## 2015 Annual Financial Report and Stockholder Letter



Powered by TCPDF (www.tcpdf.org)



## Dear Fellow Stockholders,

During 2015, we continued to build upon the durability of our business and improved the trajectory of our performance, both on the top and bottom lines. We had an active year; we announced a planned acquisition that will strengthen our global platform and enhance our financial results. And, we introduced a transformation plan that aligns our talent to better capitalize on opportunities and drives increased cash flow, which supports sustainable dividend growth that can be counted on even in these volatile times.

Our strong financial and operating results met or exceeded our expectations in constant dollars this year. Like many multinational companies, the strength of the U.S. dollar continued to impact our reported revenue. However, when looking through to fundamental performance, we have achieved a significant turnaround in the business in the last two years. We've gone from negative internal revenue growth in both 2012 and 2013 to 1% positive internal growth in 2014, and in 2015, we achieved further improvement with 1.5% growth.

This is testament to the hard work our organization has undertaken to achieve net positive records volume growth in all major markets, enhance customer service and retention, attract new customers, stabilize service revenue declines, further penetrate emerging markets and advance adjacent business opportunities.

## Constant Dollar Growth Consistent with Long-term Objectives

On a constant dollar basis, we grew total revenue in 2015 by 2%, reflecting continued storage rental gains of 4%. This was driven primarily by storage rental internal growth of 3% from continued strong performance in our North American Data Management, Other International and Western European segments. As we look forward to 2016, these underlying trends remain consistent, and we expect internal storage rental revenue growth to remain in the mid-2% range.

Storage volume growth is an important indicator in our business. During the year, we added 43 million cubic feet of new records from new and existing customers, or net volume growth of 8 million cubic feet after destructions and customer terminations. Our unwavering focus on delighting our customers resulted in continued strong customer retention of 98% in records management, underscoring the durability of our storage rental revenue.

As we have noted in recent years, service revenue has declined as physical records and data backup tapes become more archival. We were able to offset this by growing service revenue in other lines of business such as scanning and shredding. As a result for the year, internal service revenue growth was flat. We made good progress on service gross margins, ending 2015 in line with our exit rate goal. There will be variability in our service business as the mix shifts to more project revenue and away from activity-based services such as transportation and handling; however, we expect to maintain similar average gross margins for 2016. Going forward, we will focus on growing overall service gross profits, as some new offerings have lower margins than core services. However, these services are less capital intensive, so they deliver similar, attractive returns.

## Excellent Progress on Pillars of Five-year Growth Plan

In October 2015, we updated and extended our strategic plan to 2020. Our five-year plan continues to revolve around the three pillars we've previously outlined: driving continued profitable growth in our developed markets, extending our reach into higher-growth emerging markets, and scaling adjacent business opportunities. In addition to our strong financial performance in 2015, we made good progress against our objectives in each of these three pillars as well as in the foundational elements – the Talent and Transformation initiative and Real Estate – that support our strategy and dividend growth. We are achieving this by better using our people, capital and real estate assets to support both near- and long-term growth in the business.

## Improved Performance in Developed Markets

During the last couple of years, our records management volume in developed markets had been relatively flat and slightly declining in North America; however, our recent focus on getting more growth from these markets has driven improved performance. In 2015, we achieved positive internal storage growth, stabilized records management service revenues and added roughly 3 million cubic feet of net new records prior to acquisitions.

Our goal is to increase revenue growth from around 1% today to roughly 3%, in developed markets whilst maintaining the exceptional profitability that is typical of these markets. We aim to do this through ongoing optimization and leveraging our deep customer loyalty to add new services and product lines. Our typical storage-based customer relationship lasts on average an extraordinary 50 years, and the average life of records stored with us is more than 15 years.

## Emerging Markets Offer High-growth Potential

In emerging markets, our business has grown from 10% of total revenue in 2013 to nearly 15% at the end of 2015 on a constant dollar basis. We are driving strong internal growth in these markets and have a sizable acquisition pipeline, supporting our confidence in reaching our goal of 16% of total revenue from these markets by the end of 2016, and 20% by 2020.

Despite the impact of the strong U.S. dollar on reported revenue, we manage foreign currency impact at the income level because our expenses are denominated in the same local currencies as our revenues, and we are increasingly moving more of our debt outside the United States. Additionally, using strong dollars to invest in high-growth emerging markets gives us a



lower cost basis and sets us up to realize significant value creation, as economic growth in these markets typically outpaces that of the United States over the longer term.

## Significant Progress in Adjacent Businesses

We also have a goal to generate 5% of our total revenue from adjacent businesses by the end of 2020, up from just 2% at the end of 2015. Today, our adjacent businesses consist of our data center operations and recently acquired art storage business. We closed on Crozier Fine Arts Storage in December and are pleased with the integration whilst retaining the key management talent that made it the leading art storage business in the United States. We believe the estimated billion-dollar global market is poised for a similar consolidation opportunity as we saw in records management years ago, and we have a plan to grow this business to $100 million within three years.

We had a fairly aggressive goal to finish 2015 with an adjacent business revenue run rate of $50 million from a starting point below $20 million. We achieved that goal, which supports our planned shift in mix to have 25% of our revenue coming from both higher growth emerging markets and adjacent businesses by 2020.

## Strategy Pillars Rest on Solid Foundation

In addition, we have made significant progress on the foundational elements of our strategy, including our Transformation and Talent initiative. We believe these two go hand in hand to ensure we have the right structure, hence transformation, and the right talent to execute our strategy. Transformation primarily refers to streamlining processes and systems to enable us to be faster to market and capable of scaling for new businesses and supporting growth in new markets. Our Transformation initiative resulted in $50 million of run-rate net savings at the end of 2015, which will be fully realized in 2016. We are currently implementing the next set of initiatives that will deliver an additional $50 million of savings by year end 2016. And the full amount of the $125 million program will be reflected in our 2018 results. Importantly, the cost to achieve these savings in each year is offset by the savings.

We also view real estate as a key part of our foundation, where we invested roughly $170 million during 2015. We remain keenly focused on how we allocate capital in this area and are focused on four major areas, all of which generate attractive returns. Our first priority is to invest in racking to accommodate net new volume growth we achieve annually. Our second priority is real estate consolidation, which may include both building and racking investment to improve operating efficiencies and enhance facility utilization. Third, we plan to continue to invest in our data center business in a deliberate manner driven by customer commitments. And fourth, we look to complete select opportunistic lease buy-ins where we can acquire buildings at attractive valuations relative to market pricing or where it is strategically important to own.

## Recall Acquisition Enhances Core Growth Strategy

In June 2015, we announced an agreement to acquire Recall Holdings Limited, another global player in the information management business, in a stock transaction. We believe this transaction will accelerate our already successful strategy and create a company with a broader footprint and enhanced growth profile. The combined company will be better positioned to capitalize on the significant global opportunities across developed and emerging markets.

As this is primarily a stock deal, both companies' shareholders stand to benefit from the meaningful cost synergies and accretion in earnings and cash flow that ultimately support dividend growth. We have just completed the regulatory review process in the United States, Canada and Australia and expect to close the transaction on May 2, 2016. Teams from both companies have been engaged in integration planning for several months, and we now look forward to executing on these plans to bring the two global platforms together and facilitate a smooth transition.

Last, and most importantly, cash generation is an important metric as it supports growth in dividends and investment. On a standalone basis, our durable cash flow coupled with the Transformation initiative allows us to markedly increase our dividend per share between now and 2018 and grow it at approximately 4% annually, thereafter. And with Recall, our minimum dividend per share is expected to deliver 23% growth between 2015 and 2018 – all without issuing equity beyond shares issued to buy Recall and whilst continuing to invest in the business for durable long-term growth.

Looking ahead to 2016, despite continued headwinds from the strong U.S. dollar, our growth expectations on a constant dollar basis remain consistent with our long-term plans. Importantly, these plans are underpinned by nearly $1.5 billion of storage-related net operating income, which is distinguished by its inherent durability and consistent operating performance.

As we execute our strategy to extend that durability and capture opportunities in adjacent businesses and emerging markets, we are truly appreciative of the continued support of our customers, stockholders and more than 20,000 Mountaineers around the globe.

Yours sincerely,



William L. Meaney, President and Chief Executive Officer

## CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

We have made statements in this Annual Report that constitute "forward-looking statements" as that term is defined in the Private Securities Litigation Reform Act of 1995 and other securities laws. These forward-looking statements concern our operations, economic performance, financial condition, goals, beliefs, future growth strategies, investment objectives, plans and current expectations, such as our (1) commitment to future dividend payments, (2) expected growth in volume of records stored with us from existing customers, (3) expected 2016 consolidated revenue internal growth rate and capital expenditures, (4) expected target leverage ratio, (5) proposed acquisition of Recall Holdings Limited ("Recall") pursuant to the Scheme Implementation Deed, as amended (the "Recall Agreement"), with Recall (the "Recall Transaction"), including our expected consideration to be paid to Recall shareholders and expected total cost to close the Recall Transaction and to integrate the combined companies, and (6) expected cost savings associated with the Transformation Initiative (as defined herein). These forward-looking statements are subject to various known and unknown risks, uncertainties and other factors. When we use words such as "believes", "expects", "anticipates", "estimates" or similar expressions, we are making forward-looking statements. Although we believe that our forward-looking statements are based on reasonable assumptions, our expected results may not be achieved, and actual results may differ materially from our expectations. In addition, important factors that could cause actual results to differ from expectations include, among others:

- our ability to remain qualified for taxation as a real estate investment trust for United States federal income tax purposes ("REIT");

- the adoption of alternative technologies and shifts by our customers to storage of data through non-paper based technologies;

• changes in customer preferences and demand for our storage and information management services;

- the cost to comply with current and future laws, regulations and customer demands relating to privacy issues, as well as fire and safety standards;

- the impact of litigation or disputes that may arise in connection with incidents in which we fail to protect our customers' information;

- changes in the price for our storage and information management services relative to the cost of providing such storage and information management services;

• changes in the political and economic environments in the countries in which our international subsidiaries operate;

- our ability or inability to complete acquisitions on satisfactory terms and to integrate acquired companies efficiently;

• changes in the amount of our capital expenditures;

• changes in the cost of our debt;

• the impact of alternative, more attractive investments on dividends;

• the cost or potential liabilities associated with real estate necessary for our business;

- the performance of business partners upon whom we depend for technical assistance or management expertise outside the United States; and

- other trends in competitive or economic conditions affecting our financial condition or results of operations not presently contemplated.

In addition, with respect to the Recall Transaction, our ability to close the proposed transaction in accordance with the terms of the Recall Agreement, or at all, is dependent upon our and Recall's ability to satisfy the closing conditions set forth in the Recall Agreement, including the receipt of governmental and shareholder approvals.

Other risks may adversely impact us, as described more fully under "Item 1A. Risk Factors" of this Annual Report.

You should not rely upon forward-looking statements except as statements of our present intentions and of our present expectations, which may or may not occur. You should read these cautionary statements as being applicable to all forward-looking statements wherever they appear. Except as required by law, we undertake no obligation to release publicly the result of any revision to these forward-looking statements that may be made to reflect events or circumstances after the date hereof or to reflect the occurrence of unanticipated events. Readers are also urged to carefully review and consider the various disclosures we have made in this document, as well as our other periodic reports filed with the SEC.

## Item 1. Business.

## Business Overview

We store records, primarily physical records and data backup media, and provide information management services that help organizations around the world protect their information, lower storage rental costs, comply with regulations, enable corporate disaster recovery, and better use their information for business advantages, regardless of its format, location or life cycle stage. We offer comprehensive records and information management services and data management services, along with the expertise and experience to address complex storage and information management challenges such as rising storage rental costs, and increased litigation, regulatory compliance and disaster recovery requirements. Founded in an underground facility near Hudson, New York in 1951, Iron Mountain Incorporated, a Delaware corporation, has more than 170,000 customers in a variety of industries in 37 countries around the world. We currently provide storage and information management services to legal, financial, healthcare, insurance, life sciences, energy, businesses services and government organizations, including approximately 94% of the Fortune 1000. As of December 31, 2015, we employed more than 20,000 people.

Now in our 65th year, we have experienced tremendous growth, particularly since successfully completing the initial public offering of our common stock in February 1996, at which time we operated fewer than 85 facilities (6 million square feet) with limited storage and information management service offerings and annual revenues of approximately $104.0 million. We are now a global enterprise providing storage and a broad range of related records and information management services to customers in markets around the world with approximately 1,100 facilities (69.9 million square feet) and total revenues of more than $3.0 billion for the year ended December 31, 2015. We are listed on the New York Stock Exchange (the "NYSE"). We are a constituent of the Standard & Poor's 500 Index and the MSCI REIT index and, as of December 31, 2015, we were number 726 on the Fortune 1000.

## REIT Conversion

Consistent with our commitment to delivering stockholder value, and supported by our strong cash flows, we initiated a stockholder payout program in February 2010 and a dividend policy under which we have paid, and in the future intend to pay, cash dividends on our common stock. In June 2012, we announced our intention to pursue REIT conversion. The conversion plan was unanimously approved by our board of directors following a thorough analysis and careful consideration of ways to maximize value through alternative financing, capital and tax strategies. We have been organized and operating as a REIT effective for our taxable year beginning January 1, 2014. Since May 2012, we have returned $2.5 billion of capital to stockholders including $1.4 billion in cash and $1.1 billion in our common stock.

In connection with our conversion to a REIT and, in particular, to impose ownership limitations customary for REITs, on January 20, 2015, we completed the merger with our predecessor and all outstanding shares of our predecessor's common stock were converted into a right to receive an equal number of shares of our common stock. Accordingly, references herein to our "common stock" refer to our common stock and the common stock of our predecessor, as applicable.

## Proposed Recall Acquisition

On June 8, 2015, we entered into the Recall Agreement with Recall to acquire Recall by way of recommended court approved Scheme of Arrangement (the "Scheme"). The Recall Transaction, if consummated, would accelerate our already successful growth strategy. The combined company's broader footprint, stronger infrastructure, exposure to high growth emerging markets and small to mid-size enterprise customers and increased economies of scale will be well suited to address unmet document storage and information management needs around the globe. Completion of the Scheme is subject to customary closing conditions, as described more fully in "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations" and Note 6 to Notes to Consolidated Financial Statements included in this Annual Report.

## 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 (unvended) or 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 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. Ultimately, 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) concerns over possible future litigation and the resulting increases in volume and holding periods of records; (3) the continued proliferation of data processing technologies such as personal computers and networks; (4) inexpensive document producing technologies such as desktop publishing software and desktop printing; (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; and (7) the need to keep backup copies of certain records in off-site locations for business continuity purposes in the event of disaster.

## Business Strategy

## Overview

We have transitioned from a growth strategy driven primarily by acquisitions of storage and information management services companies to a strategy that targets multiple sources of revenue growth. Our current 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 and the Asia Pacific region, 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. However, any increases in our international profit margins will be limited as we continue to make acquisitions in new emerging markets.

Storage rental is the key driver of our economics and allows us to expand our relationships with our customers through value-added services that flow from storage rental. Consistent with our overall strategy, we are focused on increasing incoming volumes on a global basis. There are multiple sources of new volumes available to us, and these sources inform our growth investment strategy. Our investments in sales and marketing support sales to new customers that do not currently outsource some or all of their storage and information management needs, as well as increased volumes from existing customers. We also expect to invest in acquisitions of customer relationships and storage and information management services businesses. In our developed markets, we expect that these acquisitions will primarily be fold-in acquisitions designed to optimize the utilization of existing assets, expand our presence and better serve customers. We also expect to use acquisitions to expand our presence in attractive, higher growth emerging markets. Finally, we continue to pursue new rental streams through 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 and data management services. We have the expertise and experience to address complex storage and information management challenges, such as rising storage rental costs and increased litigation, regulatory compliance and disaster recovery requirements. 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 enhancing our 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, and developing adjacent businesses and real estate. We continue to expand our portfolio of products and services, based on our customers' evolving requirements. Adding new products and services allows us to strengthen our existing customer relationships and attract new customers in previously untapped markets.

## Growth from Existing and New Customers

Our existing customers' storage of physical records contributes to the growth of storage rental and certain records and information management services revenues because, on average, our existing customers generate additional records at a faster rate than old records are destroyed or permanently removed. The absolute number of new document storage cartons from our existing customers has been consistent in the past four years, and we anticipate that this level will be sustained, although the rate of growth is slightly declining, given the continued growth in our total records volume. In order to maximize growth opportunities from existing customers, we seek to maintain high levels of customer retention by providing premium customer service.



Our sales coverage model is designed to identify and capitalize on incremental revenue opportunities by strategically allocating our sales resources to our customer base and selling additional storage, records and information management services and products in new and existing markets. Our sales force is dedicated to three primary objectives: (1) establishing new customer account relationships; (2) generating additional revenue by expanding existing customer relationships globally; and (3) expanding new and existing customer relationships by effectively selling a wide array of related services and products. 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 federal vertical market segments.

## Growth through Acquisitions

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 acquisition activity in the industry. Acquisitions were a fast and efficient way to achieve scale, expand geographically and broaden service offerings. After 2004, acquisition activity was reduced as we focused on integrating these recent 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, many of which are small, continue to exist, and we expect to continue to pursue acquisition of these businesses where we believe they 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. Occasionally, however, we may be presented with the opportunity to acquire one of the larger businesses in these markets and will evaluate each opportunity with a focus on return on invested capital and the creation of stockholder value. Such was the case with our acquisition in October 2013 of Cornerstone Records Management, LLC and its affiliates.

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

The experience, depth and strength of local management are particularly important in our emerging market 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, 2015, we operated in 37 countries. These transactions have taken, and may continue to take, the form of acquisitions of an entire business or controlling or minority investments 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. The 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 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 to acquire full ownership of each business in which we make a joint venture investment. We now own more than 98% of our international operations, measured as a percentage of consolidated revenues.

Our international 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.



## 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 all 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, or Document Management Solutions ("DMS"), data restoration projects, fulfillment services, consulting services, technology escrow services, product sales (including specially designed storage containers and related supplies), and recurring project revenues. Shredding consists primarily of the scheduled collection and shredding of records and documents generated by business operations and the sale of recycled paper resulting from shredding services.

## 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 as of the year ended December 31, 2015, 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 in cartons packed by the customer for long periods of time with limited activity. For some customers we store individual files on an open shelf basis, and these files are typically more active.

Physical records may also include critical or irreplaceable data such as master audio and video recordings, 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. 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 of backup computer media as part of corporate disaster recovery, including digital content repository systems to house, distribute, and archive key media assets, and (ii) 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. 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 offset 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.

## 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 extensive 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, 2015, our courier fleet consisted of approximately 3,700 owned or leased vehicles. Our other services include information destruction services (primarily secure shredding), DMS, Compliant Records Management and Consulting Services, Health Information Storage and Management Solutions, Entertainment Services, Energy Data Services, Discovery Services and other ancillary services.

## Information Destruction Services

Our information destruction services consist primarily of physical secure shredding operations and typically include the scheduled pick-up of loose office records that customers accumulate in specially designed secure containers we provide. 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 and Latin America.

## Document Management Solutions (DMS)

The focus of our DMS 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 DMS services 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 DMS services 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.



Other services we provide include recurring project work, which involves 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 offtsite 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 and professional consulting services.

Until December 2014, our Other International Business segment offered Destruction in Australia.



Our Corporate and Other Business segment primarily consists of our data center and fine art storage businesses in the United States, the primary product offerings of our Adjacent Business operating segment (which was formerly referred to as our Emerging Business operating segment), as well as costs related to executive and staff functions, including finance, human resources and information technology, which benefit the enterprise as a whole. These costs are primarily related to the general management of these functions on a corporate level and the design and development of programs, policies and procedures that are then implemented in the individual segments, with each segment bearing its own cost of implementation. Our Corporate and Other Business segment also includes stock-based employee compensation expense associated with all stock options, restricted stock, restricted stock units, performance units and shares of stock issued under our employee stock purchase plan.

ABOs, such as our data center and fine art storage businesses, are prospective business lines that we consider investing in to grow and diversify our business. We are seeking businesses with long-term, recurring revenue, 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. We have developed an innovation process that enables us to cautiously and effectively develop these ABOs to leverage our capabilities. If we are able to demonstrate success and meet return thresholds, we may potentially 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 scrap these opportunities, consistent with our disciplined approach to capital allocation.

With respect to our data center business, we believe that the growth rate of critical digital information is accelerating, driven in part by the use of the Internet as a distribution and transaction medium. The rising cost and increasing importance of storing and managing digital information, coupled with the increasing availability of telecommunications bandwidth at lower costs, may create meaningful opportunities for us to provide solutions to our customers with respect to their digital records storage and management challenges.

A more recent example of an ABO is our fine art storage business. 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 will build on our expertise in storing, protecting and managing high-value items and supports our strategy to leverage our real estate network to accelerate growth. The fine art storage industry is a growing, but fragmented, industry marked by increasing international interest and changes in acquisition and purchasing habits by collectors and museums. 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 have the fine art storage industry poised for significant growth.



## Our Business Fundamentals

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

- Recurring Revenues. We derive a majority of our consolidated revenues from fixed periodic, usually monthly, storage rental fees charged to customers based on the volume of their records stored. Once a customer places physical records in storage with us, and until those records are destroyed or permanently removed (for which we typically receive a service fee), we receive recurring payments for storage rental without incurring additional labor or marketing expenses or significant capital costs. Similarly, contracts for the storage of electronic backup media involve primarily fixed monthly rental payments. This stable and growing storage rental revenue base also provides the foundation for increases in service revenues and 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 Racing Utilization"). As of December 31, 2015, our Total Building Utilization and Total Racing Utilization were approximately 84% and 92%, respectively, for our records management business and our Total Building Utilization and Total Racing Utilization were approximately 69% and 81%, respectively, for our data management business.

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 ("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, as well as customer satisfaction with our services and contractual net price increases. The absolute number of new document storage cartons from our existing customers has been consistent in the past four 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 6%, 4% and 2% on a global basis for 2013, 2014 and 2015, respectively.

- Diversified and Stable Customer Base. As of December 31, 2015, we had more than 170,000 customers in a variety of industries in 37 countries around the world. We currently provide storage and information management services to legal, financial, healthcare, insurance, life sciences, energy, businesses services and government organizations, including approximately 94% of the Fortune 1000. No single customer accounted for as much as 1% of our consolidated revenues in any of the years ended December 31, 2013, 2014 and 2015. For each of the three years 2013 through 2015, 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 generally generate cash flows to support our dividends, maintain our operations and infrastructure and invest in core growth opportunities. We plan on funding acquisitions, ABO investments and real estate investments primarily through incremental borrowing at a targeted leverage ratio and/or proceeds from the issuance of equity, dependent on market conditions. 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 2016:

## Real Estate:

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

• 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:

• 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 new 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.

• 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 operational support initiatives such as sales and marketing and information technology projects to support infrastructure requirements, or Non-Real Estate Maintenance.

The following table presents our capital spend for 2013, 2014 and 2015 organized by the type of the spending as described above:

<table><tr><td colspan="4">Year Ended December 31,</td></tr><tr><td>2013</td><td>2014</td><td>2015</td><td></td></tr><tr><td>Investment</td><td>$ 135,708</td><td>$ 199,663</td><td>$ 170,742</td></tr><tr><td>Maintenance</td><td>61,863</td><td>57,574</td><td>52,826</td></tr><tr><td>Total Real Estate Capital Spend</td><td>197,571</td><td>257,237</td><td>223,568</td></tr><tr><td>Non-Real Estate:</td><td></td><td></td><td></td></tr><tr><td>Investment</td><td>91,792</td><td>55,991</td><td>47,964</td></tr><tr><td>Maintenance</td><td>22,644</td><td>19,527</td><td>23,396</td></tr><tr><td>Total Non-Real Estate Capital Spend</td><td>114,436</td><td>75,518</td><td>71,360</td></tr><tr><td>Total Capital Spend (on accrual basis)</td><td>312,007</td><td>332,755</td><td>294,928</td></tr><tr><td>Net increase/(decrease) in prepaid capital expenditures</td><td>3,327</td><td>(2,455)</td><td>(362)</td></tr><tr><td>Net (increase)/decrease accrued capital expenditures</td><td>(28,039)</td><td>31,624</td><td>(4,317)</td></tr><tr><td>Total Capital Spend (on cash basis)</td><td>$ 287,295</td><td>$ 361,924</td><td>$ 290,249</td></tr></table>

## Competition

We are a global leader in the physical storage and information management services industry with operations in 37 countries as of December 31, 2015. We compete with our current and potential customers' internal storage and information management services capabilities.



We also compete with numerous storage and information management services providers in every geographic area where we operate. The physical storage and information management services industry is highly competitive and includes thousands of competitors in North America and around the world. We believe that competition for customers is based on price, reputation for reliability, quality and security of storage, quality of service and scope and scale of technology, and we believe we generally compete effectively in each of these areas.

## Alternative Technologies

We derive most of our revenues from rental fees for the storage of physical records and computer backup tapes and from storage related services. Alternative storage technologies exist, many of which require significantly less space than physical documents and tapes, and as alternative technologies are adopted, storage related services may decline as the physical records or tapes we store become less active and more archived. To date, none of the alternative technologies has replaced physical documents as the primary means for storing information. We continue to provide, primarily through partnerships, additional services such as online backup, designed to address our customers' need for efficient, cost-effective, high-quality solutions for electronic records and storage and information management.

## Employees

As of December 31, 2015, we employed more than 8,000 employees in the United States and more than 12,000 employees outside of the United States. At December 31, 2015, fewer than 650 employees were represented by unions in California, Illinois, Georgia and three provinces in Canada.

All union and non-union employees are generally eligible to participate in our benefit programs, which include medical, dental, life, short and long-term disability, retirement/401(k) and accidental death and dismemberment plans. Certain unionized employees in California receive these types of benefits through their unions and are not eligible to participate in our benefit programs. In addition to base compensation and other usual benefits, all full-time employees participate in some form of incentive-based compensation program that provides payments based on revenues, profits, collections or attainment of specified objectives for the unit in which they work. Management believes that we have good relationships with our employees and unions. All union employees are currently under renewed labor agreements or operating under an extension agreement.

## Insurance

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

Our customer contracts usually contain provisions limiting our liability for damages with respect to loss or destruction of, or damage to, records or information stored with us. Our liability under physical storage contracts is often limited to a nominal fixed amount per item or unit of storage, such as per cubic foot. Our liability under our DMS services and other service contracts is often limited to a percentage of annual revenue under the contract. We can provide no assurance that where we have limitation of liability provisions that they will be enforceable in all instances or would otherwise protect us from liability. Also, some of our contracts with large volume accounts and some of the contracts assumed in our acquisitions contain no such limits or contain higher limits. In addition to provisions limiting our liability, our standard storage rental and service contracts 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. While we have had relatively few disputes with our customers with regard to the terms of their customer contracts, and most disputes to date have not been material, we can give no assurance that we will not have material disputes in the future.



## 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. We therefore may be potentially liable for environmental costs and may be unable to sell, rent, mortgage or use contaminated real estate owned or leased by us. Under various federal, state and local environmental laws, we may be liable for environmental compliance and remediation costs to address contamination, if any, located at owned and leased properties as well as damages arising from such contamination, whether or not we know of, or were responsible for, the contamination, or the contamination occurred while we owned or leased the property. Environmental conditions for which we might be liable may also exist at properties that we may acquire in the future. In addition, future regulatory action and environmental laws may impose costs for environmental compliance that do not exist today.

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

## Item 1A. Risk Factors.

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

## Risks Related to the Recall Transaction

The integration of Recall will subject us to liabilities that may exist at Recall or may arise in connection with the consummation of the Recall Transaction.

Our integration with Recall may pose special risks, including one-time write-offs or restructuring charges, unanticipated costs, and the loss of key employees. There can be no assurance that our integration with Recall will be accomplished effectively or in a timely manner. In addition, our integration with Recall will subject us to liabilities (including tax liabilities) that may exist at Recall or may arise in connection with the consummation of the Recall Transaction, some of which may be unknown. Although we and our advisors have conducted due diligence on the operations of Recall, there can be no guarantee that we are aware of all liabilities of Recall. These liabilities, and any additional risks and uncertainties related to the Recall Transaction not currently known to us or that we may currently deem immaterial or unlikely to occur, could negatively impact our future business, financial condition and results of operations.

The price of our common stock and our results of operations after the Recall Transaction may be affected by factors different from those currently affecting the price of our common stock and our results of operations.

Recall's business is different in certain ways from ours, and our results of operations, as well as the price of our common stock after the Recall Transaction, may be affected by factors different from those currently affecting the results of our operations and the price of our common stock. The price of our common stock may fluctuate significantly following the Recall Transaction, including as a result of factors over which we and Recall have no control. Current stockholders may not wish to continue to invest in us if the Recall Transaction is consummated or for other reasons may wish to dispose of some or all of their shares of our common stock. If, following the consummation of the Recall Transaction, there is selling pressure on our common stock that exceeds demand at the market price, the price of our common stock could decline. In addition, if the Recall Transaction is completed, the Recall shareholders will own a significant percentage of the issued and outstanding shares of common stock of the combined company, and they may determine not to hold their shares of our common stock following the Recall Transaction, which may result in additional pressure on the price of our common stock.

We will incur significant transaction and combination-related costs in connection with the Recall Transaction.

We and Recall expect to incur significant costs associated with the Recall Transaction and combining the operations of the two companies, some of which will be paid regardless of whether we are able to complete the Recall Transaction. In this regard, we expect to incur approximately $80.0 million of costs, including advisory and professional fees, to complete the Recall Transaction (“Recall Deal Close Costs”) and approximately $300.0 million of costs to integrate Recall with our existing operations, including moving, severance, facility upgrade, REIT conversion and system upgrade costs ("Recall Integration Costs"). Despite our current estimates, it is difficult to predict the amount of these costs, and we may incur additional unanticipated costs as a consequence of difficulties arising from efforts to integrate the companies.

We will need additional debt financing, which may not be available on favorable terms, if at all, in order to consummate the Recall Transaction.

We currently anticipate that we will need to raise additional debt financing to consummate the Recall Transaction. Such additional financing may not be available on favorable terms, if at all. If we are unable to obtain sufficient financing and consummate the Recall Transaction, we may be subject to significant monetary or other damages under the Recall Agreement.

The Recall Agreement limits our ability to pursue alternatives to the Recall Transaction, and in certain instances requires payment of a reimbursement fee, which could deter a third party from proposing an alternative transaction to the Recall Transaction.

While the Recall Agreement is in effect, subject to certain limited exceptions, we are prohibited from soliciting, initiating, encouraging or entering into certain transactions, such as a merger, sale of assets or other business combination, with any third party. As a result of these limitations, we may lose opportunities to enter into a more favorable transaction than the Recall Transaction.

Moreover, under specified circumstances, we could be required to pay Recall a reimbursement fee of A$25.5 million in connection with the termination of the Recall Agreement. The reimbursement fee could deter a third party from proposing an alternative to the Recall Transaction.



The Recall Transaction is subject to conditions to closing that could result in the Recall Transaction being delayed or not completed and the Recall Agreement can be terminated in certain circumstances, each of which could negatively impact the price of our common stock and our future business and operations.

Consummation of the Recall Transaction is subject to conditions, including, among others:

• the approval by the Recall shareholders of the Recall Transaction;

- the approval of the Scheme by the Federal Court of Australia, Sydney Registry (the “Sydney Federal Court”) (or such other competent court agreed by us and Recall);

• the absence of any law, order or injunction that would prohibit, restrain or make illegal the Recall Transaction;

• the receipt of regulatory approvals;

- the approval for listing on the NYSE of our common stock to be issued in the Recall Transaction and the establishment of a secondary listing on the Australian Securities Exchange (the "ASX") to allow shareholders of Recall to trade our common stock via CHESS Depository Interests on the ASX;

- the accuracy of the representations and warranties and compliance with the respective covenants of the parties, subject to specified materiality qualifiers; and

• no events having occurred that would have a material adverse effect on Recall or us.

In addition, we and Recall each has the right, in certain circumstances, to terminate the Recall Agreement. If the Recall Agreement is terminated or any of the conditions to closing are not satisfied and, where permissible, not waived, the Recall Transaction will not be completed.

Failure to complete the Recall Transaction or any delay in the completion of the Recall Transaction or any uncertainty about the completion of the Recall Transaction may adversely affect the price of our common stock or have an adverse impact on our future business and operations.

If the Recall Transaction is not completed, our ongoing business may be adversely affected and, without realizing any of the benefits of having completed the Recall Transaction, we would be subject to a number of risks, including the following:

• negative reactions from the financial markets;

- incurring and paying significant expenses in connection with the Recall Transaction, such as Recall Deal Costs and Recall Integration Costs;

• paying a reimbursement fee of A$25.5 million if the Recall Agreement is terminated in certain circumstances; and

• paying a reimbursement fee of A$76.5 million if the Recall Agreement is terminated due to our inability to obtain the necessary antitrust/competition approvals required to consummate the Recall Transaction.

In addition, we could be subject to litigation related to any failure to complete the Recall Transaction or seeking to require us to perform our obligations under the Recall Agreement.

The exchange ratio is fixed and will not be adjusted in the event of any change in either Recall's share price or our stock price.

Subject to the terms and conditions set forth in the Recall Agreement, after the effective date of the Scheme and upon the completion of the Recall Transaction, each outstanding ordinary share of Recall will be transferred to us in exchange for the Australian dollar equivalent of US$0.50 in cash for each outstanding share of Recall common stock (the "Cash Supplement") as well as either (1) 0.1722 of a newly issued share of our common stock or (2) 8.50 Australian dollars less the Australian dollar equivalent of US$0.50 in cash for each Recall share (the "Cash Election"). The Cash Election is subject to a promotion mechanism that will cap the total amount of cash paid to Recall shareholders electing the Cash Election at 225.0 million Australian dollars (the "Cash Election Cap"). The exchange ratio is fixed and will not be adjusted for changes in the market price of either Recall shares or our shares. Changes in the price of our shares prior to completion of the Scheme may affect the market value that holders of Recall shares will receive on the date of the effective time for the Scheme. Share price changes may result from a variety of factors (many of which are beyond our or Recall's control).

If the share price of our common stock increases before the closing of the Recall Transaction, Recall shareholders will receive shares of our common stock that have a market value that is greater than the current market value of such shares. Alternatively, if the share price of our common stock decreases before the closing of the Recall Transaction, Recall shareholders will receive shares of our common stock that have a market value that is less than the current market value of such shares. Therefore, because the exchange ratio is fixed, prior to the closing of the Recall Transaction, our stockholders and Recall shareholders cannot be sure of the market value of the share consideration that will be paid to Recall shareholders upon completion of the Recall Transaction.



Obtaining required governmental and court approvals necessary to satisfy closing conditions may delay or prevent completion of the Recall Transaction or may impose material terms and conditions, including asset divestitures, which could negatively impact our ability to realize the anticipated benefits of the Recall Transaction.

Completion of the Recall Transaction is conditioned upon the receipt of certain governmental authorizations, consents, orders or other approvals, including (i) approvals, clearances, filings or expiration or termination of waiting periods required in relation to the Recall Transaction under antitrust laws of Australia, Canada, the United States, and the United Kingdom and (ii) approval by the Sydney Federal Court (or such other competent court agreed to by us and Recall). In the Recall Agreement, we agreed to offer, negotiate and agree to divestitures and/or similar restraints with respect to our Recall's businesses, services or assets, except that we are not required to agree to divestitures or similar restraints with respect to our assets or Recall's records management businesses in the United States and Canada that, in the aggregate, generated more than US$30.0 million in revenues during the twelve-month period prior to the date of the Recall Agreement (the "Divestiture Threshold"). No assurance can be given that the antitrust/competition approvals will be obtained. In the event that the Recall Agreement is terminated as a result of the failure to obtain the antitrust/competition approvals, subject to certain limited exceptions, we will be obligated to pay Recall a reimbursement fee of A$76.5 million.

Antitrust/competition approval, if obtained, is likely to be conditioned on the divestiture of certain assets in Australia, Canada, the United States and/or the United Kingdom, including the divestiture of assets in the United States and Canada that, in the aggregate, may exceed the Divestiture Threshold. If we divest more assets than we anticipated when we entered into the Recall Agreement, the benefits that we originally expected to realize from the Recall Transaction could be reduced. Moreover, to the extent that the current price of our common stock reflects an assumption that asset divestitures will be less than what may ultimately be required by antitrust/competition agencies in Australia, Canada, the United States and/or the United Kingdom in order to consummate the Recall Transaction, the price per share for our common stock could be negatively impacted.

Following the Recall Transaction, our exposure to foreign exchange translation risk will be increased.

We are currently subject to foreign exchange translation risk because we conduct business operations in several foreign countries through our foreign subsidiaries or affiliates, which conduct business in their respective local currencies. Recall conducts a significant portion of its operations outside of the United States through its foreign subsidiaries or affiliates, which also operate in their respective local currencies. Therefore, following the completion of the Recall Transaction, our international operations will account for a more significant portion of our overall operations than they do presently. Because our financial statements will continue to be presented in United States dollars subsequent to the Recall Transaction, the local currencies will be 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 intercompany balances associated with, our international storage and information management services businesses will continue to be exposed to foreign exchange rate fluctuations, and due to the Recall Transaction, our exposure to exchange rate fluctuations will increase. 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 certain circumstances, if the Recall Agreement is terminated without any payment of a termination payment by Recall, we may not be fully reimbursed for our out of pocket expenses.

Under the Recall Agreement, Recall would be required to reimburse us for our reasonable, documented out of pocket expenses actually incurred in connection with the Recall Transaction up to a maximum of $5.0 million if (1) the Recall board of directors withdraws or adversely modifies its recommendation that Recall shareholders vote in favor of the resolution to approve the Recall Transaction as a result of the report of the independent expert opining that the Recall Transaction is not in the best interests of Recall's shareholders (other than where the reason for such opinion is a Recall competing transaction) and (ii) the Recall Agreement is terminated by Recall or us prior to the Recall shareholders meeting. Given that such reimbursed expenses cannot exceed $5.0 million, we may not be fully reimbursed for our out of pocket expenses in the event of such a termination.

Our due diligence of Recall may have failed to identify key issues that could have an adverse effect on our performance and financial condition.

Before executing the Recall Agreement, we and Recall undertook a period of mutual due diligence for the purpose of negotiating the terms of the Recall Transaction. Although we and Recall decided to proceed with the Recall Transaction following that due diligence exercise, there is a risk that the due diligence undertaken was insufficient or failed to identify key issues. Furthermore, after implementation of the Recall Transaction, we will be subject to any unknown liabilities of Recall which could have an adverse effect on our performance and financial condition.



We will guarantee 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 or intends to obtain such tax opinions, based on, among other things, representations and warranties made by Recall and us. Such opinions, once accepted by Brambles, do not affect Recall's obligation to indemnify Brambles for an adverse impact on the tax-free status of such prior spin-offs. The delivery of those opinions is a condition to our obligation to consummate the Recall Transaction.

We have agreed, contingent on the consummation of the Recall Transaction, to guarantee 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 and Recall would be liable for the resulting taxes, which could be material.

## Risks Related to Us and Recall

The failure to integrate successfully Recall’s business with our business in the expected time frame would adversely affect our future results.

The success of the Recall Transaction will depend, in large part, on our ability to realize the anticipated benefits, including cost savings from combining Recall’s businesses with ours. To realize these anticipated benefits, our business and Recall’s must be successfully integrated. This integration will be complex and time-consuming. The failure to integrate successfully and to manage successfully the challenges presented by the integration process may result in us not fully achieving the anticipated benefits of the Recall Transaction.

Potential difficulties that may be encountered in the integration process include the following:

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

- conforming standards, controls, procedures and policies, business cultures and compensation structures between the entities;

- integrating personnel from the two entities while maintaining focus on developing, producing and delivering consistent, high quality services;

• consolidating corporate and administrative infrastructures;

• coordinating geographically dispersed organizations;

- potential unknown liabilities and unforeseen expenses, delays or regulatory conditions associated with the Recall Transaction;

- performance shortfalls at one or both of the entities as a result of the diversion of management's attention caused by completing the Recall Transaction and integrating the entities' operations; and

• our ability to deliver on our strategy going forward.



We will incur adverse tax consequences if the combined company following the Recall Transaction fails to qualify as a REIT for United States federal income tax purposes.

We believe that, following the Recall Transaction, we will integrate Recall's assets and operations in a manner that will allow us to timely satisfy the REIT income, asset, and distribution tests applicable to us. However, if we fail to do so, we could jeopardize or lose our qualification for taxation as a REIT, particularly if we were ineligible to utilize relief provisions set forth in the Code. For any taxable year that we fail to qualify for taxation as a REIT, we would not be allowed a deduction for distributions to our stockholders in computing our taxable income, and thus would be subject to United States federal and state income tax at the regular corporate rates on all of our United States federal and state taxable income in the manner of a regular corporation. Those corporate level taxes would reduce the amount of cash available for distribution to our stockholders or for reinvestment or other purposes, and would adversely affect our earnings. As a result, our failure to qualify for taxation as a REIT during any taxable year could have a material adverse effect upon us and our stockholders. Furthermore, unless prescribed relief provisions apply, we would not be eligible to elect REIT status again until the fifth taxable year that begins after the first year for which we failed to qualify as a REIT. Finally, even if we are able to utilize relief provisions and thereby avoid disqualification for taxation as a REIT, relief provisions typically involve paying a penalty tax in proportion to the severity and duration of the noncompliance with REIT requirements, and thus these penalty taxes could be significant in the context of noncompliance stemming from a transaction as large as the Recall Transaction.

The Recall Transaction, if completed, will dilute the ownership position of our current stockholders.

If the Recall Transaction is completed, the Recall shareholders are expected to beneficially own a significant percentage of our issued and outstanding shares of common stock. Consequently, our current stockholders will own a smaller proportion of our common stock than the proportion of common stock they owned before the Recall Transaction and, as a result, they will have less influence on our management and policies following the Recall Transaction than they now have on our management and policies.

Our and Recall's business relationships may be subject to disruption due to uncertainty associated with the Recall Transaction, which could have an adverse effect on our and Recall's results of operations, cash flows and financial position and, following the completion of the Recall Transaction, the combined company.

Parties with which we and Recall do business may experience uncertainty associated with the Recall Transaction, including with respect to current or future business relationships with us, Recall or the combined company following the completion of the Recall Transaction. Our and Recall's relationships may be subject to disruption as customers, suppliers and other persons with whom we and Recall have a business relationship may delay or defer certain business decisions or might decide to seek to terminate, change or renegotiate their relationships with us or Recall, as applicable, or consider entering into business relationships with parties other than us or Recall. These disruptions could have an adverse effect on the results of operations, cash flows and financial position of us, Recall or the combined company following the completion of the Recall Transaction, including an adverse effect on our ability to realize the expected synergies and other benefits of the Recall Transaction. The risk, and adverse effect, of any disruption could be exacerbated by a delay in the completion of the Recall Transaction or the termination of the Recall Agreement.

## 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 commencing with our 2014 taxable year; however, we can provide no assurance that we will remain qualified for taxation as a REIT. If we fail to remain qualified 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 these provisions.

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

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

- we will be subject to federal and state income tax, including any applicable alternative minimum tax, on our taxable income at regular corporate tax rates; and

- we would not be eligible to elect REIT status again until the fifth taxable year that begins after the first year for which we failed to qualify as a REIT.

Any such corporate tax liability could be substantial and would reduce the amount of cash available for other purposes.



If we fail to remain qualified for taxation as a REIT, we may need to borrow additional funds or liquidate some investments to pay any additional tax liability. Accordingly, funds available for investment and distributions to stockholders could be reduced.

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

We expect to continue paying regular quarterly distributions, and, to achieve maximum tax efficiency and retain cash to allow us to make selective discretionary investments, we currently anticipate our typical regular quarterly distributions will be based on a payment of approximately 100% of our REIT taxable income; 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 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 recognition of income 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, the creation of reserves or required debt service or amortization payments.

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

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

In order to meet the REIT distribution requirements and maintain our qualification and taxation as a REIT, or to fund capital expenditures, future growth and expansion initiatives, we may need to borrow funds, sell assets or raise equity, even if the then-prevailing market conditions are not favorable for these borrowings, sales or offerings. Any insufficiency of our cash flows to cover our REIT distribution requirements could adversely impact our ability to raise short- and long-term debt, to sell assets, or to offer equity securities in order to fund distributions required to maintain our qualification and taxation as a REIT. Furthermore, the REIT distribution requirements may increase the financing we need to fund capital expenditures, future growth and expansion initiatives. This would increase our indebtedness. An increase in our outstanding debt could lead to a downgrade of our credit rating. A downgrade of our credit rating could negatively impact our ability to access credit markets. Further, certain of our current debt instruments limit the amount of indebtedness we and our subsidiaries may incur. Additional financing, therefore, may be unavailable, more expensive or restricted by the terms of our outstanding indebtedness. For a discussion of risks related to our substantial level of indebtedness, see "Risks Relating to Our Indebtedness."

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

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



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

At any time, the federal income tax laws governing REITs or the administrative interpretations of those laws may be amended. Federal and state tax laws are constantly under review by persons involved in the legislative process, the United States Internal Revenue Service (the "IRS"), the United States Department of the Treasury and state taxing authorities. Changes to the tax laws, regulations and administrative interpretations, which may have retroactive application, could adversely affect us. In addition, some of these changes could have a more significant impact on us as compared to other REITs due to the nature of our business and our substantial use of taxable REIT subsidiaries ("TRSs"). We cannot predict with certainty whether, when, in what forms, or with what effective dates, the tax laws, regulations and administrative interpretations applicable to us may be changed.

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

To remain qualified for taxation as a REIT for federal income tax purposes, we must continually satisfy tests concerning, among other things, the sources of our income, the nature and diversification of our assets and the amounts we distribute to our stockholders. Thus, compliance with these tests may require us to refrain from certain activities and may hinder our ability to make certain attractive investments, including the purchase of non-REIT qualifying operations or assets, the expansion of non-real estate activities, and investments in the businesses to be conducted by our TRSs, and to that extent limit our opportunities and our flexibility to change our business strategy. 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. Beginning in our 2018 taxable year, no more than 20% of the value of the assets of a REIT may be represented by securities of one more TRS 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.

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

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

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

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

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 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. Beginning with our 2018 taxable year, 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.



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 alternative minimum taxes, 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 qualification for taxation as a REIT.

Our information management services businesses are conducted through wholly owned TRSs because these activities could generate nonqualifying REIT income as currently structured and operated. The income of our domestic TRSs will continue to be subject to federal and state corporate income taxes. In addition, we and our subsidiaries continue to be subject to foreign income taxes in jurisdictions in which we have business operations or a taxable presence, regardless of whether assets are held or operations are conducted through subsidiaries disregarded for federal income tax purposes or TRSs. Any of these taxes would decrease our earnings and our available cash.

We will also be subject to a federal corporate level tax at the highest regular corporate tax rate (currently 35%) on gain recognized from a sale of a REIT asset where our basis in the asset is determined by reference to the basis of the asset in the hands of a C corporation (such as (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 a QRS following the liquidation or other conversion of a former TRS). This 35% tax is generally applicable to any disposition of such an asset during the five-year period after the date we first owned the asset as a REIT asset (e.g., January 1, 2014 in the case of REIT assets we held at the time of our REIT conversion), to the extent of the built-in-gain based on the fair market value of such asset on the date we first held the asset as a REIT asset. In addition, depreciation recapture income that we expect to recognize in connection with the Recall Transaction as a result of accounting method changes that we will make will be fully subject to this 35% tax.

In addition, the IRS and any state or local tax authority may successfully assert liabilities against us for corporate income taxes for our pre-REIT period, in which case we will owe these taxes plus applicable interest and penalties, if any. Moreover, any increase in taxable income for these pre-REIT periods will likely result in an increase in pre-REIT accumulated earnings and profits, which could cause us to pay an additional taxable distribution to our stockholders after the relevant determination.

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 to acquire or carry real estate assets and income from certain currency hedging transactions related to our non-United States operations, as well as income from qualifying counteracting hedges do not constitute "gross income" for purposes of the REIT gross income tests. To the extent that we enter into other types of hedging transactions, the income from those transactions is likely to be treated as nonqualifying income for purposes of the REIT gross income tests. As a result of these rules, we may need to limit our use of advantageous hedging techniques or implement those hedges through our TRSs. This could increase the cost of our hedging activities because our TRSs would be subject to tax on income or gains resulting from hedges entered into by them or 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 taxable income in the TRSs.



We have limited experience operating as a REIT, which may adversely affect our financial condition, results of operations, cash flow, per share trading price of our common stock, ability to forecast dividends and ability to satisfy debt service obligations.

We began operating as a REIT on January 1, 2014 and, as such, have limited operating history as a REIT. In addition, prior to January 1, 2014 our senior management team had no prior experience operating a REIT. We can provide no assurance that our past experience has sufficiently prepared us to operate successfully as a REIT. Our inability to operate successfully as a REIT, including the failure to remain qualified for taxation as a REIT, could adversely affect our business, financial condition and results of operations.

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

Qualifying distributions payable by corporations to individuals, trusts and estates that are United States stockholders are currently eligible for federal income tax at preferential rates. Distributions payable by REITs, in contrast, generally are not eligible for the preferential rates. The preferential rates applicable to regular corporate distributions could cause investors who are individuals, trusts and estates to perceive investments in REITs to be relatively less attractive than investments in the stock of non-REIT corporations that pay distributions, which could adversely affect the value of the stock of REITs, including 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 elect to be taxed as a REIT. In addition, rents from "affiliated tenants" will not qualify as qualifying REIT income if we own 10% or more by vote or value of the customer, whether directly or after application of attribution rules under the Code. Subject to certain exceptions, our certificate of incorporation prohibits any stockholder from owning, beneficially or constructively, more than (i) 9.8% in value of the outstanding shares of all classes or series of our capital stock or (ii) 9.8% in value or number, whichever is more restrictive, of the outstanding shares of any class or series of our capital stock. We refer to these restrictions collectively as the "ownership limits" and we included them in our certificate of incorporation to facilitate our compliance with REIT tax rules. The constructive ownership rules under the Code are complex and may cause the outstanding stock owned by a group of related individuals or entities to be deemed to be constructively owned by one individual or entity. As a result, the acquisition of less than 9.8% of our outstanding common stock (or the outstanding shares of any class or series of our capital stock) by an individual or entity could cause that individual or entity or another individual or entity to own constructively in excess of the relevant ownership limits. Any attempt to own or transfer shares of our common stock or of any of our other capital stock in violation of these restrictions may result in the shares being automatically transferred to a charitable trust or may be void. Even though our certificate of incorporation contains the ownership limits, there can be no assurance that these provisions will be effective to prevent our qualification for taxation as a REIT from being jeopardized, including under the affiliated tenant rule. Furthermore, there can be no assurance that we will be able to monitor and enforce the ownership limits. If the restrictions in our certificate of incorporation are not effective and as a result we fail to satisfy the REIT tax rules described above, then absent an applicable relief provision, we will fail to remain qualified for taxation as a REIT.

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

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

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



## Operational Risks

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

We derive most of our revenues from rental fees for the storage of physical records and computer backup tapes and from storage related services. Alternative storage technologies exist, many of which require significantly less space than physical records and tapes, and as alternative technologies are adopted, storage related services may decline as the physical records or tapes we store become less active and more archived. We can provide no assurance that our customers will continue to store most or a portion of their records as paper documents or in tape format. The adoption of alternative technologies may also result in decreased demand for services related to the paper documents and tapes we store. A significant shift by our customers to storage of data through non-paper or tape-based technologies, whether now existing or developed in the future, could adversely affect our businesses.

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

Our records management service revenue growth is being negatively impacted by declining activity rates as stored records are becoming less active. The amount of information available to customers through the Internet or their own information systems has been steadily increasing in recent years. 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, thereby reducing their service activity levels. At the same time many of our costs related to records 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 revenue, our operating results could be adversely affected.

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

We have experienced pricing pressure in recent years as some customers have become more cost conscious with respect to their information management expenditures. Some customers have taken actions designed to reduce costs associated with the retention of documents, including reducing the volume of documents they store and adopting more aggressive destruction practices. If we are unable to increase pricing over time, or if rates of destruction of documents stored with us increase substantially, particularly in our developed and slower growing markets, our financial condition and results of operations would be adversely affected.



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

In reaction to publicized incidents in which electronically stored information has been lost, illegally accessed or stolen, almost all states in the United States have adopted breach of data security statutes or regulations that require notification to consumers if the security of their personal information is breached, and, in 2015, many states expanded the scope of their data breach notifications laws and shortened notification timelines. Some states in the United States have adopted regulations requiring every company that maintains or stores personal information to adopt a comprehensive written information security program. In addition, certain United States federal laws and regulations affecting financial institutions, health care providers and plans and others impose requirements regarding the privacy and security of information maintained by those institutions as well as notification to persons whose personal information is accessed by an unauthorized third party. Some of these laws and regulations provide for civil fines in certain circumstances and require the adoption and maintenance of privacy and information security programs; our failure to be in compliance 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 114th Congress has considered and will likely consider legislation that would expand the federal data breach notification requirement beyond the financial and medical fields.

Also, an increasing number of countries have introduced and/or increased enforcement of comprehensive privacy laws, or are expected to do so. In Europe, a new data protection regulation will likely come into effect in 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 Iron Mountain, that process data of residents of members of the European Economic Area and substantially increase penalties for violations. In addition, the European Court of Justice has invalidated a decision of the European Commission that permitted our European affiliates and our European customers to transfer personal data to entities in the United States that are certified under the EU-US safe harbor framework. This decision, a failure of the European Union and the United States to agree on a new safe-harbor framework, the new regulation and laws in other countries that restrict the export of personal data may result in more customers demanding local solutions, which would increase our IT infrastructure, maintenance and support costs.

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

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

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

As of December 31, 2015, we operated 1,046 records management, off-site data protection and fine art storage facilities worldwide, including 575 in the United States. Many of these facilities were built and outfitted by third parties and added to our real estate portfolio as part of acquisitions. Some of these facilities contain fire suppression and safety features that are different from our current specifications and current standards for new facilities although we believe all of our facilities were constructed, in all material respects, in compliance with laws and regulations in effect at the time of their construction or outfitting. In some instances local authorities having jurisdiction may take the position that our fire suppression and safety features in a particular facility are insufficient and require additional measures that may involve considerable expense to us. In addition, where we determine that the fire suppression and safety features of a facility require improvement, we will develop and implement a plan to remediate the issue, although implementation may require an extended period to complete. 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.



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 with respect to loss or destruction of, or damage to, records or information stored with us. Our liability under physical storage contracts is often limited to a nominal fixed amount per item or unit of storage, such as per cubic foot and our liability under our DMS and other service contracts is often limited to a percentage of annual revenue under the contract; however, some of our contracts with large volume accounts and some of the contracts assumed in our acquisitions contain no such limits or contain higher limits. We cannot provide assurance that where we have limitation of liability provisions they 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 standard storage rental and service contracts 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 with regard to 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. 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.

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.

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

International operations may pose unique risks.

As of December 31, 2015, we provided services in 36 countries outside the United States. As part of our growth strategy, we expect to continue to acquire or invest in storage and information management services businesses in select foreign markets, including countries where we do not currently operate. International operations are subject to numerous risks, including:

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

• the volatility of certain foreign economies in which we operate;

• political uncertainties;

• unforeseen liabilities, particularly within acquired businesses;

• costs and difficulties associated with managing international operations of varying sizes and scale;

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

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

• cultural differences and differences in business practices and operating standards; and

• foreign currency fluctuations.

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



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 operate 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 storage and information management services businesses are exposed to foreign exchange rate fluctuations, and as we have expanded our international operations, our exposure to exchange rate fluctuations has increased. Upon translation, operating results may differ materially from expectations, and significant shifts in foreign currencies can impact our short-term results, as well as our long-term forecasts and targets. In addition, because we intend to distribute 100% of our REIT taxable income to our stockholders, and any exchange rate fluctuations may negatively impact our REIT taxable income, our distribution amounts (including the classification of our distributions as nonqualified ordinary dividends, qualified ordinary dividends or return of capital, as described more fully in "Item 5. Market 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.

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

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

- acquisition and occupancy costs that make it difficult to meet anticipated margins and difficulty locating suitable facilities due to a relatively small number of available buildings having the desired characteristics in some real estate markets;

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

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

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

Some of our current and formerly owned or leased properties were previously used by entities other than us for industrial or other purposes, or were affected by waste generated from nearby properties, that involved the use, storage, generation and/or disposal of hazardous substances and wastes, including petroleum products. In some instances this prior use involved the operation of underground storage tanks or the presence of asbestos-containing materials. Where we are aware of environmental conditions that require remediation, we undertake appropriate activity, in accordance with all legal requirements. Although we have from time to time conducted limited environmental investigations and remedial activities at some of our former and current facilities, we have not undertaken an in-depth environmental review of all of our properties. 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 could disrupt our operations and adversely affect our reputation and results of operations.

Unexpected events, including fires or explosions at our facilities, natural disasters such as hurricanes and earthquakes, war or terrorist activities, unplanned power outages, supply disruptions and failure of equipment or systems, could adversely affect our reputation and results of operations. Our customers rely on us to securely store and timely retrieve their critical information, and these events could result in customer service disruption, physical damage to one or more key operating facilities and the information stored in those facilities, the temporary closure of one or more key operating facilities or the temporary disruption of information systems, each of which could negatively impact our reputation and results of operations. During the past several years we have seen an increase in severe storms and hurricanes and our key facilities in Florida and other coastal areas in particular 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 information technology systems or security breaches involving us could negatively impact our reputation, particularly if such incidents result in adverse publicity, governmental investigations or litigation. Damage to our reputation could make us less competitive, which could negatively impact our business, financial condition and results of operations.

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. We generate additional revenue through a customer surcharge when the price of diesel fuel rises above certain predetermined rates. As a result, significant declines in paper and diesel fuel prices may negatively impact our revenues and results of operations, and increases in other commodity prices, including steel, may negatively impact our results of operations.

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

Our reputation for providing secure information storage to customers is critical to the success of our business. We have previously faced attempts by unauthorized users to gain access to our information technology systems and expect to continue to face such attempts. Although we seek to prevent, detect and investigate these security incidents and have taken steps to prevent such security breaches, our information technology and network infrastructure may be vulnerable to attacks by hackers or breaches due to employee error, malfeasance or other disruptions. A successful breach of the security of our information technology systems could lead to theft or misuse of our customers' proprietary or confidential information and result in third party claims against us and reputational harm. If our reputation is damaged, we may become less competitive, which could negatively impact our businesses, financial condition or results of operations.

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

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

We face competition for customers.

We compete with multiple storage and information management services providers in all geographic areas where we operate; our current or potential customers may choose to use those competitors instead of us. We also compete, in some of our business lines, with our current and potential customers' internal storage and information management services capabilities. These organizations may not begin or continue to use us for their future storage and information management service needs.



## Risks Related to Our Indebtedness

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

We have a significant amount of indebtedness. As of December 31, 2015, our total long-term debt was approximately $4.90 billion. Our substantial indebtedness could have important consequences to our current and potential investors. These risks include:

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

• inability to adjust to adverse economic conditions;

- inability to fund future working capital, capital expenditures, acquisitions and other general corporate requirements, including possible required repurchases of our various indebtedness;

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

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

- 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; and

• restrictions on our ability to refinance our indebtedness on commercially reasonable terms.

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

Our Credit Agreement (as defined below) and our indentures contain covenants restricting or limiting our ability to, among other things:

• incur additional indebtedness;

• pay dividends or make other restricted payments;

• make asset dispositions;

• create or permit liens; and

• make acquisitions and other investments.

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

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

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

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

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



## Acquisition and Expansion Risks

Elements of our strategic growth plan involve inherent risks.

As part of our strategic growth plan, we expect to invest in new business strategies, products, services, technologies and geographies, including 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 2013 we expanded our entry into the data center market by leasing wholesale and retail colocation space in our underground facility in Pennsylvania, and in 2014 we opened our first regional data center in Massachusetts, each of which required a significant capital commitment. 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.

Failure to manage our growth may impact operating results.

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. 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 balance sheet 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 the Asia Pacific region to a lesser extent. We have entered into joint ventures and 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/markets where we currently do not operate.

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 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.

Item 1B. Unresolved Staff Comments.

None.



## Item 2. Properties.

As of December 31, 2015, we conducted operations through 860 leased facilities and 277 owned facilities. Our facilities are divided among our reportable segments as follows: North American Records and Information Management Business (605), North American Data Management Business (58), Western European Business (152), Other International Business (306) and Corporate and Other Business (16). These facilities contain a total of 69.9 million square feet of space. A breakdown of owned and leased facilities by country (and by state within the United States) is listed below:

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

See Note 10 to the Notes to the Consolidated Financial Statements included in this Annual Report for information regarding our minimum annual lease commitments.

See Schedule III—Schedule of Real Estate and Accumulated Depreciation in this Annual Report for information regarding the cost, accumulated depreciation and encumbrances associated with our owned real estate.



## Item 3. Legal Proceedings.

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. In the opinion of management, no material legal proceedings are pending to which we, or any of our properties, are subject.

## Item 4. Mine Safety Disclosures.

None.



## PART II

Item 5. Market For Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities.

Our common stock is traded on the NYSE under the symbol "IRM." The following table sets forth the high and low sale prices on the NYSE, for the years 2014 and 2015:

<table><tr><td rowspan="2"></td><td colspan="3">Sale Prices</td></tr><tr><td>High</td><td>Low</td><td></td></tr><tr><td>2014</td><td></td><td></td><td></td></tr><tr><td>First Quarter</td><td>$ 30.48</td><td>$ 25.74</td><td></td></tr><tr><td>Second Quarter</td><td>31.15</td><td>25.95</td><td></td></tr><tr><td>Third Quarter</td><td>37.10</td><td>31.17</td><td></td></tr><tr><td>Fourth Quarter</td><td>40.41</td><td>31.11</td><td></td></tr><tr><td>2015</td><td></td><td></td><td></td></tr><tr><td>First Quarter</td><td>$ 41.53</td><td>$ 35.60</td><td></td></tr><tr><td>Second Quarter</td><td>38.49</td><td>30.95</td><td></td></tr><tr><td>Third Quarter</td><td>32.25</td><td>26.49</td><td></td></tr><tr><td>Fourth Quarter</td><td>32.35</td><td>25.99</td><td></td></tr></table>

The closing price of our common stock on the NYSE on February 19, 2016 was $28.95. As of February 19, 2016, there were 407 holders of record of our common stock.

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

On September 15, 2014, we announced the declaration by our board of directors of a special distribution of $700.0 million (the "Special Distribution"), payable to stockholders of record as of September 30, 2014 (the "Record Date"). The Special Distribution represented the remaining amount of our undistributed earnings and profits attributable to all taxable periods ending on or prior to December 31, 2013, which in accordance with tax rules applicable to REIT conversions, we were required to pay to our stockholders on or before December 31, 2014 in connection with our conversion to a REIT. The Special Distribution also included certain items of taxable income that we recognized in 2014, such as depreciation recapture in respect of accounting method changes commenced in our pre-REIT period as well as foreign earnings and profits recognized as dividend income. The Special Distribution followed an initial special distribution of $700.0 million paid to stockholders in November 2012.

The Special Distribution was paid on November 4, 2014 (the "Payment Date") to stockholders of record as of the Record Date in a combination of common stock and cash. Stockholders had the right to elect to be paid their pro rata portion of the Special Distribution in all common stock or all cash, with the total cash payment to stockholders limited to no more than $140.0 million, or 20% of the total Special Distribution, not including cash paid in lieu of fractional shares. Based on stockholder elections, we paid $140.0 million of the Special Distribution in cash, not including cash paid in lieu of fractional shares, with the balance paid in the form of common stock. Our shares of common stock were valued for purposes of the Special Distribution based upon the average closing price on the three trading days following October 24, 2014, or $35.55 per share, and as such, we issued approximately 15.8 million shares of common stock in the Special Distribution. These shares impact weighted average shares outstanding from the date of issuance, and thus impact our earnings per share data prospectively from the Payment Date.

In November 2014, our board of directors declared a distribution of $0.255 per share (the "Catch-Up Distribution") payable on December 15, 2014 to stockholders of record on November 28, 2014. Our board of directors declared the Catch-Up Distribution because our cash distributions paid from January 2014 through July 2014 were declared and paid before our board of directors had determined that we would elect REIT status effective January 1, 2014 and were lower than they otherwise would have been if the final determination to elect REIT status effective January 1, 2014 had been prior to such distributions.



In 2014 and 2015, our board of directors declared the following dividends:

<table><tr><td>Declaration Date</td><td>Dividend Per Share</td><td>Record Date</td><td>Total Amount (in thousands)</td><td>Payment Date</td></tr><tr><td>March 14, 2014</td><td>$ 0.2700</td><td>March 25, 2014</td><td>$ 51,812</td><td>April 15, 2014</td></tr><tr><td>May 28, 2014</td><td>0.2700</td><td>June 25, 2014</td><td>52,033</td><td>July 15, 2014</td></tr><tr><td>September 15, 2014</td><td>0.4750</td><td>September 25, 2014</td><td>91,993</td><td>October 15, 2014</td></tr><tr><td>September 15, 2014(1)</td><td>3.6144</td><td>September 30, 2014</td><td>700,000</td><td>November 4, 2014</td></tr><tr><td>November 17, 2014(2)</td><td>0.2550</td><td>November 28, 2014</td><td>53,450</td><td>December 15, 2014</td></tr><tr><td>November 17, 2014</td><td>0.4750</td><td>December 5, 2014</td><td>99,617</td><td>December 22, 2014</td></tr><tr><td>February 19, 2015</td><td>0.4750</td><td>March 6, 2015</td><td>99,795</td><td>March 20, 2015</td></tr><tr><td>May 28, 2015</td><td>0.4750</td><td>June 12, 2015</td><td>100,119</td><td>June 26, 2015</td></tr><tr><td>August 27, 2015</td><td>0.4750</td><td>September 11, 2015</td><td>100,213</td><td>September 30, 2015</td></tr><tr><td>October 29, 2015</td><td>0.4850</td><td>December 1, 2015</td><td>102,438</td><td>December 15, 2015</td></tr></table>

(1) Represents Special Distribution.

(2) Represents Catch-Up Distribution.

During the years ended December 31, 2013, 2014 and 2015, we declared distributions to our stockholders of $206.4 million, $1,048.9 million and $402.6 million, respectively. These distributions represent approximately $1.08 per share, $5.37 per share and $1.91 per share for the years ended December 31, 2013, 2014 and 2015, respectively, based on the weighted average number of common shares outstanding during each respective year. For 2014, total amounts distributed included the Special Distribution of $700.0 million, or $3.61 per share, associated with our conversion to a REIT.

For federal income tax purposes, distributions to our stockholders are generally treated as nonqualified ordinary dividends, 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, 2013, 2014 and 2015, the dividends we paid on our common shares were classified as follows:

<table><tr><td rowspan="2"></td><td colspan="3">Year Ended December 31,</td></tr><tr><td>2013</td><td>2014</td><td>2015</td></tr><tr><td>Nonqualified ordinary dividends</td><td>0.0%</td><td>26.4%</td><td>49.3%</td></tr><tr><td>Qualified ordinary dividends</td><td>100.0%</td><td>56.4%</td><td>39.1%</td></tr><tr><td>Return of capital</td><td>0.0%</td><td>17.2%</td><td>11.6%</td></tr><tr><td></td><td>100.0%</td><td>100.0%</td><td>100.0%</td></tr></table>

## Unregistered Sales of Equity Securities and Use of Proceeds

We did not sell any unregistered securities during the three months ended December 31, 2015, nor did we repurchase any shares of our common stock during the three months ended December 31, 2015.

(1) For the year ended December 31, 2011, we recorded a non-cash goodwill impairment charge of $46.5 million in our Continental Western Europe reporting unit, which is a component of the Western European Business segment.



(2) Adjusted OIBDA and Adjusted OIBDA Margin are non-GAAP measures. Adjusted OIBDA is defined as operating income before depreciation, amortization, intangible impairments, (gain) loss on disposal/write-down of property, plant and equipment, net (excluding real estate), Recall Costs (as defined below) and REIT Costs (as defined below). Adjusted OIBDA Margin is calculated by dividing Adjusted OIBDA by total revenues. For a more detailed definition and reconciliation of Adjusted OIBDA and a discussion of why we believe these non-GAAP measures provide relevant and useful information to our current and potential investors, see "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations—Non-GAAP Measures" of this Annual Report.

(3) We have adopted the provisions of Accounting Standards Update No. 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs (“ASU 2015-03”) as of December 31, 2015. ASU 2015-03 requires debt issuance costs to be presented in the balance sheet as a reduction of the related debt liability rather than an asset. The adoption of ASU 2015-03 did not materially impact our consolidated financial position or results of operations. Prior period amounts for all years presented above were reclassified to conform to the current period presentation. Total assets and total long-term debt (including current portion of long-term debt) at December 31, 2011, 2012, 2013 and 2014 have been reduced by $35.8 million, $43.9 million, $45.6 million and $47.1 million, respectively, to reflect the adoption of ASU 2015-03.

On June 8, 2015, we entered into the Recall Agreement with Recall to acquire Recall by way of the Scheme. Under the terms of the Recall Agreement, Recall shareholders are entitled to receive the Cash Supplement as well as either (1) 0.1722 shares of our common stock for each Recall share or (2) the Cash Election. The Cash Election is subject to the Cash Election Cap. Amounts paid to Recall shareholders that represent the Cash Supplement are excluded from the calculation of the Cash Election Cap. Assuming a sufficient number of Recall shareholders elect the Cash Election such that we pay the Cash Election Cap, we expect to issue approximately 50.7 million shares of our common stock and, based on the exchange rate between the United States dollar and the Australian dollar as of February 19, 2016, pay approximately US$323.0 million to Recall shareholders in connection with the Recall Transaction which, based on the closing price of our common stock as of February 19, 2016, would result in a total purchase price to Recall shareholders of approximately $1,791.0 million. Completion of the Scheme is subject to customary closing conditions, including among others, (i) approval by Recall shareholders of the Scheme by the requisite majority under the Australian Corporations Act, (ii) expiration or earlier termination of any applicable waiting period and receipt of regulatory consents, approvals and clearances, in each case, under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and under relevant antitrust/competition and foreign investment legislation in other relevant jurisdictions, (iii) the absence of any final, non-appealable order, decree or law preventing, making illegal or prohibiting the completion of the Recall Transaction, (iv) approval from the NYSE to the listing of additional shares of our common stock to be issued in the Recall Transaction, (v) the establishment of a secondary listing on the ASX to allow Recall shareholders to trade our common stock via CHESS Depository Interests on the ASX, (vi) Recall's delivery of tax opinions in accordance and in compliance with certain tax matter agreements to which Recall is a party and (vii) no events having occurred that would have a material adverse effect on Recall or us. We continue to work toward closing of the Recall Transaction and related integration planning.

We currently estimate total operating and capital 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 approximately $80.0 million of Recall Deal Close Costs and approximately $300.0 million of Recall Integration Costs. Of these amounts, approximately $47.1 million was incurred through December 31, 2015 ($24.7 million of Recall Deal Close Costs and $22.4 million of Recall Integration Costs), including approximately $47.0 million of operating expenditures and approximately $0.1 million of capital expenditures.

## Divestitures

In December 2014, we divested our secure shredding operations in Australia, Ireland and the United Kingdom (the "International Shredding Operations") in a stock transaction for approximately $26.2 million of cash at closing. The assets sold primarily consisted of customer contracts and certain long-lived assets. We have concluded that this divestiture did not meet the requirements to be presented as a discontinued operation and, therefore, have recorded a pretax gain on sale in other (income) expense, net of approximately $6.9 million ($10.2 million, inclusive of a tax benefit) in our Consolidated Statement of Operations for the year ended December 31, 2014. Revenues from our International Shredding Operations in 2014 represented less than 1% of our consolidated revenues. The International Shredding Operations in Australia were previously included in the Other International Business segment and the International Shredding Operations in Ireland and the United Kingdom were previously included in the Western European Business segment.



During the third quarter of 2013, we implemented a plan that called for certain organizational realignments to advance our growth strategy and reduce operating costs (the “Organizational Restructuring”), which was completed in 2014. As a result of the Organizational Restructuring, we recorded charges of $23.4 million and $3.5 million for the years ended December 31, 2013 and 2014, respectively, primarily related to employee severance and associated benefits. Costs included in our results from operations associated with the Organizational Restructuring are as follows (in thousands):

<table><tr><td rowspan="2"></td><td colspan="2">Year Ended December 31,</td></tr><tr><td>2013</td><td>2014</td></tr><tr><td>Cost of sales (excluding depreciation and amortization)</td><td>$ 3,400</td><td>$ 1,228</td></tr><tr><td>Selling, general and administrative expenses</td><td>20,000</td><td>2,247</td></tr><tr><td>Total</td><td>$ 23,400</td><td>$ 3,475</td></tr></table>

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”), which is expected to be completed by the end of 2017. As a result of the Transformation Initiative, we recorded charges of $10.2 million for the year ended December 31, 2015, primarily related to employee severance and associated benefits. Costs included in our results from operations associated with the Transformation Initiative are as follows (in thousands):

<table><tr><td rowspan="2"></td><td colspan="2">Year Ended December 31, 2015</td></tr><tr><td>$</td><td>—</td></tr><tr><td>Cost of sales (excluding depreciation and amortization)</td><td>$</td><td>10,167</td></tr><tr><td>Selling, general and administrative expenses</td><td></td><td>10,167</td></tr><tr><td>Total</td><td>$</td><td>10,167</td></tr></table>

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

<table><tr><td rowspan="2"></td><td colspan="2">Year Ended December 31, 2015</td></tr><tr><td>North American Records and Information Management Business</td><td>$ 5,403</td></tr><tr><td>North American Data Management Business</td><td></td><td>241</td></tr><tr><td>Western European Business</td><td></td><td>1,537</td></tr><tr><td>Other International Business</td><td></td><td>—</td></tr><tr><td>Corporate and Other Business</td><td></td><td>2,986</td></tr><tr><td>Total</td><td>$ 10,167</td><td></td></tr></table>



In the first quarter of 2016, we implemented additional actions associated with our Transformation Initiative. As a result of these actions, we expect to record a charge of approximately $7.0 million, primarily related to employee severance and associated benefits, and included as a component of selling, general and administrative expenses. Of this charge, approximately $4.4 million, $0.7 million, $0.1 million and $1.8 million was associated with our North American Records and Information Management Business, North American Data Management Business, Western European Business and Corporate and Other Business segments, respectively.

As we quantify incremental costs associated with future Transformation Initiative actions to achieve our $125.0 million cost reduction goal, we will disclose the relevant cost estimates and charges in the period that such actions are approved.

## General

As a result of a realignment in our senior management reporting structure during the first quarter of 2015, we modified our internal financial reporting to better align internal reporting with how we manage our business. These modifications resulted in the separation of our former International Business segment into two unique reportable operating segments, which we refer to as (1) Western European Business segment and (2) Other International Business segment. Also, during the first quarter of 2015, we reassessed the nature of certain costs which were previously being allocated to the North American Records and Information Management Business and North American Data Management Business segments. As a result of this reassessment, we determined that certain product management functions, which were previously being performed to solely benefit our North American operating segments, are now being performed in a manner that benefits the enterprise as a whole. Accordingly, the costs associated with these product management functions are now included within the Corporate and Other Business segment. Additionally, during the fourth quarter of 2015, as a result of changes in the senior management of our business in Norway, we determined that our Norway operations are now being managed as a component of our Other International Business segment rather than as a component of our Western European Business segment.

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

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 technology escrow services that protect and manage source code ("Intellectual Property Management"). 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 DMS, 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 and detailed reporting of customer marketing literature and delivery to sales offices, trade shows and prospective customers' sites based on current and prospective customer orders ("Fulfillment Services"); (9) consulting services; and (10) other technology services and product sales (including specially designed storage containers and related supplies). Our service revenue growth has been negatively impacted by declining activity rates as stored records are becoming less active. While customers continue to store their records with us, they are less likely than they have been in the past to retrieve records for research purposes, thereby reducing service activity levels.

Cost of sales (excluding depreciation and amortization) consists primarily of wages and benefits for field personnel, facility occupancy costs (including rent and utilities), transportation expenses (including vehicle leases and fuel), other product cost of sales and other equipment costs and supplies. Of these, wages and benefits and facility occupancy costs are the most significant. Selling, general and administrative expenses consist primarily of wages and benefits for management, administrative, information technology, sales, account management and marketing personnel, as well as expenses related to communications and data processing, travel, professional fees, bad debts, training, office equipment and supplies. Trends in facility occupancy costs are impacted by the total number of facilities we occupy, the mix of properties we own versus properties we occupy under operating leases, fluctuations in per square foot occupancy costs, and the levels of utilization of these properties. Trends in total wages and benefits in dollars and as a percentage of total consolidated revenue are influenced by changes in headcount and compensation levels, achievement of incentive compensation targets, workforce productivity and variability in costs associated with medical insurance and workers' compensation.

The expansion of our international businesses has impacted the major cost of sales components and selling, general and administrative expenses. Our international operations are more labor intensive than our operations in North America and, therefore, labor costs are a higher percentage of international segment revenue. In addition, the overhead structure of our



expanding international operations has not achieved the same level of overhead leverage as our North American segments, which may result in an increase in selling, general and administrative expenses, as a percentage of consolidated revenue, as our international operations become a more meaningful percentage of our consolidated results.

Our depreciation and amortization charges result primarily from the capital-intensive nature of our business. The principal components of depreciation relate to storage systems, which include racking structures, building and leasehold improvements, computer systems hardware and software and buildings. Amortization relates primarily to customer relationship acquisition costs and is impacted by the nature and timing of acquisitions.

Our consolidated revenues and expenses are subject to variations caused by the net effect of foreign currency translation on revenues and expenses incurred by our entities outside the United States. It is difficult to predict the future fluctuations of foreign currency exchange rates and how those fluctuations will impact our Consolidated Statement 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 2013 results at the 2014 average exchange rates and the 2014 results at the 2015 average exchange rates.

The following table is a comparison of underlying average exchange rates of the foreign currencies that had the most significant impact on our United States dollar-reported revenues and expenses:

## Non-GAAP Measures

## Adjusted OIBDA

Adjusted OIBDA is defined as operating income before depreciation, amortization, intangible impairments, (gain) loss on disposal/write-down of property, plant and equipment (excluding real estate), net, Recall Costs (as defined below) and REIT Costs (as defined below). Adjusted OIBDA Margin is calculated by dividing Adjusted OIBDA by total revenues. We use multiples of current or projected Adjusted OIBDA in conjunction with our discounted cash flow models to determine our estimated overall enterprise valuation and to evaluate acquisition targets. We believe Adjusted OIBDA and Adjusted OIBDA Margin provide our current and potential investors with relevant and useful information regarding our ability to generate cash flow to support business investment. These measures are an integral part of the internal reporting system we use to assess and evaluate the operating performance of our business. Adjusted OIBDA does not include certain items that we believe are not indicative of our core operating results, specifically: (1) (gain) loss on disposal/write-down of property, plant and equipment (excluding real estate), net; (2) gain on sale of real estate, net of tax; (3) intangible impairments; (4) Recall Costs (as defined below); (5) REIT Costs (as defined below); (6) other expense (income), net; (7) income (loss) from discontinued operations, net of tax; (8) gain (loss) on sale of discontinued operations, net of tax; and (9) net income (loss) attributable to noncontrolling interests.

Adjusted OIBDA also does not include 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 OIBDA 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 OIBDA and Adjusted OIBDA Margin should be considered in addition to, but not as a substitute for, other measures of financial performance reported in accordance with accounting principles generally accepted in the United States of America ("GAAP"), such as operating or net income (loss) or cash flows from operating activities from continuing operations (as determined in accordance with GAAP).

(1) Includes operating expenditures associated with our proposed acquisition of Recall, including costs to complete the Recall Transaction, including advisory and professional fees, as well as costs incurred to integrate Recall with our existing operations, including moving, severance, facility upgrade, REIT conversion and system upgrade costs ("Recall Costs").

(2) Includes costs associated with our 2011 proxy contest, costs associated with our conversion to a REIT, excluding REIT compliance costs beginning January 1, 2014 which we expect to recur in future periods ("REIT Costs").

## Adjusted EPS

Adjusted EPS is defined as reported earnings per share from continuing operations excluding: (1) (gain) loss on disposal/write-down of property, plant and equipment (excluding real estate), net; (2) gain on sale of real estate, net of tax; (3) intangible impairments; (4) Recall Costs; (5) REIT Costs; (6) other expense (income), net; and (7) the tax impact of reconciling items and discrete tax items. We do not believe these excluded items to be indicative of our ongoing operating results, and they are not considered when we are forecasting our future results. We believe Adjusted EPS is of value to our current and potential investors when comparing our results from past, present and future periods.

(1) Adjusted EPS for the years ended December 31, 2011, 2012 and 2013 have been restated to reflect a structural tax rate of approximately 15.0%. Adjusted EPS for the year ended December 31, 2014 reflects a structural tax rate of approximately 14.4%. Adjusted EPS for the year ended December 31, 2015 reflects a structural tax rate of approximately 16.8%. The structural tax rates reflect the tax impact of the reconciling items above as well as discrete tax items.



Funds from operations (“FFO”) is defined by the National Association of Real Estate Investment Trusts ("NAREIT") and us as net income excluding (i) depreciation on real estate assets and (ii) gain on sale of real estate, net of tax (“FFO (NAREIT)”). FFO (NAREIT) does not give effect to real estate depreciation because these amounts are computed, under GAAP, to allocate the cost of a property over its useful life. Because values for well-maintained real estate assets have historically increased or decreased based upon prevailing market conditions, we believe that FFO (NAREIT) provides investors with a clearer view of our operating performance. Our most directly comparable GAAP measure to FFO (NAREIT) is net income. Although NAREIT has published a definition of FFO, modifications to FFO (NAREIT) are common among REITs as companies seek to provide financial measures that most meaningfully reflect their particular business. Our definition of FFO (Normalized) excludes certain items included in FFO (NAREIT) that we believe are not indicative of our core operating results, specifically: (1) (gain) loss on disposal/write-down of property, plant and equipment (excluding real estate), net; (2) intangible impairments; (3) Recall Costs; (4) REIT Costs; (5) other expense (income), net; (6) deferred income taxes and REIT tax adjustments; (7) income (loss) from discontinued operations, net of tax; and (8) gain (loss) on sale of discontinued operations, net of tax.

## Critical Accounting Policies

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



## Revenue Recognition

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

## Accounting for Acquisitions

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

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 estimated 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 intangible assets), property, plant and equipment (primarily racking structures), operating leases, contingencies and income taxes (primarily deferred income taxes). We complete these assessments within one year of the date of acquisition, as we acquire additional information impacting our estimates as of the acquisition date. See Note 6 to Notes to Consolidated Financial Statements included in this Annual Report for a description of recent acquisitions.

Determining the fair values of the net assets acquired requires management's judgment and often involves the use of assumptions with respect to future cash inflows and outflows, discount rates and market data, among other items. Due to the inherent uncertainty of future events, actual values of net assets acquired could be different from our estimated fair values and could have a material impact on our financial statements.

Of the net assets acquired in our acquisitions, the fair value of owned buildings, customer relationship 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 party appraisals of the fair value of owned buildings, customer relationship 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 party appraisals of fair value for acquired owned buildings and market rental rates for acquired operating leases. When not using third party appraisals of the fair value of acquired net assets, the fair value of acquired customer relationship intangible assets and acquired racking structures is determined internally. The fair value of acquired racking structures is determined internally by taking current 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 intangible assets, which requires a significant amount of judgment by management, including estimating expected lives of the relationships, expected future cash flows and discount rates.

Of the key assumptions that impact the estimated fair values of customer relationship intangible assets, the expected future cash flows and discount rate are among the most sensitive and are considered to be critical assumptions. To illustrate the sensitivity of changes in key assumptions used in determining the fair value of customer relationship intangible assets acquired in our most significant acquisition in fiscal year 2015 (Crozier), a hypothetical increase of 10% in the expected annual future cash flows attributable to this acquisition, with all other assumptions unchanged, would have increased the calculated fair value of the acquired customer relationship intangible assets for this acquisition by $1.6 million (or 10.0%), with an offsetting decrease to goodwill. A hypothetical decrease of 100 basis points in the discount rate, with all other assumptions unchanged, would have increased the fair value of the acquired customer relationship intangible asset for this acquisition by $0.8 million (or 5.1%), with an offsetting decrease to goodwill.

Our estimates of fair value are based upon assumptions believed to be reasonable at that time but which are inherently uncertain and unpredictable. Assumptions may be incomplete or inaccurate, and unanticipated events and circumstances may occur, which may affect the accuracy of such assumptions.



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

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

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

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

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

- A current-period operating or cash flow loss combined with a history of operating or cash flow losses or a projection or forecast that demonstrates continuing losses associated with the use of a long-lived asset; and

- A current expectation that, more likely than not, an asset will be sold or otherwise disposed of significantly before the end of its previously estimated useful life.

If events indicate the carrying value of such assets may not be recoverable, recoverability of these assets is determined by comparing the forecasted undiscounted net cash flows of the operation to which the assets relate to their carrying amount. The operations are generally distinguished by the business segment and geographic region in which they operate. If the operation is determined to be unable to recover the carrying amount of its 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 intangible assets not subject to amortization: Goodwill and intangible assets with indefinite lives are not amortized but are reviewed annually for impairment or more frequently if impairment indicators arise. Other than goodwill, we currently have no intangible assets that have indefinite lives and which are not amortized.

We have selected October 1 as our annual goodwill impairment analysis date. We performed our annual goodwill impairment analysis as of October 1, 2013, 2014 and 2015 and concluded that goodwill was not impaired as of those dates. Our reporting units, at which level we performed our goodwill impairment analysis as of October 1, 2015, were as follows: (1) North American Records and Information Management (which includes Intellectual Property Management and Fulfillment Services); (2) North American Secure Shredding; (3) North American Data Management; (4) Adjacent Businesses - Data Centers (which consists primarily of our data center business in the United States); (5) Adjacent Businesses - Consumer Storage (which consists of a consumer storage business with operations in the United States acquired in April 2015); (6) the United Kingdom, Ireland and Norway (the "UKI and Norway" reporting unit); (7) Austria, Belgium, France, Germany, Netherlands, Spain and Switzerland (the "Continental Western Europe" reporting unit); (8) the remaining countries in Europe in which we operate, excluding Russia, Ukraine and Denmark (the "Emerging Markets - Eastern Europe" reporting unit); (9) Latin America; (10) Australia and Singapore; (11) China and Hong Kong (the "Greater China" reporting unit); (12) India; and (13) Russia, Ukraine and Denmark. See Note 2.g. to Notes to Consolidated Financial Statements included in our Annual Report for a description of our reporting units.

Based on our goodwill impairment analysis as of October 1, 2015, all of our reporting units with goodwill had estimated fair values that exceeded their carrying values by greater than 25%. As of December 31, 2015, no factors were identified that would alter our October 1, 2015 goodwill impairment analysis. In making this assessment, we relied on 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. When changes occur in the composition of one or more reporting units, the goodwill is reassigned to the reporting units affected based on their relative fair values.

Reporting unit valuations have been determined using a combined approach based on the present value of future cash flows and market multiples of revenues and/or earnings. The income approach incorporates many assumptions including future growth rates, discount 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.



Although we believe we have sufficient historical and projected information available to us to test for 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, 2015. With respect to all of our reporting units as of October 1, 2015, we noted that, based on the fair value of these reporting units determined as of October 1, 2015, (i) a hypothetical decrease of 10% in the expected annual future cash flows of these reporting units, with all other assumptions unchanged, would have decreased the fair value of these reporting units as of October 1, 2015 by a range of approximately 8.3% to 10.5% but would not, however, have resulted in the carrying value of any of these reporting units with goodwill exceeding their fair value; and (ii) a hypothetical increase of 100 basis points in the discount rate, with all other assumptions unchanged, would have decreased the fair value of these reporting units as of October 1, 2015 by a range of approximately 5.1% to 21.8% but would not, however, have resulted in the carrying value of any of these reporting units with goodwill exceeding their fair value.

## Income Taxes

As a REIT, we are generally permitted to deduct from our federal taxable income the dividends we pay to our stockholders. The income represented by such dividends is not subject to federal taxation at the entity level but is taxed, if at all, at the stockholder level. The income of our domestic TRSs, which hold our domestic operations that may not be REIT-compliant as currently operated and structured, is subject, as applicable, to federal and state corporate income tax. In addition, we and our subsidiaries continue to be subject to foreign income taxes in jurisdictions in which we have business operations or a taxable presence, regardless of whether assets are held or operations are conducted through subsidiaries disregarded for federal tax purposes or TRSs. We will also be subject to a separate corporate income tax on any gains recognized during a five-year period following the REIT conversion that are attributable to "built-in" gains with respect to the assets that we owned on January 1, 2014. This built-in gains tax has been imposed on our depreciation recapture recognized into income as a result of accounting method changes commenced in our pre-REIT period. If we fail to remain qualified for taxation as a REIT, we will be subject to federal income tax at regular corporate tax rates. As a REIT, we may be subject to some federal, state, local and foreign taxes on our income and property in addition to taxes owed with respect to our TRS operations. In particular, while state income tax regimes often parallel the federal income tax regime for REITs, many states do not completely follow federal rules and some do not follow them at all.

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

We have federal net operating loss carryforwards, which expire in 2021 through 2033, of $70.8 million at December 31, 2015 to reduce future federal taxable income, on which $3.0 million of federal tax benefit is expected to be realized. We can carry forward these net operating losses to the extent we do not utilize them in any given available year. We have state net operating loss carryforwards, which expire from 2016 through 2034, on which an insignificant state tax benefit is expected to be realized. We have assets for foreign net operating losses of $66.2 million, with various expiration dates (and in some cases no expiration date), subject to a valuation allowance of approximately 91%. 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 at 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, 2014 and 2015, we had approximately $56.0 million and $47.7 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.

We had not previously provided incremental federal and certain state income taxes on net tax over book outside basis differences related to the earnings of our foreign subsidiaries because our intent, prior to our conversion to a REIT, was to reinvest our current and future undistributed earnings of certain foreign subsidiaries indefinitely outside the United States. As a result of our conversion to a REIT, it is no longer our intent to indefinitely reinvest our current and future undistributed foreign earnings outside the United States, and, therefore, during 2014, we recognized an increase in our tax provision from continuing operations in the amount of $46.4 million, representing incremental federal and state income taxes and foreign withholding taxes on such foreign earnings. We continue to provide incremental federal and state income taxes on net book over outside basis differences related to the earnings of our foreign subsidiaries. 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.

(1) Constant currency growth rates are calculated by translating the 2014 results at the 2015 average exchange rates and the 2013 results at the 2014 average exchange rates.

(2) Our revenue internal growth rate represents the weighted average year-over-year growth rate of our revenues after removing the effects of acquisitions, divestitures and foreign currency exchange rate fluctuations. We calculate revenue internal growth in local currency for our international operations.

Consolidated storage rental revenues decreased $22.3 million, or 1.2%, to $1,837.9 million for the year ended December 31, 2015 from $1,860.2 million for the year ended December 31, 2014. In the year ended December 31, 2015, consolidated storage rental internal growth and the net impact of acquisitions/divestitures were offset by unfavorable fluctuations in foreign exchange rates compared to the year ended December 31, 2014. Foreign currency exchange rate fluctuations decreased our reported storage rental revenue growth rate for the year ended December 31, 2015 by 5.2%, compared to the same prior year period. This decrease was partially offset by storage rental revenue internal growth of 2.7% in the year ended December 31, 2015, as well as the net impact of acquisitions/divestitures of 1.3% in the year ended December 31, 2015 compared to the year ended December 31, 2014. Our consolidated storage rental revenue growth in 2015 was driven by sustained storage rental internal growth of 0.1%, 4.2%, 2.7% and 10.8% in our North American Records and Information Management Business, North American Data Management Business, Western European Business and Other International Business segments, respectively. Global records management net volumes at December 31, 2015 increased by 2.3% over the ending volume at December 31, 2014, supported by 6.1% volume increases in our Other International Business segment. Consolidated storage rental revenues increased $75.5 million, or 4.2%, to $1,860.2 million for the year ended December 31, 2014 from $1,784.7 million for the year ended December 31, 2013. The reported revenue growth rate for the year ended December 31, 2014 consists primarily of revenue internal growth of 2.2%. Net acquisitions/divestitures contributed 3.2% of the increase in reported storage rental revenues in 2014 over 2013. Foreign currency exchange rate fluctuations decreased our reported storage rental revenue growth rate for the year ended December 31, 2014 by approximately 1.2%. Our consolidated storage rental revenue internal growth in 2014 was driven by sustained storage rental internal growth of 0.3%, 2.3%, 1.9% and 11.6% in our North American Records and Information Management Business, North American Data Management Business, Western European Business and Other International Business segments, respectively.



Consolidated service revenues decreased $87.4 million, or 6.9%, to $1,170.1 million for the year ended December 31, 2015 from $1,257.5 million for the year ended December 31, 2014. Service revenue internal growth was negative 0.4% for the year ended December 31, 2015, compared to the same prior year period. The negative service revenue internal growth for the year ended December 31, 2015 reflects reduced retrieval/re-file activity and a related decrease in transportation revenues within our North American Records and Information Management Business segment, 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, the decline in service activities has begun to stabilize in recent periods, while service revenue declines in the North American Data Management Business segment are reflecting more recent reductions in service activity levels. Foreign currency exchange rate fluctuations decreased our reported total service revenues by 6.0% in 2015 over 2014. Net acquisitions/divestitures decreased reported service revenues by 0.5% for the year ended December 31, 2015 compared to the year ended December 31, 2014, primarily due to a $23.7 million reduction in consolidated service revenue associated with the disposition of our International Shredding Operations. Consolidated service revenues increased $17.5 million, or 1.4%, to $1,257.5 million for the year ended December 31, 2014 from $1,239.9 million for the year ended December 31, 2013. In the year ended December 31, 2014, the net impact of acquisitions/divestitures was offset by negative service revenue internal growth and unfavorable fluctuations in foreign currency exchange rates. Net acquisitions/divestitures contributed 3.5% of the increase in reported service revenues in 2014. Service revenue internal growth was negative 0.7% for the year ended December 31, 2014. The negative service revenue internal growth for 2014 reflects reduced retrieval/re-file activity and a related decrease in transportation revenues within our North American Records and Information Management Business segment, 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. Foreign currency exchange rate fluctuations decreased reported service revenues by 1.4% in 2014 over 2013.

For the reasons stated above, our consolidated revenues decreased $109.7 million, or 3.5%, to $3,008.0 million for the year ended December 31, 2015 from $3,117.7 million for the year ended December 31, 2014. For the year ended December 31, 2015, foreign currency exchange rate fluctuations decreased our reported consolidated revenues by 5.6%, compared to the same 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. This decrease was partially offset by consolidated revenue internal growth of 1.5% in the year ended December 31, 2015 as well as the net impact of acquisitions/divestitures of 0.6% in the year ended December 31, 2015 compared to the year ended December 31, 2014. Our consolidated revenues increased $93.1 million, or 3.1%, to $3,117.7 million for the year ended December 31, 2014 from $3,024.6 million for the year ended December 31, 2013. Revenue internal growth was 1.0% for 2014. For the year ended December 31, 2014, foreign currency exchange rate fluctuations decreased our reported consolidated revenues by 1.2% primarily due to the weakening of the Australian dollar, Brazilian real and Canadian dollar, partially offset by a strengthening of the British pound sterling and the Euro against the United States dollar, based on an analysis of weighted average rates for the comparable periods. Net acquisitions/divestitures contributed an increase of 3.3% of total reported revenues in 2014 over the same period in 2013.



<table><tr><td rowspan="2"></td><td colspan="4">2014</td><td colspan="4">2015</td></tr><tr><td>First Quarter</td><td>Second Quarter</td><td>Third Quarter</td><td>Fourth Quarter</td><td>First Quarter</td><td>Second Quarter</td><td>Third Quarter</td><td>Fourth Quarter</td></tr><tr><td>Storage Rental Revenue</td><td>1.4 %</td><td>1.6 %</td><td>2.2 %</td><td>3.5%</td><td>3.0 %</td><td>2.7%</td><td>2.8 %</td><td>2.2%</td></tr><tr><td>Service Revenue</td><td>(0.7)%</td><td>(1.9)%</td><td>(2.7)%</td><td>2.3%</td><td>(1.0)%</td><td>—%</td><td>(0.9)%</td><td>0.3%</td></tr><tr><td>Total Revenue</td><td>0.5 %</td><td>0.1 %</td><td>0.2 %</td><td>3.0%</td><td>1.4 %</td><td>1.6%</td><td>1.3 %</td><td>1.4%</td></tr></table>

We expect our consolidated revenue internal growth rate for 2016 to be approximately 1.5% to 2.5%. During the past eight quarters our storage rental revenue internal growth rate has ranged between 1.4% and 3.5%. Storage rental revenue internal growth rates have been relatively stable over the past two fiscal years, averaging between 2.2% and 2.7% for full-year 2014 and 2015. At various points in the economic cycle, storage rental revenue internal growth may be influenced by changes in pricing and volume. In 2014, we initiated sales force programs focused on increasing volume through new sales and improved customer retention. In addition, we continue to enhance our pricing strategy through implementing a statistical-based approach, which enables customized pricing based on customer profiles and needs. Within our international portfolio, the Western European Business segment is generating consistent low-to-mid single-digit storage rental revenue internal growth, while the Other International Business segment is producing strong double-digit storage rental revenue internal 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 storage rental revenue internal growth rate 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 reflects reduced retrieval/re-file activity and a related decrease in transportation revenues within our North American Records and Information Management Business segment, as well as continued service declines in service revenue activity levels in our North American Data Management Business segment as the storage business becomes more archival in nature.

## Labor

Labor expense decreased to 21.5% of consolidated revenues for the year ended December 31, 2015 compared to 21.6% for the year ended December 31, 2014. Labor costs were favorably impacted by 6.9 percentage points due to currency rate changes during the year ended December 31, 2015 compared to the same prior year period. Labor expense for the year ended December 31, 2015 increased by 2.8% on a constant dollar basis compared to the year ended December 31, 2014. This increase was primarily due to a $14.6 million increase in labor costs in our Other International Business segment, primarily associated with the impact of recent acquisitions, and a $7.0 million increase in labor costs in our North American Records and Information Management Business segment, primarily associated with an increase in medical expenses. These increases were partially offset by a $1.2 million reduction in restructuring costs associated with the Organizational Restructuring (primarily related to our North American Records and Information Management Business segment) in the year ended December 31, 2015 compared to the year ended December 31, 2014.

Labor expense increased to 21.6% of consolidated revenues for the year ended December 31, 2014 compared to 21.1% for the year ended December 31, 2013. Labor expense for the year ended December 31, 2014 increased by 7.7% on a constant dollar basis compared to the year ended December 31, 2013, primarily due to incremental labor costs associated with acquisitions completed during fiscal year 2014 and the fourth quarter of 2013, as well as merit increases, partially offset by a $2.2 million decrease in restructuring costs. Labor costs were favorably impacted by 2.0 percentage points due to currency rate changes during the year ended December 31, 2014.



## Facilities

We recorded net foreign currency transaction losses of $70.9 million in the year ended December 31, 2015, based on period-end exchange rates. These losses resulted primarily from changes in the exchange rate of each of the Argentine peso, Brazilian real, Euro, Russian ruble and Ukrainian hryvnia against the United States dollar compared to December 31, 2014, as these currencies relate to our intercompany balances with and between our Latin American and European subsidiaries, as well as Euro forward contracts.

These losses were partially offset by gains primarily from British pound sterling borrowings on our revolving credit facility, Australian dollar and British pound sterling forward contracts, and Euro denominated bonds issued by IMI.

We recorded net foreign currency transaction losses of $36.2 million in the year ended December 31, 2013, based on period-end exchange rates. These losses resulted primarily from changes in the exchange rate of each of the Australian dollar, Brazilian real, Russian ruble and Euro against the United States dollar compared to December 31, 2012, as these currencies relate to our intercompany balances with and between our European, Australian and Brazilian subsidiaries as well as British pound sterling debt and forward currency contracts, which were partially offset by gains as a result of an Australian forward currency contract, as well as changes in the exchange rate of the British pound sterling against the United States dollar compared to December 31, 2012 as it relates to our intercompany balances with and between our United Kingdom subsidiaries.

During the year ended December 31, 2015, we recorded a debt extinguishment charge of $27.3 million related to (i) the refinancing of the Credit Agreement in the third quarter of 2015 and (ii) the early extinguishment of the 6 \( ^{3} \) /4% Notes, 7 \( ^{3} \) /4% Notes and the remaining portion outstanding of the 8 \( ^{3} \) /8% Notes in the fourth quarter of 2015.

During the year ended December 31, 2014, we recorded a debt extinguishment charge of $16.5 million related to the early redemption of $306.0 million in aggregate principal of the 8 \( ^{3} \) /8% Notes at 104.188% of par. This charge consists of call premiums, original issue discounts and unamortized deferred financing costs. During the year ended December 31, 2013, we recorded a debt extinguishment charge of $43.7 million related to (i) the amendment of our Former Credit Agreement (as defined below) in the third quarter of 2013, representing a write-off of deferred financing costs, and (ii) the early extinguishment of the 7 \( ^{1} \) /2% Notes, the 8% Notes due 2018, the 8% Notes due 2020 and a portion of the 8 \( ^{3} \) /8% Notes. This charge consists of call premiums, original issue discounts and unamortized deferred financing costs.

Other, net in the year ended December 31, 2015 consisted primarily of $0.6 million related to the write-down of certain investments. Other, net in the year ended December 31, 2014 included income of $9.6 million. In December 2014, we divested our secure shredding operations in Australia, Ireland and the United Kingdom in a stock transaction and recorded a pretax gain of approximately $6.9 million (see Note 16 to Notes to Consolidated Financial Statements included in this Annual Report). Also included in other, net in the year ended December 31, 2014 was approximately $0.9 million of royalty income and $1.1 million of gains associated with a deferred compensation plan we sponsor. Other, net in the year ended December 31, 2013 consists primarily of $3.7 million of royalty income.

## Provision for Income Taxes

Our effective tax rates for the years ended December 31, 2013, 2014 and 2015 were 38.9%, (43.5%) and 23.3%, respectively. The primary reconciling items between the federal statutory rate of 35% and our overall effective tax rate for the year ended December 31, 2013 were the impact from the repatriation discussed below, which increased our 2013 effective tax rate by 13.1%, and state income taxes (net of federal tax benefit). These expenses were partially offset by a favorable impact provided by the recognition of certain previously unrecognized tax benefits due to expirations of statute of limitation periods and settlements with tax authorities in various jurisdictions and differences in the rates of tax at which our foreign earnings are subject, including foreign exchange gains and losses in different jurisdictions with different tax rates.

During 2013, we completed a plan to utilize both current and carryforward foreign tax credits by repatriating approximately $252.7 million (approximately $65.2 million of which was previously subject to United States taxes) from our foreign earnings. Due to uncertainty in our ability to fully utilize foreign tax credit carryforwards, we previously did not recognize a full benefit for such foreign tax credit carryforwards in our tax provision. As a result, we recorded an increase in our tax provision from continuing operations in the amount of $63.5 million in 2013. This increase was offset by decreases of $18.8 million from current year foreign tax credits and $23.3 million reversal of valuation allowances related to foreign tax credit carryforwards, resulting in a net increase of $21.5 million in our tax provision from continuing operations.



As a result of our REIT conversion, we recorded a net tax benefit of $212.2 million during the year ended December 31, 2014 for the revaluation of certain deferred tax assets and liabilities associated with the REIT conversion. In 2014, we recorded an increase to the tax provision of $29.3 million associated with tax accounting method changes consistent with our REIT conversion, primarily affected through the filing of amended tax returns. The other primary reconciling items between the federal statutory rate of 35% and our overall effective tax rate during the year ended December 31, 2014 was an increase of $46.4 million in our tax provision associated with incremental federal and state income taxes and foreign withholding taxes on earnings of our foreign subsidiaries no longer considered permanently invested and other net tax adjustments related to the REIT conversion, including a tax benefit of $63.3 million primarily related to the dividends paid deduction.

The primary reconciling items between the federal statutory rate of 35% and our overall effective tax rate for the year ended December 31, 2015 were the benefit derived from the dividends paid deduction of $51.6 million and an out-of-period tax adjustment (approximately $9.0 million tax benefit) recorded during the third quarter to correct the valuation of certain deferred tax assets associated with the REIT conversion that occurred in 2014, partially offset by valuation allowances on certain of our foreign net operating losses of $33.5 million, primarily related to our foreign subsidiaries in Argentina, Brazil, France and Russia.

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.

Our effective tax rate is subject to variability in the future due to, among other items: (1) changes in the mix of income between our qualified REIT subsidiaries and our TRSs, as well as between 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. We are subject to income taxes in the United States and numerous foreign jurisdictions. We are subject to examination by various tax authorities in jurisdictions in which we have business operations or a taxable presence. We regularly assess the likelihood of additional assessments by tax authorities and provide for these matters as appropriate. Although we believe our tax estimates are appropriate, the final determination of tax audits and any related litigation could result in changes in our estimates.

## Gain on Sale of Real Estate, Net of Tax

Consolidated gain on sale of real estate for the year ended December 31, 2015 was $0.9 million, net of tax of $0.2 million associated with the sale of a building in the United Kingdom.

## INCOME (LOSS) FROM DISCONTINUED OPERATIONS

Loss from discontinued operations, net of tax was $0.2 million for the year ended December 31, 2014, primarily related to legal reserves, offset by the recovery of insurance proceeds in excess of carrying value. Income from discontinued operations, net of tax was $0.8 million for the year ended December 31, 2013, which primarily represents the recovery of insurance proceeds in excess of carrying value.

## NONCONTROLLING INTERESTS

Net income attributable to noncontrolling interests resulted in a decrease in net income attributable to Iron Mountain Incorporated of $2.0 million, $2.6 million and $3.5 million for the years ended December 31, 2015, 2014 and 2013, 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)

As a result of a realignment in our senior management reporting structure during the first quarter of 2015, we modified our internal financial reporting to better align internal reporting with how we manage our business. These modifications resulted in the separation of our former International Business segment into two unique reportable operating segments, which we refer to as (1) Western European Business segment and (2) Other International Business segment. Also, during the first quarter of 2015, we reassessed the nature of certain costs which were previously being allocated to the North American Records and Information Management Business and North American Data Management Business segments. As a result of this reassessment, we determined that certain product management functions, which were previously being performed to solely benefit our North American operating segments, are now being performed in a manner that benefits the enterprise as a whole. Accordingly, the costs associated with these product management functions are now included within the Corporate and Other Business segment. Additionally, during the fourth quarter of 2015, as a result of changes in the senior management of our business in Norway, we determined that our Norway operations are now being managed as a component of our Other International Business segment rather than as a component of our Western European Business segment.

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

Our five reportable operating segments are described as follows:

- North American Records and Information Management Business—storage and information management services, including Records Management, Destruction and DMS throughout the United States and Canada; as well as Fulfillment Services and Intellectual Property Management in the United States.

- North American Data Management Business—Data Protection & Recovery; server and computer backup services; digital content repository systems to house, distribute, and archive key media assets; and storage, safeguarding and electronic or physical delivery of physical media of all types, primarily for entertainment and media industry clients, throughout the United States and Canada.

- Western European Business—storage and information management services, including Records Management, Data Protection & Recovery and DMS throughout the United Kingdom, Ireland, Austria, Belgium, France, Germany, Netherlands, Spain and Switzerland. Until December 2014, our Western European Business segment offered Destruction in the United Kingdom and Ireland.

- Other International Business—storage and information management services throughout the remaining European countries in which we operate, Latin America and Asia Pacific, including Records Management, Data Protection & Recovery and DMS. Our European operations included within the Other International Business segment provide Records Management, Data Protection & Recovery and DMS. Our Latin America operations provide Records Management, Data Protection & Recovery, Destruction and DMS throughout Argentina, Brazil, Chile, Colombia, Mexico and Peru. Our Asia Pacific operations provide Records Management, Data Protection & Recovery and DMS throughout Australia, with Records Management and Data Protection & Recovery also provided in certain cities in India, Singapore, Hong Kong-SAR and China. Until December 2014, our Other International Business segment offered Destruction in Australia.

- Corporate and Other Business—primarily consists of our data center and fine art storage businesses in the United States, the primary product offerings of our Adjacent Businesses operating segment (which was formerly referred to as our Emerging Businesses operating segment), as well as costs related to executive and staff functions, including finance, human resources and information technology, which benefit the enterprise as a whole. These costs are primarily related to the general management of these functions on a corporate level and the design and development of programs, policies and procedures that are then implemented in the individual segments, with each segment bearing its own cost of implementation. Our Corporate and Other Business segment also includes stock-based employee compensation expense associated with all stock options, restricted stock, restricted stock units, performance units and shares of stock issued under our employee stock purchase plan.

For the year ended December 31, 2015, reported revenue in our North American Records and Information Management Business segment decreased 1.1% compared to the year ended December 31, 2014, primarily due to negative internal growth and foreign currency exchange rate fluctuations. For the year ended December 31, 2015, foreign currency exchange rate fluctuations decreased our reported revenues for the North American Records and Information Management Business segment by 1.5% compared to the same prior year period due to the weakening of the Canadian dollar against the United States dollar. Negative internal growth of 0.6% in the year ended December 31, 2015 was primarily the result of negative service revenue internal growth of 1.6% in the year ended December 31, 2015, resulting from reduced retrieval/re-file activity and a related decrease in transportation revenues. Net acquisitions/divestitures increased reported revenue in our North American Records and Information Management Business segment by 1.0% in the year ended December 31, 2015, compared to the year ended December 31, 2014. Adjusted OIBDA as a percentage of segment revenue increased 140 basis points during the year ended December 31, 2015 compared to the year ended December 31, 2014, primarily driven by a $11.7 million decrease in professional fees, a $7.5 million decrease in fuel and insurance costs, a $5.7 million decrease in incentive compensation and a $1.6 million decrease in costs due to the Organizational Restructuring, as well as a decrease in sales, marketing and account management costs. These decreases were partially offset by $5.4 million of employee severance costs recorded during the year ended December 31, 2015 associated with the Transformation Initiative.

For the year ended December 31, 2014, reported revenue in our North American Records and Information Management Business segment increased 1.5% compared to the year ended December 31, 2013. This increase is primarily attributable to the impact of acquisitions of 2.3% in the year ended December 31, 2014 compared to the year ended December 31, 2013. Flat total internal growth was primarily the result of negative service internal growth of 0.5%, resulting from a trend toward reduced retrieval/re-file activity and a related decrease in transportation revenues, partially offset by storage rental revenue internal growth of 0.3% in the year ended December 31, 2014, primarily related to net price increases. For the year ended December 31, 2014, foreign currency exchange rate fluctuations decreased our reported revenues for the North American Records and Information Management Business segment by 0.8% compared to the year ended December 31, 2013 due to the weakening of the Canadian dollar against the United States dollar. Adjusted OIBDA as a percentage of segment revenue increased 200 basis points in the year ended December 31, 2014 compared to 2013, primarily due to decreases in restructuring charges and compensation expense as a result of the organizational restructuring initiated in the fourth quarter of 2013.

For the year ended December 31, 2015, reported revenue in our North American Data Management Business segment increased 0.1% compared to the year ended December 31, 2014, primarily due to internal growth of 0.8%. The internal growth was primarily attributable to storage rental revenue internal growth of 4.2%, partially offset by negative service revenue internal growth of 5.1% in the year ended December 31, 2015, which was due to declines in service revenue activity levels as the storage business becomes more archival in nature. For the year ended December 31, 2015, foreign currency exchange rate fluctuations decreased our reported revenues for the North American Data Management Business segment by 0.9% compared to the prior year due to the weakening of the Canadian dollar against the United States dollar. Adjusted OIBDA as a percentage of segment revenue decreased 580 basis points in the year ended December 31, 2015 compared to the year ended December 31, 2014, primarily due to increased overhead expenses of $15.9 million, primarily associated with higher sales, marketing and account management expenses and, to a lesser extent, reduced gross profit related to a decline in service revenues without a corresponding decrease in costs.

For the year ended December 31, 2014, reported revenue in our North American Data Management Business segment decreased 1.6% compared to the year ended December 31, 2013, primarily due to negative internal growth of 1.5%. The negative internal growth was primarily attributable to negative service internal growth of 7.5%, which was due to declines in service revenue activity levels as the storage business becomes more archival in nature, partially offset by storage rental revenue internal growth of 2.3% in the year ended December 31, 2014, primarily related to net price increases. For the year ended December 31, 2014, foreign currency exchange rate fluctuations decreased our reported revenues for the North American Data Management Business segment by 0.5% compared to the year ended December 31, 2013 due to the weakening of the Canadian dollar against the United States dollar. Adjusted OIBDA as a percentage of segment revenue declined 190 basis points in the year ended December 31, 2014 compared to the year ended December 31, 2013, primarily due to the aforementioned negative internal growth, as well as costs not decreasing in proportion to the decline in revenue.

For the year ended December 31, 2015, reported revenue in our Western European Business segment decreased 11.5% compared to the year ended December 31, 2014, primarily as a result of fluctuations in foreign currency exchange rates. Foreign currency fluctuations resulted in decreased revenue in the year ended December 31, 2015, as measured in United States dollars, of approximately 10.4% as compared to the same prior year period, due to the weakening of the British pound sterling and the Euro against the United States dollar. Revenue internal growth for the year ended December 31, 2015 was 1.4%, supported by 2.7% storage rental revenue internal growth for the year ended December 31, 2015. Net acquisitions/divestitures decreased reported revenue in our Western European Business segment by 2.5% in the year ended December 31, 2015, compared to the year ended December 31, 2014, primarily due to a $15.3 million reduction in reported service revenues associated with the disposition of our shredding operations in the United Kingdom and Ireland in December 2014. Adjusted OIBDA as a percentage of segment revenue increased 140 basis points during the year ended December 31, 2015 compared to the year ended December 31, 2014, primarily due to improved profitability associated with lower transportation and facility costs.

For the year ended December 31, 2014, reported revenues in our Western European Business segment increased 3.2% compared to the year ended December 31, 2013. Internal growth for the year ended December 31, 2014 was negative 0.6%, driven by negative 4.0% service revenue internal growth, partially offset by storage rental revenue internal growth of 1.9%. Foreign currency fluctuations in 2014 resulted in increased revenue for the year ended December 31, 2014, as measured in United States dollars, of approximately 3.4% as compared to the year ended December 31, 2013, due to the strengthening of the British pound sterling and the Euro against the United States dollar. Net acquisitions/divestitures increased total reported revenue growth in the year ended December 31, 2014 by 0.4%. Adjusted OIBDA as a percentage of segment revenue increased by 170 basis points in the year ended December 31, 2014 compared to the year ended December 31, 2013, primarily due to improved profitability as a result of real estate optimization in the United Kingdom during 2013 and early 2014.

For the year ended December 31, 2015, reported revenues in our Other International Business segment decreased 10.2% compared to the year ended December 31, 2014, primarily as a result of fluctuations in foreign currency exchange rates. Foreign currency fluctuations in the year ended December 31, 2015 resulted in decreased revenue, as measured in United States dollars, of approximately 21.7% as compared to the same prior year period, primarily due to the weakening of the Australian dollar, Brazilian real and Euro against the United States dollar. Revenue internal growth for the year ended December 31, 2015 was 10.0% supported by 10.8% storage rental revenue internal growth for the year ended December 31, 2015. Net acquisitions/divestitures increased reported revenue in our Other International Business segment by 1.5% in the year ended December 31, 2015 compared to the year ended December 31, 2014, as the impact of our recent acquisitions in Brazil, Turkey and Poland were partially offset by a $8.4 million decrease in reported service revenues for the year ended December 31, 2015 associated with the disposition of our Australian shredding operations in December 2014. Adjusted OIBDA as a percentage of segment revenue increased 270 basis points during the year ended December 31, 2015 compared to the year ended December 31, 2014. The increase in Adjusted OIBDA as a percentage of segment revenue during the year ended December 31, 2015 was primarily a result of a constant dollar increase in gross profit of 11.0% in the year ended December 31, 2015 compared to the same prior year period. The constant dollar increase in gross profit for the year ended December 31, 2015 was partially offset by the impact of changes in foreign currency exchange rates.

For the year ended December 31, 2014, reported revenues in our Other International Business segment increased 14.4% compared to the year ended December 31, 2013. Internal growth for the year ended December 31, 2014 was 10.7%, supported by 11.6% storage rental internal growth and 9.4% total service revenue internal growth. Net acquisitions/divestitures contributed 14.3% of the increase in total reported revenue growth in the year ended December 31, 2014. Foreign currency fluctuations in 2014 resulted in decreased revenue in the year ended December 31, 2014, as measured in United States dollars, of approximately 10.6% as compared to the year ended December 31, 2013, primarily due to the weakening of the Australian dollar and Brazilian real against the United States dollar. Adjusted OIBDA as a percentage of segment revenue decreased by 330 basis points in the year ended December 31, 2014 compared to the year ended December 31, 2013, primarily due to the impact associated with a fire at one of our facilities in Buenos Aires, Argentina in February 2014, as well as integration costs associated with recent international acquisitions.

For the year ended December 31, 2015, Adjusted OIBDA in the Corporate and Other Business segment as a percentage of consolidated revenue was flat compared to the year ended December 31, 2014. Adjusted OIBDA for the Corporate and Other Business segment increased by $7.8 million in the year ended December 31, 2015 compared to the prior year primarily due to decreased insurance costs of $3.5 million associated with a fire at one of our facilities in Buenos Aires, Argentina in February 2014, as well as a decrease in general and administrative expenses, primarily related to professional fees.

For the year ended December 31, 2014, Adjusted OIBDA in the Corporate and Other Business segment as a percentage of consolidated revenue decreased by 20 basis points compared to the year ended December 31, 2013, primarily due to increased insurance costs of $3.5 million associated with the fire at one of our facilities in Buenos Aires, Argentina noted above, higher professional fees of $2.6 million, restructuring costs of $1.5 million and REIT compliance costs.

<table><tr><td></td><td>2013</td><td>2014</td><td>2015</td></tr><tr><td>Cash flows from operating activities—continuing operations</td><td>$ 506,593</td><td>$ 472,948</td><td>$ 541,760</td></tr><tr><td>Cash flows from investing activities—continuing operations</td><td>(632,750)</td><td>(479,978)</td><td>(422,786)</td></tr><tr><td>Cash flows from financing activities—continuing operations</td><td>18,564</td><td>19,857</td><td>(108,511)</td></tr><tr><td>Cash and cash equivalents at the end of year</td><td>120,526</td><td>125,933</td><td>128,381</td></tr></table>

Net cash provided by operating activities from continuing operations was $541.8 million for the year ended December 31, 2015 compared to $472.9 million for the year ended December 31, 2014. The 14.5% year-over-year increase resulted primarily from an increase in net income (including non-cash charges and realized foreign exchange losses) of $79.2 million, partially offset by an increase in cash used in working capital of $10.4 million primarily related to the payments and timing of certain accrued expenses and deferred revenue liabilities.

Our business requires capital expenditures to maintain our ongoing operations, support our expected revenue growth and new products and services, and increase our profitability. These expenditures are included in the cash flows from investing activities. The nature of our capital expenditures has evolved over time along with the nature of our business. Our capital goes to support business-line growth and our ongoing operations, but we also expend capital to support the development and improvement of products and services and projects designed to increase our profitability. These expenditures are generally discretionary in nature. Cash paid for our capital expenditures, cash paid for acquisitions (net of cash acquired), acquisition of customer relationships and Customer Inducements during the year ended December 31, 2015 amounted to $290.2 million, $113.6 million, $32.6 million and $22.5 million, respectively. For the year ended December 31, 2015, these expenditures were primarily funded with cash flows from operations. Excluding capital expenditures associated with potential future acquisitions and opportunistic real estate investments, we expect our capital expenditures to be approximately $300.0 million to $330.0 million in the year ending December 31, 2016. We expect to spend up to $100.0 million of additional capital expenditures on opportunistic real estate investments in the year ending December 31, 2016.

Net cash used in financing activities from continuing operations was $108.5 million for the year ended December 31, 2015. During the year ended December 31, 2015, we received net proceeds of $985.0 million associated with the issuance of the 6% Notes due 2020 in September 2015, $128.8 million associated with our revolving credit and term loan facilities (including the Accounts Receivable Securitization Program) and $7.1 million from the exercise of stock options and our employee stock purchase plan. We used the proceeds from these transactions, as well as cash flows provided by operating activities, for the redemption of the 6 \( ^{3} \) /4% Notes, the 7 \( ^{3} \) /4% Notes and the 8 \( ^{3} \) /8% Notes for approximately $814.7 million (inclusive of call premiums) and payment of dividends in the amount of $406.5 million on our common stock.



## Capital Expenditures

The following table presents our capital spend for 2013, 2014 and 2015 organized by the type of the spending as described in the "Our Business Fundamentals" section of "Item 1. Business" included in this Annual Report:

## Dividends

See "Item 5. Market For Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities" of this Annual Report for information on dividends.



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, 2015 related to cash and cash equivalents held in time deposits with four global banks, all of which we consider to be large, highly-rated investment-grade institutions. As per our risk management investment policy, we limit exposure to concentration of credit risk by limiting the amount invested in any one mutual fund to a maximum of $50.0 million or in any one financial institution to a maximum of $75.0 million. As of December 31, 2015, our cash and cash equivalents balance was $128.4 million, which included time deposits amounting to $18.6 million.

Our consolidated debt as of December 31, 2015 comprised the following (in thousands):

<table><tr><td rowspan="2"></td><td colspan="3">December 31, 2015</td></tr><tr><td>Debt (inclusive of discount and premium)</td><td>Unamortized Deferred Financing Costs</td><td>Carrying Amount</td></tr><tr><td>Revolving Credit Facility(1)</td><td>$ 784,438</td><td>$ (9,410)</td><td>$ 775,028</td></tr><tr><td>Term Loan(1)</td><td>243,750</td><td>—</td><td>243,750</td></tr><tr><td>6% Notes due 2020(2)(3)</td><td>1,000,000</td><td>(16,124)</td><td>983,876</td></tr><tr><td>CAD Notes(4)</td><td>144,190</td><td>(1,924)</td><td>142,266</td></tr><tr><td>GBP Notes(3)(5)</td><td>592,140</td><td>(8,757)</td><td>583,383</td></tr><tr><td>6% Notes due 2023(2)</td><td>600,000</td><td>(8,420)</td><td>591,580</td></tr><tr><td>5 \( ^{3} \) / \( _{4} \) % Senior Subordinated Notes due 2024 (2)</td><td>1,000,000</td><td>(11,902)</td><td>988,098</td></tr><tr><td>Real Estate Mortgages, Capital Leases and Other(6)</td><td>333,559</td><td>(1,070)</td><td>332,489</td></tr><tr><td>Accounts Receivable Securitization Program(7)</td><td>205,900</td><td>(692)</td><td>205,208</td></tr><tr><td>Total Long-term Debt</td><td>4,903,977</td><td>(58,299)</td><td>4,845,678</td></tr><tr><td>Less Current Portion</td><td>(88,068)</td><td>—</td><td>(88,068)</td></tr><tr><td>Long-term Debt, Net of Current Portion</td><td>$ 4,815,909</td><td>$ (58,299)</td><td>$ 4,757,610</td></tr></table>

(1) The capital stock or other equity interests of most of our United States subsidiaries, and up to 66% of the capital stock or other equity interests of our first-tier foreign subsidiaries, are pledged to secure these debt instruments, together with all intercompany obligations (including promissory notes) of subsidiaries owed to us or to one of our United States subsidiary guarantors. In addition, Canada Company has pledged 66% of the capital stock of its subsidiaries, and all intercompany obligations (including promissory notes) owed to or held by it, to secure the Canadian dollar subfacility under the Revolving Credit Facility (as defined below).

(2) Collectively, the "Parent Notes." IMI is the direct obligor on the Parent Notes, which are fully and unconditionally guaranteed, on a senior or senior subordinated basis, as the case may be, by its direct and indirect 100% owned United States subsidiaries that represent the substantial majority of our United States operations (the "Guarantors"). These guarantees are joint and several obligations of the Guarantors. Canada Company, IME, the Special Purpose Subsidiaries (as defined below) and the remainder of our subsidiaries do not guarantee the Parent Notes. See Note 5 to Notes to Consolidated Financial Statements included in this Annual Report.

(3) The 6% Notes due 2020 and the GBP Notes have not been registered under the Securities Act of 1933, as amended (the “Securities Act”), or under the securities laws of any other jurisdiction. Unless they are registered, the 6% Notes due 2020 and the GBP Notes may be offered only in transactions that are exempt from registration under the Securities Act or the securities laws of any other jurisdiction.

(4) Canada Company is the direct obligor on the CAD Notes, which are fully and unconditionally guaranteed, on a senior basis, by IMI and the Guarantors. These guarantees are joint and several obligations of IMI and the Guarantors. See Note 5 to Notes to Consolidated Financial Statements included in this Annual Report.



(5) IME is the direct obligor on the GBP Notes, which are fully and unconditionally guaranteed, on a senior basis, by IMI and the Guarantors. These guarantees are joint and several obligations of IMI and the Guarantors. See Note 5 to Notes to Consolidated Financial Statements included in this Annual Report.

(6) Includes (a) real estate mortgages of $2.7 million, (b) capital lease obligations of $235.4 million, and (c) other various notes and other obligations, which were assumed by us as a result of certain acquisitions, of $95.5 million.

(7) The Special Purpose Subsidiaries are the obligors under this program.

On July 2, 2015, we entered into a new credit agreement (the "Credit Agreement") to refinance 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 June 27, 2016. The Credit Agreement consists of a revolving credit facility (the "Revolving Credit Facility") and a term loan (the "Term Loan").

The Revolving Credit Facility is supported by a group of 25 banks and 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, Euros and Australian dollars, among other currencies) in an aggregate outstanding amount not to exceed $1,500.0 million. The Term Loan is to be paid in quarterly installments in an amount equal to $3.1 million per quarter, with the remaining balance due on July 3, 2019. The Credit Agreement includes an option to allow us 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 as defined in the Credit Agreement. The Credit Agreement terminates on July 6, 2019, at which point all obligations become due, but may be extended by one year at our option, subject to the conditions set forth in the Credit Agreement. Borrowings under the Credit Agreement may be prepaid without penalty or premium, in whole or in part, at any time.

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, 2015, we had $784.4 million and $243.8 million of outstanding borrowings under the Revolving Credit Facility and the Term Loan, respectively. Of the $784.4 million of outstanding borrowings under the Revolving Credit Facility, $480.4 million was denominated in United States dollars, 190.0 million was denominated in Canadian dollars, 105.3 million was denominated in Euros and 71.6 million was denominated in Australian dollars. In addition, we also had various outstanding letters of credit totaling $36.6 million. The remaining amount available for borrowing under the Revolving Credit Facility as of December 31, 2015, based on IMI's leverage ratio, the last 12 months' earnings before interest, taxes, depreciation and amortization and rent expense ("EBITDAR"), other adjustments as defined in the Credit Agreement and current external debt, was $678.9 million (which amount represents the maximum availability as of such date). The average interest rate in effect under the Credit Agreement was 2.7% as of December 31, 2015. The average interest rate in effect under the Revolving Credit Facility was 2.8% and ranged from 2.3% to 4.8% as of December 31, 2015 and the interest rate in effect under the Term Loan as of December 31, 2015 was 2.5%.

The Credit Agreement, our indentures and other agreements governing our indebtedness contain certain restrictive financial and operating covenants, including covenants that restrict our ability to complete acquisitions, pay cash dividends, incur indebtedness, make investments, sell assets and take certain other corporate actions. The covenants do not contain a rating trigger. Therefore, a change in our debt rating would not trigger a default under the Credit Agreement, our indentures or other agreements governing our indebtedness. The Credit Agreement uses EBITDA-based calculations as the primary measures of financial performance, including leverage and fixed charge coverage ratios.



Our leverage and fixed charge coverage ratios under both the Former Credit Agreement and the Credit Agreement as of December 31, 2014 and 2015, respectively, and our leverage ratio under our indentures as of December 31, 2014 and 2015 are as follows:

<table><tr><td></td><td>December 31, 2014</td><td>December 31, 2015</td><td>Maximum//Minimum Allowable(1)</td></tr><tr><td>Net total lease adjusted leverage ratio</td><td>5.4</td><td>5.6</td><td>Maximum allowable of 6.5</td></tr><tr><td>Net secured debt lease adjusted leverage ratio</td><td>2.6</td><td>2.6</td><td>Maximum allowable of 4.0</td></tr><tr><td>Bond leverage ratio (not lease adjusted)</td><td>5.7</td><td>5.5</td><td>Maximum allowable of 6.5</td></tr><tr><td>Fixed charge coverage ratio</td><td>2.5</td><td>2.4</td><td>Minimum allowable of 1.5</td></tr></table>

(1) The maximum and minimum allowable ratios under the Credit Agreement are substantially similar to the Former Credit Agreement.

As noted in the table above, our maximum allowable net total lease adjusted leverage ratio under the Credit Agreement is 6.5. The Credit Agreement also contains a provision which limits, in certain circumstances, our dividends in any four consecutive fiscal quarters to 95% of Funds From Operations (as defined in the 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 limitation only is applicable when our net total lease adjusted leverage ratio exceeds 6.0.

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

In September 2015, IMI completed a private offering of $1,000.0 million in aggregate principal amount of the 6% Notes due 2020. The net proceeds to IMI of $985.0 million, after paying the initial purchasers' commissions and expenses, were used to redeem all of the 6 \( ^{3} \) / \( _{4} \) % Notes, 7 \( ^{3} \) / \( _{4} \) % Notes and 8 \( ^{3} \) / \( _{8} \) % Notes in October 2015. The remaining net proceeds were used for general corporate purposes, including acquisitions. We recorded a charge to other expense (income), net of $25.1 million in the fourth quarter of 2015 related to the early extinguishment of this debt. This charge consists of call premiums, original issue discounts and unamortized deferred financing costs.

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 "Special Purpose Subsidiaries"). The Special Purpose Subsidiaries use the accounts receivable balances to collateralize loans obtained from certain financial institutions. The 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 Sheet, (ii) our Consolidated Statement of Operations reflects 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 Statement of Cash Flows. Iron Mountain Information Management, LLC ("IMIM") retains the responsibility of servicing the accounts receivable balances pledged as collateral in this transaction and IMI provides a performance guaranty. The Accounts Receivable Securitization Program terminates on March 6, 2018, at which point all obligations become due. 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, 2015, the maximum availability allowed and amount outstanding under the Accounts Receivable Securitization Program was $205.9 million. The interest rate in effect under the Accounts Receivable Securitization Program was 1.3% as of December 31, 2015. Commitment fees at a rate of 40 basis points are charged on amounts made available but not borrowed under the Accounts Receivable Securitization Program.



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 for the years ended December 31, 2013, 2014 and 2015, are as follows (in thousands):

<table><tr><td rowspan="2"></td><td colspan="4">Year Ended December 31,</td></tr><tr><td>2013</td><td>2014</td><td>2015</td><td></td></tr><tr><td>Commitment fees and letters of credit fees</td><td>$ 3,167</td><td>$ 3,322</td><td>$ 3,743</td><td></td></tr></table>

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.

## Acquisitions

In December 2015, in order to expand our offerings in our Adjacent Businesses operating segment, we acquired 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 $74.2 million.

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 $16.1 million. Of the total consideration, approximately $8.9 million was funded by us, while the remaining $7.2 million was contributed by the noncontrolling interest shareholder of our business in India. The amount contributed by our noncontrolling interest shareholder is presented as a source of cash within debt (repayment to) financing from and equity (distribution to) contribution from noncontrolling interests, net in our Consolidated Statement of Cash Flows.

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 $27.6 million. 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 $1.0 million to $5.4 million.

## Proposed Recall Acquisition

On June 8, 2015, we entered into the Recall Agreement with Recall to acquire Recall by way of the Scheme. Under the terms of the Recall Agreement, Recall shareholders are entitled to receive the Cash Supplement as well as either (1) 0.1722 shares of our common stock for each Recall share or (2) the Cash Election. The Cash Election is subject to the Cash Election Cap. Amounts paid to Recall shareholders that represent the Cash Supplement are excluded from the calculation of the Cash Election Cap. Assuming a sufficient number of Recall shareholders elect the Cash Election such that we pay the Cash Election Cap, we expect to issue approximately 50.7 million shares of our common stock and, based on the exchange rate between the United States dollar and the Australian dollar as of February 19, 2016, pay approximately US$323.0 million to Recall shareholders in connection with the Recall Transaction which, based on the closing price of our common stock as of February 19, 2016, would result in a total purchase price to Recall shareholders of approximately $1,791.0 million. Completion of the Scheme is subject to customary closing conditions, including among others, (i) approval by Recall shareholders of the Scheme by the requisite majority under the Australian Corporations Act, (ii) expiration or earlier termination of any applicable waiting period and receipt of regulatory consents, approvals and clearances, in each case, under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and under relevant antitrust/competition and foreign investment legislation in other relevant jurisdictions, (iii) the absence of any final, non-appealable order, decree or law preventing, making illegal or prohibiting the completion of the Recall Transaction, (iv) approval from the NYSE to the listing of additional shares of our common stock to be issued in the Recall Transaction, (v) the establishment of a secondary listing on the ASX to allow Recall shareholders to trade our common stock via CHESS Depository Interests on the ASX, (vi) Recall's delivery of tax opinions in accordance and in compliance with certain tax matter agreements to which Recall is a party and (vii) no events having occurred that would have a material adverse effect on Recall or us. We continue to work toward closing of the Recall Transaction and related integration planning.



There are significant costs associated with the Recall Transaction. We currently estimate total operating and capital 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 approximately $80.0 million of Recall Deal Close Costs and approximately $300.0 million of Recall Integration Costs. Of these amounts, approximately $47.1 million was incurred through December 31, 2015 ($24.7 million of Recall Deal Close Costs and $22.4 million of Recall Integration Costs), including approximately $47.0 million of operating expenditures and approximately $0.1 million of capital expenditures.

Additionally, upon closing of the Recall Transaction we will incur costs associated with (i) the cash components of the purchase price noted above and (ii) the payoff of outstanding borrowings under Recall’s existing revolving credit facility.

We expect the total cost to close the Recall Transaction (including Recall Deal Close Costs, the cash components of the purchase price and the payoff of Recall’s revolving credit facility, but excluding Recall Integration Costs) to be approximately $1,100.0 million. We intend to fund these costs through a combination of cash on hand, borrowings under our Revolving Credit Facility and, as necessary, public or private debt financing.

## Contractual Obligations

The following table summarizes our contractual obligations as of December 31, 2015 and the anticipated effect of these obligations on our liquidity in future years (in thousands):

<table><tr><td rowspan="2"></td><td colspan="6">Payments Due by Period</td></tr><tr><td colspan="2">Total</td><td colspan="2">Less than 1 Year</td><td>1-3 Years</td><td>3-5 Years</td></tr><tr><td>Capital Lease Obligations</td><td>$ 235,348</td><td>$ 43,705</td><td>$ 68,086</td><td>$ 40,502</td><td>$ 83,055</td><td></td></tr><tr><td>Long-Term Debt Obligations (excluding Capital Lease Obligations)</td><td>4,668,629</td><td>44,363</td><td>290,854</td><td>1,992,898</td><td>2,340,514</td><td></td></tr><tr><td>Interest Payments(1)</td><td>1,561,177</td><td>254,626</td><td>460,373</td><td>424,060</td><td>422,118</td><td></td></tr><tr><td>Operating Lease Obligations(2)</td><td>2,000,010</td><td>215,530</td><td>397,937</td><td>350,165</td><td>1,036,378</td><td></td></tr><tr><td>Purchase and Asset Retirement Obligations</td><td>109,890</td><td>54,424</td><td>36,339</td><td>3,762</td><td>15,365</td><td></td></tr><tr><td>Total(3)</td><td>$ 8,575,054</td><td>$ 612,648</td><td>$ 1,253,589</td><td>$ 2,811,387</td><td>$ 3,897,430</td><td></td></tr></table>

(1) Amounts include variable rate interest payments, which are calculated utilizing the applicable interest rates as of December 31, 2015; see Note 4 to Notes to Consolidated Financial Statements included in this Annual Report. Amounts also include interest on capital leases.

(2) These amounts are net of sublease income of $28.6 million in total (including $4.8 million, $7.7 million, $5.8 million and $10.3 million, in less than 1 year, 1-3 years, 3-5 years and more than 5 years, respectively).

(3) The table above excludes $47.7 million in uncertain tax positions as we are unable to make reliable estimates of the period of cash settlement, if any, with the respective taxing authorities.

We expect to meet our cash flow requirements for the next twelve months from cash generated from operations, existing cash, cash equivalents, borrowings under the Credit Agreement and other financings, which may include senior or senior subordinated notes, secured credit facilities, securitizations and mortgage or capital lease financings, and the issuance of equity. We expect to meet our long-term cash flow requirements using the same means described above. We are highly leveraged and expect to continue to be highly leveraged for the foreseeable future. As a REIT, we expect our long-term capital allocation strategy will naturally shift towards lower leverage, though our leverage has increased over the last several fiscal years to fund the costs of the REIT conversion and the Recall Transaction.

## 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 in 2021 through 2033, of $70.8 million at December 31, 2015 to reduce future federal taxable income, on which $3.0 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 taxable year. We have state net operating loss carryforwards, which expire from 2016 through 2034, on which an insignificant state tax benefit is expected to be realized. We have assets for foreign net operating losses of $66.2 million, with various expiration dates (and in some cases no expiration date), subject to a valuation allowance of approximately 91%.

## Inflation

Certain of our expenses, such as wages and benefits, insurance, occupancy costs and equipment repair and replacement, are subject to normal inflationary pressures. Although to date we have been able to offset inflationary cost increases through increased operating efficiencies, the negotiation of favorable long-term real estate leases and customer contracts which contain provisions for inflationary price escalators, we can give no assurance that we will be able to offset any future inflationary cost increases through similar efficiencies, leases or increased storage rental or service charges.

## Item 7A. Quantitative and Qualitative Disclosures About Market Risk.

## Credit Risk

Financial instruments that potentially subject us to credit risk consist principally of cash and cash equivalents (including money market funds and time deposits) and accounts receivable. The only significant concentrations of liquid investments as of December 31, 2015 related to cash and cash equivalents held in time deposits with four global banks, all of which we consider to be large, highly-rated investment-grade institutions. As per our risk management investment policy, we limit exposure to concentration of credit risk by limiting the amount invested in any one mutual fund to a maximum of $50.0 million or in any one financial institution to a maximum of $75.0 million. As of December 31, 2015, our cash and cash equivalents balance was $128.4 million, including money market funds and time deposits amounting to $18.6 million.

## Interest Rate Risk

Given the recurring nature of our revenues and the long-term nature of our asset base, we have the ability and the preference to use long-term, fixed interest rate debt to finance our business at attractive rates, thereby helping to preserve our long-term returns on invested capital. We target approximately 75% of our debt portfolio to be fixed with respect to interest rates. Occasionally, we will 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, 2015, we had $1,238.1 million of variable rate debt outstanding with a weighted average variable interest rate of approximately 2.3%, and $3,665.9 million of fixed rate debt outstanding. As of December 31, 2015, approximately 75% 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, 2015 would have been reduced by approximately $10.5 million. See Note 4 to Notes to Consolidated Financial Statements included in this Annual Report for a discussion of our long-term indebtedness, including the fair values of such indebtedness as of December 31, 2015.

## Currency Risk

Our international investments may be subject to risks and uncertainties related to fluctuations in currency valuation. Our reporting currency is the United States dollar. However, our international revenues and expenses are generated in the currencies of the countries in which we operate, primarily the British pound sterling, Euro, Canadian dollar, Brazilian real, Australian dollar and the Russian ruble. 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 Switzerland, 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 currency valuations. 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 and continental Europe. IME has financed its capital needs through direct borrowings in British pounds sterling under the GBP Notes. Similarly, Canada Company has financed its capital needs through direct borrowings in Canadian dollars under the Credit Agreement and the CAD Notes. This creates a tax efficient natural currency hedge. We utilized a portion of our previously outstanding  $ 6^{3}/_{4}\% \)  Notes and, subsequent to their redemption in October 2015, continue to utilize a portion of Euro denominated borrowings by IMI under the Revolving Credit Facility, to effectively hedge our outstanding intercompany loans denominated in Euros. We designated a portion of our  $ 6^{3}/_{4}\% \)  Notes issued by IMI and continue to designate a portion of 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 3.3 million (3.3 million, net of tax) of foreign exchange gains related to the "marking-to-market" of such debt to currency translation adjustments which is a component of accumulated other comprehensive items, net included in stockholders' equity for the year ended December 31, 2015. As of December 31, 2015, cumulative net gains of 17.1 million, net of tax are recorded in accumulated other comprehensive items, net associated with this net investment hedge.

We have also entered into a number of separate forward contracts to hedge our exposures in Euros, British pounds sterling and Australian dollars. As of December 31, 2015, however, we had no forward contracts outstanding. In the future, we may enter into new forward contracts to hedge movements in the underlying currencies. At the maturity of any forward contract, we may enter into a new forward contract to hedge movements in the underlying currencies. At the time of settlement, we either pay or receive the net settlement amount from any forward contract and recognize this amount in other expense (income), net in the accompanying statements of operations as a realized foreign exchange gain or loss. At the end of each month, we mark the outstanding forward contracts to market and record an unrealized foreign exchange gain or loss for the mark-to-market valuation. We have not designated forward contracts as hedges. During the year ended December 31, 2015, there was $22.7 million in net cash payments included in cash from operating activities from continuing operations related to settlements associated with foreign currency forward contracts. We recorded net losses in connection with forward contracts of $20.3 million in the accompanying statement of operations as of December 31, 2015. As of December 31, 2015, 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 exchange rates on our net investment in foreign subsidiaries is reflected in the "Accumulated Other Comprehensive Items, net" component of equity. A 10% depreciation in year-end 2015 functional currencies, relative to the United States dollar, would result in a reduction in our equity of approximately $49.8 million.

## Item 9A. Controls and Procedures.

## Disclosure Controls and Procedures

The term "disclosure controls and procedures" is defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act. These rules refer to the controls and other procedures of a company that are designed to ensure that information is recorded, processed, summarized and communicated to management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding what is required to be disclosed by a company in the reports that it files under the Exchange Act. As of December 31, 2015 (the "Evaluation Date"), we carried out an evaluation, under the supervision and with the participation of our management, including our chief executive officer and chief financial officer, of the effectiveness of our disclosure controls and procedures. Based upon that evaluation, our chief executive officer and chief financial officer concluded that, as of the Evaluation Date, our disclosure controls and procedures are effective.

## Management's Report on Internal Control over Financial Reporting

Our management, with the participation of our principal executive officer and principal financial officer, is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act. Our internal control system is designed to provide reasonable assurance to our management and board of directors regarding the preparation and fair presentation of published financial statements. Due to their inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Projections of any evaluation of effectiveness to future periods are subject to the risks that controls may become inadequate because of changes in conditions or that the degree of compliance with policies or procedures may deteriorate. Under the supervision and with the participation of our management, including our chief executive officer and chief financial officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this evaluation, our management concluded that our internal control over financial reporting was effective as of December 31, 2015.

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



# REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of Iron Mountain Incorporated
Boston, Massachusetts

We have audited the internal control over financial reporting of Iron Mountain Incorporated and subsidiaries (the "Company") as of December 31, 2015, based on criteria established in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company's internal control over financial reporting is a process designed by, or under the supervision of, the company's principal executive and principal financial officers, or persons performing similar functions, and effected by the company's board of directors, management, and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2015, based on the criteria established in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated financial statements and financial statement schedule as of and for the year ended December 31, 2015 of the Company and our report dated February 26, 2016 expressed an unqualified opinion on those financial statements and financial statement schedule.

# REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of Iron Mountain Incorporated
Boston, Massachusetts

We have audited the accompanying consolidated balance sheets of Iron Mountain Incorporated and subsidiaries (the "Company") as of December 31, 2015 and 2014, and 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, 2015. Our audits also included the financial statement schedule listed in the Index at Item 15. These financial statements and financial statement schedule are the responsibility of the Company's management. Our responsibility is to express an opinion on the financial statements and financial statement schedule based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of Iron Mountain Incorporated and subsidiaries as of December 31, 2015 and 2014, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2015, in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, such financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly, in all material respects, the information set forth therein.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the Company's internal control over financial reporting as of December 31, 2015, based on the criteria established in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 26, 2016 expressed an unqualified opinion on the Company's internal control over financial reporting.

# IRON MOUNTAIN INCORPORATED
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
DECEMBER 31, 2015
(In thousands, except share and per share data)

## 1. Nature of Business

The accompanying financial statements represent the consolidated accounts of Iron Mountain Incorporated, a Delaware corporation ("IMI") and its subsidiaries ("we" or "us"). We store records, primarily physical records and data backup media, and provide information management services in various locations throughout North America, Europe, Latin America and Asia Pacific. We have a diversified customer base consisting of commercial, legal, banking, healthcare, accounting, insurance, entertainment and government organizations.

We have been organized and operating as a real estate investment trust for federal income tax purposes ("REIT") effective for our taxable year beginning January 1, 2014.

## 2. Summary of Significant Accounting Policies

## a. Principles of Consolidation

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

## b. Use of Estimates

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

## c. 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, 2014, we had $33,860 of restricted cash associated with a collateral trust agreement with our insurance carrier related to our workers' compensation self-insurance program included in current assets on our Consolidated Balance Sheet. The restricted cash consisted primarily of United States Treasuries. We had no restricted cash at December 31, 2015.

## d. Foreign Currency

Local currencies are the functional currencies for our operations outside the United States, with the exception of certain foreign holding companies and our financing centers in Switzerland, whose functional currency is the United States dollar. In those instances where the local currency is the functional currency, assets and liabilities are translated at period-end exchange rates, and revenues and expenses are translated at average exchange rates for the applicable period. Resulting translation adjustments are reflected in the accumulated other comprehensive items, net component of Iron Mountain Incorporated Stockholders' Equity and Noncontrolling Interests in the accompanying Consolidated Balance Sheets. The gain or loss on foreign currency transactions, calculated as the difference between the historical exchange rate and the exchange rate at the applicable measurement date, including those related to (1) our previously outstanding  $ 7^{1}/_{4}\% \)  GBP Senior Subordinated Notes due 2014 (the " $ 7^{1}/_{4}\% \)  Notes"), (2) our previously outstanding  $ 6^{3}/_{4}\% \)  Euro Senior Subordinated Notes due 2018 (the " $ 6^{3}/_{4}\% \)  Notes"), (3) borrowings in certain foreign currencies under our Revolving Credit Facility and our Former Revolving Credit Facility (each as defined in Note 4) and (4) certain foreign currency denominated intercompany obligations of our foreign subsidiaries to us and between our foreign subsidiaries, which are not considered permanently invested, are included in other expense (income), net, in the accompanying Consolidated Statements of Operations.

The total loss on foreign currency transactions for the years ended December 31, 2013, 2014 and 2015 is as follows:

<table><tr><td rowspan="2"></td><td colspan="4">Year Ended December 31,</td></tr><tr><td>2013</td><td>2014</td><td>2015</td><td></td></tr><tr><td>Total loss on foreign currency transactions</td><td>$ 36,201</td><td>$ 58,316</td><td>$ 70,851</td><td></td></tr></table>

## e. 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 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. As of December 31, 2014 and 2015, none of our derivative instruments contained credit-risk related contingent features.

## f. Property, Plant and Equipment

Property, plant and equipment are stated at cost and depreciated using the straight-line method with the following useful lives (in years):

<table><tr><td></td><td>Range</td></tr><tr><td>Buildings and building improvements</td><td>5 to 40</td></tr><tr><td>Leasehold improvements</td><td>5 to 10 or life of the lease (whichever is shorter)</td></tr><tr><td>Racking</td><td>1 to 20 or life of the lease (whichever is shorter)</td></tr><tr><td>Warehouse equipment/vehicles</td><td>1 to 10</td></tr><tr><td>Furniture and fixtures</td><td>3 to 10</td></tr><tr><td>Computer hardware and software</td><td>2 to 5</td></tr></table>

Property, plant and equipment (including capital leases in the respective category), at cost, consist of the following:

<table><tr><td rowspan="2"></td><td colspan="2">December 31,</td></tr><tr><td>2014</td><td>2015</td></tr><tr><td>Land</td><td>$ 205,463</td><td>$ 218,174</td></tr><tr><td>Buildings and building improvements</td><td>1,409,330</td><td>1,507,224</td></tr><tr><td>Leasehold improvements</td><td>467,176</td><td>447,449</td></tr><tr><td>Racking</td><td>1,559,383</td><td>1,556,749</td></tr><tr><td>Warehouse equipment/vehicles</td><td>341,393</td><td>335,728</td></tr><tr><td>Furniture and fixtures</td><td>53,189</td><td>50,307</td></tr><tr><td>Computer hardware and software</td><td>501,882</td><td>515,688</td></tr><tr><td>Construction in progress</td><td>130,889</td><td>112,917</td></tr><tr><td></td><td>$ 4,668,705</td><td>$ 4,744,236</td></tr></table>

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, 2013, 2014 and 2015, we capitalized $39,487, $19,419 and $26,201 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.

## 2. Summary of Significant Accounting Policies (Continued)

During the years ended December 31, 2013 and 2014, we wrote off previously deferred software costs 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, by segment as follows:

<table><tr><td rowspan="2"></td><td colspan="4">Year Ended December 31,</td></tr><tr><td>2013</td><td>2014</td><td>2015</td><td></td></tr><tr><td>North American Records and Information Management Business</td><td>$ 800</td><td>$ 1,000</td><td>$ —</td><td></td></tr><tr><td>North American Data Management Business</td><td>—</td><td>—</td><td>—</td><td></td></tr><tr><td>Western European Business</td><td>—</td><td>300</td><td></td><td></td></tr><tr><td>Other International Business</td><td>—</td><td>—</td><td>—</td><td></td></tr><tr><td>Corporate and Other Business</td><td>300</td><td>—</td><td>—</td><td></td></tr><tr><td></td><td>$ 1,100</td><td>$ 1,300</td><td>$ —</td><td></td></tr></table>

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 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:

<table><tr><td rowspan="2"></td><td colspan="2">December 31,</td></tr><tr><td>2014</td><td>2015</td></tr><tr><td>Asset Retirement Obligations, beginning of the year</td><td>$ 11,809</td><td>$ 12,897</td></tr><tr><td>Liabilities Incurred</td><td>1,366</td><td>1,030</td></tr><tr><td>Liabilities Settled</td><td>(1,199)</td><td>(966)</td></tr><tr><td>Accretion Expense</td><td>1,121</td><td>1,241</td></tr><tr><td>Foreign Currency Exchange Movement</td><td>(200)</td><td>(205)</td></tr><tr><td>Asset Retirement Obligations, end of the year</td><td>$ 12,897</td><td>$ 13,997</td></tr></table>

## g. Goodwill and Other 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. Separable intangible assets that are not deemed to have indefinite lives are amortized over their useful lives. We annually, or more frequently if events or circumstances warrant, assess whether a change in the lives over which our intangible assets are amortized is necessary.

## 2. Summary of Significant Accounting Policies (Continued)

We have selected October 1 as our annual goodwill impairment analysis date. We performed our annual goodwill impairment analysis as of October 1, 2013, 2014 and 2015 and concluded that goodwill was not impaired as of those dates. As of December 31, 2015, no factors were identified that would alter our October 1, 2015 goodwill analysis. In making this assessment, we relied on 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. When changes occur in the composition of one or more reporting units, the goodwill is reassigned to the reporting units affected based on their relative fair values.

Our reporting units at which level we performed our goodwill impairment analysis as of October 1, 2014 were as follows: (1) North American Records and Information Management; (2) technology escrow services that protect and manage source code (the “Intellectual Property Management” reporting unit); (3) the storage, assembly and detailed reporting of customer marketing literature and delivery to sales offices, trade shows and prospective customers’ sites based on current and prospective customer orders (the “Fulfillment Services” reporting unit); (4) North American Data Management; (5) Adjacent Businesses (which was formerly referred to as the "Emerging Businesses" reporting unit and, at the time of our October 1, 2014 goodwill impairment analysis, primarily related to our data center business in the United States and which is a component of our Corporate and Other Business segment); (6) the United Kingdom, Ireland, Norway, Austria, Belgium, France, Germany, Netherlands, Spain and Switzerland (the “New Western Europe” reporting unit); (7) the remaining countries in Europe in which we operate, excluding Russia, Ukraine and Denmark (the “Emerging Markets - Eastern Europe” reporting unit); (8) Latin America; (9) Australia and Singapore; (10) China and Hong Kong (the "Greater China" reporting unit); (11) India; and (12) Russia, Ukraine and Denmark.

The carrying value of goodwill, net for each of our reporting units as of December 31, 2014 was as follows:

<table><tr><td></td><td>Carrying Value as of December 31, 2014</td></tr><tr><td>North American Records and Information Management(1)</td><td>1,397,484</td></tr><tr><td>Intellectual Property Management(1)</td><td>38,491</td></tr><tr><td>Fulfillment Services(1)</td><td>3,247</td></tr><tr><td>North American Data Management(2)</td><td>375,957</td></tr><tr><td>Adjacent Businesses(3)</td><td>—</td></tr><tr><td>New Western Europe(4)(6)</td><td>354,049</td></tr><tr><td>Emerging Markets - Eastern Europe(5)</td><td>87,408</td></tr><tr><td>Latin America(5)</td><td>107,240</td></tr><tr><td>Australia and Singapore(5)</td><td>55,779</td></tr><tr><td>Greater China(5)</td><td>3,500</td></tr><tr><td>India(5)</td><td>—</td></tr><tr><td>Russia, Ukraine and Denmark(5)</td><td>628</td></tr><tr><td>Total</td><td>2,423,783</td></tr></table>

## 2. Summary of Significant Accounting Policies (Continued)

(6) As of December 31, 2014, the goodwill associated with our operations in Norway was included in the New Western Europe reporting unit. As of December 31, 2015, as a result of changes in the senior management of our business in Norway, which impacted both our reportable operating segments (see Note 9 for a description of our reportable operating segments) as well as our reporting units (described more fully below), the goodwill associated with our operations in Norway is included in the Emerging Markets - Europe reporting unit (defined below).

Beginning January 1, 2015, as a result of the changes in our reportable operating segments associated with our reorganization (described more fully in Note 9), we reassessed the composition of our reporting units. As part of this reassessment, we determined that our North American Records and Information Management Business segment now consists of two reporting units: (1) North American Records and Information Management (which includes Intellectual Property Management and Fulfillment Services) and (2) North American Secure Shredding. Also as part of this reassessment, we determined that our Western European Business segment consisted of two reporting units: (1) the United Kingdom, Ireland and Norway (the "UKI and Norway" reporting unit) and (2) Austria, Belgium, France, Germany, Netherlands, Spain and Switzerland (the "Continental Western Europe" reporting unit). We have reassigned goodwill associated with the reporting units impacted by the reorganization among the new reporting units on a relative fair value basis. The fair value of each of our new reporting units noted above was determined based on the application of a combined weighted average approach of fair value multiples of revenue and earnings and discounted cash flow techniques.

As a result of the change in the composition of our reporting units noted above, we concluded that we had an interim triggering event, and, therefore, during the first quarter of 2015, we performed an interim goodwill impairment test, as of January 1, 2015, for the North American Records and Information Management, North American Secure Shredding, UKI and Norway and Continental Western Europe reporting units. We concluded that the goodwill for each of our new reporting units was not impaired as of such date.

Our reporting units at which level we performed our goodwill impairment analysis as of October 1, 2015 were as follows: (1) North American Records and Information Management; (2) North American Secure Shredding; (3) North American Data Management; (4) Adjacent Businesses - Data Centers (which consists primarily of our data center business in the United States); (5) Adjacent Businesses - Consumer Storage (which consists of a consumer storage business with operations in the United States acquired in April 2015); (6) UKI and Norway; (7) Continental Western Europe; (8) Emerging Markets - Eastern Europe; (9) Latin America; (10) Australia and Singapore; (11) Greater China; (12) India; and (13) Russia, Ukraine and Denmark. We concluded that the goodwill for each of our reporting units was not impaired as of such date.

During the fourth quarter of 2015, as a result of changes in the management of certain of our businesses in Europe and Asia Pacific, we reassessed the composition of our reporting units as well as our reportable operating segments (see Note 9 for a description of our reportable operating segments). As part of this reassessment, we determined that our former Russia, Ukraine and Denmark reporting unit, as well as our business in Norway (which was previously managed along with our operations in the United Kingdom and Ireland within our UKI and Norway reporting unit) are being managed in conjunction with the businesses included in our Emerging Markets - Eastern Europe reporting unit. This newly formed reporting unit, which consists of (i) our former Emerging Markets - Eastern Europe reporting unit, (ii) our former Russia, Ukraine and Denmark reporting unit, and (iii) our business in Norway is referred to herein as the "Emerging Markets - Europe" reporting unit. Our businesses in the United Kingdom and Ireland will continue to be managed as a separate reporting unit (the "UKI" reporting unit). Additionally, we determined that our business in Singapore, which was previously managed along with our operations in Australia, is now being managed along with our businesses in our Greater China reporting unit. This newly formed reporting unit, which includes (i) our former Greater China reporting unit and (ii) our business in Singapore is referred to herein as the "Southeast Asia" reporting unit. Australia will be managed on a standalone basis (the "Australia" reporting unit).

As a result of the change in the composition of our reporting units noted above, we concluded that we had an interim triggering event, and, therefore, during the fourth quarter of 2015, we performed an interim goodwill impairment test, for the UKI, Emerging Markets-Europe, Australia and Southeast Asia reporting units. We concluded that the goodwill for each of our new reporting units was not impaired as of such date.

Additionally, in December 2015, we acquired Crozier Fine Arts ("Crozier"), a storage, logistics and transportation business for high value paintings, photographs and other types of art. We determined that Crozier will be managed as a separate component within our Adjacent Businesses operating segment and, therefore, constitutes a separate reporting unit (the "Adjacent Businesses - Fine Arts" reporting unit).

The carrying value of goodwill, net for each of our reporting units as of December 31, 2015 was as follows:

Reporting unit valuations have been determined using a combined approach based on the present value of future cash flows and market multiples of revenues and earnings. The income approach incorporates many assumptions including future growth rates, discount 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) Total fair value and other adjustments primarily include $(32,265) in net adjustments to deferred income taxes and $(443) related to property, plant and equipment and other assumed liabilities, as well as $(1,300) of cash received related to certain 2013 acquisitions.

(2) Total fair value and other adjustments primarily include $622 in net adjustments to deferred income taxes and $(5,036) related to customer relationships and acquisition costs and other assumed liabilities (which represent adjustments within the applicable measurement period, to provisional amounts recognized in purchase accounting), as well as $3,692 of cash paid related to certain 2014 acquisitions.

## h. Long-Lived Assets

We review long-lived assets and all amortizable 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 the operation is determined to be unable to recover the carrying amount of its 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.

Consolidated loss on disposal/write-down of property, plant and equipment (excluding real estate), net was $430 for the year ended December 31, 2013 and consisted of $1,700 of asset write-offs in our North American Records and Information Management Business segment, approximately $300 of asset write-offs in our Corporate and Other Business segment, approximately $600 of asset write-offs associated with our Western European Business segment and approximately $300 of asset write-offs associated with our Other International Business segment, partially offset by gains of approximately $2,500 on the retirement of leased vehicles accounted for as capital lease assets primarily associated with our North American Records and Information Management Business segment. Consolidated loss on disposal/write-down of property, plant and equipment (excluding real estate), net was $1,065 for the year ended December 31, 2014 and consisted primarily of losses associated with the write-off of certain software associated with our North American Records and Information Management Business segment. Consolidated loss 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 approximately $1,800 of losses associated with the write-off of certain property in our Western European Business segment, as well as $1,500 of losses associated with the write-off of certain property in our North American Records and Information Management 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.

## i. Customer Relationship Intangible Assets, Customer Inducements and Other 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 (weighted average of 20 years at December 31, 2015). 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 charges ("Move Costs"), are amortized over periods ranging from one to 30 years (weighted average of 25 years at December 31, 2015), 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 one to 15 years (weighted average of six years at December 31, 2015) to the storage and service revenue line items 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 intangible assets, including noncompetition agreements and trademarks, are capitalized and amortized over periods ranging from five to 10 years (weighted average of seven years at December 31, 2015).

The gross carrying amount and accumulated amortization are as follows:

<table><tr><td rowspan="2">Gross Carrying Amount</td><td colspan="2">December 31,</td></tr><tr><td>2014</td><td>2015</td></tr><tr><td>Customer relationship intangible assets and Customer Inducements</td><td>$ 904,866</td><td>$ 937,174</td></tr><tr><td>Other intangible assets (included in other assets, net)</td><td>10,630</td><td>11,111</td></tr><tr><td>Accumulated Amortization</td><td></td><td></td></tr><tr><td>Customer relationship intangible assets and Customer Inducements</td><td>$ 297,029</td><td>$ 333,860</td></tr><tr><td>Other intangible assets (included in other assets, net)</td><td>8,608</td><td>8,325</td></tr></table>

## 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.

In the fourth quarter of 2015, we adopted Accounting Standards Update No. 2015-03 (“ASU 2015-03”, which is discussed in greater detail in Note 2.w). ASU 2015-03 required retrospective application. Therefore, our financial statements and notes to those financial statements contained herein have been adjusted to reflect the impact of adopting ASU 2015-03. The net carrying value of deferred financing costs (including deferred financing costs associated with the Credit Agreement and the Former Credit Agreement, each as discussed and defined in Note 4) which were formerly presented within Other Assets, net are now presented within Long-term Debt, net of current portion on our Consolidated Balance Sheets.

As of December 31, 2014 and 2015, gross carrying amount of deferred financing costs was $63,033 and $70,549, respectively, and accumulated amortization of those costs was $15,956 and $12,250, respectively.

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

<table><tr><td rowspan="2"></td><td colspan="2">Estimated Amortization of Deferred Financing Costs</td></tr><tr><td>2016</td><td>10,525</td></tr><tr><td>2017</td><td></td><td>10,525</td></tr><tr><td>2018</td><td></td><td>10,289</td></tr><tr><td>2019</td><td></td><td>9,066</td></tr><tr><td>2020</td><td></td><td>6,685</td></tr></table>

## 1. 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, or Document Management Solutions ("DMS"), 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, and detailed reporting of customer marketing literature and delivery to sales offices, trade shows and prospective customers' sites based on current and prospective customer orders; (9) consulting services; and (10) 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, 2015, have historically not been significant.

## 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 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 over the remaining lives of the respective leases.

## n. Stock-Based Compensation

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

## 2. Summary of Significant Accounting Policies (Continued)

Stock-based compensation expense for Employee Stock-Based Awards included in the accompanying Consolidated Statements of Operations for the years ended December 31, 2013, 2014 and 2015 was $30,354 ($22,085 after tax or $0.12 per basic and $0.11 per diluted share), $29,624 ($21,886 after tax or $0.11 per basic and diluted share) and $27,585 ($19,679 after tax or $0.09 per basic and diluted share), respectively.

Stock-based compensation expense for Employee Stock-Based Awards included in the accompanying Consolidated Statements of Operations related to continuing operations is as follows:

<table><tr><td rowspan="2"></td><td colspan="4">Year Ended December 31,</td></tr><tr><td>2013</td><td colspan="2">2014</td><td>2015</td></tr><tr><td>Cost of sales (excluding depreciation and amortization)</td><td>$     293</td><td>$     680</td><td>$     220</td><td></td></tr><tr><td>Selling, general and administrative expenses</td><td>30,061</td><td>28,944</td><td>27,365</td><td></td></tr><tr><td>Total stock-based compensation</td><td>$     30,354</td><td>$     29,624</td><td>$     27,585</td><td></td></tr></table>

The benefits associated with the tax deductions in excess of recognized compensation cost are required to be reported as financing activities in the accompanying Consolidated Statements of Cash Flows. This requirement impacts reported operating cash flows and reported financing cash flows. As a result, net financing cash flows from continuing operations included $2,389, $ (60) and $327 for the years ended December 31, 2013, 2014 and 2015, respectively, from the benefits (deficiency) of tax deductions compared to recognized compensation cost. The tax benefit of any resulting excess tax deduction increases the Additional Paid-in Capital ("APIC") pool. Any resulting tax deficiency is deducted from the APIC pool.

## 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. Certain of the options we issue become exercisable ratably over a period of 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. As of December 31, 2015, ten-year vesting options represented 7.4% of total outstanding options. Certain of the options we issue become exercisable ratably over a period of 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. As of December 31, 2015, five-year vesting options represented 41.0% of total outstanding options. The remainder of options we issue become exercisable ratably over a period of 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. As of December 31, 2015, three-year vesting options represented 51.6% of total outstanding options. Our non-employee directors are considered employees for purposes of our stock option plans and stock option reporting. Options granted to our non-employee directors become exercisable immediately upon grant.

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 his or her 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 (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 7,750,000. The 2014 Plan permits us to continue to grant awards through January 20, 2025.

A total of 43,253,839 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 2014 Plan or the ESPP, at December 31, 2015 was 455,811.

## 2. Summary of Significant Accounting Policies (Continued)

The weighted average fair value of options granted in 2013, 2014 and 2015 was $7.69, $5.70 and $4.84 per share, respectively. These values were estimated on the date of grant using the Black-Scholes option pricing model. The following table summarizes the weighted average assumptions used for grants in the year ended December 31:

<table><tr><td>Weighted Average Assumptions</td><td>2013</td><td>2014</td><td>2015</td></tr><tr><td>Expected volatility</td><td>33.8%</td><td>34.0%</td><td>28.4%</td></tr><tr><td>Risk-free interest rate</td><td>1.13%</td><td>2.04%</td><td>1.70%</td></tr><tr><td>Expected dividend yield</td><td>3%</td><td>4%</td><td>5%</td></tr><tr><td>Expected life</td><td>6.3 years</td><td>6.7 years</td><td>5.4 years</td></tr></table>

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.

A summary of option activity for the year ended December 31, 2015 is as follows:

<table><tr><td></td><td>Options</td><td>Weighted Average Exercise Price</td><td>Weighted Average Remaining Contractual Term (Years)</td><td>Aggregate Intrinsic Value</td></tr><tr><td>Outstanding at December 31, 2014</td><td>3,678,246</td><td>$ 23.37</td><td></td><td></td></tr><tr><td>Granted</td><td>787,224</td><td>42.21</td><td></td><td></td></tr><tr><td>Exercised</td><td>(719,300)</td><td>21.23</td><td></td><td></td></tr><tr><td>Forfeited</td><td>(34,144)</td><td>25.64</td><td></td><td></td></tr><tr><td>Expired</td><td>(23,212)</td><td>22.19</td><td></td><td></td></tr><tr><td>Outstanding at December 31, 2015</td><td>3,688,814</td><td>$ 27.79</td><td>5.56</td><td>$ 12,086</td></tr><tr><td>Options exercisable at December 31, 2015</td><td>2,386,622</td><td>$ 22.96</td><td>3.96</td><td>$ 11,472</td></tr><tr><td>Options expected to vest</td><td>1,241,658</td><td>$ 36.56</td><td>8.48</td><td>$ 595</td></tr></table>

The aggregate intrinsic value of stock options exercised for the years ended December 31, 2013, 2014 and 2015 is as follows:

<table><tr><td rowspan="2"></td><td colspan="4">Year Ended December 31,</td></tr><tr><td>2013</td><td>2014</td><td>2015</td><td></td></tr><tr><td>Aggregate intrinsic value of stock options exercised</td><td>$ 11,024</td><td>$ 23,178</td><td>$ 9,056</td><td></td></tr></table>

## Restricted Stock and Restricted Stock Units

Under our various equity compensation plans, we may also grant restricted stock or RSUs. Our restricted stock and RSUs generally have a vesting period of between three and five years from the date of grant. However, beginning in 2015, RSUs granted to our non-employee directors now 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 restricted stock and 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 PUs, the number of PUs earned is determined based on our performance against predefined targets of revenue or revenue growth and return on invested capital ("ROIC"). The number of PUs earned may range from 0% to 150% (for PUs granted prior to 2014) and 0% to 200% (for PUs granted in 2014 and thereafter) 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 either the one-year performance period (for PUs granted prior to 2014) or the three-year performance period (for PUs granted in 2014 and thereafter). Certain PUs granted in 2013, 2014 and 2015 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 growth 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. For those PUs subject to a one-year performance period, employees who subsequently terminate their employment after the end of the one-year performance period and on or after attaining age 55 and completing ten years of qualifying service (the "Retirement Criteria") shall immediately and completely vest in any PUs earned based on the actual achievement against the predefined targets as discussed above (but delivery of the shares remains deferred). As a result, PUs subject to a one-year performance period are generally expensed over the shorter of (1) the vesting period, (2) achievement of the Retirement Criteria, which may occur as early as January 1 of the year following the year of grant or (3) a maximum of three years. For those PUs subject to a three-year performance period, employees who terminate their employment during the performance period and on or after meeting the Retirement Criteria are eligible for pro-rated vesting, subject to the actual achievement against the predefined targets 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 subject to a three-year performance period 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.

Cash dividends accrued and paid on PUs for the years ended December 31, 2013, 2014 and 2015, are as follows:

<table><tr><td rowspan="2"></td><td colspan="4">Year Ended December 31,</td></tr><tr><td>2013</td><td>2014</td><td>2015</td><td></td></tr><tr><td>Cash dividends accrued on PUs</td><td>$ 681</td><td>$ 1,341</td><td>$ 874</td><td></td></tr><tr><td>Cash dividends paid on PUs</td><td>—</td><td>312</td><td>1,015</td><td></td></tr></table>

During the years ended December 31, 2013, 2014 and 2015, we issued 198,869, 225,429 and 159,334 PUs, respectively. The majority of our PUs are earned based on our performance against revenue or revenue growth and ROIC targets during their applicable performance period; therefore, we forecast the likelihood of achieving the predefined revenue, revenue growth 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 applicable performance period) or the actual PUs earned (at the one-year anniversary date for PUs granted prior to 2014 and at the three-year anniversary date for PUs granted in 2014 and thereafter) over the vesting period for each of the awards. For PUs earned based on a market condition, we utilize a Monte Carlo simulation to determine the fair value of these awards at the date of grant, and such fair value is expensed over the three-year performance period. As of December 31, 2015, we expected 0% and 100% achievement of the predefined revenue, revenue growth and ROIC targets associated with the awards of PUs made in 2014 and 2015, respectively.

The fair value of PUs that vested during the years ended December 31, 2013, 2014 and 2015, is as follows:

<table><tr><td rowspan="2"></td><td colspan="4">Year Ended December 31,</td></tr><tr><td>2013</td><td>2014</td><td>2015</td><td></td></tr><tr><td>Fair value of earned PUs that vested</td><td>$ 2,962</td><td>$ 1,216</td><td>$ 2,107</td><td></td></tr></table>

## 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, 2013, 2014 and 2015, there were 144,432 shares, 115,046 shares and 122,209 shares, respectively, purchased under the ESPP. As of December 31, 2015, we have 838,429 shares available under the ESPP.

As of December 31, 2015, unrecognized compensation cost related to the unvested portion of our Employee Stock-Based Awards was $35,303 and is expected to be recognized over a weighted-average period of 1.9 years.

We generally issue shares of our common stock for the exercises of stock options, restricted stock, 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 provision (benefit) for income taxes in the accompanying Consolidated Statements of Operations.

## 2. Summary of Significant Accounting Policies (Continued)

We had not previously provided incremental federal and certain state income taxes on net tax over book outside basis differences related to the earnings of our foreign subsidiaries because our intent, prior to our conversion to a REIT, was to reinvest our current and future undistributed earnings of certain foreign subsidiaries indefinitely outside the United States. As a result of our conversion to a REIT, it is no longer our intent to indefinitely reinvest our current and future undistributed foreign earnings outside the United States, and, therefore, during 2014, we recognized an increase in our tax provision from continuing operations in the amount of $46,356, representing incremental federal and state income taxes and foreign withholding taxes on such foreign earnings. We continue to provide incremental federal and state income taxes on net book over outside basis differences related to the earnings of our foreign subsidiaries. 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.

## 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 options, warrants or convertible securities) that were outstanding during the period, unless the effect is antidilutive.

The following table presents the calculation of basic and diluted income (loss) per share:

<table><tr><td rowspan="2"></td><td colspan="4">Year Ended December 31,</td></tr><tr><td>2013</td><td>2014</td><td>2015</td><td></td></tr><tr><td>Income (loss) from continuing operations</td><td>$     99,161</td><td>$     328,955</td><td>$     125,203</td><td></td></tr><tr><td>Total income (loss) from discontinued operations (see Note 14)</td><td>$     831</td><td>$      (209)</td><td>$      —</td><td></td></tr><tr><td>Net income (loss) attributable to Iron Mountain Incorporated</td><td>$     96,462</td><td>$     326,119</td><td>$     123,241</td><td></td></tr><tr><td>Weighted-average shares—basic</td><td>190,994,000</td><td>195,278,000</td><td>210,764,000</td><td></td></tr><tr><td>Effect of dilutive potential stock options</td><td>995,836</td><td>913,926</td><td>834,659</td><td></td></tr><tr><td>Effect of dilutive potential restricted stock, RSUs and PUs</td><td>422,045</td><td>557,269</td><td>519,426</td><td></td></tr><tr><td>Weighted-average shares—diluted</td><td>192,411,881</td><td>196,749,195</td><td>212,118,085</td><td></td></tr><tr><td>Earnings (losses) per share—basic:</td><td></td><td></td><td></td><td></td></tr><tr><td>Income (loss) from continuing operations</td><td>$     0.52</td><td>$     1.68</td><td>$     0.59</td><td></td></tr><tr><td>Total income (loss) from discontinued operations (see Note 14)</td><td>$      —</td><td>$      —</td><td>$      —</td><td></td></tr><tr><td>Net income (loss) attributable to Iron Mountain Incorporated—basic</td><td>$     0.51</td><td>$     1.67</td><td>$     0.58</td><td></td></tr><tr><td>Earnings (losses) per share—diluted:</td><td></td><td></td><td></td><td></td></tr><tr><td>Income (loss) from continuing operations</td><td>$     0.52</td><td>$     1.67</td><td>$     0.59</td><td></td></tr><tr><td>Total income (loss) from discontinued operations (see Note 14)</td><td>$      —</td><td>$      —</td><td>$      —</td><td></td></tr><tr><td>Net income (loss) attributable to Iron Mountain Incorporated—diluted</td><td>$     0.50</td><td>$     1.66</td><td>$     0.58</td><td></td></tr><tr><td>Antidilutive stock options, RSUs and PUs, excluded from the calculation</td><td>903,416</td><td>872,039</td><td>1,435,297</td><td></td></tr></table>

## 2. Summary of Significant Accounting Policies (Continued)

## 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:

<table><tr><td>Year Ended December 31,</td><td>Balance at Beginning of the Year</td><td>Credit Memos Charged to Revenue</td><td>Allowance for Bad Debts Charged to Expense</td><td>Other(1)</td><td>Deductions(2)</td><td>Balance at End of the Year</td></tr><tr><td>2013</td><td>$ 25,209</td><td>$ 49,483</td><td>$ 11,321</td><td>$ 3,612</td><td>$ (54,980)</td><td>$ 34,645</td></tr><tr><td>2014</td><td>34,645</td><td>47,137</td><td>14,209</td><td>(572)</td><td>(63,278)</td><td>32,141</td></tr><tr><td>2015</td><td>32,141</td><td>42,497</td><td>15,326</td><td>(4,511)</td><td>(54,006)</td><td>31,447</td></tr></table>

(1) Primarily consists of recoveries of previously written-off accounts receivable, allowances of businesses acquired and the impact associated with currency translation adjustments.

(2) Primarily consists of the issuance of credit memos and the write-off of accounts receivable.

## 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), restricted cash (primarily United States Treasuries) and accounts receivable. The only significant concentrations of liquid investments as of December 31, 2014 related to cash and cash equivalents and restricted cash held on deposit and as of December 31, 2015 related to cash and cash equivalents. At December 31, 2014, we had money market funds with two "Triple A" rated money market funds and time deposits with three global banks. At December 31, 2015, we had time deposits with four 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, 2014 and 2015, our cash and cash equivalents and restricted cash balance was $159,793 and $128,381, respectively. At December 31, 2014, our cash and cash equivalents included money market funds of $36,828, which were invested substantially in United States Treasuries and time deposits of $16,204. At December 31, 2015, our cash and cash equivalents included time deposits of $18,645.

## s. Fair Value Measurements

Entities are permitted under GAAP to elect to measure many financial instruments and certain other items at either fair value or cost. We have elected the cost measurement option.

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

The three levels of the fair value hierarchy are as follows:

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



# IRON MOUNTAIN INCORPORATED
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

# DECEMBER 31, 2015
(In thousands, except share and per share data)

## 2. Summary of Significant Accounting Policies (Continued)

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

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

The assets and liabilities carried at fair value and measured on a recurring basis as of December 31, 2014 and 2015, respectively, are as follows:

<table><tr><td rowspan="2"></td><td rowspan="2">Total Carrying Value at December 31, 2014</td><td colspan="4">Fair Value Measurements at December 31, 2014 Using</td></tr><tr><td>Quoted prices in active markets (Level 1)</td><td>Significant other observable inputs (Level 2)</td><td>Significant unobservable inputs (Level 3)</td><td></td></tr><tr><td>Description</td><td></td><td></td><td></td><td></td><td></td></tr><tr><td>Money Market Funds(1)</td><td>$ 36,828</td><td>$ —</td><td>$ 36,828</td><td>$ —</td><td></td></tr><tr><td>Time Deposits(1)</td><td>16,204</td><td>—</td><td>16,204</td><td>—</td><td></td></tr><tr><td>Trading Securities</td><td>13,172</td><td>12,428 (2)</td><td>744 (1)</td><td>—</td><td></td></tr><tr><td>Available-for-Sale Securities</td><td>1,457</td><td>1,457 (2)</td><td>—</td><td>—</td><td></td></tr><tr><td>Derivative Liabilities(3)</td><td>2,411</td><td>—</td><td>2,411</td><td>—</td><td></td></tr><tr><td></td><td></td><td></td><td colspan="3">Fair Value Measurements at December 31, 2015 Using</td></tr><tr><td></td><td></td><td></td><td></td><td></td><td></td></tr><tr><td>Description</td><td>Total Carrying Value at December 31, 2015</td><td>Quoted prices in active markets (Level 1)</td><td>Significant other observable inputs (Level 2)</td><td>Significant unobservable inputs (Level 3)</td><td></td></tr><tr><td>Time Deposits(1)</td><td>$ 18,645</td><td>$ —</td><td>$ 18,645</td><td>$ —</td><td></td></tr><tr><td>Trading Securities</td><td>10,371</td><td>9,514 (2)</td><td>857 (1)</td><td>—</td><td></td></tr><tr><td>Available-for-Sale Securities</td><td>624</td><td>624 (2)</td><td>—</td><td>—</td><td></td></tr></table>

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

(2) Available-for-sale securities and certain trading securities are measured at fair value using quoted market prices.

(3) Our derivative liabilities primarily relate to short-term (six months or less) foreign currency contracts that we have entered into to hedge certain of our intercompany exposures, as more fully disclosed at Note 3. We calculate the fair value of such forward contracts by adjusting the spot rate utilized at the balance sheet date for translation purposes by an estimate of the forward points observed in active markets.

Disclosures are required in the financial statements for items measured at fair value on a non-recurring basis. We did not have any material items that are measured at fair value on a non-recurring basis for the years ended December 31, 2013, 2014 and 2015, except goodwill calculated based on Level 3 inputs, as more fully disclosed in Note 2.g and the assets and liabilities associated with acquisitions, as more fully disclosed in Note 6.

The fair value of our long-term debt, which was determined based on either Level 1 inputs or Level 3 inputs, is disclosed in Note 4. Long-term debt is measured at cost in our Consolidated Balance Sheets as of December 31, 2014 and 2015.

## t. Trading and Available-for-Sale Securities

As of December 31, 2014 and 2015, we have one trust that holds marketable securities. As of December 31, 2014 and 2015, the fair value of the money market and mutual funds included in this trust amounted to $13,172 and $10,371, respectively, and were included in prepaid expenses and other in the accompanying Consolidated Balance Sheets. We classified these marketable securities included in the trust as trading, and included in other expense (income), net in the accompanying Consolidated Statements of Operations are realized and unrealized net gains (losses) of $2,283, $1,112 and $56 for the years ended December 31, 2013, 2014 and 2015, respectively, related to these marketable securities.

As of December 31, 2014 and 2015, we had an investment in Crossroads Systems, Inc. ("Crossroads"). Our investment in Crossroads represented approximately 4% and 2% of the total shares outstanding of Crossroads as of December 31, 2014 and 2015, respectively. The carrying value of our investment in Crossroads as of December 31, 2014 and 2015 was $1,457 and $624, respectively, and is included in other assets in the accompanying Consolidated Balance Sheets. This investment, which is publicly traded, is classified as available-for-sale and is carried at fair value with corresponding changes to fair value recorded in accumulated other comprehensive items, net.

## w. New Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers (Topic 606) ("ASU 2014-09"). ASU 2014-09 provides additional 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. Further disclosures will be required to provide a better understanding of revenue that has been recognized and revenue that is expected to be recognized in the future from existing contracts. 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 defers 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 are currently evaluating the impact ASU 2014-09 will have on our consolidated financial statements.

In August 2014, the FASB issued ASU No. 2014-15, Presentation of Financial Statements Going Concern (Subtopic 205-40) (“ASU 2014-15”). ASU 2014-15 requires management to assess an entity’s ability to continue as a going concern by incorporating and expanding upon certain principles of current United States auditing standards. Specifically, the amendments (1) provide a definition of the term “substantial doubt”, (2) require an evaluation every reporting period, including interim periods, (3) provide principles for considering the mitigating effect of management’s plans, (4) require certain disclosures when substantial doubt is alleviated as a result of consideration of management’s plans, (5) require an express statement and other disclosures when substantial doubt is still present, and (6) require an assessment for a period of one year after the date that the financial statements are issued (or available to be issued). ASU 2014-15 is effective for us on January 1, 2017, with early adoption permitted. We do not believe that the adoption of ASU 2014-15 will have an impact on our consolidated financial statements.

In February 2015, the FASB issued ASU No. 2015-02, Consolidation (Topic 810): Amendments to the Consolidation Analysis (“ASU 2015-02”). ASU 2015-02 affects reporting entities that are required to evaluate whether they should consolidate certain legal entities. ASU 2015-02 is effective for us on January 1, 2016. We do not believe that the adoption of ASU 2015-02 will have an impact on our consolidated financial statements.

## 2. Summary of Significant Accounting Policies (Continued)

In April 2015, the FASB issued ASU No. 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by ASU 2015-03. We adopted ASU 2015-03 during the fourth quarter of 2015. The adoption of ASU 2015-03 did not materially impact our consolidated financial statements.

In September 2015, the FASB issued ASU No. 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments (“ASU 2015-16”). ASU 2015-16 requires that the cumulative impact of a measurement period adjustment (including the impact on prior periods) be recognized in the reporting period in which the adjustment is identified, with the prior period impact of the adjustment being disclosed within the consolidated financial statements. We adopted ASU 2015-16 during the third quarter of 2015. The adoption of ASU 2015-16 did not materially impact our consolidated financial statements.

In November 2015, the FASB issued ASU No. 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes ("ASU 2015-17"). ASU No. 2015-17 eliminates the requirement for reporting entities to present deferred tax liabilities and assets as current and noncurrent in a classified balance sheet. Instead, reporting entities will be required to classify all deferred tax assets and liabilities as noncurrent. ASU 2015-17 is effective for us on January 1, 2017, with early adoption permitted. The amendments in ASU 2015-17 may be applied either prospectively to all deferred tax liabilities and assets or retrospectively to all periods presented. The adoption of ASU 2015-17 will require the reclassification of certain deferred tax assets to noncurrent in our consolidated financial statements.

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. The pronouncement 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 do not believe that the adoption of ASU 2016-01 will have a material impact on our consolidated financial statements.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) ("ASU 2016-02"). ASU 2016-02 will be effective for us on January 1, 2019, with early adoption permitted. We are currently in the process of assessing the impact of ASU 2016-02 on our consolidated financial statements.

## 3. Derivative Instruments and Hedging Activities

We have entered into a number of separate forward contracts to hedge our exposures in Euros, British pounds sterling and Australian dollars. As of December 31, 2014, we had outstanding forward contracts to purchase 206,000 Euros and sell $252,745 United States dollars to hedge our intercompany exposures with our European operations. As of December 31, 2015, we had no forward contracts outstanding. We may in the future enter into forward contracts, and 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 the forward contract and recognize this amount in other expense (income), net in the Consolidated Statements of Operations as a realized foreign exchange gain or loss. At the end of each month, we mark the outstanding forward contracts to market and record an unrealized foreign exchange gain or loss for the mark-to-market valuation. We have not designated any of the forward contracts we have entered into as hedges.

Net cash (receipts) payments included in cash from operating activities related to settlements associated with foreign currency forward contracts for the years ended December 31, 2013, 2014 and 2015, are as follows:

<table><tr><td rowspan="3">Net (receipts) payments</td><td colspan="4">Year Ended December 31,</td></tr><tr><td>2013</td><td>2014</td><td>2015</td><td></td></tr><tr><td>$ (6,954)</td><td>$ 21,125</td><td>$ 22,705</td><td></td></tr></table>

## 3. Derivative Instruments and Hedging Activities (Continued)

Our policy is to record the fair value of each derivative instrument on a gross basis. The following table provides the fair value of our derivative instruments as of December 31, 2014 and 2015 and their gains and losses for the years ended December 31, 2013, 2014 and 2015:

<table><tr><td rowspan="3"></td><td colspan="4">Liability Derivatives</td></tr><tr><td colspan="4">December 31,</td></tr><tr><td colspan="2">2014</td><td colspan="2">2015</td></tr><tr><td>Derivatives Not Designated as Hedging Instruments</td><td>Balance Sheet Location</td><td>Fair Value</td><td>Balance Sheet Location</td><td>Fair Value</td></tr><tr><td>Foreign exchange contracts</td><td>Accrued expenses</td><td>$2,411</td><td>Accrued expenses</td><td>$—</td></tr><tr><td>Total</td><td></td><td>$2,411</td><td></td><td>$—</td></tr><tr><td></td><td></td><td></td><td></td><td></td></tr></table>

We have designated a portion of our previously outstanding  $ 6^{3}/_{4}\% \)  Notes and Euro denominated borrowings by IMI under our Revolving Credit Facility (discussed more fully in Note 4) as a hedge of net investment of certain of our Euro denominated subsidiaries. For the years ended December 31, 2013, 2014 and 2015, we designated on average 106,525, 47,730 and 34,331 Euros, respectively, of the previously outstanding  $ 6^{3}/_{4}\% \)  Notes and Euro denominated borrowings by IMI under our Revolving Credit Facility as a hedge of net investment of certain of our Euro denominated subsidiaries. As a result, we recorded the following foreign exchange (losses) gains, net of tax, related to the change in fair value of such debt due to the currency translation adjustments, which is a component of accumulated other comprehensive items, net:

<table><tr><td rowspan="2"></td><td colspan="4">Year Ended December 31,</td></tr><tr><td>2013</td><td>2014</td><td>2015</td><td></td></tr><tr><td>Foreign exchange (losses) gains</td><td>$ (5,311)</td><td>$ 6,385</td><td>$ 3,284</td><td></td></tr><tr><td>Less: Tax benefit (expense) on foreign exchange (losses) gains</td><td>2,073</td><td>(57)</td><td>—</td><td></td></tr><tr><td>Foreign exchange (losses) gains, net of tax</td><td>$ (3,238)</td><td>$ 6,328</td><td>$ 3,284</td><td></td></tr></table>

As of December 31, 2015, cumulative net gains of $17,096, net of tax are recorded in accumulated other comprehensive items, net associated with this net investment hedge.

## 4. Debt (Continued)

(1) The capital stock or other equity interests of most of our United States subsidiaries, and up to 66% of the capital stock or other equity interests of our first-tier foreign subsidiaries, are pledged to secure these debt instruments, together with all intercompany obligations (including promissory notes) of subsidiaries owed to us or to one of our United States subsidiary guarantors. In addition, Iron Mountain Canada Operations ULC ("Canada Company") has pledged 66% of the capital stock of its subsidiaries, and all intercompany obligations (including promissory notes) owed to or held by it, to secure the Canadian dollar subfacility under both the Former Revolving Credit Facility and the Revolving Credit Facility (each of which is defined below). The fair value (Level 3 of fair value hierarchy described at Note 2.s) of these debt instruments approximates the carrying value (as borrowings under these debt instruments are based on current variable market interest rates (plus a margin that is subject to change based on our consolidated leverage ratio)), as of both December 31, 2014 and 2015.

(2) The fair values (Level 1 of fair value hierarchy described at Note 2.s.) of these debt instruments are based on quoted market prices for these notes on December 31, 2014 and 2015, respectively.

(3) Collectively, the "Parent Notes." IMI is the direct obligor on the Parent Notes, which are fully and unconditionally guaranteed, on a senior or senior subordinated basis, as the case may be, by its direct and indirect 100% owned United States subsidiaries that represent the substantial majority of our United States operations (the "Guarantors"). These guarantees are joint and several obligations of the Guarantors. Canada Company, Iron Mountain Europe PLC ("IME") and the remainder of our subsidiaries do not guarantee the Parent Notes. See Note 5 to Notes to Consolidated Financial Statements.

(4) As of December 31, 2014, the amount of debt for the 6 \( ^{3} \) / \( _{4} \) % Notes and the 8 \( ^{3} \) / \( _{8} \) % Notes reflect an unamortized original issue discount of 1,018 and 220, respectively.

(5) Canada Company is the direct obligor on the CAD Notes, which are fully and unconditionally guaranteed, on a senior basis, by IMI and the Guarantors. These guarantees are joint and several obligations of IMI and the Guarantors. See Note 5 to Notes to Consolidated Financial Statements.

(6) The 6% Notes due 2020 and the GBP Notes have not been registered under the Securities Act of 1933, as amended (the “Securities Act”), or under the securities laws of any other jurisdiction. Unless they are registered, the 6% Notes due 2020 and the GBP Notes may be offered only in transactions that are exempt from registration under the Securities Act or the securities laws of any other jurisdiction.

(7) IME is the direct obligor on the GBP Notes, which are fully and unconditionally guaranteed, on a senior basis, by IMI and the Guarantors. These guarantees are joint and several obligations of IMI and the Guarantors. See Note 5 to Notes to Consolidated Financial Statements.

(8) Includes (a) real estate mortgages of $5,107 and $2,713 as of December 31, 2014 and 2015, respectively, which bear interest at approximately 4.9% and are payable in various installments through 2021, (b) capital lease obligations of $241,866 and $235,348 as of December 31, 2014 and 2015, respectively, which bear a weighted average interest rate of 5.8% at December 31, 2014 and 7.2% at December 31, 2015, and (c) other notes and other obligations, which were assumed by us as a result of certain acquisitions, of $73,729 and $95,498 as of December 31, 2014 and 2015, respectively, and bear a weighted average interest rate of 11.5% and 12.6% as of December 31, 2014 and 2015, respectively. We believe the fair value (Level 3 of fair value hierarchy described at Note 2.s.) of this debt approximates its carrying value.

(9) The Special Purpose Subsidiaries are the obligors under this program. We believe the fair value (Level 3 of fair value hierarchy described at Note 2.s.) of this debt approximates its carrying value.

## 4. Debt (Continued)

## a. Credit Agreement

On July 2, 2015, we entered into a new credit agreement (the "Credit Agreement") to refinance 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 June 27, 2016. The Credit Agreement consists of a revolving credit facility (the "Revolving Credit Facility") and a term loan (the "Term Loan").

The Revolving Credit Facility is supported by a group of 25 banks and 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, Euros and Australian dollars, among other currencies) in an aggregate outstanding amount not to exceed $1,500,000. The Term Loan is to be paid in quarterly installments in an amount equal to $3,125 per quarter, with the remaining balance due on July 3, 2019. The Credit Agreement includes an option to allow us 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 as defined in the Credit Agreement. The Credit Agreement terminates on July 6, 2019, at which point all obligations become due, but may be extended by one year at our option, subject to the conditions set forth in the Credit Agreement. Borrowings under the Credit Agreement may be prepaid without penalty or premium, in whole or in part, at any time.

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, 2015, we had $784,438 and $243,750 of outstanding borrowings under the Revolving Credit Facility and the Term Loan, respectively. Of the $784,438 of outstanding borrowings under the Revolving Credit Facility, $480,400 was denominated in United States dollars, 190,000 was denominated in Canadian dollars, 105,250 was denominated in Euros and 71,600 was denominated in Australian dollars. In addition, we also had various outstanding letters of credit totaling $36,624. The remaining amount available for borrowing under the Revolving Credit Facility as of December 31, 2015, based on IMI's leverage ratio, the last 12 months' earnings before interest, taxes, depreciation and amortization and rent expense ("EBITDAR"), other adjustments as defined in the Credit Agreement and current external debt, was $678,938 (which amount represents the maximum availability as of such date). The average interest rate in effect under the Credit Agreement was 2.7% as of December 31, 2015. The average interest rate in effect under the Revolving Credit Facility was 2.8% and ranged from 2.3% to 4.8% as of December 31, 2015 and the interest rate in effect under the Term Loan as of December 31, 2015 was 2.5%.

We recorded a charge of $2,156 to other expense (income), net in the third quarter of 2015 related to the refinancing of the Former Credit Agreement, representing a write-off of unamortized deferred financing costs. We recorded a charge of $5,544 to other expense (income), net in the third quarter of 2013 related to the Former Credit Agreement, representing a write-off of deferred financing costs.

The Credit Agreement, our indentures and other agreements governing our indebtedness contain certain restrictive financial and operating covenants, including covenants that restrict our ability to complete acquisitions, pay cash dividends, incur indebtedness, make investments, sell assets and take certain other corporate actions. The covenants do not contain a rating trigger. Therefore, a change in our debt rating would not trigger a default under the Credit Agreement, our indentures or other agreements governing our indebtedness. The Credit Agreement uses EBITDA-based calculations as the primary measures of financial performance, including leverage and fixed charge coverage ratios.

(In thousands, except share and per share data)

## 4. Debt (Continued)

Our leverage and fixed charge coverage ratios under both the Former Credit Agreement and the Credit Agreement as of December 31, 2014 and 2015, respectively, and our leverage ratio under our indentures as of December 31, 2014 and 2015 are as follows:

<table><tr><td></td><td>December 31, 2014</td><td>December 31, 2015</td><td>Maximum/Minimum Allowable(1)</td></tr><tr><td>Net total lease adjusted leverage ratio</td><td>5.4</td><td>5.6</td><td>Maximum allowable of 6.5</td></tr><tr><td>Net secured debt lease adjusted leverage ratio</td><td>2.6</td><td>2.6</td><td>Maximum allowable of 4.0</td></tr><tr><td>Bond leverage ratio (not lease adjusted)</td><td>5.7</td><td>5.5</td><td>Maximum allowable of 6.5</td></tr><tr><td>Fixed charge coverage ratio</td><td>2.5</td><td>2.4</td><td>Minimum allowable of 1.5</td></tr></table>

(1) The maximum and minimum allowable ratios under the Credit Agreement are substantially similar to the Former Credit Agreement.

As noted in the table above, our maximum allowable net total lease adjusted leverage ratio under the Credit Agreement is 6.5. The Credit Agreement also contains a provision which limits, in certain circumstances, our dividends in any four consecutive fiscal quarters to 95% of Funds From Operations (as defined in the 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 limitation only is applicable when our net total lease adjusted leverage ratio exceeds 6.0.

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, 2013, 2014 and 2015, are as follows:

<table><tr><td rowspan="2"></td><td colspan="4">Year Ended December 31,</td></tr><tr><td>2013</td><td>2014</td><td>2015</td><td></td></tr><tr><td>Commitment fees and letters of credit fees</td><td>$ 3,167</td><td>$ 3,322</td><td>$ 3,743</td><td></td></tr></table>

## b. Notes Issued under Indentures

As of December 31, 2015, we had five series of senior subordinated or senior notes issued under various indentures, three of which are direct obligations of the parent company, IMI; one (the CAD Notes) is a direct obligation of Canada Company; one (the GBP Notes) is a direct obligation of IME; and all are pari passu with debt outstanding under the Credit Agreement, except the  $ 5^{3}/_{4}\% \)  Notes which are subordinated to the Credit Agreement:

- $1,000,000 principal amount of senior notes maturing on October 1, 2020 and bearing interest at a rate of 6% per annum, payable semi-annually in arrears on April 1 and October 1;

- 200,000 CAD principal amount of senior notes maturing on August 15, 2021 and bearing interest at a rate of  $ 6^{1}/_{8}\% \)  per annum, payable semi-annually in arrears on February 15 and August 15;

- 400,000 British pounds sterling principal amount of senior notes maturing on September 15, 2022 and bearing interest at a rate of  $ 6^{1}/_{8}\% \)  per annum, payable semi-annually in arrears on March 15 and September 15;

- $600,000 principal amount of senior notes maturing on August 15, 2023 and bearing interest at a rate of 6% per annum, payable semi-annually in arrears on February 15 and August 15; and

- $1,000,000 principal amount of senior subordinated notes maturing on August 15, 2024 and bearing interest at a rate of  $ 5^{3}/_{4}\% \)  per annum, payable semi-annually in arrears on February 15 and August 15.

## 4. Debt (Continued)

The Parent Notes, the CAD Notes and the GBP Notes are fully and unconditionally guaranteed, on a senior or senior subordinated basis, as the case may be, by the Guarantors. These guarantees are joint and several obligations of the Guarantors. The remainder of our subsidiaries do not guarantee the Parent Notes, the CAD Notes or the GBP Notes. Additionally, IMI guarantees the CAD Notes and the GBP Notes. Canada Company and IME do not guarantee the Parent Notes.

In August 2013, IMI completed an underwritten public offering of $600,000 in aggregate principal amount of the 6% Notes due 2023, and Canada Company completed an underwritten public offering of 200,000 CAD in aggregate principal amount of the CAD Notes, both of which were issued at 100% of par (together, the "August 2013 Offerings"). The net proceeds to IMI and Canada Company of $782,307, after paying the underwriters' discounts and commissions, were used to redeem (1) all of the outstanding 7 \( ^{1}/_{2} \) % CAD Senior Subordinated Notes due 2017, (2) all of the outstanding 8% Senior Subordinated Notes due 2018, (3) all of the outstanding 8% Senior Subordinated Notes due 2020, and (4) $137,500 in principal amount of the 8 \( ^{3}/_{8} \) % Notes. The remaining net proceeds were used to repay indebtedness under the Former Revolving Credit Facility. We recorded a charge to other expense (income), net of $38,118 in the third quarter of 2013 related to the early extinguishment of this debt. This charge consists of call and tender premiums, original issue discounts and unamortized deferred financing costs.

In January 2014, we redeemed the 150,000 British pounds sterling (approximately $248,000) in aggregate principal amount of the 7 \( ^{1}/_{4} \) % Notes at 100% of par, plus accrued and unpaid interest, utilizing borrowings under the Former Revolving Credit Facility and cash on-hand.

In September 2014, IME completed a private offering of 400,000 British pounds sterling in aggregate principal amount of the GBP Notes, which were issued at 100% of par. The net proceeds to IME of 394,000 British pounds sterling (approximately $642,000 based on an exchange rate of 1.63), after paying the initial purchasers' commissions and expenses, were used to repay amounts outstanding under the Former Revolving Credit Facility and for general corporate purposes.

In December 2014, we redeemed $306,000 aggregate principal outstanding of our 8 \( ^{3}/_{8} \) % Notes at 104.188% of par, plus accrued and unpaid interest, utilizing borrowings under the Former Revolving Credit Facility. We recorded a charge to other expense (income), net of $16,495 related to the early extinguishment of this debt in the fourth quarter of 2014 representing the call premium associated with the early redemption, as well as a write-off of original issue discounts and unamortized deferred financing costs.

In September 2015, IMI completed a private offering of $1,000,000 in aggregate principal amount of the 6% Notes due 2020. The net proceeds to IMI of $985,000, after paying the initial purchasers' commissions and expenses, were used to redeem all of the 6 \( ^{3}/_{4} \) % Notes, 7 \( ^{3}/_{4} \) % Notes and 8 \( ^{3}/_{8} \) % Notes in October 2015. The remaining net proceeds were used for general corporate purposes, including acquisitions. We recorded a charge to other expense (income), net of $25,112 in the fourth quarter of 2015 related to the early extinguishment of this debt. This charge consists of call premiums, original issue discounts and unamortized deferred financing costs.

Each of the indentures for the notes provides that we may redeem the outstanding notes, in whole or in part, upon satisfaction of certain terms and conditions. In any redemption, we are also required to pay all accrued but unpaid interest on the outstanding notes.

## c. Accounts Receivable Securitization Program

In March 2015, we entered into a $250,000 accounts receivable securitization program (the "Accounts Receivable Securitization Program") involving several of our wholly owned subsidiaries and certain financial institutions. Under the Accounts Receivable Securitization Program, certain of our subsidiaries sell substantially all of their United States accounts receivable balances to our wholly owned special purpose entities, Iron Mountain Receivables QRS, LLC and Iron Mountain Receivables TRS, LLC (the "Special Purpose Subsidiaries"). The Special Purpose Subsidiaries use the accounts receivable balances to collateralize loans obtained from certain financial institutions. The 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 Sheet, (ii) our Consolidated Statement of Operations reflects 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 Statement of Cash Flows. Iron Mountain Information Management, LLC retains the responsibility of servicing the accounts receivable balances pledged as collateral in this transaction and IMI provides a performance guaranty. The Accounts Receivable Securitization Program terminates on March 6, 2018, at which point all obligations become due. 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, 2015, the maximum availability allowed and amount outstanding under the Accounts Receivable Securitization Program was $205,900. The interest rate in effect under the Accounts Receivable Securitization Program was 1.3% as of December 31, 2015. Commitment fees at a rate of 40 basis points are charged on amounts made available but not borrowed under the Accounts Receivable Securitization Program.

Maturities of long-term debt are as follows:

<table><tr><td>Year</td><td>Amount</td></tr><tr><td>2016</td><td>$ 88,068</td></tr><tr><td>2017</td><td>98,093</td></tr><tr><td>2018</td><td>260,847</td></tr><tr><td>2019</td><td>1,015,626</td></tr><tr><td>2020</td><td>1,017,774</td></tr><tr><td>Thereafter</td><td>2,423,569</td></tr><tr><td></td><td>4,903,977</td></tr><tr><td>Net Deferred Financing Costs</td><td>(58,299)</td></tr><tr><td>Total Long-term Debt (including current portion)</td><td>$ 4,845,678</td></tr></table>

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

The following data summarizes the consolidating results of IMI on the equity method of accounting as of December 31, 2014 and 2015 and for the years ended December 31, 2013, 2014 and 2015 and are prepared on the same basis as the consolidated financial statements.

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

Additionally, IMI guarantees the CAD Notes, which were issued by Canada Company, and the GBP Notes, which were issued by IME. Canada Company and IME do not guarantee the Parent Notes. The subsidiaries that do not guarantee the Parent Notes, the CAD Notes and the GBP Notes, including IME and the Special Purpose Subsidiaries but excluding Canada Company, are referred to below as the Non-Guarantors.

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 with respect to the relevant Parent, Guarantors, Canada Company, Non-Guarantors and Eliminations columns also would change.

In March 2015, we entered into the Accounts Receivable Securitization Program, which is described more fully in Note 4. The Special Purpose Subsidiaries, which were established in conjunction with the Accounts Receivable Securitization Program, are included in the Non-Guarantors column in the below Consolidated Balance Sheet, Consolidated Statement of Operations and Consolidated Statement of Cash Flows from that date forward. As a result of the Accounts Receivable Securitization Program, certain of our Guarantors sold substantially all of their United States accounts receivable balances to the Special Purpose Subsidiaries. As of December 31, 2015, this resulted in a decrease in accounts receivable, an increase in intercompany receivable and a decrease in long-term debt related to our Guarantors and a corresponding increase in accounts receivable, an increase in intercompany payable and an increase in long-term debt related to our Non-Guarantors. There was no material impact to the Guarantors and Non-Guarantors columns of the below Consolidated Statements of Operations for the year ended December 31, 2015 as a result of the Accounts Receivable Securitization Program. Additionally, the Accounts Receivable Securitization Program resulted in increased financing cash flow activity for the Non-Guarantors for the year ended December 31, 2015, as the proceeds from borrowings under the Accounts Receivable Securitization Program were used to repay intercompany loans with certain of the Guarantors, which resulted in increased cash flows from investing activities for the Guarantors for the year ended December 31, 2015.

## 6. Acquisitions

We account for acquisitions using the acquisition method of accounting, and, accordingly, the assets and liabilities acquired were 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. Cash consideration for our various acquisitions was primarily provided through borrowings under our credit facilities and cash equivalents on-hand. The unaudited pro forma results of operations (including revenue and earnings) for the current and prior periods are not presented due to the insignificant impact of the 2013, 2014 and 2015 acquisitions on our consolidated results of operations. Noteworthy acquisitions are as follows:

In May 2013, in order to enhance our existing operations in the United States, we acquired a storage rental and records management business in Texas with locations in Michigan, Texas and Florida, in a cash transaction for a purchase price of approximately $25,000.

In June 2013, in order to enhance our existing operations in Brazil, we acquired the stock of Archivum Comercial Ltda. and AMG Comercial Ltda., storage rental and records management businesses in Sao Paulo, Brazil, in a single transaction for an aggregate purchase price of approximately $29,000.

## 6. Acquisitions (Continued)

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.

A summary of the cumulative consideration paid and the allocation of the purchase price paid of all of the acquisitions in each respective year is as follows:

<table><tr><td></td><td>2013</td><td>2014</td><td>2015</td></tr><tr><td>Cash Paid (gross of cash acquired)(1)</td><td>$ 321,121</td><td>$ 134,301</td><td>$ 111,907</td></tr><tr><td>Fair Value of Previously Held Equity Interest</td><td>—</td><td>794</td><td>—</td></tr><tr><td>Total Consideration</td><td>321,121</td><td>135,095</td><td>111,907</td></tr><tr><td>Fair Value of Identifiable Assets Acquired:</td><td></td><td></td><td></td></tr><tr><td>Cash, Accounts Receivable, Prepaid Expenses,</td><td></td><td></td><td></td></tr><tr><td>Deferred Income Taxes and Other</td><td>28,532</td><td>15,098</td><td>12,670</td></tr><tr><td>Property, Plant and Equipment(2)</td><td>44,681</td><td>23,269</td><td>43,505</td></tr><tr><td>Customer Relationship Intangible Assets(3)</td><td>173,733</td><td>60,172</td><td>34,988</td></tr><tr><td>Other Assets</td><td>68</td><td>3,342</td><td>7,032</td></tr><tr><td>Liabilities Assumed and Deferred Income Taxes(4)</td><td>(67,645)</td><td>(50,903)</td><td>(26,807)</td></tr><tr><td>Total Fair Value of Identifiable Net Assets Acquired</td><td>179,369</td><td>50,978</td><td>71,388</td></tr><tr><td>Goodwill Initially Recorded</td><td>$ 141,752</td><td>$ 84,117</td><td>$ 40,519</td></tr></table>

(1) Included in cash paid for acquisitions in the Consolidated Statements of Cash Flows for the year ended December 31, 2013 is net of cash acquired of $(3,945) and contingent and other payments of $(76). Included in cash paid for acquisitions in the Consolidated Statements of Cash Flows for the year ended December 31, 2014 is net cash acquired of $(4,704) and contingent and other payments of $(1,504) related to acquisitions made in previous years. Included in cash paid for acquisitions in the Consolidated Statements of Cash Flows for the year ended December 31, 2015 is net cash acquired of $(2,041) and contingent and other payments of $3,692 related to acquisitions made in previous years.

(2) Consists primarily of buildings, racking structures, leasehold improvements and computer hardware and software.

(3) The weighted average lives of customer relationship intangible assets associated with acquisitions in 2013, 2014 and 2015 was 22 years, 17 years and 16 years, respectively.

(4) Consists primarily of accounts payable, accrued expenses, notes payable, deferred revenue and deferred income taxes.

Allocations of the purchase price paid for certain acquisitions made in 2015 were based on estimates of the fair value of net assets acquired and are subject to adjustment as additional information becomes available to us. We are not aware of any information that would indicate that the final purchase price allocations for these 2015 acquisitions will differ meaningfully from preliminary estimates. The purchase price allocations of these 2015 acquisitions are subject to finalization of the assessment of the fair value of intangible assets (primarily customer relationship intangible assets), property, plant and equipment (primarily buildings and racking structures), operating leases, contingencies and income taxes (primarily deferred income taxes).

## 6. Acquisitions (Continued)

In September 2014, we purchased our joint venture partners' noncontrolling interests in the businesses we operate in Russia, Ukraine and Denmark, which we had previously consolidated. The purchase price of approximately $24,500 is comprised of $17,900 paid at closing, $2,100 payable in 2017 and $4,500 payable in 2020. The components of the purchase price payable in 2017 and 2020 are reflected as non-cash items within our Consolidated Statement of Cash Flows for the year ended December 31, 2014. Of the $17,900 paid at closing, approximately $11,950 was associated with the underlying shares owned by our joint venture partners and approximately $5,950 was associated with the payment of outstanding loans between the joint venture and the joint venture partners.

On June 8, 2015, we entered into a binding Scheme Implementation Deed (the "Recall Agreement") with Recall Holdings Limited ("Recall") to acquire Recall (the "Recall Transaction") by way of a recommended court approved Scheme of Arrangement (the "Scheme"). Under the terms of the Recall Agreement, Recall shareholders are entitled to receive the Australian dollar equivalent of US$0.50 in cash for each outstanding share of Recall common stock (the "Cash Supplement") as well as either (1) 0.1722 shares of our common stock for each Recall share or (2) 8.50 Australian dollars less the Australian dollar equivalent of US$0.50 in cash for each Recall share (the "Cash Election"). The Cash Election is subject to a proration mechanism that will cap the total amount of cash paid to Recall shareholders electing the Cash Election at 225,000 Australian dollars (the "Cash Election Cap"). Amounts paid to Recall shareholders that represent the Cash Supplement are excluded from the calculation of the Cash Election Cap. Assuming a sufficient number of Recall shareholders elect the Cash Election such that we pay the Cash Election Cap, we expect to issue approximately 50,700,000 shares of our common stock and, based on the exchange rate between the United States dollar and the Australian dollar as of February 19, 2016, pay approximately US $323,000 to Recall shareholders in connection with the Recall Transaction which, based on the closing price of our common stock as of February 19, 2016, would result in a total purchase price to Recall shareholders of approximately $1,791,000. Completion of the Scheme is subject to customary closing conditions, including among others, (i) approval by Recall shareholders of the Scheme by the requisite majority under the Australian Corporations Act, (ii) expiration or earlier termination of any applicable waiting period and receipt of regulatory consents, approvals and clearances, in each case, under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and under relevant antitrust/competition and foreign investment legislation in other relevant jurisdictions, (iii) the absence of any final, non-appealable order, decree or law preventing, making illegal or prohibiting the completion of the Recall Transaction, (iv) approval from the New York Stock Exchange to the listing of additional shares of our common stock to be issued in the Recall Transaction, (v) the establishment of a secondary listing on the Australian Securities Exchange (the "ASX") to allow Recall shareholders to trade our common stock via CHESS Depository Interests on the ASX, (vi) Recall's delivery of tax opinions in accordance and in compliance with certain tax matter agreements to which Recall is a party and (vii) no events having occurred that would have a material adverse effect on Recall or us. We continue to work toward closing of the Recall Transaction and related integration planning.

## 7. Income Taxes

We have been organized and operating as a REIT effective since our taxable year that began on January 1, 2014. As a REIT, we are generally permitted to deduct from our federal taxable income the dividends we pay to our stockholders. The income represented by such dividends is not subject to federal taxation at the entity level but is taxed, if at all, at the stockholder level. The income of our domestic taxable REIT subsidiaries ("TRSs"), which hold our domestic operations that may not be REIT-compliant as currently operated and structured, is subject, as applicable, to federal and state corporate income tax. In addition, we and our subsidiaries continue to be subject to foreign income taxes in jurisdictions in which we have business operations or a taxable presence, regardless of whether assets are held or operations are conducted through subsidiaries disregarded for federal tax purposes or TRSs. We will also be subject to a separate corporate income tax on any gains recognized during a five-year period following the REIT conversion that are attributable to "built-in" gains with respect to the assets that we owned on January 1, 2014. This built-in gains tax has been imposed on our depreciation recapture recognized into income as a result of accounting method changes commenced in our pre-REIT period. If we fail to remain qualified for taxation as a REIT, we will be subject to federal income tax at regular corporate 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.

The significant components of the deferred tax assets and deferred tax liabilities are presented below:

We have federal net operating loss carryforwards, which expire in 2021 through 2033, of $70,820 at December 31, 2015 to reduce future federal taxable income, on which $3,022 of federal tax benefit is expected to be realized. We can carry forward these net operating losses to the extent we do not utilize them in any given available year. We have state net operating loss carryforwards, which expire from 2016 through 2034, on which an insignificant state tax benefit is expected to be realized. We have assets for foreign net operating losses of $66,155, with various expiration dates (and in some cases no expiration date), subject to a valuation allowance of approximately 91%.

Rollforward of the valuation allowance is as follows:

We receive a tax deduction upon the exercise of non-qualified stock options or upon the disqualifying disposition by employees of incentive stock options and certain shares acquired under our ESPP for the difference between the exercise price and the market price of the underlying common stock on the date of exercise or disqualifying disposition. The tax benefit for non-qualified stock options associated with our TRSs is included in the consolidated financial statements in the period in which compensation expense is recorded. The tax benefit associated with compensation expense recorded in the consolidated financial statements related to incentive stock options associated with our TRSs is recorded in the period the disqualifying disposition occurs. Incremental tax benefits (deficiencies) in excess of compensation expense recorded in the consolidated financial statements are credited (charged) directly to equity and amounted to $2,389, $ (60) and $327 for the years ended December 31, 2013, 2014 and 2015, respectively.

## 7. Income Taxes (Continued)

Our effective tax rates for the years ended December 31, 2013, 2014 and 2015 were 38.9%, (43.5%) and 23.3%, respectively. Our effective tax rate is subject to variability in the future due to, among other items: (1) changes in the mix of income between our qualified REIT subsidiaries and our TRSs, as well as between 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.

During 2013, we completed a plan to utilize both current and carryforward foreign tax credits by repatriating approximately $252,700 (approximately $65,200 of which was previously subject to United States taxes) from our foreign earnings. Due to uncertainty in our ability to fully utilize foreign tax credit carryforwards, we previously did not recognize a full benefit for such foreign tax credit carryforwards in our tax provision. As a result, we recorded an increase in our tax provision from continuing operations in the amount of $63,504 in 2013. This increase was offset by decreases of $18,753 from current year foreign tax credits and $23,301 reversal of valuation allowances related to foreign tax credit carryforwards, resulting in a net increase of $21,450 in our tax provision from continuing operations.

As a result of our REIT conversion, we recorded a net tax benefit of $212,151 during the year ended December 31, 2014 for the revaluation of certain deferred tax assets and liabilities associated with the REIT conversion. In 2014, we recorded an increase to the tax provision of $29,298 associated with tax accounting method changes consistent with our REIT conversion, primarily affected through the filing of amended tax returns. The other primary reconciling items between the federal statutory rate of 35% and our overall effective tax rate during the year ended December 31, 2014 was an increase of $46,356 in our tax provision associated with incremental federal and state income taxes and foreign withholding taxes on earnings of our foreign subsidiaries no longer considered permanently invested and other net tax adjustments related to the REIT conversion, including a tax benefit of $63,333 primarily related to the dividends paid deduction.

The primary reconciling items between the federal statutory rate of 35% 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.

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.

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 at the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement.

We have elected to recognize interest and penalties associated with uncertain tax positions as a component of the provision (benefit) for income taxes in the accompanying Consolidated Statements of Operations. We recorded an increase of $1,459, $1,462 and $2,173 for gross interest and penalties for the years ended December 31, 2013, 2014 and 2015, respectively. We had $5,884 and $7,120 accrued for the payment of interest and penalties as of December 31, 2014 and 2015, respectively.

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

<table><tr><td>Tax Years</td><td>Tax Jurisdiction</td></tr><tr><td>See Below</td><td>United States—Federal and State</td></tr><tr><td>2006 to present</td><td>Canada</td></tr><tr><td>2010 to present</td><td>United Kingdom</td></tr></table>

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 2012, 2013 and 2014 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 2000, 2001, 2008 and 2009 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, 2014, we had $55,951 of reserves related to uncertain tax positions, of which $53,078 and $2,873 is included in other long-term liabilities and deferred income taxes, respectively, in the accompanying Consolidated Balance Sheet. As of December 31, 2015, we had $47,685 of reserves related to uncertain tax positions, of which $45,256 and $2,429 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.

The reversal of these reserves of $47,685 ($36,062 net of federal tax benefit) as of December 31, 2015 will be recorded as a reduction of our income tax provision if sustained. We believe that it is reasonably possible that an amount up to approximately $2,730 of our unrecognized tax positions may be recognized by the end of 2016 as a result of a lapse of statute of limitations or upon closing and settling significant audits in various worldwide jurisdictions.

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

(1) The change in net income (loss) attributable to Iron Mountain Incorporated in the fourth quarter of 2014 compared to the third quarter of 2014 is primarily attributable to a decrease in the provision for income taxes recorded in the fourth quarter of 2014 compared to the third quarter of 2014 of approximately $54,000. The decrease in the income tax provision was offset by a decrease in operating income of approximately $13,600, a debt extinguishment charge recorded in the fourth quarter of 2014 of approximately $16,500 and an increase in interest expense of $9,800. The decrease in operating income is attributable to a $8,300 increase in selling, general and administrative expenses, primarily due to higher professional fees and charitable contributions, as well as a $4,700 decrease in revenue, primarily due to unfavorable changes in foreign exchange rates, in the fourth quarter compared to the third quarter.

(2) The change in net income (loss) attributable to Iron Mountain Incorporated in the fourth quarter of 2015 compared to the third quarter of 2015 is primarily attributable to a debt extinguishment charge recorded in the fourth quarter of 2015 of approximately $25,100, an increase in the provision for income taxes recorded in the fourth quarter of 2015 compared to the third quarter of 2015 of approximately $6,800, as well as a decrease in operating income of approximately $3,600, primarily associated with a $1,800 write-off of certain property in our Western European Business segment. The debt extinguishment charge, the increase in the provision for income taxes and the decrease in operating income during the fourth quarter of 2015 was offset by a decrease in loss on foreign currency transaction losses recorded in the fourth quarter of 2015 compared to the third quarter of 2015 of approximately $18,100.

## 9. Segment Information

As a result of a realignment in our senior management reporting structure during the first quarter of 2015, we modified our internal financial reporting to better align internal reporting with how we manage our business. These modifications resulted in the separation of our former International Business segment into two unique reportable operating segments, which we refer to as (1) Western European Business segment and (2) Other International Business segment. Also, during the first quarter of 2015, we reassessed the nature of certain costs which were previously being allocated to the North American Records and Information Management Business and North American Data Management Business segments. As a result of this reassessment, we determined that certain product management functions, which were previously being performed to solely benefit our North American operating segments, are now being performed in a manner that benefits the enterprise as a whole. Accordingly, the costs associated with these product management functions are now included within the Corporate and Other Business segment. Additionally, during the fourth quarter of 2015, as a result of changes in the senior management of our business in Norway, we determined that our Norway operations are now being managed as a component of our Other International Business segment rather than as a component of our Western European Business segment.

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

Our five reportable operating segments are described as follows:

- North American Records and Information Management Business—storage and information management services, including the storage of physical records, including other media such as microfilm and microfiche, master audio and videotapes, film, X-rays and blueprints, including healthcare information services, vital records services, service and courier operations, and the collection, handling and disposal of sensitive documents for corporate customers (“Records Management”); information destruction services (“Destruction”); and DMS throughout the United States and Canada; as well as Fulfillment Services and Intellectual Property Management in the United States.

- North American Data Management Business—storage and rotation of backup computer media as part of corporate disaster recovery plans including service and courier operations (“Data Protection & Recovery”); server and computer backup services; digital content repository systems to house, distribute, and archive key media assets; and storage, safeguarding and electronic or physical delivery of physical media of all types, primarily for entertainment and media industry clients, throughout the United States and Canada.

- Western European Business—storage and information management services, including Records Management, Data Protection & Recovery and DMS throughout the United Kingdom, Ireland, Austria, Belgium, France, Germany, Netherlands, Spain and Switzerland. Until December 2014, our Western European Business segment offered Destruction in the United Kingdom and Ireland.

- Other International Business—storage and information management services throughout the remaining European countries in which we operate, Latin America and Asia Pacific, including Records Management, Data Protection & Recovery and DMS. Our European operations included within the Other International Business segment provide Records Management, Data Protection & Recovery and DMS. Our Latin America operations provide Records Management, Data Protection & Recovery, Destruction and DMS throughout Argentina, Brazil, Chile, Colombia, Mexico and Peru. Our Asia Pacific operations provide Records Management, Data Protection & Recovery and DMS throughout Australia, with Records Management and Data Protection & Recovery also provided in certain cities in India, Singapore, Hong Kong-SAR and China. Until December 2014, our Other International Business segment offered Destruction in Australia.

- Corporate and Other Business—primarily consists of our data center and fine art storage businesses in the United States, the primary product offerings of our Adjacent Businesses operating segment (which was formerly referred to as our Emerging Business operating segment), as well as costs related to executive and staff functions, including finance, human resources and information technology, which benefit the enterprise as a whole. These costs are primarily related to the general management of these functions on a corporate level and the design and development of programs, policies and procedures that are then implemented in the individual segments, with each segment bearing its own cost of implementation. Our Corporate and Other Business segment also includes stock-based employee compensation expense associated with all Employee Stock-Based Awards.

## 9. Segment Information (Continued)

The accounting policies of the reportable segments are the same as those described in Note 2. Adjusted OIBDA for each segment is defined as operating income before depreciation, amortization, intangible impairments, (gain) loss on disposal/writedown of property, plant and equipment, net (excluding real estate), Recall Costs (as defined below) and REIT Costs (as defined below) directly attributable to the segment. Internally, we use Adjusted OIBDA as the basis for evaluating the performance of, and allocating resources to, our operating segments.

A reconciliation of Adjusted OIBDA to income (loss) from continuing operations before provision (benefit) for income taxes and gain on sale of real estate on a consolidated basis is as follows:

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 $244,390, $255,193 and $242,205 for the years ended December 31, 2013, 2014 and 2015, 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:

<table><tr><td>Year</td><td>Operating Lease Payment</td><td>Sublease Income</td><td>Capital Leases</td></tr><tr><td>2016</td><td>$ 220,357</td><td>$ (4,827)</td><td>$ 56,543</td></tr><tr><td>2017</td><td>208,975</td><td>(4,354)</td><td>49,217</td></tr><tr><td>2018</td><td>196,632</td><td>(3,316)</td><td>39,696</td></tr><tr><td>2019</td><td>184,157</td><td>(2,864)</td><td>31,909</td></tr><tr><td>2020</td><td>171,794</td><td>(2,922)</td><td>24,418</td></tr><tr><td>Thereafter</td><td>1,046,705</td><td>(10,327)</td><td>134,532</td></tr><tr><td>Total minimum lease payments</td><td>$ 2,028,620</td><td>$ (28,610)</td><td>336,315</td></tr><tr><td>Less amounts representing interest</td><td></td><td></td><td>(100,967)</td></tr><tr><td>Present value of capital lease obligations</td><td></td><td></td><td>$ 235,348</td></tr></table>

In addition, we have certain contractual obligations related to purchase commitments which require minimum payments as follows:

<table><tr><td>Year</td><td>Purchase Commitments</td></tr><tr><td>2016</td><td>$ 53,494</td></tr><tr><td>2017</td><td>25,114</td></tr><tr><td>2018</td><td>8,172</td></tr><tr><td>2019</td><td>2,505</td></tr><tr><td>2020</td><td>1,258</td></tr><tr><td>Thereafter</td><td>1,368</td></tr><tr><td></td><td>$ 91,911</td></tr></table>

## 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, 2014 and 2015 there were $33,381 and $33,508, respectively, of self-insurance accruals reflected in accrued expenses of 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 $6,000 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 five customers. Three 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 Euro 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. As discussed in Note 14, we sold our Italian operations on April 27, 2012, and we indemnified the buyers related to certain obligations and contingencies associated with the fire.

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/writedown 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. As a result of the sale of the Italian operations, statements of operations and cash flows related to the fire are 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.

## 11. Related Party Transactions

Paul F. Deninger, one of our directors, is a senior managing director at Evercore Group L.L.C. ("Evercore"). In May 2013, we entered into an agreement with Evercore, which was amended and restated in August 2013 (the "Evercore Engagement"), pursuant to which Evercore agreed to provide financial advisory services to us in exchange for an aggregate fee of up to $3,000. In connection with the Evercore Engagement, Mr. Deninger agreed, and Evercore represented, that Mr. Deninger would not be involved with the Evercore Engagement and would not receive any fees or direct compensation in connection with the Evercore Engagement. The Evercore Engagement was approved by the audit committee of our board of directors in accordance with our Related Persons Transaction Policy. For the years ended December 31, 2013 and 2014, we incurred fees associated with the Evercore Engagement, including fees associated with the amendment of our Former Credit Agreement in August 2013 and discounts and commissions attributable to Evercore's participation as one of the underwriters in the August 2013 Offerings, as well as monthly retention fees, of $2,750 and $250, respectively. We did not incur any fees with Evercore during the year ended December 31, 2015.

## 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 expensed $19,999, $18,306 and $16,355 for the years ended December 31, 2013, 2014 and 2015, respectively.

## 13. Stockholders' Equity Matters

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

On September 15, 2014, we announced the declaration by our board of directors of a special distribution of $700,000 (the "Special Distribution"), payable to stockholders of record as of September 30, 2014 (the "Record Date"). The Special Distribution represented the remaining amount of our undistributed earnings and profits attributable to all taxable periods ending on or prior to December 31, 2013, which in accordance with tax rules applicable to REIT conversions, we were required to pay to our stockholders on or before December 31, 2014 in connection with our conversion to a REIT. The Special Distribution also included certain items of taxable income that we recognized in 2014, such as depreciation recapture in respect of accounting method changes commenced in our pre-REIT period as well as foreign earnings and profits recognized as dividend income. The Special Distribution followed an initial special distribution of $700,000 paid to stockholders in November 2012.

## 13. Stockholders' Equity Matters (Continued)

The Special Distribution was paid on November 4, 2014 (the "Payment Date") to stockholders of record as of the Record Date in a combination of common stock and cash. Stockholders had the right to elect to be paid their pro rata portion of the Special Distribution in all common stock or all cash, with the total cash payment to stockholders limited to no more than $140,000, or 20% of the total Special Distribution, not including cash paid in lieu of fractional shares. Based on stockholder elections, we paid $140,000 of the Special Distribution in cash, not including cash paid in lieu of fractional shares, with the balance paid in the form of common stock. Our shares of common stock were valued for purposes of the Special Distribution based upon the average closing price on the three trading days following October 24, 2014, or $35.55 per share, and as such, we issued approximately 15,750,000 shares of common stock in the Special Distribution. These shares impact weighted average shares outstanding from the date of issuance, and thus impact our earnings per share data prospectively from the Payment Date.

In November 2014, our board of directors declared a distribution of $0.255 per share (the "Catch-Up Distribution") payable on December 15, 2014 to stockholders of record on November 28, 2014. Our board of directors declared the Catch-Up Distribution because our cash distributions paid from January 2014 through July 2014 were declared and paid before our board of directors had determined that we would elect REIT status effective January 1, 2014 and were lower than they otherwise would have been if the final determination to elect REIT status effective January 1, 2014 had been prior to such distributions.

In 2014 and 2015, our board of directors declared the following dividends:

<table><tr><td>Declaration Date</td><td>Dividend Per Share</td><td>Record Date</td><td>Total Amount</td><td>Payment Date</td></tr><tr><td>March 14, 2014</td><td>$ 0.2700</td><td>March 25, 2014</td><td>$ 51,812</td><td>April 15, 2014</td></tr><tr><td>May 28, 2014</td><td>0.2700</td><td>June 25, 2014</td><td>52,033</td><td>July 15, 2014</td></tr><tr><td>September 15, 2014</td><td>0.4750</td><td>September 25, 2014</td><td>91,993</td><td>October 15, 2014</td></tr><tr><td>September 15, 2014(1)</td><td>3.6144</td><td>September 30, 2014</td><td>700,000</td><td>November 4, 2014</td></tr><tr><td>November 17, 2014(2)</td><td>0.2550</td><td>November 28, 2014</td><td>53,450</td><td>December 15, 2014</td></tr><tr><td>November 17, 2014</td><td>0.4750</td><td>December 5, 2014</td><td>99,617</td><td>December 22, 2014</td></tr><tr><td>February 19, 2015</td><td>0.4750</td><td>March 6, 2015</td><td>99,795</td><td>March 20, 2015</td></tr><tr><td>May 28, 2015</td><td>0.4750</td><td>June 12, 2015</td><td>100,119</td><td>June 26, 2015</td></tr><tr><td>August 27, 2015</td><td>0.4750</td><td>September 11, 2015</td><td>100,213</td><td>September 30, 2015</td></tr><tr><td>October 29, 2015</td><td>0.4850</td><td>December 1, 2015</td><td>102,438</td><td>December 15, 2015</td></tr></table>

(1) Represents Special Distribution.

(2) Represents Catch-Up Distribution.

During the years ended December 31, 2013, 2014 and 2015, we declared distributions to our stockholders of $206,365, $1,048,905 and $402,565, respectively. These distributions represent approximately $1.08 per share, $5.37 per share and $1.91 per share for the years ended December 31, 2013, 2014 and 2015, respectively, based on the weighted average number of common shares outstanding during each respective year. For 2014, total amounts distributed included the Special Distribution of $700,000, or $3.61 per share, associated with our conversion to a REIT.

## 13. Stockholders' Equity Matters (Continued)

For federal income tax purposes, distributions to our stockholders are generally treated as nonqualified ordinary dividends, qualified ordinary dividends or return of capital. The United States Internal Revenue Service requires historical C corporation earnings and profits to be distributed prior to any REIT distributions, which may affect the character of each distribution to our stockholders, including whether and to what extent each distribution is characterized as a qualified or nonqualified ordinary dividend. For the years ended December 31, 2013, 2014 and 2015, the dividends we paid on our common shares were classified as follows:

<table><tr><td rowspan="2"></td><td colspan="3">Year Ended December 31,</td></tr><tr><td>2013</td><td>2014</td><td>2015</td></tr><tr><td>Nonqualified ordinary dividends</td><td>0.0%</td><td>26.4%</td><td>49.3%</td></tr><tr><td>Qualified ordinary dividends</td><td>100.0%</td><td>56.4%</td><td>39.1%</td></tr><tr><td>Return of capital</td><td>0.0%</td><td>17.2%</td><td>11.6%</td></tr><tr><td></td><td>100.0%</td><td>100.0%</td><td>100.0%</td></tr></table>

## 14. Discontinued Operations

## Digital Operations

On June 2, 2011, we sold (the “Digital Sale”) our online backup and recovery, digital archiving and eDiscovery solutions businesses of our digital business (the “Digital Business”) to Autonomy Corporation plc, a corporation formed under the laws of England and Wales (“Autonomy”), pursuant to a purchase and sale agreement dated as of May 15, 2011 among IMI, certain subsidiaries of IMI and Autonomy. In the Digital Sale, Autonomy purchased (1) the shares of certain of IMI’s subsidiaries through which we conducted the Digital Business and (2) certain assets of IMI and its subsidiaries relating to the Digital Business. The Digital Sale qualified as discontinued operations and, as a result, the financial position, operating results and cash flows of the Digital Business, for all periods presented, have been reported as discontinued operations for financial reporting purposes.

The table below summarizes certain results of operations of the Digital Business:

<table><tr><td rowspan="2"></td><td colspan="4">Year Ended December 31,</td></tr><tr><td>2013</td><td>2014</td><td>2015</td><td></td></tr><tr><td>(Loss) Income Before (Benefit) Provision for Income Taxes of Discontinued Operations</td><td>$ (958)</td><td>$ (960)</td><td>$ —</td><td></td></tr><tr><td>(Benefit) Provision for Income Taxes</td><td>(429)</td><td>—</td><td>—</td><td></td></tr><tr><td>(Loss) Income from Discontinued Operations, Net of Tax</td><td>$ (529)</td><td>$ (960)</td><td>$ —</td><td></td></tr></table>

During the year ended December 31, 2013, we recognized a loss before provision of income taxes of discontinued operations of $958 primarily related to the write-off of certain software costs. During the year ended December 31, 2014, we recognized a loss before provision for income taxes of discontinued operations of $960, primarily related to settlements of legal matters directly related to the disposed business.

## Italian Operations

We sold our Italian operations on April 27, 2012, and we agreed to indemnify the buyers of our Italian operations for certain possible obligations and contingencies associated with the fire in Italy discussed more fully in Note 10.d. Our Italian operations were previously included within the Western European Business segment. For all periods presented, the financial position, operating results and cash flows of our Italian operations, including the loss on the sale, have been reported as discontinued operations for financial reporting purposes.

(1) During the years ended December 31, 2013 and 2014, we recognized income before provision of income taxes of discontinued operations primarily related to the recovery of insurance proceeds in excess of carrying value.

## 15. Cost Optimization Plans

## Organizational Restructuring

During the third quarter of 2013, we implemented a plan that called for certain organizational realignments to advance our growth strategy and reduce operating costs (the “Organizational Restructuring”), which was completed in 2014. As a result of the Organizational Restructuring, we recorded charges of $23,400 and $3,475 for the years ended December 31, 2013 and 2014, respectively, primarily related to employee severance and associated benefits. Costs included in the accompanying Consolidated Statements of Operations associated with the Organizational Restructuring are as follows:

<table><tr><td rowspan="2"></td><td colspan="3">Year Ended December 31,</td></tr><tr><td>2013</td><td>2014</td><td>2015</td></tr><tr><td>Cost of sales (excluding depreciation and amortization)</td><td>$ 3,400</td><td>$ 1,228</td><td>$ —</td></tr><tr><td>Selling, general and administrative expenses</td><td>20,000</td><td>2,247</td><td>—</td></tr><tr><td>Total</td><td>$ 23,400</td><td>$ 3,475</td><td>$ —</td></tr></table>

## 15. Cost Optimization Plans (Continued)

## Transformation Initiative

During the third quarter of 2015, we implemented a plan that calls for certain organizational realignments to reduce our overhead costs, particularly in our developed markets, in order to optimize our selling, general and administrative cost structure and to support investments to advance our growth strategy (the “Transformation Initiative”), which is expected to be completed by the end of 2017. As a result of the Transformation Initiative, we recorded charges of $10,167 for the year ended December 31, 2015, primarily related to employee severance and associated benefits. Costs included in the accompanying Consolidated Statements of Operations associated with the Transformation Initiative are as follows:

<table><tr><td rowspan="2"></td><td colspan="4">Year Ended December 31,</td></tr><tr><td>2013</td><td>2014</td><td>2015</td><td></td></tr><tr><td>Cost of sales (excluding depreciation and amortization)</td><td>$ —</td><td>$ —</td><td>$ —</td><td>—</td></tr><tr><td>Selling, general and administrative expenses</td><td>—</td><td>—</td><td>10,167</td><td></td></tr><tr><td>Total</td><td>$ —</td><td>$ —</td><td>$ 10,167</td><td></td></tr></table>

We had accrued $2,291 as of December 31, 2015 related to the Transformation Initiative. We expect that this liability will be paid throughout the first half of 2016.

In the first quarter of 2016, we implemented additional actions associated with our Transformation Initiative. As a result of these actions, we expect to record a charge of approximately $7,000, primarily related to employee severance and associated benefits, and included as a component of selling, general and administrative expenses. Of this charge, approximately $4,400, $700, $100 and $1,800 was associated with our North American Records and Information Management Business, North American Data Management Business, Western European Business and Corporate and Other Business segments, respectively.

## 16. Divestitures

In December 2014, we divested our secure shredding operations in Australia, Ireland and the United Kingdom (the "International Shredding Operations") in a stock transaction for approximately $26,200 in cash at closing, including $1,500 being held in escrow. The assets sold primarily consisted of customer contracts and certain long-lived assets. We have concluded that this divestiture did not meet the requirements to be presented as a discontinued operation, and, therefore, have recorded a pretax gain on sale in other (income) expense, net of approximately $6,900 ($10,200, inclusive of a tax benefit) in our Consolidated Statement of Operations for the year ended December 31, 2014. Revenues from our International Shredding Operations in 2014 represented less than 1% of our consolidated revenues. Approximately $7,750 of goodwill was allocated to the International Shredding Operations, utilizing a relative fair value approach. The International Shredding Operations in Australia were previously included in the Other International Business segment and the International Shredding Operations in the United Kingdom and Ireland were previously included in the Western European Business segment.

## CAUTIONARY NOTE REGARDING
FORWARD-LOOKING STATEMENTS

The stockholder letter contains certain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 and other securities laws and is subject to the safe-harbor created by such Act. Forward-looking statements include our financial performance outlook and statements regarding our operations, economic performance, financial condition, goals, beliefs, future growth strategies, investment objectives, plans and current expectations, such as projected revenues from our emerging market acquisition pipeline, valuation creation and returns associated with our data center business, and the acquisition of currently leased facilities. These forward-looking statements are subject to various known and unknown risks, uncertainties and other factors. When we use words such as “believes,” “expects,” “anticipates,” “estimates” or similar expressions, we are making forward-looking statements. You should not rely upon forward-looking statements except as statements of our present intentions and of our present expectations, which may or may not occur. Although we believe that our forward-looking statements are based on reasonable assumptions, our expected results may not be achieved, and actual results may differ materially from our expectations. In addition, important factors that could cause actual results to differ from our other expectations include, among others: (i) our ability to remain qualified for taxation as a real estate investment trust for U.S. federal income tax purposes; (ii) the adoption of alternative technologies and shifts by our customers to storage of data through nonpaper based technologies; (iii) changes in customer preferences and demand for our storage and information management services; (iv) the cost to comply with current and future laws, regulations and customer demands relating to privacy issues; (v) the impact of litigation or disputes that may arise in connection with incidents in which we fail to protect our customers’ information; (vi) changes in the price for our storage and information management services relative to the cost of providing such storage and information management services; (vii) changes in the political and economic environments in the countries in which our international subsidiaries operate; (viii) our ability or inability to complete acquisitions on satisfactory terms and to integrate acquired companies efficiently; (ix) changes in the amount of our capital expenditures; (x) changes in the cost of our debt; (xi) the impact of alternative, more attractive investments on dividends; (xii) the cost or potential liabilities associated with real estate necessary for our business; (xiii) the performance of business partners upon whom we depend for technical assistance or management expertise outside the United States; (xiv) other trends in competitive or economic conditions affecting our financial condition or results of operations not presently contemplated; and (xv) other risks described more fully in our Annual Report on Form 10-K filed with the Securities and Exchange Commission, or SEC, on February 26, 2016 under “Item 1A. Risk Factors” and other documents that we file with the SEC from time to time. Except as required by law, we undertake no obligation to release publicly the result of any revision to these forward-looking statements that may be made to reflect events or circumstances after the date hereof or to reflect the occurrence of unanticipated events.
