possible that an amount up to approximately $5,364 of our unrecognized tax positions 
may be recognized by the end of 2022 as a result of a lapse of statute of limitations or upon closing and settling significant audits in 
various worldwide jurisdictions.

11. SEGMENT INFORMATION (CONTINUED)

The accounting policies of the reportable segments are the same as those described in Note 2. Adjusted EBITDA for each segment 
is defined as income (loss) from continuing operations before interest expense, net, provision (benefit) for income taxes, 
depreciation and amortization (inclusive of our share of Adjusted EBITDA from our unconsolidated joint ventures), and excluding 
certain items we do not believe to be indicative of our core operating results, specifically: 

EXCLUDED

• Acquisition and Integration Costs

• Other (income) expense, net

• Restructuring Charges

•

•

Intangible impairments

(Gain) loss on disposal/write-down of property, plant and 
equipment, net (including real estate)

• Stock-based compensation expense

• COVID-19 Costs (as defined below)

Internally, we use Adjusted EBITDA as the basis for evaluating the performance of, and allocated resources to, our operating 
segments.

A reconciliation of Income (Loss) from Continuing Operations to Adjusted EBITDA on a consolidated basis for the years ended 
December 31, 2021, 2020 and 2019 is as follows:

12. RELATED PARTY TRANSACTIONS

In October 2020, in connection with the Frankfurt JV Transaction, we entered into agreements whereby we will earn various fees, 
including (i) special project revenue and (ii) property management and construction and development fees for services we are 
providing to the Frankfurt JV (the “Frankfurt JV Agreements”). Revenues and expenses associated with the Frankfurt JV 
Agreements are presented as a component of our Global Data Business segment. During the years ended December 31, 2021 and 
2020, we recognized revenue of approximately $19,600 and $400, respectively, associated with the Frankfurt JV Agreements.

In March 2019, in connection with the Consumer Storage Transaction and the MakeSpace Investment, we entered into a storage 
and service agreement with the MakeSpace JV to provide certain storage and related services to the MakeSpace JV (the 
"MakeSpace Agreement”). Revenues and expenses associated with the MakeSpace Agreement are presented as a component of 
our Global RIM Business segment. During the years ended December 31, 2021, 2020 and 2019, we recognized revenue of 
approximately $34,700, $33,600, and $22,500, respectively, associated with the MakeSpace Agreement. 

During the years ended December 31, 2021, 2020 and 2019, the Company had no other related party transactions.

13. PROJECT SUMMIT

In October 2019, we announced Project Summit, our global program designed to better position us for future growth and 
achievement of our strategic objectives. We expanded Project Summit during the first quarter of 2020 to include additional 
opportunities to streamline our business and operations, as well as accelerated the timing of certain opportunities previously 
identified. As of December 31, 2021, we have completed Project Summit. As a result of the program we have simplified our global 
structure, rebalanced resources to focus on higher growth areas, realigned our management structure to create a more dynamic, 
agile organization, made investments to enhance the customer experience and leveraged new technology solutions that enabled 
us to modernize our service delivery model and more efficiently utilize our fleet, labor and real estate.  

The implementation of Project Summit resulted in total operating expenditures ("Restructuring Charges") of approximately 
$450,000 that primarily consisted of: (1) employee severance costs; (2) internal costs associated with the development and 
implementation of Project Summit initiatives; (3) professional fees, primarily related to third party consultants who assisted with the 
design and execution of various initiatives as well as project management activities and (4) system implementation and data 
conversion costs.

Restructuring Charges included in the accompanying Consolidated Statement of Operations for the years ended December 31, 
2021, 2020 and 2019, and from the inception of Project Summit through December 31, 2021, are as follows:

acquisition agreement also provides us the option to purchase, and the shareholders the option to sell, the remaining 
approximately 20% interest in ITRenew as follows: (i) approximately 16% on or after the second anniversary of the ITRenew 
Transaction and (ii) approximately 4% on or after the third anniversary of the ITRenew Transaction (collectively, the ”Remaining 
Interest"), each at a purchase price to be determined based upon the achievement of certain performance metrics, but for no less 
than $200,000 in total.

SCHEDULE III—SCHEDULE OF REAL ESTATE AND 
ACCUMULATED DEPRECIATION

DECEMBER 31, 2021
(Dollars in thousands)

Schedule III - Schedule of Real Estate and Accumulated Depreciation (“Schedule III”) reflects the cost and associated accumulated 
depreciation for the real estate facilities that are owned. The gross cost included in Schedule III includes the cost for land, land 
improvements, buildings, building improvements and racking. Schedule III does not reflect the 1,184 leased facilities in our real 
estate portfolio. In addition, Schedule III does not include any value for financing leases for property that is classified as land, 
buildings and building improvements in our consolidated financial statements.

The following table presents a reconciliation of the gross amount of real estate assets, as presented in Schedule III below, to the 
sum of the historical book value of land, buildings and building improvements, racking and construction in progress as disclosed in 
Note 2.h. to Notes to Consolidated Financial Statements as of December 31, 2021:
