BUSINESS STRATEGY
OVERVIEW
Our financial modelcompany has been a market leader in the physical ecosystem supporting information storage and retrieval, as most businesses have relied on paper documents or computer tapes to store their valuable information. Over time, customers are increasing their digital information, with the new information storage ecosystem being a hybrid of physical and digital mediums. We are a different company than the one we have been historically. The strategic journey we are on is baseddriving this change and our focus remains on the recurring naturethree pillars outlined below to grow our business.
Continued growth in physical storage through revenue management as well as volume growth achieved in faster growing emerging markets and consumer and adjacent business growth in developed markets
We are establishing and enhancing leadership positions in higher-growth markets such as central and eastern Europe, Latin America, Asia and Africa, through both organic expansion and acquisitions in countries where GDP growth is faster and outsourcing information management is at an earlier stage.
We continue to identify, acquire, incubate and scale complementary businesses and products to support our long-term growth objectives and drive solid returns on invested capital. These opportunities include our digital services and our Entertainment Services, Fine Arts and Consumer Storage (each as defined below) businesses.
Utilizing our global scale as well as 70 years of customer trust to deliver differentiated data center offerings
We have made significant progress in scaling our Global Data Center Business through acquisitions and organic growth, with 15 operating data centers across 13 global markets.
As of December 31, 2020, approximately 87% of our data center capacity was leased. With total potential capacity of 376 megawatts ("MW") in land and buildings currently owned or operated by us, we are among the largest global data center operators.
Developing and offering new products and services that allow our customers to achieve reliable and secure information management solutions in an increasingly hybrid physical and digital world
Our customers are faced with navigating a more complex regulatory environment, and one in which hybrid physical and digital solutions have become the norm. Our strategy is underpinned by our persistent focus on best-in-class customer experience, as we continue to seek innovative solutions to help our customers progress on their journey from physical storage to a digital ecosystem.

Part I
PROJECT SUMMIT
In October 2019, we announced our global program ("Project Summit") designed to better position us for future growth and achievement of our storage rental revenuesstrategic objectives. We expanded Project Summit during the first quarter of 2020 to include additional opportunities to streamline our business 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.

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,operations, as well as increased volumes from existing customers. We also expectaccelerated the timing of certain opportunities previously identified. Such opportunities include leveraging new technology solutions 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 allowsenable us to strengthenmodernize 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 coveragedelivery 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 acquisitionsefficiently utilize our fleet, labor and investments in our emerging markets will focus primarilyreal estate. For further details on expanding priority markets in centralProject Summit, see the "Overview" section of “Item 7. Management’s Discussion and eastern Europe, Latin AmericaAnalysis of Financial Condition and Asia.

The experience, depth and strengthResults 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 includedOperations” 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 acquisitionsReport.

Table 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.Contents
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”). Part I
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.

BUSINESS SEGMENTS
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.

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.

Part I
Our Business Fundamentals
BUSINESS ATTRIBUTES
Our business fundamentals are based onhas 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:following attributes:
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%.

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 growthprimarily 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.

Maintenance: Non-real estate assets necessary to maintain ongoing business operations primarily related to the repair or replacement of customer-facing assets such as containers and shred bins, warehouse equipment, fixtures, computer hardware, or third-party or internally-developed software assets. This category also includes capital to support initiatives such as sales and marketing and IT projects to support infrastructure requirements, or Non-Real Estate Maintenance.
Data Center Investment and Maintenance:
Defined as capital expenditures that support data center business growth, primarily related to investments in new construction of data center facilities (including the acquisition of land and development of facilities) or capacity expansion in existing buildings, as well as capital expenditures that are expected to support incremental improvements to our data center business, through either increasing revenue, improving operating efficiency, or extending the useful life of our real estate operating assets. This also includes capital expenditures necessary to maintain ongoing business operations primarily related to the repair or maintenance of assets, as well as for the re-configuration of existing assets.
Innovation and Growth Investment:
Defined as discretionary capital expenditures in significant new products and services in new, existing or adjacent business opportunities.

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. COMPETITION
We compete with our current and potential customers' internal storage and information management services capabilities. We compete with numerousthousands of storage and information management services providers in every geographic area where we operate. The physicalaround the world as well as storage and information management services industry is highly competitivemanaged and includes thousands of competitors in North America and around the world.operated internally by organizations. We believe that competition for records and information customers is based on price, reputation and reliability, quality and security of storage, quality of service and scope and scale of technology, andtechnology. While the majority of our competitors operate in only one market or region, we believe we generally competeprovide a differentiated global offering that competes effectively in these areas.
We also compete with numerous data center developers, owners and operators, many of whom own properties similar to ours in some of the same metropolitan areas where our facilities are located. We believe that competition for data center customers is based on availableavailability of power, security considerations, location, connectivity and rental rates, and we generally believe we generally compete effectively in each of these areas. Additionally, we believe our strong brand, global footprint and excellent commercial relationships enable us to compete successfully and provide significant cross-sell opportunities with our existing customer base.
Alternative TechnologiesHUMAN CAPITAL MANAGEMENT
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.

INCLUSION AND DIVERSITY
We believe that an inclusive environment with diverse teams produces more creative solutions, results in better, more innovative products and services and is crucial to our efforts to attract and retain key talent. We have prioritized inclusion and diversity ("I&D") as part of our corporate-wide strategic goals. Strategies we have taken to create and sustain a more inclusive and diverse environment include: appointing senior leadership for I&D efforts; ensuring that our recruiting efforts reflect our diversity goals; and launching, expanding and supporting our Employee Resource Groups—groups of our employees that voluntarily join together based on shared characteristics, life experiences, or interest around particular activities.
COMPANY CULTURE
We recognize that a great culture is foundational to how we deliver on our purpose and strategy and create sustained growth and value for our shareholders. We have committed significant resources to building a sustainable culture that enables innovation and creativity and facilitates trust, employee engagement, belonging and better performance. We understand the importance of listening to our employees, and, to that end, we regularly survey our employees to obtain their views and assess their experience. We use the views expressed in the surveys to adjust our approach on culture and driving employee engagement. We also use employee survey information, headcount data and cost analyses to gain insights into how and where we work.
COMMUNITY INVOLVEMENT
We are currently under renewed labor agreements or operating under an extension agreement.committed to integrating responsible and sustainable practices throughout our organization to help our operations to have a positive impact on the environment and the communities in which we operate. We aim to give back to the communities where we live and work, and believe that this commitment helps in our efforts to attract and retain employees. We offer philanthropic support to our global community through our Living Legacy Initiative, which is our commitment to help preserve and make accessible cultural and historical information and artifacts. We encourage volunteerism in the communities in which we live and work through our Moving Mountains volunteer program, offering paid time off for employees to help community-based and civic-minded organizations.
Insurance and Contractual Limitations on LiabilityINSURANCE
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'workers’ compensation, general liability, umbrella, automobile, professional, warehouse legal liability and directors'directors’ and officers'officers’ liability policies.
Our customer contracts typically contain provisions limitingGOVERNMENT REGULATION
We are required to comply with numerous U.S. federal, state, and foreign laws and regulations covering a wide variety of subject matters which may have a material effect on our 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,capital expenditures, earnings 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,competitive position.
For example, 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.acquired. We therefore may be potentially liable for environmental cost and may be unable to sell, rent, mortgage or use contaminated real estate owned or leased by us. Under various federal, state and local environmental laws, we may be liable for environmental compliance and remediation costs to address contamination, if any, located at owned and leased properties as well as damages arising from such contamination, whether or not we know of, or were responsible for, the contamination, or the contamination occurred while we owned or leased the property. Environmental conditions for which we might be liable may also exist at properties that we may acquire in the future. In addition, future regulatory action and environmental laws may impose costs for environmental compliance that do not exist today.
We transfer a portion of our risk of financial loss due to currently undetected environmental matters by purchasing an environmental impairment liability insurance policy, which covers all owned and leased locations. Coverage is provided for both liability and remediation costs.

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

ITEM 1A. Risk Factors.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“Cautionary Note Regarding Forward-Looking Statements"Statements” before deciding to invest in our securities.
Operational RisksBUSINESS 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. AlternativeStorage volume and/or demand for our traditional storage related services may decline as our customers adopt alternative storage technologies, exist, many of which require significantly less space than traditional physical records and tapes,tape storage. Our customers’ shift from paper and astape storage to alternative technologies are adopted, storage related services may declineaccelerate as a result of the paper documents or tapesCOVID-19 pandemic. While volumes in our Global RIM Business segment were relatively steady in 2020 and we store become less active and more archival. Weexpect them to remain relatively consistent in the near term, we can provide no assurance that our customers will continue to store most or a portion of their records as paper documents or as tapes, or that the paper documents or tapes they do store with us will require our storage related services at the same levels as they have in the past. A significant shift by our customers to storage of data through non-paper or tape-basednon-tape-based technologies, whether now existing or developed in the future, could adversely affect our businesses. In addition, the digitization of records may shift our revenue mix from the more predictable storage revenue to service revenue, which is inherently more volatile.
The COVID-19 pandemic and its resulting economic impact may materially adversely affect our business, operations, financial results and liquidity.
In March 2020, the World Health Organization declared a novel strain of coronavirus (“COVID-19”) a pandemic. This resulted in U.S. federal, state and local and foreign governments and private entities mandating various restrictions, including travel restrictions, restrictions on public gatherings and stay-at-home orders and advisories. In response, we temporarily closed certain of our offices and facilities across the world, implemented certain travel restrictions for our employees and transitioned many of our employees to remote working arrangements, with some of our operations being run with limited personnel on site. In addition, many of our customers have implemented stay-at-home measures and other restrictions that reduce the demand for our routine services. The preventative and protective actions that governments have ordered, or we or our customers have implemented, have resulted in a period of reduced service operations and business disruption for us, our customers and other third parties with which we do business.
The COVID-19 pandemic has also had a substantial adverse impact on the global economy. While we do not currently believe that the implications of the COVID-19 pandemic have had a material adverse impact on our ability to collect our accounts receivable, global economic conditions related to the COVID-19 pandemic may have a material adverse effect on our customers, which could impact our future ability to collect our accounts receivable. In addition, if the COVID-19 pandemic and resulting recessionary conditions continue to disrupt the credit and financial markets or impact our credit ratings, our ability to access capital on favorable terms, if at all, could be adversely affected, which could have an adverse effect on our liquidity needs.
Due to the unpredictable and rapidly changing nature of the COVID-19 pandemic and the resulting economic distress, the extent to which it continues to impact us will depend on numerous factors that we are currently unable to predict, including: the duration and severity of the COVID-19 pandemic; the development, distribution and efficacy of any COVID-19 vaccines; the duration or re-emergence of outbreaks; the continuation, resumption, and/or expansion of restrictions imposed by governments and businesses; the impact of the pandemic on economic activity and any resulting recessionary conditions, and the strength and duration of any economic recovery; the health of our workforce; our ability to meet staffing needs for critical functions; and the impact on our customers, suppliers, vendors, and other business partners, and their respective financial condition. Furthermore, when the COVID-19 pandemic has ended, our ability to resume normal business operations may be delayed, and actions we have taken to manage costs may make it more challenging to meet any increased customer demand following the pandemic.
Failure to execute our strategic growth plan may adversely impact our financial condition and results of operations.
As part of our strategic growth plan, we expect to invest in our existing businesses, including records and information management storage and services businesses in our higher-growth markets, data centers and adjacent businesses, and in new businesses, business strategies, products, services, technologies and geographies, and we may selectively divest certain businesses. These initiatives may involve significant risks and uncertainties, including:
our inability to execute on our plan to incorporate the digitization of our customers’ records and new digital information technologies into our offerings;
failure to achieve satisfactory returns on new product offerings, acquired companies, joint ventures, growth initiatives, or other investments, particularly in markets where we do not currently operate or have a substantial presence;
our inability to identify suitable companies to acquire, invest in or partner with;
our inability to complete acquisitions or investments on satisfactory terms;
our inability to structure acquisitions or investments in a manner that complies with our debt covenants and is consistent with our leverage ratio goals;
8IRON MOUNTAIN 2020 FORM 10-K

Part I
increased demands on our management, operating systems, internal controls and financial and physical resources and, if necessary, our inability to successfully expand our infrastructure;
incurring additional debt necessary to acquire suitable companies or make other growth investments if we are unable to pay the purchase price or make the investment out of working capital or the issuance of our common stock or other equity securities;
our inability to manage the budgeting, forecasting and other process control issues presented by future growth, particularly with respect to operations in countries outside of the United States or in new lines of business;
insufficient revenues to offset expenses and liabilities associated with new investments; and
our inability to attract, develop and retain skilled employees to lead and support our strategic growth plan, particularly in new businesses, technologies, products or offerings outside our core competencies.
Our data center expansion in particular requires significant capital commitments. Our data center expansion and other new ventures are inherently risky and we can provide no assurance that such strategies and offerings will be successful in achieving the desired returns within a reasonable timeframe, if at all, and that they will not adversely affect our business, reputation, financial condition, and operating results.
We face competition from other companies, some of which possess substantial resources, in our efforts to grow our data center, international and complementary businesses. As a result, we may be unable to acquire or invest in, or we may pay a premium purchase price for, data centers, technology and higher-growth markets and adjacent businesses that support our strategic growth plan, which could have an adverse effect on our results of operations and financial condition. The foregoing risks may be exacerbated as a result of the COVID-19 pandemic.
As stored records and tapes become less active our service revenue growth and profitability from related services may decline.
Our records managementRecords Management and data protectionData Management service revenue growth is being negatively impacted by declining activity rates as stored records and tapes are becoming less active.active and more archival, and these activity levels were further negatively impacted by the COVID-19 pandemic. The amount of information available to customers through the Internetdigitally or in 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.
Our program to simplify our global structure may not be successful.
In October 2019, we announced Project Summit, a global program designed to better position us for future growth and achievement of our strategic objectives. Project Summit focuses on simplifying our global records and information management structure, streamlining our managerial structure and leveraging our global and regional customer facing resources. We also plan to implement systems and process changes designed to make our organization more agile and dynamic, streamline our organization and reallocate our resources to better align with our strategic goals. We expect the total program benefits associated with Project Summit, which we have expanded since our initial announcement, to be fully realized exiting 2021. However, we may not be able to realize the full amount of our expected improvements to Adjusted EBITDA in a timely manner, or at all, and the costs associated with Project Summit may exceed our expectations. In addition, this program may yield unintended consequences, such as attrition beyond our intended reduction in force, distraction of our employees and our anticipated systems and process changes may not work as expected and may create additional risks to our business. As a result, Project Summit could have a material adverse effect on our results of operations or financial condition.
Our future growth depends in part upon our ability to continue to effectively manage and execute on revenue management.
Over the past several years, our organic revenue growth has been positively impacted by our ability to effectively introduce, expand and monitor revenue management initially in our more established markets, and subsequently in our higher-growth markets. If we are not able to continue and effectively manage pricing, our results of operations could be adversely affected and we may not be able to execute on our strategic growth plan.
Changes in customer behavior with respect to document destruction and pricingof records stored with us could adversely affect our business, financial condition and results of operations.operations.

We and customer focus onour customers are subject to laws and governmental regulations relating to data securityprivacy and cybersecurity and our customers’ demands in this area are increasing. This may cause us to incur significant expenses and non-compliance with such regulations and demands could 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 businessesbusiness.
We are subject to numerous U.S. federal, state, local 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 federalforeign laws and regulations affecting financial institutions, health care providers and plans and others impose requirements regarding therelating to data privacy and securitycybersecurity. These regulations are complex, change frequently and have tended to become more stringent over time. There are also a number of information maintained by those institutions as well aslegislative proposals pending before the U.S. Congress, various state legislative bodies and foreign governments concerning data protection that could affect us. In addition, a growing number of U.S. and foreign legislative and regulatory bodies have adopted consumer notification to persons whose personaland other requirements if consumer information is accessed by an unauthorized third party. Somepersons and additional regulations regarding the use, access, accuracy and security of thesesuch information are possible. In the U.S., we are subject to various state laws and regulationswhich 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 breachdisparate notification requirement beyond the financial and medical fields.

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.regimes. In Europe, Regulation (EU) 2016/679 (commonly referred toaddition, 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 membersa result 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 leadinstances in which personal information has been compromised, our customers to requestare requesting that we take additionalincreasingly sophisticated measures to enhance security store electronicand comply with data locally,privacy regulations, and that we assume higher liability under our contracts.
We devote substantial resources, and may in the future have to devote significant additional resources, to facilitate compliance with laws and regulations, our customers’ data privacy and security demands, and to investigate, defend or remedy actual or alleged violations or breaches. Any failure by us to comply with, or remedy any violations or breaches of, laws and regulations or customer requirements could result in the curtailment of certain of our operations, the imposition of fines and penalties, liability resulting from litigation, restrictions on our ability to carry on or expand our operations, significant costs and expenses and reputational harm. For example, we have experienced incidents in which customers' backup tapes or other records havecustomers’ information has 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 resultIt is difficult to predict the impact on our business if we were subject to allegations 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 operationshaving violated existing laws 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.regulations.

Moreover, our ability to integrateuntil we have migrated businesses we acquire onto our IT systems, we may challenge our ability to prevent such security breaches.face additional risks because of the continued use of predecessor IT systems. We have outsourced, 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. In addition, the continuation of remote work arrangements or operating with limited personnel as a result of the COVID-19 pandemic could increase our cybersecurity risks. A successful breach of the security of our IT systems could lead to theft or misuse of our customers'customers’ proprietary or confidential information and result in third party claims against us and reputational harm.

As of December 31, 2017,2020, we operated 1,316 records management, off-site data protection, data center and fine art storageapproximately 1,450 facilities worldwide, including 627more than 600 in the United States. Many of these facilities were built and outfitted by third parties and added to our real estate portfolio as part of acquisitions. Some of these facilities contain fire suppression and safety features that are different from our current specifications and current standards for new facilities, although we believe all of our facilities were constructed, in all material respects, in compliance with applicable 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 businessacquire 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.

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

Furthermore, changes in environmental laws in any jurisdiction in which we operate could increase compliance costs or impose limitations on our operations. For example, our emergency generators at our data centers are subject to regulations and permit requirements governing air pollutants, and the heating, ventilation and air conditioning and fire suppression systems at some of our data centers and data management locations may include ozone-depleting substances that are subject to regulation. While environmental regulations do not normally impose material costs upon operations at our facilities, unexpected events, equipment malfunctions, human error and changes in law or regulations, among other factors, could result in unexpected costs, which could be material.
Failure to successfully integrate acquired businesses could negatively impact our balance sheet and results of operations.
Strategic acquisitions are an important element of our growth strategy and the success of any acquisition we make depends in part on our ability to integrate the acquired business and realize anticipated synergies. The process of integrating acquired businesses, particularly in new markets, may involve unforeseen difficulties and may require a disproportionate amount of our management’s attention and our financial and other resources.
For example, the success of our significant acquisitions depends, in large part, on our ability to realize the anticipated benefits, including cost savings from combining the acquired businesses with ours. To realize these anticipated benefits, we must be able to successfully integrate our business and the acquired businesses, and this integration is complex and time-consuming. We may encounter challenges in the integration process including the following:
challenges and difficulties associated with managing our larger, more complex, company;
conforming standards, controls, procedures and policies, business cultures and compensation and benefits structures between the two businesses;
consolidating corporate and administrative infrastructures;
coordinating geographically dispersed organizations;
potential unknown liabilities and unforeseen expenses or delays associated with an acquisition; and
our ability to deliver on our strategy going forward.
Further, our acquisitions subject us to liabilities (including tax liabilities) that may exist at an acquired company, some of which may be unknown. Although we and our advisors conduct due diligence on the 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.
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,digital solutions, data center, Destructiondestruction 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 related 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 digital solutions and 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 orderor with high enough coverage amounts to cover losses to us in connection with customer contract disputes.

International operations may pose unique risks.
As of December 31, 2017,2020, we provided storage and information management servicesoperated in 5255 countries outside the United States. Our international operations account for a significant portion of our overall operations, and as part of our growth strategy, we expect its share to increase as we continue to acquire or invest in 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 anticorruptionanti-corruption laws, such as the Foreign Corrupt Practices Act and the United Kingdom Bribery Act, and, although we have implemented internal controls, policies and procedures and training to deter prohibited practices, our employees, partners, contractors or agents may violate or circumvent such policies and the law;
the volatility of certain foreign economies in which we operate;
political uncertainties and changes in the global political climate or other global events, such as the recent trade wars involving the U.S. or global pandemics, which may impose restrictions on, or create additional risk in relation to, global operations;operations, which risks may become more pronounced as we consolidate operations across countries and need to move records and data across borders;
unforeseen liabilities, particularly within acquired businesses;
costs and difficulties associated with managing international operations of varying sizes and scale;scale, including operations involving cross-border service offerings;
our operations in the United Kingdom and the European Union may be adversely affected by the exit from the European Union (Brexit) by the United Kingdom, and the associated uncertainty;
the risk that business partners upon whom we depend for technical assistance or management and acquisition expertise in some markets outside of the United States will not perform as expected;
difficulties attracting and retaining local management and key employees to operate our business in certain countries; and
cultural differences and differences in business practices and operating standards;standards, as well as risks and challenges in expanding into countries where we have no prior operational experience.
foreign currency fluctuations.Our use of joint ventures could expose us to additional risks and liabilities, including our reliance on joint venture partners that may have economic and business interests that are inconsistent with our business interests, our lack of sole decision-making authority, and disputes between us and our joint venture partners.
As part of our growth strategy, particularly in connection with our international and data center expansion, we currently, and may in the future, co-invest with third parties using joint ventures. These joint ventures can result in our holding non-controlling interests in, or having shared responsibility for managing the affairs of, a property or portfolio of properties, business, partnership, joint venture or other entity. As a result, in connection with our pursuit or entrance into any such joint venture, we may be subject to additional risks, including:
our ability to sell our interests in the joint venture may be limited by the joint venture agreement;
our ability to grow our storage volume when we rely on non-controlling interests in joint ventures for this growth;
we may not have the right to exercise sole decision-making authority regarding the properties, business, partnership, joint venture or other entity;
if our partners become bankrupt or fail to fund their share of required capital contributions, we may choose or be required to contribute such capital;
our partners may have economic, tax or other interests or goals that are inconsistent with our interests or goals, and that could affect our ability to negotiate satisfactory joint venture terms, to operate the property or business or maintain our qualification for taxation as a REIT;
our partners may be subject to different laws or regulations than us, or may be structured differently than us for tax purposes, which could create conflicts of interest and/or affect our ability to maintain our qualification for taxation as a REIT;
our partners may take actions that are not within our control, which could require us to dispose of the joint venture asset, transfer it to a taxable REIT subsidiary (“TRS”) in order for us to maintain our qualification for taxation as a REIT, or purchase such partner’s interests or assets at an above-market price;
we may agree to restrictions on our ability to expand our business in certain geographies independently or with other partners;
disputes between us and our partners may result in litigation or arbitration that would increase our expenses and prevent our management from focusing their time and effort on our day-to-day business; and
we may in certain circumstances be liable for the actions of our third-party partners or guarantee all or a portion of the joint venture’s liabilities, which may require us to pay an amount greater than our investment in the joint venture.
Each of these factors may result in returns on these investments being less than we expect or in losses, and our financial and operating results may be adversely affected.

Significant costs or disruptions at our data centers could adversely affect our business, financial condition and results of operations.
Since 2017, we have substantially expanded our Global Data Center Business and we expect to continue to grow our Global Data Center Business. For example, we paid an aggregate cash purchase price of over $1.7 billion for data center businesses we acquired in 2017 and 2018 and incurred other costs associated with the development of real estate to support this business. Our Global Data Center Business depends on providing customers with highly reliable facilities, power infrastructure and operations solutions, and we will need to retain and hire qualified personnel to manage our data centers. Service interruptions or significant equipment damage could result in difficulty maintaining service level commitment obligations that we owe to certain of our customers. Service interruptions or equipment damage may occur at one or more of our data centers because of numerous factors, including: human error; equipment failure; physical, electronic and cyber security breaches; fire, hurricane, flood, earthquake and other natural disasters; water damage; fiber cuts; extreme temperatures; power loss or telecommunications failure; war, terrorism and any related conflicts or similar events worldwide; and sabotage and vandalism. We also purchase significant amounts of electricity from generating facilities and utility companies that are subject to environmental laws, regulations and permit requirements. These environmental requirements are subject to material change, which could result in increases in our electricity suppliers’ compliance costs that may be passed through to us. In particular,addition, climate change may increase the likelihood that our net income, debt balancesdata centers are affected by some of these factors.
While these risks could impact our overall business, they could have a more significant impact on our Global Data Center Business, where we have service level commitment obligations to certain of our customers. As a result, service interruptions or leveragesignificant equipment damage at our data centers could result in difficulty maintaining service level commitments to these customers and potential claims related to such failures. Because our data centers are critical to many of our customers’ businesses, service interruptions or significant equipment damage at our data centers could also result in lost profits or other indirect or consequential damages to our customers.
Our Global Data Center Business is susceptible to regional costs of power, power shortages, planned or unplanned power outages and limitations on the availability of adequate power resources. We rely on third parties to provide power to our data centers. We are therefore subject to an inherent risk that such third parties may fail to deliver such power in adequate quantities or on a consistent basis. If the power delivered to our data centers is insufficient or interrupted, we would be required to provide power through the operation of our on-site generators, generally at a significantly higher operating cost. Additionally, global fluctuations in the price of power can increase the cost of energy, and we may be limited in our ability to, or may not always choose to, pass these increased costs on to our customers. We also rely on third party telecommunications carriers to provide internet connectivity to our customers. These carriers may elect not to offer or to restrict their services within our data centers or may elect to discontinue such services. Furthermore, carriers may face business difficulties, which could affect their ability to provide telecommunications services or the quality of such services. If connectivity is interrupted or terminated, our financial condition and results of operations may be adversely affected. Events such as these may also impact our reputation as a data center provider which could adversely affect our results of operations.
Our data center expansion requires a significant amount of capital and, if we are not able to raise that capital on advantageous terms, our ability to fund our data center expansion may be limited.
Our data center expansion requires significant capital commitments. In addition, we may be required to commit significant operational and financial resources in connection with the organic growth of our Global Data Center Business, generally 12 to 18 months in advance of securing customer contracts, and we may not have enough customer demand to support these data centers when they are built. There can be significantlyno assurance we will have sufficient customer demand to support these data centers or data centers we have acquired or that we will not be adversely affected by fluctuations in currencies.

the risks noted above, which could make it difficult for us to realize expected returns on our investments, if any.
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.fluctuations. 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.position and reputation.
Having the United States Government as a customer subjects us to certain regulatory and contractual requirements. Failure to comply with these requirements could subject us to investigations, price reductions, up to treble damages, and civil penalties. Noncompliance with certain regulatory and contractual requirements could also result in us being suspended or barreddebarred from future United States Government contracting. We may also face private derivative securities claims as a resultbecause 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, hurricanes and earthquakes, or any coverage for certain losses, such as losses from riots or terrorist activities;
inability to use our real estate holdings effectively and costs associated with vacating or consolidating facilities if the demand for physical storage were to diminish; and
liability under environmental laws for the costs of investigation and cleanup of contaminated real estate owned or leased by us, whether or not (i) we know of, or were responsible for, the contamination, or (ii) the contamination occurred while we owned or leased the property.

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

Unexpected events, including those resulting from climate change, could disrupt our operations and adversely affect our reputation and results of operations.
Unexpected events, including fires or explosions at our facilities, war or terrorist activities, natural disasters such as hurricanesearthquakes and earthquakes, war or terrorist activities,wildfires, unplanned power outages, supply disruptions, and failure of equipment or systems, and severe weather events, such as droughts, heat waves, hurricanes, and flooding, could adversely affect our reputation and results of operations.operations through physical damage to our facilities and equipment and through physical damage to, or disruption of, local infrastructure. During the past several years we have seen an increase in the frequency and intensity of severe weather events and we expect this trend to continue due to climate change. Some of our key facilities worldwide are vulnerable to severe weather events, and global weather pattern changes may also pose long-term risks of physical impacts to our business. Our customers rely on us to securely store and timely retrieve their critical information, and, while we maintain disaster recovery and business continuity plans that would be implemented these situations, these unexpected events could result in customer service disruption, physical damage to one or more key operating facilities and the information stored in those facilities, the temporary closure of one or more key operating facilities or the temporary disruption of information systems, each of which could negatively impact our reputation and results of operations. During the past several years we have seen an increase in severe weatherIn addition, these unexpected 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 incidentsevents 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 costslitigation 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 providingif 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 atotherwise perceive our data centers, unexpected events, equipment malfunctions, human error and changes in law or regulations, among other factors, could result in unexpected costs dueresponse to violation of environmental laws, required permits or additional operation limitations or costs.

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.adequate.
Fluctuations in commodity prices may affect our operating revenues and results of operations.
Our operating revenues and results of operations are impacted by significant changes in commodity prices. In particular, our secure shredding operations generate revenue from the sale of shredded paper to recyclers. As a result,for recycling. Further, significant declines in the cost of paper may continue to negatively impact our revenues and results of operations, and increases in other commodity prices, including steel, may negatively impact our results of operations.
Failure to manage and adequately implement our new IT systems could negatively affect our business.
We may be subjectrely on IT infrastructure, including hardware, networks, software, people and processes, to claims thatprovide information to support assessments and conclusions about 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 thatoperating performance. We are the same or similar to those we use. Third parties have in the past,process of upgrading a number of our IT systems, including consolidating our existing billing systems, and we face risks relating to these transitions. For example, we may incur greater costs than we anticipate training our personnel on the new systems, we may experience service disruptions or errors in the future, bring claims,accurately capturing data or threaten to bring claims, against us that allege that their IP rights are being infringed or violated byretaining our use of IP. Litigation or threatened litigation could be costlyrecords, 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 requireddelayed in meeting our various reporting obligations. There can be no assurance that we will manage our IT systems and implement these new systems as planned or that we will do so without disruptions to 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 ofoperations, which could have an adverse effect on our business, lines, with our currentfinancial condition, results of operations and potential customers' internal storage and information management services capabilities and their cloud-based alternatives.

Part I
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, 2017,2020, our total long-term debt was approximately $7.1 billion.$8.7 billion, stockholders equity was approximately $1.1 billion and we had cash and cash equivalents (including restricted cash) of approximately $205.1 million. Our substantial indebtedness could have important consequences to our current and potential investors. These risks include:
inability to satisfy our obligations with respect to our various debt instruments;
inability to make borrowings to fund future working capital, capital expenditures and strategic opportunities, including acquisitions, further organic development of our Global Data Center Business and expansions into adjacent businesses, and other general corporate requirements, including possible required repurchases, redemptions or prepayments of our various indebtedness;
limits on our distributions to stockholders; in this regard if these limits prevented us from satisfying our REIT distribution requirements, we could fail to remain qualified for taxation as a REIT or, if these limits do not jeopardize our qualification for taxation as a REIT but do nevertheless prevent us from distributing 100% of our REIT taxable income, we will be subject to federal corporate income tax, and potentially a nondeductible excise tax, on the retained amounts;
limits on future borrowings under our existing or future credit arrangements, which could affect our ability to pay our indebtedness or to fund our other liquidity needs;
inability to generate sufficient funds to cover required interest payments;
restrictions on our ability to refinance our indebtedness on commercially reasonable terms;
limits on our flexibility in planning for, or reacting to, changes in our business and the information management services industry; and
inability to adjust to adverse economic conditions.conditions that could place us at a disadvantage to our competitors with less debt and who, therefore, may be able to take advantage of opportunities that our indebtedness prevents us from pursuing.
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, weWe are subject to increased risks associated with debt financing, including an increasedthe risk that our cash flow could be insufficient to meet required payments on our debt. In particular, if as a result of the COVID-19 pandemic our revenues, cash flows and/or Adjusted EBITDA continue to decline or we incur additional indebtedness, we may be unable to make required payments on our debt or to satisfy the financial and other covenants contained in our Credit Agreement (as defined in Note 6 to Notes to Consolidated Financial Statements included in this Annual Report) and our indentures. In addition, the expected elimination of the London Interbank Offered Rate (“LIBOR”) may adversely affect interest expense related to borrowings under certain of our credit arrangements and interest rate swaps, and could disrupt financial markets generally, which could potentially negatively impact our financial condition.
Despite our current indebtedness levels, we may still be able to incur substantially more debt. The terms of our indentures generally do not cap the maximum amount of additional funds that may be borrowed under our Credit Agreement and possible future credit arrangements.
Restrictive debt covenants may limit our ability to pursue our growth strategy.
Our indenturesCredit Agreement and our Credit Agreementindentures contain covenants restricting or limiting our ability to, among other things:
incur additional indebtedness;
pay dividends or make other restricted payments;
make asset dispositions;
create or permit liens; and
sell, transfer or exchange assets;
guarantee certain indebtedness;
make acquisitions and other investments.investments; and
enter into partnerships and joint ventures.
These restrictions and our long-term commitment to reduce our leverage ratio may adversely affect our ability to pursue our acquisition and other growth strategies.

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“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“change of control"control” under our indentures.

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.


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.RISKS RELATED TO OUR TAXATION AS 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.


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,year. We believe that our organization and method of operation comply with the rules and regulations promulgated under the Internal Revenue Code of 1986, as amended (the “Code”), such that we will continue to qualify for taxation as a REIT. However, we can provide no assurance that we will remain qualified for taxation as a REIT. If we fail to remain qualified for taxation as a REIT, we will be 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.provisions of the Code.
If, in any taxable year, we fail to remain qualified for taxation as a REIT and are not entitled to relief under the Code:
we will not be allowed a deduction for distributions to stockholders in computing our taxable income;
we will be subject to federal and state income tax on our taxable income at regular corporate income tax rates; and
we would not be eligible to elect REIT status again until the fifth taxable year that begins after the first year for which we failed to qualify for taxation as a REIT.
Any such corporate tax liability could be substantial and would reduce the amount of cash available for other purposes.
If we fail to remain qualified for taxation as a REIT, we may need to borrow additional funds or liquidate some investments to pay any additional tax liability. Accordingly, funds available for investment and distributions to stockholders could be reduced.

As a REIT, failure to make required distributions would subject us to federal corporate income tax.
We expect to continue paying regular quarterly distributions; however, the amount, timing and form of our regular quarterly distributions will be determined, and will be subject to adjustment, by our board of directors. To remain qualified for taxation as a REIT, we are generally required to distribute at least 90% of our REIT taxable income (determined without regard to the dividends paid deduction and excluding net capital gain) each year, or in limited circumstances, the following year, to our stockholders. Generally, we expect to distribute all or substantially all of our REIT taxable income. If our cash available for distribution falls short of our estimates, we may be unable to maintain distributions that approximate our REIT taxable income and may fail to remain qualified for taxation as a REIT. In addition, our cash flows from operations may be insufficient to fund required distributions as a result of differences in timing between the actual receipt of income and the payment of expenses and the recognition of income and expenses for federal income tax purposes, or the effect of nondeductible expenditures, 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.expenditures.
To the extent that we satisfy the 90% distribution requirement but distribute less than 100% of our REIT taxable income, we will be subject to federal corporate income tax on our undistributed taxable income. In addition, we will be subject to a 4% nondeductible excise tax on our undistributed taxable income if the actual amount that we distribute to our stockholders for a calendar year is less than the minimum amount specified under the Code.

Part I
We may be required to borrow funds, sell assets or raise equity to satisfy our REIT distribution requirements, to comply with asset ownership tests or to fund capital expenditures, future growth and expansion initiatives.
In order to meet thesatisfy our REIT distribution requirements and maintain our qualification and taxation as a REIT, or to fund capital expenditures, future growth and expansion initiatives, we may need to borrow funds, sell assets or raise equity, even if our financial condition or the then-prevailing market conditions are not favorable for these borrowings, sales or offerings. 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 and our commitment to investors on dividend growth may increase theresult in increasing our financing we needneeds 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,ratings, which could negatively impact our ability to access credit markets. Further, certain of our current debt instruments limit the amount of indebtedness we and our subsidiaries may incur. Additional financing, therefore, may be unavailable, more expensive or restricted by the terms of our outstanding indebtedness. For a discussion of risks related to our substantial level of indebtedness, see "Risks Relating“Risks Related to Our Indebtedness."
WhetherComplying with REIT requirements may limit our flexibility, cause us to forgo otherwise attractive opportunities that 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 necessarywould otherwise pursue to execute our long-termgrowth 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"),TRSs, and to that extent limit our opportunities and our flexibility to change our business strategy. This may restrict our ability to enter into joint ventures or acquire minority interests of companies. Furthermore, acquisition opportunities in domestic and international markets may be adversely affected if we need or require the target company to comply with some REIT requirements prior to closing.

We conduct a significant portion of our business activities, including our information management services businesses and several of our international operations, through domestic and foreign TRSs. Under the Code, no more than 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 abilityIf we fail to fully deductcomply with specified asset ownership tests applicable to REITs as measured at the end of any calendar quarter, we generally must correct such failure within 30 days after the end of the applicable calendar quarter or qualify for statutory relief provisions to avoid losing our interest expense may be limited, orqualification for taxation as a REIT. As a result, we may be required to adjust the tax depreciationliquidate assets or to forgo our pursuit of otherwise attractive investments. These actions may reduce our real property in orderincome and amounts available for distribution 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.stockholders.
As a REIT, we are limited in our ability to fund distribution payments using cash generated through our TRSs.
Our ability to receive distributions from our TRSs is limited by the rules with which we must comply to maintain our qualification for taxation as a REIT. In particular, at least 75% of our gross income for each taxable year as a REIT must be derived from real estate, which principallygenerally 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, andwhich 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 TRSsoperations are conducted overseas, and a material change in foreign currency rates could also affect the value of our foreign holdings in our TRSs, negatively impactimpacting our ability to remain qualified for taxation as a REIT.
The Tax Reform Legislation has imposed limitations on the ability
IRON MOUNTAIN 2020 FORM 10-K17


Part I
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,including taxes on any undistributed income, and state, local or foreign income, franchise, property and transfer taxes. In addition, we could in certain circumstances be required to pay an excise or penalty tax, which could be significant in amount, in order to utilize one or more relief provisions under the Code to maintain our qualification for taxation as a REIT.
Our information management services businesses and severalA portion of our international operations arebusiness is conducted through wholly ownedwholly-owned TRSs because thesecertain of our business activities could generate nonqualifying REIT income as currently structured and operated. The income of our domestic TRSs will continue to be subject to federal and state corporate income taxes. In addition, weour international assets and our subsidiariesoperations will continue to be subject to taxation in the foreign income taxes in jurisdictions in which we have business operations or a taxable presence, regardless of whetherwhere those assets are held or those operations are conducted through subsidiaries disregarded for federal income tax purposes or TRSs.conducted. 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 gainsgain 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"(“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, any depreciation recapture income that we expect to recognize as a resultbecause of certain accounting method changes that we have mademake in connection with our acquisition activities 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-Unitednon- United States operations, as well as income from qualifying counteracting hedges, do not constitute "gross income"“gross income” for purposes of the REIT gross income tests. To the extent that we enter into other types of hedging transactions, the income from those transactions is likely to be treated as nonqualifying income for purposes of the REIT gross income tests. As a result of these rules, we may need to limit our use of advantageous hedging techniques or implement those hedges through our TRSs. This could increase the cost of our hedging activities because our TRSs would be subject to tax on income or gains resulting from hedges entered into by them and may expose us to greater risks associated with changes in interest rates or exchange rates than we would otherwise want to bear. In addition, hedging losses in any of our TRSs generally will not provide any tax benefit, except for being carried forward for possible use against future income or gain in the TRSs.

Distributions payable by REITs generally do not qualify for preferential tax rates.
Dividends payable by United States corporations to noncorporate stockholders, such as individuals, trusts and estates, are generally eligible for reduced United States federal income tax rates applicable to “qualified dividends.” Distributions paid by REITs generally are not treated as “qualified dividends” under the Code, and the reduced rates applicable to such dividends do not generally apply. However, for tax years beginning 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.year. In addition, rents from "affiliated tenants"“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"“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, or local laws impacting our REIT structure for our international operations may be amended. Federal, state and statelocal tax laws are constantly under review by persons involved in the legislative process, the IRS, the United States Department of the Treasury (the "Treasury"(“Treasury”) and state and local taxing authorities. Changes to the tax laws, regulations and administrative interpretations or local laws governing our international operations, which may have retroactive application, could adversely affect us. In addition, some of these changes could have a more significant impact on us as compared to other REITs due to the nature of our business and our substantial use of TRSs, particularly non-United States TRSs.

The Tax Reform Legislation has made substantial changes toTRSs or how we have structured our operations outside 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 orderUnited States to comply with our REIT structure.We cannot predict with certainty whether, when, in what forms, or with what effective dates, 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 Treasurytax laws, regulations, in orderadministrative interpretations or local laws applicable to assess their effect.  Thereus may be changed or if such laws would impact our ability to qualify for taxation as a substantial delay before such regulationsREIT or the costs for doing so.

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.

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.


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:
 Year Ended December 31,
 2015 2016 2017
Nonqualified ordinary dividends49.3% 45.5% 82.1%
Qualified ordinary dividends39.1% 21.0% 17.9%
Return of capital11.6% 33.5% %
 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 inSee Note 78 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 Legislationadditional information 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.

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.stock.
Unregistered Sales of Equity Securities and Use of ProceedsUNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS
We did not sell any unregistered equity securities during the three months ended December 31, 2017,2020, nor did we repurchase any shares of our common stock during the three months ended December 31, 2017.2020.

OVERVIEW
COVID-19
In March 2020, the World Health Organization declared COVID-19 a pandemic. This resulted in U.S. federal, state and local and foreign governments and private entities mandating various restrictions, including travel restrictions, restrictions on public gatherings and stay-at-home orders and advisories. In response, we temporarily closed certain of our offices and facilities across the world and implemented certain travel restrictions for our employees. The preventative and protective actions that governments have ordered, or we or our customers have implemented, have resulted in a period of reduced service operations and business disruption for us, our customers and other third parties with which we do business. While we have broad geographic and customer diversification with operations in 56 countries and no single customer accounting for more than 1% of our revenue during the year ended December 31, 2020, COVID-19 is a global pandemic impacting numerous industries and geographies. While we do not currently believe that the implications of the COVID-19 pandemic have had a material adverse impact on our ability to collect our accounts receivable, global economic conditions related to the COVID-19 pandemic may have a material adverse effect on our customers, which could impact our future ability to collect our accounts receivable. We continue to monitor the credit worthiness of our customers and customer payment trends, as well as the related impact on our liquidity.
We have taken certain actions during the year ended December 31, 2020 to manage our costs and capital expenditures, including, but not limited to: (i) the termination of nearly all of our temporary and contract workers; (ii) reductions in our full-time and part-time work forces; (iii) temporary furloughs, reduced hours or other temporary reduction measures; (iv) the deferral of certain previously planned non-essential capital investments; and (v) the implementation of a temporary freeze on future acquisitions. We can provide no assurance that the cost savings measures we have taken, or may take in future periods, will be sufficient to offset any future service level declines, and we continue to evaluate the need for these cost saving measures and additional cost saving measures as additional information regarding the COVID-19 pandemic and the related economic downturn becomes known. We have incurred certain costs due to the COVID-19 pandemic which are direct, incremental and not expected to recur once the pandemic ends, which include the purchase of personal protective equipment for our employees and incremental cleaning costs of our facilities, among other direct costs. We have excluded these costs in calculating our various non-GAAP measures as described below.

In October 2019, we announced Project Summit, our global program designed to better position us for future growth and achievement of our strategic objectives. We expanded Project Summit during the first quarter of 2020 to include additional opportunities to streamline our business and operations, as well as accelerated the timing of certain opportunities previously identified. Such opportunities include leveraging new technology solutions to enable us to modernize our service delivery model and more efficiently utilize our fleet, labor and real estate. As a result of the program, we expect to reduce the number of positions at vice president and above by approximately 45%. The total program is expected to reduce our total managerial and administrative workforce by approximately 700 positions by the end of 2021. We have also reduced our services and operations workforce. As of December 31, 2020, we have completed approximately 70% of our planned workforce reductions.

26IRON MOUNTAIN 2020 FORM 10-K

The activities associated with Project Summit began in the fourth quarter of 2019 and are expected to be substantially complete by the end of 2021. We expect the total program benefits associated with Project Summit to be fully realized exiting 2021. Including the expanded scope of Project Summit, we expect that Project Summit will improve annual Adjusted EBITDA (as defined below) by approximately $375.0 million exiting 2021. We will continue to evaluate our overall operating model, as well as various opportunities and initiatives, including those associated with real estate consolidation, system implementation and process changes, which could result in the identification and implementation of additional actions associated with Project Summit and incremental costs and benefits.

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

We have also incurred approximately $10.1 million in capital expenditures related to Project Summit from the inception of Project Summit through December 31, 2020.
DIVESTMENTS
In March 2019, we contributed our customer contracts and certain intellectual property and other assets used by us to operate our consumer storage business in the United States and Canada (the “IM Consumer Storage Assets”) and approximately $20.0 million in cash (gross of certain transaction expenses) (the “Cash Contribution”) to the MakeSpace JV (the “Consumer Storage Transaction”), we completed the Recall Transaction. Atestablished by us and MakeSpace. Upon the closing of the RecallConsumer Storage Transaction on March 19, 2019, the MakeSpace JV owned (i) the IM Consumer Storage Assets, (ii) the Cash Contribution and (iii) the customer contracts, intellectual property and certain other assets used by MakeSpace to operate its consumer storage business in the United States. As part of the Consumer Storage Transaction, we paidreceived an initial equity interest of approximately $331.834% in the MakeSpace JV (the “MakeSpace Investment”). In the second quarter of 2020, we committed to participate in a round of equity funding for the MakeSpace JV whereby we agreed to contribute $36.0 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$45.0 million being raised in a total purchase price to Recall shareholders of approximately $2,166.9 million. The results of operations of Recall have been includedinstallments beginning 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 ended2020 through October 2021. At December 31, 2015 and 2016, respectively.2020, we owned approximately 39% of the outstanding equity in the MakeSpace JV.
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 definedAs described 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.


Divestitures

a. Divestments Associated with the Recall Transaction
As disclosed in Note 64 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 Divestmentdivestment of the IM Consumer Storage Assets in the Consumer Storage Transaction does not meet the criteria to be reported as discontinued operations in our consolidated financial statements, as our decisionstatements. In connection with the Consumer Storage Transaction and the MakeSpace Investment, we also entered into a storage and service agreement with the MakeSpace JV to divest these businesses does not represent a strategic shift that will have a major effect on our operationsprovide certain storage and financial results. Accordingly,related services to the revenuesMakeSpace JV (the “MakeSpace Agreement”). Revenues and expenses associated with these businessesthe MakeSpace Agreement are presented as a component of income (loss) from continuing operations in our Consolidated Statements of Operations forGlobal RIM Business segment. During the years ended December 31, 2015, 20162020 and 2017,2019, we recognized revenue of approximately $33.6 million and $22.5 million, 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.

CHANGES IMPACTING COMPARABILITY WITH PRIOR YEAR
During the thirdfourth quarter of 2015,2020, we made changes to the definitions of the following non-GAAP measures: Adjusted EBITDA, Adjusted EPS, FFO (Nareit) and FFO (Normalized) (each as defined below). These changes were implemented a plan that callsto align our definitions more closely with our peers. These changes impacted the results reported for certain organizational realignmentsthese non-GAAP measures for fiscal years 2019 and 2018. However, these changes did not materially impact the discussion to reduce our overhead costs, particularlywhat was included in previous filings. All prior periods have been recast to conform to these changes. See “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” 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 millionAnnual Report on Form 10-K for the yearsyear ended December 31, 2015, 2016 and 2017, respectively, primarily related2019 for a comparison of 2019 to employee severance and associated benefits.2018.

Through December 31, 2017,COVID-19 pandemic, we have recorded cumulative chargesexperienced relatively steady volume in our Global RIM Business segment, with organic storage rental revenue growth driven primarily by revenue management. We expect organic storage rental revenue growth to benefit from revenue management and volume to be relatively stable in the near term. We expect our Consolidated Statementstotal organic storage rental revenue growth rate for 2021 to be approximately 2% to 4%.
Our organic service revenue during 2020 was significantly impacted by the COVID-19 pandemic, with declines primarily due to decreases in our service activity, particularly in regions where governments have imposed restrictions on our customers’ non-essential business operations. The severity of Operations associated withfuture service level declines is uncertain and is dependent, in part, on the Transformation Initiativeduration and severity of $16.7 million.

Generalthe COVID-19 pandemic, the resulting governmental and business actions and the duration and strength of any ensuing economic recovery that may follow, particularly within the markets in which we operate and among our customers.
Our revenues consist of storage rental revenues as well as service revenues and are reflected net of sales and value addedvalue-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, the most significant of which include: (1) the handling of records, including the addition of new records, temporary removal of records from storage, refiling of removed records, customer termination and the destruction of records; (2)permanent withdrawal fees, project revenues, and courier operations, consisting primarily of the pickup and delivery of records upon customer request; (3)(2) destruction services, consisting primarily of secure shredding of sensitive documents and the relatedsubsequent sale of recycledshredded paper for recycling, the price of which can fluctuate from period to period; (4) other services,and (3) digital solutions, 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).services. 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 labor, including wages and benefits for field personnel, facility occupancy costs (including rent and utilities), transportation expenses (including vehicle leases and fuel), other product cost of sales and other equipment costs and supplies. Of these, wages and benefitslabor 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 costCost of sales components(excluding depreciation and selling, generalamortization) 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.

The expansion of our international businesses has impacted the major cost of sales components and selling, general and administrative expenses.
Our international operations are more labor intensive relative to revenue than our operations in North America and, therefore, labor costs are a higher percentage of international operational revenue.
The overhead structure of our expanding international operations has generally not achieved the same level of overhead leverage as our North American operations, which may result in an increase in selling, general and administrative expenses as a percentage of consolidated revenue as our international operations become a larger percentage of our consolidated results.
Our depreciation and amortization charges result primarily from the capital-intensive nature of our business. The principal components of depreciation relaterelated to storage systems, which include racking structures, buildings, building and leasehold improvements and computer systems hardware and software. Amortization relates primarily to customer relationship intangible assets, contract fulfillment costs and data center lease-based intangible assets. Both depreciation and amortization are impacted by the timing of acquisitions.

Our consolidated revenues and expenses are subject to the net effect of foreign currency translation related to our entitiesoperations 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 20152019 results at the 20162020 average exchange rates and the 20162018 results at the 20172019 average exchange rates. Constant currency growth rates are a non-GAAP measure.

During the fourth quarter of 2020, we changed our definition of Adjusted EBITDA is definedto (a) exclude stock-based compensation expense and (b) include our share of Adjusted EBITDA from our unconsolidated joint ventures. We now define Adjusted EBITDA as income (loss) from continuing operations before interest expense, net, provision (benefit) for income taxes, depreciation and amortization (inclusive of our share of Adjusted EBITDA from our unconsolidated joint ventures), and also excludesexcluding certain items that we do not believe are notto be 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 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 also does not include depreciation and amortization expenses, in order to eliminate the impact of capital investments, which we evaluate by comparing capital expenditures to incremental revenue generated and as a percentage of total revenues. Adjusted EBITDA and Adjusted EBITDA Margin should be considered in addition to, but not as a substitute for, other measures of financial performance reported in accordance with accounting principles generally accepted in the United States of America ("GAAP"(“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).

Funds from operations (“FFO”("FFO") is defined by the National Association of Real Estate Investment Trusts ("Nareit"(“Nareit”) and us as net income (loss) excluding depreciation on real estate assets, and gaingains on sale of real estate, net of tax, (“and amortization of data center leased-based intangibles. Consistent with Nareit's definition of FFO, during the fourth quarter of 2020, we began adjusting for our share of reconciling items from our unconsolidated joint ventures from FFO ("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. income (loss).
Although Nareit has published a definition of FFO, modifications towe modify FFO (Nareit) are, as is common among REITs as companies seekseeking to provide financial measures that most meaningfully reflect their particular business.business ("FFO (Normalized)"). During the fourth quarter of 2020, we changed our definition of FFO (Normalized) to exclude stock-based compensation expense and adjust for our share of FFO (Normalized) reconciling items from our unconsolidated joint ventures.

Critical Accounting PoliciesCRITICAL ACCOUNTING ESTIMATES
Our discussion and analysis of our financial condition and results of operations are based upon our Consolidated Financial Statements, which have been prepared in accordance with GAAP. The preparation of these financial statements requires us to make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities at the date of the financial statements and for the period then ended. On an ongoing basis, we evaluate the estimates used. We base our estimates on historical experience, actuarial estimates, current conditions and various other assumptions that we believe to be reasonable under the circumstances. These estimates form the basis for making judgments about the carrying values of assets and liabilities and are not readily apparent from other sources. Actual results may differ from these estimates. The following should be read in conjunction with Note 2 to Notes to Consolidated Financial Statements included in this Annual Report, which provides a summary of our significant accounting policies. Our critical accounting policiesestimates include the following, which are listed in no particular order:
IRON MOUNTAIN 2020 FORM 10-K33

REVENUE RECOGNITION
Revenue Recognitionis recognized when or as control of promised goods or services is transferred to the customer, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services. See Note 2.r. to Notes to Consolidated Financial Statements included in this Annual Report for additional details on our revenue recognition policies. Revenue for all our lines of business, with the exception of storage revenues in our Global Data Center Business (which is subject to leasing guidance), is recognized under Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”), the application of which requires that we make estimates and judgements that may affect the amount and timing of revenue we recognize.
We recognize revenue whenhave determined that the following criteria are met: persuasive evidencemajority of an arrangement exists, services have been rendered,our contracts contain series performance obligations which qualify to be recognized under a practical expedient available in ASU 2014-09 known as the sales price is fixed or determinable“right to invoice.” This determination allows variable consideration in such contracts to be allocated to and collectability of the resulting receivable is reasonably assured. Storage rental and service revenues are recognized in the monthperiod to which the respective storage rental or serviceconsideration relates, which 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 overtypically the period in which it is billed, rather than requiring estimation of variable consideration at the applicable storage rental or serviceinception of the contract.
From time to time, we make payments to entities that are also customers under a revenue contract. These payments are comprised of Customer Inducements (as defined in Note 2.l. to Notes to Consolidated Financial Statements included in this Annual Report). Consideration payable to a customer is provided or performed. Revenues fromreviewed as part of the sales of products, which are included as a component of service revenues, are recognized when products are shipped and title has passedtransaction price. If the payment to the customer.

Contract Fulfillment Costs are amortized over a three year term, which we have historically not been significant.determined is consistent with the transfer of the underlying performance obligations to which the assets relate. Different determinations on term length would result in differences in the amount and timing of amortization expense recognized.
Accounting for AcquisitionsACCOUNTING FOR ACQUISITIONS
Part of our growth strategy has included the acquisition by us of numerousbeen to acquire businesses. The purchase price of each acquisition has been determined after due diligence of the target business, market research, strategic planning and the forecasting of expected future results and synergies. Estimated future results and expected synergies are subject to revisions as we integrate each acquisition and attempt to leverage resources.
During the third quarter of 2017, we adopted Accounting Standards Update No. 2017-01, Business Combinations (Topic 805): Clarifying the Definitionfor acquisitions 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 data center lease-based intangible assets), property, plant and equipment (primarily building, building improvements, leasehold improvements, data center infrastructure and racking structures), operating leases, contingencies and income taxes (primarily deferred income taxes). 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 63 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'smanagement’s judgment and often involves the use of assumptions with respect to future cash inflows and outflows, discount rates and market data, among other items. As it relates to our data center acquisitions, the fair values of the net assets acquired requires management’s judgment and often involves the use of assumptions with respect to (i) certain economic costs (as described more fully in Note 2.l. to Notes to Consolidated Financial Statements included in this Annual Report) avoided by acquiring a data center operation with active tenants that would have otherwise been incurred if the data center operation was purchased vacant, (ii) market rental rates and (iii) expectations of lease renewals and extensions. Due to the inherent uncertainty of future events, actual values of net assets acquired could be different from our estimated fair values and could have a material impact on our financial statements.

Of the net assets acquired in our acquisitions, the fair value of owned buildings, including building improvements, customer relationship and data center lease-based intangible assets, racking structures and operating leases are generally the most common and most significant. For significant acquisitions or acquisitions involving new markets or new products, we generally use third parties to assist us in estimating the fair value of owned buildings, including building improvements, customer relationship and lease-based intangible assets and market rental rates for acquired operating leases. For acquisitions that are not significant or do not involve new markets or new products, we generally use third parties to assist us in estimating the fair value of acquired owned buildings, including building improvements, and market rental rates for acquired operating leases. When not using third party appraisals of the fair value of acquired net assets, the fair value of acquired customer relationship and leased-based intangible assets, above and acquiredbelow market in-place operating leases, and racking structures is determined internally. The fair value of acquired racking structures is determined internally by taking current estimated replacement cost at the date of acquisition for the quantity of racking structures acquired, discounted to take into account the quality (e.g. age, material and type) of the racking structures. We use discounted cash flow models to determine the fair value of customer relationship 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 We determine the fair value of customer relationship intangibletangible data center assets acquired inusing an estimated replacement cost at the Bonded Transaction (onedate of our more significant acquisitions in fiscal year 2017), a hypothetical increaseacquisition, then discounting for age, economic and functional obsolescence.

Our estimates of fair value are based upon assumptions believed to be reasonable at that time but which are inherently uncertain and unpredictable. Assumptions may be incomplete or inaccurate, and unanticipated events and circumstances may occur, which may affect the accuracy of such assumptions. Total property, plant and equipment and intangible assets acquired in our 2020 acquisitions were approximately $52.0 million and $79.1 million, respectively.
Impairment of Tangible and Intangible AssetsIMPAIRMENT OF TANGIBLE AND INTANGIBLE ASSETS 
Assets subject to depreciation or amortization:ASSETS SUBJECT TO DEPRECIATION OR AMORTIZATION 
We review long-lived assets and all finite-lived intangible assets for impairment whenever events or changes in circumstances indicate the carrying amount of such assets may not be recoverable. Examples of events or circumstances that may be indicative of impairment include, but are not limited to:
A significant decrease in the market price of an asset;
A significant change in the extent or manner in which a long-lived asset is being used or in its physical condition;
A significant adverse change in legal factors or in the business climate that could affect the value of the asset;
An accumulation of costs significantly greater than the amount originally expected for the acquisition or construction of an asset;
A current-period operating or cash flow loss combined with a history of operating or cash flow losses or a projection or forecast that demonstrates continuing losses associated with the use of a long-lived asset; and
A current expectation that, more likely than not, an asset will be sold or otherwise disposed of significantly before the end of its previously estimated useful life.
If events indicate the carrying value of such assets may not be recoverable, recoverability of these assets is determined by comparing the sum of the forecasted undiscounted net cash flows of the operation to which the assets relate to their carrying amount. The operations are generally distinguished by the business segment and geographic region in which they operate. If it is determined that we are unable to recover the carrying amount of the assets, the long-lived assets are written down, on a pro rata basis, to fair value. Fair value is determined based on discounted cash flows or appraised values, depending upon the nature of the assets.

GOODWILL AND OTHER INDEFINITE-LIVED INTANGIBLE ASSETS NOT SUBJECT TO AMORTIZATION
Goodwill and other indefinite-lived intangible assets not subject to amortization:Goodwill and intangible assets with indefinite lives are not amortized but are reviewed annually for impairment, or more frequently if impairment indicators arise. Other than goodwill, we currently have no intangible assets that have indefinite lives and which are not amortized. See Note 2.k. to Notes to Consolidated Financial Statements included in this Annual Report for additional details on our goodwill and other indefinite-lived intangible assets policies.
We have selected October 1 as our annual goodwill impairment review date. We have performed our annual goodwill impairment review as of October 1, 20152020, 2019 and 2016, concluding2018. We concluded that no goodwill was impaired as of such dates. We performed our annual goodwill impairment review as of October 1, 20172020, 2019 and as2018, goodwill was not impaired.
During the first quarter of 2020, we concluded that we had a resulttriggering event related to our Fine Arts reporting unit, requiring us to perform an interim goodwill impairment test. The primary factor contributing to our conclusion was the expected impact of the COVID-19 pandemic to this particular business and its customers and revenue sources, which caused us to believe it was more likely than not that review,the carrying value of our Fine Arts reporting unit exceeded its fair value. Therefore, we determinedperformed an interim goodwill impairment test for our Fine Arts reporting unit utilizing a discounted cash flow model, with updated assumptions on future revenues, operating expenditures and capital expenditures. We concluded that the fair value of the Consumer Storageour Fine Arts 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$23.0 million impairment charge on the goodwill associated with this reporting unit during the fourthfirst quarter of 2017, which represents a write-off of all goodwill associated2020. Factors that may impact these assumptions include, but are not limited to: (i) our ability to maintain, or grow, storage rental and service revenues in line with this reporting unit. We concluded that goodwill associatedcurrent expectations and (ii) our ability to manage our fixed and variable costs in line with the remainder of our reporting units was not impaired as of October 1, 2017. potential future revenue declines.

Our Fine Arts business operatesGlobal Data Center Business footprint spans nine markets in a growing,the United States: Denver, Colorado; Kansas City, Missouri; Boston, Massachusetts; Boyers, Pennsylvania; Manassas, Virginia; Edison, New Jersey; Columbus, Ohio; and Phoenix and Scottsdale, Arizona and four international markets: Amsterdam, London, Singapore and, through an unconsolidated joint venture, Frankfurt. We provide mission-critical data centers that are designed and operated to protect and ensure the continued operation of IT infrastructure for our customers. Data centers are highly specialized and secure assets that serve as centralized repositories of server, storage and network equipment. They are capital intensive and designed to provide the space, power, cooling and network connectivity necessary to efficiently operate mission-critical IT equipment. The demand for data center infrastructure is being driven by many factors, but fragmented, industry markedmost importantly by increasing international interestsignificant growth in data as well as an increased demand for outsourcing. In order to attract and changesretain customers, as well as sustain growth in purchasing habits by collectorsour existing and museums. We believenew markets, we must have the increase in contemporary art as a focus for collectors will result in increasing storage needs, whilecapability to tailor our facilities and invest capital to meet 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 growthcustomers’ needs. Our estimate 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 reflects the expected growth in each of our data center markets along with the Fine Arts reporting unit reflect this growth potential and thecorresponding capital needsinvestments required to respond to the expansion opportunities.meet demand. The Fine Arts reporting unitbusiness is primarily composedcomprised of a business we acquiredacquisitions completed in the fourth quarter of 2015;2018 and late 2017; therefore, we would expect that 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 towill 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 legalregulatory 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 ApproachDiscounted Cash Flow Model and Market Approach for each of the reporting units, or future adverse market conditions not currently known, could lead to a fair value that is less than the carrying value in any one of our reporting units.

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 arehave generally been determined using a combined approach based on the present value of future cash flows (the "Income Approach")Discounted Cash Flow Model and market multiples (the "Market Multiple Approach").Market Approach. The Income ApproachDiscounted Cash Flow Model incorporates manysignificant assumptions including future revenue growth rates, and operating margins, discount rate factors, expectedrates and capital expenditures and income tax cash flows.expenditures. The Market Approach requires us to make assumptions related to Adjusted EBITDA multiples. Changes in economic and operating conditions impacting these assumptions or changes in multiples could result in goodwill impairments in future periods. In conjunction with our annual goodwill impairment reviews, we reconcile the sum of the valuations of all of our reporting units to our market capitalization as of such dates.

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) 2020.

We noted that, based on the estimated fair value of these reporting units determined as of October 1, 2020:
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, 2020 by a range of approximately 9.7% to 10.6% but would not, however, have resulted in the carrying value of any of these reporting units with goodwill exceeding their estimated fair value;
a hypothetical increase of 100 basis points in the discount rate, with all other assumptions unchanged, would have decreased the estimated fair value of these reporting units as of October 1, 2020 by a range of approximately 4.6% to 10.7% but would not, however, have resulted in the carrying value of any of these reporting units with goodwill exceeding their estimated fair value.
Global Data Center
We noted that, as of October 1, 2020, the estimated fair value of the reporting unit:
exceeds its carrying value by less than 20%.
Accordingly, any significant negative change in either the expected annual future cash flows of the reporting unit or the discount rate may result in the carrying value of the reporting unit exceeding its estimated fair value.
At December 31, 2020, no factors were identified that would alter the conclusions of our October 1, 2020 goodwill impairment analysis. In making this assessment, we considered a number of factors including operating results, business plans, anticipated future cash flows, oftransactions and marketplace data. There are inherent uncertainties related to 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 resultedfactors and our judgment 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 respectapplying them to the Fine Arts, Latin America and Australia and New Zealand reporting units, we noted that, asanalysis of October 1, 2017, the estimated fair value of these reporting units exceeds their carrying value by less than 20%.

Income TaxesINCOME TAXES
As a REIT, we are generally permitted to deduct from our federal taxable income the dividends we pay to our stockholders. The income represented by such dividends is not subject to federal taxation at the entity level but is taxed, if at all, at the stockholder level. The income of our domestic TRSs, which hold our domestic operations that may not be REIT-compliant as currently operated and structured, is subject, as applicable, to federal and state corporate income tax. In addition, we and our subsidiaries continue to be subject to foreign income taxes in other jurisdictions in which we have business operations or a taxable presence, regardless of whether assets are held or operations are conducted through subsidiaries disregarded for federal income tax purposes or TRSs. We will also be subject to a separate corporate income tax on any gains recognized on the sale or disposition of any asset previously owned by a C corporation during a five-year period followingafter the date on which that asset waswe first owned bythe asset as a REIT asset that are attributable to "built-in" gains"built-in gains" with respect to that asset on that date (e.g. with respectdate. We will also be subject to the REIT conversion, the assets that we owned on January 1, 2014). Thisa 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.our acquisition activities. If we fail to remain qualified for taxation as a REIT, we will be subject to federal income tax at regular corporate income tax rates. Even if we remain qualified for taxation as a REIT, we may be subject to some federal, state, local and foreign taxes on our income and property in addition to taxes owed with respect to our TRS operations. In particular, while state income tax regimes often parallel the federal income tax regime for REITs, many states do not completely follow federal rules and some do not follow them at all.

See Note 9 to Notes to Consolidated Financial Statements included in this Annual Report for additional details on our tax policies.
Accounting for income taxes requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the tax and financial reporting bases of assets and liabilities and for loss and credit carryforwards. We measure deferred tax assets and liabilities using enacted tax rates expected to be applied to taxable income in the years in which those temporary differences and carryforwards are expected to be recovered or settled. The effect on deferred tax assets and liabilities as a result of a change in tax rates is recognized in income in the period that the change is enacted. Valuation allowances are provided when recovery of deferred tax assets does not meet the more likely than not standard as defined in GAAP. Valuation allowances would be reversed as a reduction to the provision for income taxes if related deferred tax assets are deemed realizable based on changes in facts and circumstances relevant to the recoverability of the asset.

We
IRON MOUNTAIN 2020 FORM 10-K37

At December 31, 2020, 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 haveand state net operating loss carryforwards which expire from 2018 through 2036, of which we are expecting an insignificant state tax benefit is expected to be realized. We have assets for foreign net operating losses of $103.6$92.1 million, with various expiration dates (and in some cases no expiration date), subject to a valuation allowance of approximately 59%43%. If actual results differ unfavorably from certain of our estimates used, we may not be able to realize all or part of our net deferred income tax assets and additional valuation allowances may be required. Although we believe our estimates are reasonable, no assurance can be given that our estimates reflected in the tax provisions and accruals will equal our actual results. These differences could have a material impact on our income tax provision and operating results in the period in which such determination is made.

The evaluation of an uncertain tax position is a two-step process. The first step is a recognition process whereby we determine whether it is more likely than not that a tax position will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. The second step is a measurement process whereby a tax position that meets the more likely than not recognition threshold is calculated to determine the amount of benefit to recognize in the financial statements. The tax position is measured as the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement.
We are subject to income taxes in the United States and numerous foreign jurisdictions. We are subject to examination by various tax authorities in jurisdictions in which we have business operations or a taxable presence. We regularly assess the likelihood of additional assessments by tax authorities and provide for these matters as appropriate. As of December 31, 20162020 and 2017,2019, we had approximately $59.5$26.0 million and $38.5$35.1 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 As of December 31, 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 inStates. With the amountexception 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,certain limited instances, we no longer provide incremental foreign withholding taxes on the retained book earnings of these unconverted foreign TRSs, which was approximately $230.0$262.4 million as of December 31, 2017.2020. 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 DecemberRESULTS OF OPERATIONS
COMPARISON OF 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 December2020 TO YEAR ENDED 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 December2019 AND COMPARISON OF YEAR ENDED 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 December2019 TO YEAR ENDED 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(IN THOUSANDS):
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.

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(1)See “Non-GAAP Measures—Adjusted EBITDA” in this Annual Report for additionalthe definitions of Adjusted EBITDA and Adjusted EBITDA Margin, reconciliation of Adjusted EBITDA to Income (Loss) from Continuing Operations and a discussion of why we believe these non-GAAP measures provide relevant and useful information regarding the uncertainty pertaining to income that we are required to recognize on accountour current and potential investors.

IRON MOUNTAIN 2020 FORM 10-K38

REVENUES
Consolidated revenues consist 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
InFor the year ended December 31, 2017,2020, the increasedecrease in reported consolidated storage revenue was driven by the favorable impact of acquisitions/divestitures, consolidated internal storage rentaldeclines in reported service revenue growth and favorable fluctuations in foreign currency exchange rates. The net impact of acquisitions/divestitures contributed 6.5% to thepartially offset by reported storage rental revenue growthgrowth. Foreign currency exchange rate fluctuations decreased our reported consolidated revenues by 1.0% in the year ended December 31, 2020 compared to the prior year period.
STORAGE RENTAL REVENUES AND SERVICE REVENUES
Primary factors influencing the change in reported storage rental revenue and reported service revenue for the year ended December 31, 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 rates2020 compared to the year ended December 31, 2015. The net impact of acquisitions/divestitures contributed 16.8% to2019 include 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.following:
Service Revenues
STORAGE RENTAL REVENUES
organic storage rental revenue growth driven by volume growth in faster growing markets and revenue management;
a 2.1% increase in global records management volume due to acquisitions (excluding acquisitions, global records management volume decreased 1.1%); and
a decrease of $29.1 million due to foreign currency exchange rate fluctuations.
SERVICE REVENUES
a decrease in service activity as a result of the COVID-19 pandemic, particularly in regions where governments have imposed restrictions on our customers' non-essential business operations;
organic service revenue declines reflecting lower service activity levels; and
a decrease of $15.7 million due to foreign currency exchange rate fluctuations.
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.Part II

Labor

Labor expenses decreased to 20.4%Primary factors influencing the change in reported consolidated Cost 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 expensessales 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, 20162020 compared to the year ended December 31, 2015, as decreases in labor expenses as 2019 include the following:
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 revenuecosts driven by cost containment actions taken in response to lower service activity levels due to the COVID-19 pandemic, partially offset by incremental labor costs associated with our North American Records and Information Management Business segment was primarily associated with wages and benefits growing at recent acquisitions;
a lower rate than revenue, partially attributable to synergies associated with our acquisition of Recall. The 52 basis point increasedecrease 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,transportation costs primarily driven by our acquisition of Recall.lower third party carrier cost and fuel cost reflecting cost containment actions taken in response to lower service activity levels;


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 pointsan increase in facilities expenses as a percentage of consolidated revenues was primarily driven by an increaseincreases in rent expense, in part due to recent acquisitions and the impact from our recent sale-leaseback activity (which we expect to continue in 2021 as we continue to look for future opportunities to monetize a resultsmall portion of the acquisition of Recall, as Recall'sour owned industrial real estate portfolio contains a more significant proportionassets as part 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.ongoing capital recycling program); and
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 $107.6of $23.5 million or 25.9%, on a constant dollar basis compareddue to the prior year period, primarily driven by our acquisitionforeign currency exchange rate fluctuations.

TransportationPart II
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.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES
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

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.

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 Statementsboth included in this Annual Report, for a description of our reportable operating segments.

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, 2016.2020 compared to the year ended December 31, 2019 include the following:
a decline in organic service revenue due to lower service activity levels in our Fine Arts business, primarily related to the COVID-19 pandemic; and

a decrease in Adjusted EBITDA reflecting the impact of lower service activity in our Fine Arts business, increased information technology expenses and higher bonus compensation accruals, partially offset by benefits from Project Summit.

a. Credit Agreement
On August 21, 2017, we entered into a newOur 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“Revolving Credit Facility"Facility”) and a term loan (the "Term Loan"“Term Loan A”). 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. Under the Credit Agreement, we have the option to request additional commitments of up to $1,260.0 million, in the form of term loans or through increased commitments under the Revolving Credit Facility, subject to the conditions specified in the Credit Agreement. The Credit Agreement is scheduled to mature on June 4, 2023, at which point all obligations become due. The original principal amount of the Term Loan A was $250.0 million and is to be paid in quarterly installments in an amount equal to $3.1 million per quarter, with the remaining balance due on August 21, 2022.June 4, 2023.
IMI and the Guarantors guarantee all obligations under the Credit Agreement. The interest rate on borrowings under the Credit Agreement varies depending on our choice of interest rate and currency options, plus an applicable margin, which varies based on our consolidated leverage ratio. Additionally, the Credit Agreement requires the payment of a commitment fee on the unused portion of the Revolving Credit Facility, which fee ranges from between 0.25% to 0.4% based on our consolidated leverage ratio and fees associated with outstanding letters of credit. As of December 31, 2017,2020, we had $466.6 million and $243.8 million ofno outstanding borrowings under the Revolving Credit Facility and $215.6 million aggregate outstanding principal amount under the Term Loan respectively.

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

Part II
On March 31, 2020, we amended the Accounts Receivable Securitization Program to (i) increase the maximum amount available from $275.0 million to $300.0 million and (ii) extend the maturity date from July 30, 2020 to July 30, 2021, at which point all obligations become due. The full amount outstanding under the Accounts Receivable Securitization Program is classified within the current portion of long-term debt in our Consolidated Balance Sheet as of December 31, 2020. As of December 31, 2020, the maximum availability allowed and amount outstanding under the Accounts Receivable Securitization Program was $274.1 million and $85.0 million, respectively. The interest rate in effect under the Revolving Credit FacilityAccounts Receivable Securitization Program was 3.5% and ranged from 3.4% to 5.5%1.1% as of December 31, 2017 and the interest2020. Commitment fees at a rate in effectof 40 basis points are charged on amounts made available but not borrowed under the Term Loan asAccounts Receivable Securitization Program.
LETTERS OF CREDIT
As of December 31, 2017 was 3.5%2020, we had outstanding letters of credit totaling $36.2 million, of which $3.2 million reduce our borrowing capacity under the Revolving Credit Facility (as described above). The letters of credit expire at various dates between January 2021 and January 2033.

DEBT COVENANTS
The Credit Agreement (as defined in Note 6 to Notes of Consolidated Financial Statements included in this Annual Report), our bond indentures and other agreements governing our indebtedness contain certain restrictive financial and operating covenants, including covenants that restrict our ability to complete acquisitions, pay cash dividends, incur indebtedness, make investments, sell assets and take 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 bond indentures or other agreements governing our indebtedness. The Credit Agreement requires that we satisfy a fixed charge coverage ratio, a net total lease adjusted leverage ratio and a net secured debt lease adjusted leverage ratio on a quarterly basis and our bond indentures require that, among other things, we satisfy a leverage ratio (not lease adjusted) or a fixed charge coverage ratio (not lease adjusted), as a condition to taking actions such as paying dividends and incurring indebtedness.
The Credit Agreement uses EBITDAR-based calculations and the bond indentures use EBITDA-based calculations as the primary measures of financial performance includingfor purposes of calculating leverage and fixed charge coverage ratios. The bond indenture EBITDA-based calculations include our consolidated subsidiaries, other than those we have designated as “Unrestricted Subsidiaries” as defined in the bond indentures. Generally, the Credit Agreement and the bond indentures use a trailing four fiscal quarter basis for purposes of the relevant calculations and require certain adjustments and exclusions for purposes of those calculations, which make the calculation of financial performance for purposes of those calculations under the Credit Agreement and bond indentures not directly comparable to Adjusted EBITDA as presented herein. These adjustments can be significant. For example, the calculation of financial performance under the Credit Agreement and certain of our bond indentures includes (subject to specified exceptions and caps) adjustments for non-cash charges and for expected benefits associated with (i) completed acquisitions, (ii) certain executed lease agreements associated with our data center business that have yet to commence, and (iii) restructuring and other strategic initiatives, such as Project Summit. The calculation of financial performance under our other bond indentures includes, for example, adjustments for non-cash charges and for expected benefits associated with (i) completed acquisitions, and (ii) events that are extraordinary, unusual or non-recurring, such as the COVID-19 pandemic.
Our leverage and fixed charge coverage ratios under the 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 20172020 are as follows:
 December 31, 2016 December 31, 2017 Maximum/Minimum Allowable
Net total lease adjusted leverage ratio5.7
 5.0
 Maximum allowable of 6.5(1)(2)
Net secured debt lease adjusted leverage ratio2.7

 Maximum allowable of 4.0
Bond leverage ratio (not lease adjusted)5.2

 Maximum allowable of 6.5-7.0(3)(4)
Fixed charge coverage ratio2.4
 2.1
 Minimum allowable of 1.5

(1)Our maximum allowable netDECEMBER 31, 2020MAXIMUM/MINIMUM 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%5.3Maximum allowable 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 total6.5
Net secured debt lease adjusted leverage ratio exceeded 6.0 as measured as1.9Maximum allowable of the end4.0
Fixed charge coverage ratio2.3Minimum allowable 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 adjusted1.5
Bond leverage ratio under the Credit Agreement is 6.5.

(not lease adjusted)5.9
Maximum allowable of 7.0(1)
(2)Bond fixed charge coverage ratio (not lease adjusted)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)3.2
The maximumMinimum 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.of 2.0(1)

(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.


(1)The maximum allowable leverage ratio under our indentures for the GBP Notes due 2025, the 47/8% Notes due 2027, the 51/4% Notes due 2028 and the 47/8% Notes due 2029 is 7.0. As of December 31, 2020, we no longer have any indentures subject to a maximum leverage ratio of 6.5. The indentures for the 5% Notes, the 51/4% Notes due 2030, the 41/2% Notes and the 55/8% Notes do not include a maximum leverage ratio covenant; the indentures for these notes instead require us to maintain a minimum fixed charge coverage ratio of 2.0. In certain instances as provided in our indentures, we have the ability to incur additional indebtedness that would result in our bond leverage ratio or bond fixed charge coverage ratio exceeding or falling below the maximum or minimum permitted ratio under our indentures and still remain in compliance with the applicable covenant.
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.

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.


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.

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

DERIVATIVE INSTRUMENTS
INTEREST RATE SWAP AGREEMENTS
In OctoberMarch 2018, we entered into interest rate swap agreements to limit our exposure to changes in interest rates on a portion of our floating rate indebtedness. As of December 31, 2020, we had $350.0 million in notional value of interest rate swap agreements outstanding, which expire in March 2022. Under the interest rate swap agreements, we receive variable rate interest payments associated with the notional amount of each interest rate swap, based upon one-month LIBOR, in exchange for the payment of fixed interest rates as specified in the interest rate swap agreements.
In July 2019, we entered into forward-starting interest rate swap agreements to limit our exposure to changes in interest rates on a portion of our floating rate indebtedness once our current interest rate swap agreements expire in March 2022. The forward-starting interest rate swap agreements have $350.0 million in notional value, commence in March 2022 and expire in March 2024. Under the swap agreements, we will receive variable rate interest payments based upon one-month LIBOR, in exchange for the payment of fixed interest rates as specified in the interest rate swap agreements.
We have designated these interest rate swap agreements, including the forward-starting interest rate swap agreements, as cash flow hedges.
CROSS-CURRENCY SWAP AGREEMENTS
We enter into cross-currency swap agreements to hedge the variability of exchange rate impacts between the United States dollar and the Euro. The cross-currency swap agreements are designated as a hedge of net investment against certain of our Euro denominated subsidiaries and require an exchange of the notional amounts at maturity.
In August 2019, we entered into cross-currency swap agreements whereby we notionally exchanged approximately $110.0 million at an interest rate of 6.0% for approximately 99.1 million Euros at a weighted average interest rate of approximately 3.65%. These cross-currency swap agreements expire in August 2023.
In September 2020, we entered into cross-currency swap agreements whereby we notionally exchanged approximately $359.2 million at an interest rate of 4.5% for approximately 300.0 million Euros at a weighted average interest rate of approximately 3.4%. These cross-currency swap agreements expire in February 2026.
See Note 5 to Notes to Consolidated Financial Statements included in this Annual Report for additional information on our derivative instruments.
EQUITY FINANCING
In 2017, we entered into thea 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, which may include acquisitions and investments, including financing the expansion ofacquisitions and investments in our data center business and adjacent businesses through acquisitions,Global Data Center Business, and repaying amounts outstanding from time to time under the Revolving Credit Facility.

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,consolidated financial statements from 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.OSG Acquisition.
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).GLENBEIGH ACQUISITION
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.

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.

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.

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 haveand state net operating loss carryforwards which expire from 2018 through 2036, of which we are expecting an insignificant state tax benefit is expected to be realized. We have assets for foreign net operating losses of $103.6$92.1 million, with various expiration dates (and in some cases no expiration date), subject to a valuation allowance of approximately 59%43%.

Table 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.Contents

ITEM 7A. Quantitative and Qualitative Disclosures About Market Risk.QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.
Credit RiskCREDIT 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, 20172020 relate to cash and cash equivalents held on depositin money market funds with seven global banks and 12 "Triple A"four “Triple A” rated money market funds all of which we consider to be large, highly-rated investment-grade institutions.and time deposits with one global bank. As per our risk management investment policy, we limit exposure to concentration of credit risk by limiting the amount invested in any one mutual fund to a maximum of $50.0 million1% of the fund's total assets or in any one financial institution to a maximum of $75.0 million. As of December 31, 2017,2020, our cash and cash equivalents balance, including restricted cash, was $925.7 million, which included money market funds amounting to $585.0 million and time deposits amounting to $24.5$205.1 million.
Interest Rate RiskINTEREST 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, 2017,2020, we had $1,354.5$1,108.1 million of variable rate debt outstanding with a weighted average variable interest rate of approximately 4.4%3.1%, and $5,775.0$7,689.3 million of fixed rate debt outstanding. As of December 31, 2017,2020, approximately 81%87% 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, 20172020 would have been reduced by approximately $15.0$13.8 million.
See Note 45 to Notes to Consolidated Financial Statements included in this Annual Report for a discussion on our interest rate swaps and Note 6 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, 2017.2020.
Currency RiskCURRENCY 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.

We have adopted and implemented a number of strategies to mitigate the risks associated with fluctuations in foreign currency exchange rates. One strategy is to finance certain of our international subsidiaries with debt that is denominated in local currencies, thereby providing a natural hedge. In determining the amount of any such financing, we take into account local tax considerations, among other factors. Another strategy we utilize is for IMI or IMIM, a wholly-owned subsidiary of IMI, to borrow in foreign currencies to hedge our intercompany financing activities. In addition, on occasion, we enter into currency swaps to temporarily or permanently hedge an overseas investment, such as a major acquisition, to lock in certain transaction economics. We have implemented these strategies for our foreign investments in the United Kingdom, Canada, Australia, Latin America and continental Europe. IM UK has financed a portion of its capital needs through the issuance in British pounds sterling of the GBP Notes due 2025. Our Australian business has financed a portion of its capital needs through direct borrowings in Australian dollars under the AUD Term Loan. 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,
Prior to their redemption in August 2020, we had designated a portion of theour previously outstanding 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$17.0 million ($15.017.0 million net of tax) of foreign exchange losses related to the "marking-to-market"“marking-to-market” of such debt to currency translation adjustments which is a component of accumulatedAccumulated other comprehensive items, net included in stockholders' equityour Consolidated Balance Sheet for the year ended December 31, 2017.2020.

Unrealized gains are recognized as assets, which are recorded as a component of Other within Other assets, net, while unrecognized losses are recognized as liabilities, which are recorded as a component of Other long-term liabilities in our Consolidated Balance Sheets.
See Note 5 to Notes to Consolidated Financial Statements included in this Annual Report for a discussion on our cross-currency swap agreements.
As of and during the year ending December 31, 2017,2020, we had no 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.contracts. At the maturity of any forward contract, we may enter into a new forward contract to hedge movements in the underlying currencies. At the time of settlement, we either pay or receive the net settlement amount from any forward contract and recognize this amount in otherOther 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. WeHistorically, 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“Accumulated Other Comprehensive Items, net"net” component of equity. A 10% depreciation in year-end 20172020 functional currencies, relative to the United States dollar, would result in a reduction in our equity of approximately $241.5$286.5 million.

As previously disclosed in our Quarterly Reports on Form 10-Q for the quarters ended March 31, 2020 and June 30, 2020 (the “2020 Quarterly Reports”), during the first quarter of 2020, we determined that one of our non-U.S. subsidiaries provided limited hard copy record, electronic media (e.g., CD), box and container storage and handling services during such quarter, and in prior periods since the reporting requirement took effect, to at least one Government of Iran entity and one entity designated under Executive Order No. 13382 - both located outside of Iran. In each case, the customer relationship commenced at a time when U.S. sanctions law did not limit dealings with entities determined to be part of the Government of Iran or designated under Executive Order No. 13382 by non-U.S. entities owned or controlled by U.S. persons. Each relationship automatically continued from year to year without any affirmative step being taken by either party.
We also reported in the 2020 Quarterly Reports that we had notified the U.S. Department of the Treasury’s Office of Foreign Assets Control (“OFAC”) of these limited activities and initiated an internal investigation, and, during that investigation, we had identified two additional customer relationships between the subsidiary in question and entities designated under Executive Order No. 13382 and Executive Order No. 13224, neither of which was active and ongoing during the year ended December 31, 2020. We have been actively cooperating with OFAC in its review of this matter.
During the second quarter of 2020, the subsidiary in question notified both entities with active relationships identified during the first quarter of 2020 of its decision to terminate those relationships. Because we consider property held in storage for these two entities to be blocked property under regulations administered by OFAC, the subsidiary in question continues to hold the boxes and will do so in accordance with applicable rules and regulations. Following termination of the relationships, the subsidiary in question received cash of less than 2,000 British pounds sterling from one of the entities for services provided and invoiced prior to the termination. The subsidiary is treating this money as blocked property. The subsidiary has not engaged in any other activity with the entities during the period covered by this report. Consistent with the disclosure contained in the 2020 Quarterly Reports, we do not intend to continue any activity involving the entities in question.
The gross revenues attributable to the services provided to these entities while the entities were designated under Executive Order No. 13382 and Executive Order No. 13224 were less than 30,000 British pounds sterling in the aggregate. It is not possible to determine the exact amount of profits attributable to these services, but the net profits are less than the associated revenues.
Following the year ended December 31, 2020, we submitted a Final Notice of Voluntary Disclosure (“Final VSD”) with OFAC on January 14, 2021. The Final VSD included a detailed overview of our internal investigation and the remedial measures we have implemented or will be implementing to address the root causes of the potentially violative activity. The Final VSD findings showed that the potential violations were inadvertent. We will continue to cooperate fully with OFAC in its ongoing review of this matter.
We continue to enhance our internal processes and procedures designed to identify transactions associated with restricted parties, such as introducing a Global International Sanctions and Trade Law Policy and engaging a more comprehensive third-party screening provider. We are also supplementing our existing compliance training with the launch of global training on sanctions and restricted parties in the first quarter of 2021. We will continue to review and improve our programs and processes, as necessary or appropriate, to comply with all applicable sanctions laws and to comply with the disclosure requirements of Section 13(r) of the Exchange Act.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the shareholders and the Board of Directors of Iron Mountain Incorporated
Boston, MassachusettsOPINION ON THE FINANCIAL STATEMENTS

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Iron Mountain Incorporated and subsidiaries (the "Company"“Company”) as of December 31, 20172020 and 2016,2019, 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, 2017,2020, and the related notes and the schedule listed in the Index at Item 15 (collectively referred to as the "financial statements"“financial statements”).In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 20172020 and 2016,2019, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2017,2020, 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'sCompany’s internal control over financial reporting as of December 31, 2017,2020, 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, 2018,24, 2021, expressed an unqualified opinion on the Company'sCompany’s internal control over financial reporting.

Basis for Opinion

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

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

CRITICAL AUDIT MATTER

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

Part IV
GOODWILL - GLOBAL DATA CENTER REPORTING UNIT - REFER TO NOTE 2.K. TO THE FINANCIAL STATEMENTS
CRITICAL AUDIT MATTER DESCRIPTION
The Company’s evaluation of goodwill for impairment involves the comparison of the fair value of each reporting unit to its carrying value. The Company determined the fair value of the Global Data Center reporting unit using a combined approach based on the present value of future cash flows (the “Discounted Cash Flow Model”) and market multiples (the “Market Approach”). The determination of the fair value using the Discounted Cash Flow Model requires management to make significant assumptions related to future revenue growth rates, operating margins, discount rates and capital expenditures. The determination of the fair value using the Market Approach requires management to make significant assumptions related to adjusted earnings before interest, taxes, depreciation and amortization (“Adjusted EBITDA”) multiples. Changes in economic and operating conditions impacting these assumptions or changes in multiples could result in goodwill impairments in future periods. The goodwill balance allocated to the Global Data Center reporting unit was $431 million as of October 1, 2020 (goodwill impairment testing date). The fair value of the Global Data Center reporting unit exceeded its carrying value as of the measurement date and, therefore, no impairment was recognized.
The Global Data Center reporting unit’s fair value exceeded its carrying value by less than 10%, accordingly, auditing the assumptions used in the goodwill impairment analysis for this reporting unit involved especially subjective judgment.
HOW THE CRITICAL AUDIT MATTER WAS ADDRESSED IN THE AUDIT
Our audit procedures related to future revenue growth rates, operating margins and capital expenditures (collectively, the “Forecast”), Adjusted EBITDA multiples and the selection of discount rates for the Global Data Center reporting unit included the following, among others:
We tested the effectiveness of controls over the evaluation of goodwill for impairment, including those over the Forecast and the selection of the Adjusted EBITDA multiples and discount rates.
We evaluated management’s ability to accurately forecast by comparing actual results to management’s historical forecasts.
We evaluated the reasonableness of management’s Forecast by comparing it to (1) historical results, (2) internal communications to management and the Board of Directors, and (3) forecasted information included in Company press releases and industry reports of the Company and companies in its peer group.
With the assistance of our fair value specialists, we evaluated the Adjusted EBITDA multiples, including testing the underlying source information and mathematical accuracy of the calculations and comparing the multiples selected by management to its guideline companies.
With the assistance of our fair value specialists, we evaluated the discount rates, including testing the underlying source information and the mathematical accuracy of the calculations, and developing a range of independent estimates and comparing those to the discount rates selected by management.

IRON MOUNTAIN INCORPORATED
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
DECEMBER 31, 20172020
(In thousands, except share and per share data)

1. Nature of BusinessNATURE OF BUSINESS
The accompanying financial statements represent the consolidated accounts of Iron Mountain Incorporated, a Delaware corporation ("IMI"(“IMI”), and its subsidiaries ("we"(“we” or "us"“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 Africaaround the world protect their information, lowerreduce storage rental costs, comply with regulations, facilitate corporate disaster recovery, and better use their information and information technology ("IT"(“IT”) infrastructure for business advantages, regardless of its format, location or life cycle stage. We currentlydo this by storing physical records and data backup media, offering information management solutions, and providing data center space for enterprise-class colocation and opportunistic hyperscale deployments. We offer comprehensive records and information management services and data management services, along with the expertise and experience to address complex storage and information management challenges such as rising storage rental costs, legal and regulatory compliance, and disaster recovery requirements. We provide secure and reliable data center facilities to protect digital information and ensure the continued operation of our customers’ IT infrastructure, with reliable and flexible deployment options.
In March 2020, the World Health Organization declared a novel strain of coronavirus (“COVID-19”) a pandemic. This resulted in U.S. federal, state and local and foreign governments and private entities mandating various restrictions, including travel restrictions, restrictions on public gatherings and stay-at-home orders and advisories. In response, we temporarily closed certain of our offices and facilities across the world and implemented certain travel restrictions for our employees. The preventative and protective actions that governments have ordered, or we or our customers have implemented, have resulted in a period of reduced service operations and business disruption for us, our customers and other third parties with which we do business. Currently, certain of the restrictions have been lifted; however, other restrictions still remain and the broader impacts of the COVID-19 pandemic on our financial position, results of operations and cash flows, including impacts to the estimates we use in the preparation of our financial statements, remain uncertain and difficult to predict as information continues to evolve, and the severity and duration of the pandemic remains unknown, as is our visibility of its effect on the markets we serve and our customers across an arraywithin those markets.
In October 2019, we announced a global program designed to better position us for future growth and achievement of market verticals - commercial, legal, financial, healthcare, insurance, life sciences, energy, business services, entertainmentour strategic objectives (“Project Summit”).

a.    Principles of ConsolidationA. 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 EstimatesB. USE OF ESTIMATES
The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America ("GAAP"(“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 EquivalentsC. FOREIGN CURRENCY
Local currencies are the functional currencies for our operations outside the United States, with the exception of certain foreign holding companies, whose functional currency is the United States dollar. In those instances where the local currency is the functional currency, assets and Restricted Cashliabilities are translated at period-end exchange rates, and revenues and expenses are translated at average exchange rates for the applicable period.

D. CASH, CASH EQUIVALENTS AND RESTRICTED CASH
Cash and cash equivalents include cash on hand and cash invested in highly liquid short-term securities, which have remaining maturities at the date of purchase of less than 90 days. Cash and cash equivalents are carried at cost, which approximates fair value.
At December 31, 2017, we had approximately $22,167
E. ALLOWANCE FOR DOUBTFUL ACCOUNTS AND CREDIT MEMO RESERVES
We maintain an allowance for doubtful accounts and a credit memo reserve for estimated losses resulting from the potential inability of restricted cash held by certain financial institutions relatedour customers to bank guarantees. We adoptedmake required payments and potential disputes regarding billing and service issues.
In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update ("ASU") No. 2016-18, Statement2016-13, Financial Instruments-Credit Losses-Measurement of Cash Flows (Topic 230): Restricted Cash ("Credit Losses on Financial Instruments (“ASU 2016-18"2016-13”), which is discussed. ASU 2016-13 changes how entities will measure credit losses on most financial assets. The standard eliminates the probable initial recognition of estimated losses and provides a forward-looking expected credit loss model for accounts receivable, loans and other financial instruments.
On January 1, 2020 we adopted ASU 2016-13 on a modified retrospective basis for all financial assets measured at amortized cost. The adoption of ASU 2016-13 did not result in greater detaila material impact on our consolidated financial statements. Under ASU 2016-13, we calculate and monitor our allowance considering future potential economic and macroeconomic conditions and reasonable and supportable forecasts for expected future collectability of our outstanding receivables, in Note 2.w.,addition to considering our past loss experience, current and prior trends in our aged receivables and credit memo activity. Our considerations when calculating our allowance include, but are not limited to, the following: the location of our businesses, the composition of our customer base, our product and service lines, potential future economic unrest, and potential future macroeconomic factors, including natural disasters and any impacts associated with the COVID-19 pandemic. Continued adjustments will be made should there be any material change to reasonable and supportable forecasts that may impact our likelihood of collection, as it becomes evident. Our highly diverse global customer base, with no single customer accounting for more than 1% of revenue during the fourth quarter of 2017. Our consolidated statement of cash flows for the years ended December 31, 2015, 20162020, 2019 and 2017 reflect2018, limits our exposure to concentration of credit risk. Additionally, we write off uncollectible balances as circumstances warrant, generally, no later than one year past due.
Prior to our adoption of ASU 2016-18.2016-13, we maintained an allowance for doubtful accounts for estimated losses resulting from the potential inability of our customers to make required payments and potential disputes regarding billing and service issues. When calculating the allowance, we considered our past loss experience, current and prior trends in our aged receivables and credit memo activity, current economic conditions, and specific circumstances of individual receivable balances. If the financial condition of our customers were to significantly change, resulting in a significant improvement or impairment of their ability to make payments, an adjustment of the allowance might have been required.

F. CONCENTRATIONS OF CREDIT RISK
Financial instruments that potentially subject us to credit risk consist principally of Significant Accounting Policies (Continued)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, 2020 and 2019 related to cash and cash equivalents. At December 31, 2020, we had money market funds with 4 “Triple A” rated money market funds and time deposits with 1 global bank. At December 31, 2019, we had money market funds with 7 “Triple A” rated money market funds. As per our risk management investment policy, we limit exposure to concentration of credit risk by limiting the amount invested in any one mutual fund to a maximum of 1% of the fund's total assets or in any one financial institution to a maximum of $75,000. See Note 2.o.
G. PREPAID EXPENSES AND ACCRUED EXPENSES
There are no prepaid expenses with items greater than 5% of total current assets as of December 31, 2020 and 2019.

Minor maintenance costs are expensed as incurred. Major improvements which extend the life, increase the capacity or improve the safety or the efficiency of property owned are capitalized and depreciated. Major improvements to leased buildings are capitalized as leasehold improvements and depreciated.
We capitalize interest expense during the active construction period of major capital projects. Capitalized interest is added to the cost of the underlying assets and is amortized over the useful lives of the assets. During the years ended December 31, 2020, 2019 and 2018, capitalized interest is as follows:
YEAR ENDED DECEMBER 31,
202020192018
Capitalized interest$14,321 $15,980 $3,732 
We develop various software applications for internal use. Computer software costs associated with internal use software are expensed as incurred until certain capitalization criteria are met. Third party consulting costs, as well as payroll and related costs for employees directly associated with, and devoting time to, the development of internal use computer software projects (to the extent time is spent directly on the project) are capitalized. Capitalization begins when the design stage of the application has been completed and it is probable that the project will be completed and used to perform the function intended. Capitalization ends when the asset is ready for its intended use. Depreciation begins when the software is placed in service. Computer software costs that are capitalized are periodically evaluated for impairment.
During the years ended December 31, 2020, 2019 and 2018, capitalized costs associated with the development of internal use computer software projects are as follows:

Entities are required to record the fair value of a liability for an asset retirement obligation in the period in which it is incurred. Asset retirement obligations represent the costs to replace or remove tangible long-lived assets required by law, regulatory rule or contractual agreement. Our asset retirement obligations are primarily the result of requirements under our facility lease agreements which generally have “return to original condition” clauses which would require us to remove or restore items such as shred pits, vaults, demising walls and office build-outs, among others. The significant assumptions used in estimating our aggregate asset retirement obligations are the functional currenciestiming of removals, the probability of a requirement to perform, estimated cost and associated expected inflation rates that are consistent with historical rates and credit-adjusted risk-free rates that approximate our incremental borrowing rate. Our asset retirement obligations at December 31, 2020 and 2019 were $34,537 and $30,831, respectively.

I. LEASES
We lease facilities for certain warehouses, data centers and office space. We also have land leases, including those on which certain facilities are located. The majority of our operations outsideleased facilities are classified as operating leases that, on average, have initial lease terms of five to 10 years, with 1 or more lease renewal options to extend the United States,lease term. Our lease renewal option terms generally range from one to five years. The exercise of the lease renewal option is at our sole discretion and may contain fixed rent, fair market value based rent or Consumer Price Index rent escalation clauses. We include option periods in the lease term when our failure to renew the lease would result in an economic disincentive, thereby making it reasonably certain that we will renew the lease. We recognize straight line rental expense over the life of the lease and any fair market value or Consumer Price Index rent escalations are recognized as variable lease expense in the period in which the obligation is incurred. In addition, we lease certain vehicles and equipment. Vehicle and equipment leases typically have lease terms ranging from one to seven years.
We account for all leases, both operating and financing, in accordance with ASU No. 2016-02 Leases (Topic 842), as amended ("ASU 2016-02") which we adopted on January 1, 2019 on a modified retrospective basis. We also adopted an accounting policy which provides that leases with an initial term of 12 months or less will not be included within the lease right-of-use assets and lease liabilities recognized on our Consolidated Balance Sheets after the adoption of ASU 2016-02. We will continue to recognize the lease payments for those leases with an initial term of 12 months or less in our Consolidated Statements of Operations on a straight-line basis over the lease term.
The lease right-of-use assets and related lease liabilities are classified as either operating or financing. Lease right-of-use assets are calculated as the net present value of future payments plus any capitalized initial direct costs less any tenant improvements or lease incentives. Lease liabilities are calculated as the net present value of future payments. In calculating the present value of the lease payments, we utilize the rate stated in the lease (in the limited circumstances when such rate is explicitly stated) or, if no rate is explicitly stated, we utilize a rate that reflects our securitized incremental borrowing rate by geography for the lease term. We account for nonlease components (which include common area maintenance, taxes, and insurance) with the related lease component. Any variable nonlease components are not included within the lease right-of-use asset and lease liability on our Consolidated Balance Sheets, and instead, are reflected as an expense in the period incurred.
At January 1, 2019, we recognized the cumulative effect of initially applying ASU 2016-02 as an adjustment to the opening balance of (Distributions in excess of earnings) Earnings in excess of distributions, resulting in an increase of approximately $5,800 to stockholders’ equity due to certain build to suit leases that were accounted for as financing leases under Accounting Standards Codification (“ASC”) 840, Leases (“ASC 840”) but are accounted for as operating leases under ASU 2016-02.

J. 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 sum of the forecasted undiscounted net cash flows of the operation to which the assets relate to their carrying amount. The operations are reflectedgenerally 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 accumulated other comprehensive, net componentslives over which long-lived assets, including finite-lived intangible assets, are amortized is necessary.

K. GOODWILL AND OTHER INDEFINITE-LIVED INTANGIBLE ASSETS
Goodwill and intangible assets with indefinite lives are not amortized but are reviewed annually for impairment or loss on foreign currency transactions, calculated as the difference between the historical exchange ratemore frequently if impairment indicators arise. Other than goodwill, we currently have no intangible assets that have indefinite lives 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,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, 2020, 2019 and 2018. We concluded that as of October 1, 2020, 2019 and 2018, goodwill was not impaired. During the first quarter of 2020, as discussed in greater detail below, we concluded that we had a triggering event related to our Fine Arts reporting unit, requiring us to perform an interim goodwill impairment test. We concluded that the fair value of our Fine Arts reporting unit was less than its carrying value, and, therefore, we recorded a $23,000 impairment charge on the goodwill associated with this reporting unit during the first quarter of 2020.
The following is a discussion regarding (i) the reporting units at which level we tested goodwill for impairment as of October 1, 2019, (ii) changes to the composition of our reporting units between October 1, 2019 and December 31, 2019, (iii) interim goodwill impairment review for our Fine Arts reporting unit during the first quarter of 2020 and (iv) the reporting units at which level we tested goodwill for impairment as of October 1, 2020 and the composition of these reporting units at December 31, 2020 (including the amount of goodwill associated with each reporting unit). When changes occur in the composition of one or more reporting units, the goodwill is reassigned to the reporting units affected based upon their relative fair values.
GOODWILL IMPAIRMENT ANALYSIS - 2019
I. REPORTING UNITS AS OF OCTOBER 1, 2019
Our reporting units at which level we performed our goodwill impairment analysis as of October 1, 2019 were as follows:
North American Records and Information Management
North American Data Management
Fine Arts
Entertainment Services
Western Europe
Northern/Eastern Europe and Middle East and India (“NEE and MEI”)
Latin America

Australia, New Zealand and South Africa (“ANZ SA”)
Asia
Global Data Center
We concluded that the goodwill associated with each of our reporting units was not impaired as of such date.
II.CHANGES TO COMPOSITION OF REPORTING UNITS BETWEEN OCTOBER 1, 2019 AND DECEMBER 31, 2019
During the fourth quarter of 2019, as a result of the realignment of our global managerial structure and changes to our internal financial reporting associated with Project Summit, we reassessed the composition of our reportable operating segments (see Note 10 for a description and definitions of our reporting operating segments) as well as our reporting units.
We noted the following changes to our reporting units:
our former North American Records and Information Management (excluding our technology escrow services business) and North American Data Management reporting units are now being managed as our “North America RIM” reporting unit;
our former Western Europe and NEE and MEI reporting units (excluding India) and our business in Africa, which was previously managed as a component of our former ANZ SA reporting unit, is now being managed together as our “Europe RIM” reporting unit;
our business in India, which was previously managed as a component of our former NEE and MEI reporting unit, is now being managed in conjunction with our businesses in Asia as our “Asia RIM” reporting unit;
our former ANZ SA reporting unit will no longer include South Africa and will be referred to as our “Australia and New Zealand RIM” (“ANZ RIM”) reporting unit; and
our technology escrow services business is now being managed separately as our “Technology Escrow Services” reporting unit.

GOODWILL IMPAIRMENT ANALYSIS - 2020
I. INTERIM GOODWILL IMPAIRMENT REVIEW - FINE ARTS
During the first quarter of 2020, we concluded that we had a triggering event related to our Fine Arts reporting unit, requiring us to perform an interim goodwill impairment test. The primary factor contributing to our conclusion was the expected impact of the COVID-19 pandemic to this particular business and its customers and revenue sources, which caused us to believe it was more likely than not that the carrying value of our Fine Arts reporting unit exceeded its fair value. During the first quarter of 2020, we performed an interim goodwill impairment test for our Fine Arts reporting unit utilizing a discounted cash flow model, with updated assumptions on future revenues, operating expenditures and capital expenditures. We concluded that the fair value of our Fine Arts reporting unit was less than its carrying value, and, therefore, we recorded a $23,000 impairment charge on the goodwill associated with this reporting unit during the first quarter of 2020. Factors that may impact these assumptions include, but are not limited to: (i) our ability to maintain, or grow, storage and retail service revenues in this reporting unit in line with current expectations and (ii) our ability to manage our fixed and variable costs in this reporting unit in line with potential future revenue declines.
II. REPORTING UNITS AS OF OCTOBER 1, 2020
Our reporting units at which level we performed our goodwill impairment analysis as of October 1, 2020 were as follows:
North America RIM
Europe RIM
Latin America RIM
ANZ RIM
Asia RIM
Global Data Center
Fine Arts
Entertainment Services
Technology Escrow Services
We concluded that the goodwill associated with each of our reporting units was not impaired as of such date. There were no changes to the composition of our reporting units between October 1, 2020 and December 31, 2020.

Reporting unit valuations have generally been determined using a combined approach based on the present value of future cash flows (the “Discounted Cash Flow Model”) and market multiples (the “Market Approach”).
The Discounted Cash Flow Model incorporates significant assumptions including future revenue growth rates, operating margins, discount rates and capital expenditures.
The Market Approach requires us to make assumptions related to Adjusted EBITDA (as defined in Note 10) multiples.
Changes in economic and operating conditions impacting these assumptions or changes in multiples could result in goodwill impairments in future periods. In conjunction with our annual goodwill impairment reviews, we reconcile the sum of the valuations of all of our reporting units to our market capitalization as of such dates.

L. FINITE-LIVED INTANGIBLE ASSETS AND LIABILITIES
I. CUSTOMER RELATIONSHIP INTANGIBLE ASSETS
Customer relationship intangible assets, which are acquired through either business combinations or acquisitions of customer relationships, are amortized over periods ranging from 10 to 30 years. Customer relationship intangible assets are recorded based upon estimates of their fair value.
II. CUSTOMER INDUCEMENTS
Payments that are made to a customer’s current records management vendor in order to terminate the customer’s existing contract with that vendor (“Permanent Withdrawal Fees”), or direct payments to a customer for which no distinct benefit is received in return, are collectively referred to as "Customer Inducements". Customer Inducements are treated as a reduction of the transaction price over periods ranging from one to 10 years and are included in Other expense (income), net,storage and service revenue in the accompanying Consolidated Statements of Operations. If the customer terminates its relationship with us, the unamortized carrying value of the Customer Inducement intangible asset is charged to revenue. However, in the event of such termination, we generally collect, and record as income, permanent removal fees that generally equal or exceed the amount of the unamortized Customer Inducement intangible asset.
III. DATA CENTER INTANGIBLE ASSETS AND LIABILITIES
Finite-lived intangible assets associated with our Global Data Center Business consist of the following:
DATA CENTER IN-PLACE LEASE INTANGIBLE ASSETS AND DATA CENTER TENANT RELATIONSHIP INTANGIBLE ASSETS
Data Center In-Place Lease Intangible Assets (“Data Center In-Place Leases”) and Data Center Tenant Relationship Intangible Assets (“Data Center Tenant Relationships”) reflect the value associated with acquiring a data center operation with active tenants as of the date of acquisition. The value of Data Center In-Place Leases is determined based upon an estimate of the economic costs (such as lost revenues, tenant improvement costs, commissions, legal expenses and other costs to acquire new data center leases) avoided by acquiring a data center operation with active tenants that would have otherwise been incurred if the data center operation was purchased vacant. Data Center In-Place Leases are amortized over the weighted average remaining term of the acquired data center leases. The value of Data Center Tenant Relationships is determined based upon an estimate of the economic costs avoided upon lease renewal of the acquired tenants, based upon expectations of lease renewal. Data Center Tenant Relationships are amortized over the weighted average remaining anticipated life of the relationship with the acquired tenant.
DATA CENTER ABOVE-MARKET AND BELOW-MARKET IN-PLACE LEASE INTANGIBLE ASSETS
We record Data Center Above-Market In-Place Lease Intangible Assets (“Data Center Above-Market Leases”) and Data Center Below-Market In-Place Lease Intangible Assets (“Data Center Below-Market Leases”) at the net present value of the difference between (i) the contractual amounts to be paid pursuant to each in-place lease and (ii) management’s estimate of the fair market lease rates for each corresponding in-place lease. Data Center Above-Market Leases and Data Center Below-Market Leases are amortized over the remaining non-cancellable term of the acquired in-place lease to storage revenue.

M. DEFERRED FINANCING COSTS
Deferred financing costs are amortized over the life of the related debt. If debt is retired early, the related unamortized deferred financing costs are written-off in the period the debt is retired to Other expense (income), net. See Note 6.
N. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES
Every derivative instrument is required to be recorded in the balance sheet as either an asset or a liability measured at its fair value. Periodically, we acquire derivative instruments that are intended to hedge either cash flows or values that are subject to foreign exchange or other market price risk and not for trading purposes. We have formally documented our hedging relationships, including identification of the hedging instruments and the hedged items, as well as our risk management objectives and strategies for undertaking each hedge transaction. Given the recurring nature of our revenues and the long-term nature of our asset base, we have the ability and the preference to use long-term, fixed interest rate debt to finance our business, thereby preserving our long-term returns on invested capital. We 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 enter into cross-currency swaps to hedge the variability of exchange rates between the United States and our foreign subsidiaries, as well as interest rates. We may also use borrowings in foreign currencies, either obtained in the United States or by our foreign subsidiaries, to hedge foreign currency risk associated with our international investments. 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, 2017,2020 and 2019, none of our derivative instruments contained credit-risk related contingent features. See Note 3.

Property, plant and equipment are stated at cost and depreciated using the straight-line method with the following useful lives (in years):
Range
Buildings and building improvements5 to 40
Leasehold improvements5 to 10 or life of the lease (whichever is shorter)

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.

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:

 $27,757

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, 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.

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.

(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.
Estimated amortization expense for deferred financing costs, which are amortized as a component of interest expense, is as follows:

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.

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 $0.10 per basic and diluted share), respectively.

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:
 December 31, 2017
 Stock Options Outstanding % of
Stock Options Outstanding
Three-year vesting period (10 year contractual life)3,285,529
 89.5%
Five-year vesting period (10 year contractual life)386,211
 10.5%
 3,671,740
 100.0%
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.

2. Summary of Significant Accounting Policies (Continued)

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:
Weighted Average Assumptions 2015 2016 2017
Expected volatility 28.4% 27.2% 25.7%
Risk-free interest rate 1.70% 1.32% 1.96%
Expected dividend yield 5% 7% 6%
Expected life 5.4 years
 5.6 years
 5.0 years
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.

Restricted Stock Units
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.
The fair value of earned PUs that vested during the years ended December 31, 2015, 2016 and 2017, is as follows:

Employee Stock Purchase Plan
We offer an ESPP in which participation is available to substantially all United States and Canadian employees who meet certain service eligibility requirements. The ESPP provides 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:

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 MeasurementsO. FAIR VALUE MEASUREMENTS
Entities are permitted under GAAP to elect to measure manycertain financial instruments and certain other items at either fair value or cost. We have elected the cost measurement option in all circumstances where we had an option.
Our financial assets or liabilities that are carried at fair value are required to be measured using inputs from the three levels of the fair value hierarchy. A financial asset or liability'sliability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement.
The three levels of the fair value hierarchy are as follows:
Level 1—Inputs are unadjusted quoted prices in active markets for identical assets or liabilities that we have the ability to access at the measurement date.

Level 2—Inputs include quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (i.e., interest rates, yield curves, etc.), and inputs that are derived principally from or corroborated by observable market data by correlation or other means (market corroborated inputs).
Level 3—Unobservable inputs that reflect our assumptions about the assumptions that market participants would use in pricing the asset or liability.
The assets and liabilities carried at fair value and measured on a recurring basis as of December 31, 20162020 and 2017,2019, respectively, are as follows:

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.

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.

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

P. REDEEMABLE NONCONTROLLING INTERESTS
Certain unaffiliated third parties own noncontrolling interests in certain of our foreign consolidated subsidiaries in Chile, India and South Africa.subsidiaries. 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'stockholders’ equity. Redeemable noncontrolling interests are reported at the higher of their redemption value or the noncontrolling interest holders'holders’ proportionate share of the underlying subsidiaries net carrying value. Increases or decreases in the redemption value of the noncontrolling interest are offset against Additional Paid-in Capital.


In 2018, one of our noncontrolling interest shareholders exercised its option to put its ownership interest back to us. Upon the exercise of the put option, this noncontrolling interest became mandatorily redeemable by us, and, therefore, is accounted for as a liability rather than a component of redeemable noncontrolling interests. Subject to agreement on final settlement terms and conditions, we and this noncontrolling interest shareholder have agreed in principle on the put option price for the noncontrolling interest shares. We are in dispute with this noncontrolling interest shareholder with respect to whether interest from the date of the put and certain other costs should be reimbursable to the noncontrolling interest shareholder. We intend to vigorously defend that interest and certain other reimbursable costs are not owed to the noncontrolling interest shareholder. We have recorded our estimate of the fair value of these noncontrolling interest shares as a component of Accrued expenses on our Consolidated Balance Sheets as of December 31, 2020 and 2019. It is possible that the value ultimately agreed upon with the noncontrolling interest shareholder could differ from our current estimate of the fair value. Subsequent to these noncontrolling interest shares becoming mandatorily redeemable, any increase or decrease in the fair value of such noncontrolling interest is included as a component of Other expense (income), net on our Consolidated Statements of Operations.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
R. REVENUES
Our revenues consist of storage rental revenues as well as service revenues and are reflected net of sales and value-added taxes. Storage rental revenues, which are considered a key driver of financial performance for the storage and information management services industry, consist primarily of recurring periodic rental charges related to the storage of materials or data (generally on a per unit basis) that are typically retained by customers for many years and revenues associated with our data center operations. Service revenues include charges for related service activities, the most significant of which include: (1) the handling of records, including the addition of new records, temporary removal of records from storage, refiling of removed records, customer termination and permanent removal fees, project revenues and courier operations, consisting primarily of the pickup and delivery of records upon customer request; (2) destruction services, consisting primarily of secure shredding of sensitive documents and the subsequent sale of shredded paper for recycling, the price of which can fluctuate from period to period; and (3) digital solutions including scanning, imaging and document conversion services of active and inactive records, and consulting services.
We account for revenue in accordance with ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”). Customers are generally billed monthly based on contractually agreed-upon terms, and storage rental and service revenues are recognized in the month the respective storage rental or service is provided, in line with the transfer of control to the customer. When storage rental fees or services are billed in advance, amounts related to future storage rental or prepaid service contracts are accounted for as deferred revenue and recognized upon the transfer of control to the customer, generally ratably over the contract term. Customer contracts generally include promises to provide monthly recurring storage and related services that are essentially the same over time and have the same pattern of transfer of control to the customer; therefore, most performance obligations represent a promise to deliver a series of distinct services over time (as determined for purposes of ASU 2014-09, a “series”). For those contracts that qualify as a series, we have a right to consideration from the customer in an amount that corresponds directly with the value of the underlying performance obligation transferred to the customer to date. This concept is known as "right to invoice” and we apply the “right to invoice” practical expedient to all revenues, with the exception of storage revenues in our Global Data Center Business (which are subject to leasing guidance). Additionally, each purchasing decision is fully in the control of the customer and; therefore, consideration beyond the current reporting period is variable and allocated to the specific period to which the consideration relates, which is consistent with the practical expedient.
Our Global Data Center Business features storage rental provided to the customer at contractually specified rates over a fixed contractual period. Storage rental revenue related to the storage component of our Global Data Center Business is recognized on a straight-line basis over the contract term in accordance with ASU 2016-02. The revenue related to the service component of our Global Data Center Business is recognized in the period the related services are provided.
The costs associated with the initial movement of customer records into physical storage and certain commissions are considered costs to obtain or fulfill customer contracts (“Contract Fulfillment Costs”). The following describes each of these Contract Fulfillment Costs recognized under ASU 2014-09:
INTAKE COSTS (AND ASSOCIATED DEFERRED REVENUE)
The costs of the initial intake of customer records into physical storage (“Intake Costs”) are deferred and amortized as a component of depreciation and amortization in our Consolidated Statements of Operations over three years, consistent with the transfer of the performance obligation to the customer to which the asset relates. In instances where such Intake Costs are billed to the customer, the associated revenue is deferred and recognized over the same three-year period.
COMMISSIONS
Certain commission payments that are directly associated with the fulfillment of long-term storage contracts are capitalized and amortized as a component of depreciation and amortization in our Consolidated Statements of Operations over three years, consistent with the transfer of the performance obligation to the customer to which the asset relates. Certain direct commission payments associated with contracts with a duration of one year or less are expensed as incurred under the practical expedient which allows an entity to expense as incurred an incremental cost of obtaining a contract if the amortization period of the asset that the entity otherwise would have recognized is one year or less.

DATA CENTER LESSOR CONSIDERATIONS
Our Global Data Center Business features storage rental provided to customers at contractually specified rates over a fixed contractual period. Prior to January 1, 2019, our data center revenue contracts were accounted for in accordance with ASC 840. Beginning on January 1, 2019, our data center revenue contracts are accounted for in accordance with ASU 2016-02. ASU 2016-02 provides a practical expedient which allows lessors to account for nonlease components (such as power and connectivity, in the case of our Global Data Center Business) with the related lease component if both the timing and pattern of transfer are the same for nonlease components and the lease component, and the lease component, if accounted for separately, would be classified as an operating lease. The single combined component is accounted for under ASU 2016-02 if the lease component is the predominant component and is accounted for under ASU 2014-09 if the nonlease components are the predominant components. We have elected to take this practical expedient.

S. STOCK-BASED COMPENSATION
We record stock-based compensation expense, utilizing the straight-line method, for the cost of stock options, restricted stock units (“RSUs”), performance units (“PUs”) and shares of stock issued under our employee stock purchase plan (“ESPP”) (together, "Employee Stock-Based Awards”).
For our Employee Stock-Based Awards made on or after February 20, 2019, we have included the following retirement provision:
Upon an employee’s retirement on or after attaining age 58, if the sum of (i) the award recipient’s age at retirement and (ii) the award recipient’s years of service with the company totals at least 70, the award recipient is entitled to continued vesting of any outstanding Employee Stock-Based Awards which include the 2019 Retirement Criteria subsequent to their retirement, provided that, for awards granted in the year of retirement, their retirement occurs on or after July 1 (the “2019 Retirement Criteria”).
Accordingly, (i) grants of Employee Stock-Based Awards to an employee who has met the 2019 Retirement Criteria on or before the date of grant, or will meet the Retirement Criteria before July 1 of the year of the grant, will be expensed between the date of grant and July 1 of the grant year and (ii) grants of Employee Stock-Based Awards to employees who will meet the 2019 Retirement Criteria during the award’s normal vesting period will be expensed between the date of grant and the date upon which the award recipient meets the 2019 Retirement Criteria.
Stock options and RSUs granted to recipients who meet the 2019 Retirement Criteria will continue vesting on the original vesting schedule. If an employee retires and has met the 2019 Retirement Criteria, stock options will remain exercisable for up to three years or the original expiration date of the stock options, if earlier. PUs granted to recipients who meet the 2019 Retirement Criteria will continue to vest and be delivered in accordance with the original vesting schedule of the applicable PU award and remain subject to the same performance conditions.

The substantial majority of stock-based compensation expense for Employee Stock-Based Awards is included in Selling, general and administrative expenses in the accompanying Consolidated Statements of Operations.
STOCK OPTIONS
Options are generally granted with exercise prices equal to the market price of the stock on the date of grant; however, in certain instances, options are granted at prices greater than the market price of the stock on the date of grant. The substantial majority of options we issue become exercisable ratably over a period three years from the date of grant and have a contractual life of 10 years from the date of grant, unless the holder’s employment is terminated sooner. Our non-employee directors are considered employees for purposes of our stock option plans and stock option reporting.
The substantial majority of the stock options outstanding at December 31, 2020 are based on the three-year vesting period (10 year contractual life) described above.
Our equity compensation plans generally provide that, upon a vesting change in control (as defined in each plan), any unvested options and other awards granted thereunder shall vest immediately if an employee is terminated as a result of the change in control or terminates their own employment for good reason (as defined in each plan). On January 20, 2015, our stockholders approved the adoption of the Iron Mountain Incorporated 2014 Stock and Cash Incentive Plan, as amended (the "2014 Plan”). 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, 2020 was 2,818,706.
The weighted average fair value of stock options granted in 2020, 2019 and 2018 was $2.35, $3.58 and $3.50 per share, respectively. These values were estimated on the date of grant using the Black-Scholes option pricing model. The weighted average assumptions used for grants in the years ended December 31, 2020, 2019 and 2018 are as follows:

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

PERFORMANCE UNITS
The PUs we issue vest based on our performance against predefined operational and share based targets.

For awards granted in 2019 and thereafter, the vesting is subject to a minimum level of return on invested capital (“ROIC”) in the third year of the performance period, and thereafter the number of PUs earned is based on (i) the revenue performance for each year averaged at the end of the three-year performance period, (ii) the revenue exit rate of new products in the last quarter of the three-year performance period and (iii) a TSR Target. With respect to the PUs granted in 2019 and thereafter, the number of PUs earned may range from 0% to 219% of the initial award.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
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. As detailed above, PUs granted:
On or after February 20, 2019, are subject to the 2019 Retirement Criteria. PUs granted to recipients who meet the 2019 Retirement Criteria will continue to vest and be delivered in accordance with the original vesting schedule of the applicable PU award and remain subject to the same performance conditions.
Prior to February 20, 2019, 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, 2020, 2019 and 2018, we issued 425,777, 380,856 and 353,507 PUs, respectively. We forecast the likelihood of achieving the predefined targets for our PUs in order to calculate the expected PUs to be earned. We record a compensation charge based on either the forecasted PUs to be earned (during the performance period) or the actual PUs earned (at the three-year anniversary of the grant date) over the vesting period for each of the awards. The fair value of PUs based on our performance against predefined targets is the excess of the market price of our common stock at the date of grant over the purchase price (which is typically zero). For PUs earned based on a market condition, we utilize a Monte Carlo simulation to fair value these awards at the date of grant, and such fair value is expensed over the three-year performance period. As of December 31, 2020, we expected 100%, 100% and 0% achievement of the predefined targets associated with the awards of PUs made in 2020, 2019 and 2018, respectively.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
EMPLOYEE STOCK PURCHASE PLAN
We offer an ESPP in which participation is available to substantially all United States and Canadian employees who meet certain service eligibility requirements. The ESPP provides for the purchase of our common stock by eligible employees through successive offering periods. We have historically had 2 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, 2020, 2019 and 2018, there were 159,853, 129,505 and 119,123 shares, respectively, purchased under the ESPP. As of December 31, 2020, we have 216,287 shares available under the ESPP.

As of December 31, 2020, unrecognized compensation cost related to the unvested portion of our Employee Stock-Based Awards was $39,056 and is expected to be recognized over a weighted-average period of 1.7 years.
We issue shares of our common stock for the exercises of stock options, and the vesting of RSUs, PUs and shares of our common stock under our ESPP from unissued reserved shares.
T. OTHER EXPENSE (INCOME), NET
Consolidated other expense (income), net for the years ended December 31, 2020, 2019 and 2018 consists of the following:

(1)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, includes gains or losses primarily related to (i) borrowings in certain foreign currencies under our Revolving Credit Facility (as defined in Note 6), (ii) our previously outstanding Euro Notes (as defined in Note 6), (iii) certain foreign currency denominated intercompany obligations of our foreign subsidiaries to us and between our foreign subsidiaries, which are not considered permanently invested and (iv) amounts that are paid or received on the net settlement amount from forward contracts (as more fully discussed in Note 5).
(2)Other, net for the year ended December 31, 2020 consists primarily of changes in the estimated value of our mandatorily redeemable noncontrolling interests as well as losses on our equity method investments.
U. INCOME TAXES
Accounting for income taxes requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the tax and financial reporting bases of assets and liabilities and for loss and credit carryforwards. Valuation allowances are provided when recovery of deferred tax assets does not meet the more likely than not standard as defined in GAAP. We have elected to recognize interest and penalties associated with uncertain tax positions as a component of the Provision (benefit) for income taxes in the accompanying Consolidated Statements of Operations.

V. 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, 2020, 2019 and 2018 is as follows:

W. NEW ACCOUNTING PRONOUNCEMENTS
RECENTLY ADOPTED ACCOUNTING PRONOUNCEMENTS
In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement (“ASU 2018-13”), which makes a number of changes meant to add, modify or remove certain disclosure requirements associated with the movement of our financial assets and liabilities among the three levels of the fair value hierarchy. We adopted ASU 2018-13 on January 1, 2020. ASU 2018-13 did not have a material impact on our consolidated financial statements.

OTHER AS YET ADOPTED ACCOUNTING PRONOUNCEMENTS
In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848) (“ASU 2020-04”). ASU 2020-04 provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships, and other transactions, for a limited period of time, to ease the potential burden of recognizing the effects of reference rate reform on financial reporting. The amendments in ASU 2020-04 apply to contracts, hedging relationships and other transactions that reference the London Inter-Bank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued due to the global transition away from LIBOR and certain other interbank offered rates. An entity may elect to apply the amendments provided by ASU 2020-04 beginning March 12, 2020 through December 31, 2022. We are currently evaluating these amendments as they relate to our contracts, hedging relationships and other transactions that reference LIBOR, as well as the impact of ASU 2020-04 on our consolidated financial statements.
In December 2019, the FASB issuedASU No. 2019-12, Income Taxes (Topic 740) (“ASU 2019-12”). ASU 2019-12 simplifies the accounting for income taxes by removing certain exceptions for recognizing deferred taxes for investments, performing intra-period allocation and calculating income taxes in interim periods. ASU 2019-12 also adds guidance to reduce complexity in certain areas, including recognizing deferred taxes for tax goodwill and allocating taxes to members of a consolidated group. ASU 2019-12 is effective for us on January 1, 2021. We do not expect that ASU 2019-12 will have a material impact on our consolidated financial statements.
3. Derivative InstrumentsACQUISITIONS AND JOINT VENTURES
ACQUISITIONS
We account for acquisitions using the acquisition method of accounting, and, Hedging Activitiesaccordingly, the assets and liabilities acquired are recorded at their estimated fair values and the results of operations for each acquisition have been included in our consolidated results from their respective acquisition dates.
A. ACQUISITIONS COMPLETED DURING THE YEAR ENDED DECEMBER 31, 2020
Prior to January 9, 2020, we owned a 25% equity interest in OSG Records Management (Europe) Limited ("OSG"). On January 9, 2020, we acquired the remaining 75% equity interest in OSG for cash consideration of approximately $95,500 (the "OSG Acquisition"). The OSG Acquisition enabled us to extend our Global RIM Business in Russia, Ukraine, Kazakhstan, Belarus, and Armenia. The results of OSG are fully consolidated within our consolidated financial statements from the closing date of the OSG Acquisition. In connection with the OSG Acquisition, our previously held 25% equity investment in OSG was remeasured to fair value at the closing date of the OSG Acquisition; as a result, we recorded a gain of approximately $10,000 during the first quarter of 2020, which is included as a component of Other expense (income), net on our Consolidated Statements of Operations. The fair value of the 25% equity investment in OSG was determined based on the purchase price of the OSG Acquisition.
On February 17, 2020, in order to enhance our existing operations in the United Arab Emirates, we acquired Glenbeigh Records Management DWC-LLC, a storage and records management company, for total cash consideration of approximately $29,100.

At the closing of the IODC Transaction, we paid approximately $1,347,000. In February 2019, we paid approximately $31,000 in additional purchase price associated with the execution of customer contracts from the closing through the one-year anniversary of the IODC Transaction, which, net of amortization, is reported as a third-party commissions asset as a component of Other within Other assets, net in our Consolidated Balance Sheets at December 31, 2020 and 2019.
OTHER 2018 NOTEWORTHY ACQUISITIONS
On May 25, 2018, in order to further expand our data center operations in Europe, we acquired EvoSwitch Netherlands B.V. and EvoSwitch Global Services B.V., a data center colocation space and solutions provider with a data center in Amsterdam (the “EvoSwitch Transaction”), for (i) cash consideration of 189,000 Euros (or approximately $222,000, based upon the exchange rate between the Euro and the United States dollar on the closing date of the EvoSwitch Transaction) and (ii) $25,000 of additional consideration in the form of future services we will provide to the seller, which is included in purchase price holdbacks and other in the allocation of the purchase price paid table below.

3. ACQUISITIONS AND JOINT VENTURES (CONTINUED)
Allocations of the purchase price for acquisitions are based on estimates of the fair value of the net assets acquired and are subject to adjustment upon the finalization of the purchase price allocations. The accounting for business combinations requires estimates and judgments regarding expectations for future cash flows of the acquired business, and the allocations of those cash flows to identifiable tangible and intangible assets, in determining the assets acquired and liabilities assumed. The fair values assigned to tangible and intangible assets acquired and liabilities assumed, including contingent consideration, are based on management’s best estimates and assumptions, as well as other information compiled by management, including valuations that utilize customary valuation procedures and techniques. The estimates and assumptions underlying the initial valuations are subject to the collection of information necessary to complete the valuations within the measurement periods, which are up to one year from the respective acquisition dates.
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 2020 and year ended December 31, 2020 were not material to our results from operations.
JOINT VENTURES
A. FRANKFURT DATA CENTER JOINT VENTURE
In October 2020, we formed a joint venture (the “Frankfurt JV”) with AGC Equity Partners (“AGC”) to design and develop a 280,000 square foot, 27 megawatt, hyperscale data center currently under development in Frankfurt, Germany (the “Frankfurt JV Transaction”). AGC acquired an 80% equity interest in the Frankfurt JV, while we retained a 20% equity interest (the "Frankfurt JV Investment"). The total cash consideration for the 80% equity interest sold to AGC was approximately $105,000. We received approximately $93,300 (gross of certain transaction expenses) upon the closing of the Frankfurt JV, and we are entitled to receive an additional approximately $11,700 upon the completion of development of the data center, which we expect to occur in the second quarter of 2021. In connection with the Frankfurt JV Transaction, we also entered into agreements whereby we will earn various fees, including property management and construction and development fees, for services we are providing to the Frankfurt JV.
As a result of the Frankfurt JV Transaction, we recognized a gain of approximately $24,100, representing the excess of the fair value of the consideration received over the carrying value of the assets, which consisted primarily of land and land development assets which were previously included within our Global Data Center Business segment.
We account for our Frankfurt JV Investment as an equity method investment. At the closing date of the Frankfurt JV Transaction, the fair value of the Frankfurt JV Investment was approximately $23,300. The carrying value of our Frankfurt JV Investment at December 31, 2020 was $26,500, which is presented as a component of Other within Other assets, net in our Consolidated Balance Sheet.
B. MAKESPACE JOINT VENTURE
In March 2019, we formed a joint venture entity (the “MakeSpace JV”) with MakeSpace Labs, Inc., a consumer storage provider (“MakeSpace”). In the second quarter of 2020, we committed to participate in a round of equity funding for the MakeSpace JV whereby we agreed to contribute $36,000 of the $45,000 being raised in installments beginning in May 2020 through October 2021. We account for our investment in the MakeSpace JV as an equity method investment. At December 31, 2020 and 2019, we owned approximately 39% and 34%, respectively, of the outstanding equity in the MakeSpace JV, and the carrying value of our investment in the MakeSpace JV at December 31, 2020 and 2019 was $16,924 and $18,570, respectively, which is presented as a component of Other within Other assets, net in our Consolidated Balance Sheets. See Note 4 for additional detail on the divestment of our consumer storage business that was completed in conjunction with the formation of the MakeSpace JV.

4. DIVESTMENTS
In March 2019, we contributed our customer contracts and certain intellectual property and other assets used by us to operate our consumer storage business in the United States and Canada (the “IM Consumer Storage Assets”) and approximately $20,000 in cash (gross of certain transaction expenses) (the “Cash Contribution”) to the MakeSpace JV (the "Consumer Storage Transaction"), established by us and MakeSpace. Upon the closing of the Consumer Storage Transaction on March 19, 2019, the MakeSpace JV owned (i) the IM Consumer Storage Assets, (ii) the Cash Contribution and (iii) the customer contracts, intellectual property and certain other assets used by MakeSpace to operate its consumer storage business in the United States. As part of the Consumer Storage Transaction, we received an initial equity interest of approximately 34% in the MakeSpace JV (the "MakeSpace Investment"). In connection with the Consumer Storage Transaction and the investment in the MakeSpace JV, we also entered into a storage and service agreement with the MakeSpace JV to provide certain storage and related services to the MakeSpace JV (see Note 11).
We have concluded that the divestment of the IM Consumer Storage Assets in the Consumer Storage Transaction does not meet the criteria to be reported as discontinued operations in our consolidated financial statements, as our decision to divest this business does not represent a strategic shift that will have a major effect on our operations and financial results. Accordingly, the revenues and expenses associated with this business are presented as a component of Income (loss) from continuing operations in our Consolidated Statements of Operations for the year ended December 31, 2019 through the closing date of the Consumer Storage Transaction and for the year ended December 31, 2018 and the cash flows associated with this business are presented as a component of cash flows from continuing operations in our Consolidated Statements of Cash Flows for the year ended December 31, 2019 through the closing date of the Consumer Storage Transaction and for the year ended December 31, 2018.
As a result of the Consumer Storage Transaction, we recorded a gain on sale of approximately $4,200 to Other expense (income), net, in the first quarter of 2019, representing the excess of the fair value of the consideration received over the sum of (i) the carrying value of our consumer storage operations and (ii) the Cash Contribution.
5. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES
Derivative instruments we are party to include: (i) interest rate swap agreements (which are designated as cash flow hedges), (ii) cross-currency swap agreements (which are designated as net investment hedges) and (iii) foreign exchange currency forward contracts (which are not designated as hedges).
INTEREST RATE SWAP AGREEMENTS DESIGNATED AS CASH FLOW HEDGES
In March 2018, we entered into interest rate swap agreements to limit our exposure to changes in interest rates on a portion of our floating rate indebtedness. As of December 31, 2020 and 2019, we had $350,000 in notional value of interest rate swap agreements outstanding, which expire in March 2022. Under the interest rate swap agreements, we receive variable rate interest payments associated with the notional amount of each interest rate swap, based upon one-month LIBOR, in exchange for the payment of fixed interest rates as specified in the interest rate swap agreements.
In July 2019, we entered into forward-starting interest rate swap agreements to limit our exposure to changes in interest rates on a portion of our floating rate indebtedness once our current interest rate swap agreements expire in March 2022. The forward-starting interest rate swap agreements have $350,000 in notional value, commence in March 2022 and expire in March 2024. Under the swap agreements, we will receive variable rate interest payments based upon one-month LIBOR, in exchange for the payment of fixed interest rates as specified in the interest rate swap agreements.
We have designated these interest rate swap agreements, including the forward-starting interest rate swap agreements, as cash flow hedges. Unrealized gains are recognized as assets, while unrealized losses are recognized as liabilities.

5. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES (CONTINUED)
CROSS-CURRENCY SWAP AGREEMENTS DESIGNATED AS A HEDGE OF NET INVESTMENT
In August 2019, we entered into cross-currency swap agreements to hedge the variability of exchange rate impacts between the United States dollar and the Euro. Under the terms of the cross-currency swap agreements we notionally exchanged approximately $110,000 at an interest rate of 6.0% for approximately 99,055 Euros at a weighted average interest rate of approximately 3.65%. These cross-currency swap agreements expire in August 2023 (“August 2023 Cross Currency Swap Agreements”).
In September 2020, we entered into cross-currency swap agreements to hedge the variability of exchange rates impacts between the United States dollar and the Euro. Under the terms of the cross-currency swap agreements, we notionally exchanged approximately $359,200 at an interest rate of 4.5% for approximately 300,000 Euros at a weighted average interest rate of approximately 3.4%. These cross-currency swap agreements expire in February 2026 (“February 2026 Cross Currency Swap Agreements”).
We have designated these cross-currency swap agreements as hedge of net investments against certain of our Euro denominated subsidiaries and they require an exchange of the notional amounts at maturity. These cross-currency swap agreements are marked to market at each reporting period, representing the fair values of the cross-currency swap agreements, and any changes in fair value are recognized as a component of Accumulated other comprehensive items, net. Unrealized gains are recognized as assets while unrealized losses are recognized as liabilities.
FOREIGN EXCHANGE CURRENCY FORWARD CONTRACTS NOT DESIGNATED AS HEDGING INSTRUMENTS
On occasion, we enter into forward contracts to hedge our exposures associated with certain foreign currencies. 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 thethese 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, 2016,2020 and 2019, we had no0 outstanding forward contracts outstanding. contracts.

a. Credit Agreement6. DEBT (CONTINUED)
On August 21, 2017, we entered into a newA. CREDIT AGREEMENT
Our 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“Revolving Credit Facility"Facility”) and a term loan (the "Term Loan"“Term Loan A”). 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. Under the Credit Agreement, we have the option to request additional commitments of up to $1,260,000, in the form of term loans or through increased commitments under the Revolving Credit Facility, subject to the conditions specified in the Credit Agreement. The Credit Agreement is scheduled to mature on June 4, 2023, at which point all obligations become due. The original principal amount of the Term Loan A was $250,000 and is to be paid in quarterly installments in an amount equal to $3,125 per quarter, with the remaining balance due on August 21, 2022.June 4, 2023.
On December 20, 2019, we entered into an amendment to the Credit Agreement. This amendment amended the definition of EBITDA and certain other definitions and restrictive covenants contained in the Credit Agreement.
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, 2017,2020, we had $466,593 and $243,750 of0 outstanding borrowings under the Revolving Credit Facility and $215,625 aggregate outstanding principal amount under 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,A. At December 31, 2020, we also had various outstanding letters of credit totaling $52,847$3,232 under the Revolving Credit Facility. The remaining amount available for borrowing under the Revolving Credit Facility as of December 31, 2017,2020, which is based on IMI'sIMI’s leverage ratio, the last 12 months' earnings before interest, taxes, depreciation and amortization and rent expense ("EBITDAR"(“EBITDAR”), other adjustments as defined in the Credit Agreement and current external debt, was $1,230,560$1,746,768 (which amount represents the maximum availability as of such date). Available borrowings under the Revolving Credit Facility are subject to compliance with our indenture covenants as discussed below. The average interest rate in effect for all outstanding borrowings under the Credit Agreement was 3.4%1.9% and 3.3% as of December 31, 2017.2020 and 2019, respectively. The average interest rate in effect under the Revolving Credit Facility was 3.5% and ranged from 3.4% to 5.5%3.2% as of December 31, 20172019, and the interest rate in effect under the Term Loan A as of December 31, 20172020 and 2019 was 1.9% and 3.5%., respectively.
IMI’s wholly owned subsidiary, Iron Mountain Information Management, LLC (“IMIM”), has an incremental term loan B with a principal amount of $700,000 (the “Term Loan B”). The Credit Agreement, our indenturesTerm Loan B, which matures on January 2, 2026, was issued at 99.75% of par. The Term Loan B holders benefit from the same security and guarantees as other 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 defaultborrowings under the Credit Agreement, our indentures orAgreement. The Term Loan B holders also benefit from the same affirmative and negative covenants as other agreements governing our indebtedness.borrowings under the Credit Agreement; however, the Term Loan B holders are not generally entitled to the benefits of the financial covenants under the Credit Agreement.
Principal payments on the Term Loan B are to be paid in quarterly installments of $1,750 per quarter during the period June 30, 2018 through December 31, 2025, with the balance due on January 2, 2026. The Credit Agreement uses EBITDAR-based calculationsTerm Loan B may be prepaid without penalty at any time. The Term Loan B bears interest at a rate of LIBOR plus 1.75%. As of December 31, 2020, we had $679,621 aggregate outstanding principal amount under the Term Loan B. The interest rate in effect under Term Loan B as the primary measures of financial performance, including leverageDecember 31, 2020 and fixed charge coverage ratios.2019 was 1.9% and 3.6%, respectively.

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:B. NOTES ISSUED UNDER INDENTURES

 Maximum allowable of 6.5-7.0(3)(4)
Fixed charge coverage ratio2.4

 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 4⅜% Notes and the 5⅜% 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(i) is effectively subordinated to all of our secured indebtedness, including under the Credit Agreement, to the extent of the value of the collateral securing such indebtedness, (ii) ranks pari passu in right of payment with each other and with debt outstanding under the Credit Agreement, except the 53/4% Notes which aresenior notes shown below and other “senior debt” we incur from time to time, and (iii) is structurally subordinated to all liabilities of our subsidiaries that do not guarantee such series of notes.

E. ACCOUNTS RECEIVABLE SECURITIZATION PROGRAM
We participate in an accounts receivable securitization program (the "Accounts“Accounts Receivable Securitization Program"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“Accounts Receivable Securitization Special Purpose Subsidiaries"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")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.

On March 31, 2020, we amended the Accounts Receivable Securitization Program to (i) increase the maximum amount available from $275,000 to $300,000 and (ii) extend the maturity date from July 30, 2020 to July 30, 2021, at which point all obligations become due. The full amount outstanding under the Accounts Receivable Securitization Program is classified within the current portion of long-term debt in our Consolidated Balance Sheet as of December 31, 2020 and 2019. As of December 31, 2020, the maximum availability allowed and amount outstanding under the Accounts Receivable Securitization Program was $274,100 and $85,000, respectively. At December 31, 2019, both the maximum availability and amount outstanding under the Accounts Receivable Securitization Program was $272,062. The interest rate in effect under the Accounts Receivable Securitization Program was 1.1% and 2.8% as of December 31, 2020 and 2019, respectively.

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 PoolingF. 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 two2 separate cash poolsCash Pools with BMG, one1 of which we utilize to manage global liquidity requirements for our QRSsqualified REIT subsidiaries (the "QRS“QRS Cash Pool"Pool”) and the other for our TRSstaxable REIT subsidiaries (the "TRS“TRS Cash Pool"Pool”). During the second quarter of 2017, weWe have 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
The approximate amount of December 31, 2017, we had athe net cash position, of approximately $5,700 ingross position and outstanding debit balances for 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 consistedas of a gross cash position of approximately $229,600 less outstanding debit balances of approximately $229,600 by participating subsidiaries).

G. LETTERS OF CREDIT

As of December 31, 2020, we had outstanding letters of credit totaling $36,160, of which $3,232 reduce our borrowing capacity under the Revolving Credit Facility (as described above). The letters of credit expire at various dates between January 2021 and January 2033.
H. DEBT COVENANTS
The Credit Agreement, our bond indentures and other agreements governing our indebtedness contain certain restrictive financial and operating covenants, including covenants that restrict our ability to complete acquisitions, pay cash dividends, incur indebtedness, make investments, sell assets and take 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 bond indentures or other agreements governing our indebtedness. The Credit Agreement requires that we satisfy a fixed charge coverage ratio, a net total lease adjusted leverage ratio and a net secured debt lease adjusted leverage ratio on a quarterly basis and our bond indentures require that, among other things, we satisfy a leverage ratio (not lease adjusted) or a fixed charge coverage ratio (not lease adjusted), as a condition to taking actions such as paying dividends and incurring indebtedness.
The Credit Agreement uses EBITDAR-based calculations and the bond indentures use EBITDA-based calculations as the primary measures of financial performance for purposes of calculating leverage and fixed charge coverage ratios. The bond indenture EBITDA-based calculations include our consolidated subsidiaries, other than those we have designated as “Unrestricted Subsidiaries” as defined in the bond indentures. Generally, the Credit Agreement and the bond indentures use a trailing four fiscal quarter basis for purposes of the relevant calculations and require certain adjustments and exclusions for purposes of those calculations, which make the calculation of financial performance for purposes of those calculations under the Credit Agreement and bond indentures not directly comparable to Adjusted EBITDA as presented herein. We are in compliance with our leverage and fixed charge coverage ratios under the Credit Agreement, our bond indentures and other agreements governing our indebtedness as of December 31, 2020 and 2019. Noncompliance with these leverage and fixed charge coverage ratios would have a material adverse effect on our financial condition.

B. SELF-INSURED LIABILITIES
We are self-insured up to certain limits for costs associated with workers’ compensation claims, vehicle accidents, property and general business liabilities, and benefits paid under employee healthcare and short-term disability programs. At December 31, 2020 and 2019, there were $47,959 and $43,127, respectively, of self-insurance accruals reflected in Accrued expenses on our Consolidated Balance Sheets. The measurement of these costs requires the consideration of historical cost experience and judgments about the present and expected levels of cost per claim. We account for these costs primarily through actuarial methods, which develop estimates of the undiscounted liability for claims incurred, including those claims incurred but not reported. These methods provide estimates of future claim costs based on claims incurred as of the balance sheet date.

The following data summarizesother natural disasters. A portion of the consolidatingdefense 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. While the outcome of litigation is inherently uncertain, we do not believe any current litigation will have a material adverse effect on our consolidated financial condition, results of IMIoperations or cash flows.

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.

profits to be distributed prior to any REIT distributions, which may affect the character of each distribution to our stockholders, including whether and to what extent each distribution is characterized as a qualified or nonqualified ordinary dividend. In addition, certain of our distributions qualify as capital gain distributions.

In January 2018, the Underwriters, pursuant to the Underwriting Agreement, exercised an option to purchase an additional 2,175,000 shares of common stock, which after deducting underwriters’ commissions and the per share value of the dividend we declared on our common stock on October 24, 2017, resulted in net proceeds of approximately $76,200.

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”).

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.

 $0.53
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.

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.

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 TaxesTAXES
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,taxable REIT subsidiaries (“TRSs”), which hold our domestic operations that may not be REIT-compliant as currently operated and structured, is subject, as applicable, to federal and state corporate income tax. In addition, we and our subsidiaries continue to be subject to foreign income taxes in other jurisdictions in which we have business operations or a taxable presence, regardless of whether assets are held or operations are conducted through subsidiaries disregarded for federal income tax purposes or TRSs. We will also be subject to a separate corporate income tax on any gains recognized on the sale or disposition of any asset previously owned by a C corporation during a five-year period followingafter the date on which that asset waswe first owned bythe asset as a REIT asset that are attributable to "built-in" gains“built-in gains” with respect to that asset on that date (e.g. with respectdate. We will also be subject to the REIT conversion, the assets that we owned on January 1, 2014). Thisa 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.our acquisition activities. If we fail to remain qualified for taxation as a REIT, we will be subject to federal income tax at regular corporate income tax rates. Even if we remain qualified for taxation as a REIT, we may be subject to some federal, state, local and foreign taxes on our income and property in addition to taxes owed with respect to our TRS operations. In particular, while state income tax regimes often parallel the federal income tax regime for REITs, many states do not completely follow federal rules and some do not follow them at all.
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.

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.

Our effective tax rates for the years ended December 31, 2015, 20162020, 2019 and 20172018 were 23.3%7.9%, 30.6%18.3% and 12.0%10.4%, 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 (“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 tax rate of 35.0%21.0% 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.were:

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.

9. INCOME TAXES (CONTINUED)
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 As of December 31, 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”)TRSs outside the United States and, therefore, during 2016, we recognized a decrease in our provision for income taxes from continuing operations inStates. With the amountexception 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,certain limited instances, we no longer provide incremental foreign withholding taxes on the retained book earnings of these unconverted foreign TRSs, which was approximately $230,000$262,379 as of December 31, 2017.2020. 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 subsidiariesQRSs 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 provision (benefit) provision for income taxes in the accompanying Consolidated Statements of Operations. We recorded a decrease of $1,499 for gross interest and penalties for the year ended December 31, 2020. We recorded an increase of $2,173, $1,805$1,780 and $289$1,961 for gross interest and penalties for the years ended December 31, 2015, 20162019 and 2017,2018, respectively. We had $8,646$6,212 and $7,061$9,282 accrued for the payment of interest and penalties as of December 31, 20162020 and 2017,2019, respectively.

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, 20152019, 2018 and 20162017 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 20012002 through 2003 and 20082010 through 20142015 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, 2016,2020, we had $59,466$25,969 of reserves related to uncertain tax positions, of which $56,303$23,402 and $3,163$2,567 is included in other long-term liabilities and deferred income taxes, respectively, in the accompanying Consolidated Balance Sheet. As of December 31, 2017,2019, we had $38,533$35,068 of reserves related to uncertain tax positions, of which $34,003$31,992 and $4,530$3,076 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.

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.

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.

10. SEGMENT INFORMATION (CONTINUED)
The accounting policies of the reportable segments are the same as those described in Note 2. During the fourth quarter of 2020, we changed our definition of Adjusted EBITDA to (a) exclude stock-based compensation expense and (b) include our share of Adjusted EBITDA from our unconsolidated joint ventures. All prior periods have been recast to conform to these changes. We now define Adjusted EBITDA for each segment is defined as income (loss) from continuing operations before interest expense, net, provision (benefit) for income taxes, depreciation and amortization (inclusive of our share of Adjusted EBITDA from our unconsolidated joint ventures), and also excludesexcluding certain items that we do not believe are notto be 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).
EXCLUDED
Significant Acquisition Costs
Restructuring Charges
Intangible impairments
(Gain) loss on disposal/write-down of property, plant and equipment, net (including real estate)
Other expense (income), net
Stock-based compensation expense
COVID-19 Costs (as defined below)

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

A reconciliation of Income (Loss) from Continuing Operations to Adjusted EBITDA to income (loss) from continuing operations on a consolidated basis for the years ended December 31, 2020, 2019 and 2018 is as follows:

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.

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

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.

In October 2019, we announced Project Summit, our global program designed to 2017 (0.0%) is primarilybetter position us for future growth and achievement of our strategic objectives. We expanded Project Summit during the first quarter of 2020 to include additional opportunities to streamline our business and operations, as well as accelerated the timing of certain opportunities previously identified. Such opportunities include leveraging new technology solutions to enable us to modernize our service delivery model and more efficiently utilize our fleet, labor and real estate. As a result of the impactprogram, we expect to reduce the number of positions at vice president and above by approximately 45%. The total program is expected to reduce our total managerial and administrative workforce by approximately 700 positions by the Deemed Repatriation Transition Tax associated with the Tax Reform Legislation that impacted the characterizationend of 2021. We have also reduced 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 Agentservices 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.operations workforce.

The activities associated with Project Summit began in the At The Market (ATM) Equity Program wasfourth quarter of 2019 and are expected to be substantially complete by the end of 2021.
We estimate that the implementation of Project Summit will result in total operating expenditures ("Restructuring Charges") of approximately $440,000.
Equity Offering
On December 12, 2017, we entered into an underwriting agreement (the "Underwriting Agreement")$450,000 that primarily consist of: (1) employee severance costs; (2) internal costs associated with a syndicatethe development and implementation of 16 banks (the “Underwriters”)Project Summit initiatives; (3) professional fees, primarily related to third party consultants who are assisting with the public offering by usdesign and execution of 14,500,000 shares (the “Firm Shares”)various initiatives as well as project management activities and (4) system implementation and data conversion costs.
Restructuring Charges included in the accompanying Consolidated Statement of our common stock (the “Equity Offering”). The offering price to the publicOperations for the Equity Offering was $37.00 per share,years ended December 31, 2020 and we agreed to pay the Underwriters an underwriting commission of $1.38195 per share. The net proceeds to us2019, and 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 sharesinception 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.

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.

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.
