rely upon Equinix IBX data centers for many of their critical interconnection relationships. The need for sizable, wholesale, outsourced data centers is also being addressed by providers that build large data centers to meet customers’ needs for standalone data centers, a different customer segment than Equinix serves.
Due to the increasing cost and complexity of the power and cooling requirements of today’s data center equipment, Equinix has gained many customers that have outgrown their existing data centers or have realized the benefits of a network-neutral model and the ability to create their own optimized business ecosystems for the exchange of data. Strategically, we will continue to look at attractive opportunities to grow market share and selectively expand our footprint and offerings. We continue to leverage our global reach and depth to differentiate Equinix based upon our ability to support truly global customer requirements in all our markets.
Equinix is benefiting from a growth in demand for data center offerings. Several factors contribute to this growth in demand, including:
The growth of “proximity communities” that rely on immediate physical colocation and interconnection with their strategic partners and customers, such as financial exchange ecosystems for electronic trading and settlement and ecosystems for real-time bidding and fulfillment of Internet advertising.
The adoption of cloud computing technology services, including the growth of hybrid/multi-clouds, enterprise cloud service offerings such as Software-as-a-Service (SaaS), Infrastructure-as-a-Service (IaaS) and Platform-as-a-Service (PaaS) and disaster recovery services.trends.
The continuing growth of consumer Internet traffic from new bandwidth-intensive services, such as video, voice over IP (VoIP), social media, mobile data, gaming, data-rich media, Ethernet and wireless services. The financial services market is experiencing tremendous growth due to electronic trading and the increased volume of peak messages (transactions per second), requiring optimized data exchange through business ecosystems.
The increasing requirements for anytime, anywhere and any device interconnection out at the edge of the corporate network to improve the performance, security, scalability and reliability of interconnecting people, locations, clouds and data.
Significant increases in power and cooling requirements for today’s data center equipment. New generations of servers continue to concentrate processing capability, with associated power consumption and cooling load, into smaller footprints, and many legacy-built data centers are unable to accommodate these new power and cooling demands. The high capital costs associated with building and maintaining “in-sourced” data centers creates an opportunity for capital savings by leveraging an outsourced colocation model.
Industry Background
The Internetinternet is a collection of numerous independent networks interconnected to form a network of networks. Users on different networks are able to communicate with each other through interconnection between these networks. For example, when a person sends an email to someone who uses a different provider for his or her connectivity (e.g., Comcast versus Verizon)AT&T), the email must pass from one network to the other to get to its final destination. EquinixA data center provides a physical point at which that interconnection can occur.

To accommodate the rapid growth of Internetinternet traffic that was occurring in the early years of the internet, an organized approach for network interconnection was needed. This was the start of the network era, when networks gained mutual advantage by exchanging data traffic on interoperable platforms. The exchange of traffic between these networks became known as peering. Peeringpeering, which is when networks agree to trade traffic at relatively equal amounts, and set up agreements to trade traffic, often at no charge to the other party. At first, government and nonprofit organizations established places where these networks could exchange traffic, or peer with each other-theseother. These points were known as network access points, or NAPs. Over time, many NAPs became a natural extension of carrier services and were run by companies such companies as MFS (now a part of Verizon Business), Sprint, Ameritech and Pacific Bell (the latter two are now part of AT&T).
Ultimately, these NAPs were unable to scale with the growth of the Internet,internet, and the lack of “neutrality”"neutrality" by the carrier owners of these NAPs created a conflict of interest with the participants. This created a market need for network-neutral interconnection points that could accommodate the rapidly growing needdemand to increase performance for enterprise and consumer users of the Internet,internet, especially with the rise of important content providers such as AOL, Microsoft, Yahoo! and others. In addition, the providers, as well as a growing number of enterprises, required a more secure and reliable solution for direct connection to a variety of

telecommunications networks, as the importance of their Internetinternet operations continued to grow. These were the seeds of the connected era, when peering expanded exponentially and betweenamong new players, and access to information anytime and anywhere became the norm.
To accommodate Internetinternet traffic growth, the largest networks left the NAPs and began connecting and trading traffic by placing private circuits between each other. Peering, which once occurred at the NAP locations, was moved to these private circuits. Over the years, these circuits became expensive to expand and could not be built quickly enough to accommodate traffic growth. This led to a need by the large carriers to find a more efficient way to peer. The multi-tenant or colocation data center was introduced to meet this need. Today, many customers satisfy their requirements for peering through data center providers like Equinix because this strategy permits them to peer with the networks they require within one location, using simple, direct and secure connections. Their ability to peer within a data center or across a data center campus, instead of across a metro area, has increased the scalability of their operations while decreasing network costs.
The interconnection model has further evolved over the years to include new offerings, as the collaborative landscape of the interconnected era imposes new demands on connectivity. As enterprises becomefor connectivity that facilitates more scalable interactive and real-time digital interconnections. Enterprises are becoming increasingly interdependent and cloud-enabled,cloud- and digital-enabled, and to compete they need real-time data exchange and reliable, instant connections between the various corners ofand across any given digital ecosystem to compete.ecosystem. Starting with the peering and network communities, interconnection has been used for new network services,solutions, including carrier Ethernet, multiprotocol label switching (MPLS), virtual private networks (VPNs), and mobile services, in addition to traditional international private line and voice services. The data center industry continues to evolve with a set of new offerings where interconnection is often used to solve the network-to-network and the cloud-to-cloud interconnection challenges in orderworking to keep up with the rapid digital transformation of today’s businesses.today's businesses, and it continues to evolve with a set of new network offerings (such as SDN, blockchain and 5G) where interconnection is often used to solve any challenge using both physical and virtual networks, across geographic boundaries.
In addition, the enterprise customer segment is also evolving. In the past, most enterprises opted to keep their data center requirements in house.in-house. However, current trends are leading more and more enterprise chief information officers (CIOs) to either outsource their data center requirements, and/or extend their corporate wide area networks (WANs) into carrier-neutral colocation facilities. facilities where there are dense ecosystems of network, cloud and IT service providers, and business partners that enterprises can directly and securely interact with in real-time.
The combinationfollowing are macro, technology and regulatory trends that are forcing enterprises and service providers across all industries to rethink their IT architectures to decrease complexity and cost, and seize new opportunities to compete successfully as digital businesses:
Digital businesstransformation is becoming a global phenomenon. According to IDC, by 2021 at least 50% of globalization,global GDP will be digitized, and growth in every industry will be driven by digitally enhanced offerings, operations and relationships. Interconnection becomes a key building block for digital business along that journey because real-time interactions between people, things, locations, clouds and data are critical in a digital age.

Urbanization is increasing in the proliferationmajority of bandwidth intensive Internet-facingmetros worldwide. Today, about 55% of the world's population lives in urban areas, and that will grow to 68% by 2050, according to the United Nations. With so many people so close together, digital services must be increasingly concentrated and close to users, so companies can deliver the connectivity their users expect. Interconnection brings applications, data, content and rich media content,networking into proximity in these densely populated areas. It allows companies to deliver on their service promises, even as demand keeps growing.


Cybersecurity has increased in frequency, scope and complexity in our more closely connected world. In fact, a large-scale cybersecurity breach is one of the most serious risks facing companies today. Ernst & Young projects the global cost of cybersecurity breaches will reach $6.0 trillion by 2021. Companies need to provide accessstrengthen their defenses, even as they increase their vulnerability by distributing their data across a variety of sources and users. To do that, businesses need their security controls to be distributed as well, leveraging interconnection out at the edge where most traffic exchange is happening. The direct, private nature of interconnection also increases data protection and lowers the risk of being compromised.

Data Compliance has become a mandate among businesses around the world. The digital economy may be global, but more countries are regulating the data at the heart of the digital economy and prescribing enhanced rules around personal data protections (e.g., GDPR). But remaining compliant is about more than following the rules. In a Thompson Reuters survey, 69% of respondents said successful compliance efforts can drive up business efficiency and effectiveness by enabling greater focus on value-added activities. The need to address compliance drives interconnection because it enables companies to link their data storage, analytics and clouds in the same business region. That data can stay proximate, and local if required by regulations, but still be accessed globally to meet business requirements.

Business Ecosystemsare becoming the life-blood of digital business. Gartner predicts that by 2021, the number of organizations using a mix of intermediaries will more than double, and that active engagement by these organizations with industries in ecosystems outside their native industry will nearly triple. The reason is that digital trade flows are creating global business and data processes that involve an increasing variety of customers, partners and employees. Interconnection securely and efficiently connects all the players in all these business ecosystems, as those ecosystems expand in depth and number
Other trends that we see impacting our customers' IT strategies include:
The need for businesses and organizations to create a "digital edge" - where commerce, population centers and digital ecosystems meet. A more geographically distributed IT infrastructure is needed to support the digital operations that now cover every global region and every aspect of today's global businesses.

The growth of "proximity communities" that rely on immediate physical colocation and interconnection with strategic partners and customers. Examples include financial exchange ecosystems for electronic trading and settlement, media and content provider ecosystems, and ecosystems for real-time bidding and fulfillment of internet advertising.

The Internet of Things (IoT), big data infrastructures, artificial intelligence (AI) and the emergence of 5G high-speed mobile and wireless networks, which are creating unprecedented quantities of data that fuel digital business.

The accelerating adoption and ubiquitous nature of cloud computing environmentstechnology services, in particular hybrid/multiclouds, along with enterprise cloud service offerings such as Software-as-a-Service (SaaS), Infrastructure-as-a-Service (IaaS) and business continuityPlatform-as-a-Service (PaaS) and security and disaster recovery options, plus tight corporate IT budgets, mean that enterprise CIOs must do moreservices.

The continuing growth of consumer internet traffic from new bandwidth-intensive services (e.g., video, voice over IP, social media, mobile data, gaming, data-rich media), Ethernet and wireless services, as well as new devices (e.g., wearables, home assistances, AR/VR headsets). These devices and services also increase the requirements for anytime, anywhere and any device interconnection out at the edge to improve the performance, security, scalability and reliability of interconnecting people, locations, clouds, data and things.

Significant increases in power and cooling requirements for today's data center equipment. New generations of servers and storage devices continue to concentrate processing capability and the associated power consumption and cooling load into smaller footprints; and many legacy-built data centers are unable to accommodate these new power and cooling demands. The high capital costs associated with less. building and maintaining "in-sourced" data centers creates an opportunity for capital savings by leveraging an outsourced colocation model.
Industry analysts forecastproject the compound annual growth inrate of the global carrier neutral colocation market to be approximately 10% per year over the next four years.8.4% between 2018 and 2022.

Accelerate global reach and scale. We continue to evaluate expansion opportunities in select markets based on customer demand. In 2014,April 2018, we purchased the 1.6 million-square foot Infomart Building™ in Dallas, including its operations and tenants, where we had already been operating four data centers. Also, in April 2018, we completed theour acquisition of ALOG Data Centers of Brazil S.A.Australian data center provider Metronode and took the remaining ownership interest in the fourits 10 data centers, at ALOG, obtainingwhich expanded our operations into Adelaide, Brisbane, Canberra and Perth, and added scale in Melbourne and Sydney. This acquisition tripled our Australian data center footprint to 15 sites. Careful, steady expansion has been key to our growth strategy since our founding, as we seek to offer our customers interconnection opportunities ahead of demand. As of the remaining ownership interest in four data centers, two in São Paulo and two in Rio de Janeiro. In 2015, we acquired professional services company Nimbo in the U.S. and Bit-isle in Japan.

The TelecityGroup acquisition significantly expandsend of 2018, Equinix's total global interconnection platform from 112footprint had expanded to 200 data centers in 33 metros to 145 data centers52 markets in 40 metros. The new metros we entered with our TelecityGroup acquisition in 2016 were Dublin, Helsinki, Istanbul, Milan, Sofia, Stockholmthe Americas, EMEA and Warsaw. We also added capacity across our global footprint in 2015 by opening our ninth data center in New York, our second in Toronto, our first in Melbourne, our third in Singapore and our sixth in London.Asia-Pacific.
Our strategy isWe expect to continue to grow in select existing markets and possibly expand to additional markets where warranted by demand and financial return potential. We expect to execute thisour global expansion strategy in a cost-effective and disciplined manner through a combination of acquiring existing data centers through lease or purchase, acquiring or investing in local data center operators, and building new IBX data centers based on key criteria, such as demand and potential financial return in each market.

Our Competition
While a large number of enterprises own their own data centers, many others outsource some or all of their requirements to multi-tenant Internet data center (MTDC) facilities, such as those operated by Equinix. We believe that the outsourcing trend is likely to not only continue but also to growaccelerate in the coming years. The global MTDC market is highly fragmented. It is estimated that Equinix is one of more than 6501,200 companies that provide Internet data centerMTDC offerings around the world, ranging in size from firms with a single data center in a single market to firms in over 20 markets. Equinix competes with these firms which vary in terms of their data center offerings, including:
Colocation Providers

InProviders in addition to Equinix providers that offer colocation both globally and locally include firms such as AT&T, CenturyLink, COLT CyrusOne, Level 3 Communications, NTT and Verizon Business.NTT.
Carrier-Neutral Colocation Providers
In addition to data center space and power, colocation providers also offer interconnection. CertainSome of these providers, known as network or carrier-neutral colocation providers, can offer customers the choice of hundreds of network service providers or ISPs to choose from. Typically, customers use interconnection to buy Internetethernet or internet connectivity, connect to VoIP telephone networks, perform financial exchange and settlement functions or perform business-to-business e-commerce. Carrier-neutral data centers are often located in key network hubs around the world, such as New York, Ashburn, Va., London, Amsterdam, Singapore and Hong Kong. Two types of data center facilities offering carrier-neutral colocation are used for many network-to-network interconnections:
A Meet Me Room (MMR) is typically a smaller space, generally 5,000 square feet or less, located in a major carrier hotel and often found in a wholesale data center facility.
A carrier-neutral data center is generally larger than an MMR and may be a stand-alone building separate from existing carrier hotels.
In
Providers in addition to Equinix other providers that we believe could be defined as offering carrier-neutral colocation include CoreSite, Digital Reality,Realty Trust, Global Switch, Interxion and Telehouse.
Wholesale Data Center Providers
Wholesale data center providers lease data center space that is typically offered in cells or pods (i.e., individual white-space rooms) ranging in size from 10,000 to 20,000 square feet or larger. Wholesale data center offerings are targeted to both enterprises and colocation providers. These data centers primarily provide space and power without additional services like technicians, remote hands services or network monitoring (although other tenants might offer such services).
Sample wholesale data center providers include Digital Realty Trust DuPont Fabros Technology, e-Shelter and Global Switch.

Managed HostersHosting Providers
Managed hosting services are provided by several firms that also provide data center colocation services.solutions. Typically, managed hosting providers can manage server hardware that is owned by either the hosting provider or the customer. They can also provide a combination of comprehensive systems administration, database administration and sometimes application management services. Frequently, this results in managed hosting providers “running”"running" the customer’scustomer's servers, although such administration is frequently shared. The provider may manage such functions as operating systems, databases, security and patch management, while the customer will maintain management of the applications riding on top of those systems.
The full list of potential services that can be offered as part of managed hosting is substantial and includes services such as remote management, custom applications, helpdesk, messaging, databases, disaster recovery, managed storage, managed virtualization, managed security, managed networks and systems monitoring. Managed hosting services are typically used for:

Unlike other providers whose core businesses are bandwidth or managed services, we focus on neutral interconnection hubs for cloud and IT service providers, content providers, financial companies, enterprises and network service providers. As a result, we do not have the limited choices found commonly at other hosting/colocation companies. We compete based on the quality of our IBX data centers, our ability to provide a one-stop global solution in our Americas, EMEA and Asia-Pacific locations, the performance and diversity of our network- and cloud-neutral strategy, and the economic benefits of the aggregation of top network, cloud and business ecosystems under one roof. We expect to continue to benefit from severalprevailing industry trends, including the need for contracting with multiple networks due to create a “digital edge”, the uncertainty ingrowth of proximity communities, the telecommunications market; customers’ increasing power requirements; enterprise customers’ increased useadoption of virtualization and outsourcing;IOT, AI, 5G cloud computing, the continued growth of broadband and significant growth in Ethernet as a network alternative;internet traffic and the growth in mobile applications.increased power and cooling requirements of new generations of IT equipment.

ITEM 1A.RISK FACTORS
In addition to the other information contained in this report, the following risk factors should be considered carefully in evaluating our business and us:
Risks Related to the Acquisition and Integration of TelecityGroup
We have incurred and will continue to incur significant transaction, acquisition-related integration and asset divestment costs in connection with the consummation of the TelecityGroup acquisition.
We have incurred and will continue to incur significant costs in connection with consummating the TelecityGroup acquisition and integrating our and TelecityGroup’s operations into a combined company. We will also incur costs in connection with the divestment of certain of the assets of the combined company. The actual costs incurred may exceed those estimated and there may be further unanticipated costs and the assumption of known and unknown liabilities. While we have assumed that we will incur transaction, integration and divestment expenses, there are factors beyond our control that could affect the total amount or the timing of such expenses. Many of the expenses that will be incurred, by their nature, are difficult to estimate accurately at the present time.
As a result, the transaction, integration and divestment expenses associated with the TelecityGroup acquisition could, particularly in the near term, exceed the cost savings that we expect to achieve from the streamlining of operations following the completion of the TelecityGroup acquisition.
The anticipated benefits of the TelecityGroup acquisition may not be realized fully and may take longer to realize than expected and there will be numerous challenges associated with integration.
The success of the TelecityGroup acquisition will depend, in part, on the combined company’s ability to successfully integrate our and TelecityGroup’s businesses and realize the anticipated benefits, including synergies and cost savings, from the combination. If we are unable to achieve these objectives within the anticipated time frame, or at all, the anticipated benefits may not be realized fully or at all, or may take longer to realize than expected and the value of the combined company’s common stock may be adversely affected. We also must successfully divest certain assets of the combined company agreed upon with the European Commission in order to obtain clearance of the transaction, which could reduce certain of the benefits we expect to receive from the TelecityGroup acquisition.
We have incurred and will continue to incur significant transaction-related costs in connection with the TelecityGroup acquisition and the integration and divestment processes. We may encounter material challenges in connection with this integration process, including, without limitation:
the diversion of management’s attention from ongoing business concerns and performance shortfalls at one or both of the companies as a result of the devotion of management’s attention to the TelecityGroup integration;
managing a larger combined company;
integrating two unique corporate cultures, which may prove to be challenging;
retaining key employees, customers and suppliers, each of whom may experience uncertainty associated with the TelecityGroup acquisition or who may attempt to negotiate changes in their current or future business relationships with us;
consolidating corporate and administrative infrastructures and eliminating duplicative operations; and
unforeseen expenses or delays associated with the TelecityGroup acquisition.
Many of these factors will be outside of our control and any one of them could result in increased costs, decreases in the amount of expected revenues and diversion of management’s time and energy, which could materially impact our business, financial condition and results of operations.

14


The market price of our common stock may decline as a result of the TelecityGroup acquisition.
The market price of our common stock may decline as a result of the TelecityGroup acquisition if we do not achieve the perceived benefits of the TelecityGroup acquisition as rapidly or to the extent anticipated by financial or industry analysts or if the effect of the TelecityGroup acquisition on our financial results is not consistent with the expectations of financial or industry analysts. In addition, TelecityGroup shareholders now own approximately 10% of the common stock outstanding, and they may decide to sell their common stock which may result in additional pressure on the price of our common stock.
We would incur adverse tax consequences if the combined company following the TelecityGroup acquisition fails to qualify as a REIT for U.S. federal income tax purposes.
We believe that we will continue to integrate TelecityGroup’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, the TelecityGroup integration will be complicated due to the size of TelecityGroup and if we fail to timely satisfy such tests, 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 Internal Revenue Code (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 would thus be subject to U.S. federal and state income tax at the regular corporate rates on all of our U.S. 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 TelecityGroup acquisition.
Risks Related to Our Taxation as a REIT
We may not remain qualified for taxation as a REIT.
We began operating as a REIT for federal income tax purposes, effective for our taxable year that began January 1, 2015. We believe we are operating so as to qualify for taxation as a REIT under the Code and believe that our organization and method of operation complies with the rules and regulations promulgated under the Code and will enable us to continue to qualify for taxation as a REIT. However, we cannot assure you that we will qualify for taxation as a REIT or that we will remain qualified for taxation as a REIT. Qualification for taxation as a REIT requires us to satisfy numerous requirements (some on an annual and others on a quarterly basis) established under highly technical and complex sections of the Code which may change from time to time; and for which there are only limited judicial and administrative interpretations, and involves the determination of various factual matters and circumstances not entirely within our control. For example, in order to qualify for taxation as a REIT, we must derive at least 95% of our gross income in any year from qualifying sources. In addition, we must satisfy specified asset tests on a quarterly basis.
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 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.
As a REIT, failure to make required distributions would subject us to federal corporate income tax.
We paid quarterly distributions in 2015. We also paid the 2015 Special Distribution (as defined below) in the fourth quarter of 2015. The amount, timing and form of any future distributions will be determined, and will be subject to adjustment, by our

15


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 payment of expenses and the recognition of income and expenses for federal income tax purposes, or the effect of nondeductible expenditures, such as capital expenditures, payments of compensation for which Section 162(m) of the Code denies a deduction, the creation of reserves or required debt service or amortization payments.
To the extent that we satisfy the 90% distribution requirement but distribute less than 100% of our REIT taxable income, we will be subject to federal corporate income tax on our undistributed taxable income. In addition, we will be subject to a 4% nondeductible excise tax on our undistributed taxable income if the actual amount that we distribute to our stockholders for a calendar year is less than the minimum amount specified under the Code.
We may be required to borrow funds or raise equity to satisfy our REIT distribution requirements.
Due to the size and timing of future regular or special distributions, including any distributions made to satisfy REIT distribution requirements and maintain our qualification and taxation as a REIT, we may need to borrow funds or raise equity, even if the then-prevailing market conditions are not favorable for these borrowings 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 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. A significant 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. Significantly more 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 “Other Risks”.
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.
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 IRS, the U.S. 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 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 forego otherwise attractive opportunities.
As a REIT for U.S. federal income tax purposes, we must satisfy tests concerning, among other things, the sources of our income, the nature and diversification of our assets and the amounts we distribute to our stockholders. For example, under the Code, no more than 25% (20% from and after our 2018 taxable year) of the value of the assets of a REIT may be represented by securities of one or more TRSs. Similar rules apply to other nonqualifying assets. These limitations may affect our ability to make large investments in other non-REIT qualifying operations or assets. In addition, in order to maintain qualification for taxation as a REIT, we must annually distribute at least 90% of our REIT taxable income, determined without regard to the dividends paid

16


deduction and excluding any net capital gains. Even if we maintain our qualification for taxation as a REIT, we will be subject to U.S. federal income tax at regular corporate rates for our undistributed REIT taxable income, as well as U.S. federal income tax at regular corporate rates for income recognized by our TRSs. Because of these distribution requirements, we will likely not be able to fund future capital needs and investments from operating cash flow. As such, compliance with REIT tests may hinder our ability to make certain attractive investments, including the purchase of significant nonqualifying assets and the material expansion of non-real estate activities.
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. 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% or from and after our 2018 taxable year, 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 and any stock repurchase program. 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.
A portion of our business is conducted through wholly owned TRSs because certain of our business activities could generate nonqualifying REIT income as currently structured and operated. The income of our U.S. TRSs will continue to be subject to federal and state corporate income taxes. In addition, our international assets and operations will continue to be subject to taxation

17


in the foreign jurisdictions where those assets are held or those operations are conducted. Any of these taxes would decrease our earnings and our available cash.
We will also be subject to a federal corporate level tax at the highest regular corporate 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 present or former C corporation (such as (i) an asset that we held as of the effective date of our REIT election, that is, January 1, 2015, 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, 2015 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, 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.
Restrictive loan covenants could prevent us from satisfying REIT distribution requirements.
Restrictions in our credit facility and our indentures may prevent us from satisfying our REIT distribution requirements, and we could fail to remain qualified for taxation as a REIT. If these limits do not jeopardize our qualification for taxation as a REIT but nevertheless prevent us from distributing 100% of our REIT taxable income, we would be subject to federal corporate income tax, and potentially a nondeductible excise tax, on the retained amounts. See “Other Risks” for further information on our restrictive loan covenants.
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 or fluctuations with respect to borrowings made or to be made by us to acquire or carry real estate assets and income from certain currency hedging transactions related to our non-U.S. operations, as well as income from qualifying contracting 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, which we presently do. This increases the cost of our hedging activities because our TRSs are subject to tax on income or gains resulting from hedges entered into by them and may expose us to greater risks associated with changes in interest rates or exchange rates than we would otherwise want to bear. In addition, hedging losses in any of our TRSs may not provide any tax benefit, except for being carried forward for possible use against future capital gain 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 and ability to forecast dividends.
We began operating as a REIT on January 1, 2015 and, as such, have limited operating history as a REIT. In addition, prior to January 1, 2015 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 U.S. 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.

18


Our certificate of incorporation contains restrictions on the ownership and transfer of our stock, though they may not be successful in preserving our qualification for taxation as a REIT.
In order for us to remain qualified for taxation as a REIT, no more than 50% of the value of outstanding shares of our 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 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 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.
Other Risks
Acquisitions present many risks, and we may not realize the financial or strategic goals that were contemplated at the time of any transaction.
Over the last several years, weWe have completed numerous acquisitions including most recently that of Nimbo and Bit-isle in 2015 and TelecityGroup in January of 2016. We mayexpect to make additional acquisitions in the future, whichfuture. These may include (i) acquisitions of businesses, products, servicessolutions or technologies that we believe to be complementary, (ii) acquisitions of new IBX data centers or real estate for development of new IBX data centers or (iii) acquisitions through investments in local data center operators. We may pay for future acquisitions by using our existing cash resources (which may limit other potential uses of our cash), incurring additional debt (which may increase our interest expense, leverage and debt service requirements) and/or issuing shares (which may dilute our existing stockholders and have a negative effect on our earnings per share). Acquisitions expose us to potential risks, including:
the possible disruption of our ongoing business and diversion of management’smanagement's attention by acquisition, transition and integration activities, particularly when multiple acquisitions and integrations are occurring at the same time;
our potential inability to successfully pursue or realize some or all of the anticipated revenue opportunities associated with an acquisition or investment;
the possibility that we may not be able to successfully integrate acquired businesses, or businesses in which we invest, or achieve anticipated operating efficiencies or cost savings;
the possibility that announced acquisitions may not be completed, due to failure to satisfy the conditions to closing as a result of:
an injunction, law or order that makes unlawful the consummation of the acquisition;
inaccuracy or breach of the representations and warranties of, or the non-compliance with covenants by, either party;
the nonreceipt of closing documents; or
for other reasons;
the possibility that there could be a delay in the completion of an acquisition, which could, among other things, result in additional transaction costs, loss of revenue or other negative effects resulting from uncertainty about completion of the respective acquisition;
the dilution of our existing stockholders as a result of our issuing stock as consideration in transactions, such asa transaction or selling stock in connection with our acquisitions of Switch & Data Facilities Company, Inc. in 2010 ("Switch and Data") and TelecityGroup;order to fund the transaction;
the possibility of customer dissatisfaction if we are unable to achieve levels of quality and stability on par with past practices;
the possibility that we will be unable to retain relationships with key customers, landlords and/or suppliers of the acquired businesses, some of which may terminate their contracts with the acquired business as a result of the acquisition or which may attempt to negotiate changes in their current or future business relationships with us;
the possibility that we could lose key employees from the acquired businesses before integrating them;
the possibility that we may be unable to integrate or migrate IT systems, which could create a risk of errors or performance problems and could affect our ability to meet customer service level obligations;
the potential deterioration toin our ability to access credit markets due to increased leverage;
the possibility that our customers may not accept either the existing equipment infrastructure or the “look-and-feel”"look-and-feel" of a new or different IBX data center;

19


the possibility that additional capital expenditures may be required or that transaction expenses associated with acquisitions may be higher than anticipated;
the possibility that required financing to fund an acquisition may not be available on acceptable terms or at all;
the possibility that we may be unable to obtain required approvals from governmental authorities under antitrust and competition laws on a timely basis or at all, which could, among other things, delay or prevent us from completing an acquisition, limit our ability to realize the expected financial or strategic benefits of an acquisition or have other adverse effects on our current business and operations;
the possible loss or reduction in value of acquired businesses;
the possibility that future acquisitions may present new complexities in deal structure, related complex accounting and coordination with new partners, particularly in light of our desire to maintain our qualification for taxation as a REIT;

the possibility that we may not be able to prepare and issue our financial statements and other public filings in a timely and accurate manner, and/or maintain an effective control environment, due to the strain on the finance organization when multiple acquisitions and integrations are occurring at the same time;
the possibility that future acquisitions may trigger property tax reassessments resulting in a substantial increase to our property taxes beyond that which we anticipated;
the possibility that future acquisitions may be in geographies and regulatory environments to which we are unaccustomed;unaccustomed and we may become subject to complex requirements and risks with which we have limited experience;
the possibility that carriers may find it cost-prohibitive or impractical to bring fiber and networks into a new IBX data center;
the possibility of litigation or other claims in connection with, or as a result of, an acquisition, including claims from terminated employees, customers, former stockholders or other third parties;
the possibility that asset divestments may be required in order to obtain regulatory clearance for a transaction; and
the possibility of pre-existing undisclosed liabilities, including, but not limited to, lease or landlord related liability, environmental liability or asbestos liability, for which insurance coverage may be insufficient or unavailable, or other issues not discovered in the diligence process; and
the possibility that we receive limited or incorrect information about the acquired business in the diligence process. For example, we sometimes do not receive all of the customer contracts associated with our acquisitions in the diligence process, which affects our visibility into customer termination rights and could expose us to additional liabilities.
The occurrence of any of these risks could have a material adverse effect on our business, results of operations, financial condition or cash flows. If an acquisition does not proceed or is materially delayed for any reason, the price of our common stock may be adversely impacted and we will not recognize the anticipated benefits of the acquisition.
We cannot assure that the price of any future acquisitions of IBX data centers will be similar to prior IBX data center acquisitions. In fact, we expect costs required to build or render new IBX data centers operational to increase in the future. If our revenue does not keep pace with these potential acquisition and expansion costs, we may not be able to maintain our current or expected margins as we absorb these additional expenses. There is no assurance we would successfully overcome these risks, or any other problems encountered with these acquisitions.
Our substantial debt could adversely affect our cash flows and limit our flexibility to raise additional capital.
We have a significant amount of debt and may need to incur additional debt to support our growth. Additional debt may also be incurred to fund future acquisitions, any future special distributions, regular distributions or the other cash outlays associated with maintaining our qualification for taxation as a REIT. As of December 31, 2015,2018, our total indebtedness (gross of debt issuance cost, debt discount, and debt premium) was approximately $6.5$11.4 billion, our stockholders’stockholders' equity was $2.7$7.2 billion and our cash, cash equivalents, and investments totaled $2.2$0.6 billion. In addition, as of December 31, 2015,2018, we had approximately $1.1$1.9 billion of additional liquidity available to us from our $1.5$2.0 billion revolving credit facility and approximately $700 million of additional liquidity available to us from our undrawn Term Loan B (as defined below) commitments as part of an approximately $2.7 billion senior credit facility agreement entered into with a group of lenders, and approximately $8.7 million undrawn from the Bridge Term Loan Agreement (as defined below) entered into to fund the Bit-isle acquisition.facility. Some of our debt contains covenants which may limit our operating flexibility. In addition to our substantial debt, we lease a majority of our IBX data centers and certain equipment under non-cancellable lease agreements, the majoritysome of which are accounted for as operating leases. As of December 31, 2015,2018, our total minimum operating lease commitments under those lease agreements, excluding potential lease renewals, was approximately $1.2$2.0 billion, which represents off-balance sheet commitments.
Our substantial amount of debt and related covenants, and our off-balance sheet commitments, could have important consequences. For example, they could:
require us to dedicate a substantial portion of our cash flow from operations to make interest and principal payments on our debt and in respect of other off-balance sheet arrangements, reducing the availability of our cash flow to fund future capital expenditures, working capital, execution of our expansion strategy and other general corporate requirements;
increase the likelihood of negative outlook from our credit rating agencies;
make it more difficult for us to satisfy our obligations under our various debt instruments;

20


increase our cost of borrowing and even limit our ability to access additional debt to fund future growth;
increase our vulnerability to general adverse economic and industry conditions and adverse changes in governmental regulations;
limit our flexibility in planning for, or reacting to, changes in our business and industry, which may place us at a competitive disadvantage compared with our competitors;
limit our operating flexibility through covenants with which we must comply, such as limiting our ability to repurchase shares of our common stock;

limit our ability to borrow additional funds, even when necessary to maintain adequate liquidity, which would also limit our ability to further expand our business; and
make us more vulnerable to increases in interest rates because of the variable interest rates on some of our borrowings to the extent we have not entirely hedged such variable rate debt.
The occurrence of any of the foregoing factors could have a material adverse effect on our business, results of operations and financial condition. In addition, the performance of our stock price may trigger events that would require the write-off of a significant portion of our debt issuance costs related to our convertible debt, which may have a material adverse effect on our results of operations.
We may also need to refinance a portion of our outstanding debt as it matures. There is a risk that we may not be able to refinance existing debt or that the terms of any refinancing may not be as favorable as the terms of our existing debt. Furthermore, if prevailing interest rates or other factors at the time of refinancing result in higher interest rates upon refinancing, then the interest expense relating to that refinanced indebtedness would increase. These risks could materially adversely affect our financial condition, cash flows and results of operations.
Adverse global economic conditions and credit market uncertainty could adversely impact our business and financial condition.
Adverse global economic conditions continue and uncertain conditions in the credit markets have created, and in the future may create, uncertainty and unpredictability and add risk to our future outlook. An uncertain global economy could also result in churn in our customer base, reductions in revenues from our offerings, longer sales cycles, slower adoption of new technologies and increased price competition, adversely affecting our liquidity. The uncertain economic environment could also have an impact on our foreign exchange forward contracts if our counterparties’counterparties' credit deteriorates or they are otherwise unable to perform their obligations. Finally, our ability to access the capital markets may be severely restricted at a time when we would like, or need, to do so which could have an impact on our flexibility to pursue additional expansion opportunities and maintain our desired level of revenue growth in the future.
If we cannot effectively manage our international operations, and successfully implement our international expansion plans, or comply with evolving laws and regulations, our revenues may not increase, and our business and results of operations would be harmed.
For the years ended December 31, 2018, 2017 and 2016, we recognized approximately 55%, 55% and 57%, respectively, of our revenues outside the U.S. We currently operate outside of the U.S. in Canada, Brazil, Colombia, EMEA and Asia-Pacific.
To date, the network neutrality of our IBX data centers and the variety of networks available to our customers has often been a competitive advantage for us. In certain of our acquired IBX data centers in the Asia-Pacific region, the limited number of carriers available reduces that advantage. As a result, we may need to adapt our key revenue-generating offerings and pricing to be competitive in those markets. In addition, we are currently undergoing expansions or evaluating expansion opportunities outside of the U.S. Undertaking and managing expansions in foreign jurisdictions may present unanticipated challenges to us.
Our international operations are generally subject to a number of additional risks, including:
the costs of customizing IBX data centers for foreign countries;
protectionist laws and business practices favoring local competition;
greater difficulty or delay in accounts receivable collection;
difficulties in staffing and managing foreign operations, including negotiating with foreign labor unions or workers' councils;
difficulties in managing across cultures and in foreign languages;
political and economic instability;
fluctuations in currency exchange rates;
difficulties in repatriating funds from certain countries;
our ability to obtain, transfer or maintain licenses required by governmental entities with respect to our business;
unexpected changes in regulatory, tax and political environments such as the United Kingdom's pending withdrawal from the European Union ("Brexit");
our ability to secure and maintain the necessary physical and telecommunications infrastructure;
compliance with anti-bribery and corruption laws;
compliance with economic and trade sanctions enforced by the Office of Foreign Assets Control of the U.S. Department of Treasury; and

compliance with evolving governmental regulation with which we have little experience.
Geo-political events, such as Brexit, may increase the likelihood of the listed risks to occur. With respect to Brexit, it is possible that the level of economic activity in the United Kingdom and the rest of Europe will be adversely impacted and that we will face increased regulatory and legal complexities in these regions which could have an adverse impact on our business and employees in EMEA and could adversely affect our financial condition and results of operations. In addition, compliance with international and U.S. laws and regulations that apply to our international operations increases our cost of doing business in foreign jurisdictions. These laws and regulations include the General Data Protection Regulation (GDPR) and other data privacy requirements, labor relations laws, tax laws, anti-competition regulations, import and trade restrictions, export requirements, economic and trade sanctions, U.S. laws such as the Foreign Corrupt Practices Act and local laws which also prohibit corrupt payments to governmental officials. Violations of these laws and regulations could result in fines, criminal sanctions against us, our officers or our employees, and prohibitions on the conduct of our business. Any such violations could include prohibitions on our ability to offer our offerings in one or more countries, could delay or prevent potential acquisitions, and could also materially damage our reputation, our brand, our international expansion efforts, our ability to attract and retain employees, our business and operating results. Our success depends, in part, on our ability to anticipate and address these risks and manage these difficulties.
Economic and political uncertainty in developing markets could adversely affect our revenue and earnings.
We conduct business and are contemplating expansion in developing markets with economies and governments that tend to be more volatile than those in the U.S. and Western Europe. The risk of doing business in developing markets such as Brazil, China, Colombia, India, Indonesia, Oman, Russia, Turkey, the United Arab Emirates and other economically volatile areas could adversely affect our operations and earnings. Such risks include the financial instability among customers in these regions, political instability, fraud or corruption and other non-economic factors such as irregular trade flows that need to be managed successfully with the help of the local governments. In addition, commercial laws in some developing countries can be vague, inconsistently administered and retroactively applied. If we are deemed to be not in compliance with applicable laws in developing countries where we conduct business, our prospects and business in those countries could be harmed, which could then have a material adverse impact on our results of operations and financial position. Our failure to successfully manage economic, political and other risks relating to doing business in developing countries and economically and politically volatile areas could adversely affect our business.
Terrorist activity throughout the world and military action to counter terrorism could adversely impact our business.
The continued threat of terrorist activity and other acts of war or hostility contribute to a climate of political and economic uncertainty. Due to existing or developing circumstances, we may need to incur additional costs in the future to provide enhanced security, including cyber security, which could have a material adverse effect on our business and results of operations. These circumstances may also adversely affect our ability to attract and retain customers, our ability to raise capital and the operation and maintenance of our IBX data centers.
Sales or issuances of shares of our common stock may adversely affect the market price of our common stock.
Future sales or issuances of common stock or other equity related securities may adversely affect the market price of our common stock, including any shares of our common stock issued to finance capital expenditures, finance acquisitions or repay debt. We have established an "at-the-market" stock offering program (the "ATM Program") through which we may, from time to time, issue and sell shares of our common stock to or through sales agents up to established limits. By the end of 2018, we completed sales having an aggregate gross proceeds of $750.0 million, thereby completing a previously authorized program, and subsequently received authorization for up to an additional $750.0 million. We may also seek authorization to sell additional shares of common stock under the ATM Program once we have reached the current $750.0 million limit which could lead to additional dilution for our stockholders. Please see Note 12 of the Notes to Consolidated Financial Statements in Item 8 of this Annual Report on Form 10-K for sales of our common stock under the ATM Program to date.
The market price of our stock may continue to be highly volatile, and the value of an investment in our common stock may decline.
The market price of the shares of our common stock has been and may continue to be highly volatile. General economic and market conditions, and market conditions for telecommunications and real estate investment trust stocks in general, may affect the market price of our common stock.
Announcements by us or others, or speculations about our future plans, may also have a significant impact on the market price of our common stock. These may relate to:
our operating results or forecasts;

new issuances of equity, debt or convertible debt by us;us, including issuances through our ATM Program;
increases in market interest rates and changes in other general market and economic conditions, including inflationary concerns;
changes to our capital allocation, tax planning or business strategy;
our qualification for taxation as a REIT and our declaration of distributions to our stockholders;
a stock repurchase program;changes in U.S. or foreign tax laws;
changes in management or key personnel;
developments in our relationships with corporate customers;
announcements by our customers or competitors;

21


changes in regulatory policy or interpretation;
governmental investigations;
changes in the ratings of our debt or stock by rating agencies or securities analysts;
our purchase or development of real estate and/or additional IBX data centers;
our acquisitions of complementary businesses; or
the operational performance of our IBX data centers.
The stock market has from time to time experienced extreme price and volume fluctuations, which have particularly affected the market prices for telecommunications companies, and which have often been unrelated to their operating performance. These broad market fluctuations may adversely affect the market price of our common stock. One of the factors that investors may consider in deciding whether to buy or sell our common stock is our distribution rate as a percentage of our stock price relative to market interest rates. If market interest rates increase, prospective investors may demand a higher distribution rate or seek alternative investments paying higher dividends or interest. As a result, interest rate fluctuations and conditions in the capital markets may affect the market value of our common stock. Furthermore, companies that have experienced volatility in the market price of their stock have been subject to securities class action litigation. We may be the target of this type of litigation in the future. Securities litigation against us could result in substantial costs and/or damages, and divert management’smanagement's attention from other business concerns, which could seriously harm our business.
If we are not able to generate sufficient operating cash flows or obtain external financing, our ability to fund incremental expansion plans may be limited.
Our capital expenditures, together with ongoing operating expenses, obligations to service our debt and the cash outlays associated with our REIT distribution requirements, are, and will continue to be, a substantial burden on our cash flow and may decrease our cash balances. Additional debt or equity financing may not be available when needed or, if available, may not be available on satisfactory terms. Our inability to obtain additional debt and/or equity financing or to generate sufficient cash from operations may require us to prioritize projects or curtail capital expenditures which could adversely affect our results of operations.
Fluctuations in foreign currency exchange rates in the markets in which we operate internationally could harm our results of operations.
We may experience gains and losses resulting from fluctuations in foreign currency exchange rates. To date, the majority of our revenues and costs are denominated in U.S. dollars; however, the majority of revenues and costs in our international operations are denominated in foreign currencies. Where our prices are denominated in U.S. dollars, our sales and revenues could be adversely affected by declines in foreign currencies relative to the U.S. dollar, thereby making our offerings more expensive in local currencies. We are also exposed to risks resulting from fluctuations in foreign currency exchange rates in connection with our international operations. To the extent we are paying contractors in foreign currencies, our operations could cost more than anticipated as a result of declines in the U.S. dollar relative to foreign currencies. In addition, fluctuating foreign currency exchange rates have a direct impact on how our international results of operations translate into U.S. dollars.
Although we currently undertake, and may decide in the future to further undertake, foreign exchange hedging transactions to reduce foreign currency transaction exposure, we do not currently intend to eliminate all foreign currency transaction exposure. In addition, REIT compliance rules may restrict our ability to enter into hedging transactions. Therefore, any weakness of the U.S. dollar may have a positive impact on our consolidated results of operations because the currencies in the foreign countries in which we operate may translate into more U.S. dollars. However, if the U.S. dollar strengthens relative to the currencies of the foreign countries in which we operate, our consolidated financial position and results of operations may be negatively impacted as amounts in foreign currencies will generally translate into fewer U.S. dollars. For additional information on foreign currency risk,risks, refer to our discussion of foreign currency risk in “Quantitative"Quantitative and Qualitative Disclosures About Market Risk”Risk" included in Item 7A of this Annual Report on Form 10-K.

Our derivative transactions expose us to counterparty credit risk.
Our derivative transactions expose us to risk of financial loss if a counterparty fails to perform under a derivative contract. Disruptions in the financial markets could lead to sudden decreases in a counterparty's liquidity, which could make them unable to perform under the terms of their derivative contract and we may not be able to realize the benefit of the derivative contract.
Changes in U.S. or foreign tax laws, regulations, or interpretations thereof, including changes to tax rates, may adversely affect our financial statements and cash taxes.
We are a U.S. company with global subsidiaries and are subject to income taxes in the U.S. (although currently limited due to our taxation as a REIT) and many foreign jurisdictions. Significant judgment is required in determining our worldwide provision for income taxes. The U.S. government has also recently changed tax laws in the U.S. and the governments of many of the countries in which we operate are actively discussing changes to foreign tax laws. Although we believe that we have adequately assessed and accounted for our potential tax liabilities, and that our tax estimates are reasonable, there can be no certainty that additional taxes will not be due upon audit of our tax returns or as a result of further changes to the tax laws and interpretations thereof. The U.S. Congress as well as the governments of many of the countries in which we operate are actively discussing changes to the corporate recognition and taxation of worldwide income. The

22


nature and timing of any future changes to each jurisdiction’sjurisdiction's tax laws and the impact on our future tax liabilities cannot be predicted with any accuracy but could materially and adversely impact our results of operations and financial position or cash flows.
We may be vulnerable to security breaches which could disrupt our operations and have a material adverse effect on our financial performance and operating results.
We face risks associated with unauthorized access to our computer systems, loss or destruction of data, computer viruses, malware, distributed denial-of-service attacks or other malicious activities. These threats may result from human error, equipment failure or fraud or malice on the part of employees or third parties. A party who is able to compromise the security measures on our networks or the security of our infrastructure could misappropriate either our proprietary information or the personal information of our customers or our employees, or cause interruptions or malfunctions in our operations or our customers' operations. As we provide assurances to our customers that we provide a high level of security, such a compromise could be particularly harmful to our brand and reputation. We may be required to expend significant capital and resources to protect against such threats or to alleviate problems caused by breaches in security. As techniques used to breach security change frequently and are generally not recognized until launched against a target, we may not be able to promptly detect that a cyber breach has occurred, or implement security measures in a timely manner or, if and when implemented, we may not be able to determine the extent to which these measures could be circumvented. Any breaches that may occur could expose us to increased risk of lawsuits, regulatory penalties, loss of existing or potential customers, damage relating to loss of proprietary information, harm to our reputation and increases in our security costs, which could have a material adverse effect on our financial performance and operating results. We maintain insurance coverage for cyber risks, but such coverage may be unavailable or insufficient to cover our losses.    
We offer professional services to our customers where we consult on data center solutions and assist with implementations. We also offer managed services in certain of our foreign jurisdictions outside of the U.S. where we manage the data center infrastructure for our customers. The access to our clients' networks and data, which is gained from these services, creates some risk that our clients' networks or data will be improperly accessed. We may also design our clients' cloud storage systems in such a way that exposes our clients to increased risk of data breach.  If Equinix were held to be responsible for any such a breach, it could result in a significant loss to Equinix, including damage to Equinix's client relationships, harm to our brand and reputation, and legal liability.
We are continuing to invest in our expansion efforts but may not have sufficient customer demand in the future to realize expected returns on these investments.
We are considering the acquisition or lease of additional properties and the construction of new IBX data centers beyond those expansion projects already announced. We will be required to commit substantial operational and financial resources to these IBX data centers, generally 12 to 18 months in advance of securing customer contracts, and we may not have sufficient customer demand in those markets to support these centers once they are built. In addition, unanticipated technological changes could affect customer requirements for data centers, and we may not have built such requirements into our new IBX data centers. Either of these contingencies, if they were to occur, could make it difficult for us to realize expected or reasonable returns on these investments.
Our offerings have a long sales cycle that may harm our revenuesrevenue and operating results.
A customer’scustomer's decision to purchase our offerings typically involves a significant commitment of resources. In addition, some customers will be reluctant to commit to locating in our IBX data centers until they are confident that the IBX data center has adequate carrier connections. As a result, we have a long sales cycle. Furthermore, we may devote significant time and resources into pursuing a particular sale or customer that does not result in revenue.revenues. We have also significantly expanded our sales force in recent years, and it will take time for these new hires to become fully productive.

Delays due to the length of our sales cycle may materially and adversely affect our revenues and operating results, which could harm our ability to meet our forecasts and cause volatility in our stock price.
Any failure of our physical infrastructure or offerings, or damage to customer infrastructure within our IBX data centers, could lead to significant costs and disruptions that could reduce our revenue and harm our business reputation and financial results.
Our business depends on providing customers with highly reliable solutions. We must safehouse our customers’customers' infrastructure and equipment located in our IBX data centers.centers and ensure our IBX data centers and non-IBX offices remain operational. We own certain of our IBX data centers, but others are leased by us, and we rely on the landlord for basic maintenance of our leased IBX data centers.centers and office buildings. If such landlord has not maintained a leased property sufficiently, we may be forced into an early exit from the center which could be disruptive to our business. Furthermore, we continue to acquire IBX data centers not built by us. If we discover that these IBX data centersbuildings and their infrastructure assets are not in the condition we expected when they were acquired, we may be required to incur substantial additional costs to repair or upgrade the centers.
The offerings we provide in each of ourOur office buildings and IBX data centers are subject to failure resulting from, and infrastructure within such IBX data centers is at risk from, numerous factors, including:
human error;
equipment failure;
physical, electronic and cybersecuritycyber security breaches;
fire, earthquake, hurricane, flood, tornado and other natural disasters;
extreme temperatures;
water damage;
fiber cuts;
power loss;
terrorist acts;
sabotage and vandalism; and
failure of business partners who provide our resale products.
Problems at one or more of our IBX data centers, whether or not within our control, could result in service interruptions or significant equipment damage. We have service level commitment obligations to certain of our customers. As a result, service interruptions or significant equipment damage in our IBX data centers could result in difficulty maintaining service level

23


commitments to these customers and potential claims related to such failures. Because our IBX data centers are critical to many of our customers’customers' businesses, service interruptions or significant equipment damage in our IBX data centers could also result in lost profits or other indirect or consequential damages to our customers. We cannot guarantee that a court would enforce any contractual limitations on our liability in the event that one of our customers brings a lawsuit against us as a result of a problem at one of our IBX data centers and we may decide to reach settlements with affected customers irrespective of any such contractual limitations. Any such settlement may result in a reduction of revenue under U.S. generally accepted accounting principles ("GAAP"). In addition, any loss of service, equipment damage or inability to meet our service level commitment obligations could reduce the confidence of our customers and could consequently impair our ability to obtain and retain customers, which would adversely affect both our ability to generate revenues and our operating results.
Furthermore, we are dependent upon Internetinternet service providers, telecommunications carriers and other website operators in the Americas, Asia-Pacific and EMEA regions and elsewhere, some of which have experienced significant system failures and electrical outages in the past. Our customers may in the future experience difficulties due to system failures unrelated to our systems and offerings. If, for any reason, these providers fail to provide the required services, our business, financial condition and results of operations could be materially and adversely impacted.
We are currently making significant investments in our back office information technology systems including those surrounding the customer experienceand processes.  Difficulties from initial quote to customer billing, and upgrading our worldwide financial application suite. Difficulties, distractions or disruptions to these efforts may interrupt our normal operations and adversely affect our business and operating results.
CommencingWe have been investing heavily in 2012, we began a significant project to overhaul our back office information technology systems and processes for a number of years and expect such investment to continue for the foreseeable future in support of our pursuit of global, scalable solutions across all geographies and functions that supportwe operate in.  These continuing investments include: 1) ongoing improvements to the customer experience from initial quote to customer billing and our revenue recognition process. Additionally, commencing in 2013, we began to devote significant resources to the upgradeprocess; 2) integration of recently-acquired operations onto our worldwide financial application suite from Oracle’s version 11i to R12. While significant milestones have been achieved on both projects, both projects have continued into 2016. Oracle has already begun to discontinue its support for our current business application suite. While the Oracle financial application suite implementation was largely completed in July 2014various information technology systems; and the initial3) implementation of the systemsnew tools and technologies to either further streamline

and automate processes, such as our fixed asset procure to disposal process, or to support our billingcompliance with evolving U.S. GAAP, such as the new revenue accounting, derivatives and revenue process was completed in August 2014, work continues on our back office systemshedging and their global implementation, including upgrades and developing new functionality.leasing standards.  As a result of that discontinued support and our continued work on these projects, we may experience difficulties with our systems, management distraction and significant business disruptions. DifficultiesFor example, difficulties with our systems may interrupt our ability to accept and deliver customer orders and may adversely impact our overall financial operations, including our accounts payable, accounts receivables, general ledger, fixed assets, revenue recognition, close processes, internal financial controls and our ability to otherwise run and track our business. We may need to expend significant attention, time and resources to correct problems or find alternative sources for performing these functions. All of these changes to our financial systems also create an increased risk of deficiencies in our internal controls over financial reporting until such systems are stabilized. Such significant investments in our back office systems may take longer to complete and cost more than originally planned. In addition, we may not realize the full benefits we hoped to achieve and there is a risk of an impairment charge if we decide that portions of these projects will not ultimately benefit the company or are de-scoped. Finally, the collective impact of these changes to our business has placed significant demands on impacted employees across multiple functions, increasing the risk of errors and control deficiencies in our financial statements, distraction from the effective operation of our business and difficulty in attracting and retaining employees. Any such difficultydifficulties or disruptiondisruptions may adversely affect our business and operating results.
Inadequate or inaccurate external and internal information, including budget and planning data, could lead to inaccurate financial forecasts and inappropriate financial decisions.
Our financial forecasts are dependent on estimates and assumptions regarding budget and planning data, market growth, foreign exchange rates, our ability to remain qualified for taxation as a REIT, and our ability to generate sufficient cash flow to reinvest in the business, fund internal growth, make acquisitions, pay dividends and meet our debt obligations. Our financial projections are based on historical experience and on various other assumptions that our management believes to be reasonable under the circumstances and at the time they are made. However, if our external and internal information is inadequate, our actual results may differ materially from our forecasts and cause us to make inappropriate financial decisions. Any material variation between our financial forecasts and our actual results may also adversely affect our future profitability, stock price and stockholder confidence.
The level of insurance coverage that we purchase may prove to be inadequate.
We carry liability, property, business interruption and other insurance policies to cover insurable risks to our company. We select the types of insurance, the limits and the deductibles based on our specific risk profile, the cost of the insurance coverage versus its perceived benefit and general industry standards. Our insurance policies contain industry standard exclusions for events such as war and nuclear reaction. We purchase minimal levels of earthquake insurance for certain of our IBX data centers, but for most of our data centers, including many in California, we have elected to self-insure. The earthquake and flood insurance that we do purchase would be subject to high deductibles. Any of the limits of insurance that we purchase, including those for cyber risks, could prove to be inadequate, which could materially and adversely impact our business, financial condition and results of operations.
Our construction of additional new IBX data centers or IBX data center expansions could involve significant risks to our business.
In order to sustain our growth in certain of our existing and new markets, we mustmay have to expand an existing data center, lease a new facility or acquire suitable land, with or without structures, to build new IBX data centers from the ground up. Expansions or new builds are currently underway, or being contemplated, in many of our markets. AnyThese construction projects expose us to many risks which could have an adverse effect on our operating results and financial condition. Some of the risks associated with these projects include:
construction delays;
lack of availability and delays for data center equipment, including items such as generators and switchgear;
unexpected budget changes;
increased prices for building supplies, raw materials and data center equipment;
labor availability, labor disputes and work stoppages with contractors, subcontractors and other third parties;
unanticipated environmental issues and geological problems; and
delays related to permitting from public agencies and utility companies.

Additionally, all construction requiresrelated projects require us to carefully select and rely on the experience of one or more designers, general contractors, and associated subcontractors during the design and construction process. Should a designer, general contractor or significant subcontractor experience financial problems or other problems

24


during the design or construction process, we could experience significant delays, increased costs to complete the project and/or other negative impacts to our expected returns.
Site selection is also a critical factor in our expansion plans. There may not be suitable properties available in our markets with the necessary combination of high power capacity and fiber connectivity, or selection may be limited. Thus, while we may prefer to locate new IBX data centers adjacent to our existing locations, it may not always be possible. In the event we decide to build new IBX data centers separate from our existing IBX data centers, we may provide interconnection solutions to connect these two centers. Should these solutions not provide the necessary reliability to sustain connection, this could result in lower interconnection revenue and lower margins and could have a negative impact on customer retention over time.
Environmental regulations may impose upon us new or unexpected costs.
We are subject to various federal, state, local and international environmental and health and safety laws and regulations, including those relating to the generation, storage, handling and disposal of hazardous substances and wastes. Certain of these laws and regulations also impose joint and several liability, without regard to fault, for investigation and cleanup costs on current and former owners and operators of real property and persons who have disposed of or released hazardous substances into the environment. Our operations involve the use of hazardous substances and materials such as petroleum fuel for emergency generators, as well as batteries, cleaning solutions and other materials. In addition, we lease, own or operate real property at which hazardous substances and regulated materials have been used in the past. At some of our locations, hazardous substances or regulated materials are known to be present in soil or groundwater, and there may be additional unknown hazardous substances or regulated materials present at sites we own, operate or lease. At some of our locations, there are land use restrictions in place relating to earlier environmental cleanups that do not materially limit our use of the sites. To the extent any hazardous substances or any other substance or material must be cleaned up or removed from our property, we may be responsible under applicable laws, regulations or leases for the removal or cleanup of such substances or materials, the cost of which could be substantial.
Electricity is a material cost in connection with our business, and an increase in the cost of electricity could adversely affect us. The generators that provide electricity to our facilities are subject to environmental laws, regulations and permit requirements that are subject to material change, which could result in increases in generators' compliance costs that may be passed through to us. Regulations recently promulgated by the U.S. EPA could limit air emissions from power plants, restrict discharges of cooling water, and otherwise impose new operational restraints on conventional power plants that could increase costs of electricity. In addition, we are directly subject to environmental, health and safety laws regulating air emissions, storm water management and other issues arising in our business. For example, our emergency generators are subject to state and federal regulations governing air pollutants, which could limit the operation of those generators or require the installation of new pollution control technologies. While these obligationsenvironmental regulations do not normally impose material costs upon our operations, unexpected events, equipment malfunctions, and human error and changes in law or regulations, among other factors, can lead to violations of environmental laws, regulations or permits.permits, and to additional unexpected operational limitations or costs.
Regulation of greenhouse gas (“GHG”("GHG") emissions could increase the cost of electricity by reducing amounts of electricity generated from fossil fuels, by requiring the use of more expensive generating methods or by imposing taxes or fees upon electricity generation or use. ElectricityThe U.S. EPA finalized a regulation in October 2015, called the "Clean Power Plan," that was intended to reduce GHG emissions from existing fossil fuel-fired power plants by 32 percent from 2005 levels by 2030. The Clean Power Plan was challenged in court and the rule has not been implemented because litigation is ongoing. In August 2018, the U.S. EPA issued a material costproposed rule that would replace the Clean Power Plan with the "Affordable Clean Energy" rule. Under the Affordable Clean Energy rule, coal-fired power plants will be required to make efficiency improvements to reduce their GHG emissions.  The U.S. EPA expects to finalize the Affordable Clean Energy rule in connection with2019, but the rule will likely be challenged in court, which may delay its implementation. While we do not expect these regulatory developments to materially increase our business, and an increase in the costcosts of electricity, whether from regulationthe costs remain difficult to predict or estimate.
State regulations also have the potential to increase our costs of GHGs or otherwise, could adversely affect us. GHG reduction legislation exists in Europe, and in several of the states in the U.S., and there is a potential for new or additional legislation in the U.S. and other countries in which we operate.obtaining electricity. Certain states, like California, already regulatealso have issued or may enact environmental regulations that could materially affect our facilities and electricity costs. California has limited GHG emissions from new and existing state-regulated facilitiesconventional power plants by imposing regulatory caps on allowances and by selling or auctioning the rights to such emissions. Theseemission allowances. Washington, Oregon and Massachusetts have issued regulations to implement similar carbon cap and trade programs, and other states are considering proposals to limit carbon emissions through cap and trade programs, carbon pricing programs and other mechanisms. Some states limit carbon emissions through the Regional Greenhouse Gas Initiative ("RGGI") cap and trade program. State programs have not had a material adverse effect on our electricity costs to date, but due to the market-driven nature of some of the programs, they could do sohave a material adverse effect on electricity costs in the future. Such laws and regulations are also subject to change at any time.

Aside from regulatory requirements, we have separately undertaken efforts to procure energy from renewable energy projects in order to support new renewables development. The U.S. EPA published regulations in October 2015, calledcosts of procuring such energy may exceed the “Clean Power Plan,” that is intended to reduce GHG emissionscosts of procuring electricity from existing fossil fuel-fired power plants by 32 percent from 2005 levels by 2030. Under the rule, each state is requiredsources, such as existing utilities or electric service provided through conventional grids. These efforts to develop a plan to reduce state-wide carbon dioxide emissions to meet a specified emissions target set by EPA for that state. If implemented, the Clean Power Plan could impose new emissions trading or credit programs, or other requirements, that could indirectlysupport and enhance renewable electricity generation may increase the average costour costs of electricity in states in which we operate.
New laws in the U.S. and other countries may arise as a result of international agreements. In November 2014, the United States and China announced a climate change agreementabove those that established goals for reducing GHG emissions from both countries, including the prevention of increases in GHG emissions from China after 2030. In order for China to meet this commitment, China may impose limitations on fossil fuel generation or costs upon electricity, similar to those imposed in the U.S. and elsewhere.
On December 12, 2015, the Obama Administration reached agreement in Paris with a majority of 194 attending nations concerning a voluntary program for limiting GHGs. This agreement, known as the Paris Climate Accord (the “Accord”) would, if it becomes effective, require signatory countries to establish GHG reduction goals and report on their implementation of programs to achieve such goals. The Accord would be open for signature for one year commencing in April 2016, and would become effective commencing in 2020 if at least 55 countries representing at least 55%incurred through procurement of aggregate, global GHG emissions sign. The U.S. has announced a commitment in support of the Accord to achieve reductions of GHG emissions to levels that are 26-28 percent below 2005 levels by 2025.

Compliance with international agreements, such as the agreement with China and the Accord, could require new national legislation to be adopted in the U.S. or other signatory countries. In this case, in the U.S., if the Clean Power Plan is implemented in the form prescribed by EPA as a final regulation, it may substantially achieve international GHG emissions reduction commitments by the U.S. government. Accordingly, there may be no new legislation or regulation would be required to implement the Accord, assuming that the Clean Power Plan is implemented as set forth in the regulation. Nevertheless, laws or regulations may change over time. To the extent any environmental laws enacted or regulations impose new or unexpected costs, our business, results of operations or financial condition may be adversely affected.conventional electricity from existing sources.
If we are unable to recruit or retain key executives and qualified personnel, our business could be harmed.
In connection with the evolving needs of our customers and our business, and under the direction of our new chief executive officer, we have undertaken a review of our organizational architecture. To the extent that we make changes to our organizational architecture as a result of that review, there can be no assurances that the changes won't result in attrition, or that any changes will result in increased organizational effectiveness. We must also continue to identify, hire, train and retain IT professionals, technical engineers, operations employees, and sales, marketing, finance and senior managementkey personnel who maintain relationships with our customers and who can provide the technical, strategic and marketing skills required for our company to grow.company's growth. There is a shortage of qualified personnel in these fields, and we compete with other companies for the limited pool of talent.
The failure to recruit and retain necessary key executives and personnel including, but not limited to, members of our executive team, could cause disruption, harm our business and hamper our ability to grow our company.
We may not be able to compete successfully against current and future competitors.
The global multi-tenant data center market is highly fragmented. It is estimated that Equinix is one of more than 1,200 companies that provide these offerings around the world. Equinix competes with these firms which vary in terms of their data center offerings. We must continue to evolve our product strategy and be able to differentiate our IBX data centers and product offerings from those of our competitors. In addition to competing
As our customers evolve their IT strategies, we must remain flexible and evolve along with other neutral colocation providers, we compete with traditional colocation providers, including telecommunications companies, carriers, internet service providers, managed services providersnew technologies and large REITs who also operateindustry and market shifts. Ineffective planning and execution in our marketcloud and product development strategies may enjoy a costcause difficulty in sustaining competitive advantage in providing offerings similarour products and services.
We are also in discussions with a targeted set of hyperscale customers to those provideddevelop capacity to serve their larger footprint needs by leveraging existing capacity and dedicated hyperscale builds. We have announced our IBX data centers. We may experience competition from our landlords which could also reduce the amount of space availableintention to usseek a joint venture partner for expansion in the future. Rather than leasing available space in our buildings to large single tenants, they may decide to convert the space instead to smaller square foot units designed for multi-tenant colocation use, blurring the line between retail and wholesale space. We may also face competition from existing competitors or new entrants to the market seeking to replicate our global IBX data center concept by building or acquiring data centers, offering colocation on neutral terms or by replicating our strategy and messaging. Finally, customers may also decide it is cost-effective for them to build out their own data centers. Once customers have an established data center footprint, either through a relationship with onecertain of our competitorshyperscale builds. There can be no assurances that we find such partner or through in-sourcing, it may be extremely difficultthat we are able to convince them to relocate to our IBX data centers.successfully meet the needs of these customers.
Some of our competitors may adopt aggressive pricing policies, especially if they are not highly leveraged or have lower return thresholds than we do. As a result, we may suffer from pricing pressure that would adversely affect our ability to generate revenues. Some of these competitors may also provide our target customers with additional benefits, including bundled communication services or cloud services, and may do so in a manner that is more attractive to our potential customers than obtaining space in our IBX data centers. Similarly, with growing acceptance of cloud-based technologies, Equinix iswe are at risk of losing customers that may decide to fully leverage cloud infrastructure offerings instead of managing their own. Competitors could also operate more successfully or form alliances to acquire significant market share.
Failure to compete successfully may materially adversely affect our financial condition, cash flows and results of operations.
Our business could be harmed by prolonged power outages or shortages, increased costs of energy or general lack of availability of electrical resources.
Our IBX data centers are susceptible to regional costs of power, power shortages, planned or unplanned power outages and limitations, especially internationally, on the availability of adequate power resources.
Power outages, such asincluding, but not limited to those relating to large storms, earthquakes, fires and tsunamis, could harm our customers and our business. We attempt to limit our exposure to system downtime by using backup generators and power supplies; however, we may not be able to limit our exposure entirely even with these protections in place. Some of our IBXsIBX data centers are located in leased buildings where, depending upon the lease requirements and number of tenants involved, we may or may not control some or all of the infrastructure including generators and fuel tanks. As a result, in the event of a power outage, we may be dependent upon the landlord, as well as the utility company, to restore the power.
In addition, global fluctuations in the price of power can increase the cost of energy, and although contractual price increase clauses exist in the majority of our customer agreements, we may not always choose to pass these increased costs on to our customers.

26


In each of our markets, we rely on third parties to provide a sufficient amount of power for current and future customers. At the same time, power and cooling requirements are growing on a per unit basis. As a result, some customers are consuming an increasing amount of power per cabinet. We generally do not control the amount of power our customers draw from their installed circuits. This means that we could face power limitations in our IBX data centers. This could have a negative impact on the effective available capacity of a given center and limit our ability to grow our business, which could have a negative impact on our financial performance, operating results and cash flows.
We may also have difficulty obtaining sufficient power capacity for potential expansion sites in new or existing markets. We may experience significant delays and substantial increased costs demanded by the utilities to provide the level of electrical service required by our current IBX data center designs.
If our internal controls are found to be ineffective, our financial results or our stock price may be adversely affected.
Our most recent evaluationOn January 29, 2019, Pacific Gas and Electric Company (“PG&E”), the public utility that serves the area in which some of our controls resultedfacilities are located, filed for bankruptcy protection in our conclusionthe United States Bankruptcy Court for the Northern District of California, San Francisco (“Bankruptcy Court”). PG&E announced that asit filed for bankruptcy to facilitate the resolution of December 31, 2015,liabilities in complianceconnection with Section 404the 2017 and 2018 Northern California wildfires. It is possible that, during its bankruptcy, PG&E may seek permission from the Bankruptcy Court to reject, i.e., breach, certain burdensome executory contracts, including high-priced power purchase agreements and other agreements under which PG&E procures electricity for distribution to customers like us. It is not certain that PG&E will be able to obtain such relief. Just before the bankruptcy filing, the Federal Energy Regulatory Commission (“FERC”) ruled that its approval is required before PG&E may reject any FERC-jurisdictional wholesale power agreements. If PG&E seeks and is allowed to reject power agreements, it is difficult to predict the consequences of any such action for us but they could potentially include procuring electricity from more expensive sources, reducing the Sarbanes-Oxley Actavailability and reliability of 2002, our internal controls over financial reporting were effective. Our ability to manage our operations and growth, through, for example, our upgrade of our worldwide financial application suite from Oracle's version 11i to R12 and our overhaul of our back office systems that support customer experience from initial quote to customer billing and our revenue recognition process, will require us to further develop our controls and reporting systems and implement or amend new or existing controls and reporting systems in those areas where the implementation is still ongoing. All of these changeselectricity supplied to our financial systems create an increased riskfacilities and relying on a larger percentage of deficiencies in our internal controls over financial reporting until such systems are stabilized. If, in the future, our internal control over financial reporting is found to be ineffective, or if a material weakness is identified in our controls over financial reporting, our financial results may be adversely affected. Investors may also lose confidence in the reliabilityelectricity generated by fossil fuels, any of our financial statements which could adversely affect our stock price.
If we cannot effectively manage our international operations, and successfully implement our international expansion plans, our revenues may not increase and our business and resultsreduce supplies of operations would be harmed.
For the years ended December 31, 2015, 2014 and 2013, we recognized approximately 49%, 49% and 46%, respectively, of our revenues outside the U.S. We currently operate outside of the U.S. in Canada, Brazil, EMEA and Asia-Pacific.
To date, the network neutrality of our IBX data centers and the variety of networkselectricity available to our customers has often been a competitive advantage for us. In certain ofoperations or increase our acquired IBX data centers in the Asia-Pacific region the limited number of carriers available reduces that advantage. As a result, we may need to adapt our key revenue-generating offerings and pricing to be competitive in those markets. In addition, we are currently undergoing expansions or evaluating expansion opportunities outside of the U.S. Undertaking and managing expansions in foreign jurisdictions may present unanticipated challenges to us.
Our international operations are generally subject to a number of additional risks, including:
the costs of customizing IBX data centers for foreign countries;
protectionist laws and business practices favoring local competition;
greater difficulty or delay in accounts receivable collection;
difficulties in staffing and managing foreign operations, including negotiating with foreign labor unions or workers’ councils;
difficulties in managing across cultures and in foreign languages;
political and economic instability;
fluctuations in currency exchange rates;
difficulties in repatriating funds from certain countries;
our ability to obtain, transfer, or maintain licenses required by governmental entities with respect to our business;
unexpected changes in regulatory, tax and political environments;
our ability to secure and maintain the necessary physical and telecommunications infrastructure;
compliance with anti-bribery and corruption laws;

27


compliance with economic and trade sanctions enforced by the Office of Foreign Assets Control of the U.S. Department of Treasury; and
compliance with evolving governmental regulation with which we have little experience.
In addition, compliance with international and U.S. laws and regulations that apply to our international operations increases our cost of doing business in foreign jurisdictions. These laws and regulations include data privacy requirements, labor relations laws, tax laws, anti-competition regulations, import and trade restrictions, export requirements, economic and trade sanctions, U.S. laws such as the Foreign Corrupt Practices Act and local laws which also prohibit corrupt payments to governmental officials. Violations of these laws and regulations could result in fines, criminal sanctions against us, our officers or our employees, and prohibitions on the conduct of our business. Any such violations could include prohibitions on our ability to offer our offerings in one or more countries, could delay or prevent potential acquisitions, and could also materially damage our reputation, our brand, our international expansion efforts, our ability to attract and retain employees, our business and our operating results. Our success depends, in part, on our ability to anticipate and address these risks and manage these difficulties.
Economic uncertainty in developing markets could adversely affect our revenue and earnings.
We conduct business and are contemplating expansion, in developing markets with economies that tend to be more volatile than those in the U.S. and Western Europe. The risk of doing business in developing markets such as Brazil, China, India, Indonesia, Russia, the United Arab Emirates and other economically volatile areas could adversely affect our operations and earnings. Such risks include the financial instability among customers in these regions, political instability, fraud or corruption and other non-economic factors such as irregular trade flows that need to be managed successfully with the help of the local governments. In addition, commercial laws in some developing countries can be vague, inconsistently administered and retroactively applied. If we are deemed not to be in compliance with applicable laws in developing countries where we conduct business, our prospects and business in those countries could be harmed, which could then have a material adverse impact on our results of operations and financial position. Our failure to successfully manage economic, political and other risks relating to doing business in developing countries and economically and politically volatile areas could adversely affect our business.electricity.
The use of high power density equipment may limit our ability to fully utilize our older IBX data centers.
Some customers have increased their use of high power density equipment, such as blade servers, in our IBX data centers which has increased the demand for power on a per cabinet basis. Because many of our IBX data centers were built a number of years ago, the current demand for power may exceed the designed electrical capacity in these centers. As power, not space, is a limiting factor in many of our IBX data centers, our ability to fully utilize those IBX data centers may be limited.impacted. The ability to increase the power capacity of an IBX data center, should we decide to, is dependent on several factors including, but not limited to, the local utility’sutility's ability to provide additional power; the length of time required to provide such power; and/or whether it is feasible to upgrade the electrical infrastructure of an IBX data center to deliver additional power to customers. Although we are currently designing and building to a higher power specification than that of many of our older IBX data centers, there is a risk that demand will continue to increase and our IBX data centers could become underutilized sooner than expected.
If our internal controls are found to be ineffective, our financial results or our stock price may be adversely affected.
Our most recent evaluation of our controls resulted in our conclusion that, as of December 31, 2018, in compliance with Section 404 of the Sarbanes-Oxley Act of 2002, our internal controls over financial reporting were effective. Our ability to manage our operations and growth, through, for example, the integration of Metronode, Infomart Dallas, Itconic, and Zenium, the adoption of new accounting principles and tax laws, and our overhaul of our back office systems that, for example, support the customer experience from initial quote to customer billing and our revenue recognition process, will require us to further develop our controls and reporting systems and implement or amend new or existing controls and reporting systems in those areas where the implementation and integration is still ongoing. All of these changes to our financial systems and the implementation and integration of acquisitions create an increased risk of deficiencies in our internal controls over financial reporting. If, in the future, our internal control over financial reporting is found to be ineffective, or if a material weakness is identified in our controls over financial reporting, our financial results may be adversely affected. Investors may also lose confidence in the reliability of our financial statements which could adversely affect our stock price.
Our operating results may fluctuate.
We have experienced fluctuations in our results of operations on a quarterly and annual basis. The fluctuations in our operating results may cause the market price of our common stock to be volatile. We may experience significant fluctuations in our operating results in the foreseeable future due to a variety of factors, including, but not limited to:
fluctuations of foreign currencies in the markets in which we operate;
the timing and magnitude of depreciation and interest expense or other expenses related to the acquisition, purchase or construction of additional IBX data centers or the upgrade of existing IBX data centers;
demand for space, power and servicessolutions at our IBX data centers;

changes in general economic conditions, such as an economic downturn, or specific market conditions in the telecommunications and Internetinternet industries, both of which may have an impact on our customer base;
charges to earnings resulting from past acquisitions due to, among other things, impairment of goodwill or intangible assets, reduction in the useful lives of intangible assets acquired, identification of additional assumed contingent liabilities or revised estimates to restructure an acquired company’scompany's operations;

28


the duration of the sales cycle for our offerings and our ability to ramp our newly-hired sales persons to full productivity within the time period we have forecasted;
restructuring charges or reversals of restructuring charges, which may be necessary due to revised sublease assumptions, changes in strategy or otherwise;
acquisitions or dispositions we may make;
the financial condition and credit risk of our customers;
the provision of customer discounts and credits;
the mix of current and proposed products and offerings and the gross margins associated with our products and offerings;
the timing required for new and future IBX data centers to open or become fully utilized;
competition in the markets in which we operate;
conditions related to international operations;
increasing repair and maintenance expenses in connection with aging IBX data centers;
lack of available capacity in our existing IBX data centers to generate new revenue or delays in opening new or acquired IBX data centers that delay our ability to generate new revenue in markets which have otherwise reached capacity;
changes in rent expense as we amend our IBX data center leases in connection with extending their lease terms when their initial lease term expiration dates approach or changes in shared operating costs in connection with our leases, which are commonly referred to as common area maintenance expenses;
the timing and magnitude of other operating expenses, including taxes, expenses related to the expansion of sales, marketing, operations and acquisitions, if any, of complementary businesses and assets;
the cost and availability of adequate public utilities, including power;
changes in employee stock-based compensation;
overall inflation;
increasing interest expense due to any increases in interest rates and/or potential additional debt financings;
changes in our tax planning strategies or failure to realize anticipated benefits from such strategies;
changes in income tax benefit or expense; and
changes in or new generally accepted accounting principles (“GAAP”) in the U.S.GAAP as periodically released by the Financial Accounting Standards Board (“FASB”("FASB").
Any of the foregoing factors, or other factors discussed elsewhere in this report, could have a material adverse effect on our business, results of operations and financial condition. Although we have experienced growth in revenues in recent quarters, this growth rate is not necessarily indicative of future operating results. Prior to 2008, we had generated net losses every fiscal year since inception. It is possible that we may not be able to generate net income on a quarterly or annual basis in the future. In addition, a relatively large portion of our expenses are fixed in the short-term, particularly with respect to lease and personnel expenses, depreciation and amortization and interest expenses. Therefore, our results of operations are particularly sensitive to fluctuations in revenues. As such, comparisons to prior reporting periods should not be relied upon as indications of our future performance. In addition, our operating results in one or more future quarters may fail to meet the expectations of securities analysts or investors.
Our days sales outstanding (DSO) of our accounts receivables have been increasing.("DSO") may be negatively impacted by process and system upgrades and acquisitions.
Although we have historically experienced a record of strong collection of our accounts receivables as evidenced by our prior DSO metrics, our DSO has increased over the past year. Our DSO was affected by the implementation of a new billing system that was introduced during the second half of 2014. While this new system is now operational in all three regions, it is not operational in all countries within each region and further enhancements to the overall system are still ongoing. While our DSO began to improve during the second half of 2015, our DSO may continue to be adverselynegatively impacted by ongoing changesprocess and system upgrades which can impact our customers' experience in the billing system,short term, together with integrating recent acquisitions into our processes and systems, which would continue tomay have a negative impact on our operating cash flows, liquidity and financial performance.

Our reported financial results may be adversely affected by changes in U.S. GAAP.
29

TableWe prepare our consolidated financial statements in conformity with U.S. GAAP. A change in these principles can have a significant effect on our reported financial position and financial results. In addition, the adoption of Contentsnew or revised accounting principles may require us to make changes to our systems, processes and controls, which could require us to make costly changes to our operational processes and accounting systems upon or following the adoption of these standards. For example, we adopted the new lease accounting standard on January 1, 2019, which requires lessees to recognize right-of-use assets and right-of-use liabilities related to operating leases. As a result, we will record significant operating lease obligations on our balance sheet and


make other changes in our financial statements, which will have a material effect on our financial statements. We are also implementing a new lease accounting tool, which may impact our accounting and reporting process. This, and other future changes to accounting rules, could have a material adverse effect on the reporting of our business, financial condition and results of operations. For additional information regarding the accounting standard updates, see "Accounting Standards Not Yet Adopted" and "Accounting Standards Adopted" sections of Note 1 of Notes to Consolidated Financial Statements in Item 8 of this Annual Report on Form 10-K.
We may incur goodwill and other intangible asset impairment charges, or impairment charges to our property, plant and equipment, which could result in a significant reduction to our earnings.
In accordance with U.S. GAAP, we are required to assess our goodwill and other intangible assets annually, or more frequently whenever events or changes in circumstances indicate potential impairment, such as changing market conditions or any changes in key assumptions. If the testing performed indicates that an asset may not be recoverable, we are required to record a non-cash impairment charge for the difference between the carrying value of the goodwill or other intangible assets and the implied fair value of the goodwill or other intangible assets in the period the determination is made.
We also periodically monitor the remaining net book values of our property, plant and equipment, periodically, including at the individual IBX data center level. Although each individual IBX data center is currently performing in lineaccordance with our expectations, the possibility that one or more IBX data centers could begin to under-perform relative to our expectations is possible and may also result in non-cash impairment charges.
These charges could be significant, which could have a material adverse effect on our business, results of operations or financial condition.
We have incurred substantial losses in the past and may incur additional losses in the future.
As of December 31, 2015,2018, our accumulated deficit was $108.2retained earnings were $889.9 million. Although we have generated net income for each fiscal year since 2008, except for the year ended December 31, 2014, we are also currently investing heavily in our future growth through the build out of multiple additional IBX data centers, andexpansions of IBX data center expansions as well ascenters and acquisitions of complementary businesses. As a result, we will incur higher depreciation and other operating expenses, as well as acquisition costs and interest expense, that may negatively impact our ability to sustain profitability in future periods unless and until these new IBX data centers generate enough revenue to exceed their operating costs and cover ourthe additional overhead needed to scale our business for this anticipated growth. The current global financial uncertainty may also impact our ability to sustain profitability if we cannot generate sufficient revenue to offset the increased costs of our recently-opened IBX data centers or IBX data centers currently under construction. In addition, costs associated with the acquisition and integration of any acquired companies, as well as the additional interest expense associated with debt financing we have undertaken to fund our growth initiatives, may also negatively impact our ability to sustain profitability. Finally, given the competitive and evolving nature of the industry in which we operate, we may not be able to sustain or increase profitability on a quarterly or annual basis.
The failure to obtain favorable terms when we renew our IBX data center leases, or the failure to renew such leases, could harm our business and results of operations.
While we own certain of our IBX data centers, others are leased under long-term arrangements with lease terms expiring at various dates through 2065. These leased centers have all been subject to significant development by us in order to convert them from, in most cases, vacant buildings or warehouses into IBX data centers. Most of our IBX data center leases have renewal options available to us. However, many of these renewal options provide for the rent to be set at then-prevailing market rates. To the extent that then-prevailing market rates or negotiated rates are higher than present rates, these higher costs may adversely impact our business and results of operations, or we may decide against renewing the lease. In the event that an IBX data center lease does not have a renewal option, or we fail to exercise a renewal option in a timely fashion and lose our right to renew the lease, we may not be successful in negotiating a renewal of the lease with the landlord. A failure to renew a lease could force us to exit a building prematurely, which could be disruptive todisrupt our business, harm our customer relationships, expose us to liability under our customer contracts, cause us to take impairment charges and negatively affect our operating results.results negatively.
We depend on a number of third parties to provide Internetinternet connectivity to our IBX data centers; if connectivity is interrupted or terminated, our operating results and cash flow could be materially and adversely affected.
The presence of diverse telecommunications carriers’carriers' fiber networks in our IBX data centers is critical to our ability to retain and attract new customers. We are not a telecommunications carrier, and as such, we rely on third parties to provide our customers with carrier services. We believe that the availability of carrier capacity will directly affect our ability to achieve our projected results. We rely primarily on revenue opportunities from the telecommunications carriers’carriers' customers to encourage them to invest the capital and operating resources required to connect from their centers to our IBX data centers. Carriers will likely evaluate the

revenue opportunity of an IBX data center based on the assumption that the environment will be highly competitive. We cannot provide assurance that each and every carrier will elect to offer its services within our IBX data centers or that once a carrier has decided to provide Internetinternet connectivity to our IBX data centers that it will continue to do so for any period of time.

30


Our new IBX data centers require construction and operation of a sophisticated redundant fiber network. The construction required to connect multiple carrier facilities to our IBX data centers is complex and involves factors outside of our control, including regulatory processes and the availability of construction resources. Any hardware or fiber failures on this network may result in significant loss of connectivity to our new IBX data center expansions. This could affect our ability to attract new customers to these IBX data centers or retain existing customers.
If the establishment of highly diverse Internetinternet connectivity to our IBX data centers does not occur, is materially delayed or is discontinued, or is subject to failure, our operating results and cash flow will be adversely affected.
We may be vulnerable to security breaches which could disrupt our operations and have a material adverse effect on our financial performance and operating results.
We face risks associated with unauthorized access to our computer systems, loss or destruction of data, computer viruses, malware, distributed denial-of-service attacks, or other malicious activities. These threats may result from human error, equipment failure, or fraud or malice on the part of employees or third parties. A party who is able to compromise the security measures on our networks or the security of our infrastructure could misappropriate either our proprietary information or the personal information of our customers or our employees, or cause interruptions or malfunctions in our operations or our customers’ operations. As we provide assurances to our customers that we provide a high level of security, such a compromise could be particularly harmful to our brand and reputation. We may be required to expend significant capital and resources to protect against such threats or to alleviate problems caused by breaches in security. As techniques used to breach security change frequently, and are generally not recognized until launched against a target, we may not be able to promptly detect that a cyber breach has occurred, or implement security measures in a timely manner or, if and when implemented, we may not be able to determine the extent to which these measures could be circumvented. Any breaches that may occur could expose us to increased risk of lawsuits, regulatory penalties, loss of existing or potential customers, damage relating to loss of proprietary information, harm to our reputation and increases in our security costs, which could have a material adverse effect on our financial performance and operating results. We maintain insurance coverage for cyber risks but such coverage may be unavailable or insufficient to cover our losses.    
We offer professional services to our customers where we consult on data center solutions and assist with implementations. We also offer managed services in certain of our foreign jurisdictions outside of the U.S. where we manage the data center infrastructure for our customers. The access gained from these services to our clients’ networks and data creates some risk that our clients' networks or data will be improperly accessed. We may also design our clients’ cloud storage systems in such a way that exposes our clients to increased risk of data breach.  If Equinix were held to be responsible for any such a breach, it could result in a significant loss to Equinix, including damage to Equinix’s client relationships, harm to our brand and reputation, and legal liability.
We have government customers, which subjects us to risks including early termination, audits, investigations, sanctions and penalties.
We derive some revenues from contracts with the U.S. government, state and local governments and foreign governments. Some of these customers may terminate all or part of their contracts at any time, without cause.
There is increased pressure for governments and their agencies, both domestically and internationally, to reduce spending. Some of our federal government contracts are subject to the approval of appropriations being made by the U.S. Congress to fund the expenditures under these contracts. Similarly, some of our contracts at the state and local levels are subject to government funding authorizations.
Additionally, government contracts often have unique terms and conditions, such as most favored customer obligations, and are generally subject to audits and investigations which could result in various civil and criminal penalties and administrative sanctions, including termination of contracts, refund of a portion of fees received, forfeiture of profits, suspension of payments, fines and suspensions or debarment from future government business.
Because we depend on the development and growth of a balanced customer base, including key magnet customers, failure to attract, grow and retain this base of customers could harm our business and operating results.
Our ability to maximize revenues depends on our ability to develop and grow a balanced customer base, consisting of a variety of companies, including enterprises, cloud, digital content and financial companies, and network service providers. We consider certain of these customers to be key magnets in that they draw in other customers. The more balanced the customer base within

31


each IBX data center, the better we will be able to generate significant interconnection revenues, which in turn increases our overall revenues. Our ability to attract customers to our IBX data centers will depend on a variety of factors, including the presence of multiple carriers, the mix of our offerings, the overall mix of customers, the presence of key customers attracting business through vertical market ecosystems, the IBX data center’scenter's operating reliability and security and our ability to effectively market our offerings. However, some of our customers may face competitive pressures and may ultimately not be successful or may be consolidated through merger or acquisition. If these customers do not continue to use our IBX data centers it may be disruptive to our business. Finally, the uncertain global economic climate may harm our ability to attract and retain customers if customers slow spending, or delay decision-making on our offerings, or if customers begin to have difficulty paying us and we experience increased churn in our customer base. Any of these factors may hinder the development, growth and retention of a balanced customer base and adversely affect our business, financial condition and results of operations.
We may be subject to securities class action and other litigation, which may harm our business and results of operations.
We may be subject to securities class action or other litigation. For example, securities class action litigation has often been brought against a company following periods of volatility in the market price of its securities. Litigation can be lengthy, expensive, and divert management’smanagement's attention and resources. Results cannot be predicted with certainty and an adverse outcome in litigation could result in monetary damages or injunctive relief thatrelief. Further, any payments made in settlement may directly reduce our revenue under U.S. GAAP and could negatively impact our operating results for the period.  For all of these reasons, litigation could seriously harm our business, results of operations, financial condition or cash flows.
We may not be able to protect our intellectual property rights.
We cannot make assurances that the steps taken by us to protect our intellectual property rights will be adequate to deter misappropriation of proprietary information or that we will be able to detect unauthorized use and take appropriate steps to enforce our intellectual property rights. We also are subject to the risk of litigation alleging infringement of third-party intellectual property rights. Any such claims could require us to spend significant sums in litigation, pay damages, develop non-infringing intellectual property or acquire licenses to the intellectual property that is the subject of the alleged infringement.

Government regulation may adversely affect our business.
Various laws and governmental regulations, both in the U.S. and abroad, governing Internet relatedinternet-related services, related communications services and information technologies remain largely unsettled, even in areas where there has been some legislative action. For example, the Federal Communications Commission ("FCC") recently adopted newoverturned network neutrality rules, thatwhich may result in material changes in the regulations and contribution regime affecting us and our customers. Likewise, as partFurthermore, the U.S. Congress and state legislatures are reviewing and considering changes to the new FCC rules making the future of a reviewnetwork neutrality and its impact on Equinix uncertain. There may also be forthcoming regulation in the U.S. in the areas of cybersecurity, data privacy and data security, any of which could impact Equinix and our customers. Similarly, data privacy regulations outside of the current equity market structure, the SecuritiesU.S. continue to evolve and Exchange Commission and the Commodity Futures Trading Commission (“CFTC”) have both sought comments regarding the regulation of independent data centers, suchmust be addressed by Equinix as us, which provide colocation for financial markets and exchanges. The CFTC is also considering regulation of companies that use automated and high-frequency trading systems. Any such regulation may ultimately affect our provision of offerings.a global company.
It also may take years to determineWe remain focused on whether and how existing and changing laws, such as those governing intellectual property, privacy, libel, telecommunications services, data flows/data localization, carbon emissions impact, and taxation apply to the Internetinternet and to related offerings such as ours,ours; and substantial resources may be required to comply with regulations or bring any non-compliant business practices into compliance with such regulations. In addition, the continuing development of the market for online commerce and the displacement of traditional telephony service by the Internetinternet and related communications services may prompt an increased call for more stringent consumer protection laws or other regulation both in the U.S. and abroad that may impose additional burdens on companies conducting business online and their service providers.
The adoption, or modification of laws or regulations relating to the Internetinternet and our business, or interpretations of existing laws, could have a material adverse effect on our business, financial condition and results of operations.

Industry consolidation may have a negative impact on our business model.
If customers combine businesses, they may require less colocation space, which could lead to churn in our customer base. Regional competitors may also consolidate to become a global competitor. Consolidation of our customers and/or our competitors may present a risk to our business model and have a negative impact on our revenues.
Terrorist activity throughout the world and military action to counter terrorism could adversely impact our business.
The continued threat of terrorist activity and other acts of war or hostility contribute to a climate of political and economic uncertainty. Due to existing or developing circumstances, we may need to incur additional costs in the future to provide enhanced security, including cyber security, which would have a material adverse effect on our business and results of operations. These circumstances may also adversely affect our ability to attract and retain customers, our ability to raise capital and the operation and maintenance of our IBX data centers.
We have various mechanisms in place that may discourage takeover attempts.
Certain provisions of our certificate of incorporation and bylaws may discourage, delay or prevent a third party from acquiring control of us in a merger, acquisition or similar transaction that a stockholder may consider favorable. Such provisions include:
ownership limitations and transfer restrictions relating to our stock that are intended to facilitate our compliance with certain REIT rules relating to share ownership;
authorization for the issuance of “blank check”"blank check" preferred stock;
the prohibition of cumulative voting in the election of directors;
limits on the persons who may call special meetings of stockholders;
limits on stockholder action by written consent; and
advance notice requirements for nominations to the Board of Directors or for proposing matters that can be acted on by stockholders at stockholder meetings.
In addition, Section 203 of the Delaware General Corporation Law, which restricts certain business combinations with interested stockholders in certain situations, may also discourage, delay or prevent someone from acquiring or merging with us.
Risks Related to Our Taxation as a REIT
We may not remain qualified for taxation as a REIT.
We have elected to be taxed as a REIT for U.S. federal income tax purposes beginning with our 2015 taxable year. We believe that our organization and method of operation comply with the rules and regulations promulgated under the Internal Revenue Code of 1986, as amended (the "Code"), such that we will continue to qualify for taxation as a REIT. However, we cannot assure you that we have qualified for taxation as a REIT or that we will remain so qualified. Qualification for taxation as a REIT involves the application of highly technical and complex provisions of the Code to our operations as well as various factual determinations concerning matters and circumstances not entirely within our control. There are limited judicial or administrative interpretations of applicable REIT provisions of the Code.
If, in any taxable year, we fail to remain qualified for taxation as a REIT and are not entitled to relief under the Code:
we will not be allowed a deduction for distributions to stockholders in computing our taxable income;

we will be subject to federal and state income tax on our taxable income at regular corporate income tax rates; and
we would not be eligible to elect REIT status again until the fifth taxable year that begins after the first year for which we failed to qualify for taxation as a REIT.
Any such corporate tax liability could be substantial and would reduce the amount of cash available for other purposes. If we fail to remain qualified for taxation as a REIT, we may need to borrow additional funds or liquidate some investments to pay any additional tax liability. Accordingly, funds available for investment and distributions to stockholders could be reduced.
As a REIT, failure to make required distributions would subject us to federal corporate income tax.
We paid quarterly distributions in 2018 and have declared a quarterly distribution to be paid on March 20, 2019. The amount, timing and form of any future distributions will be determined, and will be subject to adjustment, by our Board of Directors. To remain qualified for taxation as a REIT, we are generally required to distribute at least 90% of our REIT taxable income (determined without regard to the dividends paid deduction and excluding net capital gain) each year, or in limited circumstances, the following year, to our stockholders. Generally, we expect to distribute all or substantially all of our REIT taxable income. If our cash available for distribution falls short of our estimates, we may be unable to maintain distributions that approximate our REIT taxable income and may fail to remain qualified for taxation as a REIT. In addition, our cash flows from operations may be insufficient to fund required distributions as a result of differences in timing between the actual receipt of income and the payment of expenses and the recognition of income and expenses for federal income tax purposes, or the effect of nondeductible expenditures, such as capital expenditures, payments of compensation for which Section 162(m) of the Code denies a deduction, interest expense deductions limited by Section 163(j) of the Code, the creation of reserves or required debt service or amortization payments.
To the extent that we satisfy the 90% distribution requirement but distribute less than 100% of our REIT taxable income, we will be subject to federal corporate income tax on our undistributed taxable income. In addition, we will be subject to a 4% nondeductible excise tax on our undistributed taxable income if the actual amount that we distribute to our stockholders for a calendar year is less than the minimum amount specified under the Code.
We may be required to borrow funds, sell assets or raise equity to satisfy our REIT distribution requirements.
Due to the size and timing of future distributions, including any distributions made to satisfy REIT distribution requirements, 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. A significant 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. Significantly more 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 other risks described elsewhere in this Form 10-K.
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.
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 U.S. federal income tax purposes, we must satisfy tests concerning, among other things, the sources of our income, the nature and diversification of our assets and the amounts we distribute to our stockholders. For example, under the Code, no more than 20% of the value of the assets of a REIT may be represented by securities of one or more TRSs. Similar rules apply to other nonqualifying assets. These limitations may affect our ability to make large investments in other non-REIT qualifying operations or assets. In addition, in order to maintain our qualification for taxation as a REIT, we must distribute at least 90% of our REIT taxable income, determined without regard to the dividends paid deduction and excluding any net capital gains. Even if we maintain our qualification for taxation as a REIT, we will be subject to U.S. federal income tax

at regular corporate income tax rates for our undistributed REIT taxable income, as well as U.S. federal income tax at regular corporate income tax rates for income recognized by our TRSs; we also pay taxes in the foreign jurisdictions in which our international assets and operations are held and conducted regardless of our REIT status. Because of these distribution requirements, we will likely not be able to fund future capital needs and investments from operating cash flow. As such, compliance with REIT tests may hinder our ability to make certain attractive investments, including the purchase of significant nonqualifying assets and the material expansion of non-real estate activities.
Our ability to fully deduct our interest expense may be limited, or we may be required to adjust the tax depreciation of our real property in order to maintain the full deductibility of our interest expense.
The Code limits interest deductions for businesses, whether in corporate or passthrough form, to the sum of the taxpayer's business interest income for the tax year and 30% of the taxpayer's adjusted taxable income for that tax year. This limitation does not apply to an "electing real property trade or business". Although REITs are permitted to make such an election, we do not currently intend to do so. If we so elect in the future, depreciable real property that we hold (including specified improvements) would be required to be depreciated for U.S. federal income tax purposes under the alternative depreciation system of the Code, which generally imposes a class life for depreciable real property as long as forty years.
As a REIT, we are limited in our ability to fund distribution payments using cash generated through our TRSs.
Our ability to receive distributions from our TRSs is limited by the rules with which we must comply to maintain our qualification for taxation as a REIT. In particular, at least 75% of our gross income for each taxable year as a REIT must be derived from real estate. Consequently, no more than 25% of our gross income may consist of dividend income from our TRSs and other nonqualifying types of income. Thus, our ability to receive distributions from our TRSs may be limited and may impact our ability to fund distributions to our stockholders using cash flows from our TRSs. Specifically, if our TRSs become highly profitable, we might become limited in our ability to receive net income from our TRSs in an amount required to fund distributions to our stockholders commensurate with that profitability.
In addition, a significant amount of our income and cash flows from our TRSs is generated from our international operations. In many cases, there are local withholding taxes and currency controls that may impact our ability or willingness to repatriate funds to the United States to help satisfy REIT distribution requirements.
Our extensive use of TRSs, including for certain of our international operations, may cause us to fail to remain qualified for taxation as a REIT.
Our operations include an extensive use of TRSs. The net income of our TRSs is not required to be distributed to us, and income that is not distributed to us generally is not subject to the REIT income distribution requirement. However, there may be limitations on our ability to accumulate earnings in our TRSs and the accumulation or reinvestment of significant earnings in our TRSs could result in adverse tax treatment. In particular, if the accumulation of cash in our TRSs causes (1) the fair market value of our securities in our TRSs to exceed 20% of the fair market value of our assets or (2) the fair market value of our securities in our TRSs and other nonqualifying assets to exceed 25% of the fair market value of our assets, then we will fail to remain qualified for taxation as a REIT. Further, a substantial portion of our TRSs are overseas, and a material change in foreign currency rates could also negatively impact our ability to remain qualified for taxation as a REIT.
The Code imposes limitations on the ability of our TRSs to utilize specified income tax deductions, including limits on the use of net operating losses and limits on the deductibility of interest expense.
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 and any stock repurchase program. Consequently, our distribution levels may fluctuate.
Even if we remain qualified for taxation as a REIT, some of our business activities are subject to corporate level income tax and foreign taxes, which will continue to reduce our cash flows, and we will have potential deferred and contingent tax liabilities.
Even if we remain qualified for taxation as a REIT, we may be subject to some federal, state, local and foreign taxes on our income and assets, taxes on any undistributed income, and state, local or foreign income, franchise, property and transfer taxes.

In addition, we could in certain circumstances be required to pay an excise or penalty tax, which could be significant in amount, in order to utilize one or more relief provisions under the Code to maintain our qualification for taxation as a REIT.
A portion of our business is conducted through wholly-owned TRSs because certain of our business activities could generate nonqualifying REIT income as currently structured and operated. The income of our U.S. TRSs will continue to be subject to federal and state corporate income taxes. In addition, our international assets and operations will continue to be subject to taxation in the foreign jurisdictions where those assets are held or those operations are conducted. Any of these taxes would decrease our earnings and our available cash.
We will also be subject to a federal corporate level income tax at the highest regular corporate income tax rate (currently 21%) 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, 2015, or (ii) an asset that we or our qualified REIT subsidiaries ("QRSs") hold following the liquidation or other conversion of a former TRS). This 21% tax is generally applicable to any disposition of such an asset during the five-year period after the date we first owned the asset as a REIT asset (e.g., January 1, 2015 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.
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 or fluctuations with respect to borrowings made or to be made by us to acquire or carry real estate assets and income from certain currency hedging transactions related to our non-U.S. 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, which we presently do. This increases the cost of our hedging activities because our TRSs are subject to tax on income or gains resulting from hedges entered into by them and may expose us to greater risks associated with changes in interest rates or exchange rates than we would otherwise want to bear. In addition, hedging losses in any of our TRSs may not provide any tax benefit, except for being carried forward for possible use against future income or gain in the TRSs.
Distributions payable by REITs generally do not qualify for preferential tax rates.
Dividends payable by U.S. corporations to noncorporate stockholders, such as individuals, trusts and estates, are generally eligible for reduced U.S. federal income tax rates applicable to "qualified dividends." Distributions paid by REITs generally are not treated as "qualified dividends" under the Code, and the reduced rates applicable to such dividends do not generally apply. However, for tax years beginning after 2017 and before 2026, REIT dividends paid to noncorporate stockholders are generally taxed at an effective tax rate lower than applicable ordinary income tax rates due to the availability of a deduction under the Code for specified forms of income from passthrough entities. More favorable rates will nevertheless continue to apply to regular corporate "qualified" dividends, which may cause some investors to perceive that an investment in a REIT is less attractive than an investment in a non-REIT entity that pays dividends, thereby reducing the demand and market price of our common stock.
Our certificate of incorporation contains restrictions on the ownership and transfer of our stock, though they may not be successful in preserving our qualification for taxation as a REIT.
In order for us to remain qualified for taxation as a REIT, no more than 50% of the value of outstanding shares of our stock may be owned, beneficially or constructively, by five or fewer individuals at any time during the last half of each taxable year other than the first year for which we elected to be taxed as a REIT. In addition, rents from "affiliated tenants" will not qualify as qualifying REIT income if we own 10% or more by vote or value of the customer, whether directly or after application of attribution rules under the Code. Subject to certain exceptions, our certificate of incorporation prohibits any stockholder from owning, beneficially or constructively, more than (i) 9.8% in value of the outstanding shares of all classes or series of our capital stock or (ii) 9.8% in value or number, whichever is more restrictive, of the outstanding shares of any class or series of our capital stock. We refer to these restrictions collectively as the "ownership limits" and we included them in our certificate of incorporation to facilitate our compliance with REIT tax rules. The constructive ownership rules under the Code are complex and may cause the outstanding stock owned by a group of related individuals or entities to be deemed to be constructively owned by one individual or entity. As a result, the acquisition of less than 9.8% of our outstanding common stock (or the outstanding shares of any class or series of our stock) by an individual or entity could cause that individual or entity or another individual or entity to own constructively in excess of the relevant ownership limits. Any attempt to own or transfer shares of our common stock or of any of our other capital stock in violation of these restrictions may result in the shares being automatically transferred to a charitable trust or may be void. Even though our certificate of incorporation contains the ownership limits, there can be no assurance that these

provisions will be effective to prevent our qualification for taxation as a REIT from being jeopardized, including under the affiliated tenant rule. Furthermore, there can be no assurance that we will be able to monitor and enforce the ownership limits. If the restrictions in our certificate of incorporation are not effective and, as a result, we fail to satisfy the REIT tax rules described above, then absent an applicable relief provision, we will fail to remain qualified for taxation as a REIT.
In addition, the ownership and transfer restrictions could delay, defer or prevent a transaction or a change in control that might involve a premium price for our stock or otherwise be in the best interest of our stockholders. As a result, the overall effect of the ownership and transfer restrictions may be to render more difficult or discourage any attempt to acquire us, even if such acquisition may be favorable to the interests of our stockholders.
Legislative or other actions affecting REITs could have a negative effect on us or our stockholders.
At any time, the federal or state income tax laws governing REITs, or the administrative interpretations of those laws, may be amended. Federal and state tax laws are constantly under review by persons involved in the legislative process, the Internal Revenue Service, the U.S. 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 TRSs, particularly non-U.S. TRSs.
In addition, December 2017 legislation made substantial changes to the Code, particularly as it relates to the taxation of both corporate income and international income. Among those changes are a significant permanent reduction in the generally applicable corporate income tax rate and modifications to the calculation of taxable income, including changes to credits and deductions available to businesses and individuals. This legislation also imposes additional limitations on the deduction of net operating losses, which may in the future cause us to make additional distributions that will be taxable to our stockholders to the extent of our current or accumulated earnings and profits in order to comply with the REIT distribution requirements. The effect of these and other changes made in this legislation is still uncertain in many respects, both in terms of their direct effect on the taxation of an investment in our common stock and their indirect effect on the value of assets owned by us. Furthermore, many of the provisions of the new law will require additional guidance in order to assess their effect. It is also possible that there will be subsequent legislative amendments proposed with respect to the new law, the effect of which cannot be predicted and may be adverse to us or our stockholders. Our stockholders are encouraged to consult with their tax advisors about the potential effects that changes in law may have on them and their ownership of our common stock.
We could incur adverse tax consequences if we fail to integrate an acquisition target in compliance with the requirements to qualify for taxation as a REIT.
We periodically explore and occasionally consummate merger and acquisition transactions. When we consummate these transactions, we structure the acquisition to successfully manage the REIT income, asset, and distribution tests that we must satisfy. We believe that we have and will in the future successfully integrate our acquisition targets in a manner that has and will allow us to timely satisfy the REIT tests applicable to us, but if we failed or in the future fail to do so, then we could jeopardize or lose our qualification for taxation as a REIT, particularly if we were not eligible to utilize relief provisions set forth in the Code.

As of January 31, 2016,2019, we had 69,025,41280,761,276 shares of our common stock outstanding held by approximately 274278 registered holders.
In October 2014, our Board of Directors declared a special distribution of $416.0 million, or approximately $7.57 per share (the “2014 Special Distribution”), to our common stockholders in connection with our plan to convert to a REIT. The 2014 Special Distribution was paid on November 25, 2014 to our common stockholders of record as of the close of business on October 27, 2014. Common stockholders had the option to elect to receive payment of the 2014 Special Distribution in the form of stock or cash, with the total cash payment to all stockholders limited to no more than 20% of the total distribution. The number of shares distributed was determined based upon common stockholder elections and the average closing price of our common stock on the three trading days commencing on November 18, 2014 or $224.45 per share. As such, we issued 1.5 million shares of our common stock and paid $83.3 million in connection with the 2014 Special Distribution.
In connection with our conversion to a REIT effective January 1, 2015, we began paying quarterly dividends in 2015. On each of February 19, 2015, May 7, 2015, July 29, 2015 and October 28, 2015, our Board of Directors declared a quarterly cash dividend of $1.69 per share.

In September 2015, our Board of Directors declared a special distribution of $627.0 million, or approximately $10.95 per share (the “2015 Special Distribution”), to our common stockholders. The 2015 Special Distribution represented an amount that included the sum of: (1) foreign earnings and profits repatriated as dividend income in 2015; (2) taxable income in 2015 from depreciation recapture in respect of accounting method changes commenced in our pre-REIT period; and (3) certain other items of taxable income.
The 2015 Special Distribution was paid on November 10, 2015 to our common stockholders of record as of the close of business on October 8, 2015. Common stockholders had the option to elect to receive payment of the 2015 Special Distribution in the form of stock or cash, with the total cash payment to all stockholders limited to no more than 20% of the total distribution. The number of shares distributed was determined based upon common stockholder elections and the average closing price of our common stock on the three trading days commencing on November 3, 2015 or $297.03 per share. As such, we issued 1.7 million shares of our common stock and paid $125.5 million in connection with the 2015 Special Distribution.

Stock Performance Graph
The graph set forth below compares the cumulative total stockholder return on Equinix’sEquinix's common stock between December 31, 20102013 and December 31, 20152018 with the cumulative total return of (i) the S&P 500 Index, (ii) the NASDAQ Composite Index (iii) the NASDAQ Telecommunications Index and (iv)(iii) the FTSE NAREIT All REITs Index. The graph assumes the investment of $100.00 on December 31, 20102013 in Equinix’sEquinix's common stock and in each index, and assumes the reinvestment of dividends, if any. Equinix converted to a REIT effective January 1, 2015 and thus intends to compare the total stockholder return on Equinix’s common stock to the cumulative total return of the FTSE NAREIT All REITs Index instead of that of the NASDAQ Telecommunications index in future filings.

On January 1, 2018, we adopted Topic 606 using the modified retrospective method applied to those contracts which were not completed as of January 1, 2018. The increase in income tax expenseimpacts are primarily related to the costs to obtain a customer contract and from the recognition of installation revenue, which are recognized over the contract period, rather than over the estimated installation life as under the prior revenue standard. The consolidated statement of operations for the year ended December 31, 20132018 reflected the adoption of Topic 606. See Note 1 of the Notes to Consolidated Financial Statements in Item 8 of this Annual Report on Form 10-K.
(2)
The higher income tax expense for the year ended December 31, 2014 was primarily attributed to the de-recognition of $324.1 million of net deferred tax assets and deferred tax liabilities in December 2014, when our Board of Directors formally approved our conversion to a REIT and we reassessed the deferred tax assets and deferred tax liabilities of our U.S. operations included in the REIT structure.
(3)
During the year ended December 31, 2015, we paid $10.95 per share of special distribution and $6.76 per share of quarterly cash dividend. During the year ended December 31, 2014, we paid $7.57 per share of special distribution.

In November 2015, as more fully described in Note 11 of Notes to Consolidated Financial Statements in Item 8 of this Annual Report on Form 10-K, we issued and sold 2,994,792 shares of our common stock in a public offering. We received net proceeds of approximately $829.5 million, after deducting underwriting discounts, commissions and offering expenses.
We intend to use the net proceeds we received from the sale of our 2026 Senior Notes and from the sale of our common stock, as well as the net proceeds we received in January 2016 from our Term Loan B Commitments, for both merger and acquisition activities and general corporate purposes.
In November 2015, as more fully described in Note 2 of Notes to Consolidated Financial Statements in Item 8 of this Annual Report on Form 10-K, we completed our acquisition of Tokyo-based Bit-isle Inc. (“Bit-isle”) valued at ¥33.2 billion or approximately $275.4 million U.S. dollars.
In connection with our acquisition of Bit-isle, as more fully described in Note 9 of Notes to Consolidated Financial Statements, in September 2015 we entered into a term loan agreement (the “Bridge Term Loan Agreement”) with the Bank of Tokyo-Mitsubishi UFJ, Ltd. (“BTMU”). BTMU has committed to provide a senior bridge loan facility (the “Bridge Term Loan”) in the amount of up to ¥47.5 billion, or approximately $395.2 million at the exchange rate in effect on December 31, 2015. Proceeds from the Bridge Term Loan are to be used exclusively for the acquisition of Bit-isle, the repayment of Bit-isle’s existing debt and transaction costs incurred in connection with the closing of the Bridge Term Loan and the acquisition of Bit-isle. We borrowed ¥46.5 billion, or approximately $386.5 million in U.S. dollars at the exchange rate in effect on December 31, 2015, under the Bridge Term Loan in the fourth quarter of 2015. We intend to obtain permanent financing to replace and terminate the Bridge Term Loan in 2016.

In May 2015, as more fully described in Note 2 and Note 9 of Notes to Consolidated Financial Statements in Item 8 of this Annual Report on Form 10-K, we announced an offer for the entire issued and to be issued share capital of TelecityGroup, valued at approximately £2.4 billion, or $3.8 billion in U.S. dollars. The transaction closed in January 2016. The total consideration consisted of $1.7 billion in cash and 6.9 million shares of our common stock, valued at $2.1 billion. In connection with the transaction, we also entered into a bridge credit agreement (the "Bridge Loan") with J.P. Morgan Chase Bank, N.A. (“JPMCB”) as the initial lender and as administrative agent for the lenders (the “Lenders”), for a principal amount of £875.0 million; or approximately $1.3 billion. The Bridge Loan was dedicated solely for the acquisition of TelecityGroup and to satisfy funds certain requirements under UK takeover code. We terminated the Bridge Loan in January 2016.
In May 2015, we received a favorable response to the PLR request we had submitted to the IRS in connection with our conversion to a REIT for federal income tax purposes effective for the taxable year commencing January 1, 2015.
In April 2015, as more fully described in Note 9 of Notes to Consolidated Financial Statements in Item 8 of this Annual Report on Form 10-K, we entered into the first amendment (the “First Amendment”) of our credit agreement dated December 17, 2014 (the “Senior Credit Facility”). The amendment allowed for the conversion of the outstanding U.S. dollar-denominated principal amount of the term loan facility to an approximately equivalent amount denominated in four foreign currencies.  In connection with the execution of the amendment, on April 30, 2015, we repaid the U.S. dollar-denominated $490.0 million remaining principal balance of the term loan facility and immediately re-borrowed under the term loan facility the aggregate principal amount of CHF 47.8 million, €184.9 million, £92.6 million and ¥11.9 million, or approximately $490.0 million in U.S dollars in total.
Overview
Equinix provides global data center offerings that protect and connect the world’s most valued information assets. Global enterprises, financial services companies and content and network service providers rely upon Equinix’s leading insight and data centers in 33 markets around the world for the safekeeping of their critical IT equipment and the ability to directly connect to the networks that enable today’s information-driven economy. Equinix offers the following solutions: (i) premium data center colocation, (ii) interconnection and (iii) exchange and outsourced IT infrastructure services. As of December 31, 2015, we operated or had partner International Business Exchange (“IBX”) data centers in the Atlanta, Boston, Chicago, Dallas, Denver, Los Angeles, Miami, New York, Philadelphia, Rio de Janeiro, Sao Paulo, Seattle, Silicon Valley, Toronto and Washington, D.C. metro areas in the Americas region; France, Germany, Italy, the Netherlands, Switzerland, the United Arab Emirates and the United Kingdom in the Europe, Middle East and Africa (“EMEA”) region; and Australia, China, Hong Kong, Indonesia, Japan and Singapore in the Asia-Pacific region.

 Our data centers in 33 markets around the world are a global platform, which allows our customers to increase information and application delivery performance while significantly reducing costs. This global platform and the quality of our IBX data centers have enabled us to establish a critical mass of customers. As more customers choose our IBX data centers, it benefits their suppliers and business partners to colocate with us as well, in order to gain the full economic and performance benefits of our offerings. These partners, in turn, pull in their business partners, creating a “marketplace” for their services. Our global platform enables scalable, reliable and cost-effective colocation, interconnection and traffic exchange that lowers overall cost and increases flexibility. Our focused business model is built on our critical mass of customers and the resulting “marketplace” effect. This global platform, combined with our strong financial position, continues to drive new customer growth and bookings.
Historically, our market has been served by large telecommunications carriers who have bundled telecommunications products and services with their colocation offerings. The data center market landscape has evolved to include cloud computing/utility providers, application hosting providers and systems integrators, managed infrastructure hosting providers and colocation providers. More than 350 companies provide data center solutions in the U.S. alone. Each of these data center solutions providers can bundle various colocation, interconnection and network offerings, and outsourced IT infrastructure services. We are able to offer our customers a global platform that reaches 21 countries with proven operational reliability, improved application performance and network choice, and a highly scalable set of offerings.

Our utilization rate represents the percentage of our cabinet space billing versus net sellable cabinet space available, taking into account power limitations. Our utilization rate was approximately 81% and 78% as of December 31, 2015 and December 31, 2014, respectively. However, excluding the impact of IBX data center expansion projects that have opened during the last 12 months, our utilization rate would be approximately 85% as of December 31, 2015. Our utilization rate varies from market to market among our IBX data centers across the Americas, EMEA and Asia-Pacific regions. We continue to monitor the available capacity in each of our selected markets. To the extent we have limited capacity available in a given market, it may limit our ability for growth in that market. We perform demand studies on an ongoing basis to determine if future expansion is warranted in a market. In addition, power and cooling requirements for most customers are growing on a per unit basis. As a result, customers

41


are consuming an increasing amount of power per cabinet. Although we generally do not control the amount of power our customers draw from installed circuits, we have negotiated power consumption limitations with certain high power-demand customers. This increased power consumption has driven us to build out our new IBX data centers to support power and cooling needs twice that of previous IBX data centers. We could face power limitations in our IBX data centers, even though we may have additional physical cabinet capacity available within a specific IBX data center. This could have a negative impact on the available utilization capacity of a given IBX data center, which could have a negative impact on our ability to grow revenues, affecting our financial performance, operating results and cash flows.

Strategically, we will continue to look at attractive opportunities to grow our market share and selectively improve our footprint and offerings. As was the case with our recent expansions and acquisitions, our expansion criteria will be dependent on a number of factors, such as demand from new and existing customers, quality of the design, power capacity, access to networks, capacity availability in the current market location, amount of incremental investment required by us in the targeted property, lead-time to break even on a free cash flow basis, and in-place customers. Like our recent expansions and acquisitions, the right combination of these factors may be attractive to us. Depending on the circumstances, these transactions may require additional capital expenditures funded by upfront cash payments or through long-term financing arrangements in order to bring these properties up to Equinix standards. Property expansion may be in the form of purchases of real property, long-term leasing arrangements or acquisitions. Future purchases, construction or acquisitions may be completed by us or with partners or potential customers to minimize the outlay of cash, which can be significant.

Our business is based on a recurring revenue model comprised of colocation and related interconnection and managed infrastructure offerings. We consider these offerings recurring because our customers are generally billed on a fixed and recurring basis each month for the duration of their contract, which is generally one to three years in length. Our recurring revenues have comprised more than 90% of our total revenues during the past three years. In addition, during any given quarter of the past three years, more than half of our monthly recurring revenue bookings came from existing customers, contributing to our revenue growth. Our largest customer accounted for approximately 3% of our recurring revenues for the period ended December 31, 2015 and 2% of our recurring revenues for the periods ended December 31, 2014 and 2013. Our 50 largest customers accounted for approximately 34%, 36% and 35% of our recurring revenues for the years ended December 31, 2015, 2014 and 2013.

Our non-recurring revenues are primarily comprised of installation services related to a customer’s initial deployment and professional services that we perform. These services are considered to be non-recurring because they are billed typically once, upon completion of the installation or the professional services work performed. The majority of these non-recurring revenues are typically billed on the first invoice distributed to the customer in connection with their initial installation. However, revenues from installation services are deferred and recognized ratably over the expected life of the customer installation. Additionally, revenue from contract settlements, when a customer wishes to terminate their contract early, is recognized when no remaining performance obligations exist and collectability is reasonably assured, to the extent that the revenue has not previously been recognized. As a percentage of total revenues, we expect non-recurring revenues to represent less than 10% of total revenues for the foreseeable future.

Our Americas revenues are derived primarily from colocation and related interconnection offerings, and our EMEA and Asia-Pacific revenues are derived primarily from colocation and managed infrastructure offerings.

The largest components of our cost of revenues are depreciation, rental payments related to our leased IBX data centers, utility costs, including electricity and bandwidth, IBX data center employees’ salaries and benefits, including stock-based compensation, repairs and maintenance, supplies and equipment and security services. A substantial majority of our cost of revenues is fixed in nature and should not vary significantly from period to period, unless we expand our existing IBX data centers or open or acquire new IBX data centers. However, there are certain costs that are considered more variable in nature, including utilities and supplies that are directly related to growth in our existing and new customer base. We expect the cost of our utilities, specifically electricity, will generally increase in the future on a per-unit or fixed basis, in addition to the variable increase related to the growth in consumption by our customers. In addition, the cost of electricity is generally higher in the summer months, as compared to other times of the year. To the extent we incur increased utility costs, such increased costs could materially impact our financial condition, results of operations and cash flows. Furthermore, to the extent we incur increased electricity costs as a result of either climate change policies or the physical effects of climate change, such increased costs could materially impact our financial condition, results of operations and cash flows.
Sales and marketing expenses consist primarily of compensation and related costs for sales and marketing personnel, including stock-based compensation, sales commissions, marketing programs, public relations, promotional materials and travel, as well as bad debt expense and amortization of customer contract intangible assets.


42


General and administrative expenses consist primarily of salaries and related expenses, including stock-based compensation, accounting, legal and other professional service fees, and other general corporate expenses, such as our corporate regional headquarters office leases and some depreciation expense.

Due to our recurring revenue model, and a cost structure which has a large base that is fixed in nature and generally does not grow in proportion to revenue growth, we expect our cost of revenues, sales and marketing expenses and general and administrative expenses to decline as a percentage of revenues over time, although we expect each of them to grow in absolute dollars in connection with our growth. However, for cost of revenues, this trend may periodically be impacted when a large expansion project opens or is acquired, and before it starts generating any meaningful revenue. Furthermore, in relation to cost of revenues, we note that the Americas region has a lower cost of revenues as a percentage of revenue than either EMEA or Asia-Pacific. This is due to both the increased scale and maturity of the Americas region, compared to either the EMEA or Asia-Pacific region, as well as a higher cost structure outside of the Americas, particularly in EMEA. While we expect all three regions to continue to see lower cost of revenues as a percentage of revenues in future periods, we expect the trend that sees the Americas having the lowest cost of revenues as a percentage of revenues to continue. As a result, to the extent that revenue growth outside the Americas grows in greater proportion than revenue growth in the Americas, our overall cost of revenues as a percentage of revenues may increase in future periods. Sales and marketing expenses may periodically increase as a percentage of revenues as we continue to scale our operations to invest in sales and marketing initiatives to further increase our revenue, including the hiring of additional headcount and new product innovations. General and administrative expenses may also periodically increase as a percentage of revenues as we continue to scale our operations to support our growth.
Real Estate Investment Trust Conversion
We began operating as a REIT for federal income tax purposes effective January 1, 2015. In May 2015, we received a favorable PLR from the IRS in connection with our conversion to a REIT. As of December 31, 2015, our REIT structure includes all of our data center operations in the U.S., Canada, Europe and the historical data center operations in Japan. Our data center operations in other jurisdictions, as well as the data center operations acquired in the Bit-isle Acquisition, have initially been designated as TRSs.
As a REIT, we generally are permitted to deduct from federal taxable income the dividends we pay to our stockholders (including, for this purpose, the value of any deemed distribution on account of adjustments to the conversion rate relating to our outstanding debt securities that are convertible into our common stock). 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. Nevertheless, the income of our TRSs which hold our U.S. operations that may not be REIT-compliant, are subject, as applicable, to federal and state corporate income tax. Likewise, our foreign subsidiaries continue to be subject to foreign income taxes in jurisdictions in which they hold assets or conduct operations, regardless of whether held or conducted through TRSs or through QRSs. We are also subject to a separate corporate income tax 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 present or former C corporation (such as (i) an asset that we held as of the effective date of our REIT election, that is, January 1, 2015 or (ii) an asset that we hold in a QRS following the liquidation or other conversion of a former TRS). This built-in-gains 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, 2015 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. If we fail to qualify for taxation as a REIT, we will be subject to federal income tax at regular corporate 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 TRSs' 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 may not follow them at all.
We incurred a total of approximately $364.0 million in tax liabilities associated with a change in our methods of depreciating and amortizing various data center assets for tax purposes from our prior methods to methods that are more consistent with the characterization of such assets as real property for REIT purposes. These liabilities were generally payable over a four-year period starting in 2012.

On September 28, 2015, we announced the declaration by our Board of Directors of a special distribution (the “2015 Special Distribution”) of $627.0 million on our shares of common stock, payable in either common stock or cash to, and at the election of, our stockholders of record as of October 8, 2015 (the “Record Date”). The 2015 Special Distribution included: (1) foreign earnings and profits repatriated as dividend income recognized in 2015; (2) taxable income in 2015 from depreciation recapture in respect of accounting method changes commenced in our pre-REIT period; and (3) certain other items of taxable income. The 2015 Special Distribution was paid on November 10, 2015 to our common stockholders of record as of the close of business on October 8, 2015 in the form of an aggregate of approximately $125.5 million in cash and 1.69 million shares of our common stock.

43


The 2015 Special Distribution followed an initial special distribution of $416.0 million paid in cash and common stock to stockholders in November 2014.
In connection with our conversion to a REIT effective January 1, 2015, we also paid quarterly cash dividends of $1.69 per share on each of March 25, 2015, June 17, 2015, September 16, 2015, and December 16, 2015. The amount of the 2015 Special Distribution, plus the amount of all of our other distributions during 2015 and the value of the deemed distributions on account of the adjustments to the conversion rate relating to our outstanding 4.75% convertible subordinated notes that were made as a result of all our 2015 distributions, equaled or exceeded the taxable income that we recognized in 2015.
We have initially designated all the legal entities acquired in the Bit-isle acquisition as taxable REIT subsidiaries (“TRSs”), which we believe will not impact our qualification for taxation as a REIT. We plan to integrate the data center business of Bit-isle into our REIT structure by the end of 2016.
We will initially designate all the legal entities acquired in the TelecityGroup acquisition as taxable REIT subsidiaries (“TRSs”), which we believe will not impact our qualification for taxation as a REIT. We plan to integrate a significant portion of the TelecityGroup businesses into our REIT structure by the end of 2016 and to complete almost all remaining REIT integration efforts in the first half of 2017.
We continue to monitor our REIT compliance to maintain our qualification for taxation as a REIT. For this, and other reasons, as necessary, we may convert certain of our data center operations in additional countries into the REIT in future periods.
Results of Operations
Our results of operations for the year ended December 31, 2015 include the results of operations of the Nimbo and Bit-isle acquisitions from January 15, 2015 and November 2, 2015 respectively. Our results of operations for the year ended December 31, 2013 include the operations of Frankfurt Kleyer 90 carrier hotel acquisition from October 1, 2013.

Americas Revenues. During the years ended December 31, 2015 and 2014, our revenues from the United States, the largest revenue contributor in the Americas region for the periods, represented approximately 93% and 91%, respectively, of the regional revenues. Growth in Americas revenues was primarily due to (i) $44.5 million of revenue generated from our recently-opened IBX data centers and IBX data center expansions in the Dallas, New York, Rio de Janeiro, Silicon Valley, Toronto and Washington DC metro areas and (ii) an increase in orders from both our existing customers and new customers during the period as reflected in the growth in our utilization rate, as discussed above, in both our new and existing IBX data centers.. During the year ended December 31, 2015, currency fluctuations resulted in approximately $37.7 million of unfavorable foreign currency impact on our Americas revenues primarily due to the generally stronger U.S. dollar relative to the Brazilian real and Canadian dollar during the year ended December 31, 2015 compared to the year ended December 31, 2014. We expect that our Americas revenues will continue to grow in future periods as a result of continued growth in the recently-opened IBX data centers and additional IBX data center expansions currently taking place in the Atlanta, Sao Paulo and Washington, D.C. metro areas, which are expected to open during 2016 and 2017. Our estimates of future revenue growth also take into account expected changes in recurring revenues attributed to customer bookings, customer churn or changes or amendments to customers’ contracts.
EMEA Revenues.  During the years ended December 31, 2015 and 2014, our revenues from the United Kingdom, the largest revenue contributor in the EMEA region for the periods, represented approximately 37% and 36%, respectively, of the regional revenues. Our EMEA revenue growth was due to (i) $23.6 million of revenue generated from our recently-opened IBX data centers and IBX data center expansions in the Amsterdam, Frankfurt, London, and Paris metro areas and (ii) an increase in orders from both our existing customers and new customers during the period as reflected in the growth in our utilization rate, as discussed above, in both our new and existing IBX data centers. During the year ended December 31, 2015, currency fluctuations resulted in approximately $94.1 million of net unfavorable foreign currency impact on our EMEA revenues primarily due to the generally stronger U.S. dollar relative to the British pound and Euro during the year ended December 31, 2015 compared to the year ended December 31, 2014. We expect that our EMEA revenues will continue to grow in future periods as a result of continued growth in recently-opened IBX data centers and additional IBX data center expansions currently taking place in the Amsterdam, Frankfurt and London metro areas, which are expected to open during 2016 and 2017, and as a result of our acquisition of TelecityGroup, which closed in January 2016. Our estimates of future revenue growth also take into account expected changes in recurring revenues attributed to customer bookings, customer churn or changes or amendments to customers' contracts.
Asia-Pacific Revenues.  Our revenues from Singapore, the largest revenue contributor in the Asia-Pacific region, represented approximately 37% and 38% of the regional revenues for the years ended December 31, 2015 and 2014. Our Asia-Pacific revenue growth was due to (i) $58.8 million of revenue generated from our recently-opened IBX data centers and IBX data center expansions in the Hong Kong, Melbourne, Shanghai, Singapore and Tokyo metro areas and (ii) an increase in orders from both our existing customers and new customers during the period as reflected in the growth in our utilization rate, as discussed above, in both our new and existing IBX data centers. In addition, our Asia-Pacific revenues for the year ended December 31, 2015 included $21.6 million of revenue attributable to our acquisition of Bit-isle, which closed on November 2, 2015. During the year ended December 31, 2015, currency fluctuations resulted in approximately $46.4 million of net unfavorable foreign currency impact on our Asia-Pacific revenues primarily due to the generally stronger U.S. dollar relative to the Australian dollar, Japanese yen and Singapore dollar during the year ended December 31, 2015 compared to the year ended December 31, 2014. We expect that our Asia-Pacific revenues will continue to grow in future periods as a result of continued growth in these recently-opened IBX data center expansions and additional expansions currently taking place in the Hong Kong, Sydney, and Tokyo metro areas, which are expected to open during 2016 and 2017, and as a result of our acquisition of Bit-isle. Our estimates of future revenue growth also take into account expected changes in recurring revenues attributed to customer bookings, customer churn or changes or amendments to customers’ contracts.

Americas Cost of Revenues. Our Americas cost of revenues for the years ended December 31, 2015 and 2014 included $219.1 million and $218.4 million, respectively, of depreciation expense. The increase in our Americas cost of revenues was primarily due to (i) $17.4 million of higher office expense, utilities, and repair and maintenance costs in support of our business growth, (ii) $7.3 million of higher compensation costs, including general salaries, bonuses, stock-based compensation and headcount growth (1,032 employees included in Americas cost of revenues as of December 31, 2015 versus 941 as of December 31, 2014), (iii) $3.9 million of higher costs associated with equipment resales to support the growth of non-recurring revenues and (iv) $3.5 million of higher property and real property tax expenses primarily due to our newly-opened IBX data centers during the year ended December 31, 2015, partially offset by $2.6 million of lower rent and facility costs primarily as a result of certain leases being accounted for as capital leases rather than as operating leases. During the year ended December 31, 2015, currency fluctuations resulted in approximately $29.6 million of net favorable foreign currency impact on our Americas cost of revenues primarily due to the generally stronger U.S. dollar relative to the Brazilian real and Canadian dollar during the year ended December 31, 2015 compared to the year ended December 31, 2014. We expect Americas cost of revenues to increase as we continue to grow our business.
EMEA Cost of Revenues. EMEA cost of revenues included $97.8 million of depreciation expense for the years ended December 31, 2015 and 2014. The increase in our EMEA cost of revenues was primarily due to $3.4 million of higher compensation costs, including general salaries, bonuses, stock-based compensation and headcount growth (541 employees included in EMEA cost of revenues as of December 31, 2015 versus 473 as of December 31, 2014), and $13.2 million of higher costs associated with equipment resales, bandwidth and other customer services in support of our non-recurring revenues growth as well as an increase in net losses related to cash flow derivatives. These increases were partially offset by $5.0 million of lower rent, facilities and utilities expenses and $2.7 million of lower consulting costs. During the year ended December 31, 2015, the impact of foreign currency fluctuations resulted in approximately $50.8 million of net favorable foreign currency impact on our EMEA cost of revenues primarily due to the generally stronger U.S. dollar relative to the British pound and Euro during the year ended December 31, 2015 compared to the year ended December 31, 2014. We expect EMEA cost of revenues to increase as we continue to grow our business and as a result of our acquisition of TelecityGroup, which closed in January 2016.
Asia-Pacific Cost of Revenues. Asia-Pacific cost of revenues for the year ended December 31, 2015 included $17.4 million of cost of revenues attributable to our acquisition of Bit-isle, which closed in November 2015. Excluding cost of revenues attributable to Bit-isle, Asia-Pacific cost of revenues for the year ended December 31, 2015 was $286.2 million compared to $255.6 for the year ended December 31, 2014. Depreciation expense, excluding Bit-isle, was $116.9 million and $101.4 million for the years ended December 31, 2015 and 2014, respectively. Growth in depreciation expense was primarily due to our IBX data center expansion activity. In addition to the increase in depreciation expense, the increase in Asia-Pacific cost of revenues, excluding cost of revenues attributable to Bit-isle, was primarily due to $9.9 million in higher consulting costs, utility costs, repairs and maintenance costs and rent and facility costs in support of our revenue growth as well as $2.8 million of higher compensation

costs, including general salaries, bonuses, stock-based compensation and headcount growth (390 employees included in Asia-Pacific cost of revenues, excluding Bit-isle employees, as of December 31, 2015 versus 342 as of December 31, 2014). During the year ended December 31, 2015, currency fluctuations resulted in approximately $24.7 million of net favorable foreign currency impact on our Asia-Pacific cost of revenues primarily due to the generally stronger U.S. dollar relative to the Australian dollar, Japanese yen and Singapore dollar during the year ended December 31, 2015 compared to the year ended December 31, 2014. We expect Asia-Pacific cost of revenues to increase as we continue to grow our business and as a result of our acquisition of Bit-isle.

Americas Sales and Marketing Expenses. The increase in our Americas sales and marketing expenses was primarily due to (i) $26.5 million of higher compensation costs, including sales compensation, general salaries, bonuses, commission and stock-based compensation as a result of business and headcount growth (497 Americas sales and marketing employees as of December 31, 2015 versus 450 as of December 31, 2014) and (ii) $8.6 million of higher travel, consulting and advertising and promotion costs in support of our business growth. During the year ended December 31, 2015, currency fluctuations resulted in approximately $4.7 million of net favorable foreign currency impact on our Americas sales and marketing expenses primarily due to the generally stronger U.S. dollar relative to the Brazilian real and Canadian dollar during the year ended December 31, 2015 compared to the year ended December 31, 2014. Over the past several years, we have been investing in our Americas sales and marketing initiatives to further increase our revenue. These investments have included the hiring of additional headcount and new product innovation efforts. Although we anticipate that we will continue to invest in Americas sales and marketing initiatives, we believe our Americas sales and marketing expenses as a percentage of revenues will remain at approximately current levels over the next year or two but should ultimately decrease as we continue to grow our business.
EMEA Sales and Marketing Expenses. The decrease in our EMEA sales and marketing expenses was primarily due to $4.5 million of lower professional fees primarily due to the termination of certain contracts during 2014. During the year ended December 31, 2015, the impact of foreign currency fluctuations resulted in approximately $8.3 million of net favorable foreign currency impact on our EMEA sales and marketing expenses primarily due to the generally stronger U.S. dollar relative to the British pound and Euro compared to the year ended December 31, 2014. Over the past several years, we have been investing in our EMEA sales and marketing initiatives to further increase our revenue. These investments have included the hiring of additional headcount and new product innovation efforts and, as a result, our EMEA sales and marketing expenses as a percentage of revenues have increased. We expect our EMEA sales and marketing expenses to further increase as a result of the TelecityGroup acquisition. Although we anticipate that we will continue to invest in EMEA sales and marketing initiatives, including the integration of TelecityGroup, we believe our EMEA sales and marketing expenses as a percentage of revenues will ultimately decrease as we continue to grow our business beyond 2016.

Asia-Pacific Sales and Marketing Expenses. Asia-Pacific sales and marketing expenses for the year ended December 31, 2015 included $2.2 million of sales and marketing expenses attributable to our acquisition of Bit-isle, which closed in November 2015. Excluding Bit-isle, Asia-Pacific sales and marketing expenses were $49.6 million for the year ended December 31, 2015 compared to $43.9 million for the year ended December 31, 2014. The increase in our Asia-Pacific sales and marketing expenses, excluding Bit-isle, was primarily due to $3.6 million of higher compensation costs, including sales compensation, general salaries, bonuses, commission and stock-based compensation as a result of business and headcount growth (183 Asia-Pacific sales and marketing employees, excluding Bit-isle employees, versus 155 as of December 31, 2014). During the year ended December 31, 2015, the impact of foreign currency fluctuations resulted in approximately $3.6 million of net favorable impact on our Asia-Pacific sales and marketing expenses primarily due to a generally stronger U.S. dollar relative to the Australian dollar, Japanese yen and Singapore dollar during the year ended December 31, 2015 compared to the year ended December 31, 2014. Over the past several years, we have been investing in our Asia-Pacific sales and marketing initiatives to further increase our revenue. These investments have included the hiring of additional headcount and new product innovation efforts and, as a result, our Asia-Pacific sales and marketing expenses have increased. We expect our APAC sales and marketing expenses to further increase as a result of the Bit-Isle acquisition. Although we anticipate that we will continue to invest in Asia-Pacific sales and marketing initiatives, including the integration of Bit-isle, we believe our Asia-Pacific sales and marketing expenses as a percentage of revenues will ultimately decrease as we continue to grow our business.

Americas General and Administrative Expenses. The increase in our Americas general and administrative expenses was primarily due to (i) $15.0 million of higher compensation costs, including general salaries, bonuses and stock-based compensation as a result of headcount growth (800 Americas general and administrative employees as of December 31, 2015 versus 731 as of December 31, 2014), (ii) $17.0 million of higher depreciation expenses primarily associated with the implementation of the Oracle R12 ERP system and certain systems to support the REIT conversion and (iii) $10.9 million of higher office expenses, travel, entertainment, and rent and facility costs, in support of our business growth, partially offset by an $11.3 million reduction in professional fees related to our REIT conversion as compared to those incurred during the year ended December 31, 2014. During the year ended December 31, 2015, currency fluctuations resulted in approximately $3.2 million of net favorable foreign currency impact on our Americas general and administrative expenses primarily due to the generally stronger U.S. dollar relative to the Brazilian real and Canadian dollar during the year ended December 31, 2015 compared to the year ended December 31, 2014. Over the course of the past year, we have been investing in our Americas general and administrative functions to scale this region effectively for growth, which has included additional investments into improving our back office systems. We expect our current efforts to improve our back office systems will continue over the next several years. Going forward, although we are carefully monitoring our spending, we expect Americas general and administrative expenses to increase as we continue to further scale our operations to support our growth, including these investments in our back office systems and maintaining our REIT qualification.
EMEA General and Administrative Expenses. The increase in our EMEA general and administrative expenses was primarily due to (i) approximately $4.2 million of higher compensation costs, including general salaries, bonuses and stock-based

48


compensation as a result of headcount growth (420 EMEA general and administrative employees as of December 31, 2015 versus 353 as of December 31, 2014), (ii) $4.3 million of higher depreciation expenses due to implementation of the Oracle R12 ERP system and certain systems to support the REIT conversion and (iii) $2.8 million of higher consulting costs primarily due to integration efforts in connection with our acquisition of TelecityGroup as well as an increase in net losses related to cash flow hedging derivatives. During the year ended December 31, 2015, the impact of foreign currency fluctuations resulted in approximately $7.8 million of net favorable foreign currency impact on our EMEA general and administrative expenses primarily due to the generally stronger U.S. dollar relative to the British pound and Euro during the year ended December 31, 2015 compared to the year ended December 31, 2014. Going forward, although we are carefully monitoring our spending, we expect our EMEA general and administrative expenses to increase in future periods as a result of our acquisition of TelecityGroup and as we continue to scale our operations to support our growth; however, as a percentage of revenues, we generally expect them to decrease.
Asia-Pacific General and Administrative Expenses. Asia-Pacific general and administrative expenses for the year ended December 31, 2015 included $5.8 million of general and administrative expenses attributable to our acquisition of Bit-isle, which closed on November 2, 2015. Excluding general and administrative expenses attributable to Bit-isle, Asia-Pacific general and administrative expenses for the year ended December 31, 2015 were $47.3 million compared to $42.5 million for the year ended December 31, 2014. Excluding general and administrative expenses attributable to Bit-isle, the increase in our Asia-Pacific general and administrative expenses was primarily due to a $2.2 million increase in consulting costs, legal fees and other costs for tax-related matters as well as higher compensation costs, including general salaries, bonuses and stock-based compensation as a result of headcount growth (266 Asia-Pacific general and administrative employees, excluding Bit-isle employees, as of December 31, 2015 versus 224 as of December 31, 2014). During the year ended December 31, 2015, the impact of foreign currency fluctuations resulted in approximately $3.4 million of net favorable impact on our Asia-Pacific general and administrative expenses primarily due to a generally stronger U.S. dollar relative to the Australian dollar, Japanese yen and Singapore dollar compared to the year ended December 31, 2014. Going forward, although we are carefully monitoring our spending, we expect Asia-Pacific general and administrative expenses to increase as a result of our acquisition of Bit-isle and as we continue to scale our operations to support our growth; however, as a percentage of revenues, we generally expect them to decrease.
Acquisition Costs.  During the year ended December 31, 2015, we recorded acquisition costs totaling $41.7 million primarily attributed to the EMEA region, and to a lesser degree, to the Asia-Pacific region. During the year ended December 31, 2014, we recorded acquisition costs totaling $2.5 million primarily attributed to the EMEA region.

Americas Income from Operations. The increase in our Americas income from operations was due to higher revenues as result of our IBX data center expansion activity and organic growth as described above, partially offset by higher operating expenses as a percentage of revenues primarily attributable to higher compensation and other headcount related expenses to support our growth.
EMEA Income from Operations. The increase in our EMEA income from operations was primarily due to higher revenues as a result of our IBX data center expansion activity and organic growth as described above. During the year ended December 31, 2015, currency fluctuations resulted in approximately $25.6 million of net unfavorable foreign currency impact on our EMEA income from operations primarily due to the generally stronger U.S. dollar relative to the British pounds and Euro during the year ended December 31, 2015 compared to the year ended December 31, 2014.
Asia-Pacific Income from Operations. The increase in our Asia-Pacific income from operations was primarily due to higher revenues as a result of our IBX data center expansion activity and organic growth as described above, partially offset by higher operating expenses as a percentage of revenues primarily attributable to higher compensation and other headcount related expenses and higher professional fees to support our growth. During the year ended December 31, 2015, currency fluctuations resulted in approximately $17.5 million of net unfavorable foreign currency impact on our Asia-Pacific income from operations primarily

49


due to the generally stronger U.S. dollar relative to the Australian dollar, Japanese yen and Singapore dollar during the year ended December 31, 2015 compared to the year ended December 31, 2014.
Interest Income. Interest income was $3.6 million and $2.9 million for the years ended December 31, 2015 and 2014, respectively. The average yield for the year ended December 31, 2015 was 0.38% versus 0.33% for the year ended December 31, 2014. We expect our interest income to remain at these low levels for the foreseeable future due to the impact of a continued low interest rate environment and a portfolio more weighted towards short-term securities and U.S. government securities in order to satisfy REIT compliance requirements.
Interest Expense.  Interest expense increased to $299.1 million for the year ended December 31, 2015 from $270.6 million for the year ended December 31, 2014. This increase in interest expense was primarily due to the full impact recognized for the year ended December 31, 2015 of our $1.25 billion of senior notes issued in November 2014, the $0.5 billion Term loan A we borrowed in December 2014 under our senior credit facility and $18 million of higher interest expense from various capital lease and other financing obligations to support our expansion projects, which was partially offset by the redemption of our 7.00% senior notes in December 2014, the settlement of the 3.00% convertible notes and the partial redemption of the 4.75% convertible notes in June 2014. During the years ended December 31, 2015 and 2014, we capitalized $10.9 million and $19.0 million, respectively, of interest expense to construction in progress. Going forward, we expect to incur higher interest expense as we recognize the full impact of our $1.1 billion of senior notes issued in December 2015 and the full impact of financing our acquisition of Bit-isle as well as the impact of approximately $0.7 billion of borrowings under our Term loan B commitments under our senior credit facility that we completed in January 2016. We may also incur additional indebtedness to support our growth, resulting in higher interest expense.
Other Income (Expense). We recorded net expense of $60.6 million and net income of $0.1 million for the years December 31, 2015 and 2014, respectively, primarily due to foreign currency exchange gains and losses during the periods. The expense recorded in 2015 is primarily attributed to foreign currency losses to fund the TelecityGroup acquisition purchase price.
Loss on Debt Extinguishment. During the year ended December 31, 2015, we recorded a $0.3 million loss on debt extinguishment which was attributable to partial conversions of our 4.75% convertible subordinated notes in December 2015. During the year ended December 31, 2014, we recorded a $157.0 million loss on debt extinguishment, of which $51.2 million was attributable to the exchanges of the 3.00% convertible subordinated notes and 4.75% convertible subordinated notes, $103.3 million was attributable to the redemption of our $750.0 million 7.00% senior notes and $2.5 million was attributable to the prepayment and termination of our $750.0 million multicurrency credit facility. For additional information, see “Loss on Debt Extinguishment” in Note 9 of Notes to Consolidated Financial Statements in Item 8 of this Annual Report on Form 10-K.
Income Taxes. Effective January 1, 2015, we have operated as a REIT for federal income tax purposes. As a REIT, we are generally not subject to U.S. income taxes on taxable income distributed to our stockholders. We distributed the entire taxable income generated by the operations of our REIT and its QRSs for the tax year ending December 31, 2015. As such, no provision for U.S. federal income taxes for the REIT and its QRSs has been included in the accompanying consolidated financial statements for the year ended December 31, 2015.
We have made TRS elections for some of our subsidiaries in and outside the U.S. In general, a TRS may provide services that would otherwise be considered impermissible for REITs to provide and may hold assets that REITs cannot hold directly. U.S. income taxes for the TRS entities located in the U.S. and foreign income taxes for our foreign operations regardless of whether the foreign operations are operated as a QRS or TRS were accrued, as necessary, for the year ended December 31, 2015.
For the years ended December 31, 2015 and 2014, we recorded $23.2 million and $345.5 million of income tax expenses, respectively. We recognized a significantly lower income tax provision in 2015 as compared to the income tax provision in 2014 primarily due to the de-recognition, in 2014, of the deferred tax assets and liabilities of our U.S. operations upon conversion to a REIT. As a REIT, we are entitled to a deduction for dividends paid, resulting in a substantial reduction of U.S. income tax expense. Substantially all of our income tax expense for 2015 is for foreign income taxes incurred by our foreign subsidiaries and U.S. income tax incurred by our U.S. TRSs.
The $345.5 million of income tax expense recorded during the year ended December 31, 2014 was primarily attributable to the statutory tax rate change due to our REIT conversion, which resulted in a $324.1 million domestic deferred tax assets write-off. In connection with the formal approval of our conversion to a REIT by our Board of Directors in December 2014, we reassessed, in the fourth quarter of 2014, the deferred tax assets and liabilities of our U.S. operations to be included in the REIT structure. The reevaluation resulted in de-recognizing the deferred tax assets and liabilities of our REIT’s U.S. operations, excluding the deferred tax liabilities associated with the depreciation and amortization recapture expected in 2015. The de-recognition of the deferred tax

50


assets and liabilities of our REIT’s U.S. operations occurred because the expected recovery or settlement of the related assets and liabilities will not result in deductible or taxable amounts in any post-REIT conversion periods. The deferred tax assets and liabilities associated with our foreign operations, regardless of whether such foreign operations were part of the REIT conversion, are not subject to the de-recognition assessment. We generally do not expect our occasional sale of assets to result in a material tax liability.
Our effective tax rates were 11.0% and 407.7%, respectively, for the years ended December 31, 2015 and 2014. Our effective tax rate for the year ended December 31, 2014 was primarily due to tax expense attributable to the $324.1 million domestic deferred tax assets write-off as a result of our REIT conversion. Excluding this tax expense, our effective tax rate would have been 25.2% for the year ended December 31, 2014. Due to our REIT conversion, we are entitled to a deduction for dividends paid, which results in a substantial reduction of U.S income tax expense. As a REIT, substantially all of our income tax expense is the foreign income tax incurred by our foreign subsidiaries and the U.S. income tax expense incurred by our U.S. TRSs. Assuming no material changes to tax rules and regulations, as a REIT we expect our effective long-term world-wide cash tax rate to remain in the range of 10% to 15%.
We recorded excess income tax benefits of $30,000 and $18.6 million during the years ended December 31, 2015 and 2014, respectively, in our consolidated balance sheets.
Adjusted EBITDA. Adjusted EBITDA is a key factor in how we assess the performance of our segments, measure the operational cash generating abilities of our segments and develop regional growth strategies such as IBX data center expansion decisions. We define adjusted EBITDA as income or loss from operations plus depreciation expense, amortization expense, accretion expense, stock-based compensation expense, restructuring charges, impairment charges and acquisition costs. See "Non-GAAP Financial Measures" below for more information about adjusted EBITDA and a reconciliation of adjusted EBITDA to income or loss from operations. Periodically, we enter into new lease agreements or amend existing lease agreements. To the extent we conclude that a lease is an operating lease, the rent expense may decrease our adjusted EBITDA whereas to the extent we conclude that a lease is a capital or financing lease, and this lease was previously reported as an operating lease, this outcome may increase our adjusted EBITDA. Our adjusted EBITDA for the years ended December 31, 2015 and 2014 was split among the following geographic regions (dollars in thousands):

Americas Adjusted EBITDA. The increase in our Americas adjusted EBITDA was due to higher revenues as result of our IBX data center expansion activity and organic growth as described above, partially offset by higher adjusted operating expenses as a percentage of revenues primarily attributable to higher compensation and other headcount related expenses to support our growth. During the year ended December 31, 2015, currency fluctuations resulted in approximately $12.2 million of net unfavorable foreign currency impact on our Americas adjusted EBITDA primarily due to the generally stronger U.S. dollar relative to the Brazilian real and Canadian dollar during the year ended December 31, 2015 compared to the year ended December 31, 2014.
EMEA Adjusted EBITDA. The increase in our EMEA adjusted EBITDA was primarily due to higher revenues as a result of our IBX data center expansion activity and organic growth as described above. During the year ended December 31, 2015, currency fluctuations resulted in approximately $45.4 million of net unfavorable foreign currency impact on our EMEA adjusted EBITDA primarily due to the generally stronger U.S. dollar relative to the British pounds and Euro during the year ended December 31, 2015 compared to the year ended December 31, 2014.
Asia-Pacific Adjusted EBITDA. The increase in our Asia-Pacific adjusted EBITDA was primarily due to higher revenues as a result of our IBX data center expansion activity and organic growth as described above, partially offset by higher adjusted operating expenses as percentages of revenues primarily attributable to higher compensation and other headcount related expenses and higher professional fees to support our growth. During the year ended December 31, 2015, currency fluctuations resulted in approximately $26.1 million of net unfavorable foreign currency impact on our Asia-Pacific adjusted EBITDA primarily due to the generally stronger U.S. dollar relative to the Australian dollar, Japanese yen and Singapore dollar during the year ended December 31, 2015 compared to the year ended December 31, 2014.

Americas Revenues. During the years ended December 31, 2014 and 2013, our revenues from the United States, the largest revenue contributor in the Americas region for the periods, represented approximately 91% of the regional revenues. Growth in Americas revenues was primarily due to (i) $38.3 million of revenue generated from our recently-opened IBX data centers and IBX data center expansions in the Atlanta, Chicago, Dallas, Miami, New York and Sao Paolo metro areas and (ii) an increase in orders from both our existing customers and new customers during the period as reflected in the growth in our utilization rate, as discussed above. During the year ended December 31, 2014, currency fluctuations resulted in approximately $22.1 million of unfavorable foreign currency impact on our Americas revenues primarily due to the generally stronger U.S. dollar relative to the Brazilian real and Canadian dollar during the year ended December 31, 2014 compared to the year ended December 31, 2013. We expect that our Americas revenues will continue to grow in future periods as a result of continued growth in the recently-opened IBX data centers and additional IBX data center expansions currently taking place in the Dallas, New York, Philadelphia, Rio de Janeiro, Seattle, Silicon Valley, Toronto and Washington, D.C. metro areas, which opened during 2015.
EMEA Revenues.  During the years ended December 31, 2014 and 2013, our revenues from the United Kingdom, the largest revenue contributor in the EMEA region for the periods, represented approximately 36% of the regional revenues. Our EMEA revenue growth was due to (i) $20.0 million of revenue generated from our recently-opened IBX data centers and IBX data center expansions in the Amsterdam and Frankfurt metro areas and (ii) an increase in orders from both our existing customers and new customers during the period as reflected in the growth in our utilization rate, as discussed above, in both our new and existing IBX data centers. During the year ended December 31, 2014, currency fluctuations resulted in approximately $11.1 million of favorable foreign currency impact on our EMEA revenues primarily due to the generally weaker U.S. dollar relative to the British pound, Euro and Swiss franc during the year ended December 31, 2014 compared to the year ended December 31, 2013. We expect that our EMEA revenues will continue to grow in future periods as a result of continued growth in recently-opened IBX data centers and an additional IBX data center expansion currently taking place in the Amsterdam, Frankfurt, London and Paris metro areas, which opened during 2015.
Asia-Pacific Revenues.  Our revenues from Singapore, the largest revenue contributor in the Asia-Pacific region, represented approximately 38% and 36%, respectively, of the regional revenues for the years ended December 31, 2014 and 2013. Our Asia-Pacific revenue growth was due to (i) $53.4 million of revenue generated from our recently-opened IBX data centers and IBX data center expansions in the Hong Kong, Melbourne, Osaka, Singapore, Sydney and Tokyo metro areas and (ii) an increase in

52


orders from both our existing customers and new customers during the period as reflected in the growth in our utilization rate, as discussed above, in both our new and existing IBX data centers. During the year ended December 31, 2014, currency fluctuations resulted in approximately $13.7 million of net unfavorable foreign currency impact on our Asia-Pacific revenues primarily due to the generally stronger U.S. dollar relative to the Australian dollar, Japanese yen and Singapore dollar during the year ended December 31, 2014 compared to the year ended December 31, 2013. We expect that our Asia-Pacific revenues will continue to grow in future periods as a result of continued growth in these recently-opened IBX data center expansions and additional expansions currently taking place in the Hong Kong, Singapore and Tokyo metro areas, which opened during 2015 or are expected to open during 2016.

Americas Cost of Revenues.  Our Americas cost of revenues for the years ended December 31, 2014 and 2013 included $218.4 million and $216.6 million, respectively, of depreciation expense. Excluding depreciation expense, the increase in our Americas cost of revenues was primarily due to (i) $17.7 million of higher utilities and repair and maintenance expense in support of our business growth, (ii) $8.7 million of higher compensation costs, including general salaries, bonuses, stock-based compensation and headcount growth (941 employees included in Americas cost of revenues as of December 31, 2014 versus 894 as of December 31, 2013), (iii) $8.1 million of higher costs associated with equipment resales to support the growth of non-recurring revenues and (iv) $3.9 million of higher accretion expenses as a result of the reversal of asset retirement obligations during the year ended December 31, 2013 associated with the execution of certain lease amendments, partially offset by $12.9 million of lower rent and facility costs primarily as a result of either certain leases no longer being subject to operating lease treatment or the purchase of previously-leased sites. During the year ended December 31, 2014, currency fluctuations resulted in approximately $16.3 million of favorable foreign currency impact on our Americas cost of revenues primarily due to the generally stronger U.S. dollar relative to the Brazilian real and Canadian dollar during the year ended December 31, 2014 compared to the year ended December 31, 2013.
EMEA Cost of Revenues. EMEA cost of revenues for the years ended December 31, 2014 and 2013 included $97.8 million and $77.9 million, respectively, of depreciation expense. Growth in depreciation expense was primarily due to our IBX data center expansion activity. Excluding depreciation expense, the increase in our EMEA cost of revenues was primarily due to (i) $29.9 million of higher utility costs, repair and maintenance, professional fees and rent and facility costs in support of our revenue growth, (ii) $7.4 million of higher compensation, including general salaries, bonuses, stock-based compensation and headcount growth (473 employees included in EMEA cost of revenues as of December 31, 2014 versus 396 as of December 31, 2013) and (iii) $5.8 million of higher costs associated with equipment resales, bandwidth and other customer services in support of our non-recurring revenues growth. During the year ended December 31, 2014, the impact of foreign currency fluctuations resulted in approximately $4.4 million of unfavorable foreign currency impact on our EMEA cost of revenues primarily due to the generally

weaker U.S. dollar relative to the British pound, Euro and Swiss franc during the year ended December 31, 2014 compared to the year ended December 31, 2013.
Asia-Pacific Cost of Revenues.  Asia-Pacific cost of revenues for the years ended December 31, 2014 and 2013 included $101.4 million and $82.6 million, respectively, of depreciation expense. Growth in depreciation expense was primarily due to our IBX data center expansion activity. Excluding depreciation expense, the increase in Asia-Pacific cost of revenues was primarily due to (i) $13.7 million in higher utility costs, repairs and maintenance costs, as well as rent and facility costs in support of our revenue growth; (ii) $2.7 million of higher compensation costs, including general salaries, bonuses, stock-based compensation and headcount growth (342 employees included in Asia-Pacific cost of revenues as of December 31, 2014 versus 289 as of December 31, 2013) and (iii) $3.3 million of higher costs associated with equipment resales in support of our non-recurring revenues growth. During the year ended December 31, 2014, currency fluctuations resulted in approximately $8.4 million of net favorable foreign currency impact on our Asia-Pacific cost of revenues primarily due to the generally stronger U.S. dollar relative to the Australian dollar, Japanese yen and Singapore dollar during the year ended December 31, 2014 compared to the year ended December 31, 2013.

Americas Sales and Marketing Expenses. The increase in our Americas sales and marketing expenses was primarily due to (i) $21.6 million of higher compensation costs, including sales compensation, general salaries, bonuses, commission, stock-based compensation as a result of headcount growth (450 Americas sales and marketing employees as of December 31, 2014 versus 395 as of December 31, 2013) and (ii) $5.3 million of higher travel, advertising and promotion costs in support of our business growth. During the year ended December 31, 2014, currency fluctuations resulted in approximately $2.5 million of favorable foreign currency impact on our Americas sales and marketing expenses primarily due to the generally stronger U.S. dollar relative to the Brazilian real and Canadian dollar during the year ended December 31, 2014 compared to the year ended December 31, 2013.
EMEA Sales and Marketing Expenses. The increase in our EMEA sales and marketing expenses was primarily due to $8.2 million of higher compensation costs, including sales compensation, general salaries, bonuses and stock-based compensation expense as a result of business growth, which incorporates a change in our sales commission practices whereby our sales commission accrual will occur when sales orders are booked versus when the sales orders are billed. For the year ended December 31, 2014, the impact of foreign currency fluctuations on our EMEA sales and marketing expenses was not significant when compared to average exchange rates of the year ended December 31, 2013.
Asia-Pacific Sales and Marketing Expenses. The increase in our Asia-Pacific sales and marketing expenses was primarily due to $9.5 million of higher compensation costs, including sales compensation, general salaries, bonuses, commission, stock-based compensation as a result of business and headcount growth (155 Asia-Pacific sales and marketing employees as of December 31,

54


2014 versus 120 as of December 31, 2013), which incorporates a change in our sales commission practices whereby our sales commission accrual will occur when sales orders are booked versus when the sales orders are billed. For the year ended December 31, 2014, the impact of foreign currency fluctuations to our Asia-Pacific sales and marketing expenses was not significant when compared to average exchange rates of the year ended December 31, 2013.

Americas General and Administrative Expenses.  The increase in our Americas general and administrative expenses was primarily due to (i) $24.9 million of higher compensation costs, including general salaries, bonuses, stock-based compensation, as a result of headcount growth (731 Americas general and administrative employees as of December 31, 2014 versus 695 as of December 31, 2013) and the exercise of the ALOG stock options, (ii) $15.2 million of higher professional fees, recruiting, training and travel expenses to support the REIT conversion, (iii) $5.4 million of higher depreciation expenses primarily due to implementation of our Oracle R12 ERP system and certain systems to support the REIT conversion and (iv) $4.0 million higher of office expenses in support of our business growth. During the year ended December 31, 2014, currency fluctuations resulted in approximately $2.4 million of favorable foreign currency impact on our Americas general and administrative expenses primarily due to the generally stronger U.S. dollar relative to the Brazilian real and Canadian dollar during the year ended December 31, 2014 compared to the year ended December 31, 2013.
EMEA General and Administrative Expenses. The increase in our EMEA general and administrative expenses was primarily due to (i) approximately $3.7 million of higher compensation costs, including general salaries, bonuses and headcount growth (353 EMEA general and administrative employees as of December 31, 2014 versus 301 as of December 31, 2013) and (ii) $2.5 million of higher depreciation expenses due to implementation of the Oracle R12 ERP system and certain systems to support the REIT conversion. During the year ended December 31, 2014, the impact of foreign currency fluctuations resulted in approximately $2.0 million of unfavorable foreign currency impact on our EMEA general and administrative expenses primarily due to the generally weaker U.S. dollar relative to the British pound, Euro and Swiss franc during the year ended December 31, 2014 compared to the year ended December 31, 2013.
Asia-Pacific General and Administrative Expenses. The increase in our Asia-Pacific general and administrative expenses was primarily due to $4.2 million of higher compensation costs, including general salaries, bonuses and headcount growth (224 Asia-Pacific general and administrative employees as of December 31, 2014 versus 208 as of December 31, 2013). For the year ended December 31, 2014, the impact of foreign currency fluctuations on our Asia-Pacific general and administrative expenses was not significant when compared to average exchange rates of the year ended December 31, 2013.
Restructuring Charges.  During the year ended December 31, 2014, we did not record any restructuring charges. During the year ended December 31, 2013, we recorded a $4.8 million reversal of the restructuring charge accrual for our excess space in the

55


New York 2 IBX data center as a result of our decision to purchase this property and utilize the space. See “Restructuring Charges” in Note 17 of Notes to Consolidated Financial Statements in Item 8 of this Annual Report on Form 10-K.
Acquisition Costs.  During the year ended December 31, 2014, we recorded acquisition costs totaling $2.5 million primarily attributed to the EMEA region. During the year ended December 31, 2013, we recorded acquisition costs totaling $10.9 million primarily attributed to our Americas and EMEA regions.

Americas Income from Operations. The increase in our Americas income from operations was due to higher revenues as result of our IBX data center expansion activity and organic growth as described above, partially offset by higher operating expenses as a percentage of revenues primarily attributable to higher compensation expense and higher professional fees to support our growth.
EMEA Income from Operations. The increase in our EMEA income from operations was primarily due to higher revenues as a result of our IBX data center expansion activity and organic growth as described above, partially offset by higher operating expenses as a percentage of revenues primarily attributable to higher compensation expense and higher professional fees to support our growth. During the year ended December 31, 2014, currency fluctuations resulted in approximately $3.3 million of net favorable foreign currency impact on our EMEA income from operations primarily due to the generally weaker U.S. dollar relative to the Euro and Swiss franc during the year ended December 31, 2014 compared to the year ended December 31, 2013.
Asia-Pacific Income from Operations. The increase in our Asia-Pacific income from operations was primarily due to higher revenues as a result of our IBX data center expansion activity and organic growth as described above, partially offset by higher operating expenses as a percentage of revenues primarily attributable to higher compensation expense and higher professional fees to support our growth. During the year ended December 31, 2014, currency fluctuations resulted in approximately $3.2 million of net unfavorable foreign currency impact on our Asia-Pacific income from operations primarily due to the generally stronger U.S. dollar relative to the Australian dollar, Japanese yen and Singapore dollar during the year ended December 31, 2014 compared to the year ended December 31, 2013.
Interest Income. Interest income was $2.9 million and $3.4 million for the years ended December 31, 2014 and 2013, respectively. The average yield for the year ended December 31, 2014 was 0.33% versus 0.32% for the year ended December 31, 2013.
Interest Expense.  Interest expense increased to $270.6 million for the year ended December 31, 2014 from $248.8 million for the year ended December 31, 2013. This increase in interest expense was primarily due to the impact of our $1.25 billion senior notes offering in November 2014 and $29.8 million of higher interest expense from various capital lease and other financing obligations to support our expansion projects, which was offset by the redemption of our 7.00% senior notes in December 2014, the settlement of the 3.00% convertible notes, the partial redemption of the 4.75% convertible notes in June 2014 and more capitalized interest expense. During the years ended December 31, 2014 and 2013, we capitalized $19.0 million and $10.6 million, respectively, of interest expense to construction in progress.
Other Income (Expense). We recorded $0.1 million and $5.3 million, respectively, of other income for the years ended December 31, 2014 and 2013, primarily due to foreign currency exchange gains (losses) during the periods.
Loss on Debt Extinguishment. During the year ended December 31, 2014, we recorded a $157.0 million loss on debt extinguishment, of which $51.2 million was attributable to the exchanges of the 3.00% convertible subordinated notes and 4.75% convertible subordinated notes, $103.3 million was attributable to the redemption of our $750.0 million 7.00% senior notes and $2.5 million was attributable to the prepayment and termination of our $750.0 million multicurrency credit facility. During the year ended December 31, 2013, we recorded a $108.5 million loss on debt extinguishment, of which $93.6 million was attributable

56


to the redemption of our $750 million 8.125% senior notes, $13.2 million was attributable to the extinguishment of the financing liabilities for our London 4 and 5 IBX data centers and $1.7 million was attributable to an amendment of our New York 5 and 6 IBX lease. For additional information, see “Loss on Debt Extinguishment” in Note 9 of Notes to Consolidated Financial Statements in Item 8 of this Annual Report on Form 10-K.
Income Taxes. During the year ended December 31, 2014, we recorded $345.5 million of income tax expense. The income tax expense recorded during the year ended December 31, 2014 was primarily attributable to the statutory tax rate change due to our anticipated REIT conversion, which resulted in a $324.1 million domestic deferred tax assets write-off. In connection with the formal approval of our conversion to a REIT by our Board of Directors in December 2014, we reassessed, in the fourth quarter of 2014, the deferred tax assets and liabilities of our U.S. operations to be included in the REIT structure. The reevaluation resulted in de-recognizing the deferred tax assets and liabilities of our REIT’s U.S. operations, excluding the deferred tax liabilities associated with the depreciation and amortization recapture expected in 2015. The de-recognition of the deferred tax assets and liabilities of our REIT’s U.S. operations occurred because the expected recovery or settlement of the related assets and liabilities will not result in deductible or taxable amounts in any post-REIT conversion periods. The deferred tax assets and liabilities associated with our foreign operations, regardless of whether such foreign operations are part of the REIT conversion, are not subject to the de-recognition assessment. In addition, we generally do not expect our occasional sale of assets to result in a material tax liability. As of December 31, 2014, we had a net deferred tax liability of approximately $52.2 million for our domestic operations, which included approximately $82.5 million of deferred tax liabilities associated with the depreciation and amortization recapture.
During the year ended December 31, 2013, we recorded $16.2 million of income tax expense. The income tax expense recorded during the year ended December 31, 2013 was primarily attributable to our foreign operations, as we incurred losses in our domestic operations during the period. Our effective tax rates were 407.7% and 14.4%, respectively, for the years ended December 31, 2014 and 2013. The increase in our effective tax rate was primarily due to tax expense attributable to the domestic deferred tax assets write-off as a result of our REIT conversion. Excluding this tax expense, our effective tax rate would have been 25.2% for the year ended December 31, 2014.
During the year ended December 31, 2013, we utilized all of our federal net operating losses free of Section 382 limitations in the U.S. for which a deferred tax asset had been previously recognized and all of our windfall tax losses in the U.S. for which a deferred tax asset had not been previously recognized. We recorded excess income tax benefits of $18.6 million and $25.6 million during the year ended December 31, 2014 and 2013, respectively, in our consolidated balance sheet.
To better align our EMEA corporate structure and intercompany relationship with the nature of our business activities and regional centralization, we commenced certain reorganization activities during the fourth quarter of 2012 in the EMEA region. The new organizational structure centralized the majority of our EMEA business management activities in the Netherlands effective July 1, 2013. In December 2013, our Dutch subsidiaries that were created to carry-out EMEA’s centralized management activities received favorable rulings from the Dutch Tax Authorities effective July 1, 2013. The rulings acknowledge the reorganization and agree to a lower level of earnings by our Dutch subsidiaries subject to tax in the Netherlands. The rulings also require both the Dutch Tax Authorities and our Dutch subsidiaries to revisit and renew the agreement in five years from the effective date. As a result, we expect our overall effective tax rate will be lower in subsequent periods as the new structure takes full effect.
Adjusted EBITDA. Adjusted EBITDA is a key factor in how we assess the performance of our segments, measure the operational cash generating abilities of our segments and develop regional growth strategies such as IBX data center expansion decisions. We define adjusted EBITDA as income or loss from operations plus depreciation expense, amortization expense, accretion expense, stock-based compensation, restructuring charges, impairment charges and acquisition costs. See "Non-GAAP Financial Measures" below for more information about adjusted EBITDA and a reconciliation of adjusted EBITDA to income or loss from operations. Periodically, we enter into new lease agreements or amend existing lease agreements. To the extent we conclude that a lease is an operating lease, the rent expense may decrease our adjusted EBITDA whereas to the extent we conclude that a lease is a capital or financing lease, and this lease was previously reported as an operating lease, this outcome may increase our adjusted EBITDA. Our adjusted EBITDA for the years ended December 31, 2014 and 2013 was split among the following geographic regions (dollars in thousands):

Americas Adjusted EBITDA. The increase in our Americas adjusted EBITDA was due to higher revenues as result of our IBX data center expansion activity and organic growth as described above, partially offset by higher adjusted operating expenses as a percentage of revenues primarily attributable to higher compensation expense and higher professional fees to support our growth. During the year ended December 31, 2014, currency fluctuations resulted in approximately $8.1 million of unfavorable foreign currency impact on our Americas adjusted EBITDA primarily due to the generally stronger U.S. dollar relative to the Brazilian real and Canadian dollar during the year ended December 31, 2014 compared to the year ended December 31, 2013.
EMEA Adjusted EBITDA. The increase in our EMEA adjusted EBITDA was primarily due to higher revenues as a result of our IBX data center expansion activity and organic growth as described above, partially offset by higher adjusted operating expenses as a percentage of revenues primarily attributable to higher compensation expense and higher professional fees to support our growth. During the year ended December 31, 2014, currency fluctuations resulted in approximately $4.9 million of net favorable foreign currency impact on our EMEA adjusted EBITDA primarily due to the generally weaker U.S. dollar relative to the Euro and Swiss franc during the year ended December 31, 2014 compared to the year ended December 31, 2013.
Asia-Pacific Adjusted EBITDA. The increase in our Asia-Pacific adjusted EBITDA was primarily due to higher revenues as a result of our IBX data center expansion activity and organic growth as described above, partially offset by higher adjusted operating expenses as a percentage of revenues primarily attributable to higher compensation expense and higher professional fees to support our growth. During the year ended December 31, 2014, currency fluctuations resulted in approximately $7.0 million of net unfavorable foreign currency impact on our Asia-Pacific adjusted EBITDA primarily due to the generally stronger U.S. dollar relative to the Australian dollar, Japanese yen and Singapore dollar during the year ended December 31, 2014 compared to the year ended December 31, 2013.
Non-GAAP Financial Measures
We provide all information required in accordance with generally accepted accounting principles (“GAAP”), but we believe that evaluating our ongoing operating results may be difficult if limited to reviewing only GAAP financial measures. Accordingly, we use non-GAAP financial measures to evaluate our operations.
Non-GAAP financial measures are not a substitute for financial information prepared in accordance with GAAP. Non-GAAP financial measures should not be considered in isolation, but should be considered together with the most directly comparable GAAP financial measures and the reconciliation of the non-GAAP financial measures to the most directly comparable GAAP financial measures. We have presented such non-GAAP financial measures to provide investors with an additional tool to evaluate our operating results in a manner that focuses on what management believes to be our core, ongoing business operations. We believe that the inclusion of these non-GAAP financial measures provides consistency and comparability with past reports and provides a better understanding of the overall performance of the business and ability to perform in subsequent periods. We believe that if we did not provide such non-GAAP financial information, investors would not have all the necessary data to analyze Equinix effectively.
Investors should note that the non-GAAP financial measures used by us may not be the same non-GAAP financial measures, and may not be calculated in the same manner, as those of other companies. Investors should therefore exercise caution when comparing non-GAAP financial measures used by us to similarly titled non-GAAP financial measures of other companies.
Our primary non-GAAP financial measures, adjusted funds from operations (“AFFO”) and adjusted EBITDA, exclude depreciation expense as these charges primarily relate to the initial construction costs of our IBX data centers and do not reflect our current or future cash spending levels to support our business. Our IBX data centers are long-lived assets and have an economic life greater than 10 years. The construction costs of an IBX data center do not recur with respect to such data center, although we may incur initial construction costs in future periods with respect to additional IBX data centers, and future capital expenditures remain minor relative to our initial investment. This is a trend we expect to continue. In addition, depreciation is also based on the

58


estimated useful lives of our IBX data centers. These estimates could vary from actual performance of the asset, are based on historical costs incurred to build out our IBX data centers and are not indicative of current or expected future capital expenditures. Therefore, we exclude depreciation from our operating results when evaluating our operations.
In addition, in presenting AFFO and adjusted EBITDA, we exclude amortization expense related to certain intangible assets, as it represents the amortization of a cost that may not recur and is not meaningful in the evaluation of our current or future operating performance. We exclude accretion expense, both as it relates to asset retirement obligations as well as accrued restructuring charge liabilities, as these expenses represent costs which we believe are not meaningful in evaluating our current operations. We exclude stock-based compensation expense as it represents expense attributed to equity awards that have no current or future cash obligations. As such, we, and many investors and analysts, exclude this stock-based compensation expense when assessing the cash generating performance of our operations. We also exclude restructuring charges. The restructuring charges relate to our decisions to exit leases for excess space adjacent to several of our IBX data centers, which we did not intend to build out, or our decision to reverse such restructuring charges. We also exclude impairment charges related to certain long-lived assets. The impairment charges are related to expense recognized whenever events or changes in circumstances indicate that the carrying amount of long-lived assets are not recoverable. Finally, we exclude acquisition costs from AFFO and adjusted EBITDA. The acquisition costs relate to costs we incur in connection with business combinations. Management believes items such as restructuring charges, impairment charges and acquisition costs are non-core transactions; however, these types of costs may occur in future periods.

Our adjusted EBITDA results have improved each year and in each region in total dollars due to the improved operating results discussed earlier in “Results of Operations”, as well as the nature of our business model consisting of a recurring revenue stream and a cost structure which has a large base that is fixed in nature also discussed earlier in “Overview”.
Funds from Operations (“FFO”) and AFFO
We use FFO and AFFO, which are non-GAAP financial measures commonly used in the REIT industry. FFO is calculated in accordance with the standards established by the National Association of Real Estate Investment Trusts (“NAREIT”). FFO represents net income (loss), excluding gains (losses) from the disposition of real estate assets, depreciation and amortization on real estate assets and adjustments for unconsolidated joint ventures’ and non-controlling interests’ share of these items.
We use AFFO to evaluate our performance on a consolidated basis and as a metric in the determination of employees’ annual bonuses beginning in 2015 and vesting of restricted stock units that were granted in 2015 that have both service and performance conditions. In presenting AFFO, we exclude certain items that we believe are not good indicators of our current or future operating performance. AFFO represents FFO excluding depreciation and amortization expense on non-real estate assets, accretion, stock-based compensation, restructuring charges, impairment charges, acquisition costs, an installation revenue adjustment, a straight-line rent expense adjustment, amortization of deferred financing costs, gains (losses) on debt extinguishment, an income tax expense adjustment, recurring capital expenditures and adjustments for unconsolidated joint ventures’ and non-controlling interests’ share of these items. We include an adjustment for revenue from installation fees, since installation fees are deferred and recognized ratably over the expected life of the installation, although the fees are generally paid in a lump sum upon installation. We include an adjustment for straight-line rent expense on its operating leases, since the total minimum lease payments are recognized ratably over the lease term, although the lease payments generally increase over the lease term. The adjustments for both installation revenue and straight-line rent expense are intended to isolate the cash activity included within the straight-lined or amortized results in the consolidated statement of operations. We exclude the amortization of deferred financing costs as these expenses relate to the initial costs incurred in connection with debt financings that have no current or future cash obligations. We exclude gains (losses) on debt extinguishment since it represents a cost that may not recur and is not a good indicator of our current or future

59


operating performance. We include an income tax expense adjustment, which represents changes in its income tax reserves and valuation allowances that may not recur or may not relate to the current year’s operations. We also excludes recurring capital expenditures, which represent expenditures to extend the useful life of its IBX centers or other assets that are required to support current revenues.

Our AFFO results have improved due to the improved operating results discussed earlier in “Results of Operations,” as well as due to the nature of our business model which consists of a recurring revenue stream and a cost structure which has a large base that is fixed in nature as discussed earlier in “Overview.”
Constant Currency Presentation
Our revenues and certain operating expenses (cost of revenues, sales and marketing and general and administrative expenses) from our international operations have represented and will continue to represent a significant portion of our total revenues and

certain operating expenses. As a result, our revenues and certain operating expenses have been and will continue to be affected by changes in the U.S. dollar against major international currencies such as the Brazilian reals, British pound, Canadian dollar, Euro, Swiss franc, Australian dollar, Chinese Yuan, Hong Kong dollar, Japanese yen and Singapore dollar. In order to provide a framework for assessing how each of our business segments performed excluding the impact of foreign currency fluctuations, we present period-over-period percentage changes in our revenues and certain operating expenses on a constant currency basis in addition to the historical amounts as reported. Presenting constant currency results of operations is a non-GAAP financial measure and is not meant to be considered in isolation or as an alternative to GAAP results of operations. However, we have presented this non-GAAP financial measure to provide investors with an additional tool to evaluate our operating results. To present this information, our current and comparative prior period revenues and certain operating expenses from entities reporting in currencies other than the U.S. dollar are converted into U.S. dollars at constant exchange rates rather than the actual exchange rates in effect during the respective periods (i.e. average rates in effect for the year ended December 31, 2014 are used as exchange rates for the year ended December 31, 2015 when comparing the year ended December 31, 2015 with the year ended December 31, 2014, and average rates in effect for the year ended December 31, 2013 are used as exchange rates for the year ended December 31, 2014 when comparing the year ended December 31, 2014 with the year ended December 31, 2013).

In 2018, as more fully described in Note 12 of the Notes to Consolidated Financial Statements in Item 8 of this Annual Report on Form 10-K, we sold 930,934 shares of our common stock for approximately $388.2 million, net of payment of commissions to the sales agents and estimated equity offering costs under our ATM program launched in 2017 (the "2017 ATM Program"). As of December 31, 2018, no shares remained available for sale under the 2017 ATM Program. In December 2018, we launched another ATM program, under which we may offer and sell from time to time up to an aggregate of $750.0 million of our common stock in "at the market" transactions (the "2018 ATM Program"). As of December 31, 2018, no sales have been made under the 2018 ATM Program.
In July 2018, as more fully described in Note 11 of the Notes to Consolidated Financial Statements in Item 8 of this Annual Report on Form 10-K, we entered into an amendment to our existing credit agreement to add a senior unsecured term loan in an aggregate principal amount of ¥47.5 billion (the "JPY Term Loan"). Concurrent with the closing of our JPY Term Loan, we drew down the full ¥47.5 billion of the JPY Term Loan, or approximately $424.7 million, and prepaid the remaining principal of our existing Japanese Yen Term Loan of ¥43.8 billion, or approximately $391.3 million. We recognized a loss on debt extinguishment of $2.2 million during the third quarter of 2018 in connection therewith.
In April 2018, as more fully described in Note 3 of the Notes to Consolidated Financial Statements in Item 8 of this Annual Report on Form 10-K, we completed the acquisition of Metronode for a cash purchase price of A$1.034 billion or approximately $804.6 million at the exchange rate in effect on April 18, 2018 (the "Metronode Acquisition"). We accounted for this transaction as a business combination using the acquisition method of accounting. The valuation and purchase accounting of this acquisition have not yet been finalized as of December 31, 2018.
In April 2018, as more fully described in Note 3 of the Notes to Consolidated Financial Statements in Item 8 of this Annual Report on Form 10-K, we completed the acquisition of Infomart Dallas for total consideration of approximately $804.0 million (the "Infomart Dallas Acquisition"), consisting of approximately $45.8 million in cash, subject to customary adjustments, and $758.2 million aggregate fair value of 5.000% senior unsecured notes. We accounted for this transaction as a business combination using the acquisition method of accounting. The valuation and purchase accounting of this acquisition have not yet been finalized as of December 31, 2018.
In March 2018, as more fully described in Note 11 of the Notes to Consolidated Financial Statements in Item 8 of this Annual Report on Form 10-K, we issued €750.0 million, or approximately $929.9 million in U.S. dollars, at the exchange rate in effect on March 14, 2018, aggregate principal amount of 2.875% senior notes due March 15, 2024. We incurred debt issuance costs of $11.6 million related to the 2.875% Euro Senior Notes due 2024.


Overview
Equinix provides global data center offerings that protect and connect the world's most valued information assets. Global enterprises, financial services companies and content and network service providers rely upon Equinix's leading insight and data centers around the world for the safehousing of their critical IT equipment and the ability to directly connect to the networks that enable today's information-driven economy. The acquisitions of Infomart Dallas and Metronode expanded our total global footprint to 200 IBX data centers across 52 markets around the world. Equinix offers the following solutions: (i) premium data center colocation, (ii) interconnection and exchange and (iii) outsourced IT infrastructure solutions. As of December 31, 2018, we operated or had partner IBX data centers in Brazil, Canada, Colombia and throughout the U.S. in the Americas region; Bulgaria, Finland, France, Germany, Ireland, Italy, the Netherlands, Poland, Portugal, Spain, Sweden, Switzerland, Turkey, the United Arab Emirates and the United Kingdom in the EMEA region; and Australia, China, Hong Kong, Indonesia, Japan and Singapore in the Asia-Pacific region.

 Our data centers in 52 markets around the world are a global platform, which allows our customers to increase information and application delivery performance while significantly reducing costs. This global platform and the quality of our IBX data centers have enabled us to establish a critical mass of customers. As more customers choose our IBX data centers, it benefits their suppliers and business partners to colocate with us as well, in order to gain the full economic and performance benefits of our offerings. These partners, in turn, pull in their business partners, creating a "marketplace" for their services. Our global platform enables scalable, reliable and cost-effective colocation, interconnection and traffic exchange that lowers overall cost and increases flexibility. Our focused business model is built on our critical mass of customers and the resulting "marketplace" effect. This global platform, combined with our strong financial position, continues to drive new customer growth and bookings.

Historically, our market has been served by large telecommunications carriers who have bundled telecommunications products and services with their colocation offerings. The data center market landscape has evolved to include cloud computing/utility providers, application hosting providers and systems integrators, managed infrastructure hosting providers and colocation providers. More than 350 companies provide data center solutions in the U.S. alone. Each of these data center solutions providers can bundle various colocation, interconnection and network offerings and outsourced IT infrastructure solutions. We are able to offer our customers a global platform that reaches 24 countries with proven operational reliability, improved application performance, network choice and a highly scalable set of offerings.
Our utilization rate represents the percentage of our cabinet space billing versus net sellable cabinet space available, taking into account power limitations. Our utilization rates were approximately 81%, as of December 31, 2018, and 80%, excluding the Verizon Data Center, Paris IBX Data Center, Itconic, Zenium data center and IO acquisitions, as of December 31, 2017. Excluding the impact of IBX data center expansion projects that have opened during the last 12 months, our utilization rate would have increased to approximately 83% as of December 31, 2018. Our cabinet utilization rate varies from market to market among our IBX data centers across the Americas, EMEA and Asia-Pacific regions. We continue to monitor the available capacity in each of our selected markets. To the extent we have limited capacity available in a given market, it may limit our ability for growth in that market. We perform demand studies on an ongoing basis to determine if future expansion is warranted in a market. In addition, power and cooling requirements for most customers are growing on a per unit basis. As a result, customers are consuming an increasing amount of power per cabinet. Although we generally do not control the amount of power our customers draw from installed circuits, we have negotiated power consumption limitations with certain high power-demand customers. This increased power consumption has driven us to build out our new IBX data centers to support power and cooling needs twice that of previous IBX data centers. We could face power limitations in our IBX data centers, even though we may have additional physical cabinet capacity available within a specific IBX data center. This could have a negative impact on the available utilization capacity of a given IBX data center, which could have a negative impact on our ability to grow revenues, affecting our financial performance, operating results and cash flows.
Strategically, we will continue to look at attractive opportunities to grow our market share and selectively improve our footprint and offerings. As was the case with our recent expansions and acquisitions, our expansion criteria will be dependent on a number of factors, including but not limited to demand from new and existing customers, quality of the design, power capacity, access to networks, capacity availability in the current market location, amount of incremental investment required by us in the targeted property, lead-time to break even on a free cash flow basis and in-place customers. Like our recent expansions and acquisitions, the right combination of these factors may be attractive to us. Depending on the circumstances, these transactions may require additional capital expenditures funded by upfront cash payments or through long-term financing arrangements in order to bring these properties up to Equinix standards. Property expansion may be in the form of purchases of real property, long-term leasing arrangements or acquisitions. Future purchases, construction or acquisitions may be completed by us or with partners or potential customers to minimize the outlay of cash, which can be significant.

Our business is based on a recurring revenue model comprised of colocation and related interconnection and managed infrastructure offerings. We consider these offerings recurring because our customers are generally billed on a fixed and recurring basis each month for the duration of their contract, which is generally one to three years in length. Our recurring revenues have comprised more than 90% of our total revenues during the past three years. In addition, during any given quarter of the past three years, more than half of our monthly recurring revenue bookings came from existing customers, contributing to our revenue growth. Our largest customer accounted for approximately 3% of our recurring revenues for the years ended December 31, 2018, 2017 and 2016. Our 50 largest customers accounted for approximately 38%, 37% and 36%, respectively, of our recurring revenues for the years ended December 31, 2018, 2017 and 2016.
Our non-recurring revenues are primarily comprised of installation services related to a customer's initial deployment and professional services we perform. These services are considered to be non-recurring because they are billed typically once, upon completion of the installation or the professional services work performed. The majority of these non-recurring revenues are typically billed on the first invoice distributed to the customer in connection with their initial installation. However, revenues from installation services are deferred and recognized ratably over the period of contract term. Additionally, revenue from contract settlements, when a customer wishes to terminate their contract early, is generally treated as a contract modification and recognized ratably over the remaining term of the contract, if any. As a percentage of total revenues, we expect non-recurring revenues to represent less than 10% of total revenues for the foreseeable future.
The largest components of our cost of revenues are depreciation, rental payments related to our leased IBX data centers, utility costs, including electricity, bandwidth access, IBX data center employees' salaries and benefits, including stock-based compensation, repairs and maintenance, supplies and equipment and security services. A majority of our cost of revenues is fixed in nature and should not vary significantly from period to period, unless we expand our existing IBX data centers or open or acquire new IBX data centers. However, there are certain costs that are considered more variable in nature, including utilities and supplies that are directly related to growth in our existing and new customer base. We expect the cost of our utilities, specifically electricity, will generally increase in the future on a per-unit or fixed basis, in addition to the variable increase related to the growth in consumption by our customers. In addition, the cost of electricity is generally higher in the summer months, as compared to other times of the year. To the extent we incur increased utility costs, such increased costs could materially impact our financial condition, results of operations and cash flows. Furthermore, to the extent we incur increased electricity costs as a result of either climate change policies or the physical effects of climate change, such increased costs could materially impact our financial condition, results of operations and cash flows. 
Sales and marketing expenses consist primarily of compensation and related costs for sales and marketing personnel, including stock-based compensation, amortization of contract costs, marketing programs, public relations, promotional materials and travel, as well as bad debt expense and amortization of customer relationship intangible assets.
General and administrative expenses consist primarily of salaries and related expenses, including stock-based compensation, accounting, legal and other professional service fees, and other general corporate expenses, such as our corporate regional headquarters office leases and some depreciation expense.
We expect our cost of revenues, sales and marketing expenses and general and administrative expenses to grow in absolute dollars in connection with our business growth. We may periodically see a higher cost of revenues as a percentage of revenue when a large expansion project opens or is acquired, before it starts generating any meaningful revenue. Furthermore, in relation to cost of revenues, the Americas region has a lower cost of revenues as a percentage of revenue than either EMEA or Asia-Pacific. This is due to both the increased scale and maturity of the Americas region, compared to either the EMEA or Asia-Pacific region, as well as a higher cost structure outside of the Americas, particularly in EMEA. We expect the trend that the Americas having the lowest cost of revenues as a percentage of revenues to continue. As a result, to the extent that revenue growth outside the Americas grows in greater proportion than revenue growth in the Americas, our overall cost of revenues as a percentage of revenues may increase in future periods. Sales and marketing expenses may periodically increase as a percentage of revenues as we continue to scale our operations by investing in sales and marketing initiatives to further increase our revenue, including the hiring of additional headcount and new product innovations. General and administrative expenses may also periodically increase as a percentage of revenues as we continue to grow our business.
Taxation as a REIT
We elected to be taxed as a REIT for federal income tax purposes beginning with our 2015 taxable year. As of December 31, 2018, our REIT structure included all of our data center operations in the U.S., Canada, Japan, and the data center operations in EMEA with the exception of Bulgaria, United Arab Emirates and a portion of Turkey. Our data center operations in other jurisdictions are operated as TRSs.

As a REIT, we generally are permitted to deduct from our federal taxable income the dividends we pay to our stockholders (including, for this purpose, the value of any deemed distributions attributable to anti-dilution adjustments made with respect to our 4.75% convertible subordinated notes prior to their maturity in 2016). The income represented by such dividends is not subject to federal income tax at the entity level but is taxed, if at all, at the stockholder level. Nevertheless, the income of our TRSs which hold our U.S. operations that may not be REIT compliant is subject, as applicable, to federal and state corporate income tax. Likewise, our foreign subsidiaries continue to be subject to foreign income taxes in jurisdictions in which they hold assets or conduct operations, regardless of whether held or conducted through TRSs or through QRSs. We are also subject to a separate corporate income tax on any 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, 2015, or (ii) an asset held by us or a QRS following the liquidation or other conversion of a former TRS). This built-in-gains 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, 2015 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. If we fail to remain qualified for federal income tax as a REIT, we will be subject to federal income tax at regular corporate tax rates. Even if we remain qualified for federal income tax 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 TRSs' 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 may not follow them at all.
On each of March 21, June 20, September 19, and December 12, 2018, we paid quarterly cash dividends of $2.28 per share. We expect these quarterly and other applicable distributions to equal or exceed the REIT taxable income that we recognized in 2018.
On December 22, 2017, the United States enacted legislation commonly referred to as the Tax Cuts and Jobs Act ("TCJA") which amended U.S. federal income tax laws. The TCJA retained the REIT regime but contained many significant changes that impact a REIT's taxable income subject to distribution, particularly a REIT with global operations. As of the end of 2018, we have finalized the analysis of the major tax impact to our business by the new tax legislation. Based on our current assessment, which is subject to further interpretation and guidance on the new tax legislation, we believe that we can continue to meet all the REIT compliance requirements in the foreseeable future and that the TCJA changes are not expected to meaningfully increase our tax liabilities in the U.S. because we expect to fully distribute our REIT taxable income.
We continue to monitor our REIT compliance in order to maintain our qualification for federal income tax as a REIT. For this and other reasons, as necessary, we may convert some of our data center operations in other countries into the REIT structure in future periods.
Results of Operations
Our results of operations for the year ended December 31, 2018 include the results of operations from the Metronode Acquisition from April 18, 2018 and the Infomart Dallas Acquisition from April 2, 2018. Our results of operations for the year ended December 31, 2017 include the results of operations of the IO Acquisition from February 3, 2017, the Verizon Data Center Acquisition from May 1, 2017, the Zenium data center acquisition from October 6, 2017 and the Itconic Acquisition from October 9, 2017. Our results of operations for the year ended December 31, 2016 include the results of operations of TelecityGroup from January 15, 2016 and the Paris IBX Data Center Acquisition from August 1, 2016.
In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers ("ASU 2014-09") and issued subsequent amendments to the initial guidance, collectively referred as "Topic 606." On January 1, 2018, as more fully described in Note 1 of the Notes to Consolidated Financial Statements in Item 8 of this Annual Report on Form 10-K, we adopted Topic 606. Results for reporting periods beginning after January 1, 2018 are presented under Topic 606, while the comparative information has not been restated and continues to be reported under accounting standards in effect for those periods. Under the new standard, we recognize installation revenue over the contract period rather than over the estimated installation life as under the prior revenue standard. We also capitalize and amortize certain costs to obtain contracts, rather than expense them immediately as under the previous standard.
Discontinued Operations
We present the results of operations associated with the TelecityGroup data centers that were divested in July 2016 as discontinued operations in our consolidated statement of operations for the year ended December 31, 2016. We did not have any discontinued operations activity during 2018 or 2017.

Americas Revenues. Revenues for our Americas region for the year ended December 31, 2018 included approximately $210.2 million of incremental revenues from the Verizon Data Center Acquisition, which closed in May 2017, and the Infomart Dallas Acquisition, which closed in April 2018. During both the years ended December 31, 2018 and 2017, our revenues from the United States, the largest revenue contributor in the Americas region for the periods, represented approximately 91% of the regional revenues. Excluding incremental revenues attributable to the Infomart Dallas and Verizon Data Center Acquisitions, growth in Americas revenues was primarily due to (i) $69.3 million of revenues generated from our recently-opened IBX data centers or IBX data center expansions in the Chicago, Culpeper, Denver, Houston, Miami, Rio de Janeiro, São Paulo, Seattle, Silicon Valley, and Washington, D.C. areas and (ii) an increase in orders from both our existing customers and new customers during the period. During the year ended December 31, 2018, the U.S. dollar was generally stronger relative to the Brazilian real than during the year ended December 31, 2017, resulting in approximately $23.6 million of unfavorable foreign currency impact on our Americas revenues during the year ended December 31, 2018 when compared to 2017 using average exchange rates.
EMEA Revenues.  Revenues for our EMEA region for the year ended December 31, 2018 included approximately $52.6 million of incremental revenues from the IO Acquisition, which closed in February 2017, and the Itconic and Zenium data center acquisitions, which closed in October 2017. Our revenues from the U.K., our largest revenue contributor in the EMEA region, represented 30% of regional revenues for both the years ended December 31, 2018 and 2017. Excluding incremental revenues attributable to the IO, Itconic, and Zenium acquisitions, our EMEA revenue growth was primarily due to (i) approximately $73.2 million of revenues from our recently-opened IBX data centers or IBX data center expansions in the Amsterdam, Frankfurt, London and Paris metro areas and (ii) an increase in orders from both our existing customers and new customers during the period. During the year ended December 31, 2018, the impact of foreign currency fluctuations resulted in approximately $54.4 million of net favorable foreign currency impact to our EMEA revenues primarily due to a generally weaker U.S. dollar relative to the Euro and British pound during the year ended December 31, 2018 compared to the year ended December 31, 2017.
Asia-Pacific Revenues.  Revenues for our Asia-Pacific region for the year ended December 31, 2018 included approximately $48.0 million of incremental revenues from the Metronode Acquisition, which closed in April 2018. Our revenues from Japan and Singapore, the largest revenue contributors in the Asia-Pacific region for the period, combined represented approximately 60% and 63% for the years ended December 31, 2018 and 2017, respectively. Excluding incremental revenues attributable to the Metronode Acquisition, our Asia-Pacific revenue growth was primarily due to (i) approximately $59.2 million of revenues generated from our recently-opened IBX data center expansions in the Hong Kong, Melbourne, Osaka, and Singapore metro areas and (ii) an increase in orders from both our existing customers and new customers during the period. During the year ended December 31,

2018, the U.S. dollar was generally weaker relative to the Singapore dollar and Japanese yen than during the year ended December 31, 2017, resulting in approximately $7.7 million of net favorable foreign currency impact to our Asia-Pacific revenues during the year ended December 31, 2018 when compared to 2017 using average exchange rates.

Americas Cost of Revenues. Cost of revenues for our Americas region for the year ended December 31, 2018 included approximately $115.4 million of incremental cost of revenues from the Verizon Data Center Acquisition and the Infomart Dallas Acquisition. Excluding the impact from these acquisitions, the increase in our Americas cost of revenues for the year ended December 31, 2018 compared to the year ended December 31, 2017 was primarily due to (i) $10.6 million higher depreciation expense primarily due to our IBX data center expansion activity; (ii) $7.6 million of higher taxes, licenses, insurance, and other cost of sales in support of our business growth; (iii) $5.8 million of higher rent and facility costs due to new fuel cell leases and IBX growth  and (iv) $15.5 million of higher compensation costs, including general salaries, bonuses and stock-based compensation and higher headcount growth (1,399 Americas cost of revenues employees as of December 31, 2018 versus 1,339 as of December 31, 2017). During the year ended December 31, 2018, the impact of foreign currency fluctuations resulted in approximately $15.1 million of net favorable foreign currency impact to our Americas cost of revenues primarily due to a generally stronger U.S. dollar relative to the Brazilian real during the year ended December 31, 2018 compared to the year ended December 31, 2017. We expect our Americas cost of revenues to increase as we continue to grow our business, including results from recent acquisitions.
EMEA Cost of Revenues. Cost of revenues for our EMEA region for the year ended December 31, 2018 included $41.5 million of incremental cost of revenues from the IO, Itconic, and Zenium acquisitions. Excluding incremental cost of revenues attributable to these acquisitions, the increase in our EMEA cost of revenues was primarily due to (i) $47.3 million of higher utilities costs driven by IBX expansions, increased usage and price increases; (ii) $18.4 million of higher office expenses, rent and facility costs, and repair and maintenance primarily due to an increase in expansion activity and usage due to our business growth; (iii) $49.3 million of higher depreciation and accretion expenses, primarily driven by expansion activity in Amsterdam, Frankfurt, London, and Paris and (iv) $19.7 million of higher compensation costs, including general salaries, bonuses and stock-based compensation and higher headcount growth (1,490 EMEA cost of revenues employees as of December 31, 2018 versus 1,375 as of December 31, 2017), partially offset by an $11.8 million reduction in other cost of sales, primarily due to realized cash flow hedge gains. During the year ended December 31, 2018, the impact of foreign currency fluctuations resulted in approximately $30.0 million of net unfavorable foreign currency impact to our EMEA cost of revenues, primarily due to a generally weaker U.S. dollar relative to the Euro and British pound during the year ended December 31, 2018 compared to the year ended December 31, 2017. We expect EMEA cost of revenues to increase as we continue to grow our business.
Asia-Pacific Cost of Revenues. Cost of revenues for our Asia-Pacific region for the year ended December 31, 2018 included approximately $33.2 million incremental cost of revenues from the Metronode Acquisition. Excluding the impact from the Metronode Acquisition, the increase in our Asia-Pacific cost of revenues for the year ended December 31, 2018 was primarily due to (i) $28.4 million of higher utilities costs, rent and facility costs and repairs and maintenance expense, primarily driven by higher usage in Australia, Hong Kong, Japan and Singapore; (ii) $16.1 million of higher depreciation and accretion expense, primarily from IBX expansions in Australia, Hong Kong, Japan and Singapore; (iii) $9.7 million of higher other cost of sales, primarily due

to custom service orders, and (iv) $3.9 million of higher compensation costs, including general salaries, bonuses and stock-based compensation and headcount growth (884 Asia-Pacific cost of revenues employees as of December 31, 2018 versus 828 as of December 31, 2017). During the year ended December 31, 2018, the U.S. dollar was generally weaker relative to the Singapore dollar and Japanese yen than during the year ended December 31, 2017, resulting in approximately $3.3 million of net unfavorable foreign currency impact to our Asia-Pacific cost of revenues in 2018. We expect Asia-Pacific cost of revenues to increase as we continue to grow our business, including the impact from the Metronode acquisition.
Sales and Marketing Expenses. Our sales and marketing expenses for the years ended December 31, 2018 and 2017 were split among the following geographic regions (dollars in thousands):

Americas Sales and Marketing Expenses. The increase in our Americas sales and marketing expenses was primarily due to (i) $38.1 million of amortization of the acquired intangible assets in connection with the Verizon Data Center Acquisition and (ii) $5.4 million of higher consulting expenses to support our growth. During the year ended December 31, 2018, the impact of foreign currency fluctuations to our Americas sales and marketing expenses was not significant when compared to average exchange rates during the year ended December 31, 2017. We anticipate that we will continue to invest in Americas sales and marketing initiatives and expect our Americas sales and marketing expenses to continue to increase as we continue to grow our business, including the impact from recent acquisitions.
EMEA Sales and Marketing Expenses. Our EMEA sales and marketing expense did not materially change during the year ended December 31, 2018 as compared to the year ended December 31, 2017. During the year ended December 31, 2018, the impact of foreign currency fluctuations resulted in approximately $4.8 million of net unfavorable foreign currency impact to our EMEA sales and marketing expenses primarily due to a generally weaker U.S. dollar relative to the Euro and British pound during the year ended December 31, 2018 compared to the year ended December 31, 2017. Over the past several years, we have been investing in our EMEA sales and marketing initiatives to further increase our revenues. We expect our EMEA sales and marketing expenses to continue to increase as we continue to grow our business.
Asia-Pacific Sales and Marketing Expenses. The increase in our Asia-Pacific sales and marketing expense is primarily due to (i) $4.1 million of amortization of the acquired intangible assets in connection with the Metronode Acquisition; (ii) $4.1 million of higher compensation costs, including sales compensation, general salaries, bonuses and stock-based compensation and headcount growth (306 Asia-Pacific sales and marketing employees as of December 31, 2018, versus 278 as of December 31, 2017) and (iii) $4.4 million of higher bad debt expense, primarily due to customer recovery in the prior year. For the year ended December 31, 2018, the impact of foreign currency fluctuations to our Asia-Pacific sales and marketing expenses was not significant when compared to average exchange rates for the year ended December 31, 2017. Over the past several years, we have been investing in our Asia-Pacific sales and marketing initiatives and expect our Asia-Pacific sales and marketing expenses to continue to increase as we continue to grow our business, including the impact from the Metronode acquisition.

General and Administrative Expenses. Our general and administrative expenses for the years ended December 31, 2018 and 2017 were split among the following geographic regions (dollars in thousands):

Americas General and Administrative Expenses. The increase in our Americas general and administrative expenses was primarily due to (i) $25.8 million of higher compensation costs, including general salaries, bonuses, stock-based compensation, and headcount growth (1,389 Americas general and administrative employees as of December 31, 2018 versus 1,207 as of December 31, 2017); (ii) $18.1 million of higher office, rent and facilities costs and consulting expenses in support of our business growth; (iii) $3.8 million of higher recruiting, training, and travel expenses to support employee development and (iv) $30.2 million of higher depreciation expense associated with the implementation of certain systems, including revenue, data management and cloud exchange systems, to improve our quote to order and billing processes and to support the integration and growth of our business. During the year ended December 31, 2018, the impact of foreign currency fluctuations to our Americas general and administrative expenses was not significant when compared to average exchange rates for the year ended December 31, 2017. Over the course of the past year, we have been investing in our Americas general and administrative functions to scale our business effectively for growth, which has included additional investments in improving our back office systems. We expect our current efforts to improve our back office systems will continue over the next several years. Going forward, although we are carefully monitoring our spending, we expect Americas general and administrative expenses to increase as we continue to further scale our operations to support our growth, including these investments in our back office systems, investments to maintain our qualification for taxation as a REIT and recent acquisitions and to comply with new accounting standards.
EMEA General and Administrative Expenses. The decrease in our EMEA general and administrative expenses was primarily due to (i) $23.1 million of lower amortization expense as a result of fully amortizing the TelecityGroup trade names during the third quarter of 2017; (ii) $5.2 million decrease due to realized cash flow hedge gains and (iii) $5.1 million lower outside services consulting expense, partially offset by an increase of $19.6 million of compensation expenses, including general salaries, bonuses, and stock-based compensation and headcount growth (830 EMEA general and administrative employees as of December 31, 2018 versus 807 as of December 31, 2017). During the year ended December 31, 2018, the impact of foreign currency fluctuations resulted in approximately $5.2 million of net unfavorable foreign currency impact to our EMEA general and administrative expenses primarily due to a generally weaker U.S. dollar relative to the Euro and British pound during the year ended December 31, 2018 compared to the year ended December 31, 2017. Over the course of the past year, we have been investing in our EMEA general and administrative functions as a result of our ongoing efforts to scale this region effectively for growth. Going forward, although we are carefully monitoring our spending, we expect our EMEA general and administrative expenses to increase in future periods as we continue to scale our operations to support our growth.
Asia-Pacific General and Administrative Expenses. The increase in our Asia-Pacific general and administrative expense was primarily due to $9.7 million of higher compensation costs, including general salaries, bonuses, stock-based compensation and headcount growth (482 Asia-Pacific general and administrative employees as of December 31, 2018 versus 453 as of December 31, 2017). For the year ended December 31, 2018, the impact of foreign currency fluctuations on our Asia-Pacific general and administrative expenses was not significant when compared to average exchange rates for the year ended December 31, 2017. Going forward, although we are carefully monitoring our spending, we expect Asia-Pacific general and administrative expenses to increase as we continue to support our growth, including the impact from the Metronode acquisition.

Acquisition Costs.  During the year ended December 31, 2018, we recorded acquisition costs totaling $34.4 million primarily in the Asia-Pacific and Americas regions, due to our acquisitions of Metronode and Infomart Dallas. During the year ended December 31, 2017, we recorded acquisition costs totaling $38.6 million, primarily in the Americas region, due to the Verizon Data Center Acquisition.
Impairment Charges. We did not have impairment charges during the years ended December 31, 2018 and 2017.
Gain on Asset Sales. During the year ended December 31, 2018, we recorded a gain on asset sales of $6.0 million primarily relating to the sale of a data center in Frankfurt. We did not have any gain on asset sales during the year ended December 31, 2017.
Income from Operations. Our income from operations for the years ended December 31, 2018 and 2017 was split among the following geographic regions (dollars in thousands):

Americas Income from Continuing Operations. The increase in our Americas income from operations was primarily due to higher income generated from acquisitions, higher revenues as a result of our IBX data center expansion activity and organic growth as described above. During the year ended December 31, 2018, the U.S. dollar was generally stronger relative to the Brazilian real than during the year ended December 31, 2017, resulting in approximately $4.0 million of unfavorable foreign currency impact on our Americas income from continuing operations during the year ended December 31, 2018 when compared to 2017 using average exchange rates.
EMEA Income from Continuing Operations. The increase in our EMEA income from operations was primarily due to higher revenues as a result of our IBX data center expansion activity and acquisitions, as described above, as well as lower sales and marketing and general and administrative expenses as a percentage of revenues, which was partially due to lower amortization costs as a result of fully amortizing the TelecityGroup trade names during the third quarter of 2017. During the year ended December 31, 2018, the impact of foreign currency fluctuations resulted in approximately $14.5 million of net favorable foreign currency impact to our EMEA income from continuing operations primarily due to a generally weaker U.S. dollar relative to the Euro and British pound during the year ended December 31, 2018 compared to the year ended December 31, 2017.
Asia-Pacific Income from Continuing Operations. The increase in our Asia-Pacific income from operations was primarily due to higher income generated from the Metronode Acquisition, higher revenues as a result of our IBX data center expansion activity and organic growth as described above and lower cost of sales as a percentage of revenues. During the year ended December 31, 2018, the U.S. dollar was generally weaker relative to the Singapore dollar and Japanese yen than during the year ended December 31, 2017, resulting in approximately $3.2 million of favorable foreign currency impact on our Asia-Pacific income from continuing operations during the year ended December 31, 2018 when compared to 2017 using average exchange rates.
Interest Income. Interest income was $14.5 million and $13.1 million for the years ended December 31, 2018 and 2017, respectively. The average yield for the year ended December 31, 2018 was 1.24% versus 0.64% for the year ended December 31, 2017.
Interest Expense.  Interest expense increased to $521.5 million for the year ended December 31, 2018 from $478.7 million for the year ended December 31, 2017. The increase in interest expense was primarily attributable to our issuance of the €750.0 million 2.875% Euro Senior Notes due 2024 in March 2018 and $750 million 5.000% Infomart Senior Notes in April 2018. The increase was partially offset by lower weighted average interest rates during the year ended December 31, 2018 as compared to the year ended December 31, 2017. During the years ended December 31, 2018 and 2017, we capitalized $19.9 million and $22.6 million, respectively, of interest expense to construction in progress. We expect to incur higher interest expense in future periods in connection with additional indebtedness that we incurred during 2018 and as a result of the increasing interest rates.
Other Income (Expense). We recorded net other income of $14.0 million and $9.2 million for the years ended December 31, 2018 and 2017, respectively, primarily due to foreign currency exchange gains and losses during the periods.
Loss on Debt Extinguishment. We recorded $51.4 million net loss on debt extinguishment during the year ended December 31, 2018, comprised of (i) $17.1 million of loss on debt extinguishment as a result of amendments to leases impacting the related

financing obligations; (ii) $19.5 million of loss on debt extinguishment from the settlement of financing obligations as a result of the Infomart Dallas Acquisition; (iii) $12.6 million of loss on debt extinguishment as a result of the settlement of financing obligations for properties purchased and (iv) $2.2 million of loss on debt extinguishment as a result of the redemption of the Japanese Yen Term Loan. During the year ended December 31, 2017, we recorded $65.8 million net loss on debt extinguishment comprised of (i) $14.6 million of loss on debt extinguishment from the early redemption of the senior notes; (ii) $22.5 million of loss on debt extinguishment from the redemption of term loans under the previously outstanding credit facility; (iii) $16.7 million of loss on debt extinguishment as a result of amendments to leases and financing obligations and (iv) $12.0 million of loss on debt extinguishment from the settlement of financing obligations as a result of properties purchased.
Income Taxes. We operate as a REIT for federal income tax purposes. As a REIT, we are generally not subject to federal income taxes on our taxable income distributed to stockholders. We intend to distribute or have distributed the entire taxable income generated by the operations of our QRSs for the years ended December 31, 2018 and December 31, 2017, respectively. As such, other than tax attributable to built-in-gains recognized and withholding taxes, no provision for U.S. income taxes for the QRSs has been included in the accompanying consolidated financial statements for the years ended December 31, 2018 and 2017.
We have made TRS elections for some of our subsidiaries in and outside the U.S. In general, a TRS may provide services that would otherwise be considered impermissible for REITs to provide and may hold assets that REITs cannot hold directly. U.S. income taxes for the TRS entities located in the U.S. and foreign income taxes for our foreign operations regardless of whether the foreign operations are operated as QRSs or TRSs have been accrued, as necessary, for the years ended December 31, 2018 and 2017.
For the years ended December 31, 2018 and 2017, we recorded $67.7 million and $53.9 million of income tax expenses, respectively. Our effective tax rates were 15.6% and 18.8%, respectively, for the years ended December 31, 2018 and 2017. The decrease in the effective tax rate in 2018 as compared to 2017 is primarily due to a release of valuation allowance in the current period as a result of a legal entity reorganization in our Americas region.
Adjusted EBITDA. Adjusted EBITDA is a key factor in how we assess the operating performance of our segments and develop regional growth strategies such as IBX data center expansion decisions. We define adjusted EBITDA as income or loss from operations plus depreciation, amortization, accretion, stock-based compensation expense, restructuring charges, impairment charges, acquisition costs and gain on asset sales. See "Non-GAAP Financial Measures" below for more information about adjusted EBITDA and a reconciliation of adjusted EBITDA to income or loss from operations. Our adjusted EBITDA for the years ended December 31, 2018 and 2017 was split among the following geographic regions (dollars in thousands):

Americas Adjusted EBITDA. The increase in our Americas adjusted EBITDA was primarily due to the Verizon Data Center Acquisition and the Infomart Dallas Acquisition, higher revenues as a result of our IBX data center expansion activity and organic growth as described above. During the year ended December 31, 2018, currency fluctuations resulted in approximately $9.6 million of net unfavorable foreign currency impact on our Americas adjusted EBITDA primarily due to the U.S. dollar being generally stronger relative to the Brazilian real during the year ended December 31, 2018 compared to the year ended December 31, 2017.
EMEA Adjusted EBITDA. The increase in our EMEA adjusted EBITDA was primarily due to higher revenues as a result of our IBX data center expansion activity and acquisitions, as described above, as well as lower sales and marketing and general and administrative expenses as a percentage of revenues. During the year ended December 31, 2018, currency fluctuations resulted in approximately $26.6 million of net favorable foreign currency impact to our EMEA adjusted EBITDA primarily due to a generally weaker U.S. dollar relative to the Euro and British pound during the year ended December 31, 2018 compared to the year ended December 31, 2017.
Asia-Pacific Adjusted EBITDA. The increase in our Asia-Pacific adjusted EBITDA was primarily due to the Metronode Acquisition, higher revenues as a result of our IBX data center expansion activity and organic growth as described above and lower cost of revenues as a percentage of revenues. During the year ended December 31, 2018, the U.S. dollar was generally weaker relative to the Singapore dollar and Japanese yen than during the year ended December 31, 2017, resulting in approximately

$4.4 million of net favorable foreign currency impact to our Asia-Pacific revenues during the year ended December 31, 2018 when compared to average exchange rates during the year ended December 31, 2017.

Americas Revenues. Revenues for our Americas region for the year ended December 31, 2017 included approximately $359.1 million of revenues attributable to the Verizon Data Center Acquisition. During the years ended December 31, 2017 and 2016, our revenues from the United States, the largest revenue contributor in the Americas region for the periods, represented approximately 91% and 92%, respectively, of the regional revenues. Excluding revenues attributable to the Verizon Data Center Acquisition, growth in Americas revenues was primarily due to (i) $34.5 million of revenue generated from our recently-opened IBX data centers or IBX data center expansions in the Dallas, New York, São Paulo, Silicon Valley, Toronto and Washington, D.C. areas and (ii) an increase in orders from both our existing customers and new customers during the period. During the year ended December 31, 2017, the U.S. dollar was generally weaker relative to the Canadian dollar and Brazilian real than during the year ended December 31, 2016, resulting in approximately $11.4 million of favorable foreign currency impact on our Americas revenues during the year ended December 31, 2017 when compared to 2016 using average exchange rates.
EMEA Revenues.  As compared to 2016, revenues for our EMEA region for the year ended December 31, 2017 include $47.2 million of incremental revenues from acquisitions including the TelecityGroup Acquisition, which closed on January 15, 2016, the Paris IBX Data Center Acquisition, which closed in August 2016, the IO Acquisition, which closed in February 2017, and the Itconic and Zenium data center acquisitions, which closed in October 2017. Our revenues from the U.K., our largest revenue contributor in the EMEA region, represented 30% of regional revenues for the year ended December 31, 2017 compared to 32% of regional revenues for the year ended December 31, 2016. Excluding the acquisitions, our EMEA revenue growth was primarily due to (i) approximately $62.3 million of revenue from our IBX data centers or IBX data center expansions in the Amsterdam, Dubai, Dublin, Frankfurt, Helsinki, London, Paris and Zurich metro areas and (ii) an increase in orders from both our existing customers and new customers during the period. During the year ended December 31, 2017, the impact of foreign currency fluctuations resulted in approximately $4.9 million of net unfavorable foreign currency impact to our EMEA revenues primarily due to a generally stronger U.S. dollar relative to the British pound during the year ended December 31, 2017 compared to the year ended December 31, 2016.
Asia-Pacific Revenues.  Our revenues from Japan, the largest revenue contributor in the Asia-Pacific region, represented approximately 34% and 35%, respectively, for the year ended December 31, 2017 and 2016. Our Asia-Pacific revenue growth was primarily due to (i) approximately $42.6 million of revenue generated from our recently-opened IBX data center expansions in

the Hong Kong, Osaka and Sydney metro areas and (ii) an increase in orders from both our existing customers and new customers during the period. During the year ended December 31, 2017, the U.S. dollar was generally stronger relative to the Japanese Yen than during the year ended December 31, 2016, resulting in approximately $6.8 million of net unfavorable foreign currency impact to our Asia-Pacific revenues during the year ended December 31, 2017 when compared to 2016 using average exchange rates.

Americas Cost of Revenues. Cost of revenues for our Americas region for the year ended December 31, 2017 included approximately $177.4 million of costs of revenues attributable to the Verizon Data Center Acquisition. Excluding the impact from the Verizon Data Center Acquisition, depreciation expense was $273.0 million and $241.6 million, respectively, for the years ended December 31, 2017 and 2016. The growth in depreciation expense was primarily due to our IBX expansion activity. In addition to the increase in depreciation expense, the increase in our Americas cost of revenues for the year ended December 31, 2017 compared to the year ended December 31, 2016 was primarily due to (i) $30.4 million of higher utilities, repairs and maintenance, property taxes, and other cost of sales in support of our business growth and (ii) $13.2 million of higher compensation costs, including general salaries, bonuses and stock-based compensation (1,114 Americas cost of revenues employees, excluding the Verizon Data Center Acquisition, as of December 31, 2017 versus 1,023 as of December 31, 2016). During the year ended December 31, 2017, the impact of foreign currency fluctuations resulted in approximately $7.7 million of net unfavorable foreign currency impact to our Americas cost of revenues primarily due to a generally weaker U.S. dollar relative to the Brazilian real and Canadian dollar during the year ended December 31, 2017 compared to the year ended December 31, 2016.
EMEA Cost of Revenues. As compared to 2016, cost of revenues for our EMEA region for the year ended December 31, 2017 included $36.7 million of incremental cost of revenues attributable to acquisitions, including the TelecityGroup Acquisition that closed on January 15, 2016, the Paris IBX Data Center Acquisition that closed in August 2016, the IO Acquisition, which closed in February 2017, and the Itconic and Zenium data center acquisitions, which closed in October 2017. Excluding cost of revenues attributable to these acquisitions, the increase in our EMEA cost of revenues was primarily due to (i) $25.5 million of higher utilities in support of our business growth; (ii) $16.4 million of higher other cost of sales, including third party and managed service expenses; (iii) $10.7 million of higher depreciation expense and (iv) $7.2 million of higher compensation costs, including general salaries, bonuses and stock-based compensation (743 EMEA cost of revenues employees, excluding TelecityGroup employees, as of December 31, 2017 versus 623 as of December 31, 2016). During the year ended December 31, 2017, the impact of foreign currency fluctuations resulted in approximately $2.7 million of net favorable foreign currency impact to our EMEA cost of revenues, primarily due to a generally stronger U.S. dollar relative to the British pound during the year ended December 31, 2017 compared to the year ended December 31, 2016.
Asia-Pacific Cost of Revenues. The increase in our Asia-Pacific cost of revenues was primarily due to (i) $16.7 million of higher utilities, rent, facility costs, consulting, bandwidth cost, custom service orders and repairs and maintenance costs in support of our business growth and (ii) $3.3 million of higher compensation costs, including general salaries, bonuses and stock-based compensation and headcount growth (828 Asia-Pacific cost of revenues employees as of December 31, 2017 versus 787 as of December 31, 2016), partially offset by a decrease of $3.2 million in depreciation and accretion expenses. During the year ended

December 31, 2017, the U.S. dollar was generally stronger relative to the Japanese Yen than during the year ended December 31, 2016, resulting in approximately $5.0 million of net favorable foreign currency impact to our Asia-Pacific cost of revenues in 2017.
Sales and Marketing Expenses. Our sales and marketing expenses for the years ended December 31, 2017 and 2016 were split among the following geographic regions (dollars in thousands):

Americas Sales and Marketing Expenses. The increase in our Americas sales and marketing expenses was primarily due to (i) $75.3 million of amortization of the acquired intangible assets in connection with the Verizon Data Center Acquisition; (ii) $33.1 million of higher compensation costs, including sales compensation, general salaries, bonuses and stock-based compensation and headcount growth (608 Americas sales and marketing employees, including those from the Verizon Data Center Acquisition, as December 31, 2017, versus 553 as of December 31, 2016) and (iii) $4.1 million of higher consulting expenses to support our growth. During the year ended December 31, 2017, the impact of foreign currency fluctuations to our Americas sales and marketing expenses was not significant when compared to average exchange rates during the year ended December 31, 2016.
EMEA Sales and Marketing Expenses. The increase in the EMEA sales and marketing expense was primarily due to (i) $12.3 million of higher compensation costs, including sales compensation, general salaries, bonuses, stock-based compensation and headcount growth (378 EMEA sales and marketing employees as of December 31, 2017 versus 349 as of December 31, 2016) and (ii) an increase of $1.8 million in depreciation and amortization expense, primarily due to acquisitions made during the current year. During the year ended December 31, 2017, the impact of foreign currency fluctuations resulted in approximately $2.8 million of net favorable foreign currency impact to our EMEA sales and marketing expenses primarily due to a generally stronger U.S. dollar relative to the British pound during the year ended December 31, 2017 compared to the year ended December 31, 2016.
Asia-Pacific Sales and Marketing Expenses. The increase in the Asia-Pacific sales and marketing expense is primarily due to (i) $6.5 million of higher compensation costs, including sales compensation, general salaries, bonuses, stock-based compensation and a larger average headcount in 2017 as compared to 2016 and (ii) $3.2 million of higher rent expense in support of our growth. For the year ended December 31, 2017, the impact of foreign currency fluctuations to our Asia-Pacific sales and marketing expenses was not significant when compared to average exchange rates for the year ended December 31, 2016.
General and Administrative Expenses. Our general and administrative expenses for the years ended December 31, 2017 and 2016 were split among the following geographic regions (dollars in thousands):

Americas General and Administrative Expenses. The increase in our Americas general and administrative expenses was primarily due to (i) $35.5 million of higher compensation costs, including general salaries, bonuses, stock-based compensation, and headcount growth (1,207 Americas general and administrative employees, including those from the Verizon Data Center Acquisition, as of December 31, 2017 versus 934 as of December 31, 2016); (ii) $22.9 million of higher depreciation expense associated with certain systems, including revenue, data management and cloud exchange systems, to improve our quote to order and billing processes and to support the integration and growth of our business and (iii) $16.6 million of higher office expense and consulting cost to support our growth. During the year ended December 31, 2017, the impact of foreign currency fluctuations to our Americas general and administrative expenses was not significant when compared to average exchange rates for the year ended December 31, 2016. Over the course of the past year, we have been investing in our Americas general and administrative functions to scale this region effectively for growth, which has included additional investments in improving our back office systems. We expect our current efforts to improve our back office systems will continue over the next several years. Going forward, although we are carefully monitoring our spending, we expect Americas general and administrative expenses to increase as we continue to further scale our operations to support our growth, including these investments in our back office systems and investments to maintain our qualification for taxation as a REIT.
EMEA General and Administrative Expenses. The decrease in our EMEA general and administrative expenses was primarily due to (i) $20.8 million of lower amortization expenses as a result of fully amortizing the TelecityGroup trade names during the current period and (ii) $8.4 million of lower consulting expenses which was largely due to the completion of TelecityGroup integration activities in the current period. During the year ended December 31, 2017, the impact of foreign currency fluctuations resulted in approximately $5.7 million of net favorable foreign currency impact to our EMEA general and administrative expenses primarily due to a generally stronger U.S. dollar relative to the British pound during the year ended December 31, 2017 compared to the year ended December 31, 2016. Over the course of the past year, we have been investing in our EMEA general and administrative functions as a result of our ongoing efforts to scale this region effectively for growth.
Asia-Pacific General and Administrative Expenses. The increase in our Asia-Pacific general and administrative expense was primarily due to $5.0 million of higher compensation costs, including general salaries, bonuses, stock-based compensation and headcount growth (453 Asia-Pacific general and administrative employees as of December 31, 2017 versus 358 as of December 31, 2016), partially offset by a $1.3 million decrease in rent, repair and maintenance expense. For the year ended December 31, 2017, the impact of foreign currency fluctuations on our Asia-Pacific general and administrative expenses was not significant when compared to average exchange rates for the year ended December 31, 2016.
Acquisition Costs.  During the year ended December 31, 2017, we recorded acquisition costs totaling $38.6 million primarily in the Americas and EMEA regions, of which $28.5 million was related to the Verizon Data Center Acquisition during the year ended December 31, 2017 attributable to the Americas region. During the year ended December 31, 2016, we recorded acquisition costs totaling $64.2 million primarily in the EMEA region due to the acquisitions of Telecity and the Paris IBX Data Center, and to a lesser degree, to the Americas region.
Impairment Charges. During the year ended December 31, 2016, we recorded impairment charges totaling $7.7 million in the Asia-Pacific region relating to assets held for sale. We did not have impairment charges during the year ended December 31, 2017.
Gain on Asset Sales. During the year ended December 31, 2016, we recorded a gain on asset sales of $32.8 million primarily relating to the sale of the LD2 data center in the EMEA region and a parcel of land in San Jose in the Americas region. We did not have any gain on asset sales during the year ended December 31, 2017.

Income from Operations. Our income from operations for the years ended December 31, 2017 and 2016 was split among the following geographic regions (dollars in thousands):

Americas Income from Continuing Operations. Our Americas income from continuing operations did not change significantly year over year. While revenues increased as described above, this was largely offset by (i) an increase of $18.6 million in acquisition costs, which was primarily related to the Verizon Data Center Acquisition; (ii) additional amortization of the acquired intangible assets resulted from the Verizon Data Center Acquisition and (iii) higher cost of revenues and sales and marketing expense as a percentage of revenues. The impact of foreign currency fluctuations on our Americas income from continuing operations for the year ended December 31, 2017 was not significant when compared to the year ended December 31, 2016.
EMEA Income from Continuing Operations. The increase in our EMEA income from continuing operations was primarily due to higher revenues as a result of our IBX data center expansion activity and acquisitions, as described above, as well as lower operating expenses as a percentage of revenues, lower amortization costs as a result of fully amortizing the TelecityGroup trade names during the current period and lower acquisition costs incurred for the year ended December 31, 2017. We incurred $9.2 million of acquisition costs during the year ended December 31, 2017, as compared to $54.5 million of acquisition costs during the year ended December 31, 2016, which was primarily related to our acquisition of TelecityGroup. During the year ended December 31, 2017, the impact of foreign currency fluctuations resulted in approximately $6.4 million of net favorable foreign currency impact to our EMEA income from continuing operations primarily due to a generally weaker U.S. dollar relative to the Euro during the year ended December 31, 2017 compared to the year ended December 31, 2016.
Asia-Pacific Income from Continuing Operations. The increase in our Asia-Pacific income from continuing operations was primarily due to higher revenues as result of our IBX data center expansion activity and organic growth as described above and lower cost of revenues as a percentage of revenues. The impact of foreign currency fluctuations on our Asia-Pacific income from continuing operations for the year ended December 31, 2017 was not significant when compared to average exchange rates of the year ended December 31, 2016.
Interest Income. Interest income was $13.1 million and $3.5 million for the years ended December 31, 2017 and 2016, respectively. The increase in interest income was driven by higher cash balances and interest yield rates for the year ended December 31, 2017. The average yield for the year ended December 31, 2017 was 0.64% versus 0.37% for the year ended December 31, 2016.
Interest Expense.  Interest expense increased to $478.7 million for the year ended December 31, 2017 from $392.2 million for the year ended December 31, 2016. The increase in interest expense was primarily due to the Term B-2 Loan borrowings of €1.0 billion and the issuance of $1.25 billion of 2027 Senior Notes in March 2017, as well as additional financings such as various capital lease and other financing obligations to support our expansion projects. During the years ended December 31, 2017 and 2016, we capitalized $22.6 million and $13.3 million, respectively, of interest expense to construction in progress.
Other Income (Expense). We recorded net other income of $9.2 million and net expense of $57.9 million for the years ended December 31, 2017 and 2016, respectively, primarily due to foreign currency exchange gains and losses during the periods, including $63.5 million in foreign currency losses recognized in the first quarter of 2016 as a result of completing the acquisition of TelecityGroup.
Loss on Debt Extinguishment. We recorded $65.8 million net loss on debt extinguishment during the year ended December 31, 2017 comprised of (i) $14.6 million of loss on debt extinguishment from the early redemption of the senior notes; (ii) $22.5 million of loss on debt extinguishment from the redemption of term loans under the previously outstanding credit facility; (iii) $16.7 million of loss on debt extinguishment as a result of amendments to leases and financing obligations and (iv) $12.0 million of loss on debt extinguishment from the settlement of financing obligations of properties purchased. During the year ended December 31, 2016, we recorded a $12.3 million loss on debt extinguishment as a result of the settlement of the financing obligations for our Paris 3 IBX data center, a portion of the lender fees associated with the Japanese Yen Term Loan, and the prepayment and termination of our 2012 and 2013 Brazil financings.

Income Taxes. We operate as a REIT for federal income tax purposes. As a REIT, we are generally not subject to federal income taxes on our taxable income distributed to stockholders. We intend to distribute or have distributed the entire taxable income generated by the operations of our REIT and QRSs for the years ended December 31, 2017 and December 31, 2016, respectively. As such, other than built-in-gains recognized and withholding taxes, no provision for U.S. income taxes for the REIT and QRSs has been included in the accompanying consolidated financial statements for the years ended December 31, 2017 and 2016.
We have made TRS elections for some of our subsidiaries in and outside the U.S. In general, a TRS may provide services that would otherwise be considered impermissible for REITs to provide and may hold assets that REITs cannot hold directly. U.S. income taxes for the TRS entities located in the U.S. and foreign income taxes for our foreign operations regardless of whether the foreign operations are operated as QRSs or TRSs have been accrued, as necessary, for the years ended December 31, 2017 and 2016.
For the years ended December 31, 2017 and 2016, we recorded $53.9 million and $45.5 million of income tax expenses, respectively. Our effective tax rates were 18.8% and 28.4%, respectively, for the years ended December 31, 2017 and 2016. The decrease in the effective tax rate in 2017 as compared to 2016 is primarily due to recognition of unrecognized tax benefits related to our tax positions in the U.S. and Brazil as a result of a lapse in statutes of limitations and lower amount of non-deductible expenses within our EMEA operations. This is partially offset by net deferred tax asset remeasurement in the U.S. TRSs due to the corporate income tax rate reduction from 35% to 21% effective January 1, 2018 as a result of the TCJA.
Adjusted EBITDA. Adjusted EBITDA is a key factor in how we assess the operating performance of our segments and develop regional growth strategies such as IBX data center expansion decisions. We define adjusted EBITDA as income or loss from operations plus depreciation, amortization, accretion, stock-based compensation expense, restructuring charges, impairment charges, acquisition costs and gain on asset sales. See "Non-GAAP Financial Measures" below for more information about adjusted EBITDA and a reconciliation of adjusted EBITDA to income or loss from operations. Our adjusted EBITDA for the years ended December 31, 2017 and 2016 was split among the following geographic regions (dollars in thousands):

Americas Adjusted EBITDA. The increase in our Americas adjusted EBITDA was primarily due to the Verizon Data Center Acquisition, higher revenues as result of our IBX data center expansion activity and organic growth as described above. During the year ended December 31, 2017, currency fluctuations resulted in approximately $4.5 million of net favorable foreign currency impact on our Americas adjusted EBITDA primarily due to the U.S. dollar being generally weaker relative to the Canadian dollar and Brazilian real during the year ended December 31, 2017 compared to the year ended December 31, 2016.
EMEA Adjusted EBITDA. The increase in our EMEA adjusted EBITDA was primarily due to higher revenues as a result of our IBX data center expansion activity and organic growth as described above and lower operating expenses as a percentage of revenues. During the year ended December 31, 2017, currency fluctuations resulted in approximately $2.1 million of net favorable foreign currency impact to our EMEA adjusted EBITDA primarily due to a generally weaker U.S. dollar relative to the Euro during the year ended December 31, 2017 compared to the year ended December 31, 2016.
Asia-Pacific Adjusted EBITDA. The increase in our Asia-Pacific adjusted EBITDA was primarily due to higher revenues as a result of our IBX data center expansion activity and organic growth, as described above, and lower cost of revenues as a percentage of revenues. During the year ended December 31, 2017, the U.S. dollar was generally stronger relative to the Japanese Yen than during the year ended December 31, 2016, resulting in approximately $2.7 million of net unfavorable foreign currency impact to our Asia-Pacific revenues during the year ended December 31, 2017 when compared to average exchange rates during the year ended December 31, 2016.
Non-GAAP Financial Measures
We provide all information required in accordance with GAAP, but we believe that evaluating our ongoing operating results may be difficult if limited to reviewing only GAAP financial measures. Accordingly, we use non-GAAP financial measures to evaluate our operations.

Non-GAAP financial measures are not a substitute for financial information prepared in accordance with GAAP. Non-GAAP financial measures should not be considered in isolation, but should be considered together with the most directly comparable GAAP financial measures and the reconciliation of the non-GAAP financial measures to the most directly comparable GAAP financial measures. We have presented such non-GAAP financial measures to provide investors with an additional tool to evaluate our operating results in a manner that focuses on what management believes to be our core, ongoing business operations. We believe that the inclusion of these non-GAAP financial measures provides consistency and comparability with past reports and provides a better understanding of the overall performance of the business and ability to perform in subsequent periods. We believe that if we did not provide such non-GAAP financial information, investors would not have all the necessary data to analyze Equinix effectively.
Investors should note that the non-GAAP financial measures used by us may not be the same non-GAAP financial measures, and may not be calculated in the same manner, as those of other companies. Investors should therefore exercise caution when comparing non-GAAP financial measures used by us to similarly titled non-GAAP financial measures of other companies.
Our primary non-GAAP financial measures, adjusted EBITDA and adjusted funds from operations ("AFFO"), exclude depreciation expense as these charges primarily relate to the initial construction costs of our IBX data centers and do not reflect our current or future cash spending levels to support our business. Our IBX data centers are long-lived assets and have an economic life greater than 10 years. The construction costs of an IBX data center do not recur with respect to such data center, although we may incur initial construction costs in future periods with respect to additional IBX data centers, and future capital expenditures remain minor relative to our initial investment. This is a trend we expect to continue. In addition, depreciation is also based on the estimated useful lives of our IBX data centers. These estimates could vary from actual performance of the asset, are based on historical costs incurred to build out our IBX data centers and are not indicative of current or expected future capital expenditures. Therefore, we exclude depreciation from our operating results when evaluating our operations.
In addition, in presenting adjusted EBITDA and AFFO, we exclude amortization expense related to acquired intangible assets. Amortization expense is significantly affected by the timing and magnitude of our acquisitions and these charges may vary in amount from period to period. We exclude amortization expense to facilitate a more meaningful evaluation of our current operating performance and comparisons to our prior periods. We exclude accretion expense, both as it relates to asset retirement obligations as well as accrued restructuring charge liabilities, as these expenses represent costs which we believe are not meaningful in evaluating our current operations. We exclude stock-based compensation expense, as it can vary significantly from period to period based on share price, the timing, size and nature of equity awards. As such, we, and many investors and analysts, exclude stock-based compensation expense to compare our operating results with those of other companies. We also exclude restructuring charges. The restructuring charges relate to our decisions to exit leases for excess space adjacent to several of our IBX data centers, which we did not intend to build out, or our decision to reverse such restructuring charges. We also exclude impairment charges related to certain long-lived assets. The impairment charges are related to expense recognized whenever events or changes in circumstances indicate that the carrying amount of long-lived assets are not recoverable. We also exclude gain or loss on asset sales as it represents profit or loss that is not meaningful in evaluating the current or future operating performance. Finally, we exclude acquisition costs from AFFO and adjusted EBITDA to allow more comparable comparisons of our financial results to our historical operations. The acquisition costs relate to costs we incur in connection with business combinations. Such charges generally are not relevant to assessing the long-term performance of the company. In addition, the frequency and amount of such charges vary significantly based on the size and timing of the acquisitions. Management believes items such as restructuring charges, impairment charges, gain or loss on asset sales and acquisition costs are non-core transactions; however, these types of costs may occur in future periods.

Our adjusted EBITDA results have improved each year and in each region in total dollars due to the improved operating results discussed earlier in "Results of Operations", as well as the nature of our business model consisting of a recurring revenue stream and a cost structure which has a large base that is fixed in nature also discussed earlier in "Overview".
Funds from Operations ("FFO") and AFFO
We use FFO and AFFO, which are non-GAAP financial measures commonly used in the REIT industry. FFO is calculated in accordance with the standards established by the National Association of Real Estate Investment Trusts. FFO represents net income (loss), excluding gain (loss) from the disposition of real estate assets, depreciation and amortization on real estate assets and adjustments for unconsolidated joint ventures' and non-controlling interests' share of these items.
In presenting AFFO, we exclude certain items that we believe are not good indicators of our current or future operating performance. AFFO represents FFO excluding depreciation and amortization expense on non-real estate assets, accretion, stock-based compensation, restructuring charges, impairment charges, acquisition costs, an installation revenue adjustment, a straight-line rent expense adjustment, a contract cost adjustment, amortization of deferred financing costs and debt discounts and premiums, gain (loss) on debt extinguishment, an income tax expense adjustment, recurring capital expenditures and adjustments for unconsolidated joint ventures' and noncontrolling interests' share of these items and net income (loss) from discontinued operations, net of tax. The adjustments for installation revenue, straight-line rent expense and contract costs are intended to isolate the cash activity included within the straight-lined or amortized results in the consolidated statement of operations. We exclude the amortization of deferred financing costs and debt discounts and premiums as these expenses relate to the initial costs incurred in connection with debt financings that have no current or future cash obligations. We exclude gain (loss) on debt extinguishment since it generally represents the write-off of initial costs incurred in connection with debt financings or a cost that is incurred to reduce future interest costs and is not a good indicator of our current or future operating performance. We include an income tax expense adjustment, which represents the non-cash tax impact due to changes in valuation allowances, uncertain tax positions and deferred taxes that do not relate to current period's operations. We deduct recurring capital expenditures, which represent expenditures to extend the useful life of its IBX data centers or other assets that are required to support current revenues. We also exclude net income (loss) from discontinued operations, net of tax, which represents results that may not recur and are not a good indicator of our current future operating performance.

Constant Currency Presentation
Our revenues and certain operating expenses (cost of revenues, sales and marketing and general and administrative expenses) from our international operations have represented and will continue to represent a significant portion of our total revenues and certain operating expenses. As a result, our revenues and certain operating expenses have been and will continue to be affected by changes in the U.S. dollar against major international currencies such as the Euro, British pound, Japanese yen, Singapore dollar, Australian dollar and Brazilian real. In order to provide a framework for assessing how each of our business segments performed excluding the impact of foreign currency fluctuations, we present period-over-period percentage changes in our revenues and certain operating expenses on a constant currency basis in addition to the historical amounts as reported. Presenting constant currency results of operations is a non-GAAP financial measure and is not meant to be considered in isolation or as an alternative to GAAP results of operations. However, we have presented this non-GAAP financial measure to provide investors with an additional tool to evaluate our operating results. To present this information, our current and comparative prior period revenues and certain operating expenses from entities reporting in currencies other than the U.S. dollar are converted into U.S. dollars at constant exchange rates rather than the actual exchange rates in effect during the respective periods (i.e. average rates in effect for the year ended December 31, 2017 are used as exchange rates for the year ended December 31, 2018 when comparing the year

ended December 31, 2018 with the year ended December 31, 2017, and average rates in effect for the year ended December 31, 2016 are used as exchange rates for the year ended December 31, 2017 when comparing the year ended December 31, 2017 with the year ended December 31, 2016).
Liquidity and Capital Resources
As of December 31, 2015,2018, our total indebtedness was comprised of (i) convertible debt principal totaling $150.1 million from our 4.75% convertible subordinated notes (gross of discount) and (ii) non-convertible debt and financing obligations totaling approximately $6.4$11.4 billion consisting of (a) approximately $3.9 billion$8,500.1 million of principal from our senior notes, (b) approximately $1.3 billion$1,518.9 million from our capital lease and other financing obligations (c) $325.6 million from our revolving credit facility, and (c) $920.1$1,390.4 million of principal from our mortgage and other loans payable and mortgage (gross of debt issuance cost, debt discount, andplus debt premium).
We believe we have sufficient cash, coupled with anticipated cash generated from operating activities, to meet our operating requirements, including repayment of the current portion of our debt as it becomes due, payment of regular dividend and special distributions due to our REIT conversion (see below) and completion of our publicly-announced expansion projects.
On March 14, 2018, we issued €750.0 million 2.875% Euro Senior Notes due 2024. On April 2, 2018, we completed the Infomart Dallas Acquisition for a purchase price of approximately $804.0 million, which was funded with approximately $45.8 million in cash and $758.2 million aggregate fair value of 5.000% senior unsecured notes. On April 18, 2018, we completed the Metronode Acquisition for a cash purchase price of A$1.034 billion or approximately $804.6 million at the exchange rate in effect on April 18, 2018. In July, we drew down the full amount of the JPY Term Loan of ¥47.5 billion, or approximately $424.7 million at the exchange rate effective on July 31, 2018, and prepaid the remaining principal of our existing Japanese Yen Term Loan of ¥43.8 billion or approximately $391.3 million. As of December 31, 2015,2018, we had $2.2 billion$610.7 million of cash, cash equivalents and short-term and long-term investments, of which approximately $2.0 billion$280.1 million was held in the U.S. In January 2016, we used £1.2 billion, or approximately $1.7 billion in U.S. dollars at exchange rates in effect on January 15, 2016, to fund the cash portion of the TelecityGroup purchase price. We believe that our current expansion activities in the U.S. can be funded with our U.S.-based cash and cash equivalents and investments. In addition to our cash and investment portfolio, we have additional liquidity available to us from our $2.0 billion revolving facility and the 2018 ATM Program as described below. 
As of December 31, 2015,2018, we had 3042 irrevocable letters of credit totaling $55.3$68.5 million issued and outstanding under the revolving credit facility; as a result of these letters of credit plus $325.6 million of outstanding borrowings under our revolving credit facility, wefacility. We had a total of approximately $1.1$1.9 billion of additional liquidity available to us under the revolving credit facility. Revolving Facility.
For the year ended December 31, 2018, we sold 930,934 shares for approximately $388.2 million, net of payment of commissions to the sales agents and equity offering costs under our 2017 ATM Program. As of December 31, 2018, no shares remain available for sale under the 2017 ATM Program. In December 2018, we launched the 2018 ATM Program to sell up to $750.0 million of common stock in at the market offerings. As of December 31, 2018, no shares have been sold under the 2018 ATM Program.
Besides any further financing activitiesactivity we may pursue, customer collections are our primary source of cash. While we believe we have a strong customer base, and have continued to experience relatively strong collections, if the current market conditions were to deteriorate, some of our customers may have difficulty paying us and we may experience increased churn in our customer base, including reductions in their commitments to us, all of which could have a material adverse effect on our liquidity. Additionally, we may pursue additional expansion opportunities, primarily the build out of new IBX data centers, in certain of our existing markets which are at or near capacity within the next year, as well as potential acquisitions. We are also now operating as a REIT (see below).acquisitions and joint ventures. While we expect to fund these plans with our existing resources, additional financing, either debt or equity, may be required, and if current market conditions were to deteriorate, we may be unable to secure additional financing, or any such additional financing may only be available to us on unfavorable terms. An inability to pursue additional expansion opportunities will have a material adverse effect on our ability to maintain our desired level of revenue growth in future periods.
Impact of REIT Conversion
We completed our conversion to a REIT in 2014 and began operating as a REIT effective January 1, 2015. As a result of our conversion to a REIT, we made special distributions to our stockholders in 2015 and 2014. The distributions were payable in common stock or cash at the election of our stockholders, with the cash portion of the distributions subject to certain maximum amounts. As a result of the special distributions, we paid a total of $125.5 million in 2015 and $83.3 million in 2014 and distributed 1.7 million and 1.5 million shares of common stock in 2015 and 2014, respectively. Also as a result of our conversion to a REIT, we began paying quarterly dividends in 2015. We paid an aggregate of $396.0 million of cash dividends during 2015, which consisted of $393.6 million of cash dividends paid to shareholders and $2.4 million of cash paid in lieu of stock for fractional shares upon the vesting of restricted stock units.

61


We have incurred $78.3 million in costs to support our conversion to a REIT since 2012, including $4.5 million and $49.4 million in 2015 and 2014, respectively. We expect to incur approximately $10.0 million annually in REIT compliance costs.

Operating Activities
Our cash provided by our operations is generated by colocation, interconnection, managed infrastructure and other revenues. Our primary use of cash from our operating activities include compensation and related costs, interest payments, other general corporate expenditures and taxes. The increase in net cash provided by operating activities during 20152018 compared to 20142017 was primarily due to improved operating results.results combined with incremental operating cash provided by the acquisitions of Infomart Dallas and Metronode in April 2018 and inclusion of full year operating results of the Verizon Data Center Acquisition, offset by increases in cash paid for cost of revenues, operating expenses, interest expense and income taxes. The increase in net cash provided by operating activities during 20142017 compared to 20132016 was primarily due to improved operating results combined with incremental operating cash provided by the Verizon Data Center Acquisition and other acquisitions in 2017, offset by unfavorable working capital activities such as decreasedtiming of collections of customeron our receivables and a $51.4 million increaseincreases in cash paid for cost of revenues, operating expenses, interest payments. We expect we will continue to generate cash from our operating activities during 2016.expense and income taxes.
Investing Activities
The decrease in net cash used in investing activities during 2018 compared to 2017 was primarily due to the decrease in spending for business acquisitions of approximately of $3.1 billion, primarily due to the Verizon Data Center Acquisition in 2017, partially offset by $717.4 million of higher capital expenditures and $87.3 million of higher purchases of real estate, primarily as a result of expansion activity. The increase in net cash used in investing activities during 20152017 compared to 20142016 was primarily due to a $513.9 millionthe increase in restricted cash,spending for business acquisitions of approximately of $2.2 billion, primarily related to the Verizon Data Center Acquisition, a decrease in connection with our cash and share offer for TelecityGroup, $245.6proceeds from asset sales of $803.8 million, net of cash for our acquisition of Bit-isle and Nimbo, $207.9$265.4 million of higher capital expenditures and $67.0 million of higher purchases of real estate, primarily as a result of expansion activity and $21.5 million of higher purchase of real estate, partially offset by $187.0 million of lower purchase of investments and $87.6 million of higher sales and maturities of investment. The decrease in net cash used in investing activities during 2014 compared to 2013 was primarily due to $423.0 million of lower purchases of investments, $295.7 million of higher sales and maturities of investments, $57.5 million of lower real estate purchases and $49.3 million of lower business acquisition spending, partially offset by $87.8 million of higher capital expenditures as a result of more IBX expansion activity.
In May 2015, we announced a cash and share offer valued at £2.4 billion or $3.8 billion U.S dollars for the entire issued and outstanding share capital of TelecityGroup. The acquisition closed on January 15, 2016.
During 2016,2019, we expect thatanticipate our IBX expansion construction activity will be greater thanincrease from our 20152018 levels. However, ifIf the opportunity to expand is greater than planned and we have sufficient funding to pursue such expansion opportunities, we may further increase the level of capital expendituresexpenditure to support this growth as well as pursue additional business acquisitions, propertyand real estate acquisitions or joint ventures.

In connection with certain of our leases and other contracts requiring deposits, we entered into 3042 irrevocable letters of credit totaling $55.3$68.5 million under the revolving credit facility. These letters of credit were provided in lieu of cash deposits under the revolving credit facility.deposits. If the landlords for these IBX leases decide to draw down on these letters of credit triggered by an event of default under the lease, we will be required to fund these letters of credit either through cash collateral or borrowing under the revolving credit facility. These contingent commitments are not reflected in the table above.
We had accrued liabilities related to uncertain tax positions totaling approximately $26.8$106.9 million as of December 31, 2015.2018. These liabilities, which are reflected on our balance sheet, are not reflected in the table above since it is unclear when these liabilities will be paid.
Primarily as a result of our various IBX data center expansion projects, as of December 31, 2015,2018, we were contractually committed for $256.8$687.6 million of unaccrued capital expenditures, primarily for IBX equipment not yet delivered and labor not yet provided in connection with the work necessary to complete construction and open these IBX data centers prior to making them available to customers for installation. This amount, which is expected to be paid during 20162019 and thereafter, is reflected in the table above as “other"other contractual commitments."
We had other non-capital purchase commitments in place as of December 31, 2015,2018, such as commitments to purchase power in select locations and other open purchase orders, which contractually bind us for goods, services or servicesarrangements that may contain

embedded leases to be delivered or provided during 20162019 and beyond. Such other purchase commitments as of December 31, 2015,2018, which total $352.2$837.5 million, are also reflected in the table above as “other"other contractual commitments."
In addition, althoughAdditionally, we are not contractually obligated to do so, we expect to incur additional capital expendituresentered into lease agreements in various locations for a total lease commitment of approximately $359.6$262.2 million, excluding potential lease renewals. These lease agreements will commence between February 2019 and May 2020 with lease terms of 5 to $459.6 million, in addition to the $609.0 million in contractual commitments discussed above as of December 31, 2015, in our various IBX data center expansion projects during 2016 and thereafter in order to complete the work needed to open these IBX data centers. These non-contractual capital expenditures30 years, which are not reflected in the table above. If we so choose, whether due to economic factors or other considerations, we could delay these non-contractual capital expenditure commitments to preserve liquidity.
Other Off-Balance-Sheet Arrangements
We have various guarantor arrangements with both our directors and officers and third parties, including customers, vendors and business partners. As of December 31, 2015,2018, there were no significant liabilities recorded for these arrangements. For additional information, see “Guarantor Arrangements”"Guarantor Arrangements" in Note 1415 of the Notes to Consolidated Financial Statements in Item 8 of this Annual Report on Form 10-K.
Critical Accounting Policies and Estimates
Our consolidated financial statements are prepared in accordance with generally accepted accounting principles in the U.S. (“GAAP”).GAAP. The preparation of our financial statements requires management to make estimates and assumptions about future events that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, management evaluates the accounting policies, assumptions, estimates and judgments to ensure that our consolidated financial statements are presented fairly and in accordance with GAAP. Management bases its assumptions, estimates and judgments on historical experience, current trends and various other factors that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. However, because future events and their effects cannot be determined with certainty, actual results may differ from these assumptions and estimates, and such differences could be material.
Our significant accounting policies are discussed in Note 1 to Consolidated Financial Statements in Item 8 of this Annual Report on Form 10-K. Management believes that the following critical accounting policies and estimates are the most critical to aid in fully understanding and evaluating our consolidated financial statements, and they require significant judgments, resulting from the need to make estimates about the effect of matters that are inherently uncertain:
Accounting for income taxes;
Accounting for business combinations;
Accounting for impairment of goodwill; and
Accounting for property, plant and equipment.

Description

Judgments and Uncertainties
Effect if Actual Results Differ Fromfrom Assumptions
Accounting for Income Taxes.

Deferred tax assets and liabilities are recognized based on the future tax consequences attributable to temporary differences that exist between the financial statement carrying value of assets and liabilities and their respective tax bases, and operating loss and tax credit carryforwards on a taxing jurisdiction basis. We measure deferred tax assets and liabilities using enacted tax rates that will apply in the years in which we expect the temporary differences to be recovered or settled.
 
The accounting standard for income taxes requires a reduction of the carrying amounts of deferred tax assets by recording a valuation allowance if, based on the available evidence, it is more likely than not (defined by the accounting standard as a likelihood of more than 50%) that such assets will not be realized.

A tax benefit from an uncertain income tax position may be recognized in the financial statements only if it is more likely than not that the position is sustainable, based solely on its technical merits and consideration of the relevant taxing authority’sauthority's widely understood administrative practices and precedents.

The TCJA included a Global Intangible Low-Taxed Income ("GILTI") provision that increases U.S. federal taxable income by certain foreign subsidiary income in the year it is earned. Our accounting policy is to treat any tax on GILTI inclusions as a current period cost included in the tax expense in the year incurred. The Company believes the GILTI inclusion provision will result in no financial statement impact provided the Company satisfies its REIT distribution requirement with respect to the GILTI inclusions.

Our qualification and taxation as a REIT depends on our satisfaction of certain asset, income, organizational, distribution, stockholder ownership and other requirements on a continuing basis. Our ability to satisfy quarterly asset tests depends upon our analysis and the fair market values of our REIT and non-REIT assets.




The valuation of deferred tax assets requires judgment in assessing the likely future tax consequences of events that have been recognized in our financial statements or tax returns. Our accounting for deferred tax consequences represents our best estimate of those future events.


In assessing the need for a valuation allowance, we consider both positive and negative evidence related to the likelihood of realization of the deferred tax assets. If, based on the weight of that available evidence, it is more likely than not the deferred tax assets will not be realized, we record a valuation allowance. The weight given to the positive and negative evidence is commensurate with the extent to which the evidence may be objectively verified.


This assessment, which is completed on a taxing jurisdiction basis, takes into account a number of types of evidence, including the following: 1) the nature, frequency and severity of current and cumulative financial reporting losses, 2) sources of future taxable income and 3) tax planning strategies.


In assessing the tax benefit from an uncertain income tax position, the tax position that meets the more-likely-than-not recognition threshold is initially and subsequently measured as the largest amount of tax benefit that is greater than 50% likely of being realized upon ultimate settlement with a taxing authority that has full knowledge of all relevant information.


For purposes of the quarterly REIT asset tests, we estimate the fair market value of assets within our QRSs and TRSs using a discounted cash flow approach, by calculating the present value of forecasted future cash flows. We apply discount rates based on industry benchmarks relative to the market and forecasting risks. Other key assumptions used to estimate the fair market value of assets in QRSs and TRSs include projected revenue growth, operating margins and forecasted capital expenditure. We revisit key assumptions periodically to reflect any changes due to business or economic environment.



As of December 31, 20152018 and 2014,2017, we recorded ahad net total of net deferred tax liabilities of $39.5$189.6 million and $100.8$186.3 million, respectively. As of December 31, 20152018 and 2014,2017, we had a total valuation allowance of $29.9$57.0 million and $27.2$84.6 million, respectively. During the year ended December 31, 2015 and 2014, we decided to provide a partial release of valuation allowance against the net deferred tax assets associated with certain foreign operating entities, which resulted in an insignificant income tax benefit in our results of operations.

Our decisions to release our valuation allowances were based on our belief that the operations of these jurisdictions had achieved a sufficient level of profitability and will sustain a sufficient level of profitability in the future to support the release of these valuation allowances based on relevant facts and circumstances. However, if our assumptions on the future performance of these jurisdictions prove not to be correct and these jurisdictions are not able to sustain a sufficient level of profitability to support the associated deferred tax assets on our consolidated balance sheet, we will have to impair our deferred tax assets through an additional valuation allowance, which would impact our financial position and results of operations in the period such a determination is made.

Our remaining valuation allowance as of December 31, 2015 was $29.9 million and primarily relates to certain of our subsidiaries outside of the U.S. If and when we releasereduce our remaining valuation allowances, it willmay have a favorable impact to our financial position and results of operations in the periods when such determinations are made. We will continue to assess the need for our valuation allowances, by country or location, in the future

During the year ended December 31, 2018, we released the full valuation allowances against the deferred tax assets of one of our Brazilian legal entities, certain Japanese entities and partial valuation allowance against the Spanish deferred tax assets acquired from the Itconic acquisition as a result of legal entities reorganizations in the Americas, APAC and EMEA regions. As part of the purchase accounting determination for the Metronode Acquisition, we provided full valuation allowance against certain deferred tax assets in Australia that are not expected to be realizable in the foreseeable future.
During the year ended December 31, 2017, we provided full and partial valuation allowances against the Spanish and Turkish deferred tax assets acquired from the Itconic and Zenium data center acquisitions, respectively. In addition, we set up a full valuation allowance against the deferred tax asset associated with excess tax goodwill established as a result of a reorganization in Brazil.

As of December 31, 20152018 and 2014,2017, we had unrecognized tax benefits of $30.8$150.9 million and $36.1$82.4 million, respectively, exclusive of interest and penalties. During the year ended December 31, 2015,2018, the unrecognized tax benefits decreasedincreased by $5.3$68.5 million primarily due to an agreement with Dutch Tax Authorities on the availabilityMetronode Acquisition and the reorganization of historical loss carry-forwards to offset future profits generated by the Dutch fiscal unity.Spanish entities from the Itconic acquisition.

The unrecognized tax benefits of $30.8$114.9 million as of December 31, 2015,2018, if subsequently recognized, will affect our effective tax rate favorably at the time when such benefits are recognized.

Accounting for Business Combinations

In accordance with the accounting standard for business combinations, we allocate the purchase price of an acquired business to its identifiable assets and liabilities based on estimated fair values. The excess of the purchase price over the fair value of the assets acquired and liabilities assumed, if any, is recorded as goodwill.
 
We use all available information to estimate fair values. We typically engage outside appraisal firms to assist in determining the fair value determination of identifiable intangible assets such as customer contracts, leases and any other significant assets or liabilities and contingent consideration.consideration, as well as the estimated useful life of intangible assets. We adjust the preliminary purchase price allocation, as necessary, up to one year after the acquisition closing date if we obtain more information regarding asset valuations and liabilities assumed.



Our purchase price allocation methodology contains uncertainties because it requires assumptions and management’smanagement's judgment to estimate the fair value of assets acquired and liabilities assumed at the acquisition date. Key judgments used to estimate the fair value of intangible assets include projected revenue growth and operating margins, discount rates, customer attrition rates, as well as the estimated useful life of intangible assets. Management estimates the fair value of assets and liabilities based upon quoted market prices, the carrying value of the acquired assets and widely accepted valuation techniques, including discounted cash flows and market multiple analyses. Our estimates are inherently uncertain and subject to refinement. Unanticipated events or circumstances may occur which could affect the accuracy of our fair value estimates, including assumptions regarding industry economic factors and business strategies.



During the last three years, we have completed threea number of business combinations, including the Bit-isleMetronode Acquisition and the Infomart Dallas Acquisition in April 2018, the Itconic Acquisition and the Zenium data center acquisition in November 2015,October 2017, the NimboVerizon Data Center Acquisition in May 2017, the IO Acquisition in February 2017, the Paris IBX Data Center Acquisition in August 2016 and the TelecityGroup acquisition in January 20152016. In 2018, we have finalized the purchase price allocation for the Verizon Data Center, Itconic and the Frankfurt Kleyer 90 Carrier Hotel acquisition in October 2013.Zenium data center acquisitions. The purchase price allocation for the Bit-isleIO, Paris IBX Data Center and Frankfurt Kleyer 90 Carrier HotelTelecityGroup acquisitions were completed in prior years.

As of December 31, 2018, 2017 and 2016, we had net intangible assets of $2.3 billion, $2.4 billion and $719.2 million, respectively. We recorded amortization expense for intangible assets of $203.4 million, $177.0 million and $122.9 million for the fourth quarters of 2015years ended December 31, 2018, 2017 and 2013,2016, respectively.
 
We do not believe there is a reasonable likelihood that there will be a material change in the estimates or assumptions we used to complete the purchase price allocations and the fair value of assets acquired and liabilities assumed. However, if actual results are not consistent with our estimates or assumptions, we may be exposed to losses or gains that could be material, which would be recorded in our consolidated statements of operations in 20162019 or beyond.

Accounting for Impairment of Goodwill and Other Intangible Assets

In accordance with the accounting standard for goodwill and other intangible assets, we perform goodwill and other intangible assets impairment reviews annually, or whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable.

DuringWe complete the year ended December 31, 2014, we changed our annual goodwill impairment testing date from November 30th to October 31st of each year, commencing on October 31, 2014.
During the year ended December 31, 2015, we elected to assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit in which goodwill resides is less than its carrying value.

During the year ended December 31, 2015, we completed annual goodwill impairment assessment offor the Americas, reporting unit, the EMEA reporting unit and the Asia-Pacific reporting unit and concluded that it is more likely than not thatunits to determine if the fair valuevalues of thesethe reporting units exceeded their carrying value, goodwill isvalues.

During the year ended December 31, 2015,
To perform annual goodwill impairment assessment, we elected to assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying valuevalue. This analysis requires assumptions and estimates before performing the two-stepquantitative goodwill impairment test, where the assessment requires assumptions and estimates derived from a review of our actual and forecasted operating results, approved business plans, future economic conditions and other market data.
There were no specific factors present in 2018 or 2017 that indicated a potential goodwill impairment.
Prior to 2015, when we elected to perform
We performed our annual review of other intangible assets by assessing if there were events or changes in circumstances indicating that the first stepcarrying amount of an asset may not be recoverable, such as a significant decrease in market price of an asset, a significant adverse change in the two-step goodwill impairment test, weextent or manner in which an asset is being used, botha significant adverse change in legal factors or business climate that could affect the income and market approach.

As of December 31, 2015,2018, goodwill attributable to the Americas, reporting unit, the EMEA reporting unit and the Asia-Pacific reporting unitunits was $460.2$1.7 billion, $2.5 billion and $616.4 million, $374.1 million and $228.9 million, respectively.


Future events, changing market conditions and any changes in key assumptions may result in an impairment charge. While we have not recorded an impairment charge against our goodwill to date, the development of adverse business conditions in our Americas, EMEA or Asia-Pacific reporting units, such as higher than anticipated customer churn or significantly increased operating costs, or significant deterioration of our market comparables that we use in the market approach, could result in an impairment charge in future periods.


The balance of our other intangible assets, net, for the year ended December 31, 2018 was $2.3 billion. While we have not recorded an impairment charge against our other intangible assets to date, future events or changes in circumstances, such as a significant decrease in market price of an asset, a significant adverse change in the extent or manner in which an asset is being used, a significant adverse change in legal factors or business climate, may result in an impairment charge in future periods.

Any potential impairment charge against our goodwill and other intangible assets would not exceed the amounts recorded on our consolidated balance sheets.

Accounting for Property, Plant and Equipment


We have a substantial amount of property, plant and equipment recorded on our consolidated balance sheet. The vast majority of our property, plant and equipment represent the costs incurred to build out or acquire our IBX data centers. Our IBX data centers are long-lived assets. The majority of our IBX data centers are in properties that are leased. We depreciate our property, plant and equipment using the straight-line method over the estimated useful lives of the respective assets (subject to the term of the lease in the case of leased assets or leasehold improvements and integral equipment located in leased properties).


Accounting for property, plant and equipment includes determining the appropriate period in which to depreciate such assets, making assessments for leased properties to determine whether they are capital or operating leases, determining if construction projects performed at leased properties trigger build-to-suit lease accounting, assessing such assets for potential impairment, capitalizing interest during periods of construction and assessing the asset retirement obligations required for certain leased properties that require us to return the leased properties back to their original condition at the time we decide to exit a leased property.


While there
Judgments are numerous judgments and uncertainties involvedrequired in accounting for property, plant and equipment that are significant, arriving at the estimated useful life of an asset requires the most critical judgment for us and changes to these estimates would have the most significant impact on our financial position and results of operations. When we lease a property for our IBX data centers, we generally enter into long-term arrangements with initial lease terms of at least 8-10 years and with renewal options generally available to us. DuringIn the next several years, a number of leases for our IBX data centers will come up for renewal. As we start approaching the end of these initial lease terms, we will need to reassess the estimated useful lives of our property, plant and equipment. In addition, we may find that our estimates for the useful lives of non-leased assets may also need to be revised periodically. We periodically review the estimated useful lives of certain of our property, plant and equipment and changes in these estimates in the future are possible.


Another area of judgment for us in connection with our property, plant and equipment is related to lease accounting. MostSome of our IBX data centers are leased. Each time we enter into a new lease or lease amendment for one of our IBX data centers, we analyze each lease or lease amendment for the proper accounting. This requires certain judgments on our part such as establishing the lease term to include in a lease test, establishing the remaining estimated useful life of the underlying property or equipment and estimating the fair value of the underlying property or equipment, and establishing the incremental borrowing rate to calculate the present value of the minimum lease payment for the lease test. All of these judgments are inherently uncertain. Different assumptions or estimates could result in a different accounting treatment for a lease.


The assessment of long-lived assets for impairment requires assumptions and estimates of undiscounted and discounted future cash flows. These assumptions and estimates require significant judgment and are inherently uncertain.




WeAs of December 31, 2018, 2017 and 2016, we had property, plant and equipment of $11.0 billion, $9.4 billion, and $7.2 billion, respectively. During the years ended December 31, 2018, 2017 and 2016, we recorded depreciation expense of $1.0 billion, $865.5 million, and $714.3 million, respectively. While we evaluated the appropriateness, we did not revise the estimated useful lives of our property, plant and equipment during the years ended December 31, 20152018, 2017 and 2013. During the quarter ended December 31, 2014, we revised the estimated useful lives of certain of our property, plant and equipment. As a result, we recorded an insignificant amount of higher depreciation expense for the quarter ended December 31, 2014 due to the reduction of the estimated useful lives of certain of our property, plant and equipment. We undertook this review due to our determination that we were generally using certain of our existing assets over a shorter period than originally anticipated and, therefore, the estimated useful lives of certain of our property, plant and equipment has been shortened. This change was accounted for as a change in accounting estimate on a prospective basis effective October 1, 2014 under the accounting standard for change in accounting estimates.

As of December 31, 2015, 2014 and 2013, we had property, plant and equipment of $5.6 billion, $5.0 billion, and $4.6 billion, respectively. During the years ended December 31, 2015, 2014 and 2013, we recorded depreciation expense of $498.1 million, $453.9 million, and $405.5 million, respectively.2016. Further changes in our estimated useful lives of our property, plant and equipment could have a significant impact on our results of operations.

As of December 31, 20152018, 2017 and 2014,2016, we had property, plant and equipment under capital leases of $823.6 million, $760.4 million and other financing obligations of $1.5 billion, $1.1 billion and $949.0$715.3 million, respectively.

ITEM 7A    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
ITEM 7A.QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Market Risk
The following discussion about market risk involves forward-looking statements. Actual results could differ materially from those projected in the forward-looking statements. We may be exposed to market risks related to changes in interest rates and foreign currency exchange rates and fluctuations in the prices of certain commodities, primarily electricity.
We employ foreign currency forward exchange contracts for the purpose of hedging certain specifically-identified exposures. The use of these financial instruments is intended to mitigate some of the risks associated with fluctuations in currency exchange rates, but does not eliminate such risks. We do not use financial instruments for trading or speculative purposes.
Investment Portfolio Risk
We maintain an investment portfolio of various holdings, types, and maturities that is prioritized on meeting REIT asset requirements. All of our marketable securities are designated as available-for-sale and, therefore, are recorded on our consolidated balance sheets at fair value with unrealized gains or losses reported as a component of other comprehensive income,changes in fair values recognized in net of tax.income. We consider various factors in determining whether we should recognize an impairment charge for our securities, including the length of time and extent to which the fair value has been less than our cost basis and our intent and ability to hold the investment for a period of time sufficient to allow for any anticipated recovery. We anticipate that we will recover the entire cost basis of these securities and have determined that no other-than-temporary impairments associated with credit losses were required to be recognized during the year ended December 31, 2015.2018.
As of December 31, 2015,2018, our investment portfolio of cash equivalents and marketable securities consisted of money market fund investments, U.S. government securities,funds, certificates of deposits and publicly traded equity securities and publicly traded fixed income securities. The amount in our investment portfolio that could be susceptible to market risk totaled $1.1 billion.$124.1 million.
Interest Rate Risk 
Our primary objective for holding fixed income securities isWe are exposed to achieve an appropriate investment return consistent with preserving principal and managing risk which meets asset measurement requirements for REIT qualification. At any time, a sharp rise in interest rates or credit spreads could have a material adverse impact on the fair value of our fixed income investment portfolio. Securities with longer maturities are subject to a greater interest rate risk than those with shorter maturities. As of December 31, 2015, the average duration ofrelated to our portfolio was less than one year. An immediate hypothetical shift in the yield curves of plus or minus 50 basis points from their position as of December 31, 2015 would not have a material impact on the fair value of our investment portfolio. This sensitivity analysis assumes a parallel shift of all interest rates, however, interest rates do not always move in such a manner and actual results may differ materially. We monitor our interest rate and credit risk, including our credit exposures to specific rating categories and to individual issuers. There were no impairment charges on our cash equivalents and fixed income securities during the year ended December 31, 2015.
outstanding debt. An immediate 10% increase or decrease in current interest rates from their position as of December 31, 20152018 would not have a material impact on our debt obligationsinterest expense due to the fixed nature ofcoupon rate on the majority of our debt obligations. However, the interest expense associated with our senior credit facility the Brazil financings and bridge term loan, whichloans, that bear interest at variable rates, could be affected. For every 100 basis point change in interest rates, our annual interest expense could increase by a total of approximately $12.7 million or decrease by a total of approximately $6.9$5.6 million based on the total balance of our primary borrowings under the term loan A facility, revolving credit facility, bridge term loan and the Brazil financingsTerm Loan Facility as of December 31, 2015.2018. As of December 31, 2015,2018, we had not employed any interest rate derivative products against our debt obligations. However, we may enter into interest rate hedging agreements in the future to mitigate our exposure to interest rate risk.
The fair value of our long-term fixed interest rate debt is subject to interest rate risk. Generally, the fair value of fixed interest rate debt will increase as interest rates fall and decrease as interest rates rise. These interest rate changes may affect the fair value of the fixed interest rate debt but do not impact our earnings or cash flows. The fair value of our convertible debt, which is traded in the market, is based on quoted market prices. The fair value of ourmortgage and loans payable and 5.000% Infomart Senior Notes, which are not traded in the market, is estimated by considering our credit rating, current rates available to us for debt of the same remaining maturities and the terms of the debt. The fair value of our other senior notes, which are traded in the market, was based on quoted market prices. The following table represents the carrying value and estimated fair value of our mortgage and loans payable and senior notes and convertible debt as of (in thousands):

Foreign Currency Risk
A significant portion of our revenue is denominated in U.S. dollars, however, approximately 48.5%55.3% of our revenues and 48.6%53.5% of our operating costs are attributable to Brazil, Canada, Colombia and the EMEA and Asia-Pacific regions, and a large portion of those revenues and costs are denominated in a currency other than the U.S. dollar, primarily the Brazilian Reals, Canadian dollar,Euro, British pound, Euro, Swiss franc, United Arab Emirates dirham, AustralianJapanese yen, Singapore dollar, Chinese Yuan, Hong Kong dollar, Japanese yenAustralian dollar and Singapore dollar. As a result, our operating results and cash flows are impacted by currency fluctuations relative to the U.S. dollar.Brazilian real. To protect against certain reductions in value caused by changes in currency exchange rates, we have established a risk management program to offset some of the risk of carrying assets and liabilities denominated in foreign currencies. As a result, we have entered into foreign currency forward contracts to manage the risk associated with certain foreign currency-denominated assets and liabilities. We entered into foreign currency forward contracts to help manage ourthe exposure to foreign currency exchange rate fluctuations, forwe have implemented a number of hedging programs, in particular (i) a cash flow hedging program

to hedge the forecasted revenues and expenses in our EMEA region.region, (ii) a balance sheet hedging program to hedge the remeasurement of monetary assets and liabilities denominated in foreign currencies, and (iii) a net investment hedging program to hedge the long term investments in our foreign subsidiaries. Our risk management program reduces,hedging programs reduce, but doesdo not entirely eliminate, the impact of currency exchange rate movements and its impact on theour consolidated balance sheets, statements of operations.operations and statements of cash flows. As of December 31, 2015,2018, the outstanding foreign currency forward contracts had maturities of less thanup to two years.
We have entered into various foreign currency debt obligations. As of December 31, 2018, the total principal amount of foreign currency debt obligations was $4.5 billion, including $3.2 billion denominated in Euro, $612.7 million denominated in British Pound, $427.8 million denominated in Japanese Yen and $304.0 million denominated in Swedish Krona. As of December 31, 2018, we have designated $4.1 billion of the total principal amount of foreign currency debt obligations as net investment hedges against our net investments in foreign subsidiaries. For a net investment hedge, changes in the fair value of the hedging instrument designated as a net investment hedge, except the ineffective portion and forward points, are recorded as a component of other comprehensive income in the consolidated balance sheets. We did not record any ineffectiveness during the year ended December 31, 2018.
Fluctuations in the exchange rates between these foreign currencies (i.e. Euro, British Pound, Swedish Krona and Japanese Yen) and the U.S. Dollar will impact the amount of U.S. dollars that we will require to settle the foreign currency debt obligations at maturity. If the U.S. Dollar would have been weaker or stronger by 10% in comparison to these foreign currencies as of December 31, 2018, we estimate our obligation to cash settle the principal of these foreign currency debt obligations in U.S. dollars would have increased or decreased by approximately $449.5 million respectively.
For the foreseeable future, we anticipate that more thanapproximately 50% of our revenues and operating costs will continue to be generated and incurred outside of the U.S. in currencies other than the U.S. dollar. During fiscal 2015,2018, the U.S. dollar wasbecame generally strongstronger relative to certain of the currencies of the foreign countries in which we operate. This overall strengthstrengthening of the U.S. dollar had a negative impact on our consolidated results of operations because the foreign denominations translated into less U.S. dollars. In future periods, the volatility of the U.S. dollar as compared to the other currencies in which we do business could have a significant impact on our consolidated financial position and results of operations including the amount of revenue that we report in future periods.
Excluding consideration from hedging contracts, an immediateWith the existing cash flow hedges in place, a hypothetical additional 10% appreciation in current foreign exchange rates asstrengthening of the U.S. dollar during the year ended December 31, 20152018 would have resulted in a reduction of our revenues and operating expenses, including depreciation and amortization expenses, for the year by approximately $137.1 million and $145.1 million, respectively.
With the existing cash flow hedges in place, a hypothetical additional 10% weakening of the U.S. dollar during the year ended December 31, 2018 would have resulted in an increase of $130.8our revenues and operating expenses, including depreciation and amortization expenses, for the year by approximately $175.1 million and $23.1$179.4 million, in revenue and net income before taxes. Excluding consideration from hedging contracts, an immediate 10% depreciation in current foreign exchange rates as of December 31, 2015 would have resulted in a decrease of $128.4 million and $25.2 million in revenue and net income before taxes.respectively.
We may enter into additional hedging activities in the future to mitigate our exposure to foreign currency risk as our exposure to foreign currency risk continues to increase due to our growing foreign operations; however, we do not currently intend to eliminate all foreign currency transaction exposure.
Commodity Price Risk
Certain operating costs incurred by us are subject to price fluctuations caused by the volatility of underlying commodity prices. The commodities most likely to have an impact on our results of operations in the event of price changes are electricity, supplies and equipment used in our IBX data centers. We closely monitor the cost of electricity at all of our locations. We have entered into several power contracts to purchase power at fixed prices during 2014 and beyond in certain locations in the U.S., Australia, Brazil, France, Germany, Japan, the Netherlands, Singapore and the United Kingdom.
In addition, as we are building new, or expanding existing, IBX data centers, we are subject to commodity price risk for building materials related to the construction of these IBX data centers, such as steel and copper. In addition, the lead-time to procure certain pieces of equipment, such as generators, is substantial. Any delays in procuring the necessary pieces of equipment for the construction of our IBX data centers could delay the anticipated openings of these new IBX data centers and, as a result, increase the cost of these projects.

We do not currently employ forward contracts or other financial instruments to address commodity price risk other than the power contracts discussed above.

Based on this evaluation, our Chief Executive Officer and our Chief Financial Officer concluded that our disclosure controls and procedures were effective at the reasonable assurance level as of December 31, 2015.2018.
Management’sManagement's Report on Internal Control Over Financial Reporting
Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rule 13a-15(f). Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
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 our evaluation under the framework in Internal Control – Integrated Framework (2013), our management concluded that our internal control over financial reporting was effective as of December 31, 2015.2018.
The evaluation of the effectiveness of our internal control over financial reporting as of December 31, 2015 did not include the internal controls of Bit-isle Inc. We excluded Bit-isle Inc. from our assessment of internal control over financial reporting as of December 31, 2015 as it was acquired in November 2015. Bit-isle Inc. is our wholly-owned subsidiary whose total assets represented 4% and total revenues represented 1% of the related consolidated financial statements amounts as of and for the year ended December 31, 2015.
The effectiveness of our internal control over financial reporting as of December 31, 20152018 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which is included herein on page F-1 of this Annual Report on Form 10-K.
Limitations on the Effectiveness of Controls
Our management, including our Chief Executive Officer and Chief Financial Officer, believes that our disclosure controls and procedures and internal control over financial reporting are designed and operated to be effective at the reasonable assurance level. However, our management does not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must

70


reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected. These inherent limitations include the realities that judgments in decision making can be faulty, and that breakdowns can occur because of a simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people or by management override of the controls. The design of any system of controls is also based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, controls may become inadequate because of changes in conditions, or the degree of compliance with policies or procedures may deteriorate. Because of the inherent limitations in a cost effective control system, misstatements due to error or fraud may occur and not be detected.

Changes in Internal Control Over Financial Reporting
There was no change in our internal controls over financial reporting during the fourth quarter of fiscal 20152018 that has materially affected, or is reasonable likely to affect, our internal controls over financial reporting. We implemented certain internal controls related to the adoption of ASC 606, Revenue from Contracts with Customers, to ensure we adequately evaluated our contracts and properly assessed the impact of the new revenue recognition standard on our financial statements to facilitate its adoption effective January 1, 2018.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and
Shareholders Stockholders of Equinix, Inc.:
Opinions on the Financial Statements and Internal Control over Financial Reporting
In our opinion,We have audited the accompanying consolidated financial statements listed in the index appearing under Item 15(a)(1) present fairly, in all material respects, the financial positionbalance sheets of Equinix, Inc. and its subsidiaries at(the “Company”) as of December 31, 20152018 and December 31, 2014,2017, and the resultsrelated consolidated statements of their operations, comprehensive income (loss), stockholder’s equity and theirother comprehensive income (loss), and cash flows for each of the three years in the period ended December 31, 20152018, including the related notes and financial statement schedule listed in the accompanying index appearing under item 15(a)(2) (collectively referred to as the “consolidated financial statements”). We also have audited the Company's internal control over financial reporting as of December 31, 2018, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2018 and 2017, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2018 in conformity with accounting principles generally accepted in the United States of America. In addition, in our opinion, the financial statement schedulelisted in the accompanying indexpresents fairly, in all material respects, the information set forth therein when read in conjunction with the related consolidatedfinancial statements. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2015,2018, based on criteria established in Internal Control - Integrated Framework (2013)issued by the CommitteeCOSO.
Change in Accounting Principle
As discussed in Note 1 to the consolidated financial statements, the Company changed the manner in which it accounts for revenue from contracts with customers as of Sponsoring Organizations of the Treadway Commission (COSO). January 1, 2018.

Basis for Opinions

The Company's management is responsible for these consolidated financial statements, and financial statement schedule, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management's Report on Internal Control over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on thesethe Company's consolidated financial statements on the financial statement schedule, and on the Company's internal control over financial reporting based on our integrated audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States).PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence supportingregarding the amounts and disclosures in the consolidated financial statements, assessingstatements. Our audits also included evaluating the accounting principles used and significant estimates made by management, andas well as evaluating the overall presentation of the consolidated financial statement presentation.statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.
As discussed in Note 1 to the consolidated financial statements, the Company changed the manner in which it classifies deferred tax assets
Definition and liabilities and debt issuance costs on the consolidated balance sheet in 2015.Limitations of Internal Control over Financial Reporting

A company’scompany's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’scompany's internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) 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 (iii) provide reasonable

assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’scompany's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
As described in Management’s Report on Internal Control over Financial Reporting, management has excluded Bit-isle, Inc. from its assessment of internal control over financial reporting as of December 31, 2015 because it was acquired by the Company in a purchase business combination during 2015. We have also excluded Bit-isle Inc. from our assessment of internal control over financial reporting. Bit-isle, Inc. is a wholly-owned subsidiary with total assets and total revenue representing approximately 4% and 1%, respectively of the consolidated financial statement amounts as of and for the year ended December 31, 2015.

Use of Estimates
The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States ("U.S.") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates. On an ongoing basis, the Company evaluates its estimates, including, but not limited to, those related to the allowance for doubtful accounts, fair values of financial instruments, intangible assets and goodwill, useful lives of intangible assets and property, plant and equipment, assets acquired and liabilities assumed from acquisitions, asset retirement obligations restructuring charges, redemption value of redeemable non-controlling interests and income taxes. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable.
Cash, Cash Equivalents and Short-Term and Long-Term Investments
The Company considers all highly liquid instruments with an original maturity from the date of purchase of three months or less to be cash equivalents. Cash equivalents consist of money market mutual funds and highly liquid debt securities of corporations and certificates of deposit with original

Equity method and cost method investmentsMethod Investments
The Company's investments in non-marketable equity securities are generally accounted under cost method accounting. The Company records the dividends declared by the investees in other income and expense in the consolidated statement of operations and records any dividends in excess of earnings as a reduction of cost of investment. The Company's other equity investments include private equity investments which are accounted undermethod. For equity method accounting.

The Company reviews these investments periodically to determine if any investments may be other-than-temporarily impaired primarily basedconsidering both qualitative and quantitative factors that may have a significant impact on the financial condition and near-term prospects of these companies and funds.investee's fair value.
Financial Instruments and Concentration of Credit Risk
Financial instruments which potentially subject the Company to concentrations of credit risk consist of cash and cash equivalents, short-term investments, long-term investments and accounts receivable. Risks associated with cash and cash equivalents, short-term investments and long-term investments are mitigated by the Company’sCompany's investment policy, which limits the Company’sCompany's investing to only those marketable securities rated at least A-1/P-1 Short Term Rating and A-/A3 Long Term Rating, as determined by independent credit rating agencies. Risk to the Company’s investment portfolio is further mitigated by its significant weighting in U.S. government securities in order to achieve REIT asset measure requirements.
A significant portion of the Company’sCompany's customer base is comprised of businesses throughout the Americas. However, a portion of the Company’sCompany's revenues are derived from the Company’sCompany's EMEA and Asia-Pacific operations. The following table sets forth percentages of the Company’sCompany's revenues by geographic region for the years ended December 31:

Property, Plant and Equipment
Property, plant and equipment are stated at the Company’sCompany's original cost or at fair value for acquired property, plant and equipment.equipment acquired through acquisitions, net of depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the respective assets. Leasehold improvements and assets acquired under capital leasesintegral equipment at leased locations are amortized over the shorter of the lease term or the estimated useful life of the asset or improvement, unless they are considered integral equipment, in which case they are amortized over the lease term.improvement.

Personal Property3-10 years
During the three months ended December 31, 2014, the Company revised the estimated useful lives of certain of its property, plant and equipment as part of a review of the related assumptions. As a result, the Company recorded an insignificant amount of higher depreciation expense for the quarter ended December 31, 2014 due to the reduction of the estimated useful lives of certain

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued)

of its property, plant and equipment. This change was accounted for as a change in accounting estimate on a prospective basis effective October 1, 2014 under the accounting standard for change in accounting estimates.The Company did not revise the estimated useful lives of the property, plant and equipment during the years ended December 31, 2015 and 2013.
The Company’sCompany's construction in progress includes direct and indirect expenditures for the construction and expansion of IBX data centers and is stated at original cost. The Company has contracted out substantially all of the construction and expansion efforts of its IBX data centers to independent contractors under construction contracts. Construction in progress includes costs incurred under construction contracts including project management services, engineering and schematic design services, design development, construction services and other construction-related fees and services. In addition, the Company has capitalized interest costs during the construction phase. Once an IBX data center or expansion project becomes operational, these capitalized costs are allocated to certain property, plant and equipment categories and are depreciated over the estimated useful life of the underlying assets.
The Company reviews its property, plant and equipment for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable such as a significant decrease in market price of an asset, a significant adverse change in the extent or manner in which an asset is being used or in its physical condition, a significant adverse change in legal factors or business climate that could affect the value of an asset or a continuous deterioration of the Company's financial condition. Recoverability of assets to be held and used is assessed by comparing the carrying amount of an asset to estimated undiscounted future net cash flows expected to be generated by the asset. If the carrying amount of the asset exceeds its estimated discounted future cash flows, an impairment charge is recognized by the amount by which the carrying amount of the asset exceeds the fair value of the asset. The Company did not record any impairment charges related to its property, plant and equipment during the years ended December 31, 2018 and 2017. However, the Company recorded an impairment charge of $7.7 million relating to assets held for sale for the year ended December 31, 2016 as described below.
The Company enters into non-cancellable lease arrangements as the lessee primarily for its data center spaces, office spaces and equipment. Assets acquired through capital leases and other financing obligations are included in property, plant and equipment, net on the consolidated balance sheets. In addition, a portion of the Company's property, plant and equipment are used for revenue arrangements which are accounted for as operating leases where the Company is the lessor.
Assets Held for Sale and Discontinued Operations
Assets and liabilities to be disposed of that meet all of the criteria to be classified as held for sale as set forth in the accounting standard for impairment or disposal of long-lived assets are reported at the lower of their carrying amounts or fair values less costs to sell. Assets are not depreciated or amortized while they are classified as held for sale. A component of a reporting entity or a group of components of a reporting entity that are disposed or meet the criteria to be classified as held for sale should be reported in discontinued operations if the disposal represents a strategic shift that has (or will have) a major effect on an entity's operations and financial results. The accounting guidance requires a business activity that, on acquisition, meets the criteria to be classified as held for sale be reported as a discontinued operation. For further information on the Company's assets held for sale and discontinued operations, see Notes 5 and 6.
Asset Retirement Costs and Asset Retirement Obligations
The fair value of a liability for an asset retirement obligation is recognized in the period in which it is incurred. The associated retirement costs are capitalized and included as part of the carrying value of the long-lived asset and amortized over the useful life of the asset. Subsequent to the initial measurement, the Company accretes the liability in relation to the asset retirement obligations over time and the accretion expense is recorded as a cost of revenue. The Company’sCompany's asset retirement obligations are primarily related to its IBX data centers, of which the majority are leased under long-term arrangements, and, in certain cases, are required to be returned to the landlords in their original condition. The majority of the Company’sCompany's IBX data center leases have been subject to significant development by the Company in order to convert them from, in most cases, vacant buildings or warehouses into IBX data centers. The majority of the Company’sCompany's IBX data centers’centers' initial lease terms expire at various dates ranging from 20172019 to 2065 and most of them enable the Company to extend the lease terms.

Goodwill and Other Intangible Assets
The Company has three reportable segments comprised of the 1) Americas, 2) EMEA and 3) Asia-Pacific geographic regions, which the Company also determined are its reporting units. Goodwill is not amortized and is tested for impairment at least annually. As of December 31, 2015,2018, the Company had goodwill attributable to its Americas, EMEA and Asia-Pacific reporting units. In 2014, the Company changed its annual goodwill impairment testing date from November 30th to October 31st of each year, commencing on October 31, 2014, to better align its annual goodwill impairment test with the timing of the Company’s budgeting and forecasting process.
The Company has the option to assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If, after assessing the qualitative factors, the Company determines that it is not more likely than not that the fair value of a reporting unit is less than its carrying value, then performing the two-stepquantitative impairment test is unnecessary. However, if the Company concludes otherwise, then it is required to perform the first step of the two-stepquantitative goodwill impairment test. The first step, identifying a potentialquantitative impairment test, which is used to identify both the existence of impairment and the amount of impairment loss, compares the fair value of a reporting unit with its carrying amount, including goodwill. If the fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is considered not impaired. If the carrying value of the reporting unit exceeds its fair value, the second step would need to be conducted; otherwise, no further steps are necessary as no potential impairment exists. The second step, measuring the impairment loss, compares the implied fair value of the reporting unit goodwill with the carrying amount of that goodwill. Anyany excess of the reporting unit goodwill carrying value over the respective implied fair value is recognized as an impairment loss.
The Company assessedassesses qualitative and quantitative factors during the fourth quarter of 2015 to determine whether it wasis more likely than not that the fair value of its Americas, reporting unit,EMEA reporting unit and Asia-Pacific reporting unit wasunits is less than its carrying value. Qualitative factors considered in the assessment include industry and market conditions, overall financial performance, and other relevant events and factors affecting the reporting unit. Additionally, as part of this analysis, the Company may perform a quantitative analysis to support the qualitative factors by evaluating sensitivities to assumptions and inputs used in measuring a reporting unit's fair value. Prior to 2015, the Company performed the first step of the two-step goodwill impairment test for its Americas, EMEA and Asia-Pacific reporting units during the quarter ended December 31, 2014 and 2013. In order to determine the fair value of each reporting unit, the Company utilizes the discounted cash flow and market methods. The Company had used both methods in its goodwill impairment tests as it believes both methods, in conjunction with each other, provide a reasonable estimate of the determination of fair value of each reporting unit – the discounted cash flow method being specific to anticipated future results of the reporting unit and the market method, which is based on the Company’s market sector including its competitors. The assumptions supporting the discounted cash flow method was determined using the Company’sCompany's best estimates as of the date of the impairment review. 
As of OctoberDecember 31, 2015,2018, 2017 and 2016, the Company concluded that it was more likely than not that goodwill attributed to the Company’sCompany's Americas, EMEA and Asia-Pacific reporting units was not impaired as the fair value of each

F-10

EQUINIX, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued)

reporting unit exceeded the carrying value of its respective reporting unit, including goodwill. In addition, the Company concluded that no events occurred or circumstances changed subsequent to October 31, 2015 through December 31, 2015 that would more likely than not reduce the fair value of the Americas, EMEA and Asia-Pacific reporting units below its carrying value. The Company has performed various sensitivity analyses on certain of the assumptions used in the discounted cash flow method, such as forecasted revenues and discount rate, and notes that no reasonably possible changes would reduce the fair value of the reporting unit to such a level that would cause an impairment charge.
Impairment assessments inherently involve judgment as to assumptions about expected future cash flows and the impact of market conditions on those assumptions. Future events and changing market conditions may impact the Company’sCompany's assumptions as to prices, costs, growth rates or other factors that may result in changes in the Company’sCompany's estimates of future cash flows. Although the Company believes the assumptions it used in testing forits evaluation of impairment are reasonable, significant changes in any one of the Company’sCompany's assumptions could produce a significantly different result. Indicators of potential impairment that might lead the Company to perform interim goodwill impairment assessments include significant and unforeseen customer losses, a significant adverse change in legal factors or in the business climate, a significant adverse action or assessment by a regulator, a significant stock price decline or unanticipated competition.
All of the Company's intangible assets are subject to amortization and are amortized using the straight-line method over their estimated period of benefit. The Company performs a review of other intangible assets for impairment by assessing events or changes in circumstances that indicate the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is assessed by comparing the carrying amount of an asset to estimated undiscounted future net cash flows expected to be generated by the asset. If the carrying amount of the asset exceeds its estimated discounted future cash flows, an impairment charge is recognized by the amount by which the carrying amount of the asset exceeds the fair value of the asset. The Company did not record any impairment charges related to its other intangible assets during the years ended December 31, 2018, 2017 and 2016.
For further information on goodwill and other intangible assets, see Note 53 and Note 7 below.
Debt Issuance Costs
Loan fees and costs are capitalized and are amortized over the life of the related loans based on the effective interest method. Such amortization is included as a component of interest expense.
The Company adopted Accounting Standards Update 2015-03, Interest - Imputation of Interest (“ASU 2015-03”), and Accounting Standards Update 2015-15, Interest - Imputation of Interest Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements (“ASU 2015-15”), during the year ended December 31, 2015.

Derivatives and Hedging Activities
The Company recognizes all derivatives on the Company's consolidated balance sheetsheets at fair value. The accounting for changes in the value of a derivative depends on whether or not the contract is for trading purposes or has been designated and qualifies for hedge accounting. In order to qualify for hedge accounting, a derivative must be considered highly effective at reducing the risk associated with the exposure being hedged. In order for a derivative to be designated as a hedge, there must be documentation of the risk management objective and strategy, including identification of the hedging instrument, the hedged item and the risk exposure, and how effectiveness is to be assessed prospectively and retrospectively. Foreign currency gains or losses associated with derivatives that do not qualify for hedge accounting are recorded within other income (expense), net in the Company’s consolidated statements of operations, with the exception of foreign currency embedded derivatives contained in certain of the Company’s customer contracts (see “Revenue Recognition” below), which are recorded within revenues in the Company’s consolidated statements of operations.
To assess effectiveness of derivatives that qualify for hedge accounting, the Company uses a regression analysis. The extent to which a hedging instrument has been and is expected to continue to be effective at achieving offsetting changes in cash flows is assessed and documented at least quarterly. Any ineffectiveness is reported in current-period earnings. If it is determined that a derivative is not highly effective at hedging the designated exposure, hedge accounting is discontinued. For qualifying cash flow hedges, the effective portion of the change in the fair value of the derivative is recorded in other comprehensive income (loss) and recognized in the consolidated statements of operations when the hedged cash flows affect earnings.earnings in the same statement of operations line item as the hedged item. The ineffective portion of cash flow hedges is immediately recognized in earnings. If it is determined that a derivative is not highly effective at hedging the designated exposure, hedge accounting is discontinued. If the hedge relationship is terminated, then the change in fair value of the derivative recorded in other comprehensive income (loss) is recognized in earnings when the cash flows that were hedged occur, consistent with the original hedge strategy. For hedge relationships discontinued because the forecasted transaction is not expected to occur according to the original strategy, any related derivative amounts recorded in other comprehensive income (loss) are immediately recognized in earnings.
Foreign currency gains or losses associated with derivatives that do not qualify for hedge accounting are recorded within other income (expense) in the Company's consolidated statements of operations, with the exception of foreign currency embedded derivatives contained in certain of the Company's customer contracts (see "Revenue Recognition" below), which are recorded within revenues in the Company's consolidated statements of operations. The Company does not use derivatives for speculative or trading purposes.

Fair Value of Financial Instruments
The carrying value of the Company’sCompany's cash and cash equivalents, short-term andinvestments, long-term investments and derivative instruments represent their fair value, while the Company’sCompany's accounts receivable, accounts payable and accrued expenses and accrued property, plant and equipment approximate their fair value due primarily to the short-term maturity of the related instruments. The fair value of the Company’sCompany's debt, which is traded in the public debt market, is based on quoted market prices. The fair value of the Company’sCompany's debt, which is not publicly traded, is estimated by considering the Company’sCompany's credit rating, current rates available to the Company for debt of the same remaining maturities and terms of the debt.
Fair Value Measurements
The Company measures and reports certain financial assets and liabilities at fair value on a recurring basis, including its investments in money market funds, and available-for-sale debt investments in other public companies, governmental units and other agencies,certificates of deposit, publicly traded equity securities and derivatives.
The Company also follows the accounting standard for the measurement of fair value for non-financial assets and liabilities on a nonrecurring basis. These include:
Non-financial assets and non-financial liabilities initially measured at fair value in a business combination or other new basis event, but not measured at fair value in subsequent reporting periods;
Reporting units and non-financial assets and non-financial liabilities measured at fair value for goodwill impairment tests;
Indefinite-lived intangible assets measured at fair value for impairment assessments;
Non-financial long-lived assets or asset groups measured at fair value for impairment assessments or disposal; and
Asset retirement obligations initially measured at fair value but not subsequently measured at fair value; and
Non-financial liabilities associated with exit or disposal activities initially measured at fair value but not subsequently measured at fair value.
For further information on fair value measurements, see Note 79 below.
Impairment
F-13

The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable such as a significant decrease in market price of a long-lived asset, a significant adverse change in legal factors or business climate that could affect the value of a long-lived asset or a continuous deterioration of the Company’s financial condition. Recoverability of assets to be held and used is assessed by comparing the carrying amount of an asset to estimated undiscounted future net cash flows expected to be generated by the asset. If the carrying amount of the asset exceeds its estimated discounted future cash flows, an impairment charge is recognized by the amount by which the carrying amount of the asset exceeds the fair value of the asset.EQUINIX, INC.

Revenue
Revenue Recognition
Equinix derives more than 90% of its revenues from recurring revenue streams, consisting primarily of (1) colocation, which includes the licensing of cabinet space and power; (2) interconnection offerings, such as cross connects and Equinix Exchange ports; (3) managed infrastructure servicessolutions and (4) other revenues consisting of rental income from tenants or subtenants. The remainder of the Company’sCompany's revenues are from non-recurring revenue streams, such as installation revenues, professional services, contract settlements and equipment sales. Revenues by service lines and geographic areas are included in segment information (see Note 17). The majority of the Company's revenue contracts are classified as licenses and accounted for in accordance with Topic 606, with the exception of certain contracts that contain lease components and are accounted for in accordance with Topic 840, Leases.
Under the revenue accounting guidance, revenues are recognized when control of these products and services is transferred to its customers, in an amount that reflects the consideration it expects to be entitled to in exchange for the products and services. Revenues from recurring revenue streams are generally billed monthly and recognized ratably over the term of the contract, generally one to three years for IBX data center colocation customers. Non-recurring installation fees, although generally paid in a lump sumupfront upon installation, are deferred and recognized ratably over the period the customer is expected to benefit from the installation.contract term. Professional service fees and equipment sales are recognized in the period in whichwhen the services were provided and representprovided. For the culminationcontracts with customers that contain multiple performance obligations, the Company accounts for individual performance obligations separately if they are distinct or as a series of a separate earnings process as long as theydistinct obligations if the individual performance obligations meet the criteriaseries criteria. Determining whether products and services are considered distinct performance obligations that should be accounted for separately versus together may require significant judgment. The transaction price is allocated to the separate recognition underperformance obligation on a relative standalone selling price basis. The standalone selling price is determined based on overall pricing objectives, taking into consideration market conditions, geographic locations and other factors.

Contract Balances
The timing of revenue recognition, billings and cash collections result in accounts receivables, contract assets and deferred revenues. A receivable is recorded at the invoice amount, net of an allowance for doubtful account and is recognized in the period when the Company has transferred products or provided services to its customers and when its right to consideration is unconditional. Payment terms and conditions vary by contract type, although terms generally include a requirement of payment within 30 to 45 days. In instances where the timing of revenue recognition differs from the timing of invoicing, the Company has determined that the Company's contracts generally do not include a significant financing component. The Company assesses collectability based on a number of factors, including past transaction history with the customer and the credit-worthiness of the customer. The Company generally does not request collateral from its customers although in certain cases the Company obtains a security interest in a customer’scustomer's equipment placed in its IBX data centers or obtains a deposit. If the Company determines that collection of a fee is not reasonably assured, the fee is deferred and revenue is recognized at the time collection becomes reasonably assured, which is generally upon receipt of cash. In addition, theThe Company also maintains an allowance for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments for which the Company had expected to collect the revenues. If the financial condition of the Company’sCompany's customers were to deteriorate or if they became insolvent, resulting in an impairment of their ability to make payments, greater allowances for doubtful accounts may be required. Management specifically analyzes accounts receivable and current economic news and trends, historical bad debts, customer concentrations, customer credit-worthiness and changes in customer payment terms when evaluating revenue recognition and the adequacy of the Company’sCompany's reserves. Any amounts that were previously recognized as revenue and subsequently determined to be uncollectibleuncollectable are charged to bad debt expense included in generalsales and administrativemarketing expense in the consolidated statements of operations. A specific bad debt reserve of up to the full amount of a particular invoice value is provided for certain problematic customer balances. An additional reserve is established for all other accounts based on the age of the invoices and an analysis of historical credits issued. Delinquent account balances are written-offwritten off after management has determined that the likelihood of collection is not probable.
A contract asset exists when the Company has transferred products or provided services to its customers, but customer payment is contingent upon satisfaction of additional performance obligations. Certain contracts include terms related to price arrangements such as price increases and free months. The Company recognizes revenues ratably over the contract term, which could potentially give rise to contract assets during certain periods of the contract term. Contract assets are recorded in other current assets and other assets in the consolidated balance sheet.
Deferred revenue (a contract liability) is recognized when the Company has an unconditional right to a payment before it transfers products or services to customers. Deferred revenue is included in other current liabilities and other liabilities, respectively, in the consolidated balance sheet.
Contract Costs
Direct and indirect incremental costs solely related to obtaining revenue contracts are capitalized as costs of obtaining a contract, when they are incremental and if they are expected to be recovered. Such costs consist primarily of commission fees and sales bonuses, as well as indirect related payroll costs. Contract costs are amortized over the estimated period of benefit on a straight-line basis. The Company elected to apply the practical expedient which allows the Company to expense contract costs when incurred, if the amortization period is one year or less.
For further information on revenue recognition, see Note 2 below.
Income Taxes
Income taxes are accounted for under the asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the year in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Valuation allowances are established when necessary to reduce deferred tax assets to the amounts that are expected more likely than not to be realized in the future. A tax benefit from an uncertain income tax position may be recognized in the financial statements only if it is more likely than not that the position is sustainable, based solely on its technical merits and consideration of the relevant taxing authority’sauthority's widely understood administrative practices and precedents.
The Company began operatingelected to be taxed as a REIT for federal income tax purposes effective January 1, 2015.

deduct the distributions made to
and its shareholders from taxable income generated by the Company's Qualified REIT Subsidiaries (“QRSs”). The Company’s dividends paid deduction generally eliminates the U.S. taxable income of the Company's QRSs, resulting in no U.S. income tax due. However, the TaxableCompany's taxable REIT Subsidiaries (“TRSs”subsidiaries ("TRSs") will continue to be subject to income taxes on any taxable income generated by them. In addition, the foreign operations of the Company will continue to be subject to local income taxes regardless of whether the foreign operations are operated as a QRSQRSs or TRS.TRSs.
The Company's qualification and taxation as a REIT depends on its satisfaction of certain asset, income, organizational, distribution, stockholder ownership and other requirements on a continuing basis. The Company's ability to satisfy quarterly asset tests depends upon its analysis and the fair market values of its REIT and non-REIT assets. For purposes of the quarterly REIT asset tests, the Company recognizes interestestimates the fair market value of assets within its QRSs and penalties relatedTRSs using a discounted cash flow approach, by calculating the present value of forecasted future cash flows. The Company applies discount rates based on industry benchmarks relative to unrecognized tax benefits within income tax benefit (expense)the market and forecasting risks. Other key assumptions used to estimate the fair market value of assets in the consolidated statements of operations.QRSs and TRSs include projected revenue growth, operating margins, and forecasted capital expenditures. The Company revisits key assumptions periodically to reflect any changes due to business or economic environment.
Stock-Based Compensation
Stock-based compensation cost is measured at the grant date for all stock-based awards made to employees and directors based on the fair value of the award and is recognized as expense over the requisite service period, which is generally the vesting period.
The Company grants restricted stock units to its employees and these equity awards generally have only a service condition. The Company grants restricted stock units to its executives and these awards generally have a service and performance condition or a service and market condition. To date, any performance conditions contained in an equity award are tied to the financial performance of the Company or a specific region of the Company. The Company assesses the probability of meeting these performance conditions on a quarterly basis. The majority of the Company’sCompany's equity awards vest over four years, although certain of the equity awards for executives vest over a range of two to four years. The valuation of restricted stock units with only a service condition or a service and performance condition requires no significant assumptions as the fair value for these types of equity awards is based solely on the fair value of the Company’sCompany's stock price on the date of grant. The Company uses a Monte Carlo simulation option-pricing model to determine the fair value of restricted stock units with a service and market condition.
The Company uses the Black-Scholes option-pricing model to determine the fair value of its employee stock purchase plan. The determination of the fair value of shares purchased under the employee stock purchase plan is affected by assumptions regarding a number of complex and subjective variables including the Company’sCompany's expected stock price volatility over the term of the awards and actual and projected employee stock purchase behaviors. The Company estimated the expected volatility by using the average historical volatility of its common stock that it believed was best representative of future volatility. The risk-free interest rate used was based on U.S. Treasury zero-coupon issues with remaining terms similar to the expected term of the equity awards. The expected dividend rate used in 2015 was based on average dividend yields and the expected dividend rate used prior to 2015 was zero as the Company did not anticipate paying dividends. The expected term used was equal to the term of each purchase window.
The accounting standard for stock-based compensation does not allow the recognition of unrealized tax benefits associated with the tax deductions in excess of the compensation recorded (excess tax benefit) until the excess tax benefit is realized (i.e., reduces taxes payable). TheIn periods prior to 2017, the Company recognizesrecognized the benefit from stock-based compensation in equity when the excess tax benefit is realized by following the “with-and-without”"with-and-without" approach. Upon adoption of ASU No. 2016-09, Compensation - Stock Compensation (Topic 718) on January 1, 2017, the Company records the excess tax benefits from stock-based compensation as income tax expense through the statement of operations instead of additional paid-in capital as required under the previous guidance.
For further information on stock-based compensation, see Note 1213 below.
Foreign Currency Translation
The financial position of foreign subsidiaries is translated using the exchange rates in effect at the end of the period, while income and expense items are translated at average rates of exchange during the period. Gains or losses from translation of foreign operations where the local currency is the functional currency are included as other comprehensive income (loss). The net gains and losses resulting from foreign currency transactions are recorded in net income (loss) in the period incurred and reportedrecorded within other income and expense.(expense). Certain inter-company balances are designated as long-term.loans of a long-term investment-type nature. Accordingly, exchange gains and losses associated with these long-term inter-company balances are recorded as a component of other comprehensive income (loss), along with translation adjustments. How the U.S. dollar performs against certain of the currencies of the foreign countries in which the Company operates can have a significant impact to the Company. Strengthening and weakening of the U.S. dollar against theses currencies has significantly impacted the Company’s consolidated balance sheets (as evidenced in the Company’s foreign currency translation loss), as well as its consolidated statements of operations as amounts denominated in foreign currencies can increase or decrease the Company’s revenues and expenses. To the extent that the U.S. dollar strengthens or weakens further, this will continue to impact the Company’s consolidated balance sheets and consolidated statements of operations including the amount of revenue that the Company reports in future periods.

Basic EPS is computed using net income (loss) attributable to the Company and the weighted-average number of common shares outstanding. Diluted EPS is computed using net income, attributable to the Company, adjusted for interest expense as a result of the assumed conversion of the Company’s 3.00% Convertible Subordinated Notes andCompany's 4.75% Convertible Subordinated Notes, if dilutive, and the weighted-average number of common shares outstanding plus any dilutive potential common shares outstanding.

Redeemable Non-Controlling Interests
Non-controlling interests in subsidiaries that are redeemable for cash or other assets outside of the Company’s control are classified as mezzanine equity, outside of equity and liabilities, and are adjusted to fair value on each balance sheet date.

Recent Accounting Pronouncements
Accounting Standards Not Yet Adopted
In August 2017, Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2017-12 Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. This ASU was issued to improve the financial reporting of hedging relationships to better portray the economic results of an entity's risk management activities in its financial statements and to simplify the application of the hedge accounting guidance in current GAAP. This ASU permits hedge accounting for risk components involving nonfinancial risk and interest rate risk, requires an entity to present the earnings effect of the hedging instrument in the same income statement line item in which the hedged item is reported, no longer requires separate measurement and reporting of hedge ineffectiveness, eases the requirement for hedge effectiveness assessment, and requires a tabular disclosure related to the effect on the income statement of fair value and cash flow hedges. This ASU is effective for annual or any interim reporting periods beginning after December 15, 2018 with early adoption permitted. On January 1, 2019, the Company adopted this standard and is finalizing its evaluation of the impact that the adoption of this standard will have on its consolidated financial statements.
In June 2016, FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The ASU requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. The ASU requires enhanced disclosures to help investors and other financial statement users better understand significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an organization's portfolio. These disclosures include qualitative and quantitative requirements that provide additional information about the amounts recorded in the financial statements. In addition, the ASU amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. The ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019, with early adoption permitted for all organizations for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The Company will adopt this new ASU on January 1, 2019. The Company expects this ASU to impact its accounting for allowances for doubtful accounts and is currently evaluating the extent of the impact that the adoption of this standard will have on its consolidated financial statements, including its accounting policies, processes and systems.
In February 2016, the Financial Accounting Standards Board (“FASB”)FASB issued Accounting Standards Update (“ASU”)ASU 2016-02, Leases (Topic 842) ("ASU 2016-02"). and issued subsequent amendments to the initial guidance. Under the new guidance, lessees will be required to recognize the following for all leases (with the exception of short-term leases) at the commencement date: (1) a lease liability, which is a lessee‘slessee's future obligation to make lease payments arising from a lease, measured on a discounted basis; and (2) a right-of-use ("ROU") asset, which is an asset that represents the lessee’slessee's right to use, or control the use of, a specified asset for the lease term. UnderThe accounting applied by a lessor is substantially unchanged under Topic 842. The standard allows entities to adopt with one of two methods: the new guidance, lessor accounting is largely unchanged. Certain targeted improvements were made to align, where necessary, lessor accounting with the lessee accounting model and Topic 606, Revenue from Contracts with Customers. The new lease guidance simplified the accounting for sale and leaseback transactions primarily because lessees must recognize lease assets and lease liabilities. Lessees (for capital and operating leases) and lessors (for sales-type, direct financing, and operating leases) must apply a modified retrospective transition approach for leases existing at,method or entered into after, the beginning of the earliest comparative period presented in the financial statements.alternative transition method. The modified retrospective approach would not require any transition accounting for leases that expired before the earliest comparative period presented. Lessees and lessors may not apply a full retrospective transition approach. ASU 2016-02standard is effective for public companies for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, with early adoption permitted. While the Company is currently evaluating the impact that the adoption of this standard will have on its consolidated financial statements, the Company believes this standard will have a significant impact on its consolidated financial statements due, in part, to the substantial amount of operating leases it has.
In January 2016, the FASB issued ASU 2016-01, Financial Instruments- Overall (Subtopic 825-10) ("ASU 2016-01"), which requires all equity investments to be measured at fair value with changes in the fair value recognized through net income other than those accounted for under equity method of accounting or those that result in consolidation of the investees). The ASU also requires that an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments. In addition the ASU eliminates the requirement to disclose the fair value of financial instruments measured at amortized cost for entities that are not public business entities and the requirement to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet for public business entities. ASU 2016-01 is effective for public companies for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company is currently evaluating the impact that the adoption of this standard will have on its consolidated financial statements.

In November 2015, the FASB issued ASU 2015-17, Balance Sheet Classification of Deferred Taxes ("ASU 2015-17"), to simplify the presentation of deferred income taxes by eliminating the requirement to separate deferred tax assets and liabilities into current and noncurrent amounts. ASU 2015-17 requires that all deferred tax assets and liabilities, along with any related valuation allowance, be classified as noncurrent and is effective for financial statements issued for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. Earlier application is permitted as of the beginning of an interim or annual reporting period. The Company adopted ASU 2015-17 as of December 31, 2015 and applied the guidance prospectively.
In September 2015, the FASB issued ASU 2015-16, Business Combinations (“ASU 2015-16”), to simplify accounting for adjustments made to provisional amounts recognized in a business combination by eliminating the requirement to retrospectively account for those adjustments. This ASU is effective for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years with early adoption permitted. The amendments in this ASU require that the acquirer record, in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization or other income effects as a result of changes to provisional amounts, calculated as if the accounting had been completed at the acquisition date. The Company is currently evaluating the impact that the adoption of this standard will have on its consolidated financial statements.
In May 2015, the FASB issued ASU 2015-07, Fair Value Measurement (“ASU 2015-07”), which permits a reporting entity, as a practical expedient, to measure the fair value of certain investments using the net asset value per share of the investment. This ASU is effective for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years with early adoption permitted. A reporting entity should apply the amendment retrospectively to all periods presented. The retrospective approach requires that an investment for which fair value is measured using the net asset value per share practical expedient be removed from the fair value hierarchy in all periods presented in an entity’s financial statements. The Company does not believe the adoption of ASU 2015-07 will have a significant impact on its consolidated financial statements.
In April 2015, the FASB issued ASU 2015-03, Interest – Imputation of Interest (“ASU 2015-03”), to simplify the presentation of debt issuance costs. The ASU requires debt issuance costs to be presented in the balance sheet as a direct deduction from the carrying amount of the debt liability, consistent with debt discounts or premiums. The recognition and measurement guidance for debt issuance costs is not affected by this ASU. This ASU is effective for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within fiscal years beginning after December 15, 2016, with early adoption permitted. In August 2015, the FASB issued ASU 2015-15, Interest – Imputation of Interest Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements (“ASU 2015-15”), which amends ASU 2015-03 and provides guidance for the presentation of debt issuance costs associated with line-of-credit arrangements. ASU 2015-15 provides that debt issuance costs associated with line-of-credit arrangements may be presented in the balance sheet as assets. The Company adopted ASU 2015-03 and ASU 2015-15 in the three months ended September 30, 2015. As a result of the adoption of ASU 2015-03, the Company reclassified debt issuance costs of $35,455,000 at December 31, 2014 from other assets to debt. As of December 31, 2015, debt issuance costs of $47,028,000 were classified as a reduction of debt.
In February 2015, the FASB issued ASU 2015-02, Consolidations (“ASU 2015-02”). This ASU requires companies to adopt a new consolidation model, specifically: (1) the ASU modifies the evaluation of whether limited partnerships and similar legal entities are variable interest entities (VIEs) or voting interest entities; (2) the ASU eliminates the presumption that a general partner should consolidate limited partnership; (3) the ASU affects the consolidation analysis of reporting entities that involved with VIEs and (4) the ASU provides a scope exception from consolidation guidance for reporting entities with interests in legal entities that are required to comply with or operate in accordance with requirements that are similar Rule 2a-7 of the Investment Company Act of 1940 for registered money market funds. This ASU is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015, with early adoption permitted. The Company does not believe the adoption of ASU 2015-02 will have a significant impact on its consolidated financial statements.
In January 2015, the FASB issued ASU 2015-01, Income Statement – Extraordinary and Unusual Items (“ASU 2015-01”), to simplify the income statement presentation requirements by eliminating the concept of extraordinary items. ASU 2015-01 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015, with early adoption permitted provided that the guidance is applied from the beginning of the fiscal year of adoption. The Company does not believe the adoption of ASU 2015-01 will have a significant impact on its consolidated financial statements.
In August 2014, the Financial Accounting Standards Board (“FASB”) issued ASU 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (“ASU 2014-15”), to provide guidance on management’s responsibility in evaluating whether there is substantial doubt about a company’s ability to continue as a going concern and to provide related footnote disclosures.

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”). This ASU requires companies to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which companies expect to be entitled in exchange for those goods or services. This ASU will replace most existing revenue recognition guidance in GAAP when it becomes effective. This ASU was originally effective for fiscal years and interim periods beginning after December 15, 2016. In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers (“ASU 2015-14”), which amends ASU 2014-09 and defers its effective date to fiscal years and interim reporting periods beginning after December 15, 2017. ASU 2015-14 permits earlier application only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period.

Purchase Price Allocation


elected the land easements practical expedient which permits the Company not to assess at transition whether any expired or existing land easements are or contain leases if they were not previously accounted for as leases under Topic 840.
Upon the adoption of the new standard, the Company expects to derecognize build-to-suit assets and liabilities. Some build-to-suit leases are classified as operating leases, while some are classified as finance leases. The Company expects to recognize operating lease assets and liabilities of approximately $1.3 billion to $1.6 billion, which includes the derecognition of certain existing build-to-suit assets and liabilities subsequently assessed as operating leases. The Company is still finalizing its embedded lease assessment hence the above estimates exclude the potential impacts that might arise from the search for embedded, or previously unidentified, leases in existence as of adoption. In addition, the Company is still evaluating the impact of this standard on its financial statements as a lessor.
Accounting Standards Adopted
In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers ("ASU 2014-09") and issued subsequent amendments to the initial guidance, collectively referred as "Topic 606." Topic 606 replaces most existing revenue recognition guidance in U.S. GAAP. The core principle of Topic 606 is that an entity should recognize revenue for the transfer of control of the goods or services equal to the amount that it expects to be entitled to receive for those goods or services. Topic 606 requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments.
On January 1, 2018, the Company adopted Topic 606 using the modified retrospective approach applied to those contracts, which were not completed as of January 1, 2018, and recognized a net increase to the opening retained earnings of $269.8 million, net of tax impacts. Results for reporting periods beginning after January 1, 2018 are presented under Topic 606, while the comparative information has not been restated and continues to be reported under accounting standards in effect for those periods.
In adopting the new guidance, the Company elected to apply the practical expedient, which allows the company not to retrospectively restate contracts with multiple modifications on a modification by modification basis. Instead, the Company reflected the aggregate amount of all modifications that occurred before the beginning of the earliest period presented using the new standard. In addition, where appropriate, the Company elected to apply the practical expedient to account for the new standard under the portfolio approach as the Company reasonably expects that the effects of applying the guidance under the portfolio approach will not differ materially from applying the guidance to individual contracts. The Company also elected to apply the practical expedient that allows the Company not to disclose the remaining performance obligations for variable consideration that is allocated to entirely unsatisfied performance obligations or to a wholly unsatisfied distinct good or service that forms part of a single obligation.
The most significant impacts to the Company from Topic 606 relate to installation revenue and costs to obtain contracts. Under the new standard, the Company recognizes installation revenue over the contract period rather than over the estimated installation life as under the prior revenue standard. The Company is also required to capitalize and amortize certain costs to obtain contracts, rather than expense them immediately as under the previous standard.

The Company also adopted the following standards during 2018, none of which had a material impact to the Company's consolidated financial statements or financial statement disclosures:
StandardsDescriptionEffective Date and Adoption Consideration
ASU 2017-09 Compensation–Stock Compensation (Topic 718)This ASU was issued primarily to provide clarity and reduce both diversity in practice and cost and complexity when applying the guidance in Topic 718 to a change to the terms or conditions of a share-based payment award. This ASU affects any entity that changes the terms or conditions of a share-based payment award. This ASU provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718.January 1, 2018
ASU 2017-07 Compensation–Retirement Benefits (Topic 715)This ASU was issued primarily to improve the presentation of net periodic pension cost and net periodic post-retirement benefit cost. This ASU requires that an employer reports the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. It also requires the other components of net periodic pension cost and net periodic post-retirement benefit cost to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations, if one is presented. Additionally, only the service cost component is eligible for capitalization, when applicable.January 1, 2018
ASU 2017-05 Other Income—Gains and Losses from the Derecognition of Non-Financial Assets (Subtopic 610-20)This ASU is to clarify the scope of the non-financial asset guidance in Subtopic 610-20 and to add guidance for partial sales of non-financial assets. This ASU defines the term in substance non-financial asset and clarifies that non-financial assets within the scope of Subtopic 610-20 may include non-financial assets transferred within a legal entity to a counterparty. The ASU also provides guidance on the accounting for what often are referred to as partial sales of non-financial assets within the scope of Subtopic 610-20 and contributions of non-financial assets to a joint venture or other non-controlled investee.January 1, 2018
ASU 2017-04 Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment.This ASU is to simplify the subsequent measurement of goodwill. The ASU eliminates step 2 from the goodwill impairment test. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary.The Company elected to early adopt this ASU on a prospective basis, effective January 1, 2018.
ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a BusinessThis ASU provides new guidance to assist entities with evaluating when a set of transferred assets and activities is a business. The definition of a business affects many areas of accounting including acquisitions, disposals, goodwill and consolidation.The Company adopted this standard on a prospective basis, effective January 1, 2018. The adoption of this standard may impact the accounting of future transactions.
ASU 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than InventoryThis ASU requires the recognition of the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs.January 1, 2018
ASU 2016-01 Financial Instruments- Overall (Subtopic 825-10)

This ASU requires all equity investments to be measured at fair value with changes in the fair value recognized through net income other than those accounted for under equity method of accounting or those that result in consolidation of the investees. The ASU also requires that an entity present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments.The Company adopted this standard using the modified retrospective method, effective January 1, 2018 and recorded a net increase to retained earnings of $2.1 million.

Includes cumulative adjustments made to these accounts on January 1, 2018 from the adoption of Topic 606.
The difference between the opening and closing balances of the Company's accounts receivable, net, contract assets and deferred revenues primarily results from the timing difference between the satisfaction of the Company's performance obligation and the customer's payment, as well as business combinations closed during the year ended December 31, 2018. The amounts of revenue recognized during the year ended December 31, 2018 from the opening deferred revenue balance was approximately $81.8 million. For the year ended December 31, 2018, no impairment loss related to contract balances was recognized in the consolidated statement of operations.
Contract Costs
The ending balance of net capitalized contract costs as of December 31, 2018 was $188.2 million, which was included in other assets in the consolidated balance sheet. For the year ended December 31, 2018, $73.1 million of contract costs were amortized, which were included in sales and marketing expense in the consolidated statement of operations.
Remaining performance obligations
As of December 31, 2018, approximately $5.8 billion of total revenues and deferred installation revenues are expected to be recognized in future periods, the majority of which will be recognized over the next 24 months. While initial contract terms vary in length, substantially all contracts thereafter automatically renew in one-year increments. Included in the remaining performance obligations is either 1) remaining performance obligations under the initial contract terms or 2) remaining performance obligations related to contracts in the renewal period once the initial terms have lapsed. The remaining performance obligations do not include variable consideration related to unsatisfied performance obligations such as the usage of metered power or any contracts that could be terminated without any significant penalties such as the majority of interconnection revenues. The remaining performance obligations above exclude approximately $1.2 billion total revenues to be recognized in the future related to arrangements where the Company is the lessor.
3.Acquisitions

On April 2, 2018, the Company completed the acquisition of Infomart Dallas, including its operations and tenants, from ASB Real Estate Investments, for total consideration of approximately $804.0 million. The consideration was comprised of approximately $45.8 million in cash, subject to customary adjustments and $758.2 million aggregate fair value of 5.000% senior unsecured notes (see Note 11). Prior to the acquisition, a portion of the building was leased to the Company and was being used as its Dallas 1, 2, 3 and 6 data centers, which were all accounted for as build-to-suit leases. Upon acquisition, the Company effectively terminated the leases and settled the related financing obligations and other liabilities related to the leases for approximately $170.3 million and $1.9 million, respectively, and recognized a loss on debt extinguishment of $19.5 million. The acquisition of this highly interconnected facility and tenants adds to the Company's global platform and secures the ability to further expand in the Americas market in the future.
Both acquisitions constitute a business under the accounting standard for business combinations and, therefore, were accounted for as business combinations using the acquisition method of accounting. Under the acquisition method of accounting, the total purchase price wasis allocated to Bit-isle’s net tangiblethe assets acquired and intangible assets based upon theirliabilities assumed measured at fair value ason the date of acquisition.

The fair value measurements were based on significant inputs that are not observable in the market and thus represent Level 3 measurements as defined in the accounting standard for fair value measurements.
The Company determinedfair value of property, plant and equipment was estimated by applying the cost approach, with the exception of land which was estimated by applying the market approach, for the Metronode Acquisition. For the Infomart Dallas Acquisition, the fair values of land, building and personal property were estimated by applying the market approach, residual income method and cost approach, respectively. The cost approach uses the replacement or reproduction cost as an indicator of fair value. The premise of the cost approach is that a market participant would pay no more for an asset than the amount for which the asset could be replaced or reproduced. The key assumptions of the cost approach include replacement cost new, physical deterioration, functional and economic obsolescence, economic useful life, remaining useful life, age and effective age. The residual income method estimates the fair value of the loans payable assumed inInfomart Dallas building using an income approach less the Bit-isle Acquisition by estimating Bit-isle’s debt ratingfair values attributed to land, personal property, in-place leases and reviewed market data with a similar debt ratingfavorable and other characteristicsunfavorable leases.

The adjustments made primarily resulted in a decrease in property, plant and equipment, other assets, other liabilities and deferred tax assets of $10.1 million, $10.0 million, $9.7 million and $4.1 million, respectively, and an increase in goodwill, deferred tax liabilities and intangible assets of $45.3 million, $35.4 million and $4.8 million, respectively, for the Metronode Acquisition. The adjustments for the Infomart Dallas Acquisition primarily resulted in a decrease in goodwill of $6.2 million and an increase in intangible assets of $4.6 million. The changes in fair value of acquired assets and liabilities assumed did not have a significant impact on the Company's results of operations for any reporting periods prior to December 31, 2018.

subject to certain exceptions, during the five business day period following any 10 consecutive trading day period in which the trading price of the 4.75% Convertible Subordinated Notes for each day of such period was less than 98% of the product of the sale price of the Company’s common stock and the conversion rate (the “4.75% Convertible Subordinated Notes Parity Provision Clause”);
upon the occurrence of specified corporate transactions described in the 4.75% Convertible Subordinated Notes Indenture, such as a consolidation, merger or binding share exchange in which the Company’s common stock would be converted into cash or property other than securities (the “Corporate Action Provision Clause”); or
at any time on or after March 15, 2016.
Upon conversion, if the Company elected to pay a sufficiently large portion of the conversion obligation in cash, additional consideration beyond the gross proceeds received would be required.
Holders of the 4.75% Convertible Subordinated Notes were eligible to convert their notes during the year ended December 31, 2015 and are eligible to convert their notes during the three months ending March 31, 2016, since the Stock Price Condition Conversion Clause was met during the applicable periods. As of December 31, 2015, had the holders of the remaining outstanding 4.75% Convertible Subordinated Notes converted their notes, the 4.75% Convertible Subordinated Notes would have been convertible into a maximum of 1,960,896 shares of the Company’s common stock.
The conversion rates may be adjusted upon the occurrence of certain events, including for any cash dividend, but they will not be adjusted for accrued and unpaid interest. Holders of the 4.75% Convertible Subordinated Notes will not receive any cash payment representing accrued and unpaid interest upon conversion of a note. Accrued but unpaid interest will be deemed to be paid in full upon conversion rather than canceled, extinguished or forfeited.
The Company does not have the right to redeem the 4.75% Convertible Subordinated Notes at its option. Holders of the 4.75% Convertible Subordinated Notes have the right to require the Company to purchase with cash all or a portion of the 4.75% Convertible Subordinated Notes upon the occurrence of a fundamental change, such as a change of control at a purchase price equal to 100% of the principal amount of the 4.75% Convertible Subordinated Notes plus accrued and unpaid interest, if any, to, but excluding, the date of repurchase. Following certain corporate transactions that constitute a change of control, the Company will increase the conversion rate for a holder who elects to convert the 4.75% Convertible Subordinated Notes in connection with such change of control in certain circumstances.
Under an accounting standard for convertible debt instruments that may be settled in cash upon conversion (including partial cash settlement), the Company separated the 4.75% Convertible Subordinated Notes into a liability component and an equity component. The carrying amount of the liability component was calculated by measuring the fair value of a similar liability (including any embedded features other than the conversion option) that does not have an associated equity component. The carrying amount of the equity component representing the embedded conversion option was determined by deducting the fair value of the liability component from the initial proceeds ascribed to the 4.75% Convertible Subordinated Notes as a whole. The excess of the principal amount of the liability component over its carrying amount is amortized to interest expense over the expected life of a similar liability that does not have an associated equity component using the effective interest method. The equity component is not remeasured as long as it continues to meet the conditions for equity classification as prescribed in the accounting standard for derivative financial instruments indexed to, and potentially settled in, an entity’s own common stock and the accounting standard for determining whether an instrument (or embedded feature) is indexed to an entity’s own stock.
In May and June 2014, certain holders of the 4.75% Convertible Subordinated Notes elected to convert a total of $215,830,000$223.7 million of the principal amount of the notes for 2,411,8512,513,798 shares of the Company’sCompany's common stock and $51,671,000$51.7 million in cash, comprised of accrued interest, premium and cash paid in lieu of issuing shares for certain note holders’holders' principal amount. As a result, the Company recognized a loss on debt extinguishment of $46,973,000 for the year ended December 31, 2014 in its consolidated statement of operations. The loss on debt extinguishment included the premium paid

Stock-Based Compensation Recognized in the Consolidated Statement of Operations
The Company generally recognizes stock-based compensation expense on a straight-line basis over the requisite service period of the awards. However, for awards with market conditions or performance conditions, stock-based compensation expense is recognized on a straight-line basis over the requisite service period for each vesting tranche of the award.
In October 2014, the Compensation Committee approved amendments to the terms of all outstanding restricted stock units (“RSUs”) granted prior to January 1, 2014 to provide for dividend equivalent rights (“DERs”) in the event of future dividends paid on the Company’s common stock.  The Compensation Committee also approved an adjustment to outstanding stock options, including those under the Company’s Employee Stock Purchase Plan (“ESPP”), to ensure that the cash portion of the 2014 Special Distribution would not negatively impact the intrinsic value of the options. Pursuant to the accounting standard for stock compensation, these actions affecting the terms of the awards are considered modifications for accounting purposes that resulted in incremental stock-based compensation expenses and will be recognized over the requisite service period for each vesting tranche of the award. The total charges associated with this modification are insignificant to the financial statements.
As of December 31, 2015,2018, the total stock-based compensation cost related to unvested equity awards not yet recognized, net of estimated forfeitures, totaled $201,206,000$337.8 million which is expected to be recognized over a weighted-average period of 2.082.14 years.

13.     Income Taxes
In September 2012, the Company announced that its Board of Directors approved a plan for Equinix to pursue conversion to a REIT. On December 23, 2014, its Board of Directors formally approved its conversion to a REIT effective on January 1, 2015. The Company completed the implementation of the REIT conversion in 2014, and, as a result, the Company elected to be treated as a REIT for federal income tax purposes effective January 1, 2015.
In May 2015, the Company received a favorable PLR from the IRS in connection with the Company’s conversion to a REIT for federal income tax purposes. As a result, the Company may deduct the distributions made to its shareholders from taxable income generated by the Company and its QRSs. The Company’s dividends paid deduction generally eliminates the taxable income of the Company and its QRSs, resulting in no U.S. income tax due. However, the TRSs will continue to be subject to income taxes on any taxable income generated by them. In addition, the foreign operations of the Company will continue to be subject to local income taxes regardless of whether the foreign operations are operated as a QRS or a TRS.

The Company had not previously provided for deferred taxesLegislation commonly referred to as the Tax Cuts and Jobs Act ("TCJA"), which was signed into law on December 22, 2017, contained many significant changes to the excess ofU.S. federal income tax laws. Among other things, the financial reporting overTCJA reduced the U.S. corporate income tax rate from 35% to 21% effective January 1, 2018, limited the tax basis in its investments in foreign subsidiaries that are essentially permanent in duration because the Company intended to reinvest the earnings outsidedeductibility of interest expense, accelerated expensing of certain business assets and transitioned the U.S. for an indefinite periodinternational taxation from a worldwide tax system to a territorial tax system by imposing a one-time mandatory repatriation of time.undistributed foreign earnings. As a result of the Company’sreduced corporate tax rate, the Company recognized an income tax expense of $6.5 million during the fourth quarter of 2017 as a provisional estimate due to the remeasurement of the net deferred tax assets in the U.S. TRS. In the fourth quarter of 2018, the Company has completed the analysis of the TCJA's income tax effects and recorded an additional $1.3 million as an adjustment to the provisional amount related to the remeasurement of the net deferred tax assets in the U.S. TRS.
The TCJA mandated a one-time deemed repatriation of undistributed foreign earnings, which increased the Company's 2017 taxable income, as well as its required REIT distribution. In the fourth quarter of 2017, the Company estimated a provisional amount of $195.0 million as the one-time mandatory repatriation of its cumulative foreign earnings that was not previously included in the U.S. taxable income. In the fourth quarter of 2018, the Company completed the analysis based on the interpretation and guidance issued during 2018 and determined the one-time mandatory repatriation of its cumulative foreign earnings to be $271.8 million. The Company had an option of including the entire amount in its 2017 taxable income or spreading the amount over 8 years in its taxable income. The Company has included the entire amount in its 2017 taxable income. The Company believes the mandatory repatriation resulted in no financial statement impact because the Company satisfied its REIT distribution requirement and paid out such amounts (net of the permitted one-time participation deduction) to its stockholders.
The TCJA included a Global Intangible Low-Taxed Income ("GILTI") provision that increases U.S. federal taxable income by certain foreign subsidiary income in the year it is earned. The Company's accounting policy is to treat any tax on GILTI inclusions as a current period cost included in the tax expense in the year incurred. The Company believes the GILTI inclusion provision will result in no financial statement impact provided the Company satisfies its REIT distribution requirement with respect to the GILTI inclusions.
As a result of the Company's conversion to a REIT effective January 1, 2015, it is no longer the Company’sCompany's intent to indefinitely reinvest undistributed foreign earnings from its operations in Europe and Canada.earnings. However, no deferred tax liability has been recognized to account for this change because the expected recovery of the basis difference will not result in U.S. taxes in the post-REIT conversion periods. As itperiods because none of its foreign subsidiaries is owned by a U.S. taxable REIT subsidiary and the withholding tax effect would be immaterial. The Company continues to qualify as a REIT, the Company will not incur U.S. tax liability on the future repatriation ofassess the foreign earningswithholding tax impact of its current policy and profitsdoes not believe the distribution of the above noted jurisdictions due to the zeroits foreign

2018.
The Company's accounting for deferred taxes involves weighing positive and negative evidence concerning the realizability of the Company's deferred tax assets in each tax jurisdiction. After considering such evidence as the nature, frequency and severity of current and cumulative financial reporting losses, and the sources of future taxable income and tax planning strategies, managementthe Company concluded that valuation allowances were required in certain foreign jurisdictions. A valuation allowance continues to be provided for the deferred tax assets, net of deferred tax liabilities, associated with the Company's operations in certain jurisdictions located in the Company’s EMEA and Asia-Pacific regions, as well as two entities in Brazil. The operations in thesethe jurisdictions for which a valuation allowance has been established have a history of significant losses as of December 31, 2015.2018. As such, managementthe Company does not believe these operations have established a sustained history of profitability and that a valuation allowance is, therefore, necessary. The Company also provided a full valuation allowance against certain gross deferred tax assets acquired in the Metronode Acquisition as these deferred tax assets are not expected to be realizable in the foreseeable future.
Changes in the valuation allowance for deferred tax assets for the years ended December 31, 2015, 20142018, 2017 and 20132016 are as follows (in thousands):

Federal and state tax laws, including California tax laws, impose substantial restrictions on the utilization of net operating lossNOL and credit carryforwards in the event of an "ownership change" for tax purposes, as defined in Section 382 of the Internal Revenue Code. An ownership change occurred during fiscal year 2002, which resulted in an annual limitation of approximately $0.8 million for NOL carryforwards generated prior to 2003.

Revenue Code. In 2003, the Company conducted an analysis to determine whether an ownership change had occurred due to significant stock transactions in each of the reporting years disclosed at that time. The analysis indicated that an ownership change occurred during fiscal year 2002, which resulted in an annual limitation of approximately $819,000 for net operating loss carryforwards generated prior to 2003. Therefore, the Company substantially reduced its federal and state net operating loss carryforwards for the periods prior to 2003 to approximately $16,400,000. In addition, an ownership change under Section 382 of the Internal Revenue Code was triggered in September 2007 by the issuance of 4,211,939 shares of the Company's common stock. However, the annual limitation associated with this ownership change is not meaningful due to the substantial market capitalization of the Company at the time of the ownership change. The Company determined that no Section 382 ownership change occurred during the year ended December 31, 2015. In addition, the net operating loss acquired in the Switch and Data acquisition in 2010 is subject to the Section 382 limitation; however, the Company has determined that none of the acquired net operating losses will expire unused as a result of the limitation.
The Company utilized all of its net operating loss carryforwards that were not subject to the limitation under Section 382 as discussed above for federal income tax purposes during the year ended December 31, 2013. The Company’s U.S. operations generated significant taxable income (versus book income) for the years ended December 31, 2015 and 2014 primarily due to the change in the tax method for depreciation of the Company’s property, plant and equipment. As the result of announcing its plan to pursue a REIT conversion, the Company changed its methods of depreciating and amortizing various data center assets to methods that are more consistent with the characterization of such assets as real property for REIT purposes. The change in the depreciation method resulted in the recapture of depreciation expense deducted in prior years and a much smaller amount of depreciation expense for the years ended December 31, 2015 and 2014.

Approximately $4,443,000 of the total net operating loss carryforwards is attributable to excess tax deductions related to employee stock awards, the benefit from which will be credited to additional paid-in capital when subsequently utilized in future years.

The Company recognizes interest and penalties related to unrecognized tax benefits within income tax benefit (expense) in the consolidated statementstatements of operations. During the years ended December 31, 2015, 2014 and 2013, the accrued interest and penalties related to the unrecognized tax benefits were decreased by $1,701,000, $3,126,000 and $1,612,000, respectively, primarily resulting from the settlement of tax audits and the lapse of statutes of limitations in its foreign operations. The Company has accrued $3,736,000$8.4 million and $5,437,000$2.9 million for interest and penalties accrued atas of December 31, 20152018 and 2014,2017, respectively.
The unrecognized tax benefits of $30,845,000$114.9 million as of December 31, 2015,2018, if subsequently recognized, will affect the Company's effective tax rate favorably at the time when such a benefit is recognized.
Due to various tax years open for examination, it is reasonably possible that the balance of unrecognized tax benefits could significantly increase or decrease over the next 12 months as the Company may be subject to either examination by tax authorities, tax audit settlements, or a lapse in statute of limitations. The Company is currently unable to estimate the range of possible adjustments to the balance of unrecognized tax benefits.

Purchase Commitments
Primarily as a result of the Company’sCompany's various IBX expansion projects, as of December 31, 2015,2018, the Company was contractually committed for $256,757,000$0.7 billion of unaccrued capital expenditures, primarily for IBX equipment not yet delivered and labor not yet provided, in connection with the work necessary to open these IBX data centers and make them available to customers for installation. In addition, the Company had numerous other, non-capital purchase commitments in place as of December 31, 2015,2018, such as commitments to purchase power in select locations, primarily in select locations through 20162019 and thereafter, and other open purchase orders for goods, services or servicesarrangements that may contain embedded leases to be delivered or provided during 20162019 and thereafter. Such other miscellaneous purchase commitments totaled $352,202,000$0.8 billion as of December 31, 2015.2018. In addition, the Company entered into lease agreements in various locations for a total lease commitment of approximately $262.2

million, excluding potential lease renewals. These lease agreements will commence between February 2019 and May 2020 with lease terms of 5 to 30 years.
Contingent Liabilities
The Company estimates exposure on certain liabilities, such as incomeindirect and property taxes, based on the best information available at the time of determination. With respect to real and personal property taxes, the Company records what it can reasonably estimate based on prior payment history, current landlord estimates or estimates based on current or changing fixed asset values in each specific municipality, as applicable. However, there are circumstances beyond the Company’sCompany's control whereby the underlying value of the property or basis for which the tax is calculated on the property may change, such as a landlord selling the underlying property of one of the Company’sCompany's IBX data center leases or a municipality changing the assessment value in a jurisdiction and, as a result, the Company’sCompany's property tax obligations may vary from period to period. Based upon the most current facts and circumstances, the Company makes the necessary property tax accruals for each of its reporting periods. However, revisions in the Company’sCompany's estimates of the potential or actual liability could materially impact the financial position, results of operations or cash flows of the Company.
The Company's indirect and property tax filings in various jurisdictions are subject to examination by local tax authorities. The outcome of any examinations cannot be predicted with certainty. The Company regularly assesses the likelihood of adverse outcomes resulting from these examinations that would affect the adequacy of its tax accruals for each of the reporting periods. If any issues arising from the tax examinations are resolved in a manner inconsistent with the Company's expectations, the revision of the estimates of the potential or actual liabilities could materially impact the financial position, results of operations, or cash flows of the Company.
From time to time, the Company may have certain contingent liabilities that arise in the ordinary course of its business activities. The Company accrues contingent liabilities when it is probable that future expenditures will be made and such expenditures can be reasonably estimated. In the opinion of management, there are no pending claims for which the outcome is expected to result in a material adverse effect in the financial position, results of operations or cash flows of the Company.
Employment Agreements
The Company has entered into a severance agreement with each of its executive officers that provides for a severance payment equal to the executive officer’sofficer's annual base salary and maximum bonus in the event his or her employment is terminated for any reason other than cause or he or she voluntarily resigns under certain circumstances as described in the agreement. In addition, under the agreement, the executive officer is entitled to the payment of his or her monthly health care premiums under the Consolidated Omnibus Budget Reconciliation Act for up to 12 months. For certain executive officers, these benefits are only triggered after a change-in-control of the Company.

Indemnification and Guarantor Arrangements
As permitted under Delaware law, the Company has agreements whereby the Company indemnifies its officers and directors for certain events or occurrences while the officer or director is, or was serving, at the Company’sCompany's request in such capacity. The term of the indemnification period is for the officer's or director's lifetime. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is unlimited; however, the Company has a director and officer insurance policy that limits the Company’sCompany's exposure and enables the Company to recover a portion of any future amounts paid. As a result of the Company’sCompany's insurance policy coverage, the Company believes the estimated fair value of these indemnification agreements is minimal. The Company has no liabilities recorded for these agreements as of December 31, 2015.2018.
The Company enters into standard indemnification agreements in the ordinary course of business. Pursuant to these agreements, the Company indemnifies, holds harmless, and agrees to reimburse the indemnified party for losses suffered or incurred by the indemnified party, generally the Company’sCompany's business partners or customers, in connection with any U.S. patent, or any copyright or other intellectual property infringement claim by any third party with respect to the Company’sCompany's offerings. The term of these indemnification agreements is generally perpetual any time after execution of the agreement. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is unlimited; however, the Company has never incurred costs to defend lawsuits or settle claims related to these indemnification agreements. As a result, the Company believes the estimated fair value of these agreements is minimal. The Company has no liabilities recorded for these agreements as of December 31, 2015.2018.

The Company enters into arrangements with its business partners, whereby the business partner agrees to provide services as a subcontractor for the Company’s implementations.Company's installations. Accordingly, the Company enters into standard indemnification agreements with its customers, whereby the Company indemnifies them for other acts, such as personal property damage, of its subcontractors. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is unlimited; however, the Company has general and umbrella insurance policies that enable the Company to recover a portion of any amounts paid. The Company has never incurred costs to defend lawsuits or settle claims related to these indemnification agreements. As a result, the Company believes the estimated fair value of these agreements is minimal. The Company has no liabilities recorded for these agreements as of December 31, 2015.2018.
The Company has service level commitment obligations to certain of its customers. As a result, service interruptions or significant equipment damage in the Company’sCompany's IBX data centers, whether or not within the Company’sCompany's control, could result in service level commitments to these customers. The Company’sCompany's liability insurance may not be adequate to cover those expenses. In addition, any loss of services, equipment damage or inability to meet the Company’sCompany's service level commitment obligations could reduce the confidence of the Company’sCompany's customers and could consequently impair the Company’sCompany's ability to obtain and retain customers, which would adversely affect both the Company’sCompany's ability to generate revenues and the Company’sCompany's operating results. The Company generally has the ability to determine such service level credits prior to the associated revenue being recognized. The Company has nodoes not have significant liabilities in connection with service level credits as of December 31, 2015.2018.

During the years ended December 31, 2015 and 2014, the Company did not record any restructuring charges.
2004 Restructuring Charge
In December 2004, in light of the availability of fully built-out data centers in select markets at costs significantly below those costs the Company would incur in building out new space, the Company made the decision to exit leases for excess space adjacent to one of the Company’s New York metro area IBXs, as well as space on the floor above its original Los Angeles IBX. As a result of the Company’s decision to exit these spaces, the Company recorded restructuring charges totaling $17,685,000, which represents the present value of the Company’s estimated future cash payments, net of estimated sublease income and expense, through the remainder of these lease terms, as well as the write-off of all remaining property, plant and equipment attributed to the partial build out of the excess space on the floor above its Los Angeles IBX.
In May 2013, the Company entered into a binding commitment to purchase the New York 2 IBX data center for leased space in respect of which the Company had previously recorded a restructuring reserve. As a result, the Company recorded a reversal to its outstanding accrued restructuring charge during the year ended December 31, 2013.
A summary of the movement in the 2004 accrued restructuring charges during the year ended December 31, 2013 is outlined as follows (in thousands):

19.Quarterly Financial Information (Unaudited)
The Company believes that period-to-period comparisons of its financial results should not be relied upon as an indication of future performance. The Company’sCompany's revenues and results of operations have been subject to significant fluctuations, particularly on a quarterly basis, and the Company’sCompany's revenues and results of operations could fluctuate significantly quarter-to-quarter and year-to-year. Significant quarterly fluctuations in revenues will cause fluctuations in the Company’sCompany's cash flows and the cash and cash equivalents and accounts receivable accounts on the Company’sCompany's consolidated balance sheet. Causes of such fluctuations may include the volume and timing of new orders and renewals, the timing of the opening of new IBX data centers, the sales cycle for the Company’sCompany's offerings, the introduction of new offerings, changes in prices and pricing models, trends in the Internetinternet infrastructure industry, general economic conditions, extraordinary events such as acquisitions or litigation and the occurrence of unexpected events.
