2017 Annual Financial Report and
Stockholder  Letter

Dear Fellow Stockholders,

2017 was a successful year characterized by significant progress  against  our strategic plan and solid momentum in the business.
We achieved strong internal storage revenue growth—or  before  acquisitions—in all markets. Furthermore, we continued to
expand into high-growth emerging markets and leveraged  our brand  through extension into Adjacent Businesses. Additionally,  we
announced  three acquisitions in the data center space that further  expand our market position in this high-growth segment. As a
result of this shift in our business mix, we expect to accelerate growth in internal revenue and Adjusted EBITDA between now
and the end of 2020, compared with our expectations just  one year ago.

Our performance for 2017 was consistent with our expectations,  reflecting the strength of our global position and the discipline of
our management team, and was underscored by robust storage  rental  growth and enhanced margins. Our 2017 financial results
also benefitted from favorable currency translation after three years of foreign exchange headwinds. We remain steadily on track
to deliver on  our 2020 financial and strategic goals through continued growth in our core business and further expansion into
emerging markets and adjacent businesses whilst continuing to de-lever.  And our plan to achieve these targets is anchored by a
disciplined  investment strategy oriented toward faster-growing, value-creating businesses.

Strong 2017 Financial Performance Consistent  with Expectations

Total revenue grew by 10% year-over-year, reflecting the continued durability of both our physical records and data management
businesses,  as well as acquisition benefits and favorable foreign exchange fluctuations. Internal storage rental growth of 3.9% for
the year—our strongest performance since 2009—was primarily  driven by revenue management efforts in developed markets,
despite flat records management volumes. Globally, we  continued  to  see volume growth, driven primarily by emerging markets. In
2017, we added more than 47 million cubic feet of new  records from new and existing customers globally, or net volume growth
of  7 million cubic feet after destructions and customer terminations.  Our unwavering focus on customer satisfaction resulted in
continued retention of 98% in records management, highlighting the durability of our customer relationships. Adjusted EBITDA
growth of 16%  for the year exceeded revenue growth, demonstrating continued margin improvement. Growth in Adjusted
EBITDA and margins was driven by synergies from the Recall Transaction as well as savings from our Transformation Initiative.
Adjusted Funds From Operations, or AFFO, for 2017 was  at the high end of our expectations as we continued to optimize our
capital expenditures. We believe AFFO is a more representative metric of the cash generation characteristics of our operating
business and provides a good measure for dividend coverage. Lastly, and most importantly, our strong cash generation drove
roughly 7% growth in our dividend per share and supported discretionary investments.

Our growth expectations for 2018 on a constant dollar  basis remain consistent with our long-term strategic plans and reflect the
durability of our storage rental business as well as our expanding Data Center platform. At the midpoint of our guidance ranges
and on a constant currency basis, we expect growth in Total Revenues  of 8%, Adjusted EBITDA of 14%, and AFFO of 9% in
2018. We  expect  to drive this performance through continued  internal storage rental revenue growth, which is expected to be
between  3% and 3.5%, reflecting ongoing revenue management efforts in developed markets and volume growth in emerging
markets. Lastly, we continue to expect our cash available for distributions and investments to cover our anticipated 2018
dividend, required capital expenditures and a portion of  our discretionary investments and acquisitions.

Continuing to Deliver on our Strategic  Plan

Our strategic  plan remains focused on extending our durable business model through: continued nurturing of our core developed
markets, expanding into faster-growing emerging markets,  and  scaling our storage-related Adjacent Businesses, such as data
centers as well as fine art and entertainment services. We continue to focus on shifting our revenue mix toward our higher
growth portfolio, which includes Emerging Markets and Adjacent Businesses. Following our transformative acquisition of IO Data
Centers, our Data Center platform is expected to drive Adjacent Businesses to approximately 10% of total revenues by 2020
compared to  our initial goal of 5%. We expect to grow our data center  business through expansion within our existing footprint,
greenfield  development in the largest U.S. markets such as Northern Virginia, and targeted acquisitions in the top 20 global data
center markets. In Emerging Markets, we have made great  strides  to  expand our presence—both organically and through
acquisitions in core records management businesses. Our  expectation remains that these high growth markets will represent 20%
of  revenues by  2020. Therefore, our  objective  by 2020 is to reach 30% of total revenues from our higher growth portfolio
compared to  20% currently. As this shift in mix progresses, we expect  to  see faster Adjusted EBITDA growth and further
improvement in Adjusted EBITDA margins.

Driving Growth and Profitability in Developed Markets

In our Developed Markets segments, which include North American Records and Information Management as well as North
American Data Management and our Western European segment, we  achieved internal storage revenue growth of 3.4% with
modestly positive internal volume growth on a trailing twelve month basis. Internal storage revenue growth in North America—
and increasingly in Western Europe—is driven more by revenue management rather than by organic volume growth. It is
important to  note that whilst our successful revenue management effort may marginally impact incoming volume from existing
customers, it has not significantly impacted new customer behavior, nor  has it caused an increase in customer terminations or
destructions.

Given our successful implementation in North America, we plan to add revenue management resources to Western Europe, Asia,
Latin America, Australia and Eastern Europe during 2018. Furthermore, we will continue to seek growth from existing customers
through revenue management programs and sales of services,  and  we will focus on volume growth from further penetration of
unvended customers such as those in the mid-market and U.S. Federal government segments.

Emerging Markets Offer High-growth Potential

Our goal remains to expand into faster-growing emerging markets, which now represent more than 18% of total revenue, almost
double  the  relative size from about four years ago. Our progress  was supported by emerging market acquisitions closed during
the year with a total purchase price of more than $87 million. Notable  among emerging market transactions in 2017 were:
acquisition  of the remaining portions of our 2016 acquisition of  Santa Fe businesses in South Korea, the Philippines and China;
our entry into the Middle East; acquisitions in Peru and  Cyprus; and a transaction in India that moved us into the market-leading
position. We continue to have a strong pipeline of attractive  acquisition opportunities in emerging markets supporting our
confidence in  reaching our goal of 20% of total revenue from  these markets by the end 2020. We are pleased with the progress
we’re making to deepen our presence in key growth markets that  continue to experience strong high-single-digit internal storage
revenue  growth.

Significant Progress and Realignment  in Adjacent Businesses

Given our acquisition of IO Data Centers, we have begun reporting on our data center business as a separate segment. We have
removed entertainment services from our North American Data  Management segment and combined it with our fine art storage
business, as  the nature of the storage assets and customer bases  for these two businesses are more similar. As a result, our
Corporate & Other Business segment, which includes Adjacent Businesses, now comprises fine art storage as well as
Entertainment  Services. In September 2017, we completed the acquisition of Bonded Services, a provider of storage and services
for media  content preservation, including fine art vaults and shipping; logistics and distribution; and related services for
high-value physical and digital assets such as film, audio and video.  Bonded managed more than 10 million of these assets for its
2,000 clients worldwide, with offices in the United States, Canada,  the United Kingdom, France, the Netherlands and Hong
Kong, providing digital services that help media and entertainment companies extend their content across digital platforms. This
acquisition  also scales our existing U.S. entertainment services business and broadens our geographic footprint.

Innovation to Fuel Future Growth

We continue to drive toward diversification of our revenue streams through innovation. At a high level, our innovation efforts are
focused on customer solutions and processes that can further  strengthen our differentiation and support growth in storage and
service, whilst addressing our customers’ requirements  for their own digital transformations. A couple of examples to highlight
are working in partnership with our customers and machine learning companies to seek deeper insight into the data we store on
their behalf,  trials in the consumer storage space, and  our recently launched Iron Cloud(cid:2). Iron Cloud is an enterprise-class data
management platform that delivers integrity, availability and protection of digital assets, enabling our customers to securely
manage video content, mitigate cyber threats, increase operational  efficiency and drive more value from digital information.

Focus on Data Centers—Transformative IO Data Centers Acquisition

In December of 2017, we announced our agreement to acquire the United States operations of IO Data Centers, a leading data
center colocation space and solutions provider based in Phoenix, Arizona. The purchase included the land and buildings
associated with four data centers in Phoenix and Scottsdale,  Arizona; Edison, New Jersey; and Columbus, Ohio, for $1.3 billion,
plus up to $35 million of potential future payments associated with the execution of future customer contracts. We completed the
acquisition  early in January 2018, funding it through the issuance of  equity and debt. Also in 2017, we acquired Fortrust Data
Center,  providing us with a top-quality Tier 3 facility serving the attractive Denver market, and announced our plan to acquire
two Credit Suisse data centers located in London and  Singapore, which we closed in March 2018. Our data center expansion is
closely aligned  with our strategic goals, extending our business model to a faster growing segment whilst increasing our existing
data center capacity to a potential of more than 250 MW.  It  also  builds  on customer relationships and leverages our strong brand
for safety,  security and trust. We expect our expanded footprint will increase attractiveness to enterprise data center customers.
Importantly, it protects our durable, growing, high-margin business by increasing our exposure to faster-growth businesses with
higher-margin  storage revenue that are also REIT-friendly and tax-efficient. And lastly, it helps drive sustainable growth in cash
flow and dividend per share whilst de-leveraging, with a  continued  focus  on maximizing shareholder value. The data center
market continues to be very attractive, fueled in a large  way by  the movement of enterprise customers to private and public cloud
computing environments. For Iron Mountain, the data  center business has proven to be a natural extension of our brand where
customers see us as their trusted guardian for all things information and data storage related.

In conclusion, 2017 was a very good year with solid execution on our strategic plan. We continued to drive improved internal
storage revenue growth across both developed and emerging markets.  The recent expansion of our Data Center business is
expected to  accelerate our organic EBITDA growth from 3.5% currently to more than 5% in 2020. We have done all this whilst
remaining committed to our financial framework and targets. From a yield perspective, we continue to be a standout in the
S&P 500 with a strong dividend, plus robust and sustainable  growth. As we continue to execute on our strategic plan to extend
the durability  of our business by capturing opportunities  in adjacent businesses and emerging markets, we are truly appreciative
of  the continued support of our customers, stockholders and Mountaineers around the globe.

Yours sincerely,

9OCT201511395301

Item 1. Business.   

Business Overview

We store records, primarily physical records and data backup media, provide colocation and wholesale data center space, 

and provide information management and data center solutions that help organizations around the world protect their 
information, lower storage rental 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 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, and increased litigation, regulatory compliance and disaster recovery requirements. We provide data center facilities to 
protect digital information and ensure the continued operation of our customers’ IT infrastructures, with secure and reliable 
colocation and wholesale options. Founded in an underground facility near Hudson, New York in 1951, Iron Mountain 
Incorporated, a Delaware corporation, has more than 225,000 customers in a variety of industries in 53 countries around the 
world as of December 31, 2017. 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, 2017, we employed more than 24,000 people.

Now in our 67th year, we have experienced tremendous growth, particularly since successfully completing the initial 
public offering of our common stock in February 1996, at which time we operated fewer than 85 facilities (6 million square 
feet) with limited storage and information management service offerings and annual revenues of approximately $104.0 million. 
We are now a global enterprise providing storage, data center space and a broad range of related records and information 
management and data center solutions, as well as entertainment, arts and media storage and services, to customers in markets 
around the world with over 1,400 facilities (87.5 million square feet) and total revenues of more than $3.8 billion for the year 
ended December 31, 2017. We are listed on the New York Stock Exchange (the "NYSE") and on the Australian Stock 
Exchange ("ASX"). We are a constituent of the Standard & Poor's 500 Index and the MSCI REIT index and, as of 
December 31, 2017, we were number 729 on the Fortune 1000.

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

financial model is based on the recurring nature of our storage rental revenues and resulting storage net operating income. 
Supported by consistent and predictable storage rental revenues, we generate durable, low-volatility growth.

Recall Acquisition

On May 2, 2016 (Sydney, Australia time), we completed the Recall Transaction. We purchased Recall, a multi-national 

records and information management company for approximately $2.2 billion, comprising of $331.8 million in cash and 
approximately 50.2 million shares of our common stock based on the closing price of our common stock as of April 29, 2016 
(the last day of trading on the NYSE prior to the closing of the Recall Transaction) of $36.53 per share.

The Durability of Our Business

A significant amount of activity generated in the information management industry is the result of legislative 
requirements. To varying degrees across the world, organizations are required by law to create certain records and to retain 
them for a specified period of time. These laws may also impose more stringent requirements on personal information regarded 
as being sensitive, such as financial and medical information. As a third party provider, we assist customers to improve data 
security and establish programs to ensure compliance with their regulatory obligations. Storage of information can be 
performed in-house by businesses or governments (unvended) or it can be outsourced, in whole or in part, to a third party 
provider (vended). We believe the in-house portion still represents a majority of the total global information management 
market, offering a substantial unvended opportunity even in developed geographic markets with lower rates of economic 
growth.

1

We believe that the creation of document-based information will be sustained, as "paperless" technologies have prompted 

the creation of hard copies and have also led to increased demand for electronic records storage and services, such as the 
storage and off-site rotation of computer backup media. In addition, we believe that the proliferation of digital information 
technologies and distributed data networks has created a growing need for efficient, cost-effective, high quality technology 
solutions for electronic data protection and the management of electronic documents. We expect that the volume of stored 
physical and electronic records will continue to increase on a global basis for a number of reasons, including: (1) regulatory 
requirements; (2) requirements to support current and possible future litigation and the resulting increases in volume and 
holding periods of records; (3) the continued growth in data as a result of enhanced data processing technologies; 
(4) inexpensive document producing technologies; (5) the high cost of reviewing records and deciding whether to retain or 
destroy them; (6) the failure of many entities to adopt or follow policies on records destruction; (7) the need to keep backup 
copies of certain records in off-site locations for business continuity purposes in the event of disaster; and (8) the opportunity 
for companies to monetize the value that may reside in stored data and information for new commercial purposes.

Business Strategy

Overview 

We have transitioned from a growth strategy driven primarily by organic growth and acquisitions of storage and 

information management services companies to a strategy that targets multiple sources of revenue growth. Our growth strategy 
is focused on: (1) increasing revenues in developed markets such as the United States, Canada, Australia and western Europe, 
primarily through improved sales and marketing efforts and attractive fold-in acquisitions; (2) establishing and enhancing 
leadership positions in high-growth emerging markets such as central and eastern Europe, Latin America, Africa and Asia, 
primarily through acquisitions; and (3) continuing to identify, incubate and scale adjacent business opportunities ("ABOs") to 
support our long-term growth objectives and drive solid returns on invested capital. In our developed markets, we expect 
continuous improvement initiatives will generate modest profit growth. In our existing emerging markets, we expect profits 
will grow as the local businesses scale, and we will look to reinvest a portion of that improvement to support the growth of 
these businesses. We have made significant progress through acquisitions and organic growth in scaling our data center 
business, which began as an ABO but now has achieved such a size that we no longer consider it an ABO. In addition, we 
continue to pursue other businesses adjacent to our core such as entertainment, fine art and consumer storage and services.

Storage rental is the key driver of our economics and allows us to expand our relationships with our customers through 

value-added services that flow from storage rental. Consistent with our overall strategy, we are focused on increasing incoming 
volumes on a global basis. There are multiple sources of new volumes available to us, and these sources inform our growth 
investment strategy. Our investments in sales and marketing support sales to new customers that do not currently outsource 
some or all of their storage and information management needs, as well as increased volumes from existing customers. We also 
expect to invest in acquisitions of customer relationships and storage and information management services businesses. In our 
developed markets, we expect that these acquisitions will primarily be fold-in acquisitions designed to optimize the utilization 
of existing assets, expand our presence and better serve customers. We also expect to use acquisitions to expand our presence in 
attractive, higher growth emerging markets. Finally, we continue to pursue new rental streams through data centers and ABOs.

We offer our customers an integrated value proposition by providing them with secure storage and comprehensive service 

offerings, including records and information management services, data management services and archival cloud storage for 
digital records. We have the expertise and experience to address complex storage and information management challenges, 
such as rising storage rental costs, increased litigation, regulatory compliance and disaster recovery requirements. Our objective 
is to continue to capitalize on our brand, our expertise in the storage and information management industry and our global 
network to enhance our customers' experience, thereby maintaining our strong customer retention rates and attracting new 
customers. Our overall growth strategy will focus on growing our business organically, making strategic customer acquisitions, 
pursuing acquisitions of storage and information management businesses, developing adjacent businesses (organically and 
through acquisitions) and optimizing our real estate portfolio. We continue to expand our portfolio of products and services, 
based on our customers' evolving requirements. Adding new products and services allows us to strengthen our existing 
customer relationships and attract new customers in previously untapped markets.

Growth from Existing and New Customers

Our existing customers' storage of physical records contributes to the growth of storage rental and certain records and 

information management services revenues because, on average, our existing customers generate additional records at a faster 
rate than old records are destroyed or permanently removed. We seek to maintain high levels of customer retention by 
providing premium customer service and a variety of services tied to records management and information governance. While 
the rate of growth of new physical records from existing customers in our more mature markets has been declining, we seek to 
maintain revenue growth from existing customers through sales of services, further penetration of unvended customers in the 
mid-market and United States federal government vertical market segments and revenue management programs.

Our sales coverage model is designed to identify and capitalize on incremental revenue opportunities by strategically 

allocating our sales resources to our customer base and selling additional storage, records and information management 
services and products in new and existing markets. Our sales force is dedicated to three primary objectives: (1) establishing 
new customer account relationships; (2) generating additional revenue by expanding existing customer relationships globally; 
and (3) expanding new and existing customer relationships by effectively selling a wide array of related service and product 
offerings. In order to accomplish these objectives, our sales forces draw on our United States and international marketing 
organizations and senior management. We have developed tailored marketing strategies to target customers in the healthcare, 
financial, insurance, legal, life sciences, energy, business services and United States federal government vertical market 
segments.

Growth through Acquisitions in our Core Business 

The storage and information management services industry is highly fragmented with thousands of competitors in North 
America and around the world. Between 1995 and 2004 there was significant consolidation in the industry. Acquisitions were a 
fast and efficient way to achieve scale, expand geographically and broaden service offerings. After 2004, our acquisition 
activity was reduced as we focused on integrating those transactions and diversifying the business. Beginning again in 2012, 
we saw opportunities for attractive acquisitions in emerging markets and consolidation opportunities in more developed 
markets, and resumed acquisition activity. We believe this ongoing acquisition activity is due to opportunities for large 
providers to achieve economies of scale and meet customer demands for sophisticated, technology-based solutions. Attractive 
acquisition opportunities, in North America and internationally, continue to exist, and we expect to continue to pursue 
acquisitions of businesses we believe present good returns and good opportunities to create value for our stockholders. Lastly, 
we have a successful record of acquiring and integrating these businesses.

We have acquired, and we continue to seek to acquire, storage and information management services businesses in 
developed markets including the United States, Canada, Australia and western Europe. Given the relatively small size of most 
attractive acquisition targets in these markets, future acquisitions are expected to be less significant to our overall revenue 
growth in these markets than in the past.

On May 2, 2016, we completed the acquisition of Recall for approximately $2,166.9 million. In connection with the 
Recall Transaction, we acquired the entirety of Recall's global operations, including all facilities, vehicles, employees and 
customer assets (excluding certain operations of Recall that we were required to divest subsequent to the closing of the Recall 
Transaction in accordance with agreements with regulatory authorities in the United States, Canada and the United Kingdom). 
We believe the acquisition of Recall accelerates our growth strategy. After the Recall Transaction, with our broader footprint, 
stronger infrastructure, increased exposure to high growth emerging markets and small to mid-size enterprise customers, and 
increased economies of scale, we believe we are well suited to address unmet document storage and information management 
needs around the globe.

We expect to continue to make acquisitions and investments in storage and information management services businesses 
in targeted emerging markets outside the United States, Canada, Australia and western Europe. We have acquired and invested 
in, and seek to acquire and invest in, storage and information management services companies in certain countries, and, more 
specifically, certain markets within such countries, where we believe there is potential for significant growth. We expect that 
future acquisitions and investments in our emerging markets will focus primarily on expanding priority markets in central and 
eastern Europe, Latin America and Asia.

The experience, depth and strength of local management are particularly important to our emerging markets acquisition 
strategy. Since beginning our international expansion program in January 1999, we have, directly and through joint ventures, 
expanded our operations such that, as of December 31, 2017, we operated in 53 countries. These transactions have taken, and 
may continue to take, the form of acquisitions of an entire business or controlling or minority investments generally with a 
long-term goal of full ownership. We believe a joint venture strategy, rather than an outright acquisition, may, in certain 
markets, better position us to expand the existing business. Our local partners benefit from our expertise in the storage and 
information management services industry, our multinational customer relationships, our access to capital and our technology, 
while we benefit from our local partners' knowledge of the market, relationships with their local customers and their presence 
in the community. In addition to the criteria we use to evaluate developed market acquisition candidates, when looking at an 
emerging market acquisition, we also evaluate risks uniquely associated with an international investment, including those risks 
described below. Our long-term goal is generally to acquire full ownership of each business in which we make a joint venture 
investment. We own more than 98% of our international operations, measured as a percentage of consolidated revenues.

Our emerging market investments are subject to risks and uncertainties relating to the indigenous political, social, 

regulatory, tax and economic structures of other countries, as well as fluctuations in currency valuation, exchange controls, 
expropriation and governmental policies limiting returns to foreign investors.

Growth of our Data Center Business

With the rapid acceleration of growth in digital data and use of cloud storage, highly regulated companies and public 
sector organizations are selecting third-party providers such as us to host their data center infrastructure. The primary benefits 
of outsourcing include the ability to make more efficient use of real estate and the benefits of professional management. In 
addition, data center outsourcing provides improved connectivity, increased operational efficiency, predictable cost structure, 
consumption-based pricing, and flexibility with access to seamless expansion.

We have been providing customers, primarily in highly regulated industries, with colocation and wholesale data center 

space and solutions for more than 15 years. We seek to differentiate ourselves from the competition due to our experience with 
highly regulated industries, chief compliance officers and customers who are particularly focused on data security and 
mitigating risk. Our commitment to and reputation for highly secure operations was a major driver behind our agreement 
announced in October 2017 to acquire two data centers from Credit Suisse in London and Singapore for an aggregate cash 
purchase price of approximately $100.0 million (see Note 6 to Notes to Financial Consolidated Statements included in this 
Annual Report). We intend to continue to expand our data center capabilities to service customers in multiple geographies, 
focused on the top 20 global data center markets based on space absorption. We expect to grow through organic expansion 
within our existing footprint, greenfield development in the largest United States markets such as our campus in Manassas, 
Virginia, and targeted acquisitions of properties with customer profiles that closely mirror our own, such as the acquisition of 
Fortrust, a Denver based data center provider, in September 2017 for a total aggregate purchase price of approximately $137.5 
million.

On December 11, 2017, we entered into a purchase agreement to acquire the United States operations of IO Data Centers, 
LLC (“IODC”), a leading data center colocation space and solutions provider based in Phoenix, Arizona, including the land and 
buildings associated with four state-of-the-art data centers in Phoenix and Scottsdale, Arizona, Edison, New Jersey, and 
Columbus, Ohio, for an aggregate cash purchase price of $1,315.0 million (the “Initial IODC Consideration”), plus up to $60.0 
million of additional proceeds (including (i) $25.0 million of contingent consideration (the “IODC Contingent Consideration”) 
and (ii) $35.0 million of contingent payments associated with the execution of future customer contracts), subject to certain 
adjustments as set forth in the purchase agreement (the “IODC Transaction”).  

On January 10, 2018, we completed the IODC Transaction. At the closing of the IODC Transaction, we paid 

approximately $1,340.0 million of total consideration, consisting of the Initial IODC Consideration and the full amount of the 
IODC Contingent Consideration. We financed the consideration for the IODC Transaction with the proceeds from the Equity 
Offering, the Over-Allotment Option and the issuance of the 5¼% Notes (each as defined in Notes 4 and 13 to Notes to 
Consolidated Financial Statements included in this Annual Report). The existing data center space in the four owned facilities 
totals 728,000 square feet, providing 62 megawatts ("MW") of capacity with expansion potential of an additional 77 MW in 
Arizona and New Jersey. This acquisition marks a transformative step toward addressing our customers’ data center needs by 
dramatically expanding our platform and capabilities. It positions us as a leading data center company with an expanded 
platform and ability to offer colocation space in certain leading markets. With this transaction and following the closing of the 
aforementioned Credit Suisse acquisition expected in early 2018, our data center portfolio will total more than 90 MW of 
existing capacity, with an additional 26 MW of capacity currently under construction and planned and future expansion 
potential of another 135 MW.

Growth through ABOs

ABOs, which currently primarily consist of our entertainment and fine art storage and services businesses, include 

business lines that we consider investing in to grow and diversify our business. We are seeking businesses with long-term, 
recurring revenues, preferably with storage rental attributes, which are consistent with, and will enhance, our REIT structure. A 
dedicated team is focused on identifying and evaluating these opportunities.  If we are able to demonstrate success and meet 
return thresholds, we may acquire businesses to further accelerate our growth in the relevant ABO. Importantly, the ABO 
process includes financial hurdles and decision gates to help us evaluate whether we scale or discontinue investments in these 
opportunities, consistent with our disciplined approach to capital allocation.

We have been in the entertainment storage and services business for a number of years, providing storage and solutions to 

entertainment and media companies in North America. Entertainment and media companies around the globe require 
specialized storage facilities and solutions for protecting and preserving their intellectual property ("IP") while maintaining 
accessibility with changing technology and uses. Essential to those needs are secure, climate-controlled vaults for physical 
media preservation (art, film and audio/video tape) as well as a digital environment capable of protecting that IP from hackers 
and data loss. Having a single provider - the physical and digital storage, as well as the capabilities to transform content to new 
media formats for monetization and longer-term preservation - provides chain-of-custody for these companies. We are well 
positioned to meet these customer needs.

On December 1, 2015 we completed the acquisition of Crozier Fine Arts ("Crozier"), a storage, logistics and 

transportation business for high-value paintings, photographs and other types of art belonging to individual collectors, galleries 
and art museums. Crozier is a leader in art storage and an industry advocate for worldwide standards. This acquisition builds 
upon our expertise in storing, protecting and managing high-value items and supports our strategy to leverage our real estate 
network to accelerate growth. In addition, since our acquisition of Crozier, we have expanded our fine arts storage business by 
acquiring the assets of two art storage and handling companies in the United States: Fairfield Fine Arts in Ridgefield, 
Connecticut and Cirkers Brooklyn in Brooklyn, New York.

We believe the fine art storage industry is a growing, but fragmented, industry marked by increasing international interest 

and changes in purchasing habits by collectors and museums. We believe the increase in contemporary art as a focus for 
collectors has caused a spike in storage needs, while the increase in auction “turnover” - the rate at which catalogs, collections 
and individual pieces are made available for auction - has heightened the need for transportation, shipping, and related services. 
Taken together, we believe these factors will result in continued growth of the fine art storage industry. 

On September 29, 2017, we completed the acquisition of Bonded Services of America, Inc. and Bonded Services 
Acquisition, Ltd. (together, "Bonded"), providers of media asset storage and management services for global entertainment and 
media companies, for approximately 62.0 million British pounds sterling (or approximately $83.0 million, based upon the 
exchange rate between the British pound sterling and the United States dollar on the closing date of the acquisition of Bonded), 
subject to customary adjustments.  Bonded provides storage and services for media content preservation, management and 
distribution, including fine art vaults and shipping; logistics and distribution; supply chain; and related services for high value 
physical and digital assets, including works of art, film, audio and video. Bonded managed more than 10 million of these assets 
for its 2,000 clients worldwide, with offices in the United States, Canada, the United Kingdom, France, the Netherlands and 
Hong Kong, capable of providing in-house digital services that help media and entertainment companies extend their content 
across digital platforms. This acquisition scales our existing entertainment storage and services business and broadens our 
geographic footprint.

Business Characteristics

We generate our revenues by renting storage space to a large and diverse customer base around the globe and providing 

an expanding menu of related and ancillary products and services. Providing outsourced storage is the mainstay of our 
customer relationships and serves as the foundation for the majority of our revenue growth. Services are a complementary part 
of a comprehensive records management program and consist primarily of the handling and transportation of stored records and 
information, shredding, the scanning, imaging and document conversion services of active and inactive records ("Information 
Governance and Digital Solutions"), data restoration projects, the storage, assembly, reporting and delivery of customer 
marketing literature, or fulfillment services ("Fulfillment Services"), consulting services, product sales (including specially 
designed storage containers and related supplies), technology escrow services, and recurring project revenues.

Secure Storage

Our storage operations, our largest source of revenue, consist of providing non-dedicated storage rental space to our 
customers. Non-dedicated space allows our customers to increase or decrease the volume of their physical storage over the life 
of the contract based on their storage needs, while also reducing their risk of loss in the event of natural disaster. Given this 
non-dedicated space dynamic, the large portfolio of customer contracts, and the fact that no customer accounted for more than 
1% of our consolidated revenues for the year ended December 31, 2017, we assess the performance of our storage rental 
business predominantly by analyzing trends in segment-level storage rental volume and storage rental revenue. Additionally, 
our storage operations include technology escrow services.

Records storage consists primarily of the archival storage of records for long periods of time according to applicable 

laws, regulations and industry best practices. The secure off-site storage of data backup media is a key component of a 
company's disaster recovery and business continuity programs. Storage rental charges are generally billed monthly on a per 
storage unit basis and include the provision of space, racking systems, computerized inventory and activity tracking, and 
physical security.

Physical Records Storage

Physical records may be broadly divided into two categories: active and inactive. Active records relate to ongoing and 

recently completed activities or contain information that is frequently referenced. Active records are usually stored and 
managed on-site by their owners to ensure ready availability. Inactive physical records are the principal focus of the storage and 
information management services industry and consist of those records that are not needed for immediate access but which 
must be retained for legal, regulatory and compliance reasons or for occasional reference in support of ongoing business 
operations. Inactive physical records are typically stored for long periods of time with limited activity in cartons packed by the 
customer. For some customers, we store individual files on an open shelf basis as these files are typically more active.

Physical records may also include critical or irreplaceable data such as film, fine art and other highly proprietary 

information, such as energy data. We continue to identify additional areas of physical storage that fit with our core 
competencies in security and transportation, seeking to provide enterprise storage to businesses in much the same manner that 
self-storage companies serve consumers. Physical records may require special facilities, either because of the data they contain 
or the media on which they are recorded. Accordingly, our charges for providing enhanced security and special climate-
controlled environments for these vital records are higher than for typical storage rental.

Electronic Records Storage

Electronic records management focuses on the storage of, and related services for, computer media that is either a backup 

copy of recently processed data or archival in nature and data backup and storage on our proprietary cloud. Computer tapes, 
cartridges and disk packs are transported off-site by our courier operations on a scheduled basis to secure, climate-controlled 
facilities, where they are available to customers 24 hours a day, 365 days a year, to facilitate data recovery in the event of a 
disaster. Frequently, backup tapes are rotated from our facilities back to our customers' data centers. We also manage tape 
library relocations and support disaster recovery testing and execution. Electronic storage consists of (i) storage and rotation of 
backup computer media as part of corporate disaster recovery plans; (ii) server and computer backup services; (iii) digital 
content repository systems to house, distribute, and archive key media assets; and (iv) storage, safeguarding and electronic or 
physical delivery of physical media of all types, primarily for entertainment and media industry clients. 

6

We believe the issues encountered by customers trying to manage their electronic records are similar to the ones they face 

in their physical records management programs and consist primarily of: (1) storage capacity and the preservation of data; 
(2) access to and control over the data in a secure environment; and (3) the need to retain electronic records due to regulatory 
requirements or for litigation support. Customer needs for data backup and recovery and archiving are distinctively different 
from the storage of physical records. Backup data exists because of the need of many businesses to be able to recover their data 
in the event of a system failure, casualty loss or other disaster. It is customary (and a best practice) for data processing groups to 
rotate backup tapes to offsite locations on a regular basis and to store multiple copies of such information at multiple sites. We 
expect continued increase in demand for computer media backup, as it provides off-line storage or storage that is not connected 
to the Internet and provides superior protection against data breaches and hacks. In addition to the physical storage and rotation 
of backup data that we provide, we offer online backup services through partnerships as an alternative way for businesses to 
store and access data. Online backup is an Internet-based service that automatically backs up computer data from servers or 
directly from desktop and laptop computers over the Internet and stores it in secure data centers.

In 2017, we launched Iron Mountain Iron Cloud. Iron Cloud is our enterprise-class cloud storage platform and services 

offering for comprehensive data protection, preservation, restoration and recovery. With Iron Cloud, organizations can deploy a 
hybrid data management strategy with the benefits of a cloud service, but with predictable cost models and integrated security 
that scales for enterprises of all sizes, as well as data accessibility through a self-service portal providing transparency and 
control for efficient storage operations. Iron Cloud provides on demand block and object storage, accessible through secure 
connectivity from the enterprise to Iron Mountain's network of secure data centers. Iron Cloud addresses the critical stages of 
enterprise data management with advanced orchestration and automation for managing data sprawl, while securing data in 
motion and at rest and catering to the unique security and operational needs of medical imaging, surveillance video and other 
specialty media. 

Cloud services are increasingly becoming an integral part of many organizations' IT and data environments. As companies 

continue to transform their businesses with technology, they are facing data growth and complex challenges of determining 
what data to retain, where to store it and how to manage data access. Seeking to address these challenges, organizations are 
systematically replacing the practice of retaining data on premises and opting for hybrid models that require reliable and secure 
cloud storage. As a cloud storage platform for end-to-end data management, Iron Cloud addresses where to store data and the 
challenges of protecting, preserving and accessing data to address business requirements. Our approach to data management 
also enables organizations to manage risk by complying with industry standards and implementing advanced schemes to protect 
against cyberattacks.

Service Offerings

Complementary to any records management program is the handling and transportation and the eventual destruction of 

records upon the expiration of retention periods. These activities are accomplished through our complementary service and 
courier operations. Service charges are generally assessed for each activity on a per unit basis. Courier operations consist 
primarily of the pickup and delivery of records upon customer request. Charges for courier services are based on urgency of 
delivery, volume and location and are billed monthly. As of December 31, 2017, our courier fleet consisted of approximately 
4,700 owned or leased vehicles. Our other services include information destruction services (primarily secure shredding) 
("Destruction"), Information Governance and Digital Solutions, Compliant Records Management and Consulting Services, and 
other ancillary services.

Information Destruction Services

Our Destruction services consist primarily of (1) secure shredding operations which typically include the scheduled pick-
up of loose office records that customers accumulate in specially designed secure containers we provide and (2) secure IT asset 
destruction. In addition, secure shredding is a natural extension of our hard copy records management services by completing 
the lifecycle of a record and involves the shredding of sensitive documents for customers that, in many cases, store their 
records with us. Complementary to our shredding operations is the sale of the resultant waste paper to third-party recyclers. 
Through a combination of plant-based shredding operations and mobile shredding units consisting of custom built trucks, we 
are able to offer secure shredding services to our customers throughout the United States, Canada, Australia, and Latin 
America.

Information Governance and Digital Solutions

The focus of our Information Governance and Digital Solutions business is to develop, implement and support 
comprehensive storage and information management solutions for the complete lifecycle of our customers' information. We 
seek to develop solutions that solve our customers' document management challenges by integrating the management of 
physical records, document conversion and digital storage. Our Information Governance and Digital Solutions offerings 
complement our service offerings and enhance our existing customer relationships. We differentiate our offerings from our 
competitors by providing solutions that complement and expand our existing portfolio of products and services. The trend 
towards increased usage of Electronic Document Management ("EDM") systems represents another opportunity for us to 
manage active records. Our Information Governance and Digital Solutions offerings provide the bridge between customers' 
physical documents and their EDM solutions.

Industry Tailored Services

We offer records and information management services that have been tailored for specific industries, such as healthcare, 
or to address the needs of customers with more specific requirements based on the critical nature of their records. For example, 
medical records tend to be more active in nature and are typically stored on specialized open shelving systems that provide 
easier access to individual files. In addition to storing medical records, we provide health care information services, which 
include the handling, filing, processing and retrieval of medical records used by hospitals, private practitioners and other 
medical institutions, as well as recurring project work and ancillary services. Our industry tailored services include Health 
Information Management Solutions, Entertainment Services and Energy Data Services.

Other Ancillary Services

Other services we provide include recurring project work, such as the on-site removal of aged patient files and related 

computerized file indexing. Ancillary healthcare information services include release of information (medical record copying 
and delivery), temporary staffing, contract coding, facilities management and imaging. We offer a variety of additional services 
which customers may request or contract for on an individual basis. These services include conducting records inventories, 
packing records into cartons or other containers, and creating computerized indices of files and individual documents. We also 
provide services for the management of active records programs. We can provide these services, which generally include 
document and file processing and storage, both offsite at our own facilities and by supplying our own personnel to perform 
management functions on-site at a customer's premises. Other services that we provide include Fulfillment Services and 
Compliant Records Management and Consulting Services.

Our Business Fundamentals

Our business fundamentals are based on the recurring nature of our various revenue streams. We generate attractive 
returns from our differentiated storage rental business model because our occupancy costs, whether in a leased or owned 
building, are incurred per square foot while our storage revenue is generally earned per cubic foot. The historical predictability 
of our revenues and the resulting profitability allows us to operate with a high degree of financial leverage. Our business 
fundamentals consist of:

•  Recurring Revenues.  We derive a majority of our consolidated revenues from fixed periodic, usually monthly, storage 
rental fees charged to customers based on the volume of their records stored. Once a customer places physical records 
in storage with us, and until those records are destroyed or permanently removed (for which we typically receive a 
service fee), we receive recurring payments for storage rental without incurring additional labor or marketing expenses 
or significant capital costs. Similarly, contracts for the storage of electronic backup media involve primarily fixed 
monthly rental payments. This storage rental revenue base also provides the foundation for our service revenues and 
increases in profitability.

A customer is allocated a certain amount of storage space in our storage facilities but is not allocated a dedicated 
building or space in a particular building. In practice, we can, and sometimes will, for a variety of reasons, move 
records from one facility and into another facility. In order to track net move-in and move-out activity of customer 
materials, as well as to assess the optimization of our real estate portfolio, we regularly assess the utilization of our 
overall real estate portfolio. On a per building basis, we compare the amount of racking that is being used to store 
customer materials to the capacity of the entire building assuming it was fully racked ("Total Building Utilization"). 
Additionally, we compare the amount of racking that is being used to store customer materials to the capacity of the 
racking that has been installed ("Total Racking Utilization").  

We occasionally offer inducements to our customers in order to generate new business opportunities. Such 
inducements most commonly come in the form of providing free intake costs to transport a customer's records to one 
of our facilities, including labor and transportation costs ("Move Costs"), or payments that are made to a customer's 
current records management vendor in order to terminate the customer's existing contract with that vendor, or direct 
payments to a customer ("Permanent Withdrawal Fees"). We capitalize Move Costs and Permanent Withdrawal Fees 
(collectively, "Customer Inducements") as customer acquisition costs.

•  Historically Non-Cyclical Storage Rental Business.  Historically, we have not experienced significant reductions in 

our storage rental business as a result of economic downturns. We believe the durability of our storage rental business 
is driven by a number of factors, including the trend toward increased records retention, albeit at a lower rate of 
growth of incoming volume from our existing customers, as well as customer satisfaction with our services and 
contractual net price increases. On a global basis, the absolute number of new document storage cartons from our 
existing customers has been consistent in the past five years, and we anticipate this level will be sustained, although 
the rate of growth is slightly declining, given the continued growth in the total records volume. Total net volume 
growth, including acquisitions, was approximately 2%, 26% and 2% on a global basis for 2015, 2016 and 2017, 
respectively. The total net volume growth in 2016 was primarily driven by the impact of the Recall Transaction.

•  Diversified and Stable Customer Base.  As of December 31, 2017, we had more than 225,000 customers in a variety of 
industries in 53 countries around the world. We currently provide storage and information management services to 
commercial, legal, financial, healthcare, insurance, life sciences, energy, businesses services, entertainment and 
government organizations, including approximately 95% of the Fortune 1000. No single customer accounted for more 
than 1% of our consolidated revenues in any of the years ended December 31, 2015, 2016 and 2017. For each of the 
three years 2015 through 2017, the average annual volume reduction due to customers terminating their relationship 
with us was approximately 2%.

10

•  Capital Allocation.  All the characteristics of our business noted above support the durability of our cash flows, which 
in turn support our dividends and a portion of our investments. Absent a large acquisition or significant investments in 
real estate, we typically generate cash flows to support our dividends, maintain our operations and infrastructure and 
invest in core growth opportunities. We plan on funding acquisitions, data center expansion, ABO investments and real 
estate investments primarily through incremental borrowings, proceeds from real estate sales and/or proceeds from the 
issuance of debt or equity securities (including our At The Market (ATM) Equity Program (as defined below), 
dependent on market conditions. We made two changes to our capital expenditure categories in 2017. We now 
separately identify two additional capital expenditure categories, Innovation and Growth Investment Capital Spend 
(previously included within Non-Real Estate Investment) and Data Center Capital Spend (previously primarily 
included in Real Estate Investment and Non-Real Estate Investment). We have reclassified the categorization of our 
prior year capital expenditures to conform with our current presentation. Below are descriptions of the major types of 
investments and other capital expenditures that we have made in recent years or that we are likely to consider in 2018:

Real Estate:

• 

• 

Investment: Real estate assets that support core business growth primarily related to investments in land, 
buildings, building improvements, leasehold improvements and racking structures that expand our revenue 
capacity in existing or new geographies, replace a long-term operational obligation or create operational 
efficiencies, or Real Estate Investment. 

Maintenance: Real estate assets necessary to maintain ongoing business operations primarily related to the 
repair or replacement of real estate assets such as buildings, building improvements, leasehold 
improvements and racking structures, or Real Estate Maintenance.

Non-Real Estate:

• 

• 

Investment: Non-real estate assets that either (i) support the growth of our business, and/or increase our 
profitability, such as customer-inventory technology systems, and technology service storage and processing 
capacity, or (ii) are directly related to the development of core products or services in support of our 
integrated value proposition and enhance our leadership position in the industry, including items such as 
increased feature functionality, security upgrades or system enhancements, or Non-Real Estate Investment.

Competition

We are a global leader in the physical storage and information management services industry with operations in 53 

countries as of December 31, 2017. We compete with our current and potential customers' internal storage and information 
management services capabilities. We compete with numerous storage and information management services providers in every 
geographic area where we operate. The physical storage and information management services industry is highly competitive 
and includes thousands of competitors in North America and around the world. 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, and we believe we generally compete 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 available power, security considerations, location, connectivity and rental rates, and we believe we 
generally compete effectively in each of these areas.

Alternative Technologies

We derive most of our revenues from rental fees for the storage of physical records and computer backup tapes and from 

storage related services. Alternative storage technologies exist, many of which require significantly less space than physical 
documents and tapes, and as alternative technologies are adopted, storage related services may decline as the physical records 
or tapes we store become less active and more archived. While storage of physical documents continues to grow, we continue 
to provide, primarily through partnerships, additional services such as online backup, designed to address our customers' need 
for efficient, cost-effective, high-quality solutions for electronic records and storage and information management.

Employees

As of December 31, 2017, we employed more than 8,400 employees in the United States and more than 15,600 
employees outside of the United States. At December 31, 2017, approximately 700 employees were represented by unions in 
North America (in California, Illinois, Georgia, New Jersey and Pennsylvania and three provinces in Canada) and 
approximately 3,600 employees were represented by unions in Latin America (in Argentina, Brazil and Chile).

12

 
 
 
 
 
 
 
All union and non-union employees are generally eligible to participate in our benefit programs, which include medical, 
dental, life, short and long-term disability, retirement/401(k) and accidental death and dismemberment plans. Certain unionized 
employees in California receive these types of benefits through their 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 
specified objectives for the unit in which they work. All union employees are currently under renewed labor agreements or 
operating under an extension agreement.

Insurance and Contractual Limitations on Liability

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.

Our customer contracts typically contain provisions limiting our liability for damages regarding the loss or destruction of, 

or damage to, records or information stored with us. Our liability for physical storage is often limited to a nominal fixed 
amount per item or unit of storage, such as per cubic foot, and our liability for data center, Information Governance and Digital 
Solutions, Destruction and other services unrelated to records stored with us is often limited to a percentage of annual revenue 
under the contract; however, some of our contracts with large volume accounts and some of the contracts assumed in our 
acquisitions contain no such limits or higher 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 addition to provisions 
limiting our liability, our customer contracts generally include a schedule setting forth the majority of the customer-specific 
terms, including storage rental and service pricing and service delivery terms. Our customers may dispute the interpretation of 
various provisions in their contracts. 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 a larger percentage of our growth is driven by acquisitions and customer 
contracts assumed in acquisitions make up a commensurately larger percentage of our customer contracts, our exposure to 
contracts with higher or no limitations of liability and disputes with customers over the interpretation of their contracts 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 in order to cover losses to us in connection with customer contract disputes.

Environmental Matters

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 in-depth environmental review of all of our properties, including those acquired in   
acquisitions we have completed. 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.

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.

Operational Risks

Our customers may shift from paper and tape storage to alternative technologies that require less physical space.

We derive most of our revenues from rental fees for the storage of physical records and computer backup tapes and from 

storage related services. Alternative storage technologies exist, many of which require significantly less space than physical 
records and tapes, and as alternative technologies are adopted, storage related services may decline as the paper documents or 
tapes we store become less active and more archival. 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 tape-based technologies, whether now existing or developed in the future, could adversely 
affect our businesses.

As stored records and tapes become less active our service revenue growth and profitability may decline.

Our records management and data protection service revenue growth is being negatively impacted by declining activity 

rates as stored records and tapes are becoming less active. The amount of information available to customers through the 
Internet or their own information systems has been steadily increasing in recent years, and we believe this trend continues to 
accelerate. As a result, while we continue to experience growth in storage rental, our customers are less likely than they have 
been in the past to retrieve records and rotate tapes, thereby reducing their service activity levels. At the same time many of our 
costs related to records and tape related services remain 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.

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

Some customers have taken actions designed to reduce costs associated with the retention of documents, including 
reducing the volume of documents they store and adopting more aggressive destruction practices. If we are unable to increase 
pricing over time, or if rates of destruction of documents stored with us increase substantially, particularly in our developed and 
slower growing markets, our financial condition and results of operations would be adversely affected.

Governmental and customer focus on data security could increase our costs of operations. We may not be able to fully offset 
these costs through increases in our rates. Incidents in which we fail to protect our customers' information against security 
breaches could result in monetary damages against us and could otherwise damage our reputation, harm our businesses and 
adversely impact our results of operations. In addition, if we fail to protect our own information, including information about 
our employees, we could experience significant costs and expenses as well as damage to our reputation.

In reaction to publicized incidents in which electronically stored information has been lost, illegally accessed or stolen, 

almost all states in the United States have adopted breach of data security statutes or regulations that require notification to 
consumers if the security of their personal information is breached, and, over the past few years, many states expanded the 
scope of their data breach notifications laws and shortened notification timelines. Some states in the United States have adopted 
regulations requiring every company that maintains or stores personal information to adopt a comprehensive written 
information security program. In addition, certain United States federal laws and regulations affecting financial institutions, 
health care providers and plans and others impose requirements regarding the privacy and security of information maintained 
by those institutions as well as notification to persons whose personal information is accessed by an unauthorized third party. 
Some of these laws and regulations provide for civil fines in certain circumstances and require the adoption and maintenance of 
privacy and information security programs; our failure to comply with any such programs may adversely affect our business. 
Continued governmental focus on data security may lead to additional legislative action in the United States. For example, the 
United States Congress has considered, and will likely consider again, legislation that would expand the federal data breach 
notification requirement beyond the financial and medical fields.

15

Also, an increasing number of countries have introduced and/or increased enforcement of comprehensive data protection 

and privacy laws, or are expected to do so. In Europe, Regulation (EU) 2016/679 (commonly referred to as GDPR) on the 
protection of natural persons with regard to the processing of personal data and on the free movement of such data will come 
into effect in May 2018 and will supersede Directive 95/46/EC, which has governed the processing of personal data since 1995. 
The new regulation will enhance the security and privacy obligations of entities, such as us, that process data of residents of 
members of the European Economic Area and substantially increase penalties for violations.

The continued emphasis on information security and compliance as well as increasing concerns about government 
surveillance may lead customers to request that we take additional measures to enhance security, store electronic data locally, 
and assume higher liability under our contracts. We have experienced incidents in which customers' backup tapes or other 
records have been lost, and we have been informed by customers that some of the incidents involved the loss of personal 
information, resulting in monetary costs to those customers for which we have provided reimbursement. As a result of 
legislative initiatives and client demands, we may have to modify our operations with the goal of further improving data 
security. Any such modifications may result in increased expenses and operating complexity, and we may be unable to increase 
the rates we charge for our services sufficiently to offset any increased expenses.

In addition to increases in the costs of operations or potential liability that may result from a heightened focus on data 
security or losses of information, our reputation may be damaged by any compromise of security, accidental loss or theft of our 
own records, or information that we maintain with respect to our employees, as well as customer data in our possession. We 
believe that establishing and maintaining a good reputation is critical to attracting and retaining customers. If our reputation is 
damaged, we may become less competitive, which could negatively impact our businesses, financial condition or results of 
operations.

Attacks on our internal IT systems could damage our reputation, harm our businesses and adversely impact our results of 
operations.

Our reputation for providing secure information storage to customers is critical to the success of our business. We have 

previously faced attempts by unauthorized users to gain access to our IT systems and expect to continue to face such attempts. 
Although we seek to prevent, detect and investigate these security incidents and have taken steps to prevent such security 
breaches, our IT and network infrastructure may be vulnerable to attacks by hackers or breaches due to employee error or other 
disruptions. Moreover, our ability to integrate businesses we acquire may challenge our ability to prevent such security 
breaches. We have, and expect to continue to, outsource certain accounting, payroll IT, human resource, facility management 
and back office support services to third parties, which may subject our IT and other sensitive information to additional risk. A 
successful breach of the security of our IT systems could lead to theft or misuse of our customers' proprietary or confidential 
information and result in third party claims against us and reputational harm. If our reputation is damaged, we may become less 
competitive, which could negatively impact our businesses, financial condition or results of operations.

Changing fire and safety standards may result in significant expense in certain jurisdictions.

As of December 31, 2017, we operated 1,316 records management, off-site data protection, data center and fine art 
storage facilities worldwide, including 627 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 all of our 
facilities were constructed, in all material respects, in compliance with laws and regulations in effect at the time of their 
construction or outfitting. In some instances local authorities having jurisdiction 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 Recall (and other businesses we have acquired or may acquire) with our 
business is the process of making certain investments in the acquired Recall 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.  

16

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 provisions limiting our liability regarding the loss or destruction of, or damage 

to, records, information, or other items stored with us. Our liability for physical storage is often limited to a nominal fixed 
amount per item or unit of storage (such as per cubic foot) and our liability for Information Governance and Digital Solutions, 
data center, Destruction and other services unrelated to records, information and other items stored with us is often limited to a 
percentage of annual revenue under the contract; however, some of our contracts with large customers and some of the 
contracts assumed in our acquisitions contain no such limits or contain higher 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 addition to provisions limiting our liability, our customer contracts generally include a schedule setting forth the 
majority of the customer-specific terms, including storage rental and service pricing and service delivery terms. Our customers 
may dispute the interpretation of various provisions in their contracts. 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 a large percentage of our growth is driven by 
acquisitions and customer contracts assumed in acquisitions make up a commensurately larger percentage of our customer 
contracts, and as we expand our operations in storage of fine arts and other valuable items and respond to customer demands 
for higher limitation of liability as a result of regulatory changes, our exposure to contracts with higher or no limitations of 
liability and disputes with customers over the interpretation of their contracts 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 in order to cover losses to us in connection with customer contract disputes.

International operations may pose unique risks.

As of December 31, 2017, we provided storage and information management services in 52 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 to continue to acquire or invest in storage and information management services 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 regulations and United States regulations that apply to us in foreign countries where 
we operate; in particular, we are subject to United States and foreign anticorruption 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;
the volatility of certain foreign economies in which we operate;
political uncertainties and changes in the global political climate which may impose restrictions on global operations;
unforeseen liabilities, particularly within acquired businesses;
costs and difficulties associated with managing international operations of varying sizes and scale;
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;
cultural differences and differences in business practices and operating standards; and
foreign currency fluctuations.

In particular, our net income, debt balances or leverage can be significantly affected by fluctuations in currencies.

17

We have operations in numerous foreign countries and, as a result, are subject to foreign exchange translation risk, which 
could have an adverse effect on our financial results.

We conduct business operations in numerous foreign countries through our foreign subsidiaries or affiliates, which 

primarily transact in their respective local currencies. Those local currencies are translated into United States dollars at the 
applicable exchange rates for inclusion in our consolidated financial statements. The results of operations of, and certain of our 
debt balances (including intercompany debt balances) associated with, our international businesses are exposed to foreign 
exchange rate fluctuations, and as we have expanded our international operations, our exposure to exchange rate fluctuations 
has increased. Upon translation, operating results may differ materially from expectations, and significant shifts in foreign 
currencies can impact our short-term results, as well as our long-term forecasts and targets. In addition, because we intend to 
distribute 100% of our REIT taxable income to our stockholders, and any exchange rate fluctuations may negatively impact our 
REIT taxable income, our distribution amounts (including the classification of our distributions as nonqualified ordinary 
dividends, qualified ordinary dividends or return of capital, as described more fully in "Item 5. Market For Registrant's 
Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities" included in this Annual Report) may 
fluctuate as a result of exchange rate fluctuations.

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.

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 
barred from future United States Government contracting. We may also face private derivative securities claims as a result 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;
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, 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 in-depth environmental review of all of our properties, including those acquired in 
acquisitions we have completed. 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.

18

Unexpected events could disrupt our operations and adversely affect our reputation and results of operations.

Unexpected events, including fires or explosions at our facilities, natural disasters such as hurricanes and earthquakes, 
war or terrorist activities, unplanned power outages, supply disruptions and failure of equipment or systems, could adversely 
affect our reputation and results of operations. Our customers rely on us to securely store and timely retrieve their critical 
information, and these 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. 
During the past several years we have seen an increase in severe weather events and some of our key facilities worldwide are 
subject to this inherent risk.

Damage to our reputation could adversely affect our business, financial condition and results of operations.

Our reputation for providing highly 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. For example, events such as fires, natural disasters, attacks on our IT 
systems or security breaches involving us could negatively impact our reputation, particularly if such incidents result in adverse 
publicity, governmental investigations or litigation. Damage to our reputation could make us less competitive, which could 
negatively impact our business, financial condition and results of operations.

Following the consummation of the IODC Transaction, our data center business comprises a greater portion of our overall 
operations, increasing the likelihood that significant costs or disruptions at our data centers could adversely affect our 
business, financial condition and results of operations.

During 2017 and the first quarter of 2018, we made several acquisitions in the data center space and we expect to 

continue to grow our data center business, both organically and through acquisitions. Our 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 center business. 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 as a result of numerous factors, including: 

human error;
equipment failure;
physical, electronic and cyber security breaches;
fire, hurricane, flood, earthquake and other natural disasters;
extreme temperatures;
power loss or telecommunications failure;

• 
• 
• 
• 
• 
• 
•  war, terrorism and any related conflicts or similar events worldwide; and
• 

sabotage and vandalism.

Our 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. 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 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.

Our data centers are subject to environmental laws and regulations. For example, our emergency generators 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 as well as our data management locations may include ozone-depleting 
substances that are subject to regulation. Changes in law or our operations could increase compliance costs or impose 
limitations on our operations. While environmental regulations do not normally impose material costs upon operations at our 
data centers, unexpected events, equipment malfunctions, human error and changes in law or regulations, among other factors, 
could result in unexpected costs due to violation of environmental laws, required permits or additional operation limitations or 
costs.

19

Furthermore, after giving effect to the IODC Transaction, the Credit Suisse transaction and our acquisition in September 
2017 of Mag Datacenters LLC, which operated Fortrust, a Denver-based data center provider, we will have paid an aggregate 
cash purchase price of over $1.5 billion for data center businesses in 2017 and the first quarter of 2018. We may be required to 
commit significant operational and financial resources in connection with the growth of our data center business. However, 
there can be no assurance we will have sufficient customer demand to support these data centers or that we will not be 
adversely affected by the risks noted above, which could make it difficult for us to realize expected returns on our investments, 
if any. 

Our shared service center initiative may not create the operational efficiencies that we expect, and may create risks relating to 
the processing of transactions and recording of financial information, which could have an adverse effect on our financial 
condition and results of operations.  

We have undertaken a shared service center initiative pursuant to which we are centralizing certain finance, human 
resources and IT functions. We have and will continue to align the design and operation of our financial control environment as 
part of our shared service center initiative. As part of this initiative, we are outsourcing, and will continue to outsource, certain 
IT accounting, payroll, IT, facility management, and human resource functions to third party service providers. The parties that 
we utilize for these services may not be able to handle the volume of activity or perform the quality of service necessary to 
support our operations. The failure of these parties to fulfill their obligations could disrupt our operations. In addition, the move 
to a shared service environment, including our reliance on third party providers, may create risks relating to the processing of 
transactions and recording of financial information. Particularly during the transition period, we could experience a lapse in the 
operation of internal controls due to turnover, lack of legacy knowledge, inappropriate training and use of third party providers, 
which could result in significant deficiencies or material weaknesses in our internal control over financial reporting and have an 
adverse effect on our financial condition and results of operations.

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 to recyclers. As a result, significant declines 
in the cost of paper may negatively impact our revenues and results of operations, and increases in other commodity prices, 
including steel, may negatively impact our results of operations. 

We may be subject to claims that our technology violates the IP rights of a third party.

Third parties may have legal rights (including ownership of patents, trade secrets, trademarks and copyrights) to ideas, 
materials, processes, names or original works that are the same or similar to those we use. Third parties have in the past, and 
may in the future, bring claims, or threaten to bring claims, against us that allege that their IP rights are being infringed or 
violated by our use of IP. Litigation or threatened litigation could be costly and distract our senior management from operating 
our business. Further, if we cannot establish our right or obtain the right to use the IP on reasonable terms, we may be required 
to develop alternative IP at our expense to mitigate potential harm.

We face competition for customers.

We compete with multiple storage and information management services providers in all geographic areas where we 
operate; our current or potential customers may choose to use those competitors instead of us. 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.

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, 2017, our total long-term debt was approximately 
$7.1 billion. 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, strategic opportunities, including 
acquisitions and expansions into adjacent businesses, and other general corporate requirements, including possible 
required repurchases 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.

In connection with the IODC Transaction, we incurred approximately $825.0 million of additional indebtedness. As a 
result of the indebtedness we incurred in connection with the IODC Transaction, we are subject to increased risks associated 
with debt financing, including an increased risk that our cash flow could be insufficient to meet required payments on our debt.  

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

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

incur additional indebtedness;
pay dividends or make other restricted payments;

• 
• 
•  make asset dispositions;
• 
•  make acquisitions and other investments.

create or permit liens; and

These restrictions may adversely affect our ability to pursue our acquisition and other growth strategies.

We may not have the ability to raise the funds necessary to finance the repurchase of outstanding senior or senior subordinated 
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 or senior subordinated 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. 

21

Iron Mountain is a holding company, and, therefore, our ability to make payments on our various debt obligations depends in 
large part on the operations of our subsidiaries.

Iron Mountain is a holding company; substantially all of our assets consist of the stock of our subsidiaries, and 

substantially all of our operations are conducted by our direct and indirect 100% owned subsidiaries. As a result, our ability to 
make payments on our various debt obligations will be dependent upon the receipt of sufficient funds from our subsidiaries. 
However, our various debt obligations are guaranteed, on a joint and several and full and unconditional basis, by our direct and 
indirect 100% owned United States subsidiaries, that represent the substantial majority of our United States operations.

Acquisition and Expansion Risks

Elements of our strategic growth plan involve inherent risks.

As part of our strategic growth plan, we expect to invest in new business strategies, products, services, technologies and 
geographies, including data centers and ABOs, and we may selectively divest certain businesses. These initiatives may involve 
significant risks and uncertainties, including distraction of management from current operations, insufficient revenues to offset 
expenses and liabilities associated with new investments, inadequate return of capital on these investments and the inability to 
attract, develop and retain skilled employees to lead and support new initiatives. For example, in recent years, we have 
expanded our entry into the data center and fine art storage businesses. Our data center expansion in particular requires 
significant capital commitments and includes other costs associated with the development of real estate to support this business. 
Many of these 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 also face competition from other companies in our efforts to 
grow our adjacent businesses, some of which possess substantial financial and other resources. As a result, we may be unable to 
acquire, or may pay a significant purchase price for, adjacent businesses that support our strategic growth plan.  

Failure to manage our growth may impact our results of operations.

If we succeed in expanding our existing businesses, or in moving into new areas of business, that expansion may place 

increased demands on our management, operating systems, internal controls and financial and physical resources. If not 
managed effectively, these increased demands may adversely affect the services we provide to customers. In addition, our 
personnel, systems, procedures and controls may be inadequate to support future operations, particularly with respect to 
operations in countries outside of the United States or in new lines of business. Consequently, in order to manage growth 
effectively, we may be required to increase expenditures to increase our physical resources, expand, train and manage our 
employee base, improve management, financial and information systems and controls, or make other capital expenditures. Our 
results of operations and financial condition could be harmed if we encounter difficulties in effectively managing the 
budgeting, forecasting and other process control issues presented by future growth.

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, 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, such as IODC and Recall, will depend, in large part, on our 
ability to realize the anticipated benefits, including cost savings 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 structures between the 
two businesses; 
consolidating corporate and administrative infrastructures; 
coordinating geographically dispersed organizations;
potential unknown liabilities and unforeseen expenses or delays associated with an acquisition; and 
our ability to deliver on our strategy going forward.

22

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 operations of 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.

We may be unable to continue our international expansion.

An important part of our growth strategy involves expanding operations in international markets, including in markets 
where we currently do not operate, and we expect to continue this expansion. Europe, Latin America and Australia have been 
our primary areas of focus for international expansion, and we have expanded into Asia, Africa and the Middle East to a lesser 
extent. We have entered into joint ventures or have acquired all or a majority of the equity in storage and information 
management services businesses operating in these areas and may acquire other storage and information management services 
businesses in the future, including in new countries or markets where we currently do not operate. A changing global political 
climate may impose restrictions on our ability to expand internationally.  

This growth strategy involves risks. We may be unable to pursue this strategy in the future at the desired pace or at all. 

For example, we may be unable to:

• 
• 
• 
• 
• 

• 

identify suitable companies to acquire or invest in;
complete acquisitions on satisfactory terms;
successfully expand our infrastructure and sales force to support growth;
achieve satisfactory returns on acquired companies, particularly in countries where we do not currently operate;
incur additional debt necessary to acquire suitable companies if we are unable to pay the purchase price out of 
working capital, common stock or other equity securities; or
enter into successful business arrangements for technical assistance or management expertise outside of the United 
States.

We also compete with other storage and information management services providers as well as other entities for 
companies to acquire. Some of our competitors may possess substantial financial and other resources. If any such competitor 
were to devote additional resources to pursue such acquisition candidates or focus its strategy on our international markets, the 
purchase price for potential acquisitions or investments could rise, competition in international markets could increase and our 
results of operations could be adversely affected.

Our net proceeds from the Divestments may be lower than expected and we may be subject to liabilities as a result of provisions 
in the sale agreements governing the Divestments.

The terms of the sale agreements governing the Divestments (as defined in Note 6 to Notes to Consolidated Financial 

Statements included in this Annual Report) in the United States, Canada and Australia provide for post-closing adjustments to 
the purchase prices. As a result, the purchase prices for the Divestments may be adjusted in accordance with the terms of the 
sale agreements. As such, the expected net proceeds of the Divestments are uncertain and the actual net proceeds we receive 
from the Divestments may be less than the net proceeds expected by us. Furthermore, in the sale agreements governing the 
Divestments, we have made certain representations and warranties and are bound by certain covenants following the closings. 
Any breach of such terms may subject us to liabilities in accordance with the terms of the sale agreements.

23

We have guaranteed certain obligations of Recall to Brambles relating to Brambles' prior demerger transaction.

On December 18, 2013, Brambles Limited, an Australian corporation ("Brambles"), implemented a demerger transaction 

by way of a distribution of shares of Recall to Brambles’ shareholders (the “Demerger”). Prior to and in connection with the 
Demerger, Brambles spun off certain of its United States and Canadian subsidiaries, directly or indirectly, to Recall. Such spin-
offs were intended to be tax-free or tax-deferred under United States and Canadian tax laws, respectively, and Brambles 
obtained rulings from the IRS (with respect to the United States spin-off) and the Canada Revenue Agency (with respect to the 
Canadian spin-off), as well as opinions of its tax advisors, to such effect. However, the tax-free status of the spin-off of such 
United States subsidiaries could be adversely affected under certain circumstances if a 50% or greater interest in such United 
States subsidiaries were acquired as part of a plan or series of related transactions that included such spin-off. Similarly, the tax-
deferred status of the spin-off of the Canadian subsidiaries could be adversely affected under certain circumstances if control of 
such subsidiaries were acquired as part of a series of transactions or events that included such spin-off.

In connection with the Demerger, Recall agreed to indemnify Brambles and certain of its affiliates for taxes to the extent 

that actions by Recall (e.g., an acquisition of Recall shares) resulted in the United States spin-off or the Canadian spin-off 
described above failing to qualify as tax-free or tax-deferred for United States or Canadian tax purposes, respectively. In 
addition, Recall agreed, among other things, that it would not, within two years of the 2013 spin-offs, enter into a proposed 
acquisition transaction, merger or consolidation (with respect to the United States spin-off) or take any action that could 
reasonably be expected to jeopardize, directly or indirectly, any of the conclusions reached in the Canadian tax ruling or 
opinion, without obtaining either a supplemental tax ruling from the relevant taxing authority, the consent of Brambles or an 
opinion of a tax advisor, acceptable to Brambles in its reasonable discretion, that such transaction should not result in the spin-
offs failing to be tax-free under United States federal income tax law or Canadian tax law, respectively. Recall has obtained 
such tax opinions, based on, among other things, representations and warranties made by Recall and us. Such opinions do not 
affect Recall’s obligation to indemnify Brambles for an adverse impact on the tax-free status of such prior spin-offs.

We have guaranteed the foregoing indemnification obligations of Recall. Consistent with the foregoing tax opinions, we 

believe that the Recall Transaction is not part of a plan or series of related transactions, or part of a series of transactions or 
events, that included the United States spin-off or the Canadian spin-off, respectively. However, if the IRS or the Canadian 
Revenue Agency were to prevail in asserting a contrary view, we would be liable for the resulting taxes, which could be 
material.

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 since our 2014 taxable year; 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 taxed 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 Internal 

Revenue Code of 1986, as amended (the "Code"), which provisions may change from time to time, 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.

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 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.

24

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, such as 
capital expenditures, payments of compensation for which Section 162(m) of the Code denies a deduction, interest expense 
deductions limited by Section 163(j) of the Code, the creation of reserves or required debt service or amortization payments.

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 REIT distribution requirements, to comply with asset 
ownership tests or to fund capital expenditures, future growth and expansion initiatives.

In order to meet the 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 
the then-prevailing market conditions are not favorable for these borrowings, sales or offerings. Any insufficiency of our cash 
flows to cover our REIT distribution requirements could adversely impact our ability to raise short- and long-term debt, to sell 
assets, or to offer equity securities in order to fund distributions required to maintain our qualification and taxation as a REIT. 
Furthermore, the REIT distribution requirements may increase the financing we need 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 rating, 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 Relating to Our Indebtedness."

Whether we issue equity, at what price and the amount and other terms of any such issuances will depend on many 
factors, including alternative sources of capital, our then-existing leverage, our need for additional capital, market conditions 
and other factors beyond our control. If we raise additional funds through the issuance of equity securities or debt convertible 
into equity securities, the percentage of stock ownership by our existing stockholders may be reduced. In addition, new equity 
securities or convertible debt securities could have rights, preferences and privileges senior to those of our current stockholders, 
which could substantially decrease the value of our securities owned by them. Depending upon the market price of our 
common stock at the time of any potential issuances of equity securities, we may have to sell a significant number of shares in 
order to raise the capital we deem necessary to execute our long-term strategy, and our stockholders may experience dilution in 
the value of their shares as a result.

In addition, if we fail to comply with specified asset ownership tests applicable to REITs as measured at the end of any 

calendar quarter, we 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. These actions may reduce our income and amounts available 
for distribution to our stockholders.

Complying with REIT requirements may limit our flexibility or cause us to forgo otherwise attractive opportunities.

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 taxable REIT subsidiaries ("TRSs"), and to that extent limit our opportunities and our 
flexibility to change our business strategy. 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.

25

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 25% of the 
value of the assets of a REIT may be represented by securities of one or more TRSs and other nonqualifying assets. In addition, 
no more than 20% of the value of the assets of a REIT may be represented by securities of one or more TRSs within the overall 
25% nonqualifying assets limitation. These limitations may affect our ability to make additional investments in non-REIT 
qualifying operations or assets or in international operations through TRSs.

Our ability to fully deduct our interest expense may be limited, or we may be required to adjust the tax depreciation of our real 
property in order to maintain the full deductibility of our interest expense.

December 2017 amendments to the Code, which are described more fully in the Tax Reform section of "Critical 

Accounting Policies" within Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations 
included in this Annual Report (the "Tax Reform Legislation"), limit interest deductions for businesses, whether in corporate or 
passthrough form, to the sum of the taxpayer’s business interest income for the tax year and 30% of the taxpayer’s adjusted 
taxable income for that tax year. This limitation does not apply to an “electing real property trade or business.” We have not yet 
determined whether we or any of our subsidiaries will elect out of the new interest expense limitation or whether any of our 
subsidiaries is eligible to elect out, although legislative history indicates that a real property trade or business includes a trade or 
business conducted by a corporation or a REIT. Depreciable real property (including specified improvements) held by electing 
real property trades or businesses must be depreciated for United States federal income tax purposes under the alternative 
depreciation system of the Code, which generally imposes a class life for depreciable real property of up to 40 years.

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 principally 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, and 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 TRSs are overseas, and a material change in 
foreign currency rates could also negatively impact our ability to remain qualified for taxation as a REIT.

The Tax Reform Legislation has imposed limitations on the ability of our TRSs to utilize specified income tax deductions, 
including limits on the use of net operating losses and limits on the deductibility of interest expense. Further, these amendments 
made substantial changes to the taxation of international income. Some of these changes did not contemplate what we believe 
were unintended consequences of such reforms on REITs with global operations, and we may be required to recognize income 
on account of the activities of our foreign TRSs that may not be treated as qualifying income for purposes of the REIT gross 
income tests that we are required to satisfy. 

26

Our cash distributions are not guaranteed and may fluctuate.

A REIT generally is required to distribute at least 90% of its REIT taxable income to its stockholders.

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 services. Consequently, our distribution levels may fluctuate.

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 on 
our income and assets, 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.

Our information management services businesses and several of our international operations are conducted through 
wholly owned TRSs because these 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, we and 
our subsidiaries continue to be subject to foreign income taxes in 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. Any of these taxes would decrease our earnings and our available cash.

We will also be subject to a federal corporate level income tax at the highest regular corporate income tax rate (currently 
21%, following the enactment of the Tax Reform Legislation) on gains 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 (i) an asset that we held 
as of the effective date of our REIT election, that is, January 1, 2014, or (ii) an asset that we hold in one of our qualified REIT 
subsidiaries ("QRSs") following the liquidation or other conversion of a former TRS). This 21% 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 (e.g., January 
1, 2014 in the case of REIT assets we held at the time of our REIT conversion), 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, depreciation recapture income 
that we expect to recognize as a result of certain accounting method changes that we have made will be fully subject to this 
21% 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.

27

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 after 2017 and before 2026, REIT dividends paid to noncorporate 
stockholders 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 other than the first year for which we elected to be taxed as a REIT. 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.

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, or the administrative interpretations of those laws, 
may be amended. Federal and state tax laws are constantly under review by persons involved in the legislative process, the IRS, 
the United States Department of the Treasury (the "Treasury") and state taxing authorities. Changes to the tax laws, regulations 
and administrative interpretations, 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. 

28

The Tax Reform Legislation has made substantial changes to the Code, particularly as it relates to the taxation of both 

corporate income and international income. Among those changes are a significant permanent reduction in the generally 
applicable corporate income tax rate and the modification of tax policies, credits and deductions for businesses and individuals. 
This legislation also imposes additional limitations on the deduction of net operating losses, which may in the future cause us to 
make distributions that will be taxable to our stockholders to the extent of our current or accumulated earnings and profits in 
order to comply with the REIT distribution requirements.  The effect of these and other changes made in this legislation is 
highly uncertain, both in terms of their direct effect on the taxation of an investment in our securities and their indirect effect on 
the value of properties owned by us.  Furthermore, many of the provisions of the new law will require guidance through the 
issuance of Treasury regulations in order to assess their effect.  There may be a substantial delay before such regulations are 
promulgated, increasing the uncertainty as to the ultimate effect of the statutory amendments on us or our stockholders.  It is 
also possible that there will be technical corrections legislation proposed with respect to the Tax Reform Legislation, the effect 
of which cannot be predicted and may be adverse to us or our stockholders. Our stockholders are encouraged to consult with 
their tax advisors about the potential effects that changes in law may have on them and their ownership of our securities.

Risks Related to our Common Stock 

Sales or issuances of shares of our common stock may adversely affect the market price of our common stock.

Future sales or issuances of common stock or other equity related securities may adversely affect the market price of our 
common stock, including any shares of our common stock issued to finance capital expenditures, finance acquisitions or repay 
debt. In October 2017, we established an "at-the-market" stock offering program (the "At The Market (ATM) Equity Program") 
with a syndicate of 10 banks (the “Agents”), pursuant to which we may sell, from time to time, up to an aggregate sales price of 
$500.0 million of our common stock through the Agents. As of December 31, 2017, we have sold 1,481,053 shares of our common 
stock for gross proceeds of approximately $60.0 million under the At The Market (ATM) Equity Program.

The ability of our board of directors to change our major policies without the consent of stockholders may not be in the interest 
of our stockholders.  

Our board of directors determines our major policies, including policies and guidelines relating to our investments, 
acquisitions, leverage, financing, growth, operations and distributions to our stockholders. Our board of directors may amend or 
revise these and other policies and guidelines from time to time without the vote or consent of our stockholders. Accordingly, 
our stockholders will have limited control over changes in our policies, and any such changes could adversely affect our 
financial condition, results of operations, the market price of our common stock and our ability to make distributions to our 
stockholders.

The leased facilities typically have initial lease terms of five to ten 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.

During the years ended December 31, 2015, 2016 and 2017, we declared distributions to our stockholders of   

$402.6 million, $502.9 million and $603.7 million, respectively. These distributions represent approximately $1.91 per share, 
$2.04 per share and $2.27 per share for the years ended December 31, 2015, 2016 and 2017, respectively, based on the 
weighted average number of common shares outstanding during each respective year. 

On February 14, 2018, we declared a dividend to our stockholders of record as of March 15, 2018 of $0.5875 per share, 

payable on April 2, 2018.

33

 
 
 
 
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" for tax years beginning 
after 2017) qualified ordinary dividends or return of capital. The IRS 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. For the years 
ended December 31, 2015, 2016 and 2017, the dividends we paid on our common shares were classified as follows:

Nonqualified ordinary dividends

100.0% 100.0% 100.0%

Dividends paid during the years ended December 31, 2015, 2016 and 2017 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, 2015, 2016 and 2017. 

The change in the percentage of our dividends that were characterized as a return of capital in 2015 and 2016 (11.6% and 
33.5%, respectively) compared to 2017 (0.0%) is primarily a result of the impact of the Deemed Repatriation Transition Tax (as 
defined in Note 7 to Notes to Consolidated Financial Statements included in this Annual Report) associated with the Tax 
Reform Legislation that impacted the characterization of our 2017 dividends for United States federal income tax purposes. See 
the Tax Reform section of "Critical Accounting Policies" within Item 7. Management's Discussion and Analysis of Financial 
Condition and Results of Operations included in this Annual Report for further disclosure regarding the impact of the Deemed 
Repatriation Transition Tax and the Tax Reform Legislation on our 2017 dividends.

At The Market (ATM) Equity Program

In October 2017, we entered into a distribution agreement (the “Distribution Agreement”) with a syndicate of 10 banks 

(the “Agents”) pursuant to which we may sell, from time to time, up to an aggregate sales price of $500.0 million of our 
common stock through the Agents (the “At The Market (ATM) Equity Program”). Sales of our common stock made pursuant to 
the Distribution Agreement may be made in negotiated transactions or transactions that are deemed to be “at the market” 
offerings as defined in Rule 415 under the Securities Act of 1933, as amended (the "Securities Act"), including sales made 
directly on the NYSE, or sales made to or through a market maker other than on an exchange, or as otherwise agreed between 
the applicable Agent and us. We intend to use the net proceeds from sales of our common stock pursuant to the At The Market 
(ATM) Equity Program for general corporate purposes, including financing the expansion of our data center business and 
adjacent businesses through acquisitions, and repaying amounts outstanding from time to time under the Revolving Credit 
Facility (as defined in Note 4 to Notes to Consolidated Financial Statements included in this Annual Report).

During the quarter ended December 31, 2017 under the At The Market (ATM) Equity Program, we sold an aggregate of 

1,481,053 shares of common stock for gross proceeds of approximately $60.0 million, generating net proceeds of $59.1 million 
after deducting commissions of $0.9 million. As of December 31, 2017, the remaining aggregate sale price of shares of our 
common stock available for distribution under the At The Market (ATM) Equity Program was approximately $440.0 million.

Equity Offering

On December 12, 2017, we entered into an underwriting agreement (the “Underwriting Agreement”) with a syndicate of 

16 banks (the “Underwriters”), related to the public offering by us of 14,500,000 shares (the “Firm Shares”) of our common 
stock (the “Equity Offering”). The offering price to the public for the Equity Offering was $37.00 per share, and we agreed to 
pay the Underwriters an underwriting commission of $1.38195 per share. The net proceeds to us from the Equity Offering, after 
deducting underwriters' commissions, was $516.5 million.

34

 
 
Pursuant to the Underwriting Agreement, we granted the Underwriters a 30-day option to purchase from us up to an 

additional 2,175,000 shares of common stock (the “Option Shares”) at the public offering price, less the underwriting 
commission and less an amount per share equal to any dividends or distributions declared by us and payable on the Firm Shares 
but not payable on the Option Shares (the “Over-Allotment Option”). On January 10, 2018, the Underwriters exercised the 
Over-Allotment Option in its entirety. The net proceeds to us from the exercise of the Over-Allotment Option, after deducting 
underwriters' commissions and the per share value of the dividend we declared on our common stock on October 24, 2017 (for 
which the record date was December 15, 2017) which was paid on January 2, 2018, was approximately $76.2 million. The net 
proceeds of the Equity Offering and the Over-Allotment Option, together with the net proceeds from the issuance of the 51/4% 
Notes (as defined in Note 4 to Notes to Consolidated Financial Statements included in this Annual Report), were used to 
finance the purchase price of the IODC Transaction, which closed on January 10, 2018, and to pay related fees and expenses. 
At December 31, 2017, the net proceeds of the Equity Offering, together with the net proceeds from the 51/4% Notes, were used 
to temporarily repay borrowings under our Revolving Credit Facility and invest in money market funds.

Unregistered Sales of Equity Securities and Use of Proceeds

We did not sell any unregistered equity securities during the three months ended December 31, 2017, nor did we 

repurchase any shares of our common stock during the three months ended December 31, 2017.

The following discussion should be read in conjunction with "Item 6. Selected Financial Data" and the Consolidated 

Financial Statements and Notes thereto and the other financial and operating information included elsewhere in this Annual 
Report.

This discussion contains "forward-looking statements" as that term is defined in the Private Securities Litigation Reform

Annual Report and "Item 1A. Risk Factors" beginning on page 15 of this Annual Report.

Overview

Acquisitions

a. Recall Acquisition

On May 2, 2016 (Sydney, Australia time), we completed the Recall Transaction. At the closing of the Recall Transaction, 
we paid approximately $331.8 million in cash and issued approximately 50.2 million shares of our common stock which, based 
on the closing price of our common stock as of April 29, 2016 (the last day of trading on the NYSE prior to the closing of the 
Recall Transaction) of $36.53 per share, resulted in a total purchase price to Recall shareholders of approximately $2,166.9 
million. The results of operations of Recall have been included in our consolidated results from May 2, 2016. See Note 6 to 
Notes to Consolidated Financial Statements included in this Annual Report for unaudited pro forma results of operations for us 
and Recall, as if the Recall Transaction was completed on January 1, 2015, for the years ended December 31, 2015 and 2016, 
respectively.

We currently estimate total acquisition and integration expenditures associated with the Recall Transaction to be 

approximately $380.0 million, the majority of which is expected to be incurred by the end of 2018. This amount consists of (i) 
operating expenditures associated with the Recall Transaction, including: (1) advisory and professional fees to complete the 
Recall Transaction; (2) costs associated with the Divestments (as defined in Note 6 to Notes to Consolidated Financial 
Statements included in this Annual Report) required in connection with receipt of regulatory approvals (including transitional 
services); and (3) costs to integrate Recall with our existing operations, including moving, severance, facility upgrade, REIT 
conversion and system upgrade costs, as well as certain costs associated with our shared service center initiative for our 
finance, human resources and information technology functions ("Recall Costs"), and (ii) capital expenditures to integrate 
Recall with our existing operations. From January 1, 2015 through December 31, 2017, we have incurred cumulative operating 
and capital expenditures associated with the Recall Transaction of $313.8 million, including $263.9 million of Recall Costs and 
$49.9 million of capital expenditures.

See Note 16 to Notes to Consolidated Financial Statements included in this Annual Report for more information on Recall 

Costs, including costs recorded by segment as well as recorded between cost of sales and selling, general and administrative 
expenses.

b. IODC Acquisition

On December 11, 2017, we entered into a purchase agreement to acquire IODC, a leading data center colocation space 
and solutions provider based in Phoenix, Arizona, including the land and buildings associated with four data centers in Phoenix 
and Scottsdale, Arizona; Edison, New Jersey; and Columbus, Ohio, for an aggregate cash purchase  of the Initial IODC 
Consideration, plus up to $60.0 million of additional proceeds (including the IODC Contingent Consideration) and (ii) $35.0 
million of contingent payments associated with the execution of future customer contracts), subject to certain adjustments as set 
forth in the purchase agreement for the IODC Transaction.

On January 10, 2018, we completed the IODC Transaction. At the closing of the IODC Transaction, we paid 

approximately $1,340.0 million of total consideration, including the Initial IODC Consideration and the IODC Contingent 
Consideration. We financed the IODC Transaction through the proceeds from the Equity Offering, the Over-Allotment Option 
and the issuance of the 5¼% Notes.

38

Divestitures

a. Divestments Associated with the Recall Transaction

As disclosed in Note 6 to Notes to Consolidated Financial Statements included in this Annual Report, we sought 

regulatory approval of the Recall Transaction and, as part of the regulatory approval process, we agreed to make the 
Divestments.

The Initial United States Divestments, the Seattle/Atlanta Divestments, the Recall Canadian Divestments and the UK 

Divestments (each as defined in Note 6 to Notes to Consolidated Financial Statements included in this Annual Report) 
(collectively, the "Recall Divestments") meet the criteria to be reported as discontinued operations as the Recall Divestments 
met the criteria to be reported as assets and liabilities held for sale at, or within a short period of time following, the closing of 
the Recall Transaction. Accordingly, the results of operations for the Recall Divestments are presented as a component of 
discontinued operations in our Consolidated Statements of Operations for the years ended December 31, 2016 and 2017 and the 
cash flows associated with the Recall Divestments are presented as a component of cash flows from discontinued operations in 
our Consolidated Statements of Cash Flows for the years ended December 31, 2016 and 2017.

The Australia Divestment Business and the Iron Mountain Canadian Divestments (each as defined in Note 6 to Notes to 

Consolidated Financial Statements included in this Annual Report) (collectively, the "Iron Mountain Divestments") do not meet 
the criteria to be reported as discontinued operations as our decision to divest the Iron Mountain Divestments 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 the Iron Mountain Divestments are presented as a component of income (loss) from continuing operations in 
our Consolidated Statements of Operations for the years ended December 31, 2015 and 2016 and the cash flows associated 
with the Iron Mountain Divestments are presented as a component of cash flows from continuing operations in our 
Consolidated Statements of Cash Flows for the years ended December 31, 2015 and 2016.

The Australia Divestment Business represents approximately $65.0 million and $44.0 million of total revenues and 
approximately $5.8 million and $1.1 million of total income from continuing operations for the years ended December 31, 2015 
and 2016, respectively. The Iron Mountain Canadian Divestments represent approximately $2.7 million of total revenues and 
approximately $1.5 million of total income from continuing operations for each of the years ended December 31, 2015 and 
2016, respectively. The Australia Divestment Business was previously included in our Other International Business segment 
and the Iron Mountain Canadian Divestments were previously included in our North American Records and Information 
Management Business segment.

See Note 14 to Notes to Consolidated Financial Statements included in this Annual Report for additional information 

regarding the presentation of the Divestments in our Consolidated Statements of Operations and Consolidated Statements of 
Cash Flows for the years ended December 31, 2015, 2016 and 2017.  

b. Iron Mountain - Russia and Ukraine Divestment

On May 30, 2017, Iron Mountain EES Holdings Ltd. ("IM EES"), a consolidated subsidiary of IMI, sold its records and 

information management operations in Russia and Ukraine to OSG Records Management (Europe) Limited (“OSG”) in a stock 
transaction (the “Russia and Ukraine Divestment”). As consideration for the Russia and Ukraine Divestment, IM EES received 
a 25% equity interest in OSG (the "OSG Investment").

We have concluded that the Russia and Ukraine Divestment does not meet the criteria to be reported as discontinued 
operations in our consolidated financial statements, as our decision to divest these businesses 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 
these businesses are presented as a component of income (loss) from continuing operations in our Consolidated Statements of 
Operations for the years ended December 31, 2015, 2016 and 2017, respectively, and the cash flows associated with these 
businesses are presented as a component of cash flows from continuing operations in our Consolidated Statements of Cash 
Flows for the years ended December 31, 2015, 2016 and 2017, respectively. Our businesses in Russia and Ukraine represent 
approximately $16.3 million, $17.5 million and $8.6 million of total revenues for the years ended December 31, 2015, 2016 
and 2017, respectively. Our businesses in Russia and Ukraine represent approximately $(16.2) million, $0.3 million and $0.9 
million of total (loss) income from continuing operations for the years ended December 31, 2015, 2016 and 2017, respectively.

39

As a result of the Russia and Ukraine Divestment, we recorded a gain on sale of $38.9 million to other expense (income), 
net, in the second quarter of 2017, representing the excess of the fair value of the consideration received over the carrying value 
of our businesses in Russia and Ukraine. As of the closing date of the Russia and Ukraine Divestment, the fair value of the 
OSG Investment was approximately $18.0 million. As of the closing date of the Russia and Ukraine Divestment, the carrying 
value of our businesses in Russia and Ukraine was a credit balance of $20.9 million, which consisted of (i) a credit balance of 
approximately $29.1 million of cumulative translation adjustment associated with our businesses in Russia and Ukraine that 
was reclassified from accumulated other comprehensive items, net, (ii) the carrying value of the net assets of our businesses in 
Russia and Ukraine, excluding goodwill, of $4.7 million and (iii) $3.5 million of goodwill associated with our Northern and 
Eastern Europe reporting unit (of which our businesses in Russia and Ukraine were a component of prior to the Russia and 
Ukraine Divestment), which was allocated, on a relative fair value basis, to our businesses in Russia and Ukraine.

Transformation Initiative

During the third quarter of 2015, we implemented a plan that calls for certain organizational realignments to reduce our 

overhead costs, particularly in our developed markets, in order to optimize our selling, general and administrative cost structure 
and to support investments to advance our growth strategy (the “Transformation Initiative”). As a result of the Transformation 
Initiative, we recorded charges (which are included within selling, general and administrative expenses) of $10.2 million, $6.0 
million and $0.5 million for the years ended December 31, 2015, 2016 and 2017, respectively, primarily related to employee 
severance and associated benefits.

Costs recorded by segment associated with the Transformation Initiative are as follows (in thousands):

General

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, technology escrow services that protect 
and manage source code, data backup and storage on our proprietary cloud and revenues associated with our data center 
operations. Service revenues include charges for related service activities, which include: (1) the handling of records, including 
the addition of new records, temporary removal of records from storage, refiling of removed records and the destruction of 
records; (2) courier operations, consisting primarily of the pickup and delivery of records upon customer request; (3) secure 
shredding of sensitive documents and the related sale of recycled paper, the price of which can fluctuate from period to period; 
(4) other services, including the scanning, imaging and document conversion services of active and inactive records, or 
Information Governance and Digital Solutions, which relate to physical and digital records, and project revenues; (5) customer 
termination and permanent removal fees; (6) data restoration projects; (7) special project work; (8) the storage, assembly, 
reporting and delivery of customer marketing literature, or fulfillment services; (9) consulting services; (10) cloud-related data 
protection, preservation, restoration and recovery; and (11) other technology services and product sales (including specially 
designed storage containers and related supplies). 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.

Cost of sales (excluding depreciation and amortization) consists primarily of 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, wages and benefits 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. Trends in facility occupancy costs 
are impacted by the total number of facilities we occupy, the mix of properties we own versus properties we occupy under 
operating leases, 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 segment revenue. In addition, the overhead 
structure of our expanding international operations has generally not achieved the same level of overhead leverage as our North 
American segments, which may result in an increase in selling, general and administrative expenses as a percentage of 
consolidated revenue, as our international operations become a more meaningful percentage of our consolidated results.

Our depreciation and amortization charges result primarily from the capital-intensive nature of our business. The principal 

components of depreciation relate 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. 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 entities 

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 2015 results at the 2016 average exchange 
rates and the 2016 results at the 2017 average exchange rates. Constant currency growth rates are a non-GAAP measure.

Adjusted EBITDA

Adjusted EBITDA is defined as income (loss) from continuing operations before interest expense, net, provision (benefit) 

for income taxes, depreciation and amortization, and also excludes certain items that we believe are not indicative of our core 
operating results, specifically: (1) loss (gain) on disposal/write-down of property, plant and equipment (excluding real estate), 
net; (2) intangible impairments; (3) other expense (income), net; (4) gain on sale of real estate, net of tax; (5) Recall Costs; and 
(6) REIT Costs (as defined below). Adjusted EBITDA Margin is calculated by dividing Adjusted EBITDA by total revenues. 
We use multiples of current or projected Adjusted EBITDA in conjunction with our discounted cash flow models to determine 
our estimated overall enterprise valuation and to evaluate acquisition targets. We believe Adjusted EBITDA and Adjusted 
EBITDA Margin provide our current and potential investors with relevant and useful information regarding our ability to 
generate cash flow to support business investment. These measures are an integral part of the internal reporting system we use 
to assess and evaluate the operating performance of our business.

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. Finally, Adjusted EBITDA 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 excluding: (1) loss (gain) 

on disposal/write-down of property, plant and equipment (excluding real estate), net; (2) gain on sale of real estate, net of tax; 
(3) intangible impairments; (4) other expense (income), net; (5) Recall Costs; (6) REIT Costs; and (7) the tax impact of 
reconciling items and discrete tax items. Adjusted EPS includes income (loss) attributable to noncontrolling interests. 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.

ended December 31, 2013, 2014, 2015, 2016 and 2017 is primarily due to (i) the reconciling items above, which 
impact our reported income (loss) from continuing operations before provision (benefit) for income taxes but 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, 2013, 2014, 2015, 
2016 and 2017 was 15.0%, 14.4%, 16.8%, 18.5% and 19.7%, respectively.

FFO (Nareit) and FFO (Normalized)

Funds from operations (“FFO”) is defined by the National Association of Real Estate Investment Trusts ("Nareit") and us 

as net income (loss) excluding depreciation on real estate assets and gain on sale of real estate, net of tax (“FFO (Nareit)”). 
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. Although Nareit has 
published a definition of FFO, modifications to FFO (Nareit) are common among REITs as companies seek to provide financial 
measures that most meaningfully reflect their particular business. Our definition of FFO (Normalized) excludes certain items 
included in FFO (Nareit) that we believe are not indicative of our core operating results, specifically: (1) loss (gain) on 
disposal/write-down of property, plant and equipment (excluding real estate), net; (2) intangible impairments; (3) other expense 
(income), net; (4) Recall Costs; (5) the tax impact of reconciling items and discrete tax items; (6) (income) loss from 
discontinued operations, net of tax; and (7) loss (gain) on sale of discontinued operations, net of tax.

Critical Accounting Policies

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. Our critical accounting policies include the following, which are listed 
in no particular order:

Revenue Recognition

We recognize revenue when the following criteria are met: persuasive evidence of an arrangement exists, services have 

been rendered, the sales price is fixed or determinable and collectability of the resulting receivable is reasonably assured. 
Storage rental and service revenues are recognized in the month the respective storage rental or service is provided, and 
customers are generally billed on a monthly basis on contractually agreed-upon terms. Amounts related to future storage rental 
or prepaid service contracts for customers where storage rental fees or services are billed in advance are accounted for as 
deferred revenue and recognized ratably over the period the applicable storage rental or service is provided or performed. 
Revenues from the sales of products, which are included as a component of service revenues, are recognized when products are 
shipped and title has passed to the customer. Revenues from the sales of products have historically not been significant.

Accounting for Acquisitions

Part of our growth strategy has included the acquisition by us of numerous 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. 

During the third quarter of 2017, we adopted Accounting Standards Update No. 2017-01, Business Combinations (Topic 

805): Clarifying the Definition of a Business ("ASU 2017-01"). ASU 2017-01 provides guidance for evaluating whether 
transactions should be accounted for as acquisitions of assets or businesses. The guidance provides a screen to determine when 
an integrated set of assets and activities does not qualify to be a business. The screen requires that when substantially all of the 
fair value of the gross assets acquired is concentrated in an identifiable asset or a group of similar identifiable assets, the 
acquisition should not be accounted for as the acquisition of a business, but rather the acquisition of an asset. If an acquisition 
is determined to be a business, goodwill is recognized as part of purchase accounting, whereas with the acquisition of an asset 
there is no goodwill recognized.

Each acquisition has been accounted for using the acquisition method of accounting as defined under the applicable 
accounting standards at the date of each acquisition. Accounting for these acquisitions 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 lease-based intangible 
assets), property, plant and equipment (primarily building and racking structures), operating leases, contingencies and income 
taxes (primarily deferred income taxes). We complete these assessments within one year of the date of acquisition, as we 
acquire additional information impacting our estimates as of the acquisition date. See Note 6 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. 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.

46

Of the net assets acquired in our acquisitions, the fair value of owned buildings, customer relationship and 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, 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 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 and leased-based intangible assets and acquired 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 and lease-based 
intangible assets, which requires a significant amount of judgment by management, including estimating expected lives of the 
relationships, expected future cash flows and discount rates.

Of the key assumptions that impact the estimated fair values of customer relationship intangible assets, the expected 
future cash flows and discount rate are among the most sensitive and are considered to be critical assumptions. To illustrate the 
sensitivity of changes in key assumptions used in determining the fair value of customer relationship intangible assets acquired 
in the Bonded Transaction (one of our more significant acquisitions in fiscal year 2017), a hypothetical increase of 10% in the 
expected annual future cash flows attributable to the Bonded Transaction, with all other assumptions unchanged, would have 
increased the calculated fair value of the acquired customer relationship intangible assets for the Bonded Transaction by 
$4.7 million (or 10.1%), with an offsetting decrease to goodwill. A hypothetical decrease of 100 basis points in the discount 
rate, with all other assumptions unchanged, would have increased the fair value of the acquired customer relationship intangible 
asset for the Bonded Transaction by $3.9 million (or 8.4%), with an offsetting decrease to goodwill.

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.

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 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.

47

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.

We have selected October 1 as our annual goodwill impairment review date. We performed our annual goodwill 

impairment review as of October 1, 2015 and 2016, concluding that no goodwill was impaired as of such dates. We performed 
our annual goodwill impairment review as of October 1, 2017 and, as a result of that review, we determined that the fair value 
of the Consumer Storage reporting unit (formerly referred to as the Adjacent Businesses - Consumer Storage reporting unit) 
was less than its carrying value and, therefore, we recorded a $3.0 million impairment charge on the goodwill associated with 
this reporting unit during the fourth quarter of 2017, which represents a write-off of all goodwill associated with this reporting 
unit. We concluded that goodwill associated with the remainder of our reporting units was not impaired as of October 1, 2017. 
Our reporting units at which level we performed our goodwill impairment analysis as of October 1, 2017 were as follows: (1) 
North American Records and Information Management; (2) North American Data Management; (3) Global Data Center; (4) 
Consumer Storage; (5) Fine Arts (formerly referred to as the Adjacent Businesses - Fine Arts reporting unit); (6) Western 
Europe; (7) Northern/Eastern Europe and Middle East, Africa and India (the "NEE and MEAI reporting unit"); (8) Latin 
America; (9) Australia and New Zealand; and (10) Asia (formerly referred to as the Southeast Asia reporting unit). See Note 
2.h. to Notes to Consolidated Financial Statements included in this Annual Report for a description of our reporting units.

Based on our goodwill impairment analysis as of October 1, 2017, our North American Records and Information 

Management, North American Data Management, Western Europe, NEE and MEAI and Asia reporting units had estimated fair 
values that exceeded their carrying values by greater than 20%. These reporting units represent approximately $3,538.2 million, 
or 86.9%, of our consolidated goodwill balance at December 31, 2017. Our Global Data Center reporting unit does not have 
goodwill. Our Consumer Storage reporting unit as of December 31, 2017 does not have goodwill, as the $3.0 million 
impairment charge disclosed above represented a full write-down of the goodwill associated with this reporting unit. Our Fine 
Arts, Latin America and Australia and New Zealand reporting units had estimated fair values that exceeded their carrying 
values by less than 20%. These reporting units (including the Entertainment Services reporting unit that was created in the 
fourth quarter of 2017, as described below) represent approximately $532.1 million, or 13.1%, of our consolidated goodwill 
balance at December 31, 2017. The following is a summary of the Fine Arts, Latin America and Australia and New Zealand 
reporting units, including goodwill balances (in thousands), percentage by which the fair value of these reporting units 
exceeded its carrying value, and certain key assumptions used by us in determining the fair value of the reporting unit as of

As described below, reporting unit valuations are generally determined using a combined approach based on the Income 

Approach and Market Multiple Approach (both as defined below). 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 those reporting units where the estimated fair values exceeded their 
carrying values by less than 20% as of October 1, 2017. The success of each of these businesses and the achievement of certain 
key assumptions developed by management and used in the discounted cash flow analyses are contingent upon various factors 
including, but not limited to, (i) achieving volume growth from existing customers, (ii) sales to new customers, (iii) increased 
market penetration, (iv) successful execution of pricing initiatives and (v) successful facility optimization and site consolidation 
plans. 

Our Fine Arts business operates in a growing, but fragmented, industry marked by increasing international interest and 

changes in purchasing habits by collectors and museums. We believe the increase in contemporary art as a focus for collectors 
will result in increasing storage needs, while the increase in auction “turnover” (the rate at which catalogs, collections and 
individual pieces are made available for auction) has heightened the need for transportation, shipping, and related services. 
Taken together, we believe these factors will result in continued growth of the fine art storage industry. The fine arts storage 
market continues to change and expand, and the assumptions used when determining the fair value of the Fine Arts reporting 
unit reflect this growth potential and the capital needs required to respond to the expansion opportunities. The Fine Arts 
reporting unit is primarily composed of a business we acquired in the fourth quarter of 2015; therefore, we would expect the 
fair value of this reporting unit to closely approximate carrying value.

Our Australia and New Zealand business operates in a more mature and established market. In 2016, we completed the 

sale of the Australia Divestment Business, which consisted of the majority of our legacy business in Australia as it existed prior 
to the Recall Transaction. Accordingly, our Australia and New Zealand business is primarily comprised of the Australia and 
New Zealand businesses we acquired as part of the Recall Transaction in 2016. Therefore, we would expect the fair value of 
this reporting unit to closely approximate its carrying value.

Our Latin America business operates in emerging markets. The success of this business is driven by our ability to improve 
contribution margin through operational efficiencies. We have completed many acquisitions in our Latin America business over 
the past several years and we continue to integrate these acquisitions into our existing operations. Our ability to drive our 
growth agenda while also maintaining cost discipline as we integrate our acquisitions will be important to the success of our 
Latin America business.

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 legal 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 Income Approach 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. 

As of December 31, 2017, no factors were identified that would alter our October 1, 2017 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. As described more fully in Note 2.h. to Notes to Consolidated Financial 
Statements included in this Annual Report, during the fourth quarter of 2017, as a result of changes in the management of our 
entertainment storage and services business, we reassessed the composition of our reportable operating segments as well as our 
reporting units. We determined that our entertainment storage and services businesses in the United States and Canada, which 
were previously included within our North American Data Management reporting unit, were being managed in conjunction 
with our entertainment storage and services businesses in France, Hong Kong, the Netherlands and the United Kingdom (the 
majority of which were acquired during the third quarter of 2017 as part of the Bonded Transaction). This newly formed 
reporting unit is referred to as the Entertainment Services reporting unit. The fair value of the Entertainment Services reporting 
unit closely approximated its carrying value as of December 31, 2017. 

Reporting unit valuations are generally determined using a combined approach based on the present value of future cash 

flows (the "Income Approach") and market multiples (the "Market Multiple Approach"). The Income Approach incorporates 
many assumptions including future growth rates and operating margins, discount rate factors, expected capital expenditures and 
income tax cash flows. Changes in economic and operating conditions impacting these assumptions 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.

49

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, 2017. With respect to the North American Records and Information Management, North American Data 
Management, Western Europe, NEE and MEAI and Asia reporting units as of October 1, 2017, we noted that, based on the 
estimated fair value of these reporting units determined as of October 1, 2017, (i) 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, 2017 by approximately 10.0% but would not, however, have 
resulted in the carrying value of any of these reporting units with goodwill exceeding their estimated fair value; and (ii) 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, 2017 by a range of approximately 6.1% to 7.8% but would not, 
however, have resulted in the carrying value of any of these reporting units with goodwill exceeding their estimated fair value. 
With respect to the Fine Arts, Latin America and Australia and New Zealand reporting units, we noted that, as of October 1, 
2017, the estimated fair value of these reporting units exceeds their carrying value by less than 20%. Accordingly, any 
significant negative change in either the expected annual future cash flows of these reporting units or the discount rate may 
result in the carrying value of these reporting units exceeding their estimated fair value. 

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 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 following the date on which that 
asset was first owned by a REIT that are attributable to "built-in" gains with respect to that asset on that date (e.g. with respect 
to the REIT conversion, the assets that we owned on January 1, 2014). This built-in gains tax has been imposed on our 
depreciation recapture recognized into income as a result of accounting method changes commenced in our pre-REIT period 
and in connection with the Recall Transaction. 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.

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.

We have federal net operating loss carryforwards, which expire from 2023 through 2036, of $66.3 million at December 

31, 2017 to reduce future federal taxable income, of which $1.7 million of federal tax benefit is expected to be realized. We can 
carry forward these net operating losses to the extent we do not utilize them in any given available year. We have state net 
operating loss carryforwards, which expire from 2018 through 2036, of which an insignificant state tax benefit is expected to be 
realized. We have assets for foreign net operating losses of $103.6 million, with various expiration dates (and in some cases no 
expiration date), subject to a valuation allowance of approximately 59%. 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.

50

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, 2016 
and 2017, we had approximately $59.5 million and $38.5 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.

During 2016, as a result of the closing of the Recall Transaction and the subsequent integration of Recall’s operations into 

our operations, we again reassessed our intentions regarding the indefinite reinvestment of such undistributed earnings of our 
foreign subsidiaries outside the United States (the “2016 Indefinite Reinvestment Assessment”). As a result of the 2016 
Indefinite Reinvestment Assessment, 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 and, therefore, during 2016, we 
recognized a decrease in our provision for income taxes from continuing operations in the amount of $3.3 million, representing 
the reversal of previously recognized incremental foreign withholding taxes on the earnings of such unconverted foreign TRSs. 
As a result of the 2016 Indefinite Reinvestment Assessment, we no longer provide incremental foreign withholding taxes on the 
retained book earnings of these unconverted foreign TRSs, which was approximately $230.0 million as of December 31, 2017. 
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 in limited instances; however, such future repatriations will 
require distribution in accordance with REIT distribution rules, and any such distribution may then be taxable, as appropriate, 
at the stockholder level. We continue, however, to provide for incremental foreign withholding taxes on net book over outside 
basis differences related to the earnings of our foreign QRSs and certain other foreign TRSs (excluding unconverted foreign 
TRSs).

Tax Reform

On December 22, 2017, the Tax Reform Legislation was enacted into law in the United States. The Tax Reform 

Legislation amends the Code to reduce tax rates and modify policies, credits and deductions for businesses and individuals. The 
following summarizes certain components of the Tax Reform Legislation that had an impact on our results of operations for the 
taxable year ended December 31, 2017, or that we expect could have an impact on our results of operations in future taxable 
periods:

a.  Corporate Tax Rate Reduction

The Tax Reform Legislation reduced the United States corporate federal income tax rate from 35% to 21% for taxable 

years beginning after December 31, 2017 (the “U.S. Federal Rate Reduction”). Our deferred tax assets and liabilities are 
measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are 
expected to be realized or settle. As a result of the Tax Reform Legislation being enacted prior to December 31, 2017, our 
consolidated balance sheet as of December 31, 2017 reflects the revaluation of our deferred tax assets and liabilities based upon 
the U.S. Federal Rate Reduction. During the fourth quarter of 2017, we recorded a discrete tax benefit of approximately $4.7 
million, representing the revaluation of our deferred tax assets and liabilities as a result of the U.S. Federal Rate Reduction 
included in the Tax Reform Legislation.

Beginning with our taxable year ending December 31, 2018, we expect that the U.S. Federal Rate Reduction will both 

increase the after-tax earnings of our TRSs and result in a lower overall structural tax rate (or adjusted effective tax rate) 
compared to our taxable year ended December 31, 2017. 

b.  Deemed Repatriation Transition Tax

The Tax Reform Legislation imposes a transition tax (the “Deemed Repatriation Transition Tax”) on a mandatory deemed 
repatriation of post-1986 undistributed foreign earnings and profits not previously subject to United States tax as of November 
2, 2017 or December 31, 2017, whichever is greater (the “Undistributed E&P”) as of the last taxable year beginning before 
January 1, 2018. The Deemed Repatriation Transition Tax varies depending on whether the Undistributed E&P is held in liquid 
(as defined in the Tax Reform Legislation) or non-liquid assets. A participation deduction against the deemed repatriation will 
result in a Deemed Repatriation Transition Tax on Undistributed E&P of 15.5% if held in cash and liquid assets and 8% if held 
in non-liquid assets. The Deemed Repatriation Transition Tax applies regardless of whether or not an entity has cash in its 
foreign subsidiaries and regardless of whether the entity actually repatriates the Undistributed E&P back to the United States.

Our current estimate of the amount of Undistributed E&P deemed repatriated under the Tax Reform Legislation in our 

taxable year ending December 31, 2017 is approximately $186.0 million (the “Estimated Undistributed E&P”). We have opted 
to include the full amount of Estimated Undistributed E&P in our 2017 taxable income, rather than spread it over eight years 
(as permitted by the Tax Reform Legislation). Accordingly, included in our REIT taxable income for 2017 is approximately 
$82.0 million related to the deemed repatriation of Undistributed E&P (the “Deemed Repatriation Taxable Income”). 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 gains) each year to our stockholders. 

We have considered the Estimated Undistributed E&P when determining the federal income tax characterization of our 
2017 dividends (see Note 13 to Notes to Consolidated Financial Statements included in this Annual Report). As a result of the 
inclusion of the Estimated Undistributed E&P in 2017, $0.531000 per share, or approximately 90%, of the cash dividend paid 
on January 2, 2018 with a record date of December 15, 2017 (the “January 2018 Distribution”) has been treated as a 2017 
distribution for United States federal income tax purposes and $0.056500, or approximately 10%, of the January 2018 
Distribution will be treated as a 2018 distribution for United States federal income tax purposes. 

Our current estimate of Estimated Undistributed E&P includes certain assumptions made by us regarding the cumulative 

earnings and profits of our foreign subsidiaries, as well as the characterization of such Estimated Undistributed E&P (liquid 
versus non-liquid assets). In 2018, we will perform additional analysis to determine the actual amount of Undistributed E&P 
associated with our foreign subsidiaries, as well as the characterization of such Undistributed E&P. We do not believe this will 
have an impact on our provision for income taxes or our qualification as a REIT. However, it may impact our shareholder 
dividend reporting.

52

c.  Full Expensing of Qualified Property

The Tax Reform Legislation permits us to expense 100% of the cost of qualified property placed in service after 
September 27, 2017 and before January 1, 2023 (the “Full Expensing Provision”). The Full Expensing Provision is phased 
down by 20% per calendar year beginning in 2023, with normal depreciation rules applicable after that. We elected to fully 
expense qualified property placed in service after September 27, 2017. Our application of the Full Expensing Provision in our 
2017 taxable year resulted in a $3.8 million reduction of 2017 taxable income, resulting in a reduction of cash taxes of 
approximately $1.3 million.

Beginning with our taxable year ending December 31, 2018, we expect the Full Expensing Provision to result in higher 

deductions being available to us, primarily associated with our United States TRSs, for purposes of determining our United 
States federal taxable income, which we expect will result in lower overall normalized cash taxes compared to our taxable year 
ended December 31, 2017. 

d.  Global Intangible Low-Taxed Income

For taxable years beginning after December 31, 2017, the Tax Reform Legislation introduces new provisions intended to 

prevent the erosion of the United States federal income tax base through the taxation of certain global intangible low-taxed 
income (“GILTI”). GILTI creates a new requirement that certain income earned by controlled foreign corporations (“CFCs”) 
must be included currently in the gross income of the CFC’s United States tax resident shareholder. Generally, GILTI is the 
excess of the United States shareholders’ pro rata portion of the income of its foreign subsidiaries over the net deemed tangible 
income return of such subsidiaries. 

GILTI also provides for certain deductions against the inclusion of GILTI in taxable income; however, REITs are not 

eligible for such deductions. Therefore, 100% of our GILTI will be included in our taxable income and will increase the 
required minimum distribution to our stockholders, similar to the Subpart F income inclusion we are subject to today. 

We are currently in the process of developing our estimates of GILTI. Provided that the income associated with GILTI 

will be treated as qualifying income for purposes of the REIT gross income tests that we are required to satisfy, we do not 
expect GILTI to impact our provision for income taxes. However, we do expect GILTI to impact the United States federal 
income tax characterization of dividends that we expect to pay in future taxable years. Please see "Risks Related to our 
Taxation as a REIT" within Item 1A. Risk Factors included in this Annual Report for additional information regarding the 
uncertainty pertaining to income that we are required to recognize on account of the Tax Reform Legislation being treated as 
qualifying income for purposes of the REIT gross income tests that we are required to satisfy.

e.  Interest Deduction Limitation

The Tax Reform Legislation also limits, for certain entities, the deduction for net interest expense to the sum of business 
interest income plus 30% of adjusted taxable income (the “Interest Deduction Limitation”). Adjusted taxable income is defined 
in the Tax Reform Legislation similar to earnings before interest, taxes, depreciation and amortization ("EBITDA") for taxable 
years beginning after December 31, 2017 and before January 1, 2022, and is defined similar to earnings before interest and 
taxes ("EBIT") for taxable years beginning after December 31, 2021. 

The Interest Deduction Limitation does not apply to companies that make an election to be treated as a “real property 
trade or business”. We are currently in the process of determining if we will be subject to the Interest Deduction Limitation, in 
order to determine whether or not to elect to be treated as a “real property trade or business” under the Tax Reform Legislation.

If we do not elect to be treated as a “real property trade or business”, we will remain subject to the Interest Deduction 

Limitation and may be limited in the amount of interest expense we can deduct for United States federal income tax purposes 
beginning in our taxable year ending December 31, 2018. If we do elect to be treated as a “real property trade or business”, we 
will be required to utilize the alternative depreciation system (“ADS”) for our real property. The use of the ADS may result in a 
tax accounting method change, which could require us to pay additional cash taxes in future taxable years.

(1)  Constant currency growth rates are calculated by translating the 2016 results at the 2017 average exchange rates and 

the 2015 results at the 2016 average exchange rates.

(2)  Our internal 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. 
The revenues generated by Recall have been integrated with our existing revenues and it is impracticable for us to 
determine actual Recall revenue contribution for the applicable periods. Therefore, our internal revenue growth rates 
exclude the impact of revenues associated with the Recall Transaction based upon forecasted or budgeted Recall 
revenues beginning in the third quarter of 2016 through the one-year anniversary of the Recall Transaction. Our 
internal revenue growth rate includes the impact of acquisitions of customer relationships.

Storage Rental Revenues

In the year ended December 31, 2017, the increase in reported consolidated storage revenue was driven by the favorable 

impact of acquisitions/divestitures, consolidated internal storage rental revenue growth and favorable fluctuations in foreign 
currency exchange rates. The net impact of acquisitions/divestitures contributed 6.5% to the reported storage rental revenue 
growth rate for the year ended December 31, 2017 compared to the prior year period, primarily driven by our acquisition of 
Recall. Internal storage rental revenue growth of 3.9% in the year ended December 31, 2017 compared to the prior year period 
was driven by internal storage rental revenue growth of 3.2% in our North American Records and Information Management 
Business segment, due to net price increases, as well as internal storage rental revenue growth of 2.4%, 2.3% and 6.6% in our 
North American Data Management Business, Western European Business and Other International Business segments, 
respectively, primarily driven by volume increases. Excluding the impact of acquisitions/divestitures, global records 
management net volumes as of December 31, 2017 increased by 1.1% over the ending volume as of December 31, 2016. 
Global records management reported net volumes, including acquisitions/divestitures, as of December 31, 2017 increased by 
1.7% over the ending volume at December 31, 2016, supported by volume increases of 1.7% and 6.0% in our Western 
European Business and Other International Business segments, respectively. Ending net volume including acquisitions/
divestitures at December 31, 2017 in our North American Records and Information Management Business segment was flat 
compared to the ending net volume at December 31, 2016 due to customers generating fewer documents requiring storage. 
Foreign currency exchange rate fluctuations increased our reported storage rental revenue growth rate for the year ended 
December 31, 2017 by 0.6%, compared to the prior year period.

In the year ended December 31, 2016, the net impact of acquisitions/divestitures and consolidated internal storage rental 

revenue growth were partially offset by unfavorable fluctuations in foreign currency exchange rates compared to the year ended 
December 31, 2015. The net impact of acquisitions/divestitures contributed 16.8% to the reported storage rental revenue 
growth rate for the year ended December 31, 2016 compared to the prior year period, primarily driven by our acquisition of 
Recall. Internal storage rental revenue growth of 2.3% in the year ended December 31, 2016 compared to the year ended 
December 31, 2015 was driven by internal storage rental revenue growth of 1.0%, 1.9%, 0.8% and 8.5% in our North American 
Records and Information Management Business, North American Data Management Business, Western European Business and 
Other International Business segments, respectively, primarily driven by volume increases. Excluding the impact of 
acquisitions, global records management net volumes as of December 31, 2016 increased by 1.7% over the ending volume as 
of December 31, 2015. These increases were partially offset by the impact of foreign currency exchange rate fluctuations, 
which decreased our reported storage rental revenue growth rate for the year ended December 31, 2016 by 2.5%, compared to 
the prior year period. Global records management reported net volumes, including the impact of acquisitions, as of December 
31, 2016 increased by 26.3% over the ending volume at December 31, 2015, supported by volume increases across each of our 
reportable operating segments, primarily associated with the acquisition of Recall.

Service Revenues

In the year ended December 31, 2017, the increase in reported consolidated service revenue was driven by the favorable 

impact of acquisitions/divestitures and favorable fluctuations in foreign currency exchange rates, partially offset by negative 
internal service revenue growth compared to the year ended December 31, 2016. The net impact of acquisitions/divestitures 
contributed 6.9% to the reported service revenue growth rate for the year ended December 31, 2017, compared to the prior year 
period, primarily driven by our acquisition of Recall. Foreign currency exchange rate fluctuations increased our reported 
service revenue growth for the year ended December 31, 2017 by 0.7%, compared to the prior year period. Internal service 
revenue growth was negative 0.3% for the year ended December 31, 2017, compared to the prior year period. The negative 
internal service revenue growth for the year ended December 31, 2017 reflects continued declines in retrieval/re-file activity 
and the related decrease in transportation revenues within our North American Records and Information Management Business 
and Western European Business segments as well as declines in service revenue activity levels in our North American Data 
Management Business segment, as the storage business becomes more archival in nature, and declines in project activity in our 
Other International Business segment. These declines were partially offset by growth in secure shredding revenues in our North 
American Records and Information Management Business segment, in part due to higher recycled paper prices and increased 
project activity in our Western European Business segment. 

In the year ended December 31, 2016, the net impact of acquisitions/divestitures was partially offset by negative 
consolidated internal service revenue growth and unfavorable fluctuations in foreign currency exchange rates compared to the 
year ended December 31, 2015. The net impact of acquisitions/divestitures contributed 20.5% to the reported service revenue 
growth rate for the year ended December 31, 2016 compared to the year ended December 31, 2015, primarily driven by our 
acquisition of Recall. Internal service revenue growth was negative 0.6% for the year ended December 31, 2016, compared to 
the prior year period. The negative internal service revenue growth for the year ended December 31, 2016 reflects reduced 
retrieval/re-file activity and a related decrease in transportation revenues within our North American Records and Information 
Management Business and Western European Business segments, as well as continued declines in service revenue activity 
levels in our North American Data Management Business segment, as the storage business becomes more archival in nature. In 
the North American Records and Information Management Business segment, our internal service revenue growth rate of 1.0% 
for the year ended December 31, 2016 was driven by special project revenue recognized in the first quarter of 2016 and growth 
in secure shredding revenues, as well as the stabilization in recent periods of the decline in retrieval/re-file activity and the 
related decrease in transportation revenues. Our internal service revenue growth rates of negative 10.2% and negative 5.6% for 
the year ended December 31, 2016 in our North American Data Management and Western European Business segments, 
respectively, are reflecting more recent reductions in retrieval/re-file activity and the related decrease in transportation 
revenues.

Total Revenues

For the reasons stated above, our reported consolidated revenues increased $334.1 million, or 9.5%, to $3,845.6 million 

for the year ended December 31, 2017 from $3,511.5 million for the year ended December 31, 2016. The net impact of 
acquisitions/divestitures contributed 6.6% to the reported consolidated revenue growth rate for the year ended December 31, 
2017 compared to the prior year period, primarily driven by our acquisition of Recall. Consolidated internal revenue growth 
was 2.3% in the year ended December 31, 2017 compared to the prior year period. Foreign currency exchange rate fluctuations 
increased our reported consolidated revenue by 0.6% in the year ended December 31, 2017 compared to the prior year period, 
primarily due to the strengthening of the Australian dollar, Brazilian real, Canadian dollar and the Euro against the United 
States dollar, somewhat offset by the weakening of the British pound sterling against the United States dollar, based on an 
analysis of weighted average rates for the comparable periods.

For the reasons stated above, our consolidated revenues increased $503.5 million, or 16.7%, to $3,511.5 million for the 
year ended December 31, 2016 from $3,008.0 million for the year ended December 31, 2015. The net impact of acquisitions/
divestitures contributed 18.2% to the reported consolidated revenue growth rates for the year ended December 31, 2016 
compared to the prior year period, primarily driven by our acquisition of Recall. Consolidated internal revenue growth was 
1.2% in the year ended December 31, 2016 compared to the prior year period. These increases were partially offset by the 
impact of foreign currency exchange rate fluctuations, which decreased our reported consolidated revenue by 2.7% in the year 
ended December 31, 2016 compared to the prior year period, primarily due to the weakening of the Australian dollar, Brazilian 
real, British pound sterling, Canadian dollar and the Euro against the United States dollar, based on an analysis of weighted 
average rates for the comparable periods.

We expect our consolidated internal storage rental revenue growth rate for 2018 to be approximately 3.0% to 3.5%. 

During the past eight quarters, our internal storage rental revenue growth rate has ranged between 2.1% and 4.8%. 
Consolidated internal storage rental revenue growth and consolidated total internal revenue growth benefited by approximately 
0.8% and 0.5%, respectively, in the second quarter of 2017, from a $4.2 million customer termination fee in our Global Data 
Center Business segment. Our internal storage rental revenue growth rates have improved over the past two fiscal years, as 
internal storage rental revenue growth for full year 2016 and 2017 was 2.3% and 3.9%, respectively. At various points in the 
economic cycle, internal storage rental revenue growth may be influenced by changes in pricing and volume. In North America, 
internal storage rental revenue growth in 2017 resulted primarily from price increases in our North American Records and 
Information Management Business segment as well as internal storage rental revenue growth in our North American Data 
Management Business segment, although North America volume continues to be flat due to customers generating fewer 
documents requiring storage. In 2018, we expect this trend of flat to modestly decreasing volume growth to continue with 
organic growth to come primarily from increased pricing in our North American Records and Information Management 
Business and North American Data Management Business segments and volume growth in our Other International Business 
segment. Within our international portfolio, the Western European Business segment is generating consistent low single-digit 
internal storage rental revenue growth, while the Other International Business segment is producing mid to high single-digit 
internal storage rental revenue growth by capturing the first-time outsourcing trends for physical records storage and 
management in those markets. The internal growth rate for service revenue is inherently more volatile than the internal growth 
rate for storage rental revenues due to the more discretionary nature of certain services we offer, such as large special projects, 
and, as a commodity, the volatility of pricing for recycled paper. These revenues, which are often event-driven and impacted to 
a greater extent by economic downturns as customers defer or cancel the purchase of certain services as a way to reduce their 
short-term costs, may be difficult to replicate in future periods. The internal growth rate for total service revenues over the past 
eight quarters reflects reduced retrieval/re-file activity and a related decrease in transportation revenues within our North 
American Records and Information Management Business and Western European Business segments, as well as continued 
service declines in service revenue activity levels in our North American Data Management Business segment as the storage 
business becomes more archival in nature.

Labor

Labor expenses decreased to 20.4% of consolidated revenues in the year ended December 31, 2017 compared to 21.5% in 

the year ended December 31, 2016. The decrease in labor expenses as a percentage of consolidated revenues was primarily 
driven by an approximately 100 basis point decrease in labor expenses associated with our North American Records and 
Information Management Business segment as a percentage of consolidated revenues, primarily associated with wages and 
benefits growing at a lower rate than revenue, partially attributable to synergies associated with our acquisition of Recall. On a 
constant dollar basis, labor expenses for the year ended December 31, 2017 increased by $24.3 million, or 3.2%, compared to 
the prior year period, primarily driven by our acquisition of Recall.

Labor expenses as a percentage of consolidated revenues were flat during the year ended December 31, 2016 compared to 

the year ended December 31, 2015, as decreases in labor expenses as a percentage of consolidated revenue in our North 
American Records and Information Management Business segment were offset by an increase in labor expenses as a 
percentage of consolidated revenue in our Other International Business segment. The 75 basis point decrease in labor expenses 
as a percentage of consolidated revenue associated with our North American Records and Information Management Business 
segment was primarily associated with wages and benefits growing at a lower rate than revenue, partially attributable to 
synergies associated with our acquisition of Recall. The 52 basis point increase in labor expenses as a percentage of 
consolidated revenue associated with our Other International Business segment was primarily associated with increased wages 
and benefits. Labor expenses for the year ended December 31, 2016 increased by $126.4 million, or 20.1%, on a constant dollar 
basis compared to the prior year period, primarily driven by our acquisition of Recall.

Facilities

Facilities expenses increased to 15.1% of consolidated revenues in the year ended December 31, 2017 compared to 
14.9% in the year ended December 31, 2016. The 20 basis points increase in facilities expenses as a percentage of consolidated 
revenues was primarily driven by an increase in rent expense as a result of the acquisition of Recall, as Recall's real estate 
portfolio contains a more significant proportion of leased facilities than our real estate portfolio as it existed prior to the closing 
of the Recall Transaction. On a constant dollar basis, facilities expenses for the year ended December 31, 2017 increased by 
$55.0 million, or 10.4%, compared to the prior year period, primarily driven by our acquisition of Recall.

Facilities expenses increased to 14.9% of consolidated revenues for the year ended December 31, 2016 compared to 
14.2% for the year ended December 31, 2015. The 70 basis point increase in facilities expenses as a percentage of consolidated 
revenues was driven primarily by an increase in rent expense as a result of the acquisition of Recall, as Recall's real estate 
portfolio contains a more significant proportion of leased facilities than our real estate portfolio as it existed prior to the closing 
of the Recall Transaction, partially offset by a decrease in other facilities costs. The decrease in other facilities costs was 
primarily driven by lower utilities and building maintenance costs associated with our North American Records and 
Information Management Business segment, as well as lower property taxes associated with our Western European Business 
segment. Facilities expenses for the year ended December 31, 2016 increased by $107.6 million, or 25.9%, on a constant dollar 
basis compared to the prior year period, primarily driven by our acquisition of Recall.

Transportation

Transportation expenses decreased to 3.7% of consolidated revenues for the year ended December 31, 2017 compared to 
3.8% for the year ended December 31, 2016. The decrease in transportation expenses as a percentage of consolidated revenues 
was driven by a decrease in vehicle lease expense, primarily associated with our North American Records and Information 
Management Business segment, partially offset by an increase in third party carrier costs as a percentage of consolidated 
revenue, primarily associated with our Other International Business segment. On a constant dollar basis, transportation 
expenses for the year ended December 31, 2017 increased by $9.2 million, or 6.9%, compared to the prior year period, 
primarily driven by our acquisition of Recall. 

Transportation expenses increased to 3.8% of consolidated revenues for the year ended December 31, 2016 compared to 
3.4% for the year ended December 31, 2015. The increase in transportation expenses as a percentage of consolidated revenues 
was driven by a 40 basis point increase in third party carrier costs as a percentage of consolidated revenues, primarily 
associated with our Other International Business segment. Transportation expenses for the year ended December 31, 2016 
increased by $33.3 million, or 33.6%, on a constant dollar basis compared to the prior year period, primarily driven by our 
acquisition of Recall.

Product Cost of Sales and Other

Product cost of sales and other, which includes cartons, media and other service, storage and supply costs and is highly 
correlated to service revenue streams, particularly project revenues, decreased to 4.0% of consolidated revenues for the year 
ended December 31, 2017 compared to 4.1% in the year ended December 31, 2016. The decrease in product cost of sales and 
other was driven by special project costs. On a constant dollar basis, product cost of sales and other increased by $9.5 million, 
or 6.5%, compared to the prior year period, primarily driven by our acquisition of Recall.

For the year ended December 31, 2016, product cost of sales and other increased by $32.1 million, or 28.5%, on a 

constant dollar basis compared to the prior year period, primarily driven by our acquisition of Recall.

Recall Costs

Recall Costs included in cost of sales were $20.5 million for the year ended December 31, 2017, and primarily consisted 

of employee severance costs and facility integration costs including labor, maintenance, transportation and other costs related to 
building moves and consolidation. Recall Costs included in cost of sales were $12.0 million for the year ended December 31, 
2016, and primarily consisted of employee severance costs.

compared to 14.4% for the year ended December 31, 2016. The decrease in general and administrative expenses as a 
percentage of consolidated revenues was driven mainly by a decrease in compensation expense, partially attributable to the 
Transformation Initiative and synergies associated with our acquisition of Recall, partially offset by an increase in professional 
fees associated with innovation initiatives. On a constant dollar basis, general and administrative expenses for the year ended 
December 31, 2017 increased by $14.4 million, or 2.8%, compared to the prior year period, primarily driven by our acquisition 
of Recall.

Sales, Marketing & Account Management

Sales, marketing and account management expenses decreased to 6.6% of consolidated revenues for the year ended 
December 31, 2017 compared to 6.8% for the year ended December 31, 2016. The decrease was driven by a decrease in sales, 
marketing and account management expenses in our North American Records and Information Business segment primarily 
associated with wages and benefits growing at a lower rate than revenue, partially attributable to the Transformation Initiative 
and synergies associated with our acquisition of Recall. On a constant dollar basis, sales, marketing and account management 
expenses for the year ended December 31, 2017 increased by $14.4 million, or 6.0%, compared to the prior year period, 
primarily driven by our acquisition of Recall.

Sales, marketing and account management expenses decreased to 6.8% of consolidated revenues during the year ended 

December 31, 2016 compared to 7.1% in 2015. The decrease was driven by a decrease in sales, marketing and account 
management expenses in our North American Records and Information Management Business segment, primarily associated 
with compensation growing at a lower rate than revenue, partially attributable to the Transformation Initiative and synergies 
associated with our acquisition of Recall. Sales, marketing and account management expenses for the year ended December 31, 
2016 increased by $28.9 million, or 13.8%, on a constant dollar basis compared to the prior year period, primarily driven by 
our acquisition of Recall.

Information Technology

Information technology expenses increased to 3.4% of consolidated revenues for the year ended December 31, 2017 

compared to 3.3% for the year ended December 31, 2016. Information technology expenses as a percentage of consolidated 
revenues reflect an increase in professional fees and software maintenance and license fees, partially offset by lower 
compensation expense, partially attributable to the Transformation Initiative and synergies associated with our acquisition of 
Recall. On a constant dollar basis, information technology expenses for the year ended December 31, 2017 increased by $15.0 
million, or 12.8%, compared to the prior year period, primarily driven by our acquisition of Recall.

Information technology expenses as a percentage of consolidated revenue were flat during the year ended December 31, 

2016 compared to the year ended December 31, 2015, as increases in information technology expenses as a percentage of 
consolidated revenues in our Corporate and Other Business segment were offset by decreases in information technology 
expenses as a percentage of consolidated revenue in our North American Records and Information Management Business and 
Western European Business segments. Information technology expenses in our Corporate and Other Business segment 
increased due mainly to higher software maintenance and license fees while decreases in information technology expenses 
across our North American Records and Information Management and Western European Business segments were primarily 
due to decreased compensation expense. Information technology expenses for the year ended December 31, 2016 increased by 
$19.7 million, or 20.3%, on a constant dollar basis compared to the prior year period, primarily driven by our acquisition of 
Recall.

Bad Debt Expense

We maintain an allowance for doubtful accounts that is calculated based on our past loss experience, current and prior 

trends in our aged receivables, current economic conditions, and specific circumstances of individual receivable balances. We 
continue to monitor our customers' payment activity and make adjustments based on their financial condition and in light of 
historical and expected trends. Consolidated bad debt expense for the year ended December 31, 2017 increased to 0.4% of 
consolidated revenues for the year ended December 31, 2017 compared to 0.2% for the year ended December 31, 2016.  On a 
constant dollar basis, bad debt expenses for the year ended December 31, 2017 increased by $6.1 million, or 70.7%, compared 
to the prior year period primarily due to higher bad debt expense in our Other International Business segment.

Consolidated bad debt expense for the year ended December 31, 2016 decreased to 0.2% of consolidated revenues for the 
year ended December 31, 2016 compared to 0.5% for the year ended December 31, 2015. Bad debt expenses for the year ended 
December 31, 2016 decreased by $6.6 million, or 43.1%, on a constant dollar basis compared to the prior year period. 

Recall Costs

Recall Costs included in selling, general and administrative expenses were $64.4 million and $120.0 million for the years 

ended December 31, 2017 and 2016, respectively, and primarily consisted of advisory and professional fees, as well as 
severance costs. Recall Costs included in selling, general and administrative expenses were $47.0 million for the year ended 
December 31, 2015, and primarily consisted of advisory and professional fees.

61

Depreciation and Amortization

Depreciation expense increased $40.8 million, or 11.2%, on a reported dollar basis for the year ended December 31, 2017 

compared to the year ended December 31, 2016, primarily due to the increased depreciation of property, plant and equipment 
acquired in the Recall Transaction. See Note 2.f. 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. Depreciation 
expense increased $64.3 million, or 21.3%, on a reported dollar basis for the year ended December 31, 2016 compared to the 
year ended December 31, 2015, primarily due to the increased depreciation of property, plant and equipment acquired in the 
Recall Transaction.

Amortization expense increased $29.3 million, or 33.7%, on a reported dollar basis for the year ended December 31, 2017 
compared to the year ended December 31, 2016, primarily due to the increased amortization of customer relationship intangible 
assets acquired in the Recall Transaction, which are amortized over a weighted average useful life of 13 years. Amortization 
expense increased $42.5 million, or 96.2%, on a reported dollar basis for the year ended December 31, 2016 compared to the 
year ended December 31, 2015, primarily due to the increased amortization of customer relationship intangible assets acquired 
in the Recall Transaction.

OTHER EXPENSES, NET

Interest Expense, Net (in thousands)

Interest expense, net increased $42.9 million to $353.6 million for the year ended December 31, 2017 from $310.7 

million for the year ended December 31, 2016. Interest expense, net increased $46.8 million to $310.7 million for the year 
ended December 31, 2016 from $263.9 million for the year ended December 31, 2015. The increase in interest expense, net in 
each of the years ended December 31, 2017 and 2016 compared to the prior year period was the result of higher average debt 
outstanding during those periods. Our weighted average interest rate was 5.0% and 5.2% at December 31, 2017 and 2016, 
respectively. See Note 4 to Notes to Consolidated Financial Statements included in this Annual Report for additional 
information regarding our indebtedness.

We recorded net foreign currency transaction losses of $43.2 million in the year ended December 31, 2017, based on 
period-end exchange rates. These losses resulted primarily from the impact of changes in the exchange rate of each of the 
British pound sterling, Canadian dollar and Euro against the United States dollar compared to December 31, 2016 on our 
intercompany balances with and between certain of our subsidiaries and Euro denominated bonds issued by IMI (the Euro 
Notes, as defined below). These losses were partially offset by gains resulting primarily from the impact of changes in the 
exchange rate of each of the Australian dollar, Mexican peso and Russian ruble against the United States dollar compared to 
December 31, 2016 on our intercompany balances with and between certain of our subsidiaries, as well as Euro forward 
contracts.

We recorded net foreign currency transaction losses of $20.4 million in the year ended December 31, 2016, based on 
period-end exchange rates. These losses resulted primarily from the impact of changes in the exchange rate of each of the 
Argentine peso, British pound sterling and Mexican peso against the United States dollar compared to December 31, 2015 on 
our intercompany balances with and between certain of our subsidiaries. These losses were partially offset by gains resulting 
primarily from the impact of changes in the exchange rate of each of the Brazilian real, Euro and Russian ruble against the 
United States dollar compared to December 31, 2015 on our intercompany balances with and between certain of our 
subsidiaries.

We recorded net foreign currency transaction losses of $70.9 million in the year ended December 31, 2015, based on 
period-end exchange rates. These losses resulted primarily from the impact of changes in the exchange rate of each of the 
Argentine peso, Brazilian real, Euro, Russian ruble and Ukrainian hryvnia against the United States dollar compared to 
December 31, 2014 on our intercompany balances with and between certain of our subsidiaries, as well as Euro forward 
contracts. These losses were partially offset by gains resulting primarily from the impact of a change in the exchange rate of the 
British pound sterling against the United States dollar compared to December 31, 2014 on our intercompany balances with and 
between certain of our subsidiaries, as well as a change in the exchange rate of the Euro against the United States dollar 
compared to December 31, 2014 on Euro denominated bonds issued by IMI.

Debt Extinguishment Expense

During the year ended December 31, 2017, we recorded a debt extinguishment charge of $78.4 million primarily related 
to the early extinguishment of (i) the 6% Notes due 2020, (ii) the CAD Notes due 2021 and (iii) the GBP Notes due 2022 (each 
as defined and described more fully in Note 4 to Notes to Consolidated Financial Statements included in this Annual Report), 
consisting of the write-off of unamortized deferred financing costs and call premiums. During the year ended December 31, 
2016, we recorded a debt extinguishment charge of $9.3 million related to the termination of the Bridge Facility (as defined and 
described more fully in Note 4 to Notes to Consolidated Financial Statements included in this Annual Report), which primarily 
consists of the write-off of unamortized deferred financing costs. During the year ended December 31, 2015, we recorded a 
debt extinguishment charge of $27.3 million related to (i) the refinancing of the Credit Agreement in the third quarter of 2015 
and (ii) the early extinguishment of the 63/4% Euro Senior Subordinated Notes due 2018, 73/4% Senior Subordinated Notes due 
2019 and the remaining portion outstanding of the 83/8% Senior Subordinated Notes due 2021 in the fourth quarter of 2015. 
This charge consists of call premiums, original issue discounts and unamortized deferred financing costs.

Other, Net

Other, net in the year ended December 31, 2017 includes a gain of $38.9 million associated with the Russia and Ukraine 
Divestment (see Note 14 to Notes to Consolidated Financial Statements included in this Annual Report). Other, net in the year 
ended December 31, 2016 includes a charge of $15.4 million associated with the loss on disposal of the Australia Divestment 
Business and a charge of $1.4 million associated with the loss on disposal of the Iron Mountain Canadian Divestments, 
partially offset by $0.8 million of gains associated with a deferred compensation plan we sponsor. Other, net in the year ended 
December 31, 2015 consisted primarily of $0.6 million of losses related to the write-down of certain investments.

Provision (Benefit) for Income Taxes

Our effective tax rates for the years ended December 31, 2015, 2016 and 2017 were 23.3%, 30.6% and 12.0%, 
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 former federal statutory rate of 35.0% and our overall effective tax rate for the 

year ended December 31, 2015 were the benefit derived from the dividends paid deduction of $51.6 million and an out-of-
period tax adjustment ($9.0 million tax benefit) recorded during the third quarter to correct the valuation of certain deferred tax 
assets associated with the REIT conversion that occurred in 2014, partially offset by valuation allowances on certain of our 
foreign net operating losses of $33.5 million, primarily related to our foreign subsidiaries in Argentina, Brazil, France and 
Russia.

The primary reconciling items between the former federal statutory tax rate of 35.0% and our overall effective tax rate for 
the year ended December 31, 2016 were the benefit derived from the dividends paid deduction of $18.5 million and the impact 
of differences in the tax rates at which our foreign earnings are subject resulting in a tax benefit of $13.3 million, partially 
offset by valuation allowances on certain of our foreign net operating losses of $7.7 million.

63

The primary reconciling items between the former federal statutory tax rate of 35.0% and our overall effective tax rate for 

the year ended December 31, 2017 were the benefit derived from the dividends paid deduction of $78.9 million, the impact of 
differences in the tax rates at which our foreign earnings are subject resulting in a tax benefit of $11.9 million, a release of 
valuation allowances on certain of our foreign net operating losses of $4.3 million as a result of the merger of certain of our 
foreign subsidiaries, partially offset by the impact of the Tax Reform Legislation of $24.8 million (reflecting the impact of the 
Deemed Repatriation Transition Tax, partially offset by the impact of the U.S. Federal Rate Reduction).

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.

Gain on Sale of Real Estate, Net of Tax

Consolidated gain on sale of real estate, net of tax for the year ended December 31, 2017 was $1.6 million and consisted 
primarily of the sale of land and a building in the United States for net proceeds of approximately $12.7 million. Consolidated 
gain on sale of real estate, net of tax for the year ended December 31, 2016 was $2.2 million, associated with the sale of certain 
land and buildings in North America. Consolidated gain on sale of real estate, net of tax for the year ended December 31, 2015 
was $0.9 million, associated with the sale of a building in the United Kingdom.

INCOME (LOSS) FROM DISCONTINUED OPERATIONS 

(Loss) income from discontinued operations, net of tax was $(6.3) million and $3.4 million for the years ended 

December 31, 2017 and 2016, respectively, primarily related to the operations of the Recall Divestments (as defined in Note 6 
to Notes to Consolidated Financial Statements included in this Annual Report).

NONCONTROLLING INTERESTS

Net income attributable to noncontrolling interests resulted in a decrease in net income attributable to IMI of $1.6 
million, $2.4 million and $2.0 million for the years ended December 31, 2017, 2016 and 2015, respectively. These amounts 
represent our noncontrolling partners' share of earnings/losses in our majority-owned international subsidiaries that are 
consolidated in our operating results.

Segment Analysis (in thousands)

During the fourth quarter of 2017, as a result of changes in the management of our entertainment storage and services 

business, we reassessed the composition of our reportable operating segments. As a result of this reassessment, we determined 
that our entertainment storage and services businesses in the United States and Canada, which were previously included within 
our North American Data Management Business segment, were now being managed in conjunction with our entertainment 
storage and services businesses in France, Hong Kong, the Netherlands and the United Kingdom (the majority of which were 
acquired in the third quarter of 2017 as part of the Bonded Transaction) as a component of our Adjacent Businesses operating 
segment which is included within our Corporate and Other Business reportable operating segment. 

Additionally, during the fourth quarter of 2017, we determined that our global data center business was now being 
managed as a separate reportable operating segment, rather than as a component of our Adjacent Businesses operating segment. 
We now present our Global Data Center Business operating segment as a separate reportable operating segment.  

As a result of the changes noted above, previously reported segment information has been restated to conform to the 
current presentation. See Note 9 to Notes to Consolidated Financial Statements included in this Annual Report for a description 
of our reportable operating segments.

For the year ended December 31, 2017, reported revenue in our North American Records and Information Management 

Business segment increased 6.2% compared to the year ended December 31, 2016, primarily due to the favorable net impact of 
acquisitions/divestitures and internal revenue growth. The net impact of acquisitions/divestitures contributed 3.6% to the 
reported revenue growth rate in our North American Records and Information Management Business segment for the year 
ended December 31, 2017 compared to the prior year period, driven by our acquisition of Recall. Internal revenue growth of 
2.4% in the year ended December 31, 2017 was primarily the result of (i) internal storage rental revenue growth of 3.2% in the 
year ended December 31, 2017, due to net price increases and (ii) internal service revenue growth of 1.1% in the year ended 
December 31, 2017, driven by growth in secure shredding revenues, in part due to higher recycled paper prices, partially offset 
by a decline in retrieval/re-file activity and the related decrease in transportation revenues. Adjusted EBITDA margin increased 
290 basis points during the year ended December 31, 2017 compared to the year ended December 31, 2016, primarily driven by 
a decrease in wages and benefits as a percentage of segment revenue, partially attributable to the Transformation Initiative and 
synergies associated with our acquisition of Recall, as well as lower professional fees.

For the year ended December 31, 2016, reported revenue in our North American Records and Information Management 
Business segment increased 8.7% compared to the year ended December 31, 2015. In the year ended December 31, 2016, the 
net impact of acquisitions/divestitures and internal revenue growth were partially offset by unfavorable fluctuations in foreign 
currency exchange rates compared to the year ended December 31, 2015. The net impact of acquisitions/divestitures 
contributed 8.2% to the reported revenue growth rate in our North American Records and Information Management Business 
segment for the year ended December 31, 2016 compared to the prior year period, primarily driven by our acquisition of 
Recall. The internal revenue growth in the year ended December 31, 2016 was primarily the result of internal storage rental 
revenue growth of 1.0% in the year ended December 31, 2016 compared to the year ended December 31, 2015, as well as 
internal service revenue growth of 1.0% in the year ended December 31, 2016 compared to the year ended December 31, 2015, 
which was driven by special project revenue recognized in the first quarter of 2016 and growth in secure shredding revenues, as 
well as the stabilization in recent periods of the decline in retrieval/re-file activity and the related decrease in transportation 
revenues. Adjusted EBITDA margin decreased 10 basis points during the year ended December 31, 2016 compared to the year 
ended December 31, 2015, primarily driven by increased wages and benefits, rent expense and building maintenance and 
transportation costs, partially offset by a decrease in selling, general and administrative expenses as a percentage of segment 
revenues, primarily associated with wages and benefits growing at a lower rate than revenue, partially attributable to the 
Transformation Initiative and synergies associated with our acquisition of Recall, as well as a decrease in bad debt expense and 
professional fees.

For the year ended December 31, 2017, reported revenue in our North American Data Management Business segment 

increased 2.2%, compared to the year ended December 31, 2016, due to the favorable net impact of acquisitions/divestitures. 
The net impact of acquisitions/divestitures contributed 3.1% to the reported revenue growth rates in our North American Data 
Management Business segment for the year ended December 31, 2017, compared to the prior year period, primarily driven by 
our acquisition of Recall. The negative internal revenue growth of 1.0% for the year ended December 31, 2017 was primarily 
attributable to negative internal service revenue growth of 7.8% for the year ended December 31, 2017 due to continued 
declines in service revenue activity levels as the business becomes more archival in nature, partially offset by internal storage 
rental revenue growth of 2.4% in the year ended December 31, 2017, primarily attributable to volume increases. Adjusted 
EBITDA margin decreased 160 basis points during the year ended December 31, 2017 compared to the year ended 
December 31, 2016, primarily driven by an increase in selling, general and administrative expenses, partially attributable to 
investments associated with product management and development.

For the year ended December 31, 2016, reported revenue in our North American Data Management Business segment 

increased 4.1% compared to the year ended December 31, 2015. In the year ended December 31, 2016, the net impact of 
acquisitions/divestitures was partially offset by negative internal revenue growth and unfavorable fluctuations in foreign 
currency exchange rates compared to the year ended December 31, 2015. The net impact of acquisitions/divestitures 
contributed 6.6% to the reported revenue growth rates in our North American Data Management Business segment for the year 
ended December 31, 2016, compared to the prior year period, primarily driven by our acquisition of Recall. The negative 
internal revenue growth for the year ended December 31, 2016 was primarily attributable to negative internal service revenue 
growth of 10.2% for the year ended December 31, 2016, which was due to continued declines in service revenue activity levels 
as the storage business becomes more archival in nature, partially offset by internal storage rental revenue growth of 1.9% in 
the year ended December 31, 2016, primarily attributable to volume increases. Adjusted EBITDA margin increased 330 basis 
points during the year ended December 31, 2016 compared to the year ended December 31, 2015, primarily driven by lower 
selling, general and administrative expenses, partially attributable to the Transformation Initiative and synergies associated with

For the year ended December 31, 2017, reported revenue in our Western European Business segment increased 10.5%, 

compared to the year ended December 31, 2016, due to the favorable net impact of acquisitions/divestitures and internal

ended December 31, 2017, compared to the prior year period, primarily driven by our acquisition of Recall. Internal revenue 
growth for the year ended December 31, 2017 was 2.0%, primarily attributable to internal storage rental revenue growth of 
2.3% for the year ended December 31, 2017, primarily associated with volume increases. For the year ended December 31, 
2017, foreign currency exchange rate fluctuations decreased our reported revenues for the Western European Business segment

synergies associated with our acquisition of Recall.

For the year ended December 31, 2016, reported revenue in our Western European Business segment increased 14.3% 

compared to the year ended December 31, 2015. In the year ended December 31, 2016, the net impact of acquisitions/ 
divestitures was partially offset by negative internal revenue growth and unfavorable fluctuations in foreign currency exchange 
rates compared to the year ended December 31, 2015. The net impact of acquisitions/divestitures contributed 24.9% to the 
reported revenue growth rates in our Western European Business segment for the year ended December 31, 2016 compared to 
the prior year period, primarily driven by our acquisition of Recall. Internal revenue growth for the year ended December 31, 
2016 was negative 1.7%, primarily attributable to negative internal service revenue growth of 5.6% for the year ended 
December 31, 2016, which was due to reduced retrieval/refile activity and a related decrease in transportation revenues. For the 
year ended December 31, 2016, foreign currency exchange rate fluctuations decreased our reported revenues for the Western 
European Business segment by 8.9% compared to the prior year period due to the weakening of the British pound sterling and 
Euro against the United States dollar. Adjusted EBITDA margin decreased 10 basis points during the year ended December 31, 
2016 compared to the year ended December 31, 2015, primarily driven by an increase in cost of sales as a percentage of 
segment revenue, primarily associated with increased wages and benefits and rent expense, partially offset by a decrease in 
selling, general and administrative expenses as a percentage of segment revenue, primarily associated with wages and benefits 
growing at a lower rate than revenues, partially attributable to the Transformation Initiative and synergies associated with our 
acquisition of Recall, and lower professional fees.

For the year ended December 31, 2017, reported revenue in our Other International Business segment increased 20.3% 
compared to the year ended December 31, 2016, due to the favorable net impact of acquisitions/divestitures, internal revenue 
growth and favorable fluctuations in foreign currency exchange rates. The net impact of acquisitions/divestitures contributed 
13.2% to the reported revenue growth rate in our Other International Business segment for the year ended December 31, 2017 
compared to the prior year period, primarily driven by our acquisition of Recall. Internal revenue growth for the year ended 
December 31, 2017 was 3.7%, supported by 6.6% internal storage rental revenue growth, primarily due to volume increases, 
partially offset by negative 0.7% internal service revenue growth, primarily due to decreased project activity. Foreign currency 
fluctuations in the year ended December 31, 2017 resulted in increased revenue, as measured in United States dollars, of 
approximately 3.4% compared to the prior year period, primarily due to the strengthening of the Australian dollar, Brazilian 
real and Euro against the United States dollar. Adjusted EBITDA margin increased 290 basis points during the year ended 
December 31, 2017 compared to the year ended December 31, 2016, primarily due to a higher margin business in Australia as a 
result of our acquisition of Recall and to a lesser extent, synergies associated with our acquisition of Recall.

For the year ended December 31, 2016, reported revenue in our Other International Business segment increased 54.9% 

compared to the year ended December 31, 2015. In the year ended December 31, 2016, the favorable net impact of 
acquisitions/divestitures and internal revenue growth were partially offset by unfavorable fluctuations in foreign currency 
exchange rates compared to the year ended December 31, 2015. The net impact of acquisitions/divestitures contributed 59.5% 
to the reported revenue growth rates in our Other International Business segment for the year ended December 31, 2016 
compared to the prior year period, primarily driven by our acquisition of Recall. Internal revenue growth for the year ended 
December 31, 2016 was 7.0%, supported by 8.5% internal storage rental revenue growth. Foreign currency fluctuations in the 
year ended December 31, 2016 resulted in decreased revenue, as measured in United States dollars, of approximately 11.6% as 
compared to the prior year period, primarily due to the weakening of the Australian dollar and Brazilian real against the United 
States dollar. Adjusted EBITDA margin increased 520 basis points during the year ended December 31, 2016 compared to the 
year ended December 31, 2015, primarily a result of a decrease in selling, general and administrative expenses as a percentage 
of segment revenue and a decrease in cost of sales as a percentage of segment revenue, primarily associated with compensation 
growing at a lower rate than revenue, as well as lower professional fees.

For the year ended December 31, 2017, reported revenue in our Global Data Center Business segment increased 55.4% 

compared to the year ended December 31, 2016, due to the favorable net impact of acquisitions/divestitures and internal 
revenue growth. The net impact of acquisitions/divestitures contributed 31.4% to the reported revenue growth rate in our 
Global Data Center Business segment for the year ended December 31, 2017 compared to the prior year period, primarily 
driven by our acquisition of Mag Datacenters LLC, which operated Fortrust. Internal revenue growth for the year ended 
December 31, 2017 was 24.0%, supported by 29.0% internal storage rental revenue growth. Internal storage rental revenue 
growth and total internal revenue growth benefited by approximately 14.3% and 13.0%, respectively, from a $4.2 million 
customer termination fee in the second quarter of 2017. Adjusted EBITDA margin increased 430 basis points during the year 
ended December 31, 2017 compared to the year ended December 31, 2016, primarily due to the customer termination fee 
mentioned above.

For the year ended December 31, 2016, reported revenue in our Global Data Center Business segment increased 27.2% 
compared to the year ended December 31, 2015, due to internal revenue growth. Internal revenue growth for the year ended 
December 31, 2016 was 27.2%, supported by 24.7% internal storage rental revenue growth. Adjusted EBITDA margin 
increased 1,580 basis points during the year ended December 31, 2016 compared to the year ended December 31, 2015, 
primarily due to revenue growth.

reconciliation of Adjusted EBITDA to Income (Loss) from Continuing Operations and a discussion of why we believe 
this non-GAAP measure provides relevant and useful information to our current and potential investors.

During the year ended December 31, 2017, Adjusted EBITDA in the Corporate and Other Business segment as a 
percentage of consolidated revenues remained unchanged from the year ended December 31, 2016 at 6.4%. Adjusted EBITDA 
in the Corporate and Other Business segment decreased $19.3 million in the year ended December 31, 2017 compared to the 
year ended December 31, 2016, primarily driven by an increase in information technology expenses associated with our 
acquisition of Recall, professional fees associated with our innovation investments and $3.5 million of costs associated with 
natural disasters, primarily Hurricane Maria, which damaged certain of our facilities in Puerto Rico in the third quarter of 2017.

For the year ended December 31, 2016, Adjusted EBITDA in the Corporate and Other Business segment as a percentage 

of consolidated revenue improved 50 basis points compared to the year ended December 31, 2015. Adjusted EBITDA in the 
Corporate and Other Business segment decreased $18.0 million in the year ended December 31, 2016 compared to the year 
ended December 31, 2015, primarily driven by the impact of the Recall Transaction, partially offset by profitability associated 
with recent acquisitions in our Adjacent Businesses operating segment. Adjusted EBITDA in our Corporate and Other Business 
segment includes approximately $23.3 million of incremental expenses associated with Recall for the year ended December 31, 
2016.

Net cash provided by operating activities from continuing operations was $724.3 million for the year ended 

December 31, 2017 compared to $541.2 million for the year ended December 31, 2016. The $183.0 million year-over-year 
increase in cash flows from operating activities resulted from an increase in net income (including non-cash charges and 
realized foreign exchange losses) of $224.2 million, offset by an increase in cash used in working capital of $41.2 million, 
primarily related to the timing of payments associated with our accounts payable year-over-year. 

Our business requires capital expenditures to maintain our ongoing operations, support our expected revenue growth and 

new products and services, and increase our profitability. These expenditures are included in the cash flows from investing 
activities. The nature of our capital expenditures has evolved over time along with the nature of our business. Our capital goes 
to support business-line growth and our ongoing operations, but we also expend capital to support the development and 
improvement of products and services and projects designed to increase our profitability. These expenditures are generally 
discretionary in nature. Cash paid for our capital expenditures, cash paid for acquisitions (net of cash acquired), acquisition of 
customer relationships and customer inducements during the year ended December 31, 2017 amounted to $343.1 million, 
$219.7 million, $55.1 million and $20.1 million, respectively. For the year ended December 31, 2017, these expenditures were 
primarily funded with cash flows from operations, as well as through borrowings under both our Former Revolving Credit 
Facility and the Revolving Credit Facility (each as defined below), as well as the issuance of the Euro Notes. Excluding capital 
expenditures associated with potential future acquisitions, opportunistic real estate investments and capital expenditures 
associated with the integration of Recall, we expect our capital expenditures on real estate and non-real estate maintenance as 
well as non-real estate investment to be approximately $155.0 million to $165.0 million, our capital expenditures on our data 
center business to be approximately $185.0 million, and our capital expenditures on real estate investment and innovation to be 
approximately $150.0 million to $160.0 million in the year ending December 31, 2018. 

Net cash provided by financing activities from continuing operations was $540.4 million for the year ended December 31, 

2017, consisting primarily of net proceeds of $910.1 million associated with the issuance and retirement of senior notes, net 
proceeds of $516.5 million associated with the Equity Offering and net proceeds of $58.6 million associated with the At The 
Market (ATM) Equity Program, partially offset by the net payments of $512.6 million under both the Former Revolving Credit 
Facility and Revolving Credit Facility (each as defined below), the payment of dividends in the amount of $440.0 million on 
our common stock and the payment of $14.2 million for debt and equity issuance costs. 

As of December 31, 2017, pending their use to finance the purchase price of the IODC Transaction, the net proceeds of 
the Equity Offering, together with the net proceeds from the 51/4% Notes, were used to temporarily repay approximately $807.0 
million of borrowings under our Revolving Credit Facility and invest approximately $524.0 million in money market funds.

 Capital Expenditures

The following table presents our capital spend for 2015, 2016 and 2017 organized by the type of the spending as 

described in the "Our Business Fundamentals" section of "Item 1. Business" included in this Annual Report. We now separately 
identify two additional capital expenditure categories, Innovation and Growth Investment Capital Spend (previously included 
within Non-Real Estate Investment) and Data Center Capital Spend (previously included primarily in Real Estate Investment 
and Non-Real Estate Investment). We have reclassified the categorization of our prior year capital expenditures to conform with

Financial Instruments and Debt

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, 2017 relate to cash and cash equivalents held on deposit with seven global banks and 12 "Triple A" rated money 
market funds, all of which we consider to be large, highly-rated investment-grade institutions. 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 $50.0 million or in any one financial institution to a maximum of $75.0 million. As of December 31, 2017, our 
cash and cash equivalents balance was $925.7 million, which included money market funds amounting to $585.0 million and 
time deposits amounting to $24.5 million.

(8)  Includes (i) real estate mortgages of $20.2 million, (ii) capital lease obligations of $436.3 million, and (iii) other 

various notes and other obligations, which were assumed by us as a result of certain acquisitions, of $193.0 million.

(9)  The Accounts Receivable Securitization Special Purpose Subsidiaries are the obligors under this program.  

(10) Iron Mountain Mortgage Finance I, LLC (the "Mortgage Securitization Special Purpose Subsidiary") is the obligor 

under this program.  

a. Credit Agreement

On August 21, 2017, we entered into a new credit agreement (the "Credit Agreement") which amended and restated our 

then existing credit agreement (the "Former Credit Agreement") which consisted of a revolving credit facility (the "Former 
Revolving Credit Facility") and a term loan (the "Former Term Loan") and was scheduled to terminate on July 6, 2019. The 
Credit Agreement consists of a revolving credit facility (the "Revolving Credit Facility") and a term loan (the "Term Loan"). 
The maximum amount permitted to be borrowed under the Revolving Credit Facility is $1,750.0 million. The original amount 
of the Term Loan was $250.0 million. We have the option to request additional commitments of up to $500.0 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 August 21, 2022, at which point all obligations become 
due. 

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. The Term Loan is to be 
paid in quarterly installments in an amount equal to $3.1 million per quarter, with the remaining balance due on August 21, 
2022.

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, 2017, we had $466.6 million and 
$243.8 million of outstanding borrowings under the Revolving Credit Facility and the Term Loan, respectively. Of the $466.6 
million of outstanding borrowings under the Revolving Credit Facility, $465.0 million was denominated in United States 
dollars and 2.0 million was denominated in Canadian dollars. In addition, we also had various outstanding letters of credit 
totaling $52.8 million under the Revolving Credit Facility. The remaining amount available for borrowing under the Revolving 
Credit Facility as of December 31, 2017, 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 $1,230.6 million (which amount represents the maximum availability as of such date). The average 
interest rate in effect under the Credit Agreement was 3.4% as of December 31, 2017. The average interest rate in effect under 
the Revolving Credit Facility was 3.5% and ranged from 3.4% to 5.5% as of December 31, 2017 and the interest rate in effect 
under the Term Loan as of December 31, 2017 was 3.5%. 

77

The Credit Agreement, our 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 certain other 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 indentures or other 
agreements governing our indebtedness. The Credit Agreement uses EBITDAR-based calculations as the primary measures of 
financial performance, including leverage and fixed charge coverage ratios.

Our leverage and fixed charge coverage ratios under the Former Credit Agreement as of December 31, 2016 and the 

Credit Agreement as of December 31, 2017, as well as our leverage ratio under our indentures as of December 31, 2016 and 
2017 are as follows:

Net total lease adjusted leverage ratio

Net secured debt lease adjusted leverage ratio

Bond leverage ratio (not lease adjusted)

Fixed charge coverage ratio

December 31, 2016
5.7

December 31, 2017

Maximum/Minimum Allowable
5.0 Maximum allowable of 6.5(1)(2)

2.7

5.2

2.4

1.6 Maximum allowable of 4.0

5.8 Maximum allowable of 6.5-7.0(3)(4)

2.1 Minimum allowable of 1.5

______________________________________________________________

(1)  Our maximum allowable net total lease adjusted leverage ratio under the Former Credit Agreement was 6.5. The 

Former Credit Agreement also contained a provision which limited, in certain circumstances, our cash dividends in 
any four consecutive fiscal quarters to 95% of Funds From Operations (as defined in the Former Credit Agreement) 
for such four fiscal quarters or, if greater, the amount that we would be required to pay in order to continue to be 
qualified for taxation as a REIT or to avoid the imposition of income or excise taxes on IMI. This former limitation 
only applied in certain circumstances, including where our net total lease adjusted leverage ratio exceeded 6.0 as 
measured as of the end of the most recently completed fiscal quarter (the “Dividend Limitation Leverage Condition”). 
The Credit Agreement does not contain a Dividend Limitation Leverage Condition. The maximum allowable net total 
lease adjusted leverage ratio under the Credit Agreement is 6.5.

(2)  The definition of the net total lease adjusted leverage ratio was modified under the Credit Agreement. The net total 
lease adjusted leverage ratio at December 31, 2017 was calculated as defined in the Credit Agreement, while the net 
total lease adjusted leverage ratio at December 31, 2016 was calculated as defined in the Former Credit Agreement. 
Had the net total lease adjusted leverage ratio at December 31, 2016 been calculated as defined in the Credit 
Agreement it would have been 5.4.

(3)  The maximum allowable leverage ratio under our indenture for the 47/8% Notes, the GBP Notes due 2025 and the 

51/4% Notes is 7.0. For all other notes the maximum allowable leverage ratio is 6.5. In certain instances, as provided in 
our indentures, we have the ability to incur additional indebtedness that would result in our bond leverage ratio 
exceeding the maximum allowable ratio under our indentures and still remain in compliance with the covenant.

(4)  At December 31, 2017, a portion of the net proceeds from the 51/4% Notes, together with a portion of the net proceeds 
of the Equity Offering, were used to temporarily repay approximately $807.0 million of outstanding indebtedness 
under our Revolving Credit Facility until the closing of the IODC Transaction, which occurred on January 10, 2018 
(as described in Note 6 in Notes to Consolidated Financial Statements included in this Annual Report). The bond 
leverage ratio at December 31, 2017 is calculated based on our outstanding indebtedness at this date, which reflects 
the temporary repayment of the Revolving Credit Facility.

78

 
Noncompliance with these leverage and fixed charge coverage ratios would have a material adverse effect on our 

financial condition and liquidity.

b.  2017 Issuances

In May 2017, IMI completed a private offering of 300.0 million Euros in aggregate principal amount of the Euro Notes, 
which were issued at par. The net proceeds to IMI from the Euro Notes of 296.3 million Euros (or $332.7 million, based upon 
the exchange rate between the Euro and the United States dollar on May 23, 2017 (the settlement date for the Euro Notes)), 
after deducting discounts to the initial purchasers, were used to repay outstanding borrowings under the Former Revolving 
Credit Facility.

In September 2017, IMI completed a private offering of $1,000.0 million in aggregate principal amount of the 47/8% 
Notes, which were issued at par. The net proceeds of approximately $987.5 million from the 47/8% Notes after deducting 
discounts to the initial purchasers, together with borrowings under the Revolving Credit Facility, were used to fund the 
redemption of all of the 6% Notes due 2020.

In November 2017, IM UK completed a private offering of 400.0 million British pounds sterling in aggregate principal 

amount of the GBP Notes due 2025, which were issued at par. The net proceeds to IM UK of 395.0 million British pounds 
sterling (or $522.1 million, based upon the exchange rate between the British pounds sterling and the United States dollar on 
November 13, 2017 (the settlement date for the GBP Notes due 2025)), after deducting discounts to the initial purchasers, were 
used, together with borrowings under the Revolving Credit Facility, to fund the redemption of all the GBP Notes due 2022. 

In December 2017, IMI completed a private offering of $825.0 million in aggregate principal amount of the 51/4% Notes. 

The 51/4% Notes were issued at par. The net proceeds of approximately $814.7 million from the 51/4% Notes after deducting 
discounts to the initial purchasers, together with the net proceeds from the Equity Offering and the Over-Allotment Option were 
used to finance the purchase price of the IODC Transaction, which closed on January 10, 2018, and to pay related fees and 
expenses. At December 31, 2017, the net proceeds from the 51/4% Notes, together with the net proceeds of the Equity Offering, 
were used to temporarily repay borrowings under our Revolving Credit Facility and invest in money market funds.

c.  2017 Redemptions

In August 2017, we redeemed all of the 200.0 million Canadian dollars in aggregate principal outstanding of the CAD 

Notes due 2021 (approximately $157.5 million, based upon the exchange rate between the Canadian dollar and the United 
States dollar on August 15, 2017 (the redemption date for the CAD Notes due 2021)) at 103.063% of par, plus accrued and 
unpaid interest to, but excluding the redemption date, utilizing borrowings under the Former Revolving Credit Facility. We 
recorded a charge of $6.4 million to other expense (income), net in the third quarter of 2017 related to the early extinguishment 
of this debt, representing the call premium associated with the early redemption, as well as a write-off of unamortized deferred 
financing costs.

In September 2017, we redeemed all of the $1,000.0 million in aggregate principal outstanding of the 6% Notes due 2020 

at 103.155% of par, plus accrued and unpaid interest to, but excluding, the redemption date. We recorded a charge of $41.7 
million to other expense (income), net in the third quarter of 2017 related to the early extinguishment of this debt, representing 
the call premium associated with the early redemption, as well as a write-off of unamortized deferred financing costs.

In November 2017, we redeemed all of the GBP Notes due 2022 at 104.594% of par, plus accrued and unpaid interest to, 
but excluding, the redemption date. We recorded a charge of $30.1 million to other expense (income), net in the fourth quarter 
of 2017 related to the early extinguishment of this debt, representing the call premium associated with the early redemption, as 
well as a write-off of unamortized deferred financing costs.

79

d.  Accounts Receivable Securitization Program 

In March 2015, we entered into a $250.0 million 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. Iron Mountain 
Information Management, LLC ("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. As of December 31, 2016, the maximum availability allowed and amount outstanding under the 
Accounts Receivable Securitization Program was $247.0 million. The interest rate in effect under the Accounts Receivable 
Securitization Program was 1.7% as of December 31, 2016. 

 On July 31, 2017, we amended the Accounts Receivable Securitization Program to (i) increase the maximum amount 
available from $250.0 million to $275.0 million and (ii) to extend the maturity date from March 6, 2018 to July 30, 2020, at 
which point all obligations become due. As of December 31, 2017, the maximum availability allowed and amount outstanding 
under the Accounts Receivable Securitization Program was $259.0 million. The interest rate in effect under the Accounts 
Receivable Securitization Program was 2.2% as of December 31, 2017. Commitment fees at a rate of 40 basis points are 
charged on amounts made available but not borrowed under the Accounts Receivable Securitization Program.  

e. Cash Pooling

Subsequent to the closing of the Recall Transaction, certain of our international subsidiaries began participating in a cash 

pooling arrangement (the “Cash Pool”) with Bank Mendes Gans (“BMG”) in order to help manage global liquidity 
requirements. The Cash Pool allows participating subsidiaries to receive credit for cash balances deposited by participating 
subsidiaries in BMG accounts. Under the Cash Pool, cash deposited by participating subsidiaries with BMG is 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 the debit balances based on an applicable rate as defined in the Cash Pool agreement. At 
December 31, 2016, we had a net cash position of approximately $1.7 million (consisting of a gross cash position of 
approximately $69.5 million less outstanding debit balances of approximately $67.8 million by participating subsidiaries).  

During the first quarter of 2017, we significantly expanded our utilization of the Cash Pools and reduced our utilization of 

our financing centers in Europe for purposes of meeting our global liquidity requirements. We currently utilize two separate 
cash pools with BMG, one of which we utilize to manage global liquidity requirements for our QRSs (the "QRS Cash Pool") 
and the other for our TRSs (the "TRS Cash Pool"). During the second quarter of 2017, we executed overdraft facility 
agreements for the QRS Cash Pool and TRS Cash Pool, each in an amount not to exceed $10.0 million. Each overdraft facility 
permits us to cover a temporary net debit position in the applicable pool. As of December 31, 2017, we had a net cash position 
of approximately $5.7 million in the QRS Cash Pool (which consisted of a gross cash position of approximately $383.7 million 
less outstanding debit balances of approximately $378.0 million by participating subsidiaries) and we had a zero balance in the 
TRS Cash Pool (which consisted of a gross cash position of approximately $229.6 million less outstanding debit balances of 
approximately $229.6 million by participating subsidiaries). The net cash position balances as of December 31, 2016 and 2017 
are reflected as cash and cash equivalents in the Consolidated Balance Sheets.

_______________________________________________________________________________

For more information on our Credit Agreement and our other debt agreements, see Note 4 to Notes to Consolidated 

Financial Statements included in this Annual Report.

80

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.

Equity Financing

a.  At The Market (ATM) Equity Program

In October 2017, we entered into the Distribution Agreement with the Agents pursuant to which we may 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. 
Sales of our common stock made pursuant to the Distribution Agreement may be made in negotiated transactions or 
transactions that are deemed to be “at the market” offerings as defined in Rule 415 under the Securities Act, including sales 
made directly on the NYSE, or sales made to or through a market maker other than on an exchange, or as otherwise agreed 
between the applicable Agent and us. We intend to use the net proceeds from sales of our common stock pursuant to the At The 
Market (ATM) Equity Program for general corporate purposes, including financing the expansion of our data center business 
and adjacent businesses through acquisitions, and repaying amounts outstanding from time to time under the Revolving Credit 
Facility.

During the quarter ended December 31, 2017 under the At The Market (ATM) Equity Program, we sold an aggregate of 

1,481,053 shares of common stock for gross proceeds of $60.0 million, generating net proceeds of $59.1 million, after 
deducting commissions of $0.9 million. As of December 31, 2017, the remaining aggregate sale price of shares of our common 
stock available for distribution under the At The Market (ATM) Equity Program was approximately $440.0 million.

b. Equity Offering

On December 12, 2017, we entered into the Underwriting Agreement with the Underwriters related to the Equity 
Offering. The offering price to the public for the Equity Offering was $37.00 per share, and we agreed to pay the Underwriters 
an underwriting commission of $1.38195 per share. The net proceeds to us from the Equity Offering, after deducting 
underwriters' commissions, was $516.5 million.

Pursuant to the Underwriting Agreement, we granted the Underwriters the Over-Allotment Option. On January 10, 2018, 

the Underwriters exercised the Over-Allotment Option in its entirety. The net proceeds to us from the exercise of the Over-
Allotment Option, after deducting underwriters' commissions and the per share value of the dividend that we declared on our 
common stock, with the record date on December 15, 2017 and which was paid on January 2, 2018, was approximately $76.2 
million. The net proceeds of the Equity Offering and the Over-Allotment Option, together with the net proceeds from the 
issuance of the 5¼% Notes, were used to finance the purchase price of the IODC Transaction, which closed on January 10, 
2018, and to pay related fees and expenses. At December 31, 2017, the net proceeds of the Equity Offering, together with the 
net proceeds from the 51/4% Notes, were used to temporarily repay borrowings under our Revolving Credit Facility and invest 
in money market funds.

Acquisitions

a. Acquisition of Recall

On May 2, 2016 (Sydney, Australia time), we completed the Recall Transaction. At the closing of the Recall Transaction, 
we paid approximately $331.8 million in cash and issued approximately 50.2 million shares of our common stock which, based 
on the closing price of our common stock as of April 29, 2016 (the last day of trading on the NYSE prior to the closing of the 
Recall Transaction) of $36.53 per share, resulted in a total purchase price to Recall shareholders of approximately $2,166.9 
million.    

We currently estimate total acquisition and integration expenditures associated with the Recall Transaction to be 

approximately $380.0 million, the majority of which is expected to be incurred by the end of 2018. This amount consists of (i) 
Recall Costs and (ii) capital expenditures to integrate Recall with our existing operations.

81

The following table presents the operating and capital expenditures associated with the Recall Transaction incurred for the 

years ended December 31, 2015, 2016 and 2017 and the cumulative amount incurred through December 31, 2017 (in

b.  Noteworthy 2017 Acquisitions

In November 2016, we entered into a binding agreement to acquire the storage and information management assets and 

operations of Santa Fe Group A/S ("Santa Fe") in ten regions within Europe and Asia in order to expand our presence in 
southeast Asia and western Europe. In December 2016, we acquired the storage and information management assets and 
operations of Santa Fe in Hong Kong, Malaysia, Singapore, Spain and Taiwan (the “2016 Santa Fe Transaction”) for 
approximately 15.2 million Euros (approximately $16.0 million, based upon the exchange rate between the United States dollar 
and the Euro as of December 30, 2016, the closing date of the 2016 Santa Fe Transaction). Of the total purchase price, 13.5 
million Euros (or approximately $14.2 million, based upon the exchange rate between the United States dollar and the Euro on 
the closing date of the 2016 Santa Fe Transaction) was paid during the year ended December 31, 2016, and the remaining 
balance is due on the 18-month anniversary of the closing of the 2016 Santa Fe Transaction. 

During the first half of 2017, we acquired, in two separate transactions, (i) the storage and information management assets 

and operations of Santa Fe in Macau and South Korea, and (ii) the storage and information management assets and operations 
of Santa Fe in India, Indonesia and the Philippines (collectively, the “2017 Santa Fe Transaction”) for approximately 11.7 
million Euros (or approximately $13.0 million, based upon the exchange rate between the United States dollar and the Euro on 
the closing dates of the respective transactions).

In November 2017, in order to expand our existing operations in China, we entered into an agreement to acquire (i) the 

storage and information management assets and operations of Santa Fe in China (the “Santa Fe China Transaction”) for 
approximately 14.0 million Euros and (ii) certain real estate property located in Beijing, China owned by Santa Fe (the “Beijing 
Property”) for approximately 9.0 million Euros, representing a total purchase price of approximately 23.0 million Euros, 
subject to customary purchase price adjustments. On December 29, 2017, we closed on the Santa Fe China Transaction. The 
purchase price for the Santa Fe China Transaction was not paid until January 2018 and, therefore, we have accrued for the 
purchase price of the Santa Fe China Transaction (which was approximately $16.8 million, based upon the exchange rate 
between the Euro and the United States dollar on the closing date of the Santa Fe China Transaction) in our consolidated 
balance sheet as of December 31, 2017 (the “Accrued Purchase Price”). The Accrued Purchase Price is presented as a 
component of current portion of long-term debt in our consolidated balance sheet as of December 31, 2017. We expect to close 
the acquisition of the Beijing Property during the first half of 2018. The completion of the acquisition of the Beijing Property is 
subject to closing conditions; accordingly, we can provide no assurances that we will be able to complete the acquisition of the 
Beijing Property, that it will not be delayed or that the terms will remain the same. 

In June 2017, in order to expand our presence in Peru, we acquired the storage and information management assets and 

operations of Ransa Comercial, S.A. and Depositos, S.A, two records and storage and information management companies 
with operations in Peru, for approximately $14.7 million.

In July 2017, in order to expand our European operations, we acquired Fileminders Ltd., a storage and records 

management company with operations in Cyprus for approximately 24.9 million Euros (or approximately $28.5 million, based 
upon the exchange rate between the United States dollar and the Euro on the closing date of the acquisition).

82

In September 2017, in order to expand our data center operations in the United States, we acquired Mag Datacenters LLC, 
which operated Fortrust, a private data center business with operations in Denver, Colorado (the “Fortrust Transaction”). At the 
closing of the Fortrust Transaction, we paid approximately $54.5 million in cash (the "Fortrust Cash Consideration") and issued 
2.2 million shares of our common stock (the "Fortrust Stock Consideration"). The shares of our common stock issued to the 
former owners of Fortrust in connection with the Fortrust Transaction contain certain restrictions that impact the marketability 
of such shares for a period of six months following the closing date of the Fortrust Transaction (the “Lack of Marketability 
Restriction”). The 2.2 million shares issued as part of the Fortrust Stock Consideration were valued at approximately $37.84 
per share, which represents the closing price of our common stock as of August 31, 2017 (the last day of trading on the NYSE 
prior to the closing of the Fortrust Transaction), discounted for the Lack of Marketability Restriction, resulting in a total 
purchase price (including the Fortrust Cash Consideration and the Fortrust Stock Consideration) of approximately $137.5 
million.   

In September 2017, in order to expand our existing entertainment storage and services operations in the United States and 

to expand our entertainment storage and services operations into Canada, France, Hong Kong, the Netherlands and the United 
Kingdom, we acquired Bonded Services of America, Inc. and Bonded Services Acquisition, Ltd., providers of media asset 
storage and management services for global entertainment and media companies (the “Bonded Transaction”), for 
approximately 62.0 million British pounds sterling (or approximately $83.0 million, based upon the exchange rate between the 
British pound sterling and the United States dollar on September 29, 2017, the closing date of the Bonded Transaction).

In October 2017, in order to expand our presence in India, we acquired OEC Records Management, a storage and 

information management company with operations in India for approximately $19.3 million.

In addition to the transactions noted above, during 2017, in order to enhance our existing operations in the United States, 

Greece and South Africa and to expand our operations into the United Arab Emirates, we completed the acquisition of five 
storage and records management companies, one storage and data management company and one art storage company for total 
consideration of approximately $22.7 million. The individual purchase prices of these acquisitions were each less than $5.0 
million.

c. Acquisitions Closed or Expected to Close in 2018

On January 10, 2018, we completed the IODC Transaction. At the closing of the IODC Transaction, we paid 

approximately $1,340.0 million of total consideration, including the Initial IODC Consideration and the IODC Contingent 
Consideration. The proceeds for the IODC Transaction were provided by the Equity Offering, the Over-Allotment Option and 
the issuance of the 5¼% Notes. At December 31, 2017, the net proceeds from the 51/4% Notes and the Equity Offering were 
used to temporarily repay borrowings under our Revolving Credit Facility and invest in money market funds. At the closing of 
the IODC Transaction, we utilized the cash in the money market funds and additional borrowings under our Revolving Credit 
Facility to finance the purchase price of the IODC Transaction. 

In October 2017, we entered into agreements to acquire two data centers located in London and Singapore from Credit 
Suisse International and Credit Suisse AG (together, "Credit Suisse") for an aggregate cash purchase price of approximately 
$100.0 million (the “Credit Suisse Transaction”). As part of the Credit Suisse Transaction, we will take ownership of both data 
center facilities, with Credit Suisse entering into a long-term lease with us to maintain existing data center operations. The 
completion of the Credit Suisse Transaction is subject to closing conditions; accordingly, we can provide no assurance that we 
will be able to complete the Credit Suisse Transaction, that the Credit Suisse Transaction will not be delayed or that the terms 
will remain the same. We expect to close the Credit Suisse Transaction during the first half of 2018.

(1)  Amounts include variable rate interest payments, which are calculated utilizing the applicable interest rates as of 
December 31, 2017; see Note 4 to Notes to Consolidated Financial Statements included in this Annual Report. 
Amounts also include interest on capital leases.

(2)  These amounts are net of sublease income of $36.4 million in total (including $7.5 million, $10.9 million, $8.7 million 

and $9.3 million, in less than 1 year, 1-3 years, 3-5 years and more than 5 years, respectively).

(3)  The table above excludes $38.5 million in uncertain tax positions as we are unable to make reliable estimates of the 

period of cash settlement, if any, with the respective taxing authorities.

(4)  The table above excludes $91.4 million of redeemable noncontrolling interests, which represents the estimated 

redemption value of the redeemable noncontrolling interests in our consolidated subsidiaries in Chile, India and South 
Africa. This table also excludes purchase commitments associated with acquisitions closed or expected to close in 
2018.

We expect to meet our cash flow requirements for the next twelve months from cash generated from operations, cash on 
hand, borrowings under the Credit Agreement and other financings (including the issuance of equity under our At The Market 
(ATM) Equity Program). We expect to meet our long-term cash flow requirements using the same means described above. We 
are currently operating above our long-term targeted leverage ratio, primarily as a result of costs incurred to fund the REIT 
conversion, the Recall Transaction and, more recently, the IODC Transaction. We expect our leverage ratio to reduce over time 
through effective capital allocation strategies and business growth.

Off-Balance Sheet Arrangements

We have no off-balance sheet arrangements as defined in Regulation S-K Item 303(a)(4)(ii).

Net Operating Losses

We have federal net operating loss carryforwards, which expire from 2023 through 2036, of $66.3 million at December 

31, 2017 to reduce future federal taxable income, of which $1.7 million of federal tax benefit is expected to be realized. We can 
carry forward these net operating losses to the extent we do not utilize them in any given available year. We have state net 
operating loss carryforwards, which expire from 2018 through 2036, of which an insignificant state tax benefit is expected to be 
realized. We have assets for foreign net operating losses of $103.6 million, with various expiration dates (and in some cases no 
expiration date), subject to a valuation allowance of approximately 59%.

Inflation

Certain of our expenses, such as wages and benefits, insurance, occupancy costs and equipment repair and replacement, 

are subject to normal inflationary pressures. Although to date we have been able to offset inflationary cost increases with 
increased operating efficiencies, the negotiation of favorable long-term real estate leases and an ability to increase prices in our 
customer contracts (many of which contain provisions for inflationary price escalators), we can give no assurance that we will 
be able to offset any future inflationary cost increases through similar efficiencies, leases or increased storage rental or service 
charges.

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, 2017 relate to cash and cash equivalents held on deposit with seven global banks and 12 "Triple A" rated money 
market funds, all of which we consider to be large, highly-rated investment-grade institutions. 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 $50.0 million or in any one financial institution to a maximum of $75.0 million. As of December 31, 2017, our 
cash and cash equivalents balance was $925.7 million, which included money market funds amounting to $585.0 million and 
time deposits amounting to $24.5 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. We target approximately 75% of our debt portfolio to be fixed with respect to interest 
rates. Occasionally, we may use interest rate swaps as a tool to maintain our targeted level of fixed rate debt. See Notes 3 and 4 
to Notes to Consolidated Financial Statements included in this Annual Report.

As of December 31, 2017, we had $1,354.5 million of variable rate debt outstanding with a weighted average variable 

interest rate of approximately 4.4%, and $5,775.0 million of fixed rate debt outstanding. As of December 31, 2017, 
approximately 81% 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, 2017 would have been reduced by approximately 
$15.0 million. See Note 4 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, 2017.

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 treasury centers in Europe, 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.

85

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, 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. Similarly, Canada Company has financed a portion of its capital 
needs through direct borrowings in Canadian dollars under the Credit Agreement and through the issuance of the CAD Notes 
due 2023. This creates a tax efficient natural currency hedge. During the year ended December 31, 2017, we designated a 
portion of the Euro Notes and our Euro denominated borrowings by IMI under the Revolving Credit Facility as a hedge of net 
investment of certain of our Euro denominated subsidiaries. As a result, we recorded $15.0 million ($15.0 million, net of tax) of 
foreign exchange losses related to the "marking-to-market" of such debt to currency translation adjustments which is a 
component of accumulated other comprehensive items, net included in stockholders' equity for the year ended December 31, 
2017. As of December 31, 2017, cumulative net gains of $3.2 million, net of tax are recorded in accumulated other 
comprehensive items, net associated with this net investment hedge.

Historically, we have entered into forward contracts to hedge our exposures in Euros, British pounds sterling and 

Australian dollars. As of December 31, 2017, we had outstanding forward contracts to (i) purchase $138.8 million United 
States dollars and sell 176.0 million Canadian dollars, (ii) purchase 135.0 million Euros and sell $160.8 million United States 
dollars and (iii) purchase $114.4 million United States dollars and sell 96.2 million Euros to hedge our foreign exchange 
exposures. 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 expense (income), 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. We have not designated any of the forward contracts we have 
entered as hedges. During the year ended December 31, 2017, cash receipts included in cash from operating activities from 
continuing operations related to settlements associated with foreign currency forward contracts were $9.1 million. We recorded 
net gains in connection with forward contracts of $8.3 million, including an unrealized foreign exchange loss of $0.8 million 
related to the forward contracts in other expense (income), net as of December 31, 2017 in the Consolidated Financial 
Statements included in this Annual Report. As of December 31, 2017, except as noted above, our currency exposures to 
intercompany balances are not hedged.

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 2017 functional 
currencies, relative to the United States dollar, would result in a reduction in our equity of approximately $241.5 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, 2017 (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, 2017.

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
Boston, Massachusetts

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, 2017, 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, 2017, 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, 2017, of the Company and 
our report dated February 16, 2018, 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.

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, 2017 and 2016, 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, 2017, 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, 2017 and 2016, and 
the results of its operations and its cash flows for each of the three years in the period ended December 31, 2017, in conformity 
with 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, 2017, 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 16, 2018, 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.

IRON MOUNTAIN INCORPORATED

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

DECEMBER 31, 2017
(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 store records, primarily physical records and data backup media, 
provide colocation and wholesale data center spaces and provide information management and data center solutions that help 
organizations in various locations throughout North America, Europe, Latin America, Asia and Africa protect their information, 
lower storage rental 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 
currently serve customers across an array of market verticals - commercial, legal, financial, healthcare, insurance, life sciences, 
energy, business services, entertainment and government organizations.

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. 

On May 2, 2016 (Sydney, Australia time), we completed the acquisition of Recall Holdings Limited ("Recall") pursuant 

to the Scheme Implementation Deed, as amended, with Recall (the "Recall Transaction"). See Note 6. 

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.  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.

At December 31, 2017, we had approximately $22,167 of restricted cash held by certain financial institutions related to 

bank guarantees. We adopted Accounting Standards Update ("ASU") No. 2016-18, Statement of Cash Flows (Topic 230): 
Restricted Cash ("ASU 2016-18"), which is discussed in greater detail in Note 2.w., during the fourth quarter of 2017. Our 
consolidated statement of cash flows for the years ended December 31, 2015, 2016 and 2017 reflect our adoption of ASU 
2016-18.

d.  Foreign Currency

Local currencies are the functional currencies for our operations outside the United States, with the exception of certain 
foreign holding companies and our financing centers in Europe, 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. Resulting translation adjustments 
are reflected in the accumulated other comprehensive, net components of Iron Mountain Incorporated Stockholders' Equity. The 
gain or loss on foreign currency transactions, calculated as the difference between the historical exchange rate and the exchange 
rate at the applicable measurement date, including those related to (i) our previously outstanding 63/4% Euro Senior 
Subordinated Notes due 2018 (the "63/4% Notes"), (ii) our 3% Euro Senior Notes due 2025 (the "Euro Notes"), (iii) borrowings 
in certain foreign currencies under our Revolving Credit Facility and our Former Revolving Credit Facility (each as defined in 
Note 4) and (iv) certain foreign currency denominated intercompany obligations of our foreign subsidiaries to us and between 
our foreign subsidiaries, which are not considered permanently invested, are included in Other expense (income), net, in the 
accompanying Consolidated Statements of Operations. 

The total loss on foreign currency transactions for the years ended December 31, 2015, 2016 and 2017 is as follows:

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 target approximately 75% of our debt portfolio to be fixed 
with respect to interest rates. Occasionally, we may use interest rate swaps as a tool to maintain our targeted level of fixed rate 
debt. In addition, we may 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. Sometimes we enter into currency 
swaps to temporarily hedge an overseas investment, such as a major acquisition, while we arrange permanent financing or to 
hedge our exposure due to foreign currency exchange movements related to our intercompany accounts with and between our 
foreign subsidiaries. We had no forward contracts outstanding as of December 31, 2016. As of December 31, 2017, none of our 
derivative instruments contained credit-risk related contingent features. See Note 3.

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. Major improvements to leased buildings are capitalized 
as leasehold improvements and depreciated.

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. 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. During the years ended December 31, 2015, 2016 and 2017, we capitalized $26,201, $16,438 and 
$25,166 of costs, respectively, associated with the development of internal use computer software projects. 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 year ended December 31, 2016, we wrote off $1,833 of previously deferred software costs within the North 

American Records and Information Management Business segment associated with internal use software development projects 
that were discontinued after implementation, which resulted in a loss on disposal/write-down of property, plant and equipment 
(excluding real estate), net in the accompanying Consolidated Statements of Operations. We did not record any write-offs of 
deferred software costs during the years ended December 31, 2015 and 2017.

2. Summary of Significant Accounting Policies (Continued)

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. When the liability is initially recorded, the entity capitalizes the cost by increasing the 
carrying amount of the related long-lived asset, which is then depreciated over the useful life of the related asset. The liability is 
increased over time through accretion expense (included in depreciation expense) such that the liability will equate to the future 
cost to retire the long-lived asset at the expected retirement date. Upon settlement of the liability, an entity either settles the 
obligation for its recorded amount or realizes a gain or loss upon settlement. 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 obligation 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.

A reconciliation of liabilities for asset retirement obligations (included in other long-term liabilities) is as follows:

Asset Retirement Obligations, beginning of the year

Liabilities Assumed

Liabilities Incurred

Liabilities Settled

Accretion Expense

Foreign Currency Translation Adjustments

g.  Long-Lived Assets

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 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.

Consolidated loss (gain) on disposal/write-down of property, plant and equipment (excluding real estate), net was $3,000 
for the year ended December 31, 2015 and consisted primarily of losses associated with the write-off of certain property in our 
Western European Business and North American Records and Information Management Business segments. Consolidated loss 
(gain) on disposal/write-down of property, plant and equipment (excluding real estate), net was $1,412 for the year ended 
December 31, 2016 and consisted primarily of losses associated with the write-off of certain software assets associated with our 
North American Records and Information Management Business segment. Consolidated loss (gain) on disposal/write-down of 
property, plant and equipment (excluding real estate), net was $799 for the year ended December 31, 2017 and consisted 
primarily of losses associated with the write-off of certain property in our Other International Business segment, partially offset 
by gains on the retirement of leased vehicles accounted for as capital lease assets primarily associated with our North American 
Records and Information Management Business segment.

Gain on sale of real estate for the year ended December 31, 2015 was $850, net of tax of $209, and consisted primarily of 
the sale of a building in the United Kingdom. Gain on sale of real estate for the year ended December 31, 2016 was $2,180, net 
of tax of $130, and consisted primarily of the sale of land and buildings in the United States and Canada. Gain on sale of real 
estate for the year ended December 31, 2017 was $1,565 and consisted primarily of the sale of land and building in the United 
States for net proceeds of approximately $12,700.

h.  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, 2015 and 2016 and concluded that goodwill was not impaired as of such dates. We have 
performed our annual goodwill impairment review as of October 1, 2017 and as a result of that review, we determined that the 
fair value of the Consumer Storage reporting unit (formerly referred to as the Adjacent Businesses - Consumer Storage 
reporting unit) was less than its carrying value and, therefore, we recorded a $3,011 impairment charge on the goodwill 
associated with this reporting unit during the fourth quarter of 2017, which represents a write-off of all goodwill associated with 
this reporting unit. 

The following is a discussion regarding (i) the reporting units at which level we tested goodwill for impairment as of 
October 1, 2016, (ii) our reporting units as of December 31, 2016 (including the amount of goodwill associated with each 
reporting unit), (iii) the reporting units at which level we tested goodwill for impairment as of October 1, 2017, and (iv) our 
reporting units as of December 31, 2017 (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.

Goodwill Impairment Analysis - 2017

a. Changes to Composition of Reporting Units between December 31, 2016 and October 1, 2017

Prior to the Russia and Ukraine Divestment (as defined and more fully disclosed in Note 14), our businesses in Russia and 

Ukraine were a component of our Northern and Eastern Europe reporting unit. As disclosed in Note 14, on May 30, 2017, Iron 
Mountain EES Holdings Ltd. ("IM EES"), a consolidated subsidiary of IMI, sold its records and information management 
operations in Russia and Ukraine. As a result of the Russia and Ukraine Divestment, $3,515 of goodwill associated with our 
Northern and Eastern Europe reporting unit was allocated, on a relative fair value basis, to the Russia and Ukraine Divestment 
and included in the carrying value of the divested businesses. 

During the second quarter of 2017, as a result of changes in the management of our businesses included in our Other 
International Business segment, we reassessed the composition of our reporting units. As a result of this reassessment, we 
determined that our businesses in our former Africa and India reporting unit, which included our businesses in South Africa and 
India, as well as our business in the United Arab Emirates which was acquired in the first quarter of 2017, were now being 
managed in conjunction with our businesses included in our Northern and Eastern Europe reporting unit. This newly formed 
reporting unit, which consists of (i) the businesses included in our former Northern and Eastern Europe reporting unit and (ii) 
our businesses in the United Arab Emirates, South Africa and India is referred to as the Northern/Eastern Europe and Middle 
East, Africa and India, or NEE and MEAI, reporting unit. 

During the second quarter of 2017, we reassessed the composition of our reporting units included in our North American 

Records and Information Management Business segment. As a result of this reassessment, we determined that the discrete 
financial information and operating results of our North American Secure Shredding business are no longer being regularly 
reviewed by the segment manager of our North American Records and Information Management Business segment. Therefore, 
we have concluded that our secure shredding operations in North America no longer constitute a separate reporting unit and that 
our North American Records and Information Management Business segment consists of one reporting unit, which is referred 
to as the North American Records and Information Management reporting unit. 

b. Reporting Units as of October 1, 2017

As a result of the changes described above, our reporting units at which level we performed our goodwill impairment 
analysis as of October 1, 2017 were as follows: (1) North American Records and Information Management; (2) North American 
Data Management; (3) Global Data Center (which had no goodwill at October 1, 2017 and was formerly referred to as the 
Adjacent Businesses - Data Centers reporting unit); (4) Consumer Storage; (5) Fine Arts (formerly referred to as the Adjacent 
Businesses - Fine Arts reporting unit); (6) Western Europe; (7) NEE and MEAI; (8) Latin America; (9) Australia and New 
Zealand; and (10) Asia (formerly referred to as the Southeast Asia reporting unit). As discussed above, we recorded a $3,011 
impairment charge on the goodwill associated with our Consumer Storage reporting unit during the fourth quarter of 2017, 
which represents a write-off of all goodwill associated with this reporting unit. We concluded that the goodwill associated with 
each of our other reporting units was not impaired as of such date.

c. Changes to Composition of Reporting Units as of December 31, 2017

During the fourth quarter of 2017, as a result of changes in the management of our entertainment storage and services 
business, we reassessed the composition of our reportable operating segments (see Note 9 for a description of our reportable 
operating segments) as well as our reporting units. As a result of this reassessment, we determined that our entertainment 
storage and services businesses in the United States and Canada, which were previously included within our North American 
Data Management reporting unit, were being managed in conjunction with our entertainment storage and services businesses in 
France, Hong Kong, the Netherlands and the United Kingdom (the majority of which were acquired in the third quarter of 2017 
as part of the Bonded Transaction (as defined and more fully disclosed in Note 6)). This newly formed reporting unit is referred 
to as the Entertainment Services reporting unit. We have reassigned the related goodwill associated to the reporting units 
impacted by this change on a relative fair value basis.

2. Summary of Significant Accounting Policies (Continued)

As of December 31, 2017, no factors were identified that would alter our October 1, 2017 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.

Goodwill by Reporting Unit as of December 31, 2017

The carrying value of goodwill, net for each of our reporting units described above as of December 31, 2017 is as follows:

Reporting unit valuations have generally been determined using a combined approach based on the present value of future 

cash flows and market multiples. The income approach incorporates many assumptions including future growth rates and 
operating margins, discount rate factors, expected capital expenditures and income tax cash flows. Changes in economic and 
operating conditions impacting these assumptions 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.

2. Summary of Significant Accounting Policies (Continued)

(1)  Goodwill allocated to Iron Mountain Divestments includes $40,089 and $3,332 of goodwill allocated to the Australia 

Divestment Business and the Iron Mountain Canadian Divestments (each as defined in Note 6), respectively. 

(2)  Total fair value and other adjustments primarily include net adjustments of $(1,425) related to property, plant and 

equipment, customer relationship intangible assets (which represent adjustments within the applicable measurement 
period to provisional amounts recognized in purchase accounting) and other liabilities, and $182 of cash received 
related to certain acquisitions completed in 2015. 

(3)  Goodwill allocated to the Russia and Ukraine Divestment.

(4)  Total fair value and other adjustments primarily include net adjustments of $6,628 primarily related to property, plant 
and equipment, and customer relationship intangible assets (which represent adjustments within the applicable 
measurement period to provisional amounts recognized in purchase accounting). 

i.  Customer Relationship Intangible Assets, Customer Inducements and Other Finite-Lived Intangible Assets

Customer relationship intangible assets, which are acquired through either business combinations or acquisitions of 
customer relationships, are amortized over periods ranging from ten to 30 years (weighted average of 18 years at December 31, 
2017). The value of customer relationship intangible assets is calculated based upon estimates of their fair value utilizing an 
income approach based on the present value of expected future cash flows.

Costs related to the acquisition of large volume accounts are capitalized. Free intake costs to transport boxes to one of our 
facilities, which include labor and transportation costs ("Move Costs"), are amortized over periods ranging from ten to 30 years 
(weighted average of 26 years as of December 31, 2017), and are included in depreciation and amortization in the 
accompanying Consolidated Statements of Operations. Payments that are made to a customer's current records management 
vendor in order to terminate the customer's existing contract with that vendor, or direct payments to a customer ("Permanent 
Withdrawal Fees"), are amortized over periods ranging from five to 15 years (weighted average of seven years as of 
December 31, 2017), and are included in storage and service revenue in the accompanying Consolidated Statements of 
Operations. Move Costs and Permanent Withdrawal Fees are collectively referred to as "Customer Inducements". If the 
customer terminates its relationship with us, the unamortized carrying value of the Customer Inducement intangible asset is 
charged to expense or 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. 

Other finite-lived intangible assets, including trade names, noncompetition agreements and trademarks, are capitalized and 
amortized over a weighted average of four years as of December 31, 2017, and are included in depreciation and amortization in 
the accompanying Consolidated Statements of Operations.

j.  Deferred Financing Costs

Deferred financing costs are amortized over the life of the related debt using the effective interest rate method. If debt is 
retired early, the related unamortized deferred financing costs are written-off in the period the debt is retired to other expense 
(income), net. As of December 31, 2016 and 2017, the gross carrying amount of deferred financing costs was $92,982 and 
$113,678, respectively, and accumulated amortization of those costs was $25,047 and $27,438, respectively. Unamortized 
deferred financing costs are included as a component of long-term debt in our Consolidated Balance Sheets.

l.  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) and technology escrow services that protect and manage source code. Service revenues include 
charges for related service activities, which include: (1) the handling of records, including the addition of new records, 
temporary removal of records from storage, refiling of removed records and the destruction of records; (2) courier operations, 
consisting primarily of the pickup and delivery of records upon customer request; (3) secure shredding of sensitive documents 
and the related sale of recycled paper, the price of which can fluctuate from period to period; (4) other services, including the 
scanning, imaging and document conversion services of active and inactive records ("Information Governance and Digital 
Solutions") which relate to physical and digital records, and project revenues; (5) customer termination and permanent removal 
fees; (6) data restoration projects; (7) special project work; (8) the storage, assembly, reporting and delivery of customer 
marketing literature, or fulfillment services; (9) consulting services; (10) cloud-related data protection, preservation, restoration 
and recovery; and (11) other technology services and product sales (including specially designed storage containers and related 
supplies).

We recognize revenue when the following criteria are met: (1) persuasive evidence of an arrangement exists; (2) services 
have been rendered; (3) the sales price is fixed or determinable; and (4) collectability of the resulting receivable is reasonably 
assured. Storage rental and service revenues are recognized in the month the respective storage rental or service is provided, 
and customers are generally billed on a monthly basis on contractually agreed-upon terms. Amounts related to future storage 
rental or prepaid service contracts for customers where storage rental fees or services are billed in advance are accounted for as 
deferred revenue and recognized ratably over the period the applicable storage rental or service is provided or performed. 
Revenues from the sales of products, which are included as a component of service revenues, are recognized when products are 
shipped and title has passed to the customer. Revenues from the sales of products, which represented less than 2% of 
consolidated revenue for the year ended December 31, 2017, have historically not been significant.

In May 2014, the Financial Accounting Standards Board ("FASB") issued ASU No. 2014-09, Revenue from Contracts 

with Customers (Topic 606) ("ASU 2014-09"). ASU 2014-09 provides guidance for management to reassess revenue 
recognition as it relates to: (1) transfer of control, (2) variable consideration, (3) allocation of transaction price based on relative 
standalone selling price, (4) licenses, (5) time value of money, and (6) contract costs. In August 2015, the FASB issued ASU 
No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date ("ASU 2015-14"). ASU 
2015-14 deferred the effective date of ASU 2014-09 for one year, making it effective for us on January 1, 2018, with early 
adoption permitted as of January 1, 2017. We will adopt ASU 2014-09 as of January 1, 2018. See Note 2.w. for additional 
information on ASU 2014-09.

m.  Rent Normalization

We have entered into various leases for buildings that expire over various terms. Certain leases have fixed escalation 
clauses (excluding those tied to the consumer price index or other inflation-based indices) or other features (including return to 
original condition, primarily in the United Kingdom) which require normalization of the rental expense over the life of the 
lease, resulting in deferred rent being reflected as a liability in the accompanying Consolidated Balance Sheets. In addition, we 
have assumed various above and below market leases in connection with certain of our acquisitions. The difference between the 
present value of these lease obligations and the market rate at the date of the acquisition was recorded as either a deferred rent 
liability (which is a component of Other Long-Term Liabilities) or deferred rent asset (which is a component of Other within 
Other Assets, net) in our Consolidated Balance Sheets and is being amortized to rent expense.

n.  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").

Stock-based compensation expense for Employee Stock-Based Awards included in the accompanying Consolidated 
Statements of Operations for the years ended December 31, 2015, 2016 and 2017 was $27,585 ($19,679 after tax or $0.09 per 
basic and diluted share), $28,976 ($22,364 after tax or $0.09 per basic and diluted share) and $30,019 ($26,512 after tax or

Stock Options

Under our various stock option plans, 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 options we issue become exercisable ratably over a period of either (i) three years from the date of 
grant and have a contractual life of ten years from the date of grant, unless the holder's employment is terminated sooner, (ii) 
five years from the date of grant and have a contractual life of ten years from the date of grant, unless the holder's employment 
is terminated sooner, or (iii) ten years from the date of grant and have a contractual life of 12 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.

A summary of our stock options outstanding as of December 31, 2017 by vesting terms is as follows:

Our equity compensation plans generally provide that any unvested options and other awards granted thereunder shall 

vest immediately if an employee is terminated, or terminates their own employment for good reason (as defined in each plan), 
in connection with a vesting change in control (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"). Under the 
2014 Plan, the total amount of shares of common stock reserved and available for issuance pursuant to awards granted under 
the 2014 Plan is 12,750,000. The 2014 Plan permits us to continue to grant awards through May 24, 2027.

A total of 48,253,839 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, 2017 was 8,059,090.

The weighted average fair value of stock options granted in 2015, 2016 and 2017 was $4.84, $2.56 and $4.28 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 year ended December 31:

Expected volatility is calculated utilizing daily historical volatility over a period that equates to the expected life of the 

option. The risk-free interest rate was 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. 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. The expected life of the stock options granted is estimated using the historical exercise behavior of employees.

Under our various equity compensation plans, we may also grant RSUs. Our RSUs generally have a vesting period of 

three years from the date of grant. However, RSUs granted to our non-employee directors in 2015 and thereafter 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 purchase 
price (which is typically zero).

Performance Units

Under our various equity compensation plans, we may also make awards of PUs. For the majority of outstanding PUs, the 

number of PUs earned is determined based on our performance against predefined targets of revenue and return on invested 
capital ("ROIC"). The number of PUs earned may range from 0% to 200% of the initial award. The number of PUs earned is 
determined based on our actual performance as compared to the targets at the end of a three-year performance period. Certain 
PUs that we grant will be earned based on a market condition associated with the total return on our common stock in relation 
to a subset of the Standard & Poor's 500 Index rather than the revenue and ROIC targets noted above. The number of PUs 
earned based on this market condition may range from 0% to 200% of the initial award. 

All of our PUs will be settled in shares of our common stock and are subject to cliff vesting three years from the date of 
the original PU grant. PUs awarded to employees who terminate their employment during the three-year performance period 
and on or after attaining age 55 and completing 10 years of qualifying service are eligible for pro-rated vesting, subject to the 
actual achievement against the predefined targets or a market condition as discussed above, based on the number of full years of 
service completed following the grant date (but delivery of the shares remains deferred). 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, 2015, 2016 and 2017, we issued 159,334, 231,672 and 229,692 PUs, respectively. 

The majority of our PUs are earned based on our performance against revenue and ROIC targets during their applicable 
performance period, therefore, we forecast the likelihood of achieving the predefined revenue and ROIC targets 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 date of the grant date) over the vesting 
period for each of the awards. The fair value of PUs based on our performance against revenue and ROIC 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. As of December 31, 2017, we expected 50%, 100% and 100% 
achievement of the predefined revenue and ROIC targets associated with the awards of PUs made in 2015, 2016 and 2017, 
respectively.

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 a way for our eligible employees to become stockholders on 
favorable terms. 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. For the years ended December 31, 2015, 
2016 and 2017, there were 122,209, 110,835 and 102,826 shares, respectively, purchased under the ESPP. As of December 31, 
2017, we have 624,768 shares available under the ESPP.

_______________________________________________________________________________

As of December 31, 2017, unrecognized compensation cost related to the unvested portion of our Employee Stock-Based 

Awards was $37,849 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.

o.  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 (benefit) provision for income taxes in the accompanying Consolidated Statements of 
Operations.

p.  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, 2015, 2016 and 2017 is as 

follows:

Income (loss) from continuing operations
Less: Net income (loss) attributable to noncontrolling interests

q.  Allowance for Doubtful Accounts and Credit Memo Reserves

We maintain an allowance for doubtful accounts and credit memos 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 consider 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 may be required. We charge-off uncollectible balances as circumstances 
warrant, generally, no later than one year past due.

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

r.  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, 2016 and 2017, respectively, related to cash and cash equivalents. At December 31, 2016, we had time deposits 
with six global banks. At December 31, 2017, we had money market funds with 12 "Triple A" rated money market funds and 
time deposits with seven global banks. 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 $50,000 or in any one financial institution 
to a maximum of $75,000. As of December 31, 2016 and 2017, our cash and cash equivalents balance was $236,484 and 
$925,699, respectively. At December 31, 2016, our cash and cash equivalents included time deposits of $22,240. At December 
31, 2017, our cash and cash equivalents included money market funds of $585,000 and time deposits of $24,482.

s.  Fair Value Measurements

Entities are permitted under GAAP to elect to measure many financial instruments and certain other items at either fair 

value or cost. We have elected the cost measurement 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.

(In thousands, except share and per share data)

2. Summary of Significant Accounting Policies (Continued)

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, 2016 and 2017, 

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 relate to short-term (six months or less) foreign currency contracts that we have 

entered into to hedge certain of our foreign exchange intercompany exposures, as more fully disclosed at Note 3. We 
calculate the value of such forward contracts by adjusting the spot rate utilized at the balance sheet date for translation 
purposes by an estimate of the forward points observed in active markets. 

Disclosures are required in the financial statements for items measured at fair value on a non-recurring basis. We did not 
have any material items that are measured at fair value on a non-recurring basis for the years ended December 31, 2015, 2016 
and 2017, with the exception of: (i) the reporting units as presented in our goodwill impairment analysis (as disclosed in Note 
2.h.); (ii) the assets and liabilities acquired through acquisitions (as disclosed in Note 6); (iii) the Access Contingent 
Consideration (as defined and disclosed in Note 6); (iv) the redemption value of certain redeemable noncontrolling interests (as 
disclosed in Note 2.x.); and (v) our investment in OSG  (as defined and disclosed in Note 14), all of which are based on Level 3

w.  New Accounting Pronouncements

Recently Adopted Accounting Pronouncements

In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test 

for Goodwill Impairment ("ASU 2017-04"). ASU 2017-04 modifies the process by which entities will test goodwill for 
impairment. Under existing GAAP, when the carrying value of a reporting unit exceeds the reporting unit’s fair value, an entity 
would then proceed to a “Step 2” goodwill impairment analysis, which requires calculating the implied fair value of goodwill 
by assigning the fair value of a reporting unit to all of its assets and liabilities, as if that reporting unit had been acquired in a 
business combination. Under ASU 2017-04, a goodwill impairment will be the amount by which a reporting unit’s carrying 
value exceeds its fair value, not to exceed the carrying value of the reporting unit’s goodwill. We adopted ASU 2017-04 in the 
first quarter of 2017.

In January 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a 
Business ("ASU 2017-01"). ASU 2017-01 provides greater clarity on the definition of a business to assist entities in evaluating 
whether transactions should be accounted for as an acquisition or disposal of assets or businesses. We adopted ASU 2017-01 in 
the third quarter of 2017. ASU 2017-01 did not have a material impact on our consolidated financial statements. 

In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (a Consensus 

of the FASB Emerging Issues Task Force) ("ASU 2016-18"). ASU 2016-18 requires that restricted cash and restricted cash 
equivalents be included with cash and cash equivalents when reconciling the cash and cash equivalents as of the beginning of 
the period to the cash and cash equivalents as of the end of the period in the statement of cash flows. We adopted ASU 2016-18 
during the fourth quarter of 2017 retrospectively for the earliest year presented in our consolidated statement of cash flows. 
ASU 2016-18 did not have a material impact on our consolidated financial statements.

2. Summary of Significant Accounting Policies (Continued)

As Yet Adopted Accounting Pronouncements

a.  ASU 2014-09 

In May 2014, the FASB issued ASU No. 2014-09. ASU 2014-09 provides guidance for revenue recognition as it relates 

to: (1) transfer of control, (2) variable consideration, (3) allocation of transaction price based on relative standalone selling 
price, (4) licenses, (5) time value of money, and (6) contract costs. 

ASU 2014-09 will replace the current revenue recognition criteria under GAAP, including industry-specific requirements, 

and provide companies with a single revenue recognition model for recognizing revenue from contracts with customers. The 
core principle of ASU 2014-09 is that a company should recognize revenue to depict the transfer of promised goods or services 
to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for such 
goods or services. The two permitted transition methods under ASU 2014-09 are: (i) the full retrospective method, whereby 
ASU 2014-09 would be applied to each prior reporting period presented and the cumulative effect of adoption would be 
recognized at the earliest period shown, or (ii) the modified retrospective method, whereby the cumulative effect of applying 
ASU 2014-09 would be recognized at the date of initial application. In August 2015, the FASB issued ASU No. 2015-14, which 
deferred the effective date of ASU 2014-09 for one year, making ASU 2014-09 effective for us on January 1, 2018, with early 
adoption permitted as of January 1, 2017. We will adopt ASU 2014-09 as of January 1, 2018 using the modified retrospective 
method.

During 2015, we established a project team responsible for the assessment and implementation of ASU 2014-09. We 
utilized a bottoms-up approach to analyze the impact of ASU 2014-09 on our contracts with customers by reviewing our current 
accounting policies and practices to identify potential differences that would result from applying the requirements of ASU 
2014-09 to our contracts with customers. We are finalizing our process of designing and implementing appropriate changes to 
our business processes, systems and controls to support the accounting and the financial disclosure requirements under ASU 
2014-09. We have been closely monitoring the FASB activity related to specific interpretative issues pertaining to ASU 
2014-09. During the second half of 2016, we substantially completed our evaluation of the potential changes resulting from the 
adoption of ASU 2014-09 on our accounting and the financial disclosure requirements and are finalizing our assessments of the 
quantification of the impacts of adopting ASU 2014-09 on our consolidated financial statements, the more significant of which 
are discussed below. Based on our analysis to date, we expect that the most significant impacts associated with adopting ASU 
2014-09 compared to current GAAP will relate to (i) the deferral of certain commissions related to our long-term storage 
contracts (“Accounting for Commissions”) and (ii) certain policy changes related to initial moves of physical storage 
(“Accounting for Initial Moves”). Based on our current analysis, on the date of adoption we expect a net decrease to 
(distributions in excess of earnings) earnings in excess of distributions to account for commissions and initial moves in 
accordance with ASU 2014-09 of approximately $17,000 to $21,000. We do not expect the tax impact to be material based on 
our current analysis. 

i. Accounting for Commissions

Under current GAAP, commissions that we pay related to our long-term storage contracts are expensed as incurred. Under 

ASU 2014-09, however, certain commissions will be capitalized and amortized over the period of expected earned revenue. In 
the year of adoption, this will result in increased contract assets on our Consolidated Balance Sheet, a reduction in selling, 
general and administrative expenses and a corresponding increase in amortization expense (assuming consistent levels of 
spending up through the adoption date) on our Consolidated Statement of Operations and an increase in cash flows from 
operating activities and a corresponding increase in cash used for investing activities on our Consolidated Statement of Cash 
Flows. We expect the net commission asset recognized upon adoption to be approximately $28,000 to $32,000. Upon the 
adoption of ASU 2014-09, commissions will be capitalized and amortized over a period of three years.

2. Summary of Significant Accounting Policies (Continued)

ii. Accounting for Initial Moves

Under current GAAP, intake costs incurred but not charged to a customer to transport records to our facilities, which 

include labor and transportation costs, are capitalized and amortized as a component of depreciation and amortization in our 
Consolidated Statements of Operations. Under ASU 2014-09, however, the revenue and costs associated with all initial moves 
of physical storage, regardless of whether or not the services associated with such initial moves are provided to the customer at 
no charge, will be deferred and recognized over the period consistent with the transfer of the service to the customer to which 
the asset relates. In the year of adoption, this will result in decreased assets and increased deferred revenue on our Consolidated 
Balance Sheet, a reduction in cost of sales and a corresponding increase in amortization expense (assuming consistent levels of 
initial move spending through the adoption date) on our Consolidated Statement of Operations and an increase in cash flows 
from operating activities and a corresponding increase in cash used for investing activities on our Consolidated Statement of 
Cash Flows. Upon the adoption of ASU 2014-09, we expect a net decrease to (distributions in excess of earnings) earnings in 
excess of distributions of approximately $30,000 to $34,000 to account for initial moves. This net decrease to (distributions in 
excess of earnings) earnings in excess of distributions represents the write-off of our historical move cost asset associated with 
intake costs incurred but not charged to a customer, which are currently capitalized and amortized over periods ranging from 
five to 30 years, partially offset by the recognition of an asset for all initial move costs, including those that were expensed and 
those that were capitalized and amortized under current GAAP, both of which are expected to be capitalized and amortized over 
a period of three years upon the adoption of ASU 2014-09. At the time of adoption, we expect certain revenues will be deferred 
and recognized over a period of three years under ASU 2014-09 of approximately $15,000 to $19,000.

b.  Other As Yet Adopted Accounting Pronouncements  

In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and 

Measurement of Financial Assets and Financial Liabilities ("ASU 2016-01"). ASU 2016-01 requires that most equity 
investments be measured at fair value, with subsequent changes in fair value recognized in net income, while eliminating the 
available-for-sale classification for equity securities with readily determinable fair values and the cost method for equity 
investments without readily determinable fair values.  ASU 2016-01 also impacts financial liabilities under the fair value option 
and the presentation and disclosure requirements for financial instruments. ASU 2016-01 is effective for us on January 1, 2018. 
We will adopt ASU 2016-01 on January 1, 2018 and are currently evaluating the impact ASU 2016-01 will have on 
our consolidated financial statements.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) ("ASU 2016-02"). ASU 2016-02 requires 
lessees to recognize assets and liabilities on the balance sheet for the rights and obligations created by all leases with terms of 
more than 12 months. ASU 2016-02 also will require certain qualitative and quantitative disclosures designed to give financial 
statement users information on the amount, timing, and uncertainty of cash flows arising from leases. ASU 2016-02 will be 
effective for us on January 1, 2019, with early adoption permitted. We will adopt ASU 2016-02 on January 1, 2019 and are 
currently evaluating the impact ASU 2016-02 will have on our consolidated financial statements.  

In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to 

Accounting for Hedging Activities ("ASU 2017-12"). ASU 2017-12 amends the hedge accounting recognition and presentation 
requirements as outlined in Accounting Standards Codification Topic 815 with the objective of improving the financial 
reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in its financial 
statements and enhance the transparency and understandability of hedge transactions. In addition, ASU 2017-12 simplifies the 
application of the hedge accounting guidance. ASU 2017-12 is effective for us on January 1, 2019, with early adoption 
permitted. We are currently evaluating the impact ASU 2017-12 will have on our consolidated financial statements.

x.  Redeemable Noncontrolling Interests

Certain unaffiliated third parties own noncontrolling interests in our consolidated subsidiaries in Chile, India and South 
Africa. The underlying shareholder 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 shareholder 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.

3. Derivative Instruments and Hedging Activities

Historically, we have entered into forward contracts to hedge our exposures associated with certain foreign currencies. At 

the maturity of the forward contracts, we may enter into new forward contracts to hedge movements in the underlying 
currencies. At the time of settlement, we either pay or receive the net settlement amount from the forward contract and 
recognize this amount in Other expense (income), net in our Consolidated 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. We have not designated any of the forward contracts we have 
entered into as hedges. Our policy is to record the fair value of each derivative instrument on a gross basis. As of December 31, 
2016, we had no forward contracts outstanding. As of December 31, 2017, we had outstanding forward contracts to (i) purchase 
$138,823 United States dollars and sell 176,000 Canadian dollars, (ii) purchase 135,000 Euros and sell $160,757 United States 
dollars and (iii) purchase $114,390 United States dollars and sell 96,150 Euros to hedge our foreign exchange exposures. As of 
December 31, 2017, we recorded a derivative asset of $1,579 as a component of Prepaid expenses and other on our 
Consolidated Balance Sheet and a derivative liability of $2,329 as a component of Accrued expenses on our Consolidated 
Balance Sheet, associated with open forward contracts as of December 31, 2017. 

Net cash payments (receipts) included in cash from operating activities related to settlements associated with foreign 

currency forward contracts for the years ended December 31, 2015, 2016 and 2017, are as follows:

hedge of net investment of certain of our Euro denominated subsidiaries. For the years ended December 31, 2015, 2016 and 
2017, we designated on average 34,331, 29,649 and 103,682 Euros, respectively, of the previously outstanding 63/4% Notes, 
Euro denominated borrowings by IMI under our Former Revolving Credit Facility and 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 the currency translation adjustments, which is a component of accumulated other 
comprehensive items, net:

United States subsidiary guarantors. In addition, Iron Mountain Canada Operations ULC ("Canada Company") has 
pledged 66% of the capital stock of its subsidiaries, and all intercompany obligations (including promissory notes) 
owed to or held by it, to secure the Canadian dollar subfacility under both the Former Revolving Credit Facility and 
the Revolving Credit Facility (as defined below). The fair value (Level 3 of fair value hierarchy described at Note 2.s.) 
of these debt instruments approximates the carrying value (as borrowings under these debt instruments are based on 
current variable market interest rates (plus a margin that is subject to change based on our consolidated leverage 
ratio)), as of December 31, 2016 and 2017, respectively.  

(2)  The fair value (Level 3 of fair value hierarchy described at Note 2.s.) of this debt instrument approximates the carrying 
value as borrowings under this debt instrument are based on a current variable market interest rate. The amount of debt 
for the AUD Term Loan reflects an unamortized original issue discount of $1,725 and $1,545 as of December 31, 2016 
and 2017, respectively.

market prices for these notes on December 31, 2016 and 2017, respectively.

(4)  Collectively, the "Parent Notes". IMI is the direct obligor on the Parent Notes, which are fully and unconditionally 

guaranteed, on a senior or senior subordinated basis, as the case may be, by its direct and indirect 100% owned United 
States subsidiaries that represent the substantial majority of our United States operations (the "Guarantors"). These 
guarantees are joint and several obligations of the Guarantors. Canada Company, Iron Mountain Europe PLC ("IME"), 
IM UK (as defined below), the Accounts Receivable Securitization Special Purpose Subsidiaries (as defined below),

4. Debt (Continued)

(10) Includes (i) real estate mortgages of $20,884 and $20,183 as of December 31, 2016 and 2017, respectively, which bear 
interest at approximately 4.4% as of December 31, 2016 and 4.3% as of December 31, 2017 and are payable in various 
installments through 2021, (ii) capital lease obligations of $309,860 and $436,285 as of December 31, 2016 and 2017, 
respectively, which bear a weighted average interest rate of 4.6% at December 31, 2016 and 4.9% at December 31, 
2017, and (iii) other notes and other obligations, which were assumed by us as a result of certain acquisitions, of 
$147,821 and $192,964 as of December 31, 2016 and 2017, respectively, and bear a weighted average interest rate of 
12.6% at December 31, 2016 and 11.2% at December 31, 2017, respectively. We believe the fair value (Level 3 of fair 
value hierarchy described at Note 2.s.) of this debt approximates its carrying value.  

(11) The Accounts Receivable Securitization Special Purpose Subsidiaries (as defined below) are the obligors under this 

program. We believe the fair value (Level 3 of fair value hierarchy described at Note 2.s.) of this debt approximates its 
carrying value.

(12) The Mortgage Securitization Special Purpose Subsidiary (as defined below) is the obligor under this program. We 
believe the fair value (Level 3 of fair value hierarchy described at Note 2.s.) of this debt approximates its carrying 
value.  

a. Credit Agreement

On August 21, 2017, we entered into a new credit agreement (the "Credit Agreement") which amended and restated our 

then existing credit agreement (the "Former Credit Agreement") which consisted of a revolving credit facility (the "Former 
Revolving Credit Facility") and a term loan (the "Former Term Loan") and was scheduled to terminate on July 6, 2019. The 
Credit Agreement consists of a revolving credit facility (the "Revolving Credit Facility") and a term loan (the "Term Loan"). 
The maximum amount permitted to be borrowed under the Revolving Credit Facility is $1,750,000. The original amount of the 
Term Loan was $250,000. We have the option to request additional commitments of up to $500,000, 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 August 21, 2022, at which point all obligations become due.

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. The Term Loan is to be paid in 
quarterly installments in an amount equal to $3,125 per quarter, with the remaining balance due on August 21, 2022.

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, 2017, we had $466,593 and $243,750 
of outstanding borrowings under the Revolving Credit Facility and the Term Loan, respectively. Of the $466,593 of outstanding 
borrowings under the Revolving Credit Facility, $465,000 was denominated in United States dollars and 2,000 was 
denominated in Canadian dollars. In addition, we also had various outstanding letters of credit totaling $52,847 under the 
Revolving Credit Facility. The remaining amount available for borrowing under the Revolving Credit Facility as of December 
31, 2017, 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 $1,230,560 (which amount represents the maximum availability as of such date). The average interest rate in effect under 
the Credit Agreement was 3.4% as of December 31, 2017. The average interest rate in effect under the Revolving Credit 
Facility was 3.5% and ranged from 3.4% to 5.5% as of December 31, 2017 and the interest rate in effect under the Term Loan 
as of December 31, 2017 was 3.5%. 

The Credit Agreement, our 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 certain other 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 indentures or other 
agreements governing our indebtedness. The Credit Agreement uses EBITDAR-based calculations as the primary measures of 
financial performance, including leverage and fixed charge coverage ratios.

4. Debt (Continued)

Our leverage and fixed charge coverage ratios under the Former Credit Agreement as of December 31, 2016 and the 

Credit Agreement as of December 31, 2017, as well as our leverage ratio under our indentures as of December 31, 2016 and 
2017 are as follows:

Net total lease adjusted leverage ratio

Net secured debt lease adjusted leverage ratio

Bond leverage ratio (not lease adjusted)

Fixed charge coverage ratio

December 31, 2016
5.7

December 31, 2017

Maximum/Minimum Allowable
5.0 Maximum allowable of 6.5(1)(2)

2.7

5.2

2.4

1.6 Maximum allowable of 4.0

5.8 Maximum allowable of 6.5-7.0(3)(4)

2.1 Minimum allowable of 1.5

______________________________________________________________

(1)  Our maximum allowable net total lease adjusted leverage ratio under the Former Credit Agreement was 6.5. The 

Former Credit Agreement also contained a provision which limited, in certain circumstances, our cash dividends in 
any four consecutive fiscal quarters to 95% of Funds From Operations (as defined in the Former Credit Agreement) for 
such four fiscal quarters or, if greater, the amount that we would be required to pay in order to continue to be qualified 
for taxation as a REIT or to avoid the imposition of income or excise taxes on IMI. This former limitation only applied 
in certain circumstances, including where our net total lease adjusted leverage ratio exceeded 6.0 as measured as of the 
end of the most recently completed fiscal quarter (the “Dividend Limitation Leverage Condition”). The Credit 
Agreement does not contain a Dividend Limitation Leverage Condition. The maximum allowable net total lease 
adjusted leverage ratio under the Credit Agreement is 6.5.

(2)  The definition of the net total lease adjusted leverage ratio was modified in the Credit Agreement. The net total lease 
adjusted leverage ratio at December 31, 2017 was calculated as defined in the Credit Agreement, while the net total 
lease adjusted leverage ratio at December 31, 2016 was calculated as defined in the Former Credit Agreement. Had the 
net total lease adjusted leverage ratio at December 31, 2016 been calculated as defined in the Credit Agreement it 
would have been 5.4.

(3)  The maximum allowable leverage ratio under our indenture for the 47/8% Notes, the GBP Notes due 2025 and the 

51/4% Notes is 7.0, while the maximum allowable leverage ratio under the indenture pertaining to our remaining senior 
and senior subordinated notes is 6.5. In certain instances as provided in our indentures, we have the ability to incur 
additional indebtedness that would result in our bond leverage ratio exceeding the maximum allowable ratio under our 
indentures and still remain in compliance with the covenant.

(4)  At December 31, 2017, a portion of the net proceeds from the 51/4% Notes, together with a portion of the net proceeds 
of the Equity Offering, were used to temporarily repay approximately $807,000 of outstanding indebtedness under our 
Revolving Credit Facility until the closing of the IODC Transaction, which occurred on January 10, 2018 (as described 
in Note 6). The bond leverage ratio at December 31, 2017 is calculated based on our outstanding indebtedness at this 
date, which reflects the temporary payment of the Revolving Credit Facility.

Noncompliance with these leverage and fixed charge coverage ratios would have a material adverse effect on our 

financial condition and liquidity.  

Commitment fees and letters of credit fees, which are based on the unused balances under the Former Revolving Credit 

Facility, the Revolving Credit Facility and the Accounts Receivable Securitization Program (as defined below) for the years 
ended December 31, 2015, 2016 and 2017, are as follows:

b.  Bridge Facility

On April 29, 2016, in order to provide a portion of the financing necessary to close the Recall Transaction, we entered into 

a bridge credit agreement (the “Bridge Credit Agreement”) with JPMorgan Chase Bank, N.A., as a lender and administrative 
agent, and the other lenders party thereto (the "Lenders"), pursuant to which we borrowed an unsecured bridge term loan of 
$850,000 (the "Bridge Facility"). We used the proceeds from the Bridge Facility, together with borrowings under the Former 
Revolving Credit Facility, to finance a portion of the cost of the Recall Transaction, including refinancing Recall’s existing 
indebtedness and to pay costs we incurred in connection with the Recall Transaction.

On May 31, 2016, we used the proceeds from the issuance of the 4 % Notes and the 5 % Notes, together with cash on 
hand and borrowings under the Former Revolving Credit Facility, to repay the Bridge Facility, and effective May 31, 2016, we 
terminated the commitments of the Lenders under the Bridge Credit Agreement. We recorded a charge to other expense 
(income), net of $9,283 during the second quarter of 2016 related to the early extinguishment of the Bridge Credit Agreement. 
This charge primarily consisted of the write-off of unamortized deferred financing costs.

c. Notes Issued under Indentures

As of December 31, 2017, we had nine series of senior subordinated or senior notes issued under various indentures, six 

of which are direct obligations of the parent company, IMI; one of which (the 53/8% Notes) is a direct obligation of IM US 
Holdings; one of which (the CAD Notes due 2023) is a direct obligation of Canada Company; and one of which (the GBP  
Notes due 2025) is a direct obligation of IM UK. Each series of notes shown below are pari passu with debt outstanding under 
the Credit Agreement, except the 53/4% Notes which are subordinated to the Credit Agreement:

• 

• 

43/8% Notes: $500,000 principal amount of senior notes maturing on June 1, 2021 and bearing interest at a rate of

• 

• 

• 

53/8% Notes: $250,000 principal amount of senior notes maturing on June 1, 2026 and bearing interest at a rate of

d. Australian Dollar Term Loan

On September 28, 2016, Iron Mountain Australia Group Pty, Ltd., a wholly owned subsidiary of IMI, entered into a 
250,000 Australian dollar Syndicated Term Loan B Facility, the AUD Term Loan, which matures in September 2022. The AUD 
Term Loan was issued at 99% of par. The net proceeds of approximately 243,750 Australian dollars (or approximately 
$185,800, based upon the exchange rate between the Australian dollar and the United States dollar on September 28, 2016 (the 
settlement date for the AUD Term Loan)), after paying commissions to the joint lead arrangers and net of the original discount, 
were used to repay outstanding borrowings under the Former Revolving Credit Facility and for general corporate purposes.

Principal payments on the AUD Term Loan are to be paid in quarterly installments in an amount equivalent to an 

aggregate of 6,250 Australian dollars per year, with the remaining balance due on September 28, 2022. The AUD Term Loan is 
secured by substantially all the assets of Iron Mountain Australia Group Pty. Ltd. IMI and the Guarantors guarantee all 
obligations under the AUD Term Loan. The interest rate on borrowings under the AUD Term Loan is based upon BBSY (an 
Australian benchmark variable interest rate) plus 4.3%. As of December 31, 2016, we had 248,437 Australian dollars ($178,923 
based upon the exchange rate between the United States dollar and the Australian dollar as of December 31, 2016) and as of 
December 31, 2017, we had 242,188 Australian dollars ($189,049 based upon the exchange rate between the United States 
dollar and the Australian dollar as of December 31, 2017) outstanding on the AUD Term Loan. The interest rate in effect under 
the AUD Term Loan was 6.1% as of December 31, 2016 and 2017.

e. Accounts Receivable Securitization Program

In March 2015, we entered into a $250,000 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. Iron Mountain 
Information Management, LLC ("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. As of December 31, 2016, the maximum availability allowed and amount outstanding under the 
Accounts Receivable Securitization Program was $247,000. The interest rate in effect under the Accounts Receivable 
Securitization Program was 1.7% as of December 31, 2016. 

 On July 31, 2017, we amended the Accounts Receivable Securitization Program to (i) increase the maximum amount 

available from $250,000 to $275,000 and (ii) to extend the maturity date from March 6, 2018 to July 30, 2020, at which point 
all obligations become due. As of December 31, 2017, the maximum availability allowed and amount outstanding under the 
Accounts Receivable Securitization Program was $258,973. The interest rate in effect under the Accounts Receivable 
Securitization Program was 2.2% as of December 31, 2017. Commitment fees at a rate of 40 basis points are charged on 
amounts made available but not borrowed under the Accounts Receivable Securitization Program.

f. Mortgage Securitization Program

In October 2016, we entered into a $50,000 mortgage securitization program (the "Mortgage Securitization Program") 
involving certain of our wholly owned subsidiaries with Goldman Sachs Mortgage Company (“Goldman Sachs”). Under the 
Mortgage Securitization Program, IMIM contributed certain real estate assets to its wholly owned special purpose entity, Iron 
Mountain Mortgage Finance I, LLC (the "Mortgage Securitization Special Purpose Subsidiary"). The Mortgage Securitization 
Special Purpose Subsidiary then used the real estate to secure a collateralized loan obtained from Goldman Sachs. The 
Mortgage Securitization Special Purpose Subsidiary is a consolidated subsidiary of IMI. The Mortgage Securitization Program 
is accounted for as a collateralized financing activity, rather than a sale of assets, and therefore: (i) real estate assets pledged as 
collateral remain as assets and borrowings are presented as liabilities on our Consolidated Balance Sheets, (ii) our Consolidated 
Statements of Operations reflects the associated charges for depreciation expense related to the pledged real estate and interest 
expense associated with the collateralized borrowings and (iii) borrowings and repayments under the collateralized loans are 
reflected as financing cash flows within our Consolidated Statements of Cash Flows. The Mortgage Securitization Program is 
scheduled to terminate on November 6, 2026, at which point all obligations become due. The outstanding amount under the 
Mortgage Securitization Program was $50,000 at both December 31, 2016 and 2017. The interest rate in effect under the 
Mortgage Securitization Program was 3.5% as of December 31, 2016 and 2017.

g. Cash Pooling

Certain of our subsidiaries participate in cash pooling arrangements (the “Cash Pools”) with Bank Mendes Gans 
(“BMG”), an independently operated wholly owned subsidiary of ING Group, in order to help manage global liquidity 
requirements. Under the Cash Pools, cash deposited by participating subsidiaries with BMG is 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. At December 31, 2016, we had a net cash 
position of approximately $1,700 (which consisted of a gross cash position of approximately $69,500 less outstanding debit 
balances of approximately $67,800 by participating subsidiaries). 

During the first quarter of 2017, we significantly expanded our utilization of the Cash Pools and reduced our utilization of 

our financing centers in Europe for purposes of meeting our global liquidity requirements. We currently utilize two separate 
cash pools with BMG, one of which we utilize to manage global liquidity requirements for our QRSs (the "QRS Cash Pool") 
and the other for our TRSs (the "TRS Cash Pool"). During the second quarter of 2017, we executed overdraft facility 
agreements for the QRS Cash Pool and 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. As of December 31, 2017, we had a net cash position 
of approximately $5,700 in the QRS Cash Pool (which consisted of a gross cash position of approximately $383,700 less 
outstanding debit balances of approximately $378,000 by participating subsidiaries) and we had a zero balance in the TRS Cash 
Pool (which consisted of a gross cash position of approximately $229,600 less outstanding debit balances of approximately 
$229,600 by participating subsidiaries). The net cash position balances as of December 31, 2016 and 2017 are reflected as cash 
and cash equivalents in the Consolidated Balance Sheets.

5. Selected Consolidated Financial Statements of Parent, Guarantors, Canada Company and Non-Guarantors

The following data summarizes the consolidating results of IMI on the equity method of accounting as of December 31, 

2016 and 2017 and for the years ended December 31, 2015, 2016 and 2017 and are prepared on the same basis as the 
consolidated financial statements.

The Parent Notes, CAD Notes, GBP Notes due 2022, GBP Notes due 2025 and the 53/8% Notes are guaranteed by the 

subsidiaries referred to below as the Guarantors. These subsidiaries are 100% owned by IMI. The guarantees are full and 
unconditional, as well as joint and several. 

Additionally, IMI guarantees the CAD Notes, which were issued by Canada Company, the GBP Notes due 2022, which 
were issued by IME, the GBP Notes due 2025, which were issued by IM UK, and the 53/8% Notes, which were issued by IM 
US Holdings. Canada Company, IME and IM UK do not guarantee the Parent Notes. The subsidiaries that do not guarantee the 
Parent Notes, the CAD Notes, the GBP Notes due 2022, the GBP Notes due 2025, and the 53/8% Notes, including IME, IM UK, 
the Accounts Receivable Securitization Special Purpose Subsidiaries and the Mortgage Securitization Special Purpose 
Subsidiary, are referred to below as the Non-Guarantors. As discussed below, the results of the Non-Guarantors for 2015 and 
2016 exclude the results of Canada Company, as those are presented in a separate column.

The CAD Notes due 2021 were issued by Canada Company and registered under the Securities Act of 1933, as amended 
(the “Securities Act”). The CAD Notes due 2023 have not been registered under the Securities Act, or under the securities laws 
of any other jurisdiction. As disclosed in Note 4, we redeemed the CAD Notes due 2021 in August 2017 and, therefore, as of 
December 31, 2017, Canada Company had no outstanding debt registered under the Securities Act that would require the 
presentation of Canada Company on a standalone basis in the accompanying consolidating financial statements. Accordingly, 
(i) the assets, liabilities and equity of Canada Company are presented as a component of the Non-Guarantor subsidiaries in the 
accompanying Consolidated Balance Sheet as of December 31, 2017, (ii) the revenues, expenses and other comprehensive 
income (loss) of Canada Company are presented as a component of the Non-Guarantor subsidiaries in the Consolidated 
Statement of Operations and Comprehensive Income (Loss) for the year ended December 31, 2017, and (iii) the operating, 
investing and financing cash flows for Canada Company are presented as a component of the Non-Guarantor subsidiaries in the  
Consolidated Statement of Cash Flows for the year ended December 31, 2017. 

In the normal course of business we periodically change the ownership structure of our subsidiaries to meet the 

requirements of our business. In the event of such changes, we recast the prior period financial information within this footnote 
to conform to the current period presentation in the period such changes occur. Generally, these changes do not alter the 
designation of the underlying subsidiaries as Guarantors or Non-Guarantors. However, they may change whether the underlying 
subsidiary is owned by the Parent, a Guarantor, Canada Company or a Non-Guarantor. If such a change occurs, the amount of 
investment in subsidiaries in the below Consolidated Balance Sheets and equity in the earnings (losses) of subsidiaries, net of 
tax in the below Consolidated Statements of Operations and Comprehensive Income (Loss) with respect to the relevant Parent, 
Guarantors, Canada Company, Non-Guarantors and Eliminations columns also would change.

(In thousands, except share and per share data)

6. 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.  Acquisition of Recall

On May 2, 2016 (Sydney, Australia time), we completed the Recall Transaction. At the closing of the Recall Transaction, 
we paid approximately $331,800 in cash and issued 50,233,412 shares of our common stock which, based on the closing price 
of our common stock as of April 29, 2016 (the last day of trading on the NYSE prior to the closing of the Recall Transaction) of 
$36.53 per share, resulted in a total purchase price to Recall shareholders of approximately $2,166,900. 

Regulatory Approvals

In connection with the acquisition of Recall, we sought regulatory approval of the Recall Transaction from the United 

States Department of Justice (the “DOJ”), the Australian Competition and Consumer Commission (the “ACCC”), the Canada 
Competition Bureau (the “CCB”) and the United Kingdom Competition and Markets Authority (the “CMA”).

As part of the regulatory approval process, we agreed to make certain divestments, which are described below in greater 
detail, in order to address competition concerns raised by the DOJ, the ACCC, the CCB and the CMA in respect of the Recall 
Transaction (the “Divestments”). 

See Note 14 for additional information regarding the presentation of the Divestments in our Consolidated Statements of 

Operations and our Consolidated Statements of Cash Flows for the years ended December 31, 2015, 2016 and 2017, 
respectively. 

Divestments  

i.   United States

The DOJ’s approval of the Recall Transaction was subject to the following divestments being made by us following the 

closing of the Recall Transaction:

•  Recall’s records and information management facilities, including all associated tangible and intangible assets, in 
the following 13 United States cities: Buffalo, New York; Charlotte, North Carolina; Detroit, Michigan; Durham, 
North Carolina; Greenville/Spartanburg, South Carolina; Kansas City, Kansas/Missouri; Nashville, Tennessee; 
Pittsburgh, Pennsylvania; Raleigh, North Carolina; Richmond, Virginia; San Antonio, Texas; Tulsa, Oklahoma; and 
San Diego, California (the “Initial United States Divestments”); and

•  Recall’s records and information management facility in Seattle, Washington and certain of Recall’s records and 
information management facilities in Atlanta, Georgia, including in each case associated tangible and intangible 
assets (the “Seattle/Atlanta Divestments”).

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

DECEMBER 31, 2017
(In thousands, except share and per share data)

6. Acquisitions (Continued)

On May 4, 2016, we completed the sale of the Initial United States Divestments to Access CIG, LLC, a privately held 

provider of information management services throughout the United States (“Access CIG”), for total consideration of 
approximately $80,000, subject to adjustments (the “Access Sale”). Of the total consideration, we received $55,000 in cash 
proceeds upon closing of the Access Sale, and we are entitled to receive up to $25,000 of additional cash proceeds (the "Access 
Contingent Consideration") on August 4, 2018, the 27-month anniversary of the closing of the Access Sale. We have recorded a 
non-trade receivable related to our estimate of the Access Contingent Consideration included in Prepaid expenses and other in 
our Consolidated Balance Sheet as of December 31, 2017. The Access Contingent Consideration is subject to adjustments for 
customer attrition subsequent to the closing of the Access Sale and potential indemnity obligations due to Access CIG.

The assets subject to the Access Sale were acquired in the Recall Transaction and, therefore, the estimated fair value of the 
Initial United States Divestments (including the estimated fair value of the Access Contingent Consideration) has been reflected 
in the allocation of the purchase price for Recall as a component of “Fair Value of Recall Divestments”. Our policy related to 
the recognition of contingent consideration (from a seller’s perspective) is to recognize contingent consideration at its estimated 
fair value upon closing of the transaction. Our policy related to the subsequent measurement of contingent consideration (from 
a seller’s perspective) is (i) to recognize contingent consideration in excess of our original estimate of fair value upon cash 
receipt of such consideration and (ii) to recognize any impairment of the contingent consideration compared to our original 
estimate in the period in which we determine such an impairment exists.  

On December 29, 2016, we completed the sale of the Seattle/Atlanta Divestments and the Canadian Divestments (as 

defined below) to Arkive Information Management LLC and Arkive Information Management Ltd., both information 
management companies (collectively, "ARKIVE"), for total consideration of approximately $50,000, subject to adjustments 
(the “ARKIVE Sale”). Of the total consideration, we received approximately $45,000 in cash proceeds upon the closing of the 
ARKIVE Sale and the remaining consideration is held in escrow. ARKIVE may be entitled to receive from us, on the 24-month 
anniversary of the closing of the ARKIVE Sale, cash payments, up to the total consideration paid by ARKIVE, based on lost 
revenues attributable to the acquired customer base. The assets included in the Seattle/Atlanta Divestments and the Recall 
Canadian Divestments (as defined below) were acquired in the Recall Transaction and, therefore, the estimated fair value of the 
Seattle/Atlanta Divestments and the Recall Canadian Divestments (as determined based upon the total consideration for the 
ARKIVE Sale) has been reflected in the allocation of the purchase price for Recall as a component of "Fair Value of Recall 
Divestments".

ii.  Australia

The ACCC approved the Recall Transaction after accepting an undertaking from us pursuant to section 87B of the 
Australian Competition and Consumer Act 2010 (Cth) (the “ACCC Undertaking”). Pursuant to the ACCC Undertaking, we 
agreed to divest the majority of our Australian operations as they existed prior to the closing of the Recall Transaction by way 
of a share sale, which effectively involved the sale of our Australian business (as it existed prior to the closing of the Recall 
Transaction) other than our data management business throughout Australia and our records and information management 
business in the Northern Territory of Australia, except in relation to customers who have holdings in other Australian states or 
territories (the “Australia Divestment Business” and, with respect to the portion of our Australia business that was not subject to 
divestment, the “Australia Retained Business”).

6. Acquisitions (Continued)

On October 31, 2016, after receiving approval of the proposed transaction from the ACCC, we completed the sale of the 

Australia Divestment Business (the “Australia Sale”) to a consortium led by Housatonic Partners (the “Australia Divestment 
Business Purchasers”) for total consideration of approximately 70,000 Australian dollars (or approximately $53,200, based 
upon the exchange rate between the United States dollar and the Australian dollar as of October 31, 2016), subject to 
adjustments. The total consideration consists of (i) 35,000 Australian dollars in cash received upon the closing of the Australia 
Sale and (ii) 35,000 Australian dollars in the form of a note due from the Australia Divestment Business Purchasers to us (the 
“Bridging Loan Note”). The Bridging Loan Note bore interest at 3.3% per annum and matured on December 29, 2017, at which 
point all outstanding obligations became due. During the fourth quarter of 2017, we received proceeds for the full outstanding 
amount of the Bridging Loan Note. The total consideration for the Australia Sale is subject to certain adjustments associated 
with customer attrition subsequent to the closing of the Australia Sale. We recorded a charge of $15,417 to other expense, net 
associated with the loss on disposal of the Australia Divestment Business during the year ended December 31, 2016, 
representing the excess of the carrying value of the Australia Divestment Business compared to its fair value (less costs to sell). 
Approximately $7,099 of cumulative translation adjustment associated with the Australia Divestment Business was reclassified 
from accumulated other comprehensive items, net and reduced the loss recorded on the sale of the Australia Divestment 
Business by the same amount during the year ended December 31, 2016. 

iii.  Canada

The CCB approved the Recall Transaction on the basis of us divesting the following assets:

•  Recall’s record and information management facilities, including associated tangible and intangible assets and 
employees, in Edmonton, Alberta and Montreal (Laval), Quebec and certain of Recall’s record and information 
management facilities, including all associated tangible and intangible assets and employees, in Calgary, Alberta 
and Toronto, Ontario, (the “Recall Canadian Divestments”); and

•  One of our records and information management facilities in Vancouver (Burnaby), British Columbia and one of 

our records and information management facilities in Ottawa, Ontario, including associated tangible and intangible 
assets and employees (the “Iron Mountain Canadian Divestments” and together with the Recall Canadian 
Divestments, the "Canadian Divestments").

On December 29, 2016, we completed the sale of the Canadian Divestments (along with the Seattle/Atlanta Divestments) 

in the ARKIVE Sale, as discussed above. We recorded a charge of $1,421 to other expense, net associated with the loss on 
disposal of the Iron Mountain Canadian Divestments during the year ended December 31, 2016, representing the excess of the 
carrying value of the Iron Mountain Canadian Divestments compared to its fair value (as determined based upon the total 
consideration received in the ARKIVE Sale), less costs to sell.  

iv.  United Kingdom

On June 16, 2016, the CMA published its findings, pursuant to which we agreed to divest Recall’s record and information 
management facilities, including associated tangible and intangible assets and employees, in the Aberdeen and Dundee areas of 
Scotland (the “UK Divestments”). 

On December 9, 2016, we completed the sale of the UK Divestments (the "UK Sale") to the Oasis Group for total 
consideration of approximately 1,800 British pounds sterling (or approximately $2,200, based upon the exchange rate between 
the United States dollar and the British pound sterling as of December 9, 2016), subject to adjustments. The assets included in 
the UK Sale were acquired in the Recall Transaction and, therefore, the estimated fair value of the UK Divestments (as 
determined based upon the total consideration received in the UK Sale) has been reflected in the allocation of the purchase 
price for Recall as a component of “Fair Value of Recall Divestments”.

6. Acquisitions (Continued)

The unaudited consolidated pro forma financial information (the "Pro Forma Financial Information") below summarizes 

the combined results of us and Recall on a pro forma basis as if the Recall Transaction had occurred on January 1, 2015. The 
Pro Forma Financial Information is presented for informational purposes and is not necessarily indicative of the results of 
operations that would have been achieved if the acquisition had taken place on January 1, 2015. The Pro Forma Financial 
Information, for all periods presented, includes adjustments to convert Recall's historical results from International Financial 
Reporting Standards to GAAP, purchase accounting adjustments (including amortization of acquired intangible assets, 
depreciation of acquired property, plant and equipment and amortization of favorable and unfavorable leases), stock-based 
compensation and related tax effects. Through December 31, 2017, we and Recall have collectively incurred $140,661 of 
operating expenditures to complete the Recall Transaction (including advisory and professional fees and costs to complete the 
Divestments and to provide transitional services required to support the divested businesses during a transition period). These 
operating expenditures have been reflected within the results of operations in the Pro Forma Financial Information as if they 
were incurred on January 1, 2015. The costs we have incurred to integrate Recall with our existing operations (including 
moving, severance, facility upgrade, REIT conversion and system upgrade costs) are reflected in the Pro Forma Financial 
Information in the period in which they were incurred.

The Pro Forma Financial Information, for all periods presented, excludes from income (loss) from continuing operations 

the results of operations of the Initial United States Divestments, the Seattle/Atlanta Divestments, the Recall Canadian 
Divestments and the UK Divestments, as these businesses are presented as discontinued operations. See Note 14 for 
information regarding our conclusion with respect to the presentation of these divestments as discontinued operations. The 
results of the Australia Divestment Business and the Iron Mountain Canadian Divestments are included within the results from 
continuing operations in the Pro Forma Financial Information through the closing date of the Australia Sale, in the case of the 
Australia Divestment Business, and through the closing date of the ARKIVE Sale, in the case of the Iron Mountain Canadian 
Divestments, as these businesses do not qualify for discontinued operations. See Note 14 for information regarding our 
conclusion that these divestments do not meet the criteria to be reported as discontinued operations. The Australia Divestment 
Business and the Iron Mountain Canadian Divestments, collectively, represent $67,696 of total revenues and $7,336 of total 
income from continuing operations for the year ended December 31, 2015, respectively, and $46,655 of total revenues and 
$2,603 of total income from continuing operations for the year ended December 31, 2016, respectively.

The amount of revenue and earnings in our Consolidated Statements of Operations for the years ended December 31, 

2016 and 2017 related to Recall is impracticable for us to determine. Subsequent to the closing of the Recall Transaction, we 
began integrating Recall and our existing operations in order to achieve operational synergies. As a result, the revenue 
generated by Recall, as well as the underlying costs of sales and selling, general and administrative expenses to support Recall's 
business, are now integrated with the revenue we generate, as well as the costs of sales and selling, general and administrative 
expenses that supported our business, prior to the acquisition of Recall.

In addition to our acquisition of Recall, we completed certain other acquisitions during 2015, 2016 and 2017. The Pro 
Forma Financial Information does not reflect these acquisitions due to the insignificant impact of these acquisitions on our 
consolidated results of operations.

b.  Other Noteworthy Acquisitions

Acquisitions Completed During the Year Ended December 31, 2015

In December 2015, in order to expand our offerings in our Adjacent Businesses operating segment, we acquired Crozier 
Fine Arts ("Crozier"), a storage, logistics and transportation business for high value paintings, photographs and other types of 
art belonging to individual collectors, galleries and art museums for approximately $74,200.  

In December 2015, in order to enhance our existing operations in India, we acquired the stock of Navbharat Archive 
XPress Private Limited ("NAX"), a storage and records management company with operations in India, for approximately 
$16,100. Of the total consideration, approximately $8,900 was funded by us, while the remaining $7,200 was contributed by the 
noncontrolling interest shareholder of our business in India. The amount contributed by our noncontrolling interest shareholder 
is presented as source of cash within debt financing and equity contribution from noncontrolling interests in our Consolidated 
Statement of Cash Flows for the year ended December 31, 2015. 

In addition to the acquisitions of Crozier and NAX noted above, during 2015, in order to enhance our existing operations 

in Australia, Austria, Canada, Chile, Hungary, India, Serbia, the United Kingdom and the United States, we completed 12 
acquisitions for total consideration of approximately $27,600. These acquisitions included nine storage and records 
management companies, two storage and data management companies and one personal storage company. The individual 
purchase prices of these acquisitions ranged from approximately $1,000 to $5,400. 

Acquisitions Completed During the Year Ended December 31, 2016 

In March 2016, we acquired a controlling interest in Docufile Holdings Proprietary Limited ("Docufile"), a storage and 

records management company with operations in South Africa, for approximately $15,000. The acquisition of Docufile 
represents our entrance into Africa.

In March 2016, in order to expand our presence in the Baltic region, we acquired the stock of Archyvu Sistemos, a 

storage and records management company with operations in Lithuania, Latvia and Estonia, for approximately $5,100.

In November 2016, we entered into a binding agreement to acquire the storage and information management assets and 

operations of Santa Fe Group A/S ("Santa Fe") in ten regions within Europe and Asia in order to expand our presence in 
southeast Asia and western Europe. In December 2016, we acquired the storage and information management assets and 
operations of Santa Fe in Hong Kong, Malaysia, Singapore, Spain and Taiwan (the “2016 Santa Fe Transaction”) for 
approximately 15,200 Euros (or approximately $16,000, based upon the exchange rate between the United States dollar and the 
Euro as of December 30, 2016, the closing date of the 2016 Santa Fe Transaction). Of the total purchase price, 13,500 Euros (or 
approximately $14,200, based upon the exchange rate between the United States dollar and the Euro on the closing date of the 
2016 Santa Fe Transaction) was paid during the year ended December 31, 2016, and the remaining balance is due on the 18-
month anniversary of the closing of the 2016 Santa Fe Transaction.

6. Acquisitions (Continued)

Acquisitions Completed During the Year Ended December 31, 2017

During the first half of 2017, we acquired, in two separate transactions, (i) the storage and information management 
assets and operations of Santa Fe in Macau and South Korea, and (ii) the storage and information management assets and 
operations of Santa Fe in India, Indonesia and the Philippines (collectively, the “2017 Santa Fe Transaction”) for an aggregate 
cash purchase price of approximately 11,700 Euros (or approximately $13,000, based upon the exchange rate between the 
United States dollar and the Euro on the closing dates of the respective transactions).

In November 2017, we entered into an agreement to acquire (i) the storage and information management assets and 
operations of Santa Fe in China (the “Santa Fe China Transaction”) for approximately 14,000 Euros and (ii) certain real estate 
property located in Beijing, China owned by Santa Fe (the “Beijing Property”) for approximately 9,000 Euros, representing a 
total purchase price of approximately 23,000 Euros, subject to customary purchase price adjustments. On December 29, 2017, 
we closed on the Santa Fe China Transaction. The purchase price for the Santa Fe China Transaction was not paid until January 
2018 and, therefore, we have accrued for the purchase price of the Santa Fe China Transaction (which was approximately 
$16,800, based upon the exchange rate between the Euro and the United States dollar on the closing date of the Santa Fe China 
Transaction) in our Consolidated Balance Sheet as of December 31, 2017 (the “Accrued Purchase Price”). The Accrued 
Purchase Price is presented as a component of the current portion of long-term debt in our Consolidated Balance Sheet as of 
December 31, 2017. We expect to close on the acquisition of the Beijing Property during the first half of 2018. The completion 
of the acquisition of the Beijing Property is subject to closing conditions; accordingly, we can provide no assurances that we 
will be able to complete the acquisition of the Beijing Property, that it will not be delayed or that the terms will remain the 
same. 

In June 2017, in order to expand our presence in Peru, we acquired the storage and information management assets and 

operations of Ransa Comercial, S.A. and Depositos, S.A. (the "Ransa and Depositos Transaction"), two records and storage and 
information management companies with operations in Peru, for approximately $14,700.

In July 2017, in order to expand our European operations, we acquired Fileminders Ltd., a storage and records 

management company with operations in Cyprus (the "Fileminders Transaction"), for approximately 24,900 Euros (or 
approximately $28,500, based upon the exchange rate between the United States dollar and the Euro on the closing date of the 
acquisition).

In September 2017, in order to expand our data center operations in the United States, we acquired Mag Datacenters LLC, 
which operated Fortrust, a private data center business with operations in Denver, Colorado (the “Fortrust Transaction”). At the 
closing of the Fortrust Transaction, we paid approximately $54,500 in cash (the "Fortrust Cash Consideration") and issued 
2,193,637 shares of our common stock (the "Fortrust Stock Consideration"). The shares of our common stock issued to the 
former owners of Fortrust in connection with the Fortrust Transaction contain certain restrictions that impact the marketability 
of such shares for a period of six months following the closing date of the Fortrust Transaction (the “Lack of Marketability 
Restriction”). The 2,193,637 shares issued as part of the Fortrust Stock Consideration were valued at approximately $37.84 per 
share, which represents the closing price of our common stock as of August 31, 2017 (the last day of trading on the NYSE prior 
to the closing of the Fortrust Transaction), discounted for the Lack of Marketability Restriction, resulting in a total purchase 
price (including the Fortrust Cash Consideration and the Fortrust Stock Consideration) of approximately $137,500.   

In September 2017, in order to expand our existing entertainment storage and services operations in the United States and 

to expand our entertainment storage and services operations into Canada, the United Kingdom, France, the Netherlands and 
Hong Kong, we completed the acquisition of Bonded Services of America, Inc. and Bonded Services Acquisition, Ltd. 
(together, "Bonded") (the "Bonded Transaction"), providers of media asset storage and management services for global 
entertainment and media companies, for approximately 62,000 British pounds sterling (or approximately $83,000, based upon 
the exchange rate between the British pound sterling and the United States dollar on the closing date of the Bonded 
Transaction).

In October 2017, in order to expand our presence in India, we acquired OEC Records Management, a storage and 

information management company with operations in India (the "OEC Transaction") for approximately $19,300.

In addition to the transactions noted above, during 2017, in order to enhance our existing operations in the United States, 

Greece and South Africa and to expand our operations into the United Arab Emirates, we completed the acquisition of five 
storage and records management companies, one storage and data management company and one art storage company for total 
consideration of approximately $22,700. The individual purchase prices of these acquisitions were each less than $5,000.

6. Acquisitions (Continued)

(5)  The weighted average lives of customer relationship intangible assets associated with acquisitions in 2015, 2016 and 

2017 was 16 years, 13 years and 12 years, respectively.

(6)  The goodwill associated with acquisitions, including Recall, is primarily attributable to the assembled workforce, 
expanded market opportunities and costs and other operating synergies anticipated upon the integration of the 
operations of us and the acquired businesses.

Allocations of the purchase price for acquisitions made in 2015, 2016 and 2017 were 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. Assets and liabilities that were acquired 
and classified as held for sale immediately following the Recall Transaction were valued based on the estimated fair value of 
the divestment, less costs to sell. The preliminary purchase price allocations that are not finalized as of December 31, 2017 
primarily relate to the final assessment of the fair values of intangible assets (primarily customer relationship intangible assets 
and acquired in-place lease value), property, plant and equipment (primarily building, building improvements and racking 
structures), operating leases, contingencies and income taxes (primarily deferred income taxes), primarily associated with the 
Santa Fe China Transaction, the Fortrust Transaction, the Bonded Transaction and the OEC Transaction.

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 2017 were not 
material to our results from operations.

c.   Acquisitions Closed or Expected to Close in 2018

On December 11, 2017, we entered into a purchase agreement to acquire the United States operations of IO Data Centers, 
LLC (“IODC”), a leading data center colocation space and solutions provider based in Phoenix, Arizona, including the land and 
buildings associated with four data centers in Phoenix and Scottsdale, Arizona; Edison, New Jersey; and Columbus, Ohio, for 
an aggregate cash purchase price of $1,315,000 (the “Initial IODC Consideration”), plus up to $60,000 of additional proceeds 
(including (i) $25,000 of contingent consideration (the “IODC Contingent Consideration”) and (ii) $35,000 of contingent 
payments associated with the execution of future customer contracts), subject to certain adjustments as set forth in the IODC 
Purchase Agreement (the “IODC Transaction”).  

On January 10, 2018, we completed the IODC Transaction. At the closing of the IODC Transaction, we paid 
approximately $1,340,000 of total consideration, consisting of the Initial IODC Consideration and the IODC Contingent 
Consideration. The proceeds for the IODC Transaction were provided by the Equity Offering, the Over-Allotment Option (each 
as defined in Note 13) and the issuance of the 5¼% Notes. At December 31, 2017, the net proceeds from the 51/4% Notes and 
the Equity Offering were used to temporarily repay borrowings under our Revolving Credit Facility and invest in money market 
funds. At the closing of the IODC Transaction, we utilized the cash in the money market funds and additional borrowings under 
our Revolving Credit Facility to finance the purchase price of the IODC Transaction.

6. Acquisitions (Continued)

Due to the recent timing of the closing of the IODC Transaction, we are in the preliminary stages of the valuations of the 

assets and liabilities for purposes of purchase price allocations and it is not yet practical for us to provide consolidated pro 
forma financial information which summarizes the combined results of us and IODC on a pro forma basis as if the IODC 
Transaction had occurred on January 1, 2016.  We expect that the majority of the total consideration paid for the IODC 
Transaction will be allocated to property, plant and equipment and intangible assets on our consolidated balance sheet upon the 
completion of the valuation of the acquired assets and liabilities of IODC for purposes of purchase price allocations.

In October 2017, we entered into agreements to acquire two data centers located in London and Singapore from Credit 
Suisse International and Credit Suisse AG (together, "Credit Suisse") for an aggregate cash purchase price of approximately 
$100,000 (the “Credit Suisse Transaction”). As part of the Credit Suisse Transaction, we will take ownership of both data center 
facilities, with Credit Suisse entering into a long-term lease with us to maintain existing data center operations. The completion 
of the Credit Suisse Transaction is subject to closing conditions; accordingly, we can provide no assurance that we will be able 
to complete the Credit Suisse Transaction, that the Credit Suisse Transaction will not be delayed or that the terms will remain 
the same. We expect to close the Credit Suisse Transaction during the first half of 2018.

7. 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 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 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 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 following the date on which that asset 
was first owned by a REIT that are attributable to "built-in" gains with respect to that asset on that date (e.g. with respect to the 
REIT conversion, the assets that we owned on January 1, 2014). This built-in gains tax has been imposed on our depreciation 
recapture recognized into income as a result of accounting method changes commenced in our pre-REIT period and in 
connection with the Recall Transaction. 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.

On December 22, 2017, the Tax Cuts and Jobs Act (the “Tax Reform Legislation”) was enacted into law in the United 

States. The Tax Reform Legislation amends the Internal Revenue Code of 1986, as amended (the “Code”), to reduce tax rates 
and modify policies, credits and deductions for businesses and individuals. The following summarizes certain components of 
the Tax Reform Legislation and the impact such components of the Tax Reform Legislation had on our results of operations for 
the taxable year ended December 31, 2017: 

a.  Corporate Tax Rate Reduction

The Tax Reform Legislation reduced the United States corporate federal income tax rate from 35% to 21% for taxable 

years beginning after December 31, 2017 (the “U.S. Federal Rate Reduction”). Our deferred tax assets and liabilities are 
measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are 
expected to be realized or settled. As a result of the Tax Reform Legislation being enacted prior to December 31, 2017, our 
consolidated balance sheet as of December 31, 2017 reflects the revaluation of our deferred tax assets and liabilities based upon 
the U.S. Federal Rate Reduction. During the fourth quarter of 2017, we recorded a discrete tax benefit of approximately $4,685, 
representing the revaluation of our deferred tax assets and liabilities as a result of the U.S. Federal Rate Reduction included in 
the Tax Reform Legislation.

7. Income Taxes (Continued)

b.  Deemed Repatriation Transition Tax

The Tax Reform Legislation imposes a transition tax (the “Deemed Repatriation Transition Tax”) on a mandatory deemed 
repatriation of post-1986 undistributed foreign earnings and profits not previously subject to United States tax as of November 
2, 2017 or December 31, 2017, whichever is greater (the “Undistributed E&P”) as of the last taxable year beginning before 
January 1, 2018. The Deemed Repatriation Transition Tax varies depending on whether the Undistributed E&P is held in liquid 
(as defined in the Tax Reform Legislation) or non-liquid assets. A participation deduction against the deemed repatriation will 
result in a Deemed Repatriation Transition Tax on Undistributed E&P of 15.5% if held in cash and liquid assets and 8% if held 
in non-liquid assets. The Deemed Repatriation Transition Tax applies regardless of whether or not an entity has cash in its 
foreign subsidiaries and regardless of whether the entity actually repatriates the Undistributed E&P back to the United States.

Our current estimate of the amount of Undistributed E&P deemed repatriated under the Tax Reform Legislation in our 
taxable year ending December 31, 2017 is approximately $186,000 (the “Estimated Undistributed E&P”). We have opted to 
include the full amount of Estimated Undistributed E&P in our 2017 taxable income, rather than spread it over eight years (as 
permitted by the Tax Reform Legislation). Accordingly, included in our REIT taxable income for 2017 is approximately 
$82,000 related to the deemed repatriation of Undistributed E&P (the “Deemed Repatriation Taxable Income”). 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 gains) each year to our stockholders.

Our current estimate of Estimated Undistributed E&P includes certain assumptions made by us regarding the cumulative 

earnings and profits of our foreign subsidiaries, as well as the characterization of such Estimated Undistributed E&P (liquid 
versus non-liquid assets). In 2018, we will perform additional analysis to determine the actual amount of Undistributed E&P 
associated with our foreign subsidiaries, as well as the characterization of such Undistributed E&P. We do not believe this will 
have an impact on our provision for income taxes or our qualification as a REIT. However, it may impact our shareholder 
dividend reporting.

2017 to reduce future federal taxable income, of which $1,662 of federal tax benefit is expected to be realized. We can carry 
forward these net operating losses to the extent we do not utilize them in any given available year. We have state net operating 
loss carryforwards, which expire from 2018 through 2036, of which an insignificant state tax benefit is expected to be realized. 
We have assets for foreign net operating losses of $103,550, with various expiration dates (and in some cases no expiration 
date), subject to a valuation allowance of approximately 59%.

Our effective tax rates for the years ended December 31, 2015, 2016 and 2017 were 23.3%, 30.6% and 12.0%, 
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 qualified REIT subsidiaries 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 former federal statutory tax rate of 35.0% and our overall effective tax rate for 
the year ended December 31, 2015 were the benefit derived from the dividends paid deduction of $51,625 and an out-of-period 
tax adjustment ($9,067 tax benefit) recorded during the third quarter to correct the valuation of certain deferred tax assets 
associated with the REIT conversion that occurred in 2014, partially offset by valuation allowances on certain of our foreign net 
operating losses of $33,509, primarily related to our foreign subsidiaries in Argentina, Brazil, France and Russia.

7. Income Taxes (Continued)

The primary reconciling items between the former federal statutory tax rate of 35.0% and our overall effective tax rate for 

the year ended December 31, 2016 were the benefit derived from the dividends paid deduction of $18,526 and the impact of 
differences in the tax rates at which our foreign earnings are subject resulting in a tax benefit of $13,328, partially offset by 
valuation allowances on certain of our foreign net operating losses of $7,660. 

The primary reconciling items between the former federal statutory tax rate of 35.0% and our overall effective tax rate for 

the year ended December 31, 2017 were the benefit derived from the dividends paid deduction of $78,873, the impact of 
differences in the tax rates at which our foreign earnings are subject resulting in a tax benefit of $11,949, and a release of 
valuation allowances on certain of our foreign net operating losses of $4,317 as a result of the merger of certain of our foreign 
subsidiaries, partially offset by the impact of the Tax Reform Legislation of $24,791 (reflecting the impact of the Deemed 
Repatriation Transition Tax, partially offset by the impact of the U.S. Federal Rate Reduction).

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.

During 2016, as a result of the closing of the Recall Transaction and the subsequent integration of Recall’s operations into 
our operations, we reassessed our intentions regarding the indefinite reinvestment of such undistributed earnings of our foreign 
subsidiaries outside the United States (the “2016 Indefinite Reinvestment Assessment”). As a result of the 2016 Indefinite 
Reinvestment Assessment, we concluded that it is our intent to indefinitely reinvest our current and future undistributed 
earnings of certain of our unconverted foreign taxable REIT subsidiaries (“TRSs”) outside the United States and, therefore, 
during 2016, we recognized a decrease in our provision for income taxes from continuing operations in the amount of $3,260, 
representing the reversal of previously recognized incremental foreign withholding taxes on the earnings of such unconverted 
foreign TRSs. As a result of the 2016 Indefinite Reinvestment Assessment, we no longer provide incremental foreign 
withholding taxes on the retained book earnings of these unconverted foreign TRSs, which was approximately $230,000 as of 
December 31, 2017. 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 in limited instances; however, such future 
repatriations will require distribution in accordance with REIT distribution rules, and any such distribution may then be taxable, 
as appropriate, at the stockholder level. We continue, however, to provide for incremental foreign withholding taxes on net book 
over outside basis differences related to the earnings of our foreign qualified REIT subsidiaries and certain other foreign TRSs 
(excluding unconverted foreign TRSs).

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  
(benefit) provision for income taxes in the accompanying Consolidated Statements of Operations. We recorded an increase of 
$2,173, $1,805 and $289 for gross interest and penalties for the years ended December 31, 2015, 2016 and 2017, respectively. 
We had $8,646 and $7,061 accrued for the payment of interest and penalties as of December 31, 2016 and 2017, respectively.

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

7. 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 2014, 2015 and 2016 tax years remain subject to examination for United States federal tax 
purposes as well as net operating loss carryforwards utilized in these years. We utilized net operating losses from 2001 and 
2008 through 2014 in our federal income tax returns for these tax 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, 2016, 
we had $59,466 of reserves related to uncertain tax positions, of which $56,303 and $3,163 is included in other long-term 
liabilities and deferred income taxes, respectively, in the accompanying Consolidated Balance Sheet. As of December 31, 2017, 
we had $38,533 of reserves related to uncertain tax positions, of which $34,003 and $4,530 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, 2014

Gross additions for tax positions of prior years

7. Income Taxes (Continued)

(1)  This amount includes gross additions related to the Recall Transaction.  

The reversal of these reserves of $38,533 ($35,776 net of federal tax benefit) as of December 31, 2017 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 $4,524 of our unrecognized tax positions may be recognized by the end of 2018 as a result of a lapse of statute 
of limitations or upon closing and settling significant audits in various worldwide jurisdictions. Additionally, we believe that it 
is reasonably possible that an amount up to $14,020, which is included as a component of accrued expenses (and not included 
in the above table) in our Consolidated Balance Sheet as of December 31, 2017, could be released by the end of 2018 as a result 
of the resolution of a tax matter.

8. Quarterly Results of Operations (Unaudited) (Continued)

(1)  The change in net income (loss) attributable to Iron Mountain Incorporated in the fourth quarter of 2016 compared to 
the third quarter of 2016 is primarily attributable to a decrease in the provision for income taxes recorded in the fourth 
quarter of 2016 compared to the third quarter of 2016 of approximately $24,600, a charge of $14,000 recorded in the 
third quarter of 2016 associated with the anticipated loss on disposal of the Australia Divestment Business, which 
occurred on October 31, 2016 (as described in Note 6), and a decrease in loss on foreign currency transaction losses 
recorded in the fourth quarter of 2016 compared to the third quarter of 2016 of approximately $5,600.  

(2)  The change in net income (loss) attributable to Iron Mountain Incorporated in the fourth quarter of 2017 compared to 
the third quarter of 2017 is primarily attributable to increases in operating expenses, primarily associated with 
increased Recall Costs and bad debt expenses, as well as a $3,011 intangible impairment charge recorded during the 
fourth quarter of 2017. This increase in operating expenses was partially offset by a decrease in debt extinguishment 
expense in the fourth quarter of 2017 compared to the third quarter of 2017 of approximately $18,200, as well as a 
decrease in the provision for income taxes recorded in the fourth quarter of 2017 compared to the third quarter of 2017 
of approximately $5,800. The decrease in the tax provision is primarily attributable to benefits derived from (i) rate 
changes as a result of the Tax Reform Legislation, (ii) the release of reserves and benefits recorded as a result of 
closing tax years; and (iii) the change in our estimated annual effective tax rate, which were partially offset by a 
provision related to the establishment of a valuation allowance on certain of our foreign net operating losses in Brazil.

9. Segment Information

During the fourth quarter of 2017, as a result of changes in the management of our entertainment storage and services 

business, we reassessed the composition of our reportable operating segments. As a result of this reassessment, we determined 
that our entertainment storage and services business in the United States and Canada, which were previously included within 
our North American Data Management Business segment, were now being managed in conjunction with our entertainment 
storage and services business in France, Hong Kong, the Netherlands and the United Kingdom (the majority of which were 
acquired in the third quarter of 2017 as part of the Bonded Transaction) as a component of our Adjacent Businesses operating 
segment which is included within our Corporate and Other Business reportable operating segment.   

Additionally, during the fourth quarter of 2017, we determined that our global data center business was now being 
managed as a separate operating segment, rather than as a component of our Adjacent Businesses operating segment. We now 
present our Global Data Center Business operating segment as a separate reportable operating segment. 

As a result of the changes noted above, previously reported segment information has been restated to conform to the 

current presentation.

As of December 31, 2017, our six reportable operating segments are described as follows:

•  North American Records and Information Management Business—provides records and information management 

services, including the storage of physical records, including media such as microfilm and microfiche, master audio 
and videotapes, film, X-rays and blueprints, including healthcare information services, vital records services, service 
and courier operations, and the collection, handling and disposal of sensitive documents for corporate customers 
(“Records Management”); information destruction services (“Destruction”); and Information Governance and Digital 
Solutions throughout the United States and Canada; as well as fulfillment services and technology escrow services in 
the United States.  

•  North American Data Management Business—provides storage and rotation of backup computer media as part of 

corporate disaster recovery plans, including service and courier operations (“Data Protection & Recovery”); server and 
computer backup services; and related services offerings including our Iron Cloud solutions. 

•  Western European Business—provides records and information management services, including Records 

Management, Data Protection & Recovery and Information Governance and Digital Solutions throughout Austria, 
Belgium, France, Germany, Ireland, the Netherlands, Spain, Switzerland and the United Kingdom (consisting of our 
operations in England, Northern Ireland and Scotland), as well as Information Governance and Digital Solutions in 
Sweden (the remainder of our business in Sweden is included in the Other International Business segment described 
below).

•  Other International Business—provides records and information management services throughout the remaining 
European countries in which we operate, Latin America, Asia and Africa, including Records Management, Data 
Protection & Recovery and Information Governance and Digital Solutions. Our European operations included in this 
segment provide records and information management services, including Records Management, Data Protection & 
Recovery and Information Governance and Digital Solutions throughout Cyprus, the Czech Republic, Denmark, 
Finland, Greece, Hungary, Norway, Poland, Romania, Serbia, Slovakia, and Turkey; Records Management and 
Information Governance and Digital Solutions in Estonia, Latvia and Lithuania; and Records Management in Sweden. 
Our Latin America operations provide records and information management services, including Records Management, 
Data Protection & Recovery, Destruction and Information Governance and Digital Solutions throughout Argentina, 
Brazil, Chile, Colombia, Mexico and Peru. Our Asia operations provide records and information management services, 
including Records Management, Data Protection & Recovery, Destruction and Information Governance and Digital 
Solutions throughout Australia and New Zealand, with Records Management and Data Protection & Recovery also 
provided in certain markets in China (including Taiwan and Macau), Hong Kong, India, Indonesia, Malaysia, the 
Philippines, Singapore, South Korea, Thailand and United Arab Emirates. Our African operations provide Records 
Management, Data Protection & Recovery, and Information Governance and Digital Solutions in South Africa. 

•  Global Data Center Business—provides data center facilities to protect mission-critical assets and ensure the continued 

operation of our customers’ IT infrastructures, with secure and reliable colocation and wholesale options. As of 
December 31, 2017, we have data center operations in five markets in the United States including: Denver, Colorado; 
Kansas City, Missouri; Boston, Massachusetts; Boyers, Pennsylvania; and Manassas,Virginia.

9. Segment Information (Continued)

•  Corporate and Other Business—primarily consists of the storage, safeguarding and electronic or physical delivery of 
physical media of all types and digital content repository systems to house, distribute, and archive key media assets, 
primarily for entertainment and media industry clients throughout the United States, Canada, France, Hong Kong, the 
Netherlands and the United Kingdom, as well as our fine art and consumer storage businesses, the primary product 
offerings of our Adjacent Businesses operating segment, as well as costs related to executive and staff functions, 
including finance, human resources and IT, which benefit the enterprise as a whole. These costs are primarily related to 
the general management of these functions on a corporate level and the design and development of programs, policies 
and procedures that are then implemented in the individual segments, with each segment bearing its own cost of 
implementation. Our Corporate and Other Business segment also includes stock-based employee compensation 
expense associated with all Employee Stock-Based Awards.

9. Segment Information (Continued)

(2)  Cash paid for acquisitions, net of cash acquired for the Other International Business segment for the year ended 

December 31, 2016 primarily consists of the cash component of the purchase price for the Recall Transaction, as the 
IMI entity that made the cash payment was an Australian subsidiary. However, the Recall Transaction also benefited 
the North American Records and Information Management Business, North American Data Management Business and 
Western European Business segments.   

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, and also excludes certain items that we believe are not indicative of our core operating 
results, specifically: (1) loss (gain) on disposal/write-down of property, plant and equipment (excluding real estate), net; (2) 
intangible impairments; (3) other expense (income), net; (4) gain on sale of real estate, net of tax; and (5) Recall 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 Adjusted EBITDA to income (loss) from continuing operations on a consolidated basis is as follows:

Adjusted EBITDA

(Add)/Deduct:

Gain on Sale of Real Estate, Net of Tax

Provision (Benefit) for Income Taxes

Other Expense, Net

Interest Expense, Net

Loss (Gain) on Disposal/Write-down of Property, Plant and Equipment
(Excluding Real Estate), Net

10. Commitments and Contingencies 

a.  Leases

Most of our leased facilities are leased under various operating leases that typically have initial lease terms of five to ten 

years. A majority of these leases have renewal options with one or more five-year options to extend and may have fixed or 
Consumer Price Index escalation clauses. We also lease equipment under operating leases (primarily computers) which have an 
average lease life of three years. Vehicles and office equipment are also leased and have remaining lease lives ranging from one 
to seven years. Total rent expense under all of our operating leases was $242,205, $321,337 and $350,403 for the years ended 
December 31, 2015, 2016 and 2017, respectively.

Estimated minimum future lease payments (excluding common area maintenance charges) include payments for certain 

renewal periods at our option because failure to renew results in an economic disincentive due to significant capital expenditure 
costs (e.g., racking structures), thereby making it reasonably assured that we will renew the lease. Such payments in effect at 
December 31, are as follows:

10. Commitments and Contingencies (Continued)

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, 2016 and 2017 there were $37,368 and $38,460, 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 ultimate claim costs based on claims incurred as of the balance 
sheet date.

c.   Litigation—General

We are involved in litigation from time to time in the ordinary course of business. A portion of the defense and/or 
settlement costs 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. The matters described below represent our significant loss contingencies. We have evaluated 
each matter and, if both probable and estimable, accrued an amount that represents our estimate of any probable loss associated 
with such matter. In addition, we have estimated a reasonably possible range for all loss contingencies including those 
described below. We believe it is reasonably possible that we could incur aggregate losses in addition to amounts currently 
accrued for all matters up to an additional $21,500 over the next several years, of which certain amounts would be covered by 
insurance or indemnity arrangements.

d.   Italy Fire

On November 4, 2011, we experienced a fire at a facility we leased in Aprilia, Italy. The facility primarily stored archival 
and inactive business records for local area businesses. Despite quick response by local fire authorities, damage to the building 
was extensive, and the building and its contents were a total loss. We have been sued by six customers. Four of those lawsuits 
have been settled and two remain pending, including a claim asserted by Azienda per i Transporti Autoferrotranviari del 
Comune di Roma, S.p.A, seeking 42,600 Euros for the loss of its current and historical archives. We have also received 
correspondence from other affected customers, including certain customers demanding payment under various theories of 
liability. Although our warehouse legal liability insurer has reserved its rights to contest coverage related to certain types of 
potential claims, we believe we carry adequate insurance. We deny any liability with respect to the fire and we have referred 
these claims to our warehouse legal liability insurer for an appropriate response. We do not expect that this event will have a 
material impact on our consolidated financial condition, results of operations or cash flows. We sold our Italian operations on 
April 27, 2012, and we indemnified the buyers related to certain obligations and contingencies associated with this fire. As a 
result of the sale of the Italian operations, any future statement of operations and cash flow impacts related to the fire will be 
reflected as discontinued operations. 

e.   Argentina Fire

On February 5, 2014, we experienced a fire at a facility we own in Buenos Aires, Argentina. As a result of the quick 
response by local fire authorities, the fire was contained before the entire facility was destroyed and all employees were safely 
evacuated; however, a number of first responders lost their lives, or in some cases, were severely injured. The cause of the fire 
is currently being investigated. We believe we carry adequate insurance and do not expect that this event will have a material 
impact to our consolidated financial condition, results of operations or cash flows. Revenues from our operations at this facility 
represent less than 0.5% of our consolidated revenues.

10. Commitments and Contingencies (Continued)

 f.   Brooklyn Fire (Recall)

On January 31, 2015, a former Recall leased facility located in Brooklyn, New York was completely destroyed by a 
fire. Approximately 900,000 cartons of customer records were lost impacting approximately 1,200 customers. No one was 
injured as a result of the fire. We believe we carry adequate insurance to cover any losses resulting from the fire. There are three 
pending customer-related lawsuits stemming from the fire, which are being defended by our warehouse legal liability 
insurer. We have also received correspondence from other customers, under various theories of liability. We deny any liability 
with respect to the fire and we have referred these claims to our insurer for an appropriate response. We do not expect that this 
event will have a material impact on our consolidated financial condition, results of operations or cash flows.

g.   Roye Fire (Recall)

On January 28, 2002, a former leased Recall records management facility located in Roye, France was destroyed by a fire. 

Local French authorities conducted an investigation relating to the fire and issued a charge of criminal negligence for non-
compliance with security regulations against the Recall entity that leased the facility. We intend to defend this matter 
vigorously. We are currently corresponding with various customers impacted by the fire who are seeking payment under various 
theories of liability. There is also pending civil litigation with the owner of the destroyed facility, who is demanding payment 
for lost rental income and other items. Based on known and expected claims and our expectation of the ultimate outcome of 
those claims, we believe we carry adequate insurance coverage. We do not expect that this event will have a material impact on 
our consolidated financial condition, results of operations or cash flows.

h.   Puerto Rico Facility Damage

In September 2017, two of our four facilities in Puerto Rico, one owned and one leased, sustained damage as a result of 
Hurricane Maria. The leased facility experienced structural damage to a portion of the roof and wall, while the owned facility 
sustained non-structural damage to a portion of the roof. Both buildings sustained water damage that impacted certain customer 
records and we are in the process of fully assessing the extent of the damage to our customers’ records at these facilities. We 
believe we carry adequate insurance coverage for this event and do not believe it will have a material impact to our 
consolidated financial condition, results of operations or cash flows. Revenues from our operations in Puerto Rico represent less 
than 0.5% of our consolidated revenues.

_______________________________________________________________________________

Our policy related to business interruption insurance recoveries is to record gains within other (income) expense, net in 

our Consolidated Statements of Operations and proceeds received within cash flows from operating activities in our 
Consolidated Statements of Cash Flows. Such amounts are recorded in the period the cash is received. Our policy with respect 
to involuntary conversion of property, plant and equipment is to record any gain or loss within (gain) loss on disposal/write-
down of property, plant and equipment (excluding real estate), net within operating income in our Consolidated Statements of 
Operations and proceeds received within cash flows from investing activities within our Consolidated Statements of Cash 
Flows. Losses are recorded when incurred and gains are recorded in the period when the cash received exceeds the carrying 
value of the related property, plant and equipment.

11. Related Party Transactions

During the years ended December 31, 2015, 2016 and 2017, the Company had no related party transactions.

12. 401(k) Plans

We have a defined contribution plan, which generally covers all non-union United States employees meeting certain 
service requirements. Eligible employees may elect to defer from 1% to 25% of compensation per pay period up to the amount 
allowed by the Internal Revenue Code of 1986, as amended. In addition, IME operates a defined contribution plan, which is 
similar to our United States 401(k) Plan. We make matching contributions based on the amount of an employee's contribution in 
accordance with the plan documents. We have incurred expenses of $16,355, $24,407 and $21,192 for the years ended 
December 31, 2015, 2016 and 2017, respectively, associated with these plans.

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.

_______________________________________________________________________________

During the years ended December 31, 2015, 2016 and 2017, we declared distributions to our stockholders of $402,565, 
$502,863 and $603,743, respectively. These distributions represent approximately $1.91 per share, $2.04 per share and $2.27 
per share for the years ended December 31, 2015, 2016 and 2017, respectively, based on the weighted average number of 
common shares outstanding during each respective year.

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" for tax years beginning after 
2017), 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. For the years ended December 31, 2015, 2016 and 2017, the dividends we paid on our common 
shares were classified as follows:

Nonqualified ordinary dividends

13. Stockholders' Equity Matters (Continued)

The change in the percentage of our dividends that were characterized as a return of capital in 2015 and 2016 (11.6% and 

33.5%, respectively) compared to 2017 (0.0%) is primarily a result of the impact of the Deemed Repatriation Transition Tax 
associated with the Tax Reform Legislation that impacted the characterization of our 2017 dividends for United States federal 
income tax purposes. See Note 7 for further disclosure regarding the impact of the Deemed Repatriation Transition Tax on our 
2017 dividends. 

At The Market (ATM) Equity Program

In October 2017, we entered into a distribution agreement (the “Distribution Agreement”) with a syndicate of 10 banks 
(the “Agents”) pursuant to which we may sell, from time to time, up to an aggregate sales price of $500,000 of our common 
stock through the Agents (the “At The Market (ATM) Equity Program”). Sales of our common stock made pursuant to the 
Distribution Agreement may be made in negotiated transactions or transactions that are deemed to be “at the market” offerings 
as defined in Rule 415 under the Securities Act, including sales made directly on the NYSE, or sales made to or through a 
market maker other than on an exchange, or as otherwise agreed between the applicable Agent and us. We intend to use the net 
proceeds from sales of our common stock pursuant to the At The Market (ATM) Equity Program for general corporate 
purposes, including financing the expansion of our data center business and adjacent businesses through acquisitions, and 
repaying amounts outstanding from time to time under the Revolving Credit Facility.

During the quarter ended December 31, 2017 under the At The Market (ATM) Equity Program, we sold an aggregate of 

1,481,053 shares of common stock for gross proceeds of approximately $60,000, generating net proceeds of $59,100, after 
deducting commissions of $900. As of December 31, 2017, the remaining aggregate sale price of shares of our common stock 
available for distribution under the At The Market (ATM) Equity Program was approximately $440,000.

Equity Offering

On December 12, 2017, we entered into an underwriting agreement (the "Underwriting Agreement") with a syndicate of 

16 banks (the “Underwriters”) related to the public offering by us of 14,500,000 shares (the “Firm Shares”) of our common 
stock (the “Equity Offering”). The offering price to the public for the Equity Offering was $37.00 per share, and we agreed to 
pay the Underwriters an underwriting commission of $1.38195 per share. The net proceeds to us from the Equity Offering, after 
deducting underwriters' commissions, was $516,462.

Pursuant to the Underwriting Agreement, we granted the Underwriters a 30-day option to purchase from us up to an 

additional 2,175,000 shares of common stock (the “Option Shares”) at the public offering price, less the underwriting 
commission and less an amount per share equal to any dividends or distributions declared by us and payable on the Firm Shares 
but not payable on the Option Shares (the “Over-Allotment Option"). On January 10, 2018, the Underwriters exercised the 
Over-Allotment Option in its entirety. The net proceeds to us from the exercise of the Over-Allotment Option, after deducting 
underwriters' commissions, offering expenses and the per share value of the dividend we declared on our common stock on 
October 24, 2017 (for which the record date was December 15, 2017) which was paid on January 2, 2018, was approximately 
$76,200. The net proceeds of the Equity Offering and the Over-Allotment Option, together with the net proceeds from the 
issuance of the 51/4% Notes, were used to finance the purchase price of the IODC Transaction, which closed on January 10, 
2018, and to pay related fees and expenses. At December 31, 2017, the net proceeds of the Equity Offering, together with the 
net proceeds from the 51/4% Notes, were used to temporarily repay borrowings under our Revolving Credit Facility and invest 
in money market funds.

14. Divestitures

a.   Divestments Associated with the Recall Transaction

As disclosed in Note 6, in connection with the acquisition of Recall, we sought regulatory approval of the Recall 
Transaction from the DOJ, the ACCC, the CCB and the CMA and, as part of the regulatory approval process, we agreed to 
make the Divestments.

The assets and liabilities related to the Initial United States Divestments were sold to Access CIG in the Access Sale on 

May 4, 2016; the assets and liabilities related to the Australia Divestment Business were sold to the Australia Divestment 
Business Purchasers in the Australia Sale on October 31, 2016; the assets and liabilities related to the UK Divestments were 
sold to Oasis Group in the UK Sale on December 9, 2016; and the assets and liabilities associated with the Seattle/Atlanta 
Divestments and the Canadian Divestments were sold to ARKIVE in the ARKIVE Sale on December 29, 2016.

We have concluded that the Australia Divestment Business and the Iron Mountain Canadian Divestments (collectively, the 
“Iron Mountain Divestments”) do not meet the criteria to be reported as discontinued operations in our Consolidated Statements 
of Operations and Consolidated Statements of Cash Flows for the years ended December 31, 2015 and 2016, respectively, as 
our decision to divest these businesses 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 the Iron Mountain Divestments are presented as a 
component of income (loss) from continuing operations in our Consolidated Statements of Operations for the years ended 
December 31, 2015 and 2016 and the cash flows associated with these businesses are presented as a component of cash flows 
from continuing operations in our Consolidated Statements of Cash Flows for the years ended December 31, 2015 and 2016 
through the closing date of the Australia Sale, in the case of the Australia Divestment Business, and through the closing date of 
the ARKIVE Sale, in the case of the Iron Mountain Canadian Divestments. 

During the year ended December 31, 2016, we recorded charges of $15,417 and $1,421 to other expense, net associated 

with the loss on disposal of the Australia Divestment Business and the Iron Mountain Canadian Divestments, respectively, 
representing the excess of the carrying value of these businesses compared to their fair value (less costs to sell).

We have concluded that the Initial United States Divestments, the Seattle/Atlanta Divestments, the Recall Canadian 
Divestments and the UK Divestments (collectively, the “Recall Divestments”) meet the criteria to be reported as discontinued 
operations in our Consolidated Statements of Operations and Consolidated Statements of Cash Flows for the years ended 
December 31, 2016 and 2017, as the Recall Divestments met the criteria to be reported as assets and liabilities held for sale at, 
or within a short period of time following, the closing of the Recall Transaction. 

The table below summarizes certain results of operations of the Recall Divestments included in discontinued operations 

for the years ended December 31, 2016 and 2017:

(1)  The Access Sale occurred nearly simultaneously with the closing of the Recall Transaction. Accordingly, the revenue 
and expenses associated with the Initial United States Divestments are not included in our Consolidated Statement of 
Operations for the year ended December 31, 2016  and the cash flows associated with the Initial United States 
Divestments are not included in our Consolidated Statement of Cash Flows for the year ended December 31, 2016, due 
to the immaterial nature of the revenues, expenses and cash flows related to the Initial United States Divestments for 
the period of time we owned these businesses (May 2, 2016 through May 4, 2016). 

The assets subject to the Recall Divestments were acquired in the Recall Transaction and, therefore, the fair value of the 

Recall Divestments has been reflected in the allocation of the purchase price for Recall as a component of "Fair Value of Recall 
Divestments". See Note 6.

 b. Russia and Ukraine Divestment

On May 30, 2017, IM EES, a consolidated subsidiary of IMI, sold its records and information management operations in 
Russia and Ukraine to OSG Records Management (Europe) Limited (“OSG”) in a stock transaction (the “Russia and Ukraine 
Divestment”). As consideration for the Russia and Ukraine Divestment, IM EES received a 25% equity interest in OSG (the 
“OSG Investment”).

We have concluded that the Russia and Ukraine Divestment does not meet the criteria to be reported as discontinued 
operations in our consolidated financial statements, as our decision to divest these businesses 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 
these businesses are presented as a component of income (loss) from continuing operations in our Consolidated Statements of 
Operations for the years ended December 31, 2015, 2016 and 2017 and the cash flows associated with these businesses are 
presented as a component of cash flows from continuing operations in our Consolidated Statements of Cash Flows for years 
ended December 31, 2015, 2016 and 2017 through the sale date. 

As a result of the Russia and Ukraine Divestment, we recorded a gain on sale of $38,869 to other expense (income), net, 
in the second quarter of 2017, representing the excess of the fair value of the consideration received over the carrying value of 
our businesses in Russia and Ukraine. As of the closing date of the Russia and Ukraine Divestment, the fair value of the OSG 
Investment was approximately $18,000. As of the closing date of the Russia and Ukraine Divestment, the carrying value of our 
businesses in Russia and Ukraine was a credit balance of $20,869, which consisted of (i) a credit balance of approximately 
$29,100 of cumulative translation adjustment associated with our businesses in Russia and Ukraine that was reclassified from 
accumulated other comprehensive items, net, (ii) the carrying value of the net assets of our businesses in Russia and Ukraine, 
excluding goodwill, of $4,716 and (iii) $3,515 of goodwill associated with our Northern and Eastern Europe reporting unit (of 
which our businesses in Russia and Ukraine were a component of prior to the Russia and Ukraine Divestment), which was 
allocated, on a relative fair value basis, to our businesses in Russia and Ukraine. 

We account for the OSG Investment as an equity method investment. As of December 31, 2017, the fair value of the OSG 

Investment is $17,539 and is presented as a component of Other within Other assets, net in our Consolidated Balance Sheet.

15. Cost Optimization Plans

Transformation Initiative

During the third quarter of 2015, we implemented a plan that calls for certain organizational realignments to reduce our 

overhead costs, particularly in our developed markets, in order to optimize our selling, general and administrative cost structure 
and to support investments to advance our growth strategy (the “Transformation Initiative”). As a result of the Transformation 
Initiative, we recorded charges of $10,167, $6,007 and $500 for the years ended December 31, 2015, 2016 and 2017, 
respectively, primarily related to employee severance and associated benefits. Costs included in the accompanying

SCHEDULE III—SCHEDULE OF REAL ESTATE AND ACCUMULATED DEPRECIATION
DECEMBER 31, 2017
(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 1,131 leased 
facilities in our real estate portfolio. In addition, Schedule III does not include any value for capital 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.f. to Notes to Consolidated Financial Statements as of December 31, 2017:

CAUTIONARY NOTE REGARDING
FORWARD-LOOKING STATEMENTS

The stockholder letter contains certain  forward-looking statements
within the meaning of the Private Securities Litigation Reform Act
of 1995 and other securities laws and is subject to the safe-harbor
created by such Act. Forward-looking  statements include our
financial performance outlook and statements  regarding our
operations, economic performance, financial condition, goals, beliefs,
future growth strategies, investment objectives,  plans and current
expectations, such as expected growth  due to shift  in revenue mix,
projected revenues from our emerging market acquisition  pipeline
and acquisitions and valuation creation and returns associated  with
our data center business. These forward-looking statements are
subject to various known and unknown risks,  uncertainties  and other
factors. When we use words such as ‘‘believes,’’ ‘‘expects,’’
‘‘anticipates,’’ ‘‘estimates’’ or similar expressions, we are making
forward-looking statements. You should  not  rely upon forward-
looking statements except as statements  of our present intentions
and of our present expectations, which may or may  not  occur.
Although we believe that our forward-looking statements are based
on reasonable assumptions, our expected results may not be
achieved, and actual results may differ materially from our
expectations. In addition, important factors that could cause actual
results to differ from our other expectations include, among others:
(i) our ability to remain qualified for taxation as  a real estate
investment trust for U.S. federal income tax purposes; (ii)  the
adoption of alternative technologies and shifts by our customers to
storage of data through non-paper based  technologies;  (iii) changes
in customer preferences and demand for our storage and
information management services; (iv)  the  cost to comply with
current and future laws, regulations and customer demands relating
to privacy issues, as well as fire and safety standards; (v) the impact
of litigation or disputes that may arise  in connection  with incidents
in which we fail to protect our customers’ information; (vi) changes
in the price for our storage and information management services
relative to the cost of providing such storage  and information
management services; (vii) changes in the  political and economic
environments in the countries in which our international subsidiaries
operate and changes in the political climate; (viii) our ability or
inability to manage growth, expand internationally, complete
acquisitions on satisfactory terms and to integrate acquired
companies efficiently; (ix) changes in the amount of our  growth and
maintenance capital expenditures; (x) our ability to comply with our
existing debt obligations and restrictions in  our debt instruments or
to obtain additional financing to meet our working capital needs;
(xi) the impact of service interruptions or equipment damage and
the cost of power in our data center  operations (xii) changes  in the
cost of our debt; (xiii) the impact of alternative, more attractive
investments on dividends; (xiv) the cost or potential liabilities
associated with real estate necessary for our business; (xv) the
performance of business partners upon whom  we depend for
technical assistance or management expertise outside the United
States; (xvi) other trends in competitive or  economic conditions
affecting our financial condition or results of operations not
presently contemplated; and (xvii) other risks described more  fully in
our Annual Report on Form 10-K filed with  the Securities and
Exchange Commission, or SEC, on February 16, 2018 under
‘‘Item 1A. Risk Factors’’ and other documents that we file with the
SEC from time to time. Except as required by  law, we undertake  no
obligation to release publicly the result of any revision to these
forward-looking statements that may  be made  to  reflect events or
circumstances after the date hereof or to reflect the occurrence of
unanticipated events.
